Description

Technical Field

[0001] This application relates to the field of building connection technology, and in particular to a prefabricated building connection device with shock absorption function. Background Technology

[0002] Prefabricated buildings have become an important development direction of modern building industrialization due to their advantages such as fast construction speed and less environmental pollution. However, the connection performance between prefabricated components directly affects the seismic resistance and durability of the overall structure.

[0003] In recent years, with the development of building vibration reduction and isolation technology, a type of prefabricated building connection equipment with vibration reduction function has emerged. This equipment includes a connecting plate and a vibration reduction mechanism. The two connecting plates are connected to the prefabricated building, and the vibration reduction mechanism is fixed between the two connecting plates by bolts. When an earthquake occurs, the connection equipment absorbs the energy of the seismic wave through the vibration reduction mechanism, thereby achieving the purpose of vibration reduction.

[0004] However, existing prefabricated building connection equipment with shock absorption function has a complex structure and is difficult to assemble and maintain, making it difficult to promote on a large scale in ordinary prefabricated buildings. Summary of the Invention

[0005] In order to reduce the problems of complex structure and difficult assembly and maintenance of prefabricated building connection equipment with vibration damping function, this application provides a prefabricated building connection equipment with vibration damping function.

[0006] This application provides a prefabricated building connection device with shock absorption function, which adopts the following technical solution:

[0007] A prefabricated building connection device with vibration damping function, comprising:

[0008] The upper connecting plate is fixedly connected to the upper prefabricated building, and a guide hole is provided in the center of the upper connecting plate;

[0009] The lower connecting plate is fixedly connected to the lower prefabricated building. The lower connecting plate is provided with a positioning groove, and the axis of the positioning groove coincides with the axis of the guide hole.

[0010] A support base is fixedly mounted on the lower connecting plate, and a support hole is provided on the support base.

[0011] The P-wave reduction component is mounted on the lower connecting plate. The lower end of the P-wave reduction component abuts against the positioning groove, and the upper end of the P-wave reduction component abuts against the guide hole. The P-wave reduction component absorbs and reduces seismic P-waves.

[0012] The shear wave reduction component is mounted on the support base and passes through the support hole. The shear wave reduction component absorbs and reduces seismic shear waves.

[0013] By adopting the above technical solution, the upper and lower connecting plates are fixedly connected to the prefabricated building, providing space for the connection equipment. The shear wave reduction component is fixedly connected to the upper and lower connecting plates through the support base. When an earthquake occurs, the longitudinal wave reduction component absorbs the energy generated by the longitudinal wave through elastic deformation, reducing the impact of the longitudinal wave on the prefabricated building. The shear wave reduction component absorbs the energy generated by the shear wave by causing some parts of the structure to preferentially undergo material yielding or plastic deformation, reducing the impact of the shear wave on the prefabricated building, thereby achieving the purpose of vibration reduction in the prefabricated building.

[0014] Optional, the longitudinal wave reduction components include:

[0015] The guide rod is fixedly installed in the positioning groove, and the other end of the guide rod passes through the guide hole.

[0016] A disc spring assembly is fitted onto the guide rod. One end of the disc spring assembly abuts against the positioning groove, and the other end abuts against the guide hole.

[0017] By adopting the above technical solution, the guide rod is fixedly set in the positioning groove to provide support for the disc spring assembly, reducing the damage caused by large lateral displacement of the disc spring assembly. The two ends of the disc spring assembly abut against the positioning groove and the guide hole respectively, so that the disc spring assembly is subjected to longitudinal pressure, making the connection between the disc spring assemblies more stable. At the same time, it can provide support force for the upper and lower connecting plates. The guide rod and the disc spring assembly work together to make the longitudinal wave reduction component more stable and improve the vibration reduction capability of the connected equipment.

[0018] Optional, the shear wave reduction components include:

[0019] A connecting frame is provided between the upper connecting plate and the lower connecting plate. A sliding groove is provided inside the connecting frame, and a guide groove is provided on the sliding groove. The sliding groove and the guide groove are connected.

