Description

Technical Field

[0001] This invention relates to the field of building energy dissipation and vibration reduction, specifically to a metal energy-dissipating support that saves building material consumption and has high energy density. Background Technology

[0002] Metal energy dissipation devices are used for vibration reduction in building structures. They absorb external forces such as earthquakes through the plastic deformation of metallic materials, reducing the amplitude of structural vibrations and achieving a damping effect. Their main working principle utilizes the plastic deformation characteristics of metallic materials. When a building structure is subjected to external forces such as earthquakes, the metallic material inside the energy dissipation device undergoes plastic deformation, absorbing some of the seismic energy and converting it into heat energy, thereby reducing the amplitude of structural vibrations. Metal energy dissipation devices exhibit stable performance, unaffected by factors such as temperature, humidity, and frequency. They possess good durability and fatigue resistance, making them suitable for various types of buildings and seismic intensity zones. They can be designed and manufactured according to different building structures and environmental conditions, demonstrating strong adaptability.

[0003] Existing metal energy dissipation devices mainly include two types: metal dampers and buckling-restrained braces. Metal dampers dissipate seismic energy through the shear or bending deformation of a metal energy-dissipating plate, and are typically installed using A-frame braces or concrete piers, consuming a significant amount of steel and concrete. Buckling-restrained braces dissipate seismic energy through the tensile and compressive deformation of a metal core plate. The outer sleeve is used to prevent buckling of the core plate. Under the same tensile and compressive deformation, the longer the brace, the smaller the strain, and the lower its energy dissipation density.

[0004] Existing metal dampers and buckling-restrained braces have certain limitations in practical applications, as follows:

[0005] Metal dampers: They are installed using A-frame bracing or concrete piers, which consumes a large amount of steel and concrete. Dampers of different sizes and parameters need to be analyzed, designed and manufactured separately, which increases research and development costs and limits manufacturing efficiency.

[0006] Buckling-restrained braces: Under the same tensile and compressive deformation, the longer the brace, the smaller the strain and the smaller the energy density. The brace is generally long, making it difficult to process, transport, hoist, and install. High processing accuracy is required; otherwise, mismatched connection holes at both ends of the brace will prevent installation.

[0007] To address the shortcomings of existing metal dampers and buckling-restrained braces, several improvement schemes have been proposed. For example, Chinese invention patent CN112503125A proposes a helical friction-type metal damper, which includes a helical rod assembly, multiple energy dissipation sections, multiple self-resetting sections, and an outer sleeve assembly. It dissipates seismic energy by converting it into heat energy through friction between the rotating plates in the energy dissipation section and the outer sleeve assembly. However, this friction-based metal damper suffers from reliability issues in practical applications, with the possibility of failure; furthermore, relying on friction for energy dissipation results in low energy density and limited practicality.

[0008] Therefore, how to effectively reduce the consumption of building materials for metal energy-consuming supports, increase energy density, and reduce installation difficulty has become an urgent problem to be solved in this field. Summary of the Invention

[0009] To address the problems of low energy density and inconvenient installation of existing metal energy-dissipating supports, the present invention aims to provide a metal energy-dissipating support that saves building materials, has high energy density, and is easy to install.

[0010] To achieve the above objectives, the present invention provides a metal energy-dissipating support, including an outer sleeve connecting end, an inner core rod connecting end, and at least one set of energy-dissipating modules;

[0011] The energy-consuming module includes an outer sleeve and an inner core rod. A metal energy-consuming plate is disposed on the inner core rod, and an energy-consuming limiting component is disposed on the inner wall of the outer sleeve. The inner core rod is placed in the outer sleeve, and a limiting fit is formed between the metal energy-consuming plate on the inner core rod and the energy-consuming limiting component on the inner wall of the outer sleeve. When the inner core rod and the outer sleeve move relative to each other in the axial direction, the metal energy-consuming plate on the inner core rod will undergo bending deformation.

[0012] The outer sleeve connecting end is connected to one end of the outer sleeve and forms a certain gap with the inner core rod inside the outer sleeve; the inner core rod is connected to the inner core rod inside the other end of the outer sleeve and forms a certain gap with the other end of the outer sleeve.

[0013] In some embodiments of the present invention, the metal energy-dissipating plates on the inner core rod are distributed continuously along the extension direction of the inner core rod.

