Title:
CONDITION MEASURING INSTRUMENT FOR CONCRETE
Document Type and Number:
Japanese Patent JP3575008
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a condition measuring instrument for concrete that can measure impulsive vibrating and sound receiving at a plurality of points of measurement under the same condition.
SOLUTION: In this condition measuring instrument, a plurality of condition measuring apparatuses 11 each of which is constituted of a hammering sound generating means which strikes the surface of concrete C, a hammering sound collecting means which collects hammering sounds, and a condition measuring means which measures the condition of the concrete C of which at least the hammering sound generating and collecting means are united into one body, is integrated as a condition measuring apparatus unit 1. This instrument contains a unit pushing means 2 which pushes the unit 1 against the surface of the concrete C with a prescribed magnitude of force, and a measuring apparatus pushing means 3 which pushes each condition measuring apparatus 11 of the unit 1 against the surface of the concrete C with a prescribed magnitude of force. Each condition measuring apparatus 11 is provided with a measuring apparatus shape tracking means 13 which perpendicularly pushes its own apparatus 11 against the surface of the concrete C to make the apparatus 11 flow the surface form of the concrete C.
