Process for constructing surface of wall body

Abstract

The invention discloses a process for construction the surface of a wall body, which can significantly reduce the construction thickness on the surface of the wall body so as to improve the effective usable area of a house. The process is characterized by comprising the following steps of: firstly, directly daubing an anti-cracking putty coating with the thickness of 2 to 3 millimeters on the surface of the wall body of which the flatness deviation is less than or equal to 4 millimeters and the vertical deviation is less than or equal to 4 millimeters; secondly, daubing a decorative putty coating on the surface of the anti-cracking putty coating, wherein the anti-cracking putty coating is prepared from the following raw materials in part by weight: 3 to 5 parts of cement, 4 to 6 parts of fine sand and 0.8 to 1.2 parts of talcpowder; each cubic meter of the anti-cracking putty coating contains 1 to 4 kilograms of polypropene micro-fibers and a proper amount of water and glue water; and the fineness modulus of the fine sand is between 2.2 and 1.6, and the average particle diameter is 0.25 to 0.35 millimeter. By adopting the construction process of the invention, the bay and the depth of the house are increased for about 30 to 38 millimeters, the effective usable area can be increased by 1 to 1.5 percent, and the consumption of building materials is reduced, so the construction cost is saved and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a wall surface construction technology. Background technique [0002] High housing prices are a serious social problem facing China at present. As we all know, the purchase area is calculated based on the building area of ​​the house. Therefore, how to increase the effective usable area of ​​the house, thereby improving the economics of purchasing a house for consumers is an important issue that house builders must consider. [0003] At present, after the building wall is built or poured, it is necessary to plaster the surface of the wall with cement mortar or mixed mortar, and then apply the decorative material layer (the decorative material layer cannot be directly applied to the brick wall, otherwise it is easy to fall off) . The thickness of the plastering layer is relatively thick, generally 18-21mm. Taking a certain project as an example, according to the current wall surface construction technology, plastering is div...

Problems solved by technology

Taking a certain project as an example, according to the current wall surface construction technology, plastering is divided into three processes: first, apply 9mm thick cement lime mortar on the wall surface to make a primer and sweep, and then apply 7mm thick cement lime mortar pad Finally, a 5mm thick cement-lime mortar should be applied to the surface and calendered. Therefore, the total thickness of the plastering layer reaches 21mm, which not only reduces the effective indoor area, but also consumes a lot of materials and increases the construction cost. Moreover, the process is complicated and the construction progress slower
