Description

Technical Field

[0001] The present invention relates to the technical field of anti - impact structures, and in particular to an anti - impact prefabricated wall. Background Art

[0002] The anti - impact prefabricated wall is an innovative building technology aimed at coping with the damage risks brought by natural disasters such as earthquakes and typhoons, as well as human impacts. Its background can be traced back to the last century. At that time, frequent earthquake events prompted people to have a profound awareness of the stability of building structures. Traditional building wall structures may have problems with relatively weak seismic resistance. Therefore, there was an urgent need for an efficient and reliable solution, and the anti - impact prefabricated wall technology emerged. It uses advanced building materials and processes and has excellent seismic resistance. These components are usually made of high - strength reinforced concrete or steel structures, which can effectively absorb and disperse impact forces, providing higher durability and safety. The anti - impact prefabricated wall technology has been widely applied and studied in recent decades and has achieved remarkable results. It is of great significance to the development of the construction industry and the safety construction of cities, creating a safer and more reliable living and working environment for us and providing strong guarantees.

[0003] After retrieval, the patent with Chinese Patent No. CN216041770U discloses an anti - seismic and anti - crack prefabricated explosion - proof wall, which includes two concrete columns and a concrete wall panel. There are two first embedded plates in the concrete wall panel. One side of each first embedded plate is fixedly connected with multiple groups of connecting rods. There are multiple groups of connecting pipes in each concrete column, and the connecting rods and the connecting pipes correspond one by one. There is a second embedded plate in each concrete column. One side of the two second embedded plates is fixedly connected with multiple fixing rods. There are multiple reserved holes on both sides of the concrete wall panel, and the fixing rods and the reserved holes correspond one by one. The second embedded plate is arranged between each group of connecting rods, and the connecting pipes and the reserved holes are staggered in sequence from top to bottom. The advantage of this wall is that through the cooperative connection between the connecting rods and the connecting pipes, and between the fixing rods and the reserved holes, the connection strength between the concrete wall panel and the concrete columns is improved, so that the overall seismic performance after the connection of the concrete wall panel and the concrete columns is improved. Compared with the prior art, the patent with Chinese Patent No. CN216041770U solves the problem that in the connection process of existing precast concrete components, the connection strength between the wall and the column is insufficient, and its overall seismic performance will be greatly reduced, which will have an adverse impact on the safety performance of the entire precast concrete building.

[0004] However, during the actual use of the above device, the seismic resistance of the front of the wall is improved. However, at the connection joints of the prefabricated wall, the lack of reinforcement and seismic treatment results in slightly insufficient anti-seismic and anti-impact capabilities at the joints. During the assembly process, the failure mechanism that may occur at the joints should be considered. Therefore, an anti-impact prefabricated wall is proposed. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that although the seismic resistance of the front of the wall is improved, at the connection joints of the prefabricated wall, the lack of reinforcement and seismic treatment results in slightly insufficient anti-seismic and anti-impact capabilities at the joints, and the failure mechanism that may occur at the joints should be considered during the assembly process. An anti-impact prefabricated wall is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An anti-impact prefabricated wall includes an anti-impact wall. An assembly base is arranged outside the anti-impact wall. Reinforcement components are symmetrically arranged at the connection joints of the anti-impact wall. The reinforcement components include rubber mounting pads arranged outside the anti-impact wall. Reinforcement steel members are arranged outside the rubber mounting pads. The reinforcement steel members can buffer the shear force generated at the joints of the wall components when an external load acts, and reduce the stress at the joints of the anti-impact wall components.

[0008] A damping and shock-absorbing mechanism is arranged at the external connection joints of the anti-impact wall. The damping and shock-absorbing mechanism includes connection pin seats arranged outside the anti-impact wall and the assembly base. A pin head is rotatably connected to the outside of the connection pin seat. A damper housing is arranged outside the pin head. An energy dissipation component is arranged inside the damper housing. The energy dissipation component can absorb and dissipate the impact received at the joints of the anti-impact wall. Two assembly grooves are arranged on the anti-impact wall, and an assembly fixing mechanism is arranged inside the assembly grooves.

