Description

Technical Field

[0001] This invention relates to the field of wind resistance and pressure reduction technology for prefabricated buildings, specifically to a wind resistance and pressure reduction device for prefabricated components. Background Technology

[0002] Prefabricated buildings are widely used in modern construction due to their short construction cycle, minimal on-site work, and high degree of component standardization. With the increasing use of prefabricated structures in high-rise and large-span buildings, the structural stability under dynamic loads such as strong winds and earthquakes has become a growing concern. Therefore, the engineering field typically introduces wind-resistant and pressure-reducing devices between prefabricated components to dissipate the vibration energy generated by the structure under dynamic loads, ensuring the overall safety of the structure.

[0003] However, most existing wind-resistant and pressure-reducing devices adopt a fixed structural design, and the damping parameters of the device are fixed after leaving the factory, making it impossible to adjust them on-site according to the wind load intensity and vibration characteristics of different regions. When the dynamic load conditions in the area where the device is located change or deviate from the design conditions, the fixed damping parameters will lead to a mismatch in the vibration load dissipation capacity, making it difficult for the device to meet the wind-resistant and pressure-reducing requirements in diverse engineering scenarios. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the damping parameters of existing wind-resistant and pressure-reducing devices are fixed and cannot be adjusted, and cannot be adapted to the wind load intensity and vibration characteristics of different regions. Therefore, this invention proposes a prefabricated wind-resistant and pressure-reducing device.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A prefabricated wind-resistant and pressure-reducing device includes: Two assembly side pillars are set parallel to each other and spaced apart; A deformation member is disposed between the two assembly side columns, and an adjustable damping component is provided on the deformation member; A support member, connected between the two assembly side columns and the deformation member, is used to transfer the vibration load borne by the assembly side columns to the deformation member, and the adjustable damping assembly dissipates the vibration load with matching damping strength.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the deformable component includes: There shall be at least two vertical beams, which shall be set parallel to each other and spaced apart. There are two diagonal braces, one end of which is rotatably connected to the surface of one of the vertical beams, and the other end is slidably connected to the surface of the other vertical beam.

[0008] Furthermore, the two diagonal braces are arranged in an alternating manner and connected to each other at their middle positions by pins; the surface of the vertical beam is provided with a slide rail, and the diagonal brace is provided with a slide rail that slides in cooperation with the slide rail; when the two vertical beams approach each other, the end of the diagonal brace slides along the slide rail on the surface of the vertical beam.

[0009] Furthermore, the adjustable damping assembly includes: The piston cylinder is fixedly installed on the surface of the vertical beam and is filled with damping fluid. A piston rod has a piston at one end and is slidably connected to the inside of the piston cylinder, and the other end extends through the piston cylinder to the outside. The end of the piston rod is connected to the end of the diagonal brace. The recovery chamber, which is connected to the piston cylinder, is used to contain the damping fluid that is squeezed out during the displacement of the piston rod.

[0010] Furthermore, the recovery chamber includes: The cylindrical body has an opening at one end; A cover is threadedly connected to the open end of the cylinder, and the cover is connected to the piston cylinder through a connecting pipe; A damping fluid flow barrier is clamped and fixed between the cylinder and the cover, and is used to adjust the flow cross-sectional area of ​​the damping fluid between the piston cylinder and the recovery chamber.

[0011] Furthermore, the damping fluid flow barrier is a circular plate with several flow holes on its surface, the diameter of which ranges from ~mm; the damping fluid flow barrier is replaceable to adjust the flow resistance encountered by the damping fluid flowing into the cylinder from the piston cylinder.

[0012] Furthermore, a base is fixedly mounted on the surface of the piston rod, and an elastic element is provided between the base and the surface of the piston cylinder, sleeved on the outside of the piston cylinder and the piston rod, with both ends of the elastic element abutting against the surfaces of the base and the piston cylinder, respectively.

[0013] Furthermore, the outer surface of the piston cylinder is provided with a threaded structure, and an adjusting seat is threadedly connected to the threaded structure. The end of the elastic element away from the base abuts against the adjusting seat, and the adjusting seat is adjustable along the axial position of the piston cylinder.

