Description

Technical Field

[0001] The present application relates to the technical field of building seismic isolation, and in particular to a viscous shock-absorbing and damping wall. Background Art

[0002] Viscous shock-absorbing damping wall is an energy-absorbing shock absorber used in building structures. Its working principle is based on the viscous energy dissipation of materials and the elastic-plastic energy dissipation of metals to consume seismic energy, thereby reducing the vibration amplitude of the building and improving its earthquake resistance.

[0003] Viscous shock-absorbing damping wall is a shock-absorbing device widely used in engineering structures such as buildings and bridges. It generates viscous resistance through the flow of damping fluid in the damping cavity, thereby consuming the energy generated by external excitations such as earthquakes or wind vibrations to achieve the effect of shock absorption. However, this damping method has an obvious limitation, that is, the magnitude of the damping force mainly depends on the viscosity of the damping fluid and the structural design of the damping cavity, and once the design is completed, the magnitude of the damping force is basically fixed and difficult to adjust according to actual conditions.

[0027] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0029] The present application embodiment provides a viscous shock-absorbing damping wall, such as Figure 1 As shown, the viscous shock-absorbing damping wall may include a steel box 1, a damping plate 4, an upper connecting member 5, a lower connecting member 6, a plurality of slots 7, a plurality of clearance slots 8, a damping assembly and a driving assembly;

[0030] Among them, the steel box 1 is hollow inside to form a damping chamber 3, and the damping chamber 3 passes through one end of the steel box 1 to form a guide port 2; the damping plate 4 is slidably installed in the damping chamber 3 through the guide port 2; the upper connecting member 5 is fixedly installed at the end of the damping plate 4 located outside the damping chamber 3; the lower connecting member 6 is fixedly installed at the end of the steel box 1 opposite to the guide port 2; a number of slots 7 are symmetrically arranged in two rows on the outer walls of the damping plate 4 on both sides along the thickness direction; a number of clearance grooves 8 are symmetrically arranged in groups of two on the outer walls of the damping plate 4 on both sides along the thickness direction, and the clearance grooves 8 are respectively located above the slots 7 close to the upper connecting member 5; the damping assembly is arranged in one-to-one correspondence with the number of clearance grooves 8, and part of the structure of the damping assembly is located in the corresponding slot 7, and part of the structure is located in the corresponding clearance groove 8; the driving assembly is arranged on the inner wall of the steel box 1 corresponding to the clearance groove 8, and is adapted to the damping assembly.

[0031] Specifically, the steel box 1 is hollow inside to form a damping chamber 3, and the damping chamber 3 passes through one end of the steel box 1 to form a guide opening 2 for guiding the movement of the damping plate 4, and a sealing mechanism is provided in the guide opening 2 to seal the guide opening 2. The sealing mechanism is an existing mature technology and will not be described in detail herein and is not shown in the figure; the damping chamber 3 can be used to hold liquid for shock absorption.

[0032] The damping plate 4 is slidably installed in the damping chamber 3 through the guide opening 2. The damping plate 4 can generate a damping force during its movement to achieve shock absorption.

[0033] The upper connecting member 5 is fixedly mounted on one end of the damping plate 4 located outside the damping chamber 3, and the upper connecting member 5 can be connected to the upper wall;

[0034] The lower connecting piece 6 is fixedly mounted on the end of the steel box 1 opposite to the guide opening 2, and the lower connecting piece 6 can be connected to the wall at the bottom for firm use;

[0035] A plurality of slots 7 are symmetrically arranged in two rows on the outer walls of both sides of the damping plate 4 along the thickness direction. The slots 7 are symmetrically arranged on both sides of the damping plate 4 to provide installation positions for the damping baffle 10 mentioned in the subsequent embodiments, so as to facilitate the deployment of the damping baffle 10;

[0036] A plurality of clearance grooves 8 are symmetrically arranged in groups of two on the outer walls of both sides of the damping plate 4 along the thickness direction, and the clearance grooves 8 are respectively located above the slots 7 close to the upper connecting member 5, and the clearance grooves 8 on both sides of the damping plate 4 are symmetrically arranged at the corners of the slots 7 at both ends;

