There are several methods for securing a timber post to a solid poured concrete pier, slab or foundation. In this example a flat piece of plate steel with rebar fingers is embedded in to the concrete. Then the elevated post base is attached to the timber post through a knife plate which is held together […]
Timber Frame Construction DetailsFinding the right timber frame construction detail is pivotal for your timber frame project whether it is for a commercial or residential building. We have created this site to provide you and the industry a resource to find these construction details. We welcome everyone to share their timber frame construction details here and comment on the ones we currently have.
Often we find ourselves with a large amount of tension in some connections involving the roof loads and it is necessary to add some steel instead of relying on wooden pegs to do the job. This is not just a new age practice but one that has been around for a long time. An easy […]
There are a few ways to join two rafters together at the peak, one way that we have illustrated before is the tongue and fork connection. In this detail a simple mortise and tenon is used to simplify the process of cutting the joint. Please note that the tenon and mortise are notched back from […]
