Description

Technical Field

[0001] The invention relates to the technical field of earthquake resistance of building structures, and in particular provides a gradient yield type energy dissipation damper which is easy to replace. Background Art

[0002] Metal dampers are a common energy dissipation device widely used in building structures. During an earthquake, dampers dissipate seismic energy in a concentrated manner, reducing damage to key building components and thus improving the building's seismic resistance.

[0003] Conventional metal dampers currently have a fixed yield point and lack gradient yield capacity, effectively limiting their effectiveness against specific earthquakes. For example, buckling-restrained braces, to ensure energy dissipation under large earthquakes, often remain elastic under smaller ones, lacking energy dissipation capacity. Furthermore, conventional metal dampers are prone to damage accumulation under small deformations, impacting their energy dissipation capacity under larger deformations.

[0004] In terms of post-earthquake repairability or replacement, existing metal dampers are often affected by residual deformation during replacement. Excessive residual deformation necessitates cutting or hole enlarging, increasing the difficulty of post-earthquake structural repair. Furthermore, most damper replacements require the complete replacement of both the connecting and energy-consuming components, resulting in material waste. Summary of the Invention

[0025] The following combination Figures 1 to 17 The embodiment shown describes the technical solution of the present invention: The embodiment of the present invention provides a gradient yield type energy dissipation damper that is easy to replace, such as Figures 1 to 3 As shown, it includes: a base plate 1, a support assembly 2, a swing force transmission member 3, a reset assembly 4, a first energy dissipation tube 5 and a second energy dissipation rod 6; Among them, the support assembly 2 is arranged on the base plate 1; the swinging force transmission member 3 is rotatably connected to the support assembly 2, and the rotating shaft of the swinging force transmission member 3 is parallel to the base plate 1, and the swinging force transmission member 3 is used to be connected to the building structure; the reset assembly 4 is arranged on the base plate 1 and connected to the swinging force transmission member 3, and is used to cause the swinging force transmission member 3 to be in the middle position; the first energy-absorbing tube 5 has one end that is detachably and non-rotatably mounted on the support assembly 2, and the other end that is detachably connected to the swinging force transmission member 3, and is coaxially arranged with the rotating shaft of the swinging force transmission member 3; the second energy-absorbing rod 6 has one end that is detachably and non-rotatably mounted on the support assembly 2, and the other end that is detachably connected to the swinging force transmission member 3, and is coaxially arranged with the rotating shaft of the swinging force transmission member 3; The diameter of the first energy-consuming tube 5 is larger than that of the second energy-consuming rod 6 , and the length of the first energy-consuming tube 5 is smaller than that of the second energy-consuming rod 6 .