[0014] In some embodiments of the present invention, the energy-consuming limiting components on the inner wall of the outer sleeve are distributed continuously along the extension direction of the outer sleeve.

[0015] In some embodiments of the present invention, the metal energy-dissipating plates on the inner core rod are distributed continuously around the inner core rod in a spiral structure along the extension direction of the inner core rod.

[0016] In some embodiments of the present invention, the energy-consuming limiting components on the inner wall of the outer sleeve adopt a spiral structure and are continuously distributed on the inner wall of the outer sleeve along the extension direction of the outer sleeve.

[0017] In some embodiments of the present invention, the outer sleeve connecting end is connected to one end of the outer sleeve using a spiral connection structure.

[0018] In some embodiments of the present invention, the inner core rod is connected to the inner core rod at the other end of the outer sleeve by a spiral connection structure.

[0019] In some embodiments of the present invention, multiple energy-consuming modules in the metal energy-consuming support are sequentially connected and combined together based on a detachable connection structure to form a multi-level energy-consuming module.

[0020] In some embodiments of the present invention, in the multi-stage energy-consuming modules, the outer sleeves of adjacent energy-consuming modules are detachably connected and combined; the inner core rods of adjacent energy-consuming modules are also detachably connected and combined.

[0021] The metal energy dissipation brace provided by this invention effectively combines the advantages of traditional metal dampers and buckling restraint braces by adopting an energy dissipation brace form and dissipating seismic energy through metal bending deformation. Furthermore, it adopts a modular assembly method, which greatly improves its practicality.

[0022] The metal energy-dissipating support provided by this invention has the following technical advantages over existing solutions in practical applications:

[0023] 1) Save on building materials and improve installation efficiency;

[0024] 2) Energy consumption density and vibration reduction effect can be greatly improved, which can effectively reduce building seismic response and damage;

[0025] 3) The ultra-long support can be processed, transported, hoisted and installed in sections, which greatly reduces the difficulty of each link and saves costs and time;

[0026] 4) Standardized production is possible, allowing for flexible combinations to adapt to various application scenarios and installation locations;

[0027] 5) It has an installation error tolerance mechanism, which can enable smooth installation under certain dimensional deviations. Attached Figure Description

[0046] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0047] To address the problems of existing metal dampers or buckling-restrained braces, this invention abandons the design scheme of existing energy-dissipating braces that mainly rely on the tensile and compressive deformation of metal to dissipate seismic energy. Based on the support connection form, it innovatively adopts a spiral metal energy-dissipating sheet as the main energy-dissipating element, which converts the tensile and compressive deformation of metal into the bending deformation of metal to dissipate seismic energy. This effectively increases the energy dissipation density, and at the same time, based on the support connection structure, it effectively saves a large amount of steel or concrete materials used for connection.

[0048] See Figure 1a and Figure 1b The diagram shows an example of the construction of a novel metal energy-dissipating support provided by the present invention.

[0049] As shown in the figure, this metal energy-dissipating support mainly consists of the outer sleeve connecting end 1, the inner core rod connecting end 2, the outer sleeve 3, and the inner core rod 4.

[0050] The outer sleeve 3 is a hollow structure, used to support other components to form the main structure for energy dissipation support.

[0051] To facilitate combination with the inner core rod 4, an energy-consuming limiting component is provided on the inner wall of the outer sleeve 3. This energy-consuming limiting component can cooperate with the metal energy-consuming plate on the inner core rod 4 to limit the movement of the metal energy-consuming plate along the axial direction of the outer sleeve 3.

[0052] The specific structural form of the outer sleeve 3 is not limited here, as long as it meets the above structural characteristics.

[0053] In conjunction with this, the inner core rod 4 of this metal energy-dissipating support serves as the main energy-dissipating component, on which a corresponding metal energy-dissipating plate is mounted. The inner core rod 4 is integrally housed within the outer sleeve 3, and the metal energy-dissipating plate on it forms a limiting fit with the energy-dissipating limiting component on the inner wall of the outer sleeve 3, thereby forming an energy-dissipating module. When the energy-dissipating module is subjected to force, causing relative axial movement between the inner core rod 4 and the outer sleeve 3, the metal energy-dissipating plate on the inner core rod 4 and the energy-dissipating limiting component on the inner wall of the outer sleeve 3 will generate limiting interference in the axial movement. Under the limiting interference of the energy-dissipating limiting component on the inner wall of the outer sleeve 3, the metal energy-dissipating plate on the inner core rod 4 will undergo bending deformation to dissipate energy.