[0009] The above technical solutions further include:

[0010] Assembly plates are symmetrically arranged outside the rubber mounting pads. Two assembly nails are arranged outside the assembly plates. The reinforcement components can be fixed at the connection joints of two anti-impact walls through the assembly nails.

[0011] The energy dissipation component includes an oil cavity arranged inside the damper housing. A guide rod is arranged inside the oil cavity. A piston is slidably connected to the outside of the guide rod. Several damping holes are arranged outside the piston. The oil cavity is filled with a damping medium. The piston can separate the medium on both sides, and the damping holes opened on the piston allow the medium to pass through. A sealing ring is arranged inside the oil cavity, and the oil cavity can be sealed through the sealing ring.

[0012] The assembly and fixing mechanism includes an assembly connecting pin arranged inside the assembly groove. The outer part of the assembly connecting pin is threadedly connected with a locking nut. An installation groove is provided at the corresponding position of the other impact-resistant wall body, and a pre-embedded connecting piece is arranged inside the installation groove.

[0013] The assembly connecting pin is threadedly connected with the pre-embedded connecting piece. By rotating the assembly connecting pin, the assembly connecting pin can be driven to insert into the installation groove. And by rotating the locking nut, the assembly connecting pin can be fixed.

[0014] The outer part of the impact-resistant wall body is symmetrically provided with assembled reinforcing ribs. The assembled reinforcing ribs include an assembly connecting groove arranged on the outer part of the impact-resistant wall body. A connecting piece is clamped outside the assembly connecting groove, and a reinforcing rib is fixedly connected to the outside of the connecting piece.

[0015] Threaded nails are symmetrically arranged on the outside of the reinforcing rib. The reinforcing rib can be fixed on the surfaces of the impact-resistant wall body and the assembly base respectively through the threaded nails.

[0016] A fireproof layer and a buffer pad are arranged inside the impact-resistant wall body. A rubber connecting layer is arranged on one side of the buffer pad away from the fireproof layer. A honeycomb board is arranged outside the rubber connecting layer. A plurality of honeycomb holes are opened inside the honeycomb board, and sand bags are filled inside the honeycomb holes.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, during the assembly process, the assembly connecting pin can be inserted into the pre-embedded connecting piece arranged inside the installation groove through the notch arranged inside the assembly groove. Then, the assembly connecting pin can be fixed through the locking nut to complete the connection between the two impact-resistant wall bodies. Finally, the assembly groove is completely filled with concrete for sealing, which can improve the connection effect of the connection of the impact-resistant wall bodies and effectively reduce the size of the joint. And the two reinforcement components arranged at the joint can further improve the connection strength between the two impact-resistant wall bodies. When an earthquake occurs or the impact-resistant wall body is impacted, the energy dissipation components arranged in the two damping and shock-absorbing mechanisms arranged at the joint of the impact-resistant wall bodies can absorb and dissipate the impact received at the joint of the impact-resistant wall bodies, thereby effectively reducing the vibration impact received at the joint and improving the seismic resistance of the joint of the impact-resistant wall bodies, greatly increasing the service life of the wall body.

