Definitions

  • the invention relates to an injection packer of the type specified in the preamble of the main claim.
  • mineral binders are used instead of synthetic resin. Because of the different composition and flow properties of synthetic resins and mineral binders, the injection packers used for synthetic resins are not suitable for pressing mineral binders.
  • the invention has for its object to provide an injection packer that is suitable for the compression of mineral binders and is both inexpensive to manufacture and easy and quick to assemble.
  • connection Due to the connection molded integrally on the shaft in the injection molding process, it is possible to provide the longitudinal bore through the connection and shaft with a diameter that is the same over the entire length. This ensures an undisturbed, trouble-free flow. Furthermore, sealing problems between the connecting piece and the shaft are avoided.
  • the injection packer consists of only one part and is thus very inexpensive to manufacture. For assembly, the injection packer is inserted into the prepared borehole, the diameter of which is slightly larger than the smallest diameter of the conical shaft. The injection packer is driven into the borehole with several hammer blows until the stem of the injection packer is firmly wedged in the borehole with a tubular impact tool that can be placed over the connection and is seated on the stop shoulder formed by the larger shaft diameter.
  • the binder After connecting the hose of the high-pressure pump, the binder is now injected into the blind hole until material rises from the injection packers placed next to it.
  • the outer surface of the shaft can be provided with circumferential ribs, which can also be designed as a thread with a sawtooth profile.
  • the injection packers 1a, 1b according to FIGS. 1 and 2 are made of impact-resistant plastic by injection molding, the connection 2 being integrally formed on the shaft 3.
  • the shaft 3 is conical in both embodiments, the shaft 3 of the injection packer 1a having a smooth outer surface 4. Due to the reduced diameter of the connection 2 compared to the shaft diameter, a stop shoulder 5 results, on which the insertion tool 6, which can be put over the connection 2, can be placed. With this impact tool 6, the injection packer 1a is driven into a blind hole 7 until the shaft 3 of the injection packer is wedged in the hole 7.
  • the mineral binder After postponing the with an ent speaking coupling piece provided hose (not shown) on the connection 2 of the injection packer, the mineral binder is pressed with a high pressure pump through the longitudinal bore 8 of the injection packer 1a, 1b into the blind hole. Due to the high pressure of approx. 200 bar, the binder penetrates through the wall of the blind hole into the material of the component to compress it. The injection is carried out until material rises from the adjacent injection packer.
  • the shaft 3 of the injection packer 1b according to FIG. 2 has, on its outer surface, circumferential ribs 9 designed as threads. It is advisable to use a rotary impact wrench to set such an injection packer.
  • the latter For torque transmission from the machine to the injection packer, the latter has a square 10 at the end of the shaft 3 having the connection 2, by means of which a key clamped in the machine can be put over.
