Doors and Windows hardware future facing the challenge of diversification
It is reported, doors and windows hardware, adornment sex, functional, safety, convenient and comfortable sex all should meet the requirements of the architectural design. The most primitive form of make a change a bit from the window of the form, and its function is used to resist outdoor lighting and severe weather. The price of the window when finely machine makings is very rich, from a parchment to goat skins, ox horn chips to linen sheet-in fact any a translucent, the light can be the material can be used in through the window.
11 th century as Christ church built and a large number of coloured drawing or pattern glass, the application of the function of the window become adornment art to render the mystery religions. 17 th century ago, 'lattice window by the restriction of the glass production ", according to case the outline of fan set into small pieces of accordingly glass. So at this time of the window function just zheyu wind and prevent thieves of the invasion.
Until late 17 th century, with the progress of The Times, glass industrial production, the relationship between man and nature of change. People realize the window also finely machine manufacturers should be pure function of-and not just to have the simple daylighting, swimming, shelter role. During this period the British invented the straight edges type a casement (that is, make the same score a window); The Netherlands invented the DiaoChuang (i.e. push-up window), DiaoChuang sliding along vertical direction by a pulley equipment control. Marks' doors and windows hardware system "was born.
Along with the architectural form and the functional requirements development, of window curtain wall requirements more and more high, but in order to meet the requirements of the architecture, hardware systems technology in aluminum sliding door design of the function also needs to be rethought. This looks very simple, but that was not the case. This requires careful planning, guide the ball mill and for a lot of energy and financial resources to achieve the design purpose. Development of the system hardware design should have certain adaptability and flexibility.
The design and development should be considered in the process of building factors' and ' 'the human factor' ceramic ball mill compound fertilizer equipment, zhengzhou red star machinery factory.So Windows system development with the Windows and doors of the selection of the hardware or development is closely linked, supplement each other. More important is the window of door of wind pressure deformation, water tightness, air tightness and heat preservation sex, sound insulation sex, sex, sex deformation in opening and closing, vertical load, and repeatedly opening and closing of all related with hardware system, hardware system of the doors and Windows of the performance quality, plays a decisive role, as the door window industry experts LiZhiYi professor advocated 'hardware accessories the supporting role, but the heart of the doors and Windows ".
The development of architectural design idea and window system technology and machinery and materials in the further development of the industry, building hardware category roll crusher also from traditional simple forms to functional, specificity development. Door window will have more vitality and energy saving system, lighting, ventilation system and the system of door window contact will make hardware has more accurate functional characteristics, and with the Windows and doors every relevant system good adaptability.
Various kinds of hardware system emerged, such as at present market common form: the flat open hardware, cement production technology in flat open hardware, open within pour inside hardware, the central suspension of aluminum folding door hardware (vertical suspended turn), the central suspension of window hardware (level rotary), the suspended window hardware, push-pull hardware, the horizontal pushing hardware, NaQing smooth lateral hardware, electric hardware, intelligent electric hardware, folding open hardware and tiras hardware, ventilated take a breath device and so on.
The 2002 edition of the "Chinese ecological residence technology assessment manual" required "Windows open indoor should have the conditions when drafts, indoor more than 90% of the space should be able to realize the natural ventilation '(necessary conditions). 2001 national housing and living environment engineering center compiles "healthy residential construction technology key point of the requirement in the 'living space of the house can be natural ventilation, no ventilation blind Angle', 'should prevent air pollution on human health damage, stop the pathogen in indoor air and harmful material damage.
