<P>PROBLEM TO BE SOLVED: To provide an estimated covering depth checking device capable of checking that an estimated covering depth is a desired covering depth by checking an interval between a reinforcing bar and a form inner face before placing concrete. <P>SOLUTION: The estimated covering depth checking device is for checking a covering depth estimated in a reinforced concrete structure to be formed by an interval between a form and a reinforcing bar before placing concrete, and includes: a roller which has a diameter that is a desired covering depth and has a width equal to or larger than the diameter; and an operation part which freely turnably supports the roller, is formed in a width narrower than the diameter in the diameter direction of the roller, and is operated in order to move the roller between the form and the reinforcing bar. <P>COPYRIGHT: (C)2013,JPO&INPIT |