[0020] A threaded rod, one end of which is fixedly set at the bottom of the slide groove, and the other end of which extends through the guide groove to the outside of the connecting frame;

[0021] The nut is fitted onto the end of the threaded rod away from the connecting frame, and the nut is threadedly connected to the threaded rod.

[0022] The extrusion plate is sleeved on the threaded rod and positioned between the nut and the connecting bracket.

[0023] The slider is slidably positioned within the groove.

[0024] A connecting rod, one end of which is rotatably connected to the extrusion plate, and the other end of which passes through the guide groove and is rotatably connected to the slider;

[0025] The energy-consuming steel bar has one end rotatably installed in the support hole, and the other end is fixedly connected to the slider.

[0026] A spring is fitted onto one end of the threaded rod near the connecting frame. One end of the spring is fixedly connected to the extrusion plate, and the other end of the spring is fixedly connected to the connecting frame.

[0027] By adopting the above technical solution, the connecting frame connects multiple sets of energy-dissipating steel bars, forming a fixed connection between the energy-dissipating steel bars and the upper and lower connecting plates. This facilitates the transmission and absorption of seismic shear wave energy by the energy-dissipating steel bars. Nuts and compression plates are fitted onto the threaded rod. By rotating the nut, the compression plate can be moved closer to the connecting frame. The two ends of the connecting rod are rotatably connected to the compression plate and the slider, respectively, so that the movement of the connecting frame is transmitted to the slider, causing the slider to move the energy-dissipating steel bars along the slide groove. The spring can provide support and reaction force for the compression plate and nut, making the nut's fixation of the compression plate more stable. When replacing the energy-dissipating steel bars, the staff can rotate the nut to detach the energy-dissipating steel bars from the support base, thereby realizing the quick disassembly and assembly of the energy-dissipating steel bars and reducing the difficulty of assembling and maintaining the connecting equipment.

[0028] Optionally, four sets of energy-consuming steel bars, sliders, and connecting rods are symmetrically arranged along the horizontal and vertical axes of the connecting plate.

[0029] By adopting the above technical solution, each connecting plate can simultaneously control the installation and fixing of four energy-consuming steel bars, reducing the difficulty of installing and disassembling the energy-consuming steel bars, making it faster for workers to assemble and maintain the energy-consuming steel bars, and facilitating the large-scale promotion of prefabricated building connection equipment with shock absorption function in ordinary prefabricated buildings.

[0030] Optionally, four sets of shear wave reduction assemblies are provided along the periphery of the upper and lower connecting plates.

[0031] By adopting the above technical solution, the shear wave reduction component is set on the periphery of the upper and lower connecting plates, which enables the shear wave reduction component to absorb seismic shear waves from all directions, thereby improving the vibration reduction capability of the connecting equipment.

[0032] Optionally, each support base is provided with two support holes, and each support base is rotatably connected to two sets of energy-dissipating steel bars of the transverse wave reduction assembly.

[0033] By adopting the above technical solution, the support base can simultaneously support energy-consuming steel bars on two different planes, reducing the installation difficulty of the connecting equipment.

[0034] Optionally, the energy-consuming steel bar is threadedly fixed to the slider.

[0035] By adopting the above technical solution, staff can quickly assemble and disassemble energy-consuming steel bars on-site, resulting in low maintenance costs.

[0036] Optionally, the disc spring assembly consists of multiple disc springs.

[0037] By adopting the above technical solutions, multiple disc springs improve the longitudinal load-bearing capacity of the disc spring assembly, enhance the disc spring assembly's ability to absorb seismic longitudinal waves, and improve the vibration damping capacity of the connected equipment.

[0038] Optionally, the disc spring assembly can be made of alloy steel.

[0039] By adopting the above technical solution, the material of the disc spring assembly is alloy steel, which enables the disc spring assembly to support a large load with a small deformation, thereby improving the supporting force of the disc spring assembly and ensuring the stability of the connected equipment.

