Die Erfindung bezeichnet einen Eingussdübel zur gegenseitigen zugfesten Verbindung zweier Festkörper im Beton-Beton-Verbund.The invention relates to a pouring dowel for mutual tensile connection two solid bodies in a concrete-concrete composite.
Beim Beton-Beton-Verbund ist der Eingussdübel mit seinem Befestigungsteil über ein temporär fliessfähiges, aushärtbares Befestigungsmittel wie Reaktionsharzmörtel in einem Sackloch im ersten Festkörper wie Altbeton befestigbar und mit seinem radial auskragenden Einbettungsteil in diesem, zeitlich später aushärtenden, zweiten Festkörper wie Neubeton fliessfähig einbettbar.In the concrete-concrete composite, the pouring dowel with its fastening part is over one Temporary flowable, hardenable fasteners such as reactive resin mortar in one Blind hole can be fastened in the first solid like old concrete and with its radially projecting Embedding part in this, later hardening, second solid like new concrete flowable embeddable.
Als Eingussdübel werden üblicherweise am Einsatzort abgewinkelte oder endseitig konisch aufgestauchte, vorgefertigte Armierungseisen sowie am Einsatzort mit Gewindestangen kombinierte Gewindeplatten verwendet. Diese Eingussdübel sind hinsichtlich der Auszugsfestigkeit des Einbettungsteils aus dem Neubeton beziehungsweise der Zugkrafteinleitung in diesen sowie der Zugsteifigkeit nicht optimal ausgestaltet.As dowels, angled or conical ends are usually used on site upset, prefabricated reinforcing bars and on-site with threaded rods combined thread plates used. These dowels are regarding Pull-out strength of the embedding part from the new concrete or The introduction of tensile force in these and the tensile rigidity are not optimal.
Nach der WO99/61716 wird eine auf eine Gewindestange aufgeschraubte Konuskappe in Neubeton eingebettet, wobei die Konuskappe endseitig mit der Neubetonoberfläche bündig abschliesst und nur bezüglich der schlechthaftenden Kegelstumpffläche mit dem Neubeton abbindet. Die Konuskappe bildet bei einem axialen Halbwinkel von 15° längs ihrer axialen Länge eine doppelte radiale Überhöhung aus. Diese Konuskappe ist nicht zur Krafteinleitung optimiert sondern dient als axial leicht über die Neubetonoberfläche entfernbare Blindform.According to WO99 / 61716, a cone cap screwed onto a threaded rod New concrete embedded, with the cone cap flush with the new concrete surface closes and only with regard to the poorly adhering truncated cone surface with the new concrete sets. The conical cap forms at an axial half angle of 15 ° along its axial Length a double radial cant. This cone cap is not for force application optimized but serves as a blind form that can be easily removed axially from the new concrete surface.
Nach der CH684648A5 werden Gewindehülsen aus Kunststoff mit umfänglich verteilten Konusrippen mit einem axialen Halbwinkel von 45° und doppelter radialer Überhöhung längs ihrer axialen Länge in Neubeton eingebettet. In Gewindehülsen aus Kunststoff sind nur geringe Zugkräfte einleitbar.According to CH684648A5, threaded sleeves made of plastic are distributed over the entire circumference Taper ribs with an axial half angle of 45 ° and double radial elevation along their axial length embedded in new concrete. In plastic threaded sleeves are only low tensile forces can be introduced.
Des weiteren werden nach der DE2355799 in Neubeton eingebettete gewellte Rohrstücke über Gewinde mit anderen Bauteilen kombiniert. Furthermore, according to DE2355799, corrugated pipe sections are embedded in new concrete combined with other components via thread.
Die Aufgabe der Erfindung besteht in der technologisch einfachen Realisierung eines Eingussdübels mit hinsichtlich Zugkrafteinleitung und Zugsteifigkeit optimierter Geometrie.The object of the invention is the technologically simple implementation of a Socket anchor with geometry optimized with regard to the introduction of tensile force and tensile rigidity.
Die Aufgabe wird im wesentlichen durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The task is essentially solved by the features of the independent claims. Advantageous further developments result from the subclaims.
Im wesentlichen weist ein Eingussdübels mit einem, über ein temporär fliessfähiges, aushärtbares Befestigungsmittel in einem Sackloch im ersten Festkörper befestigbaren, Befestigungsteil und mit einem radial auskragenden, in einem zeitlich später aushärtenden zweiten Festkörper fliessfähig einbettbaren, Einbettungsteil innerhalb des Einbettungsteils eine konusartig ausgeformte Konushülse auf.Essentially, a cast-in dowel with a temporary flowable hardenable fastening means can be fastened in a blind hole in the first solid, Fastening part and with a radially projecting, in a later hardening second solid body can be embedded in a fluid manner, embedding part within the embedding part a conical sleeve.
