Definitions

  • the invention is based on a force introduction element for Anchoring a band-shaped composite material to a support structure according to the preamble of the first claim.
  • the invention also relates to a method for increasing the tensile load a band-shaped composite material and the use of a Force introduction element for reinforcing a support structure.
  • the solution to the problem is that after the clamping process of the band-shaped composite material in the pulling direction in a second step a means for preventing additional stress build-up at Transition from the cross-traverse to the force introduction element is used.
  • the composite is over the The force application element and the transverse crosshead are tensioned onto the preload load. This creates voltage spikes at the transition of the cross-beam to Force application element.
  • After preloading and anchoring on Bauwerk will use a compound with the composite material in a stretched state an adhesive or mechanically bonded.
  • the connection between the Means and the composite material is free of tension at this time.
  • at an additional load of the composite e.g. from operating loads, become the resulting additional stresses mainly on the upstream means directly into a supporting structure and not or only slightly in the Transmitted force introduction element. This results in an increase in the Total load while maintaining the required safety factor.
  • the force introduction element may be referred to as a clamping head be and can be configured essentially as desired.
  • this force introduction element of two pressure plates and at least one tension member passed through the composite, e.g. Bolt.
  • the composite material is using two pressure plates with the help of uniformly distributed printing elements or by means of one on the entire Anpress Design acting hydraulic pressure chamber against a bow-shaped yoke held supported.
  • clamping wedges instead of bolts and plates are used clamping wedges, the elliptical ring hoop to the Composite material to be pressed.
  • the inventive solution used for each existing on the market force application element can be.
  • This means of reducing stress peaks at the transition from the cross-beam to the force introduction element can Extension element to the composite material and tensile to the Transverse cross member mechanically anchored and / or glued.
  • the cross-beam is in the second step by injecting an adhesive connected to the composite material. Increased by this tensioning process the maximum transferable operating forces in compliance with a Safety factor of 1.5 at least 20-50% in a range of 300 up to 400 kN.
  • FIG. 1 and 1a is a force introduction element 1 after a Clamping process shown.
  • the clamping process can first with a pull press take place, which is temporarily arranged on the force introduction element 1.
  • Threaded rods 9 are laterally on the force introduction element. 1 mounted, these threaded rods 9 through the cross-beam 2 of the Force introduction element 1 lead.
  • the force application element 1 is about the cross-beam 2 and the threaded rod 9 in a not shown Anchoring tube or shear pin held in a well in a Support structure 10 is attached.
  • a threaded screw 8 of Threaded rod 9 the tension of the composite material 5 can be increased.
  • Adhesive 6 becomes after the clamping process of the force introduction element 1 in the pulling direction 11 in a second step on and in front of the transverse cross member 2 opposite the force introduction element 1 on the band-shaped Composite 5 applied.
  • the adhesive is especially pasty to the To facilitate processing.
  • An extension element 4 is placed on the on the band-shaped composite material 5 lying adhesive compound 6 launched and on glued the cross-Traverse 2 of the force application element 1 and preferably mechanically by lateral sliding of the Extension element 4 anchored in the cross-beam 2. For this purpose, the Cross-traverse clamp-like extensions on.
  • the extension element 4 must be resistant to tension with the transverse crossbeam. 2 be connected.
  • the shape of the extension element 4 depends on the Choice of material of the extension element 4 and the thickness of Composite 5 and is chosen, inter alia, that the Extension element 4 to the composite material 5 back from the cross-beam Tapered away.
  • the extension element 4 can take any shape, but preferably have a tongue or wedge-shaped configuration to optimally reduce the voltage peaks. Also, in the Extension element 4 in the pulling direction 11 a few centimeters long ribs and folds 13 are introduced to allow for optimal bonding and to ensure optimum stress relief.
  • the extension element 4 preferably has a length, respectively on the top and bottom of the band-shaped composite material 5, of 100 mm, in particular 50 mm. In the center of the extension element, this preferably has a thickness of a maximum of 10 mm, in particular a maximum of 5 mm.
  • the Extension element 4 and the cross-beam 2 is preferably made metallic, ductile materials, in particular of aluminum, steel or Titanium.
  • the adhesive 6, e.g. a 2K adhesive based on epoxy resins, must a good adhesion not only to the composite material 5, but also to the Extension element 4 have and should have a high strength.
  • the transferable force increases in compliance with the Fuse factor of 1.5 up to 20 - 50% compared to one Force introduction element 1, in which a cross-Traverse 2 frontally arranged the pressure plates 3 and no extension element 4 is used becomes.
  • the available tensile load of the composite material 5 can be utilized to a greater extent and an expected tensile force of 300 to 400 kN can be achieved.
  • the composite material 5 can be configured in the form of a lamella, which consists of fibers and a synthetic resin.
  • the fiber can be in one Direction i. be formed unidirectionally or additionally fibers in others Directions, in particular an angle plus 45 ° and minus 45 °, to be constructed unidirectional main fiber direction.
  • the fibers can preferably of aramid, carbon, glass, etc., which are in a synthetic resin are embedded.
  • the synthetic resin may be a duromer such as e.g. Epoxy, acrylates or a thermoplastic material, such as e.g. Polyamide, epoxy, acrylates.
  • a duromer such as e.g. Epoxy, acrylates or a thermoplastic material, such as e.g. Polyamide, epoxy, acrylates.
  • Figure 1 b shows the force introduction system 1, in which before the Clamping process a bond 6 between the cross-beam 2 and the Composite material 5 executed and after the clamping process the Extension element 4 is attached. This results in the area of the cross-beam 2 shows a different voltage curve 12 than that in FIG. 1 shown so that the highest voltage peaks already in the range of Cross traverse occur.
  • Figures 2 and 2a show that after the clamping process of a Force introduction element 1 in the pulling direction 11 in a second step the Cross-Traverse 2 by injecting an adhesive 6 with the Composite 5 is connected. Since the cross-Traverse 2 in a second Step is glued to the composite material 5, the voltage spikes both at the location of the cross-beam 2 and the composite material 5 as well as on Location of the transverse cross member 2 and the force application element 1 highest and decrease in the pulling direction 11.
  • extension element 4 lying on the adhesive compound 6 on the band-shaped composite material 5 placed and glued to the cross-beam 2 of the force application element 1 and fixed with at least one screw 7. This points to that Extension element 4 an extension with holes through which the Guided screws and can be connected to the cross-beam.
  • 4a, 4b and 4c is the extension element 4 on the lower side to the composite material. 5 specially shaped to a good bond and thus a high To ensure tension in the pulling direction 11.
  • the Extension element 4 is also here on the adhesive 6, which on the band-shaped composite material 5 was applied, laid on and also adhered to the cross-beam 2 of the force introduction element 1.
