Turnkey cottage construction calculator. Calculation of materials for building a house made of bricks and aerated concrete, with a monolithic slab foundation, timber-beam floors, ondulin roofing

Let's say you decide to build a house with your own hands. However, before starting construction, it is imperative to calculate the amount of building material. Currently, building bricks are quite expensive, accurate calculation will significantly reduce your costs.

A preliminary calculation is necessary in order to be able to purchase material from one batch. This will avoid the trouble of having a different shade in different batches.

Note! The use of building material of different batches will not have the best effect on the appearance of your building. This is due to the fact that it is almost impossible to produce fake diamond from clay of the same color in different batches, since both the composition of the clay and the firing temperature may slightly differ.

Below is a table by which you can see the correspondence of these parameters.

Table 1

Calculation procedure

Stages

The following steps should be followed:

• To correctly calculate the number of bricks per house, you need to know its dimensions, such as length, width and height.

• After calculating the perimeter of the building, the resulting number is multiplied by the height. As a result, we get the area of ​​the surface to be erected.
• Next, you need to calculate the area of ​​the window and doorways, subtract the resulting number from the total area.

You also need to decide on the choice of this or that type of stone, which happens:

• Single. Has dimensions 65 x 120 and 250 mm;

• ... Has dimensions of 88 x 120 and 250 mm;

• Double. Has dimensions 138 x 120 and 250 mm.

Using one-and-a-half or double silicate brick M 150, walls can be erected much faster, you just need to know that this can worsen the appearance of the building. The price of a double and one and a half is certainly higher than the price of a single. Many people think that a single looks much more beautiful, but the idea of ​​beauty is a rather controversial issue.

To make a more accurate calculation, it is necessary to add to the height of each stone 10 mm... This is exactly how much the thickness of the seam is. You should also add something like 5% for the battle.

table 2

Note! The data on the quantity in table 2 are indicated without taking into account door and window openings, the dimensions of which are individual.

This instruction will allow everyone to understand how to calculate the number of bricks on their own. There is nothing complicated about it.

A simple example

An example of calculating the material for the construction of a house 12 by 12 m, having 2 floors:

• Determine the perimeter of the house. We add up its length and width. We get: 12 + 12 + 12 + 12 = 48 m;

• We count the area. To do this, multiply the perimeter by the height. Let's say that the height of each floor of our house is 3m, total height 3 + 3 = 6 m. As a result, the area will be 48 * 6 = 288 m 2 ;
• Further steps depend on what kind of laying you will perform. Let's say we are laying 2 stones and facing 0.5 stones. According to table 1, we see that the wall thickness in this case will be 640 mm. According to table 2, we see that in this case there are 204 pieces per 1 m 2 ;

Gas silicate wall with brick facade

Gas silicate masonry

According to the characteristics of heat saving, acoustic protection, fire resistance, autoclaved gas silicate significantly outperforms ordinary brick.

Compared to other concrete building materials, autoclaved aerated concrete blocks have an increased and uniform structure of micropores throughout the volume, which explains their unsurpassed heat-shielding parameters, as well as "breathing" ability.

Despite the fact that aerated concrete blocks are being promoted as a very easy-to-use and heat-efficient structural material, their use is advisable only if the purchase of extremely high-quality material is guaranteed: Beston, Wehrhahn, Hess, Hebel, Ytong and serious adherence to the manufacturer's specifications, it is better with the involvement of specialists ...

Currently, blocks of autoclaved aerated concrete (Ytong®, Wehrhahn®, Hebel®, Hess®, Beston®) are sold on the construction market with small dimensional deviations (in the range of ± 1 mm), which can be laid on special masonry glue.

A wall folded in this way is characterized by minimal thermal conductivity, due to the fact that there are no “cold zones” formed by inter-brick joints made of sand-cement mortar, and, in addition, the installation costs of gas silicate blocks are reduced by an average of one third.

Adhesive for aerated concrete is sold at a price twice the cost of a simple cement binder, with almost five times less consumption.

According to existing norms, for the central region of the country there is enough outer wall from aerated concrete blocks with a cross section of 0.40 m.

External finishing of aerated concrete walls should not block the diffusion of moisture from the house to the outside. Therefore, it is unacceptable to paint walls made of aerated concrete with “non-breathing” means, to cover with foam plastic, to plaster with cement-sand plaster.

