FIRE-RESISTING BOARD SUPPORT STRUCTURE FOR CURTAIN WALL, AND COMPOSITE FIRE-RESISTING COATING STRUCTURE OF STEEL BEAM

摘要

PROBLEM TO BE SOLVED: To suppress breakage of a fire-resisting board for a longitudinal frame.SOLUTION: A fire-resisting board support structure 10 for a curtain wall includes: fire-resisting boards 60 for the curtain wall which are arranged on both right and left sides of a metallic longitudinal frame part 22Y; a bracket 62 for supporting the fire-resisting boards 60 for the curtain wall on a skeleton; a fire-resisting board 70 for the longitudinal frame which covers the longitudinal frame part 22Y from an interior side and is structurally separated from the fire-resisting boards 60 for the curtain wall; and a pair of upper brackets 72 and a pair of lower brackets 82 for supporting the fire-resisting board 70 for the longitudinal frame on a steel beam 14.
