According to the present invention, a construction method for connecting new concrete and old concrete includes a step of screwing and coupling a bar coupler to a reinforcing bar buried in concrete when the concrete is poured; a step of screwing and coupling a fixing cap screw to the bar coupler through a coupling hole of the joint steel plate from a side opposite to the joint steel plate to which the bar coupler is coupled in order to fix the bar coupler to the joint steel plate; a step of forming a primary concrete structure by pouring concrete so that the reinforcing bar is buried; a step of screwing and coupling, to the bar coupler, the joint bar buried in a slab connected to the primary concrete structure after removing the fixing cap screw from the bar coupler; and a step of forming a slab by pouring concrete so that the joint bar is buried in order to form a slab connected to the primary concrete structure. |
