beam support for cracked cmu basement walls
i need a detail for anchoring the top of a w-section against a cmu basement wall that has buldged and cracked. the floor slab has been sealed for radon, so i plan to use epoxy anchors to connect an angle to the floor to hold the bottom of the beam in place. i need details for the top of the beam for floor joist (2x12) parallel and perpendicular to the wall.
i've done this a few times using small hss sections with a welded base plate and drypack between the wall and the tube. it sometimes gets creative to connect the top to the floor sheathing diaphragm...
i don't have the hilti catalogue here... but they may have connection strengths on their website...
you can support the top of the beam by using 2x wood blocking that is lag bolted to the floor joists. the journal of light construction (look up their website)has a nice article of this topic.
