The order of brickwork is 1.5 bricks. Brickwork corners. Mortar for brickwork

The laying of wall corners is carried out by qualified masons with sufficient experience. After all, the future walls of the house depend on the quality of the construction of the corners. For this reason, it is necessary to approach the layout of the corners of the house, and then during construction, with all responsibility.

To bandage the seams of vertical restrictions, places of abutment and intersection of walls, pillars and piers, incomplete bricks are required: quarters, halves and three-quarters.

Masons prepare them directly on the job site. For quarters, three quarters, and halves, bricks with broken corners or other defects are used. Three-quarter bricks and other incomplete bricks are laid with the broken side inside the masonry, and the whole side facing out.

Basically, when laying corners, a single-row (chain) or multi-row masonry ligation system is used, which is less labor-intensive than a single-row one.

The sequence of laying corners and wall boundaries is shown in the figures.

Scheme right angle and restrictions for single-row ligation of masonry in 1 brick.

Scheme of a right angle and restrictions for single-row ligation of masonry of 1.5 bricks. Scheme of a right angle and restrictions for single-row ligation of masonry of 2 bricks.

Typically, during construction brick walls the laying of the corners is ahead of the laying of the walls by 3-4 rows. In the article How to make brick walls for a bathhouse, some useful tips on laying out corners, and in the publication Brickwork Banding Systems you can find not only schemes for bandaging seams at intersections and junctions, but also schemes for correct bandaging when laying corners of walls of 1.5 and 2 bricks. Let's look at a few more schemes for laying brick corners walls of different thicknesses. To perform bandaging of masonry seams in the corners, not only full-size bricks are used, but also halves and quarters of bricks, as well as three-fours the size of ¾ bricks. Symbol bricks of various sizes are shown in the figure below: Laying a corner with 1 brick The simplest is laying corners when building walls with a thickness of 1 brick (250 mm). The diagram for laying corners in 1 brick with single-row ligation is shown below: With multi-row ligation, laying corners in 1 brick will look like this: As you can see, the diagrams are quite simple and you can easily lay out tie and spoon rows yourself with your own hands without involving a team of qualified masons.

Laying a corner of 1.5 bricks

When building walls of 1.5 bricks (380 mm), the layout of the corners will be somewhat more complex.

How to make corners of 1.5 bricks with a single-row dressing is shown in the figure below:

When brick objects are built, regardless of its purpose and type, for example, a house or a fence, a question always arises related to correct masonry corner. It is how well the brickwork of the corners is done that determines the possibility of even laying of the wall itself, the strength and stability of the folded object. Photo of a beautiful corner masonry Tip: If you act as a novice mason, then you should carry out a trial, “dry” test before the actual work. , masonry, that is, without using mortar. Otherwise, the cost of the mistake will exceed the savings. To bandage the masonry seams in places such as vertical restrictions, junctions and intersections of walls. And of course where the masonry is done brick corners, you need incomplete bricks. This material is one quarter, half and three quarters of the whole.

To obtain them, they usually use material that has broken corners or any other defects. This is done for the sake of economy. One of the qualities of a mason is the skill of accurately determining the size of such an incomplete brick and cutting it off correctly. Otherwise, if such material has inaccurate dimensions, there will be a violation of the ligation of seams and an increase in mortar consumption. All this will lead to a decrease in the strength of the brickwork. Incomplete material and its symbols The following figure shows how you can chop and hew brick, respectively, instructions for cutting bricks with your own hands: To correctly determine the length of an incomplete briquette, the hammer handle contains special notches that correspond to the length necessary parts. The line along which the brick will be cut is marked with a hammer blade. Then a notch is made, for which the hammer hits the spoon on both sides. Then, with the help of a strong blow, the brick is cut according to the marked line. Attention: During the cutting process, the direction of the hammer upon impact, it must be perpendicular to the spoon. Otherwise, the resulting briquette will have an oblique end. If it is necessary to cut lengthwise, first light blows are applied to all four planes, after which a strong and short blow is made along the cutting line. How to properly chop the material Corner brickwork Corner brickwork is divided into two types, depending on the use of the ligation method. Single-row ligation When using a single-row ligation, when deciding how to lay out a brick corner, perform the following steps: It is necessary to pass the masonry of the adjacent wall through the main wall and to the front side.

It ends with three-quarter or tying material if fours or three-fours are used. In the next row, a row of the wall that is adjacent is laid to the spoons of the main wall. The following actions are performed alternately. Constructing corners using a single-row dressing Multi-row dressing The actions are as follows: The first row is laid out in the same way as it was carried out actions during single-row dressing, though only if the thickness of the walls is calculated in whole bricks. Attention is drawn to the fact that the backfill of the second row is laid out with bricks, and the inner and outer verst - with spoons. If the thickness of the walls is not a multiple of the brick, then the butts of the first row are laid out outside the facade, and the butts of the second row look inside the room, which means that the spoons are accordingly placed outwards Next, the third and up to the sixth row are laid out only with spoons. And at the same time, the vertical transverse seams are ligated either by a quarter or half of the briquette. After the sixth row is laid, the cycle is repeated, starting from the first point. Tip: If the loads on the wall are small, then in areas where the windows are located, the backfill can be filled with either halves or bricks. Corner tiles like bricks can also be used. Multi-row dressing of a corner of 1.5 bricks Multi-row dressing of a corner of 2 bricks Some nuances of corner masonry It must be said that the vertical limitation is set in the first two rows laid out three-fours starting both the first and second rows.

