At the same time, low-cost phosphogypsum can be used to make the wall panel with lower cost and lighter weight per unit volume. Specifically, since the inner cavity of the wall panel is filled with expanded slurry, the solute is low. For example, the weight of a wall with a thickness of 120 mm is only 60 kg per square meter.

[0085] Example 5

[0086] like Figure 2-12 As shown, based on Example 4, this embodiment provides a preferred structure that can make the wall panel more solid: a plurality of reinforcing partitions 4 are installed in sequence along the length direction of the frame 2, and the top surface of the reinforcing partition 4 contacts the bottom surface of the top plate 3, and the bottom surface contacts the top surface of the bottom plate 1.

[0087] In this embodiment: after pouring the expanded slurry into the frame 2, the expanded slurry can firmly connect the top plate 3 and the bottom plate 1 through the reinforcing partition 4, so that the entire wall panel can be more solid.

[0088] Preferably, the top surface of the bottom plate 1 is installed with a plurality of lower connecting strips 5 along its length direction, the bottom surface of the top plate 3 is installed with a plurality of upper connecting strips 8 along its length direction, the bottom surface of the reinforcing partition 4 is provided with a lower groove 42, and the top surface is provided with an upper groove 41, the upper connecting strip 8 is located in the upper groove 41, and the lower connecting strip 5 is located in the lower groove 42, the top plate 3 is connected to the reinforcing partition 4 through the upper connecting strips, and the bottom plate 1 is connected to the reinforcing partition 4 through the lower connecting strips, so that the connection strength between the bottom plate 1, the frame 2 and the top plate 3 can be further increased, thereby further increasing the strength of the wall panel.

[0089] Preferably, both sides of the upper clamping groove 41 are provided with upper clamping inclined surfaces 411, and both sides of the lower clamping groove 42 are provided with lower clamping inclined surfaces 421. The two side surfaces of the upper connecting bar 8 are mutually fitted with the upper clamping inclined surfaces 411, and the two side surfaces of the lower connecting bar 5 are mutually fitted with the lower clamping inclined surfaces 421. The two side surfaces of the upper connecting bar 8 are mutually fitted with the upper clamping inclined surfaces 411, and the two side surfaces of the lower connecting bar 5 are mutually fitted with the lower clamping inclined surfaces 421. After the puffed slurry is puffed, the upper connecting bar 8 and the top plate 3 can be more tightly connected together, and similarly, the lower connecting bar 5 and the bottom plate 1 can be more tightly connected together, so that the top plate 3, the frame 2 and the bottom plate 1 can be further connected more firmly, and the strength of the wallboard can be further increased.

[0090] Preferably, the outer surface of the frame 2 is provided with a card slot and a card edge 9, and multiple frames 2 are connected by the card slot and the card edge 9, so that the thermal insulation and sound insulation wall panels after manufacturing can be connected to each other by the card slot and the card edge 9, and then the thermal insulation and sound insulation wall panels can be installed by filling the connecting mortar between the thermal insulation and sound insulation wall panels, and other connecting parts are no longer needed. In this way, multiple thermal insulation and sound insulation wall panels can be installed more quickly and efficiently.
