PURPOSE: To suppress the enlargement of a foundation structure and an increase in reinforcement quantity by reducing the bending bearing force without reducing the axial bearing force and shearing bearing force of a pile head part. ;CONSTITUTION: A plurality of sets of two-in-a-set diagonal reinforcements crossed in X-shape in side view, parallel to each other in plane view, and situated on both sides of a pile center are arranged in a twisted hand drum form to form an X-shaped main reinforcement group 10. Ring-like end part constraining members 11, 12 for constraining the upper and lower end parts of each diagonal reinforcement are arranged on the upper and lower parts of the X-shaped main reinforcement group. Ring-like middle part constraining members 13a, 13b for constraining the crossing position of each diagonal reinforcement are arranged in the vertical middle position of each diagonal reinforcement. Further, the upper side of the X-shaped main reinforcement group is fixed to the concrete foundation part 3 of a structure, and the lower part side of the X-shaped main reinforcement group is connected to the pile reinforcement of a pile body 1a.;COPYRIGHT: (C)1995,JPO
