摘要： PROBLEM TO BE SOLVED: To form an economical protrusion, appropriate to a frictional force between ground and a columnar body, on a surface of a prefabricated pile penetrating the columnar body of soil cement. SOLUTION: A ratio between a space (s) between the protrusions of the friction pile, where the linear protrusions are provided on the surface of the prefabricated pile, and its height (h) is set at a predetermined value or below. The predetermined value is determined so that relative displacement between the prefabricated pile and the soil cement in the action of a vertical load on the friction load can be set at not more than a value obtained by subtracting the relative displacement between the soil cement and the ground from an allowance of displacement of a whole including the columnar body.

摘要： PROBLEM TO BE SOLVED: To considerably improve connecting work efficiency and to safely connect a reinforcement and an iron plate or the like at a low cost with little dispersion in connecting quality even without special skill. SOLUTION: One end of a deformed reinforcement 2 is compressed by pressing with a press or the like to form a plate-like part 1 having an almost circular plate-like part 14, and a bolt hole 11 is formed in the plate-like part with a drill or the like. The deformed reinforcement 2 and the iron plate 3 or the like which is a steel frame member, are connected by inserting a bolt 4 in the bolt hole 11 formed in the deformed reinforcement and a hole 31 formed in the iron plate or the like and tightening it with a nut 5. In the construction field, since the deformed reinforcement 2 and the iron plate 3 or the like which is the steel member, have only to be connected by the bolt 4 and nut 5, rapid and safe connection can be attained at a low cost with little dispersion in connecting quality even without skill.

摘要： PROBLEM TO BE SOLVED: To considerably improve connecting work efficiency and to attain safe connection to an iron pipe or the like at a low cost with little dispersion in connecting quality even without special skill. SOLUTION: One end of the iron pipe 1 allowing the insertion of a deformed reinforcement 2 is compressed by pressing to form a plate-like part 11, and a bolt hole 12 is opened in the plate-like part. The other end 13 of the iron pipe 1 is pressure-fitted to allow bamboo joints 21 of the deformed reinforcement 2 to bite into by pressing the outer periphery 13a to reduce the diameter by a press or the like. A bolt 4 is inserted in the bolt hole 12 of the plate-like part 11 and a bolt hole 31 opened in an iron plate 3 which is a steel member of reinforced concrete, and tightened with a nut 5. In the construction field, since the deformed reinforcement 2 and the iron plate 3 which is the steel frame member have only to be connected by the bolt 4 and nut 5, rapid and safe low-cost connection can be attained with little dispersion in the connecting quality even without special skill.
