步骤五、30mm厚无机纤维真空保温板(5)施工;
无机纤维真空保温板非标准尺寸和局部不规则处可用切割机现场切割;墙面边角处使用的保温板材最小尺寸应大于200m,将胶粘剂采取条粘法涂抹在保温板粘贴面,涂抹厚度以使胶粘剂经粘贴挤压后厚度约为3-5mm为宜,保温板有效粘结面积应不小于90%,保温板粘贴时应轻揉、均匀挤压密实,并用2m靠尺及橡皮锤对板进行调整;板与板之间要挤紧,板间接缝处侧面挤出的胶粘剂应及时清理干净,无机纤维真空保温板粘贴宜分段自下而上沿水平方向横向铺贴,上下两排无机纤维真空保温板宜竖向错缝1/2板长,局部最小错缝不得小于200mm,在墙体转角处,无机纤维真空保温板端部应垂直交错互锁,并保证转角顺直;
步骤六、填补缝隙、局部腻子(6)施工;
步骤七、专用膨胀螺栓固定;
膨胀螺栓安装的数量每平方米不少于8个,膨胀螺栓的安装位置及在基层上的有效锚固深度应满足条件:对于普通混凝土基层墙体,螺栓有效锚固深度大于等于25mm,单个螺栓抗拉承载力标准值大于等于0.60KN,对于多孔砖砌体基层墙体,螺栓有效锚固深度大于等于50mm,单个螺栓抗拉承载力标准值大于等于0.40KN;螺栓距无机纤维真空保温板边缘不应小于60mm,在胶粘剂终凝后先安装占总量约50%膨胀螺栓,待铺设耐碱网格布后再安装其余50%膨胀螺栓,螺栓应按梅花状进行布设,混凝土墙体、加气混凝土砌块墙采用普通的敲击式螺栓,对空心砖、多孔砖墙应采用摩擦和机械锁定承载螺栓,螺栓的最低安装温度应为0℃;
