Definitions

  • the invention relates to a tie rod for anchoring components in a base body, e.g. Rock, brick, concrete body, among other things, in which an anchor rod is arranged within a sleeve attached to the anchoring mass on the mountain side, the sleeve having an internal thread on its inner side facing the anchor rod, the anchor rod having an external thread on its outer side facing the sleeve its mountain-side end is closed, the internal thread of the sleeve, at least at the closed end, has a larger pitch than the threads of the anchor rod and the threads of the anchor rod sit with play in the thread grooves of the sleeve.
  • Rock and earth anchors are used in tunneling, earthworks and mining and are used to hold earthworks, formwork, etc.
  • Such an anchor for anchoring components in the ground or rock has become known from DE-A-2 557 978.
  • This anchor consists of a round rod, which is provided with an external thread and forms the tension member, and which is screwed into a threaded tube which is designed as a sleeve and is to be held in the anchoring compound.
  • the pitches of the threads of the tension member and the threaded tube are the same, with lubricant being introduced in between. With this anchor, all threads are loaded evenly.
  • a disadvantage of this anchor is that it is unsuitable for high loads.
  • the invention proposes a tie rod of the type specified at the beginning, in which, according to the invention, the pitch of the internal thread of the sleeve is greatest at the closed end thereof, gradually decreases towards the open end and to half to two thirds of the length the pitch of the thread of the anchor rod is the same.
  • the sleeve including the external and internal thread, is designed as an unprocessed casting made of aluminum or gray cast iron.
  • the sleeve is preferably provided with a wedge-shaped cutting edge at its closed end.
  • the tie rod has a sleeve 1, which as a casting made of metal, preferably aluminum or gray cast iron, has a cylindrical base body 4, on the outside of which an external thread 3 and on the inside of which an internal thread 2 is provided, so that the external diameter of the internal thread «d» is smaller than the inside diameter of the external thread, and the difference between the two diameters corresponds to the actual wall thickness --a-- of the base body 4 of the sleeve 1.
  • the external thread 3 is sawtooth-shaped, so that the surface 5, which is essentially perpendicular to the axis of the sleeve, faces outwards in the installed state of the sleeve 1 and the inclined surface 6 is directed inwards, as a result of which a high resistance to tensile action in the direction of Arrow A is given.
  • the threads of the external thread 3 are close to one another, while the internal thread 2 is provided with a larger pitch, so that there is a distance -b- between the individual threads. To prevent notch stresses, the inner flank outlets of the external thread can be rounded.
  • the sleeve 1 is open at one end and closed at its other end in a wedge-shaped cutting edge 10.
  • the anchor rod 7, which is screwed into the sleeve 1, has an external thread 8 corresponding to the internal thread 2, which is designed as a so-called mammoth thread, the threads of which, as can be seen in FIG. 3, only extend over part of the surface and on run diametrically opposite points in the lateral surface, so that two axially extending, diametrically opposite, smooth lateral surfaces 9 are formed.
  • the height --H-- of the thread grooves 12 of the sleeve 1 must be greater than the height "h" of the threads 13 of the anchor rod 7, so that the threads 13 of the anchor rod 7 have a play in the thread grooves 12 of the sleeve 1 .
  • This tolerance can be a few tenths of a millimeter, e.g. 0.2 mm.
  • This tolerance preferably extends to at least half, expediently two thirds of the sleeve length and is continuously smaller and smaller, so that the slope at the closed sleeve end is greatest, and gradually decreases to the normal slope in half or two thirds of the length, so that at the end of this length there is a normal slope, that is to say the slope corresponding to the slope of the thread 8 of the anchor rod 7.
  • an adhesive cartridge is first inserted into a rock hole, whereupon the sleeve 1 is inserted into the hole and driven in by a hammer blow so that it destroys the adhesive cartridge with the cutting edge 10, as a result of which the adhesive encloses the sleeve end .
  • the adhesive is pressed progressively between the gears of the external thread 3, or driven through it, so that when the sleeve 1 is completely sunk in the rock, the adhesive all Has penetrated threads, and after hardening causes the sleeve to be firmly anchored in the rock.
  • the anchor rod 7 is screwed into the sleeve 1 fastened in this way.
  • the sleeve 1 according to the invention can be dimensioned such that it can be found with a relatively small amount of the adhesive, which is expensive per se.
  • Plastic adhesives with high strength are primarily used as adhesives. But there is also the possibility of using other masses, which give the required anchoring strength.
