Rail mounting on concrete sleepers or similar. by means of elastic clamping clips

Description

The invention relates to rail mounting on concrete sleepers or pd. by means of elastic clamping rods of rod steel according to the introductory part of claim 1. Such, also, HM-rail mounting called rail mounting is described e.g. in DE-PS 12 61 151 (Meier) and DE-PS 19 54 008 (Munch). The HM-fastening session has been the best at home and around the world since its introduction. The very simple construction and the solid and durable silo locking of all parts only result in low complexity in the care of the tracks and thus low maintenance costs. Also, the duration of use of all fasteners proved to be good, because of the durable and elastic fastening on all fasteners, there is only a little wear and tear. Fasteners include rails between the rail and the concrete threshold, angular guide plates, clamping clamps, sill screws, as well as plastic sleeve inserts in the concrete sill for sill screws. A suitable angular guide plate for HM rail mounting is described e.g. in DE-PS 32 43 895 of the applicant.

Practically from the beginning of the introduction of HM-fastening at the German Federal Railways (orig .: Deutsche Bundesbahri) (cf. eg ETR 1968, p. 101) until today, HM-fastening has been carried out on concrete sleepers by means of clamping clamps or. The clamping brackets to allow pre-assembly on the concrete threshold were not invested in their normal position, but rotated 180 ° around the bolt stem, and were screwed to the construction site. This pre-assembly, in which the clamping clips against their mounting position were thus rotated 180 ° and fixed in the pre-assembly position, conditioned the release of the threshold screw and the manual rotation of the clamping clamp 180 °, with the free ends resting on the base of the rail, from the base of the rail away, the outer arches of the clamping clamp, however, came into the groove upwards of the open angular profile. In this position, the clamping clamp was secured to the concrete sill by a threshold screw.

While at t.im. The K-top structure, i.e. When laying rails on wooden sleepers, for some time a specially adapted clamping arches, which allow pre-assembly in the sill workshop in such a way that it is no longer necessary to rotate the clamping clamp from pre-assembly to mounting position, so far no satisfactory pre-assembly solution has been found at HM- upper structure. As an example of recent times for pre-assembly coupler couplings, please refer to the files of DE-PS 33 34 119 and 35 25 653 (SKL-12) of the applicant in the K-structure. Obviously, due to the special design of the corner guide plates, the HM-top structure has hitherto encountered problems in the manufacture of the coupling arch so that it can be transferred without rotation by 180 ° from pre-assembly to final assembly.

Thus, it is an object of the invention to improve the mounting of the rail of the aforementioned type so that the mounting of the HM rail mounting is feasible without the need to rotate the clamping arm by 180 ° so far in translation from pre-mounting to the mounting position. This saves at least two assembly-line workers and can be machined and reduced in cost, which is very much in line with the rationalization efforts of all line companies.

The object of the invention is solved by the rail mounting of the type mentioned above by means of the characteristic part of claim 1. Further features of the new rail mounting derive from the sub-claims. The special design of the new clamping joint, together with the adapted angular guide plate, enables easy pre-assembly as well as easy transition from pre-assembly to the mounting position after the rail is inserted on the track. All you have to do is move the clamping clip from its pre-assembly to its final mounting position and tighten the threshold screw. In doing so, from the rail base away from the arc, the clamping clips slide into the groove of the angular guide plate, while the free ends slip from the corresponding notches in the rib of the angular guide plate to the rail base.

Further details of the invention derive from the description of the drawing. In the drawing, FIG. 1 is a cross-sectional view of a rail profile with a new rail fastening according to the invention, in which the left side represents the mounting position in the outer rail space and the right side the pre-mounting position in the inner rail space in cross section, FIG. 2 is a rail view according to FIG. 1 in the plan, i.e. the left side of FIG. 2 shows the mounting position and the right side of the mounting position; 3 shows the clamping clip of the rail fastening according to the invention in the plan, FIG. 4 is a side view of the clamping clip of FIG. 3, viewed from the rail, FIG. 5 is a cross-sectional view taken along line V-V of FIG. 4, FIG. 6 is a spatial clamping clamp, FIG. 7 is an angular guide plate for a new rail mounting in the floor plan; FIG. 8 is a section along the line VIII-VIII of FIG. 7, FIG. 9 is a sectional view taken along the line ΙΧ-ΙΧ of FIG. 7, FIG. 10 is an angular guide plate for a new rail attachment in spatial layout, FIG. 11 the second, according to FIG. 3 shows a modified embodiment of the clamping clamp in the floor plan, FIG. 12 is a clamping clip according to FIG. 11 is a side view, viewed from the rail, FIG. 13 is a cross-section along the line ΧΙΙΙ-ΧΙΙΙ of FIG. 12, FIG. 14 is an angular guide plate according to FIG. 7 modified for the clamping clip of FIG. 11, in plan, FIG. 15 is a cross-sectional view taken along line XV-XV of FIG. 14, FIG. 16 is a cross-section along line XVI-XVI of FIG. 14, FIG. 17 is a further angular guide plate for a new track attachment in spatial projection, and FIG. 18 is a third angular guide plate for new rail mounting in spatial projection.