[0040] Optionally, the material for the energy-consuming steel bar is duplex steel.

[0041] By adopting the above technical solution, the material of the energy-dissipating steel bar is dual-phase steel, which has both high strength and high ductility. This can effectively improve the energy-dissipating steel bar's ability to absorb seismic shear waves and improve the vibration reduction capability of the connected equipment.

[0042] In summary, the embodiments of the present invention provide a prefabricated building connection device with shock absorption function, which includes at least one of the following beneficial technical effects:

[0043] 1. The upper and lower connecting plates are fixedly connected to the prefabricated building, providing space for the connection equipment. The shear wave reduction component is fixedly connected to the upper and lower connecting plates through the support base. When an earthquake occurs, the longitudinal wave reduction component absorbs the energy generated by the longitudinal wave through elastic deformation, reducing the impact of the longitudinal wave on the prefabricated building. The shear wave reduction component absorbs the energy generated by the shear wave by causing some parts of the structure to preferentially undergo material yielding or plastic deformation, reducing the impact of the shear wave on the prefabricated building, thereby achieving the purpose of vibration reduction in the prefabricated building.

[0044] 2. By adopting the above technical solution, the connecting frame connects multiple sets of energy-dissipating steel bars, making the energy-dissipating steel bars fixedly connected to the upper and lower connecting plates. This facilitates the transmission and absorption of seismic shear wave energy by the energy-dissipating steel bars. Nuts and compression plates are fitted onto the threaded rod. By rotating the nut, the compression plate can be moved closer to the connecting frame. The two ends of the connecting rod are rotatably connected to the compression plate and the slider, respectively, so that the movement of the connecting frame is transmitted to the slider and the slider moves the energy-dissipating steel bars along the slide groove. The spring can provide support and reaction force for the compression plate and nut, making the nut more stable in fixing the compression plate. When replacing the energy-dissipating steel bars, the workers can rotate the nut to detach the energy-dissipating steel bars from the support base, thereby realizing the quick disassembly and assembly of the energy-dissipating steel bars and reducing the difficulty of assembling, maintaining and connecting the equipment.

[0052] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0053] Combination Figure 1 , Figure 2 and Figure 3 This application discloses a prefabricated building connection device with shock absorption function, including: an upper connecting plate 11, a lower connecting plate 12, a support base 13, a longitudinal wave reduction component 2, and a transverse wave reduction component 3. The upper connecting plate 11 is fixedly connected to the upper prefabricated building, and a guide hole 14 is provided in the center of the upper connecting plate 11. The lower connecting plate 12 is fixedly connected to the lower prefabricated building, and a positioning groove 15 is provided on the lower connecting plate 12. The axis of the positioning groove 15 coincides with the axis of the guide hole 14. The support base 13 is fixedly installed on the lower connecting plate 12, and a support hole 16 is provided on the support base 13. The longitudinal wave reduction component 2 is installed on the lower connecting plate 12, and the lower end of the longitudinal wave reduction component 2 abuts against the positioning groove 15, and the upper end of the longitudinal wave reduction component 2 abuts against the guide hole 14. The longitudinal wave reduction component 2 absorbs and reduces seismic longitudinal waves. The transverse wave reduction component 3 is installed on the support base 13 and passes through the support hole 16. The transverse wave reduction component 3 absorbs and reduces seismic transverse waves.

