1, door and window systems
What is the system? System is generally from each other and interact with some of the things composition. You can also say that the overall system is part of the association. On the unit and the overall comprehensive analysis of the composition of the final composition, refers to a single unit or only concerned with the overall macro, not the view of the method of the system. System is an organic whole, elements of the system and the system is composed of different elements is a relative term, in a system of elements is something, at another level it may be a system, there is between the whole-part therebetween relationship.
Door and window hardware systems: door hardware in the usual sense, the only doors and windows accessories. Although there are "hardware accessories is the heart of the doors and windows system," saying, but not actually get real attention. Door hardware is (the term "handle" is provided by industry Encyclopedia) by the handle parts, transmission parts locking hinge parts, accessories, etc. together organically, through supporting collocation and integration technology systems and services in subsystems windows system. Also need to have technical support and after-sales service system. We can not simply say that one hardware products, we can not abandon the individual hardware components and talk "window hardware systems" concept. Should establish a systematic philosophy, for a variety of hardware products and make the appropriate planning. In the large "windows systems" framework, profiles, glass, plastic strips, processing, and even change the way the doors and windows open, doors and hardware are required to make the appropriate changes to better serve the doors and windows.
2, aluminum doors and windows in the doors and hardware matching system
In considering the windows system, optional hardware problem, you first need to have an overall window systems research and understanding. In particular, the size of the design and selection of profiles, we can say there is no good cornerstone profiles do, what kind of hardware also eventually make a good door. To profile and hardware for comprehensive consideration of selection, after careful not selected profiles, then select Hardware. This situation can sometimes lead to a non-standard due to the profile and can not find the hardware is equipped with. Now, after most of the real estate business will be considered with the profiles and hardware, and give to trade-offs. Choice of accessories to consider its versatility and rationality, taking parts production processes and material quality. Of course, there has optional, this situation is certainly optional hardware will bring difficulties.
Load (the term "load" is provided by industry Encyclopedia) Optional accessories for doors and hardware requirements: Hardware matching, first make sure the doors and windows of three features (wind pressure, water tightness, air tightness) and insulation, separated thermal, acoustic and other performance requirements. In 2012, the Ministry of Housing and Urban re-enactment of the GB50009-2012 "building structural load specifications." Temperature effect, variable load, accidental load, permanent load, wind load and mountain terrain height variation coefficient correction factor (the term "correction factor" provided by industry Encyclopedia), and so do all kinds of parameters increase and adjustment of wind content and methods of calculation of a lot of vibration to improve and perfect. Adjusted basic snow pressure in some cities and the basic wind pressure values plotted a new national basic snow pressure and basic wind pressure chart. Our calculations to provide a more detailed theoretical basis.
In different regions, different environments, wind pressure requirements for security doors and windows are not the same, and comprehensive basis for calculating various parameters to determine the location and the number of red dots to ensure that the performance requirements needed. In general, the lock point, the more strong wind pressure performance of windows and doors. At the same time, we must consider the configuration lock points, only reasonable choice in the case of the doors and windows locked and layout of the number of points, will enable multi-point lock to play the most effective role Kuang. Under the premise of ensuring the performance of windows, locks point layout optimization, reducing hardware cost, is the best combination. Calculate the number of points on the lock is more complex, in this recommendation to simplify a lock point formula:
Let n be a lock points; W a width; H a high; Wk a standard pressure; a safety factor of 2.5 times, n = W × H × 2.5Wk / 0.8 (a)
