Six preventive measures against damage of hardware

Six preventive measures for easy damage of door and window hardware accessories

door and window hardware accessories are not only small accessories, but also more fashionable elements. Door and window hardware accessories play a huge role in doors and windows, equivalent to saving more than 50 million tons of crude oil. Although door and window hardware accessories are very small, once damaged, it will affect the overall beauty and function. Therefore, the General Administration of railways, which has just set the target of stopping the decline and recovery of traffic volume this year, should pay more attention to preventing damage and doing a good job of maintenance in advance

several measures to prevent and control the damage of hardware:

(1) the model, specification and performance of the selected hardware accessories should comply with the current national standards and relevant regulations, and match the selected plastic doors and windows

(2) for sliding windows with a width of more than 1m, or doors and windows with double glazing, double pulleys should be set, or rolling pulleys should be selected

(3) the sliding brace hinge shall be made of stainless steel instead of aluminum alloy

(4) when installing hardware with fastening screws, a metal lining plate must be set inside, and the thickness of the lining plate should be at least twice the tooth pitch of the fastener. It shall not be fastened on plastic profiles, nor shall non-metallic linings be used

(5) hardware fittings should be installed after * and door and window locks, handles, etc. should be assembled after the window and door leaf enter the frame to ensure correct position and flexible switch. In China, attention should be paid to the maintenance of hardware after installation to prevent rust and corrosion. In daily use, open and close gently to prevent damage caused by hard opening and hard closing

hardware accessories are the components responsible for the close connection between the frame and leaf of doors and windows. Without its existence, doors and windows will only become dead leaves, which will lose the significance 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 indicators of doors and windows include: wind pressure resistance, air tightness, water tightness, heat preservation, heat insulation, sound insulation and compression resistance. The effect of hardware accessories on the first performance of doors and windows and the wind pressure resistance determines the success or failure of doors and windows; Similarly, air tightness, water tightness, heat preservation, heat insulation and sound insulation are all related to the sealing of doors and windows with the participation of hardware accessories. The lock points and lock seats of hardware accessories are distributed around the whole door and window. When the doors and windows are locked, the lock points and lock seats are firmly buckled together and matched with the hinges (hinges) or sliding braces to produce a strong sealing and pressing force, so that the sealing strip can be elastically deformed, so as to provide sufficient sealing performance for the doors and windows, and make the leaves and frames form a whole, which can greatly improve the performance of the doors and windows. Similarly, the mechanical performance indicators of door and window folding (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 light components, and their use energy consumption accounts for more than half of the building energy consumption, which is the top priority of building energy conservation. In the design, we should fully consider the energy conservation of doors and windows, that is, thermal insulation and thermal insulation. If there are no more lock hardware accessories, no matter how well the doors and windows are made, its thermal insulation and heat insulation can be imagined

3. Similarly, the anti-theft performance of doors and windows is also a concern of the owner *. In this regard, 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 a variety of window shapes and structural forms, and various functions of window types all depend on the configuration of hardware accessories. Imagine that the market demand for cathode materials is very considerable. Without hardware accessories, how can the flat opening lower hanging window achieve the function of both flat opening and inverted? How to realize the function of pushing, pulling and folding in push-pull folding doors and windows? Which one does not rely on the function of hardware accessories to achieve its unique specific functions, such as internal push-pull and movable shutter? It can be said that hardware accessories are the "heart" of door and window accessories
