PROCESS AND APPARATUS FOR PRODUCING A BOX GIRDER OR U- SHAPED TRUSSED GIRDER

摘要

A process for producing a box girder or U-shaped trussed girder, in the case of which, at a first assembly station 6, at least in the case of a load-bearing part 3, of which the two side framework arrangements 3a, b are produced in the horizontal position on tilt-up panels 7a, b which can be pivoted with respect to one another, there follows an operation in which the tilt-up panels 7a, b are pivoted with respect to one another, together with the side framework arrangements 3a, b secured on them, into a position which corresponds to the definitive position of the two side framework arrangements 3a, b relative to one another, the two side framework arrangements, in this position, are connected to one another via the connecting pieces 3c, the finished load- bearing part 3 is released from the tilt-up panels 7a, b and brought to a second assembly station 16, and at the second assembly station 16 the finished load-bearing part 3 is brought into the definitive position relative to a further load-bearing part 2, produced from two side framework arrangements and connecting pieces, and is aligned in relation to the further load-bearing part 2, it being the case that, during the aligning operation, at least one load-bearing part 3 is supported in a vertically movable manner and the side framework arrangements 2a, b; 3a, b of the two load-bearing parts 2, 3 are connected, in particular welded, to one another at their abutment locations.
