The sandwich heat insulation of the outer wall is a durable energy-saving wall which can integrate bearing, heat insulation (sound insulation) and decoration and is suitable for different areas, and is a heat insulation technology which can solve the problem that the service life of a heat insulation layer is the same as that of a building. However, the sandwich wall has the defects that only the middle layer with soft texture can be filled in the sandwich wall, so that the inner wall body and the outer wall body are weak in support and cannot bear large impact and impact, and the outer wall body is easy to damage; meanwhile, even if the structure of the outer wall body is kept intact, the deformation of the outer wall body can cause certain damage to the middle layer, and the heat preservation and noise reduction capabilities are reduced. Therefore, further improvements are awaited.
