1. Measure and set the line, according to the on-site baseline, set the line after the check is correct. Use theodolite to determine the vertical grid bus bars on the outer surface of the aluminum-plastic awning, and use the steel wire on the fixed steel bracket as the marking control line to release each division line.
2. Use a spirit level and standard steel tape to measure the horizontal grid points of the aluminum-plastic awning on the steel wire line and mark them.
3. After setting the line and positioning, check the control positioning point regularly to ensure its division is in the correct position
4. Fix the connecting piece with the embedded piece on the main structure. When no embedded iron parts are embedded in the main structure, expansion bolts can be drilled on the main structure to fix the connecting iron parts.
5. Use rivets or bolts to fix the aluminum-plastic panels on the steel frame piece by piece according to the construction drawings. Leave 10～15mm seam between the board to adjust the installation error. When the aluminum-plastic panel is installed, the deviation between left and right, up and down should not be greater than 1.5 mm.
6. After cleaning the surface of the aluminum-plastic panel and frame with a detergent, immediately place a sealing strip or weatherproof tape in the gap between the aluminum panels, and then inject materials such as silicone weather-resistant sealant. The injection should be full and not there are voids or bubbles.
7. The closing treatment can use metal plates to cover the end of the wall panel and the keel.
8. Inspection
