Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a building seismic isolation device. Background Technology

[0002] Seismic isolation devices are used to isolate or dissipate seismic energy, reducing the impact of earthquakes on the superstructure of buildings. They are typically installed at the base of a building or at a specific location, forming an isolation layer that separates the superstructure from the foundation, thereby preventing or reducing the transmission of seismic energy to the upper structure. Seismic isolation devices can significantly reduce the degree of damage caused by earthquakes, ensuring the stability and safety of buildings during earthquakes. By isolating or dissipating seismic energy, they reduce the vibration and displacement of the superstructure, thus protecting the structural safety of the building.

[0003] During building construction, the foundation construction is carried out first. After excavating the foundation pit, leveling and compacting it, the installation position of the seismic isolation device is set and a groove or protrusion is reserved. The seismic isolation device is then placed in place, and after adjusting its position and posture, it is connected and fixed to the foundation and superstructure by means of connecting plates and bolts.

[0004] In existing technologies, some building seismic isolation devices can only provide a single seismic isolation effect during use, which makes them prone to deformation during the seismic isolation process, resulting in loss of seismic isolation effect and reduced service life. Therefore, in order to address the above shortcomings, a new building seismic isolation device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a building seismic isolation device, which aims to improve the problem that some existing building seismic isolation devices have a single seismic isolation effect, resulting in a reduced service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A seismic isolation device for buildings includes two connecting plates. A fixing plate is fixedly connected to one adjacent side of each connecting plate. A seismic isolation pad is fixedly connected to one adjacent side of each fixing plate. A damper is fixedly connected inside the seismic isolation pad. Fixing cylinders are fixedly connected around one adjacent side of each fixing plate. A support assembly is slidably connected inside each fixing cylinder. Two transmission plates are fixedly connected to the left and right sides of each support assembly. A force-bearing plate is slidably connected to the outside of each transmission plate. A fixing block is fixedly connected to the outside of each force-bearing plate. A positioning rod is slidably connected inside each of the two fixing blocks. A spring is sleeved on the outside of each positioning rod.

[0008] As a further description of the above technical solution:

[0009] One of the connecting plates is fixedly connected to a mounting block on its bottom side. Trapezoidal blocks are slidably connected to both ends of the mounting block. An open plate is fixedly connected to the adjacent side of the two trapezoidal blocks. Two rotating plates are rotatably connected inside the open plate. Two concave plates are rotatably connected to the adjacent ends of the multiple rotating plates. A spring is fixedly connected to the adjacent side of the two concave plates.

[0010] As a further description of the above technical solution:

[0011] Each of the aforementioned transmission components includes two sliding discs, the outer side of which is slidably connected to the inner wall of the fixed cylinder, a sliding column is fixedly connected to the adjacent side of each of the two sliding discs, and a fixed disc is fixedly connected to the adjacent side of each of the two sliding columns.

[0012] As a further description of the above technical solution:

[0013] The sliding disc is externally fixedly connected to one side of the two transmission plates, and the two force-bearing plates are externally slidably connected to the inside of the left and right ends of the fixed cylinder, respectively.

[0014] As a further description of the above technical solution:

[0015] The sliding column is slidably connected to the inner wall of the fixed cylinder, and the positioning rod is fixedly connected to the inner wall of the fixed cylinder.

[0016] As a further description of the above technical solution:

[0017] The two fixed blocks are fixedly connected to the left and right ends of the spring one on their adjacent sides, and the two fixed blocks are slidably connected to the inside of the fixed cylinder.

[0018] As a further description of the above technical solution:

[0019] One of the connecting plates is fixedly connected to a stone block on its bottom side by multiple bolts, and the outside of the mounting block is slidably connected to the inside of the stone block;

[0020] As a further description of the above technical solution:

[0021] The exteriors of the two concave plates are slidably connected to the interiors of the upper and lower ends of the mounting block, respectively, and the exteriors of the two trapezoidal blocks are slidably connected to the interiors of the left and right ends of the opening plate, respectively.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, two force-bearing plates slide towards each other and then compress the spring to store elastic potential energy, enabling it to absorb the force of vibration for the first time. At the same time, the fixing plate also squeezes the vibration isolation pad and the damper. The vibration isolation pad made of high-damping rubber can absorb more than 100% of the seismic energy through shear deformation. The damper with lead core rubber composite structure provides additional energy dissipation and controls displacement, thereby achieving a triple vibration isolation effect and extending its service life.

[0024] 2. In this utility model, the second spring can store elastic potential energy and then transfer the elastic force to the trapezoidal block. When the connecting plate and the stone block are completely attached, the force of the second spring returning to its original position is transferred to the two trapezoidal blocks to engage inside the stone block, thereby completing the initial installation, so as to facilitate subsequent welding or pouring, and thus improve the installation efficiency.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a building seismic isolation device, comprising two connecting plates 1, with fixed plates 2 fixedly connected to adjacent sides of the two connecting plates 1 by welding, so that the connecting plates 1 and fixed plates 2 can form an integral unit. A seismic isolation pad 3, made of high-damping rubber, is fixedly connected to adjacent sides of the two fixed plates 2, absorbing more than 80% of seismic energy through shear deformation. A damper 4, using a lead-core rubber composite structure, is fixedly connected inside the seismic isolation pad 3, providing additional energy dissipation and controlling the displacement of the isolation layer. A stone pier 5 is fixedly connected to the bottom side of one of the connecting plates 1 by multiple bolts, allowing the entire unit to be installed on the stone pier 5. Fixed cylinders 6 are fixedly connected to the perimeter of adjacent sides of the two fixed plates 2 by welding, thereby providing support for the fixed cylinders 6.

