Figure 17-11 illustrates an arrangement consisting of a metal deckto-wall
filler strip to connect the deck form to previously poured concrete
walls and columns.
Figure 17-12 illustrates a method of installing a metal filler strip
to close the space for a deck-to-deck connection between two adjacent
deck forms.
Patent Construction Systems
This company provides a flying form system fabricated of aluminum
and steel that is fully adjustable. Patent’s Interform system has a forming
table width, length, and height that are easily adjusted to fit most job
requirements. Integral steel leg sockets are built into each truss module,
ww.EasyEngineering.n
fitted with telescoping steel extension legs for shoring heights of 7 to 20 ft.
Adjustable steel bracing provides 6- to 20-ft truss spacings.
Each forming table is a single, integral unit that can be moved and
flown from position to position with an average-capacity tower crane, as
illustrated in Figures 17-13 and 17-14. Depending on the required table
width, two or three trusses are used. Each truss unit is held in a fixed
rigid position by adjustable diagonal steel bracing. Table trusses are then
spanned laterally with extruded aluminum joists. The aluminum joists
provide the basic surface on which the deck form is mounted.
The modular units are available in lengths of 2½, 5, 10, 20, and
30 ft, as shown in Figure 7-15(a). The trusses and joists are manufactured
with lightweight aluminum. Individual truss modules may be
joined together with splice sets to quickly assemble a specific table length.
