DEVICE FOR MEASURING A DIVERGENCE WIDTH OF SCRATCHES, FRACTURES AND GAPS IN BUILDING OBJECTS

摘要

The device for measuring a divergence width of scratches, fractures and gaps in building objects consisting of an upper scaled plate (2) and a tower scaled plate (1), which have fastening holes (3 and 4) allowing rigid fixing of the upper plate (2) and the lower plate (1) to the examined element in such a way that the lower plate (1) and the upper plate (2) are fixed to this element on the opposite sides of the scratch, the fracture or the gap. These plates are partially sfided over each other. The upper plate (2) is situated over the lower plate (1) in the manner allowing their mutual displacement.
