摘　　要：常规的高层建筑外墙节能保温技术中,对热桥冷凝问题的处理,仅以外墙保温层的厚度进行传热的改善,导致保温层失效,起不到保温作用。因此,提出基于泡沫塑料混凝土高层建筑外墙节能保温技术。首先对高层建筑外墙保温材料进行确定,选择泡沫塑料作为保温层中的一部分,然后计算外墙保温热工性能,分别对导热以及对流等现象进行分析,考虑了外墙保温的影响因素并提出解决方案,接着对外墙中出现的热桥冷凝导致的室内使用质量问题进行处理,最后精细化外墙节能构造,做到节能保温。实验中实验组保温材料的保温效能为86.7%,而对照组的保温效能为54.3%,实验结果表明所设计的节能保温技术具有一定的保温效果。In the conventional energy-saving and insulation technology for high-rise building exterior walls,the treatment of thermal bridge condensation is only based on the thickness of the exterior wall insulation layer to improve heat transfer,leading to the failure of the insulation layer and its inability to provide insulation.Therefore,the research on energy conservation and thermal insulation technology of outer wall of high-rise building based on foamed plastic concrete is proposed.In the technology,the external wall thermal insulation materials of high-rise buildings are first determined,and foamed plastics are selected as a part of the thermal insulation layer.Then the thermal performance of external wall thermal insulation is calculated,and the heat conduction and convection phenomena are analyzed respectively.The influencing factors of external wall thermal insulation are considered and solutions are proposed.Then the problems of indoor use quality caused by thermal bridge condensation in the external wall are dealt with,and finally the external wall energy-saving structure is refined,Achieve energy-saving and insulation.In the experiment,the insulation efficiency of the experimental group s insulation material was 86.7%,while the insulation efficiency of the control group was 54.3%.The experimental results can demonstrate that the designed energy-saving insulation technology has a certain insulation effect.
