Construction method for precisely locating and mounting reserved steel bars in cast-in-place concrete bottom plate

The invention provides a construction method for precisely locating and mounting reserved steel bars in a cast-in-place concrete bottom plate. The method comprises the steps that a foundation of a concrete structure is arranged on the side of the cast-in-place concrete bottom plate, and a steel bar locating base is mounted on the foundation; the precise requirement for steel bar locating is met by adjusting the plane position and flatness of the steel bar locating base; the double-row steel bars on the outer side and in the middle are located through U-shaped grooves formed in the steel bar locating base; the steel bars on the inner side are located through rib plate connection; and concrete pouring of the concrete bottom plate is achieved through rib plate clearances. The method is simple in operation process and adopted equipment, low in construction cost and high in speed. 本发明提供的现浇混凝土底板中预留钢筋精确定位、安装的施工方法是在现浇混凝土底板边侧设置混凝土结构的基础，将钢筋定位基座安装在基础上；通过调整钢筋定位基座的平面位置及平整度来实现对钢筋定位的精确要求；通过钢筋定位基座上设置的U形槽来实现对外侧及中部双排钢筋的定位；通过肋板
