Timber Framers Guild Forums General General Forum Questions Anchor plates for slab on grade

I am looking for a supplier for stainless steel anchor plates to attach our 8x8 timberframe posts to a slab on grade. The slab has been poured and there are reinforced concrete piers under the slab down to the footers. I looked on the Simpson Strong tie site and couldn't find anything matching my description. If anyone can point me in the right direction, I would appreciate it.

Thanks,

Harry

Harry,
Did you put some steel plates at post locations in the poured slab ?
deralte ?

I did not put steel plates or anchor bolts in the slab prior to pouring it. Our project in somewhat unusual in that the frame will be raised and then the exterior walls will be completed with Amvic ICFs rather than the usual SIPS panels. The frame will be attached to the walls with HB DW-10HS slip anchors commonly used to attach wood or steel framing to masonry. The foundation walls were also constructed with the ICF blocks and are protruding about 8" above the level of the slab right now. We were planning on just using anchor plates attached to the slab with tapcons.

Simpson does have an 8x8 post base with a SS option (ABU88SS) and they will do custom fabrication
The post base is functional, not beautiful.
Have you considered the post stand off bases with the epoxied threaded rod?
Another option is to design the hardware you need and have it fabricated locally. I have found that the cost is often nominal relative to the headache of making a stock product work.
Do you have to provide for hold-down thru the frame or will that happen in the Amvic ICF system?

J.E.B.

The frame will be anchored down via the ICF Amvic walls. The walls are continuous from the footer up to the top of the second floor and of course are reinforced with rebar. I will look into getting locally fabricated SS plates. That sounds like my best option. Thanks

I found a local fabricator to make our stainless steel plates. He had them done in an afternoon. I had to drill the holes in the plates. I went realllllllll slowwwwww with my 18V portable drill so as not to burn up my drill bits. It worked out well. Thanks
