Anti-shearing shock insulation support

Abstract

The utility model discloses an anti-shearing shock insulation support, and relates to the technical field of building shock insulation. The device comprises two groups of transverse guide rail assemblies embedded in a building body, damping rods are fixedly mounted on the inner walls of the two sides of each transverse guide rail assembly respectively, reset springs are arranged on the surfaces of the damping rods in a sleeving manner, and anti-pulling mounting sliding seats are mounted at the free ends of the damping rods. The anti-pulling installation sliding seat transversely moves on the surface of the transverse guide rail assembly so as to compress the damping rod and the reset spring, and force generated by earthquake horizontal vibration waves is absorbed under the action of damping force of the damping rod and elastic force of the reset spring. The shear force generated when the shock insulation rubber seat body deforms is reduced, the shock insulation rubber seat body is prevented from being damaged due to the fact that the shear force is too large, and force in a three-dimensional space can be absorbed through the two transverse guide rail assemblies arranged in a staggered mode and the shock insulation rubber seat body.

Description

Technical Field

[0001] This utility model relates to the field of building seismic isolation technology, specifically to a shear-resistant seismic isolation bearing. Background Technology

[0002] Seismic isolation bearings are one of the most widely used seismic isolation devices. They can extend the natural period of a structure, thereby avoiding the dominant period of a seismic site and reducing seismic damage to the structure. Their effectiveness has been verified by actual engineering projects.

[0003] Chinese Patent No. CN217439231U discloses a torsion-resistant liftable seismic isolation bearing, which includes: a seismic isolation body, an upper connecting plate fixedly disposed on the top of the seismic isolation body, and a lower connecting plate fixedly disposed on the bottom of the seismic isolation body;

[0004] Regarding the aforementioned disclosed technologies, in some near-field ground motions, the amplitude of vertical seismic action even exceeds that of horizontal seismic action. Vertical seismic action can also cause serious damage to engineering structures. Larger horizontal forces can cause horizontal displacement of vertical isolation devices, thereby subjecting the isolation devices to larger shear forces, which may affect the stability of the vertical isolation devices and thus easily lead to tensile failure of the supports. Utility Model Content

[0005] The purpose of this utility model is to provide a shear isolation bearing to address the aforementioned problems.

[0006] The technical solution of this utility model is as follows:

[0007] A shear isolation bearing includes two sets of transverse guide rail assemblies embedded in the building body. Damping rods are fixedly installed on the inner walls of both ends of the transverse guide rail assemblies, and return springs are sleeved on the surface of the damping rods. Pull-out mounting sliding seats are installed on the free ends of the damping rods, and the pull-out mounting sliding seats are slidably disposed on the surface of the transverse guide rail assemblies. A mounting seat is installed on the top surface of the pull-out mounting sliding seat, and a seismic isolation rubber seat body is provided on the end face of the mounting seat. Fixing bolts are threaded into the top surface of the seismic isolation rubber seat body and the end face of the mounting seat. Rubber protective sleeves are fixedly installed on the opposite surfaces of the two sets of mounting seats.

[0008] Furthermore, the transverse guide rail assembly includes a guide rail body, which is embedded in the building body. Guide and limiting grooves are respectively opened on both sides of the guide rail body, and a groove is opened on the end face of the guide rail body. Two sets of damping rods are fixedly installed on both sides of the groove.

[0009] Furthermore, the pull-out resistant mounting sliding seat includes a pull-out resistant frame. The pull-out resistant frame is slidably mounted on the surface of the guide rail body through a guide limiting groove. A protrusion is fixedly mounted on the inner wall of the pull-out resistant frame, and the protrusion and the groove are installed in an interlocking manner.

[0010] Furthermore, a threaded post is fixedly installed on the top surface of the pull-out bracket, and a mounting base is fixedly installed on the top end of the threaded post by a nut.

[0011] Furthermore, the mounting base includes a mounting plate, the end face of the pull-out bracket is fixedly mounted with the mounting plate by a protrusion and a threaded post, the end face of the mounting plate is fixedly mounted with a limit ring, and the top surface of the mounting plate is provided with a threaded hole.

