the structural wall type flag 20 or lower floor 10 ensures mechanical reliability of the body 4 because this structural wall assembles the first 26 and the second part 28 by means of the interface piece 58 ensuring the preservation of the mechanical properties of composite materials during welding or riveting steps.
the interface piece 58 and the outer layer 38 are joined together, for example welded or riveted to one another.
the sleepers 40 are then fixed against the inner face 48 of the outer layer, for example by gluing or heat-sealing in the case of use of thermoplastic composite sleepers.
the covering element 42 is integrated in the useful volumes 50 defined between the crosspieces 40.
the second part 28 is then connected to the first part 26, for example by welding or riveting.
the interface piece 58 is advantageously cooled by forced convection or by any other equipment for cooling the interface piece 58.
the forced convection is performed by circulating a flow of fresh air into the closed volume 74 of the interface piece 58.
the method of assembling the structural element 10, 20 avoids any damage to the composite parts by ensuring a controlled heat flow during welding. Any overheating of the composite materials is guaranteed by a sufficient spacing between the zone to be welded and the composite parts or by forced convection cooling by a flow of fresh air in the dedicated volume 74.
the structural wall type flag 20 or lower floor 10 is adapted to a box 4 of railway vehicle 1 to a floor.