For the remaining spoon rows, the restrictions alternate. From them, a partial brick with a whole is laid with a spoon, and the spoons should overlap by half of the brick. A right angle is laid out using quarter and three-quarter bricks. The corner begins with two three-quarter corners, with each of them placed with a spoon in the direction of the outer mile of the corresponding wall.

Between the tying and three-quarter briquettes, the gap that appears is filled with quarter briquettes. The filling of the next row is usually done with tying, and the versts with spoons. After this, the vertical seams are bandaged, using spoon rows. If the inner wall is connected to the outer wall using double sand-lime brick M 150, then such a connection is performed as a single-row or multi-row fine. Therefore, a steel mesh is laid every meter or one and a half. Fines for joining walls. It must be remembered that corner masonry (no matter what building brick used) must be vertical.

To check verticality, it is worth using a plumb line, since it shows the vertical better than the building level. Otherwise, the corner may be blocked and, if there is a heavy load, the entire wall may fall on its side. For the same thing, it is possible to use a straight metal corner, which is attached at the bottom to at least five masonry rows. And then leveling the vertical will take you much less time. Conclusion Corner masonry should be treated very responsibly, because its execution determines how smooth, beautiful and stable your walls will be. In the video presented in this article you will find additional information on this topic .

Laying bricks in the corners of a building is a very important and responsible process.

When building a house, the cutting of corners is entrusted to the most qualified and experienced masons. The strength and evenness of the laid brick walls directly depends on how smoothly the corners are laid out and how the rows are tied in them correctly. If the masonry of the corners is not strictly vertical, then it will not only look unsightly, but will most likely collapse, pulling the wall with it.

Therefore, you need to carefully check and control all stages of the work, starting from the layout, the quality of the laid material (for corners you need only selected material, without cracks, chips, chips and other defects) and rechecking the vertical every 2-3 laid rows.

Organization of the work area

High-quality brickwork will be very difficult without proper organization working area.

This zone includes the brick house itself, which is being built, and an area within 2.5-3 m from the walls being driven out, on which the necessary tools and materials will be placed. If the area is smaller, something will constantly interfere with your work; if you make it larger, then bringing materials will be far away and inconvenient. In both cases, this will significantly affect the pace of construction of a brick house.

The work area is divided into three parts. The first, within 0.5 m, is the space that will be occupied by scaffolding.

Within these limits there should be no large piles of materials, no buckets of solution, or bulky tools. The second, approximately 1.5 m, zone of materials and tools. The third, 0.5-1 m, is a buffer between the first and second zones, the main task of which is to ensure the free and uninterrupted delivery of materials to the house under construction.

High-quality bricklaying of corners will be impossible if at least one of the necessary tools is not available:

trowel; jointing; container for preparing mortar; container for supplying mortar to the masonry; scraping; hammer-pick; building level; tape measure; plumb line; square.

When carrying out work, especially when you have to climb scaffolding, you need to be extremely careful. The slightest carelessness or overconfidence can cause serious injury.

Since the brickwork of corners, as part of the walls, always begins with laying the first row on the plinth, before it begins, it is better to beat off the outer boundaries of the walls with a cord. When outlining the boundaries, you must ensure that the intersecting lines form angles of strictly 90º. You also need to align the diagonals with a cord.

When laying a brick house, especially for those who do not have sufficient experience, they should start with a trial layout. Those. simply place the bricks of the first row on the plinth, at a distance of 10 mm from each other, without sitting them on the mortar. This way you will see the whole picture, where and what size inserts need to be made, since even the most experienced and qualified mason will not be able to make masonry using only whole bricks, without inserts of quarters, halves and three-quarters.

Be especially careful when laying corners.

The complexity of this construction operation lies in the fact that it is necessary to lay inserts made of quarters and three-quarters. Therefore, in the corners it is better to perform a test layout to a height of 3-4 rows, while experimenting with how best to bandage the vertical seams. And only after fully assessing the situation and remembering the location of the bricks can you get to work.

Before starting work, it is advisable to moisten the base with water. If this is not done, the base will draw moisture from the solution placed on it. The solution itself is placed on the base with a trowel, while making sure that a strip 15-20 mm from the outer edge of the base remains free.

First, two bricks (or a brick and an insert) are taken and placed in the corner, pressed against the mortar.

When laid, they should form a right angle. Use the handle of a trowel to lightly tap them, and then fill the gap between them with mortar. Be sure to check the horizontal lines using a level.