When installing gas silicate walls, it is necessary to combine a lot of recommendations and building subtleties, otherwise, instead of saving on insulation, you can get damp, too cold, or unsafe walls.

• According to the technology, it is necessary to lay with reinforcing rods the places under the windowsill and the places of support of the jumpers, as well as every 4-5 rows of blocks.
• The installation of the first row of aerated concrete blocks should be taken especially carefully, checking the horizontal and verticality of the wall against the level during the installation process.
• In order to install reinforcing rods, grooves are made along the top of the wall with a groove cutter in thickness and depth of 30 * 30 mm, which, when laying the reinforcement, are rubbed with an adhesive for aerated concrete.
• Gas silicate blocks can be planed, drilled, gouged, sawed with a hacksaw, milled directly at the construction site.
• Uneven or excessively bulging aerated concrete block you need to adjust the plane to the required level at the place of installation.
• On the last row of aerated concrete blocks, in the board formwork preparation, a reinforced-reinforced mortar belt, 20 cm thick, is performed. On the outer surface, the mortar belt is insulated with a 50-mm layer of extruded expanded polystyrene.

Face brick cladding

Brick is obviously the most famous construction material for the construction of a house, which, in addition to the classic appearance, is distinguished by a large (up to a hundred freeze-thaw periods) frost resistance and low (no more than 6%) water absorption, which sets the long life of stone households. Among the facing brick products, in addition to standard ones, there are glazed, figured and clinker bricks.

The combination of a layer of facing-brick masonry and autoclaved aerated concrete in the composition of the facade gives a rather harmonious building structure which links classic style and modern advances in the field of heat-efficient materials.

Nowadays it is produced facing brick various reliefs (grooved, chipped, smooth, rough) and profiles (wedge-shaped, rounded, beveled, rectangular), as well as colors (from white-yellow to terracotta), which helps to realize any original artistic ideas.

• Since there is a possibility of the formation of deformation cracks, you should not tie the front and aerated concrete masonry with inflexible metal rods embedded in the seams of the masonry.
• The coupling of the front and aerated concrete walls is done by laying five brick rows, using a plaster mesh, while maintaining an air gap through the intervals of the reinforcement.
• The front wall is placed in 1/2-brick on a cement-sand binder, with laying, after 4 rows of spoons, butt row;
• The main gas silicate wall is separated from the facing brick by a gap of up to 50 mm (along the entire height of the floor) for steam removal, leaving the inlet / outlet channels in the upper and lower rows of the facing masonry.

Reinforced concrete slab and monolithic tape foundation

A solid-slab foundation is made along the boundaries of the house in the form of a single reinforced concrete slab and is practiced in a buried or not buried version.

In the deepening version, the concrete slab acts as the base on which the lateral parts of the foundation are built, which define the underground floor. At high level groundwater, it is better to erect the vertical parts of the foundation by the method of continuous concreting, using waterproofing measures: coating, impregnation, pasting.

Above ground slab foundation is used in low-rise buildings, with unstable soils: peat bogs, reclaimed, bulk or heavily weathered, as well as in waterlogged areas. This foundation is advisable when building garden structures that do not require a high basement part of the foundation and basement.

From experience, when the top foundation slab serves as a blank for the floor covering of the 1st floor, and monolithic slab installed above the depth of soil freezing, there is a need for heat protection of the soil under the base plate and under the blind area.

The best solution would be to install a heat shield made of extruded polystyrene foam, such as Teplex, Polispen, Primaplex, Ursa XPS, Styrodur, Penoplex, Styrofoam, Technoplex, because other heat-shielding materials (expanded clay granules, granular foam, glass wool) soon become saturated with moisture, which leads to a rapid decrease in their heat-shielding characteristics in wet soil.

A short technique for laying a slab foundation with vertical parts in the form of an unbreakable concrete ring:

• The first step is to remove the land to the level specified by the project.
• A crushed stone preparation, fractions of 40-60 mm, 20 cm thick, is poured onto the prepared substrate and compacted tightly.
• Cement-sand filling is carried out, up to 5 cm thick.
• A waterproof membrane is laid out with an outlet along the border of 2000 mm, for the purpose of vertical waterproofing of the vertical part of the foundation.
• In order to protect the waterproofing material from possible damage during the installation of the reinforcement structure, a repeated layer of cement mortar, 4-5 cm high, is applied to the moisture insulation, along the perimeter of which formwork boards are mounted along the height of the foundation slab.
• The formed plate is pulled together from the inside with two nets made of welded steel rods with a section of Ø14, type AII (A300), AIII (A400) with 20x20 cm cells.
• For a solid-slab foundation, only high-quality concrete mix, grade M300, class B22.5, is used, supplied by an automatic mixer.
• With an indentation of up to 25 cm from the edges of the slab part of the foundation, the formwork is mounted to the height of the side parts in the form of an unbreakable reinforced concrete ring,
• A reinforcing belt consisting of iron rods number A300 d10-d14 is placed in the completed mold for pouring, and concrete is made.
• The setting time of concrete (when to do the stripping) is, in practice, 4 weeks in a warm season.

