The invention provides a method for piercing the upper steel bar of a composite beam, which includes: A, installing stirrups and lower steel bars, and a prefabricated layer of the composite beam, in which the two ends of the prefabricated layer of the composite beam near the end region of the cast-in-situ column are overlapped by the stirrups above the prefabricated layer of the composite beam; B, installing the prefabricated layer of the composite beam, and opening the end region. The two ends of the stirrup are overlapped to form an opening allowing the upper reinforcement to be put in; C, the upper reinforcement to be pierced; D, the two ends of the open stirrup to be overlapped. In the present invention, the overlap of the two ends of the precast layer of the composite beam near the stirrups in the end region of the cast-in-situ column is located above the precast layer of the composite beam. When the precast layer of the composite beam is installed, the overlap of the two ends of the stirrups in the end region is opened, the upper steel bar can be easily inserted into the stirrups. Therefore, the upper steel bar of the composite beam can be easily inserted into the stirrups. The piercing method can conveniently pierce the upper steel bars of composite beams.

技术介绍
请参见图1、图2,授权公告号为CN207376646U的中国技术专利公开了一种叠合梁与现浇柱连接节点。叠合梁与现浇柱连接节点包括有现浇柱1和连接在现浇柱1上端两侧的叠合梁,叠合梁包括叠合梁预制层2和位于叠合梁预制层2上的叠合梁现浇层3,现浇柱1内设置有竖向钢筋4和围箍竖向钢筋4的第一方形箍筋5,两侧的叠合梁预制层2内均设置有沿着叠合梁长度方向延伸的梁底部钢筋6,两侧梁底部钢筋6的一端均伸出叠合梁预制层2进入现浇柱1内,两侧的叠合梁现浇层3内设置有沿着叠合梁长度方向延伸的贯穿两侧叠合梁现浇层3的梁顶部钢筋(上部钢筋)7,两侧的叠合梁现浇层3和现浇柱1通过现浇形成一个整体。箍筋5的两端搭接处100位于叠合梁现浇层内,在叠合梁现浇层安装后需要在箍筋5与叠合梁现浇层内穿设上部钢筋7,由于叠合梁的箍筋较为密集箍筋的间距在50mm至150mm之间,上部钢筋7为受力钢筋,上部钢筋7直径大,一般钢筋直径28~32毫米,而且上部钢筋7的数量多,另一方面现浇柱1预留的锚固钢筋也增 ...
