Hello,

I have a 11.5cm (4.5 inches) thick intermediate wall made of calcium silicate bricks in my garage. I want to install a frame for a 200kg (440 lbs) battery on it. The frame would be fixed using threaded rods that go through the wall. Is there any guideline on how much load a 11.5cm (4.5 inches) thick calcium silicate brick wall can support?

The garage partition wall made of calcium silicate bricks is 6m (20 feet) high. At heights of 2.2m (7.2 feet) and 3.8m (12.5 feet) there is a ring beam. In between are the calcium silicate bricks. The frame is flush against the wall and attached to the masonry with four threaded rods (10mm / 0.4 inches). All threaded rods are continuously screwed into the ring beam. What kind of load can such a wall with ring beams withstand?

For 200kg (440 lbs), I would place the frame on the floor or at least on brackets to reduce the tensile stress (overturning moment) on the wall.
This lowers the pivot point.
The shear strength of the 10 rods should be sufficient, but since only the core is effective, I would choose a slightly larger size.

Don’t worry about the sand-lime brick wall; it will hold.
As long as it’s not full of holes like Swiss cheese or anything similar.

Here are a few photos. You can also see the attachment to the ring beams.

If I want to install three brackets side by side (3x200kg), will there be any problems? The brackets would be spaced about 30–40cm (12–16 inches) apart.
