Prefabricated concrete main beam and cast-in-place secondary beam connecting structure and construction method thereof
The invention provides a prefabricated concrete main beam and cast-in-place secondary beam connecting structure. The prefabricated concrete main beam and cast-in-place secondary beam connecting structure comprises a prefabricated concrete main beam and a cast-in-place secondary beam and a connecting piece, wherein the prefabricated concrete main beam is provided with a mounting position, a bent anchor steel bar is mounted on the top wall of the mounting position, a pre-buried hole is formed in the side wall of the mounting position, and a pre-buried straight thread sleeve is arranged in the pre-buried hole; the cast-in-place secondary beam is mounted at the mounting position, the cast-in-place secondary beam comprises a steel bar framework and cast-in-place concrete, the upper longitudinal bar connecting end of the steel bar framework is connected with the bent anchor steel bar, the lower longitudinal bar connecting end of the steel bar framework is provided with a lower bar external thread, the lower longitudinal bar connecting end is inserted into the pre-buried hole, and the lower bar external thread is in threaded connection with the pre-buried straight thread sleeve; the cast-in-place concrete wraps and fills the mounting position and the steel bar framework. According to the prefabricated concrete main beam and cast-in-place secondary beam connecting structure, the pre-buried straight thread sleeve is arranged on the side wall of the mounting position and connected with a lower longitudinal bar of the cast-in-place secondary beam, the bent anchor steel bar is pre-buried on the top wall of the mounting position, the straight section end of the bent anchor steel bar is connected with an upper longitudinal bar of the cast-in-place secondary beam, the connecting effect is guaranteed, and the cast-in-place secondary beam and the prefabricated concrete main beam form a stable whole.
本发明提供预制混凝土主梁与现浇次梁连接结构，包括：预制混凝土主梁，其上有安装位，在安装位的顶壁安装有弯锚钢筋，在安装位的侧壁开设有预埋孔，在预埋孔中设置有预埋直螺纹套筒；现浇次梁，其安装在安装位处，现浇次梁包括钢筋骨架和现浇混凝土，钢筋骨架的上部纵筋连接端与弯锚钢筋连接，钢筋骨架的下部纵筋连接端设有下筋外螺纹，下部纵筋连接端插入预埋孔中且下筋外螺纹螺纹连接在预埋直螺纹套筒中；现浇混凝土包裹并填充安装位和钢筋骨架。本发明安装位侧壁设置预埋直螺纹套筒与现浇次梁下部纵筋相连接，安装位顶壁预埋弯锚钢筋，弯锚钢筋平直段端头与现浇次梁上部纵筋连接，保证了连接效果，使现浇次梁与预制混凝土主梁形成稳固整体。
