BUILDING AND FRAME OF BUILDING SKELETON Russian patent published in 1994 - IPC

FIELD: construction of buildings. SUBSTANCE: braces are located in frame plane and secured with their lower end to middle twin-branch columns at distance of 0.3-0.4 of its height from cap. The other end of rigid braces is secured to gantry beams, respectively, at distance of 0.3-0.35 of width of frame middle span, and 0.9-0.95 of width of frame extreme span. Crossbars are attached with their upper end to gantry beams in middle and extreme spans, and with their lower end, to braces. Braces are arranged at different inclination to horizontal and have same length of horizontal projection. Columns, beams braces, crossbars and posts of framework are made of single or twin Σ-shaped roll-formed sections. One part of tension bars are parallel to gantry beams in the middle of span between them; the other part of tension bars is located in cells formed by girders positioned towards building center, adjacent girders and gantry beams, and connected to first tension bars with one end, and to girders with the other end. Ties are arranged in cells formed by outer, adjacent tension bars and girders, and attached with one end to gantry beams, and with the other end, to girders. Ties and tension bars located in cells form Y-shaped stiffener in roofing plane. EFFECT: higher efficiency. 17 cl, 18 dwg
