Abstract

This invention belongs to the field of structural engineering and structural vibration reduction technology, and relates to an open-type arrangement device and frame for a self-resetting damper. The self-resetting damper of this invention, as a core energy-dissipating component, can dissipate seismic energy through its own deformation under seismic loading, effectively reducing energy accumulation in the structure during earthquakes and minimizing structural damage.

Description

Technical Field

[0001] This invention belongs to the field of structural engineering and structural vibration reduction technology, and relates to an open-type arrangement device and frame for a self-resetting damper. Background Technology

[0002] Traditional earthquake-resistant design principles allow structures to dissipate energy during earthquakes through the plastic deformation of major structural members. While this can prevent structural collapse and casualties, it often results in significant residual deformation and damage. Post-disaster structures may be forced to demolish due to excessive repair costs or functional loss, leading to severe resource waste and disruption of social operations.

[0003] Currently, recoverable functional structures have become a research hotspot in the field of structural earthquake resistance and disaster reduction due to their superior post-earthquake functional recovery capabilities. Arranging self-resetting components in a structure can significantly reduce post-earthquake residual deformation, achieving the goal of minimal residual deformation and rapid commissioning. Self-resetting components typically consist of energy-dissipating components, resetting components, and force-transmitting components. When installed in traditional frame structures, structural damage is concentrated in the self-resetting components, effectively protecting the main structure and controlling post-earthquake residual deformation.

[0004] However, in its progress towards large-scale engineering applications, self-resetting technology still faces challenges such as complex construction, high cost, and poor reliability and durability, and some key bottlenecks urgently need to be overcome. Currently, self-resetting components mostly adopt traditional herringbone, K-shaped, diagonal, and lasso-shaped arrangements, which have the following shortcomings: First, the relative displacement between the two ends of the self-resetting component is limited; second, the restoring force in the self-resetting component limits its energy dissipation performance under small displacement conditions; and third, traditional arrangements occupy a large amount of building space, potentially limiting or even sacrificing some building functions. Summary of the Invention

[0005] The purpose of this invention is to provide an open-type arrangement device and frame for a self-resetting damper, in order to solve the technical problems of limited relative displacement at both ends of the self-resetting member, the reset force in the self-resetting member limiting the energy dissipation performance of the member under small displacement conditions, and the large building space occupied by the traditional arrangement of self-resetting members.

[0006] To achieve the above objectives, the present invention employs the following technical solution:

[0007] This invention discloses an open arrangement device for a self-resetting damper, comprising:

[0008] Right-angle curved rod;

[0009] A self-resetting damper, one end of which is rotatably connected to the right-angled curved rod;

[0019] Furthermore, the inner cylinder connecting section includes a first connecting plate, a second connecting plate, and a connecting cylinder. The first connecting plate is fixedly connected to the second connecting plate through the connecting cylinder. The force transmission screw passes through the first connecting plate, the second connecting plate, and the connecting cylinder. The first connecting plate is fixedly connected to the inner cylinder. Several sets of U-shaped energy-dissipating plates are symmetrically arranged on both sides of the connecting cylinder. The connecting cylinder is fixedly connected to the outer cylinder through several sets of U-shaped energy-dissipating plates.

[0020] The inner cylinder is provided with an inner cylinder lug plate, and the inner cylinder lug plate is rotatably connected to the second lug plate;

[0021] The outer cylinder bottom plate is provided with an outer cylinder ear plate, which is rotatably connected to the right-angle curved rod.

[0022] Furthermore, a first stiffening rib is provided between the first connecting plate and the connecting cylinder, and a first stiffening rib is provided between the second connecting plate and the connecting cylinder.

[0023] Furthermore, each group consists of two U-shaped energy-consuming panels, which are arranged opposite to each other.

[0024] Furthermore, the limiting component is a nut, and the nut is connected to the force transmission screw via a thread.

[0026] The distance from the connection point of the self-resetting damper and the right-angled crank to the connection point of the first ear plate and the right-angled crank is greater than the distance from the connection point of the support rod and the right-angled crank to the connection point of the first ear plate and the right-angled crank.

