Description
Befestigungsanker für Arbeiten an einer Betonwand oder -decke. Fastening anchors for working on a concrete wall or ceiling.
Die Erfindung betrifft einen Befestigungsanker zur Durchführung von Arbeiten an einer Betonwand oder Betondecke. Insbesondere ist dabei an die Abschalung von Decken oder Böden gedacht, die auf Betonwände aufgesetzt werden. Ein solcher Befestigungsanker kann aber auch in Verbindung mit abgehängten Decken oder zur Befestigung von Rohrleitungen an Betonwänden oder Betondecken benutzt werden.The invention relates to a fastening anchor for performing work on a concrete wall or concrete ceiling. In particular, the formwork of ceilings or floors that are placed on concrete walls is considered. Such anchoring anchors can also be used in connection with suspended ceilings or for attaching pipelines to concrete walls or concrete ceilings.
Bisher war es üblich, in die Betonwand, auf die beispielsweise eine Decke aufgesetzt werden soll, Stahlstifte oder Drähte einzubetonieren, die dann für die Halterung der Deckenschalung benutzt wurden. Diese Arbeitsweise weist mehrere Nachteile auf. Nach der Entfernung der Deckenschalung müssen die frei herausstehenden Enden der Stahlstifte oder Drähte abgezwickt werden und zwar so sauber, daß sie die Betonfläche nicht mehr überragen. Einerseits können aus einer Betonmauer herausstehende Drahtenden - auch wenn sie noch so kurz sind - zu Verletzungen der Bauarbeiter führen, andererseits bilden aber solche herausstehenden Stahlstifte oder Drahtenden einen störenden An
blick, was insbesondere bei Sichtbeton zu beachten ist. Es kommt hinzu, daß das Abzwicken dieser Stahlstifte oder Drähte nach der Ausschalung der Betonmauer zeitraubend und damit kostspielig ist.So far, it has been customary to concrete steel pins or wires into the concrete wall, on which a ceiling is to be placed, for example, which were then used to hold the ceiling formwork. This way of working has several disadvantages. After removing the slab formwork, the protruding ends of the steel pins or wires must be pinched off and so clean that they no longer protrude from the concrete surface. On the one hand, wire ends protruding from a concrete wall - even if they are so short - can lead to injuries to the construction workers, but on the other hand such protruding steel pins or wire ends are a nuisance view, which is particularly important for exposed concrete. In addition, the pinching off of these steel pins or wires after stripping the concrete wall is time-consuming and therefore expensive.
Zu diesen Nachteilen tritt noch die Tatsache, daß die herausstehenden Drahtenden oder Stifte - auch wennsie abgezwickt sind - Rost ansetzen. Herablaufendes Regenwasser kann damit auf der Betonmauer rostige Streifen hinterlassen, so daß die Mauer sehr bald unansehlich wird. Jedenfalls wäre eine solche Mauer in Sichtbetonweise praktisch nicht ausführbar.In addition to these disadvantages, there is the fact that the protruding wire ends or pins, even if they are pinched off, become rusty. Running rainwater can leave rusty stripes on the concrete wall, so that the wall will soon become unsightly. In any case, such a wall would not be practically practicable in exposed concrete.
Zur Vermeidung der erwähnten Nachteile ist bereits ein Befestigungsanker bekannt, welcher aus einer in die Betonwand einbetonierbaren Hülse mit einem die Hülse quer zu ihrer Längsrichtung durchdringenden Verankerungsstift aus Stahl besteht; dieser Verankerungsstift dient seinerseits als Anker für ein in das Hülseninnere einzuführendes ösenartiges Befestigungsglied. Nach Fertigstellung der Betonmauer weist diese somit eine Reihe von durch die eingesetzten Hülsen sich ergebenden Öffnungen auf, in welche ösenartige Befestigungsglieder eingehängt werden, so daß dann diese Ösen zur Halterung der Verschalungsbretter benutzbar sind.In order to avoid the disadvantages mentioned, a fastening anchor is already known, which consists of a sleeve which can be concreted into the concrete wall and has an anchoring pin made of steel which penetrates the sleeve transversely to its longitudinal direction; this anchoring pin in turn serves as an anchor for an eyelet-like fastener to be inserted into the interior of the sleeve. After completion of the concrete wall, it thus has a series of openings resulting from the inserted sleeves, into which eyelet-like fastening elements are hung, so that these eyelets can then be used to hold the shuttering boards.
