A METHOD FOR MANUFACTURING BOX GIRDER, A BOX GIRDER AND A CONSTRUCTIONAL PART THEREFOR

摘要

The invention relates to a method for manufacturing an elongated box girder assembled with a solid joint (100) from at least two separate prefabricated structural components. The method comprisestaking at least one structural component (3) having at least one border area (11) and taking at least one second structural component (4), the plate having a second or a third thickness. The border area is shaped by shifting the edge of the first plate laterally in a direction perpendicular to the plate surface (10) over a distance equalling the thickness of the second plate to form a support surface (30) parallel with the surface of the finished structural profile at the joint of the structural components. Said structural components are joined with said border area overlapping with the second structural component to be joined at the joint ofthe structural components, the overall outer surface of the structural profiles being substantially planar at the joint between the structural components.
