Befestigungselement für den Einsatz in Mauerwerk od.dgl.Fastening element for use in masonry or the like.
Die Neuerung betrifft ein Befestigungselement für den Einsatz in Kauerwerk, Beton od.dgl., das an seinem einen vorderen Ende kegelförmig erweitert und zur Bildung einer Bohrochneide mit Abflachungen versehen ist, wobei vom anderen hiiitcren Ende des Befestigungselementes her eine Spreizhülse auf die kegelförmige Erweiterung aufschiebbar ist.The innovation concerns a fastener for the use in masonry, concrete or the like. Which widens conically at its one front end and is provided with flats to form a drill bit, the other hot end of the Fastening element ago an expansion sleeve on the conical extension can be pushed.
Mit Befestigungselementen dieser Art ist es möglich, das sie aufnehmende Bohrloch im Mauerwerk mit dem Element selbst zu bohren. Nachdem das Bohrloch auf die^e Weise gebohrt worden ist, verbleibt das Befestigungselement in dem Bohrloch und zur fertigstellung seiner Verankerung im Mauerwerk wird vom hinteren Ende des Elementes her die Spreizhülse auf die kegelförmige Erweiterung aufgepreßt.With fasteners of this type, it is possible to use the receiving hole in the masonry with the Drill element yourself. After the borehole has been drilled in this way, the fastener remains in the borehole and to complete its anchoring in the masonry is from the expansion sleeve is pressed onto the conical extension at the rear end of the element.
Das Befestigungselement ist zu seinem .vorderen Ende hin kegelförmig erweitert; in umgekehrter Richtung gesehen verjüngt es sich vom vorderen En^.e her.The fastener is at its .vorderen end widened conically; seen in the opposite direction, it tapers from the anterior end.

Jure:, die je Verjüngung wäre an sich ein Abfluß des .Sohri.iiitcrinlü möglich. Es hat eich nun aber gezeigt, daß eine Verankerung mit hohen Auszugs-icrüf ten dann erreicht; werden kann, wenn die kegelförmige Erweiterung oder, in umgekehrter iiichtung gesellen, Verjüngung einen verhältnismäßig kleinen V.'ert aufweist. Es entsteht nämlich dabei ein hohes I'aß an Selbsthemmung und die Hülse kann in ihrer Wandstarke verhältnismäßig dünn gehalten werden, was ihr Aufspreisvermögen erleichtert. Jurch das verhältnismäßig geringe Maß der Erweiterung kommt es nun aber vor, daß das Bohrmaterial-nicht menr ohne weiteres abgeführt werden kann. Insbesondere wenn bei;.: Bohren harte, größere ü-es te inspar ti..-:el gebrochen werden, besteht die (J-efahr, daß diese nici.t abgeführt werden und sich zwischen Befestigungselement und Bohrlochwandung festsetzen. Jie^ kann unter Umstanden dazu führen, daß ein Aufpressen der Spreizhülse unmöglich wird.Jure: that ever rejuvenation would in itself be a drain of the .Sohri.iiitcrinlü possible. But it has now shown that an anchoring with high pull-out I then checked achieved; can be if the conical extension or, in the opposite direction, companions, Taper has a relatively small V.'ert. This creates a high level of noise Self-locking and the sleeve can be kept relatively thin in its wall thickness, what facilitates their upside potential. Jurch that proportionally low degree of enlargement occurs but now before that the drilling material -not without further can be discharged. Especially when;.: Drilling hard, larger ü-es te inspar ti ..-: el broken there is a risk that this will not are dissipated and located between the fastener and fix the borehole wall. Jie ^ can under certain circumstances lead to pressing the expansion sleeve becomes impossible.
Der feuerung liegt die Aufgabe zugrunde, das Befestigungselement so zu verbessern, daß die geschilderten Nachteile nicht mehr auftreten.The firing is based on the task of the fastener to improve so that the disadvantages described no longer occur.
Neuerungsgemäß wird dies dadurch erreicht, daß das Befestigungselement mit.von den Abflachungen ausgehenden, sich schrauben'linienförmig um das Element zu seinem hinteren Ende hin windenden Nuten versehen ist.According to the innovation, this is achieved in that the fastening element with. helically around the element is provided at its rear end winding grooves.

jjiese L'uten gewährleisten nun in jedem i'vall das Abführen dea Bohrmaterials auch dann, wenn größere U-estein^partikel anfallen. Zwar erfährt uas Befestigungselement durch die Muten eine Schwächung des o.uerachnitts und damit eine Schwächung der festigkeit. Es hat sich jedoch überraschenderweise gezeigt, daß die festigkeit des Elementes selbst mit Nuten so hoch oder höher liegt, als die Aus- Ijjiese L'utes now extends to all i 'v all the discharge dea drilling material even if larger U-Estein ^ particles are incurred. It is true that the fastening element experiences a weakening of the o.uerachnitts and thus a weakening of the strength due to the grooves. However, it has surprisingly been shown that the strength of the element, even with grooves, is as high or higher than the design
zugsfestigkeit des verankerten Elementes.tensile strength of the anchored element.
.'las in der Zeichnung als Ausführungsbeispiel der Neuerung dargestellte Befestigungselement 1 ist an seinem einen vorueren Ende 2 kegelförmig erweitert. Zur Bildung der Pohrschneide 3 sind an diesem Ende zwei einander gegenüberliegende Abflachungen 4 angeordnet, die sich zum Ende 2 hin einander nähern. Der Schaft 5 des Befestigungselementes i ist mit einem Gewinde 6 versehen. Am anderen, hinteren . nde 7 ist ein Ansatz 8 vorgesehen, der zur Aufnahme äes Elementes in einem nicht dargestellten Bohrmaschinenfutter geeignet ist. Jer Ansatz ist durch die Quersc nittsverringerung 9 nach dem Erstellen des Bohrloches abbrechbar. Von den Abflachungen 4 gehen sich schraubenlinienförmig zum hinteren Ende 7 hin windende fluten 10 aus, die zur Abfuhr des beim Bohren anfallenden Bohrmaterials dienen. Nach dem Erstellen des Bohrloches ist vom hinteren Ende 7 her eine (nicht dargestellte) Spreizhülse über den Schaft auf das kegelförmig erweiterte vordere Ende 2 aufpreßbar. .'las in the drawing as an embodiment of Fastening element 1 shown here is widened conically at its one front end 2. To form the Pohr cutting edge 3, there are two opposite flats at this end 4 arranged, which approach each other towards the end 2. The shaft 5 of the fastening element i is provided with a thread 6. At the other, rear. nde 7, a projection 8 is provided, which is used to accommodate aees element in one drill chuck not shown is suitable. The approach is through the cross-section reduction 9 can be broken off after the drill hole has been created. From the flats 4 go helically towards the rear end 7 winding floods 10, which are used to remove the accumulating during drilling Serve drilling material. After creating the borehole from the rear end 7 is a Expanding sleeve (not shown) can be pressed onto the conically widened front end 2 via the shaft.
