Detailed Description

The utility model is further illustrated by the following examples:

as shown in fig. 1 to 3, a temporary short sleeper device for rail joints comprises sleeper bottom iron base plates 2 arranged below rail gaps between adjacent rails 1, wherein elastic short sleepers 3 are fixedly connected above the sleeper bottom iron base plates 2, and specifically, the sleeper bottom iron base plates 2 and the elastic short sleepers 3 are adhered into a whole through high-strength adhesives. The elastic short sleeper 3 is made of any one of a wood material, a rubber material or a resin material, so that the elastic short sleeper 3 can buffer impact vibration generated by downward ends of the steel rail when a train passes.

An elastic rubber plate 4 is closely connected below the steel rail 1, the elastic rubber plate 4 is fixedly connected with a pillow top lifting supporting plate 5, and specifically, the elastic rubber plate 4 and the pillow top lifting supporting plate 5 are stuck into a whole through a high-strength adhesive. The centers of the sleeper bottom iron backing plate 2, the elastic short sleeper 3, the sleeper top lifting support plate 5 and the elastic rubber plate 4 are overlapped with the center of the rail gap between the adjacent steel rails 1.
