Door and window hardware attaches great importance to energy-saving links, and the role of environmental protection cannot be underestimated

The prosperity of the door, window and curtain wall industry has played an important role in supporting the vigorous development of its related industries, and at the same time, it has also made a huge contribution to building energy conservation.

In building energy saving, the role of doors and windows cannot be underestimated, and high-quality door and window hardware provides a guarantee for high-quality doors and windows. Therefore, the role of door and window hardware in building energy saving is gradually being valued.

Building experts believe that to evaluate whether a building is energy-saving, it depends on whether resources are saved to the greatest extent during the whole life cycle of the building, including energy-saving, land-saving, water-saving, and material-saving, and whether it protects the environment and reduces Pollution, whether it provides people with healthy and efficient use of space, and whether it is a harmonious and symbiotic building of nature. Therefore, construction experts need to study the problems in each field. As the outer protective structure of the building, the energy-saving performance of doors and windows directly affects the energy-saving of the building, and the hardware of doors and windows is used as an accessory in the doors and windows. The pros and cons directly affect the energy-saving effect of doors and windows. Therefore, high-quality door and window hardware plays an important role in building energy-saving.

However, in the past few decades, incidents caused by poor quality windows have often occurred. For example, a floor-to-ceiling window glass in a residential area in a city burst into a spider web shape and tilted out of the room. An irregular large hole is formed in the middle of the window, and many pieces of glass will fall down with a light touch. And below the window is the main passage of the community, next to it is a swimming pool, when the incident occurred, many people were still swimming in the pool. Another example is a plastic-steel glass window in an office building in Shenzhen that fell from the sky and hit the pedestrian Ms. Zhou. Her main artery in her neck was punctured and she was unconscious on the spot. These painful cases fully illustrate that the quality of doors and windows and door and window hardware is very important.

Due to the functional requirements of the building, structural form, space size, and the design style of the building's facade, building doors and windows have a variety of opening forms, such as internal flat opening, external flat opening, internal opening and top hanging, There are more than ten kinds of opening forms such as inward opening and lower suspension, and the key to various opening forms of building doors and windows is the door and window hardware of various structures.

The flexibility of opening and closing building doors and windows, the difficulty of operation, and the size of the operating force mainly depend on the structural design, material selection, processing and manufacturing, assembly technology and assembly quality of the door and window hardware. Building doors and windows must be able to open and close to achieve functions such as ventilation, air exchange, heat preservation, heat insulation, sound insulation, and weatherproofing. Therefore, building doors and windows are required to be wind-resistant under certain conditions of strong wind and wind and rain. The door and window hardware is the component that realizes the locking function after the building doors and windows are closed. For example, when the inner opening doors and windows are subjected to positive wind pressure, and the outer opening doors and windows are subjected to negative wind pressure, the wind load on the door and window sashes is completely transmitted to the hardware. Then the hardware transmits the wind load to the door and window frames and the building structure. Therefore, the door and window hardware is the main functional component that affects the wind pressure resistance of the building doors and windows.

Because the door and window hardware and the building door and window frame, fan profile rods are installed and connected to realize the opening, closing and locking functions of the door and window sash, the scientificity of the insulation position and structure of the door and window hardware and the building door and window frame and fan profile will be improved. It directly affects the thermal insulation and energy-saving effects of building doors and windows, so when doing energy-saving design of building doors and windows, the installation structure of door and window hardware and building door and window frames, fan profile rods must be considered.

The material selection, design structure and fatigue resistance of door and window hardware directly determine the durability of building doors and windows. That is to say, door and window hardware will affect the cost of building doors and windows in the entire building design life and the effective use of resources. Savings.

Under the premise that door and window hardware has high requirements for the overall performance of the entire building, especially under the requirements of saving energy and reducing energy consumption, the continuous development and improvement of new door and window hardware systems have improved the overall performance of modern doors and windows. Comprehensive performance.

Door and window hardware organically combines the opening fan and frame of the door and window, which can improve the overall wind pressure resistance, air tightness and water tightness of the building doors and windows, thereby greatly reducing the relative deformation of the door and window frames and fans , Effectively improve the sealing performance of doors and windows, so as to achieve the best energy-saving effect.

In the specific design, in order to improve the relative position change of the door and window frame sash caused by the wear of the hardware during the long-term use of the building doors and windows, in the design, the load-bearing parts of the door and window hardware can have the adjustment function of the relative position structure. In short, door and window hardware should be made of reasonable materials, good materials, strong functionality, reasonable structure, reliable use, and long life. Together with suitable door and window profiles, make building doors and windows with excellent performance, good sealing performance, safe and practical, and let the windows fall. The incident of falling and hitting people no longer occurs, making doors and windows more energy-efficient.
