Definitions

  • the invention relates to a device for partial Filling a borehole with adhesive, with a cartridge and a spout attached to this for insertion into the borehole and for spraying out the adhesive.
  • the borehole is partially covered with an adhesive filled.
  • the anchor bolt is then under formation of a Annular gap inserted into the borehole, the anchor bolt the adhesive present in the borehole in the annular gap presses.
  • the one in the borehole fills Adhesive exactly the annular gap between anchor bolt and Borehole wall out, so that neither excess adhesive part of the annular gap emerges from the borehole is not filled with adhesive.
  • the excess adhesive unnecessary cost and additional Effort of work because overflowing adhesive is removed must become; in the second case is due to the lack of gluing resilience in the non-filled annular gap section of the anchor bolt impaired.
  • Such - often not noticed - underdosing of the adhesive has on the Safety of anchor bolt attachment negative effects.
  • An associated drill hole length can be specified for each anchor bolt diameter and an associated borehole diameter is specified become.
  • the present invention has the object based on a very precisely metered introduction with little effort of adhesive in a borehole.
  • this object is achieved in a device type mentioned solved in that the ejection nozzle with its free end to essentially the end of Borehole in this is insertable that in the area of free end of the ejection nozzle relative to this immovable an essentially radially extending the free end enclosing sealing lip is attached, the the gap when inserted into the borehole between the outside of the ejection nozzle and the borehole wall seals, so that in the introduced adhesive existing pressure the ejection nozzle with the sealing lip moves towards the mouth of the borehole, and that at the ejection nozzle at least a predetermined distance from the Sealing lip a mark is arranged in the course the movement of the ejection nozzle by stepping out is visible from the borehole.
  • the measures according to the invention can be carried out in one Adhesive to be drilled into the drill hole easily and precisely be dosed.
  • a radially extending Sealing lip or a sealing ring is attached, which or the the space between the outside of the ejection spout and seals the borehole wall is in the borehole a kind of dosing piston formed, which prevents adhesive on the side of the sealing lip facing the cartridge flows.
  • This sealing causes that in the Space between the borehole end and the sealing lip Adhesive the ejection nozzle with the sealing lip in like a piston pushed towards the mouth of the borehole becomes.
  • the ejection nozzle Even if the borehole is facing down, the ejection nozzle with the pressure of the adhesive the sealing lip together with the cartridge. It is not necessary to pull the device upwards.
  • the distance traveled or the route by which the Ejection nozzle is pushed out of the borehole is a measure for the amount of adhesive injected.
  • One at the Ejection nozzle attached mark that depends in one from the borehole depth and the borehole diameter or the Anchor bolt diameter suitably chosen, given distance is arranged by the sealing lip, emerges from the borehole out and becomes visible when the desired one Amount of adhesive is introduced into the borehole.
  • the size of the distance between the marking and the sealing lip corresponds thus the borehole length section that is free of adhesive should stay.
  • the concept according to the invention ensures precise filling a predetermined amount of adhesive into the borehole possible. According to the invention, smaller deviations are also possible with the borehole diameter when measuring the adhesive with taken into account because of a hole with a larger diameter more mass is introduced until the mark is reached must be than with a borehole with a smaller diameter.
  • the invention also ensures that do not form air bubbles in the borehole as the adhesive is continuous from the bottom of the borehole to the desired depth is applied. In a device according to the invention is further through the sealing lip, the adhesive from the outside Keep the ejection nozzle away so that it is clean remains and corresponding cleaning work is omitted.
  • Ejection spout in two parts from one attached to the cartridge Part and a detachable, located at the free end formed the part having the sealing lip.
  • this two-part design can be the lower, the sealing lip having part independent of the upper part of the ejection nozzle be replaced.
  • This has the advantage that only this part to the individual dimensions of the mounting bolt needs to be adapted. It offers itself to this part adapted to the dimensions of the bolt to be delivered together with the bolt to be anchored.
  • the upper part of the ejection nozzle needs - except for a fastening option for the lower part - not special to be adapted to the system according to the invention.
  • Another Advantage of the two-part training is that time-consuming cleaning work can be omitted after use, since only the part of the ejection nozzle that can be produced cost-effectively wetted outside by the adhesive when used and this part can be disposed of after use.
  • the two parts are preferably connected by means of a clip-like connection, e.g. at the top of the Ejection spout a circumferential bead is provided, which in engages a corresponding groove in the lower part and the two parts locked against each other.
