Description

Technical Field

[0001] The utility model relates to the technical field of earthquake resistance, in particular to a new type of building earthquake-resistant bearing. Background Technique

[0002] Traditional earthquake resistance methods mainly rely on enhancing the structural strength of buildings, such as using thicker steel bars and more concrete, but the earthquake resistance effect of this method is not ideal. With the progress of technology, people have begun to explore more effective earthquake resistance technologies, and building earthquake-resistant bearings have emerged as the times require. Through its unique structure and material selection, such as the alternating lamination of rubber and steel plates, and damping materials such as lead cores that may be added, the building earthquake-resistant bearing realizes the effective absorption and dispersion of seismic energy. When an earthquake occurs, the earthquake-resistant bearing can deform, thereby absorbing the energy generated by the earthquake and reducing its transmission to the superstructure. This "soft connection" method significantly improves the earthquake resistance performance of buildings. Its advantages lie in being able to significantly reduce the damage degree of earthquakes to buildings and protect people's lives and property. At the same time, the earthquake-resistant bearing also has economy and practicability, and can significantly improve the earthquake resistance ability of buildings without significantly increasing the construction cost. The building earthquake-resistant bearing is one of the important achievements of modern earthquake resistance technology and plays an irreplaceable role in improving the earthquake resistance performance of buildings and ensuring people's lives and property safety.

[0003] For example, patent CN214195049U discloses a building earthquake-resistant bearing, belonging to the technical field of building engineering design. The building earthquake-resistant bearing includes a bottom plate, a baffle is fixedly connected to the upper surface of the bottom plate, a connecting rod is fixedly connected to one side of the baffle, a spring is movably connected to the surface of the connecting rod, one end of the spring is movably connected to a slider, a fixing block is fixedly connected to the upper surface of the slider, a rotating shaft is inserted in the middle of the fixing block, a support plate is fixedly connected to one side of the surface of the rotating shaft, the other end of the support plate is movably connected to a disc, and a top plate is fixedly connected to the upper surface of the disc. Through the settings of the sleeve, small spring, pressure plate, and support rod, the bearing can be more stable. When the top plate is shaken, the upper bearing plate can withstand the impact force from various angles, and the small spring, pressure plate, and support rod can weaken the impact force during an earthquake, achieving better safety and earthquake resistance ability.

[0004] When using the above technology, it is found that the following technical problems exist in the existing technology: Buildings usually have a large mass, and the shock absorption device needs to bear a large force. For an existing building earthquake-resistant bearing, using a spring for shock absorption and buffering has a not good enough effect. Since the spring may also have problems such as fatigue, relaxation, and corrosion during use, there is a certain room for improvement. Therefore, we design a new type of building earthquake-resistant bearing to provide another technical solution for the above technical problems. Content of the Utility Model

[0031] Embodiment 1

[0032] Referring to Figure 1 - Figure 6 , a new type of building seismic isolation bearing, comprising a lower mounting plate 1 and an upper mounting plate 2. The upper mounting plate 2 is assembled on the top of the lower mounting plate 1. A spherical bearing shock absorption mechanism is assembled between the lower mounting plate 1 and the upper mounting plate 2, and a seismic isolation bearing shock absorption mechanism is also assembled between the lower mounting plate 1 and the upper mounting plate 2;
