FIRE RESISTIVE COVERING STRUCTURE, FIRE RESISTIVE COVERING MATERIAL AND CONSTRUCTION METHOD OF FIRE RESISTIVE COVERING STRUCTURE

摘要

To prevent a fire resistive covering material from floating up from a steel frame consisting of a skeleton column or falling down due to its self weight.SOLUTION: A fire resistive covering structure (1) comprises: a steel frame (10) consisting of a skeleton column; and a pair of fire resistive covering materials (20) for covering the steel frame (10). The steel frame (10) comprises: a pair of flanges (11); a web (12) for coupling the pair of flanges (11); and a projection (13) arranged on both sides of the web (12) and extending in parallel with the pair of flanges (11). On each of the pair of fire resistive covering materials (20), notch parts (21) and (22) in three rows for receiving the pair of flanges (11) of the steel frame (10) and the projection (13) are formed when the pair of fire resistive covering materials (20) covers the steel frame (10) from both sides.SELECTED DRAWING: Figure 1
