摘要

A bridge section made of light metal including a vertical web, an upper chord section connected to an upper end of the vertical web and a lower chord section connected to a lower end of the vertical web. The upper chord includes a thick-walled horizontal part with a weld seam connection and a thin-walled flange. The thin-walled flange has a wall thickness which is less than the thick-walled horizontal part. The vertical web has a wall thickness which is greater than the thin-walled horizontal part and the lower chord has a wall thickness which is greater than the thin-walled horizontal part. A residual wall is formed by machining the lower chord section and the vertical web over a length area. The residual wall has a residual wall thickness with two planes arranged at right angles to one another over the length area. A T-shaped insert is provided including two legs. A connection device is provided for connecting the two legs of the T-shaped insert to the residual wall portions.