You need to place 3-4 bricks on each side of the corner, making sure to control the evenness of their horizontals and verticals. Then, following the dressing scheme, row 2 is laid on top, then row 3, etc.

We should not forget about aligning the seams. This is done by scraping and jointing while the solution is still soft. The easiest way is to slightly recess the seams into the masonry, for which you just need to run a jointer over them and wipe off the excess mortar from the wall.

The direction of the work does not really matter; do it the way that is most convenient for you. For right-handed people, it is better to build a brick house from right to left, for left-handed people - vice versa. If a team of masons is working, then 5-6 rows are simultaneously driven out in all 4 corners, and then the walls are built up row by row, observing the initial gap (the corners should be 5-6 rows ahead of the wall) until the work is completed.

Well brick masonry walls according to the A.S. system. Vlasova. But alone she cannot cope with such a volume of work at the same time. Therefore, use the following order: first, drive out 2 corners to the desired height, then place 1-2 rows of bricks between them, drive out the 3rd corner and connect it with the same number of rows to 2, then drive out the 4th corner and connect it to 3 and 1 corners.

And so continue the work, after each circle raising the brick walls of the house along the entire perimeter by 1-2 rows until the masonry is completed. When forcing corners, you will inevitably have to make stepped cliffs, the so-called. fines.

Partly this will be due to the fact that you will have to use cut-down bricks - inlays, partly - to ensure a more durable connection between corners and walls in the future. For a future brick house, it is extremely important that the corners are straight and strictly vertical. The angle is checked with a square, brick should fit tightly against it. The verticality of the corners, especially above 7-8 rows, is controlled using a plumb line, and the horizontal - using a building level. Professionals take measurements every 4-5 rows, but if you do not have enough experience, do not be lazy to take them more often. Return to contents To give the brickwork strength, its longitudinal, transverse and vertical seams are tied.

In all schemes, not only whole bricks are used, but also inserts from quarters, halves and three-quarters. To make partial bricks, a pick-hammer is used. To make them, it is better to take bricks with defects. Such partial pieces are always laid with the broken edge inside the masonry, so that the whole side always faces outward of the wall.

Image 1. Laying right angles: a - walls of 2 bricks; b - walls of 2.5 bricks. Longitudinal seams are seams running along the horizontal. Their bandaging is necessary to evenly distribute the resulting stress across the entire width of the wall.

In addition, the dressing does not allow the brickwork to separate into even thinner layers. The dressing is performed in rows laid out across the main direction of the masonry. Such rows are called bonded rows and are laid at the rate of 1 bonded row per 4-5 rows of regular masonry, although other options are possible. Transverse and vertical joints are the seams between bricks inside the masonry. Their bandaging is done to give the brick wall solidity.

Bandaging of transverse seams is carried out mainly in spoon rows, in which the bricks are laid with the long side along the direction of the masonry with each newly laid row shifted by a quarter or half a brick in relation to the one already laid. But there are options for building a brick house in which bandaging of transverse seams is carried out in stitched rows. In practice, transverse sutures are most often ligated using both methods. Vertical seams are not tied separately; if the laying is done correctly, they are tied automatically. There are three main patterns for tying seams, differing in width: single-row (aka chain), three-row and multi-row. Since the corners of a brick house are driven out ahead of the laying of the walls, negligence or an error in performing the chosen dressing method in the corners almost always leads to the appearance of longitudinal, transverse or vertical - depending on the method of laying and the error made - cracks in the wall.

Image 2. Multi-row masonry of corners: a - walls 2 bricks thick; b - walls 2.5 bricks thick. Whatever suture dressing scheme is used, there is one general rule: the wall must begin and end with a row of studs. Therefore, given the importance of bonded rows for the quality and reliability of the wall, only whole bricks need to be taken for them. The strongest, but also the most labor-intensive, is considered to be single-row masonry, in which bonded and bonded rows alternate in shifts.

When using this masonry, a large number of three-quarter inserts are required, so only a sufficiently qualified mason can perform it. The corners are forced out according to this scheme as follows: the first row is laid out completely with whole bricks and ends with two three-quarter inserts, which will serve as the end of one wall and the beginning of another , the first row of which is joined to the laid one at a right angle (image 1: a - forcing into 2 bricks, b - into 2½ bricks). In the second row, the rows are swapped: the spoon is placed on the bonded row, and vice versa. In this way, the rows alternate until complete completion works With this dressing, it turns out that the laid out spoons of the corner of one wall become butt joints for the corner of the other, while two three-quarter spoon inserts become the end ones. In this dressing scheme, quarters and halves are not needed, but a large number of three-quarters are needed. Multi-row masonry is considered less labor-intensive compared to single-row masonry.

When using it, the walls are vertically limited by laying out three-quarters at the beginning of the first two rows. In the future, when forcing a house made of bricks, whole and incomplete bricks are alternated in rows of trays at the restrictions, while during laying the tray rows should overlap those laid below by half a brick. The forcing of corners begins with two three-quarters, extending like a spoon outside the adjacent wall. At the same time, between the butts and three-quarters form a gap, which is filled with quarters. When completing the second row, the bricks are swapped: the backfill is done with pokes, and the mile with spoons.

