Description

Technical Field

[0001] This invention relates to the field of seismic isolation technology, and in particular to a seismic isolation bearing tensile device and a seismic isolation system. Background Technology

[0002] As buildings evolve from low-rise, simple structures to high-rise, complex structures, seismic isolation devices are receiving increasing attention. Installing seismic isolation devices in building structures can reduce the vibration response of the upper structure, thus lowering the risk of earthquake damage.

[0003] When a building is subjected to an earthquake, seismic waves gradually propagate from the bottom to the top. During this process, the lower part of the building vibrates, while the upper part remains relatively stationary. In this situation, seismic isolation bearings installed on the supports deform to isolate the building, thereby reducing the amplitude of vibration in the upper part. Currently, common seismic isolation devices are mainly rubber seismic isolation bearings and friction pendulum seismic isolation bearings. However, both of these have insufficient tensile strength, making them prone to damage when subjected to significant tensile stress. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a seismic isolation bearing tensile device and a seismic isolation system for adaptively adjusting the tensile position of the tensile structure to better resist the vibration tensile effect.

[0005] The above-mentioned objective of this invention can be achieved by the following technical solution: This invention provides a seismic isolation bearing tensile device, comprising:

[0006] The upper and lower mounting structures are set relative to each other;

[0007] A tensile structure is disposed between the upper mounting structure and the lower mounting structure, one end of the tensile structure being rotatably connected to the upper mounting structure, and the other end of the tensile structure being slidably connected to the lower mounting structure;

[0008] A first limiting structure is disposed between the tensile structure and the upper mounting structure, and the first limiting structure can limit the tensile structure and the upper mounting structure along the axial direction of the seismic isolation bearing;

[0009] A second limiting structure is disposed between the tensile structure and the lower mounting structure. The second limiting structure can limit the tensile structure and the lower mounting structure along the axial direction of the seismic isolation bearing.

[0010] In a preferred embodiment of the present invention, the tensile structure includes a first tensile member and a second tensile member connected together. The first tensile member is rotatably connected to the upper mounting structure, and the second tensile member is slidably connected to the lower mounting structure.

[0011] In a preferred embodiment of the present invention, the upper mounting structure includes a first embedded part, the first embedded part having a mounting hole, one end of the first tensile member being rotatably disposed in the mounting hole, and the first limiting structure being disposed between the first embedded part and the first tensile member.

[0012] In a preferred embodiment of the present invention, the first limiting structure includes a first limiting groove disposed in the first embedded part and a first limiting block disposed at one end of the first tensile member. The bottom of the first limiting groove is connected to the mounting hole. The first limiting block is rotatably disposed in the first limiting groove. The first limiting block and the bottom of the first limiting groove can form an axial limiting.

[0013] In a preferred embodiment of the present invention, the lower mounting structure includes a second embedded part, the second embedded part being provided with a sliding groove, the sliding groove being circumferentially arranged along the axis of the mounting hole, one end of the second tensile member being slidably disposed in the sliding groove, and the second limiting structure being disposed between the second embedded part and the second tensile member.

[0014] In a preferred embodiment of the present invention, the second limiting structure includes a second limiting groove disposed in the second embedded part and a second limiting block disposed at one end of the second tensile member. The groove is connected to the bottom of the second limiting groove, and the second limiting block is slidably disposed in the second limiting groove. The second limiting block and the bottom of the second limiting groove can form an axial limiting.

[0015] In a preferred embodiment of the present invention, both the first tensile member and the second tensile member are arranged along the axial direction of the seismic isolation bearing, and a connecting member is provided between the other end of the first tensile member and the other end of the second tensile member.

[0016] In a preferred embodiment of the present invention, the first tensile member, the second tensile member, and the connecting member are integrally formed.

[0017] The present invention also provides a seismic isolation system, comprising:

[0018] Seismic isolation bearings are installed between the superstructure and the substructure;

[0019] Multiple aforementioned seismic isolation bearing tensile devices are provided, with each seismic isolation bearing tensile device arranged at intervals along the circumference of the seismic isolation bearing.

[0020] In a preferred embodiment of the present invention, the seismic isolation system further includes an upper support pier disposed on the upper structure and a lower support pier disposed on the lower structure, and the seismic isolation bearing is disposed between the upper support pier and the lower support pier.

[0021] In a preferred embodiment of the present invention, the upper structure is one of an upper beam, an upper plate, or an upper column, and the lower structure is one of a lower beam, a lower plate, or a lower column.