[0026] In some embodiments, the support assembly 2 can be a semicircular shape, a combination of a regular quadrilateral and an arch, or a regular pentagon, a regular hexagon, etc., as long as it can be fixedly mounted and connected to other parts of the damper; the swing force transmission member 3 can be a rectangular shape, a bar shape, etc., as long as it can transmit the external force applied to the damper to the first energy dissipation tube 5 during the shock absorption process; In this embodiment, Figure 1 As shown, the support assembly 2 is preferably a support plate with a regular quadrilateral cross section, which is fixed to the base plate 1 and is also used to connect and install the remaining damper parts; the swinging force transmission member 3 is preferably a combination shape with a semicircular bottom and the rest of the body being a rectangle, and is rotatably connected to the support assembly 2, and the rotating shaft of the swinging force transmission member 3 is parallel to the base plate 1. The swinging force transmission member 3 is used to be connected to the building structure, and during the shock absorption process, the external force applied to the damper is transmitted to the first energy dissipation tube 5. That is, when the swinging force transmission member 3 is swung by an external force, because it is rotatably connected to the support assembly 2, the swinging force transmission member 3 can swing around the support assembly 2, and at the same time, the rotating shaft of the swinging force transmission member 3 is parallel to the base plate 1, so that the component connected to the rotating shaft of the swinging force transmission member 3 can swing or rotate simultaneously with the swinging force transmission member 3. The reset assembly 4 is provided to offset part of the external force exerted on the swinging force transmission member 3 during the shock absorption process, thereby reducing the external force exerted on the energy-absorbing rod connected to the swinging force transmission member 3 and reducing the deformation of the energy-absorbing rod, which is convenient for replacement of the energy-absorbing rod after the shock absorption is completed; the first energy-absorbing tube 5 is detachably and non-rotatably mounted on the support assembly 2 at one end, and detachably connected to the swinging force transmission member 3 at the other end, and is coaxially arranged with the rotating shaft of the swinging force transmission member 3. During the shock absorption process, when the swinging force transmission member 3 is subjected to external force and swings or rotates, the first energy-absorbing tube 5 coaxially arranged with the swinging force transmission member 3 swings or rotates at the same time, thereby offsetting the external force exerted on the damper and reducing damage to the building structure components; Similarly, the second energy-absorbing rod 6 has one end detachably and non-rotatably mounted on the support assembly 2, and the other end detachably connected to the swinging force transmission member 3 and coaxially arranged with the rotating axis of the swinging force transmission member 3. During the damping process, when the swinging force transmission member 3 is subjected to an external force and swings or rotates, the second energy-absorbing rod 6 coaxially arranged with the swinging force transmission member 3 swings or rotates simultaneously, thereby offsetting the external force applied to the damper and reducing damage to the building structure components. And since one end of the first energy-absorbing tube 5 and the second energy-absorbing rod 6 are both detachably and non-rotatably mounted on the support assembly 2, and the other end is detachably connected to the swinging force transmission member 3, when a certain energy-absorbing material needs to be replaced, the locking nut at the connection between the energy-absorbing material and the support assembly 2 and the swinging force transmission member 3 can be twisted to remove the certain energy-absorbing material and replace it with a new energy-absorbing material.

[0027] The diameter of the first energy dissipation tube 5 is greater than that of the second energy dissipation rod 6, and the length of the first energy dissipation tube 5 is less than that of the second energy dissipation rod 6, so that the first energy dissipation tube 5 has a stronger shock absorption capacity than the second energy dissipation rod 6. Within an appropriate range, the first energy dissipation tube 5 can offset the external force applied to the damper, or when the first energy dissipation tube 5 fails, the second energy dissipation rod 6 can still play an energy dissipation effect to ensure the normal operation of the damper; at the same time, the first energy dissipation tube 5 and the second energy dissipation rod 6 are both detachably non-rotatably mounted on the support assembly 2 at one end, and detachably connected to the swinging force transmission member 3 at the other end. After receiving the rotational force transmitted from the swinging force transmission member 3, rotational friction is generated between the connection end of the first energy dissipation tube 5 and the support assembly 2 to offset the external force applied thereto, thereby reducing damage to the building structure components.

[0028] The present invention provides an easily replaceable gradient-yield energy-dissipating damper. By improving the traditional metal damper into an energy-dissipating damper with a gradient-yield structure, it effectively solves the problem of the prior art metal dampers not having gradient-yield capability. At the same time, through the detachable connection of the consumable part, only the consumable part can be replaced without removing the entire damper, effectively improving the replacement efficiency of the consumables and the utilization rate of the remaining non-consumable parts. Specifically: By arranging first energy-absorbing tubes 5 and second energy-absorbing rods 6 of different sizes on the support assembly 2, wherein one end of the first energy-absorbing tube 5 is detachably mounted on the support assembly 2, and the other end is detachably connected to the swinging force transmission member 3 and is coaxially arranged with the rotating shaft of the swinging force transmission member 3; in this way, the first energy-absorbing tube 5 can be twisted when the vibration of the building structure is small, and the first energy-absorbing tube 5 can also be easily replaced separately; One end of the second energy-absorbing rod 6 is detachably and non-rotatably mounted on the support assembly 2, and the other end is detachably connected to the swinging force transmission member 3 and is coaxially arranged with the rotation axis of the swinging force transmission member 3. In this way, the second energy-absorbing rod 6 can be twisted when the building structure vibrates greatly, and the second energy-absorbing rod 6 can also be easily replaced separately. In this way, the multi-gradient yield of the damper is achieved, avoiding the problem of poor adaptability of traditional dampers due to the fixed yield point.

[0029] By providing the reset component 4 , the damping effect of the damper can be enhanced.

