What are the precautions for large glass sealed balconies?
99% of owners who have a low budget and insist on making large glass will step on the pit. Because of the beautiful atmosphere, there are more and more large windows to seal the windows. In the past, it was still very rigorous to make large glass, and the calculation parameters of wind resistance were all basic operations. Now the short ** rises, a lot of laymen or decoration companies or decoration bloggers talk nonsense on the Internet, these ** are very large and do not fully understand, causing many people to blindly follow the trend to make big glass.
Now the involution of the door and window industry is also more serious, and many businesses can only take orders at low prices in order to survive, and they will definitely make money if they take it. So what to do? Cutting corners, many owners don't understand, just load it up and receive the money. These industrial garbage are not for money but for life, so the small workshop roadside store will not think about what to do if the glass is broken and falls down and hurts people? I don't think about the depth of the glass in the groove under negative wind pressure is not big enough, and the glass will fall out of the groove.
Once again, I advise everyone who wants to make large glass owners, first of all, the budget must be sufficient, and secondly, the choice must be professional enough. How to see if the merchant is professional? 4 points to teach you:
1: Will the strength of the wind pressure resistance be calculated? When the doors and windows are subjected to wind pressure, the main stress plate deforms the glass, and the stress point is directly transferred to the middle stiffener, so the structural strength of the middle stiff directly becomes the weakest link in the frame structural strength. Professional merchants will calculate the strength of the profile by the structure of the profile, the surrounding environment, the city to which it belongs and the height of the floor.
2. The strength of the glass itself. Whether the thickness of the original film meets the relevant national standards. In order to prevent self-explosion, there is no upgrade to do ultra-white glass or homogenization treatment.
Three: whether the notch has a multi-functional crimping line. According to the specification, after the glass is thickened, can this glass be put into the slot, and some businesses have a notch that is not large enough to compress the thickness of the glass, which must have a great hidden danger in the later stage.
Four: What is the depth of glass into the groove? The larger the glass, the greater the possibility of deformation and the greater the stress area. At this time, whether the depth of the groove meets the relevant standards of wind pressure resistance.
So after asking these 4 questions, it is basically clear whether the business is professional enough. Therefore, if you want to be a big glass owner, you must keep your eyes open, choose a professional business to serve you, and don't leave yourself with potential safety hazards.
Pay attention to me to buy windows and not roll over!
