Description

The invention relates to a rail assembly, suitable for pouring into concrete, with a rail with a rail body, wherein the rail body has a first side wall, a second side wall, a first rail lip protruding from the first side wall, and a second rail lip extending from the second Sidewall protruding, has. The invention further relates to a building with a concrete element in which such a rail arrangement is embedded.

It is, for example, from the WO13013876 A1 , Anchor rails known which are poured into a concrete element so that a rail slot of the respective anchor rail appears. Hammer head elements can be anchored in the anchor rail and thus on the concrete element via this rail slot.

The WO09083002 A1 shows an anchor rail, which is provided with additional transverse anchors. As a result, the carrying capacity of the anchor rail, in particular in the edge region of a concrete element at high shear forces to be improved. Another anchor channel with transverse anchors goes out of the EP2907932 A1 ( WO14058151 A1 ).

The object of the invention is in profile rails, which are embedded in concrete elements, to achieve particularly good load values, in particular for transverse loads, in a particularly simple and reliable manner.

The object is achieved by a rail arrangement with the features of claim 1 and a building with such a rail arrangement with the features of claim 9. Preferred embodiments are given in the dependent claims.

An inventive rail arrangement is characterized in that it comprises a stiffening element with a force receiving body, wherein the force receiving body of the first side wall of the rail for a contact of the first Side wall of the rail with the force receiving body, in particular for lateral force dissipation, is upstream.

A first basic idea of the invention can be seen in stiffening at least the first side wall of the profile rail by means of an additional, in particular separate, force-receiving body. This force receiving body is the first side wall of the rail upstream of the rail outside. When transverse load of the rail, the first side wall of the rail can be supported on the force receiving body, so that the lateral load can be transferred to the surrounding concrete over a large area, and thus a particularly advantageous flow of force is given. In particular, unwanted small-scale notch loads of the surrounding concrete can be counteracted particularly effectively, which allows a particularly good load bearing. According to the invention this is ensured by an additional element, namely by the stiffening element with the force receiving body. The proven concept of the rail can thus be maintained, so that the aforementioned advantages in terms of load behavior with particularly low production costs and compatible with known system and thus can be achieved with very little installation effort.

The force receiving body is spatially in front of the first side wall of the rail, on the outside of the rail, that is he covers the first side wall, in such a way that the first side wall is in contact with the force receiving body or at least can come into contact with the force receiving body, namely at a force-absorbing body directed towards lateral load on the rail. In the last-mentioned embodiment, initially there may be a gap between the first side wall and the force-absorbing body, which gap closes in the case of transverse loading of the profile rail towards the force-receiving body.

The first rail lip protrudes from the first side wall, in particular towards the second rail lip, and the second rail lip protrudes from the second side wall, in particular toward the first rail lip. In particular, a rail slot is formed between the two rail lips, through which a hammer head element, for example, a hammer head screw or a sliding block, can be inserted into the rail and then fixed by rotation on the rail lips. The first side wall and the second side wall are expediently parallel to one another. In particular, the first side wall and the second side wall are connected by a rail bottom, which may be flat in the simplest case, but which may also have more complex geometries such as a V-shape.

Preferably, at least the force receiving body, particularly preferably the entire stiffening element, consists of metal. Likewise, the profile rail is preferably made of metal.

It is particularly preferred that the force receiving body of the first side wall of the rail over a length of at least 50%, 75% or 90% of the length of the rail for a contact of the first side wall of the rail is preceded by the force receiving body. Accordingly, a contact between the first side wall and the force receiving body over a significant part of the length of the rail is possible, so that a particularly large-scale and thus advantageous transverse force dissipation is given. The force receiving body may also completely overlay the first side wall, that is, the force receiving body may be upstream of the first side wall over a length of at least 100% or more of the length of the rail for contact of the first side wall of the rail with the force receiving body. For this purpose, the force receiving body is expediently at least as long as the rail body. The length of the profile rail can be understood in a customary manner, in particular, its extent along its longitudinal axis and / or its extent along the rail slot and / or its extent perpendicular to the transverse direction.

