JOINT MEMBER AND JOINT STRUCTURE FOR STEEL PIPE SHEET PILE

PROBLEM TO BE SOLVED: To provide a joint member and a joint structure for steel pipe sheet piles improving the shearing yield strength of the joint structure in comparison with a conventional joint structure while rationalizing construction by reducing the number of spaces for sediment removal and mortar injection in a set of joint members in comparison with a conventional P-P type joint member. SOLUTION: The set of joint members are mounted to the outer surfaces of steel pipe sheet pile main pipes 1 along the axial direction of the steel pipe sheet pile main pipes 1 to fit and lock the adjacent steel pipe sheet pile main pipes to each other by a male member 3 of T-shaped cross section and two female members 2 of L-shaped cross section. A flange part 3a of the male member 3 are provided with a plurality of through holes 3c. An added member 5 of plate shape is disposed at the outer surface of the steel pipe sheet pile main pipe in a space surrounded by the female members 2, and the surface of the added member 5 of plate shape is provided with a plurality of projections 6.