[0014] Furthermore, the support member includes: The first support is fixedly installed on the surface of the vertical beam, and each vertical beam is provided with no less than two first supports; The second support is provided on the surface of the assembly side column, and its number and distribution position are adapted to the first support; An adjusting rod is connected between the first support and the second support.

[0015] Furthermore, the adjusting rod includes: A threaded cylinder is fixedly installed on the outside of the first support; A high-strength threaded rod is threaded at one end into the threaded cylinder and at the other end into the second support. The screwing depth of the high-strength threaded rod is adjustable to accommodate different spacings between the two assembly side posts.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: The deformable component of this invention is disposed between two assembled side columns and equipped with an adjustable damping assembly. The adjustable damping assembly can flexibly adjust the damping strength on-site according to the wind load intensity, vibration characteristics, and deviation between the actual working conditions and the design conditions in different regions. This ensures that the damping parameters can be precisely matched with the actual dynamic load conditions, effectively avoiding the problem of mismatch in vibration load dissipation capacity caused by fixed damping parameters. The support component connects the assembled side columns and the deformable component, realizing the efficient transmission of the vibration load borne by the assembled side columns and concentrating the dispersed vibration load on the deformable component. It also ensures the stability and uniformity of load transmission, ensuring that the adjustable damping assembly can play its full role and efficiently dissipate vibration energy with an appropriate damping strength. This improves the structural stability of the prefabricated structure under dynamic loads such as strong winds and earthquakes, meets the wind resistance and pressure reduction requirements of high-rise and large-span prefabricated buildings in diverse engineering scenarios, further expands the application scope of prefabricated buildings, and ensures the overall safety and reliability of the structure.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides a prefabricated component wind-resistant and pressure-reducing device. The overall design is based on a modular concept, with clear division of labor and coordinated cooperation among the functional components to jointly construct a complete vibration load transfer and adjustable dissipation system. For example... Figures 1 to 4 As shown, the overall frame of the device is based on two parallel and spaced prefabricated side columns 1. These two side columns 1 serve as the interface between the device and the main building structure, responsible for receiving external wind loads and dynamic vibration loads from the building structure and channeling them into the internal functional components of the device for subsequent transmission and dissipation. In practical engineering applications, the prefabricated side columns 1 can be selected from various cross-sectional forms, such as steel profiles, square tubes, or rectangular steel columns, depending on the building structure, installation location, and stress requirements. Their surfaces are pre-drilled with connection nodes to cooperate with the supporting components 4, meeting the installation requirements of on-site assembly operations. The spacing between the two prefabricated side columns 1 can be flexibly selected according to the actual engineering scenario, providing sufficient deformation response space for the internal deformation components 2 while ensuring the overall rigidity of the device. It is worth noting that the prefabricated side columns 1 can not only be embedded into the building system as independent dedicated load-bearing components, but also be integrated with existing columns, shear wall edge components, etc., in the building structure, thereby further reducing the overall installation volume and engineering cost of the device.

[0021] Between the two assembly side columns 1, a deformable member 2 is provided, such as... Figure 1 and Figure 2As shown, an adjustable damping component 3 is installed on the deformable component 2. The deformable component 2 is the core intermediate component of this device for the transmission and conversion of vibration energy. Its structure itself can undergo controllable geometric deformation when subjected to lateral vibration loads, thereby driving the adjustable damping component 3 installed on it to dissipate energy through displacement output. Specifically, the deformable component 2 includes two basic components: vertical beams 21 and diagonal braces 22. There are no fewer than two vertical beams 21, which are arranged parallel to each other and spaced apart. As the longitudinal load-bearing skeleton of the deformable component 2, when subjected to lateral vibration loads transmitted from the support component 4, the diagonal braces 22 can be driven to produce corresponding motion responses by changing the distance between the two vertical beams 21. The vertical beams 21 can be made of various cross-sections such as I-beams, H-beams, or rectangular steel tubes. Their surfaces are machined to form functional connection interfaces with appropriate precision to meet various installation requirements such as the hinge nodes at the ends of the diagonal braces 22, the mounting base of the damping component 3, and the connection nodes of the support component 4. Regarding the selection of the number of vertical beams 21, depending on the overall stress state of the device and the needs of the installation conditions, a basic configuration of two vertical beams 21 can be adopted, or a multi-layer parallel structure can be formed by adding one vertical beam 21 on each side to adapt to engineering scenarios with larger spans or higher load strengths.