  • the holding force is like this to choose that the connection of both parts when pulling out the ejection spout from the borehole is not inadvertently solves.
  • the marking is in the two-part embodiment of the Ejection nozzle preferred by the transition between the formed both parts.
  • Adhesive volume exactly depending on the bolt to be used be specified.
  • a kind of scale would be on the ejection nozzle with markings for different borehole diameters conceivable.
  • the downhole parts of the ejection nozzle are preferably dependent on the respective borehole diameter trained in different colored plastics, whereby handling is made easier.
  • the color of the plastic the lower part is preferably in contrast to the color of the Material of the upper part of the ejection nozzle, so that the mark formed by the transition between the parts is clearly visible.
  • the sealing lip is particularly useful as a circumferential, radially extending plastic film to the same from the same Plastic-made lower part of the connector molded and integrally formed with this.
  • the sealing lip can also be detachably attached to the ejection nozzle be attached.
  • different Hole diameters only the sealing lip be replaced at the ejection nozzle.
  • the sealing lip in the radial direction has a predetermined excess. With this measure you can Unevenness in the borehole wall is compensated, to prevent adhesive from breaking out or out of round Drilled holes are pressed past the sealing lip.
  • the sealing lip is preferably formed from polyethylene. This Material ensures when absorbing the adhesive pressure sufficient strength a sufficient elastic Deformability to conform to the borehole wall.
  • the single figure shows a device according to the invention as well as their use for fastening an anchor bolt.
  • the illustrated embodiment of an inventive The device has a cartridge 1 and a cylindrical one two-part ejection nozzle 10, one part 2 on the Cartridge 1 is attached, for example by means of a Screw connection 4, and the other part 12 in a borehole 6 is inserted in a component 7.
  • the cartridge 1 can be used as adhesive 8 e.g. Two-component mass with microencapsulated Peroxide included.
  • Length and diameter of the entire spout 10, the also referred to as a mixer, are chosen so that they can be introduced to the end of the borehole 6.
  • the diameter of the ejection nozzle 10 can be 8 mm, for example are M8 for drill holes for anchor or threaded bolts, M10, M12 and M16.
  • End 5 of the lower part 12 of the ejection nozzle 10 is one injected annular sealing lip 9, the free end 5 encloses and the space between the outside the ejection nozzle 10 and the borehole wall seals to a Prevent the passage of adhesive 8 there.
  • the two Parts 2, 12 of the ejection nozzle 10 are by a plug connection 17 connected together so that the lower part 12 by changing to the desired borehole diameter can be adjusted. This way too the radial extension of the sealing lip 9 to different Adjusted borehole diameter.
  • the sealing lip 9 is elastic and trained in excess so that they can easily can adapt to any unevenness in the borehole wall. As Material for the sealing lip 9 can e.g. Polyethylene chosen become.
  • the sealing lip can be injection molded directly foil-like on the lower part 12 of the ejection nozzle 10 are molded.
  • a mark 12a is formed.
  • the distance between the sealing lip and this marking depending on the borehole diameter for threaded bolts (e.g. M8, M10, M12 and M16) selected.
  • threaded bolts e.g. M8, M10, M12 and M16
  • the filled one Adhesive 8 just for filling the annular gap 14 between Bolt outside and borehole wall.
  • Threaded bolt 13 a hole 6 with the depth and the diameter drilled for the diameter of the to be fastened Threaded bolt 13 are predetermined, so for example for a M16 threaded bolt, a 125 mm hole Depth and 18 mm diameter. Then 1 the upper part 2 of the ejection nozzle 10 attached. On the Free end 5 of the ejection nozzle 10 is now for one M16 threaded bolt or for a borehole diameter of 18 mm fitting part 12 with corresponding sealing lip 9 placed and the ejection nozzle to the end of borehole 6 used in this.
  • the sealing lip 9 is now on the one hand on the outside of the ejection nozzle part 2 and on the other hand on the borehole wall and seals the space between End of the borehole and end 5 of the ejection nozzle 10.
  • adhesive 8 through the spout 10 introduced into the borehole 6.
  • Adhesive 8 By the pressure of the introduced Adhesive 8 is the ejection nozzle 10 together moved or pressed with its seal 9 towards the mouth of the borehole, the space between the end of the borehole and the end of the Ejection nozzle is completely filled with adhesive 8. If the marking 12a emerges from the borehole 6, the supply of further Adhesive 8 ended because now the prescribed Amount of adhesive 8 is present in the borehole 6.
