Construction method of passive building exterior wall external insulation system with ultra-low energy consumption
The invention provides a construction method of a passive building exterior wall external insulation system with ultra-low energy consumption. The construction method specifically comprises the following steps of standing stirred mortar; smearing the mortar on a wall surface, then uniformly pulling the adhesive mortar in a zigzag shape from bottom to top by using a zigzag trowel, and attaching vacuum insulation plates to the strip-shaped mortar; arranging polyurethane foaming and anchoring marking pieces between plate joints of the vacuum insulation plates; reinforcing external corner parts by adopting plastic corner protecting strips/nets; spraying adhesion agents on the surfaces of the vacuum insulation plates, then blade-coating insulation mortar on the surfaces of the adhesion agents, uniformly smearing first rendering coat mortar on the surface of the insulation mortar after the insulation mortar is dried, pressing an alkali-resistant glass fiber net into the rendering coat mortar, and installing an anchor bolt; smearing second rendering coat mortar when the first rendering coat mortar is slightly dry and hard till the first rendering coat mortar can be touched; and coating a facing material. According to the construction method of the passive building exterior wall external insulation system with ultra-low energy consumption, the thickness of a building insulation layer is reduced, and the vacuum insulation plates are applied to a passive house, so that the thickness is reduced, air impermeability is achieved, the insulation capacity is high, and the technical effect of ultra-low energy consumption is achieved.
本发明提供了一种被动式超低能耗建筑外墙外保温系统施工方法，具体包括以下步骤：将搅拌好的砂浆静置；将砂浆涂抹在墙面上，然后用锯齿形抹子将粘结砂浆从下至上均匀拉出锯齿形状，将真空绝热板贴在条状砂浆上；真空绝热板的板缝之间设置聚氨酯发泡与锚固标识件；阳角部位宜采用塑料护角条/网进行增强处理；在真空绝热板的表面喷涂一道界面剂后，在界面剂的表面刮涂一道保温砂浆，待保温砂浆干燥后，在其表面均匀涂抹第一道抹面胶浆，将耐碱玻纤网压入抹面胶浆中并安装锚栓；待第一道抹面胶浆稍干硬至可以触碰时，再抹第二道抹面胶浆；涂抹饰面材料。本发明提供的被动式超低能耗建筑外墙外保温系统施工方法，减少了建筑保温层的厚度，将真空绝热板应用在被动房上，不仅厚度减少，而且不透气，保温能力强，实现了超低能耗的技术效果。
