Hand Setting Modular Panels
Modular panels are lightweight, which makes them easy to handle
and erect. Figure 9-41 shows the erection of modular panels, manufactured
by the Symons Corporation, by a single worker. Setting
panels is simplified because the panels are symmetrical; there is no
top, bottom, right, or left side. Modular panels are ideal for hand
setting applications where many forming details are required. The
only hardware required is the interlocking wedge bolts, which simultaneously
connect panels and secure ties.
Inside and outside corners are easily formed by all-steel corners
fillers, as shown in Figure 9-42. Slots in the corner fillers match those
in panels for easy wedge bolt attachment.
Gang-Forming Applications
Because modular panels are lightweight with good strength, they are
ideal for gang forming. In conventional gang forming, large sections,
or complete details of modular panels, are assembled first and then
moved into position for pouring the concrete. Although gang forming
basically uses the same components as hand setting, it offers several
advantages. Gangs are easily assembled on the ground and then moved
into place. Because the unit is also stripped as a gang, the gang can be
used over again without rebuilding, which saves time and material.