[0022] There are two diagonal braces 22. One end of each diagonal brace 22 is rotatably connected to the surface of one of the vertical beams 21, and the other end is slidably connected to the surface of the other vertical beam 21. The two diagonal braces 22 are arranged diagonally between the two vertical beams 21. One end of each brace is rotatably connected to the vertical beam 21 via a hinge pin. This hinge structure allows the diagonal brace 22 to rotate freely around the hinge center to adapt to the dynamic adjustment of the inclination angle of the diagonal brace 22 when the distance between the two vertical beams 21 changes. The other end is in contact with the surface of the other vertical beam 21 via a sliding mechanism and can slide directionally along this surface. The two diagonal braces 22 are staggered and connected to each other at the middle position by a pin 23. The two diagonal braces 22 are arranged in an "X" shape in space. The pin 23 at the intersection point binds the two braces 22 into a whole at the middle position, so that the two diagonal braces 22 respond and deform together under load, effectively preventing structural deflection caused by uneven force on a single diagonal brace 22. The pin 23 provides central constraint and also serves as a hinge point for the relative rotation between the two diagonal braces 22, further ensuring the motion coordination and structural stability of the deformable component 2 throughout the deformation process. The pin 23 can be a high-strength pin, used in conjunction with a cotter pin or elastic retaining ring for axial locking to prevent loosening under long-term vibration loads.

[0023] To ensure the directional and stable sliding of the end of the diagonal brace 22 on the surface of the vertical beam 21, a slide rail is provided on the surface of the vertical beam 21. A slide rail is installed on the diagonal brace 22 to slide smoothly within the slide rail. The slide rail is embedded in the slide rail and can slide freely back and forth along the length of the slide rail. The structure of the slide rail can be selected according to actual working conditions, such as a dovetail groove, T-groove, or rectangular guide groove. Its inner wall is precision machined to reduce sliding friction resistance. A wear-resistant coating or a guide bushing can be installed on the inner wall of the slide rail to improve sliding accuracy and durability during long-term use. The installation position of the slide rail at the end of the diagonal brace 22 is precisely matched with the cross-sectional profile of the slide rail to ensure that the end of the diagonal brace 22 does not experience out-of-plane displacement during sliding, thereby maintaining the in-plane motion constraint of the entire deformable component 2. When the two vertical beams 21 approach each other, the ends of the diagonal braces 22 slide along the tracks on the surfaces of the vertical beams 21. Driven by the decreasing distance between the two vertical beams 21, the sliding ends of the "X"-shaped diagonal braces 22 generate relative displacement along the tracks, and the tilt angle of the entire diagonal brace 22 increases accordingly. The deformation member 2 thus completes the geometric transformation process from external vibration load input to internal motion output, providing driving displacement for the adjustable damping assembly 3. Correspondingly, when the two vertical beams 21 separate from each other under the reset drive of the elastic member 6, the ends of the diagonal braces 22 slide in the opposite direction along the tracks, and the entire device returns to its initial geometric state, preparing the structure for the next vibration load, thereby achieving a continuous dissipative response to reciprocating vibration loads.

[0024] Based on the motion drive provided by the deformable component 2, the adjustable damping component 3 undertakes the final dissipation function of vibration energy, and at the same time has the ability to adjust the damping parameters on-site according to different engineering scenarios. This is the core technical feature that distinguishes this invention from existing fixed wind-resistant and pressure-reducing devices. Figure 1 and Figure 3 As shown, the adjustable damping assembly 3 includes three core components: piston cylinder 31, piston rod 32, and recovery chamber 33. The three components work together to form a complete hydraulic damping dissipation circuit.

