Aerated brick wall plastering construction method

Abstract

The invention discloses an aerated brick wall plastering construction method. The method comprises the following steps that firstly, a wall is cleaned, crack filling is performed, and then, after the wall is showered and moistened by watering, slurry throwing and galling are performed on the wall; next, a steel wire mesh is hung at a junction part between an aerated brick and a concrete wall; then, fine cement mortar is uniformly sprayed and coated on the wall, and primary scraping and leveling is performed; before the primary solidification of the mortar of the first plastering, gridding cloth is fully hung on the whole wall; after the first plastering mortar is finally solidified, the wall is subjected to second plastering guniting; meanwhile, the wall is subjected to cleaning and polishing treatment; and finally, the wall maintenance is performed. The construction method has the advantages that the aerated brick wall is subjected to plastering construction, so that the perpendicularity and the flatness of the wall can be guaranteed; the gridding cloth is arranged between a plastering surface layer and a bottom layer, so that the tensile strength and the deformation resistance of the wall are greatly improved; the aerated brick wall can be effectively prevented from generating plastering cracks; and the construction quality of the plastering wall is improved.

Description

technical field

[0001] The invention relates to a construction method for plastering an aerated brick wall and belongs to the technical field of building construction. Background technique

[0002] Aerated brick is a new type of wall material. The raw materials of aerated brick are mainly cement, lime, sand, fly ash, etc. It is a cement concrete product with a large water-cement ratio, more cementing materials, easy to absorb water and expand, and lose water. Shrinkage, low strength, high water absorption, large shrinkage deformation, etc. Because of its energy saving, land saving, less pollution and many other advantages, aerated bricks are highly praised by my country's building energy saving, environmental protection and wall reform, and are widely used in civil high-rise buildings and industrial plants. However, due to the strong water absorption of aerated bricks, it is easy to "draft" when plastering, and it is easy to cause hollowing and cracking on the plastered wal...

Embodiment

[0014] A kind of aerated brick wall plastering construction method of the present invention comprises the following construction steps:

[0015] (1) Base treatment: first clean up the loose matter, gray layer and dirt on the wall, and use dry hard cement mortar to fill the pits and cracks on the wall, and then use white latex aqueous solution to water the wall Finally, shake the pulp on the wall and brush it, which is convenient for the follow-up

[0016] (2) Hanging steel wire mesh: hang the steel wire mesh at the junction between the aerated brick wall and the concrete wall. The width of the steel wire mesh is 200-300mm. at the junction between concrete walls;

[0017] (3) The first plastering: use cement fine mortar to evenly spray on the wall, the spray thickness is 3-5mm, and then use a ruler and a trowel to initially scrape and level the wall;

[0018] (4) The second plastering: Before the initial setting of the first plastering mortar, hang the mesh cloth on the entir...
