The abnormal sound of aluminum plate dry hanging facade is serious and needs to be analyzed and solved.

This kind of sound is that when the sun shines on the surface of aluminum plate, the temperature rises sharply above 50℃, and the thermal expansion coefficient of aluminum plate itself is very large in metal, and the aluminum plate expands and deforms rapidly at 24* 10E6. The aluminum plate is fixed on the keel steel frame by self-tapping nails, and the transverse deformation causes the aluminum plate and the keel to slide slightly at the fastening point, resulting in vibration sound; Secondly, the thermal expansion coefficient of aluminum plate is 24E6. If the width of the plate is more than 2 meters, the expansion is limited after the two ends are fixed, and the stirring sound generated by extrusion will be generated. Measures: add a flexible gasket between the aluminum plate and keel at the fixed point, and then fix it at one end and slide it at the other end.