The next rows are forced out by tying the vertical seams (image 2: a - forcing into 1 brick, b - 1½ bricks, c - 2 bricks). Three-row masonry is a type of multi-row. Its peculiarity is that one row and three rows of spoons alternate. This is the only dressing scheme in which the vertical seams in all 3 spoon rows are allowed to coincide. A clear knowledge of what and how to do, correctly performed necessary calculations, as well as hard work and responsibility - these are the 4 pillars that will certainly lead you to success in such a difficult task as forcing out the corners of a brick house. Straight corners and smooth walls for you! Good luck!

When brick objects are built, regardless of its purpose and type, for example, a house or a fence, the question always arises regarding the correct laying of the corner.

It is how well the brickwork of the corners is done that determines the possibility of even laying of the wall itself, the strength and stability of the folded object.

Advice: If you are a novice mason, then before the actual work you should do a test, “dry” masonry, that is, without using mortar.
Otherwise, the cost of error will exceed the savings.

Preparing incomplete material

To bandage masonry seams in places such as vertical boundaries, junctions and intersections of walls. And of course, where brick laying is done at corners, incomplete bricks are needed.

This is one-quarter, half and three-quarters of the whole material. To obtain them, they usually use material that has broken corners or any other defects. This is done for the sake of economy.

One of the qualities of a mason is the ability to accurately determine and cut it correctly.

Otherwise, if such material has inaccurate dimensions, suture ligation will be disrupted and solution consumption will increase. All this will lead to a decrease in masonry.

The following figure shows how you can chop and hew brick, respectively, instructions for cutting brick with your own hands:

1. To correctly determine the length of an incomplete briquette, the hammer handle contains special notches that correspond to the length of the required parts.
2. The line along which the brick will be cut is marked with a hammer blade.
3. Then a notch is made by hitting the spoon with a hammer on both sides.
4. Then, with the help of a strong blow, the brick is cut along the marked line.

Attention: During the chopping process, the direction of the hammer when striking should be perpendicular to the spoon.
Otherwise, the resulting briquette will have an oblique end.

1. If it is necessary to cut lengthwise, first light blows are applied to all four planes, after which a strong and short blow is made along the cutting line.

Corner brickwork

Corner masonry is divided into two types, depending on the use of the dressing method.

Single row dressing

When a single-row dressing is used, when deciding how to lay out a brick corner, perform the following steps:

1. It is necessary to pass the masonry of the adjacent wall through the main wall and to the front side. It ends with three-quarter or splice material if fours or three-quarters are used.
2. In the next row, a row of the wall that is adjacent is laid to the spoons of the main wall.
3. The following actions are performed alternately.

Multi-row dressing

The steps are as follows:

1. The first row is laid out in the same way as the actions were carried out during single-row dressing, although only if the thickness of the walls is calculated in whole bricks. Attention is drawn to the fact that the backfill of the second row is laid out with bricks, and the inner and outer versts with spoons.
   If , then the pokes of the first row are laid out outside the facade, and the pokes of the second row look inside the room, which means that the spoons are accordingly located outward.
2. Further, the third and up to the sixth row are laid out only with spoons. And at the same time, the vertical transverse seams are ligated either by a quarter or half of the briquette.
3. After the sixth row is laid, the cycle is repeated, starting from the first point.

Advice: If the load on the wall is small, then in the areas where the windows are located, the backfill can be filled with either halves or broken bricks.
Brick corner tiles can also be used.

Some nuances of corner masonry

It must be said that the vertical limitation is set in the first two rows, laid out by three-fours, starting both the first and second row. For the remaining spoon rows, the restrictions alternate. From them, an incomplete brick is placed with a spoon with a whole one, while the spoons should overlap half the brick.

A right angle is laid out using quarter and three-quarter bricks. The corner begins with two three-quarter corners, with each of them placed with a spoon in the direction of the outer mile of the corresponding wall. Between the bonded and three-quarter briquettes, the gap that appears is filled with quarter briquettes.

The filling of the next row is usually done with pokes, and the versts with spoons. After this, the vertical seams are ligated using spoon rows.

If the inner wall is connected to the outer wall using double sand-lime brick M 150, then such a connection is made as a single-row or multi-row fine. Therefore, a steel mesh is laid every meter or one and a half.

It must be remembered that corner masonry (no matter what kind of building brick was used) must be vertical. To check verticality, it is worth using a plumb line, since it shows the vertical better than the building level. Otherwise, the corner may be blocked and, if there is a heavy load, the entire wall may fall on its side.

For the same thing, it is possible to use a straight metal corner, which is attached with the lower part to at least five masonry rows. And then vertical alignment will take you much less time.

Conclusion

Corner masonry should be treated very responsibly, because its implementation determines how smooth, beautiful and stable your walls will be. In the video presented in this article you will find additional information on this topic.

