Hi,
I am intending to build a mezzanine, using ltreated umber (not steel).
The main beams (legs and frame) would be so-called 4x4 beams (in reality 3.5x3.5), and the beams inside the frame that carries the deck would be 68 inch long, 3.75 inch tall, and 1.75 inch wide ( = 2x4x68). The mezzanine main frame (96 inch above ground) would measure 75 inch by 120 inch. The deck is made from the red-edged "construction type" plyboard.
The mezzanine would just carry a small table on the one small side, and a shelf on the one long side. I expect one or maximum two persons using it at a time.
My questions are:
1.
Having a distance of 113 inch between the vertical beams, can the long beams manage that weight or should there be one more vertical beam in the middle?
2
What should be the distance between the 2x4x68 beams that are below the deck to distribute weight well enough?
