Do you know why sticking tape paper on the glass before the typhoon can strengthen the glass?

First, since it is useless to tape, what is the correct way? When the hurricane came, people in the disaster-stricken areas in the United States didn't snap up tape and sticky boards. Really encounter super hurricanes and typhoons, this is the solution. 100% circuit board coverage. If conditions permit, the metal window cover is certainly good. In addition, if the doors and windows are damaged in a typhoon or hurricane, you should avoid and protect yourself indoors for the first time, and don't try to push the door or window with your body. Metal fasteners for doors and windows, tempered glass or laminated glass can't stand it, and the small body of ordinary people is even more useless. It can't stand it at all, but it is easy to hurt itself. Remember to protect yourself, safety first. ?

Second, the recording is just a kind of self-deception placebo. If the typhoon can break the glass, or the branches and billboards rolled up by the typhoon can break the glass, then in the face of such impact energy, the tensile bearing capacity of the adhesive tape is not even a drop in the bucket, but it will help and prevent the glass from breaking into smaller pieces. Originally just a piece of broken glass, if there is tape, it may turn into a large piece of glass with sharp edges and corners, flying out at high speed at the moment of destruction, which is more likely to hurt people. If you put a layer of gorilla toughened film on the whole window glass, 100% coverage, I admit it is still useful; If you just stick a rice word on ordinary tape, or even cover the tape with the kind of spray paint that can be torn by hand, for the popular large-area window glass, even one-tenth of the area is not covered, and the effect is really a drop in the bucket.

By the end of that year, the size of glass was very small, and most of it would not exceed the size of A4 paper due to technical reasons. Therefore, shock wave gas is applied to the single-layer glass.

The pressure is small, and the total pressure is absorbed by the deformation of the window frame. Therefore, the support provided by the adhesive tape is very effective;

Also due to technical reasons, the glass at that time had poor elasticity and was easily broken, and it would not automatically break into small pieces like tempered glass. Mizifang

Shockproof strips can stick to glass fragments and reduce personal injury accidents.

Conversely, glass is generally thicker now than at that time. The glass itself provides great support. The size of a single piece of glass is larger than before

Many, like a big sail. The little support provided by the adhesive tape is tasteless.

Thirdly, the adhesive tape attached to the glass is not only soft but also not connected with the load-bearing object. How can we reduce the deflection of glass when it is blown by wind? To sum up, even if the adhesive tape is attached, the glass with insufficient strength will still be blown up by the wind, and the glass with sufficient strength will not be blown up without attaching anything.

It's broken

The tape stuck only on the glass is a placebo to comfort the frightened little heart. Tempered glass will break into slag, and these tapes that only stick to the glass will fall off into mop head because they stick to each other.

Covered with glass slag, if this mop head is blown around by the wind, it still has certain lethality.

It's best not to insist. The glass is just broken into slag, which is not lethal.

Ordinary glass will break into cut cakes of different sizes. At this time, the adhesive tape plays a role-it can reduce the number of times the glass falls off and slow down the speed of falling off.

The time when the glass falls off the window frame. Merchants can't say, but in ordinary homes, if it's not tempered glass, it may be good to use the word rice (anyway, my community is full)

Is ordinary glass). In this case, it is really useless for you to protect yourself.

But in many cases, the glass is broken not directly because of the wind, but because of other factors, such as the window shaking caused by the wind.

The glass is broken, for example, the wind blows something else onto the glass, in which case the ordinary glass will stick better.

Fourth, answer from the perspective of a structural engineer.

Feel useless

Suppose that the glass is broken under the control of deflection, that is, the window will not break until it reaches a certain deflection.

So will the tape have the ability to resist deflection?

In any case, basically, the deflection is inversely proportional to the second moment of inertia of the section, that is, the greater the second moment of inertia, the greater the direction.

The smaller the deflection. Some people may say that we can make adhesive tape on the curved part of glass, just like the tensile reinforcement in concrete, to prevent deformation.

Well, it's actually a good idea, but glass is not concrete. Why do you put steel bars in concrete? Because it has no tension.

Ah, that makes sense. Tape and glass are not bad for rabbi.

I guess the only function is to prevent the production of large pieces of glass? And a placebo.

Tempered glass, laminated tempered glass and non-tempered glass have no practical significance.

The strength of ordinary tape can't provide enough protection. So it will break or it will break.

If you have to tape it, I recommend 3M fiber tape. This kind of adhesive tape has reinforcing ribs inside, which is much higher than the tensile strength of ordinary adhesive tape.

However, there is still no function to prevent debris. Just a little more serious.

Finally, there are houses with frequent wind disasters. Consider Mediterranean windows. The outermost layer of this kind of window is wooden shutters or boards. There are glass windows inside.

Windy weather can effectively prevent glass breakage caused by foreign body impact. It is equivalent to armored the window. This is much more useful than duct tape.

Fifth, in fact, in order to improve it,

Use wide transparent tape or insulating tape.

Seal the window from the inside, although the glass will still break.

But at least you can get most of the pieces to your crotch. The legacy of old ideas, old-fashioned glass windows used to be so effective, and now this big glass is so thin with tape.

This is a drop in the bucket, mainly because it is easy to clean after it is broken. Broken glass doesn't fly everywhere, does it? For example, when Oni Tsuka went to their home in GTO, Ji Chuan, he put

Stick the dogma on the glass and push it with your elbow. Merchants generally use tempered glass, and it doesn't make sense to stick tape, but the windows in everyone's home are generally ordinary glass, so sticking tape can prevent them from getting too big.

The fragments fell off.
