Description
Technical Field
[0001] This utility model relates to rubber supports, and more particularly, to a height-adjustable rubber support. Background Technology
[0002] Currently, Chinese patent CN220643844U discloses a self-resetting high-damping vibration-damping rubber bearing, including an upper bearing steel plate and a lower bearing steel plate. The bottom of the upper bearing steel plate is provided with an upper bearing sealing plate, and the upper surface of the lower bearing steel plate is provided with a lower bearing sealing plate. Multiple curved steel plates are provided between the upper and lower bearing sealing plates, and adjacent components form a convex-concave contact surface. The upper bearing sealing plate, the alternately stacked curved steel plate layers and rubber layers, and the lower bearing sealing plate are vulcanized into an integral bearing under high temperature and high pressure. This application has a reasonable structure, increases the constraint force of the steel plate on the rubber layer, can provide much greater stiffness and damping than ordinary rubber bearings, and has a strong ability to adapt to rotational deformation, has a good self-resetting function, and has a good vibration reduction and isolation effect.
[0003] However, if the foundation of a seismic isolation building using horizontal rubber bearings settles after an earthquake, causing some bearings to have reduced bearing capacity or even be in a tensile state, it will affect the mechanical stability of the building's isolation layer and the overall stress of the building, severely restricting the performance of the rubber bearings and reducing the seismic isolation effect. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a height-adjustable rubber bearing to improve the vibration isolation effect.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a height-adjustable rubber support, including a rubber support body, an upper flange plate, and a lower flange plate. The upper flange plate and the lower flange plate are respectively fixed to the upper end and the lower end of the rubber support body. The upper flange plate is fixedly connected to the load. It also includes an adjusting column, an upper support plate, and a lower support plate. The upper support plate is connected to the load, and the lower support plate is connected to the foundation. The adjusting column rotates and moves the upper support plate away from or towards the lower support plate through a transmission component. The lower flange plate is fixedly connected to the foundation through an adjustable component, and a pad is provided between the lower flange plate and the foundation.
[0006] To achieve the above technical solution, the adjusting column is rotated, and the upper support plate is moved away from the lower support plate via the transmission component, thus separating the lower flange plate from the foundation. A pad is then placed between the foundation and the lower flange plate. Subsequently, the upper support plate, lower support plate, and adjusting column are disassembled. Finally, the adjustable component is used to fix the lower flange plate to the foundation. At this point, the pad raises the height of the rubber bearing body, thereby improving the seismic isolation effect.
[0007] In a preferred embodiment of this utility model, the conductive component includes a first threaded segment, a second threaded segment, a first nut, and a second nut. The first threaded segment and the second threaded segment are respectively fixed to both ends of the adjusting column. The first threaded segment and the second threaded segment rotate in opposite directions. The first nut is connected to the upper support plate, the second nut is connected to the lower support plate, the first threaded segment is threadedly connected to the first nut, and the second threaded segment is threadedly connected to the second nut.
[0008] To achieve the above technical solution, the adjusting column is rotated forward, and through the transmission effect of the thread, the first nut moves closer to the upper support plate, while the second nut moves closer to the lower support plate, so that the lower flange plate is separated from the foundation. After the pad is placed between the lower flange plate and the foundation, the adjusting column is rotated in the reverse direction, and the upper and lower support plates move closer to each other, so that the pad is pressed against the foundation, thereby allowing the upper support plate, lower support plate, and adjusting column to be removed.
[0009] As a preferred embodiment of the present invention, the outer wall of the first nut is provided with a plurality of first planes, and the upper support plate is provided with a first groove for embedding the first nut.
[0010] To achieve the above technical solution, when the adjusting column is rotated, the first plane abuts against the inner wall of the first groove to restrict the rotation between the first nut and the upper support plate, so that the adjusting column can drive the first nut to move more smoothly.
[0011] As a preferred embodiment of the present invention, the outer wall of the second nut is provided with a plurality of second planes, and the lower support plate is provided with a second groove for embedding the second nut.
