FIELD: construction.SUBSTANCE: prefabricated foundation shell includes an external shell with an expansion in a lower part, resting against a board or a prepared foundation. The shell comprises flat trapezoidal boards installed vertically, as inclined with equal angles of boards inclination, and with the largest angle of boards inclination, which are opposite to direction of action of highest moment forces, or from jointly installed vertical and inclined boards. The inclined board is made at the opposite side of directing actions of highest moment forces and is parallel to the side of the support board. The joint of mutually crossing trapezoidal boards is made via vertical or inclined as arranged symmetrically to a slot in upper and lower parts of the boards by half of their height. All opposite composite trapezoidal boards have smaller size. In the upper part of the foundation a column base is made as through under single or double branch column.EFFECT: increased bearing capacity, reduced labour intensiveness and material intensity.2 cl, 8 dwg |
