Description

Technical Field

[0001] This utility model relates to the technical field of steel plate damping walls, specifically a detachable and replaceable steel plate damping wall. Background Technology

[0002] Steel plate damping walls are passive damping devices that dissipate seismic energy by utilizing the plastic deformation of steel plates. By setting steel plates with low yield strength in the structure, they are made to enter the plastic state first under seismic action, thereby protecting the safety of the main structure.

[0003] Chinese Patent No. 201720129127.2 discloses a fully prefabricated steel plate damping wall, including a fully prefabricated core plate, a fully prefabricated constraint device, and a fully prefabricated connection structure. The fully prefabricated core plate is composed of a series of bending plates with different moduli. Each bending plate is connected in parallel through an upper and lower fully prefabricated connection structure. The bending plates with different moduli have different stiffness and load-bearing capacity. Each bending plate with different moduli has its own fully prefabricated constraint device. The fully prefabricated constraint device is located on both the inner and outer sides of each bending plate and has bolt holes that match the bending plate. The two are connected into a whole by bolts. There is no connection between the fully prefabricated constraint devices of different bending plates.

[0004] The height of this invention cannot be adjusted, making it unsuitable for different environments. Furthermore, installation and disassembly are extremely inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a detachable and replaceable steel plate damping wall to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable and replaceable steel plate damping wall, comprising a steel plate damping wall; the steel plate damping wall is composed of an outer layer plate, an inner layer plate, and a butyl rubber plate, the butyl rubber plate being bonded to both sides of the inner layer plate and the inner side of the outer layer plate, a limiting mechanism being provided between the butyl rubber plate and the both sides of the inner layer plate and the inner side of the outer layer plate, an upper fixing plate being installed at the upper end of the inner layer plate, an mounting plate being installed at the bottom end of the outer layer plate, a bottom fixing plate being provided at the bottom end of the mounting plate, and an adjustment mechanism being installed between the bottom fixing plate and the mounting plate.

[0007] Preferably, the limiting mechanism consists of protrusions and grooves, with the grooves disposed on both sides of the butyl rubber sheet, and the protrusions disposed on both sides of the inner layer plate and the inner side of the outer layer plate, the protrusions being embedded inside the grooves.

[0008] Preferably, soft metal pads are provided on the upper side of the upper fixing plate and below the lower fixing plate, and the soft metal pads are welded to the upper side of the upper fixing plate and below the lower fixing plate.

[0009] Preferably, the adjustment mechanism consists of a support screw and an adjustment nut. The bottom end of the support screw is welded to both sides of the upper end of the bottom fixing plate, the upper end of the support screw passes through the mounting plate, and the adjustment nut is rotatably mounted on the upper side of the support screw at the upper and lower ends of the mounting plate.

[0010] Preferably, a frustum-shaped pile is provided between the support screw and the bottom fixing plate, and the frustum-shaped pile is welded to the bottom end of the support screw and the upper side of the bottom fixing plate.

[0011] Preferably, the outer and inner layers are provided with a corrosion-resistant layer, which is a chromium-plated layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The limiting mechanism can limit the relative displacement between the outer and inner layers when the butyl rubber sheet deforms, preventing damage to the rubber sheet or failure of the damping effect due to excessive displacement. At the same time, the adjustment mechanism can adjust the height of the entire steel plate damping wall to adapt to different environments and facilitate installation.

[0014] 2. The limiting mechanism achieves its function through the interlocking structure of protrusions and grooves. When the outer and inner plates move relative to each other due to vibration, the protrusions on both sides of the inner plate and the inner side of the outer plate will slide along the grooves on both sides of the butyl rubber plate. This sliding fit not only provides guidance for the relative displacement of the plates and prevents the plates from shifting or misaligning, but also limits the maximum displacement through the contact between the protrusions and grooves, avoiding damage to the butyl rubber plate due to excessive stretching or compression, and ensuring the stable operation of the damping wall.

[0015] 3. The soft metal pads on the upper side of the upper fixing plate and the lower side of the bottom fixing plate play a buffering and protective role when the damping wall is working. When the vibration of the building structure is transmitted to the damping wall, the soft metal pads will first bear part of the impact force and absorb part of the vibration energy through their own plastic deformation, reducing the load transmitted to the connection between the fixing plate and the building structure. At the same time, the elasticity of the soft metal pads can also help the fixing plate to return to its original position after the vibration, preventing the connection from loosening or being damaged due to long-term rigid impact, thus extending the service life of the damping wall.

[0016] 4. The adjustment mechanism's support screw and adjusting nut work together to adjust the installation height of the outer layer plate. During installation or maintenance, by rotating the adjusting nuts at both ends of the mounting plate, the mounting plate can be moved up and down along the support screw, thereby changing the position of the outer layer plate. This ensures that a suitable gap is maintained between the outer and inner layers, guaranteeing that the butyl rubber sheet is in optimal working condition. When the damping wall shifts position due to vibration or other reasons, it can also be adjusted using the adjusting nut to restore its normal working performance. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the utility model, a detachable and replaceable steel plate damping wall includes a steel plate damping wall 1. The steel plate damping wall 1 is composed of an outer layer plate 4, an inner layer plate 3, and a butyl rubber plate 2. The butyl rubber plate 2 is bonded to both sides of the inner layer plate 3 and the inner side of the outer layer plate 4. A limiting mechanism 17 is provided between the butyl rubber plate 2, the two sides of the inner layer plate 3, and the inner side of the outer layer plate 4. An upper fixing plate 10 is installed at the upper end of the inner layer plate 3, and an mounting plate 13 is installed at the bottom end of the outer layer plate 4. A bottom fixing plate 9 is provided at the bottom end of the mounting plate 13, and an adjustment mechanism 5 is installed between the bottom fixing plate 9 and the mounting plate 13.

