FIRE RESISTIVE COVERING STRUCTURE OF STEEL FRAME MEMBER
To restrain decrease of fire resistance efficiency of a steel frame member.SOLUTION: A fire resistive covering structure of a steel frame member comprises a steel pipe 12, a plurality of ligneous fire resistive covering materials 30 placed around the steel pipe 12 and fireproof covering the steel pipe 12, a plurality of corner substrate materials 40 having a pair of flange parts 40A bending along corner parts 30C where end parts of adjacent ligneous fire resistive covering materials 30 are butted and with each end part attached, and erected around the steel pipe 12 to support adjacent ligneous fire resistive covering materials 30, and a pair of intermediate substrate materials 70 each formed in a C-shaped cross section, erected between adjacent corner substrate materials 40 in a back to back state, and supporting the ligneous fire resistive covering material 30. A joint of adjacent ligneous fire resistive covering materials 30 is placed on the pair of intermediate substrate materials 70, end parts of the ligneous fire resistive covering materials 30 are attached by machine screws respectively.SELECTED DRAWING: Figure 3
【課題】鉄骨部材の耐火性能の低下を抑制することを目的とする。【解決手段】鉄骨部材の耐火被覆構造は、鋼管１２と、鋼管１２の周囲に配置され、鋼管１２を耐火被覆する複数の木質耐火被覆材３０と、隣り合う木質耐火被覆材３０の端部が突き当てられた隅部３０Ｃに沿って屈曲されるとともに該端部がそれぞれ取り付けられる一対のフランジ部４０Ａを有し、鋼管１２の周囲に立てられ、隣り合う木質耐火被覆材３０を支持する複数のコーナー下地材４０と、断面Ｃ字形状にそれぞれ形成されるとともに、互いに背合わせ状態で、隣り合うコーナー下地材４０の間に立てられ、木質耐火被覆材３０を支持する一対の中間下地材７０と、を備え、一対の中間下地材７０上には、隣り合う木質耐火被覆材３０の目地が位置し、該木質耐火被覆材３０の端部がビスでそれぞれ取り付けられている。【選択図】図３
