Description

Technical Field

[0001] This invention relates to the field of building vibration reduction technology, specifically a seismic isolation bearing. Background Technology

[0002] Seismic isolation bearings are support devices installed in building structures to achieve seismic isolation requirements. They involve adding a seismic isolation layer between the superstructure and the foundation, and installing rubber seismic isolation bearings to provide a flexible connection between the superstructure and the foundation. This technology can offset some of the energy from an earthquake. Examples include laminated rubber bearings, seismic isolation rubber bearings, and sandwiched rubber pads. These structures are structural components with low horizontal stiffness but high vertical stiffness, capable of withstanding large horizontal deformations, and therefore can be used as part of the load-bearing system.

[0003] However, traditional rubber seismic isolation bearings mostly use a layer of rubber and a layer of steel plate stacked together. The steel plate provides rigid support, and the rubber achieves the effect of damping by deforming and friction. Traditional rubber seismic isolation bearings rely on the deformation of the rubber for reset; however, the reset ability of rubber is relatively weak. If a large displacement occurs, traditional rubber seismic isolation bearings are prone to instability. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a seismic isolation bearing that has strong restoring properties and will not become unstable when there is a large shaking.

[0005] The technical solution adopted by this invention to solve its technical problem is: A seismic isolation bearing includes a bearing body, which includes an upper mounting plate and a lower mounting plate. The upper mounting plate is connected to the superstructure, and the lower mounting plate is connected to the foundation. A rubber cylinder is connected between the upper and lower mounting plates. An auxiliary component is provided inside the rubber cylinder. The auxiliary component includes an upper mounting block and a lower mounting block. A reset steel plate is connected between the upper and lower mounting blocks.

[0006] Compared with the prior art, the beneficial effects of the present invention are: By incorporating auxiliary components, this invention can help the rubber cylinder automatically reset when it deforms, and can effectively prevent instability caused by large displacement and shaking, thus making the device more stable during use.

[0007] As a preferred embodiment, a further technical solution of the present invention is: Preferably, the interior of the seismic isolation bearing is provided with several layers of support pads along the axial direction of the rubber sleeve.

[0008] Preferably, the auxiliary components are provided in two sets. The upper mounting plate has an upper mounting slot for each upper mounting block in each set of auxiliary components, and each upper mounting block is engaged with its corresponding upper mounting slot. The lower mounting plate has a lower mounting slot for each lower mounting block in each set of auxiliary components, and the lower mounting block is placed in the lower mounting slot.

[0009] Preferably, each lower mounting slot is provided with a guide post, and the lower mounting block is engaged with the guide post; the reset steel plate is placed between the two guide posts.

[0010] Preferably, a limiting auxiliary plate 1 is provided on the right side of the upper mounting block of the auxiliary component on the left side, and a limiting auxiliary plate 2 is provided on the left side of the lower mounting block of the auxiliary component on the right side. The limiting auxiliary plate 1 and the limiting auxiliary plate 2 are bent into an L-shape, and the bending directions of the limiting auxiliary plate 1 and the limiting auxiliary plate 2 are opposite.

[0011] Preferably, each upper mounting block is connected to the upper mounting plate via a fixing component; each fixing component includes a slot and a T-shaped insert, the T-shaped insert being movably installed in the slot, and one end of the T-shaped insert penetrating the slot and being inserted into the upper mounting plate.

[0012] Preferably, each slot is connected to the T-shaped insert placed in the slot by an elastic element.

[0013] Preferably, each slot is also provided with a locking block, and each locking block abuts against the T-shaped insert in its corresponding slot.

[0016] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0017] Example 1: A seismic isolation bearing includes a bearing body, which is composed of an upper mounting plate 3 and a lower mounting plate 4. The upper mounting plate 3 is connected to the superstructure, and the lower mounting plate 4 is connected to the foundation. A rubber cylinder 5 is fixedly connected between the upper and lower mounting plates 4. Several layers of annular support pads 6 are installed inside the rubber cylinder 5, and at least two sets of auxiliary components 1 are installed at the center of the rubber cylinder 5.

[0018] In this embodiment, the auxiliary component 1 is provided in two sets. Each set of auxiliary components 1 consists of an upper mounting block 101 and a lower mounting block 102. The upper mounting plate 3 is provided with an upper mounting groove 301 corresponding to the upper mounting block 101 in each set of auxiliary components 1. Each upper mounting block 101 is snapped into its corresponding upper mounting groove 301. The lower mounting plate 4 is provided with a lower mounting groove 401 corresponding to the lower mounting block 102 in each set of auxiliary components 1. The lower mounting block 102 is placed in the lower mounting groove 401. A reset steel plate 103 is provided between the upper mounting block 101 and the lower mounting block 102. The lower end of the reset steel plate 103 is fixedly connected to its corresponding lower mounting block 102, and the upper end of the reset steel plate 103 is fixedly connected to its corresponding upper mounting block 101.

[0019] In this embodiment, the reset steel plate 103 is made of a material with high yield strength.

[0020] In this embodiment, the width of the lower mounting block 102 is smaller than the width of the upper mounting block 101, which makes it easier to pull the lower mounting block 102 out from above the upper mounting plate 3, so that the auxiliary component 1 can be disassembled and maintained.