Preparation of partial bricks. To bandage the masonry seams of vertical restrictions, places of abutment and intersection of walls, when laying pillars and piers, incomplete bricks are required: quarters, halves and three-quarters. They are prepared by masons. For quarters, three-quarters and halves, in order to save money, it is necessary to use bricks with broken corners or other defects.

Every mason should be able to accurately determine the size of an incomplete brick and cut it correctly. This is necessary because if the dimensions of incomplete bricks are inaccurate, the ligation of the seams is disrupted, the consumption of mortar increases, and this reduces the strength of the masonry.

To correctly measure the length of an incomplete brick, notches are made on the handle of the hammer corresponding to the lengths of the brick parts. The brick cutting line is marked with a hammer blade. Then they make a notch with a hammer blow, first on the spoon of one side, then on the spoon of the other side, and finally, with a strong blow, they cut the brick along the marked line.

When cutting bricks, the hammer blow must be directed perpendicular to the spoon, otherwise the cutting line may be incorrect and you will end up with an incomplete brick with an oblique end. If a brick needs to be split lengthwise, then first light blows are applied to its four planes, and then with a strong and short blow along the stub line at the end of the brick, they split it into the required parts. Brick is also cut with the edge of a trowel.

General rules for laying walls. Laying begins with securing the corner and intermediate orders. They are installed along the perimeter of the walls and verified by plumb line and level or level so that the notches for each row in all orders are in the same horizontal plane.

Orders are placed at corners, at intersections and junctions of walls, as well as on straight sections of walls at a distance of 10...15 m from each other.

After fixing and checking the orders, the beacons are laid out in the form of a refuge fine, placing them at the corners and on the border of the site being built.

Then mooring lines are moored to the formations. When laying external versts, a mooring cord is installed for each row, pulling it at the level of the top of the laid row with a distance of 3...4 mm from the vertical plane of the masonry. The mooring cord for lighthouses can also be strengthened with the help of a mooring bracket, the sharp end of which is inserted into the masonry seam, and the mooring is tied to the blunt, longer end, resting on the lighthouse brick. The free part of the cord is wound around the handle of the staple. By turning the staple to a new position, the mooring cord is tightened for the next row. To prevent the mooring cord from sagging between the beacons, a wooden lighthouse wedge is placed under the cord, the thickness of which is equal to the height of the row of masonry, and a brick is placed on top of it, with which the cord is pressed. Lighthouse wedges are laid every 4...5 m with a projection beyond the vertical plane of the wall by 3...4 mm. The mooring cord can also be strengthened by tying it to nails secured in the joints of the masonry.

After the orders have been established, the beacons have been laid out and the mooring cords have been pulled, the masonry process is carried out in the following sequence: lay out the bricks on the wall, spread the mortar under the outer mile and lay the outer mile. Further operations depend on the accepted masonry order: row, stepped or mixed.

During the laying process, observe the following general rules.

Walls and piers are made using a single suture dressing system - multi-row or single-row (chain). For laying pillars, as well as narrow partitions (up to 1 m wide) inside a building or hidden by finishing, a three-row seam dressing system is used.

The bonded rows in the masonry are laid from whole bricks. Regardless of the adopted system for dressing seams, bonded rows must be laid in the lower (first) and upper (last) rows of erected structures, at the level of the edges of walls and pillars, in protruding rows of masonry (cornices, belts, etc.).

When bandaging seams in multiple rows, be sure to lay bonded rows under the supporting parts of purlins, floor slabs, balconies, under mauerlats and other structures. With single-row (chain) ligation of seams, it is allowed to support prefabricated structures on spoon rows of masonry.

The use of brick halves is allowed only in the laying of backfill rows and lightly loaded stone structures (sections of walls under windows, etc.).

Horizontal and transverse vertical joints of masonry walls, as well as all joints (horizontal, transverse and longitudinal vertical) in lintels, piers and pillars must be filled with mortar, with the exception of joints when laying hollow areas.

Three-quarter bricks and other incomplete bricks are laid with the broken side inside the masonry, and the whole side facing out.

When single-row (chain) ligation of straight walls having an odd number of half-bricks in thickness, for example one and a half, the first outer mile of the first row is laid with butt bricks, and the second with spoon bricks. When laying walls that have an even number of half-bricks in thickness, for example two, the first row begins with laying dowels along the entire width of the wall; in the second row, mile bricks are laid with spoons, backfill - with butts. When laying thicker walls in verst rows, spoons are placed above the studs in the second row, and studs are placed above the studs. Zabutka in all rows is performed with pokes.

Vertical limitation (an even edge of the wall along a vertical plane) when laying with a single-row ligation system is obtained by first laying three-quarter walls. When building a wall of 1/2 brick, halves are placed at the beginning of it, one row at a time. To lay the vertical limit of a wall of 1 brick, two three-quarter blocks are placed in the longitudinal direction at the beginning of the stretcher row, and a whole brick, as usual, in the stud row.

In the vertical boundary of the wall, one and a half bricks are placed in the stud row at the beginning of the wall in the corners, three quarters are placed in the transverse direction, in the tray - three three-quarters are placed in the longitudinal direction of the wall.

