When will the building curtain wall be tested and repaired?  

1. One year after the completion and acceptance of the curtain wall project, a comprehensive inspection of the curtain wall project will be carried out, and then an inspection will be carried out every five years.；  

2.The curtain wall as a whole should be deformed, misplaced and loose. If so, the corresponding hidden structure of the curtain wall should be further checked. Whether the main load-bearing components, connecting components and connecting bolts of the curtain wall are damaged, whether the connection is reliable, and whether there is corrosion.  

3.Whether the glass plate, metal plate and stone are loose and damaged, especially whether there are cracks and defects on the surface of the stone；  

4.Does the sealant have damage phenomena such as degumming, cracking, foaming, pulverization, shedding of the sealing strip, and aging?  

5.Whether the opening and closing part is flexible, whether the hardware accessories are out of order or damaged, whether the installation bolts or screws are loose and failed；  

6.Is the curtain wall drainage system smooth?；  

7. After the completion and acceptance of the prestressed vertical pole and cable structure curtain wall project, it must be inspected and adjusted every three years.  

8.After 10 years of use in the curtain wall project, the bonding properties of silicone sealants in different parts of the project are sampled and inspected every three years.  

9.When the curtain wall is hit by a strong wind, a comprehensive inspection of the curtain wall should be carried out in time, the damaged components should be repaired or replaced, and the curtain wall project of the prestressed or cable structure should be fully pre-tensioned inspected and adjusted.  

10.When the building curtain wall encounters disasters such as earthquakes and fires, professional and technical personnel in mountainous areas should conduct a comprehensive inspection of the curtain wall and formulate a treatment plan in time according to the degree of damage.  

How to repair and replace the glass damage of the building curtain wall?  

1.The removal of broken curtain wall glass and the removal of curtain wall glass are one of the most difficult tasks in the construction of glass replacement. In addition to fully mastering the structure of the original curtain wall, we also have a wealth of work experience. Once the original curtain wall glass is broken, if you accidentally break the glass fragments and other parts of the glass, especially if the glass area is too large, it will be more difficult to remove the curtain wall glass.  

2.Remove the original glass, stick the tape to the surface of the fragile glass to ensure that the glass fragments will not fall off, and gently remove the broken glass from the surrounding area, use a suction cup to remove all the original broken glass from the safety bucket, clean up the fragments around the glass, use a wallpaper knife to remove the sealant around the glass, remove the foam stick from the seam, use a hex wrench to fix the aluminum alloy glass at the seam, four external construction personnel use suction cups to suck the glass, and the three inside also use suction cups to suck the glass out of the glass mouth, go down to the room, and slowly put it down until it is safe to land. The person inside holds the glass in his hand, and the outside is fixed with a hex wrench. The glass is fixed at the joint, four external construction personnel use suction cups to suck the glass, and the three inside also use suction cups to suck out the glass mouth, go down to the room, and slowly put it down until it is safe to land, the person inside holds the glass in his hand, outside The people came in along the window, and the glass was safely transported to the second floor.  

3. Remove the aluminum alloy frame of the broken glass, and use two-component structural glue to bond the glass and the aluminum alloy frame together. The curing time of the structural glue is 2 hours. After the structural glue is cured, the glass surface is removed and safely transported to the construction site.
