hidden trouble of curtain wall

Structural adhesive and sealant and other existing problems and solutions
After years of use, the curtain wall will exceed its warranty due to man-made or natural reasons. The glue on the curtain wall will be aging, bubbling and cracking. Then it will lose its due cohesiveness, and the curtain wall will become loose or deformed. Curtain wall performance will decline, and there may even be air leakage, water leakage and poor sound insulation effect. To solve this kind of problem, the performance of air tightness, water tightness and wind resistance should be strictly required at the same time of many experiments. The glue of the key part of the curtain wall should be sampled for many times, and measures should be taken in time when unqualified, such as removing the original glue, refilling the glue after cleaning, or you can come up with new transformation methods to solve the problem.

Problems and measures in metal objects of curtain wall
The hardware of the modern curtain wall will be deformed, rusted or damaged when it is beyond the use year or when it is not used. These should be paid attention to, otherwise there will be the occurrence of shedding and other situations, easy to cause harm. When discovering the phenomenon such as deformation of hardware, it is necessary to find out the cause of damage, and check whether the connection of relevant objects also appeared damage. If the thickness of the connector is not up to standard and the screw slips, it is necessary to take timely measures. Replace components with the same brand and specifications of materials. In the replacement should also pay attention to check the surrounding components, and the replacement of hardware to fully comply with the latest national standards and specifications.
Solution of leakage problem
Curtain wall, doors and curtain glass window or awnings, etc., are focused on the leakage of rainwater to carry out a detailed inspection and put forward certain countermeasures. For the top of curtain wall, waterproof treatment has two kinds of eave treatment and eave sealing treatment. The glass curtain wall of the interior ceiling is suspended on the main structure, and many times there will be a certain gap with the main structure. In the building without suspended ceiling, the curtain wall and suspended ceiling can be treated without consideration. Many people use light materials such as wood or metal as window sills. The treatment of the bottom Angle depends on how the design structure is, if the design is different, the treatment method will be different, but the treatment method is different but it needs to be decorated and waterproof. The leakage of curtain wall structure in addition to the engineering receiving mouth, there are also the possibility of failure caused by sealant.
