COLUMN FIREPROOF STRUCTURE OF WOODEN COLUMN-EXPOSED WALL

摘要

PROBLEM TO BE SOLVED: To provide a column fireproof structure of a wooden column-exposed wall that can continue to support load from a building by effectively compensating the degradation of a buckling proof stress of the column even when the column exposed on the wall surface of the column-exposed wall receives direct heating in case of fire.;SOLUTION: The column fireproof structure 10 of the wooden column-exposed wall is provided for improving the buckling proof stress, in case of fire, of the wooden column 12 of square cross section with a front part 12a appearing on the wall surface 11a of the column-exposed wall 11. The interior held by front and rear wall members 14, 15 constituting the wall surfaces 11a, 11b of the column-exposed wall 11 is provided with a proof stress reinforcing attached member 16 mounted in an integrally joined state over almost the total length of the column 12 through an adhesive 17 along a side face part 12b or a back face part 12c of the column 12.;COPYRIGHT: (C)2010,JPO&INPIT
