Description

Technical Field

[0001] This utility model belongs to the field of seismic isolation bearing technology, and particularly relates to a seismic isolation bearing for building construction. Background Technology

[0002] When a building is located in a seismic zone, various seismic isolation measures are taken to reduce the destructive effects of an earthquake on the building in order to protect the safety of users. Seismic isolation bearings are one such measure.

[0003] Compared with traditional seismic isolation engineering that uses reinforced reinforcement, seismic isolation bearings can better resist the effects of earthquakes, transferring the damaged parts from the steel bars in the vertical structure to the seismic isolation bearings, thus better ensuring the safety of the superstructure.

[0004] Currently, existing seismic isolation bearings have a simple structure, consisting of alternating layers of rubber and steel plates. The vertical tensile strength is determined by the bonding ability between the rubber and steel plates, but the bonding ability between the rubber and steel plates is not strong, resulting in weak tensile performance and poor practicality of the bearings. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a seismic isolation bearing for building construction, aiming to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] This utility model provides a seismic isolation bearing for building construction, including a bearing body;

[0008] The support body includes a column; wherein the top of the column is fixedly connected to the upper flange plate, and a plurality of second annular steel plates are slidably sleeved on the outer ring of the column.

[0009] The support body also includes a support sleeve, which is fixedly installed on the lower flange plate. The lower part of the support column slides into the support sleeve, meaning that the support column can have relative displacement with respect to the support sleeve in the vertical direction. Multiple first annular steel plates are slidably fitted onto the outer ring of the support sleeve.

[0010] The main body of the support also includes a vibration isolation sleeve. The inner ring of the vibration isolation sleeve has multiple receiving cavities. The receiving cavities cooperate with the corresponding first annular steel plates and second annular steel plates. In actual use, each first annular steel plate and each second annular steel plate is located in the corresponding receiving cavity. That is to say, multiple first annular steel plates and multiple second annular steel plates are arranged alternately. The space between two adjacent first annular steel plates or between two adjacent second annular steel plates is part of the vibration isolation sleeve. When the support column undergoes vertical displacement relative to the support sleeve, the vibration isolation sleeve between the multiple first annular steel plates and multiple second annular steel plates is compressed. The vibration isolation sleeve can play a good buffering and supporting role, that is, the vibration isolation role.

[0011] The lower flange plate has a first through hole and two second through holes, which are symmetrically located around the first through hole. The support body provided in this embodiment also includes a buffer support member, which is installed in the support sleeve through the first and second through holes. The bottom end of the support column has a top groove, and the top end of the top column included in the buffer support member rests in the top groove.

[0012] Furthermore, the upper flange plate is fixed to the upper support pier by a plurality of fixing bolts arranged in a circular pattern. The upper support pier is a concrete casting structure, and anchor bars and embedded sleeves are pre-embedded in the upper support pier. The bottom end of the anchor bar extends into and is fixed in the embedded sleeve. The inner cavity of the embedded sleeve has an internal thread structure. The upper flange plate is fixed to the upper support pier by fixing bolts that cooperate with the internal thread structure in the embedded sleeve.

[0013] Furthermore, the buffer support also includes a support cylinder, into which the top column slides through;

[0014] The bottom end of the support cylinder is a supporting base; the outer diameter of the support cylinder matches the inner diameter of the first through hole, and the support cylinder can pass through the first through hole.

[0015] Furthermore, the outer ring of the support cylinder is fixedly provided with two side plates, and the two support bases are symmetrically arranged and cooperate with the two second through holes. When the support cylinder is passed through the first through hole, the two side plates pass through the two second through holes respectively, so that the buffer support can smoothly pass through the first through hole and the second through hole and enter the support sleeve.

[0016] Furthermore, the bottom surface of the support sleeve is provided with two fixing grooves, which are symmetrically arranged on the bottom surface of the support sleeve and symmetrically arranged around the first through hole. The two side plates abut against the two fixing grooves respectively, and the two side plates are fixed in the corresponding two fixing grooves by using mounting bolts.

