    The invention relates to an anchoring system for concrete structures according to the preamble of claim 1 and an anchoring element and a cover for this anchoring element according to the preamble of claims 9 and 11.
    Concrete structures or partial concrete structures can comprise one or more concreted-in anchoring elements. Anchoring elements define accessible cavities in the respective concrete structure, which can be used to fasten or anchor additional elements.
    Such other elements are, for example, components such as tension rods, brackets, scaffolding, guardrails, lifting tools or formwork. The shape and the internal structure of such anchoring elements are generally matched to the elements to be fastened in such a way that they can easily be fastened.
    From CH 684 648 an anchoring system with an anchoring element in the form of a threaded sleeve with an elongated holding tube is known. The threaded sleeve is open on one side and closed on the opposite side by a cover plate. The threaded sleeve includes a central threaded hole into which a threaded bolt such as e.g. a tie rod can be screwed in. The holding tube is rotationally symmetrical, with the outside diameter gradually increasing from the open end to the closed end. The cover plate comprises circular ring sections which project radially beyond the holding tube.
    Such known threaded sleeves are fastened by means of peg-shaped mounting elements with a conical or frustoconical foot. Such assembly elements are attached to the formwork of a concrete structure to be created with a nail. After the nail has been driven in, a concrete sleeve to be fastened is placed on the pin and held there in a force-fitting manner. The pin serves on the one hand as a holding element for fastening the threaded sleeve and on the other hand at the same time closes the open side of the threaded bore. This is to prevent cement water from entering the threaded hole when the concrete structure is being built or when filling the formwork. After the construction has been completed and the concrete has hardened, the peg is removed from the threaded sleeve together with the formwork wall when the formwork is stripped, or, if the peg remains in the threaded sleeve, it can be pulled out of the threaded sleeve on the nail.
    When filling the formwork, the liquid concrete exerts forces on the threaded sleeve. These can cause the threaded sleeve to shift or become detached from the journal. As a result, cement water can penetrate the threaded hole and make the threaded sleeve unusable. Even if no cement water should penetrate, threaded sleeves that are cast in at an angle and / or offset with respect to the desired position after the concrete has hardened cannot be used. In particular, anchoring elements with comparatively large surfaces must therefore be additionally secured, for example by fastening them to reinforcing bars with wires. Conventional anchoring elements can also include nail loops, which additionally enable direct attachment to a formwork by means of nails.
    An object of the present invention is therefore to provide an anchoring system with an anchoring element that can be easily and reliably installed in a concrete structure.
    This object is achieved by an anchoring system and an anchoring element and a cover for this anchoring element according to the features of claims 1, 9 and 11.
    The anchoring system comprises an anchoring element with a wall that delimits a receiving space, and with an access opening to this receiving space and a lid with a base body and with an excellent on the base body, insertable in an insertion direction into the receiving space. The cover is a mounting element that is designed to attach an anchoring element to the formwork of a concrete part structure to be created. The cover is usually attached to the formwork with one or more nails. The anchoring element and the cover comprise mutually corresponding securing elements which, in a closed position, bring about a form-fitting connection of the cover to the anchoring element. In the closed position, the cover with the anchoring element is positively locked with respect to the direction of insertion and closes the access opening sufficiently tightly so that when the formwork is filled with liquid concrete, no cement water can get into the anchoring element.
    The securing elements comprise at least one elevation and / or depression on the inside of the wall of the receiving space and a corresponding depression or elevation on the outside of the pin. The anchoring element preferably comprises a section designed as a holding tube, at one end of which the access opening is formed. The securing elements of the anchoring element are in an input section close to the access opening, e.g. arranged in the foremost third of the holding tube, preferably in the area of the foremost 10 mm to 20 mm, and that of the cover correspondingly close to the base body. When the pin is inserted into the holding tube, the securing elements of each part therefore only come into contact with the other part of the anchoring system shortly before reaching the closed position. This facilitates the assembly of the parts and the risk of damage e.g. minimized by tilting or scraping.
