Cable Support Mesh for Long-Span Mesh Ceiling Systems

Abstract

Aiming at the problems of the open daylighting roof in the existing public buildings, the exposure of its roof truss and supporting system 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, a method for large space is disclosed. The steel cable support network of the span mesh ceiling system includes several steel cables and several length-adjustable mechanisms. The steel cables are woven into a net shape, and the ends of the steel cables are arranged between the structural ring beams through the length-adjustable mechanisms. The steel cable support net transfers the gravity of the mesh suspended ceiling to the structural ring beam, replacing the form of transferring the gravity of the mesh suspended ceiling to the roof truss structure in the prior art by using the ceiling and the transfer layer, so as to ensure that the roof truss is not stressed. The steel cables are provided with a number of card connectors for suspending the mesh ceiling, and the weaving direction of the steel cables corresponds to the shape of the mesh ceiling, so that the steel cable support net can be hidden above the mesh ceiling, solving the problem of It solves the problem that the boom cannot be hidden in the traditional scheme.

Description

technical field [0001] The invention belongs to the field of architectural decoration ceilings, in particular to a steel cable support net used for a large-span netted ceiling system. 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...

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
