Description

Technical Field

[0001] The present invention relates to the technical field of vibration prevention of assembled building structures, and more particularly to a flexible buffer connection device for prefabricated building components. Background Art

[0002] In the field of prefabricated construction, the transportation of prefabricated components is a critical step in the construction process. However, damage caused by impact and vibration during transportation has long been a serious constraint on the industry's development. According to industry statistics, the damage rate of prefabricated components using traditional transportation methods is as high as 10% to 15%, with over 80% of this damage occurring at joints, edges, and surfaces, severely impacting construction quality and project progress.

[0003] At present, when transporting or installing prefabricated building components of different heights, such as two prefabricated building walls and the prefabricated building window frames between them (of different heights) or the connection between two prefabricated building walls (flush in height), etc., there are differences in the heights of prefabricated walls and the connected components. Prefabricated building components are mainly fixed in the following ways during transportation: Chain / wire rope bundling: The wire rope is passed through the lifting ring or reserved hole of the component, and is tightened and fixed with a basket bolt; however, this method is rigid and lacks buffering capacity. It is easy to cause local damage to the component due to stress concentration during sudden braking or bumps; Steel clamp clamping: Channel steel, angle steel, etc. are welded into a frame, and both sides of the component are clamped by bolts or hydraulic devices; however The clamps are in hard contact with the components, and vibration is transmitted directly, which can easily cause cracks in corners or surface wear; temporary fixation by welding: direct welding between the embedded steel plate of the component and the transport frame, and cutting and removing it after transportation; however, the operation is cumbersome, and the heat of welding may damage the components, and secondary processing is required after disassembly, which is inefficient; traditional fixing methods are all rigid connections, which cannot effectively absorb the impact energy caused by road bumps, sudden braking or turning inertia, resulting in stress concentration inside the components, increasing the risk of damage. Long-term vibration will cause microcracks in the components to expand, reducing the durability of the structure, especially for components with decorative surface layers or precise interfaces. In view of this, we propose a flexible buffer connection device for prefabricated building components. Summary of the Invention

[0004] The purpose of the present invention is to provide a flexible buffer connection device for prefabricated building components to solve the technical problem that the connection parts of prefabricated wall components are easily damaged by impact and vibration during transportation and installation.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a flexible buffer connection device for prefabricated building components, comprising a prefabricated wall, a clamping connection mechanism arranged on one side of the prefabricated wall, a buffer assembly arranged on the left side of the clamping connection mechanism on the side of the prefabricated wall, and a limit assembly arranged on the right side of the clamping connection mechanism, wherein the clamping connection mechanism includes a clamping plate with a foldable structure located on one side of the prefabricated wall, and a clamping structure is symmetrically arranged on the right side of the clamping plate;

It is suitable for prefabricated building components with fragile surfaces and structures that need to be transported or installed in the air. When the clamping plate is folded, it can fix the upper half of large prefabricated building components, making it suitable for the transportation and installation of large prefabricated building components.

[0008] When the prefabricated building components are transported in mid-air, they turn and tilt to the left or right from a horizontal state due to inertia. When the prefabricated building components are in a horizontal state, the left pipe and the right pipe are in circulation, which can exert a stable supporting force on the prefabricated building components being transported in mid-air. When the prefabricated building components tilt to the left due to inertia, the left pipe is in circulation and the right pipe is not in circulation, exerting a lifting force on the prefabricated building components on the left side. When the prefabricated building components tilt to the right due to inertia, the right pipe is in circulation and the left pipe is not in circulation, exerting a downward pressure on the prefabricated building components on the right side. The present invention provides a foldable clamping plate at the connection of the prefabricated wall, which flexibly fits the connection interface of the fixed component when unfolded. The transition cylinder and the spherical valve body in the buffer assembly are linked with the building structure piping system to intelligently adjust the airflow path according to the component state, effectively absorb the impact energy of the building structure connection part, and significantly improve the connection reliability and seismic performance of the prefabricated building structure.

[0041] like Figure 1 、 Figure 5-Figure 6 and Figure 14-15 As shown, the present invention relates to a flexible buffer connection device for prefabricated building components, including a prefabricated wall 1, a mounting plate 11 arranged on one side of the prefabricated wall 1, a clamping connection mechanism 2 arranged on one side of the prefabricated wall 1, a buffer component 3 arranged on one side of the prefabricated wall 1 and located on the left side of the clamping connection mechanism 2, and a limiting component 4 arranged on the right side of the clamping connection mechanism 2.

