Hi,
While doing some work around the building to repair dry rot we came across this beam that was sandwiched between 1 1/8 ply board and bolted together to the beam. After we took the ply out we noticed the cantilver part of beam was held by only the plyboard and bolts. My contractor put these 3x1/4” straps as shown to connect the 14” beam coming out of wall to the 6 ft 6x14” beam cantilever. The 14” stub beam is a 21 ft long. Supported at the wall shown and 21ft away inside the building. Our goal is now to add the 1 1/8” plyboard on both sides and sandwich the two beams again with plyboard and add bolts to hold the plyboards to the beams from both sides.
I am little nervous about this approach and wanted to see how the cantiliver connection be made better. The straps are held by nails at every inch or so and all strap holes are used.
Any advice in the matter? The plyboard solution alone has held well for 30 years so far.
My initial thoughts are having the straps close to upper side will give better anchorage as fibers are getting stretched on top side and compressed on bottom. Having them in middle will be less effective. On second thought I am thinking if this held for 30 years it might work now as well given that we adding plyboard sandwich and straps together now.
