Description

Technical Field

[0001] This utility model relates to the field of bridge component technology, and in particular to a bridge bearing. Background Technology

[0002] Bridge bearings are crucial structural components connecting the superstructure and substructure of a bridge. They reliably transmit the reactions and deformations (such as displacement and rotation) of the superstructure to the substructure, ensuring that the actual stress conditions match the calculated theoretical models. Existing bridge bearings generally consist of an upper bearing plate, a lower bearing plate, and a lining assembly between the upper and lower bearing plates. The lining assembly typically comprises a polymer wear-resistant plate and a polyurethane elastomer. The polymer wear-resistant plate is a consumable component in bridge bearings and requires regular maintenance and replacement. In existing sliding high-load-bearing polyurethane bearings, the polymer wear-resistant plate and polyurethane elastomer are manufactured as a single unit, making it impossible to replace the polymer wear-resistant plate separately. However, in actual use, the lifespan of the polyurethane elastomer in the bearing is far longer than that of the polymer wear-resistant plate. Replacing the polymer wear-resistant plate necessitates replacing the polyurethane elastomer as well, resulting in material waste and significant replacement costs. Therefore, further improvements to existing bridge bearings are necessary. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a bridge bearing with wear-resistant plates that can be disassembled and replaced separately, in view of the above-mentioned existing technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a bridge bearing, including an upper bearing plate and a lower bearing plate, wherein a liner assembly is provided between the upper bearing plate and the lower bearing plate, characterized in that: the liner assembly includes an elastic plate, an inner liner plate and a wear-resistant plate arranged sequentially from bottom to top, the elastic plate is located above the lower bearing plate, the inner liner plate is fixed to the top of the elastic plate, and the wear-resistant plate is installed on the top of the inner liner plate and supported below the upper bearing plate.

[0005] Preferably, the bottom of the upper support plate is provided with a stainless steel sliding plate, which is clamped between the wear-resistant plate and the upper support plate.

[0006] To better position the wear-resistant plate on top of the inner liner, the top of the inner liner is formed with a mounting groove, and the lower part of the wear-resistant plate sits within the mounting groove.

[0007] To make the mounting structure of the liner assembly more robust, the inner liner is connected and fixed to the elastic plate via connectors. Alternatively, the inner liner can also be connected and fixed to the elastic plate by vulcanization.

[0008] The connector can have various structures; preferably, the connector is a screw.

[0009] In order to improve the structural strength of the elastic plate, the elastic plate is a polyurethane elastomer, and a horizontally distributed steel plate is arranged in the elastic plate.

[0010] Further preferably, the steel plate is at least two and is spaced apart in the up-down direction.

[0011] In order to mount the support on the beam body, the upper support plate and the lower support plate are both provided with connecting bolts.

[0012] Compared with the prior art, the advantages of the bridge support lining plate assembly are as follows: the lining plate assembly comprises an elastic plate, an inner lining plate and a wear-resistant plate arranged in sequence from bottom to top, the elastic plate is arranged above the lower support plate, the inner lining plate is fixed on the top of the elastic plate, the wear-resistant plate is arranged on the top of the inner lining plate and is supported below the upper support plate, the wear-resistant plate and the elastic plate are designed in a separated mode, the wear-resistant plate can be replaced alone in the maintenance process, the elastic plate in normal operation is not replaced, the replacement cost is greatly reduced, material waste is avoided, the bridge support has a simple and reasonable structure and does not affect the original performance of the support, and the service life of the bridge support is prolonged.
