[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] See Figs. 1-2 As shown, a concrete floor flatness control device includes: a support assembly, a leveling ruler 10, a scraper 11, and a structural plate 12. The support assembly is provided in several groups, which are arranged in a longitudinal and transverse array. The support assembly is fixedly connected to the structural plate 12. The top of the transverse array of support assemblies is detachably fixedly connected to the leveling ruler 10, and the top of the longitudinal array of leveling rulers 10 is provided with a scraper 11 for leveling the concrete.

[0025] In this embodiment, the support assembly includes: a base 1 and a support screw 2. The base 1 is inserted and fixed to the top of the structural plate 12. The top of the base 1 is threadedly connected to the support screw 2. The top of the support screw 2 is fixedly connected to a limiting member for preventing displacement of the elevation ruler.

[0026] In this embodiment, a plurality of fixing holes 1201 are evenly provided on the structural plate 12, and the base 1 is inserted and fixed in the fixing holes 1201; the bottom end of the base 1 is conical, so that the base 1 can be smoothly inserted into the fixing holes.

[0027] In this embodiment, a nut 3 is threaded onto the support screw 2, and the support screw 2 is tightened and fixed by the nut 3.

[0028] In this embodiment, the limiting component includes: a support base 4, a slider 5, and a gripper 6. Two sliders 5 and two grippers 6 are provided. The support base 4 is fixedly connected to the top of the support screw 2. Two longitudinal grooves 401 are symmetrically opened on the front and rear sides of the top of the support base 4. Two sliders 5 are symmetrically slidably connected in the two longitudinal grooves 401. Two grippers 6 are symmetrically arranged on the top of the two sliders 5. The support base 4 is provided with an adjustment component for driving the two sliders 5 to move synchronously towards or away from each other.

[0029] The adjustment assembly includes a bearing 7, an adjusting screw 8, and a drive handle 9. The adjusting screw 8 is rotatably connected to the middle of the support base 4 via the bearing 7. Two sliders 5 are threaded through and connected to the front and rear sides of the adjusting screw 8, respectively. The threaded grooves on the front and rear sides of the adjusting screw 8 are in opposite directions. One end of the adjusting screw 8 is fixedly connected to the drive handle 9. When the elevation ruler 10 is placed at the top center of the support base 4, rotating the drive handle 9 will drive the adjusting screw 8 to rotate and simultaneously drive the two sliders 5 to move towards each other along the two longitudinal grooves 401 and clamp the elevation ruler 10 to prevent the elevation ruler 10 from shifting.

[0030] In this embodiment, the top surface of the elevation ruler 10 is flush with or higher than the top surface of the gripper 6.

[0031] In this embodiment, both the elevation ruler 10 and the scraper 11 are made of lightweight aluminum alloy, which is easy to reuse and not easily deformed; after each use, cleaning and maintenance can effectively extend the service life of the tools.

[0032] In this embodiment, the length of the scraper 11 is 6m, the distance between two adjacent longitudinal support components is 2m, and the distance between two adjacent transverse support components is 5m; in order to facilitate precise control of on-site construction.

[0033] This utility model provides a concrete floor flatness control device, which, compared with conventional concrete floor elevation and flatness control methods such as making mortar spots, uses a "grid-like" method to pre-embed support components to control concrete flatness.

[0034] The elevation ruler mentioned must be gradually removed from the concrete after construction is completed to facilitate subsequent work. When using a screed, the concrete surface needs to be leveled repeatedly.

[0035] The feature of this utility model is that it includes three construction stages. First, in the construction preparation stage, fixing holes 1201 are drilled on the structural slab surface of the planned concrete floor, and the base 1 is fixed in the fixing holes 1201 by hammering or other methods; then, the support screw 2 is screwed into the base 1, and the elevation of the support screw 5 is adjusted by using the nut 3; finally, the elevation ruler 10 is placed in the limiting member.

[0036] Next, during the concrete pouring stage, a crucial part of the construction process, the concrete is repeatedly leveled using a screed 11 to ensure its flatness.

[0037] Finally, after the concrete is poured, gradually remove the screed 11 and leveling ruler 10 from the concrete. After removing them, use the screed to level the surface 2-3 times.

[0038] During the initial setting stage of concrete, the flatness of the concrete surface should be checked immediately using an elevation ruler 10 to ensure it meets the predetermined standard. If the flatness is found to be unsatisfactory, measures should be taken immediately to adjust it. For example, if a certain area of ​​the concrete surface is too high, the excess can be gently scraped off with a screed 11; if a certain area is too low, an appropriate amount of concrete needs to be added and the surface leveled again.

[0039] Before the concrete sets completely, a final inspection and adjustment are performed to ensure the concrete floor's flatness is optimal. At this stage, the use of a level gauge (e.g., 10mm) is crucial, as it helps construction workers accurately determine if the concrete surface elevation is consistent. This method effectively controls the flatness of the concrete floor, reducing the likelihood of later repairs and rework.

[0040] During the adjustment of the support screw 2, this invention employs a high-precision nut to ensure accurate elevation adjustment of the support screw 2. This design allows for more precise elevation control of the concrete floor, contributing to the smoothness control of large-area concrete floors.

[0041] The embodiments of this invention not only improve the construction quality of concrete floors but also increase construction efficiency by simplifying the construction steps. Compared with traditional methods, this invention reduces reliance on the skills of construction workers, making the construction process more standardized and regulated. Furthermore, this invention has a simple structure, is easy to operate, and is convenient for widespread application in various construction sites.
