Description

Technical Field

[0001] The utility model relates to the technical field of building decorative boards, and particularly relates to a fireproof and flame-retardant composite board. Background Art

[0002] Decorative boards and furniture materials are a kind of artificial boards. When used for decorating building walls, the building decorative boards are laid on the surface of indoor walls to provide a decorative effect for the indoor decorative boards, and at the same time, corresponding protection effects are provided through the decorative boards.

[0003] At present, when installing decorative boards, the decorative boards are usually adhered to the wall. Since most of the internal materials of the decorative boards are flammable, there are safety hazards when installed in an indoor environment. In case of a fire, it is easy to provide a fast transmission space for the fire source, and as the fire intensifies, the whole decorative board starts to burn. The multi-layer decoration increases the difficulty of extinguishing the fire, thereby causing more serious accidents and economic losses. Moreover, with the large-scale installation of building decorative boards, the existing assembly method is rather troublesome and not firm. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fireproof and flame-retardant composite board, which has the functions of fire prevention and heat insulation, and is convenient and firm to install.

[0005] Based on the above purpose, the utility model adopts the following technical solutions:

[0006] A fireproof and flame-retardant composite board includes a base plate. Above the base plate, a flame-retardant layer, a heat-insulating layer, a wear-resistant layer, and a waterproof layer are successively arranged. Below the base plate, a flame-retardant layer and a heat-insulating layer are successively arranged. Cover plates are arranged on the four side surfaces of the composite board. Connecting mechanisms are arranged on two corresponding cover plates. The connecting mechanism includes a card slot and a corresponding protruding part. The card slot is arranged on one of the cover plates, and the protruding part is arranged on the corresponding cover plate. The cover plate provided with the card slot is the first cover plate, and the cover plate provided with the protruding part opposite to the first cover plate is the second cover plate. A positioning mechanism is also arranged on the first cover plate and the second cover plate. The positioning mechanism includes a positioning hole arranged on the first cover plate and a positioning pin arranged on the second cover plate.

[0007] Preferably, the card slot is a strip-shaped recessed part penetrating through the first cover plate. At least two strip-shaped grooves are arranged on the inner wall of the strip-shaped recessed part. The protruding part is a strip-shaped protruding part penetrating through the second cover plate. At least two convex ribs matching the strip-shaped grooves are arranged on the outer wall of the strip-shaped protruding part.

[0008] Preferably, the card slot is arc-shaped or multi-prismatic, and the protruding part is arc-shaped or multi-prismatic corresponding to the card slot.

[0009] Preferably, there are four positioning holes, which are respectively arranged at the four corners of the first cover plate, and four matching positioning pins are arranged at the four corners of the corresponding second cover plate.

[0010] Preferably, there are 4 strip-shaped recessed parts and 4 strip-shaped convex parts that match them.

[0011] When the fireproof and flame-retardant composite board provided by the utility model is assembled, by sliding the convex part on the side cover plate of one fireproof and flame-retardant composite board into the card slot on the side cover plate of the adjacent composite board, the two composite boards are connected to each other. To prevent the convex part from sliding in the card slot, positioning pins and positioning holes are further provided, so that the two composite boards are more firmly and stably connected, and this connection method is also more convenient for disassembly and assembly.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The fireproof and flame-retardant composite board provided by the utility model has the functions of fireproofing and heat insulation, is safer for use as a building decorative board, and is convenient, firm, and stable to install, and is also convenient for disassembly and assembly.
