[Lerftest] LERF Gallery Raised Floor

[Joseph Gubeli]

The images below are, in general, what I imaging the raised floor will
look like behind the SSAs. The grating is 1” x 3/16” (18” x ~34”) aluminum
with a safe load of 632 lbs per square foot for a 24” span, our
unsupported span is 15”. The channel is 6061 aluminum 4” x 1.58” x 0.18”
anchored to the floor with ¼-20 bolts spaced 18” apart. The “L” brackets
will keep the grating from sliding much. More of this raised floor could
be added to extend to penetrations. Let me know if there are a questions
or comments.



Thanks, Joe
