Description

Technical Field

[0001] The present invention relates to the technical field of engineering structure vibration dampers, and more particularly to a metal damping vibration absorbing device. Background Art

[0002] Earthquakes are sudden, destructive natural disasters, often associated with sudden ruptures within the Earth's interior. These waves cause ground vibrations within a certain range, making them a common occurrence alongside tsunamis, volcanoes, and typhoons. Earthquakes can cause permanent damage to structures on the ground. With the increasing volume of building construction, the consequences of earthquake damage are immeasurable. Therefore, it is necessary to improve their seismic resistance through engineering and technical measures.

[0003] In recent decades, engineers have developed various engineering technologies to mitigate the damage caused by earthquakes to building structures. Among them, metal dampers are widely favored by engineering designers due to their extremely high cost-effectiveness, better energy dissipation capacity, and the advantage of being replaceable after an earthquake. Building structures with reasonable metal dampers can more effectively dissipate earthquake energy and avoid major damage to the building structure. As a displacement damper, the metal damper is a passive energy dissipation device. Under the action of small earthquakes, the metal damper is in the elastic working stage, which will provide additional stiffness to the structure but will not absorb energy. Under the action of a large earthquake, the metal damper will yield before the main structure undergoes plastic deformation, and then enter the elastic-plastic working stage, consuming the energy input by the earthquake through hysteresis deformation.

[0004] Currently, metal dampers come in a variety of forms. However, the multi-directional coupling of energy dissipation in practical building structures can easily degrade the damper's energy dissipation capacity and make it difficult to simultaneously meet the building's longitudinal and lateral seismic requirements. Therefore, a new vibration-absorbing device capable of achieving bidirectional decoupling of metal dampers is a pressing issue for those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a metal damping and shock absorbing device that can simultaneously meet the lateral and longitudinal shock absorption requirements of building structures. In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] The present invention provides a metal damping and shock absorbing device, comprising:

[0007] a first connecting block, wherein a second connecting block is provided on one side of the first connecting block, the first connecting block and the second connecting block are spaced apart, and ends of the first connecting block and the second connecting block that are away from each other are connected to the building structure;

[0008] The metal damper group includes a transverse metal damper and a longitudinal metal damper, wherein one end of the transverse metal damper is slidably connected to the first connecting block or the second connecting block in the longitudinal direction, and the other end of the transverse metal damper is fixedly connected to the second connecting block or the first connecting block; one end of the longitudinal metal damper is slidably connected to the first connecting block or the second connecting block in the transverse direction, and the other end of the longitudinal metal damper is fixedly connected to the second connecting block or the first connecting block.

[0009] Furthermore, one end of the transverse metal damper is slidably connected to the first connection block in the longitudinal direction, and the other end of the transverse metal damper is fixedly connected to the second connection block.

[0010] Furthermore, one end of the longitudinal metal damper is slidably connected to the second connection block in the transverse direction, and the other end of the longitudinal metal damper is fixedly connected to the first connection block.

[0011] Furthermore, a longitudinal sliding groove is provided at one end of the first connecting block close to the second connecting block, and a slider is provided at one end of the transverse metal damper close to the first connecting block, and the slider is slidably connected to the longitudinal sliding groove.

[0012] Furthermore, a transverse sliding groove is provided at one end of the second connecting block close to the first connecting block, and a slider is provided at one end of the longitudinal metal damper close to the second connecting block, and the slider is slidably connected to the transverse sliding groove.

[0013] Furthermore, two transverse metal dampers are provided, and the two transverse metal dampers are respectively slidably connected to the two transverse ends of the first connecting block.

[0014] Furthermore, two longitudinal metal dampers are provided, and the two longitudinal metal dampers are respectively slidably connected to the two ends of the longitudinal direction of the second connecting block.

[0015] Furthermore, one end of the transverse metal damper away from the first connecting block is connected to the second connecting block through a fixing block, and one end of the longitudinal metal damper away from the second connecting block is connected to the first connecting block through a fixing block.

