Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, specifically relates to a building outer wall plastering layer anti -drop structure. BACKGROUND

[0002] In building engineering, especially the plastering construction of single building ground outer wall, the hanging net slurry plastering technology has become a mainstream construction method. This technology lays the mesh cloth (i.e. hanging net) on the wall base, then uses specific slurry process to form stronger bonding force between the plastering layer and the wall base, and finally completes the plastering work. The hanging net slurry plastering technology aims to improve the durability and overall strength of the outer wall to cope with the potential impact of environmental changes (such as temperature fluctuations, humidity changes) on the wall.

[0003] However, in practical application, the hanging net slurry plastering technology also exposes some key problems. First of all, the control of construction quality is crucial. If the laying of mesh cloth is uneven, the density and uniformity of slurry are insufficient, or the proportioning of plastering materials is improper, it may cause hollowing and micro-cracks inside the plastering layer. These early defects will gradually expand in the subsequent use process with the continuous action of external environmental factors (such as wind and rain erosion, temperature change), eventually leading to the bonding failure between the plastering layer and the wall base.

[0004] Secondly, due to the use of mesh cloth in the hanging net slurry plastering technology, when the plastering layer appears hollowing or cracking, these defects often expand along the laying direction of the mesh cloth. This not only accelerates the damage speed of the plastering layer, but also makes the entire plastering layer more prone to large-area peeling. This peeling not only seriously affects the appearance and use function of the building, more importantly, it constitutes a serious safety hazard. The peeled plastering blocks may directly injure passing pedestrians or damage surrounding properties, posing a threat to people's life and property safety.

[0005] In addition, long-term hollowing and cracking phenomenon also reduces the thermal insulation performance of building envelope, increases energy consumption and shortens the service life of the building. UTILITY MODEL CONTENT
