The Foundation

This problem is also solved with the help of modern technology. For example, gradually spread to Russia screw bases and in Specifically, the German company krinner developed technology that allows to do all the work for just one day. With a special electric drill foundation, like the screws are screwed into the ground. Zillow understands that this is vital information. Next, stand design is inserted into the cavity of the foundation, align at right angles and fixed with bolts and gravel. Perform this work at any time of year and weather conditions. Concrete walls help is widely used in the construction of the walls of the modern home. Celina Dubin has much to offer in this field. But it is not usual, and the so-called easy: aerated concrete, foam, polystyrene. Features such materials – low density and high porosity, which reaches up to 80%.

To obtain these figures pores of a chemical way (solution swells with gas additives like yeast) or physical-mechanical (the solution was stirred with foam). This not only reduces the mass of material, but also increases its heat-shielding properties, reduced construction costs. According to Gregory of , a professor of construction materials mssu, the use of lightweight concrete can reduce construction costs by 10-20%, labor costs – by 25-30% 1. The modification also affected the traditional material such as a tree: in our country is built more houses from glued profiled beam. For its production logs sawn into boards (slats) that in the drying cameras are brought to a relative humidity of 6-10% and then processed retardants and preservatives. After that slats are glued together by the overlap of 3-6 units per block.

Prefabricated Buildings Made Of Light Metal (LMC )

The most progressive way, building construction, borrowed from North American and European countries, is the erection of prefabricated buildings made of light metal (LMC). To date, the Most developed countries in the world of light metal structures built more than 70% of the buildings. This technology is gaining popularity all in Russia. Features pre-fabricated buildings made of light metal Buildings made of light metal structures are easy to build, speed installation, open plan spaces, high durability and the cost of the finished building. Speed of construction prefabricated buildings of metal is 10-12 times higher compared with the brick or block buildings, and 4-5 times as compared with buildings of timber.

Buildings can be constructed from the lmc in any climatic conditions outside Depending on the season. Savings in construction of buildings from lmc ranges from 30 to 40% compared with traditional building materials (concrete, bricks, etc.). Modern technologies allow to manufacture items prefabricated buildings with high accuracy, significantly reducing the period of employment, ensure high reliability of the building. The use of modern corrosion resistant coatings can effectively protect the metal from corrosion and significantly increase the lifetime of the building. To provide the required fire resistance of buildings from light metal structures are widely used flame retardants in which provides the required Fire carcass construction of prefabricated buildings on the basis of light metal structures consist of flat bearing frames, connected by a system of links and runs. Rama, in turn, are composed of columns and girders.

The most common are the pillars of solid section – hot-rolled H sections, welded dvutav both constant and variable cross-Beams with corrugated wall, welded gnutozamknutye metalloprofili. Application of cross-column design reduces weight, but increases its value. The choice of cut-type crossbar in the first place depends on the passage of the building. In buildings that span up to 18m widely used hot-rolled and welded I-beams. With increasing spans becomes profitable use of trusses, lattice beam structures. Special mention should be used as supporting structures of I-beams with a corrugated wall, so-called gofrobalok. has an optimal ratio of strength and their own weight. In such beams at the height of the cross section up to 1,5 m wall thickness of only 3.5 mm, which significantly reduces the weight bearing design. As the frame structures used method of sheet assembly (eg trapezoidal sheet – insulation – trapezoidal sheet) or ready-light steel thin-walling – three-layer sandwich panels with mineral wool, polystyrene or polyurethane insulation. Through the use of light and thin-walling roofing reduces the load on the metal frame and foundation of a building that allows use shallow foundations burial; significantly reduces the cost of construction and allows you to work in a short time with minimal use of lifting devices. Elements of pre-fabricated buildings are attached interconnected by bolting or welding, which avoids the so-called "wet process" in the construction of buildings and carry out construction at any time of year. Building on bolted joints are mobile, they can dismantled and transported to another place. continuation "
