门窗设计的目的是提高门窗的性能质量，门窗规范和标准是门窗设计的主要依据。门窗的各种性能不是单独存在的，它们之间或多或少存在着相互促进或制约的关系，所以我们很难把性能分开来设计我们的门窗。门窗抗风压性能、气密性能、水密性能之间联系非常密切。 GB/T7106-2008《建筑外门窗气密水密抗风压性能检测及分级方法》中规定的抗风压性能、水密性能、气密性能均为可开启部分在正常关闭状态时的性能，但抗风压性能、水密性能是在风雨同时作用下的抵抗能力，在设计中也要把这种动态的变化考虑在内。正在报批的最新标准GB7106《建筑外窗抗风压性能分级及检测方法》中调整了检测装置，修改了检测顺序和检测方法，取消了气密、水密和抗风压性能的分级，但需要满足工程设计要求等等。铝合金门窗组装要按照相关技术要求和规范，也取决于加工设备质量和人员操作能力，需要控制实际操作来把控门窗质量。

The purpose of the design of doors and windows is to improve the performance and quality of doors and windows. The various properties of doors and windows do not exist alone. There are more or less mutual promotion or restriction between them, so it is difficult for us to design our doors and windows separately. The wind pressure resistance, air tightness and water tightness of doors and windows are closely related. The wind pressure resistance, water tightness and air tightness specified in GB / T7106-2008 "test and classification method for air tightness and watertight performance of building external doors and windows" are all the performance of the openable part in the normal closing state, but the wind pressure resistance performance and water tightness performance are the resistance ability under the action of wind and rain at the same time, and this dynamic change should also be taken into account in the design. The latest standard GB7106, "classification and testing methods of wind resistance performance of external windows", is being revised. The testing device has been adjusted, the detection sequence and detection methods have been modified, and the classification of air tightness, water tightness and wind resistance performance has been cancelled, but the design requirements need to be met. The assembly of aluminum alloy doors and windows should be in accordance with the relevant technical requirements and specifications, and also depends on the quality of processing equipment and personnel operation ability.

1.1、 抗风压性能

1.1 wind pressure resistance

成熟的门窗产品需要对构件做相应的强度和挠度的计算，对产品的抗风压性能有初步的判断，最终还需要做相关检测来对产品定级。

Mature door and window products need to do the corresponding strength and deflection calculation of the components, have a preliminary judgment on the wind pressure resistance performance of the products, and finally need to do relevant testing to grade the products.
