Description

Technical Field

[0001] This application relates to the field of building connection technology, and in particular to a prefabricated wall panel connection structure and installation method. Background Technology

[0002] In the construction industry, prefabricated buildings have developed rapidly in recent years. They have many advantages such as fast construction speed, easy quality control, energy saving and environmental protection, which have greatly promoted the industrialization process of the construction industry. As an important part of prefabricated buildings, the performance of the connection structure of prefabricated wall panels directly affects the stability and safety of the entire building. Reasonable and effective wall panel connection methods can ensure reliable connection between wall panels, improve the integrity of the building structure, reduce safety hazards caused by weak connections, and also help improve construction efficiency and reduce construction costs.

[0003] In existing technologies, there are several common methods for connecting prefabricated wall panels. One method is welding, which involves welding the metal connectors on the wall panels together to provide strong connection strength. Another common method is bolting, which involves pre-drilling holes in the wall panels and then using bolts to fix them in place. Bolting is relatively easy to install. Another method is adhesive bonding, which involves applying adhesive to the joint surfaces of the wall panels and using the adhesive's stickiness to connect them.

[0004] Regarding the aforementioned technologies, the inventors believe that existing connectors are usually rigid fixed connections. If it is necessary to adjust the installation angle between wall panels according to the actual needs of the construction site, the connectors usually need to be removed or replaced, resulting in low applicability of the wall panel connectors. Summary of the Invention

[0005] To address the issue of limited applicability of wall panel connectors when adjusting the installation angle between wall panels according to the construction site, this application provides a prefabricated wall panel connection structure and installation method.

[0006] The technical solution provided in this application for a prefabricated wall panel connection structure and installation method is as follows: A prefabricated wall panel connection structure includes a first connecting part and a second connecting part for cooperating with the first connecting part. The first connecting part includes a first fixing member for connecting the wall panel, a rotating shaft rotatably installed inside the first fixing member, a pin assembly fixedly installed at the end of the first fixing member for locking the position of the rotating shaft, a connecting box fixedly installed on one side of the rotating shaft and having two chambers of different sizes, a limiting cylinder slidably installed in the large chamber of the connecting box along the height direction of the wall panel, and a threaded rod rotatably installed in the large chamber of the connecting box. A lock is connected to the outside of the threaded rod for driving the limiting cylinder to slide and locking its position. The connecting box contains a drive assembly for driving the threaded rod and a transmission assembly for driving the pin assembly to move upward and lock the rotating shaft. A pressing block for pressing the transmission assembly is rotatably mounted at the bottom of the limiting cylinder. A synchronization assembly is provided between the pressing block and the threaded rod. When the limiting cylinder slides down to a set position, the synchronization assembly drives the pressing block and the threaded rod to rotate synchronously, causing the pressing block to press the transmission assembly and drive the pin assembly to lock. The second connecting part includes a second fixing member for connecting to another wall panel and a limiting slot fixedly installed on one side of the second fixing member for insertion of the limiting cylinder.

[0007] By adopting the above technical solution, the connection of two sets of prefabricated wall panels is achieved by setting a first connecting part and a second connecting part. The wall panels are connected by a first fixing part and a second fixing part, respectively. The angle of connection between the two sets of wall panels is adjusted by a rotating shaft, and the position of the rotating shaft is locked by a pin assembly. This improves the applicability of the device for wall panel connection under different conditions. The drive assembly drives the threaded rod to rotate and cooperates with the locking assembly to drive the limiting cylinder to slide and lock its position, thereby making the two sets of wall panels firmly connected. The synchronization assembly can make the extrusion block and the threaded rod rotate synchronously when the limiting cylinder slides down to the set position, so that the extrusion block extrudes the transmission assembly to lock the pin assembly. The locking of the wall panel connection structure and the locking of the connection angle can be completed by simply rotating the drive assembly, which simplifies the wall panel connection steps to a certain extent and improves the installation efficiency of workers when connecting wall panels.

[0008] Optionally, the locking assembly includes a threaded block fixedly installed on the top of the limiting cylinder and threadedly engaged with the threaded rod, a sliding block fixedly installed on the outside of the threaded block, and a limiting groove provided on the inner wall of the connecting box for the sliding block to slide.

