Raising grainstore roof

[redbaron]

Wondering if anyone has ever raised an existing roof on a portal frame building...eg: remove all roof cladding...dismantle/take down steel rafters, purlins etc...weld extra 4ft onto stanchions...then refit rafters and re-clad roof. Would then need extra or replacement vertical cladding. Could this be cost effective? Getting fed up with restriction in tipping grain trailers!!

Nothing’s impossible but it sounds expensive !.

 

[PSQ]

I'm having serious thoughts along similar lines, but thinking of dismantling an old 1960's portal frame grain shed and re-erecting it as a machine shed across the yard. Then building a new grain shed over a slightly larger footprint but with plenty head room.

We once added some height to some stanchions to add another shed along side the existing one, drilled and plated it plus welded wasnt that difficult if i remember ! But that was the days before the modern building standards !

Grain pusher on the teleporter would be simpler and cheaper

Lift 1st two bays and push it from them.

Take the sheet off above each stanchion
Weld on 8ft extra
Dont frck about with 4ft extra
Jack the roof up 1ft at a time till u are there

Friends in Canada lifted roof off shed.......raised walls then lifted roof back on.

just a screenshot then.

I guess a handful of tall bottle jacks or a few telehandlers would do for the bodging thread.
I like the idea of removing the sheet above the posts and welding 8' onto it.
Weld a flat plate onto the sides of the flat side of the girder and it can only move up and down.....
The trick is getting the other trusses to move up at the same rate.
It could be a project for next weekend.

I lifted my parlour rump rail including all the milking equipment 6”,it could have gone spectacularly wrong but we just about pulled it off.

Buy some Weeks 3 Ton trailers.

jack the roof up is common in the usa they have clamps on the rsj and jack up then bolt the extra in ,, don't take roof off at all

Yes it was done where I work to fit more tattie boxes in they welded heavy channels horizontal between the posts then got 6 forklifts cut the beams lifted the whole thing and welded it all up again it was before My time here but I remember being told about it

Same thoughts here, we have PV as well to add to the headache

I think the biggest risk is twisting which would crack all the panels

Build a new shed.

Build a new shed.

It’s an option but the new shed costs aren’t the problem, it’s the concrete that costs the Wonga.

There lies the dilemma.....

Dismantle roof, then extend the uprights, then reassemble the roof.

 

[Doing it for the kids]

Dismantle roof, then extend the uprights, then reassemble the roof.

That’s the sensible option but a lot of prep work.

The more fun and risky way is to try and leave it all in situ and raise the whole thing in on go....

 

[Luke Cropwalker]

It would be a lot easier to cut the bottom of the uprights and stick a lump in.
