The utility model relates to a building engineering detects technical field, especially relates to a straightness detection device and detection ruler for building hang down, the straightness detection device that hangs down includes counterweight, connecting rod, first fixed axle, second fixed axle, carousel and pointer, the counterweight with the connecting rod can wind first solid fixed axis rotation, and drive the carousel winds the solid fixed axis rotation of second follows the change of pointer registration can be learnt on the carousel the turned angle of connecting rod and counterweight, and then obtain the building structure's that surveys the straightness that hangs down, the sensitivity of detection is high, the precision is high. Detection ruler for building includes straightness detection device hangs down to and first casing, detection ruler for building also has detectivity height, beneficial effect that the precision is high, and first casing can prevent the straightness detection device that
