Patio framework

[EasyCash]

Hi.

Do posts for the frame of a sunroom need to stand directly above a foundation block, or is it okay for the post to be slightly offset between two blocks anchored in the beam?

This is for a sunroom approximately 6.5 x 4 meters.

The distance between foundation blocks is under two meters and floor joists are on 60 cm centers. Dimensions 45x170.

Hello.

Do the posts for a frame of a sunroom need to stand directly above a pier or is it okay if the post is slightly offset between two piers, anchored to the bearer?

The sunroom is approximately 6.5 x 4 meters.

The distance between piers is under two meters and floor joists are at cc60. Dimension 45x170.

The posts and frame will be made of glulam.
Posts 120 x 120. Roof beams 56x225.
Polycarbonate roofing, 32mm.

Hello!
Given the dimensions you have for the timber, it sounds like a conservatory frame from Skånska Byggvaror. Most of the weight from the front of the conservatory and the roof, including snow, lands on the front posts. I would have chosen to have a plinth underneath to reduce the risk of future settlement. A little extra work to avoid having to redo it later.

Can you access to reinforce/double/triple the support beam?

Hi!
Considering the dimensions you have on the timber, it sounds like a patio framework from Skånska Byggvaror. Most of the weight from the front of the patio and the roof including snow lands on the posts at the front. I would choose to have a footing underneath to reduce the risk of future settling. A little extra work to avoid having to redo it later.

Not Skånska. I have looked around and gathered inspiration from several suppliers. It seems I might have to build separately since the height is not on my side.

Can you access to reinforce/double/triple the bearer?

Everything is possible, but it is clear that it will be troublesome. As I have it now, a post will end up about 70 cm from a plinth.

50% of those I asked say that you can just screw everything directly onto the decking if the underlying joist is correctly designed, regardless of the relationship between post/plinth.

50% say that a post should be directly above a plinth.

Depends on what the roof looks like and how much load comes down on that column.

Hi @EasyCash!

I have the same question you had. How did you end up doing it?

Everything is possible but it is clear that it will be tricky. As it is now, one post will end up about 70 cm from a foundation.

50% of those I asked say that you can just screw everything directly onto the decking if the joist under is properly designed, regardless of the relationship between post/foundation.

50% say that a post should be directly above a foundation.

So how did you do it? I'm in the same situation.
