RAIL FASTENING DEVICE
To provide a rail fastening device for a turnout capable of installing a rail brace without inclining the rail.SOLUTION: A rail fastening device comprises: a floor plate having a sliding part of a tongue rail, a mounting part of a stock rail, and a spring holding part provided at a prescribed position opposite to the sliding part; a rail brace that is attached to the floor plate while being in contact with the side surface of the stock rail mounted on the rail mounting part; and a spring member engaged with the spring holding part and which presses a lower flange of the rail toward the floor plate via the rail brace. A guide groove is formed at a prescribed angle with the rail mounting part at a prescribed position outside the spring holding part of the floor plate. The rail brace has a recess to avoid interference with the spring holding part. A pressing part having a shape corresponding to the shape from the jaw of the stock rail to the web and a part of the lower flange is provided at the tip, and a protruding part capable of engaging with the guide groove is provided at the rear end of the lower surface. An opening is provided in at least one of a pair of side walls.SELECTED DRAWING: Figure 4
【課題】レールの傾倒作業を伴うことなくレールブレスを設置することができる分岐器用レール締結装置を提供する。【解決手段】トングレールの摺動部と基本レールの載置部と摺動部の反対側の所定位置に設けられたばね保持部とを有する床板と、レール載置部に載置された基本レールの側面に接触した状態で床板に装着されるレールブレスと、ばね保持部に係合されレールブレスを介して本レールの下部フランジを床板へ向かって押圧するばね部材と、を備えたレール締結装置において、床板のばね保持部よりも外側の所定位置にレール載置部と所定角度をなすガイド溝を形成し、レールブレスには、ばね保持部との干渉を回避するための凹部を有し、先端に基本レールの顎部から腹部および下部フランジの一部かけての形状と対応する形状を有する押圧部を、また下面後端にガイド溝に係合可能な突出部を設け、一対の側壁のうち少なくとも一方に開口を設けた。【選択図】図４
