    专利说明:

    The invention relates to a prestressable ground anchor according to the preamble of claim 1.
    There are known anchoring anchors, which are intended to transfer an applied tensile force to a layer in the ground. In this case, the Verpressanker on a arranged in the underground pressing body, which are connected via pull members with an anchor head. The anchor head is in this case connected to the structure to be held or lies against this, which is thereby anchored by means of the prestressed tension members to the ground. Such anchoring anchors can be used here as a temporary anchor or as a permanent anchor. Steel is usually used for the tension members in conventional ground anchors. However, this has the disadvantage that from a steel tension member in a temporary anchor, which is used for example to secure a pit, must not remain in the ground. This is particularly important in the urban area, where the tension members often protrude into neighboring properties. A steel tension member is a major obstacle in excavating another pit or driving a channel or tunnel, as it is difficult to cut through for conventional construction equipment.
    A possible solution to this problem is the use of glass fiber cables as tension members, as they are easier to cut than steel or other metal members, so they can be left undisturbed in the underbody.
    A disadvantage of known anchoring anchors with fiber optic cables as tension members, however, is that they are much more complicated to handle and require expensive preloading constructions.
    The object of the invention is therefore to provide a prestressable anchoring anchor of the type mentioned, with which the mentioned disadvantages can be avoided, which is easy to handle and can be biased by conventional means.
    This is achieved by the features of claim 1 according to the invention.
    This results in the advantage that a prestressable squeeze anchor with members made of a non-metallic fiber material can be tensioned by conventional means. The coupling device with which the links are glued can provide a simple and easy to make transition to a conventional tension link, whereby the tension link can be pre-tensioned by the tension link using conventional methods and apparatus. This provides the user with the ability to use the same bracing devices when using the subject squeeze anchor as with conventional squeeze anchors with steel draw links. As a result, for example, the device insert can be held in a building structure, and recourse can be had to approved and proven biasing methods and devices. By using a non-metallic fiber material as Ankerzugglieder these can easily remain in the ground even after dismantling of the excavation, as they are easily durchtrennbar. Furthermore, this can be achieved a compact design, whereby the diameter of the wellbore can be kept low. The adhesive connection in this case a particularly simple trained but also durable coupling of the Ankerzugglieder with the coupling device can be effected, whereby damage to the Ankerzugglieder can be avoided, which for example in a pure mechanical connection such as terminal would be given.
    The subclaims relate to further advantageous embodiments of the invention.
    It is hereby expressly referred to the wording of the claims, whereby the claims at this point are incorporated by reference into the description and are considered to be reproduced verbatim.
    The invention will be further described with reference to the accompanying drawings, in which only one preferred embodiment is shown by way of example. Showing:

    Fig. 3 shows the preferred embodiment of the prestressable anchoring anchor as a section in side view.
    Figures 1 to 3 show a preferred embodiment of a prestressable injection anchor 1 comprising a plurality of anchor ties 2. An anchor anchor 1 is also referred to as a prestressed anchor or as a ground or rock anchor. The pressure anchor 1 is a geotechnical component which transmits an applied tensile force to the ground 10. In this case, a borehole 11 is introduced into the underground 10, the anchor pull members 2 are introduced into the borehole 11 and then anchored to the tiebacks 2 in the borehole 11 by means of a grout body 12. The compact 12 may be cement, concrete or the like.
    The Ankerzugglieder 2 comprise a non-metallic fiber material. Fiberglass cables offer the advantage that they have a high tensile strength, are chemically resistant and easy to manufacture. Alternatively, carbon fibers, synthetic fibers such as aramid or nylon, natural fibers, ceramic fibers or the like may be used for the anchor tangs 2. Furthermore, the anchor pull members 2 may in particular comprise a composite material comprising non-metallic fiber material.
    It is provided that the Ankerzugglieder 2 are glued at one end 6 by means of an adhesive 3 with a coupling device 4, and that a tension member 5 for tensioning the prestressable injection anchor 1 is at least indirectly connected to the coupling device 4. The coupling device 4 connects the Ankerzugglieder 2 with a tensioning tension member 5, wherein the tensioning tension member 5 is to be tensioned with a tensioning device 9. The tensioning tension member 5 can in this case in particular be made of metal, in particular of steel. Furthermore, it can be provided that the tensioning tension member 5 is designed as a steel tension member. Thereby, the tensile forces of the tensioner member 5, which can be tensioned by conventional means, can be easily and reliably relayed to the anchor tension members 2 and through the anchor tension members 2 via the compression body 12 to the ground 10.