[0027] The present invention also discloses an open arrangement frame for a self-resetting damper, including an open arrangement device for the self-resetting damper, as well as two parallel frame columns and two parallel frame beams.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] This invention utilizes a self-resetting damper as a core energy-dissipating component. Under seismic loading, it dissipates seismic energy through its own deformation, effectively reducing energy accumulation in the structure and minimizing structural damage. After an earthquake, only the self-resetting damper needs replacement; the force-transmitting components are reusable, improving component utilization and reducing post-earthquake repair costs. The support rod and right-angle curved rod are rotatably connected, participating in force transmission and transferring the force generated by the seismic frame to the right-angle curved rod. After the force is transmitted to the right-angle curved rod, it rotates around its connection point with the first ear plate. This rotation causes relative lateral displacement at both ends of the self-resetting damper, resulting in axial tensile and compressive deformation. This axial tensile and compressive deformation is greater than in traditional arrangements, providing a larger displacement deformation condition for the self-resetting damper, thereby improving its energy dissipation effect and enhancing the overall structure's vibration reduction performance. This invention, through the rotation mechanism of the right-angle curved rod, provides greater displacement deformation conditions for the self-resetting damper, improving energy dissipation. The open-type arrangement is flexible, occupies less space, and can better meet building functional requirements, exhibiting strong adaptability. This invention effectively solves the technical problems of limited relative displacement at both ends of a self-resetting component, the limitation of energy dissipation performance under small displacement conditions due to the restoring force within the component, and the large space occupation of traditional self-resetting components. As an energy-dissipating component, the self-resetting damper effectively dissipates seismic energy under earthquake action, controls residual deformation of the structure after the earthquake, and enables rapid functional recovery of the structure after an earthquake, significantly improving the overall vibration reduction effect and seismic performance. This invention is easy to install, has a simple overall structure, and is convenient to maintain after an earthquake, requiring only the replacement of the self-resetting damper, thus reducing maintenance costs and time.

[0035] The frame columns and beams of this invention form the basic skeleton of the entire building structure, providing a stable installation space and load-bearing platform for the open-type arrangement of the self-resetting dampers. The frame structure possesses good integrity and spatial load-bearing performance, capable of withstanding vertical and horizontal loads, ensuring the structure's safety under normal use and extreme conditions such as earthquakes. The space formed by the frame columns and beams can be used to arrange various functional areas of the building, meeting the building's usage requirements. Simultaneously, the form of the frame structure provides a reasonable spatial range and constraints for the arrangement of the self-resetting dampers. Under extreme loads such as earthquakes, the frame structure transfers the load to the open-type arrangement of the self-resetting dampers through the first, second, and third ear plates. This allows the open-type arrangement of the self-resetting dampers, together with the frame beams, to resist earthquake forces, enhancing the overall seismic performance of the structure and ensuring the stability of the frame columns. This invention rationally applies an open-type arrangement of self-resetting dampers to frame structures. Utilizing the energy dissipation and self-resetting function of the dampers, it effectively absorbs and dissipates seismic energy, reducing damage and deformation of the frame structure under seismic loads. This avoids localized stress concentration and unreasonable stress distribution in the frame structure, lowering the risk of collapse during earthquakes, controlling residual deformation after earthquakes, and improving the structure's post-earthquake functional recoverability, thus significantly improving the structure's seismic performance. This invention can be flexibly adjusted according to different building requirements and structural forms. The third ear plate can be connected to another frame beam or a frame column near a right-angle curved rod, adapting to different building layouts and structural requirements, thus improving its versatility and adaptability in engineering applications. The frame structure of this invention is simple, the construction technology is mature, and it requires no complex construction equipment or processes. Furthermore, during post-earthquake maintenance, the replaceable self-resetting dampers and reusable force-transmitting components facilitate the inspection and replacement of damaged parts, reducing maintenance costs and time.

[0053] The present invention will now be described in further detail with reference to the accompanying drawings:

[0054] Example 1:

[0055] See Figure 1 This embodiment discloses an open arrangement device for a self-resetting damper, including: a self-resetting damper 4, a right-angle curved rod 5, a support rod 6, a first ear plate 7, a second ear plate 8, and a third ear plate 9. One end of the self-resetting damper 4 is rotatably connected to the right-angle curved rod 5. One end of the support rod 6 is rotatably connected to the right-angle curved rod 5. The first ear plate 7 is rotatably connected to the right-angle curved rod 5. The second ear plate 8 is rotatably connected to the other end of the self-resetting damper 4. The third ear plate 9 is rotatably connected to the other end of the support rod 6.

