Description

The invention relates to a serving as a base of temporarily installed in the context of tunnel construction measures rails console.

When using railways as part of tunneling, expansion or tunnel renovation, rails are laid which are dismantled once the construction work has been completed. It is important to compensate for unevenness on the tunnel sole. These consist in particular that z. B. in segmental lining a round section of the tunnel profile must be bridged. For this purpose, it is necessary to provide a kind of substructure for the rails and to create a balance, for example, by a wedge-shaped console. As such consoles serve z. B. wooden wedges or structures made of metal. All previously known consoles have in common that they build very expensive and must be adapted to the specific installation conditions on site, which is particularly costly. Wood and steel bring with it the disadvantages of being very difficult to adapt to different local conditions, in particular the tunnel radii. Ie. The material must either be reworked immediately prior to installation or wedges of different shape and inclination must be maintained. An additional disadvantage of the hitherto known wedges is that they are problematic in terms of noise, that it comes as a result of the loads on rails and wedges to damage the surfaces on Tübbingstein or on the concrete sole that track material, locomotives and wagons a particularly are exposed to heavy load and that finally the disassembly at the track dismantling or the replacement of individual sleepers or track yokes is very expensive, see for example DE 198 01 584 A1 ,

Thus, the present invention has the object to provide a serving as a support of temporarily installed rails for rail transport console, which is adapted to overcome the aforementioned disadvantages.

This object is achieved in that the console rests with its underside on the tunnel sole and has a below the rail to be positioned plateau with uneven thickness and pairwise oppositely arranged arms.

The console is positioned below the rails as part of the installation, where it forms a particularly suitable support for the rails. In addition to the below the rail and serving as a real support plateau, the console has pairs of oppositely arranged arms. In a particularly suitable manner, the console according to the invention adapts on the one hand rail or threshold and on the other hand, the tunnel sole. To adapt the console according to the invention to the conditions on site, it is provided that the plateau has an uneven thickness. For this purpose, the underside of the console can be arranged linearly inclined or even running around. In any case, the console, if made of a resilient material, can also adapt well to local conditions.

In addition, it is provided that the arms comprise the foot of the rail and / or the rail sleeper. Thus, the module consisting of bracket or rail and / or threshold is given an additional degree of stability by the console serves not only as a support, but beyond also to stabilize rail and / or threshold from above and to create contact surfaces.

A preferred variant of the invention provides that the console has at least two arms arranged in pairs. Total at least four arms so that the console or the plateau evenly and on both sides of rail or threshold.

In this sense, the proposal is to be understood, according to which the arms are provided on the outside of the plateau. Preferably, they are positioned in the four corners of the plateau or console and extend upwardly out of the plane of the plateau.

In order to produce an even better connection between the arms of the console and rail or threshold, it is advantageous if the arms are resilient and / or stored, so that there is a kind of snap or click connection between the console and rail and / or Threshold can come. Thus, a very simple mounting of console and rail is possible by the arms, so to speak automatically after installation rail foot or threshold enclose and virtually position themselves.

In addition, it is provided that the arms are formed and arranged at its upper end corresponding to the rail foot and / or the rail sleeper. This ensures that the arms may also partially include rail foot or threshold so that it comes to the intended, particularly suitable connection. This is also advantageous in that a noise-damping device is realized by the close contact between the console and rail. In addition to the narrow and large-area contact between rail and console, this is also ensured by the choice of a correspondingly resilient and noise-damping material for the console.

The corresponding design of the arms to the rail foot and / or threshold is achieved when the arms have on their upper side an inwardly directed projection, which applies with its underside to rail foot or threshold.

In a modification of the variant described in which the arms are perpendicular from the plateau uplifting on the side, another solution provides that the arms are provided on the outside of the actual console. There, the arms extend to the side, ie parallel to the ground.

A variant of the invention provides that the console has on one side a pair of arms and on the opposite side a corresponding to the rail formed and upwardly extending end strip. This variant proves to be in addition to the four arms in the corners of the plateau to the effect that the surface pressure is lower. In this respect, so to speak, two arms on one side of the console are complemented or replaced by the corresponding trained to the rail and positioned on the opposite side of the console end bar for better distribution of the forces occurring.

In particular, it is envisaged that the end strip at its ends in transversely to its longitudinal axis arranged, arranged on the outside of the plateau webs merges. A kind of ramp-like transition extends to this end of the end strip in its transverse direction to the webs, which in turn form a kind of connection to the oppositely positioned arms. The end bar can also serve the function of a partial enclosure for rail or rail sleeper. It serves to the sides, as well as partly upwards by their corresponding training as their additional guidance.

