摘要： PROBLEM TO BE SOLVED: To provide a cast-in-place steel pipe reinforced concrete pile which can ensure stress transfer between a steel pipe and reinforced concrete by preventing slip between the steel pipe and the concrete, which can be manufactured by virtue of a high degree of design freedom, which does not deteriorate the infilling of the concrete in the placing of the concrete, and which can restrain hole wall slurry from affecting a force of adhesion between the concrete and the steel pipe. SOLUTION: An upper section 10 of the pile comprises: the vertically elongated steel pipe 11 with a smooth inner surface; a plurality of anchor bars 12 which are fixed to the upper outer peripheral surface or inner peripheral surface of the steel pipe by welding or a bolt etc. and elongated into a footing 1 of reinforced concrete construction; a plurality of first annular ribs 13 with a chevron-shaped cross section, which are formed on the inner surface of the lower end of the steel pipe at axial intervals; a plurality of first pile main reinforcements 14 which are provided inside the first annular ribs in such a manner as to be elongated to the lower end of the steel pile from a lower section of the pipe; a plurality of first hoop reinforcements 15 which enclose the first pile main reinforcements in such a manner as to be orthogonal to the first pile main reinforcements; and the concrete 16 which is continuously infilled into the steel pipe from an upper end to a lower end.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a steel tube with a projection where pathces are made to follow the strain of a steel tube and the ruggedness of the surface in the steel tube, thus a gap between each patch and the steel tube can be fixedly held so as to be narrow, and also, friction resistance generated between each patch and the steel tube can be low suppressed, and further, which can widely cope with the difference in steel tube sizes with a reduced kind of patches, and to provide a device therefor.
SOLUTION: The manufacturing method for a steel tube with a projection includes: a stage where a pair of patches 2, 2 are set on the inner face of a steel tube 1 at intervals; a stage where the patches 2, 2 are pressed against the inner face of the steel tube 1 by pressing means 30, 32, so as to be brought into contact therewith; and a stage where, as the contact pressure of the patches 2, 2 to the steel tube 1 is controlled to a prescribed range by the pressing means 30, 32, while relatively moving the patches 2, 2 and the inner face of the steel tube 1, a projection P is formed by welding at a prescribed position in the space between the patches 2, 2.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a steel tube with projections which can easily and economically form, on the steel tube, projections which are high compared with the width, and provide patches to be used for the manufacture of the same tube. SOLUTION: The invented manufacturing method uses the patches 2 and 2 which vary in height in the longitudinal direction, so that the welding position and welding height can be varied depending on the number of weld layers in multilayer overlaying. This prevents a welding torch 5 from interfering with the patches 2 and 2 or prevents the welding position from being unstable due to a long welding wire 6, even in the event of forming high projections so that the projections which are high against their width can be manufactured easily and economically in the best form.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a steel tube with projections, by which high projections are easily formed using overlay welding, and to provide the tube manufactured thereby.
SOLUTION: To form projections on the inner face of a steel tube 1 in a circumferential direction, first the steel tube 1 is laid on its side and a pair of patches 2, 2 are disposed on the bottom side of the inner face of the steel tube 1. Then, a boom of a welding device, which is positioned outside the steel tube 1, is inserted into the inside of the tube 1, and a welding wire 6 of a welding torch 5, which is mounted on the front end part of the boom, is inserted between the pair of patches 2, 2. Next, while rotating the steel tube 1 in the circumferential direction, an arc is generated in the space formed by the inner face of the tube 1 and the patches 2, 2 to conduct downward overlay welding.
