How to deal with the problem of water seepage and leakage in U-shaped glass curtain wall?

1. In the design, the design structure of the curtain wall waterproof device is mainly considered. The isobaric principle is used to set the isobaric cavity and special pressure introduction hole on the curtain wall aluminum profile, so that the pressure in the isobaric cavity is balanced with the external pressure through special pressure, and the pressure difference is moved to the indoor side that cannot be exposed to rainwater.

2. Removing a small amount of water in the isobaric cavity between the glass, aluminum profile and aluminum buckle is one of the effective ways to drain the water outside the curtain wall into the curtain wall through a small gap, and it is also one of the effective ways to remove a small amount of water in the isobaric cavity between the glass, aluminum profile and aluminum buckle.

3. In the design, water collection pipes and drainage pipes can also be set on the U-shaped glass curtain wall to collect water entering the curtain wall accessories at the same time, and drain the drainage pipe into the designated drainage hole indoors. This is another reliable water control method.

4. Select high-quality structural silicone sealant, weather-resistant silicone sealant, and wall glue, strengthen inspection, and prevent expired use. When choosing high-quality float glass, the glass must be edge processed, and the standard scale failure of the glass must meet the specification requirements.

5. Pay attention to controlling the use environment of the sealant, and stop the outdoor construction of weather-resistant silicone sealant on rainy days. The structural adhesive construction workshop is required to be clean and dust-free, the indoor temperature should not be higher than 27℃ (different brands of structural adhesives have different functions and slightly different requirements for indoor temperature), and the relative humidity should not be less than 50%.
