Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruches 1, insbesondere den Merkmalen des Kennzeichenteils, wonach das Bohrkronenrohr ein innen angeordnetes Schutzrohr aufweist und dass in einem Ringraum zwischen Schutzrohr und einem Rohrmantel des Bohrkronenrohres eine schalldämmende Schicht angeordnet ist, die beim Bohren in den Freischnitt gleitet.The solution This object is apparent from the features of claim 1, in particular the Characteristics of the characteristic part, according to which the drill bit tube an inside arranged protective tube and that in an annular space between the protective tube and a pipe jacket of the drill bit pipe a sound insulating layer is arranged, which slides when drilling in the cut-out.

Das erfindungsgemäße Bohrkronenrohr hat den wesentlichen Vorteil, dass durch das innen angeordnete Schutzrohr sowie die in dem Ringraum zwischen Schutzrohr und Bohrkronenrohr angeordnete schalldämmende Schicht die Lärmbelästigung beim Bohren verringert wird, da Vibrationen und Schleifgeräusche des Bohrkernes am Bohrkronenrohr deutlich gedämpft werden. Während des Rohrens taucht nämlich das innen angeordnete Schutzrohr nebst der im Ringraum angeordneten schalldämmenden Schicht automatisch in den durch die Schneidmittel erzeugten Freischnitt ein, so dass eine weitgehende Schallentkopplung zwischen dem Bohrkern und dem sich drehenden Bohrkronenrohr stattfindet.The The drill bit tube according to the invention has the significant advantage that through the internally arranged protective tube as well as in the annulus between the protective tube and drill bit tube arranged sound-insulating Layer the noise pollution is reduced during drilling, since vibrations and grinding noises of the Drill core are significantly attenuated at the drill bit tube. During the Rohrens dives the internally arranged protective tube together with the arranged in the annulus sound insulating layer automatically in the free cut produced by the cutting means a, so that a substantial sound decoupling between the core and the rotating drill pipe takes place.

Auf vorteilhafte Weise kann die schalldämmende Schicht aus Kunstharz oder aus Bauschaum gebildet werden, die nach der Erstellung des Bohrkronenrohr in den Ringraum jeweils eingebracht wird.On Advantageously, the sound-absorbing layer of synthetic resin or made of construction foam, which after the creation of the Bohrkronenrohr is introduced into the annulus respectively.

Letztlich ist bei einer bevorzugten Ausführungsform der Erfindung das Schutzrohr mit dem Deckel schweißverbunden.Ultimately is in a preferred embodiment the invention, the protective tube welded to the lid.

Weitere Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispieles. Es zeigen:Further Advantages of the invention will become apparent from the following description an embodiment. Show it:

2 eine vergrößerte Darstellung eines Bohrkronenrohres und 2 an enlarged view of a Bohrkronenrohres and

3 eine vergrößerte Teildarstellung des in den Freischnitt eintauchenden Bohrkronenrohres. 3 an enlarged partial view of the dipping into the cut-free drill bit tube.

In den Zeichnungen ist ein Bohrkronenrohr insgesamt mit der Bezugsziffer 10 bezeichnet.In the drawings, a drill bit tube is indicated generally by the reference numeral 10 designated.

In der 1 erkennt man ein auf einem Deckenbereich 11 eines Gebäudes stehendes Bohrgerät 12 in schematischer Darstellung. Das Bohrgerät weist einen Standfuß 13 auf, an dem eine Halterung 14 zur höhenverstellbaren Befestigung des motorischen Antriebes 15, eine hohle Antriebswelle 16, eine Einrichtung zur Verbindung des Bohrkronenrohres 10 mit der Hohlwelle 16 eines motorischen Antriebes 15 sowie das Bohrkronenrohr 10 angeordnet sind. Deckenseitig weist das Bohrkronenrohr 10 Schneidmittel 18 auf, mit denen beispielsweise die dargestellte Decke 11 eines Gebäudes durchbohrt werden kann. Die Schneidmittel 18 können aus Diamant oder beispielsweise auch aus Hartmetall gebildet werden.In the 1 one recognizes one on a ceiling area 11 a building standing drill 12 in a schematic representation. The drill has a pedestal 13 on to which a bracket 14 for height-adjustable attachment of the motor drive 15 , a hollow drive shaft 16 , means for connecting the drill bit tube 10 with the hollow shaft 16 a motor drive 15 as well as the drill bit tube 10 are arranged. Ceiling side, the drill bit tube 10 cutting means 18 on, with which, for example, the illustrated ceiling 11 of a building can be pierced. The cutting means 18 can be formed of diamond or for example also of hard metal.

In der 2 ist darüber hinaus in vergrößerter Darstellung das Bohrkronenrohr 10 zu erkennen. Dargestellt ist zum einen eine Einrichtung 17 zur Verbindung des Bohrkronenrohres 10 mit der nicht dargestellten Hohlwelle 16 eines motorischen Antriebes 15, welche aus einem Anschlussflansch 19 und einem Deckel 20 gebildet wird.In the 2 is also an enlarged view of the drill bit tube 10 to recognize. Shown is on the one hand a device 17 for connecting the drill bit tube 10 with the hollow shaft, not shown 16 a motor drive 15 , which consists of a connection flange 19 and a lid 20 is formed.

Darüber hinaus ist zu erkennen, dass das Bohrkronenrohr 10 innen ein Schutzrohr 21 aufweist, welches fest mit dem Deckel 20 vorzugsweise schweißverbunden ist. Ein Ringraum 23 zwischen einem Rohrmantel 24 des Bohrkronenrohres 10 und dem Schutzrohr 21 ist mit einem schalldämmenden Material 22 gefüllt. Dabei kann es sich beispielsweise um Kunstharz oder Bauschaum handeln.In addition, it can be seen that the drill bit tube 10 inside a protective tube 21 which is fixed to the lid 20 preferably connected by welding. An annulus 23 between a pipe jacket 24 of the drill bit tube 10 and the protective tube 21 is with a sound absorbing material 22 filled.
