PURPOSE:To prevent the coming-off of a pile from its footing by a method in which the main iron bar or PC steel material of a concete pile is threaded, and an anchor plate is fixed to the main iron bar or PC steel mateial with nuts. CONSTITUTION:The tip end portion of the main iron bar of PC steel material of a concrete pile 1 is subjected to a threading process, and an anchor plate 4 is fixed to the main iron bar or PC steel material 2 by means of nuts 2. Even when a drawing force is applied to the concrete pile 1, the coming-off of the concrete pile from its footing can be prevented because the main iron bar or PC steel material 2 shares the pulling force equally. |
