目前,外墙铝合金窗框的固定方法多用固定片将窗框固定在洞口中,然后用水泥砂浆把窗框四周填实。这种做法由于铝框断面较大,表面还有窗轨凹槽,所以砂浆不容易嵌填饱满,空隙率一般在40%以上,这样,不仅影响铝窗的牢固程度,更主要的是影响窗框四周的密封性能,容易产生渗水。特别是在南方,一些高层建筑遇有暴雨,雨
At present, the method for fixing the aluminum alloy window frame of the exterior wall is to use a fixing piece to fix the window frame in the hole, and then cement mortar is used to fill the frame around the hole. Due to the large section of the aluminum frame and the groove on the surface of the window, the mortar is not easy to fill and full, and the voidage is generally above 40%. This not only affects the firmness of the aluminum window, but also mainly affects the window. The sealing performance around the frame is prone to water seepage. Especially in the south, some high-rise buildings encountered heavy rain and rain.
