"Tie rod anchoring"

The innovation concerns a prestressing steel anchorage for surface profiling having concrete reinforcement bars

The innovation is based on the task, one in the constructive Training to create the simplest possible prestressing steel anchorage, which is particularly suitable for such prestressing steels is whose surface on si «, b opposite sides with Ribs or parts of threads is provided.

According to the innovation, this task is solved by two das conical half-cualea encompassing the free end of the prestressing steel, whose inner wall is adapted to the surface profile, and stuck in a correspondingly conical inner hole provided with anchoring retaining ring, which is against the Front side of the concrete part is supported.

For better power transmission, there is an optional connection between the anchoring bracket and the face of the concrete part provided in this recessed head plate.

In a particularly space-saving embodiment, the anchoring retaining ring penetrates the head plate and lies against it with a covenant.

In the drawing, an embodiment serving as an example is shown.

Ss show:

Figure 1 shows a prestressing steel anchor in front view;

Figure 2 shows a section along the line AA in
Figure 1 and

Figure 3 shows a section according to Figure 2 through a
modified embodiment

Thereafter, a prestressing steel anchoring consists of two conical half-shells I ₁ 2, which encompass the free end of a prestressing steel 3. The latter is provided on its surface on opposite sides with surface profiles k in the form of mutually offset ribs. The inner surface of the half-shells 1,2 is adapted to this surface profile.

The half-shells 1, 2 are in an anchoring retaining ring 5 » which is designed as a socket with a conical inner bore 6 and has a collar 7. The latter is supported in the assembled Position against a head plate 8 which is embedded in the end face 9 of a concrete part 10.

According to Figure 2, the anchoring retaining ring 5 is arranged on the outside. However, a retaining ring 11 with a conical inner bore running in the opposite direction can also penetrate the head plate 12 (see Figure 3).

The drawing also shows a cladding tube 13 enclosing the prestressing steel 3.

The assembly of the new prestressing steel anchorage is extraordinary simple. In addition, the formation of the inner surface of the half-shells 1, 2, the insertion depth of the prestressing steel 3 and accordingly the preload can also be adapted to the respective conditions.

Claims (3)

Protection claims. 1. Prestressing steel anchoring for surface profiling Concrete reinforcing bars, characterized by two conical ones encompassing the free end of the prestressing steel (3) Half-shells (1, 2), the inner wall of which is the surface profile (4) is adapted, and stuck in an anchorage ring (5) provided with a correspondingly conical inner bore (6), which extends against the end face (9) the concrete part (lO) is supported. 2. Prestressing steel anchorage according to claim I _1, characterized in that an optionally embedded head plate (12) is provided between the anchoring retaining ring (5) and the end face (9) of the concrete part (10). 3. Prestressing steel anchorage according to claim 1 or 2, characterized in that the anchoring retaining ring (5 ^{) penetrates the} head plate (12) and rests against it with a collar (7).
