Embodiment 1
[0035] Embodiment 1: as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a prestressed construction method of a cable-stayed grid structure is carried out in the following steps:
[0036] (1), reticulated shell installation:
[0037] First set up the scaffolding 1 in the whole hall, and set the V-shaped brace 2 in the scaffold 1. The upper part of the scaffold 1 is provided with the reticulated shell 3, and the reticulated shell 3 is supported and positioned by the V-shaped brace 2; The V-shaped brace is composed of 5 evenly distributed V-shaped braces 2, and the two sets of V-shaped braces are respectively distributed at both ends of the scaffold 1, and the inner side of each group of V-shaped braces is provided with a single brace 4 that is distributed downwards. The single root support 4 is symmetrically distributed;
[0038] (2) Vertical hoisting of the mast in sections:
[0039] The ma...
Embodiment 2
[0054] Embodiment 2: A kind of construction method of cable-stayed grid structure prestressing, carries out according to the following steps:
[0055] (1), reticulated shell installation:
[0056] First set up the scaffolding 1 in the whole hall, and set the V-shaped brace 2 in the scaffold 1. The upper part of the scaffold 1 is provided with the reticulated shell 3, and the reticulated shell 3 is supported and positioned by the V-shaped brace 2; The V-shaped brace is composed of 5 evenly distributed V-shaped braces 2, and the two sets of V-shaped braces are respectively distributed at both ends of the scaffold 1, and the inner side of each group of V-shaped braces is provided with a single brace 4 that is distributed downwards. The single root support 4 is symmetrically distributed;
[0057] (2) Vertical hoisting of the mast in sections:
[0058] The mast 5 is divided into 5 sections, the mast 5 is pre-assembled first, and after the assembly is qualified, the cra...
Embodiment 3
[0073] Embodiment 3: A kind of construction method of cable-stayed grid structure prestressing is carried out according to the following steps:
[0074] (1), reticulated shell installation:
[0075] First set up the scaffolding 1 in the whole hall, and set the V-shaped brace 2 in the scaffold 1. The upper part of the scaffold 1 is provided with the reticulated shell 3, and the reticulated shell 3 is supported and positioned by the V-shaped brace 2; The V-shaped brace is composed of 5 evenly distributed V-shaped braces 2, and the two sets of V-shaped braces are respectively distributed at both ends of the scaffold 1, and the inner side of each group of V-shaped braces is provided with a single brace 4 that is distributed downwards. The single root support 4 is symmetrically distributed;
[0076] (2) Vertical hoisting of the mast in sections:
[0077] The mast 5 is divided into 5 sections, the mast 5 is pre-assembled first, and after the assembly is qualified, the cr...