[0054] In this metal energy-dissipating support, the outer sleeve connecting end 1 and the inner core rod connecting end 2 serve as connecting components, which are located at both ends of the energy-dissipating module formed by the outer sleeve 3 and the inner core rod 4, respectively, and are used to connect with the corresponding main structure to be supported.

[0055] The outer sleeve connecting end 1 is located at one end of the energy-consuming module and has a certain gap between it and the nearest inner core rod 4 in the energy-consuming module. The inner core rod connecting end 2 is located at the other end of the energy-consuming module and has a certain gap between it and the nearest outer sleeve 3 in the energy-consuming module, serving as a reserved space to support compression deformation.

[0056] Specifically, the outer sleeve connecting end 1 is connected only to the outer sleeve 3 at one end of the energy-consuming module, and is not connected to the inner core rod 4 in the energy-consuming module, with a certain gap between the two; at the same time, the inner core rod connecting end 2 is connected only to the inner core rod 4 at the other end of the energy-consuming module, and is not connected to the outer sleeve 3 in that end of the energy-consuming module, with a certain gap between the two, as a reserved space to support compression deformation.

[0057] The outer sleeve connecting end 1 and the inner core rod connecting end 2, as configured in this way, can transmit the force received to the inner core rod 4 or the outer sleeve 3, so that the inner core rod 4 and the outer sleeve 3 can generate axial relative movement. Based on the axial limiting cooperation between the two, the metal energy-dissipating plate on the inner core rod 4 is bent and deformed to dissipate energy.

[0058] In some embodiments of the present invention, in order to improve the energy dissipation effect of the metal bending deformation between the inner core rod 4 and the outer sleeve 3 in the energy dissipation module, the metal energy dissipation plates on the inner core rod 4 are distributed continuously around the inner core rod 4. At the same time, the energy dissipation limiting components on the inner wall of the outer sleeve 3 are simultaneously distributed continuously on the inner wall of the outer sleeve 3.

[0059] Specifically, the metal energy-consuming plates on the inner core rod 4 are distributed continuously around the inner core rod 4 in a spiral structure along the extension direction of the inner core rod 4; furthermore, the energy-consuming limiting components on the inner wall of the outer sleeve 3 are also distributed continuously on the inner wall of the outer sleeve 3 in a matching spiral structure along the extension direction of the outer sleeve 3.

[0060] This greatly increases the contact area between the metal energy-consuming plate on the inner core rod 4 and the energy-consuming limiting component on the inner wall of the outer sleeve 3, thereby significantly improving the energy-consuming effect of metal bending deformation.

[0061] In some embodiments of the present invention, the connection between the outer sleeve connecting end 1 and the outer sleeve 3 is preferably a spiral connection, and the connection between the inner core rod connecting end 2 and the inner core rod 4 is also preferably a spiral connection. This forms an adjustable assembly connection structure, which enables the metal energy dissipation support to have an installation error tolerance mechanism. Based on the adjustable spiral connection structure, the metal energy dissipation support can be finely adjusted in length during installation by rotating the corresponding connecting ends, thus achieving smooth installation under certain dimensional deviations.

[0062] Based on this, the proposed solution can be further optimized to improve the performance of the metal energy-dissipating support.

[0063] For the construction scheme of metal energy dissipation supports, a modular assembly design can be adopted. By flexibly combining modular standard components, energy dissipation supports of different sizes and parameters can be formed, which can be adapted to various occasions and are flexible and convenient to install.

[0064] The prefabricated structure design of the core rod, sleeve and connecting end allows for segmented processing, transportation, hoisting and installation of the ultra-long support, greatly reducing the difficulty of each step and saving costs and time.

[0065] Based on this, the core rod and sleeve are constructed according to a standardized modular design, forming a series of standardized energy-consuming module components. These components have different dimensions and parameters. Furthermore, the spiral metal energy-consuming plates (i.e., metal energy-consuming plates) on the core rod have different thicknesses and pitches, enabling standardized production. In practical applications, the flexible combination of components of different specifications allows for flexible adjustment of support dimensions and energy consumption parameters, adapting to various application scenarios and installation locations.

