Concrete floor thickness controller and construction method

The invention relates to a concrete floor thickness controller and a construction method, and belongs to the technical field of building construction. The concrete floor thickness controller and the construction method are used for solving the problems that a traditional mode of controlling the thickness of a concrete floor through routing is inaccurate in height control, slow in project progress, prone to line slipping and the like. The concrete floor thickness controller comprises a tubular main body and a base, wherein the tubular main body is vertically arranged, the base is arranged at the bottom of the tubular main body, the tubular main body and the base are reinforced through stiffening ribs, the tubular main body, the base and the stiffening ribs are integrally formed through PVC materials, and the base is used for fixedly connecting the concrete floor thickness controller with a formwork. According to the concrete floor thickness controller, the floor thickness control has higher accuracy, the proje
