Hello, everyone.
This is Enta.
Please take a look at this photo.
I actually found it the other day near the construction site in Yamanashi lol
The back is covered with an aluminum cap, and the front is wrapped in concrete.
I've got a pole cone standing in front of my head lol
I suppose a car must have hit this part, causing the aluminum cap to fly off.
In the past, the material used for rebar insertion was raw rebar (uncoated).
However, these days, unless they're temporary, they're 100% plated.
Under the right conditions, it definitely won't rust for about 100 years. (Although, in reality, the estimate is set on the conservative side to account for a safety margin.)
The rebar used in rebar insertion work is galvanized and completely coated with cement slurry.
It hardly ever comes into contact with oxygen or moisture.
AlreadyThe era of aluminum caps is overThat's what I think.
Is there any point in putting an aluminum cap on it and adding rust-preventive oil inside??
There's absolutely nothing, right??
As I mentioned before, the sheath for rebar insertion isn't necessary, and this one isn't needed either.
NEXCO has already stopped using aluminum caps.
Just the plate and the nut, right?
If we remove a few of these, we can install even more rebar.
I want to say this once again to the construction consultants and government officials.
This aluminum cap and rust-preventive oil are not needed at all.
It's a waste of taxpayer money (not that I'm a politician or anything, lol).
These days, there are several types of caps that don't stick out and don't require oil, so it's better to use those.
We live in an era where we can call unnecessary things "unnecessary."
We live in an age where anyone can share their thoughts.
See you later.
