Description

Technical Field

[0001] The utility model relates to the technical field of door and window detection equipment, in particular to dynamic wind pressure performance detection equipment for building doors and windows. Background Art

[0002] Wind pressure performance refers to the performance of building doors and windows under wind pressure. During the gas transmission process, the pressure generated by the resistance of air flow is called wind pressure. Wind pressure performance is an important indicator for building doors and windows, which is related to the safety and stability of doors and windows in strong wind weather.

[0003] Common dynamic wind pressure performance testing equipment for building doors and windows generally installs building doors and windows in the testing port, installs a fan in the testing box, and blows gas into the surface of the building doors and windows through a high-power fan to simulate the state of the building doors and windows in strong wind weather, so as to test the dynamic wind pressure performance of the building doors and windows. However, since the wind direction in strong wind weather is uncontrollable, when the wind pressure flows from the side of the building, it will flow along the surface of the building doors and windows to generate static pressure, which will cause pressure on the surface of the building doors and windows. At the same time, the wind pressure of high-rise buildings is distributed in an inverted trapezoidal shape along the vertical direction, and the wind pressure will cause pressure on the building doors and windows in the vertical direction. After the wind pressure is blocked by the building, its wind force will also change, thereby generating dynamic pressure to cause pressure on the building doors and windows. However, it is difficult for the dynamic wind pressure performance testing equipment for building doors and windows to simulate the types of wind pressure in different directions, resulting in inaccurate dynamic wind pressure performance testing of building doors and windows.
