1、背栓挂装与开槽挂装技术对比背栓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短槽式干挂样例化学胶粘固定/adhesion fasten一维调节/one-dimension adjus
