Hello all clever wood builders!
I have a house that is extended at an angle and I am now taking down the part of the old outer wall that the extension connects to. The wall has naturally been a load-bearing beam for the floor joists on the 1/2 floor above, and as a replacement, there will be a glulam beam dimensioned according to all rules and without problems. However, directly under the floor joists, there is an old 2x4" (load-bearing beam) that is very cumbersome to remove and I thought of leaving it in place and building on with the glulam beam under the 2x4". If you calculate the shear stress and screw/nail it properly, it should help a bit with the stiffness.
The calculation of the beam says a minimum support of 47mm, but the construction is such that a support of 145mm is practical, so it is generously dimensioned.
Now to the problem: When I am going to create support for the glulam beam, I want it to lie snugly from two directions: both upwards against the 2x4 and downwards against the column itself. Can one consider placing opposing wedges between the support column and the glulam beam to achieve this? How would you secure them in that case?
