网格布翻包技术详解:外墙保温关键施工工艺
网格布翻包是什么?/ What is Mesh Fabric Flipping?
网格布翻包是指在外墙阴阳角处,网格布搭接时,两侧的网格布各自要翻过阴阳角10cm(搭界宽度20cm),以保证在外墙角处不开裂。这项工艺是外墙保温系统中的关键环节。
Mesh fabric flipping refers to the process where at the external wall corners, both sides of the fiberglass mesh should extend 10cm beyond the corner (creating a 20cm overlap width) to prevent cracking at wall corners. This technique is crucial in exterior wall insulation systems.
网格布翻包的作用/ Purpose of Mesh Fabric Flipping
1. 增强结构稳定性:有效防止外墙阴阳角处出现开裂问题
1. Enhanced Structural Stability: Effectively prevents cracking at wall corners
2. 提高防水性能:通过完整覆盖确保墙体接缝处的防水效果
2. Improved Waterproofing: Ensures complete coverage for waterproof performance at joints
3. 延长使用寿命:减少温度变化导致的材料应力,延长保温系统寿命
3. Extended Service Life: Reduces material stress from temperature variations, prolonging insulation system lifespan
外墙保温网格布翻包处理方法/ Construction Method for Mesh Fabric Flipping
1. 阴阳角处理:两侧网格布各翻过阴阳角10cm,形成20cm的搭接宽度
1. Corner Treatment: Both sides of mesh extend 10cm beyond the corner, creating 20cm overlap
2. 伸缩缝处理:首先将泡沫板抠除,然后在外墙侧将网格布收边压边
2. Expansion Joint Treatment: First remove foam board, then secure mesh edges on exterior wall side
3. 盖板安装:在伸缩缝处用专用盖板将伸缩缝盖住,注意盖板要完全覆盖压边
3. Cover Plate Installation: Use special cover plates to seal expansion joints, ensuring complete edge coverage
专业施工建议/ Professional Construction Recommendations
1. 使用优质耐碱网格布,确保长期性能稳定
1. Use high-quality alkali-resistant fiberglass mesh for long-term stability
2. 搭接处应使用专用粘结剂充分浸润
2. Fully saturate overlap areas with specialized adhesive
3. 施工时注意环境温度,避免在极端天气条件下作业
3. Monitor ambient temperature, avoid construction in extreme weather
