Description

The invention relates to a system for mounting a provided for the attachment of a rail for a rail vehicle rod-shaped fastener in a recess which is formed in a substrate formed of a solid material.

Furthermore, the invention relates to a method for fastening a rod-shaped fastening element for fastening a rail for a rail vehicle in a recess which is formed in a substrate formed of a solid material.

Finally, the invention relates to a rail fastening point, which is made on a substrate formed of a solid material, wherein the rail fastening point comprises a fastening element which is inserted into a recess of the substrate and held there.

The ground on which a rail is fastened by means of an attachment point of the type in question here is usually formed of a threshold or plate, which is formed of concrete or a similar solid material.

It is self-evident that the rail to be fastened in such an attachment point has in the usual way in each case a rail foot, a rail web standing on the rail foot and a rail head supported by the rail web, which has a running surface on its upper side on which the rail wheels of the railroad roll off each rail vehicle as it passes the rail.

Rail attachment points of the type in question usually include at least one supported on the respective substrate guide plate, a spring element and a clamping element. The guide plate rests with a contact surface on the side of its associated longitudinal side of the rail foot and is at the same time supported against the ground so that it guides the rail sideways and absorbs the lateral forces triggered when passing over the attachment point and dissipates into the ground. The spring element is usually supported on the guide plate and simultaneously exerts a hold-down force on the rail foot, which presses the rail elastically against the ground.

The tensioning element, which is usually a screw or a bolt, serves to tension the spring element and to fix the guide plate to the ground. For this purpose, the clamping element is usually passed through a through hole in the guide plate and screwed into a recessed into the ground dowel. In this case, the clamping element is coupled to the spring element, that the spring element is increasingly stretched with increasing screw-in until a sufficient spring force acts on the rail.

As an alternative to the use of dowels, in which the respective clamping elements are screwed, it is also possible to use as clamping elements so-called anchor bolts, which are fastened with an anchor portion directly in the ground.

The dowels, anchor bolts and all other comparable functions adopting fasteners that are used in rail fastening points of the here in use and are fixed in the respective underground, each have a rod-shaped, linearly elongated shape.

Of course, rail fastening points of the type in question may comprise further plate elements or other components, for example, placed between the rail foot and the ground to give the rail fastening point a certain elasticity, the loads taken up by the rail or the components of the rail fastening point over a large area on the Distribute underground or electrical insulation of the rail against the ground effect.

If the base on which the rail fastening point is to be erected is a threshold or slab cast from concrete, the respective fastening means can be cast directly into the ground during their manufacture. This ensures an optimally accurate positioning.

However, if fasteners of the type in question are to be used in an existing substrate, for example for repair or new production, the recesses required for this purpose must be formed for example by drilling into the substrate. Subsequently, the fasteners are placed in their associated recesses. The free spaces then still in the region of the recesses are then filled with a filling material, by which the respective fastening element is fixed in the recess. The filler may also be a concrete or a specially tailored adhesive.

The object of the invention was to provide a system and a method for mounting a provided for the attachment of a rail for a rail vehicle rod-shaped fastener in a recess with which can be ensured even under the ruling in practice rough conditions that the respective fastener is held properly in the respective recess.

Likewise, a rail fastening point should be specified in which an optimal hold of the respective fastener in the associated recess of the ground is ensured by simple means.

With regard to the system, the invention proposes, in order to achieve this object, the system for mounting a rod-shaped fastening element provided for fastening a rail for a rail vehicle.

With regard to the method, the invention proposes to solve the above object, in the attachment of a rod-shaped, intended for the attachment of a rail for a rail vehicle fastener in a recess which is formed in a solid material formed from the substrate in To complete claim 8 specified steps.

Finally, the solution according to the invention of the above-mentioned object with respect to the rail fastening point is that such a rail fastening point is designed in the manner specified in claim 13.

Advantageous embodiments of the invention are specified in the dependent claims and are explained below as the general inventive concept in detail.

An inventive system for mounting a provided for the attachment of a rail for a rail vehicle rod-shaped fastener in a recess which is formed in a substrate formed of a solid material, thus comprises a fastened to the fastener spacers, on the outer circumference at least one projection is formed and having a receptacle in which the fastener is seated with spacers attached to it, wherein the maximum diameter of the envelope of the spacer in the region in which the projection is formed, equal to the maximum diameter at the location of the recess on which the Spacer sits when it is mounted together with the fastener in the recess.

