Installing PC Steel Strand Connectors (Part 1) | Basics

Hello, everyone.

This is Enta.

The other day, I got a call from a former general contractor for the first time in a while.

They said they'd like us to handle the next construction project.

Wow, I'm really happy about that.

To be honest, I'm really happy that you keep inviting me back like this.

There are as many subcontractors as there are mountains (though there aren't many these days, lol), and they're choosing us from among them.

We want to proceed with the construction steadily and reliably!

But that's beside the point.

At the anchor installation site, the prestressed steel strand was driven in too far because it was driven too deeply.

So, this time I tried connecting them using PC steel wire couplers again.

 

Please cut the PC steel strands so that all the couplers are concentrated in one place and do not interfere with each other.

PC Steel Wire Cutting

It's a little hard to see, but I've adjusted the cutting position of the PC strand to account for the length of the coupler.

Since this was a removable anchor, I cut the two steel wires at the same point.

Since there were eight pieces in total, I cut them into four different lengths.

I made sure that two of them were always in the same position.

 

The important thing here is to make sure you color the same steel wire.

Since PC steel strands emerge at each of the four U-turns, there are eight strands in total.

I set aside one set without any color, and divided the remaining three sets into red, blue, and yellow.

PC Steel Strand Coupler

Color-code the connectors in the same way.

Doing this will prevent you from mistaking the PC strands when under tension.Connection Coupler

Install this.

Connection Coupler

Insert it all the way into the PC wire, then tap the head with a hammer.

It fits about 1 centimeter. If you don't insert it securely, it may come loose.

Connection Coupler

I tried connecting them one by one.

Next, a coupler of the same color will be placed horizontally on the other PC steel strand in the same way.

I'll continue tomorrow.

 

See you later.

    Hello, I always enjoy learning from you.
    I'm sorry I keep asking the same questions every time.
    I’m a manufacturer of slope protection mats, and we’re currently proposing our products for a construction site through a trading company.
    The trading company was supposed to act as an agent and provide it to the contractor, but,
    Apparently, the general contractor contacted us to say that since the site design calls for tens of thousands of plants and the request was made in conjunction with the landscaping work, they could not approve it.
    So, I have a question: Would the contractor you’re working with specialize only in slope stabilization, and would landscaping be completely outside their area of expertise?
    The trading company found a contractor specializing in mat installation, but since they’re a slope stabilization contractor, the trading company decided and told us that planting wouldn’t be possible. Is that really the case?
    Since there was quite a large quantity, I just couldn't bring myself to give up, so I'm thinking of asking an acquaintance at the Forestry Department about it next time, but,
    I’m asking this question in the hope of hearing opinions from those of you who are actually involved in the construction work.

    Thank you in advance.

      Thank you as always.

      To get right to the point,
      Planting work is, if anything, the job of a landscaper.

      If there's a site supervisor with knowledge of landscaping, even a slope construction contractor can handle the job.

      Basically,Slope-construction workers specialize exclusively in slope construction; landscaping is a different field.will be.

      What’s more, if you have slope construction workers do the planting, it will take longer if they aren’t used to it, and the workers will be reluctant to do it. (They don’t like doing new things.)

      I know it’s hard to let go, but let’s just cut our losses cleanly. After all, leave it to the experts.

      Next up! Let's move on to the next one!!

        Thank you for your reply.

        I've given up completely!
        You should leave it to the experts. Learning about landscaping has really helped me improve my skills.
        Thank you very much.

          Thank you for your hard work.

          There's no point in worrying about things you can't change, so let's move on!

          Man, I really want some mochi~ lol
