OSE Shop 2011 Interface Plate

This is made of steel and has over 12 feet of welding bead required to assemble each of them

There is a variant used at the roof peak, but it uses no unique parts.

The structures require 5 peak and up to 21 pitched assemblies. (6 for expanded storage)

That means material cost of the parts fabrication:

52 2.5'x2.5' steel plates 26 6"x6"x3' steel square tubing 104 angle plates 6x6x1/8" 104 beam plates 6x6x1/8" 52 angle support plates 1.5"x6"x1/8" 52 beam support plates 4.5"x6"x1/8" 312 linear welding feet

It may also be appropriate to weld the top plates on manually to match the vagrancies of CEB spacing

It may be possible to use rebar instead of tubing for the central link

Review

• Instead of 6x6 tube, use 3/4" rebar welded to top and bottom plates
• Sufficient for bottom plate to be a square 1/4"x12"x12" - because it's a monolithic column
• Top plate - 1' may be sufficient - just enough to attach the beams
• use 3/16"x2"x6" rectangular tubing, slit in half - to produce the u-brackets - no welding, just bandsaw
• Torch a hole through top plate for conduit
