2. Secondary lofting is an important step in prefabrication and installation of rock wool sandwich panels. It is to convert the planning drawing into the center conversion drawing of secondary processing in the factory, and make the standard size panels into different types of wallboard. They are combined to reflect the intention of the program. The standard size steel plate is manufactured and purified in the rock wool sandwich panel factory and assembled in the construction site, which can not only ensure the firmness of the plate, but also accelerate the installation speed of the rock wool sandwich panel.
3. When prefabricating in the factory, according to experience, the gap between doors, windows and joints and the equipment allowance should be fully considered. Avoid scratches, heavy pressure and surface impact in the whole transportation, manufacturing and installation process to prevent irreparable dents and scratches. The plastic protective film on both sides of the purified rock wool sandwich panel can only be removed after the equipment is thoroughly cleaned.
4. Piling before purification of rock wool sandwich panel device shall be carried out after the completion of relevant conditions such as the ground (building) surface of the device. For example, the transportation of large-scale equipment is in place, the adjustment of hidden ground pipelines, and the operation of equipment is basically completed. Setting-out is to mark the horizontal projection of rock wool sandwich panel and the position of doors and windows on the ground.
5, according to the lofting proportion fixed aluminum trough.
6. Set up rock wool sandwich panels, install prefabricated components according to line drawing, and determine adjacent wallboard with fixed inserts between components.
