BUILDING CONSTRUCTION Russian patent published in 1998 - IPC

FIELD: construction, applicable for erection of walls of buildings and structures. SUBSTANCE: building construction has two parallelepipeds put together in such a way that on two adjacent faces they form grooves, and on the two others- bosses. One of the parallelepipeds is a rectangular one, and the faces of the other are bevelled, owing to which triangular grooves are formed on the two adjacent sides, and triangular bosses- on the opposite sides. At erection of walls of buildings and structures the bosses of one construction enter the grooves of the two adjacent ones. In the first place, the grooves of this construction receive the recesses of the two other adjacent constructions. The end face of the boss adjoining the rectangular parallelepiped may be made flat, due to it, a system of interconnected ducts is formed in the wall. For the sake of efficiency the rectangular parallelepiped may be made broken - in the form of right angles. When it is necessary to form a window opening, the parallelepiped with bevelled faces is made in the form a frame. EFFECT: reduced labour content, simplified production, enhanced reliability and isolation of rooms. 3 cl, 8 dwg
