Span of Attefall Foundation

Hello,

I'm trying to understand all the tables but I'm not quite sure.

I am going to build an attefallshus on stilts.
The house is 4.6 m wide and 6.5 meters long.
I want to use 45x220 for the beam.
I am thinking of 45x170 with 60cc on top of the beam to then lay floor chipboard and flooring on top.

What could my stilt map look like?

Hi,

I'm trying to understand all the tables but I'm not quite sure.

I'm going to build an attefallshus on pillars.
The house is 4.6 m wide and 6.5 meters long.
I want to use 45x220 for the main beam.
I'm thinking of 45x170 with 60cc on top of the main beam, and then lay floor chipboard and flooring on top.

What could my pillar grid look like?

If you're going to have the joist of 45*170, then a main beam is also required in the middle, with a width of 4.6m.

Then there will be three rows of pillars, 4 pillars in the middle row, and 5 pillars in the outer rows.
You can also have four in the outer rows if you double 45*220 or embed a standing hammarband.

Thank you for the quick response.
What is the maximum between the terminals for bärlina? Both in length and also between?

Thanks for the quick response.
What is the max between the posts for the beam? Both in length and between?

The max, of course, depends on the wood dimension.
With 45*220 about 1.8m
With double 45*220 about 2.5m.
But it depends on several factors so it can vary.
But in your case, I would choose double 45*220 as the beam, and 45*220 as the joist.
Then there will be 2 rows of posts with 4 posts in each.
And of course, these need to be solid posts.
