Description

Building engineering quality flatness detection device
Technical Field

Background
The construction engineering mainly carries out construction on houses and buildings, and after the construction on the houses and the buildings is completed, quality detection is needed, wherein the detection on the flatness in the houses is included, and the flatness condition of indoor surfaces is fully detected. Flatness refers to the deviation of the height of macroscopic irregularities of a substrate from an ideal plane. The tolerance band is the area between two parallel planes that are at a tolerance value. Flatness belongs to a shape error among shape and position errors.
The flatness measurement method comprises the following steps:
1. a feeler gauge measurement. The feeler gauge is mainly used for measuring gap spacing, and only rough measurement can be carried out on flatness measurement. Before the feeler gauge is used, dirt and dust on the feeler gauge and a workpiece must be removed. When in use, one or more pieces can be overlapped and inserted into the gap, so that the user can feel the stagnation slightly. The action is light during measurement, and hard insertion is not allowed. Because the precision is not high, the detection efficiency is low, the result is not comprehensive enough, and only the edge of the part can be detected.
2. Liquid plane method. The liquid level method uses a liquid level as a measurement reference plane, the liquid level is formed by the liquid level in a 'communicating tank', and then the measurement is performed by a sensor. Based on the working principle of the communicating vessel, the measuring device is suitable for measuring the flatness of a large continuous or discontinuous plane, but has long measuring time and sensitivity to temperature, and is only suitable for planes with lower measuring precision.
3. And (5) performing a meter-hitting measurement method. The surface-beating measuring method is to put the measured part and micrometer on a standard flat plate, take the standard flat plate as a measuring reference plane, and measure the measured part and micrometer point by point along the actual surface or along several straight directions.
With respect to the related art in the above, the inventors consider that there are the following drawbacks: in the measuring process, multi-point measurement is needed to reduce the influence of errors on the generation of measuring results, so that the staff needs to measure at the same point or at multiple points, and the workload of the staff is high.
