Color steel sandwich panel knowledge manual
Processing of color steel sandwich panels, storage and handling of color steel sandwich panels:
Color steel sandwich panels should be kept as factory-packed as possible before installation and should be stored indoors. If it is stacked outdoors, the stacking place should be flat. There should be no water accumulation and there should be no lifting equipment and heavy objects in the sky. The height of the wooden mat under the board is 20cm. The soft material should be placed between the board and the board. The panels are placed together and each panel should have an easily identifiable panel label and cover the rain tarpaulin. Temporary enclosures shall be provided at the stacking site to prevent unnecessary damage to the panels caused by personnel walking.
For the installation of color steel sandwich panels, the installation of curtain wall panels generally uses movable scaffolding. When ensuring the bearing capacity of construction scaffolding, it is also necessary to consider:
(1) the distance between the curtain wall surface, the working surface and the axis;
(2) Find the spacing and position of the control points against the reference surface, pay attention to the visibility;
(3) Find the spacing of the mounting angles against the reference surface;
(4) the level difference between the control and the elevation;
(5) The vertical distance from the building and the distance from each floor.
When lifting the sheet, lift both ends at the same time to avoid damage to the surface oxide film or coating. When installing the wall panel, only one board can be lifted at a time. The special fixture provided by the manufacturer should be used to lift the wall panel at 2 points in the longitudinal direction of the wall panel. It should be carried out slowly during the lifting process. It should be controlled by the wind rope to avoid bumping with the installed wallboard. The protruding parts of the scaffold are wrapped with soft materials.
There are two main ways to fix the sandwich panel:
One is that the self-tapping screws are directly fixed to the wall sub-structure through the wall panel; the other way is that the self-tapping screws are indirectly connected to the wall sub-structure through the connecting member.
Curtain wall panel installation accuracy:
The verticality of the façade is 2mm, the surface flatness is 3mm, and the joint straightness is 0.5mm. The installation should be strictly carried out according to the technical manual provided by the factory.
Care and maintenance of color steel sandwich panel curtain wall The curtain wall system must be regularly cleaned and maintained. Generally, regular inspections are carried out at least once a year to identify potential problems, maintain their aesthetic appearance and prolong service life. When cleaning the surface, care must be taken not to cause surface scratching. Avoid bleaching ingredients and abrasive-containing washing liquids, steel balls, grinding tools, etc. At the end of washing, rinse the surface with clean water from top to bottom.
If the surface of the wall is damaged, it should be repaired in time. The bottom layer treatment is mainly composed of the bottom layer cleaning, degreasing, repairing the top defects, and the putty to find the equal process. To ensure the top level, the putty should be scraped at least twice. Brush the primer before applying the coating. The finish should be brushed at least 2 times. After each coat of dry paint, it should be treated with a combination of putty and sandpaper, and wipe the float on the paint film with a damp cloth, then brush it again. Coating finishing includes smoothing, polishing and other processes. When the surface layer is polished, water sandpaper should be used. When polishing, clean the surface with a soft cloth.