Overlap made of wood beams

Timber beams are mainly popular in private construction, due to the convenience and low cost of their installation.

For beam floor traditionally used sawn timber of coniferous trees (spruce, larch, pine), with a volumetric moisture content of no more than 12-14%. The best beam is a bar with an aspect ratio of seven to five, for example, 14x10 cm.

When designing a beam structure, it is necessary to be guided by special diagrams that determine the dependence of the beam geometry on the span size between supporting structures and the weight of the cargo; in another way, it is permissible to start from the approximate rule that the height of the beam should be about 0.042 of the floor length, and the thickness - 5 ÷ 10 cm, with a load of 150 kgf / m2 and a laying step of 50-100 cm.

For a possible replacement of the lag of the calculated size, bolted boards should be used, with the obligatory preservation of the overall size.

Typical installation points for timber beams:

• The installation of the beam beams is carried out in following sequence: first and foremost, the first and last, and then, with level adjustment, all the rest. Beams should be installed on the wall no shorter than 15-20 cm.
• The beams are set aside from the wall at least 5 cm, and the gap between the beams and the smoke channel must be at least 40 cm.
• in log cabins, the edges of the girder beams are sawn in the manner of a bell, and then they are driven into the finished cut of the upper crown to the entire depth of the wall.
• To protect against possible rotting, which occurs from moisture in the brick environment, the ends of the beams are cut at an angle of about 60 degrees, treated with an anti-rotting solution (for example: Kartotsid, Aquatex, KSD, Dulux, Senezh, Holzplast, Biofa, Tex, Biosept, Pinotex, Cofadex , Tikkurila, Teknos) and wrapped with roofing felt, keeping the end edge open.
• Traditionally, in block-brick walls, the end parts of the beams are located in the niches of the walls, where condensation appears, for this reason, between the ends of the log and the brick, a vent is left for ventilation, and with a sufficient depth of the niche, an additional layer of thermal insulation is placed.

The covering of the last floor is thermally insulated with a vapor barrier membrane at the bottom of the thermal protection, the interfloor floor is not subject to insulation, and the basement floor is thermally insulated with the installation of a vapor barrier film over the insulation.

However, if the question of the structural strength of timber-beam floor slabs in practice, it is solved due to the obvious addition of the size of the beams and their number, then the situation with anti-noise insulation and fire protection is not so simple.

A possible technique for improving the acoustic and fire-prevention parameters of bar interfloor floors is as follows:

• To the base of the beam beams, at an angle of 90 degrees, on damping brackets, after 300-400 mm, metal guides are mounted - a crate, on which gypsum boards are suspended from below.
• On top of the lattice structure, synthetic fabric is spread and braced to the beams, on which mineral fiber plates, such as: Ursa, Izomin, Rockwool, Knauf, Izorok, Isover, 50 mm thick, with a rise on the vertical sides of the floor beams, are placed.
• In the rooms of the upper level, plywood slabs (1.6 ... 2.5 cm) are mounted on the beams, then, a hard basalt fiber sound insulator (25 ... 30 mm), and again, chipboard slabs are laid out for floor preparation.

Euro slate roof

Euroslate (otherwise called: ondulin, bituminous slate, bituminized slate, soft slate, ondulin slate), is a wavy mineral fiber base, fixed with a distilled bitumen compound and painted over with a mineral pigment that is resistant to UV radiation. bituminous corrugated sheet is made with different names: Guttanit, Ondura, Corrubit, Aqualine, Bituwell, Onduline, Nuline. Usual sheet sizes: 200x95 cm, weight 6 kg / sheet.

Roofing material installed on a supporting base made of rafter beams and a lathing layer.

In the construction of private buildings, a construction of 2.3 spans with inclined rafter beams and internal load-bearing walls is often used.

