Building wall surface plastering-free anti-crack technology

Abstract

The invention discloses a building wall surface plastering-free anti-crack technology. The technology is characterized in that different constriction processed are adopted at an internal corner and an external corner of a building, a brickwork wall surface and joints between concrete and brickwork respectively, an internal corner strip (4) and an external corner strip (5) with L-shaped cross sections are installed inside the internal corner (1) and the external corner (2) on a bottom anti-crack putty layer (3) respectively in a fillet mode, the internal corner strip and the external corner strip are coated with a surface layer leveling anti-crack putty layer (6), the brickwork wall surface built by building blocks (7) is coated with jointing anti-crack putty (11), and then the whole wall surface is sequentially coated with the bottom anti-crack putty layer (3) and the surface layer leveling anti-crack putty layer (6); the wall surface portion where the concrete (12) and the building blocks (7) are connected is directly coated with a bottom high-elasticity putty layer (13), and an anti-alkali grid cloth (14) is pressed into the bottom high-elasticity putty layer and coated with a surface high-elasticity putty layer (15). The house wall surface quality problem can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of building wall surface construction technology. Background technique [0002] At present, the delivery of houses in construction projects tends to deliver more and more well-decorated houses. During construction and delivery, the quality of the walls of the houses often leads to unqualified acceptance and difficulties in handing over the houses. Because the walls of existing buildings are all finished by manual plastering, this kind of plastering layer has many quality defects due to insufficient materials and construction techniques, such as the internal and external corners of the wall are not straight and square Or the external corner is damaged, the internal corner is cracked, the wall surface is hollow, cracked, falling off, the surface is uneven, etc., the wall surface at the joint between concrete and masonry is cracked, falling off, etc. These quality problems often cause controversy, which not onl...

Problems solved by technology

[0002] At present, construction projects are more and more inclined to deliver well-decorated houses. During construction and handover, the quality of the walls of the houses often leads to unqualified acceptance and difficulty in handing over the house.

Because the walls of existing buildings are all finished by manual plastering, this kind of plastering layer has many quality defects due to insufficient materials and construction techniques, such as the internal and external corners of the wall are not straight and square Or the external corner is damaged, the internal corner is cracked, the wall surface is hollow, cracked, falling off, the surface is uneven, etc., the wall surface at the joint between concrete and masonry is cracked, falling off, etc. These quality problems often cause controversy, which not only affects the project. Completion acceptance also affects use and perception
