REINFORCEMENT COVERING DEPTH INSPECTION DEVICE AND METHOD FOR INSPECTING REINFORCEMENT COVERING DEPTH

摘要

PROBLEM TO BE SOLVED: To efficiently inspect whether or not a reinforcement covering depth formed between the inner surface of a form and reinforcements meets the requirement of the set value of a preset reinforcement covering depth before placing concrete using a simple device.;SOLUTION: Either of a first laser beam 2a or a second laser beam 3a, the separated distance of which is adjusted according to the set value and which are emitted parallel to each other is emitted along the inner surface 14a of the form, and whether or not the other laser beam passes between the inner surface of the form and the reinforcements without being interfered by the reinforcements is confirmed visually. When the two laser beams pass between the inner surface of the form and the reinforcements, and a laser spot occurs at the rear, the covering depth is determined to meet the requirement of the set value. The laser beams are emitted from the opened portion of the form. By changing the emitting angles of the laser beams, the reinforcement covering depth at a position apart from the opened portion can be inspected.;COPYRIGHT: (C)2011,JPO&INPIT
