Familiar with the drawings, carefully review the layout of the color steel plate, the node requirements, the relationship between the color steel plate and the building, the color, filling, basic size requirements of the color steel plate itself, the size and arrangement of the doors and windows in the color steel plate partition, and the type of auxiliary materials and other unknown contents.
The secondary panel drawing is an important step in the prefabrication and installation of color steel plates. It is the intermediate conversion of converting the design drawings into those available for processing in the factory, making standard specification panels into different types of siding, and combining them to reflect the design intent. Figure, and produce standard plates in the color steel plate factory, and assemble them at the construction site, which can not only ensure the firmness of the wall panels but also speed up the installation speed of the color steel plates.
When prefabricated in the factory, according to experience, gaps and installation allowances are considered between door openings, window openings and seams. And during the entire transportation, production and installation process, scratches, heavy pressure and surface impact are prevented to prevent uncorrectable pits and scratches. The plastic protective film on both sides of the color steel plate is only allowed to be removed when cleaning is completed after the installation is complete.
The lay-out work before the installation of the color steel plate should be carried out after the ground (floor) surface is completed, and the main installation work of the interlayer is basically completed when other relevant installation conditions are met, such as the larger equipment has been transported in place, and the concealed ground pipeline has been adjusted. can be carried out. The setting line is to draw the horizontal projection of the color steel plate (50mm wide) and the positions of the doors and windows on the ground. The center line of the upper and lower mangers should be on the same vertical plane, and the error should be within 1.0%, that is, 3mm.
