I wonder what dimension is necessary for a welded square frame of U-beam (with the back outwards from its square center) that is to be inserted instead of cut-out lecakulor blocks in a basement wall (approximately 30 cm from a corner).
The hole will be H=60 x W=60 cm, i.e., slightly longer than the length of a lecablock.
There is no reinforcement in the wall (which was built in the '80s) that I have seen.
What I fear if no frame is inserted is that a block might "fall down", and perhaps the area is load-bearing?, so that what is on top of the structure "settles".
It is a single-story building of 6 square meters (note that it is not a whole house), resting on this wall.
Should a U-beam with the dimension of 10 cm wide handle this stress?
The lecablocks have dimensions of L=50, H=20, W=20
Is there a table somewhere online for what different dimensions of U-beams should withstand in weight?
It would be interesting to see a table, even though I believe a 10 cm wide U-beam would more than handle this.