[0056] As a core energy-dissipating component, the self-resetting damper 4 dissipates seismic energy through its own deformation under earthquake action, effectively reducing energy accumulation in the structure and minimizing structural damage. After an earthquake, only the self-resetting damper 4 needs to be replaced, as the force-transmitting components can be reused, improving component utilization and reducing post-earthquake repair costs.

[0057] See Figure 5 and Figure 6 In this embodiment of the invention, the self-resetting damper 4 includes: an outer cylinder 41, a force-transmitting screw 42, a disc spring 44, an inner cylinder 46, an inner cylinder connecting section 48, and several sets of U-shaped energy-dissipating plates 49. See also... Figure 7 This is a schematic diagram of the outer cylinder 41. Figure 8This is an assembly drawing of disc spring 44 and force transmission screw 42. Figure 9 This is a schematic diagram of the inner cylinder 46.

[0058] The inner cylinder connecting section 48 is fixedly connected to the inner cylinder 46. The inner cylinder connecting section 48 is embedded in the outer cylinder 41. The outer cylinder 41 and the inner cylinder connecting section 48 are connected by a plurality of sets of U-shaped energy-consuming plates 49. The outer cylinder 41 is rotatably connected to the right-angle curved rod 5. The inner cylinder 46 is rotatably connected to the second ear plate 8. The force transmission screw 42 passes through the outer cylinder 41, the inner cylinder connecting section 48 and the inner cylinder 46 in sequence. The force transmission screw 42 is provided with an outer cylinder bottom plate 54 and a limiting component. The outer cylinder bottom plate 54 is fixedly connected to the outer cylinder 41. The limiting component is located in the inner cylinder 46. A disc spring 44 is provided between the outer cylinder bottom plate 54 and the inner cylinder 46. A disc spring 44 is provided between the inner cylinder connecting section 48 and the limiting component.

[0059] See Figure 6 In this embodiment of the invention, the inner cylinder 46 is provided with an inner cylinder ear plate 47, and the inner cylinder ear plate 47 is rotatably connected to the second ear plate 8;

[0060] The outer cylinder bottom plate 54 is provided with an outer cylinder ear plate 43, which is rotatably connected to the right-angle curved rod 5.

[0061] See Figure 9 In this embodiment of the invention, the inner cylinder connecting section 48 includes a first connecting plate 51, a second connecting plate 52, and a connecting cylinder 53. The first connecting plate 51 is fixedly connected to the second connecting plate 52 through the connecting cylinder 53. The force transmission screw 42 passes through the first connecting plate 51, the second connecting plate 52, and the connecting cylinder 53. The first connecting plate 51 is fixedly connected to the inner cylinder 46. Several sets of U-shaped energy-dissipating plates 49 are symmetrically arranged on both sides of the connecting cylinder 53. The connecting cylinder 53 is fixedly connected to the outer cylinder 41 through several sets of U-shaped energy-dissipating plates 49. A disc spring 44 is provided between the outer cylinder ear plate 43 and the second connecting plate 52. A disc spring 44 is provided between the first connecting plate 51 and the limiting component.

[0062] See Figure 9 In this embodiment of the invention, a first stiffening rib 55 is provided between the first connecting plate 51 and the connecting cylinder 53, and a first stiffening rib 55 is provided between the second connecting plate 52 and the connecting cylinder 53.

[0063] See Figure 6 In this embodiment of the invention, each group of the U-shaped energy-consuming plates 49 consists of two plates, and the two U-shaped energy-consuming plates 49 are arranged opposite to each other.

[0064] See Figure 6 and Figure 8In this embodiment of the invention, the limiting component is a nut 45, and the nut 45 is connected to the force transmission screw 42 by a thread.

[0065] In this embodiment of the invention, the connection points of the first ear plate 7 and the right-angle curved rod 5, the connection points of the self-resetting damper 4 and the right-angle curved rod 5, the connection points of the support rod 6 and the right-angle curved rod 5, the connection points of the second ear plate 8 and the self-resetting damper 4, and the connection points of the third ear plate 9 and the support rod 6 are located on the same plane.

