Such durable visors from glass
We all know that there is a safety glass, but we can not see it with our own eyes, usually we see this material either in the windows, or broken on the street( or at home, if not lucky).Although more often you can see transparent or unclear glass peaks above the front entrance to offices or large stores. Held by metal rods brackets or strung wire strings, these canopies look organically on a building of any type.
Fixing rods are made of stainless steel and have a diameter of 12 millimeters. Cables for glass visors are made of the same material, have a diameter of 6 to 36 millimeters and often with the help of a special tube are combined into a bundle.
Under particularly dimensional constructions, many people involuntarily question how reliable they are. Of course, in the manufacture and installation of such awnings there is an accurate calculation. As for glass, it is similar to the fact that it is installed as a front-end in many machines - a triplex coated on both sides with a transparent but very thin film. If, for some reason, it breaks, it will not fall down with the fragments, but only become a network of cracks. What are the canopies of glass?
In addition to rods and ropes, on which the glass is literally suspended, there are also fixators that secure the canopies to the walls of buildings with the help of anchors. I must say that the device of fixators is very well thought out, up to the fact that for different thickness of glass there are different models of fasteners .The main form factors of the hinged fittings are rutiles that are directly inserted into holes made in a transparent awning and holders attached to rudders and having one or two hinges( or without hinges).
However, the cables must also be attached to the walls, and for this there is a separate range of accessories. So, in order for the rope or rod to be firmly fixed to the wall, there are special fasteners with a hook for stretching. The opposite end of the cable or rod should be attached to a special kind of hardware such as "earring", which is combined with the rutile. Stretch marks are supplied with appropriate tips.
What you need to know about glass canopies?
As already mentioned, in order to ensure that the glass roofs are not inferior in strength to the metal roof, they are manufactured using special technologies in three versions: triplexes, bent glass and, finally, triplexes of tempered glass, as the most durable. The usual triplex is made of simple, beating silicate glasses, but due to their gluing with a special kind of film, transparent and heavy-duty , this layered "pie" very well resists shocks.
Accordingly, the tempered glass layers impart special strength to the triplex, this option is used to produce canopies of an especially large area. Since even the gravity of this canopy is already a considerable load, it is not made monolithic, but is assembled from several fragments connected by glass-glass fastenings, also based on the use of rutile. The larger the area of the canopy, the greater the number of stretches and holders should be used. And, perhaps, too many of them can not be, worse, if there are few fixers.
