石材干掛的背栓式與開槽式技術(shù)對比

1、背栓掛裝與開槽掛裝技術(shù)對比背栓式背栓式開槽式開槽式采用背栓連接，結(jié)構(gòu)有變形能力化學(xué)膠粘固定，結(jié)構(gòu)沒有變形能力板材獨(dú)立受力板材相互疊加，應(yīng)力集中導(dǎo)致槽口開裂背栓采用不銹鋼316材質(zhì)，質(zhì)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(diào)節(jié)功能，施工安裝方便實(shí)際施工中為調(diào)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(xué)膠粘固定化學(xué)膠粘固定/adhesion fasten一維調(diào)節(jié)一維調(diào)節(jié)/o