[0019] 2. In the present invention, when an earthquake occurs, the frontal impact received by the impact-resistant wall will be reduced after passing through the buffer pad, rubber connection layer, and honeycomb board arranged inside the impact-resistant wall, and then through the sandbags filled inside the honeycomb holes, the impact force generated during the earthquake can be absorbed and buffered, thereby reducing the frontal impact of the earthquake on the impact-resistant wall and improving the earthquake resistance of the impact-resistant wall itself. The fireproof layer arranged inside the impact-resistant wall can effectively isolate high temperature, and during assembly, the connector arranged outside the reinforcing rib can be quickly positioned by being clamped with the assembly connection groove arranged outside the impact-resistant wall, which is convenient and fast and improves the assembly efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] As Figures 1-9 shown, an impact-resistant prefabricated wall proposed by the present invention includes an impact-resistant wall 1. An assembly base 3 is arranged outside the impact-resistant wall 1. Reinforcement components are symmetrically arranged at the connection of two impact-resistant walls 1. The reinforcement components include a rubber mounting pad 11 arranged outside the impact-resistant wall 1. A reinforcement steel member 2 is arranged outside the rubber mounting pad 11. The reinforcement steel member 2 can buffer the shear force generated at the joint of the wall members when an external load acts, and reduce the force at the joint of the impact-resistant wall 1 members.

[0033] A damping and shock-absorbing mechanism is arranged at the external connection of the impact-resistant wall 1. The damping and shock-absorbing mechanism includes a connection pin seat 26 arranged outside the impact-resistant wall 1 and the assembly base 3. A pin head 25 is rotatably connected outside the connection pin seat 26.

[0034] A damper housing 6 is arranged outside the pin head 25. An energy dissipation component is arranged inside the damper housing 6. The impact received at the joint of the impact-resistant wall 1 can be absorbed and dissipated by the energy dissipation component. Two assembly grooves 4 are arranged on the impact-resistant wall 1, and an assembly fixing mechanism is arranged inside the assembly grooves 4.

[0035] Assembly plates 12 are symmetrically arranged outside the rubber mounting pad 11. Two assembly nails 13 are arranged outside the assembly plates 12. The reinforcement components can be fixed at the connection of two impact-resistant walls 1 through the assembly nails 13.

[0036] An oil cavity 22 is arranged outside the assembly groove 4. A connection groove honeycomb hole 21 is clamped outside the oil cavity 22. A guide rod 23 is arranged at the bottom of the assembly groove 4. The guide rod 23 is threadedly connected to the seat assembly base 3.

[0037] The energy dissipation component includes an oil cavity 22 arranged inside the damper housing 6. A guide rod 23 is arranged inside the oil cavity 22. The guide rod 23 is slidably connected to a piston 24. Several damping holes are arranged outside the piston 24. A damping medium is filled inside the oil cavity 22. The medium can be separated on both sides by the piston 24, and the damping holes opened on the piston 24 allow the medium to pass through. A sealing ring 27 is arranged inside the oil cavity 22. The oil cavity 22 can be sealed through the sealing ring 27.

[0038] The assembly and fixing mechanism includes an assembly connecting pin 8 arranged inside the assembly groove 4. A locking nut 7 is threadedly connected to the outside of the assembly connecting pin 8. At the corresponding position of another impact-resistant wall 1, an installation groove 10 is provided. An embedded connecting part 9 is arranged inside the installation groove 10. The assembly connecting pin 8 is threadedly connected to the embedded connecting part 9. By rotating the assembly connecting pin 8, the assembly connecting pin 8 can be driven to insert into the installation groove 10. And by rotating the locking nut 7, the assembly connecting pin 8 can be fixed.

[0039] In this embodiment, during assembly, first, the embedded connecting part 9 is inserted into the installation groove 10 arranged inside the impact-resistant wall 1. Then, the assembly connecting pin 8 is inserted from the assembly groove 4 opened outside the other impact-resistant wall 1. There is a notch corresponding to the installation groove 10 outside the assembly groove 4, which can allow the assembly connecting pin 8 to be inserted. When the insertion of the assembly connecting pin 8 is completed, by rotating the assembly connecting pin 8, it can be connected to the embedded connecting part 9. As the assembly connecting pin 8 continuously penetrates, the connection strength between the two impact-resistant walls 1 will gradually increase. When the assembly connecting pin 8 is completely inserted, by rotating the locking nut 7, the assembly connecting pin 8 can be fixed, thus completing the connection of the impact-resistant wall 1. Finally, the internal space of the assembly groove 4 is filled with concrete, which can make the inside of the assembly groove 4 completely enclosed, thereby further strengthening the connection effect of the impact-resistant wall 1 and effectively reducing the joint size;

