The present invention provides a pedestrian bridge having a prefabricated jointing structure on the upper portion of a column which prefabricatedly easily joints girders on the upper portion of a column, achieves the rigidity on the jointed portion, and improves the constructivity. According to an embodiment of the present invention, the pedestrian bridge includes: a column inserted into the ground to be erected on the ground; left and right inner guides jointed perpendicularly to the left and right sides of a longitudinal direction of the upper portion of the column; left and right outer guides coupled to the left and right inner guides to be movable by a predetermined distance in a perpendicular direction to the column; main girders divided and jointed to the left and right outer guides to be disposed in the lengthwise direction of the pedestrian bridge; wing plate girders disposed on both sides of the width direction of the main girders thereof to be jointed to each other to be spaced apart from each other by a predetermined distance along the lengthwise directions of the main girders; angular pipes disposed equally spaced apart from each other perpendicularly on top of the wing plate girders; and a deck plate disposed perpendicularly brought into close contact with the top surfaces of the angular pipes. |