In FIG. 1 and 2, the rail fastening according to the invention is shown on the left half in each case in the mounting position and on the right half in each case in the pre-mounting position, in FIG. 1 in a central longitudinal section across the concrete threshold 4 and FIG. 2 in the plan, but the concrete threshold is dropped and the rail is cut outside the area of the clamping clamps 6, 6 '. The left side of the pictures shows the outside of the track and the right side shows the inside of the track; the rail 1 is thus represented in the outer space of the rail mounted and in the inner space of the rail pre-assembled. In addition, to distinguish different positions of the mounting elements, all parts, when in the pre-mounting position, are equipped with an apostrophe ('), while pure numbers are used in the mounting position.

As can be seen from FIG. 1, the support rail 1 shown here by the example of a known rail profile UIC 60, indirectly via the intermediate position 2 to the concrete sill 4 between the two angular guide plates 3, the rail axis being inclined in a known manner in the inner space of the rail in proportion, defined by the route in question, e.g. 1:40. The angular guide plates 3 each have one longitudinal rib 3a. The longitudinal ribs 3a rest on the two-sided base of the rail. The angular guide plates 3 are arranged in the recesses in the concrete threshold 4 extending along or along a part of the threshold.

In the mounting position, the free ends 6a of the clamping clamp 6 are pressed against the left foot of the rail, with the central part 6e of the clamping clamp 6 arranged for a small clearance a in a known manner above the rail foot 1a. In doing so, the head 5b of the sill screw 5 rests on the flattening 9 in the area of the inner arms 6d of the clamping clip, if not indirectly via the washer plate 7. The sill screw 5 is screwed onto the quadrilateral head 5c of the sill screw 5, in a known manner into the plastic sleeve 8 located in the concrete sill 4 until the desired clamping force is established and the deflection is obtained a. In the mounting position, the rear support arcs 6c of the clamping clamp 6 are resting in the guide groove 3e of the angular guide plate 3.

On the right side of FIG. 1 and 2 show the pre-assembly position in the cross-section and the plan. With the long design of the inner legs 6d of the clamping clip 6, it is possible to easily slide the clamping clip from the pre-mounting position 6 'to the mounting position 6, with the free ends 6a' sliding from their pre-mounting position in the recesses 3b in the rib 3a of the angular guide plate 3 over the oblique the surface 3g at the upper edge of the rib 3a adjacent to the rail foot, to the rail foot la and the rail foot, in such a way that they move so long that the rear support arcs 6c 'reach their position 6c at the bottom of the guide groove 3e of the angular guide plate 3 In the same way, the transition from the pre-assembly position to the assembly position is achieved with a modified clamping clip 10 according to FIG. 11 to 13 and the angular guide plate 12 of FIG. 14 to 16. In the case of a modified angular guide plate according to FIG. 18, by moving the clamping clamp from the pre-assembly to the mounting position of the plastic backrest 14i holding the clamping clamp in its pre-assembly position, are bent or respectively. ripped off. The projections projected on the rail side, shown in FIG. 18 and which serve as a backrest for the clamping clamp, can be provided with an attenuation for the purpose of facilitating folding or. tearing in the right place.

In this position, the threshold screw 5 'is then tightened in the manner described above with the help of a torque wrench and the mounting position 5, which is shown in FIG. 1 and 2 left.

While the HM assembly of the SKL-1 clamping clamp had to be rotated 180 ° at the transition from the pre-mounting position, the special design of the new clamping clamp 6 enables the simplified moving assembly described. The shape of the clamping clamp 6 is particularly clear from Figures 3 to 6. Thus, e.g. from the floor plan of FIG. 3, we see that the free ends 6a of the clamping clamp 6 lie in comparison with the known clamping clamps SKL-1 outside the projection of the greatly elongated central U-section 6e and 6d. However, to ensure that the new clamping clamp nevertheless retains the desired soft spring characteristic of the free ends 6a of known Omega clamping clamps, such as e.g. known SKL-1-clamping clips according to DE-PS 12 61 151, are outer arms 6b, as shown in FIG. 3, in relation to the inner arms 6d, when extended towards the base of the rail, is slightly obliquely positioned so that a sufficient length of spring-glass material of the clamping clamp is available at the free ends 6a.

