DESCRIPTION OF THE INVENTION

(8) FIG. 1 shows a heavy-duty T-rail 1 which is part of a fastening arrangement for an equipment container which is intended to be fitted to the roof of a rail vehicle. Such equipment containers may, for example, contain an air-conditioning system or a brake resistor.

(9) The T-rail 1 has a web 2 which in the assembled state of the T-rail extends vertically and is connected with the free end thereof to a profile-member of the roof of the rail vehicle. In particular, the T-rail 1 can already be pressed by means of the web 2 when, for example, an extruded aluminum profile-member is produced for the roof of the rail vehicle.

(10) In addition to the web 2, the T-rail 1 has a support plate 3 which forms a structural unit with the web 2. The support plate 3 has a hole 4 which extends completely through the support plate 3 and into the web 2 over a distance which is greater than half the height of the web 2. Consequently, the T-rail 1 can be protected against corrosion not only from the outer side, but also on the inner faces of the hole 4 using conventional methods, for example, by applying an appropriate layer of paint, with priming beforehand.

(11) In the embodiment illustrated, the T-rail is produced from aluminum and provided for use in a rail vehicle which is produced with an integral aluminum construction.

(12) However, a clamping device 5 which in the fastening arrangement cooperates with the T-rail in order to fasten a retention portion 6 of an equipment container (not illustrated) primarily comprises steel.

(13) A clamping screw 7 which clamps the retention portion 6 with a washer 8 being interposed belongs to the clamping device 5. As can be seen from FIG. 3, the retention portion 6 is in this instance retained by means of a bush 9 with spacing from the upper side of the support plate 3. The clamping screw 7 is screwed into an axial thread of a counter-bearing 10.

(14) FIG. 3 shows the securing arrangement from the side. In the region of the hole 4, there is provided below the support plate 3 a plate-like counter-bearing 10 which extends in the direction of the web 2 over the diameter of the hole 4. In contrast, the bush 9 above the support plate 3 has a larger diameter than the hole 4 so that the bush 9 is positioned in this region on the support plate 3.

(15) As can be seen from FIG. 4, the bush 9 is constructed as a rubber/metal element. At the upper side thereof, it has in a radial direction a graduation so that the retention portion 6 which is provided with an opening can move into abutment with the bush 9. In this instance, the height of the step is slightly smaller than the thickness of the retention portion 6. Whilst the portion of the bush 9 which extends around the clamping screw 7 and the portion which is located below the retention portion 6 are produced from steel and form an inner bush portion 11, the outer periphery of the bush portion 11 is adjoined by a rubber element 12 which extends along the support faces of the bush 9 with the support plate 3 and also surrounds the portion of the bush 9 which forms the support face for the retention element 6. Consequently, the outer face of the rubber element 12 extends from the upper side of the support plate 3 as far as the lower side of the retention element 6. On the whole, the bush 9 terminates with the lower side thereof with the lower side of the support plate 3. The bush 9 is generally constructed in a cylinder-symmetrical manner and inserted into the hole 4.

(16) At a lower side of the support plate 3 there is arranged the counter-bearing 10 which is also in the form of a rubber/metal element. An inner counter-bearing portion 14 which is associated with the clamping screw 7 is produced from steel and engages in the bush from below in an annular recess 13 at the inner side of the bush 9 so that the counter-bearing 10 is centered with the bush 9. A portion 15 of the counter-bearing 10 facing the support plate 3 is produced from rubber and extends along an abutment face of the counter-bearing 10 with the support plate 3 and further inwards from an inner edge of the support plate 3 so that the portion 15 is connected to the rubber element 12 in such a manner that these two rubber elements 12, 15 engage round the support plate 3 and seal both the inner bush portion 11 and the inner counter-bearing portion 14 which comprise steel with respect to the support plate 3 of aluminum so that corrosion is prevented.

(17) From FIG. 5, it can be seen that the longitudinal extent of the T-rail 1 corresponds to at least three times the diameter of the hole 4. This ensures adequate introduction of force from the equipment container via the retention portion and the fastening arrangement into the roof profile-member and primarily over the remaining length portions of the web 2 over the full height, that is to say, outside the hole 4.

(18) From FIG. 6, it can be seen that the counter-bearing 10 maintains a spacing with respect to the web 2 in the region of the hole 4 and consequently extends in the direction of the web 2 to a lesser extent than in the transverse direction with respect to the web 2. The counter-bearing 10 additionally has a suitable thread in which the clamping screw 7 can be screwed, whereby the retention portion 6 is clamped and consequently fixed.