[0066] The distance from the connection point of the self-resetting damper 4 and the right-angle curved rod 5 to the connection point of the first ear plate 7 and the right-angle curved rod 5 is greater than the distance from the connection point of the support rod 6 and the right-angle curved rod 5 to the connection point of the first ear plate 7 and the right-angle curved rod 5.

[0067] See Figure 1 The support rod 6 is rotatably connected to the right-angle curved rod 5, participating in force transmission and transferring the force generated by the seismic frame to the right-angle curved rod 5. After the force is transmitted to the right-angle curved rod 5, the right-angle curved rod 5 rotates around the connection point with the first ear plate 7. The rotation of the right-angle curved rod 5 causes relative deformation at both ends of the self-resetting damper 4, resulting in axial tensile and compressive deformation of the self-resetting damper 4. The amount of axial tensile and compressive deformation is higher than that of the traditional arrangement, providing greater displacement deformation conditions for the self-resetting damper 4, thereby improving the energy dissipation effect of the self-resetting damper and enhancing the overall vibration reduction effect of the structure. The connection points of the first ear plate 7 and the right-angle curved rod 5, the connection points of the self-resetting damper 4 and the right-angle curved rod 5, and the connection points of the support rod 6 and the right-angle curved rod 5 are located at the three vertices of a right-angled triangle, and the connection point of the first ear plate 7 and the right-angle curved rod 5 is the right-angle vertex of the right-angled triangle, ensuring that the self-resetting damper 4 can only undergo in-plane rotational deformation. The first ear plate 7 and the second ear plate 8 are used to fix and connect the same frame beam 3. The third ear plate 9 is used to fix the frame column or the adjacent frame beam 3 of the frame beam 3 that is fixedly connected to the second ear plate 8.

[0068] In this embodiment of the invention, the self-resetting damper 4, the support rod 6, and the first ear plate 7 are rotatably connected to the right-angle curved rod 5 via pins or ball joints.

[0069] This invention utilizes the rotation mechanism of the right-angle curved rod 5 to provide greater displacement and deformation conditions for the self-resetting damper 4, thereby improving energy dissipation. The open-type arrangement offers flexibility, occupies less space, effectively meets building functional requirements, and is highly adaptable. It effectively solves the technical problems of limited relative displacement at both ends of the self-resetting component, the limiting energy dissipation performance of the component under small displacement conditions due to the restoring force within the self-resetting component, and the large space occupation of traditional self-resetting component arrangements. As an energy dissipation component, the self-resetting damper 4 effectively dissipates seismic energy under earthquake action, controls residual post-earthquake deformation of the structure, and enables rapid post-earthquake functional recovery, significantly improving the overall structure's damping effect and seismic performance.

[0070] This invention is easy to install and has a simple overall structure. It uses an ear plate-pin connection node, eliminating the need for complex construction processes and significantly shortening the construction period. Post-earthquake maintenance is convenient; only the self-resetting damper 4 needs to be replaced. The force transmission components are reusable, reducing maintenance costs and time.

[0071] This invention can be used in new structures to provide reliable seismic protection for new buildings; it can also be used in the reinforcement, renovation and upgrading of traditional structures to improve the seismic performance of existing buildings, and has good application prospects and market value.

[0072] See Figure 2 This invention also discloses an open-type frame for a self-resetting damper, including an open-type arrangement device for the self-resetting damper, two parallel frame columns 2 and two parallel frame beams 3, which are fixedly connected to form a frame structure 1. The frame columns 2 and frame beams 3 constitute the basic skeleton of the entire building structure, providing a stable installation space and load-bearing platform for the open-type arrangement device of the self-resetting damper. The frame structure 1 has good integrity and spatial stress performance, and can withstand vertical and horizontal loads, ensuring the safety of the structure under normal use and extreme conditions such as earthquakes. The space formed by the frame columns 2 and frame beams 3 can be used to arrange various building functional areas to meet the building's usage requirements. At the same time, the form of the frame structure 1 also provides a reasonable spatial range and constraints for the arrangement of the self-resetting damper 4.

[0073] The first ear plate 7 and the second ear plate 8 are fixedly connected to the same frame beam 3. Under the action of earthquakes, the frame structure 1 transmits the load to the open arrangement device of the self-resetting damper through the first ear plate 7, the second ear plate 8 and the third ear plate 9. Specifically, the frame beam 3 transmits the load to the self-resetting damper 4 through the first ear plate 7 and the second ear plate 8, so that the self-resetting damper 4 and the frame beam 3 jointly resist the earthquake action, thereby enhancing the overall seismic performance of the structure.