[0017] Furthermore, the bottom end of the top column slides into the support cylinder, and a support slider is fixedly provided at the bottom end of the top column. The support slider located inside the support cylinder is connected to the support base by a support spring. In this embodiment, the support spring is fixedly installed at the bottom opening of the support cylinder.

[0018] Furthermore, the outer circumferential surface of the supporting chassis has a groove structure.

[0019] Compared with the prior art, the beneficial effects of the seismic isolation bearing for building construction provided by this utility model are:

[0020] First, this utility model uses multiple first annular steel plates and multiple second annular steel plates embedded in multiple accommodating cavities within the seismic isolation sleeve, which can play a good seismic isolation support role. Moreover, the multiple first annular steel plates are sleeved on the support sleeve and the multiple second annular steel plates are sleeved on the column, which can improve the stability of the seismic isolation support.

[0021] Secondly, the buffer support component provided in this utility model can provide buffer support for the column, further improving the overall seismic isolation performance of the seismic isolation bearing. When the buffer support component extends into the support sleeve, rotating the buffer support component half a turn can cause the two side plates to abut against the two fixing grooves respectively. The two side plates are then fixed in the corresponding two fixing grooves using mounting bolts. At this time, the buffer support component is installed in the support sleeve and can support the bottom end of the column, allowing the column to slide through and extend into the support sleeve. When relative displacement occurs, the buffer support component can play a good buffer support role. Moreover, the buffer support component is easy to install and remove, and convenient for replacement and maintenance. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0035] like Figures 1-4 As shown, in one embodiment of this utility model, a seismic isolation bearing for building construction is provided. The seismic isolation bearing includes a bearing body, and the bearing body includes a support column 6.

[0036] The top of the support column 6 is fixedly connected to the upper flange plate 3, and a plurality of second annular steel plates 8 are slidably sleeved on the outer ring of the support column 6.

[0037] The support body also includes a support sleeve 53, which is fixedly installed on the lower flange plate 5. The lower part of the support column 6 slides into the support sleeve 53, that is, the support column 6 can generate relative displacement in the vertical direction relative to the support sleeve 53. Multiple first annular steel plates 7 are slidably sleeved on the outer ring of the support sleeve 53.

[0038] Furthermore, the support body provided in this embodiment also includes a vibration isolation sleeve 1. The inner ring of the vibration isolation sleeve 1 has multiple receiving cavities 11. The receiving cavities 11 cooperate with the corresponding first annular steel plate 7 and second annular steel plate 8. In specific use, each first annular steel plate 7 and each second annular steel plate 8 are located in the corresponding receiving cavity 11. That is, multiple first annular steel plates 7 and multiple second annular steel plates 8 are arranged sequentially at intervals. The space between two adjacent first annular steel plates 7 or between two adjacent second annular steel plates 8 is part of the vibration isolation sleeve 1. When the support column 6 undergoes vertical displacement relative to the support sleeve 53, the vibration isolation sleeve 1 between the multiple first annular steel plates 7 and multiple second annular steel plates 8 is compressed, and the vibration isolation sleeve 1 can play a good buffering and supporting role, that is, a vibration isolation role.

[0039] Please continue to refer to Figure 1 In this embodiment of the utility model, the upper flange plate 3 is fixed to the upper support 2 by a plurality of fixing bolts 23 arranged in a circular pattern. The upper support 2 is a concrete casting structure. Anchor bars 21 and pre-embedded sleeves 22 are pre-embedded in the upper support 2. The bottom end of the anchor bar 21 extends into and is fixed in the pre-embedded sleeve 22. The inner cavity of the pre-embedded sleeve 22 has an internal thread structure. The upper flange plate 3 is fixed to the upper support 2 by fixing bolts 23 that cooperate with the internal thread structure in the pre-embedded sleeve 22.

