What is really wild about a Deltec home is that there are no interior bearing walls. What this means is that you can put the interior walls any where you want because none of the roof trusses bear on them. The trusses are only supported by the exterior wall and a center ring and collar hold them in place. You may be thinking, Yeah, right! Or you may be thinking, Cool!
It is pretty amazing so here are the photos starting with the work to get the walls ready.
Jim Burleson (on the right) and Johnny put in the top corner plates.
Harry installs some of the pre-cut top plates that the jacks and one of the hip trusses will rest on.
Bobby Coxe, the crane operator who helped with all the floor trusses is back - with watermelon and doughnuts - and lowers the compression ring into place while Jim B. positions it over the truss jig.
The trusses are lowered into place and Jim B. nails each one to the compression ring through pre-drilled holes in the ring.
The corner hip trusses are added first and nailed into the compression ring - alternating corners.
The space starts to get really tight for Jim as more corner hip trusses are added. Harry positions the truss over the corner of the wall. It doesn't sit on the top plate it sits between them and has a block of wood that has already been pre-cut and nailed to the truss.
Jim B. moves to the top of the trusses and continues nailing them into the top of the compression ring while Johnny nails them in below and Harry positions the truss over the top plate. The hip trusses in the center of the wall fit into a notch that is created in the Deltec factory.
Before all the hip trusses are added Jim and Johnny position the Tension Collar. It is a steel collar that is bolted around the inside top and bottom of the trusses where they press against the Compression Ring. It is the dark steel collar you can see at the center of the photo.
You can see the Tension Collar and a few of the bolts as well as the top part of the truss jig.
The base of the jig sits on a steel plate on the floor. It is adjustable so that when the first truss goes in the crew can make sure the height is correct. It stays in position until both Tension Collars are securely bolted in place all the Jacks are added and plywood is nailed down on top of the trusses.
The crews day ended after the hip trusses were installed.
Jacks are trusses that are attached to the hip (in this case each corner hip) and then extend down to the top plate.
By the time we arrived on this day all the jacks had been installed and the crew was almost finished attaching the sub fascia board (the strip of wood that all the trusses in this picture are connecting to).
Alan adds a truss anchor to each truss. They are sort of like like hurricane clips. They keep the roof truss anchored to the wall in the event of high winds.
