METHOD OF MANUFACTURING LIGHT-WEIGHT METAL BEAM

摘要

construction industry. SUBSTANCE: method includes cutting of initial beams by broken lines and joining of obtained parts into light-weight beams. In so doing, one beam becomes symmetrical in section relative to middle of length and low height on supports, and the other beam is symmetrical in section with the same height over entire length. EFFECT: reduced labor input in beam manufacture, higher load-carrying ability of beam. 4 dwg
