The invention discloses a steel rail joint device for improving wheel-rail impact and a construction method thereof.The steel rail joint device comprises a steel rail joint, the steel rail joint comprises a joint clamping plate used for connecting adjacent steel rail ends, a joint pedal extends out of the joint clamping plate, and the joint pedal extends to a steel rail surface and makes contact with a wheel tread; the two sides of a rail head of each steel rail end are provided with cutting faces cut to a rail seam, the cutting faces on the adjacent steel rail ends form a groove matched with the joint pedal in shape, and after the joint clamping plates are installed on rail webs of the steel rail ends, the joint pedals are tightly attached to the grooves. The joint clamping plate is arranged on the joint clamping plate, so that the joint clamping plate provides a walking surface for a train wheel in a steel rail end connecting area, the wheel does not directly roll a rail seam of a steel rail end any more, impact generated when the wheel passes through the rail seam of the steel rail end is eliminated, and it is ensured that a train can stably pass through the steel rail end connecting area.

本发明公开了一种改善轮轨冲击的钢轨接头装置及其施工方法，包括钢轨接头，其中钢轨接头包括用于连接相邻钢轨端头的接头夹板，接头夹板上延伸出接头踏板，接头踏板延伸至钢轨轨面并与车轮踏面接触，钢轨端头的轨头两侧设有切削至轨缝的切削面，相邻钢轨端头上的切削面组成了与接头踏板形状相契合的凹槽，接头夹板安装在钢轨端头的轨腰后，接头踏板与凹槽紧密贴合，使得接头夹板在钢轨端头连接区域为列车车轮提供了一个行走面，使得车轮不再直接碾压钢轨端头的轨缝处，以消除车轮在通过钢轨端头轨缝时产生的冲击，确保列车能够平稳通过钢轨端头连接处。
