Definitions
- the invention relates to a component with at least one at least in sections flat reinforcement element, the main body of the component essentially consists of a hydraulically bound matrix, and the reinforcing element at least in sections in a slot in the surface of the Base body is arranged and at least over an anchoring length in the Slot is fixed and is connected to the base body.
- the invention further relates to a method for attaching additional reinforcement on a concrete component, with at least one slot in the surface of the concrete component is generated, the slot at least in regions with a Binder is filled, a reinforcement element at least in sections made of a fiber-reinforced plastic at least in sections in the Slot is arranged and the displaced, emerging from the slot Binder is removed.
- An example of such a component is a concrete component with or without reinforcement called.
- German Patent DE-A-43 33 782 there is a method of attachment described an additional reinforcement on a reinforced concrete component, at which first grooves into the surface with the help of a high-pressure water jet of the concrete component. Reinforcement elements then become in the grooves arranged from steel. Then the grooves are again with concrete backfilled, the reinforcement elements are embedded in the concrete and so be fixed in the grooves.
- the method can only be used to a limited extent, which is due to the fact that the bond between a concrete component and a stuck reinforcement is relatively stiff. So they are in the adhesive bond possible shifts in the range below 0.2 mm, while the possible displacements of concreted ribs are in the range of 1 mm.
- the combination of a concrete reinforcement made of concrete is therefore significantly more ductile.
- the adhesive bond leaves only a relatively small amount of force into the slat. This force transmission is also strong from the existing one Concrete quality and the resulting adhesive tensile strength.
- the Slat can only be used to a maximum of 40% of the tensile strength.
- a further limitation of the application possibilities of glued fiber-reinforced Slats as additional reinforcement is that the component surface only unevenness under 5 mm with a measuring length of 2 m. Also one Use in components where shear cracks are computationally possible, i.e. for components with required shear reinforcement, is problematic because in this In the event of a so-called peeling fracture as a result of a shear crack offset. Finally, it should be noted that a glued-on reinforcement is also always must be protected from mechanical damage and also special Precautions in the event of a fire must be taken to prevent the failure To prevent reinforcement.

- the anchoring part can be attached to one be placed anywhere in the reinforcement element; proves in practice but it is advantageous if the anchoring part is on the end of the reinforcement element is arranged, or two anchoring parts each at the ends of the reinforcement element are provided.
- the slots are essentially vertical are oriented to the surface of the base body.
- the present invention lets but can also be realized with a different orientation of the slots.
- the reinforcement elements are at least over an anchoring length fixed in the slot. But it can also be used for certain applications be advantageous to have a reinforcement element along its entire length in the Fix slot.
- Reinforcement elements can be made from within the component according to the invention completely different materials are used.
- reinforcement elements made of a plastic with a fiber reinforcement, preferably in the form of carbon fibers, aramid fibers and / or glass fibers, proven.
- Such reinforcement elements are corrosion-resistant and have a very high tensile strength with a small cross-section, so that overall only relatively small slot depths are required.
- a reinforcement element can be mechanically in the Slot are fixed. As a rule, however, there is a bond between the reinforcement element and the base body in the area of the slot.
