The utility model discloses a support vertical rod verticality detection apparatus, comprising a
plumb bob assembly installed at an upper position of a support vertical rod and a detection
assembly installed at a lower position of the support vertical rod when in use, the
plumb bob assembly can be controlled to freely release or recover a
plumb bob downwards, and is provided with a calibrated
release point; the detection assembly is provided with a perpendicularity calibration point, and the
release point and the perpendicularity calibration point vertically correspond to each other in position and are equal in distance from the supporting vertical rod. According to the utility model, the rapid installation of the detection device can be ensured, the verticality of the supporting vertical rod can be rapidly measured, the detection efficiency of the verticality of the supporting vertical rod can be improved, the detection device is convenient to carry by a worker, the construction time and the labor intensity of the
construction worker are reduced, the detection device is convenient to carry by the
construction worker, and the overall construction efficiency is improved.
