subject: Analysis Of Quality Windows And Doors Products By The Test Wind Pressure Issues - Doors, Windows, [print this page] Typhoon "Morakot" at 4:20 p.mTyphoon "Morakot" at 4:20 p.m. on the on Aug. 9 Xiapu landed in Fujian, Zhejiang approach to move northwest, facing attacks Zhejiang and Fujian provinces. As at 21:00 on the on the 9th, Zhejiang Province has 454 villages and towns in 27 counties affected 340 million people, 1,844 houses collapsed, including one death. Typhoon landed in Fujian Ningde only one city, more than 120 towns and 60 million people were affected, 453 houses collapsed and economic losses have reached 416 million yuan. Doors and windows Industry and therefore are particularly concerns what kind of doors and windows have good resistance to partial pressure of performance?
Plastic Windows wind pressure problem Plastic Application in high-rise windows and doors can Building The key issue, some believe are PVC plastic door and window profile material, the intensity ratio Steel , A lot of difference between aluminum and other metal materials, plastic doors and windows should not be used in high-rise buildings. This view is a one-sided, plastic doors and windows into the window, its profile is not just the PVC, PVC profiles rather enhanced its internal steel composition, as Steel Much better than the strength of aluminum alloy, so PVC profiles and enhance the interaction of the composition of steel with high strength plastic windows and doors can withstand considerable pressure, combined with plastic doors and windows in the profile section structural design, Profiles formulation design, doors and windows design style and material selection, production process, the installation process so the further optimization of plastic doors and windows to meet the high-rise building wind pressure aspects of the use requirements.
1, doors and windows for high-rise building wind pressure requirements of the profile section reasonable structure design, plastic doors and windows in high-rise building structure design of the cross-section profiles have the following characteristics:
1) large external wall profile General lower PVC plastic doors and windows profiles, the profile thickness is generally between 2.0 ~ 2.5mm, while the high-rise building with a wall thickness of plastic doors and windows of the PVC profiles is generally between 2.5 ~ 3.0mm, this can largely increase the profile of the cross-sectional area, leading to an increased profile of the weld strength. The same dimensions, the profile of the moment of inertia will increase a lot, raise the profile of the bending capacity.
2) a reasonable profile cavity structure
Mainly in the profile distribution within the tendon on the basis of reasonable, enhance the profile increases as the size of the chamber, while the increased use of enhanced steel profile size, increase the intensity profile into a window of, so that after the profile into the window can withstand greater pressure.
2, doors and windows for high-rise building wind pressure requirements for the appropriate sections of the main aspects of the design formula by adding some raw materials to increase the profile of the weld strength, flexural capacity to improve performance, and thus meets the requirement.
3, doors and windows for high-rise building wind pressure requirements, style scientific plastic doors and windows, selection of design
1) plastic door plastic door and window style is the main part of the design. Doors and windows beautiful and elegant style that people want, but must also meet the intensity of wind pressure requirements of plastic doors and windows. Different styles of plastic doors and windows, a great impact on their ability to wind pressure, should be designed to not only meet the requirements, but also elegant style of the form of plastic doors and windows.
2) selection of plastic door and window design is the design of plastic doors and windows in the main components, high-rise building should carefully select the right material to meet the intensity of wind pressure requirements.
A, doors and windows should be based on different connection styles to choose different materials to meet different intensity of wind pressure. High wind pressure requirements, choose bigger cross section, high strength connection material; the lower wind pressure requirements, choose smaller cross section and low strength of connection material.
B, different wind pressure should choose different profile shape and strength enhanced steel thickness. In high-rise buildings, the higher floors can choose the shape of complex, thick steel to meet the enhanced intensity of wind pressure requirements, the lower floors can choose a simple shape, the smaller the thickness of steel to meet the increased intensity of wind pressure requirements. This will not only meet the requirements, but also economical and practical. 4. Doors and windows for high-rise building wind pressure requirements, the production of plastic doors and windows, install the application process to enhance the design.
