Support column and supporting structure combined with steel tube concrete column and prestressed pipe pile and construction method

Abstract

The application discloses a kind of steel pipe concrete column and prestressed pipe pile combined support column, supporting structure and construction method.The steel pipe concrete column and prestressed pipe pile combined support column, including steel pipe concrete column, prestressed pipe pile and connecting piece.Steel pipe column in steel pipe concrete column is connected with prestressed pipe pile respectively with connecting piece, is connected into an organic whole by connecting piece, then pours concrete in steel pipe column to form steel pipe concrete column.Connecting piece adopts concrete filled steel structure, and the upper steel pipe and the lower steel pipe of two ends are inserted into steel pipe column and prestressed pipe pile hole a certain depth, reliable hinged joint can be formed, can satisfy the shear resistance and pressure requirement of column.Connecting piece is also fixed with steel pipe column and prestressed pipe pile using welding and bolt connection, provide certain shear resistance and bending carrying capacity.The application has the advantages of convenient construction, cost saving and shortening construction period.
