Description

Technical Field

[0001] This invention belongs to the field of prefabricated building technology, specifically a connection structure for prefabricated building wall panels. Background Technology

[0002] Existing prefabricated wall panels can be commercially produced, with high on-site construction efficiency, low labor intensity, light weight, and a high degree of industrialization. They have advantages such as high degree of construction mechanization, short construction period, less on-site labor, less wet work, and less impact from seasonality.

[0003] Currently, when splicing and installing two sets of prefabricated wall panels, anchor rods or corner blocks with bolt assemblies are mostly used to fix the two sets of wall panels. Although the above connection methods are relatively strong, the installation and disassembly are inconvenient and require a lot of manual labor, resulting in low loading and unloading efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a connection structure for prefabricated building wall panels.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A connection structure for prefabricated building wall panels includes a wall panel, a flexible sealing element, a threaded connection assembly, and a threaded drive assembly. The threaded connector assembly is disposed on one side of the wall panel, and the other side of the wall panel has a socket for inserting the threaded connector assembly. The threaded drive assembly is rotatably disposed inside the wall panel and can cooperate with the threaded plug assembly. When the threaded drive assembly rotates in one direction, it can drive the threaded insertion assembly to move inward into the wall panel. When the threaded drive assembly rotates in another direction, it can drive the threaded insertion assembly to move outward from the wall panel. The flexible sealing element is disposed on the edge of the side wall of the wall panel and is used to seal the gap between two adjacent sets of wall panels; The threaded plug-in assembly and the threaded drive assembly are provided in several sets corresponding to each other on one side of the wall panel. A square column is fixedly installed on one side of the wall panel. One end of the screw extends into the inside of the square column and is fixedly connected to a square limiting block. The screw can drive the square limiting block to move horizontally inside the square column. Based on the setting of the square column and the square limiting block, it can prevent the remaining threaded plug-in assembly and threaded drive assembly from seizing each other when one set of threaded plug-in assembly and threaded drive assembly is disassembled, thus ensuring the smooth removal of the two sets of wall panels.

[0006] As a further improvement of the present invention: the threaded connector assembly includes a screw, one end of which is connected to the side wall of the wall panel. The threaded drive assembly includes a ring, a threaded sleeve, a handle, a first limiting assembly, a second limiting assembly, and an adjusting assembly. Both the ring sleeve and the threaded sleeve are disposed inside the wall panel. The ring sleeve is movably fitted onto the outside of the threaded sleeve. The outer wall of the threaded sleeve is provided with a plurality of toothed plates. One end of the handle extends into the wall panel and is fixedly connected to the ring sleeve. The first limiting component and the second limiting component are hinged at one end to the inner wall of the ring, and the other end can extend to the space between two adjacent sets of teeth. The adjusting component is movably engaged with the handle to adjust the angle of the first limiting component and the second limiting component.

[0007] As a further improvement of the present invention: the adjusting assembly includes a push-pull rod, a first support rod, and a second support rod. The first limiting component and the second limiting component are arranged in a figure-eight shape and are opposite to each other. One end of the push-pull rod passes through the handle and extends between the first limiting component and the second limiting component. A wedge-shaped block is fixedly provided on the side of the first limiting component facing the second limiting component. The first support rod is fixedly disposed on the side of the push-pull rod facing the first limiting component and is in contact with the wedge block. The second support rod is fixedly disposed on the side of the push-pull rod facing the second limiting component and is in contact with the second limiting component. The first limiting component and the second limiting component are both connected to the inner wall of the ring sleeve through elastic components.

[0008] As a further improvement of the present invention: both the first limiting component and the second limiting component are rods with V-shaped or hook-shaped structures.

[0009] As a further improvement of the present invention: a storage groove adapted to the handle is provided on one side of the wall panel.

[0010] As a further improvement of the present invention: a square column is fixedly provided on one side of the wall panel, and one end of the screw extends into the interior of the square column and is fixedly connected to a square limiting block.

[0011] As a further improvement of the present invention: the square limiting block is also connected to the inner wall of the square column by an elastic support member.

[0012] Compared with the prior art, the beneficial effects of the present invention are: In this embodiment of the invention, during installation, two sets of wall panels can be arranged sequentially. The threaded plug-in assembly on one side of one set of wall panels is inserted into the plug hole on one side of the other set of wall panels. Then, the threaded drive assembly is rotated in one direction, causing the threaded plug-in assembly to move into one set of wall panels, thereby bringing the two sets of wall panels closer together and connecting them. At this time, a flexible sealing element is used to seal the gap between the two sets of wall panels, achieving a tight fit between them. During disassembly, the threaded drive assembly can be rotated in the other direction, causing the threaded plug-in assembly to move outward from the currently inserted wall panel, separating the two sets of wall panels and achieving disassembly. Compared with the prior art, this method enables rapid installation and removal of two sets of wall panels, offering advantages such as convenient operation and high installation and removal efficiency.