[0009] By adopting the above technical solution, the locking component is limited, and the rotation of the limiting cylinder is driven by the engagement of the threaded block and the threaded rod. By setting a sliding block to slide in the limiting groove, the sliding of the limiting cylinder is guided and limited, ensuring that the limiting cylinder slides stably in the set direction, so that the limiting cylinder can be accurately inserted into the limiting slot. At the same time, the self-locking property of the threaded block and the threaded rod is used to improve the vibration resistance of the connection, and to a certain extent improve the safety of the device during long-term use.

[0010] Optionally, the pin assembly includes a pin disc fixedly installed at the end of the first fixing member, a pin rod slidably installed inside the small cavity of the connecting box for inserting the pin disc, and a return spring sleeved on the outside of the pin rod for resetting the pin rod.

[0011] By adopting the above technical solution, the pin assembly is limited, and the pin rod slides inside the small cavity of the connecting box and inserts into the pin plate, thereby locking the position of the rotating shaft; by setting a reset spring, the pin rod automatically resets when no force is applied, thereby unlocking the rotating shaft, improving the convenience of use and adjustment of the prefabricated wall panel connection structure.

[0012] Optionally, the drive assembly includes a drive worm gear fixedly mounted on the outside of the threaded rod, a drive worm for cooperating with the worm gear, and a drive handle mounted on the end of the drive worm.

[0013] By adopting the above technical solution, the drive component is limited, and the threaded rod is driven to rotate by the cooperation of the drive worm wheel and the drive worm, thereby controlling the sliding of the limiting cylinder and locking its position. At the same time, by utilizing the self-locking properties of the drive worm wheel and the drive worm, the reliability of the wall panel connection is improved to a certain extent.

[0014] Optionally, the transmission assembly includes an inclined block that is slidably installed inside the small cavity of the connecting box along the height direction of the wall panel, a pusher that abuts against the inclined surface of the inclined block and is slidably installed on the inner wall of the connecting box along the length direction of the wall panel, and the bottom ends of the pin rod and the reset spring are both fixedly installed on the top surface of the inclined block.

[0015] By adopting the above technical solution, the transmission components are limited. By setting an inclined block that slides along the height direction of the wall panel and a pushing component that slides along the length direction of the wall panel, the components are subjected to pressure from the pressing block to transmit corresponding displacement. The inclined surface of the inclined block changes the direction of force transmission, thereby driving the pin rod to move and insert into the pin plate to lock the rotating shaft. Furthermore, the setting of the return spring can reset the pin rod when it is not being pressed. No manual step-by-step operation is required, avoiding the failure of locking due to forgetting steps in manual operation, thus improving the reliability and convenience of wall panel installation.

[0016] Optionally, the synchronization component includes a positioning platform fixedly installed on the end face of the drive worm gear, a positioning rod fixedly installed on the bottom end of the extrusion block, and a positioning hole provided on the end face of the positioning platform for the positioning rod to be inserted.

[0017] By adopting the above technical solution, and by setting a positioning platform, positioning rod and positioning hole, when the limiting cylinder slides down to the set position, the positioning rod is inserted into the positioning hole, driving the extrusion block and the threaded rod to rotate synchronously, thereby causing the extrusion block to extrude the transmission component, driving the pin component to move up and lock the rotating shaft, thereby locking the position of the rotating shaft and ensuring the stability and reliability of the prefabricated wall panel connection structure.

[0018] Optionally, a compression rod slides inside the limiting cylinder, a compression spring is provided at the top of the compression rod, a rotating ring is fixedly installed at the bottom of the compression rod, and the extrusion block is fixedly installed at the bottom of the rotating ring.

[0019] By adopting the above technical solution, the compression spring provides displacement distance for the limiting cylinder to slide down when locking the rotating shaft. At the same time, when the limiting cylinder slides down and inserts into the limiting slot, if there is a slight angular deviation, the compression rod can slide upward relative to the limiting cylinder and compress the compression spring, thereby avoiding rigid collision and damage between the extrusion block and the positioning table. When the positioning table rotates to the positioning hole and positioning rod position and realigns, the extrusion block and positioning table can rotate synchronously, so that the limiting cylinder can still maintain reliable contact with the transmission component when it reaches the set position, thus improving the installation fault tolerance.

[0020] Optionally, the bottom end of the limiting cylinder is provided with a tapered guide portion, and the end of the positioning rod is provided with a circular guide portion.

