1 引言

背栓式石材幕墙安装,主龙骨采用槽钢,横梁用镀锌角钢,并进行热镀锌处理。用不锈钢螺栓将挂件固定于横梁上,不锈钢背栓螺栓穿过背栓铝合金挂件与石材板相连,石材板由背栓铝合金挂件承托。石材板缝内塞泡沫棒,并注石材专用耐候密封胶。要提高背栓式石材幕墙的安装质量,需了解影响背栓式石材幕墙安装的相关质量缺陷,如石材板块安装时防水处理不当;与建筑物主体结合收口时没有与土建有效配合;槽钢立柱伸缩缝设置不规范;石材板块存在天然裂纹较普遍;石材板块缺棱掉角;背栓螺栓与石材板块连接不牢固;槽钢龙骨安装时,不按规范操作没有抓好质量等。并且进一步分析哪些要因对背栓式石材幕墙安装的相关质量缺陷造成影响,这样才能采取有效的对策实施来提高背栓式石材幕墙的安装质量。
