Among them, verticality is one of the key inspection items. Wall columns, masonry structures, and formwork all need to be inspected for verticality. There are many common inspection methods. At present, verticality detection uses an ordinary adjustable bubble ruler. Workers judge the verticality of the measured wall by observing the relative position of the magnified bubble inlaid on the aluminum alloy ruler. This requires the cooperation of several workers. At present, the measuring tool requires construction workers to stick the measuring tool to the wall of the wall to be measured many times, which leads to a large number of uses of the measuring tool. Repeated adjustments are required during measurement, affecting the efficiency of measuring the verticality of prefabricated walls. In response to the above problems, we invented a wall verticality detection device. Utility Model Content
