Description

Technical Field

[0001] This invention belongs to the field of earthquake-resistant building structures, and more specifically relates to a vibration isolation bearing. Background Technology

[0002] Buildings are required to have certain seismic resistance during construction to ensure that they will not be damaged or even collapse when subjected to a certain degree of lateral or longitudinal vibration. Installing vibration isolation bearings on the building structure is an existing seismic resistance measure, which can achieve vibration isolation and buffering of the building by relying on its own elastic deformation.

[0003] The core component of existing vibration isolation bearings is a rubber pad. When a building is subjected to vibration, the rubber pad can alleviate the vertical and lateral vibrations of the building. However, the above-mentioned vibration isolation bearings still have shortcomings. For example, this type of vibration isolation bearing has a good elastic buffering effect when the building moves vertically downward, but it cannot effectively buffer the upward movement of the building. Furthermore, the horizontal seismic resistance and buffering performance of existing rubber pads are generally poor, and they cannot cope with high-frequency and large-amplitude lateral vibrations. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a vibration isolation bearing that has good buffering performance for both upward movement and lateral vibration of buildings.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] Vibration isolation bearings are installed between the building's columns and foundations. These bearings include horizontal and vertical vibration isolation components. The horizontal vibration isolation component comprises a buffer plate, a slider, a circular plate, a support column, and a cover plate. The buffer plate is horizontally arranged, and its upper surface has an annular oil channel, a sliding groove, an oil passage groove, and a buffer groove. The buffer groove is located inside the annular oil channel and centered relative to the inner circle of the annular oil channel. Multiple sliding grooves are arranged radially and evenly around the center of the inner circle of the annular oil channel, with one end of each sliding groove connected to the buffer groove. Multiple oil passage grooves are provided, with one end of each oil passage groove corresponding to the end of a sliding groove furthest from the buffer groove, and the other end of each oil passage groove connected to the annular oil channel. The cross-sectional area of ​​the oil passage groove is smaller than that of the sliding groove. Cross-sectional area; multiple sliders are provided, one end of which is slidably and tightly fitted into the groove, and the other end of which is located in the buffer groove; a circular plate is located in the buffer groove, the upper surface of the circular plate is vertically and fixedly connected to a support column, the lower surface of the circular plate is slidably and tightly attached to the bottom surface of the buffer groove, the upper surface of the circular plate is slidably and tightly attached to the lower surface of the cover plate, and the side wall of the circular plate can abut against one end wall of the slider; the upper surface of the buffer plate is tightly attached to and fixedly connected to the lower surface of the cover plate, and the upper side wall of the slider is slidably and tightly attached to the lower surface of the cover plate, so that the annular oil passage, the groove, and the oil passage groove form a relatively closed hydraulic cavity, and the annular oil passage, the groove, and the oil passage groove are all filled with hydraulic oil; the cover plate is centered An movable hole is provided, centrally located inside the buffer groove. A support column is situated within the movable hole, with its outer diameter smaller than the hole's diameter. The upper end of the support column is used for fixed connection to the building's columns. The vertical vibration isolation component includes a mounting plate, a hinge plate, a second hinge plate, an abutment plate, and a rubber column. The mounting plate is fixedly connected to the lower surface of the buffer plate, and its surface is perpendicular to the axis of the support column. Multiple hinge plates are provided, and one end of the hinge plate is hinged to the side wall of the mounting plate and has a hinge axis. The other end of the hinge plate is simultaneously hinged to one end of the second hinge plate and one end of the abutment plate, and has a hinge axis. Connecting axis two, the other end of hinge plate two is hinged to the side wall of mounting plate two and has hinge axis three. Hinges one, two and three on the same side of mounting plate one are parallel to each other. Hinges two is parallel to the surface of mounting plate one. Mounting plate two is used for fixed connection with the foundation of the building. Rubber column is located between mounting plate one and mounting plate two. The upper end of rubber column abuts against the lower surface of mounting plate one, and the lower end of rubber column abuts against the upper surface of mounting plate two. The outer side wall of rubber column is coaxially provided with an annular groove. Multiple abutment plates are evenly arranged along the circumference of rubber column. The end of the abutment plate away from hinge plate one is tightly embedded in the annular groove.

