TESTING RAIL
To provide a testing rail capable of suppressing cost.SOLUTION: A test rail 20 can be divided into at least a plurality of components including a bottom part 30 on which a rail fastening tool 10 is attached and a head part 40 on which a test load is applied. A shape of an upper surface 34 of an end part of the bottom part 30 in a width direction is the same as a shape of an upper surface 7s of a lower end part 7 of a joint plate 5 attached along the rail 1. The plurality of components each include a web part 50 arranged between the bottom part 30 and the head part 40. At least one of the plurality of webs 50 different in height is arranged between the bottom part 30 and the head part 40.SELECTED DRAWING: Figure 1
【課題】コストを抑制することができる試験用レールを提供することである。【解決手段】試験用レール２０は、少なくとも、レール締結装置１０が装着される底部３０および試験荷重が印加される頭部４０の、複数の部品に分割可能である。底部３０の幅方向の端部の上面３４の形状は、実レール１に沿って装着される継目板５の下端部７の上面７ｓの形状と同等である。複数の部品は、底部３０と頭部４０との間に配置される腹部５０を含む。高さの異なる複数の腹部５０のうち少なくとも一つが、底部３０と頭部４０との間に配置される。【選択図】図１
