Observation equipment for steel structure engineering inspection

Abstract

The present invention relates to the field of steel structure engineering inspection equipment, in particular to an observation equipment for steel structure engineering inspection, which includes a clamping mechanism and a marking mechanism. The clamping mechanism is placed on the ground, and a marking is installed on the upper end of the clamping mechanism. Line mechanism, the present invention adopts the design concept of the combination of limit and adjustment. The present invention can accurately control the downward distance of the stylus according to the thickness of the steel structure, so as to avoid the insufficient downward distance of the stylus and cause the coating If the layer is not completely cut through or the down distance is too large, it is easy to get stuck, which will help improve the accuracy of the test results of the coating adhesion on the surface of the steel structure.

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
