FIELD: construction.SUBSTANCE: lock prefabricated strip footing includes a support slab and rows of foundation slabs arranged on it. The support slab has a face inclined and bonder surfaces, the upper rib for a slot fixation into a lock of the above block. Foundation units have vertical and horizontal slots, protruding beyond faces of the bed and outbond surface by 1/3 of the width, at the same time the last row of the strip footing is arranged from a block, having a flat upper horizontal surface for resting of wall materials when erecting above walls.EFFECT: reduced labour intensiveness of foundation blocks assembly, increased accuracy of foundation blocks installation, reduced deviations from horizontal and vertical planes, higher resistance of foundation blocks to displacement due to application of geometric parameters of a foundation block.5 cl, 1 ex, 6 dwg |
