Construction a building for any purpose implies that it will create an environment that is comfortable for humans or optimal for the operation of technological equipment. The complex of elements designed to create this kind of environment is called - network engineering. The main parameters that engineering networks are designed to form are air temperature and humidity, air purity, the speed of its movement and the provision of inflow, as well as illumination, the availability of hot and cold water, electricity, the removal of production products or human activity, etc.

Control over the operation of engineering systems can be carried out in semi-automatic or automatic mode, including remotely.

Engineering systems are a necessary component of any building, regardless of its purpose. Creating conditions that are optimal for human existence requires maintaining air temperature and its purity at a certain level, the availability of electricity and water, sewage systems, etc. A feature of industrial buildings is that they require the creation of not only standard engineering networks, but also certain technological communications.

The design of engineering systems today is a complex complex of many components. At the same time, every detail of the project must be thought out. The slightest deviation from the rules entails operational problems.

Designing utility networks is an art. The art of making a person's life comfortable and safe.

CONCLUSION Testing the load-bearing capacity of a hollow-core slab according to series 1.041.1-3 (pdf 340 Kb) technical report

The essence of the third method is the regulation of stress, due to which the forces are redistributed or reduced throughout the entire structure. This method is simpler and alternative to the second method, requires less accurate mathematical calculations and allows for redistribution without stopping the technological process. The necessary parts are connected by welding, bolts or polymer solutions.
Thus, taking into account the technical condition of the structure and the selected tasks, one or another activity is selected. Depending on the structure that needs to be strengthened, one or another method of designing reinforcement is chosen. For example, when designing strengthening of reinforced concrete structures, the following should be taken into account.
Strengthening as a result of which individual structural parts are replaced with stronger elements - these are reinforced concrete or metal frames, reinforced concrete jackets, or the use of additional schemes - consoles, racks, metal beams, combined tightening to the original structure.
Reinforcement entails lower costs than replacement with new products. In addition, in the second case there is no need to stop production. You should also pay attention to the fact that in some areas it is possible to carry out reinforcement, but in others it is not, they are simply replaced by others.

In other words, subject to strengthening:

reinforced concrete foundations,
columns, beams,
floor slabs,
reinforced concrete crane beams.

If a reinforced concrete truss is found to be in disrepair, it is replaced with a new one; strengthening is strictly prohibited. Before strengthening reinforced concrete structures, it is necessary to perform a number of points - this is preparing the surface that will be strengthened, installing the correct reinforcement and connections, and formwork. Surface preparation is necessary for reliable adhesion to the concrete that will be used for reinforcement. This is achieved by cleaning the surface from dirt by blowing air, and cleaning the fittings with sandblasting machines from corrosion. When laying concrete mortar, it is more advisable to use pneumatic installations.

Designing reinforcement with metal structures is different and is done differently. It is used to add additional, both flexible and rigid elements, to strengthen the joints of structural connections, as well as to completely eliminate individual elements. To increase the load-bearing capacity of individual elements, the structure is supplemented with parts, securing them with bolted connections or welding.
Designing reinforcement with wooden structures makes it possible to reduce the cost of construction work. The low weight of the tree does not require the construction of additional foundations, which leads to a reduction in material consumption. The measures are applicable in both warm and cold rooms with external water drainage. The temperature and humidity of the environment should be taken into account to avoid fire and rotting of the wood. Coniferous species are used to strengthen wooden structures. However, for keys and liners, which is a critical connection, it is better to use hardwood. These are oak, ash, birch, which have high strength and bending resistance.
It is recommended to keep the oak in water for some time to enhance its strength. In addition to the above, various polymers strengthen the joints. These are various epoxy resins, the so-called diane, polymer concrete based on polyester and furan resins, bitumen-epoxy mastics as a waterproofing coating.
Recently, with increasing technological progress, carbon fiber has begun to be used in the design of reinforcements. Carbon fiber has a number of advantages - tensile strength characteristics are 10 times higher than steel, and the material is tiny in thickness, which does not affect the cross-sectional dimensions of the reinforced structure. In addition, carbon fiber is lightweight, the original structure is not overloaded, and there is no need for foundation reinforcement measures.
In addition to the main advantages, the share of installation and labor work is removed. There is no need to use welding equipment, lifting mechanisms, there is no need to completely or partially stop production. The main disadvantage is the high cost of the material itself, but the material is durable, resistant to corrosion, deformation and, as noted above, more reliable, durable and easier to handle when compared with the listed technologies.

