摘要： PROBLEM TO BE SOLVED: To improve the aseismatic property by fitting a steel cap body provided with a sliding shoe member to a pile head. SOLUTION: A steel cap body 9 provided with a flange and a reinforcing plate 15 with a cross-shaped section in the inside is fitted to a pile 1 through a filler 5 irespective of cutting of the concrete pile 1, for instance. And a rubber sliding shoe 18 is fixed to the top. Then, a steel cap body 10 is put on the top of the pile 1 through a buffering material 11 for the peripheral face and stud dowel rods 12 of a footing 13 are welded to the top face. The pile 1 head can easily move horizontally owing to the buffering material 11 and the pile 1 head can be easily restored by the sliding shoe 18. Even when the pile 1 head is shifted, a shearing force or a bending moment is not transmitted to the footing 13. A steel sliding shoe may be used instead of this and also a steel double cylindrical body having a specified structure may be fitted to the pile top cut at the head to shape a concrete form and may be used for both reinforcement and footing. In this way, the aseismatic property can be improved.

摘要： PROBLEM TO BE SOLVED: To reinforce the head section of a concrete pile cut and used. SOLUTION: A concrete pile 1 is cut in conformity with use conditions and joined integrally with the footing 13 in the structure of the concrete-pile head section. A double cylindrical body 3 unified through the annular plate of a head section and made of steel is fitted to the head section of the concrete pile 1 besides leaving in specified length of a PC steel bar 2 in a removed section at that time, an opening between the concrete pile 1 and the cylindrical body 3 positioned outside the concrete pile 1 is filled with fillers 5, and a bowl- shaped body 4 is joined at the lower end of the cylindrical body 3 positioned on the inside and concrete-stop forms are formed.
