成することが望ましい。Applicant uses a beam-joined cylindrical body of a cylinder field whose wall thickness is larger than the thickness of the column, welds and joins the square steel pipe columns above and below the beam-joined cylinder, and inserts it into the screw holes on the side of the beam-joined cylinder. We have developed a structure that joins the beam and the column by screwing a high-strength bolt penetrating the end plate on the end face of the steel beam into the screw hole. (See Japanese Patent Publication No. 61-58620) By the way, in steel frame, it is sometimes preferable to connect the columns at the middle of the upper and lower floors or at a place above the floor. It is desirable to form the pillars integrally.

において接合されていることを特徴とするものである。According to the present invention, a beam joint 10 composed of a flat outer peripheral surface 10a for attaching a beam 3 and a thick portion 2 bulging on the inner surface is integrally provided in a column / beam joint structure, and the thick portion 2 is formed into a tapered portion 11. The steel column 1 connected to the main body 1a is erected through the upper and lower floors, and the end plate 5
The beam is joined at the middle portion of the column by screwing a high-strength bolt 6 inserted through the screw hole 4 into the screw hole 4 formed in the thick portion 2 of the beam joining portion 10.

範囲t2の肉厚部２が形成されている。FIG. 1 is a partial longitudinal sectional view showing an example of a column / beam joint structure of the present invention, and FIG. 2 is a transverse sectional view thereof. In these figures, a square steel pipe column 1 erected through the upper and lower floors is provided integrally with a beam joint 10 in the middle thereof so as to increase the wall thickness. The beam joint 10 is a flat outer peripheral surface 10 to which the beam 3 is attached.
a and a thick portion 2 swelling on the inner surface. That Joints 10 relative to the thickness t 1 of the main body portion 1a of the angular tubular columns 1,
Thick portion 2 in the range t 2 of 2.0～4.0T 1 is formed in a range h 2 of 1.0~1.5h adult h 1 of the beam 3.

パ部11によって連続される。As shown in FIG. 1, the thick portion 2 is connected to the main body portion 1a of the square steel tubular column 1 by a tapered portion 11. That is, the change from the thickness of the thick portion 2 to the thickness of the main body portion 1a is continued by the tapered portion 11.
肉厚部２には所要数のねじ孔４が形成してあり、Ｔ形
鋼等からなる梁３のエンドプレート５の透孔を貫通した
高力ボルト６を前記ねじ孔４に螺着することにより角鋼
管柱１と梁３が接合される。A required number of screw holes 4 are formed in the thick portion 2, and a high-strength bolt 6 that passes through a through hole of an end plate 5 of a beam 3 made of T-section steel or the like is screwed into the screw hole 4. Thereby, the square steel pipe column 1 and the beam 3 are joined.

梁の接合がなされる。The present invention has the above-described structure, and has a bulged thick portion formed on an inner surface of a beam joint provided integrally with a square steel pipe column passing through upper and lower floors, and a screw hole is formed in the thick portion. By screwing a high-strength bolt inserted through the end plate of the beam into the screw hole, the column / column can be used without using a special joint.
The beam is joined.
そして梁接合部における肉厚部はテーパ部によって角
鋼管柱の本体部分と連続しているので、梁からの曲げ応
力は梁接合部からスムーズに角鋼管柱の本体部分に伝達
される。そのため本体部分と肉厚部の境界部分に曲げ応
力が集中した該部分を損傷もしくは破壊することを有効
に防止できる。Since the thick portion at the beam joint is continuous with the main body of the square steel tube column by the tapered portion, the bending stress from the beam is smoothly transmitted from the beam joint to the main body of the square steel tube column. Therefore, it is possible to effectively prevent damage or destruction of the portion where the bending stress is concentrated on the boundary portion between the main body portion and the thick portion.
またこの構造によれば接合筒体を使用しないので柱の
溶接部が少なくてよい。Further, according to this structure, since the joining cylinder is not used, the number of welding portions of the columns may be small.
