  • this object is achieved in that the respective first plate, the regions of the bracket elements attached to the first plate and the regions of the mandrel or sleeve which are adjacent to the respective plate are embedded in a plate-shaped element is formed from a high-strength mortar-like mass, which surrounds the first plate on all sides.
  • this plate-shaped element made of a high-strength mortar-like mass it is achieved that the joint area of the components to be connected is massively reinforced at the respective point where the connecting elements mandrel and sleeve are inserted. Since the first plates are enclosed on all sides by the mortar-like mass of the plate-shaped element, this first plate can be made from an inexpensive material; it does not have to be corrosion-resistant since it is completely sealed off. The forces to be absorbed by the respective mandrel and the sleeve are optimally determined by the respective first Transfer plate and the bracket elements to the plate-shaped element and introduced into the surrounding concrete of the respective components.
  • the mortar-like mass of the respective plate-shaped element is advantageously an ultra-high-performance fiber-reinforced concrete, as a result of which the strength of this plate-shaped element can be increased still further.
  • At least part of the side surfaces of the plate-shaped element is provided with projections and depressions, as a result of which it can be achieved that the anchoring in the concrete of the components is additionally improved.
  • the projections and depressions are designed as ribs and grooves, by means of which the transfer of the transverse forces from the mandrel and sleeve to the components and vice versa is additionally improved, the surface areas which absorb the forces are enlarged.
  • a further advantageous embodiment of the invention consists in that the bracket elements comprise further plates, and the end regions of the bracket elements facing away from the first plate are provided with bends. This ensures that the bracket areas are optimally anchored in the components.
  • the end regions of the bends lying opposite one another advantageously abut one another and are connected to one another and enclose the mandrel or the sleeve.
  • the anchoring of the mandrel and the sleeve in the respective components is improved by the closed loop of the first plate with the further plates and the enclosing of the mandrel or the sleeve.
  • bracket elements further comprise rod-shaped anchoring irons which are fastened to the first plate and / or to the further plates, what else is optimized if the rod-shaped anchoring irons are bent over in such a way that they form a ring.
  • FIG. 1 the sleeve 1 of the inventive device for connecting two components separated by a joint can be seen.
  • this sleeve 1 is equipped with reinforcing elements 2, the area of the sleeve 1 directed against the joint is provided with a plate-shaped element 3, which is completely penetrated by the sleeve 1, so that, as will be seen later is, the entrance to the sleeve 1 is free and the mandrel can be inserted into the sleeve 1.
  • This plate-shaped element 3 consists of a high-strength mortar-like mass, which can be, for example, an ultra-high-performance fiber-reinforced concrete.
  • the plate-shaped element 3 is rectangular, of course other shapes would also be conceivable, for example round, the two opposite side surfaces 4 are provided with projections 5 and depressions 6.
  • these projections 5 and depressions 6 can be applied distributed over all the surfaces forming the periphery of the plate-shaped element 3 or only on a part thereof.
  • These projections 5 and depressions 6 are designed as ribs 7 and grooves 8, which are aligned essentially parallel to the sleeve 1 in the embodiment shown here.
  • the projections 5 and depressions 6 can be designed as pins, the depressions could also have the shape of a pin.
  • the sleeve 1 can be seen, to which the reinforcing elements 2 are attached.
  • These reinforcing elements 2 have a first plate 9 directed against the joint, which is oriented essentially perpendicular to the sleeve 1 and which has an opening 10 through which the sleeve 1 is guided.
  • the first plate 9 and the sleeve 1, which are formed, for example, from a metallic material, are firmly connected to one another, for example by welding.
  • bracket elements 11 on opposite sides attached, which extend away from the joint.
  • These bracket elements 11 consist of two further plates 12, these further plates 12 and the first plate 9 can, for example, be made in one piece, the further plates 12 can be bent at right angles to the first plate 9.
  • the end regions of the further plate 12 facing away from the first plate 9 are provided with bends 13.
  • the end regions of the bends 13 lying opposite one another can abut one another and be connected to one another, for example by welding.

  • the length of the plate-shaped element 3 can then be, for example, approximately 135 millimeters, while the width is 110 millimeters.
  • these measurements can be adapted to the respective conditions. If thicker sleeves are used, the dimensions given above can be adjusted, for example, in proportion to the sleeve diameter.
  • the thickness of the overlap of the first plate 9 against the joint can be, for example, only about 10 millimeters in order to protect the first plate against corrosion. With normal concrete, from which the components to be connected are made, this dimension would have to be chosen much larger in order to be able to achieve complete corrosion protection.