[0074] See Figure 3 , Figure 10 and Figure 14 The third ear plate 9 is fixedly connected to the frame column near the right-angled curved rod 5. The frame column 2, as a vertical support member of the structure, bears a high load-bearing capacity. The connection between the third ear plate 9 and the frame column 2 effectively transfers the force on the frame column 2 to the right-angled curved rod 5, reducing the deformation and stress of the frame column 2 and ensuring its stability. (See also...) Figure 11 This is a schematic diagram illustrating the deformation principle of the open-type arrangement frame of the self-resetting damper of the present invention.

[0075] In this embodiment of the invention, the frame beam 3 connected to the first ear plate 7 and the second ear plate 8 is provided with a second stiffening rib 15 and a third stiffening rib 16. The second stiffening rib 15 is located at the connection between the frame beam 3 and the first ear plate 7, and the third stiffening rib 16 is located at the connection between the frame beam 3 and the second ear plate 8.

[0076] In this embodiment of the invention, the third ear plate 9 is connected to the frame column 2, and the frame column 2 is provided with a fourth stiffening rib 17, which is located at the connection between the third ear plate 9 and the frame column 2.

[0077] This invention rationally applies an open-type arrangement of self-resetting dampers to the frame structure 1. Utilizing the energy dissipation and self-resetting functions of the self-resetting dampers 4, it effectively absorbs and dissipates seismic energy, reducing damage and deformation of the frame structure 1 under seismic loads. Simultaneously, the frame structure 1 and the open-type arrangement of the self-resetting dampers cooperate to form an organic whole, jointly resisting seismic forces, significantly improving the structure's seismic performance, reducing the risk of frame structure 1 collapsing during earthquakes, and ensuring the safety of personnel and the normal use of the building.

[0078] The force distribution mode of the frame structure 1 of the present invention can reasonably transfer the load to the self-resetting damper 4, realize the concentrated energy dissipation of the self-resetting damper, and avoid the situation of local stress concentration and unreasonable force distribution in the frame structure 1.

[0079] This invention can be flexibly adjusted according to different building requirements and structural forms. The third ear plate 9 can be connected to another frame beam 3 or a frame column near the right-angle curved rod 5 according to the actual situation, which can adapt to different building layouts and structural requirements, and improve its versatility and adaptability in engineering applications.

[0080] The present invention features a simple frame structure and mature construction technology. The open-type arrangement of the self-resetting damper uses standard connecting parts such as ear plates, making installation convenient and requiring no complex construction equipment or processes. Furthermore, during post-earthquake maintenance, the self-resetting damper 4 is replaceable, and the force transmission components are reusable, facilitating the inspection and replacement of damaged parts and reducing maintenance costs and time.

[0081] Example 2:

[0082] See Figure 12 and Figure 13 This embodiment provides an open-type frame for a self-resetting damper. Unlike embodiment 1, in this embodiment, the third ear plate 9 is fixedly connected to another frame beam 3. This further transfers the force of the entire frame structure to the open-type self-resetting damper, making the stress on the structure more uniform and reasonable, forming a complete stress system, and improving the overall stability and seismic resistance of the structure under loads such as earthquakes.

[0083] In this embodiment of the invention, the frame beam 3 is provided with a fourth stiffening rib 17, and the fourth stiffening rib 17 is located at the connection between the third ear plate 9 and the frame beam 3.

[0084] Example 3:

[0085] See Figures 2 to 9 The purpose of this invention is to provide an open-type frame with self-resetting dampers. This arrangement offers significant displacement amplification while occupying minimal space, effectively improving building space utilization. By employing metal dampers to dissipate seismic energy and using self-resetting technology to control post-earthquake residual deformation, the invention achieves efficient energy dissipation and controllable post-earthquake residual deformation. This directly solves the problems existing in current technologies.

