目前,我国建筑门窗广泛采用各种钢门窗,并逐步发展铝合金门窗,以代替传统的木门窗。为适应各种建筑工程的不同要求,需要建立整套技术性能标准。这些技术性能统称为门窗物理性能,包括:抗风性能(强度)、透气性能(气密性)、防水性能(水密性)、隔音性能、隔热性能(热工性能)、透光性能、耐火性能、耐蚀性能、开闭性能等。在金属门窗物理性能中,抗风能力是门窗设计的主要依据。抗风能力的合理分级和
At present, China’s building doors and windows are widely used in various steel doors and windows, and gradually develop aluminum alloy doors and windows to replace the traditional wooden doors and windows. In order to meet the different requirements of various construction projects, it is necessary to establish a set of technical performance standards. These technical properties are collectively referred to as the physical properties of doors and windows, including: wind resistance (strength), air permeability (hermetic), waterproof (watertight), sound insulation, thermal insulation (thermal performance), light transmission, fire resistance Performance, corrosion resistance, opening and closing properties, etc. In the physical performance of metal doors and windows, wind resistance is the main basis for the design of doors and windows. The reasonable classification of wind resistance
