密着するように取り付ける必要がある。Conventionally, various joining methods have been developed and implemented as a method for joining a steel beam made of an H-section steel or the like to a steel column made of a closed section material such as a square steel pipe or a circular steel pipe,
One of the joining methods is to install a column / beam joint fitting formed in the shape of a short column with a diameter slightly smaller than the inside diameter of the steel column inside the beam joint of the steel column, and attach the steel frame to the beam / column joint. A joining method of fastening a joining bolt from the outside of a column is generally known. At this time, it is necessary to attach the column / beam joint hardware so as to be in close contact with the inside of the beam joint.
しかし、鉄骨柱の梁接合部の内側に完全に密着するよ
うな柱・梁接合金物を製作することはきわめて困難なた
め、柱・梁接合金物は鉄骨柱の内径よりやや小さめに形
成されるのが一般的である。However, since it is extremely difficult to manufacture a beam-to-column joint that completely adheres to the inside of the beam-to-column joint of a steel column, the column-to-beam joint is formed slightly smaller than the inner diameter of the steel column. Is common.
このため、柱・梁接合金物の全周を梁接合部の内側に
完全に密着させることがほとんど不可能なため、鉄骨柱
と柱・梁接合金物との間にどうしても隙間ができてしま
い、このためボルト孔の位置合わせ等が面倒になって接
合作業がしにくい等の課題があった。For this reason, it is almost impossible to completely adhere the entire periphery of the beam-to-column joint to the inside of the beam joint, and a gap is inevitably created between the steel column and the beam-to-column joint. Therefore, there has been a problem that the alignment of the bolt holes is troublesome and the joining operation is difficult.
この発明は、以上の課題を解決するためになされたも

形状に構成されている。The column / beam joint hardware 2 is provided with a plurality of beam joint steel plates 3 in the circumferential direction of the steel column 1 inside the beam joint of the steel column 1,
The adjacent beam-joined steel plates 3 are integrally connected to each other in the circumferential direction of the steel column 1 by a telescopic member 4 such as rubber which can be freely expanded and contracted to form a cylindrical shape having a diameter slightly smaller than the inner diameter of the steel column 1. I have.
したがって、柱・梁接合金物２は、伸縮部材４が柱・
梁接合金物２の周方向に伸び縮みすることにより、鉄骨
柱１の内径に応じてその径を自由に変えることができ

側に密着できるように断面略円弧状にそれぞれ形成さ
れ、さらにその上下両端部に接合ボルトを螺合するため
のねじ孔６が横方向に所定間隔に複数形成されている。Each beam-joined steel plate 3 is vertically elongated by casting or the like to have a length corresponding to the beam structure of the steel beam 5, and is formed in a substantially arc-shaped cross section so as to be able to adhere to the inside of the steel frame column 1. At both ends, a plurality of screw holes 6 for screwing the joining bolts are formed at predetermined intervals in the lateral direction.
このように構成された柱・梁接合金物２は鉄骨柱１の
梁接合部の内側に、工場などで、梁接合部に形成された
ボルト孔1aを貫通し、ねじ孔６に螺合される仮止めボル
ト11aと11bとによって予め仮付けされ、鉄骨柱１ととも
に現地に搬入される（第５図参照）。The column / beam joint hardware 2 configured as described above penetrates through the bolt hole 1a formed in the beam joint at the inside of the beam joint of the steel column 1 at a factory or the like, and is screwed into the screw hole 6. Temporarily fixed by the temporary fixing bolts 11a and 11b, and carried to the site together with the steel column 1 (see FIG. 5).

外側に突設されている。The beam joining bracket 7 is joined on site by screwing the bolt holes 7a of the beam joining bracket 7 and the bolt holes 1a of the steel column 1 into the same screw holes 6 after removing the temporary fixing bolts 11a and 11b. Bolts 8 protrude outside the beam joints of the steel column 1.
この場合、接合ボルト８を強く締め付けると、伸縮部
材４が柱・梁接合金物２の円周方向に自由に伸びるた

なる鉄骨柱１に自由に設置できるとともに、複数の梁接
合鋼板３によって梁接合部の剛性が著しく高められる。
なお、鉄骨柱１内には必要に応じてコンクリートが充填
されている。In this case, when the joint bolt 8 is strongly tightened, the elastic member 4 freely extends in the circumferential direction of the column / beam joint hardware 2, so that each beam joint steel plate 3 is completely adhered to the inside of the beam joint of the steel column 1. Therefore, the column / beam joint hardware 3 can be freely installed on the steel columns 1 of one kind and different in diameter, and the rigidity of the beam joint is significantly increased by the plurality of beam joint steel plates 3.
The steel column 1 is filled with concrete as needed.

