取付けられている。 As shown in FIG. 1, in advance, one end of the beam steel frame 2 with a length of one span is attached to the side surface of the flange 1A of the column steel frame 1, and a tightening bolt 4 is attached to the bracket 3 protruding from the flange 1A. It is temporarily fixed so that it can swing in the direction of the arrow (clockwise). Tightening bolt 4
is screwed into a female threaded pipe 5 which is fixed to the flange 2A of the beam steel frame 2 by welding, as shown in FIGS. 1 and 2. The beam steel frame 2 is attached to the side surface of the column steel frame 1 so as to be able to swing around a fastening bolt 4 .
柱鉄骨１の他側面にも上記と同一構成の梁鉄骨
を揺動可能に取付けておく。 A beam steel frame having the same configuration as above is also swingably attached to the other side of the column steel frame 1.

部とを溶接接合する。 The method of constructing the column steel frame 1 and beam steel frame 2 is as follows:
As shown in Figure 3A, the beam steel frame 2 is temporarily fixed in a closed state along the column steel frame 1, and the column steel frame is lifted by a tower crane, and the column steel frame is erected and installed. As shown in Figure 3B, the column steel frame 1 is sequentially swung in the direction of the arrow from the beam steel frame located below.
Stop rocking when it becomes perpendicular to the
After that, the tip of the beam steel frame is connected to the adjacent column steel frame and welded together. Further, the ends of the column steel frame 1 and the beam steel frame 2 are welded together.

平面上の全ての梁のセツトが可能となる。 Depending on the installation location of the column steel frame 1, the beam steel frame 2 may be attached only to one side of the column steel frame. Then, the column steel frame 2 is temporarily fixed to only one side, and the column steel frame 1 is temporarily fixed to both sides.
By arranging as shown in Figure 3D,
All beams on the plane can be set.
