CONCRETE FRAME REMOVAL TIMING NOTIFICATION DEVICE AND CONCRETE CASTING METHOD
PROBLEM TO BE SOLVED: To provide a removal timing notification device enabling determination and notification on a removal timing of a concrete frame with a simple structure, and a concrete casting method using the same.SOLUTION: The removal timing notification device includes: a Seebeck element (thermoelectric conversion element) 610 that generates electric power using temperature difference; and a light-emitting device 620 that emits light using the electromotive force generated by the Seebeck element 610. The light-emitting device 620 is turned ON by generating electromotive force by the Seebeck element 610 using the temperature difference between inner temperature and surface side temperature in a concrete laid in a concrete frame 500. The light-emitting device 620 is configured to turn OFF when the temperature difference gets smaller to a predetermined temperature difference to thereby notify a user of the removal timing of the concrete frame 500.SELECTED DRAWING: Figure 3
【課題】コンクリート型枠の脱型時期を簡易な構成で判定・通知できる脱型時期通知装置を提供し、また、係る脱型時期通知装置を用いたコンクリートの打設方法を提供する。【解決手段】温度差に基づき発電するゼーベック素子（熱電変換素子）６１０と、ゼーベック素子６１０による起電力で発光する発光装置６２０とを有し、コンクリート型枠５００内に打設されたコンクリートの内部温度と表面側の温度との温度差に基づきゼーベック素子６１０で起電力を発生させて発光装置６２０を点灯させ、温度差が所定温度差にまで低下したときに発光装置６２０の消灯によってコンクリート型枠５００の脱型時期を通知するようにした。【選択図】図３
