Description

(1) The invention will be explained in greater detail below with reference to the accompanying schematic drawings. The depicted embodiments merely represent examples of how the device according to the invention might be configured and do not constitute a firm restriction. In the drawings,

(2) FIG. 1 shows a perspective view of a composite element according to the invention with a sectional view of a fastening element according to a first exemplary embodiment;

(3) FIG. 2 shows a perspective view of the composite element according to FIG. 1.

(4) In the following description, the same reference numerals are used for the same and equivalent parts.

(5) FIG. 1 shows a perspective view of a composite element 10 according to the invention with a sectional view of a fastening element 11 according to a first exemplary embodiment. The composite element 10 has two components and a fastening element 11. The first component comprises an end wall 12 of a drainage channel. The end wall 12 is formed in particular from polymer concrete. The end wall 12 has a cylindrical assembly pin 13. In other words, the assembly pin 13 is configured as a cylindrical protrusion on the end wall 12. The assembly pin 13 protrudes perpendicularly from the end wall 12.

(6) The second component is configured as a steel bracket 15. The steel bracket 15 forms a kind of flat frame around the end wall 12. To connect the steel bracket 15 to the end wall 12, the steel bracket 15 has a recess that corresponds to the assembly pin 13 such that the bracket can be brought into full contact with the end wall 12. In other words, the steel bracket 15 abuts completely against the end wall 12.

(7) To fix the steel bracket 15 to the end wall 12, the fastening element 11 is mounted on the assembly pin 13. The fastening element 11 is configured as a clamping disk 11a or as a clamping element. In particular, the fastening element 11 is configured as an axial clamping ring. The axial clamping ring has a central recess 16. The geometric shape of the central recess 16 corresponds to the geometric shape of the cylindrical assembly pin 13. For example, the central recess 16 has a round shape. The central recess 16 serves to receive the assembly pin 13.

(8) The clamping disk 11a further has a plurality of clamping claws 17, for example. When mounted on the assembly pin 13, the clamping claws 17 are disposed at an angle to a plane of die clamping disk 11a. In other words, the clamping claws 17 protrude from the clamping disk 11a. When mounted, the clamping disk 11a or the clamping element is force-fittingly connected to the assembly pin 13. It is therefore not possible to detach the clamping disk 11a from the assembly pin 13 without destroying die clamping disk. The clamping disk 11a presses the steel bracket 15 against the end wall 12. The steel bracket 15 is therefore positioned between the clamping disk 11a and the end wall 12. The clamping disk 11a produces a secure and non-detachable connection between the steel bracket 15 and the end wall 12.

(9) FIG. 2 shows a perspective view of the composite element 10 according to FIG. 1. The structure of the composite element 10 is similar to that of FIG. 1. In contrast to FIG. 1, an elastic material for a seal is applied to an opposite side 12a of the end wall 12. The elastic material is in particular foam rubber 18/EPDM foam. The foam rubber 18 is positioned between the opposite side 12a of the end wall 12 and the steel bracket 15. The foam rubber 18 is therefore fixed on the opposite side 12a of the end wall 12. In other words, the foam rubber 18, or the seal, forms a coating on the opposite side 12a of the end wall 12. The steel bracket 15 and the foam rubber 18 together ensure that the opposite side 12a of the end wall 12 can be connected to an adjoining drainage channel in a fluid-tight manner. An additional process of gluing the foam rubber 18 to the opposite side 12a of the end wall 12 can generally be dispensed with.

(10) When the foam rubber 18 comes into contact with the polymer concrete on the opposite side 12a of the end wall 12, it can be partially dissolved on the surface of the opposite side 12a and bonded to the polymer concrete. This impedes a non-destructive separation of the foam rubber 18 from the opposite side 12a, and therefore, the foam rubber 18 is attached permanently to the opposite side 12a of the end wall 12.

(11) The steel bracket 15 can further have latching elements at its ends, in particular latching hooks, which engage in corresponding recesses in a side wall of the drainage channel. The foam rubber 18 can thus be pressed onto or into the opposite side 12a of the end wall 12 in a fluid-tight manner.

(12) It is also conceivable for the foam rubber 18 to be applied only in sections to areas that are to be scaled or in which foam rubber damping is required, e.g., to prevent rattling. Channel joints can also be sealed in this way. Advantageously, the foam rubber 18 can also be used to prevent undesirable relative slipping movements.
