With the development of the national economy, China's modern building doors and windows industry has also entered a booming era. With the continuous improvement of people's living standards, people have put forward higher requirements for the living environment. The safe, comfortable and clean living environment is increasingly favored by the public. Doors and windows are the opening parts of the building's outer protective structure. They are extremely important functional parts to resist the wind and dust, realize the physical properties of building heat, sound and light environment, and have the effect of double decoration of building facade and indoor environment. It is directly related to the safe use of buildings, comfort and energy conservation, and the improvement of people's living standards. It must have various functions such as lighting, ventilation, weatherproof, heat preservation, heat insulation, sound insulation, dustproof, insect proof, fire prevention, anti-theft, etc., in order to provide people with safe and comfortable indoor living environment; at the same time, as a building exterior wall and indoor Part of the decoration, its structural form, material texture, surface color and other appearance effects play an important role in the aesthetic coordination of the interior and exterior of the building.
However, what role does the door and window hardware play in the doors and windows? People are often misled by the "fit" of the "Accessories", which becomes a supporting role in the doors and windows in the heart, which is essentially a misunderstanding.
Hardware accessories are the key components to determine the performance of doors and windows. The design of aluminum doors and windows is firstly the architectural design of the door and window performance to meet the functional requirements of the building, to reasonably determine the performance of aluminum doors and windows and related design requirements. When designing doors and windows, it is considered from the beauty of the whole house and the area where it is resistant to wind pressure, water tightness, air tightness, heat preservation, heat insulation and sound insulation (now Beijing, Guangdong, etc.) There are regional regulations that have required the corresponding building doors and windows to meet the corresponding requirements). Imagine the physical and mechanical properties (wind resistance, water tightness, air tightness, sound insulation, heat preservation, heat insulation, etc.) and mechanical properties (opening and closing force, repeated opening and closing) of doors and windows. Hardware accessories have nothing to do with it?
The hardware accessories are the components that are responsible for closely connecting the frame of the door and window with the fan. Without it, the door and window will only become a dead fan, and the meaning of the door and window will be lost. We analyze the effects of hardware accessories on doors and windows from the performance and function of doors and windows:
1. Physical and mechanical indicators of doors and windows include: wind pressure resistance, air tightness, water tightness, heat preservation, heat insulation, sound insulation and wind pressure resistance.
When the inner casement window is subjected to positive wind pressure; the hardware lock point is stressed, so it is better to adopt multiple lock points. The more the lock points, the smaller the force of each lock point to the middle, and the relative deflection of the deformation is small.
When the inner casement window is under negative pressure: the frame is stressed.
When the outer casement window is pressed: the lock point is stressed, so it is better to use multiple lock points. The more the lock points, the smaller the force of each lock point to the middle, and the relative deflection of the deformation is small.
When the outer casement window is subjected to positive wind pressure: the frame is stressed.
The above can be seen that the effect of hardware accessories on the first performance of wind and pressure resistance of doors and windows determines the success or failure of doors and windows; likewise, the airtightness, watertightness, heat preservation, heat insulation and sound insulation are all related to the doors and windows of hardware accessories. Sealed. Hardware lock points and lock seats are distributed around the entire door and window. When the door and window are locked, the lock point and the lock seat are firmly fastened together, and cooperate with the hinge (joint) or the sliding support to provide a strong sealing and pressing force, so that the sealing strip is elastically deformed, thereby providing sufficient doors and windows. The sealing performance makes the fan and the frame integrated to greatly improve the performance of the door and window. Similarly, the door and window folding mechanical performance indicators (opening and closing force, repeated opening and closing), and other opening and closing requirements are also inseparable from the requirements of hardware accessories.
2, doors and windows are lightweight components, the use of energy consumption accounts for more than half of the building energy consumption, is the top priority of building energy conservation, in the design must fully consider the energy-saving issues of doors and windows, namely insulation and insulation. If there are no multi-point lock hardware accessories, the doors and windows do a good job, and its insulation and heat insulation can be imagined.
3. Similarly, the anti-theft performance of doors and windows is also the most concerned issue for owners. In this respect, the anti-theft performance of hardware accessories, especially in the development of intelligent security doors and windows components play an important role.
4, doors and windows have a variety of window shapes and structural forms, and the various functions of the window type all depend on the configuration of hardware accessories. Imagine, there is no hardware fittings, how to realize the function of flat opening and inner turning in the swinging and lowering hanging window? How to realize the function of pushing and pulling and folding in the folding and folding window and door? Inverted pulling, moving louver, etc., which is not by hardware Does the accessory function to achieve its unique specific function?
It can be said that hardware accessories are the "heart" of door and window accessories.
For a long time, people's understanding of door and window hardware accessories is only considered to be a secondary non-functioning thing, and the result is "disastrous." Many door and window, curtain wall companies (including some of the first-class qualifications), design institutes and owners have a greater understanding of the main role of door and window hardware accessories. As a result, in the design, the size of the grid is often too large, or the weight of the window is increased, and the configuration of the hardware is arbitrarily changed, resulting in insufficient wind pressure, watertightness and airtightness. Such examples are not uncommon. I often say: I use insulating glass, high-grade aluminum, why can't I make high-end windows? This is not worthy of hardware accessories. I have seen a famous curtain wall company with first-class qualification. In the design and construction of the real estate, only a seven-handed handle is used to lock a large-sized outer open window, and in order to save costs, no sliding hooks are used on the sliding door to directly cut the groove on the profile, which seriously damages the window type. Beautiful.
