The present invention relates to a socket integrated sleeve and an air duct construction method using the same. A technical main idea of the present invention reduces production costs and improves workability by combining a socket integrated sleeve to a construction hole of bottom concrete formed on each layer and inserting the socket integrated sleeve into a vertical standpipe as a socket shape and bonding the socket integrated sleeve with silicon and making a sleeve performs as a role of layer separation and as a connection pipe at the same time when an air duct constructed in an apartment house is combined to multiple vertical standpipes. The present invention secures durability even if the transformation of a duct pipe is generated according to the air current thermal expansion and lifespan of a building with an individual connection method between layers and improves housing safety by completely blocking damp between layers when a fire breaks out. |