７を介して一体的に接合されている。Also, the ends of the upper and lower flanges 5a of the steel beam 5 are bolted or welded to the upper and lower beam joining brackets 7 by a plurality of beam joining bolts 9 so that the end of the steel beam 5 is It is integrally joined to the outside of the beam joint via upper and lower beam joint brackets 7.
その際、フランジ5aの端部を梁接合ブラケット７に溶

９でボルト止めする。At this time, when the end of the flange 5a is welded to the beam joint bracket 7 to join the end of the steel beam 5, the beam joint bracket 7 is first welded to the end of the flange 5a and attached. First, the beam joint bolt 9 is bolted to the outside of the beam joint of the steel column 1.
なお、柱・梁接合金物２は、上下フランジ5aの端部が
接合される部分を必ずしも上下に連続した状態（第１図

４図の柱・梁接合金物２を、さらにフランジ5aの上側部
分と下側部分に別々に構成してもよい（第６図参照）。In addition, the column / beam joint hardware 2 does not necessarily need to be configured in such a manner that the portions where the ends of the upper and lower flanges 5a are joined are vertically continuous (see FIG. 1), and may be configured separately for upper and lower parts. (See FIGS. 3 and 4). In addition, the column / beam joint hardware 2 shown in FIGS. 3 and 4 may be separately formed on the upper portion and the lower portion of the flange 5a (see FIG. 6).

ったものである。FIG. 7 shows that the beam joining steel plate 3 is formed to be slightly thicker to increase the rigidity of the beam joining hardware 2, and that the joining bolt 8 is formed by interposing a filler 10 between the steel column 1 and the beam joining bracket 7. In order to improve the proof strength of the beam joint and to improve the construction, for example, the screw joint 6 can be screwed straight into the screw hole 6.

成は略同じである。FIG. 8 shows a steel beam 1 attached to a steel column 1 made of a square steel pipe.
FIG. 2 shows a column / beam joint metal fitting 2 for joining a steel plate, and in particular, is different from the previous embodiment only in that a beam joint steel plate 3 is formed in a flat plate shape so as to be in close contact with the inside of the steel column 1. The configuration is substantially the same.

け、接合ボルト８を強く締め付けて柱・梁接合金物２を
鉄骨柱１の梁接合部の内側に固定し、同時に梁接合ブラ
ケット７も鉄骨柱１の梁接合部の外側に突設する。When attaching the column / beam joint hardware, the column / beam joint hardware 2 is temporarily attached to the inside of the beam joint of the steel frame column 1 at a factory or the like using temporary fixing bolts 11a and 11b (fifth embodiment).
Then, the temporary fixing bolts 11a and 11b are sequentially pulled out at the site, and then the joining bolts 8 are screwed into the same screw holes 6 in order. At that time, the beam joint bracket 7 is also attached, and the joint bolt 8 is strongly tightened to fix the column / beam joint hardware 2 inside the beam joint of the steel column 1. At the same time, the beam joint bracket 7 is also attached to the beam of the steel column 1. Protrude outside the joint.
なお、各梁接合鋼板３の幅方向の中央部分にもねじ孔
６が形成されているときは、第２図に示すようにこのね
じ孔６を仮付け用のねじ孔として利用するほうが柱・梁
接合金物２の仮付けがし易い。When a screw hole 6 is also formed at the center in the width direction of each beam-joined steel plate 3, it is better to use the screw hole 6 as a screw hole for temporary attachment as shown in FIG. The beam joining hardware 2 can be easily tacked.
また、鉄骨梁５が梁接合部の一方向にしか接合されて
いない場合でも、各梁接合鋼板３の幅方向の両端部と中
央部とを梁接合部の内側にそれぞれボルト止めして固定
することにより、柱梁接合部の剛性を著しく高めること
ができる（第２図参照）。Even when the steel beam 5 is joined only in one direction of the beam joint, both ends and the center in the width direction of each beam-joined steel plate 3 are fixed to the inside of the beam joint by bolts. Thus, the rigidity of the beam-column joint can be significantly increased (see FIG. 2).

き、鉄骨梁を確実に接合できる。The column / beam joint hardware according to the present invention has the above-described configuration. In particular, since the diameter of the expandable member is freely changed by expanding and contracting in the circumferential direction of the steel column, the beam joint bolt is tightened. Accordingly, the steel column can be attached in a state of being completely adhered to the inside of the beam joint of the steel column, and the steel beam can be securely joined.
また、複数の梁接合鋼板とこの梁接合鋼板どうしを連
結する伸縮自在な伸縮部材からきわめて単純な形状に構
成されているため、製作し易く、量産化も可能である。Further, since it is formed in a very simple shape from a plurality of beam-joined steel plates and a telescopic member that can expand and contract the beam-joined steel plates, it is easy to manufacture and mass production is possible.
