Description

Technical Field

[0001] This utility model relates to the field of swing wall technology, specifically to an energy-consuming unidirectional buffer swing wall. Background Technology

[0002] As an advanced seismic-resistant structural system, the swaying wall effectively dissipates seismic energy by allowing the wall to sway to a limited extent, thus significantly improving the seismic performance of building structures.

[0003] However, existing rocking wall technology still faces several challenges and shortcomings in practical applications. Although rocking walls can adapt to a certain degree of displacement and deformation, their displacement control capability is limited under extreme earthquake conditions, making it difficult to fully absorb and dissipate energy in the early stages. Furthermore, existing rocking wall systems often focus on the displacement adaptability of the structure, while neglecting the integration and optimization of energy dissipation mechanisms, failing to fully utilize structural deformation for efficient energy dissipation. Existing rocking wall systems have limited buffering effects against unidirectional impacts, lacking effective mechanisms for targeted absorption of instantaneous impact forces, thus increasing the risk of localized damage. Existing rocking wall systems cannot provide sufficient buffering protection under large deformation conditions, lacking self-recovery energy dissipation characteristics after impact, and lacking long-term stability and seismic resilience. After damage, the replacement and repair of key components in existing rocking wall systems are highly complex, affecting the long-term maintenance efficiency and economy of the structure.

[0004] Therefore, there is an urgent need for a new swing wall system that can dynamically adjust displacement and efficiently dissipate energy while ensuring structural safety, provide unidirectional buffer protection when the wall is impacted, have self-recovering energy dissipation characteristics after impact, and be easy to replace and repair. Summary of the Invention

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] The viscous energy dissipation mechanism includes a horizontal guide rod and a damper housing. The damper housing is disposed in the middle of the displacement amplification and steering mechanism. A viscous fluid is disposed in the damper housing. One end of the horizontal guide rod passes through the damper housing and is disposed in the viscous fluid. The other end is disposed at the connection between the perforated support arm and the lower support arm.

[0011] The limiting mechanism is provided in multiple ways, including a support plate and a limiting plate. The upper end of the support plate is connected to the lower end face of the middle connecting plate, the lower end of the support plate is located in the middle of the limiting plate, the upper end of the limiting plate is located in the middle of the support plate, and the lower end of the limiting plate is connected to the upper end face of the lower connecting plate.

[0012] Furthermore, a support arm connecting plate is symmetrically provided on the lower end face of the middle connecting plate and the upper end face of the lower connecting plate, and the upper ends of the upper support arm and the perforated support arm, as well as the lower ends of the two lower support arms, are respectively connected to the support arm connecting plate.

[0013] Furthermore, the upper support arm, the perforated support arm, and the two lower support arms are arranged in a diamond shape.

[0014] Furthermore, a connector is provided at the connection between the perforated support arm and the lower support arm. The lower end of the perforated support arm and the upper end of the lower support arm are both connected to the connector. The end of the horizontal guide rod away from the damper housing passes through the connector.

[0015] Furthermore, the horizontal guide rod is T-shaped and includes a short rod and a long rod. The upper and lower ends of the short rod are attached to the upper and lower inner walls of the damper housing.

The upper end face of the long rod passing through the connector is provided with teeth.

[0016] Furthermore, the perforated support arm is provided with a pawl, one end of which is connected to the perforated support arm and the other end is engaged with the teeth.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model provides an energy-dissipating unidirectional buffer swing wall, which achieves efficient amplification of wall displacement under earthquakes or external force impacts. Under earthquakes or external force, the bending energy-dissipating damper first dissipates bending energy, and the upper small displacement is amplified by the displacement amplification and steering mechanism. The vertical displacement is amplified and turned into a horizontal displacement by the upper support arm and the perforated support arm. Then, the energy is dissipated by the viscous energy-dissipating mechanism. The horizontal guide rod moves horizontally in the viscous fluid, thereby generating viscous damping and preventing the vertical displacement of the wall. At the same time, the unidirectional buffer damping energy dissipation mechanism can fully utilize the damping effect while maximizing the dissipation of external impact energy. It is also equipped with a limiting mechanism to prevent excessive displacement, effectively improving the seismic performance and safety of the building. This utility model not only enhances the sensitivity of the energy dissipation device to structural deformation, but also enables the energy dissipation mechanism to be activated under small displacement conditions, thereby participating in the energy absorption process earlier and improving energy dissipation efficiency. It can specifically cope with different types of earthquake loading and ensures efficient energy dissipation under various working conditions, reducing the cumulative damage to the structure.

