Technical Field

The invention relates to the field of building decoration, in particular to a ground anti-cracking construction method.

Background

After the existing cement mortar for building ground is leveled, in the hydration and drying process, the moisture in the cement is easy to evaporate too fast due to overheating of weather or large wind, so that the cement mortar is dried, cracked and pulverized due to water shortage when being solidified, the ground can generate a lot of cracks, and as time goes on, partial cracks can be continuously expanded, thereby not only affecting the overall appearance, but also having the hidden danger of water seepage and affecting the overall quality of the building.

In view of the above, it is necessary to provide a ground crack-preventing construction method capable of effectively preventing ground cracks from occurring to solve the above-mentioned drawbacks.

Disclosure of Invention

The invention aims to solve the technical problem of providing a ground anti-cracking construction method which can effectively avoid ground cracks.

In order to solve the technical problem, the invention provides a ground anti-cracking construction method, which comprises the following steps:

leveling the ground base layer by adopting cement mortar to form a leveling layer;

after leveling, sprinkling water to the leveling layer within 12-24 hours, and covering a layer of film on the surface of the leveling layer to reduce water evaporation;

and uncovering the film after the cement mortar is solidified.

The further technical scheme is as follows: after a layer of film is covered on the surface of the leveling layer, the method further comprises the following steps:

after 3 days, the film is turned over, water is sprayed on the leveling layer, and the film is continuously covered after the water is sprayed.

The further technical scheme is as follows: adopt cement mortar to make level the formation screed-coat to ground basic unit, specifically include:

mixing cement and sand with water according to the proportion of 1:3 to form cement mortar, pouring the cement mortar on a ground base layer, and scraping the cement mortar by using a 2 m guiding rule to form a leveling layer.

The further technical scheme is as follows: before adopting cement mortar to make level the formation screed-coat to ground basic unit, still include:

the ground substrate is cleaned to ensure that the substrate is dust-free.

Compared with the prior art, the invention adopts the cement mortar to level the ground base layer, then sprinkles water on the leveling layer to fully wet the cement mortar, covers a layer of film on the surface of the leveling layer to ensure that the water is not easy to evaporate, and ensures that the cement has enough time to solidify, thereby effectively preventing the quality problems of cracking, sand blasting and the like of the later cement mortar layer caused by too fast water evaporation after the cement mortar is leveled, and further effectively avoiding the generation of ground cracks.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood by those skilled in the art, the present invention is further described with reference to the following embodiments.

The invention provides a ground anti-cracking construction method, which is used for effectively avoiding ground cracks, and concretely comprises the following steps:

a. and leveling the ground base layer by adopting cement mortar to form a leveling layer.

Specifically, in the step, cement and sand are mixed with water according to the proportion of 1:3 to form cement mortar, then the cement mortar is poured on the ground base layer, and the cement mortar is strickled by a 2-meter guiding rule to form the leveling layer. Further, before adopting cement mortar to make level the ground basic unit and form the screed-coat, still include: the floor substrate is cleaned to ensure that the substrate is free of dust or other contaminants.

b. After leveling, sprinkling water to the leveling layer within 12-24 hours, and covering a layer of film on the surface of the leveling layer to reduce the evaporation of water.

In the step, the cement mortar can be fully wetted by sprinkling water within 12-24 hours after leveling, and the thin film is covered on the surface of the leveling layer to reduce the evaporation of water and ensure that the cement has enough time to solidify.

c. After 3 days, turning over the film, spraying water on the leveling layer, continuously covering the film after the water is sprayed, and uncovering the film after the cement mortar is solidified.

In the invention, the maintenance period of the leveling layer is 7 days, preferably, in the embodiment, the film is turned over for sprinkling again after three days of covering the film, then the film is continuously covered, cement mortar is basically solidified after 4 days, the film can be taken away from the leveling layer, and the ground foundation construction is finished. The ground anti-cracking construction method provided by the invention has the advantages that the water is sprayed on the ground leveling layer, the covering film is used for keeping the leveling layer cement mortar to be fully wet, the water evaporation is reduced, the ground crack can be effectively avoided, the operation is simple, the quality control is convenient, and the material use is convenient.

In conclusion, the ground anti-cracking construction method disclosed by the invention has the advantages that the cement mortar is adopted to level the ground base layer, then the leveling layer is sprayed with water, so that the cement mortar is fully wet, the surface of the leveling layer is covered with the thin film, the moisture is ensured not to be evaporated easily, the cement has enough time to solidify, the quality problems of cracking, sanding and the like of the cement mortar layer in the later period caused by too fast evaporation of the moisture after the cement mortar is leveled are effectively prevented, the generation of ground cracks is effectively avoided, the integral impression of the building ground is better, and the quality problems caused by ground cracking in the later period are reduced.
