Except in the case of piers or slab foundations, our posts do not sit directly on the foundation. A more in-depth explanation of how we interact with the foundations can be found on our “Building Details” page under the “Information” section.
The way we attach to the subfloor is broken into two types. If we are sitting on a wood subfloor, we specify that the subfloor does not extend past the outside of the timber frame itself. This allows us to install galvanized tie-straps on the outside of the frame. These are nailed to the posts and the solid blocking under the posts. Because they’re on the outside, they will be covered when the walls are installed or framed.
The second way deals with our frame setting on concrete. When we set posts on concrete, we anchor steel plates to the concrete before we raise. Because the plates need precise positioning, we will drill the anchor bolts and set the plates ourselves. The steel plates have a tab that knifes into the bottom of the post. Once the timber frame is installed, we drill one side of the posts and drive a steel pin into the tab. Once done, we plug the hole so it’s less noticeable.
