Description

Elastic supporting structure and pre-pressing device Technical Field The utility model relates to the technical field of bridge construction, in particular to an elastic supporting structure and a pre-pressing device. Background The elastic supporting structure is a key elastic element in the bridge expansion device, and plays roles of bearing and noise reduction. In the operation process of the bridge expansion device, the compression support in the traditional elastic support structure is exposed to the external environment for a long time, the compression support is subjected to the influence of the load of the vehicle sliding with the hanger of the bridge expansion device at any time, and is easy to age and even damage, so that the elastic support structure is invalid, and therefore the invalid compression support needs to be replaced. When the existing compression support is replaced, the sliding support is taken out after the hanging frame is lifted, the hanging frame is lowered to replace the new compression support, the hanging frame is lifted again to restore the sliding support after replacement, the replacement process is complicated, and the efficiency is low. Disclosure of utility model The embodiment of the utility model provides an elastic supporting structure and a pre-pressing device, which are used for solving the technical problems of complicated process and low efficiency of the compression supporting replacement of the elastic supporting structure in the related art. In a first aspect, embodiments of the present utility model provide an elastic support structure comprising: An elastomer; the upper supporting plate and the lower supporting plate are respectively arranged at the upper end and the lower end of the elastic body; And the connecting piece penetrates through the connecting through holes of the lower supporting plate and the elastic body and is detachably connected with the upper supporting plate. In some embodiments, the upper support plate comprises: the threaded through hole is communicated with the connecting through hole, and one end of the connecting piece penetrates through the connecting through hole and is in threaded connection with the threaded through hole. In some embodiments, further comprising: and the limiting ring is arranged on one surface, far away from the elastic body, of the lower supporting plate, and the limiting ring and the connecting through hole are concentrically arranged.