With the help of such a spacer, the fastener can be easily positioned in the associated recess of the substrate, that around the entire circumference of the recessed in the recess portion of the fastener element between the inner peripheral surface of the recess and the outer peripheral surface of the fastener, a free space is provided with the filling of the fastener ensuring the maintenance of the fastener is filled in the recess. Characterized in that the spacer is provided with at least one projection which defines the distance of the fastening element to the inner peripheral wall of the recess in the region of the spacer provided with the projection, beyond an access opening is kept free after insertion of the fastening element and the spacer into the recess, over which the remaining space of the recess can be made with the filling material.

In the ready-to-use state, a combination of a fastening element and a spacer coupled to the fastening element is therefore available with the system according to the invention, enabling a simple, positionally secure mounting of the fastening element in an associated recess of the respective base. It is ensured that in the recess in sufficiently uniform distribution free space for filling with filler, which fixes the fastener in the recess. This free space is also still easily accessible when the fastener is positioned with the spacer in the recess.

• – Ausspritzen des im Bereich der Ausnehmung zwischen der Innenumfangsfläche der Ausnehmung und der Außenumfangsfläche des Befestigungselements vorhandenen Freiraums mit einem Füllmittel, das das Befestigungselement in der Ausnehmung fixiert.

An inventive method for fastening a rod-shaped fastening element for fastening a rail for a rail vehicle in a recess which is formed in a substrate formed of a solid material, comprises the following steps:

• Arranging a spacer in the recess, the spacer having a receptacle for the fastener and having at least one projection and the maximum diameter of the envelope of the spacer in the region in which the projection is formed, equal to the maximum diameter at the location of the recess is, on which the spacer sits when it is mounted together with the fastener in the recess;
• - Arranging the fastener in the recess of the substrate such that the fastener is seated in the receptacle of the spacer;
• - Injection of the in the region of the recess between the inner peripheral surface of the Recess and the outer peripheral surface of the fastener existing clearance with a filler that fixes the fastener in the recess.

A rail fastening point designed and manufactured according to the invention, which is produced on a substrate made of a solid material and comprises a fastening element which is inserted into a recess of the substrate and held there, is accordingly characterized in that the fastening element carries a spacer the outer circumference of which is formed at least one projection and having a receptacle in which the shank portion of the fastener sits, wherein the maximum diameter of the sheath of the spacer in the region in which the projection is formed, equal to the maximum diameter at the location of the recess on which the spacer sits when it is mounted together with the fastening element in the recess and in that the region of the recess between the inner peripheral surface of the recess and the outer peripheral surface of the fastening element existing clearance with a filling is filled medium, which fixes the fastener in the recess.

Optionally, the spacer is designed so that after the insertion into the recess, the fastening element is held centered in the recess by the spacer with respect to the opening cross-section of the recess. For this purpose, the peripheral shape of the spacer can be adapted in a suitable manner to the shape of the free cross section of the recess in the region in which the spacer sits after insertion into the recess. It is crucial that the projection is arranged so protruding beyond the circumference of the other portions of the spacer that always remains in the recess seated fastener and spacer the already mentioned through hole, which is required to fill the existing in the insertion direction below the spacer space ,

If the recess of the substrate is cylindrical in the manner of a bore with a circular cross section, an optimally positionally centered alignment of the fastener can be ensured by the spacer having at least three projections of equal length distributed at regular angular intervals around the central axis of its receptacle , The length of the projections is of course adapted to the opening diameter of the recess that all three projections are inserted in the recess inserted, the spacer bearing fastener, the projections evenly on the inner peripheral surface of the recess. In this way, the longitudinal axis and the longitudinal axis of the recess are then coaxially aligned with each other when assembled fastener.

As mentioned, the fastening elements to be fixed in a recess according to the invention can be anchor bolts, other rod-shaped fastening elements, such as threaded rods and the like. The invention proves to be particularly advantageous if the fastening element provided with a spacer according to the invention is a dowel which has a dowel opening formed on one end face for insertion of a fastening screw, a dowel tip formed on its other end face and a dowel opening which extends up to the dowel tip Shaft section has. Especially such dowels can be particularly if they are made of plastic, due to their low weight, their material properties and their comparatively low weight in a simple way to equip a spacer according to the invention and insert it into a recess so that they are optimally positioned by the spacer in position are held until they are fixed by means of the filling material in the recess.

The spacer can first be arranged properly regardless of the fastener in the respective recess, so that subsequently the fastener is introduced along with its insertion into the recess in the receptacle of the seated in the spacer spacer, which ensures the proper positioning of the fastener in the recess , In contrast, a simplified handling results when first a spacer is fastened to the fastening element and then the fastening element and the spacer are introduced jointly into the recess of the substrate.