    The lid is preferably an injection molded part made of plastic, the pin having a cavity within a pin wall. This minimizes the material requirement and gives the pin wall a freedom of movement for slight elastic deformations when inserted into the holding tube. This is particularly advantageous when on
    CH 714 848 A2 of the pin wall meet excellent locking or securing elements when inserted into the holding tube on corresponding securing elements of the anchoring element. When a sufficiently high force is exerted on the pin in the direction of insertion, the pin wall is elastically deformed slightly towards the cavity. Alternatively or additionally, the securing elements themselves can also be designed as elastically resilient latching elements on the pin wall. As a result, the securing elements can overcome the obstacle or the front area of the corresponding securing elements on the holding tube and can then be positively locked with them. Securing elements can include, for example, elevations or outstanding areas, such as beads, bulges or ribs, and / or depressions, such as depressions, channels or grooves. Securing elements preferably comprise elongated elevations and / or depressions which are arranged transversely to the direction of insertion on the outside of the wall of the pin and on the inside of the holding tube. This enables comparatively high securing forces against the direction of insertion even with small protrusion heights of the elevations or depressions in the order of magnitude of 1 mm or less. Such securing elements can extend like a ring over the entire inner or outer lateral surface of the respective part or alternatively only along one or more sections thereof.
    In embodiments with a round cross-section of the pin and the holding tube, securing elements can e.g. comprise one or more sectors with ribs or threaded sections and adjacent sectors without such structures. A cover with such a pin can be easily attached to the holding tube by pushing the pin axially or in the insertion direction into the holding tube and then rotating it by a small angle such that the securing elements on the two parts are at least partially form-fitting with respect to the insertion direction undercut.
    In other embodiments, the holding tube and the pin can also have any other cross-sectional shapes, in particular a non-round, for example an at least approximately rectangular cross-section. In such embodiments, the securing elements are preferably arranged on one or both opposing longer wall sections of the holding tube and the pin.
    Anchoring elements can e.g. be made of plastic or metal, in particular from one or more formed sheet metal parts. Anchoring elements made of metal can additionally have a corrosion-inhibiting coating.
    The cover preferably comprises a rib projecting from the base body, which is arranged around the pin in such a way that, together with the pin and the base body, it forms a groove for receiving the foremost section of the holding tube at the access opening. The labyrinth seal thus formed additionally protects the anchoring element against the ingress of cement water when the concrete structure is being built. In further alternative embodiments, corresponding securing elements could additionally or alternatively also be arranged on the outside of the anchoring element and on the inside on a corresponding outer section of the cover. In particular, e.g. the above-mentioned rib of the labyrinth seal comprises one or more sections with protruding or recessed heels transverse to the direction of insertion.
    In further embodiments, the cover can be designed as a collar with a central opening. Optionally, a locking element such as a locking plate must be permanently or releasably non-positively, positively or materially connected to the collar and thus close the central opening. The connection area can e.g. fully or partially designed as a separable vulnerability. Examples of this are thin, film-like connections and / or connections with perforations.
    The collar and / or the closing element preferably comprise additional connecting means such as e.g. Eyelets that facilitate attachment to formwork. Collar-like covers with or without a closing element can be positively connected to an anchoring element in the same way as closed covers.
    Collar-like covers made of plastic, which are connected to an anchoring element in the area of the access opening, can be designed, for example, such that they remain in the finished concrete component together with the anchoring element after the formwork has been removed. In this way, they protect the open entrance area of the anchoring element and form a visually perfect finish. Closing elements and / or parts of such covers connected to the formwork can be separated comparatively easily from the collar when or after the formwork is removed.

