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
