The invention relates to a novel steel box girder top plate unit structure and a manufacturing method. By using the novel steel box girder top plate unit structure, the manufacturing quality and the manufacturing precision of top plate units can be effectively guaranteed when a large steel bridge is manufactured. The novel steel box girder top plate unit structure consists of a top plate, a plurality of connecting plates and a plurality of U-shaped ribs, wherein the U-shaped ribs are disconnected from one another by using the connecting plates; the connecting plates are connected with the top plate and the U-shaped ribs in a penetration welding manner; and the manufacturing precision and the manufacturing quality of the top plate units are greatly affected by welding deformation. The novel steel box girder top plate unit structure has the advantages that welding deformation of penetration fillet welds are reduced by setting pre-deformation of the top plate units; a pre-deformation measure ...
