post fixing

Car port construction am I OK with these? what stops the sideways movement?

Read the description - it is concreted in

tubes are freely available.

used 10ft lengths are about £9, which will work out less than wood and post fixings and last 10X longer, plus, you won't need as many - four will easily do it, concreted in 2ft deep and with a 6X2 on top to take the joists

I used galvanised steel tube like that for mine. One of the tubes rusted through at ground level after about 28 years. I had to repair it by using an old bucket, cut to wrap around the post and then filled it with concrete like a sand castle around the post.

The repaired post was strong enough to survive a neighbours car being driven into the post. As in only paint left on the post but a big dent in the car.

sorry, I've not made it clear

yes its concreted in, yes you bolt the post at the bottom but that's a fixing on just two sides of an 8 foot post so, the strain on a bolt that in the last 4 inches of the post is not going to stop the post falling sideways, even with two bolts both sides is it ?????

You concrete in the bottom section keeping the cross plate clear of concrete. They are then either though bolted or coach screwed top posts.

To be realistic you should only think of these are anchoring downwards load into ground .... to prevent lateral load you need to look at you design, gallows brackets or similar.

I have always made up L shaped plates from 1/4" plate and weld them to the top

But for those mortals who do not have welding kit?

Although my fears may sometimes be irrational my main worry about carport type structures is their ability to fly in high winds

I have always over engineered to stop them taking off rather than just holding them up

I would never use wooden posts as it is often not easy to see when they are rotting up from under the ground just how much is left

I do not fix 'rafters' on top of wall or post plates but into or on the side as over time the fixings or wood around them may weaken with rust and rot and again it not as easy to see as when joist hangers are used

The timber on top of the metal posts sits on an L shape bracket say 6" x 2" and 9" long (longer if it is joining 2 lengths) and bolted through the side

plenty of fixings for the roof

possibly more suitable and are specifically listed for car ports. Link was at the bottom of the page you posted.
