Observation equipment for steel structure engineering detection

Abstract

The invention relates to the field of steel structure engineering detection equipment, in particular to observation equipment for steel structure engineering detection, which comprises a clamping and fixing mechanism and a scribing mechanism, the clamping and fixing mechanism is arranged on the ground, and the scribing mechanism is mounted at the upper end of the clamping and fixing mechanism. According to the invention, a design concept of matching limiting and adjusting is adopted; the descending distance of the scriber can be correspondingly and accurately controlled according to the thickness size of the steel structure, so that the situation that the coating layer cannot be completely cut through due to insufficient descending distance of the scriber or the movement clamping stagnation is easy to occur due to overlarge descending distance can be avoided, and the accuracy of the adhesive force detection result of the steel structure surface coating is further improved.

Description

technical field [0001] The invention relates to the field of steel structure engineering testing equipment, in particular to an observation equipment for steel structure engineering testing. Background technique [0002] With the development of science and technology, steel structures are used more and more widely in our country. From the initial large public buildings, stadiums, bridges to steel structure workshops and even civil buildings, steel structures are receiving more and more construction due to their various advantages. Units and design units of all ages, and with the widespread use of steel structures, it is very necessary and urgent to conduct regular safety assessments on existing steel structures. [0003] Steel structure detection technology includes steel structure mechanical performance detection (tension, bending, etc.), steel structure fastener mechanical performance detection (anti-slip coefficient, axial force), steel structure metallographic detection ...

AI Technical Summary

Problems solved by technology

[0004] Taking the detection of paint adhesion on the surface of steel structures as an example, the methods for detection of paint adhesion on the surface of steel structures include the circle method, the cross-cut method, and the pull-off method. Divide it into a number of squares with equal areas, then make the 3M adhesive tape fully contact with the experimental area, then quickly pull it away, and then use visual inspection or a magnifying glass to observe the scratch area to get the test result. Generally, when the adhesion reaches 1-2, it is considered as Qualified, but the following problems will occur in the process of using the cross-cut method to detect steel structure surface coatings: the control of the scratch depth of the cross-cut tool is insufficient, so that it is easy to have too deep or too shallow scratches. When the scratches are too shallow, the paint layer is not completely cut through, so that it is difficult to judge the adhesion of the complete paint layer. When the scratches are too deep, the scratching tool will cut into the steel structure, which will easily cause the scratching tool to get stuck in the subsequent movement. Hysteresis