Wenngleich diese Art eines Befestigungsankers bereits einen Fortschritt gegenüber den eingangs erwähnten Befestigungsmethoden für Schalbretter darstellt, liegt der Erfindung die Aufgabe zugrunde, dieses bekannte Hülsenprinzip so zu verbessern, daß die Einzelteile des Befestigungsankers preiswerter und stabiler herstellbar sind.
Ausgehend von dem bekannten Befestigungsanker, welcher aus einer in die Betonwand oder -decke einbetonierbaren, mit einem Verankerungselement versehenen Hülse und einem in die einbetonierte Hülse einführbaren und in dem Verankerungselement der Hülse arretierbaren Befestigungsglied besteht, wird gemäß der Erfindung vorgeschlagen, daß die Hülse einen ersten Abschnitt mit einem im wesentlichen schlitzförmigen Querschnittsprofil und einen sich daran anschließenden, als Verankerungselement dienenden zweiten Abschnitt mit einem erweiterten, vorzugsweise kreisförmigen oder annähernd kreisförmigen Querschnittsprofil aufweist und daß das Befestigungsglied aus einem Stab oder Rohr besteht, welches an seinem in die Hülse einführbaren Ende einen oder mehrere, quer zur Längsrichtung des Stabes oder Rohres verlaufende, dem Schlitzprofil der Hülse angepaßte Verankerungsglieder aufweist und dessen anderes, aus der Hülse vorstehendes Ende für eine Klemm- oder Schraubverbindung geeignet ausgebildet ist.Although this type of fastening anchor already represents an advance over the fastening methods for formwork boards mentioned at the outset, the object of the invention is to improve this known sleeve principle in such a way that the individual parts of the fastening anchor can be manufactured more cheaply and more stably. Starting from the known fastening anchor, which consists of a concrete that can be concreted into the concrete wall or ceiling, is provided with an anchoring element and a insertable into the concreted sleeve and lockable in the anchoring element of the sleeve, it is proposed according to the invention that the sleeve is a first Section with an essentially slit-shaped cross-sectional profile and an adjoining, serving as anchoring element, second section with an expanded, preferably circular or approximately circular cross-sectional profile and that the fastening member consists of a rod or tube which has one or at its insertable end into the sleeve has several, transversely to the longitudinal direction of the rod or tube, the slot profile of the sleeve adapted anchoring members and the other, protruding from the sleeve end for a clamp or screw connection gnet is trained.
Soll mit dem Befestigungsglied eine Klemmverbindung durchführbar sein, so wird sein aus der Hülse herausstehendes Ende zweckmäßig ösenförmig, z. B. zum Einpressen eines Keiles, ausgebildet. Im Falle einer Schraubverbindung weist das aus der Hülse herausstehende Ende des Befestigungsgliedes ein Innen- oder Außengewinde auf.If a clamping connection can be carried out with the fastening member, its end protruding from the sleeve is expediently eyelet-shaped, for. B. for pressing a wedge. In the case of a screw connection, the end of the fastening member protruding from the sleeve has an internal or external thread.
Zur besseren Verankerung der Hülse im Beton empfiehlt es sich, sie an ihrem Ende, nämlich an dem Teil, welcher kreisförmiges oder annähernd kreisförmiges Querschnittsprofil aufweist, mit einem Verstärkungsflansch zu versehen.
Ferner empfiehlt es sich, denjenigen Hohlraum der Hülse, welcher kreisförmiges oder annähernd kreisförmiges Querschnittsprofil aufweist, mit einem oder mehreren querstehenden Begrenzungslappen zu versehen, welche dann als Anschlag für die Drehbewegung des einzuführenden Befestigungsgliedes dienen.For better anchoring of the sleeve in the concrete, it is advisable to provide it with a reinforcing flange at its end, namely on the part which has a circular or approximately circular cross-sectional profile. Furthermore, it is advisable to provide that cavity of the sleeve, which has a circular or approximately circular cross-sectional profile, with one or more transverse limiting tabs, which then serve as a stop for the rotational movement of the fastening element to be inserted.
Die Hülse selbst wird zweckmäßig aus Kunststoff und zwar im Spritzgußverfahren hergestellt. Sie wird beiderseits mit Akschlußdeckeln versehen, welche den jeweiligen Querschnittprofilen angepaßt sind.The sleeve itself is expediently made of plastic, namely by injection molding. It is provided with access covers on both sides, which are adapted to the respective cross-sectional profiles.
