DETAILED DESCRIPTION
(53) As shown in
(54) The rail chambers are filled out in the illustrated embodiment with custom-fit filler block elements 22. The intermediate rail mouldings 20 rest on the respective filler block elements 20 with their narrow sides 20a facing the rails 2, 2′ (see
(55)
(56) As from the sectional view in
(57) Through the cross bores 26 the fastening bolts 27 extend perpendicular to the rail direction. The fastening bolts 27 are firmly tightened in the assembled state in horizontal threaded inserts 28 (see also
(58) In the illustrated embodiment, under the bolt heads, metallic support block 40 (see also
(59) At the support blocks 40, the track outer-side mouldings 30, 32 can be indirectly locked to the fastening bolts 27. To this end, securing bars 44 extend longitudinally along the railway track through the support block longitudinal bores 42, as is obvious in
(60) As shown in
(61) However, other versions are possible. Thus, the cross bores 26 can extend, for example, through the middle or upper region of the rail webs 8 and the securing bars 44 below the fastening bolts 27. In this case, securing of the track outer-side mouldings 30, 32 directly to the fastening bolts 27 is facilitated, for example, without a support block 40, for example, in which the securing bars 44 engage under and/or behind the bolt head.
(62) The partially constructed railway crossing, as illustrated in
(63) In the next step, the similar, intermediate rails mouldings 20 (of the third group) are placed between the two rails 2, 2′, in which, for example, the latter are raised at the openings 23 with ropes or equivalent and lowered between the rails 2, 2′. The intermediate rail mouldings 20 are thereby placed between the rails 2, 2′ such that the threaded inserts 28 located on the narrow sides 20a are covered with the cross bores 26 and that the two mouldings 20 lie adjacent to each other along the rails 2, 2′.
(64) For each of the cross bores 26 the following process is followed: a support block 40 is mounted on the outer filler block element 22, so that its support block—cross bore 41 coincides with the transverse channel 220 of the filler block element 22. Then, the respective fastening bolt 27 is inserted through the support block—cross bore 41, through the transverse channel 220 of the outer filler block element, through the cross bore 26 in the rail web 8 and through the transverse channel 220 of the inner filler block element into the threaded insert 28 of the intermediate rail-moulding 20 and the intermediate-rail moulding is secured tightly and simultaneously the support block 40 is braced on the outer filler block element.
(65) In the next step similar track outer-side mouldings 32 (the second group) are placed adjacent to the outer side of the second rail 2′ so that the mouldings 32 lie adjacent to one another side by side along the rails 2′ and longitudinal channel 34 faces the rail 2′ running in these mouldings and extends longitudinally along the rail 2′ (in
(66) Finally, in an analogous manner, similar track outer-side mouldings 30 (of the first group) are placed adjacent to the outer side of the first rail 2 (shown in
(67) A built-up railroad crossing can be dismantled again in a simple manner. In the illustrated embodiment of
(68) As indicated in
(69) The recesses do not extend continuously along the width of the moulding 20, for example, along the rail in the installed state. Between the recesses, the moulding 20 extends, in the installed state, integrally on the rail foot 4 and is supported thereon.
(70) In the narrow sides 20a facing the rail each have a horizontal receiving device 21, in particular, set up as a channel for a fastening means 27 and/or a threaded insert. Especially with elastomeric mouldings threaded inserts are factory set in the receiving devices 21. The threaded inserts can, for example, be bolted into the receiving devices 21 or can be formed already during production in the mouldings (see also
(71) The width of a moulding 20b corresponds to the distance between the two end faces. Through the width of the intermediate-rail moulding 20 the openings 23 located can extend, to which the mouldings 20 can be for example, fastened with ropes or chains, in order to lift it. Within the openings 23, a hollow tube 25 can be surrounded, as can be seen in
(72) As indicated in
(73) The moulding 30 has, on its underside, recesses 39 for the rail-foot fixing equipment and a recess 37 for the support block 40 and the fastening bolt 27 (see also
(74) Further, a longitudinal channel 34 extends through the track outer-side moulding 30, in which the safety bar 44 is inserted in order to lock the track outer-side moulding 30 to the support block 40.
