MIXED CONSTRUCTION SKELETON OF REINFORCEMENT CONCRETE COLUMN AND STEEL BEAM

MIYAZAKI MITSUO

PROBLEM TO BE SOLVED: To provide a mixed construction skeleton of a reinforcement concrete column and a steel-constructed girder, which is a mixed construction skeleton of a reinforced concrete-constructed column and a steel-constructed beam, capable of rationally achieving a long-span structure, which enables free execution of column bar arrangement, and which enables concrete to be easily and reliably placed in a beam-column joint.SOLUTION: A steel-constructed beam is fixed in a face position on a column side surface, and a bearing plate is arranged at its end. A wide connection plate is attached to a flange end of the steel-constructed beam. The connection plates on both the sides of the column are integrated by being welded and joined together by means of a joint reinforcement, and fixed and anchored against flexural stress. Additionally, a PBL dowel with many holes, which is fixed to the bearing plate, is vertically arranged within a beam-column joint to transfer shear force of the beam to the beam-column joint.

【課題】長スパンの構造物を合理的に実現できるＲＣ造柱・Ｓ造梁の混合構造骨組で、柱配筋が自由にでき、柱・梁接合部のコンクリート打設も容易に確実に行える、鉄筋コンクリート柱とＳ造大梁との混合構造骨組を提供する。【解決手段】Ｓ造梁を柱側面のフェ−ス位置で止め、その端部に支圧板を配置する。Ｓ造梁のフランジ端部に幅の広い接続プレートを取り付け、柱両側の接続プレート同志を接合鉄筋を用いて溶接接合して一体化し、曲げ応力に対して固定・定着する。また支圧板に固定した多数の孔を有するＰＢＬジベルを柱・梁接合部内に鉛直方向に配置し、梁のせん断力を柱・梁接合部に伝達させる。【選択図】図２
