Description

Technical Field

[0001] This utility model relates to the technical field of composite friction pendulum support, specifically a composite friction pendulum support. Background Technology

[0002] The composite friction pendulum bearing is a type of bearing that utilizes the pendulum principle to achieve seismic isolation and vibration reduction. It mainly achieves its seismic isolation function by consuming seismic energy through sliding interface friction and extending the natural period of the structure through spherical oscillation.

[0003] Conventional composite friction pendulum support structures employ a relatively closed structure, making maintenance between structures more cumbersome, time-consuming, and labor-intensive. Furthermore, due to the lack of proper structural support and restraint between the upper and lower structures caused by the frictional moving structure in the middle, there is a risk of misalignment. Utility Model Content

[0004] The purpose of this invention is to provide a composite friction pendulum support to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite friction pendulum support, comprising an upper friction support and a damping shock absorber column. A friction liner component is movably installed at the bottom center of the upper friction support, and a lower friction support is provided directly below the friction liner component. An upper buffer support is movably installed at the top of the upper friction support, and a lower buffer support is movably installed at the bottom of the lower friction support. The damping shock absorber column is symmetrically and vertically installed on the front and rear sides between the upper and lower buffer supports. The damping shock absorber column comprises a damping energy-absorbing column body, a damping hinge, and a fixing seat. Damping hinges are installed at both the upper and lower ends of the damping energy-absorbing column body, and a fixing seat is connected to the end of the damping hinge away from the damping energy-absorbing column body.

[0006] Furthermore, the upper friction support includes a buffer assembly, an upper base, an upper support plate, and an upper support corner plate. The upper base is provided on the side of the buffer assembly away from the friction liner component, and six sets of upper support plates are arranged in a circular array around the buffer assembly with the buffer assembly as the center. Moreover, six sets of upper support corner plates are arranged in a circular array around the buffer assembly with the buffer assembly as the center at the angle between the side of the upper base and the surface of the upper base.

[0007] Furthermore, the friction liner component includes a buffer seat, a mounting seat, an energy-absorbing seat, and a steel spherical liner. The bottom of the buffer seat is provided with a mounting seat, and the bottom of the mounting seat is provided with an energy-absorbing seat. The bottom of the energy-absorbing seat is also provided with a steel spherical liner.

[0008] Furthermore, the lower friction support includes a buffer friction seat, a lower base, a lower support plate, and a lower support corner plate. The lower base is provided on the side of the buffer friction seat away from the friction liner member, and the lower support plate is arranged in a ring array around the buffer friction seat at the edge of the lower base. Moreover, the lower support corner plate is arranged in a ring array around the buffer friction seat at the angle between the side of the buffer friction seat and the surface of the lower base.

[0009] Furthermore, the upper base, upper support plate, and upper support corner plate have the same structure as the lower base, lower support plate, and lower support corner plate, and the upper base and upper support plate are integrated into one structure.

[0010] Furthermore, the upper base and the upper support corner plate are welded together, and the lower base and the lower support plate are integrally formed, with the lower base and the lower support corner plate also welded together.

[0011] Furthermore, the upper buffer support includes a support body, anti-slip patterns, and limiting posts. One side surface of the support body is provided with an annular concentric circle structure of anti-slip patterns, and limiting posts are vertically provided at the four opposite corners of the support body.

[0012] Furthermore, the damping hinge and the fixed seat are welded together, and the damping hinge, the fixed seat and the support body are movably connected. The damping shock absorber column is symmetrically installed on one side between the upper buffer support and the lower buffer support, and the lower buffer support and the upper buffer support are integrally structured.

[0013] This utility model provides a composite friction pendulum support, which has the following beneficial effects:

[0014] 1. This utility model incorporates a damping shock absorber column. The entire damping shock absorber column is connected to the bottom surface of the upper buffer support and the top surface of the lower buffer support via fixed bases at both ends. This structural design of the damping shock absorber column serves two purposes: firstly, by connecting the upper and lower buffer supports, it ensures the overall structural stability of the device. Secondly, the extensibility of the damping energy-absorbing column itself provides structural assistance to the upper friction support, friction liner component, and lower friction support, absorbing and mitigating vibrations to improve the efficiency of the device. Furthermore, the symmetrical damping hinges at both ends of the damping energy-absorbing column prevent interference with the frictional movement between the upper friction support, friction liner component, and lower friction support, ensuring the effective operation of the device.

[0015] 2. This utility model, by setting up an upper buffer support and a lower buffer support, wherein the upper buffer support and the lower buffer support have the same structure, and by setting limit piles at the four opposite corners of the support body, combined with the anti-slip texture structure, ensures the assembly stability of the entire upper buffer support and the installation structure surface, thereby minimizing unnecessary offset problems and providing sufficient structural stability for the installation of the device. In addition, the upper friction support, friction liner component, lower friction support, upper buffer support, lower buffer support and damping column adopt a modular structure, which allows for relatively convenient structural installation or disassembly of each structure, facilitates structural maintenance, and ensures sufficient structural connection firmness to achieve sufficient energy absorption and vibration reduction.

