Glass maintenance
The important part of the curtain wall is glass, and glass is a wearing part, so management and protection are very important.
Wide circulation of air in the place of preservation is necessary. Especially in the high temperature and cycle temperature cycle should pay more attention. If the conditions do not allow them to be stored indoors, they should be covered with tarpaulins or plastics to prevent wind-blown rain and inflowing water, and the hoods should be opened regularly to check for condensation.
The glass must be covered with an opaque protective cover, and must never be stored directly under the sun. Various types of glass should be placed upright at an angle of 5 ° -7 ° to the vertical and leaned against a solid straight wall. The top and bottom edges of all glass should be cushioned with oil felt, and separated with protective cardboard or other oil felt. If the glass is lying flat, the surface must be covered with oil felt to prevent dust, grit glass or other contaminants.
Protection during construction. In the construction, usually use bright flags, decorative ribbons, etc. hanging near the glass or attached to the front of the window frame, side post or window sill to mark this is the space where the glass is installed. Never let the rope directly touch the glass, and do not let the mark or paint directly draw on the glass surface. If welding, cutting sandblasting or other construction techniques that may damage the glass are used near the glass, you must apply plywood or plastic The boards act as a tight barrier to prevent them from affecting and damaging the glass.
Node maintenance
The curtain wall node is the main accessory connecting the curtain wall to the floor. For anti-corrosion, surface treatment must be carried out. Generally, the surface of A 3 steel is galvanized, and the surface is coated with anti-rust iron red primer after installation. The joints that are not sealed and repaired on the floor slab can be inspected at any time. If the corrosion is found, it can be partially polished and then painted. Floor slabs can be inspected regularly (times every two years). Local inspection, such as full inspection if problems are found, and antiseptic treatment.
