自保温墙体粘贴超薄石材幕墙新技术

New Technology of Pasting Ultrathin Stone on AAC Exterior Wall

传统的干挂石材幕墙技术使用钢材作为骨架、岩棉作为保温材料,造价高,而且岩棉易吸水,降低了保温效果。采用自保温墙体粘贴超薄石材幕墙,既能体现建筑物的风格,又可以满足外墙保温节能要求。这一新技术利用自保温墙体砌块自身优良的保温性能,通过石材防护剂解决石材渗水问题,在抹灰层中埋置钢丝网保证抹灰层的整体性和基层粘贴力,创新性地在轻质墙体外侧粘贴超薄石材（5~8 mm）,配合专用保温砌筑砂浆和保温抹灰砂浆,采用小灰缝工艺进行墙体砌筑,可以有效解决石材湿贴的质量通病,达到石材幕墙的效果,而且墙体热工性能满足节能标准要求,具有广阔的应用前景。

The traditional technology of dry hanging stone curtain wall uses steel as a skeleton and rock wall as insulation materials. But this technology costs a lot and decreases the thermal insulation because the rock wall easily absorbs water. AA C curtain wall pasted ultrathin stone can reflect the style of buildings and meet the requirement of energy-saving wall insulation. The new technology uses the excellent insulation of AA C brick, solves the water seepage of stone by stone protective agent, ensures plastering layer integrity and grassroots paste by burying steel wire mesh in plastering layer, and pastes ultra-thin stone （5-8 mm） on light material wall. Considering it effectively solves the quality problems of stone curtain wall, and the curtain wall can meet the energy-saving standards with a broad application prospect.
