What to use for ground anchor...

[alan0259]

Just about to build a shed, I'm looking for something made from hardened steel (like a U shape) that I can sink into concrete to put under my base.

I've had a look on eBay but can't find anything apart from ones made from mild steel.

I don't want to pay a lot as I don't need anything pretty, just solid steel.

Any ideas?

Cheers

You don't want hardened steel.

Hardened steel is brittle and can shatter if hit with a hammer. It will be nearly as quick to cut if someone comes with power tools or a gas-axe.

What you want is a really BIG bit of mild steel.

Get a wide, U-shaped piece of steel pipe and set it into the concrete with the bottom of the U down and the top of the pipe flush with the surface of the concrete. Set two long bits of rebar into the concrete in an X-shape across the middle of the U.

Run your chain down through the U-bend.

I used an old Kryptonite U lock after the lock barrel seized up (it fell into the sea, long story).

I set it deep into a concrete shed base with just the top of the U shaped part sticking out vertically.

I welded an enormous D-shackle shut and then sunk it into concrete with rebar. Cheap and simple.

I was lucky with making mine as I used some old 1/4in steel plate and some thick steel pipe cut down. 4 holes drilled through the steel plate, welded the pipe to the plate, painted it all up then bolted it to the floor

I've used old D-locks a couple of times in the past.
I had one concreted into a garage floor, and one was built in to a wall

Thanks everyone, what about these? This guys local and it seems cheap and simple.

I mentioned the U-bend thing because I've seen it done elsewhere and it doesn't stick up out of the floor.

The more I think about it, If you're in there at the concreting stage, a plastic U-bend like you'd use under a sink would be fine, as long as you remember to use the rebar set into the concrete across it. All you need is a tunnel under the rebar to put the chain through.

Then any potential thief would essentially have to lift or smash a large area of the concrete floor to get the chain off. Cutting into steel reinforced concrete is very difficult.

A bit of rebar mesh would be even better.

£60 but it seems good and worth putting in if you're doing a concrete base. Might even save you a bit of cash off your insurance.

Use a Mooring Ring.

Some long cap-head bolts with nuts to give the concrete something to hold onto. Concrete shrinks ever so slightly when curing.

I like mine so much I built my shed around it.

2 bits of solid.metal from work I.just chopped them up and got it welded seemed cheaper and stronger than other ground anchors as its on block paving AMD bricks

Just an.idea

you could look for those giant chain links they used on old steam engine trains, only the jaws of life will be able to cut one of those bad boys apart.

[sidewinder]

I found 3 large links of chain of a crane so sank two of them in ground with part of the third link sticking out

Mine were made by a friend. Bits of steel box section with holes drilled in them, then screwed into the concrete with expansion bolts.

It depends how determined you are to stop them. What you really want is quantity, and a range of complementary materials. Steel mesh reinforced concrete with steel bars through it, forming a large diameter u-shape, deep into a big slab of concrete floor is ideal. The bike quickly becomes the "weak point" however if they are willing to leave the wheels.

Beyond that a "shed" made from steel mesh and concrete with a steel/concrete door is going to be much more effective at stopping a bike thief. Bashing their way through 1ft or 2ft of that is going to take a while...

that is the one i have lol cost me about 50-60... cant remember as i bought it last year lol but it seems very solid!!! my bike is on the front of my drive.. and this anchor is put into the wall on front of my house.. as the drive as been done with "sets" so they could just lift up the brick things (not sure what they are called) so make sure what you are attaching it to can not be moved! could be a very costly mistake!
