2. Description of the Related Art When a square steel pipe is used as a column material and an H-shaped steel is used as a beam material, the joint between the two, which is also called a joint, withstands a large bending moment beyond the yield of the flange portion of the beam material. It must be designed to gain. For this reason, it is necessary to use high-strength bolts as the bolts at the joints, but since the pillar material has a closed cross section, the bolt heads inside the pillar cannot be fixed or tightened, and some kind of ingenuity is required. And Moreover, the plate thickness of the square steel pipe is not sufficient,
Reinforcement may be required at the joint.

FIG. 1 shows a lower column member unit, 1 is a lower column member made of square steel pipe, 2 is a diaphragm attached inside thereof, 3 is a T-shaped metal object for attaching a beam member,
This is the so-called “split T”. Since the diaphragm transmits the horizontal force acting from the flange of the beam to the column, it is necessary to attach the diaphragm to the position where the flange of the beam is extended. Since the upper end of 1 is the upper surface of the beam member, the mounting height of the diaphragm 2 and the T-shaped metal member 3 is a position lower than the upper end of the lower column member 1 by the amount of the beam member. In the steel frame processing factory, first, the flange portion of the T-shaped metal 3 is securely fastened to the outer surface of the pillar 1 by the high-strength bolt so that the web portion of the T-shaped metal 3 has this mounting height, and then the diaphragm 2 is welded. Install by. Since the mounting position is close to the end of the pillar, these mounting operations are not particularly difficult.

As is clear from the above description, in the present embodiment, the connecting positions of the pillar members are substantially aligned with the mounting positions of the beam members, and the T-shaped metal members 6 and 7 are spread over the upper and lower pillar members. It is attached, and at the same time as connecting the pillar and beam, it also plays the role of a connecting metal for the upper and lower pillars. By the way, for the high-strength bolts 12 and 13, it is necessary to perform the final tightening with only the heads of the bolts exposed to the outer surface.
For example, the nut is placed inside, a U-shaped rotation washer, a washer with a tongue, etc. are inserted into the nut to hold down the co-rotation, and the bolt is turned from the outside to tighten. Fixing the nut on the inner surface by adhesion or welding is not preferable because it restricts the position adjustment of the T-shaped metal object.

It should be noted that, by reversing the vertical relationship with this embodiment,
That is, a similar joint structure can be realized even if the vertical connection position of the column is substantially aligned with the lower flange of the beam member. Also,
In the above description, the lower pillar material and the upper pillar material are different for convenience, but in reality, these are one continuous pillar material, and when the upper pillar material is built up, it is one step higher. Needless to say, the lower pillars of the building are being built.
