门窗的抗风压性能取决于什么
来源: 2016-03-07 13:25:18
门窗的抗风压性能取决于门窗主受力杆件的抵抗矩,往往型材的截面越大其抵抗矩也要大些,但不完全成正比。
The wind resistance depends on the doors and Windows of door window main stress resistance moment of bar, the greater the cross section of its resistance moment is also often profile be larger, but not fully proportional.
平开窗一般型材截面较小但其主受力杆件往是拼樘料或中竖料,这些主受力杆件在设计过程之中都会相应作加强处理,所以其抗风压性能较好。济南断桥铝门窗
Casement Windows general profile cross section is small but its main force bar to liu has grown two millimeters is spelling or in vertical, the main stress bar in the design process will be corresponding enhancement processing, so the wind resistance is better.
推拉窗型材截面一般比较大,按理说其抗风压性能应该会比较好,但只要稍加深入的受力分析便知其主受力杆件往往是中扇料,同时其上下梃仅靠滑轮来承受水平方向的风荷载,故期抗风压性能一般都不够理想。
Push-pull window profile cross section is compared commonly big, arguably, the wind resistance should be better, but as long as a little further force analysis as its main force bar is often in the material, and its fluctuation Ting alone pulley to withstand the horizontal wind load, so the period of performance are generally not ideal.
门窗的水密性取决于开启部位的密封效果,平开窗一般采用胶条进行密封,而推拉窗一般采用毛条进行密封,胶条的密封效果普遍都优于毛条密封。
Open the sealing effect of the water tightness depends on window, casement Windows generally adopts sealing strip, the push-pull window generally using wool top to seal, the sealing strip general effect is better than that of wool top seal.
在气密性方面目前市面上平开窗的开启扇部位较多的采用两点锁或天地锁进行锁紧密封,其密封效果较佳。
Currently on the market in terms of air tightness casement Windows open door parts more using two lock lock or heaven and earth to lock tight seal, the sealing effect is better.
而推拉窗一般都采用勾锁或碰锁进行锁紧,其密封效果不够理想。所以说平开窗在三性能方面普遍都要比推拉窗好。这也正是大部分高档商住楼都选择使用平开窗的原因所在。
The push-pull window generally USES the hook lock or locking latch, the sealing effect is not ideal. So casement Windows in three performance is better than a push-pull window generally. This is what most upscale commerce-residence building use casement Windows.
