浅析保温结构一体化墙板的外门窗安装

Analysis on External Door and Window Installation of Integrated Thermal InsulationStructure

外墙保温粘锚薄抹灰技术被多省市禁止使用后,各种保温结构一体化墙板体系应运而生。仅河北省就有钢丝网架复合保温板喷涂砂浆外墙保温体系、现浇混凝土内置保温体系、大模内置现浇混凝土复合保温板体系等多种保温结构一体化产品,目前已有实际工程应用,但在实际建造过程中,门窗洞口的热量流失最大,其外门窗洞口有不同构造,门窗安装中的热桥处理、气密性影响及受力特征就是一个专项课题需要深入研究,完善超低能耗建筑系统。

After the thin plastering technology of sticky anchor for external wall insulation was banned by many provinces and cities,various integrated wallboard systems of thermal insulation structures came into being.Hebei Province alone has several integrated thermal insulation structure products,such as steel wire mesh composite insulation board spraying mortar exterior wall insulation system,cast-in-place concrete built-in insulation system,large mold built-in cast-in-place concrete composite insulation board system,which have practical engineering applications.But in the actual construction process,the heat loss of the door and window openings is the largest,and the external door and window openings have different structures.The thermal bridge treatment in the installation of doors and windows,the impact of air tightness and the force characteristics constitute a special topic that needs in-depth research so as to improve the ultra-low energy building system.
