摘要： PURPOSE:To obtain concrete-filled steel pipe structure, in which sufficient bearing force in a connecting section is acquired by simple structure and which is excellent even in the face of workability and cost, is superior in bearing force as a framework material and has high reliability. CONSTITUTION:The end sections of a hollow internal cylindrical pipe 2 as panel points are inserted into upper and lower hollow external cylindrical pipes 1 as a post in specified length, the inside is filled with concrete 3, and the hollow external cylindrical pipes 1 and the hollow internal cylindrical pipe 2 are connected. Diaphragms 4 and beam connecting sections 5 having H-shaped cross sections are installed previously to the intermediate section of the hollow internal cylindrical pipe 2, and beams 6 are joined by bolts 8 by using splice plates 7. Projections are formed to the external surface of the hollow internal cylindrical pipe 2 by welding and studding stud dowels, and the external surface of the pipe 2 is unified with concrete 3. When unboned treatment is carried out among the internal surfaces of the hollow external cylindrical pipes 1 and concrete 3, the partial buckling of the hollow external cylindrical pipes 1 can be prevented.

摘要： PURPOSE:To use a continuous wall as a part of a round underground type structure by a method in which a continuous wall inserted with a core material is constructed, the ground inside the continuous wall is excavated, and concrete for side wall is placed into ring beams set during the excavation. CONSTITUTION:Dowel reinforcing bars 7 are welded to H-steels 2 in advance, and the ground is excavated along a guide ring 4 and the soil is replaced by cement mortar. The H-steels 2 are inserted into the cement mortar to form a continuous wall 1. The ground is then excavated to a given depth while setting ring beams 3 inside, and the dowel reinforcing bars 7 are exposed in order by chipping. Circumferential reinforcing bars 9 and vertical reinforcing bars 10 are then set, and concrete 8 for side wall is placed while embracing the ring beams 3 and the dowel reinforcing bars 7. The sheathing continuous wall can thus be utilized as a part of the base structure, and the thickness of the side wall concrete can be greatly reduced.

摘要： PROBLEM TO BE SOLVED: To provide a high-quality and economical joining structure mounted on the joining part between an upper structure and a steel pipe pile used in a severely corrosive environment. SOLUTION: The pile head part of the steel pipe pile B, adjacent to the joining part between the pile B and the upper structure C, is joined through the medium of a highly corrosion-resistant joining steel pipe 4 to the upper structure C in the severely corrosive area of steel members used for port, river and offshore structures in a splash zone, an intertidal zone 2 and the like. Consequently, it is possible to obtain an anti-corrosive method uninfluenced by the execution error of the pile B and a joining method for facilitating the execution of the pile B and the upper structure C.
