Method for controlling thickness and flatness of concrete floor

Abstract

The invention relates to a method for controlling thickness and flatness of a concrete floor. The method comprises the following steps that a floor elevation reference control line and an auxiliary control line are marked on a white positioning plate, the white positioning plate is bound on a frame column or a shear wall reinforcing steel bar, and the floor elevation reference control line on thebound white positioning plate is consistent with a pre-marked positioning elevation corresponding to the vertical direction of the floor; a laser digital display horizontal ruler is fixed at the top of a horizontal darby slicker; when the concrete floor is subjected to last accurate flattening, the horizontal darby slicker is placed at the top of the concrete floor; and when laser light emitted bythe laser digital display horizontal ruler coincides with the elevation reference control line on the white positioning plate, the height of the bottom surface of the horizontal darby slicker is consistent with the design elevation of the upper surface of the concrete floor. The method can achieve the purposes of the economy, the convenience, the effective control of the thickness and the flatness of concrete, so that the thickness and the flatness of the poured concrete floor meet the quality standard requirements.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for controlling the thickness and flatness of a floor slab during pouring construction of a cast-in-place concrete floor slab. Background technique [0002] At present, in the construction process of cast-in-place concrete slabs, the control of the thickness and flatness of the concrete slabs generally adopts the wire hanging method and the inserting method. However, when using the hanging wire method, workers often press the wire or damage the hung control wire when they use the pump pipe of the pouring concrete pump truck to discharge materials, resulting in inaccurate or even missing control elevations; Guiding significance, but it is not very effective in controlling the flatness of the floor leveling. When checking the thickness of concrete with the plugging method, the detection is aimed at a point rather than the entire plane, so the effect of contr...

Problems solved by technology

When the quality inspection is carried out after the concrete slab is formed in the later stage, it will be found that the surface of the concrete slab is uneven and the thickness is uneven, but it cannot be changed and can only be processed later
