Post And Beam Roof Construction

For those projects the connection is made by lag bolting the timber components together.

Post and beam roof construction.

Timber framing and post and beam construction are traditional methods of building with heavy timbers creating structures using squared off and carefully fitted and joined timbers with joints secured by large wooden pegs. Beams can be solid lumber or be built from lengths of 2 by lumber nailed together with 1 2 inch pressure treated plywood spacers in between this forms a 3 1 2 inch thick beam that is equal to the width of a 4 by post. First roof area assembly the first roof area is constructed with heavy timbered components that are secured to the ridge beam and second floor beams. It is commonplace in wooden buildings through the 19th century.

The next post sits atop this floor beam directly above the lower post and runs up to the next floor beam or to the roof beam. For areas with attic space above flat ceiling ceiling joists are included but the remainder of the ceiling system above is by owner contractor. And cdx fir plywood. Stonehenge is the perfect example of post and beam construction using stone instead of timber.

If the structural frame of load bearing timber is left exposed on the exterior of the building it may be. Post and beam construction has a very similar aesthetic and the joints can look similar but the stark difference is the connections are simple sometimes made with plates and bolts. Exposed ridge beam collar ties or purlins for cathedral areas as required and 6x8 douglas fir plate beams typically 2x12 spruce rafters 2 o c. These timbers are then tied together with collar ties the horizontal members and gusset plates the metal fasteners as you can see in the photo below right.

Some post and beam projects are done without the plates.
