Abstract

A reinforcing element for concrete construction in the form of a set bolt which is formed of a rod-shaped section with a cross-sectional enlargement on the end is provided. Significantly, at least this cross-sectional enlargement is formed of glass-fibre reinforced plastic and has an axial bore in its centre, and that the bore and the area of the rod-shaped section surrounded by it engage with one another in a form-locking manner.

Claims

1. A reinforcing element for concrete construction comprising a set bolt including a rod-shaped section (1) with a cross-sectional enlargement (2) on an end thereof, at least the cross-sectional enlargement (2) on the end is formed of glass-fibre reinforced plastic and has an axial bore (3) in a center thereof and the bore (3) and an area of the rod-shaped section (1) surrounded by the bore engage with one another in a form-locking manner.

2. The reinforcing element according to claim 1, wherein

the form-locking engagement is formed by a profiling (4, 5) effective primarily against axial forces.

3. The reinforcing element according to claim 1, wherein

the form-locking engagement is formed by threads (4, 5).

4. The reinforcing element according to claim 1, wherein

the cross-sectional enlargement (2) has a tubular extension (2a) extending along the axial bore (3).

5. The reinforcing element according to claim 4, wherein

the tubular extension (2a) has an axial length which corresponds to at least three times a diameter of the bore (3).

6. The reinforcing element according to claim 4, wherein

the tubular extension (2a) is profiled on an outer side thereof.

7. The reinforcing element according to claim 4, wherein

the tubular extension (2a) has a wall thickness that increases in a direction toward the cross-sectional enlargement (2).

8. The reinforcing element according to claim 4, wherein

the tubular extension (2a) passes into the cross-sectional enlargement (2) at an angle of less than 90°

.

9. The reinforcing element according to claim 1, wherein

the cross-sectional enlargement (2) is sprayed or injection-moulded onto the rod-shaped section (1).

10. The reinforcing element according to claim 1, wherein

the rod-shaped section (1) consists of glass-fibre reinforced plastic.

11. The reinforcing element according to claim 1, further comprising

an insulating body (10) for insertion between a building ceiling (12) and a balcony platform (11).

12. The reinforcing element according to claim 1,

the outer end of the cross-sectional enlargement (2) is formed by a plane (14a) which is oblique to an axial direction.

17. The reinforcing element according to claim 5, wherein

the tubular extension (2a) has an axial length which corresponds to at least four times the diameter of the bore (3).

18. The reinforcing element according to claim 4, wherein

the tubular extension (2a) passes into the cross-sectional enlargement (2) at an angle of less than 60°

.

13. A method for producing a reinforcing element for concrete construction in the form of a set bolt which is formed with a rod-shaped section (1) with a cross-sectional enlargement (2) on an end thereof, comprising

producing the rod-shaped section (1) with a profiling (4), and

attaching the cross-sectional enlargement (2) on the end by engaging an outer profile (4) of the rod-shaped section (1) in a form-locking manner with an inside profile (5) of the cross-sectional enlargement.

14. The method according to claim 13, wherein

the cross-sectional enlargement (2) is applied by spraying or injection moulding.

15. The method according to claim 13, wherein

the cross-sectional enlargement (2) is firmly connected with the rod-shaped section (1).

16. The method of claim 14, wherein a tubular extension (2a) is simultaneously applied by spraying or injection moulding.
