Description

Technical Field

[0001] The invention relates to a shear parallel circular hole soft steel plate laminated rubber-lead plate 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 to improve the ability of buildings to resist earthquake damage and collapse economically, efficiently and reasonably: the first is seismic design technology, that is, the use of efficient seismic structural systems and high-performance seismic components to improve the seismic resistance of structures; the second is seismic isolation design technology, that is, the use of 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, the use of energy dissipation and shock reduction devices to consume the energy input into the structure by the earthquake and reduce the damage to the structure. 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 shear parallel circular hole soft steel plate laminated rubber-lead plate energy dissipation and shock absorption device and method for a steel frame-support structure, belonging 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 an H-shaped steel frame beam, a lower connecting steel plate connected to a connecting end steel plate welded to the intersection area of ​​an H-shaped steel herringbone support, a shear parallel circular hole soft steel plate welded between the upper and lower connecting steel plates, front and rear blocking soft steel plates welded between the upper and lower connecting steel plates, a lead plate inserted into the middle of the cavity of the shear parallel circular hole soft steel plate and the front and rear blocking steel plates, left and right side blocking skin dog bone hole soft steel plates welded between the upper and lower connecting steel plates, a laminated vulcanized rubber poured into the cavity position of the shear parallel circular hole soft steel plate through the circular hole of the upper connecting steel plate, 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-shear parallel circular hole soft steel plates-rubber-lead plate combined structure of this energy dissipation and shock absorption device can play the role of large shear stiffness and effectively control the inter-story displacement; under the action of large earthquakes, the shear yield deformation process of the front and rear blocking soft steel plates-shear parallel circular hole soft steel plates-lead plates of this energy dissipation and shock absorption device consumes seismic energy, as the deformation increases, the plastic deformation of the lead plate consumes more seismic energy, the interface interaction of the shear parallel circular hole soft steel plates-rubber-lead plate combined structure consumes seismic energy, the rubber running through the shear parallel circular hole steel plates and the soft steel plates-lead plates synergistically deform 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 and manufacturing method assembled between steel frame and herringbone steel support, which has the technical advantages of energy dissipation of yield deformation of soft steel under shear, energy dissipation of plastic deformation of lead plate under shear, and restoring force provided by rubber.

[0028] Step 3: Prepare the metal components of the energy dissipation and shock absorption device. First, weld the shear parallel circular hole soft steel plate at the corresponding positions of the upper connecting belt circular hole steel plate and the lower connecting plate, and then weld the front and rear blocking soft steel plates. Insert the lead plate from the left or right side of the cavity between the shear parallel circular hole soft steel plate and the front and rear blocking soft steel plates to the middle of the cavity, and then weld the left and right sides of the skin dog bone hole blocking soft steel plates between the upper connecting belt circular hole steel plate and the lower connecting plate, and then weld the left and right sides of the skin dog bone hole blocking soft steel plates to the front and rear blocking soft steel plates.

The energy dissipation and shock absorption device of the present invention with a laminated rubber-lead plate and a bending parallel dog-bone hole mild steel plate has a simple structure, is easy to prepare, and is convenient to assemble. The mild steel and lead used in the energy dissipation and shock absorption device of the present invention are common materials on the market. The punching process in the preparation of the mild steel plate with dog-bone holes is a mature process for steel forming at present, and the use of a mold for hot-melt infusion to form the lead plate is also a mature process with 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, overcoming the disadvantages of viscous dampers, viscoelastic dampers, unstable damping force due to medium aging, high temperature sensitivity, and easy damage to seals.

[0034] 2. The energy dissipation and shock absorption device of the shear parallel circular hole soft steel plate laminated rubber-lead plate of the present invention has the characteristics of two seismic defense lines. Under the action of small or medium earthquakes, the front and rear blocking soft steel plates and the shear parallel circular hole soft steel plates of the energy dissipation and shock absorption device can play the role of large shear stiffness to effectively control the interlayer displacement, which is the first seismic defense line; under the action of large earthquakes, the front and rear blocking soft steel plates and the shear parallel circular hole soft steel plates of the energy dissipation and shock absorption device consume seismic energy through shear buckling deformation, and the plastic deformation of the lead plate consumes more seismic energy, which is the second seismic defense line. Compared with traditional soft steel dampers, the performance design of the energy dissipation and shock absorption device can be realized according to the seismic requirements of the structure.

[0035] 3. The shear parallel circular hole mild steel plate laminated rubber-lead plate energy dissipation and shock absorption device of the present invention has the synergistic force characteristics of mild steel-laminated rubber-lead plate. Mild steel has good buckling energy dissipation capacity, lead plate has strong plastic deformation energy dissipation capacity, and rubber has good elastic deformation capacity and recoverability. It combines the advantages of mild steel, lead plate, and rubber. The rubber running through the shear parallel circular hole mild steel plates and the mild steel plate-lead plate synergistically deform to dissipate energy 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.
