Template verticality and lateral curvature detection tool and use method thereof

The invention relates to a template perpendicularity and lateral curvature detection tool and a use method thereof. The detection tool comprises a first detection ruler, a second detection ruler, a bubble level, a laser range finder, a laser transmitter and a laser transmitter receiving disc, wherein the first detection ruler and the second detection ruler have the same structure; the two bubble levels and the two laser range finders are respectively fixed on the first detection ruler and the second detection ruler; and the laser emitter and the laser emitter receiving disc are respectively and correspondingly arranged on the first detection ruler and the second detection ruler. The detection tool has the advantages that during detection, the length of the vertical rod can be adjusted according to the height of a wall column formwork to be detected, climbing operation of an operator is avoided, the working safety of the detector is improved, and through cooperation of the first detection ruler and the second