[0023] 2. This utility model sets up a one-way buffer mechanism through a tooth-pawl structure. When the wall on one side moves vertically upward, it can effectively hinder the immediate response of the energy-consuming device on that side, thereby prompting the energy-consuming device on the other side to fully exert its energy-consuming capacity. It can provide directional buffer protection when the device is impacted, reducing the risk of damage to the device.

[0024] 3. This utility model provides return springs above and below the inner wall of the damper housing near the connector. When the horizontal guide rod moves outward, the return spring is compressed by the short rod. When the horizontal guide rod stops moving, it slowly returns to its initial position under the elastic force of the return spring, thus enabling the energy dissipation device to recover after being impacted.

[0025] 4. This utility model adopts modular and standardized design principles, which ensures that these components can be quickly and conveniently replaced and maintained after the energy-consuming device is damaged, which greatly reduces maintenance costs and extends the service life of the entire swing wall system.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] Example:

[0042] like Figure 1 and Figure 2 As shown, this embodiment provides an energy-consuming unidirectional buffer swing wall, including a wall body 1 and two energy-consuming devices. Spaces are reserved on both sides of the bottom of the wall body 1, and the two energy-consuming devices are respectively set in the spaces. The energy-consuming devices include a bending energy-consuming damper, a displacement amplification and steering mechanism, a viscous energy-consuming mechanism and a limiting mechanism.

[0043] Specifically, such as Figure 7As shown, the bending energy dissipation damper includes an upper connecting plate 2, multiple bending steel plates 5, and a middle connecting plate 3. The upper connecting plate 2 and the middle connecting plate 3 are arranged in parallel, and the upper connecting plate 2 is welded to the top of the bottom space of the wall 1. The bending steel plates 5 are vertically and equally spaced between the upper connecting plate 2 and the middle connecting plate 3. Under the action of earthquake, when the wall 1 undergoes bending deformation, the bending energy dissipation damper first consumes the energy generated by its bending deformation.

[0044] Furthermore, such as Figure 8 As shown, the displacement amplification and steering mechanism includes an upper support arm 7, a perforated support arm 8, and two lower support arms 15. The upper support arm 7, the perforated support arm 8, and the two lower support arms 15 are arranged in a diamond shape, and bolt holes are opened at both ends of the upper support arm 7, the perforated support arm 8, and the two lower support arms 15. The displacement amplification and steering mechanism amplifies the vertical displacement of the bending energy dissipation damper and converts it into horizontal movement.

[0045] Support arm connecting plates 6 are symmetrically welded to the bottom of the middle connecting plate 3 and the top of the lower connecting plate 4. The support arm connecting plates 6 are cuboids, and each of the two support arm connecting plates 6 has two screw holes. The upper support arm 7 and the perforated support arm 8 are respectively connected to the two screw holes of the support arm connecting plate 6 at the bottom of the middle connecting plate 3 by support arm connecting bolts 19. The lower ends of the upper support arm 7 and the perforated support arm 8 are respectively connected to the lower support arm 15. The lower ends of the two lower support arms 15 are respectively connected to the two screw holes of the support arm connecting plate 6 at the top of the lower connecting plate 4 by support arm connecting bolts 19. The bottom of the lower connecting plate 4 is flush with the bottom of the space reserved at the bottom of the wall 1.

