APPARATUS AND METHOD FOR DISPLAYING CONCRETE COMPACTING POSITION

摘要

PROBLEM TO BE SOLVED: To perform proper concrete compacting work without depending on the seat-of-the-plants of a supervisor and a worker.;SOLUTION: This apparatus comprises: a plurality of light-emitting devices 51 which are installed in positions where compaction is to be performed; a light-emission control means 13 for controlling the light emission of the light-emitting device 51 depending on the progress of the placing of concrete; and a light-emission stop switch 52 which is operated by the worker, so as to stop the light emission of the light-emitting device 51 on the completion of the compaction. The light-emission control means 13 brings about the sequential light emission of the light-emitting device 51 to subsequently emit the light, when instructions on the stop of the light emission of the light-emitting devices 51 are issued by the light-emission stop switch 52. Additionally, the light-emission control means 13 gives an alarm without turning off the light from the light-emitting devices 51, when the light-emission stop switch 52 is operated before a lapse of a set minimum compaction time.;COPYRIGHT: (C)2008,JPO&INPIT
