Description

Technical Field

[0001] The utility model relates to the technical field of precast wall panels, and particularly relates to a precast wall panel. Background Art

[0002] Precast wall panels generally refer to precast concrete wall panels, which are processed in precast factories or construction sites into reinforced concrete slab-type components for building assembly, simply referred to as wall panels or wall boards. Using precast concrete wall panels to build precast large-panel buildings can improve the degree of factory and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the building construction period.

[0003] The assembly of existing precast wall panels is too simple, and they are all assembled by relying on screws and adhesives. The assembly of the wall panels is not stable enough, and most precast wall panels only pursue high strength and do not pay much attention to other aspects, resulting in not being able to meet the market demand.

[0004] Therefore, it is very necessary to invent a precast wall panel to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a precast wall panel to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A precast wall panel, including a back panel and a wall panel body. A plurality of first notches are opened on the back panel. One side of the wall panel body is connected with a plurality of first clamping blocks corresponding to the first notches. One side of the wall panel body is connected with a second clamping block. The other side of the wall panel body is opened with a second notch corresponding to the second clamping block. The wall panel body includes a protective layer, a waterproof layer, a flame-retardant layer, and a heat-insulating layer.

[0007] Preferably, a first strip-shaped opening is opened at the top of the wall panel body. A first protective plate is connected at the first strip-shaped opening. The top of the first protective plate is connected with a plurality of first strip-shaped blocks corresponding to the first strip-shaped opening. The bottom of the first protective plate is connected with a plurality of wedge-shaped blocks. A second strip-shaped opening is opened on one side of the back panel. A second protective plate is connected at the second strip-shaped opening. One side of the second strip-shaped block is connected with a second strip-shaped block. The second protective plate is closely attached to the wall panel body.

[0008] Preferably, the specific material of the waterproof layer is cement fiber board.

[0009] Preferably, the specific material of the flame-retardant layer is gypsum board.

[0010] Preferably, the specific material of the heat-insulating layer is polystyrene board.

[0011] Technical effects and advantages of the present utility model: By using a flame retardant layer, a waterproof layer, a thermal insulation layer, a first clamping block, and a second clamping block in combination, the backboard and the wallboard body can be connected together through the first clamping block and the first notch, and the second clamping block and the second notch can connect multiple wallboard bodies together. The cement fiber board used as the waterproof layer can ensure stable performance and is not easily deformed in a humid environment. The gypsum board used as the flame retardant layer has excellent fire prevention and heat insulation capabilities. The polystyrene board used as the thermal insulation layer has good heat insulation capabilities, effectively reducing heat dissipation. It can make the assembly and combination of the wallboard more stable, the wallboard has more functions, and meets the broad needs of the market. Description of the Drawings