[0066] The corresponding metal energy-dissipating support can be assembled from multiple energy-dissipating modules. Each energy-dissipating module can be freely selected and flexibly combined from a series of standard modular components to achieve flexible adjustment of support size and energy dissipation parameters, adapting to various application scenarios and installation locations.

[0067] Furthermore, the size and pitch of the spiral metal energy-consuming plates on the core rod in each energy-consuming module are adjustable. At the same time, based on the parallel structure between each coil of energy-consuming plates, under the same support deformation, the energy consumption of each coil of energy-consuming plates is superimposed, and the energy consumption density can be greatly improved.

[0068] As can be seen from the above, the metal energy-dissipating support scheme proposed in this invention utilizes the bending deformation of metal to dissipate seismic energy. The longer the support (the more metal energy-dissipating plates), the greater the energy dissipation density. This support scheme combines the advantages of traditional metal dampers and buckling-restrained braces, fully utilizing the energy dissipation function of metal while employing a support connection method that saves a large amount of steel or concrete materials used for connections.

[0069] The implementation process of the metal energy-dissipating support scheme provided by this invention will be further illustrated below through corresponding examples.

[0070] See Figures 1a-1c The figure shown is an example of the overall structure of the metal energy dissipation support given in this example.

[0071] Based on the diagram, the metal energy-dissipating support given in this example mainly includes an outer sleeve connecting end 1, an inner core rod connecting end 2, several outer sleeves 3, and several inner core rods 4.

[0072] One of the inner core rods 4 is placed in an outer sleeve 3 to form an energy-consuming module, thereby forming multiple energy-consuming modules.

[0073] Based on this, multiple energy-consuming modules are sequentially connected and combined using a detachable connection structure to form a multi-level energy-consuming module.

[0074] It should be noted that when multiple energy-consuming modules are connected and combined sequentially, the outer sleeves 3 of adjacent energy-consuming modules are detachably connected and combined. At the same time, the inner core rods 4 of adjacent energy-consuming modules are also detachably connected and combined. Thus, in the multi-stage energy-consuming module, the corresponding multiple outer sleeves 3 are connected sequentially to form a whole, and the multiple inner core rods 4 are also connected sequentially to form a whole. They can move synchronously within the outer sleeve and undergo metal bending deformation to consume energy, which greatly improves the energy consumption effect.

[0075] The quantity and specifications of the outer sleeve 3 and the inner core rod 4 are not limited here and can be determined according to actual needs.

[0076] Taking the illustrated scheme as an example, this example uses 3 outer sleeves 3 and 3 inner core rods 4 respectively. These 3 outer sleeves 3 and 3 inner core rods 4 are assembled and matched in sequence to form a three-level energy-consuming module.

[0077] Furthermore, the outer sleeve connecting end 1 and the inner core rod connecting end 2, which serve as the metal energy-consuming support connecting parts, are respectively set at both ends of the multi-stage energy-consuming module for connection with the main structure to be supported.

[0078] Here, the outer sleeve connecting end 1 is detachably screwed to the outer sleeve at one end of the multi-stage energy consumption module, while it is not connected to the nearest inner core rod 4 in the multi-stage energy consumption module, leaving a certain gap 5 between the two; furthermore, the inner core rod connecting end 2 is detachably screwed to the inner core rod 4 at the other end of the multi-stage energy consumption module, while leaving a certain gap 6 between it and the nearest outer sleeve 3 at that end. The gaps 5 and 6 cooperate to form a reserved space to support compression deformation.

[0079] It should be noted that the metal energy-dissipating support given in this example is formed by assembling multiple energy-dissipating modules together. However, actual applications are not limited to this. If necessary, only one set of energy-dissipating modules can be used. The corresponding energy-dissipating modules can be freely selected and flexibly combined from a series of standard modular components to achieve flexible adjustment of support size and energy dissipation parameters, adapting to various application scenarios and installation locations.

[0080] See Figure 3 In this example, the outer sleeve 3 is a hollow cylindrical shape, specifically composed of a metal sleeve 31 and a spiral track 32.

[0081] Specifically, one end of the metal sleeve 31 is provided with an outer thread 33 and the other end is provided with an inner thread 34, for detachable connection combination between multiple outer sleeves (3).

[0082] Based on this, a spiral guide rail 32 with a threaded distribution is provided on the inner wall of the metal sleeve 31 as an energy-consuming limiting component, which is used to cooperate with the spiral metal energy-consuming plate 42 on the inner core rod 4 to form a limiting interference.

