Attaching wooden post to concrete slab
I have someone with a rental house (read CHEAP) that has a porch and stairs with an iron railing. It old and some of the spindles are breaking out.
It uses flanges bolted to the concrete. And all of the parts are welded.
He wants me to replace it with a some of the bolt together iron railing systems from the home horror stores. But with my experience they aren’t that strong. And the set screws will work loose etc.
This is a slab cap that is about 8Ft high on the one side (raised ranch).
I don’t know what is under the slab. Fill, a pan over storage area? So a don’t want to drill a deep hole and put in a pipe.
I have looked at Simpson ABA44 post base. But I am concerned about how much latteral force that they handle and there is such a warning.
And the cap overhangs the foundation so that I can’t bolt from the side.
I did see that Simpson has a fence post base that could be used. But it is HUGE uses 4 1/2″ bolts into the concrete and by the time I installed that there would not be any place to stand on the stoop or steps.
I am wondering if I could use 4 3/8″ galvanized all thread. Set about 4″ in the conrete with epoxy. And 6″ in epoxy in the post. But I am wonder how that would hold over time with the PT drying out. And I am concerned about no way to tighten it up.
I checked online and I might have been mis-remembering the fence base.

I was thought that the flanges where on all 4 sides. But I see that there are only on 2. So For 2 of the post the anchors would be inline with the railing and not in the way.
And if I use the epoxy or acrylic to set the anchor rather than the expanding ones I wonder how close I can get to an edge.

For what it's worth and if I'm thinking of the same thing you're describing, those 'iron' railing sections don't meet code. Don't know if that would be an issue for you or not.
Well you can get some o fthem in with 4" spacing, others are 6".The display at Lowes at one places says meets code. But at another it says check with local building offices to see if it meets code.Interesting the Simpson stuff does not have any approvals. It is listed as a DIY product and advertised for fences. But if it can hold up a 6 ft privacy fence in wind then I am not concerned about the streght..

I have some extra post bottoms, they are 6" tall 4x4 channel with about a 6" square plate welded to the bottom. Green powder coat finish.

About 30$ a PR at Lowes, way down on the floor near the simpson fence post things you mentioned, I THINK they are discontinued, want a picture? I have 6.Spheramid Enterprises Architectural Woodworks

They must be discontinued.I could not find anything like that on USP's site. They had a list od discontinued products and it did not show their either.But I did find that they have 2 fence post connectors. A spike and a pair of mending plates like Simpson shows.I am going to have to go back and see what "brands" that Lowes and HD has.I *thought* that Lowes has Strongtie, but I know that they don't have as big a selection as HD and HD is shown as an HD dealer, but not Lowes.I think that I saw the base at Lowes, but not sure now..

I bought all I could find , just-in-case, and only used 2 so..iffn ya need em, lemme know.
BTW, they worked perfectly for an Ipe rail I did recently, had to pound the post into the base, no screws needed, they have a gappped corner, and expand slightly. Dunno why they'd stop having them, they made a stout handrail attachment easy.Spheramid Enterprises Architectural Woodworks

not much...

use a sleeved ankor (about 3/8") with the belled end (Redheads)....
toss the sleeves....
epoxy the shank into the CC and go for it....
if you drill thru the epoxy will seal the hole up just fine...
1.5" to the edge (had a wet stamp) but I wouldn't trust it... too many possibilities...
But
I think ya left off a T....

I like the consept base. but I am concerned about the strenght.I found this.http://www.ideas-for-deck-designs.com/support-files/titan_anchor_lab_report.pdfIt shows a "strength" of 0.76 kN/m. I am not sure what that measure is of. The best that I can figure out is that they mean a force of 0.76 kN applied at a point 1 meter high. Or converting it that would be 170 lbs at 1 meter high.At 32" that would be 224 lbs. But that does not give any margin for a safety factor..

got me, I can let you know when I get to installing the ones I bought and tell you wether it is solid in respect to what we normally feel as solid. the math doesn't mean a lot to me. I'm a stress tester on site kind of guy. learned it from my 8 year old I think."it aint the work I mind,