[0016] Furthermore, the fixing block on the first connecting block is arranged at a middle position in the transverse direction of the first connecting block, and the fixing block on the second connecting block is arranged at a middle position in the longitudinal direction of the second connecting block.

[0017] It can be seen from the above technical solution that compared with the prior art, the present invention discloses a metal damping shock-absorbing device, in which the metal damper group can simultaneously match the longitudinal and lateral seismic resistance requirements of the building structure, improve the longitudinal and lateral seismic resistance of the building structure, and meet the lateral shock-absorbing requirements of the building structure through the lateral metal damper, thereby realizing lateral shock absorption of the building structure. The longitudinal metal damper meets the longitudinal shock-absorbing requirements of the building structure, thereby realizing longitudinal shock absorption of the building structure, so that each displacement damper only needs to deform in a single direction, thereby avoiding the degradation of the energy consumption capacity of the displacement damper due to multi-directional energy consumption, thereby ensuring the stability of the building structure.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-7 , an embodiment of the present invention discloses a metal damping and shock absorbing device, comprising:

[0029] A first connecting block 2, a second connecting block 3 is provided on one side of the first connecting block 2, the first connecting block 2 and the second connecting block 3 are spaced apart, and the ends of the first connecting block 2 and the second connecting block 3 that are away from each other are connected to the building structure;

[0030] The metal damper group includes a transverse metal damper 61 and a longitudinal metal damper 62. One end of the transverse metal damper 61 is slidably connected to the first connecting block 2 or the second connecting block 3 in the longitudinal direction, and the other end of the transverse metal damper 61 is fixedly connected to the second connecting block 3 or the first connecting block 2. One end of the longitudinal metal damper 62 is slidably connected to the first connecting block 2 or the second connecting block 3 in the transverse direction, and the other end of the longitudinal metal damper 62 is fixedly connected to the second connecting block 3 or the first connecting block 2.

[0031] When the building structure undergoes lateral displacement under the action of an earthquake, the lateral metal damper 61 undergoes shear deformation, thereby dissipating the energy of the earthquake motion and ensuring the lateral stability of the building structure. The longitudinal metal damper 62 does not deform and does not consume energy, thereby ensuring the energy dissipation capacity of the longitudinal metal damper 62.

[0032] When the building structure undergoes longitudinal displacement under the action of an earthquake, the longitudinal metal damper 62 undergoes shear deformation, thereby dissipating the energy of the earthquake and ensuring the longitudinal stability of the building structure. The transverse metal damper 61 does not deform and does not consume energy, thereby ensuring the energy dissipation capacity of the transverse metal damper 61.

[0033] In some embodiments, the ends of the first connecting block 2 and the second connecting block 3 that are away from each other are connected to the building structure through the anchor rod 1 .

[0034] In some embodiments, one end of the transverse metal damper 61 is slidably connected to the first connection block 2 in the longitudinal direction, and the other end of the transverse metal damper 61 is fixedly connected to the second connection block 3 .

[0035] When the building structure undergoes lateral displacement under the action of an earthquake, the first connecting block 2 undergoes lateral displacement relative to the second connecting block 3. At this time, one end of the lateral metal damper 61 moves laterally with the first connecting block 2 relative to the second connecting block 3, generating shear deformation, dissipating the energy of the earthquake, and ensuring the lateral seismic resistance of the building structure.

[0036] In some embodiments, one end of the longitudinal metal damper 62 is slidably connected to the second connection block 3 in the transverse direction, and the other end of the longitudinal metal damper 62 is fixedly connected to the first connection block 2 .

[0037] When the building structure undergoes longitudinal displacement under the action of an earthquake, the first connecting block 2 undergoes longitudinal displacement relative to the second connecting block 3. At this time, since one end of the longitudinal metal damper 62 moves longitudinally with the first connecting block 2 relative to the second connecting block 3, shear deformation occurs, dissipating the energy of the earthquake and ensuring the longitudinal seismic resistance of the building structure.

[0038] In some embodiments, a longitudinal sliding groove is provided at one end of the first connecting block 2 close to the second connecting block 3, and a slider 4 is provided at one end of the transverse metal damper 61 close to the first connecting block 2, and the slider 4 is slidably connected to the longitudinal sliding groove.