[0030] According to the energy dissipation damper provided by the embodiment of the present invention, Figures 4 to 7 As shown, the reset component 4 includes: There are at least two elastic members 401, which are respectively provided on both sides of the swing force transmission member 3 and hinged to the bottom plate 1; There are at least two connecting parts 402, which are respectively arranged on both sides of the swinging force transmission part 3. One end of each connecting part is hinged to the swinging force transmission part 3, and the other end is connected to the elastic part 401, and is used to stretch and squeeze the elastic part 401 when the swinging force transmission part 3 swings.

[0031] In this embodiment, Figure 4 The reset assembly 4 shown includes an elastic member 401 and a linking member 402, and the elastic member 401 and the linking member 402 have at least two, such as Figure 7 As shown, the elastic member 401 is hinged to the bottom plate 1, one end of the linking member 402 is hinged to the swing force transmission member 3, and the other end is connected to the elastic member 401. During the shock absorption process, the swing force transmission member 3 is subjected to external force. Under the action of the external force, the swing force transmission member 3 drives the linking member 402 of the reset assembly 4 on one side to move upward. Figure 5 As shown, the corresponding linking member 402 of the reset assembly 4 on the other side is pressed down as shown Figure 6 As shown, at this time, when the corresponding linking member 402 is in the upward moving state, the elastic member 401 will cause it to have a tendency to move downward, and when the corresponding linking member 402 is in the downward pressing state, the elastic member 401 will cause it to have a tendency to move upward, balancing the external forces exerted on each other, so that the reset component 4 can offset part of the external force exerted on the swinging force transmission member 3; the reset component 4 can offset part of the external force exerted on the swinging force transmission member 3, thereby increasing the bearing capacity of the damper, and at the same time promotes the reset of the swinging force transmission member 3, which is beneficial to the replacement of the first energy dissipation tube 5 and the second energy dissipation rod 6.

[0032] According to the energy dissipation damper provided by the embodiment of the present invention, Figures 7 to 9 As shown, the elastic member 401 includes: Sliding rod 4011, vertically fixed to bottom plate 1; There are at least two pressing plates 4012, which are sleeved on the sliding rod 4011; The spring 4013 is sleeved on the slide bar 4011 and is located between the pressure plates 4012; There are at least two limiting members 4014 fixed to the slide bar 4011 and respectively disposed on opposite sides of the pressing plate 4012; The pressing plate 4012 is connected to the linking member 402 .

[0033] In some embodiments, the spring 4013 can be a metal spring, a disc spring, a composite material spring, etc., which can provide an opposite force to the linkage 402; In this embodiment, the spring 4013 is preferably a disc spring, and the sliding rod 4011 in the elastic member 401 is vertically hinged to the base plate 1, and the sliding rod 4011 provides a sliding attachment for the extension or compression of the spring 4013; the pressure plate 4012 is in contact with the connecting member 402, providing a force point for the deformation of the spring 4013; the limit member 4014 constrains the movement of the pressure plate 4012, thereby limiting the maximum deformation range of the spring 4013; therefore, the elastic member 401 provides resistance for the reset component 4 to offset external forces during the shock absorption process.

[0034] According to the energy dissipation damper provided in the embodiment of the present invention, Figure 1 、 Figure 10 and Figure 11 As shown, the linkage 402 includes: A U-shaped cover 4021 is provided on the elastic member 401; The ear plate 4022 is fixed to the upper end surface of the U-shaped cover 4021 and is hinged to the swing force transmission member 3; At least two baffles 4023 are fixed to the upper and lower portions of the inner wall of the U-shaped cover 4021, respectively, and are spaced apart from the pressure plate 4012 in the axial direction of the slide bar 4011. The baffles 4023 also extend in the radial direction of the slide bar 4011 and are partially overlapped with the pressure plate 4012. The two pressing plates 4012 are located between the two sets of baffles 4023 .

