The invention discloses a construction method for controlling the surface flatness of a cast-in-place concrete slab. A guiding rail bracket is arranged on a construction siteand a guiding rail is laid, after completion of concrete pouring, afloating ruler is used for scraping and laying concrete along the guiding rail, the elevation error of the guiding rail is adjusted, the concrete is scraped and laid again by using the floating ruler until the surface flatness of the cast-in-place concrete slab meets the design requirements. According to the construction method for controlling the surface flatness of the cast-in-place concrete slab, field operability is high, and the surface flatness of the cast-in-place concrete slab can be controlled to meet the design requirements. 本发明公开了种控制现浇混凝土平板表面平整度的施工方法，在施工现场设置导轨支架并铺设导轨，在混凝土浇筑完成后使用刮尺沿导轨刮铺混凝土，并调整导轨标高误差，再次使用刮尺刮铺混凝土，直至现浇混凝土平板的表面平整度达到设计要求。本发明提出的控制现浇混凝土平板表面平整度的施工方法，现场可操作性强，能够控制现浇混凝土平板的表面平整度达到设计要求。
