Abstract
Description
Technical Field
[0001] This utility model relates to the field of seismic isolation bearing technology, and in particular to a seismic isolation bearing correction device suitable for high-intensity seismic fortification areas. Background Technology
[0002] Seismic isolation bearings are special structural devices that, through their unique design and working principle, can effectively isolate the direct impact of seismic waves on buildings, thereby greatly reducing the damage caused by earthquakes.
[0003] In existing technologies, in some high-rise buildings, ultra-long span, large span, and seismic isolation buildings in cold and high-altitude regions, the large temperature difference and significant temperature deformation of ultra-long concrete structures cause large horizontal displacement of the seismic isolation bearings. This results in the bearings being under abnormal eccentric compression for extended periods, weakening their horizontal deformation capacity and seriously threatening the safety performance of the concrete structure. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a seismic isolation bearing correction device suitable for high-intensity seismic fortification areas.
[0005] This utility model is achieved using the following technical solution: a seismic isolation bearing correction device suitable for high-intensity seismic fortification areas, comprising a lower flange plate, a lower pre-embedded component fixedly connected inside the lower flange plate, an elastic body fixedly connected to the top of the lower flange plate, an upper flange plate fixedly connected to the end of the elastic body away from the lower flange plate, an avoidance groove and an offset groove formed inside the upper flange plate, a limit column fixedly connected to the inner wall of the offset groove, an upper top plate provided at the top of the upper flange plate, an offset groove one formed at the bottom of the upper top plate, an upper pre-embedded component fixedly connected inside the upper top plate, an upper pre-embedded component one fixedly connected inside the upper top plate, a corner guard fixedly connected to the bottom of the upper pre-embedded component, a bolt slidably connected inside the corner guard, and the bolt threadedly connected inside the upper flange plate.
[0006] As a further improvement to the above solution, several lower pre-embedded components are provided, and the several lower pre-embedded components are evenly distributed at the four corners of the lower flange plate. Several corner guards are provided, and four corner guards are provided, with the four corner guards evenly distributed at the four corners of the top plate above the four corner guards.
[0007] The above technical solution involves fixing an elastomer to the top of the lower flange plate and a limiting post to the inner wall of the upper flange plate. An offset is pre-defined between the limiting post and the upper flange plate. By adjusting the screwing position of the bolts, the bolts push against the corner guard, and the bolts are threaded onto the upper flange plate. The upper flange plate moves horizontally until it completely overlaps with the lower flange plate in the horizontal direction. The corner guard ensures that the upper flange plate does not exceed the pre-defined offset when it returns to its horizontal position, thereby eliminating the horizontal deformation of the elastomer and restoring the horizontal deformation capacity of the seismic isolation bearing. This solves the problem of the impact of excessive temperature changes on seismic isolation bearings in ultra-long, large-span, cold, and high-altitude regions. When the seismic isolation bearing shifts horizontally, it can recover its deformation, improving its deformation capacity and extending its service life. Furthermore, the structure is simple and easy to implement.
[0008] As a further improvement to the above solution, a fireproof plate is fixedly connected to the top of the lower flange plate, and a reinforcing rib is fixedly connected to the top of the lower flange plate.
[0009] By using the above technical solution, a fireproof board is fixed to the top of the lower flange plate, and the fireproof board is filled with fireproof cotton, which can prevent damage to the elastomer and protect the safety of the elastomer.
[0010] As a further improvement to the above solution, a support plate is fixedly connected to the outer wall of the rib, and the support plate is fixedly connected to the top of the lower flange plate.
[0011] As a further improvement to the above solution, a sliding rod is slidably connected inside the support plate, and a limit post is fixedly connected to one end of the sliding rod near the support plate.
[0012] As a further improvement to the above solution, a buffer plate is fixedly connected to the outer wall of the end of the sliding rod away from the limiting post.
[0013] As a further improvement to the above solution, a buffer spring is slidably connected to the outer wall of the sliding rod, and four buffer springs are provided, which are symmetrically arranged at the center of the lower flange plate.
[0014] Through the above technical solution, a rib is fixed on the top of the lower flange plate. The rib is fixed to the support plate and supports the support plate. A sliding rod slides inside the support plate. The sliding rod is fixed to the buffer plate and the limiting post. When the buffer plate is hit by a collision, the buffer plate squeezes the buffer spring. The buffer spring buffers the external force and prevents direct damage to the elastomer. It also prevents the elastomer from deforming, cracking or being damaged due to excessive impact force, thus extending its service life.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention fixes an elastomer to the top of the lower flange plate and a limiting post to the inner wall of the upper flange plate, with a pre-set offset between the limiting post and the upper flange plate. By adjusting the screw-in position of the bolts, the bolts push against the corner guard, and the bolts are threadedly connected to the upper flange plate. The upper flange plate moves horizontally until it completely overlaps with the lower flange plate in the horizontal direction. The corner guard ensures that the upper flange plate does not exceed the pre-set offset when it returns to its horizontal position, thereby eliminating the horizontal deformation of the elastomer and restoring the horizontal deformation capacity of the seismic isolation bearing. This solves the problem of the impact of excessive temperature changes on seismic isolation bearings in ultra-long, large-span, cold, and high-altitude regions. When the seismic isolation bearing shifts horizontally, it can recover its deformation, improving the deformation capacity of the seismic isolation bearing, extending its service life, and the structure is simple and easy to implement.
