Regarding.

(Prior Art) In the construction of concrete floor surfaces, the work performed before the concrete hardens is conventionally performed as follows.

First, reinforcing bars are assembled into a formwork that constitutes a floor surface, and concrete is poured into the formwork from a flexible hose or the like, or concrete is poured into a recess corresponding to the floor surface.

Next, fill and compact concrete with a vibrator or the like as necessary.

Next, the worker performs rough leveling work while adjusting the amount of excess or shortage of concrete using a leveling jig.

Finally, the worker levels the floor surface, and uses a ruler rod to level the top and perform ruler-by-shape tasks such as leveling the top and correcting the gaps.

This conventional method requires highly skilled workers, especially for the work after leveling, so if the floor area is large, it is necessary to secure a large number of skilled workers, and it is also necessary to have a large number of skilled workers. Even if there were, there were problems such as variations in finishing accuracy depending on the worker, and furthermore, the work took a long time.
