As described above, according to the Takahashi pier of the present invention, since the leg is a so-called filling type steel pipe concrete structure composed of concrete and steel pipe, the axial force is applied to the concrete and the bending is applied to the steel pipe. The strength of both materials can be utilized, the weaknesses can be complemented and the rigidity and toughness can be enhanced, and the amount of reinforcing steel can be reduced or the wall thickness of the steel pipe can be reduced compared to the conventional one. Economic efficiency can be improved. In addition, the concrete made of superfluid concrete is filled into every corner of the leg steel frame without compaction work, and the concrete and the steel pipe are firmly joined through the ribs on the inner surface of the steel pipe. The strength is increased, the leg can be made highly rigid and tough, and the degree of freedom in design can be increased. Furthermore, since there is no seam in the concrete, no seam treatment is required and the concrete can be made homogeneous. On the other hand, according to the Takahashi pier construction method,
After the construction of footing , the work at the site was carried out with the beam form and leg steel frame.
Fine leg steel frame between the assembly, as well as only become pouring of concrete, the number of steps and Engineering species than the conventional can be reduced greatly, and to narrow the work yard to minimize the destruction of the environment You can In addition, concrete pouring is a beam
Since it carried out once the mold and leg steel frame and after assembly between the legs steel frame, it is possible to significantly reduce yield, and the construction period to homogenize the structure. Furthermore, the assembly between the beam-type frame and leg steel frame and legs steel frame, since carried out at a relatively low single scaffold near the ground, it is possible to increase the safety of operations, the amount of scaffold It can be drastically reduced.
