A displacement type viscous damping wall

Abstract

This utility model discloses a displacement-type viscous damping wall, comprising a steel box wall and a connecting wall. A damping liquid cavity is formed inside the steel box wall. A movable steel plate is fixedly connected to the bottom surface of the steel box wall and inserted into the damping liquid cavity. A rubber sealing plate is fixed to the outer surface of the movable steel plate, and the outer surface of the rubber sealing plate is fixed to the inner wall of the damping liquid cavity. This utility model, through a surrounding support strip, enhances the support while increasing the damping capacity of the damping wall. When the upper and lower walls have a large range of motion, the bottom support rod cooperates with the support seat. Under significant pressure, the upper and lower walls can maintain sufficient support while increasing the available space, preventing excessive wall displacement and deformation that could lead to safety issues. This solves the problem of insufficient support and poor stability in existing displacement-type viscous damping walls, improving the overall support and stability of the displacement-type viscous damping wall.

Description

Technical Field

[0001] This utility model relates to the field of viscous damping wall technology, and in particular to a displacement-type viscous damping wall. Background Technology

[0002] A viscous damping wall is a type of damping system where a steel plate moves within a closed, high-viscosity damping fluid (a hydrocarbon polymer). This movement causes the fluid to undergo shear deformation, generating a viscous damping force. During this shear deformation process, the damping material consumes a significant amount of energy, converting the mechanical energy of the structural vibration into heat energy, which is then dissipated, thereby reducing the structure's vibration response.

[0003] To provide sufficient damping force, most viscous damping walls use a combination of high-viscosity damping fluid and damping rubber. However, this type of connection can lead to insufficient support between the two walls, resulting in poor stability of the connection. To address this, we propose a displacement-type viscous damping wall. Utility Model Content

[0004] The problem this invention aims to solve is the poor stability caused by insufficient support force of displacement-type viscous damping walls in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a displacement-type viscous damping wall, comprising a steel box wall and a connecting wall. A damping liquid cavity is formed inside the steel box wall. A movable steel plate is fixedly connected to the bottom surface of the connecting wall. The movable steel plate is inserted into the damping liquid cavity. A rubber sealing plate is fixed to the outer surface of the movable steel plate, and the outer surface of the rubber sealing plate is fixed to the inner wall of the damping liquid cavity. A rubber pad is fixed between the bottom of the movable steel plate and the bottom of the damping liquid cavity. Fixing plates are detachably connected to the outer surfaces of both the connecting wall and the steel box wall. Several rubber strips are equidistantly fixed between each group of two fixing plates. Several support parts are provided at the bottom of the movable steel plate.

[0006] As a preferred embodiment of the displacement-type viscous damping wall of this utility model, the support part includes a movable groove, a support seat and a support rod. Several movable grooves are equidistantly opened at the bottom of the movable steel plate and inside the rubber pad. A support seat is fixed inside each movable groove. The bottom surface of each support seat is fixed to the bottom of the damping liquid cavity. A support rod is provided at the top of each movable groove. Each support rod is fixed to the bottom of the movable steel plate.

[0007] As a preferred embodiment of the displacement-type viscous damping wall of this utility model, a number of base connecting plates are fixed on the bottom surface of the steel box wall and the top surface of the connecting wall, and a number of connecting steel bars are fixed at equal intervals on the side of the base connecting plate away from the steel box wall and the connecting wall.

[0008] As a preferred embodiment of the displacement-type viscous damping wall of this utility model, each of the fixed plates is sleeved on the limiting plates at both ends, both limiting plates are fixed on the side wall of the steel box wall, each limiting plate is fixed with a fixing screw at both ends and on the fixed plate, and a fixing nut is threaded on the outer side of each of the two adjacent fixing screws, and each fixing plate is provided with a limiting groove on both sides to cooperate with the limiting plate.

[0009] As a preferred embodiment of the displacement-type viscous damping wall of this utility model, the rubber sealing plate is configured as a rectangle that cooperates with the moving steel plate and the steel box wall, the top surface of the rubber sealing plate is flush with the top surface of the steel box wall, and the damping liquid cavity on the bottom surface of the rubber sealing plate is filled with high viscosity damping liquid.

[0010] In a preferred embodiment of the displacement-type viscous damping wall of this utility model, each of the supports is bowl-shaped, the bottom of each support rod is spherical and extends into the interior of the support, and the diameter of each support rod is smaller than the inner diameter of the support.

[0011] As a preferred embodiment of the displacement-type viscous damping wall of this utility model, each of the fixing screws is a semi-cylinder, and the outer surfaces of each pair of adjacent fixing screws are provided with mutually mating threads.

