Table 37.3
* refers to multiple-span beams
The maximum filler width X
for the bracing at tie hole level
(Figures. 37.1 and 37.2) is
determined by the permissible
fresh-concrete pressure and the
type of alignment rail used, see
Table 37.3.
Note
When compensating for gaps
near outside corners or stop
ends, the vertical tensile force
must be taken into consid-
eration. In this case, fasten the
alignment rail with flange screws
on both sides of the filler at tie
hole level (Fig. 37.1).