[0021] By adopting the above technical solution, the shape of the limiting cylinder is limited, and a tapered guide and a circular guide are respectively set at the bottom of the limiting cylinder and the positioning rod. This reduces the resistance of the limiting cylinder when it is inserted into the limiting slot. At the same time, it facilitates the insertion of the positioning rod into the positioning hole of the positioning table and reduces the sliding friction of the positioning rod on the top surface of the positioning table when the positioning rod and the positioning hole are misaligned. This improves the convenience and accuracy of assembly to a certain extent.

[0022] Optionally, both the first connecting part and the second connecting part are provided with four sets of mounting plates, and each set of mounting plates has two sets of mounting through holes.

[0023] By adopting the above technical solution, the structure of the first connecting part and the second connecting part is defined. By setting four sets of mounting plates and opening two sets of mounting through holes in each set of mounting plates, it is convenient to fix the first connecting part and the second connecting part to the corresponding wall panel through the mounting plates and mounting through holes, thus providing convenience for the installation of the prefabricated wall panel connection structure.

[0024] A prefabricated wall panel installation method based on the above-mentioned prefabricated wall panel connection structure includes the following steps: S1: The worker fixes the first connecting part to the wall panel to be connected using the first fastener, and fixes the second connecting part to another wall panel using the second fastener, and adjusts the two wall panels to the position to be spliced. S2: The operator adjusts the orientation of the connecting box by rotating the rotating shaft so that the large chamber opening of the connecting box is aligned with the limiting slot of the second connecting part, and moves the second wall plate so that the end of the limiting cylinder is opposite to the opening of the limiting slot; S3: The operator drives the threaded rod to rotate through the drive assembly, and the threaded rod drives the limiting cylinder to slide downward from the large cavity of the connecting box through the locking assembly until the end of the limiting cylinder is fully inserted into the limiting slot of the second connecting part, thus completing the initial mechanical locking between the first connecting part and the second connecting part; S4: When the limiting cylinder slides down to the set position, the synchronization component drives the extrusion block and the threaded rod to rotate synchronously, and the extrusion block extrudes the transmission component during the rotation; S5: After the transmission component is squeezed, it drives the pin component to move upward, so that the pin component inserts into and locks the rotating shaft, thereby fixing the circumferential position of the connecting box and the limiting cylinder, and completing the final connection between the first wall panel and the second wall panel.

[0025] In summary, this application includes at least one of the following beneficial technical effects: By setting a first connecting part and a second connecting part, the two sets of prefabricated wall panels are connected. The wall panels are connected by a first fastener and a second fastener respectively. The angle of connection between the two sets of wall panels is adjusted by a rotating shaft. The position of the rotating shaft is locked by a pin assembly, thereby improving the applicability of the device for wall panel connection under different conditions. The wall panel connection structure and connection angle can be locked by rotating the drive component, avoiding the forgetting of the locking step during manual operation, which would lead to the locking being invalid. This simplifies the wall panel connection process to a certain extent and improves the installation efficiency of workers when connecting wall panels. By setting a compression spring and a compression rod, a displacement distance is provided for the limiting cylinder to slide down when locking the rotating shaft. At the same time, when the limiting cylinder slides down and inserts into the limiting slot, if there is a slight angular deviation, the compression rod can slide upward relative to the limiting cylinder and squeeze the compression spring, thereby avoiding rigid collision between the squeezing block and the positioning table and causing damage. This ensures that the limiting cylinder can still maintain reliable contact with the transmission component when it reaches the set position, improving installation fault tolerance.

By cooperating with the rotating shaft 102, connecting box 104, limiting cylinder 105 and other components of the first connecting part 1 with the limiting slot 202 of the second connecting part 2, a multi-angle, adjustable connection between the wall panels is realized. During the connection process, the position of the limiting cylinder 105 is locked by the locking component 3, which simplifies the wall panel connection steps and improves the installation efficiency of workers when connecting wall panels. The position of the rotating shaft 102 is locked by the pin component 103, thereby improving the applicability of the device for wall panel connection under different conditions.

The first fixing member 101 securely connects the first connecting part 1 to the wall panel. The first fixing member 101 is a long, rectangular plate-like structure made of stainless steel to ensure it can withstand certain external forces. The first fixing member 101 is bolted to the wall panel. The rotating shaft 102 is rotatably mounted inside the first fixing member 101. The surface of the rotating shaft 102 is smooth to reduce friction during rotation. The rotating shaft 102 is connected to the first fixing member 101 via a bearing, thus ensuring... To ensure smooth rotation and facilitate worker rotation; the second connecting part 2 includes a second fixing member 201 and a limiting slot 202. The second fixing member 201 is used to connect another wall panel, and its structure and material are the same as the first fixing member 101. The limiting slot 202 is fixedly installed on one side of the second fixing member 201 for the insertion of the limiting cylinder 105, and its shape and size match the limiting cylinder 105; both the first connecting part 1 and the second connecting part 2 are provided with four sets of mounting plates 11, and each set of mounting plates 11 has two sets of mounting through holes 12. Through these mounting plates 11 and mounting through holes 12, the first connecting part 1 and the second connecting part 2 can be conveniently installed on the two wall panels respectively.