    The injection anchor 1 can be designed, in particular, as a short-term anchor or as a temporary anchor. Such anchors 1 are provided for a service life of only a few years. By using the non-metallic fiber material, the anchor pull members 2 can remain in the base 10, whereby the degradation cost can be substantially reduced.
    Alternatively it can be provided that the ground anchor 1 is formed as a permanent anchor. Such anchoring anchors 1 are provided for a long service life, for example, at least one hundred years. Here, the tether members 2 comprising nonmetallic fibrous material may be more corrosion resistant than metal anchor tying members 2.
    In particular, the pressing body 12 may be arranged substantially only adjacent to the other end 13 of the Ankerzugglieder 2.
    Alternatively it can be provided that the injection body 12 substantially fills the entire wellbore 11.

In this case, the sheath 15 can envelop individual Ankerzugglieder 2 or a whole strand of Ankerzugglieder 2. Through the freewheeling section 14, the Ankerzugglieder 2 can pass on the tensile forces of the coupling device 4 unhindered to the grout body 12, wherein the Ankerzugglieder 2 can stretch under the bias in the freewheeling track 14 also unhindered. By the sheath 15, the Ankerzugglieder 2 in the freewheeling path 14 with the Verpresskörper 12 are not in contact.

    Particularly preferably, it can be provided that the Ankerzugglieder 2 extend parallel to each other.
    Furthermore, it can be provided that the Ankerzugglieder 2 are at least four times as long as the tensioning tension member 5. Here, the Ankerzugglieder 2 can be left in the background 10, while in a short-term anchor only the shorter tension member 5 is to be removed.
    Particularly preferably, it can be provided that the adhesive 3 is a resin, preferably a synthetic resin, in particular an epoxy resin. Resins have the advantage of easy implantability by means of casting. Furthermore, epoxy resin is water resistant.
    Furthermore, it can be provided that the one end 6 of the Ankerzugglieder 2 in the
    Adhesive 3 is embedded. In this case, a particularly large adhesive surface can be achieved. Furthermore, this can prevent the penetration of corrosion-causing fluids into the coupling device 4 and the underlying areas.
    Particularly preferably, it can be provided that the coupling device 4 has a sleeve 7, and that the one end 6 of the Ankerzugglieder 2 is disposed within the sleeve 7. The sleeve 7, which is shown partially cut away in FIGS. 1 and 3, surrounds the ends 6 of the anchor pull members 2 and is adhesively bonded thereto by means of the adhesive 3. Through the sleeve 7, a good integration of the ends 6 of the Ankerzugglieder 2 can be achieved, whereby 7 defined area can be provided by the sleeve, which can be poured from the adhesive 3. The sleeve 7 may be formed in particular comprising metal and / or plastic. Furthermore, the sleeve 7 may in particular have a hollow cylindrical shape.
    Furthermore, it can preferably be provided that the coupling device 4 has a length of less than 2 m. As a result, it can be easily removed from the substrate 10 during a short-term anchorage.
    The length of the sleeve 7 may correspond substantially to the length of the coupling device 4.
    In particular, it may be provided that the Ankerzugglieder 2 extend substantially over the entire length of the sleeve 7 in the sleeve 7. In other words, the Ankerzugglieder 2 can be arranged over the entire length of the sleeve 7 in the sleeve. As a result, a particularly large adhesive surface can be provided.
    In particular, it can be provided that the ground anchor 1 has only one tension member 5. The one tension member 5 may be formed here as a strand, rod or rope.
    Alternatively, it can be provided that the injection anchor 1 comprises a plurality of tension cables. In this case, provision may in particular be made for the number of anchor pull members 2 to be greater than the number of tension pull members 5.
    Particularly preferably, it can be provided that a first region 8 of the tensioning tension member 5 is arranged inside the sleeve 7. In this case, the first region 8 of the tension cable member 5 and the one ends 6 of the Ankerzugglieder 2 in the sleeve 7 may be arranged overlapping, whereby a particularly good power transmission through the adhesive 3 is possible.
