How to move support legs in a framework truss?

[Toobster]

Hello,

I need to move out the marked support beams on my upper floor. At least 20cm on each side but preferably about 40cm.

How could I reinforce the construction?

1. Add an extra top frame (the diagonal one that the roof rests on) on each post or how should I do it?
2. Use thicker support beams? (the ones marked in red)

The last option is to encase them, but that is not very appealing as the space becomes difficult to use.

Best regards,

Tobias

Hello. How did you solve this? I am facing the same problem..

 

[Toobster]

I added an extra 220x45 on top of everything to add more insulation (changed the roof) and then moved the legs out by 30cm.

Hello, how did you do it ... please explain exactly

I simply crowbarred/sawed off the support legs and put in new shorter ones further out towards the eaves. Since the roof truss itself was substantially reinforced, it was deemed to be OK.

I simply pried/sawed off the support legs and added new, shorter ones further out towards the eave. Since the truss itself was significantly reinforced, it was deemed to be okay.

what have you done with the överrarm

 

[Toobster]

Before and after for the support legs. On the upper arm itself, a new one was added to increase the thickness of the roof according to the picture here as well..

For me, the overram is 50 x 130 ... what should I put on ... should I just reinforce the overram under the moved support leg.

 

[Toobster]

My upper arm was 38x145 so it became more than twice as strong.
If you're unsure of what to do, it would probably be safest to get help from an engineer who can calculate it.

ok did you apply for a building permit and how much does it cost...could you please draw on pictures how you placed the new upper frame

 

[Toobster]

I applied for a building permit to raise the roof and add insulation. I don't have a computer so I can't draw, but the new one is on its side on top of the old one.

I applied for a building permit to raise the roof and add extra insulation. I don't have a computer so I can't draw, but the new one is placed vertically on top of the old one.

does the entire wall from the new support leg to the ridge tile lie (do you need to apply for a building permit for extra insulation)

 

[Toobster]

I roofing from eaves to ridge. At that time, you had to apply for a building permit if you changed the appearance or dimensions of the house. Raised the roof by about 30cm so..