[0042] The clamping connection mechanism 2 includes a clamping plate 21 located on one side of the prefabricated wall 1. The clamping plate 21 is composed of a long plate 211 and an end plate 212, and the long plate 211 is hinged to the end plate 212. A first motor 22 is fixedly connected to one side of the long plate 211, and the output shaft of the first motor 22 corresponds to the horizontal axis of the hinge of the end plate 212. A cam 23 is fixedly connected to the output end of the first motor 22, and the cam 23 is movably sleeved on the surface of the convex block on the end plate 212. The pneumatic slider 24 is slidably connected to the hole in the clamping plate 21 in a symmetrical structure. Each pneumatic slider 24 is fixed on one side. A mounting plate 241 is fixedly connected thereto, and each pneumatic slider 24 is symmetrically connected to the mounting plate 241 and is rotatably connected to a support plate 25. A slot 251 is arranged on the upper surface of each support plate 25, and a torsion spring 26 is movably sleeved on the end of each support plate 25, and one end of the torsion spring 26 is fixedly connected to the pneumatic slider 24. A bolt 27 is fixedly connected to one side of each pneumatic slider 24, and a resist plate 28 is movably sleeved on the surface of each bolt 27. A nut 281 is rotatably connected to one side of each resist plate 28, and the nut 281 is threadably adapted to the bolt 27.

[0043] It is worth noting that by arranging the clamping groove 251 on the surface of the support plate 25, when it contacts the lower surface of the prefabricated building component, the support plate 25 rotates axially due to the action of gravity, clamping the lower surface of the prefabricated building component and enhancing friction.

[0044] Specifically, when the foldable clamping plate 21 is unfolded, the clamping structure is driven by gas, so that it fits and fixes with the upper and lower surfaces of the prefabricated building components. It is suitable for prefabricated building components whose surfaces and structures are fragile and need to be transported in mid-air; when the clamping plate 21 is folded, the clamping structure located below the clamping plate 21 is folded, so that the clamping structure located above the clamping plate 21 fits with the upper surface of the large prefabricated component, so that the upper half of the large prefabricated building component is fixed. It is suitable for the transportation and fixation of large prefabricated building components.

[0045] The flexible buffer connection device for building prefabricated components of the present invention achieves efficient protection and scene adaptation through multi-structure collaborative innovation. The hydraulically driven prefabricated wall 1 ensures precise control. The foldable clamping connection mechanism 2 can use the pneumatic slider 24 and the card slot 251 to flexibly and non-contact fix the fragile suspended components through the expansion or folding mode to avoid rigid damage, and can also achieve strong load-bearing fixation of heavy components through the upper surface mounting plate 241 and the hydraulic clamp 44.

[0046] like Figure 2-Figure 3 and Figure 7-13 As shown, the buffer assembly 3 includes a fixing frame 31, which is fixedly connected to the right side of the mounting plate 11, and a sealing cylinder 32 is hinged on the right side of the fixing frame 31. A hexagonal column 33 is fixedly connected to the left side of the clamping plate 21, and the hexagonal column 33 is slidingly sealed and adapted inside the sealing cylinder 32. The surface of the hexagonal column 33 is arranged in a linear array with a plurality of upper notches 331 and lower notches 332. The surface of the sealing cylinder 32 is connected to a transition cylinder 34, and the surface of the transition cylinder 34 is arranged with a left pipe 341 and a right pipe 342, and the left pipe 341 is connected to the surface of the sealing cylinder 32 located at the upper notch 331, and the right pipe 342 is connected to the surface of the sealing cylinder 32 located at the lower notch 332. A spherical valve body 35 is fixedly sleeved inside the transition cylinder 34. The surface of the spherical valve body 35 is symmetrically structured with two flow holes 351, and the two flow holes 351 are respectively connected to the left pipe 341 and the right pipe 342. A switch valve 36 is rotatably sleeved inside the spherical valve body 35. Two valve plates 361 are arranged diagonally on the surface of the switch valve 36, and the valve plates 361 are sealed and adapted to the flow holes 351. One side of the switch valve 36 is fixedly connected to the counterweight block 37 located on the outside of the transition cylinder 34 through an insertion rod. A cylinder 38 is fixedly connected to the inner wall of the mounting plate 11. The cylinder 38 is connected to the spherical valve body 35 through a hose 381, and the hose 381 passes through the fixing frame 31.