Conveniently, the force receiving body on a contact surface for the first side wall of the rail body, which corresponds geometrically with the outer surface of the first side wall, which allows a particularly homogeneous transmission of force. If the outer surface of the first side wall is flat, this contact surface can in particular run parallel to the outer surface of the first side wall.

The force receiving body may preferably be a plate, which may allow a particularly good power transmission and / or a particularly low production cost. This plate preferably runs parallel to the first side wall of the rail body. In principle, however, the force-absorbing body could also be, for example, a rod, which may also be advantageous in terms of manufacturing technology.

Furthermore, it is expedient that the stiffening element has at least one stiffening rib, which protrudes from the, preferably designed as a plate, force receiving body, preferably protrudes at right angles. In particular, the stiffening rib projects from the mounting rail away from the force-absorbing body. By means of a stiffening rib, the force-absorbing capacity of the Force receiving body be further improved and / or a particularly good power transmission in the surrounding concrete are made possible. The force receiving body and the stiffening rib suitably form an L-shape. Preferably, the force receiving body and the stiffening rib are integrally formed, which can further reduce the manufacturing cost.

The stiffening rib preferably has the same length as the force receiving body, which may be advantageous in terms of the power consumption. Conveniently, the stiffening rib is arranged on the end side on the force receiving body, which can offer advantages in terms of production and manufacturing technology.

It is particularly preferred that the stiffening rib extends in a plane spanned by the rail lips. In particular, the stiffening rib lies in this plane. Accordingly, the stiffening rib is disposed at the level at which transverse forces are introduced into the rail body during operation, which allows a particularly good power consumption. In the plane spanned by the rail lips is also the rail slot.

In a further preferred embodiment of the invention, the rail arrangement has at least one force-diverting bar, which is connected to the stiffening element, in particular for introducing tensile forces from the stiffening element into the force-diverting bar. In particular, the connection between the stiffening element and the force dissipation rod in addition to the embedding of these two elements in the concrete, so even before pouring the rail assembly in the concrete. Particularly preferably, the connection between the stiffening element and the force dissipation rod on the force receiving body of the stiffening element. Such a force dissipation bar, which is preferably made of metal, is particularly advantageous in a near-edge arrangement of the rail assembly in the concrete element, since the force dissipation rod can relieve the edge of the concrete element and thus effectively counteract unwanted premature breakout of the concrete element near the edge. Expediently, the at least one force dissipation bar crosses the rail body, in particular when viewed in the direction of the rail slot and / or in the viewing direction perpendicular to the plane spanned by the rail lips. Preferably, the force dissipation bar is integrally connected to the stiffening element. For example, the force-diverting bar and the stiffening element can be connected to one another by a welded connection. The force dissipation bar can also be designed integrally with at least one part of the stiffening element, in particular integrally with the force-receiving body.

Preferably, the rail arrangement has a plurality of force dissipation bars, which are advantageously arranged as explained above. The force dissipation rods can in particular run parallel to one another.

The rail can be designed in particular as an anchor rail and accordingly, for a particularly good anchorage in concrete, have a plurality of anchors which protrude on the rail body, in particular of its rail bottom. For a particularly compact and particularly advantageous embodiment, it can be provided that the at least one force dissipation rod passes between two adjacent anchors.

Among other things, to enable a particularly simple and reliable positioning, it is particularly advantageous that the stiffening element is connected to the rail. In particular, the connection between stiffening element and rail in addition to the embedding of these two elements in the concrete, so even before the pouring of the rail assembly in the concrete, that is already at the suitable pouring into concrete rail arrangement. The connection between stiffening element and rail can be given, for example, on the anchors or on the rail bottom of the rail body.

The invention also relates to the intended use of the rail arrangement and thus in particular to a building structure with a concrete element in which an inventive rail arrangement is embedded, in particular cast. In particular, the rail arrangement is embedded in the concrete element such that the rail slot of the rail body emerges on a surface of the concrete element. In particular, the rail arrangement can be arranged in the vicinity of an edge of the concrete element, since such an arrangement can place particularly high demands on the transverse load behavior. Preferably, the rail body of the rail assembly is arranged parallel to the edge of the concrete element.

