Title:
VIBRATION COMPACTION OF CONCRETE DETECTOR
Document Type and Number:
Japanese Patent JP2019065695
Kind Code:
A
Abstract:
To provide a detector capable of detecting correctly and notify that concrete is compacted sufficiently by a vibration compaction without a need of an external power supply.SOLUTION: In a mount member 10 mountable to an outer side surface of a mold foam 101 in which concrete 102 is installed, a vibration V transmit in concrete is received from a vibration compaction machine 103 inserted in uncured concrete installed in the mold frame 101 and a vibration detection signal is generated and a vibration detection part (piezoelectric element) which serves as a vibration power generation part for generating an electric power by this vibration detection signal as well, a battery for reserving electric power generated by the vibration power generation part and a determination part which is driven by an electric power from the battery, measures the electric power charged to the battery and drives a notification part 13 by the electric power of the battery at a point when a measured value reaches to a preset threshold value are provided.SELECTED DRAWING: Figure 1
