Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering concrete and steel structure construction, in particular to a flatness detector for a plane structure surface. Background Art

[0002] The flatness of the surface of the plane structure can directly affect the quality of the outer tube of the product. For example, in the field of civil engineering concrete construction, the concrete materials are mainly gravel, sand, cement, water and additives. During construction, the surrounding and bottom surfaces are surrounded and compacted by templates, and the concrete materials are poured into the inner cavity of the template to ensure that the concrete materials do not leak out. During or after the solidification of the concrete material, whether the concrete surface is flat and smooth directly affects the appearance quality of the concrete. Since the material is a non-homogeneous material, it is difficult to achieve a flat and smooth surface of the concrete. If there are protruding parts on the concrete surface that exceed the regulations, it will produce obvious concave and convex appearance, which will first affect the appearance quality of the concrete. Secondly, these protruding parts will make the outer surface of the structure exceed the designed size, which will tear and break the external protective film and waterproof film, or cause friction and wear with the lifting equipment during the installation of the structure, and even scratch with the adjacent structure. During the concrete construction of the base layer, due to the uneven surface, the upper asphalt material and other flexible surface layers will be broken, causing damage to the flexible surface layer. Therefore, it is particularly important to control the flatness of the concrete surface.

[0003] Traditionally, the surface flatness detection of concrete plane structures is carried out in the following ways:

[0004] ① Observe with the naked eye manually. If the protruding parts or pits are found to exceed the regulations, they are marked manually with a marker pen, paint, etc. Observation with the naked eye is subject to large human factors and large errors. It is also difficult to judge smaller protruding parts or pits, and the accuracy is low. When marking manually, the protruding parts are generally marked by circling them inside. When trimming the protruding parts, the marks cannot be removed and need to be removed separately, which is time-consuming and laborious.

[0005] ② Use a 3m ruler for manual measurement. First select a few detection points and then conduct the detection. Generally, two people are required to operate. When conducting the detection, the 3m ruler should be close to the surface of the concrete structure. When there is a protruding part below the 3m ruler, the 3m ruler will be lifted up by the protruding part and the distance between the lifted position of the 3m ruler and the surface of the concrete structure is measured (that is, the lifted height of the lifted position of the 3m ruler is measured), and it is determined whether the measurement result exceeds the design specification requirements. The concave position below the 3m ruler corresponds to a pit, and the position of the pit can be obtained by observation. It is impossible to conduct large-scale detection, and only some detection points can be selected for measurement. The results are not universal; more manual participation is required, and the measurement method is cumbersome and inefficient; there are large human errors in the selection of detection points and manual readings.

[0006] ③ Use sandpaper to rub the entire surface of the concrete plane structure. The position with obvious friction marks is the protrusion. The position without friction marks is the pit. The sandpaper grinding method is easy to cause wear and tear on the normal structure surface, and the operation requires fine control, which is not convenient for operation. Utility Model Content
