Joint structure between cft column and pier reinforcement cage

According as the present invention is bonded to a concrete filled steel tube column (Concrete Filled Steel Tubular Column) and peer reinforcement mesh (based reinforcement mesh) (Pier Reinforcement Cage) coupled to a lower end thereof, CFT pillar in the peer to axial load of the structure as efficiently concrete filled steel tube column having a novel structure to be able to deliver the peer relates to bonding of the reinforcing network syntax. That make up the axial loads acting on the concrete filled steel tube column the column pipe, is passed to the peer through the interior of the concrete and reinforcement, according to the present invention, the peer to load steel pipe is covered by the axial load applied to the concrete filled steel tube column rebar to be passed directly to the network, the structure of the peer and the concrete filled steel tube column bond the reinforcement mesh integrally with the coupler is provided. Concrete filled steel tube column as peer-junction structure of the reinforcing net according to the present invention, the tower can be applied to the basement construction of buildings according to the download method. CFT, concrete filled steel tube, top-down, a peer network reinforcement columns, joining
