The investment boom in the construction trade, warehousing, industrial and other objects made popular pre-fabricated buildings for investors, customers, and for general contracting organizations. This is explained by two factors – indeed rapidly build facilities and reduce the cost of construction compared with traditional materials – for example, brick or precast concrete. Hence – the rapid increase in technological developments in construction and building structures, especially technology so-called "rapid construction – installation of prefabricated buildings of metal and sandwich panels, which is the most advanced to date in the construction of industrial and commercial buildings. buildings are most preferred for commercial applications because of their installation allows you to bypass a lot of complex construction stages. The use of metal structures and sandwich wall and roof panels ensure full compliance with the building erected all structural and engineering requirements and allows you to create a modern design. Thermal insulation of sandwich panels creates optimal conditions for working people in these areas. Metal structures, used for assembling pre-fabricated buildings vary in profile, the thickness and purpose.
For example, (sin-beams), which were used recently, much lighter than traditional metal construction, although the strength of brand they do not concede. There weight and other technological features in the construction of prefabricated buildings. For example, the compound structure by welding or bolts. Really high-assembling the building is provided by Application of high-strength bolted connections and lack of on site welding and the use of screws for mounting the walls and roof of the panels. In construction practice, two major type of installation of prefabricated structures.
The first time at the construction site are imported steel, sandwich panels, windows, doors and other building structures and materials. On-site mounted metal frame and tied off " sandwich panels. In the second, the so-called "modular" method on an object brought collected for production elements for the future of the building, which is mounted directly on the site. But this method is used for construction light buildings.
