Stair step construction joint jointing chiseling-free construction method
The invention discloses a stair step construction joint jointing chiseling-free construction method. The method comprises the following steps of (1) construction preparation, wherein a bottom die of aplate type stair is supported, and steel bars are laid from a plate end beam to a platform beam; (2) concrete pouring, wherein stair step concrete and concrete of the same layer structure are pouredtogether to the one-third position of the plate midspan, and a construction joint is reserved at the step internal corner; (3) film covering treatment, wherein after concrete pouring is completed, thesurface of the concrete outside the construction joint is covered with a plastic film immediately; (4) cleaning agent spraying, wherein after film covering treatment is completed, the cleaning agentis sprayed to the construction joint, and after uniform spraying, the construction joint is covered with the plastic film immediately; (5) construction joint blocking; and (6) flushing, wherein afterconcrete pouring is carried out for 12h, the stair construction joint is flushed while concrete curing is carried out. The method is efficient, low in cost and easy to operate, the problems of stair step construction joint jointing secondary chiseling and joint garbage cleaning are effectively solved, practicability is high, and popularization is facilitated.
本发明公开了一种楼梯踏步施工缝接茬免凿毛施工方法，包括以下步骤：（1）施工准备：支板式楼梯的底模，铺设钢筋从板端梁至平台梁；（2）混凝土浇筑：楼梯踏步混凝土与同层结构混凝土一起浇筑，浇筑至板跨中三分之一处，在踏步阴角处留施工缝；（3）覆膜处理：混凝土浇筑完成后，立即对施工缝以外的混凝土表面进行覆盖塑料膜；（4）喷洒清洗剂：覆膜处理完成后，对施工缝进行清洗剂喷洒，喷洒均匀后，立即用塑料膜覆盖；（5）施工缝封堵；（6）冲洗：待混凝土浇筑12h后，在对混凝土养护的同时，冲洗楼梯施工缝。本发明高效，低成本，操作简单，有效解决楼梯踏步施工缝接茬二次凿毛、清理接缝处垃圾存在的问题，实用性强，利于推广。
