The invention relates to a seamless connection stress relief joint for high-speed rails. The seamless connection stress relief joint is characterized in that a group of mechanical guide gauges and thehigh-speed rails are designed to be installed and fixed on the same concrete roadbed to form a whole, and two outer ends of a 1A section and a 2B section of each guide gauge are correspondingly butt-welded at the connection part of the rails. According to the design scheme, the 1A section and the 2B section are combined in a concave-convex up-and-down staggered and movable fit mode, a certain gapis reserved between the 1A section and the 2B section, the impact force of kinetic energy of a high-speed rail motor car on a connecting point can be effectively controlled, the effect that the steelrail connector is connected without a break point is achieved, and the effect of stable and safe operation can be achieved; and meanwhile, the maintenance operation cost is effectively reduced.
本发明涉及一种高铁钢轨无缝连接应力消除接头，设计一组机械导规与高铁钢轨安装固定在同一混凝土路基上成为整体，并把导规‑1A段与‑2B段外边二头分别对点焊接于钢轨连接处，利用‑1A段与‑2B段凹凸上下交插动配合组合并留有一定量的间隙的应力自动消除接头，并能有效控制因高铁动车动能对连接点的冲击力，达到钢轨连接头成无断点连接的效果，并能平稳安全运行效果的设计方案，同时有效减少维护运行成本。
