[0023] By replacing the steel framework in PC with a light steel framework + steel mesh which is convenient for automatic processing and forming, and providing a hanging piece 8 on the light steel framework, the steel mesh is automatically connected, thereby eliminating the combination of the traditional steel framework + tie member, and manual binding is not required, which is convenient for realizing industrialized automatic mass production, saving labor, improving efficiency, and reducing cost. At the same time, the light steel framework is easy to automatically process and produce, and has large self-stiffness, and is suitable for vertical group pouring, thereby further improving production efficiency and reducing cost.

[0024] When as an outer wall structure, further comprising composite steel wire insulation board 6, the composite steel wire insulation board 6 comprises insulation board 6 and second steel mesh 5 arranged on at least one side of the insulation board 6 along the thickness direction, the insulation board 6 and the second steel mesh 5 are fixedly connected through a connecting structure such as a tie, the tie can adopt a short steel bar or an X-shaped steel bar, one end of which is tied or welded with the second steel mesh, and the other end is directly inserted into the insulation board 6, and the second steel mesh 5 can be hung on the hanging part 8, so that the composite steel wire insulation board 6 forms an integral whole with the concrete base body 1, the composite steel wire insulation board 6 is a product that is good in integrity, easy to install, and convenient for automatic assembly and production.

[0025] Further comprising inner and / or outer leaf board 7, the outer leaf board 7 is installed on the side of the composite steel wire insulation board 6 away from the concrete base body 1, and the inner leaf board is installed on the side of the concrete base body 1 away from the composite steel wire insulation board 6, which can adopt a demountable board structure, and acts as a formwork when pouring the concrete base body 1, further improving production efficiency. Specifically, the outer leaf board 7 and the inner leaf board can be connected with the light steel framework or the first and second steel meshes through connecting parts (such as nails or screws, etc.), or be adhesively connected with the concrete base body 1 or the insulation board 6 through cementing material, and the connecting mode can be selected according to actual requirements and strength requirements.

[0026] Specifically, in order to facilitate installation, a vertically arranged connecting square tube 11 is installed on at least one side of the light steel framework along the width direction of the concrete base body 1, and a plurality of connecting bolts 9 or connecting holes 12 are distributed on the connecting square tube 11 along the length direction thereof, the connecting bolts 9 can pass through the connecting holes 12 on the connecting square tube 11 of the adjacent concrete base body 1, and are used for connecting between the adjacent concrete base bodies 1, and an operation hand hole 10 corresponding to the connecting bolt 9 or the connecting hole 12 is formed on the connecting square tube 11. Specifically, the connecting square tube 11 is fixedly installed on the vertical framework 3 on one side of the light steel framework through self-tapping nails. The connecting hole 12 is a strip-shaped hole extending in the vertical direction, and correspondingly, the connecting bolt 9 is L-shaped, one end of which is fixed on the connecting square tube 11 through a nut, and the other end extends out of the connecting square tube 11 and extends downward after being bent. As shown in Figure 5 When two concrete base bodies 1 are connected, the connecting bolt 9 of one of the concrete base bodies 1 moves downward after passing through the connecting hole 12, so that the other end of the connecting bolt 9 abuts against the inner wall of the connecting square tube 11 of the adjacent concrete base body 1, realizing quick hanging connection, and then the operation hand hole 10 and the fastening nut are used for fastening, and finally the connection between the two concrete base bodies 1 is completed.

[0029] In summary, the present application replaces the steel reinforcement framework in the PC with a light steel framework that can be automatically processed and formed, and a steel mesh, and focuses on converting the sandwich core wallboard from the original scattered parts, such as steel bars, insulation boards, and tie members, which are manually combined, into the combination of industrial products, such as light steel frameworks, steel mesh sheets, and composite steel reinforced insulation boards, so as to realize industrialized automatic mass production, save labor, improve efficiency, and reduce costs. It is worth mentioning that the wallboard is similar to the light steel structure, but the structure stress is completely different. The light steel is mainly used for stress with steel keels, while the present structure is a steel reinforced concrete structure, which only replaces the original steel bars with light steel for automatic production. More importantly, the light steel structure separates the beams and the floor slabs, resulting in a decrease in net height and weak rigidity, and low market acceptance. The present structure is combined with the reinforced concrete floor slabs. In short, the present structure belongs to the reinforced concrete structure, while the light steel belongs to the steel structure, and is more suitable for the vertical production process of the wallboard. The light steel keel equipment produces the keels, the keels are assembled into a frame, the composite steel wire insulation board that is preformed is hung on the light steel keel, and the single-layer steel mesh is hung on the other side of the keel, forming a combined framework of the steel mesh + light steel framework + composite steel wire insulation board. The combined framework is placed in the vertical group mold, and the concrete is poured and vibrated to form the wall structure. In the present embodiment, the outer wall is divided into a structure layer 130 mm + an insulation layer 70-100 mm + an outer leaf layer 5 mm, and the inner wall only retains the structure layer, which is more suitable and flexible.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not to limit the technical solutions. Those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and should be covered in the scope of the claims of the present application.
