LOWER FRAME STRUCTURE AND FITTINGS
To suppress deterioration of fireproof performance.SOLUTION: A lower frame structure 5 is a lower frame structure having a lower frame 22 provided at an opening of a building body B. The lower frame 22 includes a hollow portion 71. In the hollow portion 71, a reinforcing member 6 is provided. An upper surface 712a of a lower wall portion 712 constituting the hollow portion 71 has an inclined surface 712b inclined downward toward an outdoor side. The reinforcing member 6 has an upper facing surface 614 opposed to a lower surface 711b of an upper wall portion 711 constituting the hollow portion 71, a lower opposing surface 631 opposed to the upper surface 712a of the lower wall portion 712, and a protruding portion 64 protruding downward from the lower opposing surface 631.SELECTED DRAWING: Figure 3
【課題】防火性能の低下を抑制すること。【解決手段】下枠構造５は、建物躯体Ｂの開口部に設けられる下枠２２を有する下枠構造である。下枠２２は、中空部７１を備える。中空部７１内には、補強材６が設けられている。中空部７１を構成する下壁部７１２の上面７１２ａは、室外側に向けて下方に傾斜した傾斜面７１２ｂを有する。補強材６は、中空部７１を構成する上壁部７１１の下面７１１ｂに対向する上対向面６１４と、下壁部７１２の上面７１２ａに対向する下対向面６３１と、下対向面６３１から下方に突出する突起部６４とを備える。【選択図】図３
