The windows of the most primitive form of the openings from the slightest change in form, their function is used to withstand the outdoor lighting and bad weather. At this time the windows are very rich in material, from the parchment to the goat, horns of paper sheets to flaxseed oil - in fact any kind of translucent light through the material can be used for windows. As the 11th century church in the construction and application of a large number of stained glass windows of the role of a decorative arts to render religious mystery. Before the end of the 17th century, "Grid Window" under glass production constraints, are based on the contours of the corresponding grid fan mounted into small pieces of glass on it. So, at this time the windows function is sheltered and to prevent thieves invasion. Until the late 17th century, with the progress of the times, glass industrial production, the relationship between man and nature changes. It should also be aware that the window is purely functional - and not just a simple lighting, scenic, covered the role of wind and rain. During this period the British invented the straight edge hinge-type vertical window (ie, side-hinged window); the Dutch invented the hanging window (ie, pulling up and down windows), hanging vertically sliding window edge device controlled by a pulley. Marks "window hardware system" was born.
Hardware system in the aluminum doors and windows system development goals and the role of
With the architectural forms and the functional requirements of the continuous development of the curtain wall windows and doors have become increasingly demanding, and in order to meet the requirements of the construction, hardware design, system technology in the role of doors and windows need to be re-thought. It looks very simple, but it is not true. This requires careful planning, guidance and input a lot of energy and financial resources in order to achieve this design purpose. Hardware system development and design should have a certain degree of adaptability and flexibility. In the design development process should take full account of "building factor" and the "human factor." Make decorative, functional, safety, convenience and comfort should be to meet the architectural design requirements.
Aluminum windows and doors for the ultimate goal of system development and design ---- kinds of new doors and windows forms, only when the designer produced a complete and clear the minds of the design concept and to generate clear-cut doors and windows forms. Therefore, in order to achieve this goal, the designer must be the problem dates back to the original function of factors, and where one can find some patterns. Only by understanding our objectives and design criteria before they can carry out system development. Therefore, door and window hardware door and window systems development and selection or development are closely linked and complementary. More importantly, the doors and windows of the wind pressure deformation, water tightness, air tightness, insulation, sound insulation, internal deformation, open and close nature of the vertical load, repeatedly open and close nature of all related hardware systems related hardware systems pros and cons of performance doors and windows plays a decisive role, as the windows and doors industry expert Professor Li Zhiyi the idea of a "non-supporting hardware accessories, but doors and windows of the heart."
Door and window hardware systems diversification
Architectural development of the concept and windows systems technology as well as mechanical and materials industries, further development of the scope of architectural hardware from the traditional form of simple functionality, specialized nature of the development. Doors and windows would be more vitality, energy-saving systems, lighting systems, ventilation systems and window and door hardware will make contact with a more accurate features, as well as the related systems and door good adaptability. A variety of hardware systems have emerged, such as the common form of the current market: external flat open hardware, open hardware inside the flat, which open within the inverted metal, in the hung window hardware (vertical hanging switch), in the hung window hardware (level rotation), hanging outside the window hardware, sliding hardware, external flat push hardware, introversion smooth lateral hardware, electrical hardware, intelligent electrical hardware, folding open the hardware, pulling hardware, ventilation equipment and so on.
