CONCRETE INSTALLATION HEIGHT MEASURING APPARATUS
PROBLEM TO BE SOLVED: To provide a concrete installation height measuring apparatus which is capable of easily measuring an installation height of ready mixed concrete under installation and can be utilized even in a case where a job site is filled with water.SOLUTION: A concrete installation height measuring apparatus 1 comprises a height detection cable 2 consisting of paired wires, a current measuring instrument 31 for measuring a current that flows in the cable, a data transmitter 34 for transmitting measurement data, and the like. One lead wire of the height detection cable 2 includes multiple resistors that are connected in series, and short-circuiting means for short-circuiting the wires with a liquid pressure of ready mixed concrete. The height detection cable 2 is disposed along a reinforcing-bar or the like on the job site and when installing ready mixed concrete, the short-circuiting means short-circuits the paired wires with the liquid pressure of the ready mixed concrete. The current measuring instrument 31 measures a current that flows through the paired wires, and calculates a height of installed concrete.SELECTED DRAWING: Figure 1
【課題】本発明の目的は、打設中の生コンクリートの打設高さを容易に測定でき、現場が水で満たされている場合も利用可能なコンクリート打設高さ測定装置を提供する。【解決手段】コンクリート打設高さ測定装置１は、ペアの電線からなる高さ検知ケーブル２、それを流れる電流を測定する電流測定器３１、測定データ送信するデータ送信機３４等からなる。高さ検知ケーブル２の一方の導線は、直列で接続された複数の抵抗器と、生コンクリートの液圧で電線を短絡させる短絡手段を有する。高さ検知ケーブル２は、コンクリート打設現場で鉄筋等にそって配置され、生コンクリートが打設されるとき、その液圧で、短絡手段がペアの電線を短絡させる。電流測定器３１はペアの電線を流れる電流を測定して、打設コンクリートの高さを求める。【選択図】 図１
