CONCRETE COLUMN FOR FIREPROOF

摘要

PURPOSE: A fireproof concrete column is provided to maintain a fireproof efficiency by controlling temperature rise of a post, and reduce a construction period and cost. CONSTITUTION: A fireproof concrete column comprises a main panel composed of a first partition panel(110) and a second partition panel(120) and concrete placed an inside space where the first partition panel and the second partition panel are coupled. A plurality of ribs(111,121) for joint efficiency of concrete are formed in longitudinal direction inner surface of the first partition panel and the second partition panel. A plurality of discharge holes(114,124) in which steam of concrete is discharged in case of a fire are formed on the surface of the first partition panel and the second partition panel.
