Rail vehicle door

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.

Claims

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.

DETAILED DESCRIPTION OF THE INVENTION

(5) FIG. 1 shows the rail vehicle door 10 according to the invention in a perspective view and in a plan view in sectional illustration.

(6) Four profiles 11 are connected to one another at their respective corners and form a frame-type door basic body 12 which is used as a carrying structure.

(7) Covering metal sheets 15, 16 are arranged on two opposite sides 13, 14 of the door basic body 12 and are connected to the door basic body 12 or to its profiles 11.

(8) The rail vehicle door 10 has a peripheral edge 17 along which there is arranged a material 18 which foams in the event of a fire, in particular an intumescent material. This prevents smoke passage into spaces which adjoin the rail vehicle door 10.

(9) Empty spaces 20 of the frame-type door basic body 12 are filled with fire protection material 19.

(10) The fire protection material 19 used is preferably gypsum board.

(11) FIG. 2 shows an illustration of individual elements of the rail vehicle door 10 according to the invention.

(12) There can be seen here three of the profiles 11 which are connected to one another at their corners by way of special corner connectors (cf. in this respect the following figures) and without using welding techniques.

(13) The profile 11 used is preferably a market-standard and thus cost-effective rectangular hollow profile.

(14) The frame-type door basic body 12 includes stiffening transverse struts 21 which are preferably arranged offset from one another in such a way that any heat conduction between the transverse struts 21 is reduced and thus the thermal insulation of the rail vehicle door is increased.

(15) Empty spaces 20 of the frame-type door basic body 12 can additionally be filled with fire protection material 19 (not shown here).

(16) Fire protection material 19, preferably in strip form, is arranged between at least one covering metal sheet 15, 16 and the frame-type door basic body 12.

(17) The fire protection material 19 used is preferably gypsum board.

(18) The large-area arrangement of the fire protection material 19 achieved thereby improves the fire resistance of the rail vehicle door 10 and its thermal insulation.

(19) FIG. 3 shows, with reference to FIG. 1 and FIG. 2, a detail of the rail vehicle door 10 according to the invention in cross section.

(20) FIG. 4 shows, with reference to FIG. 1 and FIG. 2, a detail of the rail vehicle door 10 according to the invention in cross section.

(21) It can be seen here how two profiles 11 are connected to one another exclusively by way of a fixed, but releasable connection by way of an associated, respective corner connector 22.

(22) The corner connector 22 is preferably manufactured from one or more metal sheets or optionally as a casting and connects the two profiles 11 by means of a preferably cost-effective rivet connection or other releasable connection.

(23) The corner connector 22 is preferably cut into shape by means of a laser and therefore has only minimum tolerances.
