The overall appearance of the exterior wall rock wool board must be aesthetically pleasing, so that there cannot be too much deviation between the boards.
If every error is local, then the higher the structure, the more uneven the structure will be.
Therefore, the construction process of the exterior wall rock wool board is very strict, so preparation before construction is even more important.
Due to the different points that need to be paid attention to in different stages of construction, the preparation work for each project stage can be divided in detail according to its nature.
Among them, pre construction inspection preparation is an important category that cannot be ignored.
Firstly, when preparing materials and equipment for the construction site, check the appearance and ensure that they are intact and undamaged.
When observing the surface, pay attention to whether the color is uniform. Good rock wool board has a uniform color distribution, appearing yellow with no obvious slag inclusions. Regarding the quality inspection of rock wool board, certain quality inspection standards should be followed, including testing the bulk density of rock wool. The bulk density of rock wool board determines its structural density, and the higher the density, the less likely it is to deform.
The national regulation stipulates that the deformation shall not exceed 10%; Rock wool also has good moisture resistance. The national standard is that the compressive strength should not be less than 40KPa to ensure its waterproofness; The fire resistance of rock wool must meet the standard, which is one of the key qualifications. Materials and equipment that comply with contract specifications. Exemption from inspection for products with original factory qualification certificate test report or recognized organization inspection certificate.
Moreover, the pre construction inspection should also include the firm installation of construction specific scaffolding and the passing of safety inspections.
The spacing between scaffolding poles, horizontal poles, walls, and corners should meet the construction requirements.
Thoroughly inspect the safety protection of construction personnel. Operators should wear personal protective equipment to protect occupational health and pay attention to construction safety.
