The installation of color steel sandwich panels generally adopts movable scaffolding. When ensuring the carrying capacity of the construction scaffolding, it is also necessary to consider:
(1) The distance between the curtain wall, the working surface and the axis;
(2) Find out the spacing and position of the control points against the reference plane, pay attention to visibility;
(3) Find the distance of the installation angle against the reference surface;
(4) The level difference with the control elevation;
(5) The vertical distance from the building and the distance from each floor.
When handling the board, both ends should be lifted at the same time to avoid damage to the surface oxide film or coating. When installing the wall panel of Hefei Color Steel Sandwich Panel, only one panel can be lifted at a time. The special fixture provided by the manufacturer should be used to lift the wall panel at 2 points along the length of the wall panel. The lifting process should be carried out slowly and controlled with wind ropes to avoid collision with the installed wall panels, and the protruding parts of the scaffold should be wrapped with soft materials. There are two main ways to fix the color steel sandwich panel: one is to directly fix the self-tapping screw through the wall panel to the wall substructure. The other method is self-tapping screws, which are indirectly connected to the wall substructure through connectors. The installation accuracy of the curtain wall panels: verticality of the verticality of 2mm, surface flatness of 3mm, and joint flatness of 0.5mm. The installation should be strictly implemented in accordance with the technical manual provided by the manufacturer.
The curtain wall system must be cleaned and maintained regularly, and routine inspections are generally carried out at least once a year to find potential problems, maintain its beautiful surface and extend its service life. When cleaning the surface, you must be careful not to scratch the surface, avoid using bleaching ingredients and detergent containing abrasives, steel balls, abrasive tools, etc., and rinse the surface with clean water from top to bottom at the end of the washing. If the wall surface is damaged, it should be repaired in time. The bottom layer treatment mainly consists of cleaning the bottom layer, removing oil, repairing top defects, and scraping putty. To ensure the top level, the putty should be scraped at least twice. Before applying the coating, the primer should be brushed first, and the topcoat should be brushed at least 2 times. After each topcoat is dry, it should be treated with replenishing putty and sandpaper polishing, and wipe off the floats on the paint film with a damp cloth, and then apply it again. Coating dressing includes smoothing, polishing and other processes. Water sandpaper should be used when polishing the surface, and a clean soft cloth dipped in sand and wax should be used to wipe the surface when polishing.
