not sure how to calculate the load here, Its for a deck so the majority of the load will be downward. Im not cantelevilering anything off these joists. Im pretty sure these screws will do the job. I'll use some adhesive too, I was planning on use PL is that good enough for this or any other recommendation for glueing wood to concrete
I finally got around to installing my sleepers last weekend (this deck project is a lot harder and time consuming than I anticipated). I decided to wedge anchor a 2X4 laid flat and then screw the sleeper to it. After cutting sleepers the majority of them bowed quite a bit and i decided that using the 2X4 flat would solve alot of problems including not interfereing with deck screw placement.
I finally got the anchors to work, double nutting and deadblow definately help prevent me from overdriving and stripping threads. Still there was a couple wedges that didn't set properly so I put a couple tapcons by those. I also had a hilti concrete nail gun and gave that a try it sank one fine but the rest I couldn't get it to sit, those nails are a ***** to cut I ruined a sawsall blade trying to remove them.
The anchor wedges are time consuming but I think the right way to go, the big drawback is I just read that i shouldn't have used the Zinc ones with the pressure treated wood, so i ordered the galvanized ones online since no hardware store seemed to carry them, hopefully i'll get them by next weekend. I'll install a couple of these in the sleepers I did put in.
