FIREPROOF STRUCTURE, FIREPROOF STRUCTURE CONSTRUCTION METHOD, AND FIXING METAL FITTING

摘要

A fireproof structure 1 is formed by covering a beam 5, which is a structure, with a fireproof covering material 11. A fixing metal fitting 7 is disposed between a pair of flanges 13 formed in the beam 5. The fireproof covering material 11 is fixed to the fixing metal fitting 17. In this case, the fireproof covering material 11 is fixed to the fixing metal fitting 7 by piercing a projection of the fixing metal fitting 7 into the fireproof covering material 11. The fireproof covering material 11 is a flexible member. The beam 5 is covered with the fireproof covering material 11 by fixing the fireproof covering material 11 to the beam 5 in a state of being wound therearound.
