Description

Technical Field

[0001] The utility model relates to the technical field of engineering cost, and more specifically to a wall surface flatness detection device for construction engineering cost. Background Art

[0002] At present, the following detection methods are mostly used for the detection of wall flatness:

[0003] Manual measurement method: Use measuring tools such as a level and a plumb line to measure the wall and obtain specific deviation values. This method is simple and direct, but may be affected by human factors.

[0004] Photoelectric measurement method: Use photoelectric instruments to scan and measure the wall surface, obtain the elevation data of the wall surface through scanning, and then use professional software for analysis and evaluation. This method can quickly obtain a large amount of data and is suitable for flatness detection of large-area walls.

[0005] Laser ranging method: Use laser instruments to measure the wall, calculate the elevation data of the wall surface through the reflection and echo time difference of the laser, and then evaluate the flatness of the wall. This method has high measurement accuracy, but the equipment cost is relatively high.

[0006] Touch measurement method: A wall flatness detection instrument based on a touch sensor is used to evaluate the flatness by measuring the contact force and displacement of the wall surface. This method can intuitively reflect the unevenness of the wall surface, but it may be affected by the wall material.

[0007] However, when measuring equipment is currently used for photoelectric measurement, the measuring instrument is placed on an open ground through a tripod, and the building wall is scanned and measured by the measuring instrument. During measurement, since the measuring instrument needs to be in a horizontal state, the flatness of the setting position is required to be high. Usually, a long time of adjustment is required before the equipment is arranged, which is time-consuming and labor-intensive, affecting the efficiency and accuracy of the detection. In view of this, we propose a wall flatness detection device for construction project cost. Utility Model Content
