1. After the materials are transported to the site, they should be stacked according to specifications and installation locations. Square wood should be placed underneath to prevent rain erosion. The stacking height should not be too high to prevent deformation caused by overweight.
2. In order to meet the requirements of the overall construction schedule, the laying of pattern plates is closely connected with the installation of the steel structure. After the anti-corrosion work of the steel beams has been carried out to a certain stage, the pattern steel plates can be laid. The laying sequence is the same as the installation sequence of the steel beams. Group A is installed from 120 to 101 axes, and Group B is installed from 121 to 138 axes.
3. First weld the lifting lugs on the ground on the pattern plate, and use flame to cut the holes for welding seams at the secondary beams and frame beams. The size of the holes is 6mmx12mm, and the interval does not exceed 0.5m.
