Casting is effected with a mould device, which incorporates mould surface components, extending in the beam longitudinal direction and forming the mould hollow space. At least one mould surface component for limiting a side of the beam turned away from the bridge or similar is retained directly or indirectly with a number of primary cross supports. The cross supports incorporate a column and preferably a force-transmitting stay part which extends between the column and underlay parts. The column and the underlay parts are joined to one another at one end of the parts, rigidly or preferably rotatably in relation to one another in a plane in which these parts are located and in an angle range between these parts. The parts are fastenable or lockable at a specific reciprocal angle during casting, preferably with the stay part, which is connected to them at a distance from their joining point. |
