【考案の詳細な説明】 《産業上の利用分野》 本考案は柱梁の仕口構造に係り、特に鉄筋コンクリー
ト柱と鉄骨梁とで構成する多層建築物において梁のスパ
ン長の長大化を実現する柱梁の仕口構造に関する。[Detailed description of the invention] << Industrial application field >> The present invention relates to a beam-to-column connection structure, and in particular, increases the span length of a beam in a multi-story building composed of reinforced concrete columns and steel beams. The connection structure of columns and beams.
《従来の技術》 柱梁ともに鉄筋コンクリート造および鉄骨鉄筋コンク
リート造では何れの場合にも柱梁仕口部に鉄筋を組む必
要があり、これらの鉄筋は柱と梁の双方に荷重を伝えあ
うようにしている。《Conventional technology》 In both cases, in both reinforced concrete and steel reinforced concrete construction, it is necessary to assemble a reinforcing bar at the beam-to-column connection, and these reinforcing bars transmit loads to both the column and the beam. I have.
そのために仕口部分に入り組む鉄筋は数や形状の点で
複雑になり、施工の簡略化という観点からは難点の一つ
になっていた。For this reason, the reinforcing bars entering the connection portion are complicated in terms of number and shape, and have been one of the difficulties in terms of simplification of construction.
そこで、特開昭59−179946号や特開昭63−103140号が
提供されている。Therefore, JP-A-59-179946 and JP-A-63-103140 are provided.
すなわち、梁を鉄骨とするものであり、鉄筋コンクリ
ート柱と鉄骨梁とで建物を構成するものであった。That is, the beam is made of steel, and the building is composed of reinforced concrete columns and steel beams.
《考案が解決しようとする課題》 最近の地価上昇と相俟って室内空間の使用上のフレキ
シビリティを向上させる目的で柱を少なくしたり、柱の
断面積を小さくすることが必要になっている。《Problems to be solved by the invention》 In conjunction with the recent rise in land prices, it is necessary to reduce the number of pillars and the cross-sectional area of pillars in order to improve the flexibility in the use of indoor space. I have.

も、より長大なスパン長を得るためには柱梁の断面を増
加せざるを得なかった。In order to respond to this need, long span beams are used to increase the span between columns, and at the same time, steel beams are used to maintain the strength of the beam-to-column connections, and stud bolts at the ends of the steel beams are used. Even if the degree of contact between the column and the concrete is increased or the steel plate hoop and the steel beam that restrains the connection are combined, in order to obtain a longer span length, the section of the column and beam must be increased. Did not get.
このような断面増しを避けるためにはブレースを用い

レースのように接合部において応力集中を生じる部材は
ブリックな破壊モードとなる鉄筋コンクリートとの併用
を避けるほうが無難なので、結局ブレースを用いること
はなく、柱梁の断面を増していたのである。It is not often mixed as a main structural material, and it is safer to avoid using materials such as braces that cause stress concentration at the joints with reinforced concrete that is in a brick failure mode, so no braces are used after all, The cross section of the beam was increased.

A gusset plate for joining one end of a brace connected to at least one of the upper and lower steel beams than the steel beam was fixed to the intersection between the steel beams and the outer steel plate hoop. Therefore, in addition to improving the toughness and proof strength of the joint, the concentrated stress received from the brace is transmitted to the entire iron plate hoop, and the position of the iron plate hoop corresponds to the column base (joint), and stress is applied to the beam. Has the effect of effectively increasing the span length without increasing the cross-sectional area of the beam by introducing a brace frame into the composite structure of reinforced concrete columns and steel beams.
