SUPPORTING FRAME OF BOX UNIT Russian patent published in 1994 - IPC

FIELD: construction of foundations. SUBSTANCE: supporting frame of box unit includes binding of transverse carrying members and longitudinal carrying members with load-lifting journals. To reduce specific consumption of materials with single-direction loading, the frame has flexible couplings located along longitudinal carrying members. Flexible couplings made in form of branches passing over the load-lifting trunnions from atop, and secured to the middle and to ends of lower belt of longitudinal carrying members. To reduce specific consumption of materials with reversed loading, the frame has additional flexible couplings passing over load-lifting trunnions from below and secured to the middle and to ends of upper belt of longitudinal carrying members. EFFECT: higher efficiency. 2 cl, 4 dwg
