The most primitive form of the windows form from a minor change in the doorway, its role is to withstand the outdoor lighting and bad weather. Then the window is very rich material, from parchment to the goat, horns of paper sheets to the linseed oil? In fact any kind of translucent, light through the material can be used for windows. 11th century church with a large number of construction and painting Glass Applications, the role of the window as decorative art to render religious mystery. Before the end of the 17th century, "Grid Window" by the glass production constraints, are based on the outline of the corresponding lattice fan mounted into small pieces of glass on it. So this time window function is shelter from the storm 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 a pure function of the? Rather than just simple lighting, scenic and shelter role. During this period the British invented the straight edge Shaft hinge window (ie, side hang window); Dutch invented the hanging window (ie, pulling down the window), hanging ledge vertical sliding control by a pulley device. Marks " Window Hardware System "was born. Hardware System Aluminum alloy doors and windows System development goals and the role of of With Building Form and functional requirements of the continuous development of curtain walls and windows have become increasingly demanding, and in order to meet the requirements of construction, hardware system design in the role of doors and windows need to be re-thought. It looks very simple, but it is not. This requires careful planning, guidance and input a lot of energy and financial resources designed to achieve this. Hardware system development and design should have some adaptability and flexibility. In the design development process should take account of "building factor" and "human factors." Make decorative, functional, safety, convenience and comfort should meet the requirements of architectural design. For aluminum window systems development and design of the ultimate goal ---- kinds of new doors and windows forms, only if the designer had a complete and clear the minds of the design concept and to generate clear windows form. Therefore, in order to achieve this goal, designers must be traced back to the original function of the problem factors, and can be found in which some mode. Only by understanding our objectives and design criteria, and then to systems development. Therefore, doors and windows doors and windows of the system development and selection of hardware or development are closely linked and complementary. More importantly, the windows of the pressure deformation, water tightness, air tightness, thermal insulation, sound insulation resistance, internal deformation, opening and closing of the vertical load, repeatedly opening and closing of all related hardware systems related hardware system the merits of doors and windows performance, plays a decisive role, as windows and doors industry expert Professor Li Zhiyi advocated " Hardware Non-supporting role, but the doors and windows of the heart. " Door & Window Hardware System diversification Architectural design development and window systems technology, and industrial machinery and materials for 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 vigorous, Energy Systems, lighting systems, ventilation systems and window and door contacts will have a more accurate hardware features, as well as the related systems and door good adaptability. Emerged a variety of hardware systems, such as the common form of the market: outside the flat open hardware, open hardware inside the flat, tilt & turn hardware, Window Hardware in the suspension (hanging vertical transfer), in hanging Window Hardware (level rotation), hanging outside the Window Hardware, sliding hardware, outside the flat pushing hardware, introversion smooth lateral hardware, electrical hardware, intelligent electrical hardware, folding open the hardware, pulling hardware, ventilation equipment and so on. The following functions on the windows for ventilation for an analysis, we can see the prospects for the direction of door and Window Hardware and diversification. 2002 edition of the "China Eco Residential Technology Assessment Manual" request "to open doors and windows should have drafts when the indoor conditions, over 90% of indoor space should be able to achieve natural ventilation" (necessary conditions). 2001 National Housing and living environment Project By the Center for the "Healthy Housing technical points" called for "Residential living space should be natural ventilation, no ventilation and dead space", "the prevention of air pollution on human health damage, suppression of indoor air pathogens and harmful substances. We are high quality suppliers, our products such as China 2.4G Wireless Optical Mouse , USB Laptop Speaker for oversee buyer. To know more, please visits Basic Optical Mouse.
