Crack measuring device for safety diagnosis of facilities that can easily measure crack information

The present invention relates to a safety diagnosis crack measuring device for a facility that can easily measure crack information that can easily measure the depth of a crack located at a distance.

In general, facilities such as buildings perform safety inspection and safety diagnosis periodically or non-periodically.

Safety diagnosis and safety inspection are performed to identify and supplement structural problems of facilities. Since cracks occur first when a structural problem occurs in a facility, cracks occur and growth of cracks during safety diagnosis and safety inspection. It is most important to understand

In general, since the crack width can be observed from the outside, the growth of cracks can be observed using a cracker, etc., but since the crack depth occurs inside and it is difficult to confirm with the naked eye, equipment such as an ultrasonic measuring device is used.

The ultrasonic measuring device measures the crack depth according to the change in the wavelength of the ultrasonic wave passing through the crack, including the transmitter terminal that transmits the ultrasonic wave and the receiver terminal that receives the transmitted ultrasonic wave.

However, in order to measure the crack depth, the ultrasonic measuring device has to bring the receiver and transmitter terminals into contact with the cracked surface. There was a difficult problem in measuring the crack depth.

In order to solve this problem, in the prior art, "a device for measuring concrete strength or cracks using ultrasonic waves" of Korean Patent Publication No. 10-2210592 (published on February 2, 2021) has been disclosed.

The above-mentioned conventional crack measurement auxiliary device is a concrete strength or crack measurement auxiliary device using ultrasonic waves for measuring the strength or cracks on the side of the concrete measurement site by sending ultrasonic waves in a state in which the ultrasonic transmitting and receiving transducers are in contact with the concrete surface.

Therefore, the safety diagnosis crack measuring apparatus 100 of a facility in which crack information can be easily measured according to the embodiment of the present invention is the first terminal 210 and the second terminal ( 220) can be easily positioned to measure the crack depth, and the first terminal 210 in a form that rotates the spacing adjusting bar 150 without lowering the first terminal 210 and the second terminal 220. The precision of the measured crack depth can be improved by easily adjusting the distance between the and the second terminal 220 .

In addition, the adhesive supply unit 160 is installed so that the adhesive can be supplied to the part where the crack tip 300 is to be attached, and the crack tip 300 is installed in the tip receiving part 137 and the gap adjustment bar 150 is installed. Since the crack tip 300 is pressed and attached to the portion to which the adhesive is applied, the crack tip 300 can be easily attached to the portion where the crack is measured even from a distance.

In the above, embodiments of the present invention have been described, but the scope of the present invention is not limited thereto, and it is easily changed by those of ordinary skill in the art to which the present invention pertains from the embodiments of the present invention and recognized as equivalent. including all changes and modifications to the scope of
