PC steel strand

The standard distance is approximately 1.0 m from the pressure plate.

The minimum is 0.7 meters.

If it's any lower than this, the tension becomes almost unbearable.

To be precise, while you can still feel nervous, it becomes difficult to manage that nervousness.

Is 10 cm the standard for SEEE anchors?

I think at least 7 cm is required.

Since the screws in the head assembly are fine-threaded, once they’re tightened to a certain extent, they can’t be pulled out.

*Please be careful—it can be quite dangerous.

 

PC Steel Bars (Gebindestab)

This is an anchor I used quite a bit a while back.

You don't see them much these days, but they are sometimes used as rock bolts.

Like the apartment building, this one is also about 10 cm.

If it's too short, I can't get nervous.

Since these are coarse-threaded screws, you need to tighten the tension bar coupler all the way in.

 

*There is no standard for "coarse-threaded screws."

This is a term coined by Enta. There are two types: "standard" and "fine."