[0035] In this embodiment, the ear plate 4022 is fixed to the upper end surface of the U-shaped cover 4021 and is hinged to the swinging force transmission member 3. During the shock absorption process, when the swinging force transmission member 3 is swung or rotated by external force, the ear plate 4022 is hinged to it, so the swinging force transmission member 3 can drive the U-shaped cover 4021 to swing or rotate; the baffle 4023 has at least two groups, which are respectively fixed to the upper and lower parts of the inner wall of the U-shaped cover 4021, and the width of the baffle 4023 in the axial direction of the slide rod 4011 enables it to overlap with the pressure plate 4012. When the swinging force transmission member 3 drives the U-shaped cover 4021 to swing or rotate, the baffle 4023 constrains its swing amplitude. Through the mutual constraint between the baffle 4023 and the pressure plate 4012, the reset assembly 4 can offset part of the external force from the swinging force transmission member 3 during the shock absorption process, reduce the external force on the swinging force transmission member 3, increase the bearing capacity of the damper, and extend the service life of the swinging force transmission member 3.

[0036] According to the energy dissipation damper provided in the embodiment of the present invention, Figure 1 、 Figure 11 and Figure 12 As shown, the swing force transmission member 3 includes: The main body 301 is rotatably connected to the support assembly 2; Extension portions 302 extending in opposite directions along both sides of the main body portion 301; The structural force transmission portion 303 is connected to the main body 301 and is used to transmit the vibration force of the building structure to the main body 301 .

[0037] In some embodiments, the main body 301 may be a square plate with a connection hole at the bottom, etc., so as to be connected to the support assembly 2; the structural force transmission portion 303 may be a circular column, a square column, etc., directly fixed to the surface of the main body 301, etc., so as to be connected to the main body of the building structure; In this embodiment, the main body 301 is rotatably connected to the support assembly 2. During the shock absorption process, when subjected to external force, the main body 301 can swing or rotate around the support assembly 2, and transmit the external force to the first energy-absorbing tube 5 and the second energy-absorbing rod 6 connected to the support assembly 2; the extension part 302 transmits the external force to the connecting part 402 hinged to it, so that the reset assembly 4 can simultaneously offset part of the external force exerted on the swinging force transmission part 3, reduce the external force exerted on the first energy-absorbing tube 5 and the second energy-absorbing rod 6, and increase the service life of the first energy-absorbing tube 5 and the second energy-absorbing rod 6; the structural force transmission part 303 is connected to the main body 301 and to the building structure, and transmits the vibration external force exerted on the building structure to the main body 301.

[0038] According to the energy dissipation damper provided in the embodiment of the present invention, Figure 1 and Figure 13 As shown, the main body 301 includes a plate 3011 , and a slot 30111 is formed on the plate 3011 ; The extension portion 302 includes at least two extension arms 3021 , and the extension arms 3021 are respectively fixed to two sides of the plate 3011 ; The structural force transmission portion 303 includes a force transmission rod 3031 , one end of which passes through the slot 30111 .

[0039] In this embodiment, the main body 301 is preferably a plate 3011, and a slot 30111 is provided on the plate 3011. The structural force transmission part 303 is preferably a force transmission rod 3031, and one end of the force transmission rod 3031 passes through the slot 30111. Compared with the structure directly fixed to the main body 301, the structure of the swinging force transmission member 3 in this embodiment can effectively transmit the external force exerted on the damper without the connection between the structural force transmission part 303 and the main body 301 being broken, resulting in the external force acting directly on the energy-absorbing rod, causing damage to the energy-absorbing rod or the damper itself, resulting in serious damage to the building.

[0040] According to the energy dissipation damper provided in the embodiment of the present invention, Figure 1 、 Figure 14 and Figure 15 As shown, the support assembly 2 includes: The first support plate 201 is fixed to the bottom plate 1 and has a first mounting hole 202; The second support plate 203 is fixed to the bottom plate 1 and is arranged parallel to the first support plate 201. The second mounting hole 204 is formed. The inner wall of the second mounting hole 204 is formed with a first anti-rotation groove 205. One end of the first energy dissipation tube 5 is detachably connected to the first support plate 201, and the other end is detachably connected to the swing force transmission member 3; One end of the second energy-absorbing rod 6 has a first anti-rotation edge 206 and is arranged in the first mounting hole 202. The first anti-rotation edge 206 cooperates with the first anti-rotation groove 205. The other end of the second energy-absorbing rod 6 passes through the first energy-absorbing tube 5 and is detachably connected to the swinging force transmission member 3.

