Abstract

A molding arrangement for creating a recess when casting a building part for connecting the tensile reinforcement element to the building part, with the molding arrangement including at least one molding element (2) to form the recess (5) as well as at least one anchoring element (3) for the creation of a form-fitting connection between the building part and a filler material to be introduced into the recess. Additionally the invention provides a building element for thermal insulation between two building parts having the molding arrangement. And finally a method is disclosed to connect a reinforcement element to a building part.

Claims

1. A molding arrangement for creating a recess when casting a building part (6) made in-situ from concrete for connecting a tensile reinforcement element (7) to the building part, the molding arrangement (1, 11) comprises at least one molding element (2) to create the recess (5) for the reinforcement element (7) to be connected and at least one anchoring element (3, 13), and the anchoring element (3, 13) is arranged such that it is adapted to create a form-fitting connection between the building part (6) and a filler material that can be introduced into the recess (5) and cured and/or bonded.

2. The molding arrangement according to claim 1, wherein the anchoring element (3, 13) for production of the form-fitting connection between the building part (6) and the filler material to be introduced into the recess (5) which can be cured and/or bonded, at least partially projects into the recess formed by the molding element (2).

3. The molding arrangement according to claim 2, wherein the anchoring element (3, 13) for the production of the form-fitting connection between the building part (6) and the filler material to be introduced into the recess (5) which can be cured and/or bonded is adapted to at least partially projects from at least one of the recess (5) or the molding element (2) into an area of the building part (6) surrounding the recess.

4. The molding arrangement according to claim 1, wherein the anchoring element (3, 13) for the production of the form-fitting connection between the building part (6) and the filler material to be introduced into the recess (5) which can be cured and/or bonded at least partially crosses the molding element (2).

5. The molding arrangement according to claim 1, wherein the anchoring element (3) is embodied as a dead anchoring element and after the recess (5) has been created by the molding arrangement (1, 11) the anchoring element is adapted to remain in the building part (6) in order to create a form-fitting connection between the building part and the filler material that can be introduced into the recess (5).

6. The molding arrangement according to claim 1, wherein the molding element (2) is adapted to be removed after the creation of the recess (5) and prior to the connection of the reinforcement element (7) while leaving the anchoring element (3, 13) in at least one of the building part or the recess.

7. The molding arrangement according to claim 6, wherein the molding element (2) is adapted to be removed in at least one of a direction of a top of the building part (6) or a direction of an intended progression of the reinforcement element (7) to be connected.

8. The molding arrangement according to claim 1, wherein the anchoring element is formed as a partial section of the molding element itself or connected to the molding arrangement in one piece.

9. The molding arrangement according to claim 1, wherein the anchoring element (3, 13) comprises a reinforcement rod.

10. The molding arrangement according to claim 1, wherein the anchoring element (3, 13) is adapted to serve as a joint anchoring element for two or more adjacent molding elements (2) and the joint anchoring element is connected to a plurality of the molding elements arranged adjacent to each other such that a distance of the molding elements is adjusted to a grid of the tensile reinforcement elements (7) to be connected.

11. The molding arrangement according to claim 1, wherein the molding element (2) is bowl-shaped or box-shaped and is adapted to be arranged in the building part (6) in an essentially flush fashion with a top and a face for a respective positioning of the recess (5) adjacent to a top (6a) and a face (6b) of the building part (6).

12. The molding arrangement according to claim 1, wherein the molding element (2) comprises at least one of a thin-walled plastic or metal.

13. The molding arrangement according to claim 1, wherein the filler material that can be cured and/or bonded comprises a cement-containing, a cement-containing and fiber-reinforced material, a resin mixture, or a reacting resin material.

14. A building element for thermal insulation (21) between a supporting building part (6) and a supported projecting exterior part, comprising an insulating body (22) adapted to be arranged between the two building parts with reinforcement elements (7, 8) crossing between them, which can be connected to both building parts including at least tensile reinforcement elements (7), and a molding arrangement (1, 11) a molding element (2) and an anchoring element (3, 13) allocated to the tensile reinforcement elements (7) at a side of the building part (6).

15. The building element for thermal insulation according to claim 14, wherein a plurality of the tensile reinforcement elements (7) are allocated to the joint molding arrangement (1, 11).

16. The building element for thermal insulation according to claim 14, wherein the molding element (2) is adjusted to a position, extension, and shape of the tensile reinforcement element (7) allocated thereto and the molding element (2) can be arranged at a distance from a position provided for the tensile element (7) and extending in the building part (6) at least approximately in an area of a tensile zone.

17. A method for connecting a reinforcement element to a building part, comprising the following processing steps:
