Description

Technical Field

[0001] The utility model relates to the technical field of seismic isolation bearings, in particular to a vibration-reducing tension-compression seismic isolation bearing. Background Art

[0002] Seismic isolation bearings are an advanced technology used to reduce the vibration effects of building structures during earthquakes. They separate the upper structure of a building from its lower structure to reduce the transfer of seismic energy. Seismic isolation bearings are usually made of rubber and other materials and can absorb and disperse the energy generated by earthquakes, thereby protecting buildings from serious damage. During an earthquake, seismic isolation bearings will undergo large horizontal displacements to absorb a large amount of seismic energy, thereby significantly reducing the seismic response of the upper structure. In addition, seismic isolation bearings have high installation requirements and require precise control of their elevation and horizontality to ensure their normal operation and extend their service life.

[0003] The patent document with application number CN202320948486.6 discloses a seismic isolation bearing, which includes an upper connecting plate, a rubber seat and a lower connecting plate, wherein the rubber seat is fixedly connected to the bottom of the upper connecting plate, the lower connecting plate is fixedly connected to the bottom of the rubber seat, the top of the lower connecting plate is fixedly connected to a reversing box, the top of the reversing box is slidably connected to a sliding plate, both sides of the sliding plate are fixedly connected to support plates, one side of the support plate is fixedly connected to a support plate, the two ends of the support plate are respectively fixedly connected to the upper connecting plate and the lower connecting plate, and the sliding plate is internally slidably connected to a buffer mechanism. Based on the search of the above-mentioned patent and in combination with the seismic isolation bearings in the prior art, it is found that when the above-mentioned seismic isolation bearings are used, the existing vibration-damping tensile-compression seismic isolation bearings have long-term tensile-compression fatigue problems, resulting in performance degradation, especially the bearings may be excessively deformed under extreme conditions, and their internal structures are destroyed, and they will no longer be able to play the shock-absorbing and seismic isolation functions, and may even cause the houses supported by the bearings to collapse in a fault-like manner.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vibration-damping tension-compression seismic isolation bearing, comprising a first embedded rib, a first embedded steel plate is fixedly installed at the lower end of the first embedded rib, a second embedded steel plate is arranged below the first embedded steel plate, a second embedded rib is fixedly installed at the lower end of the second embedded steel plate, a seismic isolation mechanism and a limiting mechanism are arranged between the first embedded steel plate and the second embedded steel plate, the limiting mechanism comprises a spring body, a spring plate, a limiting steel sleeve and a fixed steel plate, and a limiting steel sleeve is arranged on the outer side of the seismic isolation mechanism.

[0006] Optionally, a spring body is fixedly mounted on the upper end of the second embedded steel plate, and four groups of the spring bodies are fixedly mounted on the upper end of the second embedded steel plate.

[0007] Optionally, a spring plate is fixedly mounted on the upper end of the spring body, and the limiting steel sleeve is fixedly mounted on the upper end of the spring plate.

[0008] Optionally, a fixed steel plate is fixedly installed on the upper end of the spring plate, and multiple groups of the fixed steel plates are evenly distributed on the outside of the limiting steel sleeve.

[0009] Optionally, the seismic isolation mechanism includes a glass fiber inner core, a steel plate cushion layer and a rubber cushion layer, and the glass fiber inner core is fixedly installed in the middle of the first embedded steel plate and the second embedded steel plate.

[0010] Optionally, a steel plate cushion layer and a rubber cushion layer are arranged on the outer side of the glass fiber inner core, and a plurality of groups of the steel plate cushion layers and the rubber cushion layers are distributed from top to bottom between the first embedded steel plate and the second embedded steel plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, a seismic isolation mechanism is provided. The seismic isolation mechanism adopts a combined structure of a glass fiber inner core, a steel plate cushion layer and a rubber cushion layer to form a multi-layer composite elastic shock-absorbing layer. This structure can effectively disperse stress, reduce fatigue damage and improve the durability of the support when subjected to tension and compression. The glass fiber inner core provides specific damping performance and mechanical strength, so that the seismic isolation mechanism can effectively absorb and disperse energy under earthquakes or other vibrations to protect the building from serious damage.

[0013] 2. In the utility model, a limiting mechanism is provided, and the limiting mechanism adopts a non-fixed structure, including a spring body, a spring plate, a limiting steel sleeve and a fixed steel plate. This structure will not affect the seismic isolation effect of the parts in the seismic isolation mechanism. At the same time, it plays a limiting role when the glass fiber and the laminated steel plate cushion layer and the rubber cushion layer in the seismic isolation mechanism are excessively stretched, thereby preventing the seismic isolation mechanism from excessive deformation. The limiting mechanism can play a limiting role when the seismic isolation mechanism is excessively deformed, preventing the support from excessive deformation, thereby ensuring the structural safety under extreme conditions, which helps to avoid damage to the internal structure of the support, ensure that the seismic isolation and shock absorption functions are maintained, and prevent the building from a fault-like collapse. The non-fixed structural design of the limiting mechanism ensures that the limiting mechanism will not have a negative impact on the seismic isolation effect during normal operation, and only plays a role when the glass fiber and the laminated steel plate cushion layer and the rubber cushion layer in the seismic isolation mechanism are excessively stretched, thereby improving the reliability of the support.