    Furthermore, a second region 16 of the tensioning tension member 5 of the tensioning tensioning member can be provided, which can be braced with a tensioning device 9. The tensioning device 9 is hereby provided for applying and holding the clamping force.
    Particularly preferably, it can be provided that the tensioning tension member 5 has a thread for engagement of a tensioning device 9. The tensioning device 9 can here in particular have an internal thread, wherein by turning the tensioning device 9, the tensioning force can be adjusted and the pretensionable pressure anchor 1 can be easily tightened. In particular, it can be provided that the tensioning tension member 5 is designed as a threaded rod.
    Alternatively it can be provided that the clamping device 9 is provided as a perforated plate with wedges. Here, the tension member 5 can be tensioned by means of an external device and then fixed in the perforated plate with the wedges in the prestressed situation.
    Particularly preferably, it can be provided that the Ankerzugglieder 2 are arranged substantially uniformly distributed around the first region 8 of the Spannzuggliedes 5. This allows a particularly uniform force transmission of the many Ankerzugglieder 2 made to the tensioning member. Furthermore, the coupling device 4 can thereby be designed to be particularly simple and space-saving.
    Such an arrangement is shown in Figure 2, with the individual strands of the armature tines 2 arranged in a circular array about the central tension cord member 5. The tensioning cable member may in particular be coaxial with the sleeve 4.
    Furthermore, it can be provided that the prestressable anchoring anchor 1 at least three Ankerzugglieder 2, in particular five to twenty Ankerzugglieder 2, having.
    Here, the introduction of force can be forwarded particularly evenly over the individual Ankerzugglieder 2 to a centrally arranged tensioning tension member 5.
    In particular, it can be provided that a diameter of the tensioning tension member 5 is greater than a diameter of the anchor tension members 2. In this case, the Ankerzugglieder 2 can be better circumferentially arranged around the tensioning tension member 5, whereby a uniform force transmission is improved.
    Furthermore, it can preferably be provided that the tensioning tension member 5 is glued directly to the adhesive 3 with the coupling device 4. In this case, it is possible to dispense with the use of additional connecting means, as a result of which the coupling of the tensioning tension member 5 to the coupling device 4 can be made particularly simple. It can be provided that the tensioning tension member 5 is glued substantially on its lateral surface.
    In particular, it can be provided that the tensioning tension member 5 and the anchor tension members 2 are embedded in an adhesive formed as a resin. Such a connection is shown in Fig. 2, with the tension link 5 and the annularly arranged anchor pull members 2 embedded in the resin.
    Alternatively, it can be provided that the coupling device 4 has a connecting device, and that the tensioning tension member 5 is connected to the connecting device. In particular, the connecting device may be designed as a releasable connection of the tensioning tension member 5. For example, the connecting device may be formed as a threaded sleeve into which the tensioning tension member 5 is screwed. Furthermore, the connecting device may be fastened to the sleeve 7. The connecting device has the advantage that the tensioning tension member 5 can be easily detached from the coupling device 4, whereby the dismantling of the pressure anchor 1 can be made particularly simple.
    Furthermore, it can be provided that an injection tube passes through the sleeve 7. The injection tube serves to guide the material for the injection body 12 to the bottom of the bore hole 11. To save space that injection tube between the tensioning member 5 and the anchor members 2 are guided through the sleeve 7, and dorteingebettet. As a result, a particularly compact design can be achieved.
