Construction method of reserved hole in cast-in-place floor plate
The invention discloses a construction method of a reserved hole in a cast-in-place floor plate. The problems that a mold of an existing reserved hole cannot be repeatedly used, and the construction cost is high are solved. A stand column (1) is vertically arranged at the center of a reserved hole (22) in a floor plate pouring bottom formwork (23), a lower limiting pin hole (4) is formed in the lower portion of the stand column (1), the stand column above a cylindrical lower limiting step (2) is movably sleeved with a fourth lantern ring (11), the stand column above the fourth lantern ring (11) is movably sleeved with a lower compression spring (7), and the lower compression spring (7) is sleeved with a lower limiting pin hole (8). A third lantern ring (10) is movably sleeved on the upright post above the lower pressure spring; cantilever rods are radially arranged on the two lantern rings, lower arc-shaped vertical plates are hinged to the outer ends of the corresponding upper and lower cantilever rods, the lower arc-shaped vertical plates are spliced into a vertical circular sleeve, and the vertical circular sleeve is internally supported on the inner side face of an iron sheet sleeve (20); field construction is simple, and the construction cost is greatly reduced.
本发明公开了一种现浇楼层板上的预留孔洞的构筑方法，解决了现有预留孔洞存在的模具不能重复使用和施作成本高的问题；在楼层板浇筑底模板（23）上的预留孔洞（22）的中心处，竖直设置有立柱（1），在立柱（1）下部设置有下限位销孔（4），在圆柱形下限位台阶（2）上方的立柱上活动套接有第四套环（11），在第四套环（11）上方的立柱上活动套接有下压簧（7），在下压簧上方的立柱上活动套接有第三套环（10）；在两套环上放射形布置有悬臂杆，对应的上下两悬臂杆的外端铰接有下弧形立板，各下弧形立板拼接成立式圆形套筒，立式圆形套筒内撑在铁皮套筒（20）的内侧面上；现场施作简单，大大降低了施工成本。
