<P>PROBLEM TO BE SOLVED: To provide a fire resistant structure for a wooden column-exposed wall, which can be easily provided when remodeling a building, and which can effectively compensate reduction in buckling yield strength when the wall surface of the column-exposed wall receives heating in case of fire. <P>SOLUTION: A fire resistant structure 10 of a wooden column-exposed wall, in which the front face parts 12a of a column 12 are exposed on wall surfaces 11a, 11b of a partition bearing wall to form a column-exposed wall 13, improves buckling yield strength in case of fire. A wooden receiver 16, to which wall surface members 15 are joined along the side surface part 12b of the column 12, is attached over substantially whole length of the column 12, and a bent reinforcing fitting 17 of U-shape in cross section including two side portions 17a, 17b connected to each other at a right angle is attached over a length of 30% or more the column 12 along the wooden receiver 16, in a state in which the side portion 17a of one side is joined to an outer side surface part 16a of the wooden receiver 16 by machine screws 18 and the side portion 17b of another side is disposed along an inner side surface of the wall surface members 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
