The invention refers to a method for manufacturing beam elements. Comprised mainly of a reinforced concrete plate (3) on whose underside V-girders are placed (2), whose upper flanges (5) are cast into the concrete plate (3). The elements (1) are manufactured up and down in moulds comprised of foundation and sides where the girder (2) is pressed down in the concrete. The element (1) is easily manufactured and the girder (2) can through casting in the plate (3) support up relatively great forces.<IMAGE> |
