Ceiling system applicable to large-span space steel structure and construction method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of large-scale public building space steel structure roof ceilings, in particular to a ceiling system and construction method suitable for large-span space steel structures. Background technique [0002] In the past ten years, with the development of my country's economy and the acceleration of urbanization, the application of long-span spatial structures has developed rapidly. At present, it has been widely used in large-scale transportation, culture, sports, exhibitions and other public facilities in China. [0003] The complex roof structure of long-span space is generally in order to show its own structural beauty and save costs, and in the past, it was rarely suspended. However, with the expansion of economic and cultural construction needs, space curved grid roof structure ceilings have begun to appear in China in recent years. [0004] The space steel structure roof ceiling needs to solve the problem...

AI Technical Summary

Problems solved by technology

[0007] In view of the shortcomings of the prior art above, the purpose of the present invention is to provide a ceiling system and construction method suitable for large-span space steel structures, so as to solve the problem that the ceiling structure in the prior art must be welded with the lower string ball of the grid frame, It does not meet the requirements of green construction, the system structure is complex, and it is inconvenient to manufacture, install, and maintain; the keel structure and aluminum panel system cannot be connected with the mature ceiling standard series in the existing market, requiring special manufacturing, and the cost is high.