Gegenüber dem bekannten, aus Hülse und Befestigungsglied bestehenden Befestigungsanker weist der erfindungsgemäße den Vorteil auf, daß durch das schlitzförmige Profil des vorderen Teiles der Hülse nur eine kleinere Öffnung in der Betonwand entsteht als bei der bekannten Anordnung. Da die mittige Ausbuchtung des Schlitzes nur so groß zu sein braucht, daß der Schaft des Befestigungsgliedes etwa ein Spiel von 1 mm hat, ist darüber hinaus gleichzeitig eine Führung für das Befestigungsglied innerhalb der Hülse gegeben.Compared to the known fastening anchor consisting of a sleeve and a fastening element, the invention has the advantage that the slot-shaped profile of the front part of the sleeve only results in a smaller opening in the concrete wall than in the known arrangement. Since the central bulge of the slot only needs to be so large that the shaft of the fastening element has about a play of 1 mm, a guide for the fastening element is also provided inside the sleeve.
Das in die Hülse einzuführende Befestigungsglied wird zweckmäßig aus Temperguß hergestellt. Naturgemäß wäre es aber auch möglich, dieses Glied aus normalem Stahl herzustellen oder sogar aus Flacheisen, wobei man im letzteren Falle das Stanzverfahren bei der Herstellung anwenden würde. Als Ausgangsmaterial hierfür könnte man 5 - 10 mm starkes Flacheisen verwenden.The fastener to be inserted into the sleeve is expediently made of malleable cast iron. Naturally, it would also be possible to produce this link from normal steel or even from flat iron, in which case the stamping method would be used in the production. 5 - 10 mm thick flat iron could be used as the starting material for this.
Eine besonders kostengünstige Herstellung für ein eine Schraubverbindung zulassendes Befestigungsglied würde
sich dann ergeben, wenn man dieses Glied zweiteilig ausbildet, derart, daß ein Teil das Verankerungsglied aufweist und das andere Teil aus einem üblichen Gewinde-Spannstab für Betonschalung besteht. Wenn man dann das erstgenannte Teil mit einer axialen Gewindebohrung versieht, kann man dieses Teil mit dem GewinderSpannstab verschrauben. Der Vorteil dieser Herstellungsmethode besteht darin, daß lediglich das erstgenannte Teil, welches also das Verankerungsglied aufweist, aus Temperguß hergestellt werden müßte.A particularly cost-effective production for a fastener permitting a screw connection would arise when this link is formed in two parts, such that one part has the anchoring member and the other part consists of a conventional threaded tie rod for concrete formwork. If you then provide the first-mentioned part with an axial threaded hole, you can screw this part with the threaded tie rod. The advantage of this manufacturing method is that only the first-mentioned part, which therefore has the anchoring member, would have to be made from malleable cast iron.
Ausführungsbeispiele für den neuerungsgemäßen Befestigungsanker, worunter die einzubetonierende Hülse mit dem zugehörigen Befestigungsglied verstanden werden soll, sind in den Zeichnungen dargestellt.Exemplary embodiments of the fastening anchor according to the innovation, which is to be understood as meaning the sleeve to be concreted in with the associated fastening member, are shown in the drawings.
In Fig. 1 der Zeichnung ist eine Seitenansicht, in Fig. 2 eine Aufsicht der prinzipiellen Ausbildung der Hülse wiedergegeben. Fig. 3 stellt eine Ansicht einer Ausführung des Befestigungsgliedes dar, während in Fig. 4 das Prinzip der Anwendung dieses Befestigungsankers zur Verschalung einer Betonwand unter Anwendung einer Klemmverbindung wiedergegeben ist. In den Fig. 5 und 6 sind perspektivische Darstellungen der Befestigungshülse gezeichnet, in Fig. 7 ein anders ausgebildetes Befestigungsglied und in Fig. 8 ist dargestellt, in welcher Weise bei der Verschalung einer Betonwand ein solcher Befestigungsanker mit einem Befestigungsglied nach Fig. 7 anzuwenden ist.In Fig. 1 of the drawing is a side view, in Fig. 2 is a plan view of the basic design of the sleeve. Fig. 3 shows a view of an embodiment of the fastener, while in Fig. 4 the principle of the use of this fastening anchor is shown for formwork of a concrete wall using a clamp connection. 5 and 6, perspective representations of the fastening sleeve are drawn, in FIG. 7 a differently designed fastening element and in FIG. 8 it is shown how such a fastening anchor with a fastening element according to FIG. 7 is to be used when formworking a concrete wall .
