Construction method of fabricated concrete superposed beam
The invention belongs to the field of assembly type concrete buildings, and particularly relates to a construction method of an assembly type concrete superposed beam, which comprises the following steps of: S1, assembling beam bottom longitudinal bars, prefabricated stirrups and constructional steel bars into a lower steel reinforcement cage assembly; s2, the bottom and the two sides of the lower reinforcement cage assembly are wrapped with steel wire mesh films; s3, the steel wire mesh film is coated with a cement protection layer, and a prefabricated U-shaped formwork is formed; s4, the upper longitudinal steel bars and the lap joint stirrups are assembled into an upper steel reinforcement cage assembly; and S5, the prefabricated U-shaped formwork is installed on site, then the upper reinforcement cage assembly is placed in a groove of the prefabricated U-shaped formwork, then concrete is poured, a concrete pouring body is formed, and production of the superposed beam is completed. Good firmness and stability can be guaranteed during installation and construction, compared with the prior art, the construction steps are simplified, longitudinal bars do not need to be inserted on site, the problem of insertion difficulty of the longitudinal bars is solved, the construction efficiency is greatly improved, and installation of the superposed beam is more efficient.
本发明属于装配式混凝土建筑领域，具体涉及一种装配式混凝土叠合梁的施工方法，包括以下步骤：步骤S1：将梁底纵筋、预制箍筋及构造钢筋组装成下钢筋笼组件；步骤S2：在下钢筋笼组件的底部和两侧包裹钢丝网膜；步骤S3：往钢丝网膜外涂覆水泥保护层，形成预制U型模壳；步骤S4：将上部纵向钢筋与搭接箍筋组装成上钢筋笼组件；步骤S5：现场安装预制U型模壳，再将上钢筋笼组件放置于预制U型模壳的凹槽上，然后浇筑混凝土，形成混凝土浇筑体，完成叠合梁的生产。本发明在安装施工时可以保证良好的牢靠性和稳定性，并且相比于现有技术简化了施工步骤，不需要在现场穿插纵筋，解决了穿插纵筋的困难，大大提高了施工效率，使叠合梁的安装更加高效。
