Assembling a micro-lam beam.
Hello all. I have a 4-ply micro-lam beam that I need to assemble. The completed beam will measure 14 foot in span, and 14 inches in height. Since it is a 4-ply, it will be about 6-7 inches wide (I'm not at home now, so I can't measure and give exact dimensions). I was told that the way to assemble the 4 individual beams into one beam is to use 16 penny nails every foot, 4 nails in a row top to bottom. I have 2 questions. First, does this make sense to you all? I am wondering if nails and carriage bolts were recommended as the bolts would weaken the structure of the beams.
Second question - should I also use construction adhesive between the individual beams?
Thanks,
Rob