As you can see, there are many methods and methods for designing reinforcement of building structures. The choice of solution depends on the result and the tasks you want to accomplish.

In the construction of non-residential buildings, metal structures are often used. Their application is based on the data in the section of the design documentation entitled “Metal structures”.

In general, working documentation on structures can be divided into two groups. The first is direct documentation on metal structures.

It is compiled on the basis of technical design materials for the subsequent creation of detail drawings. The second part is detailing metal structures. In this case, all structural elements are worked out separately. These drawings can serve as the basis for the production of metal structures at enterprises (if necessary).
The design of metal structures includes plans and sections of the object’s structures, design solutions for elements, options for their interface, and metal specifications. At this stage, the structures are linked to other parts of the project. Structural calculations are drawn up in the format of a calculation and explanatory note.
Detailed designs of metal structures consist of drawings of individual elements of all metal structures and installation diagrams.

When designing a section of metal structures, a number of basic requirements are taken into account. First of all, operating conditions - they determine the structural form of structures and the most suitable type of material.
The second requirement is saving metal. This is easily explained, since metal is an expensive building material. Therefore, it is used most often in cases where the use of other materials (for example, reinforced concrete) is not rational.
The next factor is manufacturability. Projects are drawn up taking into account technological requirements for the installation of metal structures, with an emphasis on modern installation methods. This has the effect of reducing the labor intensity of the process.
In addition, when developing a project, the aesthetics of finished metal structures and the harmony of their shapes are taken into account. This is especially important when development is carried out within the city, taking into account the requirements of the city authorities for the architectural forms of objects.
The project of the section “Metal structures” is carried out by specialized design organizations. When designing, three indicators are achieved, on which the cost of metal structures and the work on their assembly depends. This means saving steel, increasing labor productivity, reducing labor intensity and installation time.

Section of architectural and construction solutions "AS"

The architectural and construction solutions section "AS" does not contain a calculation part, is not produced in accordance with GOST - it combines the main construction parts of the sections AR, KR and partially KZH, KM, KD with elements of KMD, etc. It is developed at the request of the customer and includes a sufficient amount of information for carrying out construction and installation work as a simplified manual on construction and major repairs for a novice construction manager or foreman. The AC section can be completed with production technology, conditions and installation diagrams. You can additionally order an assembly drawing for an additional cost.

I have been working in the design field for over 10 years.

In fact, there is nothing complicated in agreeing on a working project. All you need is time and desire. After the design decision has been made, it is necessary to obtain a decision from local authorities on the reconstruction or design of a building (supermarket, store, pharmacy, etc.). After receiving this document, you must contact a licensed design organization to develop a detailed design. The next stage is ordering technical specifications from city services (Vodokanal, Energy Supply Organization, City Heating Networks).

To order technical specifications, the design organization provides engineering loads (electricity, water, heat, etc.). And with these loads, the BTI passport (if there is an existing building and reconstruction is taking place), it is necessary to contact the appropriate authorities. After the technical specifications are received, they need to be transferred to the design engineers.

They are also developing a passport for exterior finishing and a master plan. As soon as one of the sections is ready, you need to take 2 copies of the corresponding section, technical specifications, the original master plan and go to the authority to approve the section, i.e. if the VK section (water supply and sewerage) then to Vodokanal, etc.

When all sections have been agreed upon, namely: VK, OV (heating and ventilation), EMO (power supply and electric lighting), and the seals of these authorities have been affixed to the original master plan, a full working draft (GP, AC, TX, VK, OV, EMO) and an explanatory note should be taken to Rospotrebnadzor and the same project to the City Emergency Management Department (to the city service - to the firefighters). It is necessary to obtain opinions on the working draft from these authorities. In parallel with the approval of sections, you can also agree on a passport for exterior finishing. The next stage after receiving the conclusions is the completion of a working draft for approval by the city engineer, in order to obtain a square stamp on the general plan.

We complete a full working design (GP, AS, TX, VK, OV, EMO and PZ), as well as the conclusion of Rospotrebnadzor and the State Emergency Service. After receiving the square seal on the master plan, we prepare a working draft at GASN (State Architectural and Construction Supervision) to obtain a protocol for the approval of working documentation.

The main rule when coordinating is to follow the movement of the original sections and the master plan. At the approval stage, documents with blue seals are the most important documents. In general, this is the most common scheme, but each working project has its own nuances and additional approvals are possible. Good luck!!! Denis Korablev