[0012] To achieve the above technical solution, when the adjusting column is rotated, the second plane abuts against the inner wall of the second groove to restrict the rotation between the second nut and the lower support plate, so that the adjusting column can drive the second nut to move more smoothly.
[0013] As a preferred embodiment of this utility model, an external hexagonal ring is fixed on the adjusting column, and the external hexagonal ring is coaxially arranged with the adjusting column.
[0014] To achieve the above technical solution, a special tooling is used in conjunction with an external hexagonal ring to facilitate the rotation of the adjusting column.
[0015] As a preferred embodiment of this utility model, both the upper support plate and the lower support plate are provided with placement arc surfaces, and the edges of the upper flange plate and the lower flange plate are located in the placement arc surfaces.
[0016] The above technical solution is implemented so that the adjusting column is closer to the upper flange plate and the lower flange plate, making it more stable during the process of raising the upper support plate.
[0017] As a preferred embodiment of this utility model, the adjustable component includes a locking bolt and a step pre-embedded sleeve. The step pre-embedded sleeve includes an integrated pre-embedded section and a connecting section. The outer diameter of the pre-embedded section is larger than the outer diameter of the connecting section. The lower flange plate has a connecting hole. The pre-embedded section is fixed to the foundation. The connecting section passes through the connecting hole. The locking bolt is threadedly connected to the step pre-embedded sleeve and abuts against the lower flange plate.
[0018] To achieve the above technical solution, before raising the lower flange plate, the locking bolt is unscrewed from the pre-embedded sleeve of the step. After the lower flange plate is raised to a suitable height, the connecting hole moves upward along the connecting section, and the pad is placed between the lower flange plate and the foundation. Then, the locking bolt is threaded onto the pre-embedded sleeve of the step, so that the locking bolt abuts against the upper surface of the lower flange plate, thereby achieving a fixed connection between the lower flange plate and the foundation.
[0019] As a preferred embodiment of the present invention, the adjustable component further includes a washer ring, which is sleeved on the locking bolt and abuts against the locking bolt on one side and against the lower flange plate on the other side. The outer diameter of the washer ring is larger than the outer diameter of the locking bolt.
[0020] The above technical solution is implemented to make the connection between the adjusting bolt and the lower flange plate tighter.
[0021] As a preferred embodiment of this utility model, the upper support plate, the lower support plate, and the two adjusting columns constitute an adjusting assembly, and the four adjusting assemblies are evenly distributed along the axis of the rubber support body.
[0022] The above technical solution makes the process of raising the lower and upper flange plates by the adjustment components smoother; at the same time, it makes the support of the eight adjustment columns on the load more stable. Attached Figure Description

[0030] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.
[0031] A height-adjustable rubber bearing includes a rubber bearing body 1, an upper flange plate 11, and a lower flange plate 12. The upper flange plate 11 and the lower flange plate 12 are respectively fixed to the upper and lower ends of the rubber bearing body 1. The upper flange plate 11 is fixedly connected to the load 21 using expansion bolts.
[0032] The upper support plate 31 is connected to the load-bearing object 21, and the lower support plate 32 is connected to the foundation 22. Arcade surfaces 33 are provided on the side walls of both the upper and lower support plates 31 and 32. The edges of the upper flange plate 11 and the lower flange plate 12 are located within the arc surfaces 33. The upper support plate 31 abuts against the load-bearing object 21, and the lower support plate 32 abuts against the foundation 22.
[0033] The adjusting column 4 is located between the upper support plate 31 and the lower support plate 32. Rotating the adjusting column 4 causes the upper support plate 31 to move away from or towards the lower support plate 32 via the transmission assembly 5.
[0034] An upper support plate 31, a lower support plate 32, and two adjusting columns 4 constitute an adjusting assembly. The four adjusting assemblies are evenly distributed along the axis of the rubber support body 1.
[0035] The transmission assembly 5 includes a first threaded section 51, a second threaded section 52, a first nut 53, and a second nut 54. The first threaded section 51 and the second threaded section 52 are respectively fixed to both ends of the adjusting column 4, and are coaxially arranged. The first threaded section 51 and the second threaded section 52 rotate in opposite directions.
