Description

Technical Field

[0001] The utility model relates to the technical field of composite plates, in particular to a bendable aluminum composite plate structure. Background Art

[0002] Architectural decorative composite panels are a type of material made of metal combined with core materials. The production process involves chemical processes, using metal materials (aluminum is more common) as surface materials and polyethylene plastic or mineral fillers as core materials. After being gradually processed on specialized aluminum-plastic panel production equipment, this composite material is formed. Aluminum composite panels have a wide range of applications. They can be used not only for ceilings, walls, partitions, doors and other decorations, but also for making furniture and display cabinets. In the outdoor field, aluminum composite panels are often used in outdoor curtain walls, billboards and engineering decorations due to their good weather resistance and long-term use without fading. At the same time, aluminum composite panels also have excellent flatness and surface flatness, which are very suitable for advertising production, making the advertising effect more eye-catching and outstanding.

[0003] When aluminum composite panels are used in outdoor curtain walls, billboards, engineering decoration and other fields, curved decorative surfaces are often encountered. Therefore, when installing aluminum composite panels, multiple panels need to be cut and combined for use. The curved decorative surface is achieved by combining multiple aluminum composite panel planes. However, this method is aesthetically fragmented, and the cutting and reassembly and installation of aluminum composite panels is not only time-consuming and labor-intensive, but also increases the cost. Therefore, the present application proposes a bendable aluminum composite panel structure to solve the above problems. Utility Model Content

[0011] Preferably, the upper metal plate and the lower metal plate are aluminum plates.

[0012] Preferably, the core material is integrally formed with the upper metal plate and the lower metal plate.

[0013] (III) Beneficial effects

[0014] The beneficial effects of the utility model are:

[0015] The bendable aluminum composite panel structure cuts off the core material and the upper metal plate on one side through the provided forming groove, leaving only a lower metal plate in the middle, and then the lower metal plate is bent and formed by extruding the two sides of the composite panel body to match the curvature of the locations where it needs to be installed on outdoor curtain walls, billboards, engineering decorations, etc. This ensures beautiful appearance after installation, and compared with the curved surface installation achieved by cutting and then combining the installation, it saves costs and improves installation efficiency.
