U PC Precast Concrete Dapped End U-Girder

摘要

The present invention relates to a U-shaped PC girder having wedge stem portions, and more particularly, to a U-shaped PC girder having wedge-shaped stem portions at both ends of a U-shaped PC girder so as to protrude wider than a girder height and a width larger than a girder width. It relates to a U-shaped girder having a reduced PC systems and widening one to solve the problem shear.A preferred embodiment of the present invention is formed to have a cross-section of a rectangle with a predetermined length, the central portion in the longitudinal direction and the U-shaped body is to have a U-shaped cross-section of the upper open space portion is formed; Wing slab that extends in the horizontal width direction outer side is formed in the width direction both side upper ends of the U-shaped main body; A center mounting portion formed at both ends in the longitudinal direction of the U-shaped main body and protruding from the upper end of the U-shaped main body to a position spaced apart from the upper end of the U-shaped main body by a distance smaller than the width of the U-The U-shaped body is formed so as to protrude outwardly from both side surfaces of the central mounting portion at a length smaller than the protruded length of the U-shaped body at both ends of the U-shaped body so as to be wider than the width of the U-Shaped body, and a stem portion having a sheath tube embedded in a parabolic shape extending to the other longitudinal end of the U-shaped body through the inside of the U-shaped body, the sheath and the upper fixing groove is formed on, the sheath tube being embedded in a parabolic shape in the fixing groove on one side to the fixing groove on the other side, the side mount portion Is embedded in the sheath, the tube extending through the longitudinal section through the side outer characterized by sequencing to the girder and the girder adjacent to the continuous arrangement of the girders.;