[0036] The first nut 53 is connected to the upper support plate 31, and the second nut 54 is connected to the lower support plate 32. The first threaded section 51 is threadedly connected to the first nut 53, and the second threaded section 52 is threadedly connected to the second nut 54.
[0037] Six first planes 55 are formed on the outer wall of the first nut 53, and the six first planes 55 are evenly distributed along the axis of the first nut 53. The upper support plate 31 has a first groove 56 for embedding the first nut 53. The cross-section of the first groove 56 is a regular hexagon, so that the first nut 53 and the upper support plate 31 are not prone to large-scale rotation.
[0038] The outer wall of the second nut 54 has six second planes 57, which are evenly distributed along the axis of the second nut 54. The lower support plate 32 has a second groove 58 for embedding the second nut 54. The cross-section of the second groove 58 is a regular hexagon to prevent the second nut 54 from rotating too much with respect to the lower support plate 32.
[0039] An external hexagonal ring 41 is fixed in the middle of the adjusting column 4, and the external hexagonal ring 41 is coaxially arranged with the adjusting column 4.
[0040] Accordingly, the upper support plate 31 and the lower support plate 32 are positioned to prevent relative rotation between the upper support plate 31 and the load 21, and to prevent relative rotation between the lower support plate 32 and the foundation 22. By clamping a special tool such as a wrench onto the outer wall of the outer hexagonal ring 41, the adjusting column 4 is rotated clockwise. Through the transmission action of the thread, the first nut 53 moves closer to the upper support plate 31, and the second nut 54 moves closer to the lower support plate 32, thereby lifting the lower flange plate 12 off the foundation 22.
[0041] A pad 6 is provided between the lower flange plate 12 and the foundation 22. The pad 6 is made of steel plate.
[0042] Then, the adjusting column 4 is rotated in the opposite direction. Similarly, the upper support plate 31 and the lower support plate 32 are moved closer to each other, so that one side of the pad 6 abuts against the lower flange plate 12 and the other side of the pad 6 abuts against the foundation 22. This allows the upper support plate 31, the lower support plate 32, and the adjusting column 4 to be removed.
[0043] Finally, the lower flange plate 12 is fixedly connected to the foundation 22 via the adjustable assembly 7. The adjustable assembly 7 includes a locking bolt 71 and a stepped embedded sleeve 72. The stepped embedded sleeve 72 includes an integrated embedded section 721 and a connecting section 722. The embedded section 721 and the connecting section 722 are coaxially arranged. The outer diameter of the embedded section 721 is larger than the outer diameter of the connecting section 722. A connecting hole 9 is provided in the lower flange plate 12, and the embedded section 721 is fixed to the foundation 22. The connecting section 722 passes through the connecting hole 9, and the locking bolt 71 is threadedly connected to the stepped embedded sleeve 72, with the locking bolt 71 abutting against the lower flange plate 12.
[0044] The adjustable component 7 also includes a washer 8. The washer 8 is fitted onto the locking bolt 71 and abuts against the locking bolt 71 on one side and against the lower flange plate 12 on the other side. The outer diameter of the washer 8 is larger than the outer diameter of the locking bolt 71.
[0045] This utility model has the following features:
[0046] When adjusting, eight adjusting pins 4 are placed at the four corners of the rubber support body 1 to lift it. The threads between the first threaded section 51 and the second threaded section 52 are opposite in direction, so that it can be lifted or contracted when rotated in one direction.
[0047] The two ends of the adjusting column 4 are threadedly connected to the first nut 53 and the second nut 54 respectively to transmit vertical load.
[0048] After the rubber bearing body 1 is lifted using the adjusting column 4, a pad 6 is inserted between the rubber bearing body 1 and the lower flange plate 12 to raise it. The pad 6 and the adjusting column 4 are temporary structures that can be removed after the height adjustment without affecting the seismic isolation performance of the rubber bearing body 1.
[0049] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