[0083] The spiral guide rail 32 starts from one end of the metal sleeve 31 and is distributed in a spiral structure on the inner wall of the metal sleeve 31 along the extension direction of the metal sleeve 31.

[0084] See further Figure 5 In some embodiments, in order to improve the limiting interference fit between the spiral guide rail 32 and the spiral metal energy-consuming plate 42 on the inner core rod 4, and at the same time ensure the ease of assembly between the inner core rod 4 and the metal sleeve 31, the spiral guide rail 32 preferably adopts a "T-groove" structure in cross-section. This facilitates the spiral insertion of the spiral metal energy-consuming plate 42 on the inner core rod 4, prevents the spiral metal energy-consuming plate 42 from detaching from the spiral guide rail 32, and ensures the reliability of the fit during limiting interference.

[0085] It should be noted that the specific structural form of the spiral guide rail 32 is not limited to the "T-slot" structure mentioned above. Other structural forms can also be adopted as needed, as long as the stable and reliable cooperation between the spiral guide rail 32 and the spiral metal energy-consuming plate 42 on the inner core rod 4 is guaranteed.

[0086] See Figures 2a-2b Multiple metal sleeves 31 with such a structure can be effectively connected by their outer threads 33 and inner threads 34 on adjacent metal sleeves 31. For example, the outer thread of the middle metal sleeve is connected to the inner thread of the next metal sleeve, and the inner thread of the middle metal sleeve is connected to the outer thread of the previous metal sleeve, thereby connecting multiple metal sleeves in sequence to form a whole.

[0087] See Figures 4a-4b In this example, the inner core rod 4 is specifically composed of a metal core rod 41 and a spiral metal energy-consuming plate 42.

[0088] Specifically, the metal core rod 41 is a long rod in shape, with a screw 43 with an outward protrusion and a threaded hole 44 at one end and a concave threaded hole 44 at the other end. The screw 43 and the corresponding threaded hole 44 cooperate with each other to realize a detachable connection combination between multiple metal core rods 41.

[0089] Referring to Figure 1-c, the metal core rods 41 with this structure can be effectively connected by screws 43 on them to the threaded holes 44 on the adjacent metal core rods 41. For example, the screw of the middle metal core rod is connected to the threaded hole of the previous metal core rod, and the threaded hole of the middle metal core rod is connected to the screw of the next metal core rod, thereby connecting multiple metal core rods in sequence to form a whole.

[0090] Based on the above structure, the metal core rod 41 has a corresponding spiral metal energy dissipation plate 42 on its outer side wall as an energy dissipation component for bending deformation. It is used to cooperate with the spiral guide rail 32 on the inner wall of the metal sleeve 31 and can bend and deform under the limiting interference of the spiral guide rail 32 to dissipate the energy received by the support.

[0091] The spiral metal energy-consuming plate 42 is radially distributed perpendicularly to the metal core rod 4, and is distributed in a spiral structure on the outer wall of the metal core rod 4 along the extension direction of the metal core rod 4 in the axial direction.

[0092] See further Figure 5 In some embodiments, in order to improve the limiting interference fit between the spiral metal energy-consuming plate 42 on the inner core rod 4 and the spiral guide rail 32 on the inner wall of the metal sleeve 31, and at the same time ensure the ease of assembly between the inner core rod 4 and the metal sleeve 31, the outer end of the spiral metal energy-consuming plate 42 adopts a "T"-shaped cross-section. This "T"-shaped structure is compatible with the spiral guide rail 32 with a "T-groove" structure. This facilitates the spiral insertion of the spiral metal energy-consuming plate 42 on the inner core rod 4, ensuring that the outer end of the spiral metal energy-consuming plate 42 on the inner core rod 4 is always locked in the spiral guide rail 32, preventing the spiral metal energy-consuming plate 42 from disengaging from the spiral guide rail 32, and ensuring the reliability of the fit during limiting interference.

[0093] It should be noted that the specific structural form of the spiral metal energy-consuming plate 42 is not limited to the "T"-shaped structure mentioned above. Other structural forms can also be adopted as needed, as long as the stable and reliable fit between the spiral plate 42 and the spiral guide rail 32 on the inner wall of the metal sleeve 31 is guaranteed.