[0025] The piston cylinder 31 is fixedly installed on the surface of the vertical beam 21 and is filled with damping fluid. As the main pressure vessel of the adjustable damping assembly 3, the piston cylinder 31's axial direction is matched with the direction of the movement displacement at the end of the inclined brace 22, ensuring that the linear displacement at the end of the inclined brace 22 can be efficiently converted into the axial compression displacement of the piston rod 32. The piston cylinder 31 can be precision-machined from seamless steel pipe, with its inner wall roundness and roughness strictly controlled to ensure the sealing quality between the piston and the inner wall. The damping fluid filled in the piston cylinder 31 can be selected from various media such as silicon-based damping fluid, mineral oil-based damping fluid, or magnetorheological fluid of different viscosity grades according to engineering requirements. The viscosity characteristics of the damping fluid are one of the fundamental parameters affecting the magnitude of hydraulic resistance, and can work synergistically with the orifice configuration of the damping fluid flow obstruction component 334 (described later) to achieve composite adjustment of the overall damping characteristics. The piston cylinder 31 can be fixed to the surface of the vertical beam 21 by welding or bolt flange connection. The fixing point should be calculated to ensure the installation stability of the piston cylinder 31 under high-frequency reciprocating load.

[0026] One end of the piston rod 32 is fitted with a piston and slidably connected inside the piston cylinder 31, while the other end extends through the piston cylinder 31 to the outside. The end of the piston rod 32 is connected to the end of the diagonal brace 22. The connection between the piston rod 32 and the end of the diagonal brace 22 can be achieved through various methods such as hinged connection, threaded connection, or pin fixing to adapt to different assembly conditions. Among these, the hinged connection method has superior adaptability in engineering applications because it can compensate for slight angular deviations between the movement direction of the diagonal brace 22 and the axial direction of the piston rod 32. A sealing ring is provided at the piston end to form a tight hydraulic seal with the inner wall of the piston cylinder 31. A shaft seal structure is also provided at the end cap where the piston rod 32 penetrates the piston cylinder 31 to prevent damping fluid from leaking outwards along the rod surface. When the end of the diagonal brace 22 is displaced by the change in the spacing of the vertical beam 21, the piston rod 32 connected to it then undergoes axial pressing motion in the piston cylinder 31. The piston applies a compressive force to the damping fluid at its front end, driving the damping fluid to flow into the recovery chamber 33 through the connecting pipe 333. When the damping fluid flows through the flow hole of the damping fluid flow barrier 334, it is subjected to throttling resistance and generates frictional heat. The vibration energy is thus effectively dissipated in the form of heat energy.

[0027] The recovery chamber 33 is connected to the piston cylinder 31 and is used to accommodate the damping fluid squeezed out during the displacement of the piston rod 32. The recovery chamber 33 provides a buffer and storage space for the flow of damping fluid between the piston cylinder 31 and the external cavity. Through its internal replaceable damping fluid flow barrier 334, the flow resistance of the damping fluid can be adjusted and controlled on-site. This structural design is key to realizing the adjustable damping function of this device. Figure 1 and Figure 3As shown, the recovery chamber 33 comprises three components: a cylinder 331, a cover 332, and a damping fluid flow barrier 334. One end of the cylinder 331 is open, serving as the installation inlet for the damping fluid flow barrier 334, and cooperates with the cover 332 to achieve closure. The other end of the cylinder 331 is a closed bottom surface, forming a fluid storage chamber of a certain volume inside the cylinder 331. This provides temporary storage space for the damping fluid pushed out by the piston, preventing abnormal back pressure from occurring in the hydraulic circuit due to insufficient damping fluid.

[0028] The cover 332 is threaded to the open end of the cylinder 331, and is connected to the piston cylinder 31 via a connecting pipe 333. The threaded connection between the cover 332 and the cylinder 331 facilitates on-site disassembly and assembly. Operators only need to rotate the cover 332 to open or close the recovery chamber 33, enabling quick removal and replacement of the damping fluid flow barrier 334 without disassembling other components of the damping assembly 3, making maintenance simple and efficient. The connecting pipe 333 connects the cover 332 and the piston cylinder 31 in the fluid channel. Its installation position is on the pressurized side of the damping fluid inside the piston cylinder 31. Driven by piston pressure, the damping fluid flows through the connecting pipe 333 to the recovery chamber 33. The diameter of the connecting pipe 333 can be selected according to the designed damping fluid flow rate range. The pipe diameter affects the overall flow resistance reference value of the hydraulic circuit, and together with the damping fluid flow barrier 334, determines the final dissipation resistance characteristics.

