Deck Post Spacing Chart

Deck Post Spacing Chart - = ~63 psf dead load. I am sparky by trade asking a little help about the deck i would like to build. Using 5v metal for the roofing, i don't think the thickness of the metal is going to matter that much as far as the depth of the screw. From weight and dims to a lumber grade & size & spacing is easy but tedious. I'm building a ground level deck with 2 x 4 joists supported by adjustable post bases, (bison's). After you build it, check the joist deflection under the tub, l/360 or l/720 or whatever is recommended for decks. E.g., 500 gals x ~8#/gal = 2 tons.

Height of the deck is 34 inches. I can't use a thicker joist because of door threshold clearance. Lags should be 1 1/2 from top and bottom of rim joist, leaving 4 between holes. The engineering toolbox website and others have the formulas.

Each post is spaced 4 ft apart. From weight and dims to a lumber grade & size & spacing is easy but tedious. Using 5v metal for the roofing, i don't think the thickness of the metal is going to matter that much as far as the depth of the screw. The engineering toolbox website and others have the formulas. One is to put 12x4 round footers at the bottom of a 42 hole and set the post on that and bury it. Yes, add another 1/2 lag and make both lags at least 6 long.

Honestly, that sounds like a trampoline to me. The engineering toolbox website and others have the formulas. I am sparky by trade asking a little help about the deck i would like to build. Using 5v metal for the roofing, i don't think the thickness of the metal is going to matter that much as far as the depth of the screw. The previous deck was attached to a ledger cut and flashed into the siding, and two treated 4x4 posts sitting on existing concrete patio.

I can't use a thicker joist because of door threshold clearance. From weight and dims to a lumber grade & size & spacing is easy but tedious. The 29'6 is due to yard restriction. Some will put the post on the soil, hammer a few nails in the side of the post and pour cement around it.

Height Of The Deck Is 34 Inches.

The previous deck was attached to a ledger cut and flashed into the siding, and two treated 4x4 posts sitting on existing concrete patio. But anyway if you start at one end there will be 3'6 then a 12'4 driveway then 13'8 to the end. The overall deck will be 29'6 x 12' and 8'h at the highest point. The 29'6 is due to yard restriction.

E.g., 500 Gals X ~8#/Gal = 2 Tons.

The engineering toolbox website and others have the formulas. There's no plywood, it's just 5/4x6 poplar as the sheathing. Lags should be 1 1/2 from top and bottom of rim joist, leaving 4 between holes.

= ~63 psf dead load. Yes, add another 1/2 lag and make both lags at least 6 long. Each post is spaced 4 ft apart. I believe code will not allow a new ledger mounted deck to be supported on the patio but i thought it would allow a small freestanding deck to do so on four posts with proper set offs and wedge anchors.

I Am Sparky By Trade Asking A Little Help About The Deck I Would Like To Build.

I have an existing 20 year old pt deck 12 x 16 2x8 joist spaced 16 oc double 2x10 sandwhich beam 8 foot spaced 4x4 posts which have 8 inch concrete piers. After you build it, check the joist deflection under the tub, l/360 or l/720 or whatever is recommended for decks. I'm building a ground level deck with 2 x 4 joists supported by adjustable post bases, (bison's). One is to put 12x4 round footers at the bottom of a 42 hole and set the post on that and bury it.

Let me explain the deck first. There's no insulation because it's just a roof over a deck, not an enclosed space. The overall deck will be 29'6 x 12' and 8'h at the highest point.
