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

FIELD: construction of industrial buildings. SUBSTANCE: lattice gantry beams rest on both branches of twin column with their lower belt with bringing into coincidence of points of intersection of axes of two extreme braces at each end face of gantry beams with the axes of inner branch and column upper brace. Angle of inclination of column upper brace to horizontal exceeds angle of inclination of extreme rising brace of gantry beam. Girders of framework posts, column branches, belts, outer posts, and two extreme braces at each end face of gantry beams are made of twin Σ-shaped roll-formed sections, and crossbars and braces of columns and remaining posts and gantry beam braces are made of single S-shaped roll-formed sections. Distance between branches of each column is 0.45-0.55 of distance between attachment points of intermediate braces to each of column branch and 0.74-0.80 of distance between axes of belts of each gantry beam. Lower belts of adjacent gantry beams are interconnected by crossbars located on central longitudinal axis of building, and girders located above building are installed in pairs. EFFECT: higher efficiency. 18 dwg