[0029] The damping fluid flow barrier 334 is clamped and fixed between the cylinder 331 and the cover 332, and is used to adjust the flow cross-sectional area of ​​the damping fluid between the piston cylinder 31 and the recovery chamber 33. Figure 4 As shown, the damping fluid flow barrier 334 is pressed against the open end face of the cylinder 331 by the inner end face of the cover 332, forming a stable and reliable clamping and fixing relationship. When the cover 332 is tightened, the damping fluid flow barrier 334 is firmly confined between the two and will not undergo axial displacement or fall off under the action of damping fluid impact pressure. When the cover 332 is unscrewed, the damping fluid flow barrier 334 can be easily removed and replaced with a specification with a different flow cross-sectional area, thereby changing the throttling resistance encountered by the damping fluid when flowing between the piston cylinder 31 and the recovery chamber 33, and realizing the precise on-site configuration of adjustable damping strength.

[0030] Furthermore, the damping fluid flow barrier 334 is a circular plate with several flow holes on its surface, the diameter of which ranges from 10 to 50 mm. The damping fluid flow barrier 334 is replaceable to adjust the flow resistance encountered by the damping fluid flowing into the cylinder 331 from the piston cylinder 31. The outer diameter of the circular plate is precisely matched with the inner diameter of the opening end of the cylinder 331, ensuring accurate circumferential positioning. No additional guiding mechanism is required during installation, allowing for quick alignment and installation. The flow holes can be arranged in a uniform distribution pattern on the surface of the circular plate. The combination of hole size and number of holes determines the total effective flow cross-sectional area of ​​the damping fluid, and the ratio between the two can be specifically designed according to the required damping force for each engineering scenario. By pre-preparing a series of damping fluid flow barrier 334s with different hole diameters and numbers, engineers can select damping fluid flow barrier 334s with suitable flow cross-sectional areas on-site based on local wind load measurement data and relevant design specifications, so as to accurately match the damping characteristics of the device with the actual local dynamic load environment. It should be further explained that, in addition to the above-mentioned circular single-layer perforated plate form, the damping fluid flow barrier 334 can also adopt a multi-layer stacked perforated plate structure. By changing the number of stacked layers, the total flow cross-sectional area can be continuously adjusted, thereby expanding the damping adjustment range. Alternatively, a grid-shaped porous throttling plate can be used, which utilizes the grid channels to form a uniformly distributed throttling resistance for the damping fluid, improving the uniformity of hydraulic resistance distribution and reducing the risk of local erosion. All of the above forms are equivalent alternatives to the damping fluid flow barrier 334 of this invention, and the specific selection can be determined according to the actual engineering needs.

