FLOOR INSTALLATION (Shim Leveling Method)
For walk-ins subject to light to moderate loads
Locate the highest point within the perimeter lines. A transit or surveyor's level is an ideal instrument to use for
locating this point. When the highest point is located, mark it directly on the floor and refer to the erection diagram
to determine where the high point is located with respect to the walk-
in floor plan.
One of the most important procedures that will be encountered in
the erection of a walk-in with a floor is LEVELING THE FLOOR.
It must be PERFECTLY LEVEL! If it is not, the wall panel will
follow the irregularities of the walk-in floor which will directly affect
subsequent procedures such as latching, panel gasket seal, ceiling
panel assembly among others.
Using the erection diagram as a guide, select the floor panel that will
be located directly over the highest point and place it in that position
while observing the drawn outline on the building floor.
After the first floor panel is positioned,
it must be properly leveled.
To
achieve this, shimming material of
varying thicknesses must be used.
Cedar building shingles are ideally
suited for this procedure.
IMPORTANT!
EVERY
FLOOR
PANEL MUST BE SUPPORTED
ON ALL FOUR SIDES AND THE
ENTIRE UNDERSIDE, AT LEAST
EVERY 12" BY EITHER THE
BUILDING
FLOOR
OR
BY
SHIMMING.
After the first floor panel has
been leveled perfectly, trim away
the excess shim material so that
none projects from the panel at
any of the four edges.
From the erection diagram,
determine which floor panel will
be installed next and where it
will be situated on the floor plan. Prepare shimming material for the second panel at each point where shimming
material was used beneath the first floor panel. The shimming material thickness must be such that it will support
the second floor panel at exactly the same height as the first panel along the entire length of the joint. NOTE: In
many cases, the shimming material will be the same thickness as the adjacent shimming under the first panel.
