Abstract

A door for rail vehicle has a frame-type door main body and covering metal sheets. The door main body is formed of profiled elements, which are connected to each other by way of corner connectors. The covering metal sheets are arranged on two opposite sides of the door main body. The profiled elements are connected to each other exclusively by way of a fixed but releasable connection by the corner connectors. A fire protection material is arranged between at least one covering metal sheet and the frame-type door main body in such a way that the fire resistance and the thermal insulation of the rail vehicle door are increased.

First claim

The invention claimed is:

1. A rail vehicle door, comprising:
a frame forming a door basic body, said door basic body being formed of profiles that are connected to one another by way of corner connectors;
said door basic body formed of said frame further including a plurality of stiffening transverse struts offset from one another in a direction defining a thickness of the door;
covering metal sheets disposed on two opposite sides of said door basic body;
said profiles being connected to one another exclusively by way of a fixed, but releasable connection by respective said corner connectors, each of said corner connectors being flat; and
fire protection material arranged between at least one of said covering metal sheets and said door basic body for increasing a fire resistance and a thermal insulation of the rail vehicle door;
said fire protection material being gypsum board arranged areally over a large area between said covering metal sheet and said door basic body.

2. The rail vehicle door according to claim 1 , wherein said corner connectors are manufactured from metal sheets.

3. The rail vehicle door according to claim 2 , wherein said corner connectors are laser-cut shapes of metal sheets.

4. The rail vehicle door according to claim 1 , wherein said fixed, but releasable connection configured to connect said profiles and said corner connectors is a rivet connection or a screw connection.

5. The rail vehicle door according to claim 1 , wherein empty spaces of said door basic body are filled with said fire protection material.

6. The rail vehicle door according to claim 1 , further comprising a material which foams in the event of a fire arranged along a peripheral edge of the door.

7. The rail vehicle door according to claim 6 , wherein said material which foams in the event of a fire is an intumescent material.

8. The rail vehicle door according to claim 1 , wherein said profile is a rectangular hollow profile.

9. The rail vehicle door according to claim 1 , wherein said at least one covering metal sheet is connected to said door basic body by way of said fire protection material.
