Post To Concrete Pier Connection

The drawing at the bottom requires a new steel reinforced concrete foundation.

Post to concrete pier connection.

I then use through bolts that pass through the beam and this post extension to complete the connection. In this connection the bottom of the post has a 3 4 stub tenon that is routed into a plywood sub floor. A galvanized steel plate or pvc spacer is used to separate the concrete and the wood. The image to the right from a different engineer shows the exact same thing.

The bcs allows for the post to beam connection of 2 2xs to a 4x post or 3 2xs to a 6x post. The remainder of the 6x6 post laps over the inner or outer vertical face of the beam. Post base timber pier rod plate. Post and column bases secure the bottom of posts or columns to concrete and are perfect for decks or patio covers.

The blue box shows the post to block connection. Log hog screws are used to hold the post to the solid blocking below. The top of the post base straddles the wood support post and provides nail holes which should be filled to add strength to the connection. Figure 1 12 shows the bending moment versus rotation relationship for perma.

The arrows point at the hardware and bolts connecting the post to the concrete lock. I prefer this method because it creates solid bearing of the deck all the way down to the concrete pier. To concrete connection do not behave like the wood post or the concrete pier they connect. Post base on a plywood deck.
