Abstract

Results: To reduce the cost of construction, it is proposed to use large building blocks with air slotted voids of the "nf15" type of Pobeda-Knauf company, which allows you to sharply reduce the amount of material for their manufacture; it makes the blocks lighter, and the presence of voids ensures the preservation of heat in the premises. In addition, the use of metal joints and composites that allow you to create in the factory articulated, quick-assemble, modular sections, armed with lock-free connections of parts, dramatically reduces the conduct of installation (de-installation). The simulation of the influence of air voids on durability of building blocks method "allowable stress" subject to "creep" completely eliminate possible doubts about the quality of these blocks and showed that the length of a possible crack growth the load can be increased, but the voltage at the vertices of the unit is clearly reduced. The rejection of expensive cement mixes in masonry, which significantly reduce its strength, and the transition to the use of smooth "beds" of monoblocks, which can be achieved by using appropriate forms during their "casting", as well as the use of appropriate adhesives for their additional binding contributes to further cost reduction. The scope of the results: The results obtained can be widely used in the practice of building con-struction, for calculating the permissible stresses in large building blocks with air slits of different configurations.