In Fig. 1 und 2 ist die in die Mauer einzubetonierende Hülse mit 13 bezeichnet. Sie besteht aus den beiden Abschnitten 1 und 2, welche ineinander übergehen.
Diese beiden Abschnitte unterscheiden sich voneinander durch ihr Profil. Das Profil des Abschnittes 1 ist etwa schlitzförmig ausgebildet, wie sich aus Fig. 2 ergibt. Das sich anschließende Profil 2 ist dagegen kreisförmig oder annähernd kreisförmig ausgebildet. Beide sich ergebende Öffnungen der Hülse 13 sind durch die Deckel 3 bzw. 3a abgedeckt. Während der Deckel 3a lediglich die Aufgabe hat, die Hülse 13 gegen das Eindringen von Beton zu verschließen, wird der Deckel 3 dazu benutzt, um die Hülse 13 während des Betoniervorganges zu halten. Dementsprechend weist der Deckel 3 eine Stärke von etwa 20 mm auf. Er wird mit Hilfe von Stiften oder Nägeln an dem Verschalungsbrett befestigt, anschließend wird die Hülse auf den Deckel 3 aufgesteckt.1 and 2, the sleeve to be concreted into the wall is designated 13. It consists of the two sections 1 and 2, which merge into one another. These two sections differ from each other in their profile. The profile of section 1 is approximately slot-shaped, as can be seen in FIG. 2. The adjoining profile 2, on the other hand, is circular or approximately circular. Both resulting openings of the sleeve 13 are covered by the cover 3 and 3a. While the cover 3a only has the task of closing the sleeve 13 against the penetration of concrete, the cover 3 is used to hold the sleeve 13 during the concreting process. Accordingly, the cover 3 has a thickness of approximately 20 mm. It is attached to the formwork board with the help of pins or nails, then the sleeve is attached to the cover 3.
Aus Fig. 3 ist die Ausbildung eines ösenartigen Befestigungsgliedes 14 zu erkennen, welches in die einbetonierte Hülse 13 eingesteckt wird. Dieses Glied besteht aus dem Osenteil 5, einem Schaft 6 sowie einem Verankerungsstift 7. Wie in der Zeichnung dargestellt, kann man diese Teile einzeln herstellen und dann zusammenbauen, beispielsweise dadurch, daß der rohrförmige Schaft 6 in das Osenteil 5 eingeschweißt wird und daß anschließend der Stift 7 in eine Bohrung des Schaftes 6 eingeschlagen wird. In der Massenfertigung wird man jedoch zweckmäßig das in Fig. 3 dargestellte Teil in einem Arbeitsgang, beispielsweise im Temperguß herstellen.From Fig. 3 the formation of an eyelet-like fastening member 14 can be seen, which is inserted into the concreted-in sleeve 13. This link consists of the eyelet 5, a shaft 6 and an anchoring pin 7. As shown in the drawing, these parts can be manufactured individually and then assembled, for example by welding the tubular shaft 6 into the eyelet 5 and then the Pin 7 is driven into a bore in the shaft 6. In mass production, however, the part shown in FIG. 3 will expediently be produced in one operation, for example in malleable cast iron.
In Fig. 4 ist die Anwendung eines aus den in Fig. 1, 2 und 3 dargestellten Teilen bestehenden Befestigungs
ankers erläutert. In die in die Betonmauer 8 einbetonierte Hülse 13 wird das ösenartige Befestigungsglied 14 eingesteckt wie beispielsweise ein Schlüssel in ein Schlüsselloch. Nach dem Einführen dieses Gliedes wird es um 90° gedreht, so daß der Verankerungsstift 7 in dem Hülsenteil 2 arretiert wird. Anschliessend kann dann das Schalbrett 10 an die Betonwand 8 angesetzt und unter Verwendung eines weiteren Abstands stückes 15 und einer U-Schiene 11 unter Verwendung eines in das Osenteil 5 eingesteckten Keils 12 festgekeilt werden.In Fig. 4 is the application of an attachment consisting of the parts shown in Figs. 1, 2 and 3 anchor explained. The eyelet-like fastening member 14 is inserted into the sleeve 13 concreted into the concrete wall 8, such as a key in a keyhole. After insertion of this link, it is rotated by 90 °, so that the anchoring pin 7 is locked in the sleeve part 2. Then the formwork board 10 can then be attached to the concrete wall 8 and wedged using a further spacer 15 and a U-rail 11 using a wedge 12 inserted into the outer part 5.
