Technical Field
[0001] This utility model relates to the field of friction pendulum support technology, specifically a friction pendulum support that is easy to assemble. Background Technology
[0002] Bridges, as vital transportation carriers, play a significant role in modern society's production and daily life. In recent years, with the increasing frequency of earthquakes, bridge damage from earthquakes has become commonplace. Earthquakes not only damage the bridge structure itself but also frequently cause secondary disasters. Friction pendulum bearings are crucial components connecting the bridge deck and piers. When no earthquake occurs, they support the bridge; during an earthquake, they also function as seismic isolation bearings, reducing the impact of earthquakes on bridges, minimizing damage, and ensuring the safety of lives. Friction pendulum bearings are a type of bearing used in engineering. Their main function is to dissipate horizontal forces on the support points of buildings or bridges through friction, thereby ensuring overall stability. However, existing friction pendulum bearings still have the following shortcomings:
[0003] When using existing friction pendulum supports, most of them require multiple bolts for fixed assembly and lack limiting structures during installation. This makes the installation of friction pendulum supports relatively time-consuming and labor-intensive, increasing the intensity of manual labor and causing a decrease in the practicality and efficiency of friction pendulum supports.

[0009] Furthermore, the internal dimensions of the receiving groove are adapted to the external dimensions of the mounting block, and the mounting block is embeddedly connected to the lower base plate through the receiving groove.
[0010] Furthermore, the friction assembly includes an upper seat plate, a fixing block, and anchor bolt holes. The upper seat plate has a fixing block at its outer upper end, and the fixing block has anchor bolt holes inside.
[0011] Furthermore, the friction assembly also includes an upper spherical support, an upper sliding friction surface, and a spherical crown plate body.