Detailed Implementation

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0016] Please see Figure 1 and Figure 3This embodiment provides a connection structure for prefabricated building wall panels, including a wall panel 10, a flexible sealing element 20, a threaded insertion assembly 30, and a threaded drive assembly 40. The threaded insertion assembly 30 is disposed on one side of the wall panel 10, and the other side of the wall panel 10 has an insertion hole 101 for the threaded insertion assembly 30 to be inserted. The threaded drive assembly 40 is rotatably disposed inside the wall panel 10 and can cooperate with the threaded insertion assembly 30. When the threaded drive assembly 40 rotates in one direction, it can drive the threaded insertion assembly 30 to move inward into the wall panel 10. When the threaded drive assembly 40 rotates in the other direction, it can drive the threaded insertion assembly 30 to move outward from the wall panel 10. The flexible sealing element 20 is disposed on the edge of the side wall of the wall panel 10 and is used to seal the gap between two adjacent sets of wall panels 10.

[0017] During installation, two sets of wall panels 10 can be arranged sequentially. The threaded connector 30 on one side of one set of wall panels 10 is inserted into the insertion hole 101 on one side of the other set of wall panels 10. Then, the threaded drive assembly 40 is rotated in one direction, which drives the threaded connector 30 to move into one set of wall panels 10, thereby bringing the two sets of wall panels 10 closer together and connecting them. At this time, the flexible seal 20 is used to seal the gap between the two sets of wall panels 10, achieving a tight fit between them. During disassembly, the threaded drive assembly 40 can be rotated in the other direction, which drives the threaded connector 30 to move outward from the currently inserted wall panel 10, separating the two sets of wall panels 10 and achieving disassembly.

[0018] Please see Figure 2 and Figure 3 In one embodiment, the threaded insertion assembly 30 includes a screw 303, one end of which is connected to the side wall of the wall panel 10. The threaded drive assembly 40 includes a ring 401, a threaded sleeve 403, a handle 404, a first limiting assembly 50, a second limiting assembly 60, and an adjusting assembly 80. The ring 401 and the threaded sleeve 403 are both disposed inside the wall panel 10. The ring 401 is movably sleeved on the outside of the threaded sleeve 403. The outer wall of the threaded sleeve 403 is provided with a plurality of toothed plates 402. One end of the handle 404 extends into the wall panel 10 and is fixedly connected to the ring 401. One end of the first limiting assembly 50 and the second limiting assembly 60 is hinged to the inner wall of the ring 401, and the other end can extend between two adjacent sets of toothed plates 402. The adjusting assembly 80 is movably engaged with the handle 404 to adjust the angle of the first limiting assembly 50 and the second limiting assembly 60.

[0019] During installation, the screw 303 on one side of one set of wall panels 10 is inserted into the insertion hole 101 on one side of another set of wall panels 10. Then, the handle 404 is rotated back and forth, causing the ring sleeve 401 to rotate back and forth. At this time, the angle between the first limiting component 50 and the second limiting component 60 is adjusted by the adjusting component 80, so that the end of the first limiting component 50 away from the inner wall of the ring sleeve 401 extends between the two adjacent sets of toothed plates 402, and the end of the second limiting component 60 away from the inner wall of the ring sleeve 401 moves away from the two adjacent sets of toothed plates 402. During the reciprocating rotation of the ring sleeve 401, a "ratchet and pawl" structure is formed between the first limiting component 50 and the toothed plates 402, thereby causing the threaded sleeve 403 to rotate intermittently. The screw 303 moves inward toward the wall panel 10, thus fixing the two sets of wall panels 10 together. During disassembly, the angle between the first limiting component 50 and the second limiting component 60 is adjusted by the adjusting component 80, so that the end of the first limiting component 50 away from the inner wall of the ring 401 moves away from the two adjacent sets of toothed plates 402, and the end of the second limiting component 60 away from the inner wall of the ring 401 extends to the two adjacent sets of toothed plates 402. The second limiting component 60 and the toothed plates 402 form a structure similar to a "ratchet and pawl". Then, the handle 404 is rotated back and forth again. The handle 404 drives the threaded sleeve 403 to rotate intermittently in the opposite direction through the second limiting component 60, thereby driving the screw 303 to move outward toward the wall panel 10, so as to separate the two sets of wall panels 10 from each other.

[0020] Please see Figure 3 In one embodiment, the adjusting component 80 includes a push-pull rod 804, a first support rod 802, and a second support rod 803. The first limiting component 50 and the second limiting component 60 are arranged in a V-shape and are opposite to each other. One end of the push-pull rod 804 passes through the handle 404 and extends between the first limiting component 50 and the second limiting component 60. A wedge block 801 is fixedly disposed on the side of the first limiting component 50 facing the second limiting component 60. The first support rod 802 is fixedly disposed on the side of the push-pull rod 804 facing the first limiting component 50 and is in contact with the wedge block 801. The second support rod 803 is fixedly disposed on the side of the push-pull rod 804 facing the second limiting component 60 and is in contact with the second limiting component 60. The first limiting component 50 and the second limiting component 60 are both connected to the inner wall of the ring 401 through an elastic component 70.

