MECHANICAL CONNECTION UNIT FOR THE RC-SC CONNECTION

The present invention relates to a device for mechanically connecting RC-SC connections and, more specifically, to a device for mechanically connecting RC-SC connections in which an RC structure unit, which is composed of a steel bar and concrete wrapping around the steel bar, and an SC structure unit, which is composed of a surface steel sheet, multiple studs fixed on the surface steel sheet for the combined movement of the concrete and the steel sheet, a rib for supporting the surface steel sheet and a tie bar, are connected to each other. The present invention provides the device for mechanically connecting RC-SC connections, the device comprising: a support steel sheet vertically fixed on the surface steel sheet and maintained in a horizontal state; a connection rod having one end connected to the steel bar and the other end passing through the support steel sheet and fixed by a nut; a coupling metal piece for coupling and connecting the connection road and the steel bar; multiple reinforcing stiffeners which are arranged among the connection rods and vertically fixed on the lower surface of the support steel sheet and which have a trapezoidal shape; and a steel plate horizontally supported on the lower end of the reinforcing stiffener. The device for mechanically connecting RC-SC connections according to the present invention is provided to use the connection rod to securely connect a steel bar to the device which is composed of the support steel sheet and the reinforcing stiffeners and to secure the structural stability of the RC-SC connection by smoothly delivering load, which is generated by the steel bar of the RC structure unit, to a large steel bar over #14 which does not allow the steel bars to be overlapped for connection.