[0054] In this embodiment, the upper connecting plate 11 is rectangular and is fixedly connected to the upper prefabricated building by bolts. A guide hole 14 is provided at the center of the lower surface of the upper connecting plate 11. The guide hole 14 is circular. The lower connecting plate 12 is rectangular and is fixedly connected to the lower prefabricated building by bolts. A positioning groove 15 is provided at the center of the upper surface of the lower connecting plate 12. The positioning groove 15 is cylindrical. The guide hole 14 and the positioning groove 15 can accurately position the longitudinal wave reduction component 2 at the center of the connecting device. The support base 13 is fixedly disposed on the upper surface of the lower connecting plate 12 and near the vertex of the lower surface of the upper connecting plate 11. The support base 13 is respectively located along the four vertices of the lower surface of the upper connecting plate 11 and the upper surface of the lower connecting plate 12. Eight supports are fixedly installed at the four vertices of the surface. The support base 13 can be integrally formed with the upper connecting plate 11 and the lower connecting plate 12, or it can be bolted or welded. In this embodiment, no specific limitation is made. Each support base 13 is provided with two mutually perpendicular support holes 16. Each support base 13 is rotatably connected to two sets of shear wave reduction components 3. The longitudinal wave reduction component 2 is placed at the center of the lower connecting plate 12. The shear wave reduction component 3 is arranged in an X shape. Four sets of shear wave reduction components 3 are arranged along the periphery of the upper connecting plate 11 and the lower connecting plate 12. Each set of shear wave reduction components 3 is rotatably connected to four support bases 13. The arrangement of multiple sets of shear wave reduction components 3 can enable the connecting device to absorb seismic shear waves from multiple directions and enhance the vibration reduction capability of the connecting device.

[0055] In practical application, since this prefabricated building connection equipment is mainly used for large-scale promotion in ordinary prefabricated buildings and is not suitable for higher-rise or prefabricated buildings with high seismic resistance requirements, the prefabricated buildings mentioned in this application embodiment are mainly low-rise prefabricated buildings or ordinary prefabricated buildings. The upper prefabricated building that is fixedly connected to the upper connecting plate 11 by bolts is mainly the bottom plate of the low-rise prefabricated building, and the lower prefabricated building that is fixedly connected to the lower connecting plate 12 by bolts is mainly the top plate or foundation support column of the low-rise prefabricated building. The connection between the upper and lower prefabricated buildings... Sufficient space should be provided for installing the connection equipment and ensuring that staff can enter the installation space to assemble and maintain the connection equipment. When an earthquake occurs, the P-waves, due to their faster propagation speed, reach the prefabricated building first. The P-wave reduction component 2 absorbs the energy generated by the P-waves through elastic deformation, reducing the impact of the P-waves on the prefabricated building. When the S-waves reach the prefabricated building, the S-wave reduction component 3 absorbs the energy generated by the S-waves by causing partial material yielding or plastic deformation, reducing the impact of the S-waves on the prefabricated building, thus enabling the connection equipment to achieve the purpose of vibration reduction.

[0056] Combination Figure 2In one specific embodiment, the longitudinal wave reduction assembly 2 includes: a guide rod 21 and a disc spring assembly 22. The guide rod 21 is fixedly disposed in the positioning groove 15, and the other end of the guide rod 21 passes through the guide hole 14. The disc spring assembly 22 is sleeved on the guide rod 21, with one end of the disc spring assembly 22 abutting against the positioning groove 15 and the other end of the disc spring assembly 22 abutting against the guide hole 14.

[0057] In this embodiment, the guide rod 21 is cylindrical and fixedly positioned at the center of the positioning groove 15 of the lower connecting plate 12. The guide rod 21 and the lower connecting plate 12 can be bolted or welded together; no specific limitation is made in this embodiment. The disc spring assembly 22 is composed of multiple disc springs 38 stacked in the same direction. The disc springs 38 are disc-shaped and have through holes in their centers. The disc spring assembly 22 is made of alloy steel, which allows the disc spring assembly 22 to support a large load with minimal deformation, thereby improving the supporting force of the disc spring assembly 22 and ensuring the support stability of the connected equipment.

[0058] In practical use, when no earthquake occurs, the disc spring assembly 22 is fixedly installed between the upper connecting plate 11 and the lower connecting plate 12. It deforms under the pressure applied by the prefabricated building, and the disc spring 38 provides support to the prefabricated building. When an earthquake occurs, after the seismic longitudinal wave is transmitted to the prefabricated building, the prefabricated building shakes vertically due to the influence of the seismic longitudinal wave. The disc spring 38 undergoes elastic deformation to absorb the kinetic energy of the prefabricated building, so that the prefabricated building remains stable, thereby achieving the purpose of shock reduction.

