Description

Technical Field

[0001] The invention relates to a bending parallel dog bone hole soft steel plate laminated rubber energy dissipation and shock absorption device for a steel frame-support structure and a manufacturing method thereof, belonging to the technical field of building shock absorption. Background Art

[0002] Improving the seismic performance of buildings is the key to solving the problem of building damage and collapse under strong earthquakes. Three technologies are usually used: the first is seismic design technology, that is, using efficient seismic structural systems and high-performance seismic components to improve the seismic resistance of the structure; the second is seismic isolation design technology, that is, using basic seismic isolation devices to reduce the effect of earthquakes on the upper structure; the third is energy dissipation and shock reduction technology, that is, using energy dissipation and shock reduction devices to consume the energy input into the structure by the earthquake and reduce structural damage. If the weak energy dissipation and shock reduction device is damaged under strong earthquakes, it can be updated. Building seismic isolation and shock reduction technology can be applied in combination.

[0003] The engineering community at home and abroad has always attached great importance to the research and development of new energy dissipation and shock absorption devices. At present, energy dissipation and shock absorption devices mainly include viscous dampers, metal dampers, friction dampers, etc. However, there is a lack of functional and easily recoverable energy dissipation and shock absorption devices and manufacturing technologies suitable for performance-based design and with multiple anti-seismic lines.

[0004] The present invention proposes a rubber energy dissipation and shock absorption device and method for a steel frame-support structure with parallel dog-bone holes, which belongs to the technical field of building shock absorption. The device is composed of an upper connecting steel plate with circular holes connected to the lower flange of the H-beam of the steel frame, a lower connecting steel plate connected to the end plate welded to the intersection area of ​​the H-shaped support, left and right side sealing skin dog-bone holes soft steel plates welded between the upper and lower connecting steel plates, parallel dog-bone holes soft steel plates welded between the upper and lower connecting steel plates, front and rear sealing soft steel plates welded between the upper and lower connecting steel plates, vulcanized rubber injected through the circular holes of the upper connecting steel plate located at the cavity position between the parallel dog-bone holes soft steel plates, and a high-strength bolt system connecting the upper and lower connecting steel plates with the steel frame-support structure. Under the action of small or moderate earthquakes, the front and rear blocking soft steel plates and the parallel dog-bone hole soft steel plate rubber composite rectangular block of this energy dissipation and shock absorption device can play a role of large shear stiffness and effectively control the inter-layer displacement; under the action of large earthquakes, the front and rear blocking soft steel plates of this energy dissipation and shock absorption device gradually shear and yield to consume seismic energy, and as the deformation increases, the parallel dog-bone hole soft steel plate rubber composite rectangular block gradually degenerates from shear resistance to its own bending resistance, and the cross-section of the parallel dog-bone hole soft steel plate undergoes nearly equal strength bending plastic deformation to consume seismic energy, and the rubber and soft steel plates that pass through the parallel dog-bone hole soft steel plates cooperate in bending deformation and provide restoring force, which can effectively improve the energy dissipation and shock absorption effect and seismic toughness of the device.

[0005] Technical bottlenecks: 1. Viscous dampers are greatly affected by temperature and cannot exert their full shock absorption capacity at higher or lower temperatures. The aging of the medium used in the viscous damper leads to unstable damping force. Due to the high pressure and high speed flow of the medium inside the damper, the seals are easily damaged under long-term operation, resulting in leakage problems, so their maintenance costs are high; 2. Viscoelastic dampers and lead viscoelastic dampers also have problems such as sensitivity to ambient temperature and large environmental influence on damping parameters; 3. Metal dampers use the elastic-plastic hysteresis deformation generated when metal elements made of low-yield point steel and other materials yield to dissipate energy. They are less affected by external environment and temperature changes, but have problems such as low initial stiffness and large yield displacement, that is, they cannot provide sufficient stiffness under small earthquakes, and begin to consume energy under large earthquakes, but the recoverability is poor, making it difficult to perform performance-based design according to the seismic requirements of the structure. Technical bottlenecks: Energy dissipation and shock absorption device assembled between a steel frame and a herringbone steel support, which has the technical advantages of soft steel energy dissipation and rubber providing recovery force, and its manufacturing method.

The energy dissipation and shock absorption device of the present invention with parallel dog-bone holes in the bending mild steel plate and laminated rubber has a simple structure, is easy to prepare, convenient to assemble, and has low cost. The mild steel used in the energy dissipation and shock absorption device of the present invention is a common steel material in current building structures, and its cost is low. The punching process in the preparation process of the mild steel plate with dog-bone holes is a mature process for steel forming at present, and it has strong feasibility. The vulcanized laminated rubber poured inside the energy dissipation and shock absorption device is prepared by a hot vulcanization process, and the process technology is mature. Vulcanized rubber has the characteristics of high durability, high corrosion resistance, and high fatigue resistance, and is less affected by temperature, which overcomes the disadvantages of unstable damping force, high temperature sensitivity, and easy damage to seals caused by aging of the medium of viscous dampers, viscoelastic dampers, and lead viscoelastic dampers.

[0032] 2. The laminated rubber energy dissipation and shock-absorbing device of the parallel dog-bone hole soft steel plate of the present invention has two anti-seismic lines. Under the action of small or medium earthquakes, the front and rear blocking soft steel plates of the energy dissipation and shock-absorbing device can play a role of large shear stiffness and effectively control the inter-layer displacement; under the action of large earthquakes, the front and rear blocking soft steel plates of the energy dissipation and shock-absorbing device consume seismic energy by shear buckling deformation; and the cross-section of the parallel dog-bone hole soft steel plate consumes seismic energy by nearly equal strength bending plastic deformation. Compared with traditional soft steel dampers, the performance design of the energy dissipation and shock-absorbing device can be realized according to the seismic requirements of the structure.

[0033] 3. The energy dissipation and shock absorption device of the present invention with laminated rubber and parallel dog-bone holes in bending has the characteristics of synergistic force bearing of soft steel and laminated rubber. The soft steel has good plastic energy dissipation capacity, and the rubber has good elastic deformation capacity and recoverability. The advantages of the two materials are integrated. The rubber and the soft steel plates running through the parallel dog-bone holes in bending synergistically deform and provide restoring force, which effectively improves the energy dissipation and shock absorption effect and seismic toughness of the energy dissipation and shock absorption device.