Laying wall corners is the most important work and is performed by qualified masons.

Right angles with a single-row system are laid out in the following sequence: the first butt row of each right-angle wall begins from the outer surface with two three-quarters. The second row of the outer verst is put in with spoons. To ensure that the seams are bandaged, quarters of bricks are laid in the backfill in the inner verst.

In the first row, the masonry of the adjacent wall is passed through the main wall to its front surface and finished with pokes and three-quarters, if three-quarters and fours are used to maintain the dressing, or the skipped masonry is finished with only three-quarters. In the second row, a row of adjacent wall joins the main wall spoons.

The intersection of walls with a chain ligation system is performed alternately by passing rows of masonry of one wall through another.

When laying walls with multi-row ligation, the first row is performed in the same way as with single-row ligation with butts. If the thickness of the wall is a multiple of a whole brick, in the second row the outer and inner versts are laid out with spoons, and the backfill with pokes. If the wall thickness is a multiple of an odd number of bricks, the first row is laid out with pokes on the facade, and with spoons inside the room; the second row, on the contrary, with spoons on the front, and pokes inward. The subsequent 3...6th rows are erected only with spoons with ligation of the vertical transverse seams into half or a quarter of the brick.

When laying lightly loaded areas under windows, when filling frame walls It is allowed to use polovnyak and broken bricks in the backfill.

The vertical limitation of the wall is obtained by laying out the first two rows with three-quarters at the beginning. In the remaining rows of trays, incomplete bricks at the restrictions alternate with whole ones. The bricks are placed so that the spoons overlap each other by half a brick.

Right angles are laid out using three-quarters or quarters. The laying begins with two three-quarter blocks, each of which is placed with a spoon in the outer verst of the corresponding mating wall. The gap formed between three-quarter bricks and interlocking bricks is filled with quarter bricks (see the first row of masonry). In the second row, versts are done with spoons, and backfilling is done with pokes. The next rows of spoons are laid with ligation of the vertical seams.

When crossing walls, the butt rows of one wall are moved a quarter of a brick away from the face of the other wall and quarters are laid in this gap. With subsequent spoon rows, the bonded rows of both intersecting walls are tied into 1/4 or 1/2 bricks. In this case, when intersecting the rows of spoons, the intersecting walls do not seem to pass through the main wall, but only go deeper into it by 1/2 brick.

The junctions of the walls are carried out in the same way as when laying the intersection of walls.

When walls are not erected at the same time, they can be connected in the form of vertical multi-row or single-row fines. In these cases, three steel rods with a diameter of 8 mm are laid in the external walls, which are placed three rods in a row at least 2 m apart along the height of the masonry, as well as at the level of each floor. The rods must have a length of at least 1 m from the junction angle and end with an anchor.

Often the masonry of external walls is 138 mm, and the masonry of internal walls is made of ceramic bricks 65 mm thick or brick (stones) 138 mm thick, and the masonry of internal walls is made of thickened bricks 88 mm thick. In this case, the junction of the internal walls with the external ones is tied every three rows of bricks with a thickness of 88 mm.

Thin, 1/2 brick or 1 brick, walls inside buildings are erected after the outside ones. To do this, a groove 1/2 brick deep is made in the outer wall and a thin wall is inserted into it. There is another way of pairing, when the seams outer wall During the masonry process, reinforcement bars are laid.

Laying wall projections. Wall projections (pilasters) are laid out using a single-row or multi-row ligation system if the pilaster width is 4 bricks or more, and if the pilaster width is up to 3 1/2 bricks - using a three-row ligation system.

To connect the ledge with the main wall, depending on the size of the pilaster, partial or whole bricks are used, using the brick laying techniques recommended for tying the junctions (intersections) of walls.

Laying walls with niches. Walls with niches are laid out using the same dressing systems as solid sections. In this case, niches (for heating appliances) are formed, interrupting the internal mile, and incomplete and interlocking bricks are laid in the corners of the niche to connect them with the wall.

Laying walls with channels. Gas ducts, ventilation and other ducts are placed, as a rule, in the internal walls of the building: in walls 38 cm thick - in one row, in walls 64 cm thick - in two rows. The cross-section of the ducts is usually 140x140 mm (1/2x 1/2 brick), the smoke ducts of large stoves and stoves are 270X140 mm (1/2x 1/2 brick) or 270x270 mm (1x1 brick).

Gas and ventilation ducts in walls made of brick, solid and hollow concrete stones are laid out from ceramic solid bricks with appropriate ligation of the channel masonry with the wall masonry. The thickness of the walls of the channels and partitions (cuts) between them is at least 1/2 brick.

The channels are made vertical. Channel bends are allowed at a distance of no more than 1 m at an angle of at least 60° to the horizontal. The cross-section of the channel in the withdrawal section, measured perpendicular to the axis of the channel, must be the same as the cross-section of the vertical channel. Sloping areas are laid out from bricks hewn at a certain angle, the remaining areas are made from whole bricks.

