Accessories are not supporting role, but the heart of doors and windows

Preface:

With the increasing development of the national economy, China's modern building door and window industry has also entered a flourishing era; The continuous improvement of people's living standards has put forward higher requirements for the living environment. A safe, comfortable, and clean living environment is increasingly favored by the public.

Doors and windows are the opening parts of the building envelope structure, which are extremely important functional components for resisting wind, rain, dust and insects, and achieving physical properties such as thermal, sound, and light environments in buildings. They also have dual decorative effects on the exterior facade and indoor environment, directly related to the safety, comfort, energy efficiency, and improvement of people's living standards of the building. It must have multiple functions such as lighting, ventilation, wind and rain resistance, insulation, sound insulation, dust prevention, insect prevention, fire prevention, theft prevention, etc. in order to provide people with a safe and comfortable indoor living environment; As a part of both the exterior walls and interior decoration of buildings, its structural form, material texture, surface color, and other appearance effects play a very important role in the aesthetic coordination of the inside and outside of the building.

However, what role do door and window hardware accessories play in doors and windows? People are often misled by the word "matching" of "accessories" and become a supporting role in doors and windows in their hearts, which is actually a misunderstanding.

1、 Hardware accessories are the key components that determine the performance of doors and windows

The design of aluminum doors and windows first involves the architectural design of door and window performance, with the goal of meeting the functional requirements of the building, and reasonably determining the performance indicators and related design requirements of aluminum doors and windows; When architects design doors and windows, they consider several aspects such as the overall aesthetics of the house and its location, including wind resistance, water tightness, air tightness, insulation, heat insulation, and sound insulation; (Currently, there are regional regulations in Beijing, Guangdong and other regions that require corresponding building doors and windows to meet the requirements.)

Imagine: Which of the physical properties (wind pressure resistance, water tightness, air tightness, sound insulation, thermal insulation, etc.) and mechanical properties (opening and closing force, repeated opening and closing performance) of doors and windows are not related to the hardware accessories of doors and windows (Pago PAG)?

Hardware accessories are the components responsible for tightly connecting the frames and leaves of doors and windows; Without its existence, doors and windows can only become dead fans; It also loses the meaning of doors and windows;

Let's analyze the effect of hardware on doors and windows based on their performance and function:

1. The physical performance indicators of doors and windows include wind pressure resistance, air tightness, water tightness, insulation, thermal insulation, and sound insulation;

Wind pressure resistance:

When the inner casement window is subjected to positive wind pressure, the hardware locking point is subjected to force, so it is advisable to use a multi locking point form; The more locking points there are, the less force each locking point exerts on the center, and the relative deformation is also smaller. When the inner casement window is subjected to negative wind pressure, the frame is subjected to force; When the external casement window is subjected to negative wind pressure, the locking point is subjected to force, so it is advisable to use a multi locking point form; The more locking points there are, the less force each locking point exerts on the center, and the relative deformation is also smaller. When the external casement window is subjected to positive wind pressure, the frame is subjected to force. From the above, it can be seen that the role of hardware components in the first performance of doors and windows, wind pressure resistance, determines the success or failure of doors and windows; Similarly, airtightness, water tightness, insulation, thermal insulation, and sound insulation are all related to the sealing of doors and windows that hardware components participate in. The locking points and locks of the hardware components (Paige PAG) are distributed around the entire door and window; After the doors and windows are locked, the locking point and lock seat are firmly fastened together, and together with the hinge (hinge) or sliding brace, they generate a strong sealing and compression force, causing the sealing strip to deform elastically, thereby providing sufficient sealing performance for the doors and windows, and forming a whole with the fan and frame; It can greatly improve the performance of doors and windows. Similarly, the mechanical performance indicators of doors and windows (opening and closing force, repeated opening and closing performance) and other opening and closing requirements are also inseparable from the role of hardware components.

2. Doors and windows are lightweight components, and their energy consumption accounts for more than half of the building's energy consumption. They are of utmost importance in building energy conservation. When designing, it is necessary to fully consider the energy-saving issues of doors and windows, namely insulation and thermal insulation; If there are no more locking hardware, no matter how well the doors and windows are made, their insulation and heat resistance can be imagined.

