See attached sketch:
I need to attach a horizontal I-beam (point load in the middle = 2000 N, length = 4 m) to two vertical members with a hollow section of 120/40/3 mm.
This is a home project, and I'm using what I have lying around, so I'd prefer using these hollow sections but if what I suggest in the attached sketch isn't really feasible, please feel free to advise.
The setup is symmetric, and the vertical members will be attached to both walls (the walls are made of lightweight bricks, so I can't put fasteners in 'em to hold up the horizontal beam).
I don't know how bolted connections are designed for this type of combination, so don't shoot me if I'm thinking totally wrong about this one...
as for the drilled and tapped holes, I'd drill the plates first (all four in one stack), have two of 'em welded on the vertical members, drill through the 3mm of wall thickness, and thread them. in that order. + drill again with a bigger drill for the clearance holes, and have them welded on the I beam.
your opinions on this connection please?
