CONNECTION MEMBER FOR STAIRS
To provide a connection member for stairs that does not expose metal fittings at connection parts of the stairs, such as a connection part between a bridgeboard girder and an above-story structural member, and is strong at the connection part.SOLUTION: There are provided connection members 10, 20 for stairs for joining two members 1, 2. The connection members 10, 20 are each composed of a first connection metal fitting 10, a second connection metal fitting 20 and a connection bolt B. The first connection metal fitting 10 is provided with a first upper plate 13 having a hole 13a for passing the connection bolt B and a first engaging portion 15. The second connection metal fitting 20 is provided with a second upper plate 23 having a hole 23a to be screwed with the connection bolt B and a second engaging portion 22 having a guide groove 22a opening at the top. And the first engaging portion 15 falls into the second engaging portion 22 to make the first connection metal fitting 10 and second connection metal fitting 20 fit together, and the first upper plate 13 and the second upper plate 23 are connected through the hole 13a of the first upper plate 13 with the connection bolt B.SELECTED DRAWING: Figure 6
【課題】ササラ桁と階上構造部材との接続部分のように階段の接続部分において金具が露出せず、しかも接続部分の強度が強い階段用の接続部材を提供する。【解決手段】２つの部材１，２を互いに接合する階段用の接続部材１０，２０であって、接続部材１０，２０は第一接続金具１０と第二接続金具２０と接続ボルトＢとからなり、第一接続金具１０には、接続ボルトＢを通す孔１３ａを有する第一上板１３と、第一係止部１５が設けられ、第二接続金具２０には、接続ボルトＢと螺合する孔２３ａを有する第二上板２３と、上方が開口する案内溝２２ａが形成された第二係止部２２が設けられ、第一係止部１５が第二係止部２２に落ち込んで、第一接続金具１０と第二接続金具２０が嵌合状態となるとともに、第一上板１３の孔１３ａを介して第一上板１３と第二上板２３とを接続ボルトＢで接続した。【選択図】図６
