Description

Technical Field

[0001] This utility model relates to the field of damping wall technology, specifically a viscoelastic damping wall. Background Technology

[0002] With the increasing number of modern high-rise buildings, their structures are significantly affected by earthquakes and wind-induced vibrations. Reducing the structural response to these events has become a crucial aspect of structural design. Damping walls, by increasing structural damping and dissipating vibrational energy, are widely used in construction. According to application number CN208564126U, a metal-viscous-viscoelastic composite damper and a metal-viscous-viscoelastic composite damping wall effectively utilize the stiffness support function of the metal damper and viscoelastic damper during minor earthquakes; they also fully utilize the damping energy dissipation characteristics of the viscoelastic and viscous dampers, ensuring energy dissipation capacity during minor earthquakes; and during major earthquakes, they fully utilize the damping energy dissipation characteristics of the metal damper, ensuring that the energy dissipation capacity of the composite damper is not reduced due to the attenuation of energy dissipation in the viscoelastic and viscous dampers. Although the upper end of the intermediate plate 42 protrudes from the upper end of the viscoelastic material plate 51, and upper clamping plates 56 are provided on both sides of the protruding part, with the bottom surface of the upper clamping plate 56 in contact with the upper end surface of the viscoelastic material plate 51 to prevent silicone oil from contacting the viscoelastic material plate 51, after long-term use and friction, the contact surface will be damaged. Since the silicone oil and the viscoelastic material plate 51 are installed in the same cavity, the silicone oil will come into contact with the viscoelastic material plate, which may allow the low molecular weight components in the silicone oil to penetrate into the viscoelastic material, destroy its molecular chain structure, and cause the material hardness to decrease, elasticity to weaken, or mechanical properties to decline. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a viscoelastic damping wall that solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a viscoelastic damping wall, comprising a viscoelastic damping box, with viscous damping boxes fixedly connected to both sides of the viscoelastic damping box. Mounting seats are placed on the top of both the viscoelastic and viscous damping boxes. Several viscoelastic plates are placed below one mounting seat in the middle, and several viscous plates are placed below the mounting seats on both sides. Mounting plates are fixedly connected to the front and rear ends of the mounting seats. Spacers are inserted between the mounting plates and the viscous plates, between the viscous plates, between the mounting plates and the viscoelastic plates, and between the viscoelastic plates. Second bolts are placed on one side of each mounting plate. One end of one set of second bolts passes through the mounting plate, the viscous plates, and the spacers and extends to the outside of the mounting plate. Another set of second bolts also passes through the mounting plate, the viscoelastic plates, and the spacers and extends to the outside of the mounting plate. A second nut is threaded onto the outside of one end of each second bolt.

[0005] Preferably, a plurality of viscoelastic material plates are welded to the bottom of the inner cavity of the viscoelastic damping box. The positions of the viscoelastic material plates correspond to the viscoelastic plate and the gap between the viscoelastic plate and the mounting plate. Viscoelastic damping material blocks are bonded to the surface of each viscoelastic material plate.

[0006] Preferably, both the viscous damping box and the viscoelastic damping box are fixedly connected to a base at their bottoms, and a fixing seat is placed at the bottom of the base and the top of the mounting seat. A connecting plate is fixedly connected to one end of each fixing seat, and several insertion holes are provided on each connecting plate.

[0007] Preferably, a first sleeve block is fixedly connected to the outer side of both the mounting base and the base, and a second sleeve block is fixedly connected to the outer side of both the mounting base and the first sleeve block is inserted into the interior of both sleeve blocks.

[0008] Preferably, one end of each of the first bolts extends to the outside of the second sleeve block, and a first nut is threaded onto the outside of one end of each of the first bolts.

[0009] Preferably, the bottom of the mounting base and both ends of the mounting plate are fixedly connected to a blocking block.

[0010] This invention provides a viscoelastic damping wall with the following beneficial effects:

[0011] 1. This viscoelastic damping wall, by incorporating both a viscoelastic damping box and a viscous damping box, separates the viscoelastic and viscous damping components. This prevents contact between the silicone oil and the viscoelastic material blocks on the surface of the viscoelastic material plate, and avoids the possibility of low-molecular-weight components in the silicone oil penetrating into the interior of the viscoelastic material, damaging its molecular chain structure, and leading to a decrease in material hardness, weakened elasticity, or deterioration of mechanical properties. Furthermore, it utilizes both viscoelastic and viscous damping to absorb vibrations.

