建筑围护结构热桥研究现状

Research status of building envelope thermal bridge

通过对比国内外热桥研究现状,分析保温层厚度、保温材料、保温方式对热桥的影响。目前研究结果表明,诸多保温方式中,外保温效果减小热桥能耗效果最好,聚氨酯保温板的保温效果最好,窗洞口处热桥能耗采用外挂的方式优于内嵌的方式,增加保温层的厚度可以减小热桥带来的能耗,保温层厚度增加过高达不到预期结果。为提升建筑围护结构经济性与节能性,对热桥的研究至关重要。

Analyzing the effects of insulation thickness, insulating material and insulation method on thermal bridges by comparing different research situations. Present research results show that many insulating methods have the best insulation effect in domestic and foreign countries at present, and the polyurethane insulation plate is excellent in the heat insulation effect, and the outside hanging method is superior to the window method in the window opening. Increasing the thickness of the insulation layer can reduce the increased heat loss of the thermal bridge. If the thickness of the insulation layer increases too high, it can not achieve the expected results, so the research on the thickness of the thermal bridge insulation layer is very important. The optimal thickness of insulation layer is selected to achieve the economic and energy-saving effect of enclosure structure.