[0007] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a vibration isolation support. The present invention designs horizontal and vertical vibration isolation components. When the building is subjected to horizontal vibration, the circular plate moves horizontally, some of the sliders are compressed, and the hydraulic oil in the buffer plate flows. Since the cross-sectional area of ​​the sliding groove and the oil groove has a large difference, the hydraulic oil flow is obstructed. Therefore, the circular plate will be subjected to a certain hydraulic buffering effect when it moves. Regardless of the direction of horizontal displacement of the building, the horizontal vibration isolation component can play a buffering role. When the building is subjected to vertical vibration and the mounting plate moves down, the rubber column is axially compressed. The rubber column can elastically buffer and isolate the downward-moving mounting plate. When the mounting plate moves up, multiple abutment plates move closer to the rubber column at the same time. The abutment plates can press against the side wall of the rubber column, and the rubber column is subjected to circumferential force. The rubber column can elastically buffer and isolate the upward-moving mounting plate.

[0008] Preferably, the vibration isolation bearing further includes connecting members, which include an upper connecting plate and a lower connecting plate, both of which can be arranged horizontally. In specific implementation, the upper surface of the upper connecting plate is fixedly connected to the building's column, and the lower surface of the lower connecting plate is fixedly connected to the building's foundation. The end of the support column away from the circular plate is vertically fixedly connected to the lower surface of the upper connecting plate, and the lower surface of the mounting plate is tightly fixedly connected to the upper surface of the lower connecting plate. The horizontal vibration isolation member can be reliably fixed to the building's column using the upper connecting plate, and the vertical vibration isolation member can be reliably fixed to the building's foundation using the lower connecting plate.

[0009] Preferably, the horizontal vibration isolator also includes a shim with an opening in the central area. The shim is coaxially sleeved on the support column. The upper surface of the shim slides and fits tightly against the lower surface of the upper connecting plate, and the lower surface of the shim slides and fits tightly against the upper surface of the cover plate. In this way, excessive wear will not occur between the upper connecting plate and the cover plate.

[0010] Preferably, the outer wall of the buffer disc is provided with a filler nozzle that communicates with the annular oil passage, and hydraulic oil can be added to or released into the buffer disc using the filler nozzle.

[0011] Preferably, the end wall of the abutment plate away from the hinge plate is arc-shaped to fit the bottom wall of the annular groove, so that the abutment plate can contact the bottom wall of the annular groove more reliably.

[0012] Preferably, the buffer groove is a circular groove with an inner diameter larger than the outer diameter of the circular plate, and the end wall of the slider away from the annular oil passage is an arc shape that matches the side wall of the circular plate, so that the circular plate and the slider can abut more reliably.

[0013] Preferably, the vertical vibration isolation component further includes a second support column. The second support column is vertically fixed to the upper surface of the mounting plate. The second support column is coaxially arranged with the annular oil passage. A through hole is centrally located at the end of the rubber column, and the second support column is coaxially arranged within the through hole. The upper end face of the second support column can abut against the lower surface of the mounting plate. When the rubber column fails, the second support column can abut against the mounting plate, effectively ensuring that the vibration isolation support still has supporting performance.

Detailed Implementation

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0022] This invention discloses a vibration isolation support. By designing horizontal and vertical vibration isolation components, the horizontal vibration isolation component can buffer the connected columns and the structure above them when the building is subjected to horizontal vibrations. In this application, the horizontal vibration isolation component utilizes the difference in cross-sectional area between the circular plate 03 pushing the slider 02 and the sliding groove 011 and the oil passage 012. When the circular plate 03 moves horizontally, part of the slider 02 is compressed, and the hydraulic oil in the buffer plate 01 flows. Due to the large difference in cross-sectional area between the sliding groove 011 and the oil passage 012, the hydraulic oil flow is obstructed. Therefore, the circular plate 03 experiences a certain hydraulic buffering effect when moving. Simultaneously, because the sliding groove 011 is arranged radially, this horizontal vibration isolation component can provide buffering regardless of the direction of horizontal displacement of the building.

