Embodiment 1

[0015] Such as figure 1 As shown, this embodiment includes the following steps:

[0016] 1. The project adopts structural design software Ansys and Revit data integration, and uses BIM technology to carry out in-depth design;

[0017] 2. Deepen the design, divide the cable into 36 areas according to the BIM result data, extract the processing size, draw the cable body processing drawing, and then cut the material, process and assemble after the design unit agrees;

[0018] 3. In order to facilitate the installation of the cable clamp and protect the cable body. Put wood under the cable body to separate the cable body from the ground, and set up a 0.5m high lattice frame at the cable clamp to facilitate the installation of the cable clamp cover;

[0019] 4. The upper ring cable 4 is laid, and the cable is transported to the site by a reel. In order to avoid the twisting of the cable body when the cable is unfolded, the upper ring cable 4 adopts a horizontal reel. Use a crane...

Abstract

The invention discloses a stadium ultra-large-span hub type double-layer cable structure and a mounting method thereof. The stadium is composed of a steel frame structure, a roof cable net structure and an outer pressing ring horizontal truss, wherein the width of the outer pressing ring horizontal truss is 12-13 m, the outer pressing ring horizontal truss is supported on inner ring vertical steelpipe columns, A-shaped steel pipe columns and outer ring inclined steel pipe columns, the specification of a horizontal pressed truss inner chord is P1600 * 50 mm, the specification of a horizontal pressed truss outer chord is P1200 * 32 mm, the inner ring steel columns are hinged and supported at the tops of concrete stand columns, and the outer ring steel columns are hinged and supported on a 6m elevation concrete structure. By the adoption of the hub type design, long materials and short materials obtained after steel components are cut are utilized to the maximum extent, particularly, the project adopts a structural design Ansys and Revit data fusion technology, the whole process from design to construction is controlled, strict measurement, calculation and control are realized, industrialized production is realized, the length is fixed, so that the measure cost in general similar engineering total cost is greatly reduced, and the cost of labor, materials and the like is saved.

Description

technical field [0001] The invention relates to a super-large-span hub-type double-layer cable structure for a stadium, which belongs to the technical field of construction engineering. Background technique [0002] Large-space public buildings mostly use curved grids and large-span steel structures, and the surface decoration of grids is mostly designed with curved surfaces. The installation and construction method of the complex curved surface network frame reverse method includes the construction of a unit curved surface section and the cross construction of each installation section. Before construction, the finite element analysis software Midas is used to conduct a whole-process simulation analysis of the entire construction process, and optimize the construction plan through analysis. And strengthen or replace the members with higher stress in the construction process analysis. The large bifurcated column and the complex curved grid structure reverse installation con...
