The role of broken aluminum door and window hardware fittings in building energy saving

In the past days, events caused by poor window quality have often occurred. For example, the floor-to-ceiling glass in a residential area of ​​a city burst into a spider web and tilted to the outside of the room. An irregular large hole is formed in the middle of the window, and a few pieces of glass are dropped by a hand. Below the window is the main passage of the community, next to a swimming pool, many people are still swimming in the pool. Another example is a plastic-steel glass window in an office building in Shenzhen, which descends from the sky. Just in the middle of the pedestrian, Ms. Zhou, her neck artery was pierced and she was unconscious. These painful cases fully demonstrate the importance of the quality of doors and windows and door and window hardware.

Due to the functional requirements of the building, the structure, the size of the space, the design style of the façade of the building, etc., the building doors and windows have various opening forms, such as inner flat opening, outer flat opening, inner opening and upper hanging, and inner opening. More than ten kinds of opening forms are suspended, and the key to making the building doors and windows have various opening forms is the door and window hardware of various structures.

The flexibility of opening and closing of building doors and windows, the difficulty of operation, and the size of operating force mainly depend on the structural design of the door and window hardware, material selection, processing and manufacturing, assembly process and assembly quality. Building doors and windows must be able to open and close, to achieve ventilation, ventilation, insulation, heat insulation, sound insulation, weatherproof and other functions, therefore, the building doors and windows are required to have wind resistance under certain wind and wind and weather conditions. Pressure performance, and the components that realize the locking function after the doors and windows are closed are the door and window hardware. For example, when the inner door and window are subjected to positive wind pressure and the outer door and window are subjected to negative wind pressure, the wind load of the door and window fan is completely transmitted to the hardware. Then the wind transmits the wind load to the door and window frame and the building structure. Therefore, the door and window hardware is the main functional component that affects the wind and pressure resistance of the building door and window.

In building energy conservation, the role of doors and windows should not be underestimated, and high-quality door and window hardware provides guarantee for high-quality doors and windows. Therefore, the role of door and window hardware in building energy conservation is gradually being taken seriously. Building experts believe that evaluating whether a building is energy efficient depends on whether resources are saved to the maximum extent throughout the life cycle of the building, including energy conservation, land saving, water conservation, and material conservation. Does it protect the environment and reduce pollution? It provides people with a healthy and efficient use of space, whether it is a harmonious and symbiotic building. Therefore, construction experts need to study the problems of each sub-area. Doors and windows as the outer protective structure of the building, its energy-saving performance directly affects the building energy-saving, and the door and window hardware as an accessory in the door and window, when it is provided for the door and window, it The advantages and disadvantages directly affect the energy-saving effect of doors and windows. Therefore, high-quality door and window hardware plays an important role in building energy conservation.