In principle, it is conceivable to design the spacer provided according to the invention as a clip or the like, which is positively or non-positively coupled to the fastening element before it is introduced together with the spacer into the associated recess. However, a particularly simple handling results when the spacer has the basic shape of a ring whose annular opening forms the receptacle into which the fastening element can be inserted. Due to the circular shape of the opening of the spacer, a centric, coaxial alignment of the spacer and the fixing is automatically ensured if the fastener has a correspondingly uniformly shaped peripheral shape at least in the area to which the spacer is pushed. It goes without saying here by itself, that the opening cross section of the ring opening of the spacer is adapted to the peripheral cross section of the associated portion of the fastener so that the spacer is held in the pushed state without play on the fastener.

If the spacer made of plastic with a certain flexibility and is annular, so the opening cross-section of the spacer may have a certain undersize relative to the outer peripheral diameter of the associated portion of the fastener. This undersize can be designed so that, taking advantage of the elasticity of its material, the spacer is slightly stretched when inserting the fastener and so after insertion is positively and non-positively held on the fastener. In order to give the spacer a sufficient elasticity for this purpose, it may at least partially consist of an elastic material, with a particularly good usability then results if it consists entirely of an elastically deformable material, such as an elastic plastic. In order to facilitate the elastic deformation in the radial direction, the spacer may also be provided in the manner of a snap ring with a longitudinal slot.

According to a further advantageous embodiment of the invention, a plug element is provided in a system according to the invention, a method according to the invention or a rail mounting point according to the invention whose peripheral shape adapted to the shape of the portion of the recess in which the plug member sits when it is mounted in the recess in that, in the state mounted in the recess, the plug element bears tightly against the inner surface of the recess. In the prepared for filling with filler state of a rail fastening point according to the invention, the plug member then seals the lying in the insertion direction below the mounting portion portion of the recess relative to the surrounding space of the fastener. In this way, not only a smaller amount of filler is required for fixing the fastener, but also ensures a uniform filling of the surrounding space of the fastener, as an uncontrolled flow of filler is prevented in a deeper region of the recess. The use of a plug element of the type described above is thus always indicated when the length over which the recess extends into the substrate is greater than the length occupied by the portion of the fastener to be fixed in each case in the recess.

Like the spacer, the plug element can be arranged first and then the spacer and then or together with the spacer, the fastener in the recess. Again, the handling can be simplified, so that the plug element is first fixed in the region of the recess associated with the end of the fastener and then the plug member is inserted together with the fastener into the recess. It is crucial that the fastening element is arranged in front of the spacer in the recess, since otherwise the recess is no longer accessible for the plug element. In the event that the plug member to be attached to the fastener to then introduce it together with the fastener into the recess, it may be appropriate to provide the plug member with a receptacle into which the respective end portion of the fastener is inserted. For this purpose, the plug element may be formed, for example, annular. The opening cross section of the annular opening of the plug element is then optimally adapted to the peripheral cross section of that portion of the fastener to which the plug element is to be attached, that the plug element slightly elastically widened during insertion and so form-and there in the ready arranged on the fastener state is held positively.

The sealing effect of a plug element according to the invention can be optimized in that it consists at least in sections of an elastically yielding material. Optimally, in this case, the peripheral shape of the plug element has a certain excess with respect to the opening cross-section of the recess, so that the plug element, when it is positioned in the recess, acts with slight pressure against the inner peripheral surface of the recess. An elastic compliance of the plug element is also advantageous if the plug element in the manner described above is annular and under the action of an elastic restoring force after pushing to be held positively and non-positively on the associated portion of the fastener.

The filler, which according to the invention is filled in the space remaining after the positioning of spacer element and fastening element in the recess, can be any material which has sufficient flowability and at the same time, optionally after curing, is suitable for the fastening element to fix in the recess. Typically, fillers suitable for this purpose are a 2-component adhesive or injection mortar, wherein the fillers may each be based on epoxy or polyester resin. Depending on the nature of the substrate, the fastener and the recess, however, it is also conceivable to use as a filler flowable concrete or the like, which fixes the fastener in the recess of the substrate in the finished cured state.

The invention will be explained in more detail with reference to a drawing illustrating an exemplary embodiment. Each show schematically:

Im in 6 By way of example, rail fastening point B shown for a multiplicity of similarly constructed rail fastening points is fastened by a conventional rail S which comprises a rail head K and a web T bearing the rail head K which stands on a rail foot SF. The rail foot SF is in turn supported on a package P of plates, on the one hand cause a certain elastic compliance in the direction of gravity V and on the other hand, a uniform distribution of the forces acting in the direction of gravity V loads on the ground U on which the rail attachment point B is erected.

