Apparatus for performance enhancement of blastwall structure using deformation measurement instrument

摘要

The present invention provides an explosion-proof wall performance enhancing device using a strain gauge that detects an explosive load in real time and generates a tensile force according to the displacement of the explosion-proof wall to further improve the resistance performance by causing the axial force to act on the ground on the explosion-proof wall. . According to a suitable embodiment of the present invention, the explosion-proof wall fastening hardware installed so as to be fixed to the upper portion of the explosion-proof wall; a deformation measuring sensor installed on the side of the explosion-proof wall fastening hardware to detect deformation of the explosion-proof wall due to blast pressure; a tension member for transmitting axial force having one end connected to the side of the explosion-proof wall fastening hardware and disposed in a vertical direction; an electric actuator that is fixedly disposed on the bottom of the explosion-proof wall and is connected to the other end of the tension member for transmitting axial force to generate a tensile force in the tension member for transmitting axial force when blast pressure occurs; and a signal processing control system for controlling the operation of the electric actuator by calculating the tensile force applied to the explosion-proof wall from the deformation detection signal obtained from the deformation measuring sensor when the detonation pressure occurs.