For laying channels, the same solutions are used as for the internal walls of the building. In low-rise buildings, chimneys are laid on clay-sand mortar.

In places where wooden structures (floor beams, mauerlats) come close to smoke ducts (chimneys), cut fireproof materials (brick, asbestos) and increase the thickness of the duct walls. The same cutting is done in places where the structures are close to the ventilation ducts running next to the smoke ducts. The gaps between the wooden structures of the building and the smoke duct, i.e., the inner surface of the flue, must be at least 38 cm if the structures are not protected from fire, and at least 25 cm if they are protected.

Sections of brick walls with channels are laid out with preliminary markings on the wall according to a template - a board with cutouts corresponding to the location and size of the channels on the wall. The same template is used to check the correct placement of the channels during the masonry process.

When laying, inventory buoys in the form of hollow boxes made of boards or other material are inserted into the channels. The cross-section of the buoy is equal to the dimensions of the channel, and its height is 8...10 rows of masonry. The use of buoys provides correct form channels and protects them from clogging, while the seams are filled more completely. The buoys are rearranged every 6...7 rows of masonry.

The seams of the canals must be well filled with mortar. As the laying proceeds, they are rubbed down with a mop when rearranging the buoys. Wetting the surfaces of the channels with water, rub the solution with a mop and smooth the seams, eliminating roughness where soot can settle.

After finishing the masonry, the channels are checked by passing a ball with a diameter of 80...100 mm, tied on a cord, through them. The location of the channel blockage is determined by the length of the cord with the ball lowered into it.

Laying wall corners- the most responsible work, and it is performed by highly qualified masons. Right angles are laid out according to two patterns. The sequence of masonry according to the first scheme is shown in Fig. 39, a...g. According to the second scheme, the first butt row of one of the walls forming a right angle starts from the outer surface of the second wall and ends towards the first row of the first wall. In the second row, the masonry proceeds in the reverse order, i.e., the masonry of the second row of the second wall begins from the outer surface of the first wall in three-quarters. As a result, the spoon rows of one wall protrude onto the front surface of the other wall.

Rice. 39. Chain ligation system for laying right angles and limiting walls with a quarter:
a - 1 brick thick, b - 1 1/2 bricks, c - 2 bricks, d - 2 1/2 bricks

The wall, which is passed to the front surface of another wall, must end with three-quarters arranged longitudinally: the outer spoon rows are passed through, the outer butt rows are adjacent. With this brick layout scheme, the corners are laid out without quarters, but with a significantly larger number of three-quarters.

Rice. 40. Chain ligation system at the junction (a, b) and intersection (c) of walls:
a - brick thickness, 6 - 2 bricks

The junction of the walls is done as follows (Fig. 40, a, b). In the first row, the masonry of the adjacent wall is passed through the main wall to its front surface and finished with pokes and three-quarters, if three-quarters and fours are used to maintain the dressing (see Fig. 40, a), or the skipped masonry is finished with only three-quarters (see Fig. 40 , b). In the second row, a row of adjacent wall joins the main wall spoons.

The intersection of walls (Fig. 40, c) is performed by alternately passing rows of masonry of one wall through another.

Rice. 41. Multi-row dressing system when laying walls with thickness:
a - 1 brick, b - 1 1/2 bricks, c - 2 bricks

Rice. 41. Continued:
e - 2 1/2 bricks

With multi-row dressing, the first row is laid out in the same way as with single-row dressing, with pokes. When the wall thickness is a multiple of a whole brick (Fig. 41, a, c), in the second row the outer and inner versts are laid out with spoons, and the backfill with pokes. With a wall thickness that is a multiple of an odd number of bricks (Fig. 41, b, d), the first row should be pointed at the façade and placed with spoons inside the room; the second row, on the contrary, with spoons on the front, and pokes inward; the next 3...6th rows - only with spoons with ligation of the vertical transverse seams into half or a quarter of the brick.

When laying lightly loaded walls in areas under windows, as well as when filling frame walls, it is allowed to use half-fill in the backfill.

The vertical limitation of the wall is obtained by laying out the first two rows using three-quarter blocks at the beginning of the first and second rows. In the remaining rows of spoons, incomplete bricks at the restrictions are alternated with whole ones, the bricks are laid out so that the spoons overlap each other by bricks. Examples of dressings in places of restrictions are shown in Fig. 41, a...g.

Right angles with a multi-row dressing system (see Fig. 43) are laid out using three-quarters and quarters. The laying of the corner begins with two three-quarters, each of which is placed with a spoon in the outer verst of the corresponding mating wall. The gap formed between three-quarter bricks and interlocking bricks is filled with quarter bricks (see 1st row of masonry). In the second row, versts are done with spoons, and backfilling is done with pokes. The laying of the next rows of spoons is carried out with ligation of the vertical seams (see Fig. 41, a... d).

