It is a kind of prefabricated exterior wall structural material, also known as prefabricated external wall panel. This is a very common exterior wall material. It is generally used in the construction of the main structure and is not installed until it is completed. It is used for maintenance and decoration, and is simple and convenient to install, but it cannot be used for exterior walls of load-bearing prefabricated panels.
Reinforced concrete plate-shaped components for building assembly are processed in prefabricated factories (fields) or construction sites, referred to as wall panels or siding panels. The use of prefabricated large-board buildings can improve the degree of factory-based and mechanized construction, reduce wet work on site, save on-site labor, overcome seasonal effects, and shorten the construction cycle.
The classification function of wall panels
There are three types of front exterior wall panels, gable panels and eaves panels. The front exterior wall panels are self-bearing wall panels, while the gable panels and eaves panels are load-bearing wall panels. Exterior wall panels should not only have sound insulation and fire protection functions.
It should also have the functions of heat insulation, impermeability, freeze-thaw resistance, and carbonization resistance, and meet the requirements of architectural art decoration. Exterior wall panels can be made of a single material of light aggregate or composite materials. (structural layer, thermal insulation layer and finishing layer).
