Steel cable supporting net for large-span net shaped ceiling system

Abstract

The invention provides a steel cable supporting net for a large-span net shaped ceiling system, and aims at solving the problems that the exposed house frame and supporting system of the open type light roof in the existing public building influence the artistic effect of the large space, and the added decorative ceiling is limited by the stressing of the lifting rods supporting the house frame. The steel cable supporting net comprises a plurality of steel cables and a plurality of adjustable length mechanisms, wherein the steel cables are knitted into a net shape; the end parts of the steel cables are arranged between structure ring beams through the adjustable length mechanisms. According to the steel cable supporting net, the gravity of a net shaped ceiling is transferred to the structural ring beams, thus the form of transferring the gravity of the net shaped ceiling to the house frame structure through a ceiling and a conversion layer in the prior art can be replaced, and the house frame is free of stressing; a plurality of clamp connecting parts for suspending the net-shaped ceiling are arranged on the steel cables; the knitting direction of the steel cables are corresponding to the style direction of the net-shaped ceiling, and therefore, the steel cable supporting net can be hidden above the net-shaped ceiling, and the problem that the lifting rods cannot be hidden in the traditional scheme can be solved.

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
