铝合金及塑料钢门窗自问世以来,就以其特有的质轻、色美、性能好、耐腐蚀、易生产和加工,且越来越受着用户的青睐。但是,它在使用中出现的推拉滑脱问题,却长期以来困扰着人们。 为了解决这一建筑上的通病,建筑师及门窗生产厂家也曾作过多方努力。如将窗扇尽量做得长一些,或将外窗扇固定,或在窗框上槽再安装一顶条等等,以此来防止窗扇滑脱,但效果都不尽如人意。 Since the advent of aluminum alloy and plastic steel doors and windows, it has become more and more popular with users because of its unique characteristics of light weight, beautiful color, good performance, corrosion resistance, easy production and processing. However, the problem of sliding and sliding that occurs during its use has long plagued people. In order to solve this common problem in architecture, architects and door and window manufacturers have also made excessive efforts. If the sash is made as long as possible, or the outer window sash is fixed, or a top bar is installed on the window frame, etc., in order to prevent the sash from slipping off, the effect is not satisfactory.
