Zusammenfassung:	To suppress transmission of fire heat from one side to the other side across a fireproof partition wall through a space between a steel frame fireproof member and the fireproof partition wall even if the steel frame fireproof member covered with a decorative timber is heated.SOLUTION: A fireproof structure includes a fireproof partition wall and a steel frame fireproof member formed such that a steel frame member is covered with a decorative timber and the fireproof partition wall is abutted to the steel frame fireproof member. A fire stop member is used for the decorative timber at a part to which the fireproof partition wall is abutted. A burning member is used for the decorative timber at a part where the fire stop member is not used.SELECTED DRAWING: Figure 1 【課題】化粧木材の被覆が施された鉄骨耐火部材が加熱された場合でも、鉄骨耐火部材と防火区画壁との間を通して、防火区画壁を挟んで一方側から他方側への火熱の伝達を抑制することである。【解決手段】耐火構造は、防火区画壁と、鉄骨部材に化粧木材が被覆され、防火区画壁が突き当てられている鉄骨耐火部材と、を備え、防火区画壁が突き当てられる部分の化粧木材には、燃え止まり材が用いられており、燃え止まり材が用いられていない部分の化粧木材には、燃え代材が用いられている。【選択図】図１
