NONDESTRUCTIVE INSPECTION METHOD FOR INSIDE OF REINFORCED-CONCRETE FLOOR SLAB
PROBLEM TO BE SOLVED: To provide a nondestructive inspection method of the inside of a reinforced-concrete floor slab capable of efficiently and accurately carrying out nondestructive inspection in the periphery of the haunch part of a floor slab.SOLUTION: In a nondestructive inspection method of the inside of a floor slab 104 for making a sensor part 12 opposite to a haunch part 106 connected to a main grinder 102 at the lower part of a floor slab 104 (reinforced concrete floor slab), and for emitting an electromagnetic wave to the haunch part 106, and for detecting a deterioration or failure of the inside of the floor slab 104 by using the reflection wave, an antenna part configuring the sensor part 12, and having a length which is substantially equal to the width in the shorter side direction of an inclined surface 110 configuring the haunch part 106, and exposed from the connection part to the main grinder 102 is made opposite to the inclined surface 110, and the sensor part 12 is brought into contact with the inclined surface 110 in a state that the longitudinal direction of the antenna part is directed to the shorter side direction, and the electromagnetic wave is emitted.SELECTED DRAWING: Figure 5
【課題】床版のハンチ部周辺において効率的かつ精度よく非破壊検査が可能な鉄筋コンクリート床版内部の非破壊検査方法を提供する。【解決手段】床版１０４（鉄筋コンクリート床版）の下部であって主桁１０２に接続するハンチ部１０６にセンサー部１２を対向させ、ハンチ部１０６に向けて電磁波を照射し、その反射波を利用して床版１０４の内部の劣化や欠陥を検出する床版１０４内部の非破壊検査方法であって、ハンチ部１０６を構成し主桁１０２との接続部分から露出した傾斜面１１０に対し、センサー部１２を構成し傾斜面１１０の短辺方向の幅と略同一の長さを有するアンテナ部を対向させるものとし、アンテナ部の長手方向を短辺方向に向けた状態でセンサー部１２を傾斜面１１０に接触させて電磁波を照射することを特徴とする。【選択図】図５