Naturgemäß kann man auch erst das Schalbrett 10 an die Betonwand 8 anlegen, dann das Befestigungsglied 14 durch die im Schalbrett 10 vorgesehene Bohrung in die Hülse 13 einführen und um 90° drehen und schließlich das Schalbrett 10 mit Hilfe der U-Schiene 11 und dem Keil 12 in der Öse 5 des Befestigungsgliedes 14 verkeilen.Of course, you can also first put the formwork board 10 on the concrete wall 8, then insert the fastener 14 through the hole provided in the formwork board 10 in the sleeve 13 and rotate 90 ° and finally the formwork board 10 with the help of the U-rail 11 and the wedge Wedge 12 in the eyelet 5 of the fastener 14.
Nach Vergießen der auf die Betonwand aufzusetzenden Decke wird der Keil 12 herausgeschlagen, so daß das Schalbrett 10 abgenommen werden kann. Anschließend wird das ösenartige Befestigungsglied 14 durch Drehung um 90° aus der Hülse herausgenommen sowie die Hülsenöffnung mit Hilfe der Abdeckung 3 verschlossen.After pouring the ceiling to be placed on the concrete wall, the wedge 12 is knocked out so that the formwork board 10 can be removed. Subsequently, the eyelet-like fastening member 14 is removed from the sleeve by rotation through 90 ° and the sleeve opening is closed with the aid of the cover 3.
In den Fig. 5 und 6 sind perspektivische Darstellungen der in den Figuren 1 und 2 in Ansicht dargestellten Hülse gezeichnet und zwar in einem gegenüber den Fig. 1 und 2 verkleinerten Maßstab.
In Fig. 7 ist eine andere Ausführungsform eines Befestigungsgliedes gezeichnet und in Fig. 8 die Anbringung einer Verschalung mit einem solchen Befestigungsglied.5 and 6 are perspective representations of the sleeve shown in FIGS. 1 and 2 in a view drawn on a smaller scale than in FIGS. 1 and 2. In Fig. 7 another embodiment of a fastening member is drawn and in Fig. 8 the attachment of a casing with such a fastening member.
In den Fig. 5 und 6 sind noch Einzelheiten der Hülse 13 zu erkennen. So weist das kreisförmige Querschnittsprofil 2 an seinem äußeren Rand einen Verstärkungsflansch 16 auf. Im Inneren dieses kreisförmigen Querschnittsprofils sind ein oder mehrere Begrenzungslappen 17 vorgesehen, welche als Anschlag dienen. Die Hülse ist an beiden offenen Seiten mit Kappen 3 bzw. 3a versehen, deren Form den Querschnittsprofilen angepaßt sind.5 and 6 details of the sleeve 13 can still be seen. For example, the circular cross-sectional profile 2 has a reinforcing flange 16 on its outer edge. In the interior of this circular cross-sectional profile, one or more limiting tabs 17 are provided, which serve as a stop. The sleeve is provided on both open sides with caps 3 and 3a, the shape of which is adapted to the cross-sectional profiles.
