Patio and Roof Help

[tomjakob]

Redo your planning for the deck.

8 pillars in 2 rows of 4. Place these rows 2.2 m and 4.4 m from the house, respectively.
Use 45x195 as support beams and 45x120 as floor joists with c/c 60 and then a minimum of 28 mm thickness for the decking.
Everything based on the span table here, [link]

(the tables suggest 45x195 and 45x145 but some gut feeling is also needed)

Okay, yes I guess I'll have to do this.

Glulam shouldn't be needed in the support beam. Just make sure you have support all the way down under the load-bearing parts of the frame for the roof/sunroom and it should be fine.

Okay, but I'm thinking if I go down a bit in dimension, will I need to switch to glulam?

What do you think about this?

I have counted with beams in 45x195 at about 2.2m cc

these beams have plinths at MAX 2.05 meters

on top of the beams 45x145mm at cc 60

this will be stable as hell as Dr. Alban would say...

there is some dimensioning help here in some thread... but couldn't find it now
