[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, instead of all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0031] The present application will be further described below with reference to the drawings and specific embodiments, but not as a limitation of the present application.

[0032] The damper-based building wall anti-seismic structure provided in the present application, with reference to Figures 1-6 , comprises:

[0033] ​Two pre-embedded components 1 are fixedly arranged on the upper wall body 3 and the lower wall body 4 respectively; each pre-embedded component 1 is provided with a pre-embedded pipe sleeve 11, the pre-embedded pipe sleeve 11 penetrates into the wall body and is firmly combined with the wall body structure to ensure the connection strength and stability; and

[0034] A damping component 2 includes a hollow support 21, a friction damper 22, a sliding plate 23, and a socket shaft 24, the friction damper 22 is fixedly arranged in the middle of the hollow support 21, the sliding plate 23 is slidably connected to the hollow support 21 through an elastic member 25, and the socket shaft 24 is arranged on the sliding plate 23 for clamping in the pre-embedded pipe sleeve 11 of the corresponding pre-embedded component 1.

[0035] In this embodiment, the design of the pre-embedded component 1 aims to ensure the stable connection of the friction damper 22 with the main structure of the building. The pre-embedded pipe sleeve 11 is designed to match the size of the socket shaft 24 to ensure that the socket shaft 24 can be accurately and firmly clamped inside the pre-embedded pipe sleeve 11, forming a stable connection. The hollow support 21 provides a space for the friction damper 22 and the sliding plate 23, while protecting the internal components from the external environment. The friction damper 22 is fixedly arranged to dissipate energy through friction when the wall is subjected to vibration or external force, effectively reducing the vibration amplitude of the wall and improving the seismic performance of the building. The elastic member 25 (such as a spring or elastic pad) is slidably connected in the hollow support 21, and its movement is driven by the vibration generated when the external force acts on the sliding plate 23. The socket shaft 24 is used to form a clamping connection with the pre-embedded pipe sleeve 11 on the pre-embedded component 1, and the size of the socket shaft 24 is designed to match the pre-embedded pipe sleeve 11, ensuring the firmness of the connection between the damping component 2 and the pre-embedded component 1. The elastic member 25, such as a spring or elastic pad, is connected to the sliding plate 23 at one end and fixed to the inner wall of the friction damper 22 or the hollow support 21 at the other end. The elastic member 25 provides the necessary restoring force when the sliding plate 23 moves, ensuring that the socket shaft 24 can be stably clamped inside the pre-embedded pipe sleeve 11, while quickly returning to the initial position after the vibration stops, ensuring the stability of the structure. The damping-based seismic structure of the building wall provided by the present application first needs to ensure the accurate position and fixing strength of the pre-embedded component 1 during installation, and then realizes the rapid and stable connection of the damping component 2 and the wall through the accurate clamping of the socket shaft 24 and the pre-embedded pipe sleeve 11. In terms of maintenance, due to the use of a socketable mechanical connection node, the replacement and maintenance of the damper become simpler, without the need to damage the wall, reducing maintenance costs and construction difficulty.

[0036] In this embodiment, reference is made to Figures 1-5, the elastic member 25 is a spring, which is arranged in the hollow support 21, and one end of the spring is connected with the sliding plate 23, and the other end is fixed on the outer surface of the friction damper 22, to provide the elastic force required for the sliding of the socket shaft 24. When the building is subjected to external forces such as earthquakes, the vibration of the wall will be transmitted to the friction damper 22. At this time, the friction damper 22 dissipates a part of the energy through the internal friction element, and at the same time, converts another part of the energy into the movement of the sliding plate 23, i.e. the compression or stretching of the spring. This process realizes the conversion of energy from mechanical vibration to elastic deformation. After the spring is compressed or stretched, it will generate a reverse restoring force according to its elastic coefficient, which ensures that the sliding plate 23 can quickly recover to the initial position after the vibration stops, thereby driving the socket shaft 24 to smoothly reset from the embedded pipe sleeve 11, maintaining the integrity and stability of the structure. The elastic force of the spring can also adjust the movement speed of the sliding plate 23, to avoid the movement of the sliding plate 23 being too fast during strong vibration, thereby reducing the impact force inside the structure and improving the dynamic stability of the overall structure. The spring material is selected to be a material with high strength and high elasticity, to ensure the performance stability and durability of the spring in long-term use. According to the seismic grade of the building, the friction coefficient of the damper and other factors, the elastic coefficient of the spring is optimized to ensure the response speed and energy conversion efficiency of the spring under different external forces. In the building wall seismic structure based on the damper in the application, the ingenious design and application of the elastic member 25 (spring) not only enhances the seismic performance of the structure, but also improves the recovery ability of the structure after being subjected to external forces, ensuring the safety of the building in earthquakes and other natural disasters.