[0094] The size and pitch of the spiral metal energy-consuming plate 42 on the inner core rod 4 formed by the above scheme can be adjusted according to actual needs. At the same time, based on the spiral distribution structure of the spiral metal energy-consuming plate 42 around the outer side of the metal core rod 41, the energy-consuming plates formed by each ring are in parallel relationship. Under the same support deformation, the energy consumption of each ring of energy-consuming plates is superimposed, thereby greatly improving the energy consumption density.

[0095] In this example, when the inner core rod 4 is combined with the outer sleeve 3, the spiral metal energy-consuming plate 42, which is spirally distributed on the outside of the metal core rod 41, cooperates with the spiral guide rail 32 on the inner wall of the outer sleeve 3, so that the inner core rod 4 is rotated into the outer sleeve 3. At the same time, the spiral distribution on the inner core rod 4 is synchronously rotated into the spiral guide rail 32 on the inner wall of the outer sleeve 3, thereby realizing the combined connection between the inner core rod 4 and the outer sleeve 3.

[0096] See details Figure 5 The outer end of the spiral metal energy-consuming plate 42 on the inner core rod 4 is screwed into the inlet of the spiral guide rail 32 on the inner wall of the outer sleeve 3. The T-shaped end of the spiral metal energy-consuming plate 42 is inserted into the spiral guide rail 32 with the "T-groove" structure. Then, the spiral metal energy-consuming plate 42 is rotated along the spiral guide rail 32 to screw the inner core rod 4 into the inner sleeve 3. The diameter, pitch and total length of the spiral metal energy-consuming plate 42 and the spiral guide rail 32 are matched. The spiral guide rail 32 can firmly hold the end of the spiral metal energy-consuming plate 42 to ensure the effective connection between the spiral metal energy-consuming plate 42 and the metal sleeve 31.

[0097] When a single inner core rod 4 and outer sleeve 3 are combined and connected, they form an energy-consuming module unit. In practical applications, multiple energy-consuming modules can be selected to increase the overall length of the metal energy-consuming support, depending on the specific application scenario and installation location, which can also improve the energy consumption density.

[0098] See Figure 2a In this example, the outer sleeve connection end 1 is used to connect with the outer sleeve 3 and to connect with the main structure to be supported.

[0099] Specifically, the outer sleeve connecting end 1 includes a connecting sleeve 11 and a connecting member 12 disposed on the connecting sleeve.

[0100] The connecting cylinder 11 here is an open-end, hollow cylindrical structure with an internal thread 13 at its end. This internal thread 13 is compatible with the external thread 34 on the outer sleeve 3, allowing for a screw connection between the two. The connector 12 is located at one end of the connecting cylinder 11 and is used to connect to the main structure to be supported. The specific structure of the connector is not limited here.

[0101] The connecting cylinder 11 with this structure can be adjusted and screwed to the end of the outer sleeve 3 with the outer thread 34, and a certain gap 5 is left between it and the inner core rod 4 located inside the outer sleeve 3, as shown in Figure 1-c.

[0102] See further Figure 2a In this example, the inner core rod connecting end 2 is used to connect with the outer sleeve 3 and with the main structure to be supported.

[0103] Specifically, the inner core rod connecting end 2 includes a base 21, a connecting screw 22 disposed at one end of the base 21, and a connecting piece 23 disposed at the other end of the base 21.

[0104] The base 21 here constitutes the main body of the inner core rod connecting end 2. The specific structural form is not limited and can be determined according to actual needs. As an example, the base 21 is a disc structure corresponding to the port of the outer sleeve 3.

[0105] A connecting screw 22 is vertically positioned at the center of one end of the base 21. This connecting screw 22 is adapted to the recessed threaded hole 44 on the inner core rod 4, enabling a screwed connection between the two. A connector 23 is positioned at the center of the other end of the base 21 and is used to connect to the main structure to be supported. The specific structure of the connector is not limited here.

[0106] The inner core rod connecting end 2 with this structure can be inserted into the end of the outer sleeve 3 with the inner thread 34 through the connecting screw 22 on it, and be adjusted and screwed into the concave threaded hole 44 on the inner core rod 4 located in the outer sleeve 3, and a certain gap 6 is left between it and the port of the outer sleeve 3, as shown in Figure 1-c.

