Description

[0001] PRESTRESSED CONCRETE SEGMENT GIRDER WITH REINFORCED RIGIDITY [0002] BACKGROUND OF THE INVENTION [0003]

More particularly, the present invention relates to a prestressed concrete segment girder having increased cross-sectional rigidity, more specifically, a section of a segment girder of a moment section is provided in a box shape, and a section of a segment girder of a moment section is formed in an I or T shape The PS steel wire fusing unit can be provided at a portion where the section between the momentum section and the momentum section is in contact with each other to form a continuous connection fusing unit and the like. By using such additional fusing unit, The present invention relates to a prestressed concrete segment girder having an increased sectional rigidity that can be economically reduced in height and length, because it is possible to increase the performance of a segmented girder and to freely constrain the tension of the segment girder according to the construction process.

In general, prestressed reinforced concrete girders with a steel wire installed on reinforced concrete are limited in the tension force to introduce a steel wire due to tensile stress on the upper part of the prestressed concrete girder when a tensile force is applied to the steel wire And the height of the prestressed reinforced concrete girder is increased as the span of the prestressed reinforced concrete girder is shortened.

Also, bridges can not withstand the tensile force generated by the static and dynamic moment acting on the prestressed reinforced concrete girders over time, so cracks are generated in the deck concrete of the momentum part or cracks are generated in the lower part of the prestressed reinforced concrete girder There is a problem that the bridge can not function as a bridge.

In addition, the bridges cause corrosion of reinforcing bars due to cracks, and the adherence between concrete and reinforcing bars due to air pollution is lowered, which seriously affects the strength of the prestressed reinforced concrete girders, thereby reducing the life of the bridges , It is very difficult to replace the bottom plate to repair or reinforce the bridge, or to reinforce the PS steel wire in the second place from the outside, thus raising the construction cost.