(75)
(76) The side 22c, facing away from the rail, is essentially straight and faces the respective intermediate-rail moulding 20 or track outer-side mouldings 30 and 32 respectively. The side 22c, facing away from the rail, of a built-in filler block element 22 extends substantially flush with the side face of the rail head 6. The side 22c, facing away from the rail, also has recesses 221 for the support blocks 40. If more than one filler block element is used for a rail chamber, these abut with their end faces 22b to one another to form a continuous web.
(77) In the present example, the filler block element 22, as shown, is longer than the mouldings and has in particular a length corresponding to the width of two mouldings 20 arranged longitudinally along the rail side by side. Accordingly, the filler block element 22 has a plurality, here two transverse channels 220 for fastening bolts 27.
(78)
(79) As can be seen from
(80) A support block 40, designed as a rectangular solid with two plane-parallel and side surfaces 40a running perpendicular in assembled condition, is preferred since a track outer-side moulding 30 can be passed with a cuboid-shaped recess 37 for mounting from the top at the support block 40 and is finally locked in the installed state with the corresponding inner sides of the recess 37 to the support block 40 in both directions along the rail. In the longitudinal direction of the rail, the recess 37 of the track outer-side moulding 37 is accordingly set up custom-fit to the length of the support block 40, defined by the distance of the two side surfaces 40a.
(81)
(82) In this embodiment, the rail chambers on the inner sides and/or outer sides 3, 3′ of the rails are respectively filled-out with different filler block elements 22′ and 22″ (see also
(83) Just as in the embodiment of
(84) As can be seen in
(85) In this embodiment, in the installed state by means of the fastening bolts 27, L-shaped brackets 50 (see also
(86) Referring to
(87) Referring to
(88) Further, one or more vertical bores 35 extend, in the example shown four pieces, through the track outer-side mouldings 32′ in order to bolt the mouldings at the fixing bracket 50.
(89)
(90) As can be seen from this example that rail facing sides 22a′, 22a″ of filler block elements 22′, 22″, rounded, can be designed custom-fit for the rail chamber, or polygonal approximated to the shape of the rail chamber. The track-remote sides 22c′, 22c″ are turned to the respective intermediate-rail mouldings or track outer-side mouldings and in both cases substantially straight.
(91) The filler block element 22′ for the inner sides of the rails is configured so wide that it protrudes sufficiently far from the rail chamber, in order to form the track groove 24 adjacent to the rail head 6. Because of its greater width, the filler block element 22′ has further recesses 229 for rail-foot fixing securing device.
(92) Referring to
(93) Referring to
(94) Transverse to the track direction, a track configured as a pair of rails track can therefore be made passable through three plates, namely a first track outer-side moulding 30 adjacent to the traffic area 60, an intermediate rail moulding 20 and a second track outer-side mouldings 32 adjoining the traffic area 60.
(95) The track outer-side mouldings 30, 32 are closed, in particular, to their track-remote narrow side on the asphalt of the traffic area 60 cutting across the rail network. The surface of the level crossing body set up by the moulding is essentially of same height to the traffic area 60 intersecting the area, so that the road users can easily pass through the level crossing.
(96) Referring to
(97) Referring to
(98) The track outer-side mouldings 30 are not clamped along the rail to one another but are each independently locked with their recesses 37 to the support blocks 40 against any displacement along the rail. The same applies to the track outer-side mouldings 32. The intermediate rail mouldings 20 are also not clamped to one another, but in each case independently fastened with fastening bolts 27 to the rails 2, 2′.
(99) Referring to
(100) Because the curves of the rail chamber can be different, a narrow spacing web 43 is specially suited to a support block 40. In this way, the spacer web 43 fits closely with only a small area and approximately centrally with respect to the height of the rail on the essentially straight centre piece of the rail web 8.
(101) Referring to
(102) Referring to
(103) Referring to
(104)
(105) The mouldings, which are adjacent to each one of the outer sides of the two rails 2, 2′, are each fixed to a rail by means of a moulding holder 80, while the moulding which is located between the two rails 2, 2′, and is fixed on both rails 2, 2′ by means of a respective moulding holder 80. An operation of the mouldings in the rail chamber is therefore not required. The fixing of a moulding to the rail 2, 2′ by means of a moulding holder 80 or by means of a cross bore 26 (as described above) is safer and more stable than a fixing by the operation of the moulding in the rail chamber and also facilitates the assembly because the moulding does not need to be arranged in the rail chamber.
