Description

Technical Field

[0001] This utility model belongs to the field of building exterior wall panel technology, specifically a leak-proof structure for prefabricated building exterior wall panels. Background Technology

[0002] Prefabricated building exterior wall panels refer to building exterior wall materials that are prefabricated in a factory and assembled on site. These exterior wall panels have characteristics such as lightweight, high strength, thermal insulation, waterproofing, and moisture resistance, and are gradually becoming the preferred choice for modern building exterior wall materials.

[0003] Based on the above, it was found that during construction, traditional prefabricated building exterior wall panels are usually connected to the building wall by bonding or bolting. However, there are often gaps between the panels, resulting in relatively poor sealing. After long-term use, leakage may occur, causing the internal wall surface and exterior wall panel structure to be eroded by rain, snow, and other environmental factors. This leads to severe dampness, reduced insulation, and a significantly shortened lifespan of the building. Therefore, in view of this, research and improvement are needed for the existing structure.

[0004] Therefore, a leak-proof structure for prefabricated building exterior wall panels is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a leak-proof structure for prefabricated building exterior wall panels. This structure prevents gaps from forming during the splicing of exterior wall panels, thus ensuring their airtightness and avoiding problems such as leakage and erosion at the joints, thereby greatly improving the service life of the building.

The decorative panel 7 is fixedly connected to wall panel 1 and wall panel 2 respectively by multiple screws.

[0025] The seepage-proof component 5 includes a water-blocking strip 501 installed in the sealing groove 4. Both ends of the water-blocking strip 501 are fixedly connected to a locking block 502, and the locking block 502 is engaged with the side wall of the sealing groove 4. A panel 503 is fixedly connected to the middle of the back of the water-blocking strip 501. One end of the panel 503 is engaged at the joint between wall panel 1 and wall panel 2. The water-blocking strip 501 is a hollow structure and is filled with activated carbon 504 to block the gap at the joint between wall panel 1 and wall panel 2. At the same time, activated carbon 10 is filled inside the water-blocking strip 501. Utilizing the water absorption and moisture-proof effect of activated carbon 10, the sealing performance at the joint between wall panel 1 and wall panel 2 can be greatly improved, resulting in a significant improvement in the overall seepage-proof effect.

[0026] Specifically, a positioning plate 8 is fixedly connected to the side of the trim panel 7 near the water-blocking strip 501. The positioning plate 8 is snapped into the front of the water-blocking strip 501, thereby positioning the trim panel 7 and preventing it from coming off during use.

[0027] like Figures 1 to 5 As shown, the inner walls at both ends of the sealing groove 4 are provided with slots, and corresponding locking blocks 502 are engaged in the slots, so that the water-blocking strip 501 can be installed inside the sealing groove 4.

[0028] Furthermore, sealing grooves 9 are provided at both ends of the front of wall panel 1 and wall panel 2, and the sealing grooves 9 are located between the corresponding opening grooves 3 and positioning grooves 6. A water-blocking block 10 is fixedly connected to the side of the decorative panel 7 near the water-blocking strip 501, and the water-blocking block 10 is engaged with the corresponding sealing groove 9, thereby further improving the seepage prevention effect.

[0029] It is worth noting that two mounting slots 11 and two mounting blocks 12 are respectively provided at both ends of wall panel 1 and wall panel 2. The mounting blocks 12 on wall panel 1 are snapped into the corresponding mounting slots 11 on wall panel 2 and fixed by bolts, so that wall panel 1 and wall panel 2 can be stably connected.

[0032] Among them, the structures such as wall panel 1 and wall panel 2 are existing technologies and will not be described in detail; at the same time, they are not the main technical points of this patent, and their working principle is a well-known technology. The appropriate model is selected according to actual use, so they will not be explained in detail.

[0033] Working principle and process: Wall panel 1 is fixed to the building wall using mounting base 13 and bolts. Then, wall panel 2 is connected to wall panel 1 using mounting block 12 and mounting groove 11. Finally, wall panel 2 is fixed to the building wall using mounting base 13 and bolts. At this time, a waterproof component 5 is installed in the sealing groove 4 at the connection between wall panel 1 and wall panel 2. The water-blocking strip 501 is installed into the sealing groove 4 through the clip 502 and the insert 503, thereby realizing the splicing of wall panel 1 and wall panel 2. The gaps are blocked, and activated carbon 504 is filled inside the water-blocking strip 501. Utilizing the water absorption and moisture-proof effect of activated carbon 504, the sealing performance at the connection between wall panel 1 and wall panel 2 can be greatly improved, resulting in a significant improvement in the overall seepage prevention effect. Finally, the decorative panel 7 is fixed to the connection between wall panel 1 and wall panel 2. With the cooperation of the sealing wedge, not only can the seepage prevention component 5 be limited to prevent loosening and falling off, which would affect the seepage prevention effect, but it can also beautify the connection between wall panel 1 and wall panel 2.
