Description

Technical Field

[0001] The utility model relates to the technical field of ceramic middle top plates, in particular to a ceramic middle top plate used for subway interior decoration. Background Art

[0002] With accelerating urbanization and growing travel demand, ceramic decorative panels play a vital role in rail transit systems. They not only improve train performance and reliability, but also reduce braking noise and axle wear, enhancing overall aesthetics and reducing weight. Decorative ceramic panels used in rail transit include alumina, silicon nitride, zirconium oxide, and silicon carbide. These materials exhibit excellent properties, including high temperature resistance, high hardness, high strength, high wear resistance, and high thermal stability, and are already in use.

[0003] As people's requirements for travel comfort continue to increase, the market trend of the rail transit platform decoration industry is also constantly changing. The trend of intelligent and comfortable rail transit platform decoration will become more and more obvious, and environmental protection, aesthetics and acoustic characteristics will be one of the future market demand trends.

[0004] Decorative ceramic panels generally have good fire resistance, but rail engineering is a project that requires durability and fire resistance. When constructing subway projects, enamel panels are generally used for decoration, which cannot guarantee lightweight, and the mounting structure needs to be installed on the wall, and then the ceramic panels are installed on the surface of the mounting structure.

[0005] The existing ceramic panels for rail transit platform decoration have the following main shortcomings: there are many types of ceramic panels used in rail transit decoration, and the specifications of different types of ceramic panels are also different, while the specifications of the mounting structures are the same and are in a fixed state. As a result, when ceramic panels of different specifications are installed on the surface of the mounting structure, the ceramic panels will be difficult to cover the mounting structure, and the mounting structure will be exposed. The exposed part will make it difficult to carry out fireproofing treatment for the subway project, and the stability of the ceramic panels after installation is not high. For this reason, we provide a ceramic top panel for subway interior. Utility Model Content
