Under the situation of continuous development of the modernization of the construction industry, prefabricated exterior wall panels will gradually develop into standard prefabricated components for design, production and installation. The existing prefabricated exterior wall panels have realized the integration of structural insulation, but the integrated technology of decorative insulation structure still needs to be researched and developed.

Most of the traditional rural residential construction is a masonry structure house with sintered ordinary bricks as the main building material, and most of the houses built with clay bricks use clear water walls. Clay bricks have strong strength, thermal performance, fire resistance, and frost resistance. However, because clay materials occupy farmland, large and medium-sized cities have gradually "prohibited the use of solid clay bricks in residential construction for a limited time" in batches. At the same time, in the process of new rural construction, a large number of discarded fired clay bricks cannot be effectively reused.

Simultaneously, when the existing prefabricated wall panels are processed and manufactured, they are usually made by direct fabrication. The base of the wall is constructed first, and then the base of the wall is constructed layer by layer until the decorative surface. The decorative surface of this production method is bonded to the structural layer through a mortar layer. After the mortar layer is formed into a single flat plate, it is very easy to cause the problem that the bonding is not firm and the decorative surface falls off. At the same time, positioning is required when the decorative surface is arranged. , the production time is longer.
