Description

The invention relates to a rail arrangement with an anchorless rail and with a filler, in particular for concreting into a concrete component or the like, according to the preamble of claim 1.

In construction technology, such rail arrangements are generally used in order to be able to fasten objects such as trapezoidal sheets or the like to them without having to drill holes in the concrete. For this purpose, the rail arrangement is typically concreted into the concrete component such that the outside of the floor facing away from the receiving space is exposed and is not covered by concrete. The filler body is arranged in the receiving space of the rail, which prevents the rail from being completely filled with concrete when the rail arrangement is concreted into the concrete component. In particular, a large part of the inside of the bottom of the rail facing the receiving space is kept free of concrete. This means that a screw can be screwed from the outside of the floor through the floor into the filler without having to drill a hole in the concrete. For this purpose, the filler body usually consists of a material into which the screw can be easily inserted.

From the EP 3 208 396 A1 a rail arrangement is known, the rail of which has a side wall with a hook section. A free space is formed between the hook section and the filler.

The invention has for its object to develop a generic rail arrangement such that it can be poured into concrete so that it is held securely in the concrete.

This object is achieved by a rail arrangement with the features of claim 1.

The invention provides that the free space projects into the imaginary cuboid. As a result, sufficient concrete can penetrate into the free space between the hook section and the filler during the concreting of the rail arrangement. As a result, the hook section on both sides of the side wall is surrounded by sufficient concrete and thus held securely in the concrete. When the rail arrangement is subjected to tensile loads, a force acts in the direction perpendicular to the flat outside of the floor away from the receiving space on the floor of the rail. This tensile force causes the surrounding concrete to exert a force on the hook section in the direction of the central plane. If the hook section is not adequately secured by concrete, this force can push it towards the center plane and thereby inadmissibly reduce the rail's holding forces in the concrete. This is prevented according to the invention in that the free space between the filler body and the hook section protrudes into the imaginary cuboid and thus a sufficiently thick concrete strip is formed between the hook section and the filler body.

One side surface of the imaginary cuboid extends in a contact plane. The investment level extends parallel to the central level. The at least one side wall lies against the plant level. The free space extends on both sides of the investment level.

In an advantageous development of the invention, a maximum width of the free space measured perpendicular to the central plane in the area of the hook section is at least along a partial section of the rail that extends in the longitudinal direction of the rail at least 1.5 times, in particular at least 2 times a distance between the hook section and the imaginary cuboid measured at the same height perpendicular to the central plane.

The hook section is advantageously inclined at an angle of 10 ° to 30 ° with respect to the central plane. As a result, the hook section forms an undercut in the concrete when the rail is poured into concrete. The rail is hooked into the concrete by means of the hook section.

The hook section expediently extends to the end face of the at least one side wall. This allows the concrete to flow easily to the hook section when pouring the rail.

The hook section expediently extends over at least 50% of the receiving space height. As a result, the rail can be held securely in the concrete when it is subjected to tension via the hook section. Due to the specified extent of the hook section, the free space extends in the direction of the receiving space height over a sufficiently large area of the rail. As a result, the free space is sufficiently large that the hook section is sufficiently surrounded by concrete when the rail arrangement is poured into concrete, in particular on the side of the hook section facing the packing, and is therefore adequately secured in the concrete.

The free space is expediently completely free of components of the rail arrangement. This allows enough concrete to flow into the free space and the hook section can be continuously secured by concrete in the area of the free space.

In an advantageous development of the invention, the free space is formed at least in an area which is essentially wedge-shaped in a cross section perpendicular to the longitudinal direction. A tip of the wedge-shaped region advantageously points towards the bottom of the rail. Due to the wedge shape of the wedge-shaped area and Due to the orientation of its tip, the wedge-shaped area is particularly wide in the area in which the greatest forces act on the hook section. As a result, the free space there is particularly wide, and a lot of concrete can act here to secure the hook section in the free space.

The wedge-shaped area expediently has an angle of at least 30 ° at its tip. The angle advantageously opens in the direction away from the floor.

In an advantageous development of the invention, the at least one side wall comprises a holding section. The holding section is advantageously inclined in the direction from the inside of the base towards the filler body towards the central plane.

The holding section is expediently arranged between the bottom and the hook section.

The filler body advantageously has a side surface facing the at least one side wall, which extends at least along the partial section of the rail extending in the longitudinal direction of the rail in the direction away from the floor towards the filler body toward the central plane. In this way, a space can be easily realized that protrudes into the imaginary cuboid.

