In the prefabricated sandwich heat insulation wall construction process, the prefabricated sandwich heat insulation wall needs to be assembled and connected with the structural column of the building. The connection of the prefabricated sandwich heat insulation wall and the structural column surface is very important, and good processing can effectively prevent heat loss and temperature fluctuation and maintain the stability of indoor temperature.