In Fig. 7 ist eine Ausführungsform für das Befestigungsglied gezeichnet, welches nach dem Einbetonieren der in den Fig. 1, 2, 5 und 6 dargestellten Hülse in diese Hülse eingeführt wird. Dieses Befestigungsglied ist aus den beiden Teilen 18 und 19 zusammengesetzt, wobei das Teil 18 zweckmäßig im Temperguß hergestellt ist und an seinem Ende das Verankerungsglied 20 trägt. Der Durchmesser des Schaftes 18 muß kleiner sein als der Innendurchmesser 4 des Hülsenteiles 1 (Fig. 2), damit dieses Teil nach seinem Einführen in dem schlitzförmigen Teil 1 der Hülse drehbar ist. Das Verankerungsglied 20 besitzt eine Spannbreite, welche geringer sein muß als der Innendurchmesser des kreisförmigen Hülsenteiles 2. Das Teil 18 des Befestigungsgliedes ist noch mit einer Innenbohrung und Innengewinde 21 versehen, so daß in dieses Teil ein üblicher Gewindespannstab 19 einschraubbar ist, der an seinen beiden Enden mit Außengewinde 22
und 23 versehen ist. Nach dem Zusammenschrauben der beiden Teile 18 und 19 wird dieses Befestigungsglied in die einbetonierte Hülse 13 eingeführt und um etwa 90° geschwenkt. Mit Hilfe des Verankerungsgliedes 20, welches bei der Sbhwenkung um etwa 90° an dem Anschlaglappen 17 anschlägt, ist das Befestigungsglied 18, 19 in der Hülse verankert und kann nunmehr zur Befestigung der anzulegenden Schalbretter dienen. Die Befestigung erfolgt dann mit Hilfe einer Flügelmutter 24, die in Fig. 7 ebenfalls dargestellt ist.In Fig. 7 an embodiment for the fastening member is drawn, which is inserted into this sleeve after concreting the sleeve shown in Figs. 1, 2, 5 and 6. This fastening member is composed of the two parts 18 and 19, the part 18 is expediently made in malleable cast iron and carries the anchoring member 20 at its end. The diameter of the shaft 18 must be smaller than the inner diameter 4 of the sleeve part 1 (FIG. 2) so that this part can be rotated after it has been inserted into the slot-shaped part 1 of the sleeve. The anchoring member 20 has a span, which must be less than the inner diameter of the circular sleeve part 2. The part 18 of the fastening member is also provided with an inner bore and internal thread 21, so that a conventional threaded tie rod 19 can be screwed into this part, which on both of its parts Male thread ends 22 and 23 is provided. After the two parts 18 and 19 have been screwed together, this fastening member is inserted into the concreted-in sleeve 13 and pivoted through approximately 90 °. With the help of the anchoring member 20, which abuts the stop tab 17 when the pivoting is about 90 °, the fastening member 18, 19 is anchored in the sleeve and can now be used to fasten the formwork boards to be applied. The attachment is then carried out using a wing nut 24, which is also shown in Fig. 7.
Die Arbeitsweise mit diesem Befestigungsanker ist in einem Ausführungsbeispiel in Fig. 8 dargestellt. Die Betonmauer ist wiederum mit 8 bezeichnet. Während des Gießens dieser Mauer ist die soeben beschriebene Hülse 13 einbetoniert worden. Die Befestigung der Holzschalung 10 erfolgt in diesem Fall mit einem Spannholz 11, welches an die Holzschalung 10 zusammen mit einem Abstandstück 15 angelegt wird. Durch eine Bohrung des Spannholzes 11 wird das Befestigungselement in die Hülse 13 eingeführt und um 90° gedreht, so daß das Verankerungsglied 20 des Befestigungsgliedes in der Hülse verankert ist. Mit Hilfe einer Flügelmutter 24 wird nunmehr das Spannholz 11 an die Holzschalung 10 angedrückt, so daß die Holzschalung 10 fest an der Betonwand 8 anliegt.The operation with this fastening anchor is shown in one embodiment in FIG. 8. The concrete wall is again designated 8. During the pouring of this wall, the sleeve 13 just described has been concreted. In this case, the wooden formwork 10 is fastened with a tensioning timber 11, which is applied to the wooden formwork 10 together with a spacer 15. The fastening element is inserted into the sleeve 13 and rotated through 90 ° through a bore in the tensioning timber 11, so that the anchoring member 20 of the fastening member is anchored in the sleeve. With the help of a wing nut 24, the tensioning timber 11 is now pressed onto the wooden formwork 10, so that the wooden formwork 10 lies firmly against the concrete wall 8.
Es sei abschließend darauf hingewiesen, daß man das Befestigungsglied, welches in Fig. 7 zweiteilig dargestellt ist, auch aus einem einzigen Stück herstellen kann. Die zweiteilige Herstellung hat jedoch den Vorteil, daß sie wesentlich billiger ist.
