PURPOSE: A connect joint for a combined file, which reduces manufacturing costs by minimizing manufacturing processes, is provided to improve work efficiency by fixing a steel pipe using a joint part. CONSTITUTION: A connect joint for a combined file comprises a first plate(110), a steel wire hole(120), a second plate(130) and a rib(140). The first plate has a hollow part on the center part and is fixed to the leading end of the concrete pile. The steel wire hole is formed at the first plate. The steel wire is buried in the steel wire hole in a longitudinal direction in a concrete pile manufacturing process. |
