Building levelness detection device
Technical Field
The application relates to the field of levelness detection devices, in particular to a building levelness detection device.
Background
At present, in the construction process of buildings, the buildings need to be detected so as to ensure that the building quality of the buildings meets the detection standard. Items to be detected include verticality, wall surface flatness, levelness and the like. The levelness refers to an angle between a building and a horizontal plane or an offset between a measured plane and the horizontal plane within a certain length, for example, the levelness is three thousandth, namely, the levelness is within a measuring length range of 1000mm, and the height difference between two ends is 3 mm.
In the related art, in order to improve the detection efficiency, a bubble level meter or a level bar is generally used for measuring the levelness. When the area of the floor to be measured is large, such as a living room and a horizontal floor, a 2m long horizontal ruler can be used for measurement, and when the area of the floor to be measured is small, such as a kitchen, a toilet and the like, the 1m long horizontal ruler is used for measurement. The measurement of the levelness of the floor surface requires measurement in four corner directions with the middle of the floor surface being measured as the center. When the room is narrow, the levels with different lengths need to be switched back and forth for measurement, and the measurement process is inconvenient, time-consuming and labor-consuming.
In order to solve the problems, the chinese patent with the application number CN202020646134.1 discloses a levelness measuring device for engineering supervision, which comprises two mounting plates, a vertical rod arranged on the mounting plates, a scale arranged on the vertical rod, a ring cylinder sleeved on the vertical rod, a bump arranged on the outer side surface of the ring cylinder, a limit bolt arranged on the ring cylinder, a telescopic rod with two ends respectively connected with the two bumps in a rotating manner, and a level pipe arranged on the telescopic rod; the two mounting plates are mutually independent; the zero scale mark of the scale is arranged in the middle; one end of the limiting bolt penetrates through the annular column body along the radial direction and then is abutted against the surface of the vertical rod; the level pipe is positioned on the telescopic rod and close to the two ends.