[0086] To achieve the above objectives, this invention employs an open-type installation arrangement for the self-resetting damper 4 in a traditional frame structure 1. First, a right-angled curved rod 5 is installed on the frame beam 3. One end of the self-resetting damper 4 is connected to the right-angled curved rod 5, and the other end is connected to the frame beam 3 or a frame node. One end of the support rod 6 is connected to the right-angled curved rod 5, and the other end is connected to a frame column or a frame node. The connections between the support rod 6 and the frame, the self-resetting damper 4 and the frame, and the right-angled curved rod 5 and the frame beam 3 are all made using pin-and-ear plate connections, ensuring that only in-plane rotational deformation occurs. To accommodate the open-type installation, a self-resetting damper 4 is proposed, employing a metal U-shaped energy-dissipating plate 49 with axial yielding to provide energy dissipation capacity and a disc spring 44 to provide reset capacity, thereby achieving efficient energy dissipation and controllable residual deformation of the structure.

[0087] The frame structure 1 of this invention consists of a left-side frame column, a right-side frame column, and a frame beam 3. A self-resetting damper 4 is installed within the frame structure 1. One end of the self-resetting damper 4 is connected to a right-angled curved rod 5, and the other end is connected to the frame beam 3. One end of a support rod 6 is connected to the right-angled curved rod 5, and the other end is connected to the left-side frame column. When the structure undergoes lateral deformation, the right-angled curved rod 5 rotates, thereby causing the self-resetting damper 4 to rotate, resulting in axial tensile and compressive deformation at both ends of the self-resetting damper.

[0088] The first ear plate 7 and the second ear plate 8 are fixed at corresponding positions on the frame beam 3, respectively. The right-angle curved rod 5 is connected to the frame beam 3 via the third pin 12 and the first ear plate 7. One end of the self-resetting damper is connected to the frame beam 3 via the second ear plate 8 and the fourth pin 13, and the other end is connected to the right-angle curved rod 5 via the second pin 11. The second stiffening rib 15 and the third stiffening rib 16 are provided at the corresponding positions on the frame beam 3 of the first ear plate 7 and the second ear plate 8.

[0089] A third ear plate 9 is installed on the left-side frame column. One end of the support rod 6 is connected to the left-side frame column 2 via the third ear plate 9 and the fifth pin 14, and the other end of the support rod 6 is connected to the right-angle curved rod 5 via the first pin 10. A fourth stiffening rib 17 is installed at the position of the frame column corresponding to the third ear plate 9.

[0090] The center lines connecting the first pin 10, the second pin 11, and the third pin 12 form a right triangle, with the third pin 12 at the right angle.

[0091] See Figure 5 and Figure 6 The self-resetting damper 4 consists of an outer cylinder 41, a force transmission screw 42, an outer cylinder lug 43, a disc spring 44, a nut 45, an inner cylinder 46, an inner cylinder lug 47, an inner cylinder connecting section 48, a U-shaped energy dissipation plate 49, and high-strength bolts 50. The self-resetting damper 4 can be replaced with other types of self-resetting dampers.

[0092] Frame beam 3, left frame column 2 and right frame column 2 can be made of high-strength steel with a yield strength of not less than 355MPa.

[0093] The present invention uses the rotation of the right-angle curved rod 5 to drive the two ends of the self-resetting damper 4 to move relative to each other, so that the self-resetting damper 4 will produce axial tensile and compressive deformation. The amount of axial tensile and compressive deformation is higher than that of the traditional arrangement, which can provide greater displacement deformation conditions for the self-resetting damper 4, improve the energy dissipation effect of the self-resetting damper, and thus improve the vibration reduction effect of the overall structure.

[0094] The open-type frame of the self-resetting damper of this invention is very flexible, occupies less space, can better meet the functional requirements of buildings, and has strong adaptability.

[0095] The self-resetting damper 4 proposed in this invention is installed in the frame structure 1 as an energy dissipation component. Under earthquake action, the self-resetting component dissipates earthquake energy, which can effectively dissipate earthquake energy and effectively control the residual deformation of the structure after the earthquake, so as to realize the rapid recovery of the structure's function after the earthquake.

[0096] The self-resetting damper 4 proposed in this invention uses a U-shaped energy-dissipating plate 49 as the energy-dissipating component, which can fully utilize the deformation and energy-dissipating properties of steel, and has the advantages of strong deformation capacity and stable performance. It uses a disc spring 44 as the reset component, which has the advantages of flexible stiffness adjustment and good durability. After an earthquake, only the energy-dissipating component in the self-resetting damper needs to be replaced; the reset and force-transmitting components can be reused, resulting in high utilization.

