What is the role of door and window hardware accessories in doors and windows? People are often misled by the accessories and become a supporting role in doors and windows in their hearts, which is essentially a misunderstanding.
Hardware accessories are the key components that determine the performance of doors and windows. The design of aluminum doors and windows is firstly the architectural design of doors and windows performance, aiming at meeting the functional requirements of buildings, reasonably determine the performance of aluminum doors and windows and relevant design requirements. When designing the doors and windows of the building, it is considered from the beautiful and elegant appearance of the whole house and several properties such as wind pressure resistance, water tightness, air tightness, heat preservation, heat insulation, sound insulation, etc. Imagine, according to the physical properties of doors and windows (wind pressure resistance, water tightness, air tightness, sound insulation, thermal insulation, thermal insulation, etc.) and mechanical properties (opening and closing force, repeated opening and closing) which one has nothing to do with the hardware accessories of doors and windows?

hardware accessories are the components responsible for connecting the frame of doors and windows closely with the fan. Without its existence, doors and windows will only become dead fans, thus losing the meaning of doors and windows. We analyze the function of hardware accessories on doors and windows from the performance and function of doors and windows:
1. The physical performance indexes 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 under normal wind pressure; Bag hardware Lock points are stressed, so it is appropriate to use the form of multiple locking points. The more locking points are, the smaller the force that each locking point acts on the midbeam, and the smaller the relative deflection of deformation.
When the inner casement window is under negative pressure: The frame is stressed.
When the outer casement window is under pressure: the locking point is stressed, so the form of multi-locking point should be adopted. The more locking points are, the smaller the force that each locking point acts on the midbeam, and the smaller the relative deflection of deformation.
When the outer casement window is under positive wind pressure: The frame is stressed.
It can be seen from the above that the effect of hardware accessories on the first-performance wind pressure resistance of doors and windows determines the success or failure of doors and windows. Similarly, air tightness, water tightness, heat preservation, heat insulation, sound insulation is related to the door and window sealing involved in hardware accessories. Hardware accessories Lock points and lock seat are distributed around the entire door and window. When the doors and windows are locked, the lock points and lock seat are firmly locked together, and cooperate with the hinge (hinge) or dagger to generate strong sealing pressure and elastic deformation of the sealing strip, so as to provide enough sealing performance for doors and windows, and make the fan and frame form one can greatly improve the performance of doors and windows. Similarly, the mechanical performance index of doors and windows folding (opening and closing force, repeated opening and closing) and other opening and closing requirements cannot be separated from the requirements of hardware accessories.
2. Doors and windows are lightweight components, and their energy consumption accounts for more than half of the building energy consumption, which is the top priority of building energy conservation. The energy saving problems of doors and windows, namely thermal insulation and thermal insulation, should be fully considered in the design. If there is no multi-point lock hardware accessories, the doors and windows are well done, and its heat insulation and heat insulation can be imagined.
3. Similarly, the anti-theft performance of doors and windows is also the most concerned issue of the owners. In this respect, the anti-theft performance of hardware accessories, especially in the development of components of intelligent anti-theft doors and windows, plays an important role.
4. Doors and windows have various window shapes and structural forms, and various functions of window types all depend on the configuration of hardware accessories. Just imagine, without hardware accessories, how can the flat hanging window realize the function of both flat and pour inside? How to realize the function of pushing and pulling and folding in sliding and folding doors and windows? Pour Inside push and pull, activity Louver, etc., which does not rely on the function of hardware accessories to achieve its unique specific functions?
