VIBRATION COMPACTION DETECTION DEVICE OF CONCRETE
PROBLEM TO BE SOLVED: To provide a detection device which can exactly detect and notify that concrete is sufficiently compacted by vibration compaction without the need for an external power supply.SOLUTION: A vibration power generation part, a vibration detection part which receives vibration V propagated in concrete 102 from a vibration compaction machine 103 which is inserted into uncured concrete placed in a concrete form 101 to generate a vibration detection signal, and a determination part which is driven by the power of the vibration power generation part are arranged at an attachment member 10 which can be attached to an outside face of the concrete form 101 for placing the concrete 102 therein. The determination part determines a finish time of vibration compaction on the basis of the vibration detection signal, and drives a notification part 13.SELECTED DRAWING: Figure 1
【課題】外部電源を必要とせずに、コンクリートが振動締め固めによって十分に締め固まったことを的確に検知し報知することが可能な検知装置を提供する。【解決手段】コンクリート１０２を打設する型枠１０１の外側面に取り付け可能な取付部材１０に、振動発電部と、型枠内に打設された未硬化のコンクリートに挿入した振動締め固め機１０３からコンクリート１０２中を伝播される振動Ｖを受振して振動検出信号を発生する振動検出部と、振動発電部の電力により駆動する判定部が設けられ、判定部は、振動検出信号に基づいて振動締め固めの完了時期を判定して報知部１３を駆動させるものである。【選択図】図１