[0023] When a building is subjected to vertical vibrations, vertical vibration isolators can buffer the connected columns and the structure above the columns. In this application, the vertical vibration isolators utilize rubber columns 11, hinge plates 08 and 09, and abutment plates 10. When mounting plate 07 moves downward, the rubber columns 11 are axially compressed, and the rubber columns 11 can elastically buffer and isolate the downward-moving mounting plate 07. When mounting plate 07 moves upward, the angle between hinge plates 08 and 09 increases. Multiple abutment plates 10 simultaneously approach the rubber column 11, and the abutment plates 10 can press against the side wall of the rubber column 11. Therefore, when the mounting plate 07 moves upward, the rubber column 11 is subjected to circumferential force (the extrusion force applied by the abutment plates 10 is distributed in a ring). The rubber column 11 can provide elastic buffering and vibration isolation for the upward-moving mounting plate 07. By designing the annular groove 110, the abutment plates 10 can be reliably limited within the annular groove 110, and the multiple abutment plates 10 can stably and reliably press against the rubber column 11.

[0024] See appendix Figure 1-4 This is a schematic diagram of the overall and partial structure of one embodiment of the present invention. The present invention specifically discloses a vibration isolation support, which is installed between the columns and foundation of a building and mainly buffers and isolates the vertical and lateral displacement of the building. The vibration isolation support includes horizontal vibration isolation components and vertical vibration isolation components.

[0025] The horizontal vibration isolation component includes a buffer disc 01, a slider 02, a circular plate 03, a support column 04, and a cover plate 05. The buffer disc 01 is horizontally arranged, and its upper surface has an annular oil channel 010, a sliding groove 011, an oil passage groove 012, and a buffer groove 013. The buffer groove 013 is located inside the annular oil channel 010 and is centered relative to the inner circle of the annular oil channel 010. Multiple sliding grooves 011 are provided and are evenly arranged radially with the center of the inner circle of the annular oil channel 010 as the center. One end of each of the multiple sliding grooves 011 is connected to... The buffer groove 013 is connected, and multiple oil passage grooves 012 are provided. One end of each oil passage groove 012 is connected to the end of the slide groove 011 away from the buffer groove 013, and the other end of each oil passage groove 012 is connected to the annular oil passage 010. The cross-sectional area of ​​the oil passage groove 012 is smaller than that of the slide groove 011. Multiple sliders 02 are provided. One end of each slider 02 is slidably and tightly embedded in the slide groove 011, and the other end of each slider 02 is located in the buffer groove 013. The circular plate 03 is located in the buffer groove 013. The upper surface of the circular plate 03 is vertically and fixedly connected to the support column 04. The lower surface of the circular plate 03 slides and is in close contact with the bottom surface of the buffer groove 013. The upper surface of the circular plate 03 slides and is in close contact with the lower surface of the cover plate 05. The side wall of the circular plate 03 can abut against one end wall of the slider 02. The upper surface of the buffer plate 01 is in close contact with and fixedly connected to the lower surface of the cover plate 05. The upper side wall of the slider 02 slides and is in close contact with the lower surface of the cover plate 05, so that the annular oil passage 010, the slide groove 011, and the oil passage groove 012 form a relatively sealed structure. The closed hydraulic chamber (i.e., excluding necessary filler nozzle interfaces, slider movable end protrusions, etc., this hydraulic chamber is a closed cavity) is filled with hydraulic oil in the annular oil passage 010, slide groove 011, and oil passage groove 012. A movable hole 050 is centrally located on the cover plate 05, positioned inside the buffer groove 013. Support column 04 is located within the movable hole 050, and its outer diameter is smaller than the diameter of the movable hole 050. The upper end of support column 04 is used for fixed connection with the building's columns. It is understood that the sliding contact structure designed corresponding to the outer circumference of slider 02 is to prevent hydraulic oil from entering the buffer groove 013, which is generally achieved by setting a sealing ring.

