Description

Technical Field

[0001] This utility model relates to the field of construction, specifically to a modular prefabricated building wall panel quick connection structure. Background Technology

[0002] In the process of modern building industrialization, modular prefabricated buildings have become an important direction for the development of the construction industry due to their advantages such as high efficiency, environmental protection, and controllable quality. Among them, building wall panels, as a core component of modular prefabricated buildings, directly affect the overall stability, construction efficiency, and ease of maintenance of the building through the performance of their connection structure. Therefore, developing safe, reliable, and easy-to-operate rapid connection structures for wall panels is a key step in promoting the widespread application of modular prefabricated buildings.

[0003] Traditional wall panel connection structures have obvious drawbacks: reliance on on-site welding or complex bolt assembly leads to low efficiency, and the operation by professional personnel and repeated alignment severely slows down the construction progress; poor component compatibility results in insufficient connection stability, making them susceptible to loosening and displacement due to temperature changes and vibrations; strict requirements for installation accuracy and difficulties in subsequent disassembly and assembly make it difficult to adapt to deviation adjustments and maintenance needs. These problems stand in stark contrast to the high efficiency, stability, and flexibility of the above-mentioned solutions. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a modular prefabricated building wall panel quick connection structure. The design is as follows: during splicing, the wall panel approaches and drives the dovetail structure's sliding rod to slide along the sliding groove seat. The sliding rod pushes the three-pronged transmission component downward through the swing arm, causing the wedge block to enter between the two clamping seats. After the clamping seats assemble and wrap around the wedge block, the coaxial bolt holes are used to insert bolts for fixation. During unlocking, the bolts are removed, the wall panel separates and drives the sliding rod to slide in the opposite direction. The swing arm pulls the three-pronged transmission component upward, causing the wedge block to detach from the clamping seat.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular prefabricated building wall panel quick-connect structure, including a wall panel, wherein the wall panel is provided with a sliding groove seat, the sliding groove seats are symmetrically arranged on the inner wall surface of the wall panel splicing end, and a sliding rod is slidably connected inside the sliding groove of each of the two sliding groove seats. A swing arm is hinged to the top right side of each sliding rod, and the other end of each pair of swing arms is hinged to the top of a three-pronged transmission component. The three-pronged transmission component is vertically arranged between the opposing inner walls of the two wall panels to be spliced, and a locking device is provided at its bottom end extending downwards.

[0006] The locking device includes a wedge block, which is located at the bottom of the three-pronged transmission component. A retaining seat is fixedly installed on the left and right sides of the inner wall of the wall panel splicing end below the wedge block. The retaining seat has a groove that fits the wedge block on its inner side. The meshing part of the retaining seat and the wedge block has a bolt hole through it, and they are coaxially arranged when the retaining seat is spliced ​​and wraps around the wedge block.

[0007] Furthermore, the sliding seat and the clamping seat are fixed to the inner wall surface of the wall panel splicing end by bolts.

[0008] Furthermore, the slide seat adopts a dovetail groove structure and the slide rod is a dovetail structure adapted to the dovetail groove structure.

[0009] Furthermore, the three-pronged transmission component and the wedge block are integrally formed.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] 1. Significant efficiency advantages: First, installation is convenient and efficient. All components are prefabricated in the factory, eliminating the need for complex welding or multiple bolt operations on site. The components are initially fitted by the wall panel moving closer together, and then fixed with coaxial bolts, which greatly shortens the installation time. Second, maintenance and replacement are convenient. Unlocking only requires removing the bolts, and the components are reset and separated by the reverse force of the wall panel separation, which facilitates later maintenance or replacement.

[0012] 2. Outstanding connection performance: On the one hand, the connection is stable and reliable. The dovetail structure slide rod and slide groove seat fit tightly together, and the wedge block and the clamping seat are precisely engaged and fixed with coaxial bolts to form multiple locking, which enhances the shear and tensile resistance and can cope with external influences. On the other hand, it has strong adaptability. The structural design can adapt to certain installation deviations, reduce splicing difficulties caused by precision issues, and improve connection reliability. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figs. 1-3 The modular prefabricated building wall panel quick connection structure in this embodiment includes a sliding groove seat 1, which is symmetrically arranged on the inner wall surface of the wall panel splicing end. Sliding rods 2 are slidably connected inside the sliding grooves of both ends of the sliding groove seat 1. A swing arm 3 is hinged to the top right side of each sliding rod 2. The other ends of both pairs of swing arms 3 are hinged to the top of a three-pronged transmission component 4. The three-pronged transmission component 4 is vertically arranged between the opposing inner walls of the two wall panels to be spliced, and a locking device 5 is provided at its bottom end extending downwards.

