Structural Filler Material

Structural Filler Material

Structural Filler Material

(OP)
Hi, we want to support an r.c slab to take a line load by the inclusion of an I beam underneath.
The soffit of the slab to be supported is very uneven and not level hence leaving spaces when the I beam is placed.
what can be used to fill the spaces and still provide an even structural support to the slab

Non-shrink grout, like you'd spec between a footing and a baseplate.

RE: Structural Filler Material

What’s the thickness of the gap? It appears to be a wide gap as per your drawing.

RE: Structural Filler Material

I wouldn't try to fill the gap with grout. Just use different thickness shim plates. You don''t have to shim it full length.

@epaenetus, the drawing is not to scale, from 5mm to about 25mm at the maximum
@hokie66, what would be your maximum gap spacing between the plates,the span is 5.2m

RE: Structural Filler Material

I would tend to use plates about 100mm wide, spaced at about 500, so maybe 10 plates for your span, of thicknesses to suit. Then I would just provide a small weld on each to make sure they stay in place.

RE: Structural Filler Material

hokie - is your aversion to grout/preference for shims an ease of construction thing, or is there something else?
