Summary:

The installation of color steel sandwich panels general […]

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, 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. 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. Another way is to indirectly connect the self-tapping screw to the wall substructure through the connector. The installation accuracy of the curtain wall panels: verticality of the elevation 2mm, surface flatness of 3mm, and seam flatness of 0.5mm. The installation should be strictly implemented in accordance with the technical manual provided by the manufacturer.

Care and maintenance of color steel sandwich panel curtain wall
The curtain wall system must be regularly cleaned and maintained, and routine inspections are generally carried out at least once a year to find potential problems, maintain its beautiful surface and prolong its service life. When cleaning the surface, you must be careful not to scratch the surface. Avoid using bleaching ingredients and detergents 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 find equal steps. To ensure the top level, the putty should be scraped at least twice. The primer should be applied before the coating, and the topcoat should be applied at least 2 times. Each finish should be done after the fingers have dried. Repair the putty and sandpaper polishing treatment, and wipe the floating matter on the paint film with a damp cloth, and then paint 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.
