Embodiment 1
[0046] Such as Figure 1-3 As shown, the present embodiment provides a roofing steel structure construction method, comprising the following steps:
[0047] S1. Divide the roof steel structure as a whole, set the G-T axis horizontally, and set 6-25 lines vertically;
[0048] S2. Set the area of the G-M axis * 6-25 lines as the first lifting area 1, and set the area of the M-T axis * 6-25 lines as the second lifting area 2;
[0049] S3. Set the area of lines 14-17 as lifting unit 1 3, set the area of lines 12-14 and 17-19 as lifting unit 2 4, set the area of lines 10-12 and 19-21 as lifting unit 3 5 , set the areas of lines 6-10 and lines 19-21 as lifting unit 4 6,
[0050] S4. Assemble each lifting unit on the corresponding floor into an overall lifting unit, lift the low lifting unit to the height of the high lifting unit, connect the low lifting unit and the high lifting unit as a whole, and then lift the whole to the height of the higher lifting unit At the pla...
Embodiment 2
[0072] Furthermore, this embodiment provides a roof steel structure construction system, in which the steel structure is a roof steel structure with a spatial grid structure, the section shape of the roof steel structure is arc-shaped, and the maximum installation height is 36.0m, the maximum height is 20.2m, and the support form is multi-point support on the lower chord;
[0073] The overall roof steel structure is set with G-T axis horizontally and 6-25 lines vertically, among which, the area of G-M axis * 6-25 line is the first lifting area 1, and the area of M-T axis * 6-25 line is the second lifting area 2;
[0074] Among them, upgrade the floors below Area 1 with an elevation of -0.150m in the range of 12-19 lines, the concrete floors of 9.850m in the range of 10-12 lines, 19-21 lines, and the 7-10 lines, 21-24 Concrete floors with an elevation of 15.950m in line range; upgrade the floors below Area 2 to 9.850m elevation in the range of 10-21 lines, and -0.150m elev...
