RE: Hollow CMU anchors

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I'm in a bit of a rush now but take a look at ER 5560 - I think its got you covered.  This ER is for ITW Ramset Epcon A7 adhesive and includes their umbrella inserts for ungrouted CMU walls.

Subject: Hollow CMU anchors


We are providing braces to an existing CMU wall with skip grouting. We will need to provide anchors at grouted AND at ungrouted conditions. The bracing will occur in two stages. First, temporary bracing will be installed to be followed by permanent bracing. The only anchors that I can find that can be used in ungrouted cells like the Simpson epoxy tie anchor, are not available to resist seismic forces. The ICC Evaluation Report says only that they can be used to resist dead, live and wind loadings. The only thing I can find is the Titen screw that is only good for 200# tension. Way too low for our application.


Is anyone aware of an anchor product for use in an ungrouted CMU cell that can be used to resist seismic forces?