[0017] This utility model features a rib fixed to the top of the lower flange plate, which is fixed to the support plate and supports the support plate. A sliding rod slides inside the support plate, and the sliding rod is simultaneously fixed to the buffer plate and the limiting post. When the buffer plate is impacted, the buffer plate compresses the buffer spring, which buffers the external force and prevents direct damage to the elastomer. This prevents the elastomer from deforming, cracking, or being damaged due to excessive impact, thus extending its service life. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Example:
[0027] Please combine Figure 1-5 This embodiment discloses a seismic isolation bearing correction device applicable to high-intensity seismic fortification areas, comprising a lower flange plate 1, a lower pre-embedded component 2 fixedly connected inside the lower flange plate 1, an elastic body 3 fixedly connected to the top of the lower flange plate 1, an upper flange plate 4 fixedly connected to the end of the elastic body 3 away from the lower flange plate 1, an avoidance groove 5 and an offset groove 6 opened inside the upper flange plate 4, a limit column 7 fixedly connected to the inner wall of the offset groove 6, an upper top plate 8 provided at the top of the upper flange plate 4, an offset groove 9 opened at the bottom of the upper top plate 8, an upper pre-embedded component 10 and an upper pre-embedded component 11 fixedly connected inside the upper top plate 8, a corner guard 12 fixedly connected to the bottom of the upper pre-embedded component 10, a bolt 13 slidably connected inside the corner guard 12, and the bolt 13 threadedly connected inside the upper flange plate 4.
[0028] There are several lower embedded components 2, and the flange plates 1 below the several lower embedded components 2 are evenly distributed at the four corners. There are several corner guards 12, and four corner guards 12 are evenly distributed at the four corners of the top plate 8 above the four corner guards 12.
[0029] A fireproof plate 14 is fixedly connected to the top of the lower flange plate 1, and a reinforcing bar 15 is fixedly connected to the top of the lower flange plate 1.
[0030] A support plate 16 is fixedly connected to the outer wall of the rib 15, and the support plate 16 is fixedly connected to the top of the lower flange plate 1.
[0031] A sliding rod 17 is slidably connected inside the support plate 16, and a limit post 18 is fixedly connected to one end of the sliding rod 17 near the support plate 16.
[0032] A buffer plate 19 is fixedly connected to the outer wall of the end of the sliding rod 17 away from the limiting post 18.
[0033] The outer wall of the sliding rod 17 is slidably connected to a buffer spring 20. There are four buffer springs 20, and the four buffer springs 20 are symmetrically arranged on the flange plate 1 below the center.
[0034] The implementation principle of a seismic isolation bearing correction device applicable to high-intensity fortification areas in this application embodiment is as follows: The lower pre-embedded component 2 is fixed inside the lower concrete column; the upper pre-embedded component 10 and upper pre-embedded component 11 are fixed inside the upper concrete column; an elastic body 3 is fixed to the top of the lower flange plate 1, and simultaneously, the elastic body 3 is fixed to the upper flange plate 4; an offset groove 6 is opened on the top of the upper flange plate 4; an offset groove 9 is opened on the inner wall of the upper top plate 8; a limiting column 7 is fixed to the inner wall of the upper flange plate 4; and the limiting column 7 is fixed to the upper flange plate 4. An offset is reserved between them. By adjusting the screwing position of bolt 13, bolt 13 pushes against corner guard 12. At the same time, bolt 13 is threadedly connected to upper flange plate 4, so that upper flange plate 4 moves horizontally until it completely overlaps with lower flange plate 1 in the horizontal direction. Corner guard 12 protects upper flange plate 4 from not exceeding the reserved offset when it is horizontally reset, thereby eliminating the horizontal deformation of elastic body 3, that is, restoring the horizontal deformation capacity of seismic isolation bearing, and solving the impact of excessive temperature changes on seismic isolation bearing in ultra-long, large-span, cold, and high-altitude areas. When the seismic isolation bearing shifts horizontally, it can recover its deformation, improve its deformation capacity, and extend its service life. The structure is simple and easy to implement. A fireproof plate 14 is fixed to the top of the lower flange plate 1, and the fireproof plate 14 is filled with fireproof cotton to prevent damage to the elastomer 3 and protect its safety. Simultaneously, a reinforcing rib 15 is fixed to the top of the lower flange plate 1, and the reinforcing rib 15 is fixed to the support plate 16, providing support for the support plate 16. A sliding rod 17 slides inside the support plate 16, and the sliding rod 17 is simultaneously fixed to the buffer plate 19 and the limiting post 18. When the buffer plate 19 is impacted, it compresses the buffer spring 20, which buffers the external force, preventing direct damage to the elastomer 3 and preventing deformation, cracking, or damage to the elastomer 3 due to excessive impact, thus extending its service life.
[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
