design live load for bedroom is 30psf, max concentrated load of 300lb. for a den or living room, it is 40psf with a max concentrated load of 300lb, garage is 50psf wit max concentrated load of 2000lb.
^^^^^This is the solution. It’s cheap and will save you some distress in a few years. After about 6 months check the tension on the support and see if settling requires a few more turns.
like a bottle jack?
This one will work on top of a solid cap block. put the cap block under the house with a treated two foot piece of 4x4 wood and get a measurement to the underside of the floor. remember also that the insulation and the black mesh will block a true measurement, so it will need to need to be cut open for the length. these come in a number of sizes. they are adjustable and you can even add a second or third block to get your correct height.
Thank you
Would I need to support even a longer span and have to use two jacks? the safe is 40" wide
I was gonna say....when I worked at Oakwood Homes in the mid-90s, there was huge metal framework under every house/schoolhouse that went down the line. You ain't gonna sag that floor.
Except those of us with very long strides.
stride don't come come into play while I am toilet surfing.Except those of us with very long strides.
But remember to multiply by the square footage of the room you're in. A 10x10 bedroom is 100 sq. ft. x 50 PSF = 5,000 lb total weight "limit." Considering factors of safeties and actual tolerances of the materials and fasteners used...the maximum limit for that particular room (actually more specifically, structures don't always act as units of a room, but rather as larger pieces of the structure as a whole) is higher. There's also a point load requirement in the building code of something like 200 lbs in a 1-inch diameter circle. So your 200-300 lb rear end doesn't poke the the floor with every step you take. But cram a room wall-to-wall with a bunch of 200-300 lb people, and yeah you're gonna put that structure through a stress load that may result in some failure.
So limit yourself to 10 phat girls instead of going for a new record, I got ya.
Go big or go home...wait a minute...you'd already be at home.
Yes. 2 things never sleep...gravity and rust.