[0026] Under normal circumstances, i.e., when the building is not subjected to vibration, the circular plate 03 is centrally located within the buffer groove 013, and one end of each of the multiple sliders 02 is in contact with the side wall of the circular plate 03. When the building is subjected to horizontal vibration, the support column 04, which is fixedly connected to the building's columns, will shift horizontally relative to the building's foundation. At this time, the circular plate 03 will slide within the buffer groove 013. When the circular plate 03 moves, some of the sliders 02 will be compressed. The compressed sliders 02 will push the hydraulic oil in their respective grooves 011, causing the hydraulic oil in the grooves 011 to... After passing through the oil groove 012, the oil enters the annular oil passage 010. Since the cross-sectional area of ​​the oil groove 012 is much smaller than that of the slide groove 011, the hydraulic oil cannot quickly flow from the slide groove 011 to the annular oil passage 010. Therefore, the pressurized slider 02 experiences some damping during movement. Simultaneously, due to the pressure on some sliders 02, the hydraulic oil in the slide groove 011 corresponding to the pressurized slider 02 enters the annular oil passage 010. Since the amount of hydraulic oil in the buffer plate 01 is constant, the hydraulic oil in the other part corresponding to the pressurized slider 02... The slider 02 slides inward into the buffer groove 013, meaning the hydraulic oil in the annular oil channel 010 passes through the oil channel 012 and enters the slide groove 011. This design ensures the balance of the hydraulic oil in the buffer plate 01. Regardless of the position of the support column 04, one end of each slider 02 is in contact with the side wall of the circular plate 03. Hydraulic oil flows from the slide groove 011 into the annular oil channel 010 and from the annular oil channel 010 into the slide groove 011. During the flow, the hydraulic oil provides a certain buffering effect on the movement of the circular plate 03, thus achieving lateral movement of the column. The buffer plate 01 has a buffering effect; a circular cover plate 05 is fixedly attached to the upper surface of the buffer plate 01. The upper side wall of the slider 02 and the upper plate surface of the circular plate 03 are slidably attached to the lower plate surface of the cover plate 05. A circular movable hole 050 is centrally located on the cover plate 05. The movable hole 050 is centrally located inside the buffer groove 013. A support column 04 is arranged in the movable hole 050. The outer diameter of the support column 04 is smaller than the diameter of the movable hole 050, ensuring that the support column 04 has a certain horizontal displacement distance relative to the buffer plate 01. The upper end of the support column 04 is fixed to the building column.

[0027] The vertical vibration isolation component includes mounting plate 107, hinge plate 108, hinge plate 209, abutment plate 10, mounting plate 216, and rubber column 11. Mounting plate 107 is fixedly connected to the lower surface of buffer plate 01, and the plate surface of mounting plate 107 is perpendicular to the axis of column 104. Multiple hinge plates 108, hinge plate 209, and abutment plate 10 are provided. One end of hinge plate 108 is hinged to the side wall of mounting plate 107 and has a hinge axis 1. The other end of hinge plate 108 is hinged to both one end of hinge plate 209 and one end of abutment plate 10 and has a hinge axis 2. The other end of hinge plate 209 is hinged to the side wall of mounting plate 216 and has a hinge axis. The hinge axis centerline 1, hinge axis centerline 2, and hinge axis centerline 3, located on the same side of mounting plate 107, are parallel to each other. The hinge axis centerline 2 is parallel to the surface of mounting plate 107. Mounting plate 2 16 is used for fixed connection with the foundation of the building. Rubber column 11 is located between mounting plate 107 and mounting plate 2 16. The upper end face of rubber column 11 abuts against the lower plate surface of mounting plate 107, and the lower end face of rubber column 11 abuts against the upper plate surface of mounting plate 2 16. The outer side wall of rubber column 11 is coaxially provided with an annular groove 110. Multiple abutment plates 10 are evenly arranged along the circumference of rubber column 11. The end of abutment plate 10 away from hinge plate 10 is tightly embedded in the annular groove 110.

