Improved super-flat floor construction process

Abstract

An improved super-flat floor construction process comprises the steps that (1) a combined type formwork is mounted; (2) a flaky force transmission piece system is mounted; (3) an embedded type metal force transmission rod and force transmission piece system is mounted; (4) a floor is flattened, specifically, scraping-flattening is conducted through a high-flatness invar floating ruler; (5) concrete is cured; (6) a liquid curing agent is constructed; and (7) embedded type metal force transmission rod construction joints are treated. The elevations at the construction joints of the formwork are convenient to adjust precisely through matching of a level gauge, and the steel formwork is fixed through split screws when reinforced without the need of welding and perforating, so that integrity is good; and cracking of concrete edge corners at the construction joints and settlement slab-staggering on the two sides of the construction joints can be prevented, damage to the ground due to using of equipment is reduced, and the high cost brought by floor maintenance is reduced.

Description

Technical field [0001] The invention relates to a floor construction process, in particular to an improved ultra-flat floor construction process. Background technique [0002] The flatness and levelness requirements of the floors used in logistics warehousing, cargo distribution centers and other places are extremely high. The ordinary concrete floor construction technology simply cannot meet the extremely high flatness and levelness requirements, and there is no levelness standard in the national standards. Ordinary formwork cannot guarantee that the upper surface of the formwork is flat. Two adjacent concrete slabs will settle and dislocation. During use, the concrete edges and corners will be broken due to mechanical walking, concrete shrinkage and irregular gaps. The invention aims to control the construction quality of the super-flat floor by improving the template, the force transmission rod, etc., and realize the requirements of flatness and levelness of the floor.

Problems solved by technology

[0002] The flatness and levelness of the floor used in logistics warehousing, cargo distribution centers and other places are extremely high. The ordinary concrete floor construction technology cannot meet the extremely high flatness and levelness requirements at all, and there is no levelness standard in the national standard. Ordinary formwork cannot guarantee that the upper surface of the formwork is flat, and two adjacent concrete slabs will have settlement and misalignment. During use, mechanical walking will cause cracks at the corners of the concrete, shrinkage of the concrete and irregular gaps, etc.
