Large-altitude-difference non-planar modeling suspended ceiling structure and construction method thereof

Abstract

The invention relates to a large-altitude-difference non-planar modeling suspended ceiling structure. A switching layer main skeleton is provided with a first-level switching layer assistant skeleton through a first-level connecting rod and a second-level switching layer assistant skeleton through a second-level connecting rod, wherein the first-level switching layer assistant skeleton is lower than the second-level switching layer assistant skeleton; the lengths of the first-level connecting rod and the second-level connecting rod are both not greater than 6000mm; the first-level switching layer assistant skeleton is provided with a first-level light steel keel through a first-level upper hanging rib and a first-level lower hanging rib; the second-level switching layer assistant skeleton is provided with a second-level light steel keel through a second-level upper hanging rib and a second-level lower hanging rib; the first-level light steel keel is lower than the second-level light steel keel; the lengths of the first-level upper hanging rib and the second-level upper hanging rib are both not more than 1000mm; the lengths of the first-level lower hanging rib and the second-level lower hanging rib are both not more than 500mm; the lower ends of the first-level lower hanging rib and the second-level lower hanging rib are connected with the surface layer of the suspended ceiling. According to the invention, the structure is simple, a multi-layer gradual retreating type bearing skeleton structure is adopted, the non-planar display of the surface layer of the suspended ceiling is realized through close joint connection and the construction speed and integral precision are ensured.

Description

technical field [0001] The invention belongs to the technical field of architectural decoration structures and construction methods, and in particular relates to a non-planar suspended ceiling structure with a large height difference and a construction method thereof. Background technique [0002] At present, in long-span public buildings such as airport terminals, station waiting rooms, convention and exhibition centers, and stadiums, the suspended ceilings are all curved and other non-planar shapes to highlight the sense of open space. [0003] However, non-planar ceiling structures often encounter the following two problems: [0004] First, Article 6.1.11 of the "Code for Acceptance of Construction Quality of Building Decoration Engineering" (GB50210-2001) stipulates that when the length of the suspender is greater than 1.5m, anti-support should be set. However, when the height difference of many non-planar ceilings exceeds 1.5m, it is still a difficult construction poin...

Problems solved by technology

However, the glue joint with a width of 16~25mm divides the ceiling surface into different geometric shapes, which seriously affects the continuity and integrity of the ceiling structure
