Large-span mesh suspended ceiling and its installation method

Abstract

The present invention aims at the problem that the exposure of the roof truss and support system of the open daylighting roof in the existing public buildings affects the aesthetic effect of the large space, and the added decorative ceiling is limited by the force of the roof truss supported by the suspenders, and discloses a large The span mesh suspended ceiling and its installation method include at least one mesh unit. The mesh unit includes a mesh skeleton and two curved panels arranged on the mesh skeleton. The two curved panels protrude outward to form a hollow structure. The hollow setting can reduce the weight so that the mesh unit can be safely and reliably suspended under the cable net structure. The transfer layer transfers the gravity of the mesh ceiling to the form of the roof truss structure, ensuring that the roof truss is not stressed. The invention can form a mesh suspended ceiling of any shape, and has the advantages of wide application and beautiful appearance.

Description

technical field [0001] The invention belongs to the field of building decoration ceilings, in particular to a large-span mesh ceiling and an installation method thereof. Background technique [0002] The roof of this large shopping mall adopts a double-layer open truss system, with fixed trusses on both sides and openable trusses in the middle. The openable roof truss in the middle cannot bear the force, and a large LED screen needs to be installed in the mesh ceiling, which is extremely difficult to construct. The metal mesh ceiling of this project has a long span of 70m and a short span of nearly 30m. At the same time, a circular LED display with a diameter of 22.4m needs to be installed under the roof truss. [0003] The installation of the existing large-span suspended ceiling usually adopts the method of fixing the suspension rod. The steps are: (1) directly hang the mesh suspension ceiling on the steel structure roof truss with the suspension rod; In order to reduce ...

AI Technical Summary

Problems solved by technology

[0005] 1. The load of the mesh ceiling is all applied to the roof truss. Although the structural force is simple and clear, the external load that the steel structure roof truss can bear is limited. The entire mesh ceiling is hung on the roof truss, and a transfer layer is set in the middle. Obviously If the maximum load that the roof truss can bear is exceeded, the steel structure roof truss needs to be reinforced. Therefore, the installation steps are quite cumbersome, and the engineering workload is large, which affects the construction period.

[0006] 2. Exposure of the suspenders to the line of sight will affect the beauty of the entire shape and fail to meet the original design requirements

[0009] Most of these projects use special roof steel structure systems for visual considerations, with different shapes. The original roof truss of this project is designed to be openable. This part cannot bear external forces, and the fixed roof truss can only bear a small Part of the external load cannot support the weight of the entire metal grid ceiling. Therefore, the support of the grid ceiling has become a major problem in the design of the scheme
