The present invention relates to a monolithic cross beam structure which is easily and conveniently connected to a bar girder monolithically extended to correspond to the width of a bridge without multiple segmented cross beams which are mutually connected; which is capable of reducing the number of installed lower piles due to excellent load resistance against a cantilever unit; which facilitates railing construction; which makes it unnecessary to be set up horizontally; which omits the installation of sleepers without changing the size of the cross beam according to the increase in load bearing properties, since an upper flange is located on a connection between the girder and the cross beam; and which reduces the amount of steel bars being used by allowing a longitudinal steel bar to function as a main steel bar. The monolithic cross beam structure according to an embodiment of the present invention comprises upper and lower flanges and a connection for connecting the upper and lower flanges; is monolithically extended to correspond to the width of a bridge; and has insertion grooves formed on both sides of the lower part thereof, wherein the insertion girders has a girder, which is connected perpendicularly to the lower part of the monolithic cross beam structure. |
