Mechanical spraying plastering construction method

Abstract

The invention discloses a mechanical spraying plastering construction method. The method comprises the following steps that base layer treatment is carried out, base layer treatment is carried out on a to-be-constructed concrete wall body; steel wire meshes are laid, steel wire meshes are arranged at the joints of a formwork brickwork and an aerated concrete block brickwork with a concrete beam, a concrete column and a concrete wall; interface layer construction is carried out, interface mortar is sprayed to the surface of the concrete wall in a mechanical spraying mode to form an interface layer; paying off and screeding are carried out, screeding is conducted on the interface layer to form ribs; mesh hanging reinforcement treatment is conducted, specifically, gridding cloth is arranged on rib parts, internal and external corners and door and window parts of the concrete wall body; surface layer mortar is sprayed and flattened; and through two-time reinforcement treatment, it is guaranteed that hollowing and cracking of the wall cannot occur.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for mechanical spraying and plastering. Background technique [0002] Mechanical spray plastering refers to the use of large mortar pumps to directly pump the plastering mortar (cement base) from the ground to the construction floor, and then spray it on the wall automatically at high pressure and high speed to realize mechanized mortar plastering construction; the mechanical spraying plastering construction method has The following advantages: [0003] High quality: The mortar pump is used for high-pressure impact, sprayed on the wall, the mortar is uniform and dense, and the bond is firm, and it is not easy to cause hollowing, cracking and falling off, which can ensure the quality and reduce the cost of rework; It can reduce the cracking and water seepage of the outer wall, thereby reducing the later maintenance cost of the outer wall.