[0025] The limiting mechanism 17 consists of protrusions 16 and grooves 15. The grooves 15 are located on both sides of the butyl rubber sheet 2, and the protrusions 16 are located on both sides of the inner layer 3 and the inner side of the outer layer 4. The protrusions 16 are embedded in the grooves 15. The limiting mechanism 17 achieves its function through the interlocking structure of the protrusions 16 and the grooves 15. When the outer layer 4 and the inner layer 3 move relative to each other due to vibration, the protrusions 16 on both sides of the inner layer 3 and the inner side of the outer layer 4 will slide along the grooves 15 on both sides of the butyl rubber sheet 2. This sliding fit not only provides guidance for the relative displacement of the plates, preventing the plates from shifting or misaligning, but also limits the maximum displacement through the contact between the protrusions 16 and the grooves 15, avoiding damage to the butyl rubber sheet 2 due to excessive stretching or compression, and ensuring the stable operation of the damping wall.

[0026] A soft metal pad 14 is provided on the upper side of the upper fixing plate 10 and below the lower fixing plate 9. The soft metal pad 14 is welded to the upper side of the upper fixing plate 10 and below the lower fixing plate 9. The soft metal pad 14 on the upper side of the upper fixing plate 10 and below the lower fixing plate 9 plays a buffering and protective role when the damping wall is working. When the vibration of the building structure is transmitted to the damping wall, the soft metal pad 14 will first bear part of the impact force and absorb part of the vibration energy through its own plastic deformation, reducing the load transmitted to the connection between the fixing plate and the building structure. At the same time, the elasticity of the soft metal pad 14 can also help the fixing plate to reset after the vibration, avoiding loosening or damage to the connection due to long-term rigid impact, and extending the service life of the damping wall.

[0027] The adjustment mechanism 5 consists of a support screw 6 and an adjustment nut 7. The bottom end of the support screw 6 is welded to both sides of the upper end of the bottom fixing plate 9, and the upper end of the support screw 6 passes through the mounting plate 13. The adjustment nut 7 is rotatably installed on the upper side of the support screw 6 at the upper and lower ends of the mounting plate 13. The support screw 6 and the adjustment nut 7 of the adjustment mechanism 5 cooperate to adjust the installation height of the outer plate 4. During installation or maintenance, by rotating the adjustment nuts 7 at the upper and lower ends of the mounting plate 13, the mounting plate 13 can be moved up and down along the support screw 6, thereby changing the position of the outer plate 4 and ensuring that the outer plate 4 and the inner plate 3 maintain a suitable distance, ensuring that the butyl rubber plate 2 is in the best working condition. When the damping wall shifts position due to vibration or other reasons, it can also be adjusted by adjusting the adjustment nut 7 to restore its normal working performance.

[0028] A frustum-shaped pile 8 is provided between the support screw 6 and the bottom fixing plate 9. The frustum-shaped pile 8 is welded to the bottom end of the support screw 6 and the upper side of the bottom fixing plate 9. The frustum-shaped pile 8 enhances the connection strength between the support screw 6 and the bottom fixing plate 9. When the damping wall is subjected to vibration load, the support screw 6 will be subjected to vertical and horizontal forces. Due to its unique shape, the frustum-shaped pile 8 can evenly distribute the force to the bottom fixing plate 9, reduce stress concentration at the connection point, prevent the weld between the support screw 6 and the bottom fixing plate 9 from breaking, and ensure the structural stability of the adjustment mechanism 5.

[0029] A corrosion-resistant layer 11 is provided on the outer side of the outer layer plate 4 and the inner layer plate 3. The corrosion-resistant layer 11 is a chrome-plated layer. The chrome-plated corrosion-resistant layer 11 on the outer side of the outer layer plate 4 and the inner layer plate 3 can effectively protect the plate body. In humid, dusty or corrosive environments, the chrome-plated layer will form a dense oxide film, which isolates the plate body from the external corrosive media and prevents the steel plate from rusting. This not only maintains the structural strength of the plate body and avoids the reduction of plate thickness and load-bearing capacity due to rust, but also maintains the appearance of the plate body and ensures the normal working performance and service life of the damping wall.

[0030] The working principle and usage process of this utility model are as follows: In the structure of the steel plate damping wall 1, the combination of the outer plate 4, the inner plate 3 and the butyl rubber plate 2 is the core damping unit. When the building structure is subjected to vibration load, the outer plate 4 and the inner plate 3 will generate relative displacement. At this time, the butyl rubber plate 2, due to its high elasticity and viscosity, will absorb and dissipate vibration energy through its own deformation, thereby reducing the vibration response of the structure. The setting of the limiting mechanism 17 can limit the relative displacement amplitude between the outer plate 4 and the inner plate 3 when the butyl rubber plate 2 deforms, so as to avoid damage to the rubber plate or failure of the damping effect due to excessive displacement. The upper fixing plate 10 connects the inner plate 3 to the upper structure of the building, while the mounting plate 13 and the bottom fixing plate 9 fix the outer plate 4 to the lower structure of the building, so that the entire steel plate damping wall 1 can stably participate in the vibration system of the structure and effectively play the role of damping.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
