At four locations on the
lauan sheet, short 10” lengths of dowel were attached in a similar
fashion as the longer four foot lengths on the bases. By inserting
these short lengths of dowel into the conduit at the top the entire 4
foot X 6 foot sheet could be easily raised into place by sliding the
conduit upward over the lower doweled bases. The advantage of this
simple design was that each leg had an infinite number of potential
locations which allowed for fine adjustment. Each sheet was raised into
place and lightly pressed to the surface so that the padding was
compressed evenly across the plaster surface. The raised sheets of
padded lauan were intended to support the plaster in place as well as
reduce the vibration from above by distributing it through the one inch
layer of foam padding.
Manufacturing
took the longest time requiring two people working for three days,
however installation was extremely quick taking only a matter of two
hours to install all nine panels. These panels were very successful in
a number of different ways, the most significant being that no plaster
was lost during the floor reinstallation. Other significant features of
this stabilization method was its low cost as well as its ease of
installation. An additional benefit was that each telescoping leg was
later used with a padded cushion during the treatment phase to
introduce isolated pressure to the treated areas while the grout had
time to set. |
