外墙外保温技术在我国已大量推广,其中的粘贴EPS板(俗称“苯板”)应用较为广泛。但有些施工人员不按规程操作,施工质量控制不严,造成了诸多质量通病的出现。在笔者亲历的一个住宅项目中,交工后冬天业主装修,发现二楼一家的地面墙角部位泛霜。经公司总工查验,确定是二楼干挂大理石与上部苯板薄抹灰墙面交接处有保温板不连续的情况,造成热桥,导致室内泛霜,装修面层结露、发霉。
Exterior wall insulation technology has been widely promoted in China, where the paste EPS board (commonly known as “benzene board ”) is widely used. However, some construction workers do not follow the rules and regulations and lax construction quality control, resulting in a lot of quality common problems appear. In my experience of a residential project, after the handover of the owners to decorate the winter and found the ground floor corner of the second floor of a pan frost. Inspected by Chief Inspector of the Company, it is determined that there is a discontinuity of the insulation board at the junction of the plastered marble on the second floor and the thin plastered wall of the upper benzene board, resulting in a thermal bridge, resulting in a pan-frost interior decoration and dew condensation on the surface.
