Description

Technical Field

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

[0002] The flatness of the surface of a 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 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 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. If there are pits on the concrete surface that exceed the specified size, it is not only unsightly, but also allows external moisture to easily penetrate through the pits, thereby corroding the internal concrete structure and eventually corroding the steel bars, causing damage. 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 Manual visual observation: if protruding parts or pits are found to exceed the regulations, they are manually marked with a marker, paint, etc. This method has a large human factor, large errors, and it is difficult to judge smaller protruding parts or pits, and the accuracy is low. When manually marking, 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 perform the detection. Generally, two people are required to operate. When performing 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 (that is, the lifted height of the lifted position of the 3m ruler) is measured to determine 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. This method cannot be used for large-scale detection. Only some detection points can be selected for measurement, and the results are not universal; it requires more manual participation, 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, 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.

[0007] ④ Manually searching for pits and grooves by touch is time-consuming and laborious, and it is difficult to identify smaller pits and grooves. Utility Model Content

By applying external force to the supporting device 1, the sliding surface 201 is moved along the plane 3 to be detected. Since there is a gap between the first detection component 4 and the plane 3 to be detected, the first detection component 4 can contact the protrusion 9 whose height is greater than or equal to the gap. When the first detection component 4 contacts the protrusion 9, the detection liquid is applied to the protrusion 9 to mark the protrusion 9, thereby realizing the detection of the protrusion 9 on the surface of the planar structure; the second detection component 5 can maintain contact with the plane 3 to be detected when moving, and the places on the plane 3 to be detected except the pits 10 will be coated with the detection liquid on the second detection component 5, and the parts that are not coated with the detection liquid are the pits 10, thereby realizing the detection of the pits 10 on the surface of the planar structure.

The second detection component 5 is located at the rear of the movement direction, and the protrusion 9 coated with the first detection liquid can be marked with the second detection liquid. In order to avoid or reduce missed detection, the same area can be detected multiple times by the plane structure surface protrusion and pit detector 100.
