FIELD: construction.SUBSTANCE: invention relates to construction, in particular, to erection of prefabricated foundations of industrial and civil buildings. The prefabricated foundations includes flat trapezoidal boards that are mutually crossing. Crossing of two and more boards may be made at equal angles between boards, also with reduction of the angle in direction of high moment loads. Boards rest onto a cut in a support board. Trapezoidal boards are joined via a vertical slot in the middle part or made as displaced aside with lower moment forces, and a column base has slots for fixation.EFFECT: increased bearing capacity, reduced material intensity and labour intensiveness.2 cl, 6 dwg |
