FIELD: construction engineering, particularly, prefabricated reinforced concrete constructions for flat roofs and floors with high service loads. SUBSTANCE: construction is formed by installation on supporting piles and interconnection of many reinforced concrete blocks formed by component interrelated parts. Novelty consists in that construction is formed of, at least, four located in couples reinforced concrete U-shaped blocks installed on horizontal transverse parallel beams secured to ends of, at least, three transverse parallel rows of vertical supporting parts of supporting piles. Side surfaces of each U-shaped blocks are made in form of two double-T members installed on horizontal transverse parallel beams secured to couple of transverse parallel rows of vertical supporting posts of supporting piles and perpendicular to them. Double-T members are interconnected by means of flat plate installed on horizontal surfaces of facing each other upper parts of double-T members and forming upper surface of U-shaped block. Horizontal surfaces of facing each other external upper parts of double-T members of each couple of U-shaped blocks installed on said horizontal parallel beams are interconnected by additional parallel beams are interconnected by additional parallel beams are interconnected by additional flat plate installed on them and connecting the horizontal surfaces of facing each other external upper parts of double-T members of each couple of U-shaped blocks joined with their side and surfaces to facing them side end surfaces of said flat plates of the first couple of U- shaped blocks. In this case, the second couple of U-shaped blocks is installed on horizontal transverse parallel beams secured to couple of transverse parallel rows of vertical supporting posts of supporting piles. In this case, horizontal transverse beams secured to vertical supporting posts of supporting piles of middle transverse row are common for the first and second couples of U-shaped blocks. The second couple is connected with the first couple of U-shaped blocks by combined end surfaces of homogeneous members comprising and connecting U- shaped blocks of the first and second couples. Vertical supporting posts are installed on caps of supporting piles. EFFECT: reduced specific consumption of materials, costs, labor input transportation and mounting, facilitated manufacture of components, increased reliability and longevity of offered construction. 5 cl, 5 dwg
