Abstract

The invention relates to a device and method for detecting deviation of flatness and verticality of a wall surface. The device comprises a horizontal plate, leveling knobs, a leveling bubble, a sector-shaped laser emitter, a one word line laser, and a scale, wherein several leveling knobs are arranged at the bottom of the horizontal plate, the leveling bubble and the scale are arranged on the topof the horizontal plate, the sector-shaped laser emitter is arranged above the horizontal plate and can slide along the scale, the laser emission direction of the sector-shaped laser emitter is perpendicular to the scale direction of the scale, the one word line laser is arranged at the bottom of the horizontal plate, below the starting position of the scale, and the laser positioning line of theone word line laser is vertically downward and is in the same elevation plane as the zero scale point of the scale. The device and method can conveniently and quickly measure the absolute deviation ofthe flatness and verticality of various parts of the entire wall surface and have high measurement accuracy.

Description

technical field

[0001] The invention relates to the technical field of building engineering construction detection, in particular to a device and method for detecting wall surface flatness and verticality deviation. Background technique

[0002] In the construction of construction projects, after the construction of concrete shear walls or brick walls is completed, on-site inspection of the finished products is required. At present, the main detection method is to measure with a combination of a ruler and a feeler gauge, and this method has been used in the field for a long time. Although it can quickly detect the flatness or verticality of the wall, its measurement accuracy is poor, and it can only measure the relative distance between the measured point and the measurement reference plane, and cannot measure the absolute distance between the measured point and the design reference plane ; In addition, the traditional method of measurement cannot measure the flatness and v...
