Description

Technical Field

[0001] This utility model relates to the field of seismic isolation bearings, and more specifically, to a seismic isolation bearing and its installation structure. Background Technology

[0002] Seismic isolation bearings are support devices installed on structures to meet seismic isolation requirements. They are used to add a seismic isolation layer between the superstructure and the foundation. Installing seismic isolation bearings provides a soft connection with the ground. This technology can offset most of the seismic force and protect the superstructure.

[0003] A search revealed an existing patent (publication number: CN 219411349 U) that discloses a seismic isolation bearing, comprising an upper top plate, a rubber protective layer, a seismic isolation rubber pad, a core material, tie rod anchor plates, and tie rod holes. The corresponding surfaces of the upper top plate and lower bottom plate are connected to the rubber protective layer as a whole through vulcanization. The upper top plate and lower bottom plate have concave countersunk holes at the corresponding core material positions for tie rod tensioning, and bolt holes and tie rod holes are provided around the perimeter for connecting embedded parts and anchor bars. The core material is cylindrical with one end enlarged. The size of the cylindrical core material is determined according to the damping force design, and bolt holes are provided at the other end of the core material for fixing to the tie rod anchor plates with bolts. This seismic isolation bearing improves the core material utilization efficiency without changing the vulcanization bonding of the seismic isolation rubber pad. By changing the shape of the core material and enlarging both ends, the core material is anchored to the upper top plate and lower bottom plate of the bearing through the two ends of the core plate, thereby significantly improving the tensile strength of the seismic isolation device.

[0004] When existing seismic isolation bearings and installation structures are in use, the energy dissipation capacity of the seismic isolation bearings under seismic action is limited, and they cannot effectively reduce the transmission of seismic energy to the upper structure, resulting in certain limitations in their use. At the same time, the patent documents cited above do not propose any solutions to solve the above problems.

[0005] Therefore, a seismic isolation bearing and its installation structure are proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a seismic isolation bearing and installation structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a seismic isolation bearing and installation structure, comprising a lower connecting steel plate, wherein an energy dissipation component is provided at the upper end of the lower connecting steel plate, the energy dissipation component comprising a first energy dissipation layer, a second energy dissipation layer is fixedly disposed on one side of the first energy dissipation layer, and a third energy dissipation layer is fixedly adhered to one side of the second energy dissipation layer.

[0008] Preferably, the first energy-dissipating layer is made of polytetrafluoroethylene, the second energy-dissipating layer is made of graphite, and the third energy-dissipating layer is made of copper alloy.

[0009] Preferably, an intermediate steel plate is provided at the upper end of the lower connecting steel plate, and an upper connecting steel plate is provided at the upper end of the intermediate steel plate.

[0010] Preferably, a buffer assembly is provided between the upper connecting steel plate and the intermediate steel plate. The buffer assembly includes a first buffer layer, a second buffer layer is fixedly adhered to one side of the first buffer layer, and a third buffer layer is fixedly provided to one side of the second buffer layer.

[0011] Preferably, the first buffer layer is made of rubber material, the second buffer layer is made of polyurethane foam material, and the third buffer layer is made of metal spring material.

[0012] Preferably, the lower connecting steel plate, the middle steel plate, and the upper connecting steel plate are all connected by steel strands through through holes, and mounting seats are symmetrically arranged at both ends of the lower connecting steel plate.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this seismic isolation bearing and installation structure, through the setting of energy-dissipating components, uses three sets of energy-dissipating layers in combination. Through friction, it can convert seismic energy into heat energy, thereby reducing the seismic energy transmitted to the upper structure of the building. At the same time, the buffer layer initially absorbs and buffers the seismic energy, and the remaining energy is further consumed by the three sets of energy-dissipating layers, which greatly reduces the energy transmitted to the upper structure of the building, thereby improving its seismic isolation effect to a certain extent and enhancing the practicality of the device.

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.

[0021] Example 1

[0022] As attached Figures 1 to 4 The seismic isolation bearing and installation structure shown includes a lower connecting steel plate 1, an energy dissipation component 5 is provided at the upper end of the lower connecting steel plate 1, the energy dissipation component 5 includes a first energy dissipation layer 51, a second energy dissipation layer 52 is fixedly provided on one side of the first energy dissipation layer 51, and a third energy dissipation layer 53 is fixedly adhered to one side of the second energy dissipation layer 52.

