Another "will my floor support" question, 265 Gallon

[yogurt_21]

yeah I say reinforce. The fact that it's the garage warrants that alone as it's easy access to get to the joists to reinforce it. So a few dollars now saves you quite a bit down the road.

even if the floor would hold it now, over time it would weigh down on it and either come crashing through or cause major structural issues for the garage.

reinforce now, be happy later. Ignore now, be sad later.

.....not parallel but perpendicular

With my comment i meant tank perpendicular to joists and close to the structural wall, also double joists up parallel to existing joists if this is what you where questioning? I was aimings for the 'over engineer' viewpoint. Given the weight and the possible damage it could cause. This is exactly how i have done my attic while converting, in preperation for a large tank down the line. I used 2"x6" joists doubled up to an effective 4"x6" joist, set apart at 16" centres, over a 13' span. I used those centres since that was the measure used for the existing ceiling joists for the upper floor, otherwise i could have gone even tighter. Of course i only doubled up where the tank will be going, if it does. Time will tell if that was a good choice i guess I had the idea put away to make a large steel framed unit to store the tank on to distribute the weight dependant on what size i eventually go for, should i have doubt in the structure. (like i said, paranoid!)

something wrong with my posts, 'it' wont space anything and use keyboard symbols, no use at all, sorry!

tank with 265g of water falling through floor landing on expensive car = major problem

Im not missing the point, im simply saying if properly engineered there will be no tank through the floor!

How do you think they get steam rollers in top floors in museums? Over engineering the structure

My post also was not direct instruction, simply how i did my floor to accomadate the size tank im looking at, whixh isnt 265 gal, sorry if this is not clear.

Yea the way I will be placing the tank will be perpendicular to the joists.


QUOTE=CA-Delta;4485016;]Excellent question.
If you own your home you can take larger risks at your own peril.
If you rent your home it is not likely your landlord will approve this idea and is more than likely not going to want you to alter the structure.

Regardless, perhaps buiding a temporary wall parrallel to the load wall in the garage using a suficeintly sized beam. You could incorporate this into a storage closet or workbench without actually fastening it to the structure.
Just a thought.[/QUOTE]

The house is my parents. Their house has a in-laws quarters that I am staying in for the mean time. I could do the beam but im not sure really what to do. It would have to be completely unnoticeable. I think if I had to chose I would double brace the joists then run cross bracing with a sheet my plywood on top of that..... Thoughts?

Sounds like what I am thinking about doing. What size tank are you planning on putting upstairs?

Impossible to say for sure without some photo's andmeasures of existing joists, but good theory.

I was thinking around 6' x 1.5'-2' x 1.5'-2'

I never made a final choice, i just used the strongest joists availiable to me and doubled them, so i can calculate tank size in the future.

I am confident that this will be sufficient for the larger dimensions should i choose, dependant on the base unit span. Probably will use a 7ft base to accomadate 6 doubled joists should i go for the larger size, but i will clarify i have done no math on the load yet, and wont go for the larger tank if it is to close to the limits of the floor.

Yours is a big tank, likely requiring closer centre's and possible extra parallel joists.

If that area of the floor contains wiring it could make extra joists a whole lot more costly, hence pictures needed too

What is the span of the joists? You would need to double the joists for the entire span.

another option that sprung to mind, although a bit more costly, is rienforced steel joists.

That would do the trick with a massive safety threshold
