How should the curtain wall be maintained and maintained?

First, the use life of the curtain wall

According to the service life of various curtain wall data, the service life of curtain wall engineering should be more than 20 years. But in this process must do the right amount of maintenance and repair. The concept of curtain wall service life is divided into two parts, one is physical service life, the other is economic service life. From the technical point of view, the physical life is how many years the current curtain wall project can not be reused; Economic durability life refers to how many years the current curtain wall project may also be used, but from the maintenance and repair of the degree, with the new curtain wall project to replace the old curtain wall project is more favorable. For the curtain wall project, maintenance and maintenance should be carried out once a year, which may increase the use life of the curtain wall.

Two, glass maintenance

The curtain wall is an important part of glass, and glass is easy to damage, so the treatment and maintenance is very important. The curtain wall of the building is composed of supporting structure system and panel, which can have a certain displacement capacity relative to the main structure, and does not share the building envelope or decorative structure that the main structure is affected by. In the construction condition, the glass must be covered with an opaque protective cover, and must not be kept in the sun. Pile up all kinds of glass should be broken with 5 degrees to 7 degrees Angle straight with vertical direction, lean on firm straight wall. The top and bottom edges of all glass should be padded with felt and removed with maintenance board or other felt. If welding, cutting sandblasting or other construction technology that may harm the glass is taken in the place near the glass, plywood or plastic board must be used as a thoughtful isolation layer in order to avoid their influence and even harm the glass.

Three, the curtain wall of the rest

Scrub with solvent. Use xylene, toluene, inorganic alcohol or diethyl ether to remove grease and to keep up with the outdated light materials for scrubbing and bleaching. Be careful not to use too strong acceptor to avoid damage to the sealant fixing the glass.

Four, curtain wall maintenance

1 check. The curtain wall of the building is composed of supporting structure system and panel, which can have a certain displacement capacity relative to the main structure, and does not share the building envelope or decorative structure that the main structure is affected by. One is the name of the inspection: visual appearance of the name of destruction of the scene.

Two is the internal inspection, check whether the glass is damaged, the invention of the damage to replace in time. Check whether the connector is corrupt and loose regularly; Whether the hardware has functional obstruction; Whether the adhesive strip falls off or cracks; Whether the glass is dewy.

Maintenance of device process. The profile name must be pasted with protective tape; Before the glass device must be strictly checked, and clean up the nominal dirt, such as invention cracking must be replaced; Before the glue injection, seriously clean the joint of profiles and glass, eliminate the moisture of the name of glass, individual glue injection should be carried out in the next battle; After glue injection, clean up the residual glue and nominal dirt in time, and repair the defects in time.

3. Use process maintenance. The curtain wall of the building is composed of supporting structure system and panel, which can have a certain displacement capacity relative to the main structure, and does not share the building envelope or decorative structure that the main structure is affected by. Curtain wall engineering should be checked on schedule, such as invention off and infringement should be replaced and repaired in time; When repairing, the damaged place shall be cleaned up. Regular window cleaning machine for cleaning; Repair of nominal scratches using curtain wall paint.

Maintenance of 4 nodes. Curtain wall node is an important accessory connecting curtain wall and building. Contacts must be anticorrosive treatment such as the invention of node connector decay, can be local grinding and then paint; If the bolts are loose, tighten them again.
