[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a prefabricated exterior wall panel structure composed of a steel frame, a steel mesh, a filling core material, a glass fiber mesh cloth and a mortar surface layer, thereby reducing the demand for molds and achieving the purpose of reducing processing difficulty, shortening the construction period and reducing construction difficulty.

[0021] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0022] like Figure 1 As shown, a prefabricated assembled composite exterior wall panel structure includes a rectangular steel frame 1, a steel wire mesh 2 arranged in the steel frame, five square steel reinforcing ribs 3 arranged in the steel frame, a filling core material 4 arranged on the steel frame, a glass fiber mesh cloth 5 arranged on the surface of the filling core material, and a mortar surface layer 6 filled on the glass fiber mesh cloth.

[0023] Wherein: both ends of the square steel reinforcing ribs are welded to the steel frame, five reinforcing ribs are evenly distributed in a square shape along the length of the steel frame, and the square steel reinforcing ribs are mounted on the steel wire mesh.

[0024] The four corners of the steel frame are provided with oblong holes for installation, and the side walls of the steel frame are provided with hoisting holes for hoisting.

[0025] The specific use steps of the utility model are as follows: Figure 1 As shown, the filling core material is a lightweight concrete filling core material; the steel frame material is a light steel galvanized C type; the mortar surface layer is a polymer anti-cracking mortar surface layer [the composition of the polymer anti-cracking mortar in this embodiment mainly includes cement, sand, polymer emulsion, admixtures, etc.; cement is the most basic component of the polymer anti-cracking mortar, which is used to provide the adhesion of the mortar, and provide the strength and stability of the mortar; sand is the main filler, which can increase the strength of the mortar; polymer emulsion is used as a reinforcing agent to provide the mortar with anti-cracking performance and reduce shrinkage; admixtures are used to improve the performance of the mortar, including waterproofing agents, water reducing agents, etc., which are combined to achieve excellent anti-cracking performance and durability. Technicians in this technical field can add other auxiliary materials according to actual needs].

[0026] In actual operation, the production process of the exterior wall panel is as follows:

[0027] 1. Welding and production of steel frame:

[0028] The steel frame, steel wire mesh and square steel reinforcement ribs are made to size according to the component detailed drawings. All joints are fully welded, the welds are even, smooth, firm and the welding dimensions are accurate.

[0029] 2. Cleaning the mold and positioning the steel frame:

[0030] Clean the surface of the fixed mold base and evenly apply the release agent (or lay plastic film), lay and fix the steel frame, keep the ground clean, dry, free of particles, and lay the frame straight without overhanging.

[0031] 3. Slurry mixing and conveying

[0032] Measure and mix according to the production ratio, and use material transport vehicles to transport the slurry. During the process, strictly implement the material ratio and mix evenly, and avoid spillage during material transportation and unloading.

[0033] 4. Pouring and paving the surface layer

[0034] Pour the slurry evenly and spread it flat. After the slurry is initially hardened, it forms a filling core material. Then, lay the fiberglass mesh cloth on the filling core material. After the laying is completed, fill the mortar again to form a mortar surface layer. The mortar should be filled evenly, densely, spread flatly, with clean borders and no leakage.

[0035] 5. Lifting, stacking and maintenance

[0036] After hardening to strength, use vehicles to lift and operate, and centrally stack for maintenance. During this process, evenly arrange the lifting points, slowly lift and lower, stack and align the upper and lower parallels (should not exceed 10 layers and must not exceed 13 layers), and place the pads evenly at both ends and the middle (no less than 3 on each side).

[0037] No specific molds are required during the entire process, and the exterior wall panels produced are green and environmentally friendly, high-strength and fire-resistant, with improved performance.

[0038] Through the above methods, the prefabricated assembled composite exterior wall panel structure provided by the utility model reduces the demand for molds by providing a prefabricated exterior wall panel structure composed of a steel frame, a steel mesh, a filling core material, a glass fiber mesh cloth and a mortar surface layer, thereby achieving the purpose of reducing processing difficulty, shortening construction period and reducing construction difficulty.

[0039] The above is only a preferred implementation of a prefabricated assembled composite exterior wall panel structure disclosed by the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all belong to the protection scope of the utility model.
