Overbuilding a platform

>>1183024
I gotta ask. Is your name R.P.?

what's the point of bolting it to the foundation? that's a shitload of work. just put it on top of some concrete handiblocks. it isn't going anywhere

>>1183032
There are many regions in north america where it is code that it must be not only anchored to the concrete but there must also even be a steel cable fastened between the concrete and the shed.

>6x6
what the fuck
>overbuilding
with no information about spacing its impossible to say, look up joist span tables and take it from there.
>One side bolted to the house's concrete foundation
>One side connected somehow to the already existing deck
sounds like a ballache, i would just plant it why does it have to be anchored?

>Am I overbuilding it?
Yes.
>Are there any pluses in overbuilding it?
No, you're wasting money. Are you rich? then do whatever you want. If not, build it out of maybe 2x6. 6x6? what the fuck were you thinking?

OP here

>>1183031
no
I took the picture from google images if that gave you a hint about the name ...

>>1183032
I have two decks
one built (probably) when the house was built (84)
the second, last year
both anchored
one with 2x10s, the other with 6x6s
I probably have some kind of OCD when it comes to strength
When I built some shelves for my kids rooms, I used 2x4 going through the wall anchored to the studs for support and 2x12s as the shelf itself
they are strong enough that they can hold me (180lbs)

>>1183037
searching joist span tables (just guessing here) I found what I should use in the middle (and how close to one another)
my question was about the frame/perimeter

>>1183048
I'm not (really) rich, but the difference in price is not that big
When I built the deck (see above), going from 4x4s to 6x6s increased the price by less than 10% totally worth it in my weird kind of thinking even though I know very well that I'll never put anything on it that would need the "upgrade"
Also, I get a good feeling when I walk on something that doesn't shake at every step

...the fuck?

>>1183140
I said I took it off google images
I think it was among the first
I needed a somehow related picture ...

In these parts anything anchored to structure has to be permitted. Not so if it's free standing.
>>1183032 has the right idea. Plus no chance of unwanted water intrusion because you fucked it up.

Carpenterfag here, any part of the platform over the ground should have posts anchored into concrete footings, usually this is a sonotube at least four feet deep, if using 6x6 as a post usually code requires a 16 inch diameter tubes, 4x4's should have 12 inch tubes.
The ledger(part against the structure) should be attached appropriately, using either red head anchors into concrete or lag bolts/ledger locks into wood at 16 spacing, staggered top and bottom.
If you are not doing this legally, as in getting permits, i would suggest doing no more that seven foot spacing on your posts holding the platform up over the ground, if your floor joists are running in the 12 foot direction 2x10's at 16 in spacing would be fine, if they are in the 15 foot direction then you would need to go 12 in spacing.
The part of your platform that is parallel with the house should have a girder made of either 2 2x10's if the 12ft side or 3 2x10s if the 15 ft side, you can either does this flush, meaning at the end of your joists, or drop, meaning underneath your joists, no more than 2ft back from the end.
Any floor joists will need joist hangars on both ends, you nail them on with 10d teco nails.

As far as overbuilding, what I have laid out for you is over built and will meet and exceed the IRC but you should check your local codes(do a google search). 6x6's are a waste of money for a project like this, unless you happen to have a large amount laying around.

Yeah it will goes somewhere. Handiblocks are a joke.

Bullshit. I built a 12x12 platform with just 2x4 16" OC sitting on 4x4 PT skids 3 years ago. Screwed some 3/8 ply and painted it for weather. Then had about 20 people dance on top of it. Hasn't flown away yet and I'm too lazy to move it. all these so-called carpenters are just looking to extract money from your wallet by overbuilding everything.
no one answered why exactly you need to bolt a platform a few inches off the ground to your foundation. To me taking a fucking roto hammer or w/e to your foundation sounds like a real bad fucking idea..

Why bolt it to your house? For one, the international residential code requires it. Also it is to prevent the deck from moving due to either ground subsidence or wind force. You need to have at least 4 ft of verticle footing to prevent movement from frost, otherwise every winter your shit will move up and down, loosening your fasteners. As far as trying to cheat the guy out of money, #1 I'm not building it so how am I making money off it and #2 OP wanted to over build it out of 6x6 which is way more expensive than 2x10.
TL:DR your a dumb cunt with no building knowledge trying to get someone to build something doomed to fail

No it doesn't. That doesn't even make sense.

>You need to have at least 4 ft of verticle footing to prevent movement from frost,

That is also bullshit, footing depth is dependent on location. There is a big difference in from depth from Yuma, Arizona to Barrow, Alaska

it's called bad decor
