  • the mandrel part is arranged in a first component so that the one end region of the mandrel protrudes from the relevant component, this protruding end portion of the mandrel penetrates into a sleeve which is arranged in the other component.
  • the mandrel is held longitudinally displaceable in the sleeve, whereby the expansions of the components can be compensated.
  • the sleeve can also be designed in a known manner so that even small lateral displacements of the mandrel are made possible in the sleeve.
  • the object of the present invention is therefore to provide a device for connecting two components separated by a joint, in which the material costs can be kept as low as possible, and which optimal support in the corresponding components and optimal power transmission to the corresponding components and vice versa.
  • the solution of this object is achieved in that at least the two side surfaces of the filling material, which are bounded by the first plate and the strap portions are provided with projections and depressions, which are molded into the filling compound and that the filling compound (7) is a high-strength mortar-like Mass is.
  • the first plate may have a smaller thickness, accordingly, the ironing regions may have a smaller thickness, whereby material can be saved and the material costs can be reduced.
  • the filling material is a high-strength mortar-like mass
  • the desired strength can be achieved
  • this mortar-like mass can be poured into correspondingly applied around the mandrel or the sleeve shapes and then cure.
  • the side surfaces of the filling compound on a concave curvature ensures that the anchoring in the material of the components is additionally improved by the concave curvatures obtained in addition a positive connection of the reinforcing elements with the components.
  • the projections and recesses are formed as ribs and grooves which extend substantially parallel to the strap portions.

  • the ribs and grooves have a triangular cross-section, the transmission of forces is thereby optimal.
  • a further advantageous embodiment of the invention is that the apex angle of the triangular cross-sections of the ribs and grooves is about 60 ° to 120 °.
  • the force-receiving surfaces of the ribs and grooves will have an optimal inclination to absorb the lateral forces as well as possible.
  • the vertex angle of the triangular cross-sections of the ribs and grooves of a side surface is different in size, whereby also transverse forces, which may have different directions, can be optimally absorbed.
  • the first plate facing away from the end portions of the strap portions are provided with bends, whereby an optimum connection between the plate and strap portions and the enclosed filling material is achieved.
  • a further advantageous embodiment of the invention is that the rear surface formed by the filler between the two bends is also provided with projections and depressions and the rear surface also has a concave curvature. As a result, the anchoring of the reinforcing element in the component is additionally improved.
  • a further advantageous embodiment of the invention is that the end portions of the opposing bends abut each other and are connected to each other and enclose the mandrel or the sleeve. This ensures that the filling material is optimally enclosed.
  • the end portions of the opposing bends may also overlap each other and be provided with openings through which the mandrel or the sleeve protrude, thereby it is not necessary to additionally connect the bends with each other.
  • clamping bolts are used in the ironing areas, which penetrate the two ironing areas and the filling compound and thus gain can be achieved.
  • a first embodiment is shown, each consisting of a mandrel 1 and a sleeve 2.
  • a reinforcing element 3 is mounted in each case.
  • Each of these reinforcing elements comprises a first plate 4, which is aligned perpendicular to the mandrel or sleeve 2 respectively.
  • bracket portions 5 are mounted, which are equipped at the end of the respective first plate 4 end portions with bends 6.
  • the space formed between the stirrup areas 5 and the bends 6 is filled by a filling compound 7.
  • This filler may be a high-strength mortar, but of course other suitable materials are used.
  • a mold can be made in a known manner, by which said space is enclosed, so that the flowable filling compound 7 can be poured into this mold. After curing of this filling compound 7, the mold can be removed, the filling compound 7 then forms a body which fills said space and the mandrel 1 and the sleeve 2 encloses accordingly.
  • the side surfaces 8 of the body formed by this filling compound 7 have a concave curvature 9.
