Description

Technical Field

[0001] This utility model relates to the field of seismic resistance technology for building structures, specifically a prefabricated metal damper. Background Technology

[0002] Earthquake disasters cause enormous loss of life and property to human society. In order to improve the seismic performance of building structures, energy dissipation and vibration reduction technology has been widely used. Metal dampers, as an important energy dissipation and vibration reduction device, have the advantages of superior energy dissipation performance, simple structure, convenient manufacturing, low cost and easy replacement, and play an important role in the seismic resistance of building structures.

[0003] However, existing metal dampers still have some problems in practical applications. For example, some metal dampers are assembled by welding, and the residual stress generated during the welding process will affect the mechanical stability of the damper. In addition, differences in welding processes will also lead to inconsistencies in the performance of the dampers. Furthermore, when energy dissipation components need to be replaced after an earthquake, the welding connection makes the replacement work difficult, time-consuming, and labor-intensive. In some dampers, during the energy dissipation process, the energy dissipation components are prone to out-of-plane instability or buckling, resulting in a decrease in energy dissipation capacity and failure to fully exert the damping effect of the damper, thus failing to meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide an assembled metal damper to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembled metal damper, comprising an energy-dissipating core material, a reinforcing plate, and a connecting assembly, wherein the reinforcing plate is disposed outside the energy-dissipating core material, and the connecting assembly is disposed outside the energy-dissipating core material.

[0006] The connecting assembly comprises a first bolt, a first nut, a first spring washer, a U-shaped connecting plate, a second bolt, a second nut, a second spring washer, a third bolt, a third nut, and a third spring washer. The first bolt is connected to the interior of the energy-consuming core material, the first nut is threaded onto the end of the first bolt, and the first spring washer is fitted onto the surface of the first bolt. The U-shaped connecting plate is disposed on the exterior of the energy-consuming core material. The second bolt is connected to the interior of the U-shaped connecting plate, the second nut is threaded onto the end of the second bolt, and the second spring washer is fitted onto the surface of the second bolt. The third bolt is connected to the interior of the energy-consuming core material, the third nut is threaded onto the end of the third bolt, and the third spring washer is fitted onto the surface of the third bolt.

[0007] Preferably, the reinforcing plate has corner plates integrally formed around its four sides, and the U-shaped connecting plate is slidably installed inside the corner plates. This arrangement allows the reinforcing plate to position the U-shaped connecting plate.

[0008] Preferably, the energy-consuming core material and the U-shaped connecting plate are connected together by a second bolt, a second nut, and a second spring washer. This arrangement allows for quick assembly and disassembly of the energy-consuming core material and the U-shaped connecting plate via the second bolt, the second nut, and the second spring washer.

[0009] Preferably, the U-shaped connecting plate has two energy-consuming core materials symmetrically arranged inside. The two energy-consuming core materials are connected together by a third bolt, a third nut, and a third spring washer. This arrangement allows for quick assembly and disassembly of the two energy-consuming core materials through the third bolt, the third nut, and the third spring washer.

[0010] Preferably, two U-shaped connecting plates are provided, and the two U-shaped connecting plates are symmetrically arranged on both sides of the reinforcing plate. This arrangement facilitates the subsequent installation of multiple energy-dissipating core materials, which can better cope with earthquakes.

[0011] Preferably, the energy-consuming core material and the reinforcing plate are connected together by a first bolt, a first nut, and a first spring washer. This arrangement allows for quick assembly and disassembly of the energy-consuming core material and the reinforcing plate via the first bolt, the first nut, and the first spring washer.

[0012] Preferably, the energy-dissipating core material is a ring structure. Due to the symmetry of the ring structure, it can effectively absorb and dissipate energy in multiple directions. No matter which direction the seismic wave comes from, the ring energy-dissipating core material can deform in the corresponding direction to dissipate energy. Compared with some energy-dissipating structures subjected to force in a single direction, it has a wider range of energy dissipation adaptability and can more comprehensively cope with seismic action in different directions.