[0031] Reference Figure 4 The pin assembly 103 is fixedly installed at the end of the first fixing member 101 to lock the position of the rotating shaft 102. The pin assembly 103 includes a pin disc 1031, a pin rod 1032 and a return spring 1033. The pin disc 1031 is fixedly installed at the end of the first fixing member 101. The pin disc 1031 is disc-shaped and has multiple insertion holes on its surface for the insertion of the pin rod 1032. The pin rod 1032 is slidably installed inside the small cavity of the connecting box 104. It is a rod-shaped metal structure with a smooth end, which facilitates insertion into the insertion hole of the pin disc 1031. The return spring 1033 is sleeved on the outside of the pin rod 1032 and the other end of the return spring 1033 is fixedly installed on the top surface of the inclined block 501. When the pin rod 1032 is not under force, the return spring 1033 is released, thereby pushing the pin rod 1032 to return to its original position.

[0032] The connecting box 104 is fixedly installed on one side of the rotating shaft 102 and has two chambers of different sizes. The connecting box 104 is made of metal. The large chamber is used to install the limiting cylinder 105 and the threaded rod 106, and the small chamber is used to install the pin rod 1032 and the transmission assembly 5, etc.

[0033] Reference Figure 4 and Figure 5The limiting cylinder 105 is slidably installed in the large cavity of the connecting box 104 along the height direction of the wall panel. The limiting cylinder 105 is a hollow cylindrical shape and is made of metal. A compression rod 8 slides inside the limiting cylinder 105. A compression spring 9 is provided at the top of the compression rod 8. A rotating ring 10 is fixedly installed at the bottom of the compression rod 8. The squeezing block 6 is fixedly installed at the bottom of the rotating ring 10. During the sliding process, the limiting cylinder 105 buffers the squeezing block 6 and the positioning table 701 through the compression spring 9. At the same time, it provides displacement distance for the limiting cylinder 105 to slide down when locking the rotating shaft 102. A tapered guide is provided at the bottom of the limiting cylinder 105 to facilitate insertion into the limiting slot 202 of the second connecting part 2.

[0034] Reference Figure 4 and Figure 6 The second connecting part 2 includes a second fixing member 201 and a limiting slot 202. The second fixing member 201 is used to connect another wall panel.

[0035] The threaded rod 106 is rotatably mounted inside the large cavity of the connecting box 104, and a locking component 3 is connected to its outer side. The locking component 3 includes a threaded block 301, a sliding block 302, and a limiting groove 303. The threaded block 301 is fixedly mounted on the top of the limiting cylinder 105 for threaded engagement with the threaded rod 106. When the threaded rod 106 rotates, the threaded block 301 moves along the threaded rod 106, thereby causing the limiting cylinder 105 to slide. The sliding block 302 is fixedly mounted on the outer side of the threaded block 301. The limiting groove 303 is provided on the inner wall of the connecting box 104 for the sliding block 302 to slide, and the direction of the limiting groove 303 is parallel to the direction of the axis of the threaded rod 106, thereby allowing the limiting cylinder 105 to slide stably in a preset direction.

[0036] Reference Figure 7 The connecting box 104 is equipped with a drive assembly 4 for driving the threaded rod 106. The drive assembly 4 includes a drive worm gear 401, a drive worm 402, and a drive handle 403. The drive worm gear 401 is fixedly installed on the outside of the threaded rod 106. The drive worm 402 is used to cooperate with the worm gear to drive the threaded rod 106 to rotate. The drive handle 403 is installed at the end of the drive worm 402. By rotating the drive handle 403, the drive worm 402 can be driven to rotate. The self-locking property of the drive worm gear 401 and the drive worm 402 improves the stability of the device connection.

[0037] Reference Figure 7 and Figure 8A synchronization component 7 is provided between the extrusion block 6 and the threaded rod 106.