[0046] A connector 14 is provided at the connection between the perforated support arm 8 and the lower support arm 15. The connector 14 includes two side plates and two connecting rods. The two side plates are arranged vertically and parallel to each other and are integrally connected by the two connecting rods. The two connecting rods are connected in parallel to the same end of the two side plates, making the connector 14 as a whole rectangular parallelepiped. Bolt holes are provided on both side plates. The lower end of the perforated support arm 8 is located inside the connector 14 and is connected to the side plate of the connector 14 by bolts. The upper end of the lower support arm 15 is located inside the connector 14 and is connected to the other side plate of the connector 14 by bolts.

[0047] The upper support arm 7, the perforated support arm 8, and the lower support arm 15 must be made of high-strength steel to ensure their strength. The arm length and angle of the upper support arm 7, the perforated support arm 8, and the lower support arm 15 can be adjusted according to the actual project to ensure that the displacement amplification and steering mechanism will not come into contact with the wall 1 during operation.

[0048] In this embodiment, as Figure 9As shown, the viscous energy dissipation mechanism includes a horizontal guide rod 13 and a damper housing 16. The damper housing 16 is located at the center of the displacement amplification and steering mechanism. A viscous fluid 17 is disposed within the damper housing 16. A hole is formed on the side wall of the damper housing 16 near the horizontal guide rod 13, as shown... Figure 4 and Figure 5 As shown, the horizontal guide rod 13 is T-shaped, including a short rod and a long rod. The short rod is placed in the viscous fluid 17 and its upper and lower ends are respectively attached to the upper and lower inner walls of the damper housing 16. The long rod is vertically fixed to the side wall of the short rod and passes through the hole and connector 14 on the damper housing 16 in sequence. The horizontal guide rod 13 is slidably connected to the damper housing 16 and the connector 14. The horizontal guide rod 13 does not directly affect the operation of the perforated support arm 8, the connector 14 and the lower support arm 15.

[0049] A tooth 12 is welded to the upper end face of the horizontal guide rod 13, which passes through the connector 14. A screw hole is reserved near the lower 1 / 3 of the perforated support arm 8. A pawl 10 is fixed on the perforated support arm 8 by a connecting bolt 9 and a spring 11. Specifically, one end of the pawl 10 is connected to the screw hole reserved near the lower 1 / 3 of the perforated support arm 8 by a connecting bolt 9, and the other end of the pawl 10 is engaged with the tooth 12. A through hole is opened between the screw hole near the lower 1 / 3 of the perforated support arm 8 and the bolt hole at the lower end. A fixing post is welded in the through hole. The fixing post is longer than the length of the through hole. One end of the spring 11 is welded to the fixing post, and the other end is welded to the pawl 10. The spring 11 limits and buffers the pawl 10.

[0050] The length of tooth 12 is 1 / 3 of the length of horizontal guide rod 13. Tooth 12 and perforated support arm 8 are arranged on the side of energy dissipation device away from wall 1. The specific arrangement position can be adjusted according to the actual engineering site. The length of horizontal guide rod 13 can be adjusted according to the actual engineering to ensure that when it works in conjunction with damper housing 16, there is displacement in both sides that basically meets the requirements of earthquake.

[0051] A connecting rod is welded to the side of the damper housing 16 away from the horizontal guide rod 13. The connecting rod and the horizontal guide rod 13 are on the same horizontal line. The other end of the connecting rod is fixed to the connection between the upper support arm 7 and the lower support arm 15 by bolts. The end of the connecting rod is located between the lower end of the upper support arm 7 and the upper end of the lower support arm 15.

[0052] The force generated by the energy dissipation of the bending energy-dissipating damper is transmitted downward through the middle connecting plate 3. Under the action of the force, the upper support arm 7 and the perforated support arm 8 extend to both sides simultaneously, which also drives the two lower support arms 15 to extend to both sides. When the perforated support arm 8 extends, the pawl 10 drives the horizontal guide rod 13 to move horizontally. The direction of movement of the horizontal guide rod 13 is the same as the extension direction of the perforated support arm 8 and the lower support arm 15 on the same side as the perforated support arm 8. When the upper support arm 7 and the lower support arm 15 on the same side extend, they drive the connecting rod to move horizontally. The connecting rod drives the damper housing 16 to move horizontally. The direction of movement of the connecting rod and the damper housing 16 is opposite to the direction of movement of the horizontal guide rod 13, so that the horizontal guide rod 13 and the damper housing 16 make relative movement, causing the short rod of the horizontal guide rod 13 to move in the viscous fluid 17, generating viscous damping and dissipating the vibration energy of the seismic input device.

