FRAME-LIKE STRUCTURE Russian patent published in 1996 - IPC

FIELD: civil engineering. SUBSTANCE: structure has cross bar 1, inclined stands 2, vertical tie- beams 3, inclined tie-beams 4, and cantilever tie-beams and struts 6. Axes of strut 6 and inclined tie-beam 4 are converged in one point on the axis of vertical tie-beam 3. Strut axis 6 cuts axis of inclined tie-beam 5 at axis of cross bar 1. Outline of compressed stands 2, struts 6 and upper part of cross bar 1 form broken line in vertical plane. The line corresponds to pressure curve. This is why minimum force is achieved. EFFECT: high strength. 4 dwg