[0022] The technical solution of the present invention has the following significant beneficial effects:

[0023] In use, the seismic isolation bearing tensile device of this invention has an upper mounting structure connected to an upper structure and a lower mounting structure connected to a lower structure, thereby installing the tensile structure between the upper and lower structures. Furthermore, one end of the tensile structure can be rotatably connected to the upper mounting structure, and the other end can be slidably connected to the lower mounting structure, resulting in better installation stability and allowing the tensile structure to adaptively adjust its position under vibration, thus providing better tensile resistance between the upper and lower structures.

[0024] Furthermore, seismic isolation bearings are installed between the superstructure and the substructure, and these bearings have excellent horizontal seismic isolation capabilities. Under horizontal vibration, the seismic isolation bearings can deform to provide seismic isolation between the superstructure and the substructure, effectively preventing vibration damage to both structures.

[0025] Because the other end of the tensile structure is slidably connected to the lower mounting structure, the tensile structure can spontaneously adjust its connection position without affecting the horizontal deformation of the seismic isolation bearing. When vertical vibrations exert tensile stress on the seismic isolation bearing, the tensile structure will slide to the longitudinal separation position between the upper and lower structures, resisting the tensile stress exerted on the seismic isolation bearing by both structures and preventing tensile failure. By using the tensile structure in conjunction with the seismic isolation bearing, both effective seismic isolation and the risk of tensile failure of the seismic isolation bearing can be reduced.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Implementation Method 1

[0047] Please refer to the following: Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a seismic isolation bearing tensile device, which includes: an upper mounting structure 1 and a lower mounting structure 2 disposed opposite to each other; a tensile structure 3 disposed between the upper mounting structure 1 and the lower mounting structure 2, one end of the tensile structure 3 being rotatably connected to the upper mounting structure 1, and the other end of the tensile structure 3 being slidably connected to the lower mounting structure 2; a first limiting structure 4 disposed between the tensile structure 3 and the upper mounting structure 1, the first limiting structure 4 being able to limit the tensile structure 3 and the upper mounting structure 1 along the axial direction of the seismic isolation bearing 100; and a second limiting structure 5 disposed between the tensile structure 3 and the lower mounting structure 2, the second limiting structure 5 being able to limit the tensile structure 3 and the lower mounting structure 2 along the axial direction of the seismic isolation bearing 100.

[0048] Overall, in use, the upper mounting structure 1 is connected to the upper structure 200, and the lower mounting structure 2 is connected to the lower structure 300, thereby installing the tensile structure 3 between the upper structure 200 and the lower structure 300. Furthermore, one end of the tensile structure 3 can be rotatably connected to the upper mounting structure 1, and the other end can be slidably connected to the lower mounting structure 2, giving the tensile structure 3 better installation stability. Moreover, the tensile structure 3 can adaptively adjust its position under vibration, thus providing better tensile resistance between the upper structure 200 and the lower structure 300.

[0049] Specifically, multiple seismic isolation bearing tensile devices can be installed between the upper structure 200 and the lower structure 300. By arranging these multiple tensile devices along the circumference of the seismic isolation bearing 100 in different directions, each tensile device can work together to resist the tensile stress caused by vibration in each direction, preventing the seismic isolation bearing 100 from failing under tension and achieving better tensile resistance. Designers can adjust the number and location of each tensile device according to usage needs; no specific restrictions are imposed here.

[0050] In an embodiment of the present invention, the tensile structure 3 includes a first tensile member 31 and a second tensile member 32 connected to each other. The first tensile member 31 is rotatably connected to the upper mounting structure 1, and the second tensile member 32 is slidably connected to the lower mounting structure 2.

[0051] During horizontal vibration transmission, the lower structure 300 will vibrate before the upper structure 200. With a seismic isolation bearing 100 between the upper structure 200 and the lower structure 300, the bearing 100 provides seismic isolation, thereby reducing vibration on the upper structure 200. Therefore, the upper structure 200 can be considered to be in a stationary state compared to the lower structure 300.

[0052] When the upper mounting structure 1 is installed on the upper structure 200, the vibration on the upper mounting structure 1 is small, the relative displacement between the upper mounting structure 1 and the first tensile member 31 is small, and the first tensile member 31 does not need to adjust its position spontaneously.

