| (54) | Structure and method of connecting I-Type prestressed concrete beams using steel brackets |
| (57) A structure and method of connecting a plurality of PSC-I beams (PSC-I beams) to
each other using steel brackets. The beam connecting structure, each having a sheath
pipe therein, includes an end plate which is mounted on each of both ends of each
of the PSC-I beams, with a through hole provided on an upper portion of the end plate
to correspond to the sheath pipe embedded in each of the PSC-I beams; a steel bracket
integrally which is provided on the end plate to be perpendicular to the end plate;
a bracket coupling plate to integrally couple the aligned steel brackets to each other;
a bottom connecting plate which is provided on lower ends of the aligned steel brackets
to connect the steel brackets to each other; a connecting sheath pipe which is provided
between the PSC-I beams so that both ends of the connecting sheath pipe are respectively
inserted into the through holes of the neighboring end plates of the PSC-I beams while
the PSC-I beams are arranged linearly; a prestress strand which is inserted in the
sheath pipes of the PSC-I beams and the connecting sheath pipe; and a concrete part
which is filled in a space between the PSC-I beams to embed the aligned steel brackets,
the bracket coupling plate and the connecting sheath pipe in the concrete part.