On both sides of the rail S, a guide plate W is arranged in each case, which bears in each case with a contact surface on the associated longitudinal side of the rail foot SF and is supported with its opposite side on a shoulder which is integrally formed on the substrate U. On the guide plates W each designed as a conventional tension clamp spring element F is supported, which exerts an elastic hold-down force on the rail foot SF with its free spring arms.

For clamping the respective spring element F and for simultaneous fixing of the associated guide plate W a clamping element E is provided in each case, which is a conventional sleeper screw here. The clamping element E is with its threaded shank through the middle loop of the spring element F and a passage opening arranged underneath the guide plate W in serving as a fastening element for the clamping means E and, consequently, for the rail S anchors 1 screwed into a recess 2 of the underground U is admitted.

The dowel 1 is with the help of in the 1 and 2 illustrated system 100 in the recess 2 of the underground U attached.

The recess 2 is formed in the manner of a bore cylindrical with a circular cross-section in the substrate U, which is, for example, a concrete poured threshold or plate. The inner diameter DA of the recess 2 is greater than the maximum outer diameter DD of the anchor 1 ,

The system 100 includes an annular spacer 3 , which is made of a total of elastic plastic material and at its outer periphery three at regular intervals of 120 ° around the central axis X of the spacer around distributed, protruding in the radial direction of it projections 4 . 5 . 6 wearing. The projections 4 . 5 . 6 are in each case by the same length LV of the circular ring section in plan view 7 of the spacer 3 from, which is also circular in cross-section ring opening 8th of the spacer 3 circumscribed. The diameter of the ring opening 8th is dimensioned so that it except for a small undersize the maximum outer diameter DD of the dowel 1 equivalent. At the same time, the outer diameter of the through the free end faces of the projections 4 . 5 . 6 fixed diameter of a cylindrical envelope H of the spacer equal to the inner diameter DA of the recess 2 ,

The dowel made of plastic 1 has a rod-shaped, elongated cylindrical basic shape. Its maximum outer diameter DD has the dowel made of plastic 1 in the region of its front edge area 9 on, the dowel opening 10 bounded, in which the clamping means E is introduced with its threaded shank. To the the dowel opening 10 bordering border area 9 closes a shaft section 11 of the dowel 1 on, to the dowel opening 10 opposite end of the dowel 1 in a dowel tip 12 ends. When inserted into the recess 2 of the subsurface U becomes the dowel 1 accordingly in the insertion direction Q with the dowel tip 12 ahead in the recess 2 pushed.

The system 100 further comprises an annular plug member 13 made of an elastically yielding material. The outer diameter DS of the plug element 13 is greater by a slight excess than the inner diameter DA of the recess 2 while the diameter DR of the ring opening 14 the plug element 13 except for a small undersize the outer diameter DP of the anchor 1 in the area of which the dowel tip 12 corresponding end portion corresponds.

For mounting the dowel 1 becomes the dowel 1 through the ring opening 8th of the spacer 3 pushed until the spacer 3 essentially free of play and flush with the free end face of the dowel 1 arranged on the edge area 9 sitting. In this case, the ring section 7 of the spacer 3 slightly elastically widened, leaving the spacer 3 additionally with slight adhesion to the dowel 1 is held.

Subsequently, the plug element 13 on the dowel tip 12 associated end portion of the dowel 1 postponed. This is also the plug element 13 slightly widened, so that it is also positive and non-positive on its associated portion of the dowel 1 sitting.

The combination of the fastening element (dowel) thus formed 1 , Spacers 3 and plug element 13 is then together in the recess 2 pushed in until the dowel opening 10 is arranged flush with the formed on the free upper surface O of the substrate U contact surface AF on which the respective guide plate W stands at the finished rail attachment point B. The projections 4 . 5 . 6 are doing with their free faces against the inner surface 15 the recess supported, so that in the recess 2 sitting dowel 1 the longitudinal axis LD of the dowel 1 coaxial with the longitudinal axis LA of the recess 2 is aligned. At the same time, the peripheral surface of the plug element lies 13 with slight pressure on the inner surface 15 on, so that in the insertion direction Q below the dowel 1 arranged section 16 the recess 2 opposite the free space above 17 is sealed, between the outer peripheral surface 18 of the dowel 1 and the inner surface 15 the recess 2 is available.
