铝合金门窗工程在设计、材料、施工等方面常出现一些质量通病,严重影响使用,必须引起有关方面的重视,同时要采取治理措施,以确保质量。一、铝型材厚度不够所用铝合金型材厚度偏薄。各地区风载有差异,所以设计的型材最小厚度也不一样。例如,徐州地区规定厚度为1.2mm。目前,有些图纸只注明采用铝合金门窗,却没有注明厚度。在这种情况下,建筑单位往往为了减少费用,将1.0mm(甚至0.7～0.8 The aluminum alloy door and window project often has some common problems in the design, materials, construction, etc., which seriously affect the use, and must attract the attention of relevant parties. At the same time, it must take measures to ensure quality. First, the thickness of aluminum profiles is not thin enough for aluminum alloy profiles. Wind loads vary from region to region, so the minimum thickness of the designed profile is not the same. For example, the thickness in Xuzhou is 1.2mm. At present, some drawings only indicate the use of aluminum alloy doors and windows, but did not indicate the thickness. In this case, the construction unit tends to reduce the cost by 1.0mm (even 0.7-0.8