[0097] The open-type arrangement of the self-resetting damper proposed in this invention is convenient to install, has a simple overall structure, and is easy to operate. It adopts an ear plate-pin connection node, a connection method well-known in the engineering field, requiring no modification to the main structure and facilitating disassembly after an earthquake. This completely avoids on-site wet work and significantly shortens the construction period.

[0098] The open-type arrangement device of the self-resetting damper proposed in this invention can be used for both new structures and reinforcement, renovation and upgrading projects of traditional structures, and has good seismic performance.

[0099] Example 4:

[0100] See Figures 2 to 9 This invention discloses an open-type arrangement frame for a self-resetting damper. Figure 2 This is a schematic diagram of a typical single-span, open-type frame with a self-resetting damper, including a left-side frame column, a right-side frame column, frame beam 3, a self-resetting damper 4, a right-angle curved rod 5, a support rod 6, a first ear plate 7, a second ear plate 8, a third ear plate 9, a first pin 10, a second pin 11, a third pin 12, a fourth pin 13, a fifth pin 14, a second stiffening rib 15, a third stiffening rib 16, and a fourth stiffening rib 17. The first ear plate 7, second ear plate 8, second stiffening rib 15, and third stiffening rib 16 are pre-welded to the corresponding positions on frame beam 3 during factory fabrication. The third ear plate 9 and fourth stiffening rib 17 are pre-welded to the corresponding positions on the left-side frame column during factory fabrication. The bolt holes for the first ear plate 7, second ear plate 8, and third ear plate 9 are pre-fabricated in the factory. During on-site installation, only the following steps are required: Figure 2 As shown, assembling the pin and the corresponding lug together achieves an effective connection.

[0101] Figure 3 This is an elevation layout diagram of an open-type frame structure with self-resetting dampers. Figure 4 This is a plan view of the open-type arrangement of the self-resetting damper frame structure. In actual use, the self-resetting damper 4 is arranged in an open-type arrangement within the frame formed by part of the frame beam 3 and frame column 2. Figure 3 and Figure 4 The dashed box in the figure represents an open-type arrangement frame of a complete self-resetting damper according to the present invention. The present invention can be used for the construction and reinforcement / renovation of frame structure 1.

[0102] Figure 5 and Figure 6 This invention uses a self-resetting damper 4, which is manufactured in accordance with... Figure 6 As shown, first, the disc spring 44 and nut 45 are installed on the force transmission screw 42, then the inner cylinder is installed in the corresponding position. After that, the corresponding plates of the inner cylinder 46 and the outer cylinder 41 are connected by the U-shaped energy dissipation plate 49 and high-strength bolts 50. Finally, the outer cylinder ear plate 43 and the inner cylinder ear plate 47 are installed.

[0103] When the self-resetting damper 4 is subjected to axial tension, the inner cylinder 46 stretches, causing the U-shaped energy-dissipating plate 49 to deform axially outward, thereby compressing the disc spring 44 in the inner cylinder 46. When the self-resetting damper 4 is subjected to axial compression, the inner cylinder 46 compresses, causing the U-shaped energy-dissipating plate 49 to deform axially inward, thereby compressing the disc spring 44 in the outer cylinder 41. The compression of the disc spring 44 effectively controls the residual deformation of the self-resetting damper 4, thereby reducing the residual deformation of the structure. See also Figure 7 This is a schematic diagram of the outer cylinder 41. Figure 8 This is an assembly drawing of disc spring 44 and force transmission screw 42. Figure 9 This is a schematic diagram of the inner cylinder 46.

[0104] Figure 6 This is a deformation mechanism diagram of a single-span, open-type steel frame with self-resetting dampers. Under seismic loading, the structure undergoes limited lateral deformation. Based on the assumption of small deformation, the assembly method of the self-resetting damper 4 proposed in this invention can effectively amplify the relative deformation at both ends of the damper, allowing the structure to fully dissipate seismic energy through plasticity.

[0105] In the event of a strong earthquake, structural damage is primarily concentrated in the self-resetting damper 4, while other components remain in an elastic or slightly plastic state. By quickly replacing the self-resetting damper 4, structural function can be rapidly restored.

[0106] The above content is only for illustrating the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made to the technical solution based on the technical concept proposed in this invention shall fall within the scope of protection of this invention.
