PURPOSE: A holder type pile head reinforcing apparatus is provided to improve the construction ability of a holding type pile head reinforcement structure by a holding unit supporting the holder type pile head reinforcing structure on a pile head. CONSTITUTION: A holder type pile head reinforcing apparatus(100) includes an end plate(110), a vertical connection steel reinforcement(120) and a holding unit(130). The end plate is formed with a shape corresponding to the inner shape of a pile(200) and installed inside the pile at a fixed depth to block the inside of the pile at the fixed depth. The vertical connection steel reinforcements are installed vertically to the upper part of the end plate and arranged with a constant surface from each other. The holding unit bends the parts of the upper parts of two to five vertical connection steel reinforcements within the vertical connection steel reinforcements towards the outside that is placed on the pile heads.
