Concrete fire damage depth measuring device with multi aligned array senser

摘要

The present invention provides a concrete fire damage depth measuring device having multi aligned array sensors in order to move an impact load generator to a preset position, easily adjust contact pressure between a shock wave sensor and concrete to be measured, and rapidly measure the concrete fire damage depth over an entire measurement area through the shock wave sensor arranged in a multi-row on a sensor array plate. The concrete fire damage depth measuring device having multi aligned array sensors of the present invention includes: a measurement table; a plurality of table supporting legs for horizontally positioning the measurement table at a predetermined height from a concrete structure; a spring housing positioned at a center of the measurement table and screw-coupled to be vertically movable; a sensor array plate positioned below the measurement table; a plurality of shock wave sensors arranged longitudinally and transversely on the sensor array plate; a sensor array plate pressing spring inserted into the spring housing to press down the sensor array plate; a sensor array plate connecting rod having one end inserted into the spring housing and the other end connected to the sensor array plate to transmit the pressing force of the sensor array plate pressing spring to the sensor array plate; a shock load generator transferring stand mounted at both ends of the measurement table to be transferred, and positioned on one of longitudinal grids or transverse grids in which the shock wave sensor is located; and a shock load generator fixed and installed to the shock load generator transferring stand to hit the concrete structure.