[0059] Combination Figure 1 and Figure 3In one specific embodiment, the transverse wave reduction assembly 3 includes: a connecting frame 31, a threaded rod 32, a nut 33, a pressing plate 34, a slider 35, a connecting rod 36, an energy-consuming steel rod 37, and a spring 38. The connecting frame 31 is disposed between the upper connecting plate 11 and the lower connecting plate 12. A sliding groove 17 is provided inside the connecting frame 31, and a guide groove 18 is provided on the sliding groove 17. The sliding groove 17 and the guide groove 18 are connected. One end of the threaded rod 32 is fixedly disposed at the bottom of the sliding groove 17, and the other end of the threaded rod 32 extends through the guide groove 18 to the outside of the connecting frame 31. The nut 33 is sleeved on the end of the threaded rod 32 away from the connecting frame 31. The rod 32 is threaded, the extrusion plate 34 is sleeved on the threaded rod 32, the extrusion plate 34 is set between the nut 33 and the connecting frame 31, the slider 35 is slidably set in the slide groove 17, one end of the connecting rod 36 is rotatably connected to the extrusion plate 34, the other end of the connecting rod 36 passes through the guide groove 18 and is rotatably connected to the slider 35, one end of the energy-consuming steel rod 37 is rotatably set in the support hole 16, the other end of the energy-consuming steel rod 37 is fixedly connected to the slider 35, and the spring 38 is sleeved on the end of the threaded rod 32 near the connecting frame 31, one end of the spring 38 is fixedly connected to the extrusion plate 34, and the other end of the spring 38 is fixedly connected to the connecting frame 31.

[0060] In this embodiment, the connecting frame 31 is X-shaped, and the sliding groove 17 inside the connecting frame 31 is an X-shaped circular through hole. A guide groove 18 is provided at the end of the sliding groove 17 away from the longitudinal wave reduction component 2. The guide groove 18 is an X-shaped square groove, and a circular hole is formed at the center of the overlapping part of the guide grooves 18. The threaded rod 32 is fixedly disposed at the bottom of the sliding groove 17, and the other end of the threaded rod 32 extends out of the connecting frame 31 through the circular hole in the center of the guide groove 18. The nut 33 is threadedly connected to the threaded rod 32, allowing the nut 33 to move along the axis of the threaded rod 32 when rotating. The pressing plate 34 is disposed on the nut 33. Between the connecting frame 31 and the connecting rod 36, when the nut 33 moves toward the connecting frame 31, the nut 33 can apply pressure to the extrusion plate 34, causing the extrusion plate 34 to move toward the connecting frame 31 along the axis of the threaded rod 32. The two ends of the connecting rod 36 are rotatably connected to the extrusion plate 34 and the slider 35, respectively. When the extrusion plate 34 moves closer to the connecting frame 31, the end of the connecting rod 36 rotatably connected to the extrusion plate 34 moves closer to the connecting frame 31 simultaneously. The included angle between the connecting rod 36 and the connecting frame 31 gradually decreases. The end of the connecting rod 36 rotatably connected to the slider 35 drives the slider 35 to move away from the threaded rod 32 along the slide groove 17. The sliding of slider 35 causes the energy-dissipating steel rod 37 to move, allowing the operator to rotate nut 33 to slide the rod. The installation and removal of the transverse wave reduction assembly 3 is achieved by the up-and-down sliding of the energy-dissipating steel rod 37 on the support base 13. Sliding slider 35 is cylindrical, with a threaded hole at the end furthest from connecting rod 36. Energy-dissipating steel rod 37 is also cylindrical, with fixed ends and a necked section in the middle. The end of energy-dissipating steel rod 37 closest to slider 35 is threaded, and the rod is threadedly fixedly connected to slider 35. The energy-dissipating steel bar 37 is made of duplex steel. The bidirectional steel material of the energy-dissipating steel bar 37 can be a bidirectional structure of ferrite and martensite, which makes the energy-dissipating steel bar 37 have both high strength and high ductility. The energy dissipation principle of the energy-dissipating steel bar 37 is the prior art in this application embodiment. Therefore, the energy dissipation principle of the energy-dissipating steel bar 37 is not specifically described in this application embodiment. The spring 38 is sleeved on the end of the threaded rod 32 near the connecting frame 31. The spring 38 extends to the outside of the connecting frame 31 through the circular hole on the guide groove 18. The spring 38 can provide support and reaction force to the pressing plate 34 and the nut 33, so that the nut 33 is more stably fixed to the pressing plate 34.

