Hi there,
Please see the attached PDF.
We supply containerised (20 foot) fire pumpsets and usually install the seismic hold down brackets flush to the concrete base.
However in this particular installation the container is 40mm off the concrete and we prefer not to make it flush as pipe and electrical now runs through the container and would require re-installaion.
We would attempt to install it as is with the brackets, but there will be 40mm free rod gap between the bracket and concrete.
One idea is to put a 40mm length 100NB or 80NB pipe around the anchors and squeeze the pipe with the nuts - taking away the shear, bending from the anchors?
Or use the 40mm pipe AND pour grout into the pipe. Or do we not worry about pipe and grout at all as the anchors will be fine like this?
These brackets are to hold the container from seismic forces.
Thanks,