[0031] Regarding the elastic reset mechanism, to ensure that the adjustable damping assembly 3 can reset promptly after the vibration load is reduced and to continuously and stably output damping dissipation response under reciprocating vibration conditions, a base 5 is fixedly installed on the surface of the piston rod 32. An elastic element 6 is provided between the base 5 and the surface of the piston cylinder 31, sleeved on the outside of the piston cylinder 31 and the piston rod 32. The two ends of the elastic element 6 abut against the surfaces of the base 5 and the piston cylinder 31, respectively. The base 5 is fixedly installed at an appropriate position on the exposed section of the piston rod 32 and can be integrated with the piston rod 32 by welding or flange clamping. The outer diameter of the base 5 is larger than the outer diameter of the piston cylinder 31 to provide a stable abutment surface for the elastic element 6. When the piston rod 32 is pressed into the piston cylinder 31 under the drive of the diagonal brace 22, the base 5 moves synchronously towards the end face of the piston cylinder 31 along with the piston rod 32. The elastic element 6 is axially compressed between the end face of the base 5 and the end face of the piston cylinder 31, and the elastic potential energy is stored synchronously as the compression increases. When the external vibration load weakens or disappears, the elastic element 6 releases the elastic potential energy, pushing the base 5 to drive the piston rod 32 to reset outward, thereby driving the diagonal brace 22 and the deformation member 2 to restore their initial geometric state. The elastic element 6 is sleeved on the outside of the piston cylinder 31 and the piston rod 32, making full use of the outer circumferential space of the piston cylinder 31. The structure is compact and does not occupy additional installation space. The elastic element 6 can take various forms, such as helical compression springs, disc spring assemblies, or rubber elastomers. Helical compression springs are suitable for general vibration frequency conditions due to their linear stiffness characteristics and good fatigue life. Disc spring assemblies have the characteristics of high stiffness and small deformation, making them suitable for situations with large loads and limited installation space. Furthermore, the elastic stiffness can be flexibly changed by adjusting the number of overlapping discs, thus achieving coarse adjustment of the magnitude of the reset force. Rubber elastomers have both damping and elastic characteristics, and can simultaneously undertake the function of auxiliary damping in some special working conditions, further enriching the energy dissipation means of the device.

[0032] Furthermore, to achieve precise on-site adjustment of the elastic restoring force of the elastic element 6, a threaded structure is provided on the outer surface of the piston cylinder 31. An adjusting seat 7 is threadedly connected to the threaded structure. The end of the elastic element 6 away from the base 5 abuts against the adjusting seat 7, and the adjusting seat 7 is adjustable along the axial direction of the piston cylinder 31. The adjusting seat 7 engages with the threaded structure on the outer surface of the piston cylinder 31 through its threads. By rotating the adjusting seat 7, the operator can make it move precisely and controllably along the axial direction of the piston cylinder 31, thereby changing the installation pre-compression of the elastic element 6 and thus adjusting the magnitude of the elastic restoring force applied by the elastic element 6 to the piston rod 32. The adjustment of the elastic restoring force has a direct impact on the dynamic response characteristics of the device under different vibration frequencies and amplitudes: a larger pre-compression can improve the reset sensitivity and response speed of the device under high-frequency, small-amplitude conditions; a smaller pre-compression is beneficial for reducing the reset resistance of the device under low-frequency, large-amplitude conditions, allowing the diagonal brace 22 to respond more fully to deformation displacement and ensuring sufficient flow and dissipation of the damping fluid. After adjustment, the adjusting seat 7 can be axially locked by using a locking nut or an anti-loosening thread to prevent accidental axial movement under long-term vibration loads and ensure the long-term stability of the elastic parameter settings. The elastic element 6 and the hydraulic damping mechanism of the adjustable damping assembly 3 together constitute a spring-damping coupling system. The parameters of both can be adjusted independently by replacing the damping fluid flow blocking component 334 and adjusting the axial position of the adjusting seat 7, realizing the decoupled control of elastic stiffness and damping strength, enabling the device to perform fine parameter configuration for dynamic load characteristics in different regions.

[0033] In terms of load transfer channel construction, support member 4 connects the two assembly side columns 1 and deformation member 2, and is used to transfer the vibration load borne by the assembly side columns 1 to the deformation member 2, and finally dissipation is completed by the adjustable damping component 3 with matching damping strength. As a structural bridge between the external load input end and the internal dissipation mechanism, the stiffness, connection method and length adjustability of support member 4 have a direct impact on the force transfer efficiency and installation adaptability of the entire device. Specifically, support member 4 includes three components: first support 41, second support 42 and adjusting rod 43. The first support 41 is fixedly installed on the surface of the vertical beam 21, and each vertical beam 21 is provided with no less than two first supports 41; the second support 42 is provided on the surface of the assembly side column 1, and its number and distribution position are adapted to the first support 41. The first support 41 and the second support 42 serve as connection nodes on the deformable member 2 side and the assembly column 1 side, respectively. They can be installed by welding or high-strength bolts. The structural form can be a lug support, flange support, or box support to meet the installation interface requirements of the adjusting rod 43 end. The provision of at least two first supports 41 on each vertical beam 21 ensures a multi-point constraint relationship between the deformable member 2 and the supporting member 4, effectively preventing out-of-plane instability of the deformable member 2 under vibration loads. In specific engineering applications, three or more first supports 41 can be evenly arranged on each vertical beam 21 to further distribute the load transfer points and increase the redundancy of the structural connections.

