Grouting between steel beam and steel bearing plate
Grouting between steel beam and steel bearing plate
(OP)
I have a job where the concrete contractor installed the steel bearing plates out of level. Please see the attached picture. The concrete pier below is 12"x24" the beam is sitting on the pier in the length direction (24") There is a steel bearing plate cast into the concrete. The beam is supposed to be welded to the bearing plate. (The anchors shown are only weld on threaded anchors for erection only.)I was thinking of using a series of plates to complete the shimming process, but in some cases the plate is out of level in both directions, so the plate thicknesses would vary on each side of the flange. After the shimming process, does anyone have any ideas on a grout to use to fill the gaps. Standard non-shrink grout (under a column base plate type) would be difficult to get into the voids. I am open to any other repair ideas also.
Thanks.
Thanks.

But in any case, my first thought is to somehow inject some type of epoxy grout into the space. I would probably contact some epoxy grout suppliers and speak to their technical reps there about sandwiching their product between two steel surfaces.

It appears to me that the top of pier is close to level but the beam is not. I can't say I like the idea of epoxy grout because the "E" value for epoxy is probably much less than that of concrete.
I'm wondering about a high strength flowable liquid grout which could flow into the small gap between beam and plate. There is not much room for placing dry pack grout.

The issue you have is that you need the correct weld gap, that will require shims. You can't weld in the air.

I've had good success working with 5-star grout in a similar, high demand application in the past. We both were able to get some good support from the company staff determining how it would perform in an atypical application, and then the product worked well.
(for the curious, the grout was used to ensure good bearing across an interface despite some weld distortion in the heavy steel elements supporting this operation)
