Definitions

  • an end anchoring element for adhering fiber composite laminate strips consisting of a base plate which forms a support surface, which, viewed in the direction of the anchored end of a laminate strip in the direction of an angle W between 85 ° and 120 °, and has a curved surface for the laminate end region to be adhered, so that the one on it adhered end portion of the laminate end undergoes a bending directed against the structure B that the underside of the base plate has transverse grooves, and the clamping plate to be placed on the base plate has a curved surface matching the curved surface as the bottom, and the clamping plate at its end with a downwards directed projection the base plate at the end engages behind, as well as that the clamping and base plate are clamped together by means of screw, and at least by means of a both plates penetrating anchoring bolts in the building B are anchored.
  • the end anchoring element for fiber composite laminate strips to be adhered consists of a base plate 1 and an associated clamping plate 8 to be placed thereon, as in FIG FIG. 1 shown. These parts are made of aluminum, for example. They can be produced by injection molding, or extruded or milled from solid material.
  • the base plate 1 forms a support surface 2, which, viewed in the direction of the end of a laminate strip 3 to be anchored, encloses an angle W between 85 ° and 120 °.
  • the base plate 1 has a curved surface 4 for the laminate end region to be bonded, so that the end region 5 of the laminate end glued onto it experiences a curvature 6 directed towards the building B, that is to say the end of the lamian end is closer to the building than the beginning of the laminate end region.
  • transverse grooves 7 are formed, which are intended to receive the screw heads 15 of screws which penetrate the base plate 1 vertically upwards and protrude upwards from the base plate 1.
  • One side of the screw head 15 rests against the lateral wall 16 of the groove 7, so that the screw head 15 is secured therein against rotation.
  • the clamping plate 8 to be placed on the base plate 1 has a curved surface 9, which is suitable for the curved surface 4, as the underside 10.
  • the clamping plate 8 runs at its end in a downwardly directed projection 11, which engages behind the same at the end when placed on the base plate 1.
  • the clamping 8 and base plate 1 are clamped together by means of screw 12 and thus clamped.
  • the base plate 1 in the building B can be anchored.
  • FIG. 2 shows the end anchoring element seen from above. It is here on the top of the clamping plate 8. This is screwed by means of lock nuts 17 on the connecting screws 12 and by placing spacers 18 with the same, so that the clamping plate 8 is tightly clamped to the underlying base plate 1 and these two plates 1.8 vigorously trapped with the inclusion of the intermediate end portion of a laminate strip 3 with each other. As can be seen, the screws are arranged on both sides of the end region of the laminate strip, so that a strong tension is made possible. Because the clamping surfaces are indeed curved in one direction, the base plate 1 and the clamping plate 8 in the transverse direction are particularly stiff and the screws on the two sides of the LamiantstMails push the clamping surfaces to get rich each other.
  • the grooves 7 can be seen, which are formed in the underside of the base plate 1.
  • the screw heads 15 which abut each with one side on the groove side wall 16 so that they are secured in the grooves from twisting. Because the recess into which the base plate 1 is inserted, previously filled with an epoxy resin, the grooves 7 are filled when inserting the base plate 1 of this epoxy hard, so that an additional clawing of the base plate 1 is formed with the building.
  • the recess is first poured with epoxy resin, then the base plate 1 is inserted, so that its support surface 2 fed to the local wall of the Depression is present. Then, the base plate 1 is secured with the anchoring bolt 13. The epoxy resin is displaced and fills out the grooves 7 on the underside of the base plate 1. Then the curved upper surface of the base plate 1 is coated with epoxy resin and then the end-side portion of the laminate strip is pressed under curvature. The upper surface of the laminate strip is also coated with epoxy resin, and then the clamping plate 8 is put on and firmly clamped to the base plate 1, pinching the intermediate end portion of the laminate strip.
  • the novelty and special in the application of this Endverank fürsenses is that it allows the glued fiber composite material F additionally in the end in the support base, consisting mainly of concrete or reinforced concrete, closelybiegen.
  • the fiber composite material F which is glued to Biegezugverstärkung on the surface of the component B, preferably consists of unidirectionally arranged fiber bundles, preferably of carbon, glass or aramid fibers.
  • This fiber composite material F is glued over the entire length of the fiber composite material with the base shear resistant by means of adhesive.
  • One or both ends of the fiber composite are then glued between the lower base plate and the upper clamping plate as described.