In an advantageous further development of the invention, the filler body is held in a form-fitting manner in the receiving space of the rail by the holding section in the direction from the inside of the base to the filler body. As a result, the filler body can be held in the rail in a simple manner. The inclined profile of the side surface of the filler body advantageously corresponds to the inclined profile of the at least one side wall facing the side surface in the holding section of the at least one side wall such that the filler body is held in a form-fitting manner in the receiving space of the rail by the holding section.

The side surface of the packing is expediently inclined at an angle of 20 ° to 70 ° to the central plane. The angle advantageously opens to the floor.

In particular, the filler body is trapezoidal in a cross section perpendicular to the longitudinal direction. As a result, with a simple geometry of the filler body, a positive locking of the filler body by the holding section and a sufficiently large free space to the hook section can be achieved.

In an advantageous development of the invention, the filler is integrally connected to the inside of the base. As a result, no additional fasteners are required for fixing the packing. The filler is particularly glued into the rail.

In an advantageous development of the invention, the packing is arranged at a minimum distance from the at least one wall measured perpendicular to the central plane, the minimum distance being at least twice as large as the distance between the hook section and the imaginary cuboid. This means that the free space can be particularly large.

Fig. 1 shows a rail arrangement 1. The rail arrangement 1 comprises a rail 10 and a filling body 30. For a better overview, the filling body 30 is shown in FIG Fig. 1 shown with a dashed line. The rail 10 comprises two side walls 11, 12 and a base 13. The side walls 11, 12 and the base 13 extend in a longitudinal direction 100 of the rail 10. The side walls 11, 12 are connected to one another via the base 13. The side walls 11, 12 face each other. The side walls 11, 12 have inner sides 14, 15. The bottom 13 has an inside 16. The inner sides 14, 15 of the side walls 11, 12 and the inner side 16 of the base 13 jointly delimit a receiving space 17. The filling body 30 is arranged in the receiving space 17. The filler 30 lies against the inside 16 of the bottom 13. The bottom 13 has a flat outer side 20 facing away from the filling body 30. The flat outside 20 of the base 13 forms an uninterrupted, flat support surface which is unlimited by the rail 10.

The rail arrangement 1 is intended to be poured flush with the flat outside 20 in concrete. The side walls 11 and 12 protrude into the concrete. Objects such as trapezoidal sheets or the like can be attached to the flat outer side 20 without having to drill holes in the concrete. For this purpose, a screw can be seen from the flat outside 20 through the bottom 13 of the rail 10 in the Packing body 30 are screwed. The filler 30 is made of a material into which a screw can be easily inserted.

The rail 10 is an anchorless rail. The anchorless rail 10 is formed exclusively by the bottom 13 and the side walls 11, 12. No further components of the rail 10 for anchoring the rail 10 in the concrete are provided on the side walls 11, 12. As in Fig. 1 shown, the rail arrangement 1 has a central plane 50. The central plane 50 extends perpendicular to the outside 20 of the bottom 13 in the longitudinal direction 100. The rail arrangement 1 is symmetrical to the central plane 50. The side walls 11, 12 are opposite one another by the central plane 50.

The first side wall 11 has a hook section 18. The second side wall 12 has a hook section 19. A direction 80 extends from the inside 16 of the base 13 in the direction of the filler 30.

The hook section 18, 19 is inclined in the direction 80 away from the central plane 50 , In the opposite direction to direction 80, the hook section 18, 19 forms an undercut when the rail arrangement 1 is concreted in. The opposite direction corresponds to the direction in which a tensile force of a screw screwed into the base 13 acts on the rail arrangement 1. Through the hook section 18, 19, the rail 10 of the rail arrangement 1 hooks into the concrete. The first side wall 11 has an end face 21 facing away from the base 13. The second side wall 12 has an end face 22 facing away from the base 13. The rail 10 has a receiving space height H measured in the direction 80 perpendicular to the outside 20 of the base 13 from the inside 16 of the base 13 to the end face 21, 22 of the side wall 11, 12. In the exemplary embodiments, the first side wall 11 and the second side wall 12 are mirror-symmetrical to one another. If, however, one of the two side walls has a greater extent in the direction 80 than the other, the receiving space height is measured on the side wall which has a smaller extent in the direction 80. The filler 30 has a measured in the direction 80 perpendicular to the outside 20 of the bottom 13 Filler height F. The packing height F corresponds to 60% to 110%, in particular 90% to 110% of the receiving space height H. In the exemplary embodiments, the packing height F corresponds to the receiving space height H within the scope of the prevailing manufacturing tolerances.

A free space R1 is formed between the filling body 30 and the hook section 18. A free space R2 is formed between the filler 30 and the hook section 19. The free space R1, R2 extends over at least 50% of a height of the hook section 18, 19 measured parallel to the central plane 50. In the exemplary embodiments, the free space R1, R2 extends in the direction 80 over the entire height of the hook section 18, 19.
