Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a simple concrete leveling nail rake. Background Art

[0002] As we all know, construction projects are mainly reinforced concrete structures. The speed of concrete construction directly affects the progress of the entire project. When pouring beam and slab concrete, due to the large pouring volume and area, the concrete is often poured in one place, and then vibrated and other measures are taken to complete the pouring. However, after vibration, the concrete surface will still be uneven in thickness, so the concrete needs to be further spread and smoothed, otherwise it will affect the flatness, aesthetics and project quality of the concrete surface.

[0003] At present, in construction, concrete will pile up during pumping or unloading, and the concrete surface will be uneven. If its flatness and density are not enough, it will directly affect the quality of the concrete floor. It is often necessary to use a leveling device to level the concrete floor, so as to facilitate the next step of construction on the concrete floor. However, the inventor of the present invention found that it is difficult to remove foreign matter mixed in the concrete during use of the existing concrete floor leveling device, which easily leads to poor leveling effect of the concrete floor, thereby affecting the leveling quality of the concrete floor, and there are certain limitations in use.

[0004] Therefore, in view of the above-mentioned related technologies, we propose a simple concrete leveling rake. Utility Model Content
