Manufacturing method for steel flexure beam e.g. for high-speed train track carrier or bridge structure, has pre-stressed base profile combined with plate for completing beam cross-sectional profile

摘要

The manufacturing method for a steel beam, as in DE10214824.4, has a base profile (4,101), manufactured during an initial manufacturing step and pre-stressed in dependence on the maximum flexure moment at the designed loading, combined with a steel plate (5) for completing the beam cross-sectional profile in a second manufacturing step, with subsequent removal of the bias device for pre-stressing the base profile. Also included are Independent claims for the following: (a) a flexure beam; (b) a device for fabrication of a flexure beam; (c) a method and flexure beam construction for manufacture of pre-fabricated load supports; (d) a load carrying structure for a bridge