It is also envisaged that the pairs of oppositely arranged arms or arms and end strip can be connected to each other with a tension belt. By means of this tension belt, it is achieved that corresponding contact surfaces exist between the console on the one hand and the rail or the threshold, on the other hand. In the embodiment of the invention with two pairs of oppositely arranged arms each such arms are positioned with straps in the region of the ends of the console.

Another proposal provides that the plateau has a frame formed corresponding to a rail tie. This frame is preferably formed by webs arranged on two longitudinal sides and one end face and can thus serve as a border of a rail sleeper.

An additional embodiment provides that the plateau has at least one step on its upper side. Appropriately, on the opposite sides of the plateau such, extending on the inside of the click arms grading is provided so that there forms a kind of well-sleeper bed. The primary purpose of these gradations is to absorb the dynamic forces associated with driving the trains, in particular the braking forces.

It is recommended that the console be made in one piece, which is advantageous in several aspects. Thus, for example, the assembly of the consoles below the tracks or sleepers is particularly easy, especially since no tools are necessary for this purpose. Likewise, separate fasteners are unnecessary. Furthermore, this one-piece design of the console proves to be advantageous in terms of noise reduction, the possibility of disassembly or replacement or low wear.

It has already been pointed out that a certain flexibility for the console is appropriate. This refers on the one hand to the underside of the console and the adaptation to the tunnel sole, in particular the tunnel radius and on the other hand on the top and the adaptation to rail and / or threshold and the snap or click connection through the arms. It is therefore recommended that the console be made of plastic or rubber, in particular the Shore hardness 80 A for plastic or the Shore hardness 40 D for rubber.

In order to achieve a better connection between the console and resting steel sleeper, it is provided that the console has an adhesive surface on its upper side. The adhesive layer on the top of the console additionally fixes it on the tunnel sole. Due to the above-described frame-like design of the contact surface between the console and rail sleeper forming plateau, this adhesive surface is additionally only relatively low mechanical load, so that they can develop their full effect.

The invention is characterized in particular by the fact that a serving as a base of temporarily installed rails for rail transport console is created, their use is useful in the context of tunnel construction measures. The compactness of the consisting of a plateau and the pairs arranged opposite two, four or more arms console and their connection to rail and / or threshold gives the system special advantages such as noise reduction, exact adaptation to the tunnel radius, the absence of surface damage to the tubbing stone or the concrete base, longer life of the rolling stock in the form of locomotives and wagons by damping the shocks and vibrations and associated lower maintenance costs, easy and quick installation in the factory or on the tunnel construction site, reusability, protection of the track material, easy dismantling at track dismantling or simple change derailment of individual sleepers or track bumps as well as a full-surface discharge of the resulting braking forces through the grooved sleeper bed of the console and a flexible material with regard to flammability or the avoidance of En formation of soot particles.

In FIG. 1 a track 31 is shown in section. This consists of the two rails 3 and 3 'together with the console 1, 1' positioned underneath. The rails 3, 3 'have a head 24, 24', a web 25, 25 'and a foot 4, 4'. The latter is comprised of the console 1, 1 'positioned under the rail 3, 3' on its upper side. Fasteners 32, 32 ', 33, 33' serve to fix the rails 3, 3 '. The reference numeral 34 denotes the tunnel radius, the z. B. is specified by the tubbing and must be compensated by the consoles 1, 1 '. For this reason, the brackets 1, 1 'have an uneven thickness in the area of the plateaus 2, 2' serving as the actual base.

This is also especially good in FIG. 2 to recognize. The thickness of the plateau 2, 2 'increases from the outside 35 to the outside 36 in order to achieve a corresponding adaptation to the tunnel construction. In the four corners of console 1 or plateau 2 each extend arms 6, 7, 8, 9. These have at their upper ends 13, 14, 15, 16 projections 17, 18, 19, 20, which inward, ie where, rail foot and / or threshold to include extend. In conjunction with the resilient design of these arms 6, 7, 8, 9 and their corresponding training on the rail and / or threshold so that a kind locking or click connection is realized. On the upper side 21 and there on the outer sides 11, 12, the plateau 2 has gradations 22, 23. This is a full-scale discharge of the resulting braking forces can be achieved by this sown threshold bed.

Again shown is the console 1 in FIG. 3 , this time in side view. Good to see is the corresponding formation of plateau 2 and the arms 6, 7 shown here with the projections 17, 18 on their upper sides 13, 14 with respect to the rail foot, not shown here, and the increasing thickness between the sides 35 and 36th and the associated good adaptation to tunnel radii and other irregularities in the area of the tunnel sole.

