Description
Technical Field

[0002] Rubber seismic isolation bearings are seismic isolation devices used in building structures. They are located between the superstructure and the foundation. By adding a seismic isolation layer and installing rubber seismic isolation bearings, a soft connection with the ground is achieved, which significantly reduces the damage to the building structure caused by earthquakes and improves the safety performance of the building.
[0003] After searching, the announcement number is CN217997800U, and the name is a utility model of an adaptive shock-absorbing bridge sliding rubber bearing, which includes a rectangular bearing, an adjustment unit and a connecting unit. Through research and analysis, it is found that when a small angle of skew occurs during the installation of the device, the support angle position of the structure can be adjusted to reduce the workload, and the limiting structures on both sides of the rubber bearing can reduce the sliding and increase the support stability. However, the following disadvantages still exist to a certain extent.
[0004] For example, it can only buffer in the vertical direction, and is easily disturbed by torsional force during the buffering process, causing the device to shake to a certain extent during the up and down shock absorption process, thereby affecting the shock absorption effect. In addition, screw one and screw two are connected to the device through threads, and the installation stability is poor. After being vibrated, the screw is easy to move, which will cause the installation position to shift. In order to solve the above technical problems, we have designed a building seismic isolation device based on a rubber isolation layer. Utility Model Content
