There are cross-overlaps between GRG hanging plates, and the lighting system is dispersed, affecting the visual illuminance in the public area and the light irradiation is not uniform enough. Moreover, the pipelines in the suspended ceiling are arranged in a tiled manner, often seriously crossing the structural components and lighting fixtures of the suspended ceiling, resulting in insufficient space height in the public area, which is not conducive to later use, maintenance and repair, and the problem of integrated utilization is not considered.