[0040] And two reinforcement components are also arranged at the joint of the two impact-resistant walls 1. The reinforcement components are connected to the surfaces of the two impact-resistant walls 1 through the assembly plates 12 arranged on the assembly nails 13. The rubber mounting pads 11 arranged on the outside of the reinforcement steel members 2 can buffer the shear force generated at the joint of the wall members when the external load acts, reduce the force at the joint of the wall members, effectively improve the impact resistance at the joint of the two impact-resistant walls 1, and make the joint not easily damaged;

[0041] When an earthquake occurs or the impact-resistant wall 1 is impacted, the piston 24 arranged inside the damper housing 6 can divide the damper housing 6 into two parts. During the reciprocating movement of the piston 24 inside the damper housing 6, the damping medium rapidly flows in the two separated cavities. Intense friction occurs between the molecules of the medium and between the medium and the piston 24. When the medium passes through the damping holes arranged on the piston 24, a huge throttling damping is generated. The resultant force of these effects becomes the damping force. The damping force generated during the flow converts the seismic kinetic energy into heat and dissipates it through the reciprocating movement of the piston 24 in the damping medium, gradually reducing the movement speed of the piston 24, achieving the purpose of damping energy consumption, thus effectively reducing the vibration impact received at the joint, improving the seismic capacity at the joint of the impact-resistant wall 1, and greatly increasing the service life of the wall.

[0042] Embodiment Two

[0043] AsFigures 1-9 As shown in the figure, based on the first embodiment, prefabricated reinforcing bars are symmetrically arranged outside the impact-resistant wall 1.

A connecting piece 15 is clamped outside the assembly connection groove 14, and a reinforcing bar 5 is fixedly connected outside the connecting piece 15;

[0044] Threaded nails 16 are symmetrically arranged outside the reinforcing bar 5. The reinforcing bar 5 can be respectively fixed on the surfaces of the impact-resistant wall 1 and the assembly base 3 through the threaded nails 16;

[0045] A fireproof layer 17 and a buffer pad 18 are arranged inside the impact-resistant wall 1. A rubber connection layer 19 is arranged on the side of the buffer pad 18 away from the fireproof layer 17. A honeycomb panel 20 is arranged outside the rubber connection layer 19. A number of honeycomb holes 21 are formed inside the honeycomb panel 20, and sandbags are filled inside the honeycomb holes 21.

[0046] In this embodiment, when an earthquake occurs, the frontal impact received by the impact-resistant wall 1 will be reduced after passing through the buffer pad 18, the rubber connection layer 19 and the honeycomb panel 20 arranged inside the impact-resistant wall 1. Then, through the sandbags filled inside the honeycomb holes 21, the impact force generated during the earthquake can be absorbed and buffered, thereby reducing the frontal impact of the earthquake on the impact-resistant wall 1 and improving the seismic resistance of the impact-resistant wall 1 itself;

[0047] The fireproof layer 17 arranged inside the impact-resistant wall 1 can effectively isolate high temperature and improve the heat insulation ability of the impact-resistant wall 1. During assembly, the connecting piece 15 arranged outside the reinforcing bar 5 can be quickly positioned by being clamped with the assembly connection groove 14 arranged outside the impact-resistant wall 1. After clamping, the reinforcing bar 5 can be quickly fixed to the surfaces of the impact-resistant wall 1 and the assembly base 3 through the threaded nails 16. The structure of the reinforcing bar 5 is a triangular support foot, and the assembly is rapid, which not only improves the assembly efficiency but also can effectively improve the stability of the impact-resistant wall 1, ensuring that the impact-resistant wall 1 is difficult to topple after being impacted by an earthquake.
