いる。"Prior Art" Conventionally, for concrete filling steel pipes used, for example, as columns or piles, in order to improve the adhesion between the concrete and the steel pipes, for example, it is disclosed in Japanese Utility Model Publication No. 61-45506. As described above, the horizontal diaphragm, shear connector, vertical diaphragm, ring, etc. are welded to the inner surface of the steel pipe.

With the T-shaped steel flange and the web, it is possible to prevent circumferential deviation between the filled concrete and the steel pipe, and
In particular, a large number of projections orthogonal to the longitudinal direction of the flange surface and / or the web surface of the T-shaped steel can prevent the longitudinal deviation between the concrete and the steel pipe.

A plurality of T-section steels 2 having the above are integrally provided on the web 2c by automatic fillet welding.
前記突起2bは、ウエブ2c面に形成してもよい。The protrusion 2b may be formed on the surface of the web 2c.

容易である。"Effect of device" According to the concrete filling steel pipe used as the pillar or the pile according to the present invention described above, the rigidity of the steel pipe itself is
The flange and the web, which can be increased by the T-section steel and have the projections of the T-section steel, not only prevent the circumferential displacement between the filled concrete and the steel pipe, but also particularly the flange surface of the T-section steel. And / or a large number of projections orthogonal to the longitudinal direction of the web surface completely prevent the longitudinal displacement between the concrete and the steel pipe, so that the steel pipe and the concrete are integrated to form a composite section with strong torsion resistance. Further, since only the T-shaped steel with protrusions needs to be welded in the longitudinal direction of the inner surface of the steel pipe, the production is extremely easy.