In the installed state shows FIG. 4 the console according to the invention 1. This rests with its underside 37 on the tunnel sole not shown here and comprises by means of the arms 6, 7, more precisely, the projections 17, 18 of the foot 4 of the rail 3 in a kind of click connection. To fix the rail 3 are the clamping plates 26, 29 with the welding studs 38, 39 and the nuts 28, 30. The reference numerals 40, 41 are springs, with the reference numeral 27 is provided the net hook. Obviously, just in the presentation according to FIG. 4 the compactness of the console 1, inter alia, by the large-area contact between foot 4 of the rail 3 and the console 1 or the click connection, even if one compares this with the previously known solutions in which wedges were positioned exclusively below the consoles.

In plan view shows rail 3 and console 1 FIG. 5 , The rail 3 rests on the rail sleeper 5 and is connected via welding bolts 38, 39 and nuts 28, respectively. 30 fixed with the rail chairs 29. Before and behind the threshold 5, the four arms 6, 7, 8, 9 of the console 1 can be seen.

Also shows FIG. 6 the ensemble of rail 3 and console 1 in side view. The foot 4 of the rail 3 is encompassed by the here recognizable arms 6 and 8. About the rail chair 29 and bolt 39 and nut 30 rail 3 and 5 threshold are fixed together.

FIG. 7 shows a console 1 in side view, the thickness of which increases greatly from page 35 to page 36. With the bottom 37 it rests on the tunnel sole, not shown here. It is in the representation according to FIG. 7 to the variant of the invention with only a pair of opposing arms, of which here the arm provided with the reference numeral 7 conceals the underlying.

In bottom view, this console is 1 in FIG. 8 shown. About the adhesive layer or adhesive surface 47 on the top 21 of this console 1, the steel sleeper, not shown here is additionally fixed and framed by the webs 24, 49 and 50.

In FIG. 9 Above all, the frame-like formation around the plateau 2 is illustrated. On the outside of the plateau 2 around the adhesive surface 47 around are two webs 48, 49 on the longitudinal sides 51, 52 and a third web 50 on the end face 53. These webs 48, 49, 50 together form the frame 46, whereby console 1 or plateau 2 are formed corresponding to a rail sleeper and serve to quasi their inclusion.

The variant of the console 1 with only a pair of oppositely positioned arms shows FIG. 10 , Only the arm 7 or by this hidden arm is present and serves to surround the foot 4 of the rail 3. This is otherwise fixed by the clamping plates 26, 29 with the welding studs 38, 39 and the nuts 28, 30. A Liner 54 off Plastic is still below the foot 4 of the rail 3 and thus between rail 4 and console. 1

According to FIG. 11 the arms are located laterally on the console 1. In this illustration, the arms 7 and 8 on the outer side 43 of the console 1 can be seen. They are perpendicular to the ground from the outside 43.

This is also in FIG. 12 shown. The arms 7 and 8 on the outside 43 and the arms 6 and 9 on the outside 42 are positioned so that the tension belt can be fastened between them. Well recognizable here is again the frame 46, consisting of the webs 48, 49 and 50.

The top view in FIG. 13 then shows the tension belt 44 installed on the arms 6 and 7. To better fix the tension belt 44 on the arms 6, 7, these have a chamfer 55, 56 and a thickening 57, 58, behind which the tension belt 44 can engage.

Finally shows FIG. 14 this variant of the console 1 in a perspective view. The arms 8 and 9 are of the tension belt 45, the arms 6 and 7 spanned by the tension belt 44, so that resting on the plateau 2, but not shown here threshold between the webs 48, 49, 50 positioned and in addition of the tension straps 44th and 45 is included safely.

In FIG. 15 a variant of the invention is shown, which is characterized in particular by the end strip 10, which replaces as a variant two arranged in the respective corners of the plateau arms. This solution is considered to be advantageous in that the surface pressure can be reduced by the compact design of the end strip 10. This also becomes clear when looking at the presentation FIG. 15 for example with the in FIG. 2 compares. The end strip 10 is positioned opposite the arms 7 and 9 and extends here over the complete outer side 35 of the console 2. Transverse to one of its longitudinal axes 63 are located at the ends 61, 62 of the end strip 10th ramp-like transitions 64, 65 in the webs 48, 49, which in turn form a kind of connection to the oppositely positioned arms 7 and 9. The end strip 10 is arranged by the ramp-like transitions 64, 65 and / or by the receptacle 66, which forms them for the rail or rail tie, not shown here, corresponding to the latter.

In FIG. 16 the console 1 is shown with the end strip 10 in side view. The end strip 10 is in the frame 48 in the context of the ramp-like transition 64. Thus, the end strip 10 forms with the opposite arms 18 together the receptacle for the rail or railroad tie, not shown here.