[0037] Please combine Figure 2 and Figure 3For reference, the damping assembly is arranged in one-to-one correspondence with the plurality of clearance grooves 8, part of the structure of the damping assembly is located in the corresponding slot 7, and part of the structure is located in the corresponding clearance groove 8, and the damping assembly can increase the damping force during the movement of the damping plate 4 for adjustment;

[0038] Please combine Figure 4 and Figure 5 For reference, the driving assembly is arranged on the inner wall of the steel box 1 corresponding to the clearance groove 8, and is adapted to the damping assembly. The driving assembly can be used in conjunction with the damping assembly to realize the deployment of the damping baffle, thereby increasing the damping force to achieve a better shock absorption effect.

[0039] The movement of the damping plate 4 in the damping chamber 3 combined with the expansion of the damping assembly can more effectively contact the damping fluid, thereby increasing the damping force and achieving a better shock absorption effect. The damping assembly can be expanded as needed during the movement of the damping plate 4, thereby dynamically adjusting the magnitude of the damping force to cope with different vibration requirements. The damping force is controllable and adjustable through the setting of the damping assembly, and the entire structure is easy to manufacture and maintain.

[0040] In one embodiment, the damping chamber 3 is filled with viscous fluid.

[0041] It is understandable that a viscous fluid such as silicone oil or high molecular viscous liquid can provide additional damping effect, and the flow of the viscous fluid can be regulated by the movement of the damping plate 4, thereby achieving effective absorption and dissipation of external vibrations.

[0042] In one embodiment, the outer walls of the steel box 1, the damping plate 4, the upper connecting member 5 and the lower connecting member 6 are all provided with a protective layer.

[0043] It is understood that the protective layer is made of corrosion-resistant and fire-resistant materials to improve the overall durability and safety of the damping wall. In addition, a number of heat dissipation holes are provided on the protective layer to ensure the heat dissipation effect of the damping wall during long-term operation and avoid performance degradation or damage caused by overheating.

[0044] In one embodiment, the damping plate 4 is made of elastic polymer material.

[0045] It is understandable that the use of a polymer material with a certain elasticity can ensure that the damping plate 4 has good wear resistance and resilience during the sliding process, thereby extending its service life and improving the shock absorption effect.

[0046] Specifically, the damping wall is installed to the use position through the upper connecting member 5 and the lower connecting member 6. During use, the damping plate 4 can move in the damping chamber 3 to generate a damping force to achieve shock absorption. At the same time, during the movement of the damping plate 4, the damping assembly can be deployed in cooperation with the driving assembly to increase the damping force.

[0047] Please continue to combine Figure 2 and Figure 3 For reference, in an exemplary embodiment, the damping assembly may include a rotating shaft 9, a plurality of damping baffles 10, and a driven wheel 11, wherein one end of the rotating shaft 9 extends into the clearance groove 8, and the other end passes through a plurality of corresponding slots 7 and is rotatably installed in the slot 7 close to the lower connecting member 6; a plurality of damping baffles 10 are arranged at a plurality of slots 7, and a screw hole is provided on the side of the damping baffle 10 facing the corresponding rotating shaft 9, and the damping baffle 10 is rotatably matched with the corresponding rotating shaft 9 through the screw hole; the driven wheel 11 is fixedly installed at one end of the rotating shaft 9 located in the clearance groove 8.

[0048] Specifically, during the movement of the damping plate 4, the driven wheel 11 can rotate under the action of the driving assembly, thereby driving the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it can drive the damping baffle 10 to rotate out of the slot 7, and the expansion direction of the damping baffle 10 is the moving direction of the damping plate 4. Therefore, the damping baffle 10 can be in more complete contact with the damping fluid during the movement of the damping plate 4 to increase the damping force and achieve better shock absorption.

[0049] Please continue to combine Figure 4 , Figure 5 For reference, in an exemplary embodiment, the driving assembly includes a support frame 12, a plurality of vertical plates 13, a clearance opening 14, a threaded sleeve 19, and an adjustment assembly, wherein the support frame 12 is arranged at a position relative to the inner wall of the steel box 1 and the driven wheel 11; a plurality of vertical plates 13 are distributed in a linear array and fixedly installed at the open end of the support frame 12; the clearance opening 14 is arranged between two adjacent vertical plates 13; the threaded sleeve 19 is fixedly installed between the support frame 12 and the opposite side of the steel box 1; and the adjustment assembly is arranged in the support frame 12 and the threaded sleeve 19.

