Definitions

  • the invention relates to a flat strip lamella for reinforcement of load-bearing or load-transmitting Components that consist of a composite structure from a Variety of flexible bends aligned parallel to each other or limp supporting fibers and one the supporting fibers shear-resistant binding matrix exists and the broadside by means of an adhesive attachable to the surface of the component to be reinforced is.
  • the invention further relates to a method to attach such flat ribbon slats one component.
  • Reinforcement slats of this type are known, for example from WO 96/21785.
  • the reinforcement slats are there on elongated and / or flat components used.
  • the one binder matrix from one Thermoset, especially made of epoxy resin Reinforcement slats do not allow bends with small ones Bending radii so that over a component edge guided, bow-like reinforcements are not possible with this were.
  • bow-shaped reinforcements needed for reinforced concrete beams and reinforced concrete slab beams the relationship between the printing and Secure the tensile zone and avoid shear and transverse cracks.
  • the invention is based on the object to develop a flat ribbon slat, the one cross-edge reinforcement of components.
  • Another object of the invention is the development of a method for applying such Ribbon slats on components.
  • the bending stiffness of the flat strip slats mainly caused by the binder matrix.
  • the binder matrix consists of a thermoplastic.
  • Such a change can be caused by a local temperature increase Ribbon slat deformed and to the surface contour of the component to be reinforced.
  • the Glass transition point of the thermoplastic used Plastic should be above 100 ° C, begin during the flow transition area above 160 ° C should to ensure reliable handling.
  • the local heating of the flat ribbon lamella can, for example, with the help of a hot air dryer respectively.
  • thermoplastic from the group of polyolefins, vinyl polymers, polyamides, polyesters, Polyacetals, polycarbonates and thermoplastic polyurethanes and ionomers.
  • the carrier fibers are useful as carbon fibers trained by a high modulus of elasticity award.
  • the base fibers can also be aramid fibers, Glass fibers, polypropylene fibers and the like contain or consist of these.
  • Ribbon slats on one across a component edge component to be reinforced is according to the invention suggested that the ribbon slat in its over the intermediate edge leading to the component edge to one above the glass transition point of the thermoplastic Heated binder temperature, in the heated state by the edge angle of the component appropriate angle and bent before or after cooling on the component over the component edge is glued on using an adhesive layer.
  • Binder matrix allows the flat ribbon slats in the to apply the prestressed state to a component surface.
  • the flat strip slats can be used with their projecting beyond the component surface to be reinforced free ends in the heated state on one clamping element each open or bend and fix it.
  • the clamping elements can then be braced against each other be so that the flat strip slat in prestressed Condition on the component surface can.
  • a distance can be used to clamp the clamping elements from the component surface to be reinforced Clamping mechanism can be provided.
  • the tensioning mechanism can only be at one end of the flat strip lamella attack if the other end through a suitable Clamping element fixed to the component surface becomes.
  • thermoplastic according to the invention Binder matrix the possibility of the free ends the flat strip slat under the influence of Pressure and heat in a wave or zigzag shape too press.
  • the slat ends are deformed into one with a Glue filled component recess inserted so that the zigzag areas with the pasty glue fill in and after the adhesive has hardened with it form a positive connection.
  • Binder matrix can also be used Use reinforcement of columnar components.
  • the adhesive consisting of epoxy resin improve, it may be beneficial if the flat ribbon slat on their adhesive side surface of the binder exposing the surface of the fiber for example by roughening or grinding is liberated.
  • the flat strip slats shown in the drawing 10 are for the subsequent reinforcement of components 12, as determined by reinforced concrete structures and masonry. They are with their one broadside 14 with help an adhesive preferably made of epoxy resin 16 attached to the surface of the component and additionally with their free ends 32, 34 on component 12 anchored (Fig. 2).
  • the component 12 according to FIG. 2 is exemplified as a plate beam made of reinforced concrete, in which the Slat 10 is bow-shaped over the web 22 of the component 12 extends and thereby over the corner edges 24 of the Web 22 is bent.
  • the flat strip lamella 10 has a composite structure a variety of aligned in parallel flexible or limp support fibers 26 made of carbon and from one the supporting fibers are shear-proof with each other connecting binder matrix 28 made of a thermoplastic Plastic on.
  • the thermoplastic bandage Medium matrix 28 ensures that the flat strip lamella is relatively stiff at use temperature and through Heating up to a temperature above the glass transition point is plastically deformable.
  • Fig. 2 also when anchoring one end 32 of the flat strip lamella of plastic deformability under Temperature increase made use of.
  • the bent end 32 is glued to component 12 with adhesive 16.
  • On the other free end 34 has the flat strip lamella a zigzag-shaped deformation on the under Exposure to pressure and heat has been generated. With this end 34 immerses the flat strip lamella 10 in one recess 35 of component 12 filled with adhesive and forms when the adhesive hardens in it Recess an anchoring.
  • Fig. 5 In the embodiment shown in Fig. 5 is one Ribbon strip 10 spirally on a columnar Component 12 wound and glued to this. Around the flat ribbon slat will facilitate winding brought to an elevated temperature so that it easily brought into their spiral shape when wound up can be.
  • the invention refers to a flat ribbon slat 10 for Reinforcement of load-bearing or load-transmitting Components 12, for example made of concrete, wood, steel, Natural stone or masonry.
  • the flat strip slat 10 has a composite structure of a plurality of parallel aligned, pliable or limp Carrier fibers 26 and one of the carrier fibers are shear-resistant to one another connecting binder matrix 28. She is by means of an adhesive 16 on the broad surface attachable to the component to be reinforced.
  • the binder matrix 28 made of a thermoplastic Plastic is made.
