設置されるＰＣ部材と一体接合されたことに存する。The gist of the PC beam of the present invention for achieving the above object is to provide a PC beam having a steel beam member at the center and reinforced concrete beam members at both ends. A fixing plate is provided at an end of the steel beam member embedded in the reinforced concrete beam member, and a joining bar whose tip is arranged in a panel zone of the reinforced concrete column is fixed to the fixing plate, and an end of the steel beam member is fixed. The reason is that the band plate is wound around the beam main reinforcement of the reinforced concrete beam member which overlaps at appropriate intervals, and the reinforced concrete beam member is integrally joined with the PC member installed in the panel zone of the reinforced concrete column.

Since the band plate is wound around the beam reinforcing bars of the reinforced concrete beam member at appropriate intervals, stress is smoothly transmitted at the joint between the reinforced concrete beam member and the steel beam member. In addition, since the reinforced concrete beam member is integrally joined with the PC member installed in the panel zone of the reinforced concrete column, difficult reinforcing work in the panel zone can be omitted, so that the beam and the column can be easily joined. Shortening can be achieved.
