Is my floor bracing sufficient?
 
I am prepping to install a 200 gallon tank in my living room above this brace. I am looking for opinions on how I can make this better. This is my first big salt tank that will need bracing. Thank you all on advance for your opinions.https://uploads.tapatalk-cdn.com/201...df4c2b3a1a.jpg

Will that brace run right down the center and entire length of your stand/aquarium? How are the columns/pillars anchored into the floor?

Totally fine as is... no additional work needed..

I would think it would be fine but for a small amount of money you may want to have someone do the math and inspect ... it would really be bad to miss something and a a failure.

Just my 2 cents

Ok. I switched out the 4x4 with 3, 2x8 sandwiched and anchored together. Had to return the floor jacks and get the next size down. The floor jacks are attached to the floor with 3/8 x 2-1/4 concrete anchors drilled into the floor. I will post a pic as soon as I have the beam up.

Still have to put the big lag bolts through the screw Jack into the beam. But I'm happier with this. I will still have a structural engineer come look at it before I fill the thank... maybe[emoji4]https://uploads.tapatalk-cdn.com/201...d5b63ced55.jpg

Assuming the brace is directly below the tank, you don't need to have anyone look at it. It's overkill for a 200.

Maggie321 01/21/2018 08:01 PM

Perfect I like overkill... this is my protein skimmer. I may need room to grow..[emoji23]https://uploads.tapatalk-cdn.com/201...4848b9d7b8.jpg

That looks pretty secure with the added support, now with all that support you can get a bigger tank ...lol

I'm with the "that's way more than enough" crowd. IMHO, the only thing you might have done differently is to use a couple strips of 3/4" plywood between the 2x8's to stiffen then that little bit more, but as is, it will more than handle a 200.

Much better than the 4x4

yeah and now you can put 4 x 200G tanks there and more..

overkill.. :uzi:
Expect a few hundred at least for an Engineer to state the same too..

I'm about to fill my 500gal tank but I thought I'd check with the forums. Do you think that my additional support is sufficient?

:worried: :blown: :jester:

mcgyvr 01/22/2018 11:18 AM

Is that a butterfly suitcase? Thats sweeeet!!!
Gotta be easy to find that at the baggage claim..

But as far as your support.. I'm "stumped" as to the answer on that one.. :)

Tree is too small and you need to use oak.

I love that you spotted that suitcase.

I'm going to go on out on a limb and say that this was a shady construction method.

That looks to be pressure treated 2x8’s that you sistered together. If so, be sure you use galvanized or stainless fasteners or fasteners rated for AQC lumber. The preservatives used in the lumber are very corrosive to plain steel and will rot a regular steel bolt in short order. You will get corrosion where your posts touch the lumber as well. You can prevent it by using a barrier between the wood and post tops like a piece of tar paper, ice and water shield or asphaltic paint.

You also may want to adjust your posts after the moisture level in the lumber comes down as they will shrink as they dry out.

The screws are coated timberlocks that are holding the 3 boards together. And the lags that went up into the wood are galvanized. I did not put anything between the post and the wood. But there was a (crappy) coat of paint on it. I will watch it. We will keep the screw jacks tight too and watch for shrinkage. Thanks for the info. Much appreciated!

The electrical in the background though :lmao:

The math.... Water weighs 8.34 lb per gallon 200 × 8.34 then check the load bearing capacity on the house Jack's if each one can take 834 lbs you should be fine with the Jack's. Make sure what's under them can also carry the transfered load though. If you put Jack's on a failing surface they will still fail.

JUNBUG361 01/25/2018 11:46 PM

Talking about support in a decent way or ghetto way :D

fishresponse 01/29/2018 11:48 PM

Agree with Dsekula. Do you know how thick your cement foundation is?
