Definitions
- the invention relates to an impact anchor with the features of the preamble of claim 1.
- Such an impact anchor is known from DE 31 02 708 A1.
- the known drop-in anchor has a cylindrical anchor base part with a longitudinally extending hole which tapers over part of its length towards one end of the anchor base part. In order to be able to spread the anchor base part, it has slots in the area in which the hole tapers.
- the base part of the anchor in which the taper of the hole and the slots are located, can also be referred to as the expansion area.
- a bolt-shaped or pin-shaped expansion body is accommodated in the hole of the anchor base part, which can be displaced into the taper of the hole in the anchor base part and thereby expands or spreads the anchor base part in the expansion area.
- the drop anchor can be integrated in one
- the object of the invention is to propose an impact anchor of the type explained above with an improved anchorage.
- the anchor base part of the impact anchor according to the invention has edges on its outside which run at an angle to its longitudinal direction. Edges in the sense of the invention can also be understood to mean, for example, ribs or the like. The edges run, for example, helically on the outside of the base part of the anchor.
- the edges of the anchor base press into a borehole wall and bring about a positive fit when anchoring the insertion anchor in the borehole in addition to a non-positive connection caused by the spreading of the anchor base part. Anchoring force is increased. Furthermore, the edges have an effect
- an embodiment of the invention provides that the anchor base part has a polygon with helical edges.
- This anchor base part can be produced easily and inexpensively by twisting a polygon with originally straight edges.
- edges of the anchor base part preferably run obliquely in the same direction as a thread which is designed to fasten an object to the anchor base part.
- the edges also run right-hand, the edges preferably being very steep, i.e. run at an acute angle to a longitudinal direction of the anchor base part.
- One embodiment of the invention provides a push-back safety device for the expansion body.
- the purpose of this is to prevent the expansion body from moving back out of the tapering of the hole in the base part of the anchor.
- the expansion body can, for example, have a fir tree profiling as a slide-back protection, which counteracts a displacement of the expansion body against the tapering of the hole in the base part of the anchor. This configuration can also be independent of other features
- Embodiments of the invention may be implemented.
- Figure 1 shows an impact anchor according to the invention in side view
- Figure 2 shows the impact anchor from Figure 1 in axial section
- FIG. 3 shows an end view of the insertion anchor according to arrow III in FIG. 1.
- the impact anchor 10 according to the invention shown in the drawing has a
- Anchor base part 12 which is made of a polygon.
- a hexagonal steel rod has been used to manufacture the anchor base part 12.
- the hexagonal rod is around its imaginary Axis has been rotated so that edges 14 of the polygon extend helically, ie at an angle to a longitudinal direction of the anchor base part 12.
- the edges 14 are right-handed, they have a very large slope, they run at an acute angle to a longitudinal direction of the anchor base part 12.
- the anchor base part 12 is provided with transverse, intersecting longitudinal slots 16, which extend over a little less than half a length of the anchor base part 12.
- the anchor base part 12 has an axial through hole 18, which is in the area of the
- Longitudinal slots 16 taper conically and which is cylindrical outside the longitudinal slots 16.
- the longitudinal slots 16 or the tapering part 20 of the through hole 18 define an expansion area 22 of the anchor base part 12.
- the cylindrical part of the through hole 18 is provided with an internal thread 24.
- an expansion body 26 is slidably received in the through hole 18.
- the expansion body 26 has a cylindrical section 28 and a conical section 30 which is complementary to the taper 20 of the through hole 18.
- a diameter of the cylindrical section 28 of the expansion body 26 corresponds to a diameter of the cylindrical part of the through hole 18 of the anchor base part 12.
- the expansion body has a fir tree profiling 32, which forms a push-back protection.
- a plastic washer 35 is inserted as an anti-loss device, which holds the expansion body 26 in the through hole 18 of the base body 12
- the impact anchor 10 For anchoring in a borehole (not shown), the impact anchor 10 is hammered into the borehole, for example with hammer blows, the expansion region 22 being located at the front in the direction of impact. The impact anchor 10 is sunk flush into the borehole. Subsequently, the expansion body 26 is in a wrench, not shown, or by screwing a screw into the internal thread 24
- the expansion body 26 expands or spreads the anchor base part 12 in the expansion area 22 and in this way anchors the impact anchor 10 in the borehole.
- the edges 14 of the anchor base part 12 press into a borehole wall. Also when spreading, the edges 14 in the expansion area 22 press into the borehole wall. In this way, there is a positive anchoring of the insertion anchor 10 in the borehole in addition to a non-positive anchoring by spreading the anchor base part 12. The anchoring is thereby improved.
- An object, not shown, can be fastened to the internal thread 24 of the insertion anchor 10 with a screw, not shown.
- the internal thread 24 is a right-hand thread, so it rises in the same direction of rotation as the edges 14 of the anchor base part 10, even if the slopes of the edges 14 and the internal thread 24 are completely different. As a result, the edges 14 counteract a torque when screwing in and tightening a screw into the internal thread 24.
