Description

Technical Field

[0001] The utility model relates to the technical field of floor slab thickness measurement, in particular to an adjustable cast-in-situ concrete floor slab thickness measurement and control device. Background Art

[0002] In the construction industry, during the main structure construction phase, controlling the floor slab thickness during concrete pouring is an important part of the main project. If the slab thickness cannot be effectively controlled during the construction process, it will have a serious impact on the quality of concrete pouring. If the deviation is too large, it will affect the normal construction of the next process, causing irreparable quality and economic losses to the project. Therefore, it is particularly important to adopt an effective slab thickness control method to ensure that the floor slab thickness is within the allowable error range. This patent provides a cast-in-place floor slab thickness measurement and control device, which uses a "three-legged" to ensure the verticality of the device and ensure effective measurement and control of the slab thickness. It adopts a combination of adjustable columns and adjustable tripods. The adjustable three-legged device ensures that it is suitable for detection and data reading of various slab thicknesses. The adjustable handle ensures the user experience of different operators. Compared with traditional detection tools, it has made great progress in both function and user experience, and has a promising future for promotion and application.

[0003] For example, Chinese patent CN202021252407.0 discloses an adjustable concrete slab thickness control device, but it does not mention how to ensure the verticality of the slab thickness control tool and the specific difference between the slab thickness deviation. Theoretically, according to existing solutions, the slab thickness can only be accurately controlled when the measuring device is perpendicular to the floor slab, and the specific difference between the slab thickness and the design value cannot be determined. To this end, the present utility model proposes an adjustable cast-in-place concrete floor slab thickness measurement and control device to solve the above problem. Utility Model Content
