RAIL TEMPERATURE EXPANSION JOINT AND LAYING AND MOUNTING METHOD

A rail temperature expansion joint and a laying and mounting method thereof are disclosed by the present disclosure which relate to the technical field of track transit. The rail temperature expansion joint of the present disclosure includes a sleeper, the upper surface of the sleeper is symmetrically mounted with two first rails and two second rails, and the first rail and the second rail on one side are arranged on the same straight line; a gap is arranged between end faces of the first rail and the second rail; the adjacent ends of the first rail and the second rail are fastened and positioned by a group of adjustment components, the adjustment components are fixedly mounted on the embedded part, and the embedded part is located at the outer side of the first rail and the second rail. The rail temperature expansion joint and a laying and mounting method thereof of the present disclosure connects a first rail and a second rail with a side plate through two groups of connecting rods, so that when a train passes by, the connecting rods drive a sliding plate to slide in a sliding groove at the outer end of the side plate, meanwhile, the buffer spring stretches, which prevents the train from derailing due to an overlarge gap generated when the first rail and the second rail are pulled; compared with steel plate connection, the connecting rod has longer service life.