    1 to 6 relate to a first embodiment of an anchoring system comprising an anchoring element 1 with a holding tube 3, the lower end of which is closed by a cover plate 5, and a cover 51 with a pin 53 connected to a base body 55 protrudes. The cover plate 5 is round and comprises three ring sections projecting radially beyond the holding tube 3. The holding tube 3 comprises an access opening 7 at the front end, which can be used to insert the end of a tension rod or a corresponding other connecting element (not shown) into the receiving space delimited by the wall of the holding tube 3. Three reinforcing ribs 9 projecting radially on the holding tube 3 extend from the cover plate 5 to the front edge of the holding tube 3. In the region of the access opening 7, a recess 11 is formed between the holding tube 3 and each of the reinforcing ribs 9. The holding tube 3 comprises an internal thread 13 for fastening Dyvidag rods. Alternatively or additionally, other means for attaching other connection elements can also be provided in the receiving space or in the interior of the holding tube 3. On the inside of the holding tube 3, a primary securing element 15 is formed within an axial distance s1 from the front end of the holding tube 3. The distance s1 is preferably less than or equal to 20 mm or particularly preferably less than or equal to 10 mm. In this embodiment, the primary securing element 15 comprises a circumferential rib, which has a trapezoidal cross section and a protrusion height s2 of preferably less than 1 mm. The angle of inclination of the legs with respect to the inner wall of the holding tube 3 is a determining factor for the holding force of the fuse. This angle of inclination is preferably in the range from approximately 15 ° to approximately 75 °. In other embodiments, the primary securing element 15 can be circumferential in an analogous manner
    CH 714 848 A2
    Include groove with a depth of preferably less than 1 mm. A combination of a rib and a groove arranged axially or offset in the direction of insertion Z is also possible. The rib and / or the groove can also have a different, for example an arched, cross-sectional shape. It is essential that corresponding securing elements 15, 57 have contact areas which are opposite each other in the closed position in such a way that they form-fit an obstacle to movements of the cover 51 against the insertion direction Z. The primary securing elements 15 can alternatively also be formed on only one or more sections along the inner lateral surface of the holding tube 3.
    The cover 51 has the shape of a truncated cone, the pin 53 protruding coaxially on the top surface 56 of this truncated cone. In a base section 58 adjoining the base body 55, the pin 53 has an outer diameter d1 which essentially corresponds to the inner diameter of the holding tube 3 in the region of the access opening 7. Adjacent to the base section 58, the pin 53 has a smaller outside diameter d2, which essentially corresponds to the smaller inside diameter of the holding tube 3 in the area of the inside thread 13. As a secondary securing element 57, the pin 53 on the base section 58 comprises a circumferential groove. The position and shape of this groove or of the secondary securing element 57 is matched to the position and shape of the primary securing element 15 in such a way that these securing elements 15, 57 interlock positively with respect to the insertion direction Z when the cover 51 is in a closed position on the anchoring element 1 is held. In the closed position, the front end of the holding tube 3 bears against the cover surface 56 of the base body 55.
    In addition, axially aligned longitudinal beads 59 can be formed on the outside of the pin 53 for the positive connection of the pin 53 to the holding tube 3 in the area of the internal thread 13. The thickness of these longitudinal beads 59 is smaller than the width of the shoulder between the base section 58 and the adjoining one Section of the pin 53.
    Optionally, such longitudinal beads 59 or corresponding longitudinal ribs could also be made thicker in the area of the base body 55 and secondary securing elements 57 could be arranged on these longitudinal beads 59, for example in the form of shoulders (not shown).
    The cover 51 preferably comprises a collar 61 which projects coaxially to the pin 53 on the cover surface 56 of the base body 55 and, together with the wall of the pin 53, delimits a receiving groove 63. In the closed position, the receiving groove 63 receives the open front end of the holding tube 3 (FIG. 6) and forms a labyrinth seal with it. The interlocking areas of the securing elements 15, 57 form a further labyrinth seal in addition to their securing function.
    7 to 10 show a slightly modified embodiment of the anchoring system. In contrast to the embodiment according to FIGS. 1 to 6, the secondary securing element 57 on the cover 51 does not comprise a circumferential groove, but three or more cams 60 axially protruding on the base section 58, each with a groove section. The cams 60 are optionally arranged between two longitudinal beads 59.
