この発明は特に角形鋼管柱と鉄骨梁とからなる
鉄骨ラーメンの柱を構成する接合金物で接合した
鉄骨架構体形成用柱体に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention particularly relates to a column for forming a steel frame structure, which is made up of a square steel pipe column and a steel beam, and which is joined with a joining metal fitting.

Conventionally, in order to join a steel beam such as an H-shaped steel beam to a square steel pipe column, a joint bracket was fixed to the side of the joint of the square steel pipe column by welding for ease of on-site work, and the steel beam was connected to this joint bracket with bolts. The steel beams are either joined with a support plate or the steel beams are welded directly to the joint ends of the square steel pipe columns.

By the way, when a steel beam is joined to a square steel pipe column via a bracket, not only the number of parts such as the joining bracket and joining bolt increases, but also the amount of work on site increases accordingly. In this case, since the joint brackets are installed by welding mainly in the factory, the joint brackets become a hindrance when transporting from the construction site to the construction site, which not only greatly reduces transportation efficiency but also causes damage to the joint brackets. Sometimes. Furthermore, direct welding of steel beams to square steel pipe columns requires high construction precision, making it difficult to obtain product reliability on construction sites where work tends to be rough.

を確保している。 On the other hand, a joint plate 6 that contacts the side surface of the joint hardware 3 is fixed to the end of the steel beam 1 by welding, and a through hole 7 facing the screw hole 5 is formed in the joint plate 6 for use in beam joints. The bolt 4 is inserted into the through hole 7. Here, in order to realize tension bolt connection using bolts, the plate thickness of the connection plate 6 is as follows.
It is thicker than the flange web of the beam so that it can resist the various stresses that act on the beam end. Furthermore, the fixity of the column-beam joint is ensured by closely contacting the joint surfaces of the joint plate 6 and the joint hardware 3 with beam-joining bolts that introduce tension, that is, high-strength bolts.

れている。 3 and 4 show modified examples of the metal joint 3. In FIG. 3, the rigidity of the metal joint 3 is increased by forming a vertical stiffener 8 in the metal joint 3 with a substantially cross-shaped cross section. It is elevated. In addition, in Fig. 4, when the widths of the steel column and beam are the same or the column width is smaller than the beam width, the outer diameter of the joint hardware 3 is made slightly larger than the beam width of the steel beam 1. Workability has been improved by adding some margin to the width of the pillars and absorbing joint errors at the column-beam joints.
