[0002] External wall insulation engineering is a building entity formed by combining, assembling, constructing or installing the external wall insulation system on the outer surface of the exterior wall. It has two significant advantages of thermal insulation and heat insulation, and is widely used in existing buildings. The traditional insulation construction method for exterior walls mostly adopts the pasting method. The process includes base treatment, preparation of adhesives, pasting of insulation boards, installation of fixings, bottom layer mortar, laying of alkali-resistant mesh cloth, surface layer mortar, insulation system acceptance and finishing layer construction. The construction process is relatively complicated. Not only is the construction period long and the cost high, but the insulation board is constructed by pasting, the structure is not strong enough, the bonding layer is not full, there are many cavities, it is easy to fall off, and its service life is relatively short. In recent years, many accidents of insulation boards falling off and injuring people have occurred, which has had a certain impact on the safety of people's lives and property. Utility Model Content
