STAIRCASE TREAD BOARD FIXTURE, STAIRCASE PROVIDED WITH THE FIXTURE, AND STAIRCASE TREAD BOARD FIXING METHOD
PROBLEM TO BE SOLVED: To provide a fixture and a method for fixing a tread board on a beam of an open staircase, the fixture being fitted readily and allowing wide-range and stepless adjustment of an inclination angle of the tread board.SOLUTION: A tread board fixture (10) has a triangular structure formed by interconnecting a beam fixing part (11) fixed on a beam (1) side, a tread board fixing part (12) fixed on a tread board (2) side, and reinforcing parts (20, 30) situated between the fixing parts (11, 12). The reinforcing parts (20, 30) are made of an expansion member, so as to allow adjustment of an angle of the tread board (2) to a horizontal level, to suit an inclination angle of the beam (1). The expansion member may be a turnbuckle mechanism (20) or a similar mechanism (30). A connecting part between each of a beam fixing part (51), the tread board fixing part (12) and the reinforcing parts (20, 30) may be insertion grooves (52, 53) into which a connecting member of the part to be connected can be inserted, instead of a connecting hole.
【課題】オープン階段の桁に踏み板を固定するための、取り付け容易で踏み板の傾斜角度を広い角度範囲でかつ無段階で調整可能な踏み板固定具、同固定方法を提供する。【解決手段】踏み板固定具（１０）は、桁（１）側に固定される桁固定部（１１）と、踏み板（２）側に固定される踏み板固定部（１２）と、両固定部（１１、１２）の間に介在する補強部（２０、３０）とが相互に連結された三角構造を形成している。桁（１）の傾斜角度に応じて踏み板（２）の角度を水平に調整できるよう、補強部（２０、３０）は伸縮部材から構成されている。伸縮部材は、ターンバックル機構（２０）もしくはこれに類似する機構（３０）とすることができる。桁固定部（５１）と踏み板固定部（１２）と補強部（２０、３０）の各連結部は、連結穴の代りに相手側の連結用部材を差し込み可能な差し込み溝（５２、５３）としてもよい。【選択図】図２
