摘要： PURPOSE: To obtain a connection structure which requires only a small space and which can be easily constructed, by fixing a steel pipe provided with external protrusions to the head of a foundation pile and fitting a large diameter steel pipe provided with internal protrusions on the above pipe and placing concrete in the inside to unify them. CONSTITUTION: A steel pipe 2 provided with protrusions 4 at the external face is fixed to the head of a foundation pile made of a driving steel pipe pile, a soil cement composite steel pipe pile, a cast-in-place steel pipe concrete pile, etc. and a large diameter steel pipe 1 provided with protrusions 4 at the internal face is fitted. The protrusions 4 are formed as spirals or intermittent stripes to place concrete without voids and unify them more securely. Concrete 3 is placed in the inside of steel pipes 1, 2 to connect together and a footing or a column base is connected through the steel pipe 1. This structure dispenses with auxiliary metal fittings for connection of a foundation slab or a steel cage or the like. In this way, a connection structure which is easily constructed can be obtained.

摘要： PURPOSE: To enhance joint strength by disposing a column leg in a steel pipe pile and casting fiber reinforced concrete in the steel pipe pile to connect the steel pipe pile and the column leg. CONSTITUTION: A steel pipe pile 1 with a protrusion is driven into the ground. Next, ordinary concrete 3 is cast into the pile 1 and cured. And a column leg 2 is inserted into the pile 1. Further, fiber reinforced concrete is placed between the pile 1 and the leg 2 and cured. As a result, since the pile 1 is connected with the leg 2 by casting the fiber reinforced concrete, sufficient shearing strength can be provided in the joining between the pile 1 and leg 2 without using reinforcing bars, as required in a conventional method. And an arranging work of reinforcing bars is not required and a column can be easily inserted and set, and hence joining between pile and column foundation can be achieved at high efficiency.

摘要： PROBLEM TO BE SOLVED: To erect a post without fixing the leg part there of an anchor bolt by applying the constitution that a plurality of positioning devices with gauge materials slidable on a seating are mounted on a steel pipe pile head, and the post suspended within the pile is adjusted to suit a position contact with the positionally adjusted and fixed gauge materials. SOLUTION: Two to four pieces of a horizontal positioning device having a seating 1 and a gauge material 2 slidable mounted thereon, are arranged on a head part of a steel pipe pile erected on foundation concrete. Then, the erection position of a post such as a steel pipe post is measured and the gauge material 2 is made to slide on the seating 1 so that the forward end position of the gauge material 2 is aligned with the external surface of the post at the measured erection position. The gauge material 2 is thereby positioned and fixed to the top plate 3 of the seating 1. Thereafter, the post is suspended and inserted within the steel pipe pile and after the post is positionally adjusted and held so as to come into contact with the guide material 2, and fixture such as a wedge is inserted in a gap between the post and the steel pipe pile. The post is thereby fixed and then concrete is placed.

摘要： PROBLEM TO BE SOLVED: To temporarily fix a post within a steel pipe pile via the wedge action of male and female camber materials even in a small gap by applying the constitution that a temporary fixing device with the male camber material fitted into space between the thick plates of the female camber material having a rod material welded between the thick plates, is inserted in a gap between the internal surface of a steel pipe pile and the external surface of a post, and then the male camber material is hammered. SOLUTION: A female camber material 4 of a temporary fixing device has a rod material welded at the prescribed angle between two rectangular thick plates, and a guide pipe 3 is welded to the external surface of each thick plate. Furthermore, a male camber material 5 made of a square rod material of trapezoidal form or the like is fitted into and inserted into space between the thick plates of the female camber material 4. Then, a guide rod 7 is passed through the guide pipe 3. Also, the temporary fixing device is locked with stoppers 8 at the upper and lower positions of the guide rod 7, and inserted in a gap between a pile and a post in the steel pipe pile by use of the guide rod 7, thereby installing the temporary fixing device at the prescribed position in a gap between the steel pipe pile and the post. Thereafter, the upper surface of the male camber material 5 is driven with a hammer or the like, thereby fastening the post within the steel pipe pile via the wedge action of the male camber material 5 and the female camber material 4.
