れ対向的に取り付けられている。 In FIGS. 1 and 2, the upper steel frame 1 and the lower steel frame 2 face each other with a root interval of 3, and the groove shape of the butt joint 4 is formed in a rectangular shape. A connecting ring 5 is attached to the upper side and a connecting piece 6 is attached to the lower side of the steel frames 1 and 2, respectively, on the inner surfaces of the opposite ends of the steel frames 1 and 2.
連結環５は平面コ字状に形成され、両端部は鉄
骨材１の内側面に溶接により固着されている。 The connecting ring 5 is formed into a U-shape in plan, and both ends are fixed to the inner surface of the steel frame 1 by welding.

分は内側面とは所定の間隙７があけられている。 The connecting piece 6b extends upward from the receiving part 6c of the connecting piece 6.
has been extended. The connecting piece 6b is formed to be thin, curved outward, and elastically deformable, and is inserted into the connecting ring 5. The upper end of the connecting piece 6b is in elastic contact with the inner surface of the steel frame material 1, but a predetermined gap 7 is left between the other portions and the inner surface.

部に当接して、その位置が保持される。 A notch 6d is provided in the center of the upper end of the connecting piece 6 downward from the upper end surface, and a wedge 8, which is a fixing piece, is driven into the gap 7 using this notch as a guide. 6b is pressed to fix the connected state between the connecting ring 5 and the connecting piece 6. The head 8a of the wedge 8 comes into contact with the bottom of the notch 6d and is held in that position.
次に作用について説明する。 Next, the effect will be explained.
予め、鉄骨材１と鉄骨材２とにそれぞれ連結環
５と連結片６とをそれぞれ取り付けておく。 In advance, a connecting ring 5 and a connecting piece 6 are attached to the steel frame 1 and the steel frame 2, respectively.

れる。 Therefore, first, the lower steel frame 2 is erected, then the upper steel frame 1 is suspended, and the lower end is lowered toward the upper end of the lower steel frame.
The connecting piece 6b of the connecting piece 6 is inserted, and as it descends further, the connecting ring eventually rides on the receiving part 6c of the connecting piece, and at this stage the lowering of the upper steel frame material is stopped. As a result, the root spacing 3 between the steel frames is maintained.

接して両鉄骨材１，２間を接合する。 Thereafter, a wedge 8 is driven into the gap 7 through the notch 6d at the upper end of the connecting piece 6 to fix the connected state between the connecting ring 5 and the connecting piece 6, and then connect it to the inside of the joint 4 as shown by the chain line in FIG. Place the back plates 9, 9 across the piece 6.
a are temporarily attached, and finally these joints are fully welded to join both steel frames 1 and 2.

る部分には同一符号を付してある。 In this example, an insertion recess 6e of the back plate is formed at a position facing the butt joint 4 on the mounting surface of the mounting portion 6a of the connecting piece 6, extending over the entire width in the width direction. Therefore, before the main welding of the butt joint 4, one back plate 9b is passed through the insertion recess 6e, and this back plate is temporarily fastened to close the butt joint 4. The other structures and operations in this example are substantially the same as in the above example, so corresponding parts are given the same reference numerals.

る。(Effects of the Invention) As explained above, according to the present invention, the spacing between the opposing ends of the steel frame can be secured by the connecting ring and the connecting piece, and the specially machined spacing piece can be omitted, so the processing can be done accordingly. It does not take much time, and the work to secure the spacing can be done at the same time as the connection, reducing the work involved in joining the steel frames. Since the connecting piece is provided with an insertion recess through which the back plate is inserted, only one back plate is required, which reduces the number of welded parts of the back plate, and improves work efficiency.
