Step four, combining the heat-insulating layer with the steel bars: and binding and processing the reinforcement cage 41 required by the main structural layer, and connecting the second anchoring head 54 of the composite member after the heat-insulating layer is combined with the anchoring part with the reinforcement cage 41 through binding. And after the anchoring piece and the reinforcing steel bar are bound and fixed, the anchoring piece and the reinforcing steel bar are checked one by one, so that the length of the lower part of the anchoring piece is enough to extend into the middle of the decorative layer, and the end head of the upper part of the anchoring piece is enough to extend into the middle of the main structure layer.
Step five, forming the decorative layer cloth: and (3) distributing the stirred decorative layer material at the bottom of the die 1 by using a distributing machine, and vibrating to discharge air bubbles. Preferably, the vibration is carried out for 60s to remove air bubbles from the decorative layer material. When the cloth is distributed, the cloth heads are controlled to be distributed one by one according to areas or specific shapes, so that the purposes of enriching the decorative effect, not needing to be plastered and having thin and uniform layers are achieved.
Step six, laying an insulating layer and reinforcing steel bars: the anchoring piece, the heat insulation layer and the reinforcement cage are integrally placed above the decorative layer 2, wherein the heat insulation layer 3 is directly attached and laid on the decorative layer 2, namely the heat insulation layer 3 is arranged between the decorative material and the main structure material, so that the decorative layer material is not disturbed by the main structure material distribution and vibration; meanwhile, the middle heat-insulating layer can accommodate shrinkage deformation generated when different materials on two sides are molded and deformation generated by temperature difference between the inside and the outside of the building. While ensuring that the first anchoring head 53 of the anchor protrudes into the interior of the decorative layer 2.
Seventhly, forming main structure cloth: and (3) reserving and embedding according to needs, then distributing the stirred concrete on the heat insulation layer in the mould by using a distributing machine to form the main structure layer 4, vibrating the concrete to be compact, and finishing the forming of the wall PC member containing heat insulation decoration.

demolding and finishing: and demolding and turning the maintained PC component, performing decoration surface treatment on the outer vertical surface of the decoration layer 2 according to requirements, and continuously performing crystallization and processing of spraying a protective agent. Thereby obtaining better decorative effect of the outer vertical surface.
In the second step, the roughening treatment of the surface of the heat-insulating material is to roughen two surfaces of the heat-insulating material. And the heat-insulating material after roughening has enough bearing capacity, so that the main body structure layer mixture cannot be damaged after finishing cloth vibration on the upper surface.
And in the material distribution process in the fifth step and the seventh step, a numerical control material distribution head is adopted for material distribution. The numerical control material distribution head is adopted for distributing materials, so that a more stable and accurate material distribution effect can be obtained.
And in the seventh step, a material distributing machine is used for distributing on the heat insulation layer in the mould to form the main body structure layer, and the time for vibrating and compacting the concrete is less than or equal to the initial setting time of the decorative layer material. Firstly, the anchoring piece is ensured to be tightly combined with the mixture of the decorative layer; secondly, after the decoration layer is initially set, the vibration of the main structure cloth forming enables the decoration layer to generate stress cracks.
And (3) protecting components: when the components are stacked after being processed, the components are symmetrically placed, the outer vertical surface of the decorative layer 2 faces outwards, and the inclination angle between the components and the ground is not less than 80 degrees; the bottom of the component is provided with a through long batten, the four corners of the component are wrapped with rubber pads, and the decorative surface is wrapped with a thermoplastic film.