[0012] Furthermore, a vibration-damping rubber seat body is inserted and installed on the end face of the mounting plate and inside the limiting ring, and a fixing bolt is inserted into the surface of the vibration-damping rubber seat body and the internal thread of the threaded hole, and a rubber protective sleeve is fixedly installed on the end face of the limiting ring.

[0013] Furthermore, the guide limiting groove is L-shaped, and the anti-pull-out frame is U-shaped overall, with both ends of the anti-pull-out frame being L-shaped, and both ends of the anti-pull-out frame being located in the guide limiting groove on the surface of the guide rail body.

[0014] Furthermore, the vibration-damping rubber seat body is located inside the rubber protective sleeve.

[0015] Furthermore, the rubber protective sleeve is made of elastic rubber material.

[0016] Furthermore, the surface of the rubber protective sleeve is coated with a corrosion-resistant coating.

[0017] Compared with existing technologies, the beneficial effects of this utility model are:

[0018] A shear-resistant seismic isolation bearing is disclosed. An anti-pull-out sliding seat is used to fix the mounting base. The isolation rubber bearing body is connected and fixed to the mounting base via fixing bolts. During an earthquake, the horizontal vibration force causes the isolation rubber bearing body and rubber protective sleeve to undergo horizontal deformation. Simultaneously, the isolation rubber bearing body drives the mounting base and the anti-pull-out sliding seat to move laterally on the surface of the transverse guide rail assembly. This lateral movement of the anti-pull-out sliding seat on the transverse guide rail assembly compresses the damping rod and the return spring. The damping force of the damping rod and the elastic force of the return spring absorb the force generated by the horizontal seismic wave, thereby reducing the shear force during the deformation of the isolation rubber bearing body. This prevents damage to the isolation rubber bearing body due to excessive shear force. The two sets of staggered transverse guide rail assemblies and the isolation rubber bearing body enable the absorption of forces in three-dimensional space. Attached Figure Description

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0025] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0026] Please see Figure 1-4A shear isolation bearing includes two sets of transverse guide rail assemblies 1 pre-embedded in the building body. Damping rods 2 are fixedly installed on the inner walls of both ends of the transverse guide rail assemblies 1, and return springs 3 are sleeved on the surface of the damping rods 2. Pull-out mounting sliding seats 4 are installed on the free ends of the damping rods 2, and the pull-out mounting sliding seats 4 are slidably disposed on the surface of the transverse guide rail assemblies 1. Mounting seats 5 are installed on the top surface of the pull-out mounting sliding seats 4, and a seismic isolation rubber seat body 6 is provided on the end face of the mounting seat 5. Fixing bolts 7 are threadedly inserted into the top surface of the seismic isolation rubber seat body 6 and the end face of the mounting seat 5. Rubber protective sleeves 8 are fixedly installed on the opposite surfaces of the two sets of mounting seats 5. Specifically, during building construction, the transverse guide rail assemblies 1 are pre-embedded in the building body, and the mounting seats 5 are fixed by the pull-out mounting sliding seats 4. The seismic isolation rubber seats 5 are then fixed by the fixing bolts 7. The main body 6 is connected and fixed to the mounting base 5. When the horizontal vibration force during an earthquake causes the seismic isolation rubber base 6 and the rubber protective sleeve 8 to undergo horizontal deformation, the seismic isolation rubber base 6 drives the mounting base 5 and the anti-pull-out mounting sliding seat 4 to move laterally on the surface of the transverse guide rail assembly 1. The transverse movement of the anti-pull-out mounting sliding seat 4 on the surface of the transverse guide rail assembly 1 compresses the damping rod 2 and the return spring 3. Under the action of the damping force of the damping rod 2 and the elastic force of the return spring 3, the force generated by the horizontal seismic vibration wave is absorbed, thereby reducing the shear force when the seismic isolation rubber base 6 deforms, thus preventing the seismic isolation rubber base 6 from being damaged due to excessive shear force. The two sets of staggered transverse guide rail assemblies 1 and the seismic isolation rubber base 6 can absorb the force in three-dimensional space.

