Problems solved by technology

The non-load-bearing components of the masonry unit are secondary structures in the building structure. During the construction process, the quantity is large and the area is wide. It requires a large amount of labor such as masonry workers, plasterers, scaffolders, and small workers. The work intensity is relatively high and the operation cycle is long. , there is more pollution and waste, which is not conducive to the technological update and progress needs of building industrialization and green construction
Especially when the traditional building walls want to achieve the multi-functional requirements of thermal insulation and sound insulation, the method of masonry plus thermal insulation and sound insulation is generally adopted, which not only increases the cost and process time, but also has a very high space utilization rate and material loss rate
