The present invention relates to a prefabricated temporary bridge using a combination of a bottom plate and a molding girder to form the bottom of a pavement layer using a bottom plate without a lining plate and to compose the bottom plate and a molding girder into a single structure, thereby increasing rigidity. The prefabricated temporary bridge using a combination of a bottom plate and a molding girder according to the present invention comprises a pair of outer bottom plates (10); one or more inner bottom plates (20) made of steel materials; the pavement layer on the bottom surface of the inner and outer bottom plates; and the molding girder (30) assembled to the bottom of the inner and outer bottom plates. An inner bottom plate (20) comprises an inner bottom part (21) having a flat bottom surface; a girder joint (22) on both bottom sides of the inner bottom part; and a support beam (23) on the bottom surface of the inner bottom part. |
