The role of door and window hardware accessories are often ignored. They are regarded as a secondary and supporting role in doors and windows, which is a misunderstanding. The hardware accessories are the core parts of windows and doors.
Hardware accessories are used to tightly connect the frames and sashes of doors and windows. Doors and windows are useless without them.Without its existence, doors and windows will only become dead sashes, and lose the meaning of doors and windows. Let's analyze the effect of hardware accessories on doors and windows from the performance and functions of doors and windows:
1. The physical performance indicators of doors and windows include: wind pressure resistance, air tightness, water tightness, heat preservation, heat insulation, sound insulation, wind pressure resistance Sex.
When receiving the casement window is the wind when pressure; hardware lock point force, the lock should be multi-dot form. The more locking points, the smaller the force applied by each locking point to the middle leg, and the smaller the relative deflection of the 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 multiple locking points should be adopted. The more locking points, the smaller the force applied by each locking point to the middle leg, and the smaller the relative deflection of the deformation.
When the outer casement window is subjected to positive wind pressure: the frame is stressed.
Above all, one of most important performance of doors and windows, the wind pressure resistance, is determined on the number, design and quality of hardware accessories.Similarly, airtightness, water tightness, heat preservation, heat insulation, and sound insulation are all involved in the sealing property of doors and windows, depending on hardware accessories.
Hardware fitting lock points and lock seats are distributed around the entire door and window. When the doors and windows are locked, the lock points and the lock seat are firmly buckled together and cooperate with the hinge or sliding brace to generate a strong sealing pressing force and elastically deform the sealing strip, thereby ensuring the sealing of doors and windows. Similarly, 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, and their energy consumption accounts for more than half of the building's energy consumption. It is the top priority of building energy conservation. The energy-saving issues of doors and windows, namely heat preservation and heat insulation, should be fully considered in the design. Without multi-point lock hardware accessories, no matter what material the doors and windows are used, their heat preservation and heat insulation will be not satisfying.
3. The anti-theft performance of doors and windows is also the most concerned issue. The anti-theft performance of hardware accessories, especially in the development of intelligent anti-theft doors and windows components, plays an important role.
4. There are different types of doors and windows with a variety of shapes and structural forms. The various functions of them all depend on the configuration of the hardware accessories.
In sum, hardware accessories are the "heart" of door and window accessories.