Wie sich aus dem Vorstehenden ergibt, stellt die einbetonierbare Hülse das wesentliche Element des erfindungsgemäßen Befestigungsankers dar. In den dargestellten Ausführungsbeispielen weist diese Hülse zwei Profile auf, deren erstes dem Einführen des eigentlichen Verankerungselementes dient, während das zweite Profil so ausgebildet ist, daß es die Arretierung dieses Befestigungselementes nach seinem Einführen in die Hülse bewirkt. Zu diesem Zweck ist bei dem dargestellten Ausführungsbeispiel das Befestigungselement mit einem quer zu seiner Längsrichtung verlaufenden Verankerungsstift versehen, so daß dieses Befestigungselement nach seinem Einführen in die Hülse um beispielsweise 90º verdreht werden muß, um in die Verankerung einzurasten.It should finally be pointed out that the fastening element, which is shown in two parts in FIG. 7, can also be produced from a single piece. However, the two-part production has the advantage that it is much cheaper. As can be seen from the above, the concretable sleeve is the essential element of the fastening anchor according to the invention. In the illustrated embodiments, this sleeve has two profiles, the first of which is used to insert the actual anchoring element, while the second profile is designed so that it Locking this fastener after it is inserted into the sleeve. For this purpose, in the illustrated embodiment, the fastener is provided with an anchoring pin extending transversely to its longitudinal direction, so that after it has been inserted into the sleeve, this fastener must be rotated, for example, by 90 ° in order to engage in the anchoring.
Eine diesem Grundgedanken entsprechende andere Ausführungsform der Erfindung würde darin besteht, daß man die in den Fig. 1, 2, 5 und 6 dargestellte profilierte Hülse in der Weise abändert, daß das Profilteil 1 zur Mittelachse der Hülse unsymmetrisch verläuft. Die eine Seite des dargestellten Profils fällt weg, so daß das Profilteil 1 eine Öffnung etwa entsprechend der Öffnung eines Schlüsselloches aufweist. Wenn mann nun dem stabförmigen Befestigungsglied einen Durchmesser gibt, der etwas geringer ist als die Breite des Schlitzes des Profils 1 und wenn man diesen Stab an seinem Ende zu einer Wulst verdickt, welche etwas geringeren Durchmesser aufweist als der Durchmesser 4 gemäß Fig. 2, so kann man dieses Befestigungsglied in die Hülse einführen und zwar soweit, daß das verdickte Ende dieses Befestigungs
gliedes in das hintere Profilteil 2 der Hülse hineinragt. Wenn dieses Befestigungsglied nunmehr in Schlitzrichtung soweit verschoben wird, daß der Stab in den Schlitz hereinfällt, so ist dieses Befestigungsglied gegen Herausfallen aus der Hülse gesichert, weil seine Endverdickung in dem Profilteil 2 verankert ist. Diese Ausführung hätte den Vorteil, das man für das Befestigungsglied handelsübliche Teile verwenden könnte.Another embodiment of the invention corresponding to this basic idea would consist in changing the profiled sleeve shown in FIGS. 1, 2, 5 and 6 in such a way that the profile part 1 runs asymmetrically to the central axis of the sleeve. One side of the profile shown is omitted, so that the profile part 1 has an opening approximately corresponding to the opening of a keyhole. If you now give the rod-shaped fastening member a diameter that is slightly less than the width of the slot of the profile 1 and if you thicken this rod at its end to a bead which has a slightly smaller diameter than the diameter 4 according to FIG. 2, so you can insert this fastener into the sleeve, to the extent that the thickened end of this attachment limb protrudes into the rear profile part 2 of the sleeve. If this fastener is now moved so far in the slot direction that the rod falls into the slot, this fastener is secured against falling out of the sleeve because its final thickening is anchored in the profile part 2. This version would have the advantage that you could use commercially available parts for the fastener.
Man kann den erfindungsgemäßen Befestigungsanker auch in Verbindung mit abgehängten Decken oder zur Befestigung von Rohrleitungen an Betondecken benutzen. In diesem Fall wäre die Verwendung eines Befestigungsgliedes gemäß Fig. 7 zweckmäßig. Der Schaft 19 müßte dann allerdings eine größere Länge aufweisen, um nach dem Einführen in die einbetonierte Hülse genügend weit herauszustehen.
The fastening anchor according to the invention can also be used in connection with suspended ceilings or for fastening pipes to concrete ceilings. In this case, the use of a fastening element according to FIG. 7 would be expedient. However, the shaft 19 would then have to have a greater length in order to protrude sufficiently far after being inserted into the concreted-in sleeve.
