[0002] Concrete refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates; and water (which may contain admixtures and additives) are mixed in a certain proportion and the resulting cement concrete is also called ordinary concrete. It is widely used in civil engineering. In the construction process of houses, concrete pouring is now used for construction. It is not only faster but also more solid. After the concrete is poured, the thickness of the concrete needs to be measured by instruments in order to inspect the quality of the building.
[0003] Workers engaged in concrete pouring found in actual work that most measurement methods involve workers inserting steel bars into the concrete layer on site, then pulling them out, and measuring the parts of the steel bars where the concrete marks are stained. However, during the process of pulling the steel bars upward, part of the concrete will float upward due to inertia, causing the height of the stained marks to shift upward, which makes this method have large errors and cumbersome operation. For this reason, we propose a cast-in-place concrete thickness measurement device. Utility Model Content
