Stressing the Post Tension Cables

[@MikeJones-rk1un]

This is the best video specific to how tension is kept using those tapered bushings. I had assumed there must be a steel plate at both ends to not damage the crete.

duck job small $

[@503dcccccccccccc]

nope

[@503dcccccccccccc]

plastic cones, concrete is pretty good with compression

[@jessecastillo7585]

Having issue only with my tpms sensors. The old sensors worked fine, but when adding new sensors is says obd connection failed check voltage. My charging voltage checks fine, I have no check engine lights at all. I replaced the receiver module and still can not for the life of me get new tpms sensors to work for my 2012 tundra crewmax. I have no clue it doesn't show any codes just says obd connection failed check voltage 😢

[@chris_kuddi75]

About time I find a video on post tension lmao every time I try to explain to someone what I do for work it’s hard to explain now I’ll just show em

[@eddiebernays514]

why the hell would you do a 12 inch reference mark?? i also hope he seated those wedges better than that lol

[@GoldsConcrete]

Fun little watch, just started getting into post tensioning ourselves !

[@nickfennel]

Excellent!

[@benzo_676]

Just wanna know y didn’t u spray where the wedges were ?

[@SkunkMonkey991]

Years ago I was monitoring post tension 13 stories up. Behind the job in the bay Danny Glover and Joe Pesci were filming scenes from "Gone Fishin".

[@SanAl-ql9hn]

Can I have the name of the machine? Where to buy pls? Tks

[@Bear2Roo]

You didn't seed the wedges?

[@nickfennel]

Yes

[@61riaz]

I'm wondering for this puller machine can someone give me some details and information about this where and how can I get it thanks

[@mvguillen83]

They are available In many different stores. I also work on these pumps and jacks.

[@prasaddasi8079]

Are we must lay p t slab for basement also sir?

[@andressegura5838]

I guess ill use that little pulling machine when i enter rope pulling contest.

[@BigmanHagfish]

Trust me dude you'll most definitely win

[@MrChangCJ]

what holds it in tension once the hydraulic machine is removed?

[@jaysonbono448]

The two wedge anchors he put in there after pulling the cone out.

[@503dcccccccccccc]

wedges

[@catlady8324]

Magic 🪄

[@deldgo2327]

The 2 metal wedges that the guy put in the cavity prior to stress , they bite in to the cable . The machine pulls and i also setting in the wedges at the same time , so when u take the Jack off they stay

[@knightrider693]

Is that dangerous at all?

[@compachun94]

Yes

[@BigmanHagfish]

Yeah you dont want to stand behind or in front of the cable in case of a pull through ( its where you pull the metal cable too far) the ram will shoot out of the hole and will break a bone. And you shouldnt stand behind the cable (on top of the concrete slab behind it) because if the ram were to fall off of the cable it will swing back and hit you and it will hurt and cut you

[@alejandro6turrubiartes672]

What is better for concrete foundation rebar or cable thanks?

[@googhan]

for post tensioning application you need to use special steel wires. regular reinforcemement bars wont do

[@luisalfredoortiz9199]

Que pasa si se rebienta uno

[@crazyhonduras2010]

Si estás cerca te revienta cualquier párte de tu cuerpo la máquina pesa más o menos 80 lbs si te agarra ta cabron. Pero nada de eso pasa si el cable está bien y el concreto listo aparte el trabajo de los instaladores son muchas razones ten cuidado

[@chris_kuddi75]

Btw hate using the 3 hose pump unless is a tennis court

[@attilabodi826]

Tension cables seem great in theory but I think rebar would make it more secure since cables have 2 points of failure since they can slide inside the plastic while rebar is secure all the way though. Since this is new technology only time will tell.

[@posttension3251]

New technology ? We started installing PT in houses in the late 80's now in Arizona over 80% of homes have it.

[@attilabodi826]

@@posttension3251 Good to know. Although I'm looking at it long term. Like how will it perform in 80+ years? I lived in a converted factory loft, it was built with rebar in the late 1800s. The thing is still solid w only small hairline cracks near the roofs from the 70's when they were neglected/abandoned - it's in the northeast so ice and rain is more of an issue here than in AZ. Complete speculation, but here's what I see happening with tension cables outside places like AZ - places that have weather: since tension cables are installed after the concrete dries the concrete near the anchors (the outer edges) will start to crack or near the center since tension is not equally distributed. Since the cables can shift inside the tubes, all it takes is one anchor to fail for the entire cable to be rendered useless. Once one cable fails the rest will follow.

[@rumls4drinkin]

@@posttension3251 I was just listening to some southern builders and they're saying PT foundations will cost at least 4 times that to repair compared reinforced slabs....dunno. I get why they use it for bridges and high rises but for residential I don't think I'd choose it.

[@tavinchurch1414]

Slabs reinforced with bar have great compression strength and will stop cracks in the slab. The pt cables having 33 kips of constant pressure with prevent cracking by forcing them shut and not happening at all. Pt has been around since before the 80’s and will last as long as concrete reinforced with bar as long as no one damages the cables by mistake.

[@benchipley]

Post tension cables have been around since the “70’s and used heavily in commercial hi rise construction since then.

[@franciscepillo3044]

what is the name of the machine used for stressing?

[@nickfennel]

francis cepillo a tensioner

[@msgjr]

francis cepillo A Project Manager.

[@Q50_BadIntentions]

It’s not called a tensioner, it’s not called a jack, it’s called a fucking RAM!

[@seztogaming4186]

Michael Norsby I’ve heard electrical tools get called many different things by many different people

[@7xr1e20ln8]

Out here on mars we call it a puller.

[@mstafford368]

WTF! No remote?!? 😂

[@OKTULSA918]

No remoto

[@jeffreyhunt2686]

Give me rebar and wire all day long.
