At present, the external thermal insulation materials of building exterior wall mostly use on-site composite board or steel pressure profiled steel plate and rock wool. When the profiled steel plate and rock wool composite board are laid on the curtain wall base, although the waterproof and fire-resistant properties are achieved, the bearing effect of the materials is not good; When using steel directly, it is not only necessary to use mortar and other building materials, but also inconvenient for disassembly and assembly, and the service cycle index is low. Next, I will introduce the construction fields in which rock wool sandwich panels can be used.
Sandwich panel is a kind of wall panel commonly used in steel structure construction. It not only has the advantages of small quality, low price, beautiful appearance and convenient installation, but also has good fire resistance and heat insulation performance. However, there are still some shortcomings in the existing sandwich panel: most of the panels are connected with notches, the joint strength is not enough, and it is easy to be damaged by external force, although some products are connected by bolts However, the installation is relatively cumbersome, time-consuming and laborious, and the installation and positioning between plates is not accurate enough.
The rock wool sandwich board includes two layers of color steel plates and a rock wool board between the two layers of color steel plates. One side of the rock wool board is provided with a connecting plate, the thickness of the connecting plate is less than the thickness of the rock wool board, the other side of the rock wool board is provided with a groove corresponding to the connecting plate, and one side of the color steel plate is provided with a connecting piece.
Rock wool sandwich panel has the functions of sound absorption, noise reduction and heat insulation. At the same time, it has low water absorption rate, no deformation when heated, good moisture resistance, no asbestos, no fluorine, no feeding pests, no mold. It can play a role in insect and insect prevention, and is suitable for building materials.
