外挂石材幕墙施工技术

Construction technology for stone curtain walls

宁夏大学教学综合楼外挂石材幕墙施工时,用植筋法进行外挂石材幕墙埋件后补.为了确保工程质量和装修效果,对石材幕墙所用材料及施工工艺进行了优化.选用的关键材料热镀锌主龙骨、次龙骨均在宁夏青铜峡铝厂的镀锌车间加工,镀锌层厚δ≥45μm;不锈钢挂件为日本的304板材,采用亚弧焊;结构胶为上海产的云石胶,密封胶为美国道康宁的硅酮树脂胶;石材保护剂为法国的PELICOAT.主要施工工序中建筑物的外轮廓测量、后植埋件、外挂板的施工等,严格按照工艺和石材幕墙技术规范进行施工,保证了幕墙的施工质量.

The main structure of the above building had been completed while the stone curtain walls were applied in construction. No patch boards were anchored in advance,and all of the patch boards were anchored after the construction of the main structure. To guarantee the quality and the performance of the building,the technology and the key materials were optimized as follows:primary and secondary zinc plating skeletal frames were all produced in Qingtongxia Aluminium Factory in Ningxia and the thickness was no less than 45μm;the stainless steel boards were No.304 steel plate made in Japan,adopting the inferior arc welding;the structural glazing sealant was the injection epoxy adhesive made in shanghai;gasket cement was silicone resin gum of DOCONIN made in U.S.A.;the stone material protecting agent was PELLCOAT made in France.The key procedure including the survey of the building sketch,post patch boards,and the construction of slate was carried on strictly in accordance with the construction technology and the technical code for stone curtain walls engineering so as to guarantee the quality of the curtain walls and accumulate some experience.
