Application characteristics of Chengdu glass curtain wall

An important part of the curtain wall is glass, and glass is a wearing part, so management and protection are very important. Widespread circulation of air in the place of preservation is necessary. Especially during high temperature and cycle temperature cycles. If conditions do not allow them to be stored indoors, they should be covered with tarpaulin or plastic to protect against wind inflow rain and incoming water, and the hood should be opened periodically to check for condensation. The curtain wall node is the main accessory connecting the curtain wall with the floor slab. In order to prevent corrosion, surface treatment must be carried out, generally for A3 steel to adopt surface galvanizing, and then apply surface anti-rust iron red primer after installation. Joints that are not sealed and repaired on the floor can be inspected at any time, and if corrosion is found, it can be partially sanded and then painted, and if the bolts are loose, re-tightened. , protection during construction. In construction, bright flags, colored ribbons, etc. are usually hung near the glass or attached to the front of the window frame, side posts or window sill to mark the space where the glass is installed. Never allow the rope to come into direct contact with the glass, and do not allow marks or paint to be drawn directly on the glass surface, and if welding, cutting, sandblasting, or other construction processes that may damage the glass are used close to the glass, plywood or plastic sheets must be used as a tight barrier to prevent them from affecting and damaging the glass. First, the open frame glass curtain wall, the frame glass curtain wall is a glass curtain wall exposed on the outer surface of the metal frame frame. It is framed by an aluminum alloy profile of a special section, and the glass panel is fully embedded in the grooves of the profile. It is characterized by the fact that the aluminum alloy profile itself has the dual role of skeleton structure and fixed glass. White-frame glass curtain wall is the most traditional form, the most widely used, and the working performance is reliable. Compared with the hidden frame glass curtain wall, it is easier to meet the requirements of the construction technology level. Second, hidden frame glass curtain wall, the metal frame of the hidden frame glass curtain wall is hidden on the back of the glass, and the metal frame is not visible outdoors. The hidden frame glass curtain wall can be divided into two types: full hidden frame glass curtain wall and semi-hidden frame glass curtain wall, and the semi-hidden frame glass curtain wall can be horizontal and vertical, or vertical and horizontal. The structural characteristics of the hidden frame glass curtain wall are: the glass is on the outside of the aluminum frame, and the glass is bonded with the aluminum frame with silicone structural sealant. The load of the curtain wall is mainly borne by the sealant.
