re-inforcing wood frame


here is a good one!
We built a ramp as a prop for a high school musical- actors one at a time walk up and perform. When it was framed- there were (2) 2x3's along the long side of the ramp (it's 12' long)- So I think an 8 footer was used and a 4 footer- This of course causes a weak point (see pic)- One option is to rip it out and put one larger piece like a 2x4 instead- the other thought was to fasten some sort of really strong metal (almost like a bed frame metal) to where the 2 pieces come together to strengthen it- Does anyone have any other ideas on what would work that would strengthen the joint pictured? I think smaller flat metal brackets will work short term but was thinking of some type of longer metal to go across the joint to add the needed strength
thanks!

re-inforcing wood frame


Thanks kwik- We did try that- but then of course- the show changed and now it needs to be moved a few times during the show- we had sort of a "hinged" leg in that area but it proved to be more or a hinderance...... that is what made me think of using a piece of strong metal

Any lumber yard or box store will carry a variety Simpson straps that would help. Longer is better, I'd go with a 24" ST using joist hanger nails. http://www.strongtie.com/products/co...s-hst-lsta.asp

This is really just a scab kinda fix, next time use longer lumber.

Thatís the obvious fix but I figured keep it light and how long will the school play last anyway.

IMO, you should build it at the least with 2x4s in lieu of the 2x3s.

Either that or or make a L or U shaped ramp, thereby building a long lasting structure altogether.

If not a full 2x4 the full lenth. Then
an 8' strip of 3/8 plywood cut to the 2.5" and screwed to the inside over the joint.
and test it with at lesat double (should be 4 times the largest weight you expect to be on it. for strength)