The damping column 6 includes a damping energy-absorbing column body 601, a damping hinge 602, and a fixing seat 603. The damping hinge 602 is installed at both the upper and lower ends of the damping energy-absorbing column body 601, and the end of the damping hinge 602 away from the damping energy-absorbing column body 601 is connected to the fixing seat 603. The damping hinge 602 and the fixed seat 603 are welded together, and the damping hinge 602, the fixed seat 603 and the support body 401 are movably connected. The damping shock absorber column 6 is symmetrically installed on one side between the upper buffer support 4 and the lower buffer support 5, and the lower buffer support 5 and the upper buffer support 4 are integrated into one structure. The entire damping shock absorber column 6 is connected to the bottom surface of the upper buffer support 4 and the top surface of the lower buffer support 5 by the fixed seats 603 at both ends. The structure of the damping shock absorber column 6 can assist the upper friction support 1, the friction liner component 2 and the lower friction support 3 in generating an action, while providing a certain degree of structural assistance to absorb and mitigate vibration, so as to improve the efficiency of the device structure.

[0025] like Figures 1 to 6As shown, the upper friction support 1 includes a buffer assembly 101, an upper base 102, an upper support plate 103, and an upper support angle plate 104. The upper base 102 is provided on the side of the buffer assembly 101 away from the friction liner component 2, and six sets of upper support plates 103 are arranged in a circular array around the buffer assembly 101 at the edge of the upper base 102. Furthermore, six sets of upper support angle plates 104 are arranged in a circular array around the buffer assembly 101 at the angle between the side of the upper base 102 and the surface of the upper base 102. The friction liner component 2 includes a buffer seat 201 and a mounting seat 202. The buffer seat 201 includes an energy-absorbing base 203 and a steel spherical liner 204. The bottom of the buffer seat 201 is provided with a mounting base 202, and the bottom of the mounting base 202 is provided with an energy-absorbing base 203. The bottom of the energy-absorbing base 203 is also equipped with a steel spherical liner 204. The lower friction support 3 includes a buffer friction seat 301, a lower base 302, a lower support plate 303, and a lower support corner plate 304. The lower base 302 is located on the side of the buffer friction seat 301 away from the friction liner component 2, and the lower support plate 303 is arranged in a circular array around the buffer friction seat 301. Furthermore, at the angle between the side of the buffer friction seat 301 and the surface of the lower base 302, a ring array of lower support angle plates 304 is arranged with the buffer friction seat 301 as the center. The upper base 102, upper support plate 103, and upper support angle plate 104 have the same structure as the lower base 302, lower support plate 303, and lower support angle plate 304, respectively. The upper base 102 and upper support plate 103 are integrally formed, and the upper base 102 and upper support angle plate 104 are welded together. The lower base 302 and lower support plate 303 are also integrally formed. The corner plates 304 are welded together. The upper buffer support 4 includes a support body 401, anti-slip texture 402, and limiting post 403. One side surface of the support body 401 is provided with an annular concentric circle structure of anti-slip texture 402, and the four opposite corners of the support body 401 are vertically provided with limiting posts 403. By setting the limiting posts 403 at the four opposite corners of the support body 401, in conjunction with the structure of the anti-slip texture 402, the assembly stability of the entire upper buffer support 4, lower buffer support 5 and the installation structure surface is ensured, thereby minimizing unnecessary offset problems.

[0026] In summary, as Figures 1 to 6 As shown, when using this composite friction pendulum support, firstly, the energy-absorbing seat 203 with the steel spherical liner 204 installed on the entire bottom is fixed to the bottom of the buffer seat 201 using the mounting seat 202. Then, the entire friction liner component 2 is fixed to the bottom middle of the buffer assembly seat 101 using the structure of the buffer seat 201 and the use of bolts.

[0027] Then, the upper friction support 1, which is connected to the friction liner component 2, is fixed to the bottom surface of the upper buffer support 4 by using the upper base 102 connected to the upper friction support 1 and bolts. Next, the buffer friction seat 301 is fixed to the top surface of the lower buffer support 5 by using the lower base 302 connected to the lower support plate 303 and bolts.

[0028] Then, holes matching the structure of the limiting pile 403 are pre-drilled on the installation structure surface. With the use of bolts, the limiting piles 403 at the four opposite corners of the support body 401 are embedded into the installation structure surface and anchored. In this way, the upper buffer support 4, which is connected to the upper friction support 1 and the friction liner component 2, and the lower friction support 3, which is connected to the lower friction support 3, are respectively set up opposite each other.

[0029] Finally, the entire damping column 6 is fixedly connected to the bottom surface of the upper buffer support 4 and the top surface of the lower buffer support 5 using the fixing seat 603 at one end of the damping hinge 602 and bolts. This provides sufficient structural support and energy absorption and damping assistance between the upper buffer support 4 and the lower buffer support 5.
