Appeal No. 2004-1798
Application 08/883,387
The next step in the construction process is to mount a
service core (102) for a second story dwelling unit on the load
bearing wall panels (50, 52). As can be seen from Figure 5, the
service core (102) comprises a prestressed concrete pallet (104)
and an enclosure (106) formed on the pallet. The deck (108) of
pallet (102) is discontinuous at spaced points and portions
thereof fit into and engage with notches (54) on the load bearing
wall panels (50, 52). Following installation of the service core
(102), a pair of blank prestressed concrete pallets (128) are
mounted to the load bearing wall panels (50, 52) and aligned with
pallet (102) to form the floor of the second story dwelling unit.
At this point, a second set of prestressed concrete, load bearing
wall panels (132, 134) are positioned on the load bearing wall
panels (50, 52) and a pair of shear wall panels (140, 142) are
mounted on the shear wall panels (94, 96). As noted in
column 10, lines 25-28, of Livingston, the shear wall panels
(140, 142) function to enclose the second story apartment of
apartment building (48) and “to maintain the load bearing wall
panels 132 and 134 erect.” At this juncture, the second story
apartment of apartment building (48) is complete and the steps
associated with its construction are then repeated to form