[0028] Under normal circumstances, the two ends of the rubber column 11 abut against the mounting plate 107 and the mounting plate 216 respectively. The rubber column 11 undergoes elastic deformation under pressure. When the building is subjected to vertical vibration, the upper mounting plate connected to the building column will shift vertically relative to the building foundation. When the building column moves the mounting plate 107 downward, the mounting plate 107 will axially compress the rubber column 11. The rubber column 11 is elastic, so the mounting plate 107 will be cushioned when it moves downward. When the building column moves the mounting plate 107 upward, the mounting plate 107 moves upward, and the included angle between the hinge plate 108 and the hinge plate 209 increases. Due to the presence of the abutment plate 10, multiple abutment plates 10 move closer to the rubber column 11. Multiple abutment plates 10 will compress the side wall of the rubber column 11. When the rubber column 11 is deformed by lateral pressure, it will provide a certain buffer for the building column. Regardless of whether the column moves upward or downward relative to the foundation, the rubber column 11 can buffer the column.

[0029] More specifically, the vibration isolation bearing also includes connecting components, which include an upper connecting plate 13 and a lower connecting plate 14 arranged horizontally. The upper surface of the upper connecting plate 13 is fixed to the building column, and the lower surface of the lower connecting plate 14 is fixed to the building foundation. The upper connecting plate 13 and the lower connecting plate 14 are generally preferably rectangular plates. Mounting holes are provided on the surfaces of both the upper connecting plate 13 and the lower connecting plate 14. The upper connecting plate 13 can be connected to the column, and the lower connecting plate 14 can be connected to the foundation by bolts. The end of the support column 1 04 away from the circular plate 03 is vertically fixed to the lower surface of the upper connecting plate 13. The lower surface of the mounting plate 2 16 is tightly fixed to the upper surface of the lower connecting plate 14.

[0030] More specifically, the horizontal vibration isolation component also includes a circular shim 06. The shim 06 has an opening in its central area. The shim 06 is coaxially sleeved on the support column 04. The upper and lower surfaces of the shim 06 slide and fit tightly against the lower surface of the upper connecting plate 13 and the upper surface of the cover plate 05, respectively. In this embodiment, the shim 06 is made of wear-resistant material. On the one hand, it ensures that there will be no excessive wear between the upper connecting plate 13 and the cover plate 05. On the other hand, it ensures that the weight of the upper connecting plate 13 and the weight above it will not be concentrated on the support column 04, thus ensuring that the vibration isolation support has good support performance.

[0031] The outer wall of the buffer plate 01 is provided with a filling nozzle 15 that communicates with the annular oil passage 010. Under normal circumstances, the filling nozzle 15 is in a closed state. When it is necessary to inject hydraulic oil into the inner side of the buffer plate 01, the filling nozzle 15 can be opened.

[0032] The end wall of the abutment plate 10 away from the hinge plate 108 is arc-shaped to match the bottom wall of the annular groove 110, ensuring that the end wall of the abutment plate 10 can fully contact the bottom wall of the annular groove 110.

[0033] The inner diameter of the buffer groove 013 is larger than the outer diameter of the circular plate 03. The end wall of the slider 02 away from the annular oil passage 010 is arc-shaped to match the side wall of the circular plate 03, and the end wall of the circular plate 03 and the slider 02 can effectively contact each other.

[0034] More specifically, the vertical vibration isolation component also includes a second column 12 with a circular cross-section. The second column 12 is vertically fixed to the upper surface of the second mounting plate 16. The second column 12 is coaxially arranged with the annular oil passage 010. A through hole 111 is centrally opened at the end of the rubber column 11. The second column 12 is coaxially arranged in the through hole 111. The upper end surface of the second column 12 can abut against the lower surface of the first mounting plate 07. The purpose of designing the second column 12 is that when the rubber column 11 is damaged or loses its support due to itself or other reasons, the second column 12 can abut against the first mounting plate 07, that is, to ensure the support performance of the vibration isolation support.

[0035] When in use, the upper connecting plate 13 is fixedly connected to the building's columns, and the lower connecting plate 14 is fixedly connected to the building's foundation. Both the upper connecting plate 13 and the lower connecting plate 14 are installed horizontally. When the building is subjected to lateral vibration, the horizontal vibration isolation component provides lateral buffering for the columns connected to it and the structure above the columns. When the building is subjected to vertical vibration, the vertical vibration isolation component provides vertical buffering for the columns connected to it and the structure above the columns.
