Switch off a brace in the roof truss

[Henrik Vamos]

Would like to move the ventilation unit about 30 cm, but a brace in the roof truss is in the way.
Does anyone know a way to offset the brace?

Can't you move the aggregator along the length of the house instead?

It is along the length of the house that I have it now. It's hard to place it differently considering the ducting.
I can place it as it stands now, but it would have been optimal if I could get it in a bit more.
If it's too big of a project, I'll leave it.
Mainly thinking if there is a reasonable way to brace the post.

It is currently aligned lengthwise in the house. It will be difficult to position it differently considering the ductwork.

If it's too big of a project, I'll let it be.
Mostly thinking about if there's a reasonable way to brace the support.

Having the truss recalculated and rebuilt might cost around 10,000 SEK, while having a vent installer move the unit half a meter lengthwise before moving it towards the exterior wall might be estimated to cost an additional 2 minutes, i.e., a maximum of 20 SEK if the hourly rate is 600 SEK.

Having someone calculate and rebuild the roof truss is a deal of maybe 10,000 kr, allowing a vent installer to move the unit half a meter longitudinally before it is moved towards the outer wall can be estimated to cost an extra 2 minutes of time, i.e., a maximum of 20 kr if the hourly cost is 600 kr.

Aha, now I understand what you mean.
Yes, it is possible to move the unit lengthwise, but it does not fit between the roof trusses.
We have about 950mm between the roof trusses. The unit unfortunately measures 1000mm.

Ah now I understand what you mean.
Yes, it's possible to move the unit lengthwise but it doesn't fit between the rafters.
We have about 950mm between the rafters. Unfortunately, the unit is 1000mm.

Does it take up more than 940mm even if you turn it 90 degrees?

 

[Henrik Vamos]

No, in width about 500mm
But then I can't get the duct connections together.
I'm a vent installer myself, so I have a good grasp of the unit installation and how I should build with low pressure drop. That's why I can't turn it 90 degrees.
It's fine as it is now and I'll handle the duct installation.
But it would have taken up less space if I could switch the roof truss. However, that's where my knowledge ends.

As you can see, the brace is only intended to handle tensile loads. You can replace it with a wire if you like.
My tip is to install a support under the truss, like a standing 45x195 to 2 trusses on each side of the one you want to remove the brace from.
