The aluminum facade is out of shape in the hot sun, and the high temperature has little to do with it
The large probability of deformation of aluminum curtain wall is related to the construction process and the thickness of aluminum plate...... First of all, to be sure, it has little to do with the heat, unless there is a major design problem.
From the aluminum plate deformation map provided by netizens, the facade belongs to the splicing of small pieces of aluminum plate, and the process will be complicated. "Deformed aluminum sheets will need to be removed piece by piece and possibly replaced altogether." According to the general statement of the project, the rectification is not small. At present, aluminum plate has become the "face" of many luxury homes, and such a large area of deformation is indeed a bit "eye-catching".
Coincidentally, some netizens broke out the aluminum curtain wall of Hangzhou and luxury homes, and similar deformation occurred, and the "concave and convex surface" of the large pieces of aluminum plate in the sun was very obvious. From the figure, these are large separation aluminum plates, generally used in the east and west sides; The small dividing aluminum plate mentioned earlier is used more in the north and south facades. The former is 3mm thick, while the latter is 2.5mm.
Aluminum plate deformation is actually more complex, for example, like the construction process, aluminum plate has a fold, if the fold size is small, the surface strength is weak, aluminum plate will also occur deformation; There are batches like aluminum plates if inconsistent, there will be color differences, in the sun, it is easy to cause the illusion of 'deformation', but this possibility is less, but in the later process of changing the plate will appear.
Will this deformed aluminum sheet fall if not replaced?
This possibility will basically be ruled out, but the first thing for luxury homes is to deal with the "face project", so it will be adjusted and replaced immediately, otherwise it will be embarrassing.
Rectification suggestions have been issued, and aluminum facade is still the mainstream choice
At the same time as the deformation event of the aluminum facade fermented on the Internet, the two buildings also gave rectification suggestions in the first time. At present, aluminum facade has been widely used in real estate development, the material and construction technology are relatively mature, the above problem is a case, does not represent universal!
The first luxury house wrote in its rectification feedback: We did find that there is a flat aluminum plate in the self-inspection, has given the rectification progress on related issues, in addition to the problematic building, the rest of the building will also arrange self-inspection and rectification, the overall cycle of about 3-4 months.
