BMZ design and technology

The efficiency of prefabricated buildings is ensured by the design and use of metal structures of various profiles, sizes and purposes. Structural elements are calculated separately and in combination with connections and delivered to the construction site for further installation by welding or threaded connections.

According to the current standards, critical structural elements are made of durable steel (C255, C345 and their analogues according to international standards). Metal products with high strength characteristics are used:

• In load-bearing frames of industrial facilities with large spans and significant dynamic and static loads;
• For the construction of warehouses, agricultural farms, retail outlets, car washes and other commercial facilities;
• For the arrangement of floors;
• As various connections between elements;
• In special structures: bunkers, gas holders and other tanks for gas, liquids and bulk materials, in blast furnaces and other industrial units;
• In the construction of bridge and other types of lifting mechanisms;
• In the assembly of towers, masts, power transmission towers and other high-rise objects.

Despite the diversity, all structural elements are designed to perform certain functions, which may vary depending on the layout of prefabricated buildings.

Main parts of prefabricated buildings

The basis of any object is a reliable foundation, the type and size of which depends on the characteristics of the building. In the general sense of the word, a foundation means a structure located below the ground level, which is designed to receive loads from the elements located above.

Due to the low weight of prefabricated buildings, it is possible to abandon the complex strip foundation and limit it to columnar structures for each column. The pillars are buried below the ground freezing level or, in difficult conditions, are based on piles.

The task of the walls is to take the load from the roof and ceilings, as well as to isolate the interior space from certain environmental influences. There are self-supporting walls, which bear their full load up to the point of transferring it to the foundation, and load-bearing walls, which bear only their own weight and only within one vertical span (floor).

Ceilings are important internal structures that zone the space into floors and can perform both enclosing and load-bearing functions: they can support the weight of equipment, people, etc. Another purpose of floors is to ensure the spatial rigidity of the entire building or part of it. The functional features of the floors are determined by the place of its layout. There are:

Posts (columns) are vertical structural elements that take the axial compression load and serve to support horizontal floors, walls and roofs. The most common types are columns of various types.
Crossbars (beams) are horizontal load-bearing elements that transmit loads from floors to columns.
Purlins are secondary roof beams that work in conjunction with the girders. One of the areas of application is the basis for a roofing pie.

Any frame of any building is a complex bundle of posts, crossbars and girders.

The roof is an extremely important structural element that protects the interior from above. The main requirement for the roof is tightness. Together with the attic floor, the roof forms the building’s covering. A variation is an atticless floor.

Partitions are thin walls that, as the name implies, divide the area of a separate level into separate rooms. Not being load-bearing, they can be easily dismantled without any problems for the stability of the building.

Stairs are structural elements for moving between levels.

Gates (doors) – provide access to the building and, when closed, isolate it from external factors.

Options for concrete buildings

Concrete (or more precisely, reinforced concrete) structures are widely used in various elements of a building: in foundations, in columns, in floors, in walls, etc. There are two technologies: precast and reinforced concrete, each of which has its own characteristics.

Precast concrete is manufactured according to standards or special orders at the factory and delivered to the construction site ready-made (block, slab, column, etc.), where it is installed directly into the design position using lifting mechanisms. This approach minimizes the labor costs of builders and allows the construction of facilities in the shortest possible time, regardless of weather conditions. Among the main disadvantages:

• Heavy weight – requires strong foundations;
• High cost;
• Restrictions on dimensions and weight (caused by transportation and storage);
• The need for lifting mechanisms;
• The presence of a large number of joints – potential cold bridges;
• The need for constant maintenance (sealing of joints).

Monolithic reinforced concrete is delivered to the construction site in liquid form, where it is poured into pre-prepared formwork with a reinforcing mesh. This approach is much cheaper than using monolithic structures, and it is not tied to “ready-made forms,” meaning that it makes it possible to erect building elements of any, even the most complex, configuration and impressive size. Correctly poured reinforced concrete has no imperfections (hence the name) and can withstand static and alternating loads well.

Among the key disadvantages:

• The need to strictly adhere to the delivery and pouring schedule;
• The need for special equipment for delivery to the site (less often – for the production of concrete on site) and pouring;
• The presence of “wet” processes;
• Dependence on natural factors (season, rain, etc.);
• Duration of installation: the speed of pouring is limited by the time required for hardening and “gaining strength”.

Modern concrete

These and other operational shortcomings have led to the emergence of new types of concrete – cellular concrete. In which the main emphasis was placed on reducing the weight of the material, as well as, due to the porous structure, improving the thermal protection properties of the material.

Foam concrete and aerated concrete are supplied in blocks and have their own differences compared to classic masonry concrete (one of the limitations is rather low strength). Despite the convenience and speed of installation, the materials have significant drawbacks:

• The need to protect the outer surface from the negative effects of the environment;
• Difficulty in fixing “heavy” and complex elements;
• The presence of a large number of joints – potential areas of increased heat loss;
• Restrictions on use as load-bearing elements in buildings with heavy loads.

The post Concrete buildings: significant disadvantages appeared first on Bafuture.

Planning of agricultural buildings and complexes

The general term “agricultural buildings” unites a large group of structures for various purposes. A common feature is that they rarely have many floors, but often have large areas. The absence of heavy loads eliminates the need for powerful lifting mechanisms (which are available in factories), so the loads on the frame are minimal, which often allows you to abandon powerful foundations and bulky supporting structures.

There are several types of agricultural buildings:

• Livestock facilities – for the cultivation of one (less often – several) species of animals;
• Greenhouse facilities – for the production of vegetables, fruits, berries, flowers, seedlings, etc;
• Warehouses – for short-term or permanent storage of agricultural products;
• Processing facilities: conservation, drying, packaging, elevators, etc;
• Auxiliary buildings – for staff, equipment, veterinary services, laboratories, etc.

Basic requirements for agricultural buildings

Different objects in agriculture serve different purposes. Hence the differences in the key requirements for design. The most “demanding” are livestock farms, where it is necessary to provide:

• The required temperature regime;
• Optimal ventilation, humidity and lighting;
• Sufficient space for healthy livestock (with separate areas for young animals, isolation of sick animals, etc;)
• Areas for mechanization, cleaning and storage of products and waste.

Livestock facilities have a complex network of utilities, including water, electricity, wastewater disposal, and sometimes gas for heating.

Storage warehouses have fewer “connections”. The main emphasis here is on protection against negative environmental factors: moisture, dust, etc. For some products, a set temperature regime is important.

The design of processing facilities similar to industrial facilities depends entirely on the technology. Regardless of the purpose, livestock facilities must have convenient access roads and, of course, provide sanitary conditions for the working staff.