(106) In order to build a railroad crossing having a sufficient width, several mouldings are usually arranged side by side along the track section, whereby often, as already described above, three groups of mouldings are laid. A plurality of moulding holders 80 can be fixed in a regular interval along the respective rail 2, 2′, in order to fix the groups of mouldings thereon. In this case, the moulding holders 80 are located at an appropriate rail 2 at the same positions along the track direction like the moulding holders 80 at the other rail 2′.
(107) In the Figures as shown, at least one moulding holder 80 is provided for a moulding in each case. However, a plurality of mouldings (for example, mouldings of a group) adjacently disposed in the track direction can be fixed together at a moulding holder 80. This helps to reduce the number of moulding holders 80.
(108) The preferably metallic moulding holders 80 can be retrofitted to an existing track grid with sleepers 14 and attached to secured rails 2, 2′ so as to set up a railroad crossing over the track grid. As illustrated, the moulding holders 80 are preferably secured between the sleepers 14 and/or between the rail-foot fixing devices 10, 12 at the rails 2, 2′. Thus, the mouldings can be fixed by means of the moulding holders 80 directly onto the rails 2, 2′. This allows a particularly secure and stable fixing of the bodies at the track grid, particularly in the area close to the track. The locking of a moulding at a moulding holder 80 can be accordingly carried out as described above in connection with a support block 40. The above designs similarly apply to the moulding holder 80.
(109) A moulding can accordingly be locked to the associated moulding holder 80 having a safety bar 44, and thus secured against a lift out upwards and against lateral removal away from the rail. In the locked state, the safety bar 44 extends longitudinally along the track section through a longitudinal bore 42′ in the moulding holder 80. The safety bar 44 also extends longitudinally along the track section through a longitudinal channel in the mouldings so that the moulding at the moulding holder 80 is fixed.
(110) Referring to
(111) The holding clamps 82, 82′ each have a rail-foot base grip section 84, 84′, which rests on the underside of the rail foot. 4 The holding clamps 82, 82′ of a moulding holder 80 are clamped together by means of a clamping bolt 86. For this purpose, the holding clamps 82, 82′ each have a tensioning bolt guide 88, 88′, wherein the clamping bolt 86 extends together through the clamping bolt guides 88, 88′ of both holding clamps 82, 82′. The clamping bolt guides 88, 88′ and the clamping bolt 86 pass beneath the rail foot 4. In the example shown, the clamping bolt guides 88, 88′ are arranged respectively on the rail-foot base grip section 84, 84′. The clamping bolt 86 has two threaded ends 86a and 86b, on each of which a clamping nut 90, 90′ is bolted, in order to brace the holding clamps 82, 82′ with each other and against the rail foot 4. In the braced state, the rail foot 4 is therefore clamped between the two holding clamps 82, 82′ of a moulding holder 80, similar to a clamp.
(112) In a further embodiment not shown, the opposed holding clamps 82, 82′ of a moulding holder 80 can be clamped with each other on the rail through a cross bore 26. According to the same principle, two support blocks 40 can be bolted to a rail through a cross bore 26 in juxtaposition to each other.
(113) For all embodiments, it is preferably provided such that a moulding, for example, an intermediate rail moulding 20, 20′, a track outer-side mouldings 30, 32, 30′, 32′, a base plate moulding 18, or a cover plate moulding 19, has a certain minimum thickness in the vertical direction with regard to the built-in state. This ensures a sufficient stability of the level crossing and/or of the individual mouldings, particularly in mouldings made of rubber-elastic material, in particular bonded rubber granulate or vulcanized rubber. Accordingly, at least in the major part of its horizontal extent, a moulding has a thickness, which corresponds to at least half, preferably at least to the entire height of the rail head, for example, at least 25 mm or at least 50 mm. Specifically, one or more mouldings 20, 20′, 30, 32, 30′, 32′, 18, 19 consist of not only a thin rigid metal plate with securing blocks, flange-mounted on the sides.