[0053] When the lower mounting structure 2 is installed on the lower structure 300, the vibration on the lower mounting structure 2 is relatively large, and a large relative displacement will occur between the lower mounting structure 2 and the second tensile member 32. Therefore, the second tensile member 32 needs to spontaneously adjust its position to avoid interference from the horizontal vibration displacement on the lower mounting structure 2.

[0054] In this application, by rotatably connecting the first tensile member 31 to the upper mounting structure 1, the first tensile member 31 can be rotated and adjusted. This allows the first tensile member 31 to drive the second tensile member 32 to slide 360° on the lower mounting structure 2, providing a wider adjustment range. Because the second tensile member 32 is slidably connected to the lower mounting structure 2, when the lower mounting structure 2 experiences horizontal vibration displacement, the second tensile member 32 can spontaneously slide on the lower mounting structure 2, thereby adjusting the connection position between the second tensile member 32 and the lower mounting structure 2. This ensures that the tensile structure 3 remains vertically between the upper mounting structure 1 and the lower mounting structure 2, preventing interference from the vibration displacement of the lower mounting structure 2 on the second tensile member 32.

[0055] Furthermore, by spontaneously adjusting its position, the second tensile member 32 also prevents horizontal vibrations from being transmitted to the second tensile member 32 and the first tensile member 31, thereby improving the stability of the second tensile member 32 and the first tensile member 31 in use.

[0056] The present invention uses a first tensile member 31 and a second tensile member 32 to cooperate. The second tensile member 32 can slide and adjust 360° around the first tensile member 31, which has a larger horizontal adjustment range and better adjustment flexibility, so that the second tensile member 32 can be used under different vibration conditions.

[0057] In embodiments of the present invention, such as Figure 3 and Figure 5 In the embodiment shown, the upper mounting structure 1 includes a first embedded part 11, the first embedded part 11 is provided with a mounting hole 111, one end of the first tensile member 31 is rotatably disposed in the mounting hole 111, and the first limiting structure 4 is disposed between the first embedded part 11 and the first tensile member 31.

[0058] By pre-embedding the first embedded part 11 in the upper structure 200, the upper mounting structure 1 and the upper structure 200 can be more firmly connected, avoiding the problem of loosening. Furthermore, one end of the first tensile member 31 is rotatably disposed in the mounting hole 111, allowing for 360° stepless adjustment between the first tensile member 31 and the mounting hole 111, providing better adjustment flexibility.

[0059] In an embodiment of the present invention, the first limiting structure 4 includes a first limiting groove 41 disposed in the first embedded part 11 and a first limiting block 42 disposed at one end of the first tensile member 31. The bottom of the first limiting groove 41 is connected to the mounting hole 111. The first limiting block 42 is rotatably disposed in the first limiting groove 41. The first limiting block 42 and the bottom of the first limiting groove 41 can form an axial limiting.

[0060] Specifically, the first embedded part 11 includes an upper end plate 112 and an upper cover plate 113 covering the upper end plate 112. The upper end plate 112 and the upper cover plate 113 are clamped to form a first limiting groove 41, and a portion of the upper cover plate 113 extends outward in a cylindrical shape to form an installation hole 111.

[0061] Furthermore, the first limiting groove 41 is cylindrical, and the first limiting block 42 is circular plate-shaped, so that the first limiting block 42 can form an axial limit with the bottom of the first limiting groove 41, and the first limiting block 42 can rotate infinitely within the first limiting groove 41.

[0062] Furthermore, a certain axial gap is reserved between the bottom of the first limiting groove 41 and the upper end plate 112. This axial gap can provide a certain axial movement margin for the first limiting block 42, thus avoiding the problem of the first limiting block getting stuck.

[0063] In embodiments of the present invention, such as Figure 4 and Figure 6In the embodiment shown, the lower mounting structure 2 includes a second embedded part 21, on which a sliding groove 211 is provided. The sliding groove 211 is circumferentially arranged along the axis of the mounting hole 111. One end of the second tensile member 32 is slidably disposed in the sliding groove 211. The second limiting structure 5 is disposed between the second embedded part 21 and the second tensile member 32.

[0064] By pre-embedding the second embedded part 21 in the lower structure 300, the lower mounting structure 2 and the lower structure 300 can be more firmly connected, avoiding the problem of loosening. Furthermore, one end of the second tensile member 32 is slidably disposed in the slide groove 211, allowing one end of the second tensile member 32 to be infinitely adjustable 360° along the slide groove 211, providing a wider adjustment range.

