Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a device for detecting the flatness of a building surface. Background Art

[0002] The flatness of building walls is an important indicator to measure the smoothness of wall surfaces, which directly affects the aesthetics of wall decoration and the quality of subsequent wallpaper laying and paint construction. Laser distance measuring equipment (such as infrared distance measuring sensors) is currently a commonly used flatness detection equipment. Laser distance measuring equipment is used to accurately measure the parallelism or verticality of the wall and the laser line by emitting laser lines, thereby obtaining the flatness data of the wall; however, when using laser distance measuring equipment to detect the wall, it is necessary to ensure the level of the laser distance measuring equipment. For example, the authorization publication number CN 219977358 U "A wall flatness detector for construction" provides a device to adjust the height of the self-locking universal wheel and the levelness of the bottom plate. During the adjustment process, by observing whether the hanging rope and the vertical rod overlap, it is determined whether the column is in a vertical state. When the column is vertical, the infrared distance measuring sensor is in a horizontal state. However, the device requires manual precise adjustment and observation of the vertical rod to ensure that the column is vertical, which is time-consuming and labor-intensive, and the detection efficiency is poor.
