The invention relates to a groove steel-concrete integration beam, belonging to the bridge support element area, which can be used in track bridge; railway bridge; and road Bridge. The invention comprises a steel box beam whose top is open, concrete filled in the inner side of steel box beam and the anti-cutting connection element welded on the inner side of steel box beam. wherein, said open steel box beam is formed by a bottom plate and a middle plate, whose sections are in U or W shape; the anti-cutting connection element can integrate the steel beam and the concrete as a whole to display the anti-compression property of concrete; the steel plate can resist the pulling stress of each direction and avoid surface breakage; and the anti-cutting connection element can transfer the shearing force between steel box beam and concrete and avoid their separation. The invention has the advantages of simple operation, application of avoiding surface breakage and wider application prospect, as well as the advantages of initial stress concrete groove beam. |
