Description

Technical Field

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

[0002] The surface flatness of curved structures 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 with formwork, and the concrete materials are poured into the inner cavity of the formwork to ensure that the concrete materials do not leak out. During or after the coagulation of concrete materials, 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 curved 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 sandpaper to rub the entire surface of the concrete curved structure. The position with obvious friction marks is the protrusion, and 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