[0050] Specifically, the initial position of the support frame 12 is set at a position opposite to the two driven wheels 11. Since the damping plate 4 can only move in one direction at a time, Figure 2 Taking the direction as an example, when the damping plate 4 moves to the left, the driven wheel 11 on the right can contact the vertical plate 13 on the right support frame 12, while the driven wheel 11 on the left cannot contact the support frame 12 when the damping plate 4 moves to the left due to the setting of the support frame 12. Therefore, the damping baffle 10 on the right can be unfolded under the action of the driven wheel 11 and the rotating shaft 9 to increase the damping force.

[0051] Please combine Figure 4 , Figure 5For reference, in an exemplary embodiment, the adjustment assembly includes a slide plate 15, a plurality of support blocks 16, and an adjustment screw 17, wherein the slide plate 15 is slidably installed in the support frame 12; a plurality of support blocks 16 are distributed in a linear array and fixedly installed on a side of the slide plate 15 opposite to the vertical plate 13; the adjustment screw 17 is rotatably installed on an end of the slide plate 15 away from the support block 16, and the end of the adjustment screw 17 away from the slide plate 15 passes through a threaded sleeve 19 and the steel box 1, and the adjustment screw 17 is threadedly connected to the threaded sleeve 19.

[0052] Furthermore, a handle 18 is fixedly mounted on one end of the adjusting screw 17 located outside the steel box 1 .

[0053] Specifically, the handle 18 is located outside the steel box 1 . When the deployment angle of the damping baffle 10 needs to be adjusted, the handle 18 can be rotated to drive the adjusting screw 17 to adjust the angle of the damping baffle 10 .

[0054] In one embodiment, the cross-sectional dimension of the support block 16 is the same as the cross-sectional dimension of the clearance opening 14 , and the support block 16 and the clearance opening 14 are disposed opposite to each other.

[0055] It is understandable that when the support block 16 moves to the middle of the clearance opening 14 , it can fit with the clearance opening 14 so as to frictionally drive the driven wheel 11 .

[0056] In one embodiment, the driven wheel 11 , the vertical plate 13 and the support block 16 are all provided with anti-slip grooves.

[0057] It can be understood that the anti-skid pattern can increase the surface area during contact so as to increase the friction force, thereby preventing the driven wheel 11 from idling.

[0058] Specifically, in the initial state, the support block 16 is located in the clearance opening 14 and is flush with the vertical plate 13. At this time, when the driven wheel 11 rotates, it can contact the vertical plate 13 and the support block 16 to produce maximum rotation. If it is necessary to adjust the expansion angle of the damping baffle 10, the adjusting screw 17 can be rotated. When the adjusting screw 17 rotates, the slide plate 15 slides on the inner wall of the support frame 12, and the adjusting screw 17 is threadedly connected to the threaded sleeve. Therefore, when the adjusting screw 17 rotates, the slide plate 15 can slide along the inner wall of the support frame 12. At this time, the support block 16 can slide out of the clearance opening 14, and the driven wheel 11 can only contact the vertical plate 13. Therefore, when the driven wheel 11 rotates, the expansion angle of the damping baffle 10 is limited, thereby realizing the adjustment of the damping force.

[0059] The viscous shock-absorbing damping wall proposed in the embodiment of the present application, the movement of the damping plate 4 in the damping chamber 3 is combined with the deployment of the damping assembly, which can more effectively contact the damping fluid, thereby increasing the damping force and achieving a better shock-absorbing effect. The damping baffle 10 can be deployed as needed during the movement of the damping plate 4, thereby dynamically adjusting the magnitude of the damping force to cope with different vibration requirements. Through the simple combination of the driven wheel 11, the rotating shaft 9 and the damping baffle 10, the controllable adjustment of the damping force is achieved, and the entire structure is easy to manufacture and maintain.

[0060] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