[0065] Specifically, the slide 211 is arranged in a ring shape. The axis of the slide 211 is collinear with the axis of the mounting hole 111, so that when the second tensile member 32 rotates and adjusts along the slide 211, the first tensile member 31 can rotate synchronously in the mounting hole 111, resulting in better performance. Designers can determine the radius of the slide 211 based on the horizontal deformation of the seismic isolation bearing 100, and no specific restrictions are imposed here.

[0066] When the seismic isolation bearing 100 undergoes horizontal deformation, the first tensile member 31 will not be adjusted horizontally with the upper mounting structure 1, while the second tensile member 32 is slidably disposed in the lower mounting structure 2. The second tensile member 32 can be adjusted horizontally along the sliding groove 211, so that the tensile structure 3 can always be kept vertically between the upper structure 200 and the lower structure 300 to play a tensile role, without affecting the horizontal deformation of the seismic isolation bearing 100.

[0067] like Figure 7 As shown, when the lower mounting structure 2 is affected by horizontal vibration, the second tensile member 32 slides along the slide groove 211, so that the axis of the second tensile member 32 changes with the axis of the first tensile member 31 in the horizontal direction, thereby enabling the first tensile member 31 and the second tensile member 32 to remain vertical.

[0068] When the lower installation structure 2 is affected by vertical vibration, the first tensile member 31 and the second tensile member 32 can replace the seismic isolation support 100 to resist the vertical tensile stress and prevent the seismic isolation support 100 from being damaged by tension.

[0069] In an embodiment of the present invention, the second limiting structure 5 includes a second limiting groove 51 disposed in the second embedded part 21 and a second limiting block 52 disposed at one end of the second tensile member 32. The sliding groove 211 is connected to the bottom of the second limiting groove 51. The second limiting block 52 is slidably disposed in the second limiting groove 51. The second limiting block 52 and the bottom of the second limiting groove 51 can form an axial limiting.

[0070] Specifically, the second embedded part 21 includes a lower end plate 212 and a lower cover plate 213 covering the lower end plate 212. The lower cover plate 213 and the lower end plate 212 are clamped to form a second limiting groove 51, and a sliding groove 211 is provided on the lower cover plate 213.

[0071] Furthermore, the second limiting groove 51 is cylindrical, and the second limiting block 52 is cylindrical, so that the second limiting block 52 can form an axial limit with the bottom of the second limiting groove 51. A sliding groove 211 is provided at the bottom of the second limiting groove 51. Moreover, one end of the second tensile member 32 is inserted into the sliding groove 211 and can slide infinitely 360° along the sliding groove 211.

[0072] Furthermore, a certain axial gap is reserved between the bottom of the second limiting groove 51 and the lower end plate 212. This axial gap can provide a certain axial movement margin for the second limiting block 52, thus avoiding the problem of the second limiting block 52 getting stuck.

[0073] In one feasible embodiment, one end of the second tensile member 32 is directly inserted into the slide groove 211, and one end of the second tensile member 32 is fixedly connected to the second limiting block 52.

[0074] In other embodiments, one end of the second tensile member 32 may be provided with a connecting rod, which is inserted into the slide groove 211 and the second limiting block 52 is fixedly connected to the connecting rod.

[0075] Designers may adjust the installation structure of the second tensile member 32 and the second limiting block 52 according to the needs of use, and there are no restrictions here.

[0076] In an embodiment of the present invention, the first tensile member 31 and the second tensile member 32 are both arranged along the axial direction of the seismic isolation support 100, and a connecting member 6 is provided between the other end of the first tensile member 31 and the other end of the second tensile member 32.

[0077] By providing a connector 6 between the first tensile member 31 and the second tensile member 32, a horizontal installation allowance is provided, allowing the second tensile member 32 to rotate synchronously along the slide groove 211 when the first tensile member 31 rotates in the mounting hole 111. The size of the connector 6 can be adjusted by the designer according to the radius of the slide groove 211, and no specific limitation is made here.

[0078] Furthermore, the mounting hole 111 and the slide groove 211 have a common axis, which allows the first tensile member 31 and the second tensile member 32 to rotate synchronously, avoiding the problem of jamming during rotation.