The interval between the rafter beams is usually in the range of 0.60 ... 0.90 m with a rafter section of 5x15 ... 10x15 cm; the lower sections of the rafter beams are lowered onto a fixing bar measuring 10x10 ... 15x15 cm.

The main qualities of a euro-slate roof are low cost and ease of assembly. Among the tangible shortcomings, one can cite a rather rapid loss of color juiciness, as well as a noticeable flammability of the cardboard-bitumen canvas, in comparison with a metal-tile roof.

Basic principles for installing a bituminous roof:

• The inter-row overlap of soft slate canvases and the gap between the battens are determined by the slope of the roof: if the latter is more than 15 °, then the overlap is 17 cm, and the distance between the battens is 0.30 ... 0.35 meters.
• In order to protect the sheets of bituminous slate from wrapping in gusts of wind, their fastening must be carried out from the lower zone of the end part of the roof, opposite to the prevailing direction of the wind.
• In order to prevent unnecessary layering at the intersections of 4 touching canvases, which contributes to the formation of cracks, the overlying layer is laid out from the middle of the first sheet of the underlying level.
• Euro-slate sheets are fastened along the bottom line in each upper half-wave, along the two middle battens - with a wave skip, and the upper edge is covered with an overlap of an overlying corrugated sheet or a ridge detail. To fix each sheet, about twenty roofing nails are enough: size -73.5, Ø3.0 mm or self-tapping screws (length -65.0, Ø5.5 mm) with neoprene washers.
• Ordinary overlap of corrugated sheets must be performed in 1 wave, however, with a roof slope of less than 10 degrees. - in two waves.
• Strengthening of the ridge parts is carried out in the direction of the masonry of bituminous slate canvases, with an overlap of 20 cm, with self-tapping screws in each top of the wave of the underlying corrugated canvas.
• To protect and decorate the end zones of the roof, wind profiles are used, the installation of which is performed from the above-cornice corner, with an overlap of 0.2 m.

Aerated concrete block masonry with a brick facade and internal thermal insulation

Foam concrete block masonry

Nowadays, foam concrete is very popular, economical and safe for health. wall material, which, in comparison with other brick blocks, has increased vapor permeability and microporosity.

According to existing standards, for the middle area, a single-layer outer wall made of foam concrete with a cross-section of 0.40 m with an outer glass wool thermal protection, a layer of 50 mm, is sufficient.

Puttying masonry from foam concrete blocks should be done only after 6-9 months (and sometimes even after a year), due to the strong shrinkage of foamed concrete - up to 3 mm per meter of masonry and the inevitable cracking of the plaster, for this reason, for prompt interior finishing of foam blocks houses, the use of plasterboard or gypsum fiber false panels is acceptable.

Soundproofing, fire protection, energy efficiency indicators foam concrete block overtakes ceramic bricks many times over.

The facade cladding of foam block walls should not block the movement of water vapor from the house to the street. In this regard, it is undesirable to trim foam block walls with foam plates, plaster with sand-cement mortar, paint with film-forming compounds.

Due to problems in the manufacturing process, foam concrete blocks (in comparison with gas silicate blocks), are usually not produced with sufficient accuracy, as a result of which they fit into an ordinary building mixture. In turn, the presence of significant joints of the mortar mixture between foam concrete blocks, along with an increase in material costs, contributes to the formation of "bridges" of cold and deterioration of the thermal insulation parameters of the wall.

When installing foam block walls, it is important to consider big number technological issues and requirements, otherwise, instead of reducing the cost of thermal insulation, it is realistic to get very cold, wet, or just cracked walls.

• It is necessary to approach the installation of the lower row of foam concrete blocks as seriously as possible, controlling the verticality and horizontalness of the masonry by the spirit level during operation.
• An uneven or slightly protruding foam concrete block must be hung to the required size at the place of installation.
• For the installation of reinforcing bars, grooves are made on the surface of the blocks with a circular saw in depth and width of 30 * 30 mm, which, when installing the reinforcement, are filled with an adhesive solution for blocks of foamed concrete.
• Foamed concrete blocks can be milled, drilled, grooved, planed, sawed with a hand saw right on the construction site.
• According to the technology, the support zones of the lintels and the zones under the windows, as well as the next four to five rows of blocks, must be laid with reinforcing meshes.
• On the last row of foam concrete blocks, in the panel formwork preparation, reinforced-reinforced mortar screed, 20-25 cm thick, is produced. On the outside, the reinforced concrete belt is heat-shielded with a 5-cm layer of extruded polystyrene foam.

