Description

Technical Field

[0001] This utility model relates to the technical field of subway station interior construction engineering, and in particular to a large-span curved ceiling for subway stations. Background Technology

[0002] Due to its structure, the interior of a subway station requires interior decoration to improve the space and create a more open and transparent effect. Subway stations also need to be equipped with ventilation ducts, water pipes, and various lighting fixtures and electrical installations. These facilities are generally arranged at the edges of the ceiling. Arched ceilings have an open curved surface and are suitable for the placement of auxiliary facilities at the edges. Compared with ordinary ceiling structures, they have an arched structure. Compared with ordinary ceilings, the arched sides are more stable for support or suspension, and also save on construction and decoration materials. For large-span suspended ceilings with curved structures, the actual configuration styles are numerous and the configuration is relatively complex. Existing implementation cases show that a simple configuration is available for large-span curved suspended ceilings in subway stations. Utility Model Content
