Installation steps of A588 weathering steel plate

Installation steps of A588 weathering steel plate:

Check and accept the corroded steel plates and U-shaped grooves before installation, mainly to check whether the specifications and quantities are correct; whether the processing accuracy and the opening position of the U-shaped grooves meet the installation requirements; make sure that the quality of the materials is excellent.

The first thing to do is the installation of the U-shaped groove. This process is the precise positioning after the installation of the keel. The excellent installation quality can ensure the flatness and overall quality of the rusty steel plate installation. Use a level and a meter ruler to level, and usually mark the position of the horizontal line on the outside of the mullion. The position of the middle seam of the plate should be determined according to the design and actual construction conditions, and a horizontal line is placed between the two vertical lines on the horizontal frame.

The vertical grid line of the vertical frame of the hanging mullion at the top of the curtain wall shall be carried out after the installation and adjustment of the curtain wall keel. Normally, the corner position on the right side of the curtain wall plane starts as a grid line, and the grid is projected on the mullion according to the design. Fix and weld the U-shaped grooves on the mullion one by one according to the horizontal line and the vertical grid line that have been played, check the level and verticality with a spirit level and a line hammer, and then fully weld on the mullion, clean up welding slag, brush anti-corrosion rust paint.

After the U-shaped groove is installed, the panel is installed. The installation of the corroded steel plate is mainly to first fix the Φ8 steel pins on the left and right sides of the corroded steel plate panel with the installed U-shaped groove hole, benefiting from the processing and installation of the U-shaped groove in the early stage. The quality control system of the current panel installation only needs to be mortised and tenoned to naturally meet the quality requirements of horizontal and vertical, and the surface is flat. After fine-tuning within a certain range, the upper end of the steel plate can be fixed with bolts; the panel is installed from bottom to top. The rusted steel plate on the upper side presses the upper screw bolted part of the lower steel plate, making it concealed to form a seamless overall effect with no welding, no glue seams, and no bolts on the surface.
