Problems solved by technology

[0004] For the pull-through method, the accuracy of the measurement is seriously affected due to the randomness of the operators and the different levels of operating skills, especially for concrete floors with large spans.
[0005] For the dotting method, there are too few control points, and it is difficult to accurately control the flatness of the concrete floor. Especially when the floor area is large, multiple control points need to be set. Each control point needs to accurately measure the elevation, and then make it, which is time-consuming and labor-intensive; It is very difficult to protect the point, and it is easy to be damaged on site; when the thickness of the concrete floor slab is large, it is not suitable to use the point method

Abstract

The invention discloses a flatness control system for a large-span concrete floor and a use method. The flatness control system comprises a horizontal scraping ruler, a laser level meter and a corner ruler, wherein a short side of the corner ruler is fixed on the horizontal scraping ruler, and a long side of the corner ruler is vertical to the horizontal scraping ruler. The flatness control system and the use method are applicable to the construction of the large-span concrete floor. The flatness control system is simple in structure, convenient to operate and high in control precision, the number of detection and construction workers is decreased, the construction efficiency is improved, the consumption of concrete is saved, and the construction cost is lowered.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a large-span concrete floor flatness control system and a use method. Background technique [0002] At present, construction projects have higher and higher requirements for the surface flatness of concrete structures. During the construction of building structural floors, the flatness of structural floors is difficult to meet the design and specification requirements. [0003] The existing flatness control methods include the following two methods: mark the elevation control on the reserved steel bar of the wall column or pull the elevation line control, that is, the method of dotting and the method of pulling through the line. [0004] For the pull-through method, the accuracy of the measurement is seriously affected due to the randomness of the operators and the different levels of operating skills, especially for concrete floors with large spans. [0005] For the dotting me...
