RAIL FASTENING DEVICE AND RAIL FASTENING METHOD
To provide a rail fastening device capable of being easily changed from a screw fastening type rail fastening device to a non-screw fastening type rail fastening device.SOLUTION: A rail fastening device 1 has a shaft member 4 fixed to a bearing body 2, a spring member 5 arranged between the bearing body 2 and a head part 4b of the shaft member 4, and a frame member 6 inserted between a spring member 5 and the head part 4a to surround a shaft part 4a of the shaft member 4. The shaft member 4a includes a spherical surface part 17. The frame member 6 includes a spherical surface part 18 formed on the upper surface of the frame part 14, and two tapered parts 19 respectively connected to both end parts of the frame part 14. In the rail fastening device 1, the frame member 6 is inserted between the spring member 5 and the head part 4b so that the spherical surface part 18 is fitted to the spherical surface part 17, and a rail bottom part 3b is pressed by the spring member 5 to fasten a rail 3 to the bearing body 2.SELECTED DRAWING: Figure 2
【課題】螺締式のレール締結装置から無螺締式のレール締結装置に容易に変更することができるレール締結装置を提供する。【解決手段】レール締結装置１は、支承体２に固定された軸部材４と、支承体２と軸部材４の頭部４ｂとの間に配置されたばね部材５と、軸部材４の軸部４ａを囲むようにばね部材５と頭部４ｂとの間に挿入された枠部材６と、を有する。軸部材４ａは球面部１７を含む。枠部材６は、枠部１４の上面に形成された球面部１８と、枠部１４の両端部の各々にそれぞれ接続された２つのテーパ部１９と、を含む。レール締結装置１は、球面部１８が球面部１７と嵌合されるように、ばね部材５と頭部４ｂとの間に枠部材６が挿入され、ばね部材５によりレール底部３ｂが押圧されることにより、支承体２にレール３を締結する。【選択図】図２