[0034] The adjusting rod 43 connects the first support 41 and the second support 42. As the core force-transmitting rod of the support component 4, its axial stiffness directly affects the transmission rate and integrity of the vibration load. Further, the adjusting rod 43 includes a threaded cylinder 431 and a high-strength threaded rod 432. The threaded cylinder 431 is fixedly installed on the outside of the first support 41, and its inner wall is machined with internal threads that mate with the high-strength threaded rod 432. Its outer end is fixed to the first support 41 by welding or flange connection, forming a stable and reliable installation foundation. One end of the high-strength threaded rod 432 is threaded into the threaded cylinder 431, and the other end is connected to the second support 42. The screw depth of the high-strength threaded rod 432 is adjustable to accommodate different spacings between the two assembly side columns 1. The high-strength threaded rod 432 is made of high-strength structural steel, and its cross-sectional dimensions and thread specifications have been verified by load-bearing capacity calculations to ensure sufficient axial force transmission capacity and fatigue resistance. By rotating the high-strength threaded rod 432, its depth of insertion into the threaded cylinder 431 can be continuously adjusted, thereby changing the effective working length of the adjusting rod 43. This allows the support component 4 to flexibly adapt to installation conditions with different spacings of the assembly side columns 1, eliminating the need to prepare special components for different spacings and significantly improving the engineering versatility and installation flexibility of the device. After adjustment, the high-strength threaded rod 432 can be reliably axially locked by configuring double nuts or wedge-shaped anti-loosening plates to prevent automatic loosening under long-term vibration loads, ensuring the long-term stability and connection reliability of the load transmission channel of the support component 4.

[0035] In terms of overall assembly, this device adheres to a fully prefabricated installation concept. All functional components are interconnected via detachable connections, requiring no hot work during on-site installation. This minimizes interference with the main building structure and facilitates its application in the renovation and reinforcement of existing buildings. The parameter adjustments for each functional module are independent and do not interfere with each other: replacing the damping fluid flow barrier 334 to adjust the flow cross-sectional area, rotating the adjusting seat 7 to change the elastic pre-compression, and rotating the high-strength threaded rod 432 to readjust the side column spacing—all three adjustments can be completed independently without disassembling the entire device, making maintenance convenient and efficient. In terms of material selection, low-alloy high-strength structural steel should be selected for the main load-bearing components such as the side column 1, vertical beam 21, and diagonal brace 22 to meet the strength and fatigue life requirements under dynamic load conditions; medium-carbon alloy steel with quenching and tempering treatment should be selected for piston cylinder 31 and piston rod 32 to balance strength and machining accuracy; if the elastic component 6 adopts the form of a helical spring, spring steel should be selected and strengthened by heat treatment to ensure elastic stability under long-term reciprocating load conditions; the damping fluid flow barrier component 334 can be made of stainless steel or aluminum alloy to balance corrosion resistance and lightweight requirements, and facilitate manual replacement on site.

[0036] Based on the structural design of the above functional modules, the prefabricated component wind-resistant and pressure-reducing device proposed in this invention directs the vibration load of the assembled side column 1 to the deformation component 2 through the support component 4. The geometric deformation of the deformation component 2 converts the vibration displacement into the piston movement of the adjustable damping component 3. Then, the vibration energy is finally dissipated through the controlled throttling flow of the damping fluid. At the same time, with the help of the replaceable damping fluid flow barrier 334 and the axially adjustable adjustment seat 7, the damping strength and elastic recovery force can be independently controlled on site. This forms a complete functional link from load transfer, deformation conversion, energy dissipation to parameter control, effectively solving the technical problems of the existing fixed wind-resistant and pressure-reducing devices having unadjustable damping parameters and being difficult to adapt to the dynamic load requirements of diverse engineering scenarios.