    11 to 15 show a further embodiment of the anchoring system. In contrast to the previously described embodiments, the pin 51 has no enlarged outer diameter in the base region. The secondary securing elements 57 are three rib sections which protrude between three longitudinal beads 59 transversely to the axial direction on the outside of the holding tube 3. FIG. 13 shows the cover 51 cut open along the line B-B in FIG. 12 at the level of the secondary securing elements 57 in a perspective view. FIG. 15 shows a side view of the anchoring element 1 cut along the line C-C in FIG. 14. As the primary securing element 15, the holding tube 3 comprises a groove embedded in the uppermost section of the threaded rib of the internal thread 13.
    16 to 21 show a further embodiment of the anchoring system, the cover 51 being open in FIGS. 16 to 18 and in FIGS. 19 to 21 in the closed position. The anchoring element 1 comprises two formed sheet metal parts which are joined together in such a way that they delimit a receiving space, this receiving space comprising a section with an approximately rectangular cross section as a holding tube 3. Each of the two longer side walls of the holding tube 3 comprises, as the primary securing element 15, an inwardly shaped rib-like bead, which is preferably arranged within a distance s1 of approximately 10 mm to approximately 20 mm from the open tube end transverse to the insertion direction Z or parallel to the edge of the respective side wall is. The cover 51 comprises a base body 55 in the form of a rectangular plate and a pin 53 protruding from this plate, the wall of which comprises four wall sections which form a rectangular frame. The two longitudinal walls comprise, as secondary securing elements 57, elongated concavities which are arranged and aligned in such a way that they receive the primary securing elements 15 of the anchoring element 1 when the cover 51 is in the closed position. Analogous to the other embodiments of the anchoring system, the cover 51 comprises a collar 61 which, together with the wall of the pin 53, delimits a circumferential receiving groove 63. In the closed position, the receiving groove 63 receives a section of the open front end of the holding tube 3 and forms a labyrinth seal with it. Analogous to the longitudinal beads 59 in the other embodiments, longitudinal beads 59 or longitudinal ribs for longitudinally connecting the cover 51 to the anchoring element 1 can be formed on the outside of the pin 53 in the other embodiments. The protruding height of these longitudinal ribs preferably increases slightly in the direction of the base body 55. This causes an increasing holding force when the cover is pressed into the closed position in the direction of insertion Z. A further anchoring system according to FIGS. 22 to 27 essentially differs from that according to FIGS. 16 to 21 in that the primary securing elements 15 on the side walls of the holding tube 3 are directed outwards
    CH 714 848 A2 are domed areas, and that the secondary securing elements 57 are one or more cams outstanding on the outer sides of the pin 53.
    In general, stops 15a of the primary securing elements 15 and stops 57a of the secondary securing elements 57 with respect to the insertion direction Z in the closed position hold is dependent on the angles of inclination a, β of the stops 15a, 57a or at least a portion of these stops 15a, 57a with respect to the respective wall of the anchoring element 1 or the pin 53 and thus also with respect to the insertion direction Z. A particularly high securing force can be achieved if each of the angles of inclination a, ß is 90 ° or smaller. At least one of the angles of inclination α, β is preferably between 75 ° and 90 °.
    FIG. 28 shows an example of a detailed cross section of such an arrangement in the closed position, the secondary securing element 57 being arranged on a resilient section of the wall.
    Preferably, the wall of the anchoring element 1 in the area of the access opening 7 comprises at least one section in which the opening cross section of the receiving space widens towards the access opening 7. In this section, the wall of the anchoring element 1 can, for example, have an internal chamfer and / or be deformed outwards. This can prevent secondary securing elements 57 of the pin 53 from being damaged when the pin 53 is inserted into the anchoring element 1 in the insertion direction Z.
    29 schematically shows a detailed cross section of a special embodiment of a cover 51. The base body 55 comprises a collar 59 which frames a central opening. This central opening is closed by a plate-shaped closing element 61, the edge of this closing element 61 e.g. is permanently or releasably non-positively, positively or cohesively connected to the collar 59.
    In particular, the connection e.g. comprise a film hinge 63 which is thin in comparison to the adjacent regions of the base body 55 and / or perforated regions. The connection of the closing element 61 to the collar 59 can generally be designed as a weak point. After the formwork has been removed from a finished concrete structure, the closing element 61 can accordingly be separated from the adjacent collar 59 when the force is sufficiently high.
