Aquarium and the floor's load-bearing capacity

[erikn81]

I am planning for an aquarium that will weigh around 1400 kg, unfortunately, I have built (or rather ordered) an Älvsbyhus and not a concrete bunker. How on earth am I supposed to reinforce the floor to possibly avoid 900 liters of water and wet sand in the wrong places? The aquarium should have dimensions of 250cm*60cm (the base area, that is). It's quite important that the floor doesn't start to sag/settle since the tank could crack due to shifts.

All tips are appreciated! (Except placing the tank in the garage where there is a concrete slab).

Ask Älvsbyhus to reinforce the joists where you want the aquarium.

It is as elmont wrote.
The ones who know their houses best are the manufacturer, ask them to calculate how it should be reinforced, and ask them to provide the extra material, then you will avoid future problems with insurance in case of an accident.

It might not be relevant here, but how can 900 liters of water plus the aquarium weigh 1.4 tons?

Most likely, you will need to make a significant reinforcement of the foundation structure.
Cancel the Ä-house and build a house where the foundation slab is reinforced for this special case.
It's actually quite easily done.

Well...the glass weighs about 180kg, plus water, sand, and rock, and a sturdy piece of furniture. The weight is calculated with a calculator that takes all the factors into account, how accurate it is I don't know, but it ends up being over a ton anyway.

I realize I was a bit unclear in my first post, the house was built several years ago, but it wasn't me who nailed the modules together,

I’ll check with the manufacturer.

But if it is 250 cm long and placed across the joists (cc60), then you'll have support on 4 joists -> 350 kg per joist. Maybe a bit too much after all (I was going to say that it wasn't that much )

Even if it doesn't work without reinforcement of the floor, you have a point, it might not require insane reinforcement after all!

If you have a torpargrund like me, measure out where the tank should stand and mark it against the ground. I have a 840l tank with a base and equipment, and my tank is only 150cm wide. I roughly measured where I would place the tank and then went under the house to mark where it would be. I took two longitudinal joists and stamped them across the floor joists.

The tank is still standing after a year and a half

I roughly measured where I would have the tank and then went under the house to mark where it would end up. I took two longitudinal beams and supported them across the floor joists.

And by "stämpla," you mean "stämpa," we assume.

If you have a torpargrund like I do, measure out where the tank should be placed and brace against the ground. I have an 840l tank with base and equipment, and my tank is only 150cm wide. I roughly measured where I wanted the tank and then went under the house and marked where it landed. Took two longitudinal joists and braced them across the floor joists.

This answer gives hope :-D What kind of fish do you have?

Scalars, 400tetror, rainbows, eldål

You might build upon the method discussed in this thread:

[mrgorgo]

yes kind of

... avoid 900l water and wet sand in the wrong places?

A few years old thread, so I'm wondering if it got wet in the wrong place or if you've managed to avoid it?

/P

 

[mrgorgo]

At least I've managed.
