摘要

PROBLEM TO BE SOLVED: To provide fire resistant cover technology for a steel beam, ensuring fire resistance as well as constructing efficiency (transportability) by partially covering the steel beam.;SOLUTION: With the sectionally H-shaped steel beam 10 being supported at its both ends, a ceiling slab 80 is mounted on an upper flange face 12. The steel beam 10 is covered with a fire resistant cover material 30. At this time when the steel beam 10 is covered with the fire resistant cover material 30, the steel beam 10 is wound by a felt molding member while leaving at least the upper flange face 12 contacting a ceiling slab 80 and an edge face 13 of an upper flange 11 as well as both end supporting portions 26, 26 of the steel beam 10.;COPYRIGHT: (C)2005,JPO&NCIPI
