COVER THICKNESS MEASUREMENT DEVICE OF REINFORCEMENT
PROBLEM TO BE SOLVED: To realize a cover thickness measurement device of a reinforcement capable of measuring a cover thickness of an optional reinforcement.SOLUTION: A measurement point abutting member 30 installed in a tip part 12 of a rod-like member 10 is inserted between a reinforcement R of a measurement object and a form W, and an abutting plate 32 is allowed to abut on its reinforcement R. A distance measurement is executed by a laser distance gauge 20 arranged in a first position for irradiating a laser beam toward a mirror surface 40a of a mirror 40, and a distance L1 is measured up to the form W corresponding to an optical path bending the laser beam by 90° by the mirror 40. The distance measurement is also executed by the distance measurement by the laser distance gauge 20 arranged in a second position for irradiating the laser beam toward a reference plate 31, and a distance L2 is measured up to the reference plate 31. Since a dimension provided by subtracting the distance L2 from the distance L1 provided by such a measurement is a cover thickness of the reinforcement corresponding to a distance between the reinforcement R and the form W, the cover thickness of an optional reinforcement R of becoming a measurement object can be measured by using a cover thickness measurement device 100 of the reinforcement.SELECTED DRAWING: Figure 1
【課題】任意の鉄筋のかぶり厚を計測することができる鉄筋のかぶり厚計測装置を実現する。【解決手段】棒状部材１０の先端部１２に取り付けられている計測点当接部材３０を計測対象の鉄筋Ｒと型枠Ｗの間に挿し入れ、その鉄筋Ｒに当接板３２を当接させる。そして、鏡４０の鏡面４０ａに向けてレーザー光を照射する第１の位置に配したレーザー距離計２０による測距を行い、鏡４０でレーザー光を９０°曲げた光路に対応する型枠Ｗまでの距離Ｌ１を計測する。また基準板３１に向けてレーザー光を照射する第２の位置に配したレーザー距離計２０による測距による測距を行い、基準板３１までの距離Ｌ２を計測する。こうした計測によって得られた距離Ｌ１から距離Ｌ２を減算して得られる寸法が鉄筋Ｒと型枠Ｗの間の距離に相当する鉄筋のかぶり厚であるので、鉄筋のかぶり厚計測装置１００を用いれば、計測対象となった任意の鉄筋Ｒのかぶり厚を計測することができる。【選択図】図１