3. Similarly, the anti-theft performance of doors and windows is also a concern for homeowners. In this regard, the anti-theft performance of hardware components, especially in the development of components for intelligent anti-theft doors and windows, plays an important role.

4. There are various types and structural forms of doors and windows; The various functions of the window type depend entirely on the configuration of hardware components. Imagine, without hardware, how can a horizontally opening and inwardly folding window achieve the function of both horizontally opening and inwardly folding? How to achieve the function of both sliding and folding in sliding folding doors and windows? Which of them, such as internal reverse sliding or movable blinds, does not achieve their unique specific functions through the use of hardware?

It can be said that hardware is the "heart" of doors and windows;

For a long time, people's understanding of door and window hardware accessories has only been regarded as a secondary and non decisive thing; The result is truly "unbearable"; Many door and window, curtain wall companies (including some with first level qualifications), design institutes, and owners have a vague understanding of the main role of door and window hardware accessories, resulting in errors in grid size during design; For example, it is not advisable to use large-sized external windows in high-rise buildings, but when it comes to practical use, there are unnecessary branches that either divide the panels too large, increase the weight of windows unnecessarily, and even make arbitrary changes to the configuration of hardware accessories, resulting in insufficient wind pressure resistance, water tightness, and air tightness; Such examples are not uncommon.

People often say: I use insulated glass and high-end aluminum, why can't I still make high-end windows? In situations like this, there is no emphasis on hardware accessories (Paige PAG). I once saw a famous curtain wall company with first-class qualifications designing and constructing a building that only used a seven handle to lock a large-sized external window; In order to save costs, there is no need to lock the hook on the sliding door, and grooves are directly milled on the profile, which seriously damages the beauty of the window shape.

2、 Door and window systems

The door and window industry is actually a standard industry chain structure. Loop by loop, forming a chain mechanism. For example, after decades of development in Europe, the door and window industry has formed a branded system industry; Without systematic doors and windows, it can be said that it is difficult to move a step forward in Europe; The door and window system has been regarded as the core competitiveness of various European door and window companies. Its value is like a brand effect (such as Haier), representing the guarantee of quality and performance, which is immeasurable;

So what is a door and window system? Doors and windows should have good physical and mechanical properties and be able to meet the testing requirements of various relevant standards; Meet various market requirements; Effective coordination and management of various supporting industries; And effective cost-effectiveness;

Major foreign hardware accessory companies such as Xuge, Aruk, and Noto have already established their own mature systems, which have been developed through years or even decades of continuous exploration and research;

Looking back at the domestic market: Many of our companies, upon seeing some superficial foreign products, assume that they can only catch a glimpse and see the whole picture. They ignore the actual situation, mechanically apply the same system and make their own systems. However, they do not conduct in-depth research on the physical and mechanical properties of the doors and windows of this system.

Practice has proven that a mature door and window system needs to go through long-term practical tests; It requires multiple repeated experiments and arguments, including design, application, summarization, modification, reapplication, and summarization;

For example, some aluminum door and window factories only consider the requirements of Party A without considering the configuration of hardware components (Paige PAG), pursuing small, light, and thin. As a result, after the profile is produced, existing hardware components cannot match it; It cannot meet the requirements of industry standards and technical regulations.

This situation indicates the consequences of a lack of coordination and corresponding system concepts.

3、 The situation in our country:

China has a vast territory that spans across tropical, temperate, and cold regions. It has both desert and coastal climates, as well as plains, mountains, and hills. The terrain is diverse and the climate is variable; In the northwest region, there is drought, less rain, and more sandstorms, which requires good airtightness of doors and windows; In coastal areas, there are frequent rains and typhoons, which requires good wind pressure resistance and water tightness of doors and windows; In southern regions, there are often high temperatures, which requires good insulation of doors and windows; In northern regions, there are often cold weather and low winds, which requires better insulation performance of doors and windows; After SARS, special attention should be paid to ventilation performance; This determines that it is impossible for China to use a single system or several single systems to unify the national window type; Since the 1990s, due to the fact that most of the standard slots imported in China are 20 European standard slots, namely Germany's A0004 standard slot, it has caused Germany's hardware components to stand out in the current Chinese market. In fact, European companies classify window types of different sizes into several types of profile groove forms based on their actual situation.

