COLUMN/BEAM JOINT PART STRUCTURE AND DIAPHRAGM

摘要

PROBLEM TO BE SOLVED: To provide a column/beam joint part structure and a diaphragm facilitating the wiring work, etc., by providing a wire conduit through-hole or a notch for laying a wire conduit or a wire duct in the diaphragm joined by welding in a part surrounded with a flange and a web in a weak axis direction of an H-steel column. SOLUTION: This steel frame structure of two-directional rigid-frame structure uses the H-steel column 1 and steel beams 2a and 2b. The wire pipe through-hole 6 for laying the electric wire pipe for laying an electric wire, etc., is provided in the diaphragm 4b joined by welding in a part surrounded with the flange and the web of the steel column 1 in the joint part between the steel column 1 and the steel beams 2a and 2b.
