Description

Technical Field

[0001] This invention relates to the field of precast concrete wall panel technology, specifically to a connection structure for precast concrete wall panels that facilitates rapid assembly. Background Technology

[0002] Precast concrete wall panels are concrete wall panels that are first cast and cured in a factory before being transported to the construction site for installation. They typically consist of a concrete and steel reinforcement framework, or have circular or elliptical holes inside. They can also be constructed by combining outer leaf panels, insulation layers, and inner leaf panels. Precast concrete wall panels allow for control over dimensions and quality, significantly shortening the construction period. They are highly mechanized, resulting in less noise and dust pollution during on-site construction. They are widely used in construction and other fields. Precast concrete wall panels require assembly through connection structures, and there are various connection structures available on the market for precast concrete wall panels.

[0003] For example, Chinese patent CN218029137U discloses a connection structure for precast concrete wall panels, belonging to the field of concrete wall panel technology. This application includes a concrete wall panel body. A limiting groove is formed in the middle portion of one end of the concrete wall panel body. A limiting block is provided in the middle portion of the end of the concrete wall panel body away from the limiting groove. A fixing groove is formed inside the limiting block. A limiting rod is inserted through the fixing groove. A top plate is provided at the top of the limiting rod. Support mechanisms are provided on both sides of the concrete wall panel body. The support mechanisms include a support rod, a support plate, and an insertion rod. This application, by setting up a concrete wall panel body, limiting groove, limiting block, fixing groove, top plate, and limiting rod, allows for convenient connection of the concrete wall panel bodies when connecting them. The limiting block is inserted into the limiting groove, and then the limiting rod is inserted into the concrete wall panel body and the fixing groove, thus improving work efficiency.

[0004] Chinese Patent CN111101645A, for example, discloses a self-positioning reinforced precast concrete wall panel, its connection structure, and construction method, relating to the field of building wall panel construction. The concrete wall panel includes a precast reinforced wall body, vertical steel connectors embedded within the precast reinforced wall body, positioning keys embedded at intervals in one end face of the precast reinforced wall body, and self-positioning grooves at intervals on the other end face of the precast reinforced wall body. The positioning keys and self-positioning grooves are positioned vertically in a one-to-one correspondence. The positioning keys are metal protrusions with a smooth top surface. The precast reinforced wall body includes horizontal steel bars, vertical steel bars, and tie bars arranged at intervals, and is cast from concrete. At least one end of each vertical steel bar extends outside the precast reinforced wall body. The vertical steel connectors are vertically spaced or vertically continuous, encasing the horizontal and vertical steel bars. This invention solves the problem that existing concrete wall panels are heavy and difficult to position and install accurately, causing installation difficulties.

[0039] As attached Figure 9As shown, the assembly mechanism includes a mounting block 18, a second connecting block 19, and a magnetic block 20. The second connecting block 19 is connected to the interior of both the second connecting plate 4 and the third connecting plate 21 by slots.

[0040] Using the above technical solution, the assembly mechanism is formed by combining the mounting block 18 and the second connecting block 19, which facilitates the assembly of the second wall panel 2 and the third wall panel 24.

