The invention discloses a ceiling
system applicable to a large-span space steel structure and a construction method thereof. The ceiling
system comprises a ceiling mounting plate, an adjustable mounting base, a three-dimensional adjustable hoisting tray, a ceiling
joist and a panel, wherein the adjustable mounting base is connected with the ceiling mounting plate through a
fastener and a fixing part rather than
welding, therefore, the traditional grid lower chord ball
welding ceiling method is changed, potential safety hazards caused by overhead
welding can be avoided, green construction is realized, the construction error effect of a three-dimensional adjustable digestive grid lower chord ball can be achieved; meanwhile, the three-dimensional adjustable hoisting tray can rotate in all directions, the structure of a main
joist is adjustable horizontally, can be adapted to the curve change of a space steel structure roof, can absorb deformation and structure mounting errors of a grid structure generated under the action of static and dynamic loads. The ceiling
system disclosed by the invention has the advantages of reliable structure, simpleness in mounting, light weight, no need of wielding, good durability, high economical efficiency and the like and also has great innovation, a high promotion value and strong market competitiveness.
