Large-span net ceiling system and mounting method thereof

Abstract

The invention belongs to the field of building decoration ceilings and particularly relates to a large-span net ceiling system and a mounting method thereof on account of the problems that the large-space attractiveness effect is affected by the exposure of roof trusses and support systems, and increased decorative ceilings are limited by suspension rod support roof truss stress. The system comprises a cable net structure, a net ceiling and a plurality of snapping sheet connectors. The cable net structure is arranged on a structural ring beam and is woven through a plurality of pre-stress processed steel cables, and the net ceiling is fixed on the cable net structure through the snapping sheet connectors. By means of the system and the mounting method, the net ceiling gravity can be transferred to the structural ring beam through the cable net structure, the form of transferring of the net ceiling gravity to the roof truss structure through the ceiling and a transfer layer in the prior art can be cancelled, and the cable net structure can be hidden above the net ceiling, so that the project quality and the attractiveness of the net ceiling are guaranteed.

Description

technical field [0001] The invention belongs to the field of building decoration ceilings, in particular to a large-span mesh ceiling system and an installation method thereof. Background technique [0002] The roof of a 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 red...

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
