Guangxi Nanning Theatre is a 1,720-seat comprehensive theater. Based on the investigation and study, after the comparison of the plans, the ceiling design of the auditorium reformed the traditional structure and structure, using diagonal joists and prefabricated suspended ceilings. After its completion, it has been widely applied in China. Practice has proved that this type of ceiling can meet the requirements of architectural use and acoustics, with good fireproof performance, simple structure, convenient construction, and can also save materials, lower cost, and have a certain economic effect. The selection analysis, construction practices and effects of this roof structure are summarized below. First, the audience hall roof construction structure and structure selection The auditorium hall area accounts for more than one third of the entire hall surface area, its form and structure of architectural modeling and sound effects have considerable impact, so the theater ceiling structure is to ensure safe use, The key parts of relationship sound effects and architectural art.
