Back bolt is the core stress component of stone curtain wall dry hanging, which is due to:
1. The back-bolted curtain wall unit is stressed at a single point.
2. Good seismic performance
3. Installation without dust pollution
In recent years, high-rise stone curtain walls generally adopt back-bolted dry hanging.
The back bolt industry is a subdivision industry, and the technical barriers in this industry are very high. Although many small manufacturers are doing it, they don't know the technology at all, and the selection of raw materials and process control are not in place.
This poses a serious threat to the safety of buildings.
Choose a good domestic high-quality back bolt brand, because we should pay attention to the following points:
1. manufacturer's industry time: a manufacturer fully understands the technical needs of back bolt 10 years or more.
2. Manufacturer's patented technology: The understanding of product technology will produce the manufacturer's own patented technology.
3. Large-scale and long-term case inspection: 10 years of case inspection can prove its security.
4. Perfect product quality management, test report: iso900 1 seismic report, material report, etc.
5. Real popularity of the industry: There are many cooperations with first-class curtain wall companies.