[0107] In this example, the outer sleeve connecting end 1 and the inner core rod connecting end 2 of the above structure are connected to the two ends of the energy-consuming module formed by the combination of the inner core rod 4 and the outer sleeve 3 in an adjustable screw connection. This allows the metal energy-consuming component to have an installation error tolerance mechanism. During installation, the support length can be finely adjusted by rotating the corresponding connecting end, so as to achieve smooth installation under certain dimensional deviations.

[0108] In practical applications, the metal energy-dissipating support constructed in this example can be designed with a series of standard modular components for the inner core rod 4 and the outer sleeve 3. These components have different sizes and parameters. At the same time, the spiral metal energy-dissipating pieces on the inner core rod 4 can have different thicknesses and pitches, and can be produced in a standardized manner.

[0109] Meanwhile, as a preferred option, the spiral metal energy dissipation plate 42 in this support uses low yield point steel, high damping alloy or shape memory alloy, while the other components use ordinary steel. This ensures that the formed metal energy dissipation support has sufficient strength and high energy dissipation density.

[0110] See Figures 1a-2b In this example, when assembling the metal energy-dissipating support, all the inner core rods 4 with spiral metal energy-dissipating plates can be connected together to form a combined full-length inner core rod 4, and all the outer sleeves 3 can be connected together to form a combined full-length outer sleeve 3. Then, the full-length inner core rod 4 can be screwed into the full-length outer sleeve 3 to form a combined energy-dissipating module.

[0111] If needed, a single inner core rod 4 can be screwed into a single outer sleeve 3 to form a single energy-consuming module, and then the energy-consuming modules can be connected together again to form a combined energy-consuming module.

[0112] For the formed combined energy-consuming module, the outer sleeve connecting end 1 is screwed to the end of the combined energy-consuming module with the outer thread 33, and a certain gap 5 is left between it and the nearest inner core rod 4 inside the combined energy-consuming module; at the same time, the inner core rod connecting end 2 is inserted into the end of the combined energy-consuming module with the inner thread 34 through the connecting screw 22, and is adjusted and screwed to the concave threaded hole 44 on the nearest inner core rod 4 inside the combined energy-consuming module, and a certain gap 6 is left between it and the nearest outer sleeve 3 as a reserved space for supporting compression deformation. In this way, the assembly of the metal energy-consuming support is completed.

[0113] The assembled metal energy-dissipating support is installed between the main structure to be supported through the connectors at both ends. During installation, the support length can be finely adjusted by rotating the outer sleeve connecting end 1 and the inner core rod connecting end 2 with the energy-dissipating module to ensure smooth installation under certain dimensional deviations.

[0114] With such a metal energy dissipation support, regardless of whether the support as a whole undergoes tensile or compressive deformation, the metal sleeve 31 and the metal core rod 41 move in opposite directions. Based on the mutual limiting interference between the spiral metal energy dissipation plate 42 on the metal core rod 41 and the spiral guide rail 32 on the inner wall of the metal sleeve 31, the spiral metal energy dissipation plate 42 will bend and deform, thus dissipating seismic energy.

[0115] Specifically, this metal energy-dissipating support is installed in the structure, such as at the inter-story level or at the base of a shear wall. Due to structural deformation response, it undergoes tensile or compressive deformation, which in turn causes the metal sleeve 31 and the metal core rod 41 to move in opposite directions. The spiral metal energy-dissipating plate 42 is considered to be a spiral-shaped strip of energy-dissipating plate located between the metal sleeve 31 and the metal core rod 41.

[0116] The spiral metal energy dissipation plate 42 and the metal sleeve 31 are effectively connected, and the spiral metal energy dissipation plate 42 and the metal core rod 41 are also effectively connected. It can be considered that there are effective fixed ends with bending deformation at both ends of the spiral metal energy dissipation plate 42. Under the reverse movement of the metal sleeve 31 and the metal core rod 41, the spiral metal energy dissipation plate 42 can be driven to undergo out-of-plane bending deformation. Under the reciprocating action, the seismic energy is dissipated due to the hysteresis effect of the metal entering the plastic state.

[0117] Furthermore, since the spiral metal energy-consuming plates 42 are spirally distributed, their total length can be adjusted by adjusting the pitch; the greater the total length, the greater the energy consumption density. Simultaneously, during product design, the energy consumption performance parameters of the spiral metal energy-consuming plates 42 can be adjusted by modifying their material, thickness, and width.

