Arches
Standing the Arches
After assembling the arches correctly on the ground and scaffolding
is in place, you are now ready to start standing your arches.
Important: In raising
your arches the 2 men on the scaffolding (Men #3) will pull
the rope first by putting a small amount of pressure on the
arch. Men #2 on the ground are going to lift the arch into
the air holding it over their heads. Coordinated with Men
#3 on the scaffolding pulling, Men #2 are going to walk towards
Men #1 on the ground. Men #3 on scaffolding will be doing
most of the work by pulling the arch up by the rope. The Men
#2's primary job is to steady the arch while it is being pulled
up. Men #1's primary job is to keep his foot behind the arch
holding it into the footer, and not allowing it to slide.
Important notice for safety: If at any time during
the standing of an arch, you lose control of the arch, Men
#1 & Men #2 must be alert and immediately get out of the
way of the arch.
Placement
of Arch
A
building with no packaged endwalls, the first arch with the
outer angle attached should be lined up with the edge of the
key-way channel. Your arch is now in the air ready to be lifted
onto the 4x4's that are being supported by the jacks on the
scaffolding. Lift your first arch and let it rest on the 4x4.
Line your arch up plumb. Now adjust your jack to obtain the
proper height of the arch. The height of your arch will be
in the manual. This measurement is from the bottom center
of the arch down to the base of the building.
Now stand your second arch by the same method as the first arch,
but Men #3 along with the help of Men #1 and Men #2 will now
lift the arch 2 to 3 inches and lay the overlap of the 2nd arch
onto the overlap of the first arch. Now by using your drift
pins, you will line up the holes.
Helpful Information: In
order to line up the holes properly, you must use drift pins
where the straight panel comes out of the foundation and joins
the first overlap on the next panel on both sides of the building
by using Men #1 and #2 on each side of the arch. Men #3 will
align the holes on top of the building by using two drift
pins.
Now insert your bolts and finger tighten. Move your scaffolding
forward allowing the 4x4 to be no greater than 2 ½ to 3" out
beyond the last arch standing. Repeat this process after you
stand every arch, until the building is completed.
Important notice: Before
moving your scaffolding, brace the previous arch standing
to prevent any sagging that might occur. We highly recommend
finger tightening your bolts throughout the building until
completed. If you want to speed up your construction time,
after you stand an arch, you can go back two arches and tighten
the rib of that arch making sure you have your strapping installed
to keep the building in line. Follow diagram below.
Once you have 3 arches standing you can go back to the rib
between the 1st and 2nd arch and tighten the bolts on the
rib, tighten the joints on the 1st arch, then place and install
the strapping. Repeat this process until the building is completed.
Important Notice: If the bolt holes
of the building start to misalign, stop tightening the bolts
and go back and finger tighten the bolts to correct this problem.
Repeat the above procedure untill finished.
