石材干挂的背栓式与开槽式技术对比

1、背栓挂装与开槽挂装技术对比背栓式背栓式开槽式开槽式采用背栓连接，结构有变形能力化学胶粘固定，结构没有变形能力板材独立受力板材相互叠加，应力集中导致槽口开裂背栓采用不锈钢316材质，质保五十年。干挂胶是可降解材料，耐老化年限存在问题。具有三维调节功能，施工安装方便实际施工中为调节板材位置可能会采用将槽口开大的方式，存在安全隐患。背栓式连接受力部位在板材背后，抗冲击性能好开槽式在板材边缘受力，外力作用下容易崩裂。Dry-fasten system installation technology 短槽式干挂样例短槽式干挂样例化学胶粘固定化学胶粘固定/adhesion fasten一维调节一维调节/o
