それがあり、これを防止すべく種々の接合部構造
が提案されている。 As is well known, when constructing a steel structure by joining steel pipe columns and beams, a large bending moment, etc. acts on the joints (joint parts) between the columns and beams, so local bending of the pipe walls may occur. There is a risk that the deformation becomes excessive and the column collapses before the strength of the column or joint is reached, and various joint structures have been proposed to prevent this.

The one described in JP-A-36524 is known. In this conventional method, a cylindrical body is provided at the upper end of the column, the beams of the cylindrical body are joined, and the wall thickness of this cylindrical body is made thicker than the wall thickness of the column to improve the strength of the joint. There is.
しかし、この従来の接合用筒体は、筒体の全体

Therefore, its characteristics are that it is concentrically joined to the upper end of a steel pipe column with an outer diameter of D and a wall thickness of T, and has the same outer diameter dimension D.
In a cylindrical body to which a beam is joined to the outer peripheral surface thereof, a plurality of stiffener rings are provided protruding in the axial direction on the inner surface of the cylindrical body, and the stiffener rings are provided at positions corresponding to the upper and lower surfaces of the joint beam, The inner diameter of the stiffener ring is d, the axial outer distance between adjacent stiffener rings in the axial direction is H,
If the thickness of the cylinder between adjacent stiffener rings in the axial direction is t, and the height of the joint beam is h, then D-2t>d≧D/2, 2D≧H≧D, H≧h, t

の場合、この上部の柱５は接合されない。 In Figures 1 and 2, 1 is a steel pipe column with a circular cross section, a cylinder 2 is concentrically welded to the upper end of the column 1, and a beam 3 made of H-beam steel is connected to the outer peripheral surface of the cylinder 2. The joint portion 4 is constructed by the following steps. A steel pipe column 5 is further joined to the upper end of the cylindrical body 2, but in the case of the top floor, this upper column 5 is not joined.
上記筒体２の上の上下端部の内面には、スチフ
ナ（補強）リング６，６が突設されている。 Stiffener (reinforcement) rings 6, 6 are provided protruding from the inner surface of the upper and lower ends of the cylindrical body 2.

とを意味している。 D>2t>d≧D/2 ... 2D≧H≧D ... t>T ... H≧h ... In other words, the above formula specifies the inner diameter dimension d of the stiffener ring 6. If the inner diameter dimension d is less than 1/2 of the outer diameter D, it becomes difficult to fill with concrete, so it is set to d≧D/2. In particular, since concrete is not only filled from the top of the column but also pumped up from the bottom of the column, the internal cross-section of the cylinder is set to at least 1/4 of the column cross-section. Further, D-2t>d means that the ring protrudes inward, and this means that the stiffener ring 6 portion is thickest and strong in terms of strength.

Since h>D is set, if the upper and lower stiffener rings 6, 6 are provided in the relationship of the above formula, the flanges 7, 7 on the upper and lower sides of the beam 3 can be made to correspond approximately to the positions of the stiffener rings 6, 6. It is. Also,
If D>H, it is considered a light beam and does not require reinforcement, and if 2D<H, it is excluded from the scope because it requires special design as a structural type.
また式は、筒体壁部が筒体２に作用する剪断