[0061] In practical use, when an earthquake occurs, the seismic shear wave is transmitted to the prefabricated building, causing it to sway horizontally. The necked end of the energy-dissipating steel bar 37 undergoes material yielding or plastic deformation, absorbing the kinetic energy of the prefabricated building and maintaining its stability, thus achieving the purpose of vibration reduction. After the earthquake, workers enter the installation space of the connecting equipment between the prefabricated buildings. They rotate the nut 33, moving it away from the connecting frame 31. Under the action of the spring 38, the pressing plate 34 moves away from the connecting frame 31 along the axis of the threaded rod 32. The pressing plate 34 drives the connecting rod 36 from an inclined state to a vertical state, gradually increasing the angle between the connecting rod 36 and the connecting frame 31. The connecting rod 36 then drives the slider 35 to slide towards the center of the connecting frame 31. The sliding block 35 drives the energy-consuming steel rod 37 to move away from the support base 13, allowing the worker to remove the transverse wave reduction assembly 3 from the support base 13. The worker rotates the energy-consuming steel rod 37 to disengage it from the slider 35. The worker then installs the unused energy-consuming steel rod 37 onto the slider 35. The worker places the transverse wave reduction assembly 3, after replacing the energy-consuming steel rod 37, in a fixed position. By rotating the nut 33, the extrusion plate 34 moves towards the connecting frame 31. The extrusion plate 34 moves the connecting rod 36, which in turn moves the slider 35 and the energy-consuming steel rod 37 away from the connecting frame 31. Finally, they enter the support hole 16 of the support base 13 and abut against the bottom of the support hole 16, enabling the worker to quickly assemble and maintain the connecting equipment, which is convenient for large-scale promotion in ordinary prefabricated buildings.

[0062] The implementation principle of this application is as follows: When an earthquake occurs, the longitudinal wave reduction component 2 absorbs the energy generated by the longitudinal wave through the elastic deformation of the disc spring assembly 22, and the transverse wave reduction component 3 absorbs the energy generated by the transverse wave by preferentially causing the energy-dissipating steel rod 37 to undergo material yielding or plastic deformation, thereby reducing the impact of the transverse and longitudinal waves on the prefabricated building; after the earthquake, workers enter the installation space of the connecting equipment between the prefabricated buildings, and the workers rotate the nut 33 so that the extrusion plate 34 moves away from the connecting frame 31 along the axis of the threaded steel under the action of the spring 38, driving the connecting rod 36 to move, thereby causing the slider 35 and the energy-dissipating steel rod 36 to move. The steel rod 37 slides toward the center of the connecting frame 31, allowing the operator to quickly remove the transverse wave reduction component 3 from the support base 13. The operator rotates the energy-dissipating steel rod 37 to disengage it from the slider 35. After replacing the energy-dissipating steel rod 37, the operator places the transverse wave reduction component 3 in a fixed position and rotates the nut 33. The movement of the nut 33 drives the extrusion plate 34 to move toward the connecting frame 31. Through a series of transmissions, the energy-dissipating steel rod 37 enters the support hole 16 of the support base 13 and abuts against the bottom of the support hole 16, enabling the operator to quickly assemble and maintain the connecting equipment, which is convenient for large-scale promotion in ordinary prefabricated buildings.