It is particularly preferred that the stiffening element, in particular its stiffening rib, comes to light on a surface of the concrete element, in particular on the same surface on which the rail body, in particular with its rail slot, comes to light. As a result, the introduction of force into the concrete can be further improved and / or the assembly and / or production can be further simplified.

Features which are explained in connection with the rail arrangement according to the invention can also be used in the building according to the invention, as well as conversely features which are explained in connection with the building according to the invention can also be used in the rail arrangement according to the invention.

The rail 2 has a rail body 20 with a first side wall 21, a second side wall 22, a first rail lip 23, a second rail lip 24 and a rail bottom 25. The first rail lip 23 is disposed at an upper end of the first side wall 21 and a second rail lip 24 at an upper end of the second side wall 22, the first rail lip 23 projecting from the first side wall 21 toward the second side wall 22 and the second rail lip 24 from the first side rail 21 second side wall 22 protrudes toward the first side wall 21. Between the two rail lips 23 and 24, a rail slot 26 is formed. Through this rail slot 26 through a hammer head element can be inserted into the interior of the rail body 20 and fixed there by rotation of the rail lips 23 and 24. The rail bottom 25 connects the two side walls 21 and 22 on the rail underside. In the illustrated embodiment, the two side walls 21 and 22 extend parallel to each other and the rail bottom 25 is V-shaped. In principle, however, other embodiments are conceivable, for example with a flat rail floor.

The rail 2 is designed as an anchor rail and as such has a plurality (here two) of anchors 29 which project from the rail body 20 downwards. In the present exemplary embodiment, the anchors 29 are arranged by way of example on the rail floor 25, but other, for example, lateral arrangements are also conceivable.

The stiffening element 4 is used for transverse stiffening of the first side wall 21 and the first rail lip 23 of the profile rail 2. The stiffening element 4 has a plate-shaped force receiving body 41, which is arranged for contact with the first side wall 21 directly in front of the first side wall 21. In the illustrated embodiment, the force receiving body 41 is substantially the same length as the first side wall 21 and thus as the rail 2. The stiffening element 4 further comprises a stiffening rib 47 which projects upright on the force receiving body 41 from the force receiving body 41, namely from the rail body 20 away , The plate-shaped stiffening rib 47 lies in particular in a plane spanned by the rail lips 23 and 24 level 97. In this plane 97 is also the rail slot 26. The stiffening rib 47 and the force receiving body 41 are here exemplified integral.

In the illustrated embodiment, the stiffening element 4 further comprises an eyelet 49, by means of which the stiffening element 4 is attached to the rail 2. This eyelet member 49 is disposed on the force receiving body 41 and has at least one passage through which an armature 29 is performed. By means of a nut screwed onto the armature 29, the loop element 49 is pressed against the rail body 20. As a result, the eye element 49 and thus the stiffening element 4 is fixed to the rail 2. In the illustrated embodiment, the eye member 49 is formed as an angled, integrally formed with the force receiving body 41 plate. In principle, however, other embodiments of the Ösenelements 49 are conceivable or, for example in FIG. 4 also shown embodiments without eyelet 49th

The embodiment of the FIG. 4 is a modification of the embodiment of the FIGS. 1 to 3 in which the loop member 49 is missing. In contrast to the design of the FIGS. 1 to 3 in which the stiffening element 4 is Z-shaped, the stiffening element 4 in the embodiment of FIG. 4 L-shaped.

In the embodiment of the Figures 5 and 6 the stiffening element 4 has an additional rib 81 which connects the force receiving body 41 and the stiffening rib 47 so that the additional rib 81, the force receiving body 41 and the stiffening rib 47 form a triangular hollow profile. The attachment of the stiffening element 4 to the rail 2 can be done in this case via end caps 82 which engage on the one hand in the interior of the rail body 20 and the other in the triangular hollow profile of the stiffening element 4.

In the embodiment of the FIG. 7 the stiffening element 4 is designed as a ring plate which surrounds the rail body 20.

In the embodiment of the FIG. 8 is the force receiving body 41 formed as a rod which is integral with two power dissipation rods 45 executed. The stiffening element 4 is connected by means of clamps 88 with the rail 2, which each act on a force dissipation rod 45 and an armature 29.