[0027] like Figure 1 , Figure 2 , Figure 4 As shown, the transverse guide rail assembly 1 includes a guide rail body 101, which is embedded in the building body. Guide limiting grooves 102 are respectively opened on the two side walls of the guide rail body 101, and a groove 103 is opened on the end face of the guide rail body 101. Two sets of damping rods 2 are fixedly installed on the two side walls of the groove 103. Specifically, through the guide rail body 101 and the building pre-embedded, and through the guide limiting grooves 102 and grooves 103 on the surface of the guide rail body 101, the transverse displacement is guided and limited.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the pull-out resistant mounting sliding seat 4 includes a pull-out resistant frame 401. The pull-out resistant frame 401 is slidably mounted on the surface of the guide rail body 101 through the guide limiting groove 102. A protrusion 402 is fixedly mounted on the inner wall of the pull-out resistant frame 401, and the protrusion 402 and the groove 103 are installed in an interlocking manner. A threaded post 403 is fixedly mounted on the top surface of the pull-out resistant frame 401, and a mounting seat 5 is fixedly mounted on the top of the threaded post 403 through a nut 404. Specifically, the threaded post 403 and the nut 404 engage to achieve a fixed connection between the pull-out resistant frame 401 and the guide limiting groove 102, thereby achieving vertical pull-out resistance.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the mounting base 5 includes a mounting plate 501. The end face of the anti-pull-out bracket 401 is fixedly mounted with the mounting plate 501 via a protrusion 402 and a threaded post 403. A limit ring 502 is fixedly mounted on the end face of the mounting plate 501. A threaded hole 503 is provided on the top surface of the mounting plate 501. A vibration isolation rubber seat body 6 is inserted into the end face of the mounting plate 501 and inside the limit ring 502. A fixing bolt 7 is threadedly inserted into the surface of the vibration isolation rubber seat body 6 and the inside of the threaded hole 503. A rubber protective sleeve 8 is fixedly mounted on the end face of the limit ring 502. Specifically, the limit ring 502 limits the installation of the vibration isolation rubber seat body 6, and the fixing bolt 7 engages with the surface of the vibration isolation rubber seat body 6 and the inside of the threaded hole 503 to fix the vibration isolation rubber seat body 6.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the guide limiting groove 102 is L-shaped, and the anti-pull-out bracket 401 is U-shaped overall, with both ends of the anti-pull-out bracket 401 being L-shaped. The two ends of the anti-pull-out bracket 401 are respectively located in the guide limiting groove 102 on the surface of the guide rail body 101. Specifically, the anti-pull-out bracket 401 with a U-shaped structure and L-shaped ends engages with the guide limiting groove 102 on the surface of the guide rail body 101, thereby enabling lateral sliding and simultaneously improving the vertical anti-pull-out capability.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, the vibration isolation rubber seat body 6 is located inside the rubber protective sleeve 8, and the rubber protective sleeve 8 is made of elastic rubber material, and the surface of the rubber protective sleeve 8 is coated with a corrosion-resistant coating; specifically, the rubber protective sleeve 8 protects the vibration isolation rubber seat body 6 inside, thereby preventing the vibration isolation rubber seat body 6 from oxidizing and improving its service life.

[0032] In summary: The anti-pull-out sliding seat 4 fixes the mounting seat 5, and the fixing bolts 7 connect and fix the seismic isolation rubber seat body 6 to the mounting seat 5. When the horizontal vibration force during an earthquake causes the seismic isolation rubber seat body 6 and the rubber protective sleeve 8 to undergo horizontal deformation, the seismic isolation rubber seat body 6 drives the mounting seat 5 and the anti-pull-out sliding seat 4 to move laterally on the surface of the transverse guide rail assembly 1. The lateral movement of the anti-pull-out sliding seat 4 on the surface of the transverse guide rail assembly 1 compresses the damping rod 2 and the return spring 3. The damping force of the damping rod 2 and the elastic force of the return spring 3 absorb the force generated by the horizontal seismic vibration wave, thereby reducing the shear force when the seismic isolation rubber seat body 6 deforms, preventing the seismic isolation rubber seat body 6 from being damaged due to excessive shear force. The two sets of staggered transverse guide rail assemblies 1 and the seismic isolation rubber seat body 6 can absorb the force in three-dimensional space.

[0033] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