[0118] The metal energy dissipation support presented in this example dissipates seismic energy by converting the tensile and compressive deformation of the metal into bending deformation through a spiral metal energy dissipation plate placed between the inner core rod and the outer sleeve. The size and pitch of the spiral metal energy dissipation plate are adjustable, and the superposition of energy dissipation between the energy dissipation plates greatly increases the energy dissipation density. At the same time, the use of energy dissipation support saves on the building materials used in connecting the device to the main structure.

[0119] The metal energy-dissipating support scheme presented in this example has the following technical characteristics compared to existing schemes when adapting to different situations:

[0120] 1. In existing technologies, if the bending deformation of metal is to dissipate seismic energy, it is generally necessary to install it through A-frame bracing or concrete column piers, which consumes a large amount of steel and concrete. This metal energy dissipation support scheme adopts the form of energy dissipation support, giving full play to the advantages of support-type energy dissipation devices in terms of installation, saving the building material consumption for connecting the device with the main structure, and improving installation efficiency.

[0121] 2. Existing metal energy dissipation braces are mainly buckling-restrained braces, which rely on the tensile and compressive deformation of the metal to dissipate seismic energy. This metal energy dissipation brace scheme utilizes the bending deformation of the metal to dissipate seismic energy, changing the way energy dissipation braces mainly rely on the tensile and compressive deformation of the metal to dissipate seismic energy. By setting a spiral metal energy dissipation plate between the core rod and the sleeve, the tensile and compressive deformation of the metal is converted into the bending deformation of the metal to dissipate seismic energy. The size and pitch of the spiral metal energy dissipation plate are adjustable. The energy dissipation plates of each coil are connected in parallel. Under the same support deformation, the energy dissipation of each coil of energy dissipation plate is superimposed, and the energy dissipation density can be greatly improved.

[0122] 3. Existing metal dampers and buckling restraint braces require separate analysis, design, and fabrication, increasing R&D costs and limiting processing efficiency. This metal energy dissipation brace solution adopts standardized production and modular assembly. The core rod and sleeve can be divided into a series of standard modular components with different dimensions and parameters. In particular, the spiral metal energy dissipation plates have different thicknesses and pitches, enabling standardized production. In practical applications, the support size and energy dissipation parameters can be flexibly adjusted through the flexible combination of components of different specifications, adapting to various application scenarios and installation locations.

[0123] 4. This metal energy dissipation support solution adopts a modular prefabricated design: the core rod, sleeve and connecting end are all prefabricated, which can process, transport, hoist and install the ultra-long support in sections, greatly reducing the difficulty of each link and saving costs and time; at the same time, it has an installation error tolerance mechanism, which can realize the fine adjustment of the support length during installation and adapt to the smooth installation under certain dimensional deviations.

[0124] The following examples illustrate the working process of this invention in a specific application. It should be noted that the content described here is only a specific application example of this solution and does not constitute a limitation on this solution.

[0125] Application Example 1:

[0126] In this application embodiment, the inner core rod 4 and the outer sleeve 3 can be divided into a series of standard modular components. Components with different specifications and parameters can be flexibly combined to achieve different support dimensions and energy dissipation parameters to meet the needs of building structure vibration reduction design.

[0127] See Figure 6 Metal energy-dissipating braces are installed in the beam-column joints of the frame structure, using diagonal bracing or herringbone arrangement, and connected to the main structure with bolts.

[0128] Under seismic loading, the inter-story displacement response of the structure is large, which causes the support to undergo tensile and compressive cyclic deformation. Regardless of whether the support undergoes tensile or compressive deformation, the metal sleeve 31 and the metal core rod 41 move in opposite directions, causing the spiral metal energy-dissipating plate 42 to bend and dissipate seismic energy.

[0129] Example 2:

[0130] In this application embodiment, the inner core rod 4 and the outer sleeve 3 can be divided into a series of standard modular components. Components with different specifications and parameters can be flexibly combined to achieve different support dimensions and energy dissipation parameters to meet the needs of building structure vibration reduction design.

[0131] See Figure 7 This support is installed at the column base of the shear wall as a replaceable energy dissipation trench component.

[0132] Under earthquake action, the seismic energy is dissipated by the concentrated plastic deformation of the metal energy-dissipating supports at the base of the wall, protecting the rest of the shear wall. The use of the structure is not affected after the earthquake, and the structure can be fully restored to normal function after the components are replaced.