[0079] In an embodiment of the present invention, the first tensile member 31, the second tensile member 32, and the connector 6 are integrally formed. By integrating the first tensile member 31, the second tensile member 32, and the connector 6, the structural strength of the tensile structure 3 is improved, the risk of the tensile structure 3 being damaged under tension is reduced, and the service life of the tensile structure 3 is increased.

[0080] In one specific embodiment, both the first tensile member 31 and the second tensile member 32 are rods, and the connecting member 6 is a connecting block disposed between the first tensile member 31 and the second tensile member 32. The axis of the first tensile member 31 and the axis of the second tensile member 32 are arranged parallel to each other.

[0081] In other embodiments, the designer may adjust the specific structure of the first tensile member 31 and the second tensile member 32 according to the needs of use, and no specific restrictions are imposed here.

[0082] Implementation Method 2

[0083] Please refer to the following: Figure 1 As shown, an embodiment of the present invention also provides a seismic isolation system, which includes: a seismic isolation bearing 100 disposed between the upper structure 200 and the lower structure 300; and a plurality of seismic isolation bearing tensile devices as described in Embodiment 1, wherein each seismic isolation bearing tensile device is disposed at intervals along the circumference of the seismic isolation bearing 100.

[0084] The specific structure, working principle, and beneficial effects of the seismic isolation bearing tensile device are the same as those described in Embodiment 1, and will not be repeated here. This seismic isolation system is equipped with multiple seismic isolation bearing tensile devices, which can exert tensile force in multiple directions, preventing the seismic isolation bearing 100 from being damaged by tension and improving the service life of the seismic isolation bearing 100.

[0085] Designers can adjust the number of tensile devices on the seismic isolation bearing according to usage requirements, and no specific limit is imposed here. For example, in one feasible embodiment, two tensile devices are provided on the seismic isolation bearing, and the two tensile devices are arranged opposite to each other on both sides of the seismic isolation bearing.

[0086] In another feasible embodiment, four tensile devices are provided for the seismic isolation bearing, and the four tensile devices are arranged at equal intervals around the seismic isolation bearing.

[0087] In an embodiment of the present invention, the seismic isolation system further includes an upper support 7 disposed on the upper structure 200 and a lower support 8 disposed on the lower structure 300, and the seismic isolation bearing 100 is disposed between the upper support 7 and the lower support 8.

[0088] By installing upper supports 7 on the superstructure 200, the installation distance between the seismic isolation bearing 100 and the superstructure 200 is reduced. Similarly, by installing lower supports 8 on the substructure 300, the installation distance between the seismic isolation bearing 100 and the substructure 300 is reduced. The coordinated operation of the upper supports 7 and lower supports 8 facilitates control over the spacing between them, enabling better installation of seismic isolation bearings 100 of different sizes and types.

[0089] Designers can adjust the structure of the seismic isolation bearing 100 according to the needs of use. For example, the seismic isolation bearing 100 can be a rubber bearing, which is not limited here.

[0090] Furthermore, designers can also install multiple seismic isolation bearings 100 between the upper structure 200 and the lower structure 300. The multiple seismic isolation bearings 100 can work together to enhance the effect and thus achieve better seismic isolation.

[0091] In one specific embodiment, the upper support 7 is integrally formed with the superstructure 200, thereby improving the connection strength between the upper support 7 and the superstructure 200. The lower support 8 is integrally formed with the lower structure 300, thereby improving the connection strength between the lower support 8 and the lower structure 300.

[0092] In one feasible embodiment of the present invention, the upper structure 200 is an upper beam, and the lower structure 300 is a lower beam. Seismic isolation bearings are disposed between the upper and lower beams, and multiple seismic isolation bearing tensile devices are arranged around the seismic isolation bearing 100 between the upper and lower beams.

[0093] In another feasible embodiment, the upper structure 200 is an upper plate, and the lower structure 300 is a lower plate. Seismic isolation bearings are disposed between the upper and lower plates, and multiple seismic isolation bearing tensile devices are arranged around the seismic isolation bearing 100 between the upper and lower plates.

[0094] In another specific embodiment, the upper structure 200 is an upper column, and the lower structure 300 is a lower column. Seismic isolation bearings are disposed between the upper and lower columns, and multiple seismic isolation bearing tensile devices are disposed around the seismic isolation bearing 100 between the upper and lower columns.

[0095] In other embodiments, the upper structure 200 is any one of an upper beam, an upper slab, or an upper column, and the lower structure 300 is any one of a lower beam, a lower slab, or a lower column; no limitation is made here.