Die rotationssymmetrisch schräg zur Beanspruchungsrichtung orientierte Kegelmantelfläche der, durch die innenseitige Ausfüllung mit Beton sehr steifen, Konushülse führt bei Zugbeanspruchung des Eingussdübels zu einer für Beton günstigen Druckbeanspruchung innerhalb eines zu diesem normal orientierten Kegelmantelbereiches und somit zu einer an die Werkstoffeigenschaften von Beton angepassten Zugkrafteinleitung.The rotationally symmetrical conical surface oriented obliquely to the direction of stress which, due to the inside being very stiff with concrete, cone sleeve Tensile stress of the cast-in anchor to a compressive stress favorable for concrete within a conical surface area that is oriented towards this and thus to one the material properties of concrete adapted to the introduction of tensile force.
Vorteilhaft liegt nach Vorversuchen der axiale Halbwinkel der Konushülse im Bereich von 20° bis 40°, im simulierten Idealfall bei 30°, welcher zu einer optimalen Zugkrafteinleitung in das Material Beton führt.According to preliminary tests, the axial half angle of the conical sleeve is advantageously in the range of 20 ° up to 40 °, in the simulated ideal case at 30 °, which leads to an optimal introduction of tractive force into the Material concrete leads.
Vorteilhaft beträgt die, als das endseitige Verhältnis der Durchmesser über die axiale Länge der Konushülse bestimmte, radiale Überhöhung im Bereich von 2,5 bis 5, wodurch die axial über das Befestigungsteil des Eingussdübels eingeleitete Zugbeanspruchung vollständig in eine Druckbeanspruchung des normal orientierten Kegelmantelbereiches transformierbar ist, ohne zulässige Druckfestigkeitsgrenzen dabei lokal zu überschreiten.The end ratio of the diameters over the axial length is advantageous the conical sleeve certain radial cant in the range of 2.5 to 5, which makes the axial tensile stress introduced via the fastening part of the cast-in dowel completely in a compressive stress of the normally oriented cone area can be transformed, without locally exceeding permissible compressive strength limits.
Vorteilhaft ist die Konushülse mit im wesentlichen gleicher Wandstärke hohl ausgeformt, wodurch diese durch Stanz- und Umformprozesse in hohen Stückzahlen technologisch einfach und somit kostengünstig, weiter vorteilhaft aus Eisenblech oder Eisenrohrenden von einigen mm Wandstärke, herstellbar ist.The conical sleeve is advantageously hollow with essentially the same wall thickness, making them technologically high through stamping and forming processes simple and therefore inexpensive, further advantageous from iron sheet or iron pipe ends from a few mm wall thickness.
Vorteilhaft ist die Konushülse als separates Bauteil für die stoffschlüssige Verbindung durch Schweissen oder für die axial formschlüssige Verbindung durch Aufschrauben oder Dreheinrasten durch eine, einem speziellen restlichen Eingussdübel als zugeordnete, Schnittstelle und/oder Führung ausgebildete spezielle axiale Öffnung an der kleineren Grundfläche hergerichtet, wodurch eine der Anforderung entsprechende einfache Kombination von Systemkomponenten am Einsatzort möglich ist.The conical sleeve is advantageous as a separate component for the integral connection Welding or for the axially positive connection by screwing or Rotary snap-in by means of a special remaining cast-in dowel as assigned Interface and / or guide formed special axial opening on the smaller Base area prepared, which makes a simple corresponding to the requirement Combination of system components on site is possible.
Vorteilhaft ist die spezielle axiale Öffnung der Konushülse für die Verbindung an einem axialen Bereich des restlichen Eingussdübels ausgebildet, welcher ein axiales Überstehen des restlichen Eingussdübels über die grössere Deckfläche der Konushülse hinaus bewirkt, wodurch bei einem Einschlagen des Eingussdübels in das Sackloch die Schläge nicht unmittelbar auf die Konushülse erfolgen und diese somit vorschädigen können.The special axial opening of the conical sleeve is advantageous for the connection to one axial area of the rest of the cast-in dowel, which protrudes axially of the remaining pouring dowel beyond the larger surface area of the conical sleeve, which means that when the sprue plug is driven into the blind hole, the blows do not directly on the cone sleeve and can thus damage it beforehand.
Alternativ vorteilhaft ist die Konushülse vorgefertigt einstückig mit dem restlichen Eingussdübel ausgebildet, wodurch die Krafteinleitung begrenzende Sollbruchstellen an stoffschlüssigen oder formschlüssigen Verbindungsstellen, die am Einsatzort durch die Kombination einer separaten Konushülse mit dem restlichen Eingussdübels auftreten können, vermeidbar sind.Alternatively, the conical sleeve is prefabricated in one piece with the rest Molded dowels designed, whereby predetermined breaking points limiting the introduction of force cohesive or form-fitting connection points, which by the site Combination of a separate cone sleeve with the rest of the pouring dowel may occur can be avoided.
Vorteilhaft ist die Konushülse als radial aufgeweiteter Endabschnitt eines als Eingussdübel ausgeführten Rohrabschnitts ausgeführt, wodurch eine glatte Kraftumlenkung in der Rohrwandung ohne die Krafteinleitung begrenzende Kerben möglich ist.The conical sleeve as a radially widened end section is advantageous as a cast-in dowel executed pipe section executed, whereby a smooth force deflection in the Pipe wall without notches limiting the introduction of force is possible.
