the beam. The beam sides and the soffit are cut to a length that will
permit them to fit against the girder side, with the insides of the beam
sides and the top of the beam soffit flush with the opening through
the girder side. The beam soffit rests on, and the beam sides bear
against, cleats attached to the girder sides. This method is used where
the forms for the beam are to be stripped before the forms for the
girder are stripped.
Using Plan B, the opening through the girder sides is made large
enough to permit the ends of the forms for the beam to extend into
the forms for the girder flush with the face of the concrete girder.
This plan is used where the forms are to be stripped from the girder
before the forms are stripped from the beam. The same methods may
be used in framing forms for the beams and girders into forms for
columns.

Suspended Forms for Concrete Slabs
Figure 11-10 illustrates four types of steel hangers used to suspend
forms from steel beams.
The snap-type hanger illustrated in Figure 11-10(a) is a single rod
bent to pass over the upper flange of a steel beam and long enough to
permit the lower ends to extend below the beam soffit far enough to