[0023] Specifically, by using three sets of energy-dissipating layers in combination, the remaining energy after the buffer layer has initially absorbed and buffered the seismic energy is further consumed, which greatly reduces the energy transmitted to the upper structure of the building. At the same time, it has high strength and hardness, which enables it to maintain its shape and structural integrity when subjected to large horizontal loads and friction, thus enhancing the practicality of the device.

[0024] Example 2

[0025] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, the first energy-dissipating layer 51 is made of polytetrafluoroethylene, the second energy-dissipating layer 52 is made of graphite, and the third energy-dissipating layer 53 is made of copper alloy. Furthermore, by providing the first energy-dissipating layer 51, a smooth relative displacement can be generated between the superstructure and substructure of the bridge during an earthquake, reducing the transmission of seismic forces and making the device more widely applicable.

[0027] In a preferred embodiment, a middle steel plate 2 is provided at the upper end of the lower connecting steel plate 1, and an upper connecting steel plate 3 is provided at the upper end of the middle steel plate 2; furthermore, by providing three sets of steel plates, the number of connection points between the seismic isolation bearing and the building structure can be increased, thereby distributing the load borne by the seismic isolation bearing more evenly to the building structure.

[0028] In a preferred embodiment, a buffer assembly 4 is provided between the upper connecting steel plate 3 and the middle steel plate 2. The buffer assembly 4 includes a first buffer layer 41, a second buffer layer 42 is fixedly bonded to one side of the first buffer layer 41, and a third buffer layer 43 is fixedly provided to one side of the second buffer layer 42. Furthermore, by using the three sets of buffer layers in combination, the effect of buffering and shock absorption is achieved, which improves the practicality of the device to a certain extent.

[0029] In a preferred embodiment, the first buffer layer 41 is made of rubber material, the second buffer layer 42 is made of polyurethane foam material, and the third buffer layer 43 is made of metal spring material; furthermore, by making the first buffer layer 41 of rubber material, it can quickly return to its original shape after being compressed or stretched, repeatedly buffering energy, just like a highly elastic spring, reducing the impact of impact on the building.

[0030] In a preferred embodiment, steel strands 6 are connected to the lower connecting steel plate 1, the middle steel plate 2 and the upper connecting steel plate 3 through through holes, and mounting seats 7 are symmetrically arranged at both ends of the lower connecting steel plate 1; furthermore, by providing steel strands 6, it is ensured that when bearing the self-weight of the building and other vertical loads, the various components of the seismic isolation bearing are tightly connected and will not loosen or separate.

[0031] The working process of this utility model is as follows:

[0032] In use, the device is first constructed with a lower connecting steel plate 1, a middle steel plate 2, and an upper connecting steel plate 3. These three sets of connecting steel plates increase the number of connection points between the seismic isolation bearing and the building structure, thus distributing the load borne by the seismic isolation bearing more evenly across the building structure, enhancing the device's practicality. Secondly, three energy-dissipating layers, made of polytetrafluoroethylene (PTFE), graphite, and copper alloy respectively, are placed between the lower connecting steel plate 1 and the middle steel plate 2. These layers facilitate smooth relative displacement between the superstructure and substructure of the bridge during earthquakes, reducing the transmission of seismic forces. Simultaneously, graphite provides continuous lubrication during relative movement, reducing friction and effectively minimizing wear. Furthermore, the high strength and hardness of the copper alloy allow it to maintain its shape and structural integrity even under large horizontal loads and frictional forces. Finally, the upper connecting steel plate 3 and the middle steel plate 2... Three buffer layers, made of rubber, polyurethane foam, and metal, are arranged between the steel plates 2. These layers allow the steel plates to quickly return to their original shape after compression or stretching, repeatedly buffering energy like a highly elastic spring. This reduces the impact of the impact on the building. Furthermore, the metal spring does not add excessive weight to the seismic isolation bearing or the protected structure during use. Within certain elastic limits, the force and deformation of the metal spring exhibit a linear relationship. This characteristic allows the spring's performance during the buffering process to be accurately predicted and controlled, thereby expanding the applicability of the device. Finally, the steel strands 6 can be pre-tensioned, increasing the vertical load-bearing capacity of the seismic isolation bearing. This ensures that when bearing the building's self-weight and other vertical loads, the components of the seismic isolation bearing remain tightly connected, preventing loosening or separation. This enhances the device's practicality and broadens its application range.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
