1を取り巻いて穿設されている。The steel pipe 1 forms the core of the joining member 10, and the cross-sectional shape of the steel pipe may be circular or rectangular. In this embodiment, the steel pipe 1 has a rectangular cross section, and the steel pipe has an upper end and a lower end. The fixing plate 2 is welded to the. Then, the steel pipe outer diameter region 2a of the fixing plate 2,
That is, in a region where the fixing plate 2 protrudes outside the diameter of the steel pipe 1, a proper number of through holes 20 through which the column main bars 40 are inserted are formed around the steel pipe 1.

設用の開口7が設けてない点で、従来と大きく異なる。In the joining member 10 constructed as described above, the connection with the reinforced concrete columns 4 is performed by fixing the screw ends of the main bars 40 of the reinforced concrete columns 4 to the fixing plate 2 in each of the upper and lower fixing plates 2. The fixing plate 2 is inserted through the through hole 20 from the outside, and the upper and lower surfaces of the fixing plate 2 are tightened by two nuts 6 screwed to the threaded ends of the fixing plate 2 to be fastened and coupled to each other. At this time, it is better to tighten the nut 6 on the joining member side. Further, the main bar 40 may be divided in the joining member 10 or may be continuous. In any case, steel pipe 1
The main rebars 40 of the reinforced concrete columns 4 are inserted outside and fixed with screws, and the fixing plate 2 is not provided with the opening 7 for placing concrete, which is a big difference from the conventional one.

れる。The joint portion constructed as described above is different from the conventional one in that it is made of only a steel frame material (steel pipe 1, fixing plate 2, joint plate 3). The stress transmission mechanism from the steel beam 5 to the joint is "through diaphragm type" in pure steel construction.
The stress transmission mechanism from the joint to the reinforced concrete column 4 is the same as that of the exposed column base made of pure steel. Therefore, it is considered that the design of this joint can be performed according to these.

る。In the stress transmission between the joint portion and the reinforced concrete column 4, when the friction force between the fixing plate 2 and the reinforced concrete column 4 is expected to be designed, when the friction force is insufficient, a checker is attached to the fixing plate. It is sufficient to use a plate in the shape of a circle. Further, the column main bar 40 and the fixing plate 2 are fastened and coupled by sandwiching the fixing plate 2 from both upper and lower sides with two nuts 6 and 6 screwed to the screw ends of the column main bar 40. It is possible to surely transmit stress to the main bar 40 in the upper and lower directions.
Therefore, the strength against vertical vibration can be improved as much as possible.

クリートの合成構造として設計することも可能である。In consideration of the concrete pouring of the reinforced concrete columns 4, it may be convenient that the fixing plate 2 has an opening. However, in the present joining method, a circular shape is formed according to the stress of the steel beam 5. Alternatively, a rectangular opening 7 can be provided. In this case, the joint can also be designed as a composite structure of steel pipe and unreinforced concrete.

This joining method can be applied to any half-precast, full-precast or cast-in-place reinforced concrete columns. Here, the nut 6 on the concrete column 4 side may be embedded in advance, or the end face around the main bar 4 may be attached to the nut 6 at the time of construction. Alternatively, first, the concrete pillar 4 may be attached to the screw end portion of the main bar 40 protruding from the end surface of the concrete pillar 4.
Side nut 6 is screwed and abutted against the end face, and in this state, the main bar 40 is inserted into the through hole 20 of the joining member 10 and the nut of the fixing plate 2 side is screwed and fastened and coupled to each other. The grout may be injected into the gap formed between the subsequent fixing plate 2 and the end face of the concrete column 4 by covering the periphery thereof with a mold or the like.

Therefore, compared to the conventional structure in which the steel frame and the reinforcing bar are intricate,
The workability of the steel frame will be good, and the workability of placing concrete will also be good. Further, the column main bar and the fixing plate are fastened and coupled by sandwiching the fixing plate from both upper and lower sides with two nuts screwed to the screw portion of the column main bar. It is possible to reliably transmit the stress.
