0 will be described with reference to FIG. To install the press-fitting jig 20, as shown in FIG.
2 and the connecting plate 34 of the adapter 30 are overlapped and inserted between the angle members 14, and are integrally fixed to the steel pipe column 10 by bolts 25 a, 25 b, 25 c (FIG. 5A). At this time, the injection hole 12 of the steel pipe column 10 is in an open state. Prior to mounting the press-fitting jig 20, it is desirable to apply grease to the back surface (the contact surface with the steel pipe column 10) of the partition plate 22.

Since grease is applied to the back surface of the partition plate 22,
Slide smoothly. Further, the partition plate 22 is made of the steel pipe column 1.
Since it is in close contact with zero and there is almost no gap, concrete does not spill outside. The partition plate 22 is the injection hole 1
At the position where 2 is closed, the bolt 25a is tightened again to fix the partition plate 22 (FIG. 5B).

に、信頼性が高い。According to the first aspect of the present invention, since the press-fitting jig can be diverted, the amount of steel material can be significantly reduced. In particular, since the partition plate forming a part of the press-fitting jig is directly welded to the steel pipe column as a reinforcing plate, the working process is extremely simple. Also, the welding work of the reinforcing plate,
Since it is performed from the outside of the steel pipe column, workability is excellent and reliability is high.