[0039] In some embodiments, a transverse sliding groove is provided at one end of the second connecting block 3 close to the first connecting block 2, and a slider 4 is provided at one end of the longitudinal metal damper 62 close to the second connecting block 3, and the slider 4 is slidably connected to the transverse sliding groove.

[0040] When the building structure undergoes lateral displacement under the action of an earthquake, the first connecting block 2 undergoes lateral displacement relative to the second connecting block 3. Driven by the first connecting block 2, the longitudinal metal damper 62 slides within the transverse groove 8 of the second connecting block 3 without deformation. At this time, the transverse metal damper 61 cannot produce relative movement with the first connecting block 2. Therefore, the transverse metal damper 61 undergoes shear deformation under the tension of the first connecting block 2 and the second connecting block 3, dissipating the energy of the earthquake, reducing the relative movement between the first connecting block 2 and the second connecting block 3, and ensuring the lateral stability of the building structure.

[0041] When the building structure undergoes longitudinal displacement under the action of an earthquake, the first connecting block 2 undergoes longitudinal displacement relative to the second connecting block 3. At this time, since the transverse metal damper 61 is slidingly connected to the first connecting block 2, the end of the transverse metal damper 61 close to the first connecting block 2 will not move with the first connecting block 2 but will slide in the longitudinal slide groove 7 of the first connecting block 2. Therefore, no deformation will occur. The longitudinal metal damper 62 cannot slide relative to the first connecting block 2 and the second connecting block 3 in the longitudinal direction. Therefore, the two ends of the longitudinal metal damper 62 move longitudinally with the first connecting block 2 and the second connecting block 3 respectively. At this time, the longitudinal metal damper 62 undergoes shear deformation under the action of the tension of the first connecting block 2 and the second connecting block 3, reducing the relative movement between the first connecting block 2 and the second connecting block 3, thereby ensuring the longitudinal stability of the building structure.

[0042] In some embodiments, two transverse metal dampers 61 are provided, and the two transverse metal dampers 61 are respectively slidably connected to the two transverse ends of the first connection block 2 .

[0043] In some embodiments, two longitudinal metal dampers 62 are provided, and the two longitudinal metal dampers 62 are respectively slidably connected to the two ends of the second connecting block 3 in the longitudinal direction.

[0044] In some embodiments, the end of the transverse metal damper 61 away from the first connecting block 2 is connected to the second connecting block 3 through the fixing block 5, and the end of the longitudinal metal damper 62 away from the second connecting block 3 is connected to the first connecting block 2 through the fixing block 5.

[0045] In some embodiments, the end of the transverse metal damper 61 close to the first connecting block 2 is slidingly connected to the longitudinal slide groove 7 through the slider 4, and the end of the longitudinal metal damper 62 close to the second connecting block 3 is slidingly connected to the transverse slide groove 8 through the slider 4.

[0046] In some embodiments, the fixing block 5 on the first connecting block 2 is arranged in the middle position of the first connecting block 2 in the transverse direction, and the fixing block 5 on the second connecting block 3 is arranged in the middle position of the second connecting block 3 in the longitudinal direction.

[0047] When the building structure undergoes lateral displacement under the action of an extreme earthquake, the deformation of the lateral metal damper 61 reaches its maximum value, and the slider 4 slides to the edge of the lateral slot 8. The lateral slot 8 prevents the slider 4 from sliding further, causing the longitudinal metal damper 62 to begin to participate in the force and deform, further dissipating the earthquake energy and protecting the building structure.

[0048] When the building structure undergoes longitudinal displacement under the action of an extreme earthquake, the deformation of the longitudinal metal damper 62 reaches its maximum value, and the slider 4 slides to the edge of the longitudinal slot 7. The longitudinal slot 7 prevents the slider 4 from sliding further longitudinally, causing the transverse metal damper 61 to begin to participate in the force and deform, further dissipating the seismic energy, realizing the graded energy consumption of the metal damping and shock-absorbing device under extreme conditions, and further protecting the building structure.
