Building curtain wall glass repair generally follow the following methods:

　　1. Demolition of broken curtain wall glass

The demolition of building curtain wall glass is a technically difficult task in the replacement of glass. In addition to fully grasping the structure of the original curtain wall, it also requires a wealth of work experience. Because the original curtain wall glass is broken, if you accidentally drop the broken glass fragments and smash the glass in other parts, especially the curtain wall glass with a large glass area, it is more difficult to remove.

　　2. Demolition of the original glass

Paste the surface of the fragile glass with adhesive tape to ensure that the glass fragments will not fall. Then gently remove the broken glass from all around and use a suction cup to remove the original piece of broken glass and put it in a safe bucket. After finishing the debris around the glass, use a wallpaper knife to shovel the sealant around the glass, take out the foam rod in the glue seam, and then use a hex wrench to remove the aluminum alloy glass fixings in the glue seam. The four outside construction workers sucked the glass with a suction cup, and the three inside also sucked the glass with a suction cup. At the same time, they lifted up at the same time, so that the glass mouth slowly slid outwards and downwards into the room until it fell safely. The people inside hold the glass with their hands, and the people outside come in through the window, transporting the glass safely underground.

　　3. Remove the broken aluminum alloy structure

Use two-component glass structural adhesive to bond the glass and aluminum alloy structures together. The curing time of the glass structural adhesive is 2 hours. After the glass structural adhesive is cured, the surface of the glass is removed and transported to the construction site safely.

　　4. Glass installation

Outside construction personnel went up the roof of the building and slid along the rope to the construction site, with the glass top facing out. Construction workers inside and outside sucked in the suction cups, and the inside and outside forces lifted together, the glass went out first on the top, and also went out with the bottom. Hold up and slide to the left, hang the hook of the glass aluminum alloy frame, and fasten the aluminum alloy fixture with a hexagon wrench. Fill the foam joints around the glass with foam sticks, paste the masking with masking paper, use a glass glue gun to drive the glass sealant into the joints, and use a gray knife to compact the joints to make the joints around the glass smooth and smooth. Finish the glass exterior, and the construction workers outside will slide along the rope to the first floor and go up to the top of the building to collect the rope. Check the construction site to ensure that there are no remaining debris and problems left over by the project.