The door and window market in our country has its unique situation. From the detour of aluminum doors and windows in the 1980s, to the introduction of a large number of plastic windows in the 1990s, and the resurgence of aluminum alloy windows today, all have demonstrated the enormous potential of the Chinese market. In recent years, with the strong driving force of domestic infrastructure construction, a new economic growth point has been provided for the door and window industry. Due to technological and technological improvements, doors and windows, especially insulated aluminum and electrophoretic spray painted aluminum doors and windows, have become new growth points; The diversified development of window design in real estate communities provides an opportunity for the diversified development of door and window systems. There are a large number of doors, windows, and hardware accessory enterprises in our country, with the vast majority being small in scale, low in concentration, and outdated in equipment, still in the form of small workshops for production. Difficult to form a systematic concept; To be resolved. At present, our country urgently needs to improve the performance and manufacturing technology of doors and windows, and integrate with international standards as soon as possible; This requires strengthening the technical level of door and window hardware accessories as soon as possible; Therefore, we must improve our understanding of the concept, and raise the supporting role position of hardware accessories (Paige PAG) in the hearts of Chinese people to the important position as soon as possible; Only in this way can the performance and function of doors and windows be truly improved.

4、 The true technology lies in the system engineering that matches doors and windows

Door and window hardware accessories (Paige PAG) have both static and dynamic effects, and must meet both requirements simultaneously; This fundamentally determines the refinement of door and window technology; At many exhibitions, we see many doors and windows of famous companies, which look quite good; Electrophoretic aluminum materials, even fluorocarbon sprayed aluminum materials, equipped with hollow glass, bright colors, and diverse styles; But the opening is inflexible, the shaking is large, and the configuration is unreasonable. This is the result of not valuing hardware components (Pago PAG). So what kind of functions should real door and window hardware accessories have? In addition to meeting the physical and mechanical properties of doors and windows, the following conditions must also be met

1) Easy to operate, single point control: various opening functions are achieved by changing the position of the handle handle;

2) Standardization and serialization: enabling door and window enterprises and construction companies to install quickly;

3) Adjustable: 4) Strong load-bearing capacity:; 5) High security; 6) Widely applicable: 7) Strong applicability (high-quality specifications):

In order to ensure the quality of high-end door and window hardware, precision molds and highly automated processes are generally used for manufacturing; And the materials are mainly stainless steel, aluminum alloy, zinc alloy, and high-quality engineering plastics, while meeting the strength requirements. Some factories, in pursuit of affordability, use ordinary carbon steel for production, but within a few months, rust begins to form. Even worse, changing materials and configurations arbitrarily for only one benefit has left serious safety hazards for doors and windows. When high-precision hardware accessories are combined with high-precision profiles, it may not necessarily result in a good door and window. Combining good hardware accessories and profiles requires door and window companies to put in a lot of effort in system engineering design and production; And it can only be achieved through coordination and cooperation with various relevant parties, especially hardware accessories. Many times, we often hear people complain that doors and windows are so inflexible, just blaming hardware accessories. But other issues are ignored, such as the quality of the rubber strip and profile, the accuracy of the groove (such as the size of the groove should be the size after surface treatment), and the machining accuracy of the corner assembly. The quality of doors and windows is determined by a series of complete quality assurance systems, so when making doors and windows, it is necessary to pay attention to the systematic engineering of each production process, especially to fundamentally change the disregard for hardware accessories.

Conclusion:

Door and window hardware accessories belong to capital and technology intensive industries in developed Western countries, while China's door and window hardware industry generally has insufficient funds and weak technology, and still belongs to labor-intensive industries. The gap between China and developed countries in door and window hardware is narrowing; With the improvement of living conditions for Chinese people, the demand for door and window hardware will continue to grow, and it will also move towards high-end development. The development of door and window hardware has a vast space. People are constantly pursuing higher quality and higher taste doors and windows, which provides endless imagination space for the development of hardware. Only by continuously designing, developing, and producing high-quality and high-grade hardware according to the development direction of the market can we always push doors and windows to one peak after another.