[0037] Specifically, referring to Figures 4-5The hollow support 21 is provided with a sliding groove 20 to prevent the sliding plate 23 from slipping off, and the sliding plate 23 is provided with a sliding block connected to the sliding groove 20. The sliding groove 20 provides a precise movement path for the sliding plate 23, ensuring that the sliding plate 23 can slide stably in the predetermined direction when subjected to force, avoiding structural instability caused by inconsistent sliding direction. The limiting design of the sliding groove 20 can effectively prevent the sliding plate 23 from excessive sliding under strong vibration or external force, avoiding the sliding plate 23 from slipping out of the shell, thereby ensuring the integrity and safety of the structure. The sliding contact surface between the sliding block and the sliding groove 20 reduces the direct friction between the sliding plate 23 and the hollow support 21, reduces the movement resistance, and makes the movement of the sliding plate 23 more smooth. The installation of the sliding block ensures the stable sliding of the sliding plate 23 in the sliding groove 20, avoiding shaking or deviation during sliding, improving the accuracy of the movement of the sliding plate 23 and the overall stability of the structure. By reducing unnecessary friction loss, the design of the sliding block improves the energy conversion efficiency from vibration to the movement of the sliding plate 23, thereby enhancing the energy dissipation capacity of the friction damper 22. Therefore, the combination design of the sliding groove 20 and the sliding block of the present application not only improves the seismic performance of the building wall seismic structure based on the damper, but also optimizes the energy conversion efficiency and reduces the maintenance cost. The specific performance is: by limiting the sliding range of the sliding plate 23, the damage of the structure under strong external force is avoided, and the safety of the building in natural disasters such as earthquakes is improved; the low-friction design of the sliding block and the sliding groove 20 reduces the wear of the structure, prolongs the service life of the structure, and reduces the maintenance frequency and cost; the optimized sliding path and reduced friction loss improve the energy dissipation efficiency of the friction damper 22, and enhance the overall seismic performance of the structure.

[0038] In this embodiment, the two ends of the socket shaft 24 are provided with anti-disengagement structures to prevent the socket shaft 24 from disengaging from the embedded pipe sleeve 11 when the wall body is subjected to strong vibration. The anti-disengagement structure increases the contact area or friction coefficient between the socket shaft 24 and the embedded pipe sleeve 11, thereby increasing the friction between the two, which can effectively resist the axial pulling force and prevent the socket shaft 24 from disengaging from the embedded pipe sleeve 11 when the wall body is subjected to strong vibration. In addition, the anti-disengagement structure can use the principle of mechanical locking, for example, a lock ring or a locking pin that can expand is designed, when the socket shaft 24 is inserted into the embedded pipe sleeve 11 and reaches a predetermined depth, the locking structure is automatically activated to form a mechanical lock, further enhancing the stability of the connection. In addition, an expandable ring structure is designed at both ends of the socket shaft 24, when the socket shaft 24 is inserted into the embedded pipe sleeve 11, the locking ring expands under the action of a spring or hydraulic pressure, tightly contacting the inner wall of the embedded pipe sleeve 11, forming a mechanical lock. In addition, a retractable locking pin is designed on the socket shaft 24, when the socket shaft 24 reaches a predetermined position in the embedded pipe sleeve 11, the locking pin extends under the action of mechanical or electromagnetic force, and is clamped into the pre-designed hole position in the inner wall of the embedded pipe sleeve 11, forming a stable locking state. A special texture or coating is designed on the contact surface of the socket shaft 24 and the embedded pipe sleeve 11, which can also increase the friction coefficient to improve the stability of the connection and prevent axial sliding under strong vibration. The anti-disengagement structure of the socket shaft 24 of the present application not only significantly improves the seismic performance of the damper-based building wall seismic structure, but also brings other multiple benefits, such as: under the action of strong earthquakes, the anti-disengagement structure can effectively prevent the disengagement between the socket shaft 24 and the embedded pipe sleeve 11, avoiding the instability and collapse of the structure, protecting the safety of buildings and personnel. Because the anti-disengagement structure enhances the stability of the connection, reduces the maintenance requirements of the structure during use, and reduces the maintenance cost and difficulty. The flexibility of the anti-disengagement structure design makes it suitable for different levels of earthquakes and various external forces, improving the adaptability and versatility of the structure.