[0033] The fixed cylinder 6 has a support assembly internally slidably connected to it. Multiple transmission assemblies each include two sliding discs 7. The sliding discs 7 are externally slidably connected to the inner wall of the fixed cylinder 6, allowing them to slide stably. Sliding columns 8 are fixedly connected to adjacent sides of the two sliding discs 7 via welding, providing support for the columns 8. The sliding columns 8 are externally slidably connected to the inner wall of the fixed cylinder 6, allowing them to slide stably. A fixed disc 9 is fixedly connected to adjacent sides of the two sliding columns 8, forming a configuration of one fixed disc 9 paired with two sliding columns 8. Two transmission plates 10 are fixedly connected to both sides of the support assembly, driving the two connecting transmission plates 10 to slide. A force-bearing plate 11 is externally slidably connected to the transmission plate 10, transmitting the sliding force to the force-bearing plate 11 through the transmission plate 10.

[0034] Two force-bearing plates 11 are slidably connected to the left and right ends of the fixed cylinder 6, respectively. The fixed cylinder 6 restricts the force-bearing plates 11, allowing them to slide stably. Fixed blocks 12 are fixedly connected to the outside of each force-bearing plate 11, transmitting the sliding force to the fixed blocks 12. The two fixed blocks 12 are slidably connected to the inside of the fixed cylinder 6, again restricting their movement. Positioning rods 13 are slidably connected to the inside of each fixed block 12, guiding their sliding. The positioning rods 13 are fixedly connected to the inner wall of the fixed cylinder 6 via welding, providing stable support. A spring 14 is fitted over the positioning rod 13, ensuring it receives uniform force. Two fixed blocks 12 are fixedly connected to the left and right ends of the spring 14 on their adjacent sides. When the fixed blocks 12 slide, they compress the spring 14, which allows the spring 14 to store elastic potential energy and then give the fixed blocks 12 a force in the opposite direction.

[0035] Reference Figure 1 , Figure 2 and Figure 4 One of the connecting plates 1 has a mounting block 15 fixedly connected to its bottom side by welding, thus providing support for the mounting block 15. The mounting block 15 is externally slidably connected to the inside of the stone pier 5, and the stone pier 5 guides the mounting block 15 for easy installation. Trapezoidal blocks 16 are slidably connected to both ends of the mounting block 15, allowing them to slide stably. Two open plates 17 are externally slidably connected to the inside of both ends of the mounting block 15, allowing them to slide stably. Two adjacent sides of the two trapezoidal blocks 16 are fixedly connected to open plates 17, transmitting the sliding force to the open plates 17. Two rotating plates 18 are rotatably connected inside the open plates 17, transmitting the sliding force to the two connected rotating plates 18 for rotation. Two concave plates 19 are rotatably connected to adjacent ends of the multiple rotating plates 18, transmitting the rotational force to the concave plates 19 for sliding. The two concave plates 19 are slidably connected to the upper and lower ends of the mounting block 15, respectively. The mounting block 15 restricts the movement of the two concave plates 19, allowing them to slide stably. A second spring 20 is fixedly connected to the adjacent side of the two concave plates 19. By sliding the two concave plates 19 toward the adjacent side and compressing the second spring 20, the second spring 20 can store elastic potential energy, thereby applying a force in the opposite direction to the concave plates 19 to reset them.

[0036] Working principle: When vibration occurs, the connecting plate 1 and the fixed plate 2 transmit the vibration force to the fixed cylinder 6, which then drives the fixed cylinder 6 to guide the sliding column 8 to slide. Furthermore, the fixed cylinder 6 is restricted by the sliding disc 7, which allows the force plate 11 to push against the transmission plate 10, causing the two force plates 11 to slide towards each other. Then, the spring 14 is compressed to store elastic potential energy, enabling it to absorb the vibration force for the first time. At the same time, the fixed plate 2 also compresses the vibration isolation pad 3 and the damper 4. The vibration isolation pad 3, made of high-damping rubber, can absorb more than 100% of the seismic energy through shear deformation. The damper 4, with its lead core rubber composite structure, provides additional energy dissipation and controls displacement.

[0037] When installing one of the connecting plates 1 and the stone pier 5, the two trapezoidal blocks 16 slide towards each other, which in turn drives the open plate 17 to rotate. This, in turn, drives the two connected rotating plates 18 to rotate, which in turn drives the two concave plates 19 to slide towards each other and stretch the second spring 20. This allows the second spring 20 to store elastic potential energy and then transfer the elastic force to the trapezoidal blocks 16. When the connecting plate 1 and the stone pier 5 are fully fitted, the force of the second spring 20 returning to its original position is transferred to the two trapezoidal blocks 16, which are then engaged inside the stone pier 5. This completes the initial installation, which facilitates subsequent welding or pouring and improves installation efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