Brick finish

The most ancient wall material for the construction of a dwelling is, undoubtedly, facing brick, which, apart from the wealthy appearance, is characterized by significant (up to 200 kg / sq. cm) strength and low (less than 6%) moisture absorption, which explains the long life cycle of stone households. In addition to the usual ones, clinker, figured and glazed bricks are produced among the facing brick products.

Now produced face brick of all kinds of textures (corrugated, chipped, rough, smooth) and profiles (beveled, rounded, rectangular, wedge-shaped), as well as colors (from light yellow to dark brown), which helps to realize any original artistic ideas.

• From the outside, on the foam concrete wall, with the help of polymer anchors, slabs of basalt fiber thermal protection (for example, Isover, Izorok, Ursa, Knauf, Izomin, Rockwool) are tightly hung with a cross section of 50 mm, on top of which a vapor-permeable waterproofing membrane is laid (Izospan, Tyvek, Yutavek ).
• Every 2 rows of blocks, they arrange the coupling of the facing and foam concrete walls by laying bending galvanized strips or soft fiberglass mesh reinforcement, due to the fact that the facing and foam block wall parts have an unequal degree of shrinkage.
• Brickwork is done in spoon rows on a cement-sand mortar, alternating every 4-5 rows of spoons with a butt row.
• Since there is a risk of shrinkage cracks, it is not recommended to connect the foam block and brickwork rigid reinforcing rods laid in the seams of the walls.
• From the front wall, the main wall made of foam blocks, with an external thermal insulation screen, is separated by a gap, at least two centimeters (along the entire height of the floor), for the output of wet steam, with the implementation of supply and exhaust openings at the upper and lower points of the front masonry.

Block-prefabricated strip foundation

Blocks differ in types: FBP - hollow foundation blocks, FBV - with a cutout, FBS - solid ,. As a rule, foundation blocks are made with a height of up to 0.65 m, the horizontal size changes in the range of 900-2400 mm, the width is fixed at 30,40,50,60 cm.

When making strip foundation on non-porous substrates, it is quite possible to lay concrete blocks directly on the compacted soil base.

The use of a certain type of FBS-block results from the thickness of the external structures of the house. For low-rise construction quite the width of the reinforced concrete block is 300 or 400 mm. Section of FBS blocks m.b. thinner than the outer walls of the building, since they have a much higher load capacity.

On non-porous soils, it is permissible to lay out building blocks without orderly reinforcement, provided that a reinforced tape with a height of 0.10-0.20 m with a reinforcing mesh is poured from below and above them.

Reinforced concrete blocks are considered a classic building component, which allows you to quickly make the foundation of a private house.

To increase the area of ​​the foundation base, in order to thereby reduce possible movements of the continental soil, the FBS blocks should be mounted on pre-assembled foundation supports.

The choice of FBS blocks as a material for making a foundation is often motivated by the possibility of year-round construction or a time limit.

In situations where the characteristics of the underlying layer are not clear, it is better for peace of mind, instead of FL blocks, to arrange a monolithic reinforced concrete screed.

Today, a foundation made of reinforced concrete elements, according to a set of basic properties, among which: resistance to movement of the geo-foundation and efficiency, is inferior to another type - a monolithic reinforced foundation.

• The laying of foundation cushions begins from the outer corner of the building, and first the FL blocks are laid under the outer walls, and only then for the inner ones.
• On the crushed stone preparation or laid foundation supports with bandaging, FBS are placed - blocks that are joined with a sand-cement mixture.
• The assembly of the finished blocks is carried out relative to the corners, along the walls diverging at right angles, controlling the alignment along the optical theodolite. Separate reinforced concrete blocks are placed with a forklift on the “bed” of the masonry mixture.
• Masonry should be started with the placement of reference blocks in the corners of the building and at the intersections of the axes. The placement of wall blocks is started only after checking the position of the extreme blocks in plan and in height.
• The geometry in the plan is checked by measuring the linear size of the sides of the house and the size between opposite corners, and the height level - according to the spirit level or level.
• Windows for launching into the zero level of pipelines are implemented, making a niche between the blocks, with further embedding with concrete.

Prefabricated reinforced concrete floor

For the device of intermediate floors in buildings with brick walls, as a rule, reinforced concrete hollow-core panels are used.

