Abstract

The invention discloses a construction method of a superflat floor, and relates to the technical field of floor construction. The method comprises the construction steps that sequence placing is carried out, a datum point is determined, an original ground base layer is milled and planed, and a guide rail is adjusted to an elevation face before placing; adhesion agents are smeared; the slump of concrete of each batch is detected; an imported pneumatic vibrating bridge is adopted to effectively vibrate the concrete to be compact; after vibrating, the level degree is measured again; strike-off treatment is carried out on the ground through an ultralong floating rule; hardener materials are spread in a dry mode in the initial setting process of the concrete; a hand-operation type trowelling machine is used for mud extracting work; polishing treatment is carried out multiple times; leveling work is carried out; wear-proof surface shining is carried out; a driving type trowelling machine is used for shining; the flatness and level degree of the completed ground are detected the next day, and a report is provided; expansion joints of the ground are cut within three days, and the expansion joints are generally in a span within six meters; inducing joints are filled. The method is good in construction effect, and the flatness and level degree of the floor are greatly improved.

Description

technical field [0001] The invention relates to the technical field of floor construction, in particular to a construction method for an ultra-flat floor. Background technique [0002] The floor defines the roadway area for permanent use by forklifts (ie, the restricted traffic area), and is usually classified as an "ultra-flat floor". A typical example is the application of VNA channels and high-rise shelves in the distribution center floor. This type of warehouse floor with advanced equipment must have flatness and levelness exceeding the precision, which is much higher than that of conventional floors, so that the functions of the VNA system can be fully utilized. [0003] However, the construction of the current ordinary floor cannot meet the construction of the super-flat floor, and cannot reach the required flatness and levelness, and the construction effect is relatively poor. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the...
