Patent KR-20210009014-A (KR)
Inventor: HAN JIN HEE
IPC: E02D9/00
Filed: 2019-07-16
Abstract: According to the present invention, in a cage consisting of a spiral reinforcing bar (130) and a steel wire (120) or a vertical PC steel bar vertically embedded in a prestressed reinforced concrete pile, protrusion-shape fixing devices (200) are coupled to the vertically embedded vertical PC steel bar or steel wire (120) at regular intervals. Then concrete is deposited in a pile mold and pretension is applied. Then the pile is cured to strengthen the attaching force between pile concrete (100) and the vertical PC steel bar or the steel wire (120) by the protrusion-shape fixing devices (200) coupled to the PC steel bar or the steel wire (120). Even if a circular fixing device (140) on an end of an existing PC steel bar or steel wire disappears by cutting the pile for finishing the head of the embedded pile, the protrusion-shape fixing devices (200) coupled to the PC steel bar or the steel wire (120) remaining after cutting the pile perform a support device function for maintaining pretension instead. According to the present invention, the pretensioned prestressed concrete pile couples a PC steel bar or a steel wire (120) embedded in a precast hollow pile (100) and protrusion-shape fixing devices (200) to prevent prestress loss when manufacturing the pile by the protrusion-shape fixing devices (200) even when cutting the pile. Therefore, the resistance strength against the vertical force and horizontal force of the pile is maintained without changes.
