DEVICE FOR REALTIME MEASURING PROCEEDING CONCRETE CRACK

摘要

The present invention relates to a device for measuring the progress of concrete cracks for safety on a real time basis installed on the cracked portions of a concrete structure. The purpose of the present invention is to measure the progress of the cracks of the concrete structure on a real time basis and enable an administrator in a remote place to diagnose the cracks and reinforce the cracks rapidly by checking the measured values on a real time basis. The device for measuring the progress of the concrete cracks for safety on a real time basis according to the present invention includes a fixing stand (10) fixated to a first concrete part (1) on one side of the cracks (3); a crack movable piece (20) with one end fixated to the fixing stand and the other end supported by a second concrete unit (2) in the other side of the cracks after crossing the cracks to slide according to the movement of the concrete structure; a sensor rail (30) installed on the second concrete unit in the other side of the cracks in a direction perpendicular to the crack movable piece; width sensors installed on the sensor rail at a predetermined intervals; a sliding sensor plate (50) joined to the center of an inclined guide groove (51) to slide the crack movable piece and successively turning on the width sensors using a switch terminal (52) while sliding in the direction perpendicular to the crack movable piece in case of the movement of the first and second concrete units due to a change in the cracks; a controller sensing a change in a contact point of the width sensors and informing the administrator in the remote plate about the progress of the cracks of the concrete structure by transmitting the sensed value to a server and a portable terminal of the administrator through a communication module; a GPS module (80) installed in the fixing stand or sensor rail and informing a geological location through satellite communication; and a power source unit (61) applying power to the width sensors and controller.
