Abstract

PURPOSE:To directly connect a base column to the top of a pile by a method in which anchor bolts are set in the top of a pile, and the base column is connected to the upper end of a large-diameter pile by the bolts to form a footing integrated with the top of the pile. CONSTITUTION:Concrete 14 is placed into the top 11 of a large-diameter PC pile 1 penetrated into the ground and anchor bolts 15 are set. A concrete or reinforced concrete footing 5 is formed integrally with the top of the pile on the periphery of the pile top 11. A column is set through a level-regulating liner 16 on the top of the pile and fixed by the bolts 15. The anchor bolts can thus be easily set, and setting of the column and the other operation can be concurrently performed.

"Effects of the Invention" According to the present invention, it is possible to directly connect the frame column to the pile head, and to form a footing that is integral with the pile head, so that the pile head is reinforced. This eliminates the need for intermediate digging and reinforcing bars. Additionally, anchor bolts can be installed easily, and pillar erection and other work can be done at the same time, reducing construction time. Furthermore, since the top of the stake can be located above the ground level, the positional flexibility of the top of the stake can be improved.