[0021] During installation, the elastic component 70 provides elastic support to the first limiting component 50, allowing one end of the first limiting component 50 to extend between two adjacent sets of toothed plates 402. At this time, the second support rod 803 acts on one side of the second limiting component 60, causing one end of the second limiting component 60 to separate from the two sets of toothed plates 402. By reciprocatingly rotating the handle 404, the ring sleeve 401 and the first limiting component 50 are rotated. The first limiting component 50 pushes the toothed plates 402, thereby driving the threaded sleeve 403 to rotate. Through the threaded engagement between the threaded sleeve 403 and the screw 303, the screw 303 drives the corresponding wall panel 10 to move, achieving the installation and fixation between the two sets of wall panels 10. During disassembly, the push-pull rod 804 can be pushed, which drives the first support rod 802 and the second support rod 803 to rotate. When rod 803 moves inward toward the ring 401, the first support rod 802 acts on the wedge block 801 to drive the first limiting component 50 to rotate, causing one end of the first limiting component 50 to separate from the two adjacent sets of toothed plates 402. When the second support rod 803 moves, the corresponding elastic component 70 can drive the second limiting component 60 to rotate, causing one end of the second limiting component 60 to extend between the two adjacent sets of toothed plates 402. By reciprocatingly rotating the handle 404, the ring 401 and the second limiting component 60 are driven to rotate. The second limiting component 60 pushes the toothed plates 402 to drive the threaded sleeve 403 to rotate in the opposite direction. Through the threaded engagement between the threaded sleeve 403 and the screw 303, the screw 303 moves outward toward the threaded sleeve 403, realizing the separation between the two sets of wall panels 10.

[0022] In one embodiment, both the first limiting component 50 and the second limiting component 60 are rods with a V-shaped structure or a hook-shaped structure.

[0023] Please see Figure 4 In one embodiment, a storage slot 102 adapted to the handle 404 is provided on one side of the wall panel 10.

[0024] During loading and unloading, the handle 404 can be rotated out of the storage slot 102, and then the handle 404 can be rotated back and forth within a certain range. Through the action of the first limiting component 50 and the second limiting component 60, the threaded sleeve 403 will be rotated accordingly. After loading and unloading, the handle 404 can be rotated into the storage slot 102 to realize the storage of the handle 404.

[0025] Please see Figure 1 and Figure 2In one embodiment, to improve the stability of the connection between the two sets of wall panels 10, several sets of threaded insertion components 30 and threaded drive components 40 are provided correspondingly on one side of each wall panel 10. Since the connection between the two sets of wall panels 10 is achieved by the threaded sleeve 403 driving the screw 303 to move linearly, based on the several sets of threaded insertion components 30 and threaded drive components 40, to ensure smooth disassembly, a square column 301 is fixedly provided on one side of each wall panel 10. One end of the screw 303 extends into the square column 301 and is fixedly connected to a square limiting block 302. When one set of threaded sleeves 403 drives the corresponding screw 303 to move outward, the screw 303 can drive the square limiting block 302 to move horizontally inside the square column 301 until the screw 303 is completely removed from the inside of the threaded sleeve 403. Then the remaining threaded sleeves 403 and screws 303 can be disassembled. By setting up the square column 301 and the square limiting block 302, it is possible to avoid the remaining threaded plug-in components 30 and threaded drive components 40 from seizing each other when disassembling one set of threaded plug-in components 30 and threaded drive components 40, thus ensuring the smooth disassembly of the two sets of wall panels 10.

[0026] Please see Figure 2 In one embodiment, the square limiting block 302 and the inner wall of the square column 301 are connected by an elastic support member. The elastic support member provides elastic support to the square limiting block 302, so that when the screw 303 is inserted into the insertion hole 101, the screw 303 can smoothly engage with the threaded sleeve 403. During the subsequent rotation of the threaded sleeve 403, the screw 303 is smoothly driven to move into the threaded sleeve 403, thereby realizing the smooth installation between the two sets of wall panels 10.

[0027] In one embodiment, the elastic component 70 and the elastic support can be springs or metal sheets, which are not limited here. The flexible seal 20 can be a rubber sheet or a plastic sheet, which are not limited here.

[0028] In this embodiment of the invention, during installation, two sets of wall panels 10 can be arranged sequentially. The threaded insertion component 30 on one side of one set of wall panels 10 is inserted into the insertion hole 101 on one side of the other set of wall panels 10. Then, the threaded drive component 40 is rotated in one direction, causing the threaded insertion component 30 to move into one set of wall panels 10, thereby bringing the two sets of wall panels 10 closer together and achieving a connection between them. At this time, the flexible sealing element 20 is used to seal the gap between the two sets of wall panels 10, achieving a tight fit between them. During disassembly, the threaded drive component 40 can be rotated in the other direction, thereby moving the threaded insertion component 30 outward from the currently inserted wall panel 10, causing the two sets of wall panels 10 to separate from each other and achieving disassembly. Compared with the prior art, this method enables quick installation and removal of the two sets of wall panels 10, and has the advantages of convenient operation and high installation and removal efficiency.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
