This utility model discloses a verticality measuring ruler for building engineering, relating to the field of measuring ruler technology. Its key technical features include a ruler body comprising a first ruler rod and a second ruler rod. The upper end of the first ruler rod and the lower end of the second ruler rod are rotatably connected via a rotating shaft. A locking mechanism is provided between the first and second ruler rods. During use, rotating the second and first ruler rods makes the ruler body vertical. During this process, under the action of a spring, a limiting tooth block is pushed to engage with a slot on the surface of the insertion plate, thus firmly connecting the first and second ruler rods together and preventing bending between them. This provides strong stability. During measurement, under the gravity of a lead block, when the wall is not vertical, the vertical gravity of the lead block causes the pointer to point to the corresponding sector scale. The verticality of the wall can then be measured using the sector scale indicated by the pointer. This method is convenient to operate and offers high accuracy.