[0012] 2. This viscoelastic damping wall, by setting two fixed seats, a viscoelastic damping box and a viscous damping box, when it is necessary to replace the viscous damping box or the viscoelastic damping box, unscrew the first nut from one end of the first bolt, and then remove the viscoelastic damping box or the viscous damping box from the upper beam and the lower beam. Then, place the new viscous damping box or the new viscoelastic damping box between the lower fixed seat and the upper fixed seat, and then pass one end of the first bolt through the first sleeve block and the second sleeve block and out to the outside of the second sleeve block. Then, screw the first nut on the outside of one end of the first bolt to complete the replacement of the viscous damping box or the viscoelastic damping box. Thus, the viscoelastic damping and viscous damping components can be replaced individually. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution: a viscoelastic damping wall, including a viscoelastic damping box 1, with viscous damping boxes 2 fixedly connected to both sides of the viscoelastic damping box 1. Mounting seats 3 are placed on the top of both the viscoelastic damping box 1 and the viscous damping boxes 2. Several viscoelastic plates 15 are placed below one of the mounting seats 3 in the middle, and several viscous plates 17 are placed below the mounting seats 3 on both sides. Mounting plates 10 are fixedly connected to the frontmost and rearmost ends of the mounting seats 3. The mounting plates 10 and viscous plates 17, as well as the spaces between the mounting plates 10 and the viscous plates 17, and between the mounting plates 10 and the viscoelastic plates 15, are connected. Spacers 11 are inserted between each viscoelastic plate 15. Second bolts 12 are placed on one side of each mounting plate 10. One end of one set of second bolts 12 passes through the mounting plate 10, viscoelastic plate 17, and spacers 11 and extends to the outside of the mounting plate 10. One end of another set of second bolts 12 passes through the mounting plate 10, viscoelastic plate 15, and spacers 11 and extends to the outside of the mounting plate 10. A second nut 13 is threaded to the outside of one end of each second bolt 12. A pouring gate is opened on the surface of each viscoelastic damping box 2 for adding silicone oil into the viscoelastic damping box 2 and then sealing the pouring gate.

[0019] Several viscoelastic material plates 14 are welded to the bottom of the inner cavity of the viscoelastic damping box 1. The positions of the multiple viscoelastic material plates 14 correspond to the viscoelastic plate 15 and the gap between the viscoelastic plate 15 and the mounting plate 10. Viscoelastic damping material blocks are bonded to the surface of each viscoelastic material plate 14. Viscoelastic damping material blocks are used to dissipate vibration energy.

[0020] Both the viscous damping box 2 and the viscoelastic damping box 1 are fixedly connected to a base 16. The bottom of the base 16 and the top of the mounting base 3 are both equipped with a fixing seat 4. One end of the fixing seat 4 is fixedly connected to a connecting plate 5. Several insertion holes are provided on the connecting plate 5. The fixing seat 4 can be installed on the upper beam and the lower beam by bolts through the insertion holes.

[0021] The mounting base 3 and the base 16 are both fixedly connected to the outer side of the first sleeve block 6, and the fixed base 4 is fixedly connected to the outer side of the second sleeve block 7. The first sleeve block 6 is inserted with a first bolt 8. The mounting base 3, the upper fixed base 4, the viscoelastic damping box 1, the viscous damping box 2 and the lower fixed base 4 are fixed by the first bolt 8, the second sleeve block 7 and the first sleeve block 6.

[0022] One end of the first bolt 8 extends to the outside of the second sleeve block 7. The outside of one end of the first bolt 8 is threaded with a first nut 9. The viscoelastic damping box 1 and the viscous damping box 2 are installed by the cooperation of the first nut 9 and the first bolt 8.

[0023] The bottom of the mounting base 3 and both ends of the mounting plate 10 are fixedly connected to the blocking blocks 18, which block the top of the viscoelastic damping box 1 and the viscous damping box 2.

[0024] In summary, when using this viscoelastic damping wall, two fixed seats 4 are installed on the upper and lower beams with bolts. Then, the viscoelastic damping box 1 and the viscous damping box 2 are placed between the lower fixed seat 4 and the upper fixed seat 4. Then, one end of the first bolt 8 passes through the first sleeve block 6 and the second sleeve block 7 and extends to the outside of the second sleeve block 7. Then, the first nut 9 is screwed on the outside of one end of the first bolt 8. When the building vibrates, the viscoelastic plate 15 moves inside the viscoelastic damping box 1. Friction is caused by the contact between the viscoelastic plate 15 and the viscoelastic damping material block on the surface of the viscoelastic material plate 14. The friction generates heat energy to dissipate the energy of the earthquake. Due to the large contact area, the friction is also large, and its energy dissipation effect is better.

[0025] The silicone oil filling the viscous damping box 2 causes shear deformation at the parts of the mounting plate 10 that come into contact with the silicone oil, and the shear deformation dissipates the seismic energy.

[0026] When it is necessary to replace the viscous damping box 2 or the viscoelastic damping box 1, unscrew the first nut 9 from one end of the first bolt 8, and then remove the viscoelastic damping box 1 or the viscous damping box 2 from the upper beam and the lower beam. Then, place the new viscous damping box 2 or the new viscoelastic damping box 1 between the lower fixed seat 4 and the upper fixed seat 4. Then, pass one end of the first bolt 8 through the first sleeve block 6 and the second sleeve block 7 and out to the outside of the second sleeve block 7. Then, screw the first nut 9 on the outside of one end of the first bolt 8 to complete the replacement of the viscous damping box 2 or the viscoelastic damping box 1. The dimensions of the viscoelastic damping box 1 and the viscous damping box 2 can be adjusted according to requirements during production.

[0027] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The installation methods between equipment are also the same as conventional installation methods in the prior art. For example, the two ends of the shaft-shaped parts are connected by bearings, the connection position of the valve component is provided with anti-leakage rubber strips, the outside of the threaded rod or screw is provided with dust cover, and the equipment can be driven by either built-in battery or external power supply. The control method is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, this utility model will not explain the control method and circuit connection in detail. The external controller mentioned in the specification can play a control role for the electrical components mentioned in this article, and the external controller is a conventional known device.
