Nice solid job, I'm glad to see you're backfilling holes with gravel and not soil, treated posts will rot just the same if sat in soil. The whole project is resting on those posts so its common sense to get that bit right. I like to have a concrete collar from 6" below ground chamfering a couple of inches up the post,and the post sitting in/on hardcore. It will never rot.

Nice job, put some central posts in sat on pavers to reduce bounce and spread the weight - seems like overkill but if somebody uses a lathe in there or a washer you'll feel it. For a rapid job concreting in the just the 4 corner posts and then setting the other posts on pavers is more than adequate

Yeah I've built a few summerhouses on bases like this, dug the posts in a little deeper than this then concreted them in, this one was on solid stone, it's on a hill & there's a quarry just up the road so 'they' decided to only dig this far in, if the ground is soft i would put a 1ft x 4" concrete pad at the bottom of the hole to stop the post sinking before fully concreting in, the outside frame is the important bit for holding up the building, the joists going across are just like joists in your house, 2" joists @ 400mm centres - Span ÷ 20 + 20mm will give you the size/depth of joist needed, to see what distance a piece of timber will span do the calculation backwards, a 150mm joist is, 150mm - 20 = 130mm therefore - 130mm x 20 = 2600mm . a 150mm joist will span 2.6m, I think how long this took me is irrelevant.

Thanks for sharing this, I'm just about to build my very first deck. Thought I'd got it all sorted in my head but now this has confused me! I'm planning to build a 4.8m x 3.6m deck, deck boards are 4.8m long so I got 6x2 joists in 3.6m lengths and was going to use joist hangers, but I'm now wondering if 3.6m span is too long and if I should put a 4.8m beam down the middle, which would mean using shorter joist lengths? It's going to be ground level but raised a tad where necessary. Appreciate any thoughts on what I should do, cheers.

@Gidjoiner

4 жыл бұрын

Thanks you're welcome 👍 But yeah, sorry, the calculation for 2" floor joists @ 400mm centres is - span divided by 20 + 20mm, the added 20mm is for safety & to reduce any bounce in the floor/joist, You can work it the other way - a 6" joist is roughly 150mm, take off the added 20mm for safety & the bounce, that leaves 130mm, times that by 20, the easiest way to do that is times it by 2 & add the 0 later, so 130mm x 2 = 260mm, add the 0 = 2600mm , so that means a 6" joist will span 2600mm or 2.6m, A 3.6m span is 3600mm, 3600 ÷ 20 = 180 + 20mm = 200mm or an 8" joist. Is it too late to swap your joists for 8" ones?, if not like you say it needs support down the middle or each joist supported individually in the middle, Joists can be canter-levered out 1/4 of their span, so if a joist is spanning say 8ft, it can be cater-levered out an additional 2ft, but the supports would have to be underneath & as you say your's is at ground level & if you could do this you could get a central beam down the middle to support instead, If your garden is sloping slightly maybe you could canter-lever just one side 🤷‍♂️🤔👍

A normal concrete mix is 6to1, (4 gravel, 2 sand, 1 cement) but i always throw a little more cement in, prob making the mix more like 5to1, like i say i prefer a little too much than not enough.

Did you not consider extra supports in the middle of the framing to reduce 'bounce'? Whilst I get that the sides are strong and will support the frame of the structure weight, the internal weight of traffic is not supported at all. I'm planning on creating a very similar flooring framework for my garden mancave but will be adding additional supports to the middle of the floor for extra support. I'm no construction expert so please forgive the questions, but to me, this just makes sense to support the middle of the floor. Great vid tho

@Gidjoiner

5 жыл бұрын

Yes you would need to support the middle with 5x2 spanning 4m. To work out how far a timber would span you reverse the calculation i mentioned, take an inch or 20mm from it's depth & double the remaining width (I know 20mm doesn't = 1 inch ), A 5" joist becomes 4", 4x2 = 8 therefore a 4" timber will span 8ft, in metric that is 100mm (4") x 20 = 2000mm or 2m, there is a slight difference between the old imperial & the metric but old 2" timbers were proper 50mm or more, the modern 2" timbers are not even 45mm sometimes, To span 4m you would need a 9" joist, 4000 ÷ 20 +20mm = 225 (9").

Hi, if it had to have legs on a concrete base, because depending on the height the frame could be packed up on blocks etc.. but if the deck was big enough maybe nothing, it would be heavy enough not to move, maybe tho 4 of these in the link, it might only need one on each corner just to stop it moving, there's some of these metal post supports that have metal flanges turned in inside the sq hole, avoid them because they cut into the post & encourage rot. If the deck was fairly high the legs might need bracing, if you use these supports i wouldn't rely on them to stop it wobbling, when i dig the holes normally i try to dig them deep enough to support the legs, 2ft-ish, i didn't dig these ones in this vid & the ground here is solid sandstone so they didn't dig as deep as i hoped. www.screwfix.com/p/sabrefix-bolt-down-post-supports-100-x-100mm-2-pack/57289
