Structural Support
-
The support of ceilings, attics, roofs, and
second stories is based on 1 in aluminum angle brackets attached at
all available corners of the house. These are bolted to the
plywood bases and drilled where appropriate. Very rigid and
light.

Ceiling/Attic Sandwich
-
Closeup of metal bracing ceiling, attic
floor, and roof support layered on the support frame. The roof
is 1/4 in plywood glued to an aluminum channel frame as was used for
the subfloors. The attic floor is similar but 1/2 in. super tuf
foam insulation was used instead of the plywood. It is lighter
and fairly rigid. Unfortunately, The surface has some dents and
irregularities - enough to prevent using as a final painted surface
for the house interior. The roof support is an aluminum channel
frame which is supported by metal hangers shown below. There is
a black plastic washer holding the ceiling support snug. There
is a protruding screw for mounting the backwall to the house.

Ceiling Support
-
The ceiling hangs on adjustable
shelving brackets which can be purchased at any hardware. Of
course they are removable. I might will use these in the future
to support the roof in other areas of the house.

Roof Support Bracket
-
This is a homemade piece of 1/32 in
galvanized steel bent into a hanging bracket. I cut a flat brace
into strips. The brace was found in the homebuilding section of
Home Depot. It will work but I don't know if the above
adjustable shelving bracket would work better.

Outside - Backwall of House Framing
-
The backwall has an aluminum channel
edge around a 1/2 in super tuf foam insulation board - comes in 4 X 8
ft sheets. The frame is glued to the board. Outside of
this is applied 1/16 in congoleum vinyl floor tile to fill the gap of
1/16 in channel edge thickness. Now it is a smooth level surface
for applying siding. The vinyl floor tiles add weight but it is
the only economical solution I can currently think of.

Inside - Backwall of House Framing
-
The inside of the wall needs to be
thicker to cover the edge of the subfloor. Another piece of foam
board was added just filling the gap between finished floor and
ceiling. Another final layer of 3/16 foam board (not insulating
material) will be applied forming the final interior wall surface for
painting or papering.

Notch in Backwall for Ceiling Support
-
I liked using the plastic washer to
snug up the ceiling support bracket. I needed the back to fit
flush against the backwall. So at notch was needed to fit over
the ceiling support bracket.

Inside Garage - semi-complete
-
The floor, walls, and ceiling are
coming together quite well. The wall is not high enough as I
will add a concrete block base to attain the final interior wall
height. The inside of the backwall still needs a final covering
of 3/16 in foam board but this will be done as the wall is
finished. Also, the floor is still just the subfloor over which
the concrete garage floor will be poured. I will probably use
3/16 foam board again as the basic substrate.
