Background
Along with the development of economy and the improvement of living standard of people, the pursuit of people for cultural art is higher and higher, in order to meet the demand of people for the cultural art, the urban construction tends to plates of cultural art places, the cultural art places are gradually pulled out in large and medium cities including small cities like bamboo shoots after rain, and the buildings have the characteristics of large space, large span, high requirements on acoustics, optical performance and material impression of indoor building materials, complex shape and the like. Such as: museums, cultural art centers, movie theaters, operas, exhibition centers, concert halls and gymnasiums. At present, GRG (glass-fiber reinforced plastic) modeling of projects such as operas houses, art centers and the like is complex, has oval, special-shaped, irregular and the like, and has large longitudinal and transverse span, the covered space of a GRG modeling suspended ceiling is increasingly large, and the construction difficulty is also increasingly high. The social demand and the construction technology generate great contradiction, so the research on the GRG suspended ceiling structure in the ultra-large space is a necessary trend.
Chinese patent (CN201721227028.4) discloses a GRG ceiling board connecting structure, which comprises GRG ceiling boards, wherein a closing-in is formed between the two GRG ceiling boards, a connecting board is embedded in the closing-in, two connecting rods are arranged on the connecting board at intervals, a base plate is fixed on one side of each GRG ceiling board, and the connecting rods vertically penetrate through the corresponding GRG ceiling boards and the base plates; the backing plate deviates from GRG furred ceiling board one side and is equipped with locking Assembly, locking Assembly includes linkage plate and fastening jib, the upper and lower both ends of fastening jib are equipped with the fixture block, the shaping has the inner groovy in the backing plate, be equipped with thrust bearing in the inner groovy, the connecting plate upper surface is equipped with the rubber pad. The utility model provides a GRG furred ceiling board connection structure that aesthetic property is good, stable in structure and security are high mainly uses plane GRG to hang the installation as leading, does not provide the installation scheme of the GRG furred ceiling of the many curved surfaces of large tracts of land.
Chinese patent (CN201920356566.6) discloses an anti-cracking structure for a special-shaped curved GRG ceiling, which comprises a ceiling framework and a special-shaped curved GRG panel; adopt reinforced structure between the flange limit of dysmorphism curved surface GRG panel, this reinforced structure includes that the stainless steel is worn the silk, is connected through the stainless steel is worn the silk between the adjacent flange limit, from last to setting gradually rubber pad, jointing layer, net fiber cloth back up coat and repairing layer down between the adjacent flange limit, jointing layer and repairing layer are GRG caulking agent, the utility model discloses dysmorphism GRG panel mounting structure can make things convenient for angle regulation, and the workman's of being convenient for construction makes the GRG panel atress even, can effective control GRG panel crack problem.