[0041] As attached Figure 1 Appendix Figure 2 and attached Figure 9 As shown, a first connecting plate 3 is installed on the right end of the first wall panel 1, and a second connecting plate 4 is installed on the left end of the second wall panel 2. The first wall panel 1 and the second wall panel 2 are installed together through the first connecting plate 3 and the second connecting plate 4. A fourth connecting plate 22 is installed below both the first wall panel 1 and the second wall panel 2. A fifth connecting plate 23 is installed above the third wall panel 24. The second wall panel 2 and the third wall panel 24 are assembled together through the fourth connecting plate 22 and the fifth connecting plate 23. Then, the fourth wall panel 25 is installed below the first wall panel 1 in the same way, and the second wall panel 2 and the third wall panel 24 are fixed by the assembly mechanism. The first wall panel 1 and the fourth wall panel 25 are also fixed by the assembly mechanism. As attached Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 8 As shown, the first connecting plate 3 is attached to the right end of the first wall panel 1, and then the mounting rod 5 is threaded to the first connecting plate 3, so that the left end of the mounting rod 5 is threaded to the first wall panel 1, and the first connecting plate 3 is fixed on the first wall panel 1. Then, the second connecting plate 4 is attached to the left end of the second wall panel 2, and the mounting rod 5 is threaded to the second wall panel 2 and the second connecting plate 4, so that the second connecting plate 4 is fixed on the second wall panel 2. Then, the first connecting plate 3 and the second connecting plate 4 are assembled together. As attached Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6As shown, the second connecting plate 4 is pushed backward, causing it to engage with the first connecting plate 3 in a slot. The first connecting plate 3 has an "L"-shaped cross-section, effectively limiting the second connecting plate 4. The limiting block 10 is slidably connected within the first connecting plate 3 via a support spring 11. Since the limiting block 10 has a triangular cross-section, when the second connecting plate 4 is connected to the first connecting plate 3, the second connecting plate 4 pushes the limiting block 10 to the left, causing it to retract into the first connecting plate 3 and compress the support spring 11. After the first connecting plate 3 and the second connecting plate 4 are fully engaged in the slot, the support spring 11 pushes the limiting block 10 back to its original position, causing it to engage with the rubber pad 15 within the second connecting plate 4 in a slot. The limiting blocks 10 are evenly distributed on the first connecting plate 3, effectively limiting the first connecting plate 3 and the second connecting plate 4 and preventing them from loosening. (See attached diagram) Figure 8 As shown, the cross-section of the first connecting plate 3 is an "L" shaped structure to ensure the stability of the second connecting plate 4. The first reinforcing rib 16 and the second reinforcing rib 17 are fixed inside the rear side of the first connecting plate 3. The first reinforcing rib 16 and the second reinforcing rib 17 are perpendicular to each other and are evenly distributed in the first connecting plate 3 to increase the strength of the rear end of the first connecting plate 3 and prevent the rear end of the first connecting plate 3 from breaking. As attached Figure 4 Appendix Figure 5 and attached Figure 7 As shown, when disassembly is required, the mounting handle 12 is connected to the disassembly plate 7. The front side of the disassembly plate 7 has a connecting groove 27, allowing the rear end of the mounting handle 12 to engage with the connecting groove 27. A sliding groove 14 is provided on the rear side of the connecting groove 27, symmetrically arranged about the center of the connecting groove 27. Rotating the mounting handle 12 by 90° allows the first connecting block 13, fixed to the rear end of the mounting handle 12, to engage with the sliding groove 14, effectively installing the mounting handle 12. Then, pulling the mounting handle 12 outwards causes it to move... The disassembly plate 7 moves, and a connecting rope 8 is fixed to the rear side of the disassembly plate 7. The connecting rope 8 pulls the limiting block 10 to move. When the connecting rope 8 moves, the connecting rope 8 slides on the outside of the auxiliary roller 9 connected to it in the slot. The longitudinal section of the auxiliary roller 9 is "H" shaped and is rotatably connected in the first connecting plate 3. The auxiliary roller 9 effectively supports and limits the connecting rope 8 and assists the movement of the connecting rope 8, so that the limiting block 10 moves stably. Adjust the position of the limiting block 10 so that the limiting block 10 is put into the first connecting plate 3, and the second wall panel 2 can be disassembled. As attached Figure 1 Appendix Figure 2 and attached Figure 9As shown, the fourth connecting plate 22 is fixed below the second wall panel 2 using the mounting rod 5, and the fifth connecting plate 23 is installed above the third wall panel 24 using the mounting rod 5. Then, the third wall panel 24 is installed below the second wall panel 2 using the fourth connecting plate 22 and the fifth connecting plate 23. Next, the second wall panel 2 and the third wall panel 24 are limited by the assembly mechanism. The third connecting plate 21 is installed on the left side of the third wall panel 24. The mounting block 18 is inserted between the second connecting plate 4 and the third connecting plate 21. The upper and lower ends of the mounting block 18 are... Each is fixed with a second connecting block 19, so that the two second connecting blocks 19 are respectively connected to the second connecting plate 4 and the third connecting plate 21 through the slot. The longitudinal section of the second connecting block 19 is a trapezoidal structure. The interior of the second connecting plate 4 and the third connecting plate 21 is fixed with a magnetic block 20, so that the second connecting block 19 is magnetically connected with the magnetic block 20 to ensure connection stability. The sixth connecting plate 26 is installed on the right end of the fourth wall panel 25. The fourth wall panel 25 is installed below the first wall panel 1 in the same way to facilitate flexible assembly of the first wall panel 1.