[0047] Specifically, when the prefabricated building components are transported in mid-air and turn, the prefabricated building components tilt to the left or right from a horizontal state due to inertia. When the prefabricated building components are in a horizontal state, the two flow holes 351 on the spherical valve body 35 are open, causing the left pipe 341 and the right pipe 342 to respectively apply a stable supporting force to the hexagonal column 33, so that it can be stably suspended in the air; when the prefabricated building components tilt to the left due to inertia, one of the flow holes 351 is open, causing the left pipe 341 corresponding to the position of the upper notch 331 to flow, while the right pipe 342 does not flow, thereby applying an upward supporting force to the prefabricated building components tilted to the left, thereby stabilizing it; when the prefabricated building components tilt to the right due to inertia, the right pipe 342 corresponding to the position of the lower notch 332 to flow, while the left pipe 341 does not flow, thereby applying a downward force to the prefabricated building components tilted to the right, thereby correcting the tilting prefabricated building components.

[0048] The present invention provides uniform support in a horizontal state through the linkage of the buffer component 3 based on the hexagonal column 33, the spherical valve body 35 and the counterweight block 37. When the component tilts due to the inertia of the vehicle turning, the air flow path is automatically switched, and a reverse lifting force or downward pressure is applied to the tilted side to absorb energy and achieve a flexible buffering effect.

[0049] like Figure 4-Figure 5 As shown, the limiting assembly 4 includes a fixed plate 41 fixedly connected to the right side of the clamping plate 21, a hydraulic rod 42 fixedly connected to the right side of the clamping plate 21, and a plurality of multi-link modules 43 are arranged in a circular array at the output end of the hydraulic rod 42. A clamping claw 44 is arranged at the output end of each multi-link module 43, and a groove 441 is arranged on the surface of the clamping claw 44.

[0050] It is worth noting that the limiting component 4 is a clamping component of existing conventional technology, which will not be described in detail here. When the several clamping jaws 44 are opened, they fit with the surface of the prefabricated building component, among which the groove 441 fits with the surface of the prefabricated building component to increase friction.

[0051] Working principle: This embodiment provides a flexible buffer connection device for prefabricated building components. When the prefabricated building components are suspended for transportation and installation (the installation heights of the prefabricated building components are different), the prefabricated building components are first placed between two mounting plates 241 by an external lifting device, and then the mounting plates 241 are adjusted by an external control system so that they fit and are fixed to the upper surface of the prefabricated building components. During transportation, when the prefabricated building components are in a horizontal state, the cylinder 38 is operated by the external control system, and gas is delivered through the hose 381, causing the two flow holes 351 on the spherical valve body 35 to flow, so that the left pipe 341 and the right pipe 342 flow, and the upper notch 331 and the lower notch 332 are respectively connected through the left pipe 341 and the right pipe 342. Gas is supplied, so that the prefabricated building components can be stable during transportation. When the transport vehicle turns, the building components tilt to one side due to inertia. At this time, under the action of the weight of the counterweight block 37 itself, the switch valve 36 rotates. When the prefabricated building component tilts to the left, one of the flow holes 351 on the left side of the prefabricated building component flows, so that the left pipe 341 corresponding to the position of the upper notch 331 flows, and the right pipe 342 does not flow, thereby applying a lifting force to the left side to achieve stability. On the right side, the right pipe 342 corresponding to the position of the lower notch 332 flows, and the left pipe 341 does not flow, thereby applying downward pressure to the prefabricated building component facing the right side, thereby correcting the tilting prefabricated building component and achieving a flexible buffering effect.

[0052] Fixed transportation (connecting prefabricated components at the same height): The first motor 22 is activated by an external circuit mechanism. The first motor 22 drives the cam 23 to cause the long plate 211 and the end plate 212 to fold and fit together, so that the upper mounting plate 241 fits and is fixed to the upper surface of the large prefabricated building component. The hydraulic rod 42 drives the multi-link module 43 to cause the clamping claw 44 to open and fit with one side of the prefabricated building component through the groove 441 to enhance friction. Among them, by fixing the upper half of the large prefabricated building component, the vehicle can suppress the tilt of the building component when turning, thereby achieving stability.

[0053] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
