石材干掛的背栓式與開槽式技術對比

1、背栓掛裝與開槽掛裝技術對比背栓式背栓式開槽式開槽式采用背栓連接，結構有變形能力化學膠粘固定，結構沒有變形能力板材獨立受力板材相互疊加，應力集中導致槽口開裂背栓采用不銹鋼316材質，質保五十年。干掛膠是可降解材料，耐老化年限存在問題。具有三維調節(jié)功能，施工安裝方便實際施工中為調節(jié)板材位置可能會采用將槽口開大的方式，存在安全隱患。背栓式連接受力部位在板材背后，抗沖擊性能好開槽式在板材邊緣受力，外力作用下容易崩裂。Dry-fasten system installation technology 短槽式干掛樣例短槽式干掛樣例化學膠粘固定化學膠粘固定/adhesion fasten一維調節(jié)一維調節(jié)/o
