Description

Technical Field

[0001] The invention relates to a composite wall panel and a production method thereof, in particular to a composite wall panel of a novel socket steel plate and a production method thereof, belonging to the technical field of industrial building design and construction. Background Art

[0002] Commonly used flat steel plate walls in steel structure workshops include single-layer pure flat steel plate walls and double-layer rock wool sandwich panel walls. Single-layer pure flat steel plate walls are easy to construct and beautiful in appearance, but their fire prevention, thermal insulation and sound insulation performance are poor. In addition, since the surface of the single-layer steel plate is easily deformed, uneven bulges are prone to appear on the building surface during use, reducing the appearance of the building. Double-layer rock wool sandwich panel walls paste rock wool core materials between two layers of flat steel plates, thereby improving the problems of poor thermal insulation and uneven surface of single panels. However, the preparation of double-layer composite flat steel plate walls requires a series of automated processes such as steel plate profiling, rock wool cutting, spraying composite, thermal curing and foaming sealing. The composite process is complex, the overall cost is high, the economy is poor, and it is difficult to promote.

[0003] In summary, the development of a high-cost-effective composite wall panel that is lightweight, earthquake-resistant, heat-insulating, sound-insulating, and easy to construct and can be produced in a standardized and automated manner is an urgent need in the field of industrial building design and construction technology. Therefore, the present invention is proposed. Summary of the invention

[0006] The male edge includes an upper edge and a lower edge, and an inner recess is formed between the upper edge and the lower edge through an oblique edge and a vertical edge; the female edge includes a first step, a second step, a middle edge and a lower bottom from top to bottom, and the middle edge is a raised portion. When connected, the middle edge enters the inner recess, and the lower edge abuts against the lower bottom, the second step enters the inner recess, and the upper edge abuts against the first step.

[0007] The exterior wall colored steel plate is a pure flat colored steel plate or a small corrugated colored steel plate.

[0008] The sandwich layer is a rock wool sandwich layer or a foamed polystyrene sandwich layer, the veneer layer is a kraft paper veneer layer, and the adhesive is a polyurethane adhesive.

[0009] A method for producing a novel composite wall panel of a socket steel plate comprises the following steps: (1) According to the project structural design and architectural design requirements, select the appropriate type and thickness of the exterior wall color steel plate, and determine the bending height H of the exterior wall color steel plate; (2) After determining the structural dimensions of the exterior wall color steel plate, cut the exterior wall color steel plate, sandwich layer, and veneer layer materials used, and use a bending machine to bend the exterior wall color steel plate according to the size requirements; (3) The two ends of the color steel plate on the exterior wall are bent into a male side and a female side, wherein the male side includes an upper side and a lower side, and an inner concave opening is formed between the upper side and the lower side through an oblique side and a vertical side; the female side includes a first step, a second step, a middle side and a lower bottom from top to bottom, the middle side enters the inner concave opening, and the lower side abuts against the lower bottom, the second step enters the inner concave opening, and the upper side abuts against the first step; (4) Pre-process the sandwich layer. If the sandwich layer is made of rock wool, adjust the direction of the rock wool fibers; (5) spraying adhesive on the exterior wall color steel plate of step (1) and the sandwich layer of step (4), and assembling them; (6) Paste the veneer layer, and pass the composite wall panel through the crawler line, heat and compact it to make the glue completely solidify; (7) Use foamed polyurethane to seal the tongue and groove on both sides of the board to complete the product.

[0010] In the step (1), the thickness of the exterior wall color steel plate is 0.5-0.75 mm; and the bending height H is 30-80 mm.

[0021] It is further provided that the male edge 4 in the present embodiment 1 includes an upper edge 41 and a lower edge 42, and an inner recess 45 is formed between the upper edge 41 and the lower edge 42 by means of a bevel edge 43 and a vertical edge 44; the female edge 5 includes, from top to bottom, a first step 51, a second step 52, a middle edge 53 and a lower bottom 54, and the middle edge 53 is a raised portion; when connected, the middle edge 53 enters the inner recess 45, and the lower edge 42 abuts against the lower bottom 54, the second step 52 enters the inner recess 45, and the upper edge 41 abuts against the first step 51, thereby realizing the connection between the composite wall panels.

[0022] The method for producing the novel socket-and-spigot steel plate composite wall panel in this embodiment 1 comprises the following steps: According to the requirements of the project structure design and architectural design, select the appropriate type and thickness of the exterior wall color steel plate 1. The exterior wall color steel plate 1 in this embodiment 1 is a small corrugated color steel plate with a thickness controlled at 0.5mm-0.75mm. Determine the bending height H of the exterior wall color steel plate 1. The bending height of the wall panel is controlled at 30mm-100mm. Figure 2 .

[0023] (2) After determining the structural dimensions of the exterior wall color steel plate 1, cut the materials of the exterior wall color steel plate 1, the sandwich layer 2, and the veneer layer 3, and use a bending machine to bend the exterior wall color steel plate 1 according to the size requirements, such as Figure 3 .
