This project uses galvanized steel gutter drainage, and the connection between the two sections of gutter is butt welding.
Trench butt welding. Before butt jointing the gutter, polish the cutting mouth cleanly, and pay attention to the gap between butt welds not more than 1mm when butt jointing, spot welding first, and confirm that the requirements are met before welding. To improve construction efficiency, several sections of gutter can be assembled together on the ground and then installed, which can greatly reduce overhead work and improve the quality of gutter splicing.
Open water hole. After installing a section of gutter, first drill a few holes in the middle of the designed drop hole location to avoid water storage in the gutter, which will have an impact on the construction. After the installation of the corresponding part of the gutter plate, you must open the water hole in time. Formal falling water holes with hollow drill cutter or cutter openings.
(D) wall panel installation
The wall panel is in principle constructed with tooled external mobile aluminum tube scaffolding or simple hangers. Installation should pay attention to the horizontal and vertical direction of the operating deviation, to ensure that the horizontal and vertical, while installing the upper wall panels on its bottom wall purlin with square wood under its support pad and review the. Before installing the exterior wall panel, first install the wall system of the upper entrance flooding, window door side flooding and the intersection with the brick wall at the table degree edge, after the wall panel is installed and then install the lower entrance flooding edge and yin, Yang package corner plate.
(E) Painting construction
After the welding of the steel frame is completed, the painting construction team will enter the site for painting. Before painting, the components must be cleaned and polished to ensure that the weld seam is smooth. Then primer with anti-rust primer and top coat after 24 hours. Other construction processes are the same as the factory painting process.
(F) Door and window works
After the window and door opening is formed, the window and door construction team should review the size of the hole for the site and make the windows and doors according to the actual measured data. Install according to the order of window frame first and then window sash. When the gap between the window frame and the hole is large, the window should be filled with foaming agent before gluing. Glass glue should be applied in place and evenly to ensure good sealing and viewing quality.
