Description

Technical Field

[0001] The invention relates to the technical field of bridge bearings, and in particular to an urban road bridge bearing. Background Art

[0002] Urban roads are an important part of the urban transportation system. Their planning, design and management directly affect the city's traffic efficiency, safety and the quality of life of residents. Bridge bearings are important structural components connecting the superstructure and substructure of the bridge. They are located between the bridge and the pad stone. They can reliably transfer the load and deformation borne by the superstructure of the bridge to the substructure of the bridge, and are important force transmission devices of the bridge.

[0003] For example, a bridge bearing is disclosed in the publication number: CN220099634U, which relates to the field of bearing technology; the bridge bearing includes a base plate, a rubber seat is bonded to the upper surface of the base plate, a fixed seat is bonded to the outer surface of the rubber seat, an opening is opened on the lower surface of the fixed seat to match the rubber seat, a fixing mechanism is installed on the outer surface of the fixed seat, a shock-absorbing mechanism is installed on the outer surface of the fixing mechanism, and a clamping mechanism is matched on the lower surface of the shock-absorbing mechanism. Through the fixing mechanism, the shock-absorbing mechanism and the clamping mechanism, the force transmitted from the top plate to the rubber block can be effectively shared, thereby reducing the wear of the rubber block, improving the service life of the rubber seat, and thus reducing the number of times the rubber seat is replaced. Moreover, through the shock-absorbing mechanism, the position of the rubber seat is not easy to shift when it is subjected to displacement and angular force. Through the annular tube, it is only necessary to inject water into the annular tube to reach the marked horizontal line position to see whether the rubber block is shifted, which is convenient to use.

[0004] Based on the above patent solution and existing related technologies, the bridge bearings currently used still have the following problems: 1. It is impossible to achieve a good positioning effect on the rubber block, which makes it easy for the rubber block to move during the installation process; although some bridge bearings are equipped with a rubber block positioning structure, it is easy to affect the normal deformation of the rubber block; 2. The bridge bearing cannot be automatically grouted after installation, resulting in the need for workers to grout at a higher position during grouting, which increases the difficulty of grouting and also poses a safety hazard; 3. The friction between the anchor and the mortar is small, which makes it easy for the anchor to loosen from the mortar, affecting the anchoring effect. Therefore, we propose an urban road bridge bearing to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to make up for the shortcomings of the prior art and propose an urban road bridge bearing, which plays a positioning role for the circular rubber block. Under the premise of ensuring the positioning effect, the normal deformation of the circular rubber block is not affected; the four inclined pushing frames can push the eight movable sealing plates to move outward, so that the mortar in the mortar storage shell is automatically discharged through the four rectangular mortar discharge ports; the loosening of the anchoring connecting screws and the dried mortar is avoided, and the anchoring effect is improved; the problems of easily affecting the normal deformation of the rubber block, the need for workers to grout at a higher position during grouting, and the small friction between the anchor nails and the mortar are solved.