[0019] The locking device 5 includes a wedge block 501, which is located at the bottom of the three-pronged transmission component 4. A retaining seat 502 is fixedly installed on the left and right sides of the inner wall of the wall panel splicing end below the wedge block 501. The retaining seat 502 has a groove that matches the wedge block 601 on its inner side. The meshing part of the retaining seat 502 and the wedge block 501 is provided with a bolt hole 503, and they are coaxially arranged when the retaining seat 502 splices and wraps around the wedge block 501.

[0020] The sliding seat 1 and the clamping seat 502 are fixed to the inner wall surface of the wall panel splicing end by bolts. The bolt fixing method not only makes the connection firm, but also facilitates disassembly and adjustment as needed in the later stage, which enhances the flexibility of structural installation.

[0021] The slide seat 1 adopts a dovetail groove structure and the slide rod 2 is a dovetail structure that is compatible with the dovetail groove structure. This structural fit can effectively prevent the slide rod 2 from detaching from the slide seat 1, while ensuring the precise guidance of the slide rod 2 during the sliding process, thus improving the stability and reliability of the sliding.

[0022] The three-way drive component 4 and the wedge block 501 are integrally molded structures. The integral molding design avoids the connection gap that may occur when the two are assembled, enhances the strength and rigidity of the overall structure, and can transmit power more stably.

[0023] The groove on the inner side of the clamping seat 502 is an inclined groove that matches the inclination angle of the wedge block 501. The matching inclination angle allows the clamping seat 502 and the wedge block 501 to fit tightly together, increasing the contact area, improving the biting force during locking, and enhancing the stability of the connection.

[0024] Bolt hole 503 is provided with internal thread and is compatible with external hex bolts. The internal thread design can form a reliable threaded connection with the bolt to prevent loosening, while the external hex bolt is easy to operate with a wrench, improving the convenience of installation and disassembly.

[0025] In summary, the operating principle of this modular prefabricated building wall panel quick connection structure is as follows: When splicing wall panels, as two wall panels to be spliced ​​approach each other, the sliding rod will naturally slide along the track of the sliding seat. The movement of the sliding rod will simultaneously drive the swing arm that is hinged to it to generate linkage. The swing arm will then push the three-pronged transmission component downward, so that the wedge-shaped block at the bottom of the three-pronged transmission component gradually enters the space between the two clamping seats. As the wall panels continue to approach, the wedge-shaped block will precisely fit with the groove on the inner side of the clamping seat. Finally, by passing the bolt through the bolt hole that is now in a coaxial state, the two wall panels can be stably connected. When disassembly is required, simply remove the fixing bolts first, and then separate the two wall panels in opposite directions. The separation of the wall panels will cause the sliding rod to slide in the opposite direction, and then the swing arm will pull the three-pronged transmission component upward, so that the wedge-shaped block will disengage from the clamping seat, realizing the smooth disassembly of the wall panel.

[0026] The design of this structure offers significant advantages. The bolted fixing of the slide rail seat and the retaining seat ensures a stable connection between these components and the wall panel, preventing loosening during long-term use. It also allows for easy disassembly and reinstallation when maintenance, component replacement, or wall panel repositioning is required, greatly enhancing operational flexibility. The dovetail-shaped slide rail seat and slide rod work together; the special shape of the slide rail seat effectively constrains the slide rod, preventing it from falling off during sliding. It also guides the slide rod to slide smoothly along the preset trajectory, avoiding deviation or jamming and ensuring stable and reliable sliding. The three-pronged transmission component and wedge block are integrally molded, making them an inseparable whole, eliminating the limitations of traditional assembly methods. The existing connection gap enhances the overall strength and rigidity of the structure, allowing for a more direct and stable transmission of force from the three-way drive to the wedge block during power transmission, reducing power loss. The angle matching design of the engagement seat and the wedge block ensures a tight fit when they are engaged, increasing the contact area and resulting in a stronger locking force, thus effectively improving the stability of the connection. Even under the influence of external forces, the connection remains in good condition. The combination of the internal threaded bolt hole and the external hexagonal bolt allows the internal thread to form a tight threaded connection with the bolt, enhancing the reliability of the connection and effectively preventing loosening during use. The design of the external hexagonal bolt facilitates operation with common wrench tools, making both tightening during installation and loosening during disassembly more convenient and labor-saving.
