``Prior art'' As is well known, a filled steel pipe concrete column is constructed by filling a steel pipe with concrete.Of the forces that are applied, the axial force (vertical force) is borne by the concrete, and the bending force etc. are borne by the concrete. This allows the steel pipes to share the force commensurate with the proof strength of each structural member, which has the effect of reducing the cross section of the column.

The pillar 1 is composed of a steel pipe 3 and concrete 4 filled therein. The scrap pipe 3 is composed of a joint steel pipe 3a to which the steel beam 2 is connected, and a shaft steel pipe 3b located above and below the joint steel pipe 3a. A ring-shaped bearing plate 5 is protruded from the inner and outer peripheral surfaces or the inner peripheral surface of the joint steel pipe 3a, and the vertical force of the steel beam 2 is transmitted to the concrete 4 via the bearing plate 5. It has become so.

- Since the steel beam 2 is joined to the steel pipe 3, the vertical force of the steel beam 2 is also applied to the steel pipe 3, and the strength of the steel pipe 3 decreases at the joint.

- Since the bearing plate 5 protrudes inside the steel pipe 3, the filling efficiency of the concrete 4 may be reduced and the concrete 4 may not be filled uniformly, in which case the yield strength of the concrete will be reduced.

■In order to avoid the problems described in ■ above, when pouring concrete 4, it is necessary to temporarily stop the concrete at the bottom of the bearing plate 5 and wait for the concrete to harden before pouring again. This requires time and effort.

(2) As mentioned above, since the protruding dimension of the bearing pressure plate 5 is kept small in order to prevent the filling efficiency of the concrete 4 from decreasing as much as possible, the bonding area between the bearing pressure plate 5 and the concrete 4 is small. Therefore, the bonding force between the steel beam 2 and the concrete 4 is weak, and the vertical force applied to the steel beam 2 cannot be sufficiently transmitted to the concrete 4.
