CONNECTION STRUCTURE, TREAD PIECE, SPIRAL STAIRS, AND ASSEMBLY METHOD FOR SPIRAL STAIRS
To provide a connection structure and a tread piece which facilitate connection work, and spiral stairs using the tread piece and an assembly method for spiral stairs.SOLUTION: A spiral stairs include a plurality of tread pieces 20 connected to each other. The tread piece 20 has a tread body 21, a fitting projection 25 extending in a first direction H1 from the tread body 21, a first engagement recess 26 which is opened to the side face of the fitting projection 25 and extends in a second direction H2 crossing the first direction H1, a fitting recess 31 to which the fitting projection 25 of the other tread piece 20 is fit, and an engagement hole 35 which extends in the second direction H2, and communicates with the first engagement recess 26 of the other tread piece 20 in a state where the fitting projection 25 of the other tread piece 20 is fit into the fitting recess 31. An engagement material is inserted into the engagement hole 35, and the first engagement recess 26 of the other tread piece 20 in the communication state.SELECTED DRAWING: Figure 2
【課題】接続作業が簡単な接続構造および踏板ピース、ならびに、該踏板ピースを用いた螺旋階段および螺旋階段の組立方法を提供する。【解決手段】螺旋階段は、互いに接続される複数の踏板ピース２０を有する。踏板ピース２０は、踏板本体２１と、踏板本体２１から第１方向Ｈ１に延びる嵌合凸部２５と、嵌合凸部２５の側面に開口して第１方向Ｈ１と交差する第２方向Ｈ２に延びる第１係合凹部２６と、他の踏板ピース２０の嵌合凸部２５が嵌合する嵌合凹部３１と、第２方向Ｈ２に延びて、他の踏板ピース２０の嵌合凸部２５が嵌合凹部３１に嵌合した状態において他の踏板ピース２０の第１係合凹部２６に連通する係合孔３５と、を有する。連通状態にある係合孔３５と他の踏板ピース２０の第１係合凹部２６とに対して係合材が挿入される。【選択図】図２
