Coring Through Masonry Lintel Beam
Coring Through Masonry Lintel Beam
(OP)
Hi guys,
I have not been exposed to much masonry design in the past and have had this situation on-site where services need to pass through a non-loadbearing masonry wall. The cores need to be 2 x 100 dia (4") and 3 x 50 dia (2") and pass through the lintel beam that spans the doorway.
Has anyone been exposed to coring through lintel/bond beams and is it acceptable or should I be looking at moving the locations of the cores or possible installing a steel channel to help strengthen the doorway lintel.
Any help will be appreciated. Attached is a sketch.

The sketch has the cores messing with the end bearing of the lintel. If it is not load bearing, it might work as drawn but I'd prefer the 8" shuffle to the right.

Thanks, like I said I haven't dealt too much with masonry design or spent much time on-site understanding construction practices. I assumed that the cores that run vertical adjacent to the doorway would be core-filled so I will get the guys to move all the coreholes to the right of this.
I thought you guys where in the US. It must be getting late over there.

Moving to the right would be good because common construction practice is to frame an opening with one core of grouted masonry that is usually reinforced with minimal steel. That is normal around the world.
the wall may have been built around the door frame (if there is one) depending on the type of door and location.

Pardon my ignorance on the topic, but I have been using the terms "bond beam" and "lintel" interchangeably. What is the difference between the two?

I know your Australian so time for a bit more reading:

these will give you a better idea.
When in doubt, just take the next small step.
