STAIRCASE STEP BOARD MOUNTING STRUCTURE

To provide a staircase step board mounting structure that can easily and precisely fix step boards while ensuring the design quality.SOLUTION: The invention relates to a step board mounting structure for a staircase with a pair of side panels 1 arranged at intervals and a step board 2 installed on a horizontal part 12 in the side panel 1. A tip hole 4 is formed, which extends in a straight line from the inner surface of the side plate 1 toward the horizontal part and whose upper end slopes outward relative to the lower end; and a head part 61 of a fixture with the head part 61 provided on the base end side of a shaft part 62 is placed on the lower end of the tip hole 4, and the tip side of the shaft part 62 is fixed to the lower side of the step board 2 while the shaft part 62 penetrates the side plate 1 through the tip hole 4, thereby securing the step board 2 to the side plate 1.SELECTED DRAWING: Figure 2 【課題】意匠性を確保しつつ、段板を簡単かつ精度良く固定ができる階段の段板取付構造を提供する。【解決手段】本発明は、間隔をおいて配置される一対の側板１と、側板１に設けられた水平部１２に設置される段板２とを備えた階段の段板取付構造を対象とする。側板１の内面から水平部に向けて直線状に延び、かつ上端側が下端側に対し外側に傾斜する先孔４が形成され、軸部６２の基端側に頭部６１が設けられた固定具の頭部６１が先孔４の下端側に配置されて軸部６２が先孔４を通じて側板２を貫通した状態で軸部６２の先端側が段板の下面側に固定されることによって、段板２が側板１に固定されている。【選択図】図２