[0040] Similarly, the lower flange plate 5 provided in this embodiment is fixedly installed on the lower support 4. The lower support 4 is also a concrete casting structure. The connection method between the lower support 4 and the lower flange plate 5 is the same as the connection method between the upper flange plate 3 and the upper support 2, which will not be described in detail here.

[0041] Please continue to refer to Figures 4-8 In this embodiment of the utility model, a first through hole 51 is provided on the lower flange plate 5, and two second through holes 52 are also provided on the lower flange plate 5. The second through holes 52 are symmetrically located around the first through hole 51. The support body provided in this embodiment of the present invention also includes a buffer support member, which is installed in the support sleeve 53 through the first through hole 51 and the second through hole 52.

[0042] Specifically, the bottom end of the support column 6 is provided with a top groove 67, the buffer support includes a support cylinder 61 and a top column 62, the top end of the top column 62 rests in the top groove 67, and the top column 62 slides through into the support cylinder 61, the bottom end of the support cylinder 61 is a support base 64; the outer diameter of the support cylinder 61 matches the inner diameter of the first through hole 51, that is, the support cylinder 61 can pass through the first through hole 51;

[0043] Accordingly, in this embodiment of the utility model, the outer ring of the support cylinder 61 is fixedly provided with two side plates 63 and two supporting base plates 64 are symmetrically arranged and cooperate with two second through holes 52. When the support cylinder 61 passes through the first through hole 51, the two side plates 63 pass through the two second through holes 52 respectively, so that the buffer support can smoothly pass through the first through hole 51, the second through hole 52 and enter the support sleeve 53.

[0044] Furthermore, such as Figure 7 and Figure 8 As shown, the bottom surface of the support sleeve 53 (also called the upper surface of the lower flange plate 5) is provided with two fixing grooves 54. The two fixing grooves 54 are symmetrically arranged on the bottom surface of the support sleeve 53 and symmetrically arranged around the first through hole 51. That is to say, when the buffer support is inserted into the support sleeve 53, rotating the buffer support half a turn can make the two side plates 63 abut against the two fixing grooves 54 respectively. The two side plates 63 are further fixed in the corresponding two fixing grooves 54 by using mounting bolts. At this time, the buffer support is installed in the support sleeve 53 and can support the bottom end of the column 6, so that the column 6 slides through and extends into the support sleeve 53. When relative displacement occurs, the buffer support can play a good buffering and supporting role. Moreover, the buffer support provided by this utility model is easy to install and remove, and easy to replace and maintain.

[0045] Please continue to refer to Figure 4 In this embodiment of the utility model, the bottom end of the top column 62 slides into the support cylinder 61, and a support slider 66 is fixedly provided at the bottom end of the top column 62. The support slider 66 located in the support cylinder 61 is connected to the support base 64 by a support spring 65. The support spring 65 provided in this embodiment is fixedly installed at the bottom opening of the support cylinder 61.

[0046] Optionally, the outer circumferential surface of the support chassis 64 has a groove structure, which facilitates manual rotation of the support chassis 64, that is, allows the buffer support to rotate, making it easier to adjust the position of the buffer support within the support sleeve 53, and facilitating the disassembly and maintenance of the buffer support.

[0047] As can be seen, the seismic isolation bearing for building construction provided by this utility model, on the one hand, uses multiple first annular steel plates 7 and multiple second annular steel plates 8 embedded in multiple receiving cavities 11 within the seismic isolation sleeve 1, which can play a good seismic isolation support role. Moreover, the multiple first annular steel plates 7 are sleeved on the support sleeve 53 and the multiple second annular steel plates 8 are sleeved on the column 6, which can improve the stability of the seismic isolation bearing. On the other hand, the buffer support can provide buffer support for the column 6, further improving the overall seismic isolation performance of the seismic isolation bearing.

[0048] The above solutions are merely illustrative examples of preferred embodiments, but are not limited thereto. When implementing this invention, appropriate substitutions and / or modifications can be made according to the user's needs.
