Description

Technical Field

[0001] This utility model relates to the field of expansion joint technology, specifically a noise-reducing expansion joint. Background Technology

[0002] Expansion joints, also known as building expansion joints, are structural joints designed to prevent building components from cracking or being damaged due to thermal expansion and contraction caused by changes in climate temperature. They are mainly used in bridge construction.

[0003] During the design phase, the structure is pre-disconnected in deformation-sensitive areas, leaving gaps to ensure that the disconnected parts of the building have sufficient deformation space to prevent damage or cracks. To improve the noise reduction effect within the expansion joint, a noise reduction structure needs to be installed inside the expansion joint. However, the noise reduction effect of the existing expansion joint structure is relatively average, and when vehicle tires drive over the rubber pads installed on top of the expansion joint, they will put pressure on the rubber pads, resulting in a low service life of the rubber pads. Therefore, a noise reduction expansion joint is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a noise-reducing expansion joint to solve the problems mentioned in the background art, such as the relatively poor noise reduction effect of the existing expansion joint structure and the short service life of the rubber pad. Therefore, a noise-reducing expansion joint is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a noise-reducing expansion joint, comprising a steel structure, wherein a rubber pad is provided on the top of the steel structure, and a rubber strip assembly and a shock-absorbing assembly are provided on the surface of the steel structure;

[0006] The rubber strip assembly includes a T-slot, a screw hole, a T-shaped component, a rubber strip, a connector, and bolts;

[0008] Preferably, the T-slot is used for the insertion of the T-shaped member into its interior, and the T-slot and the T-shaped member in the engaged state are used to pre-limit the position of the rubber strip.

[0009] Preferably, the screw hole is used for threaded connection of the bolt, and the bolt in the tightened state is used to lock the position of the rubber strip.

[0012] The mounting plate is screwed into the groove of the steel structure, the spring is fixedly mounted on the surface of the mounting plate, and the support plate is fixedly connected to the end of the spring.

[0013] Preferably, the support plate is in contact with the surface of the rubber pad, and the spring cooperates with the support plate to provide shock absorption and cushioning for the rubber pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the rubber strip assembly has two rubber strips installed on both sides of the steel structure. The rubber strips installed on both sides of the steel structure can absorb vibration and impact energy, effectively improving the noise reduction effect of the steel structure.
