Definitions
- Such anchor heads and tie rods and their use are known. They generally serve to connect several layers of the substrate together and to induce forces that can lead to instabilities in the near-surface area of the subsurface in deeper underlying layers, which can absorb sufficiently large restraining forces.
- Tie rods are predominantly as rock anchors in the underground tunnels of mining, z. B. used in coal mines. Due to the spatially usually very cramped conditions rock anchors are often offset as a glue anchor in drilled boreholes. During the excavation work, they are mainly used for temporary protection of working face, parts of the ridges and in particular for securing the impacts in the area of the mineral / coal seam.
- tie rods can also be used as an end anchorage on reinforcing bars for concrete applications.
- Such a tie rod is known for example from DE 198 28 371 A1, to which reference is made for further details, in particular also for use and for the production.
- the anchor nut has a plurality of slots which are distributed uniformly circumferentially.
- two to six slots are provided, which face each other in pairs.
- a head region adjoins the air-side end of the cone-shaped bearing region of the anchor nut with an underside stop surface which is inclined to the longitudinal axis of the anchor nut at an angle which is greater than the angle in which the cone-shaped support region to the longitudinal axis the anchor nut is inclined.
- the abutment surface can come into contact with the anchor plate and make it difficult or prevent further retraction of the conical region of the anchor nut into the anchor plate.
- a head portion having a sudden increased diameter such that the underside-side end face of the head portion forms a perpendicular to the longitudinal axis of the anchor nut stop surface, which against a complementary abutment surface of the anchor plate can strike to prevent by this positive locking further retraction of the cone-shaped portion of the anchor nut in the inner cone of the anchor plate.
- the anchor nut In order to easily screw the anchor nut with a tool, it may be formed in a conventional manner with form-fitting elements, preferably with an external hexagon, wherein the positive-locking elements are advantageously arranged in the region of the head portion with the enlarged diameter.
- the anchor nut and / or the anchor plate consist of fiber-reinforced plastic, in particular of glass fiber reinforced plastic (GRP).
- GFP glass fiber reinforced plastic
- the anchor nut and / or the anchor plate can also be made of a metal alloy.
- the anchor plate is advantageously carried out circular, but it can also be square, in particular square.
- the anchor nut further comprises at least one preferably axially parallel slot which interrupts the nut wall over a portion of its axial extent, and which opens at the airside end of the anchor nut, from where it extends over a length of between 25% and 90%. the total axial length of the anchor nut is.
- the anchor nut 3 In the direction of the longitudinal axis 16, the anchor nut 3 is provided with a continuous threaded hole 17 whose internal thread 18 is adapted to the wave-like special thread profile 19 of the tie rod 2.
- the anchor nut 3 can first be easily screwed onto the tie rod 2 with little play, whereas later in radial compression or clamping of the cone-shaped support portion 7 in the inner cone 9, the internal thread 18 of the anchor nut 3 play and slip on the thread 19 of the tie rod second is determined.
- the head region 10 of the anchor nut 3 has a diameter that increases by leaps, whereby a stop face 24 extending perpendicularly to the longitudinal axis 16 of the anchor nut 3 is formed on the underside-side end face of the head region 10.
- This stop surface 24 can abut against a complementary abutment surface 25 which is formed on the air-side surface of the collar 20 of the anchor plate 4.