Rice. 42. Multi-row dressing system when crossing walls 2 and 1 1/2 brick thick with a wall 2 brick thick

The intersection of walls (Fig. 42) is laid out as follows: the butt rows of one wall are moved 1/4 of a brick away from the face of the other wall, and quarters are laid in this gap. With subsequent spoon rows, the bonded rows of both intersecting walls are tied into 1/4 or 1/2 bricks. In this case, when intersecting the rows of spoons, the intersecting walls do not seem to pass through the main wall, but only go deeper into it by 1/2 of a brick.

The joining of walls is carried out in the same way as when laying the intersection of walls.

The connection of internal walls to external ones, if they are not erected simultaneously, can be done in the form of a vertical multi- or single-row fine (see Fig. 11). In these cases, the steel ties laid in the outer walls to strengthen the masonry (rods with a diameter of 8 mm) are placed at least 2 m apart along the height of the masonry, as well as at the level of each floor. The rods have a length of at least 1 m from the junction angle and end with an anchor.

Often the outer walls are made of 65 mm thick ceramic bricks or 138 mm thick stones, and the internal walls are made of thickened bricks 88 mm thick. In this case, the junction of the internal walls with the external ones is tied every three rows of bricks with a thickness of 88 mm. Internal walls 1/2 brick thick or 1 brick is placed after the external capital ones. To attach them to the main wall, a groove is made in it, into which a thin wall is inserted. If there are no special instructions in the project, the groove is made 1/2 brick deep. Another connection method is that the groove is not left, but reinforcement bars are placed in the seams of the main wall during the masonry process to connect with the adjacent walls.

Laying bricks in two bricks requires qualifications that allow you to build strong and durable structures. In addition to choosing high-quality building materials, attention is paid to the preparation of masonry mortar, observing the order of their addition during the mixing process.

Characteristics of building bricks

Brick, as a rule, is made in the shape of a regular parallelepiped, has 6 flat faces, each pair of which has its own name: pokes, spoons, beds. When constructing permanent structures, single brick (65 mm high) or thickened brick (88 mm high) is most often used.

There are no uniform dimensional standards for piece building materials, since they specifications change in accordance with the climatic and operational conditions of the facility location capital construction.

Laying of two bricks is carried out in horizontal rows according to a pattern, the choice of which depends on the dimensional parameters of the product, the purpose of the building, as well as the design load and thermophysical factors. The thickness of the masonry is determined by the combination of dimensional parameters of the brick and the layer of fastening mortar.

Design height of the structure

Knowing the dimensional parameters of piece masonry material, you can calculate the final dimensions of the building:

At making the right choice ligation schemes: laying bricks in two bricks allows you to create a permanent structure. Ligation of vertical seams is carried out in the transverse or longitudinal direction.

When transversely ligating vertical seams, spoon rows are alternated with bonded rows, with masonry elements shifted by their dimensional half. Technological method masonry allows you to distribute the dynamic loads of the structure and reduce the risks of thermal deformation of the monolith.

The ligation of longitudinal vertical seams is carried out using the method of laying butt rows, which makes it possible to protect the structure from destruction. It should be taken into account that the thickness of the brickwork of 2 bricks exerts significant pressure on the soil, therefore it is necessary to place a reinforced foundation under the building.

Bricklaying

Piece masonry building material produced at cement mortar bed or spoon.
The thickness of the masonry should correspond to an odd (even) multiple of ½ of the brick. To secure the structure, ligation of sutures can be used:

• single-row (chain);
• three-row;
• multi-row.

Single-row dressing is carried out by sequentially alternating the spoon and butt rows. The three-row ligation method is used in the construction of columns, pillars or piers, the thickness of which is no more than 1,000 mm. In a multi-row scheme, the spoon row is tied with a tying row and repeated after 6 rows of masonry.

Installation methods

Installation of external and internal versts can be carried out in one of three ways:

• end-to-end (the brick is laid directly on the mortar);
• end-to-end with figured trimming of masonry mortar;
• pressing (laying on a tight solution).

Mortar cutting is the operation of jointing triangular, concave, convex, rectangular or rounded shapes. The backfill is laid half-butt.

The choice of bricklaying method depends on the requirements for appearance front side, time of year, moisture level of the material, plasticity of the cement-sand mortar.

Learning to work with piece-type building materials is quite simple. Through the Internet, you can get lessons on laying bricks in two bricks using videos posted on construction sites.

The working process

Brick laying in two bricks is carried out using a technology that provides waterproofing of the basement part of the building. A layer of insulating material is installed under the brick along the perimeter of the masonry. After forcing out several rows of masonry, rows with divisions are secured with staples at the corners of the structure.

Moorings are attached to the rows, allowing the masonry to be oriented horizontally and vertically. A layer of masonry mortar is applied to the previous row with a trowel, and the new brick is laid using the “press” or “butt” method. When working on site, you must have auxiliary equipment and scaffolding.

When working, the following rules must be observed:

1. First-order masonry should be done only horizontally or perpendicular to the compression force;
2. The masonry of the first and second order must be perpendicular to the plane of the first order, as well as to each other;
3. The load from the top brick should be distributed between the two lower masonry elements.
