Description
【０００１】[0001]
本考案は鉄骨造又は鉄骨鉄筋コンクリート造建物の鉄骨柱と鉄骨柱の接合部構 造に関する。 The present invention relates to a joint structure between steel columns and steel columns of a steel frame structure or a steel frame reinforced concrete building.
【０００２】[0002]
従来、鉄骨柱と鉄骨柱との接合は、図１５、図１６に示す方法で行なわれてい た。先ず接合しようとする鉄骨柱６の裏側に裏当金１５を当接して固定する。次 に鉄骨柱６と鉄骨柱１とを接合治具１６により固定した後、溶接により柱１、６ を接合１７する。 また、実開昭６２−３８３０４号公報には、はりと接合する仕口部用の金物の 上部に、柱と接合する金物を締結した、柱と柱接合装置が記載されているが、鉄 骨柱どうしの接合に関するものではない。 Conventionally, the steel column and the steel column are joined by the method shown in FIGS. 15 and 16. First, the backing plate 15 is abutted and fixed to the back side of the steel column 6 to be joined. Next, the steel columns 6 and the steel columns 1 are fixed by a joining jig 16, and the columns 1 and 6 are joined 17 by welding. Further, Japanese Utility Model Laid-Open No. 62-38304 discloses a pillar-to-column joining device in which a fitting to be joined to a beam is fastened to an upper portion of a fitting to be joined to a beam. It is not about joining columns together.
【０００３】[0003]
上記従来の接合方法は、建築現場での屋外溶接作業となるので、溶接作業時の 天候等により接合部の品質が左右されてばらつきがある。また、溶接作業工数以 外に、鉄骨柱へ裏当金と接合治具の取付け、溶接接合完了後に接合治具の除去等 の実質作業以外の付帯作業工数を必要とするが、建築現場にてこのような多大の 工数を要すると工期の遅延を招く恐れがある。 従って本考案は、建築現場にて鉄骨柱と鉄骨柱を接合するに際し、溶接作業を なくして溶接接合部の品質の安定性向上を図ると共に、接合作業の簡略化、作業 時間の短縮等を目的とする。 Since the above-mentioned conventional joining method is an outdoor welding work at a construction site, the quality of the joint varies depending on the weather at the time of the welding work. In addition to the man-hours required for welding, additional man-hours other than the actual work such as attaching the backing metal and joining jig to the steel column and removing the joining jig after welding and joining are required at the construction site. If such a large number of man-hours are required, the work period may be delayed. Therefore, the present invention aims to improve the stability of the quality of the welded joint by eliminating the welding work when joining steel columns to each other at a construction site, simplify the joining work, and shorten the work time. And
