What material/sizes/spacings for your joists? Looks like they are using steel for theirs.
I will be putting two 90x90 cross beams in the floor one at 2mtr on the length of the structure and one at 1.5 mtr on the width that will leave me with four sections approximately 2 x 1.5 mtr, they will be filled with timber the spacing's depend on what size timber used i haven't got the timber as yet.
It's not as good as it used to be, it's quite thin now compared to how it used to be, I've used it with good results but not for anything critical. I'd go for something that hardens a bit more, something like a tractol primer or depending on budget something like a Jotun epoxy primer, probably a bit overkill really but won't do any harm.
Thank you Jim its not really a case of my budget its what i can get my hands on at these worrying times, i will see if i can locate your suggestion if not i will get the primer mentioned and maybe add gloss over the top many thanks.
Hi cracked on today bolted one section to the wall using M12 rawl bolts fixed the leveling legs M22 threaded rod put the concrete block foundations in on the perimeter squared it all up and welded it up in sequence i kept checking for being square and all ended well,
Next job is fabricating the dwarf wall.
if its on the ground you will have to paint,and put some membrane under it
Paint it even if it's not on the ground. There'll be a lot of condensation forming on it.
And close the open ends with plates and welds to stop it corroding from the inside.
If it's airtight the corrosion will stop when all the oxygen is used up in converting steel to rust.
I also think Jotamastic 87 would be a perfect paint for the outside of the box.
You are doing a really nice job there.
Why didn't you weld the captive nuts on the bottom of the steel leaving the top untouched and flat for sitting the wall on
I thought that at first too but he is flipping them over so the nuts are on the bottom. (last pic).
Thanks its just of the ground there is already a membrane in place from decking that was there previously yes i am going to paint reason i asked about paint previously
Thanks i will be doing once all the structure is welded up.
Thanks the structure will only be in place for 4/5 years i was going to fill the ends with expanding form, i will see if i can locate that paint not many places open atm, thank you for your kind words.
I have as Jim says i also extended the plate over the half lap for extra strength on the levelling legs obviously its a weak point i have 6 levelling points on the perimeter i will add more to the floor when i start on that,
You've got it Jim :-),
Many thanks for your input keep safe.
most places are still posting paint etc. out if you order online
Thanks i will have a look this evening and get some ordered.
Hi today's progress,
I need to put a few vertical supports in the dwarf wall but i will do that before the glass goes in.
mind the middle ones
Sorry tom you've lost me ?.
centre box sections for strength
I will be putting a few in Tom i am vertical roof tiling the dwarf wall and need to fix roof lat i have some 70x40 box i will use that for the verticals.
good work,keep it going
I’ve been following this, looking good so far!
If you haven’t bought the paint yet or are struggling to get hold of it, Bonda Rust Primer (AKA Bondaprimer) is great for architectural steelwork and is relatively cheap. I’ve left steel posts and gates coated in it for months with no sign of corrosion. The red oxide stuff that Screwfix etc. sell offers little or no protection (it may actually be porous) and needs to be top coated, I learnt that the hard way!
