The wall system can be divided into an outer wall system and an inner wall system according to the building parts. The exterior wall system is mostly a combined wall body, and comprises an exterior wall external heat insulation system, an exterior wall internal heat insulation system, a curtain wall, a traditional light wall body and the like.
