Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a prefabricated wall panel. Background Technology

[0002] Precast wall panels are building material panels that are prefabricated in a prefabrication yard for use in house construction. Precast wall panels are produced in factories, resulting in low cost, reliable quality, and easy installation, effectively increasing the speed of house construction.

[0003] Currently, when installing precast wall panels, they are usually first neatly arranged on the wall surface, and then pneumatic nails are driven into the four corners of the precast wall panels to fix them to the wall surface. However, since adjacent precast wall panels are not connected before fixing, relative displacement is likely to occur during the connection process, resulting in uneven wall panel arrangement, requiring frequent adjustments, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated wall panel to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a precast wall panel, comprising several panels, one side of which has a first groove and the other side has a second groove matching the first groove. Adjacent panels are detachably connected with caps for sealing the first and second grooves. A first pin is slidably connected inside the first groove. A sleeve for inserting the first pin is provided inside the second groove. The sleeve has a through groove. The first pin has a through slot for communicating with the through groove. A second pin is slidably connected inside the second groove. The second pin is used to pass through the through groove and insert into the through slot.

[0006] As a further feature of this utility model, a first connecting seat is provided inside the first groove, and the first pin is slidably connected inside the first connecting seat. A second connecting seat is provided inside the second groove, and the second pin is slidably connected inside the second connecting seat. Sliding grooves are provided on the top walls of both the first and second connecting seats, and push blocks are slidably connected inside the sliding grooves on both the first and second pins.

[0007] As a further feature of this utility model, the cover includes a locking frame, and when the locking frame is inserted into the first groove and the second groove, the locking frame and the first groove and the second groove are in an interference fit.

[0008] As a further feature of this invention, both the first and second grooves are provided with recessed slots, and the card frame is provided with a cover plate for embedding into the recessed slots.

[0009] As a further feature of this invention, force-applying grooves are provided on the side walls of the grooves.

[0010] As a further feature of this invention, all the panels are made of polyurethane material.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During installation, the panels can be assembled first. Specifically, adjacent panels can be aligned and fitted together, aligning and connecting the first and second grooves on the adjacent panels to form a complete groove. Then, the first pin is pushed from the first groove into the second groove until it is inserted into the sleeve. The second pin is then pushed down until it passes through the through groove and is inserted into the through groove, thereby locking the first pin in the slot and achieving a firm connection between the panels. This process is repeated until a complete wall panel is assembled. The wall panel is then fixed to the wall. Because the adjacent panels are pre-connected before fixing, their positions are locked, preventing relative displacement and ensuring a neat arrangement of the wall panels. This eliminates the tedious operation of frequent adjustments, making the operation more convenient, time-saving, and labor-saving. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-4 As shown, a precast wall panel includes several panels 1, all made of polyurethane material. Polyurethane material has good elasticity and corrosion resistance, thus improving the durability of the panels 1. A first groove 2 is formed on one side of each panel 1, and a second groove 3 matching the first groove 2 is formed on the other side. A cover for sealing the first groove 2 and the second groove 3 is detachably connected between adjacent panels 1. A first pin 4 is slidably connected inside the first groove 2, and a sleeve 5 for inserting the first pin 4 is provided inside the second groove 3. A through groove 6 is formed on the sleeve 5, and a through groove 7 for communicating with the through groove 6 is formed on the first pin 4. A second pin 8 is slidably connected inside the second groove 3, and the second pin 8 is used to pass through the through groove 6 and insert into the through groove 7. Therefore, in the precast wall panel... During installation, the panels 1 can be spliced ​​together first. Specifically, adjacent panels 1 can be aligned and fitted together, so that the first groove 2 and the second groove 3 on the adjacent panels 1 are aligned and connected to form a complete groove. Then, push the first pin 4 from the first groove 2 into the second groove 3 until it is inserted into the sleeve 5. Then push the second pin 8 down until it passes through the through groove 6 and is inserted into the through groove 7, thereby locking the first pin 4 in the slot and achieving a firm connection between the panels 1. Repeat the operation until a whole wall panel is formed, and then fix the wall panel to the wall. Since the adjacent panels 1 are pre-connected before fixing, their positions are locked, so there will be no relative displacement, ensuring the neat arrangement of the wall panels and eliminating the tedious operation of frequent adjustments, making the operation more convenient, time-saving and labor-saving.

[0020] Please see Figure 2-4 As shown, a first connecting seat 9 is provided inside the first groove 2, and a first pin 4 is slidably connected inside the first connecting seat 9. A second connecting seat 10 is provided inside the second groove 3, and a second pin 8 is slidably connected inside the second connecting seat 10. A sliding groove 11 is provided on the top wall of both the first connecting seat 9 and the second connecting seat 10. A push block 12 is provided on both the first pin 4 and the second pin 8, which is slidably connected inside the sliding groove 11. By pushing the push block 12 to slide in the sliding groove 11, the first pin 4 can be pushed out or retracted into the first connecting seat 9, and the second pin 8 can be pushed out or retracted into the second connecting seat 10, thereby realizing the connection or separation between adjacent plates. The operation is relatively convenient and simple.

[0021] Please see Figure 1-4As shown, the cap includes a retaining frame 13, which is made of PVC material, possessing good toughness and capable of elastic deformation. When the retaining frame 13 is inserted into the first groove 2 and the second groove 3, there is an interference fit between the retaining frame 13 and the first groove 2 and the second groove 3. Therefore, by inserting the retaining frame 13 into the first groove 2 and the second groove 3, the cap can be installed on the plate. By forcefully pulling the retaining frame 13 out of the first groove 2 and the second groove 3, the cap can be disassembled. The operation is convenient. Each groove 14 is provided, and a cover plate 15 is provided on the frame 13 for embedding into the groove 14. By embedding the cover plate 15 into the groove 14, the first groove 2 and the second groove 3 can be sealed, ensuring the flatness of the wall panel surface. Each groove 14 has a force-applying groove 16 on its side wall. When it is necessary to remove the cover, a tool can be inserted into the force-applying groove 16, and then the cover plate 15 can be pried off until the frame 13 is pulled out from the first groove 2 and the second groove 3. The force-applying groove 16 makes the operation of removing the cover easier and less strenuous.
