However, since such a joint structure requires on-site welding, not only is a specialist required, but quality control is not easy, costs are increased, and the construction period is prolonged. In addition, there is a thing which bolts a beam to the capital of a column with a split tee, etc., but in that case, a length part for bolt connection is necessary above the beam on the side of the column, and from the beam top to the top of the column capital Long distance is required. For this reason, the payment is poor.

での距離が短くて納まりが良い。According to the present invention, there is provided a column-beam-no-weld joint structure for a column head, in which angle members are bolted to four side surfaces on the inner surface of the upper end of a rectangular steel tube column, respectively, and are disposed on the upper surface of the rectangular steel tube column. A horizontal top plate having a beam connecting piece extending in a plurality of directions is bolted to each of the angle members, and an upper flange at an end of the beam made of H-section steel is bolted to a beam connecting piece of the top plate. Is connected to the peripheral wall of the rectangular steel pipe column via an end plate provided on the beam or a split tee bolted to a lower flange of the beam. According to this configuration, all the joints with the beams at the column heads of the rectangular steel tube columns can be performed by bolt joints. Therefore, the quality is stable, the cost can be reduced,
The construction period can also be shortened. In addition, since the upper flange is bolted to the top plate of the capital, the distance from the beam top to the upper end surface of the capital is short and fits well.

In the case of this configuration, even if the bolt insertion hole is formed in the square steel pipe column, sufficient strength can be provided by compensating for the cross-sectional loss due to the bolt insertion hole. In addition, since the thick-walled portion is obtained by increasing the thickness of a steel pipe by heating and compression, the material cost can be reduced as compared with the case of using a cast iron pipe or the like. The thick part,
Only the lower half of the beam joint height range at the column head of the rectangular steel tubular column may be used. The upper end of the rectangular steel tube column, that is, the portion corresponding to the upper flange of the beam can obtain the stiffening effect by the top plate, but the portion corresponding to the lower flange of the beam cannot obtain such a stiffening effect. The strength is secured in the meat part. By reducing the thick part in this way,
It is possible to make the rectangular steel tube column lean against the required strength,
Cost can be reduced.

なる。Instead of providing the thick portion, an internal reinforcing plate is overlapped on at least four beam joining height ranges on the four side surfaces of the column head of the rectangular steel tubular column, and the angle member is bolted to the inner surface of the internal reinforcing plate. Further, the bolt connection between the end plate or the split tee and the rectangular steel pipe column may be performed by a bolt penetrating the internal reinforcing plate. In the case of this configuration, the bolt joint portion of the square steel tubular column can have sufficient strength with a simple configuration without performing a wall-thickening process by heating or compression. In addition, the internal reinforcement plate which overlaps with the four side surfaces of the square steel pipe column may be only the lower half of the beam connection height range of the square steel pipe column. In each of the above configurations, an opening may be provided substantially at the center of the top plate. In the case of this configuration, a normal high-strength bolt is used by manually inserting a bolt from the opening to the bolt connection between the top plate and the angle member and the bolt connection between the peripheral wall of the square steel tubular column and the lower part of the beam end. Cost can be reduced. In each of the above configurations, the top plate may be unopened, and the bolt that joins the end plate or the split tee to the rectangular steel pipe column may be a one-side bolt. In the case of this configuration, all bolt joining operations can be performed only from the outside without inserting a hand into the square steel pipe column, and the operation is simplified.
