PROBLEM TO BE SOLVED: To provide a control device for an upper surface level that may be fitted and removed easily and set an upper surface level stably regardless of a reinforcing bar size.SOLUTION: A control device 1 for an upper surface level is fitted at an intersection C of a reinforcing bar arrangement R having an upper reinforcing bar R1 and a lower reinforcing bar R2 that extend horizontally intersecting in a cruciform. The control device is of a loop form that alternately runs above and below the upper reinforcing bar R1 and the lower reinforcing bar R2 at the intersection C of the reinforcing bar arrangement R, and includes a bar fixing part 4 of which an end 4a is overlapped above and below the other end 4b and engaged, and a holding part 5 that holds a level setting rod material 2 while adjusting its vertical position, the level setting rod material serving as a mark for an upper surface.SELECTED DRAWING: Figure 1 |
