LAY OUT THE BUILDING SITE
After the site is prepared, identifying the location of
the shelter corners helps to square the frame after it is
assembled.
Taking these steps
before
assembling the shelter saves
time and ensures that the structure is positioned as
desired. The following procedure is a suggested method.
Its use depends on the size of the shelter, shelter
application, the footings, and the method used to anchor
the shelter.
SQUARE THE SITE
1. Identify a corner where a building rafter will be
positioned, drive in a stake, and string a line the exact
width of the building and stake in place. (Width of the
rafter is measured from center-to-center of the rafter
legs.)
2. String a line at least as long as the building from the
first stake at 90°.
NOTE:
A transit can be used to ensure an accurate 90°
angle, or the 3-4-5 rule can be used. Refer to diagram.
Using multiples of 3-4-5 such as 6-8-10 or 12-16-20
helps to maintain an accurate 90° angle.
3. After squaring the position of the building and placing
a stake at all corners, string a line between the stakes
to mark the base of the building.
NOTE:
The example that follows shows treated
baseboards set on the site. After marking the rafter
spacing on the boards, the rafter feet are secured in
place.
4. Consult the Framework Assembly instructions for
the building and mark on the ground (or treated
baseboards as recommended) the positions of the
rafter feet.
5. After marking the on-center positions of all rafters (on
the boards or site), remove the strings and continue
with the attaching rafter feet to the baseboards.
ATTACH RAFTER FEET TO BASEBOARDS
The following is an example of one way to position the
rafter feet after the site has been prepared.
This is an
example only
.
The site, anchoring system, and other factors affect
preparing for the rafters.
Consult a knowledgeable
construction professional for suggestions and other safe
and acceptable alternatives
.
ATTENTION:
Placing treated baseboards under the
rafter feet is strongly recommended
when concrete is not
present.
WARNING:
Securing the rafter feet to a baseboard as
shown
does not
anchor the shelter. The shelter must
be anchored as stated in the MUST READ document
included in the shipment.
The above photo shows the rafter feet set at intervals of six
foot (6') on center which is the rafter spacing of the shelter
used in this example.
1. Position the boards on the site as needed to achieve
the correct spacing.
2. If possible, drive a short length of rebar inserted
through a hole drilled in the boards into the ground to
keep the boards in place as mounting feet and rafters
are attached.
3. Secure each rafter foot base to the boards using the
FAJ325B hex lag screw (included).
4. After the boards are set and the bases are fastened in
place, attach the top of the rafter foot to the base.
NOTE:
At this time, DO NOT tighten the bolt that
connects the two rafter foot parts. The upper part will
be adjusted when the rafters are set in place.
5. Continue with the END RAFTER AND INTERIOR
RAFTER ASSEMBLY procedures that follow.