During construction low-rise building, in most cases, panel products of the PK, PNO brand are used with dimensions: from 2100 mm to 6300 mm in length, 0.16 ÷ 0.22 m in thickness and 0.99 ÷ 1.19 m in width.

Through technology prestressing reinforced concrete, prefabricated slabs, are characterized by a large margin of safety, in comparison with overlappings made on the same site in a monolithic form, as well as by the stability of technical parameters, at a cheaper cost and quick erection of the constructed overlap.

Unlike cast reinforced concrete floor, reinforced concrete hollow-core panels are distinguished by good soundproofing properties.

Some points of laying reinforced concrete slabs:

• Before laying the floors, look at the level of the bearing surfaces of the girders and masonry, which should lie in the same plane: the spread in the marks can be in the range of 1.0 ÷ 1.5 cm, if necessary, the bearing plane is brought with a sand-cement mixture ...
• The slabs are lowered by a truck crane onto the cement-sand bed, a small movement is done manually, before the slings are removed, if a mismatch in levels with the adjacent slabs is more than 5 mm, the product is removed, the mortar bedding is replaced and re-laid.
• Immediately after the alignment of the floor, the mounting ears are welded with wall anchors and with lifting fasteners of adjacent products, and the interpanel slots are sealed with a cement mixture to the full thickness of the reinforced concrete panel.
• To compensate for structural movements, there should be a gap of up to 5 cm between the masonry and the support area of ​​the floor panel, and at the same time, to protect against freezing, it is worth inserting a polystyrene foam insulation into this indent.
• For the purpose of thermal protection of the ceiling in winter, it is necessary to fill the cavities in the end sections of hollow-core ceilings with expanded clay-concrete mixture 120 ÷ 200 mm deep.

Profiled metal roof

Compared to metal roofing, the main benefits of corrugated roofing are ease of installation and minimum costs.

Profiled material is sheets of trapezoidal profiled metal rolling, with a film paint coating, which are produced under brands such as НС18, Н57, Н44, С-21, B-45, НС35, MP-35, Н60, НС44, where the numbers mean the height of the corrugation ...

As a material for the roof, a profiled sheet with a corrugation height of at least 2 cm is used to obtain the required load capacity and economical use of lathing boards. In this case, the permissible slope of the roof slope is considered to be at least 1: 7.

The roof covering is laid on a rigid structure consisting of rafters and lathing preparation.

For private buildings, a two or three-span scheme with medium retaining walls and inclined rafters is usually used.

The spacing between the rafter legs is usually made in the range of 0.60 ÷ 0.90 m with a standard size of rafter beams 50x150 ÷ ​​100x150 mm; the lower ends of the rafter legs are lowered onto a fixing bar measuring 10x10 ÷ 15x15 cm.

Standard installation instructions for corrugated sheets of corrugated board:

• In situations of construction of warm attic spaces, roofing based on corrugated sheets, like every other metal roofing surface, requires a subroofing moisture-proof film, such as: Stroizol SD130, TechnoNIKOL, Yutavek 115,135, Tyvek, Izospan, which prevents condensed water vapor from dripping onto the heat insulator ...
• The moisture-proof film is laid with horizontal strips, from bottom to top, with a sagging between the rafter legs of about 2 cm and an inter-strip overlap of 10-15 cm, with further gluing the joints with adhesive tape.
• To exclude unnecessary horizontal joints, the longitudinal component of the corrugated sheet is made equal to the shoulder of the roof slope, plus 20 ÷ 30 cm, taking into account the lower overhang.
• The interval between the lathing bars is set by the profile section and the slope of the roof: when the latter is more than 15-17 °, and the profile grade is НС-8-НС-25, then the step of installing the lathing flooring is chosen 0.4 meters, and for profile grades НС-35- NS-44 - will be 70-100 cm.
• The installation of corrugated sheets of profiled decking should be carried out from the eaves zone of the roof sidewall, opposite to the prevailing wind direction, in order to avoid lifting them under wind loads.
• The profiled sheeting is fixed to the battens with self-tapping screws, size 30x4.8 mm, with rubber gaskets, in the lower half-wave, and the ridge corners, on the contrary, in the raised wave zone. Along the line of the cornice, fastening occurs at all deflections of the corrugated sheet, and the consumption of screws is up to 8 units. per 1 m2 of roof surface.
• The lateral overlap of the profiled canvases is required to be performed in one wave, and at an angle of the roof slope less than 11 ÷ 12 degrees - in 2 waves.
