PURPOSE: A coupling apparatus for a concrete pile is provided to simplify the construction of a pile by easily assembling a tip coupling unit and a head coupling unit using a bolt and a nut. CONSTITUTION: A coupling apparatus for a concrete pile comprises a tip member(200), a head member(300), a bolt(400), and a nut(410). The tip member comprises a tip coupling unit(220) and a guide protrusion. The tip coupling unit a tip cap(210) and a through hole. The tip cap covers the tip of a concrete pile(100). The guide protrusion is protruded along the outer edge of the tip cap. The head member comprises a head cap(310), a head coupling unit, and a guide groove. The head cap covers the head of the pile. The head coupling unit is protruded from the outer edge of the head cap and has multiple through holes. The guide groove is formed in the top end of the head coupling unit and corresponds to the guide protrusion of the tip member. The bolt is coupled to the nut to couple the tip member and the head member.
