铝合金门窗框的安装一般在主体工程完成之后,内外装饰工程之前进行(称先安法),此种安装方法一是易碰损变形,二是易腐蚀变色,三是包膜清膜费工费料。近年来有些地区采用了“预制附框法”,由于要多增设轻钢龙骨、支撑龙骨,相应提高了工程造价,同时轻钢龙骨的制作安装必须与铝合金框高度一致(因为二者之间基本不留间隙),施工的难度比
The installation of aluminum alloy door and window frames is generally performed after the completion of the main works, before and after the interior and exterior decoration works (called the first security method), this installation method is easy to damage the deformation, the second is easy to corrosion discoloration, and the third is to cover the film to work Expensive materials. In recent years, “prefabricated frame method” has been adopted in some regions. Due to the addition of light steel keels and supporting keels, the construction cost is correspondingly increased. At the same time, the production and installation of light steel keels must be consistent with the height of the aluminum alloy frame (because the Basically without gaps), the difficulty of construction
