Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a turnover adjustable concrete floor thickness controller. Background Art

[0002] At present, the main concrete slab thickness control technology disclosed is the wire drawing method. After the concrete is poured, we found that the bottom template of the slab has some large and small deviations, which directly leads to the seemingly flat slab surface being unqualified due to the influence of the bottom template. In addition, the vertical steel bars of the column may have a small deviation during construction due to the influence of external construction, which ultimately leads to adverse effects such as inaccurate elevation control lines and shaking of the wires, which directly leads to deviations in slab thickness control and cannot achieve the expected effect.

[0003] Alternatively, you can use a finished plate thickness controller to control the plate thickness. However, the plate thickness controller is more convenient to use on wooden formwork. When used on aluminum formwork, it must be nailed on the aluminum formwork, which will damage the aluminum formwork. In the composite plate system, the surface of the composite plate and the cast-in-place surface is uneven, and this controller is difficult to fix and adjust the height. In addition, the method of purchasing a finished plate thickness controller requires cash expenditure for labor. In order to save costs, the spacing on site is often too large, resulting in poor control effect. Utility Model Content
