| Zusammenfassung: | To provide a substrate structure fixing a bracket portion of a stair handrail to an inter-floor part.SOLUTION: A stair handrail substrate structure 1 in an inter-floor part is a structure serving as a fixed substrate for fixing a bracket 21 supporting a stair handrail 2 of a stair 100 to an indoor wall of an inter-floor part 3. The stair handrail substrate structure 1 comprises: an inside wall board 7 becoming the indoor wall; and a substrate member 5 provided on an indoor side face of a web 41 of a steel girth 4 located in the inter-floor part 3 and receiving an indoor side face of the inside wall board 7 to prevent the inside wall board 7 from being displaced (pushed-in) toward the web 41 side.SELECTED DRAWING: Figure 1
【課題】階間部に階段手摺のブラケット部を固定する下地構造を提供する。【解決手段】階間部の階段手摺下地構造１は、階段１００の階段手摺２を支持するブラケット２１を階間部３の屋内壁に固定する固定下地となる構造である。階段手摺下地構造１は、上記屋内壁となる内壁ボード７と、階間部３に位置する鉄骨胴差４のウェブ４１の屋内側面に設けられており、内壁ボード７の屋外側面を受け止めて内壁ボード７のウェブ４１側への変位（押し込まれ）を抑止する下地部材５と、を備えている。【選択図】図１ |
