Description

Technical Field

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

[0002] The destruction and collapse of buildings caused by earthquakes have caused huge losses to the country's economic development and the safety of people's lives and property. 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 high-efficiency 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 effects of earthquakes on superstructures; 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 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 technologies 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 device and method for dissipating and damping energy of a steel frame-support structure with a laminated rubber-lead plate with parallel dog-bone holes, which belongs to the technical field of building damping. 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 parallel dog-bone hole soft steel plate welded between the upper and lower connecting steel plates, left and right side soft steel plates for sealing the skin dog-bone holes welded between the upper and lower connecting steel plates, a lead plate inserted and bonded to the front and rear ends of the parallel dog-bone hole soft steel plate cavity, front and rear blocking soft steel plates welded between the upper and lower connecting steel plates, a laminated vulcanized rubber poured into the parallel dog-bone hole soft steel plate cavity 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 and the parallel dog-bone hole soft steel plate rubber composite rectangular block of this energy dissipation and shock absorption device can play the 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, as the deformation increases, the lead plate plastically deforms to consume seismic energy, the parallel dog-bone hole soft steel plate rubber composite rectangular block gradually degenerates from shear resistance to its own bending resistance, the parallel dog-bone hole soft steel plate cross-section is bent plastically with nearly equal strength to consume seismic energy, the rubber and soft steel plates running through the parallel dog-bone hole soft steel plates cooperate to bend and 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 assembled between a steel frame and a herringbone steel support, which has the technical advantages of soft steel yield deformation energy dissipation, lead plate plastic deformation energy dissipation, and rubber providing recovery force, and its manufacturing method.

[0028] Step 3: Prepare the steel components of the energy dissipation and shock absorption device. First, weld the bending parallel dog bone hole soft steel plate at the corresponding positions of the upper connecting belt circular hole steel plate and the lower connecting plate, then weld the left and right sides of the soft steel plate with the skin dog bone hole, and then insert the rectangular lead plate for bonding and blocking from the front and back of the parallel dog bone hole soft steel plate cavity, and then weld the front and back blocking soft steel plates and weld the front and back blocking soft steel plates to the left and right sides of the skin dog bone hole blocking soft steel plates.

[0029] Step 4: Prepare the energy dissipation and shock absorption device of the laminated rubber-lead plate with parallel dog-bone holes in bending. The vulcanized rubber is prepared by hot vulcanization method, and the vulcanized rubber is poured into the cavity between the soft steel plates with dog-bone holes through the circular holes for pouring vulcanized rubber on the upper connecting plate.

[0030] Step 5: Assemble the steel frame. First, use high-strength bolts to connect and fix the bottom connecting plate of the H-shaped steel column to the foundation; then use high-strength bolts to connect the end plate of the H-shaped steel beam to the H-shaped steel column.

[0031] Step 6: Assemble the H-shaped steel herringbone support.

[0032] Step 7: Assemble the bending parallel dog bone hole soft steel plate laminated rubber-lead plate energy dissipation and shock absorption device. Use high-strength bolts to connect the upper connecting steel plate with round holes of the energy dissipation and shock absorption device to the bolt holes of the lower flange of the H-shaped steel beam, and then use high-strength bolts to connect the lower connecting steel plate of the energy dissipation and shock absorption device to the upper connecting end plate bolt holes welded in the upper end area of ​​the H-shaped steel herringbone support.

[0033] Compared with the prior art, the present invention relates to a bending parallel dog bone hole mild steel plate laminated rubber energy dissipation and shock absorption device and method for a steel frame-support structure, which has the following advantages: 1. 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, convenient to assemble, and has low cost. 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 present invention with parallel dog-bone hole soft steel plates laminated with rubber-lead plates has two anti-seismic defense lines. Under the action of small or medium earthquakes, the front and rear blocking soft steel plates of the energy dissipation and shock absorption device can play a role of large shear stiffness to effectively control the inter-layer displacement, which is the first defense line; under the action of large earthquakes, the front and rear blocking soft steel plates of the energy dissipation and shock absorption device consume seismic energy through shear buckling deformation, and the lead plates consume seismic energy through plastic deformation, which is the second defense line; the cross-section of the parallel dog-bone hole soft steel plates with bending consumes seismic energy through nearly equal strength bending plastic deformation. Compared with traditional soft steel dampers, the performance design of the energy dissipation and shock absorption device can be realized according to the seismic resistance requirements of the structure.

[0035] 3. The energy dissipation and shock absorption device of the soft steel plate with parallel dog-bone holes of the present invention has the characteristics of soft steel-laminated rubber-lead plate synergistic force bearing. The soft steel has good buckling energy dissipation capacity, the lead plate has strong plastic deformation energy dissipation capacity, and the rubber has good elastic deformation capacity and recoverability. It combines the advantages of the three materials of soft steel, lead plate and rubber. The rubber running through the soft steel plate with parallel dog-bone holes synergistically deforms with the soft steel plate and the lead plate 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.
