Multi-curvature ceiling structure in tall and large space and its construction method

Abstract

The invention relates to the technical field of decorative ceiling construction, and discloses a large-space multi-curvature ceiling structure and a construction method thereof. The large-space multi-curvature ceiling structure is suspended on the lower part of a steel-structured truss, the steel-structured truss includes a hollow ball at the joint and lower chords fixedly connected with the hollow ball, the lower chords are fixedly connected with the hollow ball, and the ceiling structure includes a hoop assembly located on the lower part of the hollow ball, a keel skeleton detachably connected with the hoop assembly, and a decorative panel suspended on the lower part of the keel skeleton; the hoop assembly includes a horizontally arranged lifting frame support located under the hollow ball, and the lifting frame support is connected and fixed to the lower chords around the hollow ball through a connecting hoop; and the decorative panel is formed by splicing a plurality of unit plates, the unit plates include lifting outer frames and decorative plate strips spliced on the lower parts of the lifting outer frames, the lifting outer frames are arranged on the lower part of a secondary keel in a hung mode through an adjusting assembly, and the decorative plate strips are aluminum honeycomb plates. The large-space multi-curvature ceiling structure has the advantages of detachable connection, convenient, quick and high-efficiency construction and good connection reliability.

Description

technical field [0001] The invention relates to the technical field of decorative suspended ceiling construction, in particular to a high and large space multi-curvature suspended ceiling structure and a construction method thereof. Background technique [0002] The application of suspended ceilings in decoration construction is becoming more and more common, not only in the field of home decoration, but also in the interior roof decoration of large public places. More and more suspended ceiling structures are used. higher. [0003] At present, there are more and more buildings with long-span steel structure trusses or spherical grids as the roof system. When carrying out ceiling construction under tall and large space steel structures, it is difficult to construct large-span steel structure trusses with complex structures. It is difficult to design and realize various shapes, especially for multi-curvature ceiling structures. There is no effective technical means for roof ...

AI Technical Summary

Problems solved by technology

[0007] The technical problems to be solved are: most of the ceiling construction under the existing steel structure roof is welding, the site work is heavy, it is difficult to realize the curved surface design, the construction is difficult, and the construction quality is difficult to control; the connection stiffness under the spherical joint is poor, and the positioning accuracy Poor, prone to installation deviation
