Description

Technical Field

[0001] This utility model relates to the field of composite board technology, specifically a moisture-proof and flame-retardant composite board. Background Technology

[0002] Moisture-proof and flame-retardant composite boards generally consist of an outer layer, a middle layer, and an inner layer. The outer layer is usually made of coated board, with the outer surface coated with flame retardants such as insoluble ammonium polyphosphate flame retardant that do not absorb moisture, which plays a role in flame retardancy and preventing moisture intrusion. The middle layer is a soaked board, which is soaked in water-soluble ammonium polyphosphate solution, which reduces costs and further improves flame retardant performance. The inner layer can also use a similar soaked board or other materials with certain strength and flame retardant properties.

[0003] The joints of existing moisture-proof and flame-retardant composite panels are generally connected by adhesive, which results in poor moisture resistance and strength compared to the panels themselves. Therefore, a moisture-proof and flame-retardant composite panel is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a moisture-proof and flame-retardant composite board to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A moisture-proof and flame-retardant composite board includes a support layer, a moisture-proof layer, and a flame-retardant layer. Moisture-proof layers are fixedly connected to both sides of the support layer, and a flame-retardant layer is fixedly connected to the side of the moisture-proof layer away from the support layer. First connecting grooves are formed on both sides of the support layer, moisture-proof layer, and flame-retardant layer. A sealing layer is provided inside the first connecting grooves. A connecting block is fixedly connected inside the sealing layer. A second connecting groove is formed on the inner side of the connecting block and the sealing layer. Limiting plates located inside the second connecting grooves are fixedly connected to both ends of the support layer. A sealing sleeve located inside the second connecting groove is fixedly connected to the outer side of the limiting plates. A first fixing hole is formed on the surface of the support layer. A second fixing hole penetrating the sealing layer and the connecting block is formed on the outer side of the sealing layer and the connecting block. Fixing pins are provided inside the first and second fixing holes.

[0006] Preferably, the inner shape of the first fixing hole and the second fixing hole matches the shape of the fixing pin, both being cylindrical, and the inner dimensions of the first fixing hole and the second fixing hole match the dimensions of the fixing pin.

[0007] Preferably, the inner shape of the second connecting groove matches the shape of the combined support layer, limiting plate and sealing sleeve, all being T-shaped, and the inner dimensions of the second connecting groove match the dimensions of the combined support layer, limiting plate and sealing sleeve.

[0008] Preferably, the two moisture-proof layers and the flame-retardant layer are grouped together with one support layer, and there are two groups in total. The two moisture-proof layers and the flame-retardant layer are symmetrically arranged on both sides of the sealing layer and the connecting block with one support layer.

[0009] Preferably, the shape of the two first connecting grooves combined together matches the shape of the sealing layer, both being H-shaped, and the size of the two first connecting grooves combined together matches the size of the sealing layer.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the first connecting groove, connecting block, second connecting groove, limiting plate, first fixing hole, second fixing hole and fixing pin are provided. The double-layer connection structure formed by the first connecting groove and connecting block and the second connecting groove and limiting plate effectively strengthens the connection strength. The connecting block and limiting plate support the connection, and the fixing pin, first connecting hole and second connecting hole further strengthen the connection strength and prevent the glued connection structure from falling off. This solves the problem that the splicing of existing moisture-proof and flame-retardant composite boards, which are generally glued, has poor moisture-proof effect and strength at the connection compared to the board body. 2. In this utility model, the sealing sleeve and sealing layer can form a double sealing structure at the connection, which enhances the moisture-proof effect at the connection and prevents moisture from seeping in from the connection.

[0016] Please see Figure 1-3 This utility model provides a technical solution: A moisture-proof and flame-retardant composite board includes a support layer 1, a moisture-proof layer 2, and a flame-retardant layer 3. The moisture-proof layer 2 is fixedly connected to both sides of the support layer 1, and the flame-retardant layer 3 is fixedly connected to the side of the moisture-proof layer 2 away from the support layer 1. A first connecting groove 4 is formed on both sides of the support layer 1, the moisture-proof layer 2, and the flame-retardant layer 3. A sealing layer 5 is provided inside the first connecting groove 4. A connecting block 6 is fixedly connected inside the sealing layer 5. A second connecting groove 7 is formed on the inner side of the connecting block 6 and the sealing layer 5. A limiting plate 8 located inside the second connecting groove 7 is fixedly connected to both ends of the support layer 1. A sealing sleeve 9 located inside the second connecting groove 7 is fixedly connected to the outer side of the limiting plate 8. A first fixing hole 10 is formed on the surface of the support layer 1. A second fixing hole 11 penetrating the sealing layer 5 and the connecting block 6 is formed on the outer side of the sealing layer 5 and the connecting block 6. A fixing pin 12 is provided inside the first fixing hole 10 and the second fixing hole 11.

[0017] The inner shapes of the first fixing hole 10 and the second fixing hole 11 match the shape of the fixing pin 12, both being cylindrical. The inner dimensions of the first fixing hole 10 and the second fixing hole 11 match the dimensions of the fixing pin 12, which can increase the stability of the fixing pin 12 and prevent the fixing pin 12 from shaking. The inner shape of the second connecting groove 7 matches the shape of the support layer 1, the limiting plate 8 and the sealing sleeve 9 combined, both being T-shaped. The inner dimensions of the second connecting groove 7 match the dimensions of the support layer 1, the limiting plate 8 and the sealing sleeve 9 combined, which can effectively strengthen the sealing effect at the connection. The two moisture-proof layers 2 and the flame-retardant layer 3 are grouped with one support layer 1, and there are two groups in total. The two moisture-proof layers 2 and the flame-retardant layer 3 are symmetrically arranged on both sides of the sealing layer 5 and the connecting block 6, which can strengthen the support strength at the connection. The shape of the two first connecting grooves 4 combined matches the shape of the sealing layer 5, both being H-shaped. The dimensions of the two first connecting grooves 4 combined match the dimensions of the sealing layer 5, which further strengthens the sealing effect and forms a double sealing structure.

[0018] Workflow: When a moisture-proof and flame-retardant composite board is required, firstly, the two sets of support layers 1, moisture-proof layer 2, and flame-retardant layer 3 are joined together. Then, the connecting block 6 and sealing layer 5, which are coated with glue, are aligned with the first connecting groove 4 and snapped in. While the connecting block 6 is snapping in, the limiting plate 8 and sealing sleeve 9 will also enter the second connecting groove 7 simultaneously, forming a double connection structure. Then, glue is injected into the first fixing hole 10 and the second fixing hole 11. After that, the fixing pin 12 is inserted into the first fixing hole 10 and the second fixing hole 11 to complete the splicing of the two sets of composite boards.
