News name：Function of door and window hardware fittings and preventive measures for damage

News detail：Door and window hardware is not only small parts, it integrates with more fashion elements, doors and windows hardware accessories play a huge role in the windows and doors, doors and windows hardware accessories although very small, but once it is damaged will affect the appearance and function of the whole. Therefore, doors and windows hardware accessories should pay attention to prevent damage while maintaining quality, and do maintenance work ahead of time. Several measures to prevent and control the damage of hardware: (1) the type, specification and performance of hardware fittings should be in line with the current national standards and relevant regulations, and match with the selected plastic doors and windows. (2) a double pulley or a rolling pulley should be installed for the sliding window with width of more than 1m or double glazing doors and windows. (3) aluminum alloy shall not be used for sliding hinges; stainless steel shall be used. (4) mounting hardware with fastening screws must be lined with metal liners, and the thickness of the liner shall be at least two times greater than the distance between the fasteners. Shall not be fastened on plastic profiles, nor shall non-metallic lining be used. (5) hardware accessories should be installed after the door, doors and windows lock, handle and so on, should be placed in the window door frame after the assembly, to ensure that the position is correct, flexible switch. (6) attention should be paid to the maintenance of hardware after installation to prevent rust corrosion. In daily use, light opening and light closing should be avoided to prevent hard opening and damage. Hardware accessories is responsible for the doors and windows of the frame and fan tight connection parts, without its existence, doors and windows will only become dead fan, also lost the meaning of doors and windows. From the performance and function of doors and windows to analyze the role of hardware accessories on doors and windows: 1, doors and windows physical performance indicators: resistance to wind pressure, air tightness, water tightness, insulation, heat insulation, sound insulation, compression resistance. Hardware accessories on the doors and windows of the first performance of anti wind pressure performance, determines the success or failure of doors and windows; similarly, air tightness, water tightness, insulation, heat insulation, sound insulation and hardware accessories involved in door and window seals. Hardware fittings lock point and lock seat are distributed around the whole door and window. When the door is locked, the lock, lock seat firmly fastened together, and the hinge (hinge) or slide fit, for the same strong sealing pressing force, the sealing strip elastic deformation, so as to provide sufficient sealing performance of the doors and windows, fan, box form one can greatly improve the performance of the door window. Similarly, doors and windows folding mechanical performance indicators (opening and closing force, repeated opening and closing), such as opening and closing requirements are inseparable from the requirements of hardware accessories. 2, doors and windows are lightweight components, the use of energy consumption accounts for more than half of the building energy consumption, is the most important building energy efficiency, in the design should fully consider the energy-saving problems of doors and windows, namely thermal insulation and heat insulation. If there is no multi-point locking hardware fittings, doors and windows do better, its insulation, heat insulation can be imagined. 3, the same, doors and windows anti-theft performance is also the owner of concern. In this regard, the anti-theft performance of hardware accessories, especially in the development of intelligent anti-theft door and window components, is playing an important role. 4, doors and windows have a variety of window forms and structural forms, and the window type of all functions are dependent on the configuration of hardware accessories. Just imagine, no hardware accessories, flat open hanging under the window is open and how to realize the inverted function? Push-pull folding doors and windows and how to achieve both push and pull and folding function? In inverted push-pull, movable louver, which does not depend on the hardware function to the specific function of its own can. It can be said? Hardware accessories is the heart of the doors and windows accessories".