(114) Both the top plate mouldings 19 and the base plate mouldings 18 consist of an elastomer or an elastomer blend, and preferably each have a mass of less than 100 kg, preferably less than 90 kg, more preferably less than 85 kg.
(115) The base plate mouldings 18 have, in the direction of the track, an extension that corresponds to the threshold distance, so that they can lie along the track direction on two adjacent sleepers 14 side by side. The base plates mouldings 18 are thus arranged in the direction of the track arranged according to a base plate grid, which is determined by the threshold distance. The cover plates moulding 19, in contrast, can be arranged in accordance with a deviating or offset cover plate grid in the track direction. In the example shown, the cover plate mouldings 19 each are laid offset relative to the base plate mouldings, wherein for the mouldings lying between the rails, the top plate grid is offset against the base plate grid by half a sleeper spacing. Generally, the grid spacing can differ, in this example, the cover plates mouldings 19, lying outside, in the direction of the track have a different dimension than the base plate moulding 18. During a displacement of the cover plates against the base plates, for example, an offset of the frontal impact, the stability of the level crossing increases, the flexible cover plate grid can serve to dimension the weights of the moulding, as desired.
(116) The base plate mouldings 18 are each fixed directly detachably but firmly to the rails 2, 2′, whereby generally it can be foreseen that the base plate mouldings 18 are detachably but firmly fixed in each case with the track system, in particular bolted. The cover plate mouldings 19 in contrast, are clamped under the rail heads 6. However, the cover plate mouldings 19 with the underlying base plate mouldings 18 are connected detachably but firmly, for example, fixed thereto, preferably by bolting.
(117) Referring to
(118) The base plate mouldings 18 laid between the rails 2, 2′ and the cover plate mouldings 19 extend transverse to the track section from the first rail 2 to the second rail 2′ and the base plate and cover plate mouldings 18, 19 adjoining one of the outer sides of one of the two rails extend from the respective rail to the subsequent, not shown here, traffic area.
(119) The lower base plate moulding 18 rest in each case on the rail foot 4 of the respective rails 2, 2′, and are based on it, whereby said recesses 29″, 39″ are foreseen for the rail-foot securing devices 10, 12 (see
(120) Arranged between the rails the base plate mouldings 18 preferably do not intervene in the rail chamber and does not fill-out the rail chamber, so that the base plate moulding 18, arranged between the rails, can be lowered during installation vertically from above up to the rail foot 4, without having to be located in the rail chamber. Rather, the rail chambers are filled-out on the inner side of the rails 2, 2 with filler block elements 22″ ″. By contrast, the base plate mouldings 18 bordering on the outer sides of the rails intervene in the rail chambers and fill them out, because these mouldings can laterally be inserted into the rail chamber before the connection is made to the adjacent traffic area. Thus, one can dispense with filler block elements on the outer sides of the rails. This can be provided similar to the vertical one-piece design of the intermediate rail mouldings 20 and/or track outer-side mouldings 30, 32.
(121) Using bolts 102, the top plate mouldings 19 can be bolted to the base plate mouldings 18, wherein the bolts 102 are shown here only for the outside mouldings. Four bolts each can, for example, be provided for the cover plates between the rails and two bolts for the outside cover plates.
(122) Referring to
(123) In order to further improve the horizontal fixing of the cover plate mouldings 19 with respect to the base plate mouldings, a positive engagement of a moulding projection 110 into a moulding recess 112 is considered expedient. In the illustrated example, the cover plate mouldings 19 have positive projections 110, which as negative recesses 112 are to be found in the base plates mouldings 18. The moulding projections 110 and the moulding recesses 112 are preferably set up so that a securing of the cover plates is carried out both longitudinally and transversely to the rail route. To the person skilled in the art it becomes apparent that the above-described embodiments are to be understood exemplary and the present disclosure is not limited to these, but can be varied in many ways without departing from the scope of the claims. Further, it is evident that the characteristics regardless of whether they have been disclosed in the description, claims, figures or otherwise, define individual components of the present disclosure, even if they are described together with other features.
