This invention discloses a support device for bridge construction, including a clamp and two crossbeams. The two crossbeams are fixedly connected in parallel to the upper side of the clamp. Multiple parallel longitudinal beams are provided on the upper side of the two crossbeams, and a folding rod assembly is provided between adjacent longitudinal beams. One of the outermost longitudinal beams has a lug. A sliding block is symmetrically slidably connected to the bottom of each longitudinal beam. A retaining plate is fixedly connected to the side of each crossbeam, and the retaining plate has a retaining groove. A limiting step column is fixedly connected to the bottom of the sliding block, and the step column is correspondingly positioned to the retaining groove. This invention uses a large number of longitudinal beams suspended by a crane. After one longitudinal beam is first placed on top of the crossbeam, the crane moves the entire longitudinal beam towards the pier. The step column at the bottom of this longitudinal beam slides from the side into the retaining groove. The guide slope guides and compresses the supporting spring. When it reaches the arc-shaped groove, the step column slides along the outer end of the longitudinal beam, and the step columns on both sides slide towards the ends of the longitudinal beam for support, preventing the longitudinal beam from easily detaching.
