Finally, the solution according to the invention of the above object with respect to the

Rail attachment point in that such

Rail fastening point is formed 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 for the attachment of a rail for a rail vehicle

provided rod-shaped fastener in a recess which is formed in a substrate formed of a solid material, thus comprises a fastener to the fastener spacer, on the outer circumference at least one projection is formed and having a receptacle in which the Fastener sits with attached to him spacer, wherein the maximum diameter of the envelope of the spacer in the area in which the projection

is formed equal to the maximum diameter at the location of the recess to which the spacer is seated when, together with the fastener in the

Recess is mounted.

With the help of such a spacer can be the

Fixing element so easily in the assigned

Position the recess of the base around the entire circumference of the portion of the fastener that is in the recess

Inner peripheral surface of the recess and the

Outer circumferential surface of the fastener, a free space is provided, which is filled with the maintenance of the fastener in the recess ensuring filling. Because of the spacer with at least one

Projection is provided in the provided with the projection portion of the spacer, the distance of the

Fixing element fixes the inner peripheral wall of the recess is beyond after the insertion of the

Fastener and the spacer in the

Recess an entrance opening kept free, over which the remaining space of the recess can be made with the filler.

In the ready to use state with the

System according to the invention thus a combination of a fastener and coupled to the fastener spacers available that a

simple, secure installation of the fastener in an associated recess of the respective underground allows. It is ensured that in the

Recess in sufficiently even distribution free space for filling with filler, which is the

Fixing element fixed in the recess. This

Free space is also still easily accessible when the fastener is positioned with the spacer in the recess.

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:

Placing a spacer in the recess, wherein the spacer is a receptacle for the

Fastener has and has 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 to which the spacer sits when it is in common with the fastener in the recess is mounted;

- 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 circumferential surface of the fastener existing Free space with a filler that the

Fixing element fixed in the recess.

An according to the invention and provided

manufactured rail fastening point, which is made on a substrate formed of a solid material and comprises a fastening element which in a

Recess of the subsurface is used and held there is, therefore, characterized in that the

Fastening member carries a spacer, on the outer circumference of which at least one projection is formed and having a receptacle in which the shaft portion of the fastener sits, 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 is where the spacer sits when he shares with the

Fastening element is mounted in the recess and that the area of between the inner peripheral surface of the

Recess and the outer peripheral surface of the

Fastening element existing free space with a

Filler is filled, which fixes the fastener in the recess.

Optionally, the spacer is designed so that after insertion into the recess the

Fastener is held by the spacer with respect to the opening cross-section of the recess centered in the recess. For this purpose, the peripheral shape of the spacer may be suitably adapted to the shape of the free cross section of the recess in the region in which the spacer after insertion into the Recess sits. It is crucial that the

Projection is arranged over the circumference of the other portions of the spacer protruding, that in seated in the recess fastener and

Spacer always the already mentioned passage opening remains free to fill the existing in the insertion direction below the spacer space

is required.

The recess of the substrate is cylindrical in the manner of a hole with a circular cross-section

formed so optimally locationally aligned alignment of the fastener can be ensured that the spacer at least three in

having regularly spaced angularly spaced around the central axis of its recording arranged projections of the same length. The length of the projections is included

of course so to the opening diameter of the

Recess adapted that all three projections inserted into the recess, the spacer bearing

Fixing element, the projections are supported evenly on the inner peripheral surface of the recess. In this way are then ready mounted

Fastening the longitudinal axis and the longitudinal axis of the recess aligned coaxially with each other.

As mentioned, it may be in accordance with the invention in a recess to be fixed fasteners

Anchor bolts, other rod-shaped fasteners, such as threaded rods and the like act. Particularly advantageous, the invention proves, if the

provided with a spacer according to the invention Fastening element is a dowel, which is formed on its one end face dowel opening for insertion of a fastening screw, a trained on its other end face dowel tip and the dowel opening

has bordering and up to the dowel tip extending shank portion. Especially such dowels can be especially if they are made of plastic, due to their low weight, their

Material properties and their comparable low

Load weight easily with a spacer according to the invention and in a recess so

insert that they are optimally held in position by the spacer until they are fixed by means of the filling material in the recess.

The spacer can be independent from the first

Fastener in the respective recess

be arranged properly, so that subsequently the fastening element is introduced along with its insertion into the recess in the receptacle of the seated in the recess spacer which the

ensures 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 that the invention

provided spacer as a clip or the like form the positive or non-positive with the

Fastener is coupled before sharing with the spacer is inserted 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. By the

circular shape of the opening of the spacer is

automatically a centric, coaxial alignment of the

Spacer and the fixing ensured when the fastener has a correspondingly uniformly shaped peripheral shape at least in the region to which the spacer is pushed. It also goes without saying that the opening cross section of the ring opening of the spacer to the

Circumferential cross section of the associated section of the

Fastener is adapted so that the

Spacer is held without play on the fastener in the pushed state.

If the spacer made of plastic with a certain flexibility and is annular, so can the

Opening cross section of the spacer a particular

Undersize compared to the outer diameter of the

have associated portion of the fastener. This undersize can be designed so that

Utilization of the elasticity of its material the

Spacer when inserting the fastener slightly stretched and so after insertion is held positively and non-positively on the fastener. To the spacer a sufficient for this purpose

To confer elasticity, it may at least partially consist of an elastic material, with a particularly good usability then results when he completely made of an elastically deformable material, such as an elastic plastic. To the elastic deformation in the radial direction

facilitate, 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 is provided in a system according to the invention, a method according to the invention or a rail fastening point according to the invention, a plug element whose peripheral shape to the shape of the portion of

Recess in which the plug member sits when it is mounted in the recess, is adapted so that the

Plug element in the mounted state in the recess rests tightly against the inner surface of the recess. In the prepared for filling with filler state of a

According to the invention prepared rail mounting point seals the plug then 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 for fixing the

Required fastener, but also a

ensures uniform filling of the free space surrounding the fastener, as an uncontrolled flow of filler into a lower region of the

Recess is prevented. The use of a

Plug element of the type described above is thus always displayed when the length over which the recess extends into the ground, is greater than the length which occupies the respective portion of the fastening element to be fixed 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 of the associated end of the fastener and then the plug member is inserted together with the fastener into the recess. It is crucial that the fastener is arranged in time before the spacer in the recess, otherwise for the

Plug element, the recess is no longer accessible. In the case that the plug element is to be fastened to the fastening element, in order to then share it with the

To introduce fastener into the recess, it may be appropriate to provide the plug member with a receptacle into which the respective end portion of the

Fastening element is insertable. This can be the

Plug element, for example, be 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 at least

partially made of an elastically yielding material. Optimal way, while the peripheral shape of the plug member has a certain excess over the Opening cross section of the recess, so that the

Stopper element, when it is positioned in the recess, with slight pressure against the inner peripheral surface of the

Recess acts. An elastic compliance of the

Plug element is also advantageous if the

Plug element in the manner described above annular and under the action of an elastic restoring force after pushing form and

frictionally connected to the associated portion of the

Fastener should be kept.

In the filler, which is filled according to the invention in the space remaining after the positioning of spacer element and fastener in the recess, it may be any kind of material, the one

has sufficient flowability and at the same time, optionally after curing, is suitable to fix the fastener in the recess.

Typically this is for this purpose

suitable fillers to a 2-component adhesive or injection mortar, wherein the fillers can each be based on epoxy or Polyestherha z. Depends on the

However, the nature of the substrate, the fastener and the recess, it is also conceivable as

To use filler flowable concrete or the like, which fixes the fastener in the recess of the substrate in the finished cured state.