[0012] The beneficial effects of this utility model are as follows: By using a ring-shaped support strip, this utility model can enhance the support and increase the shock absorption capacity of the damping wall. When the upper and lower walls have a large range of motion, the support rod at the bottom cooperates with the support seat. Under greater pressure, the upper and lower walls can increase the space for movement while ensuring the support force, avoiding excessive displacement and deformation of the wall that could lead to safety problems. This solves the problem of insufficient support force and poor stability of existing displacement-type viscous damping walls, and improves the overall support force and stability of displacement-type viscous damping walls.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Reference Figures 1-4 This embodiment is a displacement-type viscous damping wall, including a steel box wall 1 and a connecting wall 2. A damping liquid cavity 5 is opened inside the steel box wall 1. A movable steel plate 6 is fixedly connected to the bottom surface of the connecting wall 2. The movable steel plate 6 is inserted into the damping liquid cavity 5. A rubber sealing plate 8 is fixed to the outer surface of the movable steel plate 6. The outer surface of the rubber sealing plate 8 is fixed to the inner wall of the damping liquid cavity 5. A rubber pad 7 is fixed between the bottom of the movable steel plate 6 and the bottom of the damping liquid cavity 5. Fixing plates 9 can be detachably connected to the outer surfaces of the connecting wall 2 and the steel box wall 1. Several rubber strips 10 are fixed at equal intervals between each group of two fixing plates 9. Several support parts are provided at the bottom of the movable steel plate 6.

[0020] In this embodiment, the support includes a movable groove 11, a support seat 12, and a support rod 13. Several movable grooves 11 are equidistantly provided at the bottom of the movable steel plate 6 and inside the rubber pad 7. A support seat 12 is fixed inside each movable groove 11. The bottom surface of each support seat 12 is fixed to the bottom of the damping liquid cavity 5. A support rod 13 is provided at the top of each movable groove 11. Each support rod 13 is fixed to the bottom of the movable steel plate 6.

[0021] In this embodiment, several base connecting plates 3 are fixed on the bottom surface of the steel box wall 1 and the top surface of the connecting wall 2. Several connecting steel bars 4 are fixed at equal intervals on the side of the base connecting plate 3 away from the steel box wall 1 and the connecting wall 2, so that the connection between the steel box wall 1 and the connecting wall 2 is more stable and firm.

[0022] In this embodiment, each fixing plate 9 is sleeved on the limiting plate 14 at both ends, and both limiting plates 14 are fixed on the side wall of the steel box wall 1. Each limiting plate 14 and the fixing plate 9 are fixed with fixing screws 15 at both ends, and fixing nuts 16 are threaded on the outer sides of two adjacent fixing screws 15. Each fixing plate 9 has limiting slots 17 on both sides that cooperate with the limiting plate 14.

[0023] In this embodiment, the rubber sealing plate 8 is set as a rectangle that cooperates with the movable steel plate 6 and the steel box wall 1. The top surface of the rubber sealing plate 8 is flush with the top surface of the steel box wall 1. The damping liquid cavity 5 on the bottom surface of the rubber sealing plate 8 is filled with high viscosity damping liquid. The damping liquid inside the damping liquid cavity 5 is sealed by the rubber sealing plate 8, while providing sufficient movement space for the movable steel plate 6.

[0024] In this embodiment, each support 12 is bowl-shaped, and the bottom of each support rod 13 is spherical and extends into the interior of the support 12. The diameter of each support rod 13 is smaller than the inner diameter of the support 12, so that while the support rod 13 abuts against the bottom surface inside the support 12, it can also move around under the action of the moving steel plate 6.

[0025] In this embodiment, each fixing screw 15 is a semi-cylinder, and the outer surfaces of each pair of adjacent fixing screws 15 are provided with mutually cooperating threads to facilitate the fixing of the fixing plate 9 and the limiting plate 14.

[0026] Working principle: When the steel box wall 1 or the connecting wall 2 is subjected to vibration, the moving steel plate 6 moves relative to the damping liquid chamber 5 under the action of vibration. During the movement, the damping liquid moves the steel plate 6, the rubber sealing plate 8, and the rubber strip 10, generating viscous damping force through shear deformation. This converts the mechanical energy of the structural vibration into heat energy, thereby reducing the vibration response of the steel box wall 1 and the connecting wall 2 and protecting them. When the rubber strip 10 ages after long-term use, the fixing nuts 16 on both sides are tightened to release the fixing nuts 16 from the fixing screw 15, allowing the fixing plate 9 to be removed from the limiting plate 14, and then a new... The fixing plate 9 is fitted onto the steel box wall 1 and the connecting wall 2, so that the fixing screw 15 on the new fixing plate 9 is aligned with the fixing screw 15 on the limiting plate 14, and the fixing nut 16 is tightened onto each set of two fixing screws 15 for fixation. During the movement of the moving steel plate 6, when the pressure on the moving steel plate 6 is too great, the support rod 13 moves down under the pressure and abuts against the inner bottom surface of the support seat 12. With the arc design of the support rod 13 and the support seat 12, the horizontal displacement of the steel box wall 1 and the connecting wall 2 can be guaranteed. Thus, after moving down, it provides support force to the support seat 12 while also ensuring the shock absorption effect of the damping wall.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
