Angled Footing Layout


So I have a series of footings to dig, about 10 on an sloped terrain. Squaring a finished height and uniform footprint would be rather elementary positioning sono tubes.

However what I am going to attach is an "A" frame pipe configuration. So the plan view foot provided is based on a point where the legs of the "A" end up at 9' apart. They start at 10'6" They are recommended to be done in two stages. One to depth, place pipe onto footing then shim and top cover to secure.

This is going to be all over the place. Any keep it simple stupid methods to reduce my over thinking would be appreciated.

Having a little trouble interpreting the one drawing with the information given, maybe put up a few more referenced drawings, think it would help.

It's a commercial grade galvanized swing set. So they give you a finished grade footprint with a recommended burial at 23" deep. Then shim and lock it in place.

So they diagram footing like that.

Re: Angled Footing Layout


Okay, so the diagram is of one of the off vertical supports that will hold up the pipe up in the air that the swing will connect to, correct?


I would think the tricky part on that would be to get the angle correct for all 4 supports, would probably make a simple jig of some sort to use to check the hole as I excavated it, just something out of plywood and some 2x stock, have one piece plumb and the other at the angle of the dangle?

Re: Angled Footing Layout


How about just digging straight down, allowing for a bell shape on the bottom to lock it in place? Just a thought.

This was my initial thought but you need an excessive size footing diameter since the combined below grade/ angle would punch out the form towards the top.

The set has 10 legs and it's on a slope. I totally thought about a jig.

It's also 10 ft high and we already assembled it because the owner wanted to fuss with specific placement.

Re: Angled Footing Layout


Im real temped to use my santagelo bar to dig it. I'll drive it parallel to the legs placement. Then pull a leg out finish hole, put leg back in and use a fast set mux........it's a challenge.

They should have a mounted receiver I could attach to the footing in normal fashion. Would make life easier.

Re: Angled Footing Layout


I'd just dig the footers however it was easiest, given the equipment I had. Would either run a power auger at an angle, or scoop them out with a narrow bucket on a mini excavator knowing they would be over sized. Not a big deal if you have to buy an extra yard of concrete, get it done and on the the next project.

Owner wanted this done for Passover. While we were placing rough location Friday a team of landscapers laid about 30 pallets of fresh sod.

I pushed for the machines to dig but too many sprinklers and wiring running around unmarked to risk it.

Re: Angled Footing Layout


I think if I had to do this, I would dig vertical footings in the correct places.
Place concrete in each hole lasered in on level.
Set the swingset in place and fill around it with more concrete.

Probably would add some rebar into the footing so the two pours are tied together...

It is a swing set after all, not a bridge abutment.

My brain keeps thinking that too but with less embedded pipe. I don't know why it should be 22" deep.

There's a lot of force being generated when someone's working it on a swing, better to err on the side of caution.

Re: Angled Footing Layout


I once toppled an anchored swing set with some friends. We were going for record height and had the idea we could achieve a loop-de-loop if we only tried hard enough.

Re: Angled Footing Layout


Manufacturer has poor instructions of course.

One drawing shows a 12" footing 16" in another.

I once toppled myself on a swingset. That was the first time I broke the left arm.

No matter how hard I tried I never could do the loop-de-loop, don't no anyone who achieved the feat.
