Technical Field

[0001] The invention belongs to the technical field of seismic isolation bearings, and in particular relates to a seismic isolation rubber bearing used in construction engineering. Background Art

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

[0003] Existing seismic isolation bearings usually directly use rubber columns and other structures to buffer the horizontal force. However, when the horizontal thrust is relatively large, the rubber column cannot withstand it and will be damaged, making the seismic isolation bearing unable to withstand a larger horizontal thrust. Therefore, how to provide a seismic isolation rubber bearing for construction engineering is a problem that technicians in this field need to solve urgently. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0027] In this embodiment, the top plate assembly includes a top plate 1 and a top pressure assembly. A slide groove 1.1 is provided on one side of the top plate 1. The top pressure assembly is slidably connected to the top plate 1 through the slide groove 1.1. The bottom end of the top pressure assembly abuts against the buffer assembly, and the top pressure assembly abuts against the extrusion assembly circumferentially.

[0028] In this embodiment, the top pressure assembly includes a first top block 2 and a second top block 3, the first top block 2 is provided with a connecting hole 2.2 and a secondary buffer groove 2.1, the bottom ends of the first top block 2 and the second top block 3 are abutted against the buffer assembly, and the second top block 3 is slidably connected to the first top block 2 through the connecting hole 2.2, and the same side of the first top block 2 and the second top block 3 is provided with a slider 4, and the slider 4 is slidably connected to the slide 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, such 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 the side where the second top block 3 abuts the buffer assembly, which can ensure the relative sliding of the first top block 2 and limit the second top block 3 at the same time.

[0029] In this embodiment, the extrusion assembly includes a first outer retaining ring 5 and a second outer retaining ring 6, and an extrusion block 7 is provided on the first outer retaining ring 5 and the second outer retaining ring 6. The extrusion block 7 is connected to the buffer assembly, and 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, and 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 arranged perpendicular to each other. 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, drive the extrusion block 7 to move, so that the extrusion block 7 applies pressure to the disc spring 8, and converts the horizontal thrust into a vertical force.

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

[0031] In this embodiment, the second elastic force-applying element is a rubber column, and may also be an element such as a spring that can apply elastic pressure, so as to improve the vertical buffering effect of the seismic isolation bearing, and 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 slide horizontally. When the first top block 2 and the second top block 3 slide horizontally, they push the first outer retaining ring 5 and the second outer retaining ring 6 to slide and expand outward from the outer center of the circle. At the same time, the extrusion block 7 slides and expands outward from the center of the circle. When expanding, the extrusion block 7 squeezes the disc springs 8 on both sides of the extrusion block 7, so that the horizontal force is changed into vertical pressure. At the same time, the disc springs and the second elastic force element are used for multiple buffering to improve the seismic isolation effect.
