RAIL FASTENING DEVICE FOR TURNOUT
PROBLEM TO BE SOLVED: To provide a rail fastening device for a turnout, which enables a rail to be fastened with ease.SOLUTION: In a rail fastening device 100 for a turnout, a leaf spring member 20 is attached between a body part 11 and an overhanging part 13 of a floor board 10 in a state in which one end 20a of the leaf spring member 20 is placed on a lower flange 1a of a stock rail 1. After that, a wedge member 30 is inserted between the other end 20b of the leaf spring member 20 and the body part 11, and fixed to the body part 11. Thus, the lower flange 1a of the stock rail 1 is urged in such a manner as to be pressed against the body part 11 by the one end 20a of the elastically-deformed leaf spring member 20, and the stock rail 1 is fastened to the floor board 10.
【課題】レールの締結を容易に行うことができる分岐器用レール締結装置を実現する。【解決手段】分岐器用レール締結装置１００において、板ばね部材２０の一端２０ａを基本レール１の下部フランジ１ａに載せた状態で、その板ばね部材２０を床板１０における本体部１１と張出部１３との間に取り付けた後、板ばね部材２０の他端２０ｂと本体部１１の間にくさび部材３０を挿し込んで、そのくさび部材３０を本体部１１に固定することによって、弾性変形させた板ばね部材２０の一端２０ａで基本レール１の下部フランジ１ａを本体部１１に押さえ付けるように付勢して、基本レール１を床板１０に締結するようにした。【選択図】図１
