The structure of the Seamless Insulation Core Decoration Integrated System (finished decorative board structure with pouring insulation core) makes full use of new energy obtained from building exterior walls. Large boards can use photovoltaic panels, and special-shaped boards use finished decorative boards. Its value innovation perfectly realizes resource conservation and comprehensive utilization of sunlit wall resources. The structure features layered board bearing ventilation and drainage and track structure for installing external wall decorative panels. Its value innovation manages the insulation and decoration system by discharging wall moisture, eliminates the risk of uneven technical worker skills and the problem of indoor wall moisture and wallpaper mildew during the annual plum rain season, cancels external wall embedded parts and dry-hanging keels, external wall silicone waterproofing, external wall insulation scraping of anti-cracking mortar with mesh cloth, and external wall scraping of putty for leveling. The value innovation of poured-type filling seamless insulation enhancement technology improves the safety standards and installation efficiency of building energy-saving decoration. The perfect realization of the control technology for the tensile strength of the wall insulation core is through the seamless insulation structure formed by each L-shaped aluminum alloy connector of the layered board bearing ventilation and drainage aluminum alloy structure system. The new wall omits the plasterer leveling process. For old building renovation, there is no need to remove the original hollow and cracked insulation layer, ceramic tile finish, or paint finish, eliminating the generation of insulation board solid waste. Figuratively speaking, the decorative panel of the Seamless Insulation Core Decoration Integrated System (finished decorative board structure) is like a template, the L-shaped aluminum alloy connector is like steel bar, and LOULIWAI9598 and 9599 aerated concrete insulation pouring materials are like concrete. It has uniquely created a different concept of carbon reduction and pollution reduction in the insulation and decoration industry, and this characteristic of the system will play an immeasurable role in benefiting humanity. If this system is widely applied in large national grain reserves, food reserves, power grid machine rooms and distribution rooms, hospitals, colleges, hotels, office buildings, and old residential buildings in China, it will have a revolutionary impact.
