Abstract:

The present invention relates to a method for detecting a void in a concrete composite member covered with a steel plate using a thermal image, and a method for managing the construction of a concrete composite member covered with a steel plate by applying same. The method for detecting a void inside a concrete composite member covered with a steel plate, according to the present invention, comprises: a first step for setting a reference temperature difference which is a criterion for determining the presence of a void, wherein the reference temperature difference is set to be, in accordance with an on-site temperature and a concrete pouring temperature, the difference in temperature between a non-void and a void inside a concrete composite member covered with a steel plate; a second step for measuring the on-site temperature and the concrete pouring temperature prior to the construction of the concrete composite member covered with the steel plate, and extracting, from the reference temperature difference set in the first step, a reference temperature difference corresponding to the measured on-site temperature and concrete pouring temperature; and a third step for, during the construction of the concrete composite member covered with the steel plate, measuring, by means of a thermal image, the steel plate surface temperature of an area where concrete is poured, and determining, to be a void, a section where the difference between the measured steel plate surface temperature and the temperature of a surrounding part thereof is equal to or greater than the reference temperature difference extracted in the second step, wherein the on-site temperature in the first and second steps is set to be the temperature of outside air at the site or the average temperature of the steel plate surface temperature measured by means of the thermal image at the site prior to pouring concrete. By means of such method, after the void is detected, the section determined to be the void is additionally compacted, and thus the void may be eliminated.