Furthermore, if the energy-dissipating core plate is damaged after an earthquake, the metal damper, due to its prefabricated connection method, can be easily replaced with a new annular energy-dissipating core material, enabling the metal damper to quickly return to normal working condition, providing subsequent seismic protection for the building structure, greatly reducing maintenance costs and time, and improving the post-earthquake recoverability of the building structure.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an assembled metal damper, including an energy-dissipating core material 1, a reinforcing plate 2, and a connecting component 3. The reinforcing plate 2 is disposed outside the energy-dissipating core material 1. The energy-dissipating core material 1 is a ring structure. Due to the symmetry of the ring structure, it can effectively absorb and dissipate energy in multiple directions. No matter which direction the seismic wave comes from, the ring energy-dissipating core material 1 can deform in the corresponding direction to dissipate energy. Compared with some energy-dissipating structures subjected to force in a single direction, it has a wider range of energy dissipation adaptability and can more comprehensively cope with seismic action in different directions. The connecting component 3 is disposed outside the energy-dissipating core material 1.

[0021] The connecting assembly 3 consists of a first bolt 301, a first nut 302, a first spring washer 303, a U-shaped connecting plate 304, a second bolt 305, a second nut 306, a second spring washer 307, a third bolt 308, a third nut 309, and a third spring washer 310. The first bolt 301 is connected to the inside of the energy-dissipating core material 1. The first nut 302 is threaded onto the end of the first bolt 301. The first spring washer 303 is sleeved on the surface of the first bolt 301. The energy-dissipating core material 1 and the reinforcing plate 2 are connected by the first bolt 301 and the first nut 302. The first bolt 302 and the first spring washer 303 are connected together. This arrangement allows for quick assembly and disassembly of the energy-dissipating core material 1 and the reinforcing plate 2 via the first bolt 301, the first nut 302, and the first spring washer 303. The U-shaped connecting plate 304 is located on the outside of the energy-dissipating core material 1. The reinforcing plate 2 has corner plates integrally formed around its perimeter. The U-shaped connecting plate 304 is slidably installed inside the corner plates. This arrangement allows the reinforcing plate 2 to position the U-shaped connecting plate 304. The energy-dissipating core material 1 and the U-shaped connecting plate 304 are connected by the second bolt 305, the second nut 306, and the second spring washer. The components 307 are connected together. This setup allows for quick assembly and disassembly of the energy-dissipating core material 1 and the U-shaped connecting plate 304 via the second bolt 305, the second nut 306, and the second spring washer 307. Two U-shaped connecting plates 304 are provided, symmetrically arranged on both sides of the reinforcing plate 2. This arrangement facilitates the subsequent installation of multiple energy-dissipating core materials 1, providing better earthquake resistance. The second bolt 305 is connected to the inside of the U-shaped connecting plate 304, the second nut 306 is threaded onto the end of the second bolt 305, and the second spring washer 307 is sleeved on the first... The surface of the second bolt 305, the third bolt 308 is connected to the inside of the energy-consuming core material 1, the third nut 309 is threaded onto the end of the third bolt 308, the third spring washer 310 is sleeved on the surface of the third bolt 308, and two energy-consuming core materials 1 are symmetrically arranged inside the U-shaped connecting plate 304. The two energy-consuming core materials 1 are connected together by the third bolt 308, the third nut 309 and the third spring washer 310. This arrangement allows for quick assembly and disassembly of the two energy-consuming core materials 1 through the third bolt 308, the third nut 309 and the third spring washer 310.

[0022] In use, the energy-dissipating core material 1 and the U-shaped connecting plate 304 are connected together using the second bolt 305, the second nut 306, and the second spring washer 307. Then, the two energy-dissipating core materials 1 inside the U-shaped connecting plate 304 are connected together using the third bolt 308, the third nut 309, and the third spring washer 310. Two sets of the above components are assembled on both sides of the reinforcing plate 2. Finally, the energy-dissipating core material 1 and the reinforcing plate 2 are connected together using the first bolt 301, the first nut 302, and the first spring washer 303, completing the assembly of the metal damper. Due to the symmetry of the annular structure, the annular energy-dissipating core material 1 can effectively absorb and dissipate energy in multiple directions. Regardless of the direction from which the seismic wave originates, the annular... The energy-dissipating core material 1 can deform in the corresponding direction to dissipate energy. Compared with some energy-dissipating structures subjected to force in a single direction, it has a wider range of energy dissipation adaptability and can more comprehensively cope with seismic forces in different directions. When the seismic force gradually weakens and ends, the annular energy-dissipating core material 1 will not completely return to its original shape due to plastic deformation. However, as long as it is not severely damaged, it can still continue to play a certain energy dissipation role. If the energy-dissipating core material 1 is severely damaged in the earthquake, since the metal damper adopts an assembled connection method, a new annular energy-dissipating core material 1 can be easily replaced, so that the metal damper can quickly return to normal working condition and provide subsequent seismic protection for the building structure.