[0021] Each lower mounting slot 401 is also symmetrically provided with two guide posts 104, which pass through the lower mounting block 102 and are engaged with the lower mounting block 102; the reset steel plate 103 is placed between the two guide posts 104, and the distance between the two guide posts 104 in each group is greater than the width of the reset steel plate 103, so that when the upper mounting plate 3 and the lower mounting plate 4 are offset,

[0022] In this embodiment, among the two sets of auxiliary components 1, the right side of the upper mounting block 101 of the left auxiliary component 1 is fixedly connected to a limiting auxiliary plate 105, and the left side of the lower mounting block 102 of the right auxiliary component 1 is fixedly connected to a limiting auxiliary plate 106. The limiting auxiliary plate 105 and the limiting auxiliary plate 106 are bent into L-shapes, and the bending directions of the limiting auxiliary plate 105 and the limiting auxiliary plate 106 are opposite.

[0023] In this embodiment, the lower end of the limiting auxiliary plate 105 is lower than the top end of the guide post 104 and the top end of the limiting auxiliary plate 106, and the width of the limiting auxiliary plate 105 is greater than the distance between the two guide posts 104 in the same group. When the upper mounting plate 3 and the lower mounting plate 4 are offset, the left guide post 104 and the limiting auxiliary plate 105 can cooperate to prevent the upper mounting plate 3 from shifting to the left, and the limiting auxiliary plate 105 and the limiting auxiliary plate 106 can cooperate to prevent the upper mounting plate 3 from shifting to the right.

[0024] In this embodiment, the lower mounting plate 4 is fixedly connected to the foundation, the upper mounting plate 3 is connected to the upper building structure, and the auxiliary component 1 is installed inside the rubber sleeve 5. Then, the lower mounting block 102 is inserted into the lower mounting groove 401 through the guide post 104. When a disaster such as an earthquake occurs, if the building shakes and deforms, the reset steel plate 103 will deform synchronously. Because the reset steel plate 103 has a large yield force, it can assist the rubber sleeve in quickly resetting. If the shaking is large and causes large displacement at both ends of the building, the second limiting auxiliary plate 106 will limit the rightward movement of the upper mounting plate 3, while the guide post 104 will limit the leftward movement of the first limiting auxiliary plate 105. By setting the auxiliary component 1, the rubber sleeve 5 can be automatically reset when it deforms, and the large displacement and shaking of the entire device can be effectively avoided, thus preventing instability.

[0025] In Example 2, based on Example 1, the upper mounting plate 3 of this example is further provided with a fixing component 2 for each group of auxiliary components 1. The fixing component 2 consists of a slot 201 and a T-shaped rod 202. The T-shaped rod 202 is movably placed in the slot 201. One end of the slot 201 is provided with a clearance through hole. One end of the T-shaped rod 202 passes through and slides with the clearance through hole.

[0026] On the inner wall of the upper mounting groove 301 of the upper mounting plate 3, a slot 203 is provided corresponding to the position of the T-shaped plug 202 of the internal fixing component 2. The T-shaped plug is connected to the upper mounting plate 3 by inserting into the slot 203.

[0027] Each T-shaped rod is fixedly connected to the inner wall of the slot 201 by an elastic element 204, such as a spring.

[0028] Each slot 201 is also fitted with a locking block 205, which is placed inside the slot 201 and abuts against the T-shaped insert 202.

[0029] In this embodiment, the upper surface of the upper mounting plate 3 is provided with a retaining groove 206 for each group of fixing components 2. The retaining groove 206 is located at the end of the empty groove 201 away from the T-shaped insert 202, and the retaining groove 206 is connected to the through groove. The end of each locking block 205 away from the T-shaped insert 202 is fixedly connected with a retaining block 207 that engages with the retaining groove 206. The engagement of the retaining block 207 and the retaining groove 206 prevents the locking block 205 from sliding down from the inside of the empty groove 201.

[0030] The upper surfaces of the two upper mounting blocks 101 are respectively provided with lifting slots 7 to facilitate the overall lifting of the upper mounting blocks 101.

[0031] In this embodiment, before the upper mounting block 101 is inserted into the slot 203 of the upper mounting plate 3, the T-shaped rod 202 is positioned away from the upper mounting block 101 under the elastic force of the elastic member 204. When the upper mounting block 101 is inserted into the upper mounting groove 301, the position of the slot 203 is flush with the T-shaped rod 202. Then, the T-shaped rod 202 is pushed into the slot 203, and then the locking block 205 is installed in the empty slot 201, and the stop block 207 and the stop groove 206 are engaged. During installation, the upper mounting plate 3 is fixedly connected to the upper building, and the ground of the upper building will press the upper surfaces of the locking block 205 and the stop block 207, thus making the T-shaped rod 202 more stable inside the slot 203.

[0032] In this embodiment, by setting a fixing component, the auxiliary component can be more stable after the overall installation is completed, avoiding the situation where the upper mounting block detaches from the inside of the upper mounting plate when the building shakes, and further improving the stability of the support body during use.
