U-SHAPED PC GIRDER HAVING BROAD STEM PORTION

摘要

The present invention relates to a U-shaped PC girder having a broad stem portion and, more particularly, to a U-shaped PC girder having a broad stem portion configured such that broadened stem portions are protrudingly formed at both ends of the U-shaped PC girder to thereby prevent falling, reduce mold height, and resolve shearing problems, in which the stem portions are lower than the height of the girder and are broader than the breadth of the girder. One embodiment of the present invention comprises: a U-shaped main body which is formed so as to have a rectangular cross section at a certain length and of which the central portion in the longitudinal direction has a space portion having a U-shaped cross section with an open top portion formed therein; wing slabs which are laterally extended outwardly in the breadth direction in both sides of the top portion of the U-shaped main body; and stem portions which are protrudingly formed outwardly in both lengthwise ends of the U-shaped main body at a breadth greater than the breadth of the U-shaped main body from the top portion of the U-shaped main body to a point spaced upward apart at a certain distance from the bottom portion of the U-shaped main body.
