description The utility model relates to the technical field of verticality calibration detection, in particular to a verticality calibration detection device for constructional engineering, which comprises a first detection ruler and a second detection ruler, and a damping rotating shaft is arranged between the first detection ruler and the second detection ruler. The ends, away from the damping rotating shaft, of the front faces of the first detection ruler and the second detection ruler are provided with vertical rulers, and the positions, close to the upper end and the lower end of the handle, of the front faces of the first detection ruler and the second detection ruler are provided with negative pressure locking assemblies. The negative pressure locking assembly is composed of a negative pressure suction cup, a negative pressure sleeve, an adjusting inner sleeve, a connecting rod, a rotating hand wheel, a limiting plate, a piston and an adjusting outer sleeve, an angle adjusting assembly is connected into a first c
