Background

In the construction of building engineering, more than 90% of the construction of building ground and outer wall enclosure structure plastering layers adopts manual operation (large-area and large-bay factory buildings and underground garage ground are generally leveled by adopting a mechanical leveling machine). And repeatedly pressing and smearing the concrete surface by using a spatula until the surface flatness requirement required by the engineering is met. In order to improve the flatness of the floor and the wall, a laser leveling instrument is generally used for assisting construction. During construction, the reference surface is determined, the leveling laser line emitted by the laser leveling instrument is aligned with the reference surface, and then the trowel is used for repeatedly pressing and plastering on the concrete surface. Ideally, the floor surface (wall surface) is required to be flush with the leveling laser line. However, once the floor surface is level with the leveling laser line, the floor surface may block the leveling laser line, so that leveling by the leveling laser line cannot be performed. Generally, a distance is reserved between the floor surface and the leveling laser line, the distances of all points of the floor surface need to be kept consistent during construction, and the more consistent the distance, the higher the flatness of the floor surface. This distance is controlled manually and therefore requires a high level of skill. The skills of workers are uneven, the workers are difficult to maintain a high-level construction state for a long time, and the flatness qualification rate of the floor and the wall surface is low. At present, the qualification rate of floor surface flatness is less than 80%, the maximum deviation value exceeds the standard requirement by more than 2 times, the later-stage floor surface cement mortar leveling layer needs to be increased in thickness, the self weight of the floor surface structure must be increased, engineering materials are wasted, and the engineering cost is improved. The qualified rate of the flatness of the wall surface is less than 80%, the maximum deviation value exceeds the standard requirement by more than 1.5 times, the thickness of the adhesive layer of the exterior wall coating layer or the veneer material is increased, the self weight of the structure is increased, the engineering material is wasted, the construction cost is improved, and the impression effect is influenced.