The clamping clamp shown in FIG. 3 to 6, cooperates in the manner described above with a specially adapted angular guide plate 3 of FIG. 7 to 10. In addition to the known inner guide grooves 3c for the inner legs 6d for the inner arms 6d of the clamping clamp 6, as described in DE-PS 32 43 895, the angular guide plate 3 has a special outer cutout 3b for the free ends 6a of the clamping clamp 6 'in the pre-mounting position . In this position, the free ends 6a 'are stationary, as seen to the right of FIG. 2, in these special recesses 3b, the shape of which is adapted to the shape of the free ends 6a ', while the rear support arch 6c' rests on the surface of the concrete threshold 4 beyond the angular guide plate 3. The transition from the pre-assembly position to the assembly position is made by a simple movement of the clamp the clips perpendicular to the rail axis 1 in the direction of the rail, with the rear support arches 6c 'sliding into position 6c at the bottom of the guide groove 3c of the angular guide plate, while the free ends 6a' reach position 6a on the rail base la and there pressing up described way. As mentioned above, the backrests 14i provided in the embodiment of FIG. 18 on a corner guide plate 14, folded or torn off.

In FIG. 11, 12, 13 presents a slightly modified variant of the clamping clamp 10, which is also suitable for carrying out the movable assembly of the invention in a simple manner without rotating the clamping clamp on the concrete threshold. As can be seen further by comparing the clamping clamp 10 of FIG. 11 with clamping clip 6 of FIG. 3, ie when comparing the floor plans of the clamping clamps, the central area of the clamping clamp consisting of the middle part of the lOe and the two inner arms lOd is designed as the letter U, so that the area is not designed as the letter U but instead. the two U-arms 10d ₁ in the transition region to the rear support arcs lOc, ie in sections 10d ₂ , approach each other to a distance B. This distance B is less than the distance A in the area of the parallel inner arms 10d _p in which area lies the stem 5a of the threshold 5. In this way, it is ensured that the clamping clamp 10 'in the pre-mounting position holds the non-removable concrete sill even with the unscrewed threshold screw 5. This design further ensures that the clamping clamp 10 moves from its pre-mounting position 10' to the mounting position 10 does not leave the narrowing region for the sill screw 5, and with its two rear arches, lOc fits securely into the guide groove (3e, 12 e, 13e or 14e) angular guide plates used. The joints 11 follow the course of the parts 10dj and 10d _{2 of the} inner arms, thereby serving to secure the head 5b of the sill screw over the washer 7.

The clamping clamp 10 is precisely positioned in the pre-mounting position, that is, it rests securely in the receiving recesses 12b or. in the receiving groove 13b or in the recesses of the angular guide plates 12.13 or. 14, bounded by backrests 14i.

As further seen in FIG. 11, the recess in the course of the profile of the clamping clamp in the range 10d ₂ to a minimum distance B results in the convergence of the rear support arcs lOc, so that these support points of these arches are closer to each other in the guide groove 3e of the angular guide plate 3. It follows first for the clamp, a slightly different design in the area of the outer arms, namely the internal division into the free ends lOa, followed by adjacent sections 10b _x outer branches, and the latter following to the posterior supporting arcs lOc adjacent to the section 10b ₂ , as can be seen from the floor plan FIG. 11.

On the other hand, this design also allows the angular guide plate to be changed, as shown in FIG. 14 to 16. The ratio of the points of support in the rear support arcs lOc means that, compared to the angular guide plate 3, the altered angular guide plate 12 in the region of its guide groove 12e can be significantly shortened, thus saving the desired material material, without affecting function and strength, ie the reliability of the angular guide plate 12 compared to the larger angular guide plate 3. In addition, the material can also be spared in the area opposite the groove, as shown in the section in FIG. 16. Overall, for the embodiment of the angular guide plate 12 compared to the angular guide plate 3, the material savings are about 30% for the same basic dimensions.

If FIG. 12 is compared with FIG. 4, we find that apart from the described difference in the design of the arms lOb and lOd of the clamping clamp 10, the middle part lOe is also differentiated towards the middle part 6e, in such a way that it is extremely anterior, i.e. at the narrowest point on rail 1, the adjacent area of the middle portion lOe lies slightly more than the rest of the middle arc area. This is also evident from the center section of FIG. 13. This variant as such has nothing to do with the short-angle guide plate just described; it is applicable in the same way to the embodiment of FIG. 3 to 6 and is preferred if, as is customary in the case of certain foreign railway authorities, rail profiles are used whose rail base climbs more steeply, e.g. at a ratio of 1: 4, which corresponds to a rise of 14% compared to a rise of only 4% on the UIC-60 profile used as an example. The decision of the middle arc lOe, which is presented in FIG. 12 and 13, ensures that the condition of the middle part of the clamping clamp in the mounting condition is still maintained at a small distance a above the rail base a, even with the higher elevation of the rail base 1a.
