Description

Technical Field

[0001] The present invention belongs to the technical field of seismic isolation bearings, and particularly relates to a seismic isolation rubber bearing for building engineering. Background Art

[0002] A seismic isolation bearing is a structure arranged at the bottom end of a building. When the building is affected by various factors such as earthquakes and typhoons, the building itself will be subjected to thrusts from various directions, and the seismic isolation bearing at the bottom end of the building is used to reduce the influence brought by the thrust itself and ensure the safety and stability of the building itself.

[0003] When the existing seismic isolation bearings are subjected to horizontal forces, they usually directly use structures such as rubber columns for buffering. However, when the horizontal thrust is relatively large, the rubber columns cannot bear it, which will cause the rubber columns to be damaged, making the seismic isolation bearings unable to bear greater horizontal thrust. Therefore, how to provide a seismic isolation rubber bearing for building engineering is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] The main purpose of the present invention is to provide a seismic isolation rubber bearing for building engineering to solve the above technical problems. The device is provided with a top plate assembly, an extrusion assembly and a buffer assembly. Through the mutual cooperation between the top plate assembly and the extrusion assembly, the thrust received by the seismic isolation bearing in the horizontal direction is converted into a vertical pressure, thereby pressing the buffer assembly and improving the thrust that the seismic isolation bearing can bear in the horizontal direction.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 - 9 shown, the present invention provides a seismic isolation rubber bearing for use in construction engineering, including a top plate assembly, an extrusion assembly, and a buffer assembly. A buffer assembly and an extrusion assembly are arranged between two said top plate assemblies. The extrusion assembly is sleeved on the buffer assembly, and the extrusion assembly cooperates with the buffer assembly to convert a horizontal thrust into a vertical thrust.

[0027] In this embodiment, the top plate assembly includes a top plate 1 and a top pressing component. A sliding groove 1.1 is arranged on one side of the top plate 1. The top pressing component is slidably connected to the top plate 1 through the sliding groove 1.1. The bottom end of the top pressing component abuts against the buffer assembly, and the circumferential direction of the top pressing component abuts against the extrusion assembly.

[0028] In this embodiment, the top pressing component includes a first top block 2 and a second top block 3. A connecting hole 2.2 and a secondary buffer groove 2.1 are arranged on the first top block 2. The bottom ends of the first top block 2 and the second top block 3 abut against the buffer assembly. The second top block 3 is slidably connected to the first top block 2 through the connecting hole 2.2. Sliders 4 are arranged on the same side of the first top block 2 and the second top block 3. The sliders 4 are slidably connected to the sliding groove 1.1; the connecting hole 2.2 is used to ensure the mutual sliding between the first top block 2 and the second top block 3. As Figure 4As shown, the width of the connecting hole 2.2 is greater than the width of the second top block 3, which is used to ensure that the second top block 3 can move within a certain range. Only two blocking blocks are provided on one side of the second top block 3 that abuts against the buffer assembly, which can ensure the relative sliding of the first top block 2 while restricting the second top block 3.

[0029] In this embodiment, the extrusion assembly includes a first outer retaining ring 5 and a second outer retaining ring 6. Extrusion blocks 7 are provided on both the first outer retaining ring 5 and the second outer retaining ring 6. The extrusion blocks 7 are connected to the buffer assembly. The two first outer retaining rings 5 are correspondingly sleeved on the outer walls of the first top block 2 and the second top block 3. The two second outer retaining rings 6 are correspondingly sleeved on the outer walls of the two first outer retaining rings 5. The extrusion blocks on the first outer retaining ring 5 and the second outer retaining ring 6 are perpendicularly arranged. When the first outer retaining ring 5 and the second outer retaining ring 6 are pressed by the first top block or the second top block 3, they will expand outward, driving the extrusion blocks 7 to move, so that the extrusion blocks 7 exert pressure on the disc spring 8, converting the horizontal thrust into a vertical force.

[0030] In this embodiment, the buffer assembly includes disc springs 8 and a second elastic force - applying element. A plurality of the disc springs 8 are correspondingly arranged on both sides of the extrusion blocks 7 inside the extrusion assembly. The directions of the disc springs 8 on the same side are the same. A second elastic force - applying element is provided at the center of the disc springs 8. A plurality of the disc springs 8 are sleeved on the second elastic force - applying element. The two ends of the second elastic force - applying element are respectively abutted against the secondary buffer grooves 2.1 on the two ends of the constant - pressure assembly. The disc springs 8 and the second elastic force - applying element perform multi - layer buffering on the vertical - direction pressure to improve the buffering effect of the seismic isolation bearing; the secondary buffer grooves 2.1 can prevent the first top block 2 from driving the second elastic force - applying element to move.

[0031] In this embodiment, the second elastic force - applying element is a rubber column, and it can also be an element such as a spring that can perform elastic pressure application, which is used to improve the buffering effect of the seismic isolation bearing in the vertical direction. The first elastic force - applying element is a disc spring.

[0032] Working principle: After the seismic isolation bearing is installed, when the seismic isolation bearing is subjected to a horizontal thrust, the horizontal thrust pushes the first top block 2 or the second top block 3 to perform horizontal sliding. When the first top block 2 and the second top block 3 perform horizontal sliding, they push the first outer retaining ring 5 and the second outer retaining ring 6 to slide and expand outward towards the outer center of the circle. At the same time, the extrusion blocks 7 slide and expand towards the outer side of the center of the circle. When the extrusion blocks 7 expand, they squeeze the disc springs 8 on both sides of the extrusion blocks 7, so that the horizontal thrust is changed into a vertical pressure. At the same time, multiple buffering is carried out by using the disc springs and the second elastic force - applying element to improve the seismic isolation effect.
