In response to the new requirements for the"decoration integration"of new prefabricated buildings,a relatively mature new type of lightweight integrated envelope system that is compatible with prefabricated buildings is developed.The system takes into account good safety,thermal insulation,fire prevention,waterproofing,and sound insulation performance,achieving structural integration of insulation,decoration and functions,which fulfills factory prefabricated production,and on-site assembly installation.This article briefly introduces the design concept of the system,and conducts its standard board type and size,architectural template layout design,and main raw materials selection.In addition,the main construction nodes of the system have been optimized and designed to ensure the rationality and reliability of the selection.
