超低能耗建筑系统性热桥阻断技术探讨与创新

建筑围护结构热桥阻断是实现建筑节能的重要手段,是达到超低能耗建筑、近零能耗建筑、零能耗建筑的关键,其中全国各地阻断热桥的做法不尽相同,阻断技术不全面、热桥阻断不彻底现象仍有存在。该文针对严寒、寒冷地区超低能耗建筑等节能保温系统中存在保温层与结构墙体的连接锚栓或连接件等形成的热桥难以阻断等问题进行探讨研究并提出创新技术,以推动热桥阻断技术进一步发展。

Thermal bridge blocking of building envelope is an important means to realize building energy saving,and it is the key to achieve ultra-low energy consumption building,near zero energy consumption building and zero energy consumption building.The practice of blocking thermal bridge is different in different parts of the country.The phenomenon of incomplete blocking technology and incomplete thermal bridge blocking still exists.This paper discusses and studies the problems that it is difficult to block the thermal bridge formed by the connection between the thermal insulation layer and the structural wall in the energy-saving thermal insulation systems such as ultra-low energy consumption buildings in cold and cold areas,and puts forward innovative technology,in order to promote the further development of thermal bridge blocking technology.
