My deck has 12' joists and is 20' wide. It's attached to the house by ledger board. This is in Connecticut and house was built in 2013 to put into perspective the building code at the time. The builder specified four 4x4 posts to support the deck. The beam underneath the deck comprises four 2x10s sitting on top of 4 6x6 posts. We upgraded the 4x4s to 6x6s for added strength and for the look.
We are now looking to pour a concrete pad underneath and to do this we are going to be temporarily supporting the deck and removing the 6x6s.
I'm hoping you all feel if I remove the two center 6x6s the two outer 6x6s will be enough to handle the load of the deck, a gas grill (maybe 300 pounds) and of course family members.
The two outer most 6x6s that I'm hoping to leave are about 1 foot in from the edges of the quad beam
Is this enough? Can it be supported by those two 6x6s if I say upgrade the quad beam? Can I upgrade the 6x6s to leave the existing quad beam instead?
Thank you!!! Need to do this by Friday so I'm hoping some of you guys can respond today please!
Just added photos at the above link they were to large to add directly. The outside posts are only about 10" in.
