best way to reinforce garage storage level joists?

[dirosa]

Hi,

I need to move some heavy boxes (500 lbs?) onto a little storage loft in my garage built by the previous owner. Unfortunately it only has 2x4's 24 OC that go directly into cinder blocks on both sides. Normally i would just sister the joists with 2x8's, but i am unfamiliar with this method of joists going into cinder blocks.

Should i mount a 4x4 directly below the existing joists so they rest on it and then sister them or ?.....

I tried searching but havent come up with anything.

Whatever you do the load bearing points will still be at the joist into cinder block location, if that is ok, beefing up the existing joists might work but I think that will depend on the span. 500 Lbs is a lot of weight and you say some, but how many is some? What you might be better asking are the joist suitable for the implied load??...pinenot

Would be easier to bury the bodies.

Wow, not the response i was looking for.....guess i'll try talking with the guys at home depot

The boxes were just an easier way for me to say my engine crane, engine stand and a set of rims with tires with the future possibility of adding a compressor up there too.

we don't know what the span is.

You can use joist hangers into the block and put a load more in.

I did exactly as joe suggested, joist hangers with 2x12's

thanks for the help
