Abstract

The application relates to roof segments for constructing a roof of a carriage body for a rail vehicle for passenger transport, in particular for use in short-haul operation, such as underground and suburban trains, the rail vehicles or the train units formed by same must be accelerated and decelerated at short intervals. The roof segments are designed in the form of plates, shells or half-shells and consist of an outer wall and an inner wall at a distance to same. At least two roof segments are configured in such a way that the protruding region of the outer wall or inner wall of one roof segment is interlockingly, force-lockingly and/or integrally connected to the non-protruding region of the outer wall or inner wall of the neighbouring roof segment. The roof segments consist at least partially of a fibre-reinforced plastic composite.

First claim

The invention claimed is:

1. Roof segment for the construction of a roof of a coach body for a rail vehicle, wherein
the roof segment is formed plate-, shell- or half-shell-shaped,
the roof segment consists of an outer wall and an inner wall spaced apart therefrom, and the outer wall and inner wall of the roof segments are connected by a middle layer,
the outer wall and the inner wall, at two ends in a longitudinal direction of the coach body, of the roof segment are respectively extended beyond the middle layer or within the middle layer, and at least two roof segments are designed such that the projecting area of the outer wall of the one roof segment is connected to the non-projecting area of the outer wall of the adjacent roof segment and the projecting area of the inner wall of the one roof segment is connected to the non-projecting area of the inner wall of the adjacent roof segment in a positive-locking, friction-locking and/or material-bonded manner, and
the roof segment consists at least partially of fibre-reinforced plastic composite,
the roof segments of a coach body comprise at least two standard-type roof segments, at least two heating-ventilation-air conditioning-type roof segments and two end-type roof segments,
each of the heating-ventilation-air conditioning roof segments comprises slots which are each arranged uniformly in the inner wall, the outer wall and the core material and serve for ventilation,
each of the end-type roof segments comprises slots which are each arranged uniformly in the inner wall, the outer wall and the core material and serve for ventilation.

2. Roof segment according to claim 1 , wherein the fibre-reinforced plastic composite comprises glass, carbon, aramid, basalt, textile and/or natural fibres in a matrix made of thermoplastics or thermosetting plastics.

3. Roof segment according to claim 2 , wherein the thermosetting plastics comprise epoxy resins, unsaturated polyester resins, PU resins, vinyl ester resins or phenolic resins.

4. Roof segment according to claim 3 , wherein the fibres of the fibre-reinforced plastic composite are oriented unidirectionally and/or multiaxially.

5. Roof segment according to claim 3 , wherein the fibres of the fibre-reinforced plastic composite are introduced as rovings, non-woven fabrics, non-crimp fabrics, woven fabrics and/or meshwork.

6. Roof segment according to claim 2 , wherein the thermosetting plastics comprise epoxy resins, unsaturated polyester resins, PU resins, vinyl ester resins or phenolic resins.

7. Roof segment according to claim 2 , wherein the fibres of the fibre-reinforced plastic composite are oriented unidirectionally and/or multiaxially.

8. Roof segment according to claim 2 , wherein the fibres of the fibre-reinforced plastic composite are introduced as rovings, non-woven fabrics, non-crimp fabrics, woven fabrics and/or meshwork.

9. Roof segment according to claim 1 , wherein the fibres of the fibre-reinforced plastic composite are oriented unidirectionally and/or multiaxially.

10. Roof segment according to claim 9 , wherein the fibres of the fibre-reinforced plastic composite are introduced as rovings, non-woven fabrics, non-crimp fabrics, woven fabrics and/or meshwork.

11. Roof segment according to claim 1 , wherein the fibres of the fibre-reinforced plastic composite are introduced as rovings, non-woven fabrics, non-crimp fabrics, woven fabrics and/or meshwork.

12. Roof segment according to claim 1 , wherein the middle layer has a foam core and/or honeycomb core and/or wood core.

13. Roof segment according to claim 1 , wherein the middle layer, as a fibre-reinforced plastic composite which is formed of one or more plies, connects the inner and the outer wall, and formed cavities are filled with foam and/or honeycomb cores and/or wood cores.

14. Roof segment according to claim 1 , wherein the plate-, shell- or half-shell-shaped roof segments are connected to an upper longitudinal beam in a friction- and/or positive-locking and/or material-bonded manner.

15. Use of the roof segments according to claim 1 for the construction of a roof for the coach body of a rail vehicle for transporting passengers for use in underground and suburban railways, in which the rail vehicles or the train units formed of the roof segments are speeded up and slowed down.