The positioning platform 701 is fixedly installed on the end face of the drive worm gear 401, and the positioning rod 702 is fixedly installed on the bottom end of the extrusion block 6. The positioning hole 703 is provided on the end face of the positioning platform 701 for the positioning rod 702 to be inserted. When the limiting cylinder 105 slides down to the set position, the positioning rod 702 is inserted into the positioning hole 703, so that the extrusion block 6 and the threaded rod 106 rotate synchronously, thereby extruding the transmission component 5 and driving the pin component 103 to achieve locking. The end of the positioning rod 702 is provided with a circular guide part to facilitate insertion into the positioning hole 703.

[0038] The connecting box 104 is equipped with a transmission assembly 5, which is used to drive the pin assembly 103 to move upward and lock the rotating shaft 102. The transmission assembly 5 includes a wedge block 501 and a pusher 502. The wedge block 501 is slidably installed in the small cavity of the connecting box 104 along the height direction of the wall panel. The pusher 502 abuts against the inclined surface of the wedge block 501 and is slidably installed on the inner wall of the connecting box 104 along the length direction of the wall panel. One end of the pin rod 1032 is fixedly installed on the top surface of the wedge block 501. When the pressing block 6 rotates, it presses the transmission assembly 5 to drive the pusher 502 to press and drive the wedge block 501 to move upward, thereby driving the pin rod 1032 to insert into the pin plate 1031 to achieve locking.

[0039] This application also includes a method for installing prefabricated wall panels, comprising the following steps: S1: The worker fixes the first connecting part 1 to the wall panel to be connected through the first fastener 101, fixes the second connecting part 2 to another wall panel through the second fastener 201, and adjusts the two wall panels to the position to be spliced. S2: The operator adjusts the orientation of the connecting box 104 by rotating the rotating shaft 102 so that the large chamber opening of the connecting box 104 is aligned with the limiting slot 202 of the second connecting part 2, and moves the second wall plate so that the end of the limiting cylinder 105 is opposite to the opening of the limiting slot 202. S3: The operator drives the threaded rod 106 to rotate through the drive assembly 4. The threaded rod 106 drives the limiting cylinder 105 to slide down from the large cavity of the connecting box 104 through the locking assembly 3 until the end of the limiting cylinder 105 is fully inserted into the limiting slot 202 of the second connecting part 2, thus completing the initial mechanical locking between the first connecting part 1 and the second connecting part 2. S4: When the limiting cylinder 105 slides down to the set position, the synchronization component 7 drives the extrusion block 6 to rotate synchronously with the threaded rod 106, and the extrusion block 6 extrudes the transmission component 5 during the rotation. S5: After the transmission component 5 is squeezed, the drive pin component 103 moves upward, so that the pin component 103 inserts into and locks the rotating shaft 102, thereby fixing the circumferential position of the connecting box 104 and the limiting cylinder 105, and completing the final connection between the first wall panel and the second wall panel.

[0040] The implementation principle of this application embodiment is as follows: When the worker uses this device to connect prefabricated wall panels, the first connecting part 1 and the second connecting part 2 are first connected to the wall panels to be connected by bolts. The angle of the rotating shaft 102 in the first connecting part 1 is adjusted according to the actual construction requirements, thereby adjusting the angle when connecting the wall panels. By inserting the second connecting part 2 into the first connecting part 1, the end of the limiting cylinder 105 corresponds to the opening of the limiting slot 202. The worker drives the driving worm 402 to rotate by driving the driving handle 403, thereby driving the threaded rod 106 to rotate synchronously by driving the worm wheel 401. Under the guidance of the sliding block 302 and the limiting groove 303, the limiting cylinder 105 moves along the thread. The axis of rod 106 slides downward and gradually inserts into the limiting slot 202 of the second connecting part 2 to achieve a fixed connection of the wall panel. When the limiting cylinder 105 slides down to the set position, the positioning rod 702 is inserted into the positioning hole 703, thereby driving the extrusion block 6 and the threaded rod 106 to rotate synchronously through the rotation of the positioning table 701. The extrusion block 6 extrudes the pusher 502, thereby pushing the inclined block 501 to slide up inside the small cavity of the connecting box 104, thereby driving the pin rod 1032 to move up and insert into the pin plate 1031 to lock the rotating shaft 102. When disassembling, it is only necessary to rotate the drive handle 403 in the opposite direction to drive the worm gear 402, so as to unlock the rotating shaft 102 first and then unlock the connection of the two sets of wall panels.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