[0053] like Figure 3 As shown, a return spring 18 is fixed above and below the inner wall of the damper housing 16 near the connector 14. The return spring 18 is located between the short rod and the inner wall of the damper housing 16. When the horizontal guide rod 13 is displaced outward, the return spring 18 will be compressed by the short rod. When the horizontal guide rod 13 stops moving, the horizontal guide rod 13 will slowly return to the initial position under the elastic force of the return spring 18.

[0054] When the upper support arm 7 and the perforated support arm 8 retract inward, the teeth 12 and the pawl 10 do not affect the movement of the horizontal guide rod 13. At this time, the horizontal guide rod 13 does not move, and the viscous energy dissipation mechanism does not work. When the upper support arm 7 and the perforated support arm 8 extend outward, the pawl 10 and the spring 11 will cause the horizontal guide rod 13 to move relative to the damper housing 16 due to the obstruction of the teeth 12. The viscous energy dissipation mechanism starts to work, thereby realizing the one-way buffering effect.

[0055] Furthermore, there are two limiting mechanisms, arranged on both sides of the displacement amplification and steering mechanism, which do not affect the normal operation of the displacement amplification and steering mechanism, such as... Figure 6 As shown, the limiting mechanism includes a support plate 21 and a limiting plate 23. The support plate 21 is L-shaped, and the limiting plate 23 is F-shaped. The support arm connecting plate 6 at the bottom of the middle connecting plate 3 is symmetrically welded with upper L-shaped contact plates 20 on both the front and rear sides. The support arm connecting plate 6 at the top of the lower connecting plate 4 is symmetrically welded with lower L-shaped contact plates 24 on both the front and rear sides. The upper end of the support plate 21 is welded to the upper L-shaped contact plate 20. The lower end of the support plate 21 is located between the two extension arms of the limiting plate 23. The lower end of the limiting plate 23 is welded to the lower L-shaped contact plate 24. Buffer blocks 22 are bonded to the opposite surfaces of the two extension arms of the limiting plate 23. In this embodiment, the buffer blocks 22 are made of rubber.

[0056] When the wall 1 moves vertically, the lower end of the support plate 21 moves downward between the two extension arms of the limiting plate 23, and the support plate 21 and the limiting plate 23 are relatively displaced. When the displacement is large, the support plate 21 compresses the buffer block 22 on the extension arm below the limiting plate 23. The buffer block 22 generates a force opposite to the displacement direction of the support plate 21 due to its own elasticity, thereby limiting the displacement of the support plate 21 and preventing excessive displacement.

[0057] The specific dimensions of the support plate 21 and the limiting plate 23 are determined by the actual project to ensure that when the device is not working, the lower end of the support plate 21 is between the two extension arms of the limiting plate 23, and the elastic modulus of the buffer block 22 must meet the actual use requirements.

[0058] The working principle of this embodiment is as follows:

[0059] Under earthquake action, when bending failure of wall 1 is the main cause, the bending energy dissipation damper plays a major role. When shear failure is the main cause, the viscous energy dissipation mechanism consumes the horizontal shear force. When bending-shear failure occurs, the three mechanisms work together. The force generated by the energy dissipation of the bending energy dissipation damper is transmitted downward through the middle connecting plate 3. The upper support arm 7, the perforated support arm 8, and the two lower support arms 15 begin to extend to both sides under the action of the force, while driving the horizontal guide rod 13 and the damper housing 16 to move relative to each other. At this time, the horizontal guide rod 13 accelerates under the action of the pawl 10, amplifying the upper displacement and converting the vertical force into horizontal movement. The short rod of the horizontal guide rod 13 moves in the viscous fluid 17, thereby generating viscous damping and dissipating earthquake energy. At the same time, the support plate 21 and the limiting plate 23 restrict the vertical force to avoid excessive displacement.

[0060] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
