Description

Technical Field

[0001] The utility model relates to the technical field of plates, in particular to a corrugated aluminum plate with a multi-layer structure. Background Technique

[0002] The corrugated aluminum plate, also known as profiled aluminum plate or aluminum tile, is a plate formed by using high-quality aluminum alloy plates as the base material through technologies such as roll pressing and cold bending or numerical control bending. Its surface coating often adopts advanced spraying equipment and high-quality coatings to ensure uniform surface color, and has characteristics such as anti-ultraviolet radiation, antioxidant, super corrosion resistance, excellent weather resistance and self-cleaning property.

[0003] In urban public transportation vehicles, such as subways and light rails, since the subway system contains a large number of mechanical and electrical equipment and electronic control systems, such as signal systems, communication systems, monitoring systems, etc., static electricity is generated regardless of time and occasion. It may cause random failures, misoperations or calculation errors when these devices are running, and may even lead to the breakdown and destruction of some components (such as CMOS, MOS circuits, bipolar circuits, etc.). Therefore, anti-static floors are mostly used for the floors inside the subway. However, the anti-static floors are heavy, which additionally increases the energy consumption, and have high requirements for installation operations in order to achieve the expected effect during installation, and the installation process is complex.
