For concrete floor slabs, the flatness of the ceiling is generally determined by the flatness of a wood template before the floor slabs are poured, the elevation and flatness control difficulty is low, for building industrialization projects, most floor slabs are prefabricated composite floor slabs, and the floor slabs are combined with cast-in-place concrete after being hoisted, assembled and poured, but as the prefabricated parts of the floor slabs are formed by assembling the composite floor slabs, the floor bottom surface, the top surface of the next floor, the elevation and the flatness are easy to have larger errors, and the reason is mainly caused by construction and installation quality problems. When the composite floor slab is hoisted, the working range of a constructor is mainly in the composite floor slab, the corresponding floor slab installation quality control is also carried out on the top surface of the composite floor slab, and the bottom surface of the composite floor slab, namely the ceiling of the next floor, is often concealed by a wood template in visual angle or lacks corresponding elevation and flatness control devices because of measurement and inconvenient action, and finally leads to the problem of ceiling flatness caused by the non-uniform elevation at the splicing position of the adjacent composite floor slabs.

When the composite floor slab is hoisted, the working range of a constructor is mainly on the top surface of the composite floor slab, and meanwhile, a measurement control device for the bottom surface of the composite floor slab is lacked, so that the rechecking and correction of the installation quality of the top surface of the composite floor slab are only completed under the normal condition, and the problems of local elevation deviation and flatness of the bottom surface of the composite floor slab are caused. However, the measurement of the bottom surface of the composite floor slab is limited by the full scaffold and the wood formwork in the construction floor, most of constructors directly ignore or adopt a visual method, a laser range finder and the like, but the visual method has large deviation and is influenced by subjectivity of different individuals, and the laser range finder is influenced by the flatness of a measurement starting point (floor level).