[0041] In this embodiment, the second mounting hole 204 formed on the second support plate 203, the first anti-rotation groove 205 formed on the inner wall thereof, and the first anti-rotation edge 206 on one end of the second energy-absorbing rod 6 together constitute an anti-rotation assembly, wherein: The first support plate 201 is fixed to the base plate 1 and is provided with a first mounting hole 202, so that the first energy-absorbing tube 5 can be detachably mounted between the first support plate 201 and the swinging force-transmitting member 3. During the shock absorption process, the external force exerted on the swinging force-transmitting member can act on the first energy-absorbing tube 5, thereby protecting the building structure through the damper; at the same time, a second mounting hole 204 is provided on the second support plate 203, and a first anti-rotation groove 205 is provided on the inner wall of the second mounting hole 204. One end of the second energy-absorbing rod 6 has a first anti-rotation edge 206 that matches the first anti-rotation groove 205, and the other end passes through the first The energy-absorbing tube 5 and the external force transmitted by the swinging force transmission member 3 cause the first anti-rotation groove 205 and the first anti-rotation edge 206 to stop rotating with each other, thereby improving the bearing capacity of the first energy-absorbing tube 5 and the second energy-absorbing rod 6. At the same time, one end of the second energy-absorbing rod 6 is arranged at the connection between the swinging force transmission member 3 and the first energy-absorbing tube 5, so that when the first energy-absorbing tube 5 reaches its bearing limit, the second energy-absorbing rod 6 can replace it to achieve the shock-absorbing effect, ensuring the protective effect of the damper on the building structure while preventing the deformation of the first energy-absorbing tube 5 and the second energy-absorbing rod 6 from being too large, so that they can be disassembled and replaced later.

[0042] According to the energy dissipation damper provided by the embodiment of the present invention, Figure 1 and Figure 16 As shown, it also includes a third support plate 207, which is fixed to the bottom plate 1 and arranged parallel to the second support plate 203, and the third support plate 207 is provided with a third mounting hole 208; The swing force transmission member 3 includes a transmission circular plate 304, which is coaxially and detachably mounted on the rotating shaft of the swing force transmission member 3 and rotatably mounted in the third mounting hole 208; The transmission circular plate 304 is coaxially provided with a fourth mounting hole 3041 , and a second anti-rotation groove 30411 is provided in the fourth mounting hole 3041 ; The other end of the second energy-absorbing rod 6 has a second anti-rotation edge 601 , which is disposed in the fourth mounting hole 3041 . The second anti-rotation edge 601 cooperates with the second anti-rotation groove 30411 .

[0043] In this embodiment, the swinging force transmission member 3 includes a transmission circular plate 304 that is detachably mounted on the rotating shaft of the swinging force transmission member 3 and rotatably mounted within the third mounting hole 208 of the third support plate 207. The transmission circular plate 304 is coaxially defined with a fourth mounting hole 3041, within which a second anti-rotation groove 30411 is defined. The other end of the second energy dissipation rod 6 has a second anti-rotation edge 601 disposed in the fourth mounting hole 3041, with the second anti-rotation edge 601 engaging with the second anti-rotation groove 30411. The transmission circular plate 304 transmits the swinging force transmission member 3 subjected to external forces to the second energy dissipation rod 6 and the first energy dissipation tube 5. Simultaneously, the rotational friction between the second anti-rotation edge 601 on the other end of the second energy dissipation rod 6 and the second anti-rotation groove 30411 partially offsets the external forces transmitted by the swinging force transmission member 3, reducing losses in the second energy dissipation rod 6 and ensuring that the damper has a good shock absorption effect.

[0044] According to the energy dissipation damper provided in the embodiment of the present invention, Figure 17 As shown, the damper is installed on the building steel frame 7 through the base plate 1 and is connected to the building steel frame 7 through the force transmission rod 3031. The vibration of the building steel frame 7 is transmitted to the damper through the force transmission rod 3031, and the damper reduces the seismic response of the building steel frame 7 during the earthquake, thereby reducing the damage to the building steel frame 7.