[0039] In particular, with reference to Figure 2 and Figure 6, the embedded pipe sleeve 11 is integrally formed with the embedded component 1, ensuring the structural tightness and high-precision matching of the geometric dimensions of the two, and the inner diameter of the embedded pipe sleeve 11 matches the outer diameter of the socket shaft 24, ensuring that the two can form a tight fit when connected, thereby improving the stability and carrying capacity of the connection. The integrally formed design ensures the structural continuity and dimensional accuracy between the embedded pipe sleeve 11 and the embedded component 1, avoiding structural instability and loose connections due to assembly errors, improving the overall stability and seismic performance of the structure. And the integrally formed embedded component 1 simplifies the installation and alignment steps during construction, reduces on-site construction errors, reduces construction difficulty, and speeds up construction progress. In addition, due to the integrally formed design, the assembly and adjustment work on site is reduced, reducing construction costs, and at the same time, precise size matching reduces material waste, improving overall cost efficiency. Further, the integrated embedded pipe sleeve 11 and embedded component 1 are easier to inspect and replace during maintenance, reducing maintenance costs and extending the service life of the structure. In actual construction, the integrally formed design of the embedded pipe sleeve 11 and the embedded component 1 needs to strictly control the following points: the embedded component 1 and the embedded pipe sleeve 11 should be made of high-strength and high-durability materials to ensure the stability and safety of the structure during long-term use; the fit gap between the inner diameter of the embedded pipe sleeve 11 and the outer diameter of the socket shaft 24 should be strictly controlled to ensure the tightness and stability of the connection; during construction, strict accordance with the design drawings and construction specifications should be followed to ensure the accurate position and direction of the embedded component 1, avoiding construction errors. The integrally formed design of the embedded pipe sleeve 11 and the embedded component 1 is an important innovation point in the damper-based building wall seismic structure of the present application, which improves the accuracy and stability of the structure connection, simplifies the construction process, reduces construction costs, and significantly enhances the seismic performance and structural safety of the building.

[0040] In the present embodiment, the embedded component 1 is made of high-strength concrete or steel. The high compressive strength of high-strength concrete ensures that the embedded component 1 can withstand the large load of the wall under the action of external forces such as earthquakes, improving the carrying capacity and stability of the structure; steel has high strength and low density, which means that under the same carrying capacity, the volume and weight of the steel embedded component 1 are smaller, facilitating construction and installation, and the ductility and toughness of steel allow it to deform greatly without breaking when subjected to dynamic loads such as earthquakes, improving the seismic performance and safety of the structure.

[0041] The two ends of the sliding plate 23 are designed to extend out of the hollow support 21, forming a direct operation interface, so that the construction personnel can directly operate the exposed part of the sliding plate 23, the sliding plate 23 is connected with the spring, by directly pushing or pulling the exposed part of the sliding plate 23, the spring can be compressed, so that the sliding plate 23 moves inward along the internal track of the hollow support 21; when the hole position is aligned, the external pushing force or pulling force disappears, the restoring force of the spring will automatically reset the sliding plate 23, realizing that the socket shaft 24 on the sliding plate 23 is clamped into the embedded sleeve.

[0042] The application provides a construction method of a damper-based building wall body anti-seismic structure.

[0043] Step one, pre-burying stage: in the early stage of wall body construction, the pre-burying part with embedded sleeve is accurately bound and arranged, the clamping groove size of the embedded sleeve needs to strictly match the socket shaft 24, so as to ensure the close connection between the two; during the concealed acceptance, the size, position and levelness of the pre-burying part are strictly detected by using precise measuring tools, so as to ensure that the connection and reinforcement of the pre-burying part with the upper wall body 3 and the lower wall body 4 is stable, and the displacement of the pre-burying part caused by the concrete pressure in the pouring process is avoided, so as to affect the stability and safety of the structure;

[0045] Step three, installation stage: the socket shaft 24 in the damper component 2 is aligned with the embedded sleeve 11 in the pre-burying component 1, so as to ensure the accurate alignment between the two, which is a key step to realize the stability and anti-seismic performance of the structure; the exposed part of the sliding plate 23 is pushed or pulled to compress the spring, so that the sliding plate 23 moves inward along the internal track of the hollow support 21, and the socket shaft 24 is aligned with the inside of the embedded sleeve 11 of the corresponding pre-burying component 1; this process needs to be carried out smoothly and slowly, then the sliding plate 23 is loosened, so as to ensure that the socket shaft 24 is completely and correctly inserted into the embedded sleeve 11; after the socket shaft 24 is completely inserted into the embedded sleeve 11, the pushing is stopped, and professional tools are used to detect the levelness and fastening degree of the friction damper 22 component, so as to ensure the stability and safety of the structure;

[0046] Step four, acceptance stage: whether the levelness of the friction damper 22 product after installation meets the requirements is detected, and after the inspection is qualified, the damper component 2 is wrapped tightly by using protective materials, so as to avoid pollution and damage caused by subsequent construction.

[0047] The construction method of the damper-based building wall anti-seismic structure provided by the application ensures the stability and anti-seismic performance of the structure through detailed steps and strict construction standards, and provides safer and more efficient anti-seismic protection for the building. From the accurate setting in the pre-burying stage to the fine operation in the installation stage and the strict detection in the acceptance stage, each step reflects the high attention to the structural safety and construction quality. Through this construction method, the application provides strong technical support for the building safety in earthquake-prone areas, and ensures the stability of the building and the safety of the personnel in natural disasters such as earthquakes.

[0048] The above are only the preferred embodiments of the present application, and do not limit the implementation and protection scope of the present application.
