Definitions
- the present invention relates to a
- Reinforcement device according to the preamble of claim 1 and a method for reinforcing beams according to the preamble of claim 11.
- Such supporting structures can be conventionally constructed walls made of brick or, for example, reinforced concrete walls or beams, wood, plastic or steel beams.
- tensioning means in the form of strips made of metal or fiber-reinforced plastic via end anchorages.
- tensioning means there is no flat connection of the tensioning means to the supporting structure, but only a connection to the supporting structure is provided in the two end anchoring points of the tensioning means.
- tensioning devices are conventionally included in the planning of the supporting structure, since retrofitting is practically impossible or can only be carried out at great expense, since corresponding channels have to be created in the supporting structure for the tensioning devices.
- CFRP lamellas carbon lamellas
- CFRP lamellas carbon lamellas
- They are advantageous here simple and inexpensive application of such slats, which have a higher strength than the steel slats at a much lower weight and are easier to store.
- the corrosion resistance is also better, which is why such reinforcements also for the
- the object of the present invention was to find a CFRP reinforcing lamella in which the force is introduced from the carrier into the ends in such a way that detachment is practically avoided and which is also suitable for the prestressing.
- End element Force transmission into the ends of the CFRP lamella, which can also be easily pretensioned using such an end element.
- the one trained in block form End element can now either be inserted into a recess in the carrier or in the preferred embodiment with wedge-shaped splitting with flat or rough bottom also simply glued and / or pegged to the carrier. be screwed.
- This embodiment is particularly suitable for the prestressing, which is preferably carried out directly via the carrier part. For example, this can be done by bracing against a fitting part inserted into the carrier.
- the splitting of the ends of the CFRP lamellae can preferably take place either in overlapping flags or in adjacent flags, respectively. in a combination of these two variants.
- the ends of the CFRP slats can advantageously be split at the construction site itself in the lengths and dimensions required in each case.
- This system is very universal for the reinforcement of practically any support components and can be used with or without pretension.
- Figure 1 shows the cross section through a carrier with CFRP lamella according to the invention attached to the underside.
- 2 shows the cross section through the head part of the CFRP lamella according to FIG. 1;
- FIGS. 1 and 2 show the cross section through the end of a CFRP lamella according to FIGS. 1 and 2;
- FIG. 4 shows the cross section through a carrier with a further CFRP lamella according to the invention attached to the underside;
- FIG. 5 shows the cross section through the head part of the CFRP lamella according to FIG. 4;
- FIG. 6 shows the schematic cross section through an alternative head part of a CFRP lamella according to the invention
- FIG. 7 shows a schematic cross section through a further alternative head part of a CFRP lamella according to the invention.
- Fig. 8 shows the supervision of a further alternative embodiment of the head part of a CFRP lamella.
- FIG. 1 now shows the cross section through a support 1 to be reinforced.
- the ends of the CFRP lamella 2 used for this purpose are inserted according to the invention in end elements, here anchor heads 3 and 4.
- the anchor heads 3, 4 can be used in milled or tapered recesses in the carrier 1, as shown in this figure.
- the CFRP lamella 2 is by means of Adhesive layer 5 is connected to the carrier 1 over the entire surface or partially, and the anchor heads 3, 4 are also glued to it.
- the anchor heads 3, 4 can be connected to the carrier by a transverse tensioning device 6, shown here only purely schematically, which leads to a better introduction of force via the anchor heads 3, 4 from the CFRP lamella 2 into the carrier 1.
- Cross-tensioning device 6 can be made, for example, via threaded rods or dowels guided through the carrier 1 and the anchor heads 3, 4.
- the reinforcement device formed from the CFRP lamella 2 and the anchor heads 3, 4 can now also be simply pretensioned, as is shown schematically on the right-hand side of FIG.
- an angle fitting 7 can be attached to the underside of the support 1, to which a tension rod 8, which is connected at one end to the anchor head 4, engages.
- both anchor heads 3, 4 must be equipped with such a tensioning device for pretensioning.
- the clamping device is attached before gluing and can, after the adhesive bond between the CFRP lamella 2 has hardened. the anchor heads 3, 4 and the support 1 can be removed again.
- FIG. 2 now shows the cross section through one of the anchor heads 3.
- the cuboid anchor head 3 there are preferably three guide or Holding slots 9 arranged one above the other, which can accommodate the end of the CFRP lamella 2, which is divided into three flags 2 *, as shown in FIG. 3.
- the holding slots 9 are here arranged upwards and downwards wedge-shaped and have transverse bores 10. These holes 10 provide additional anchoring points for the adhesive, with which the flags 2 'of the CFRP lamella 2 are connected to the holding slots 9.
- the big advantage lies in the splitting of the end of the lamella 2 into the flags 2 '. This splitting is preferably carried out in the fiber direction of the lamellae, and it is thus advantageously achieved to enlarge the adhesive surface without the strength properties of the CFRP lamellae 2 being impaired.
- the adhesive area is tripled compared to a conventional lamella, which is only glued to the carrier at its end, and is still tripled compared to the known solution with a wedge-shaped recess in the carrier and adhesive bridges!
- a transverse reinforcement 11 should preferably be attached, which is shown only schematically in FIG is indicated.
- this transverse reinforcement 11 can be carried out by means of threaded rods which are guided through corresponding bores in the anchor head 3 and braced via nuts.
- a threaded bore 12 is made in the anchor head 3, for example, into which a pretensioning device can be screwed, as is shown schematically in FIG.
- FIG. 3 shows one end of the CFRP lamella 2 with the lamella end split into three flags 2 '.
- the CFRP lamella can be split by conventional means after cutting to the desired length into the desired number, approximately equal flags 2 ', for example by means of a planer or knife.
- the advantage here is that the quality of the splitting is subject to relatively low requirements; the division into the corresponding number of flags 2 ′ is essential in order to achieve the increase in area for the connection to the anchor head 3.
- FIG. 4 shows the cross section through a carrier 1 with a reinforcement device according to the invention, which is attached to the underside (tension side) and consists of a CFRP lamella 2 with anchor heads 12 and 13 attached to the ends.
- the anchor heads 12, 13 are now designed in such a way that that the CFRP lamella 2 practically emerges from the anchor heads 12, 13 at the level of the adhesive layer 5, and that they do not therefore have to be arranged sunk in the underside of the carrier 1, but also, for example, glued flatly to this underside can be.
- the transverse tensioning devices 6 indicated in FIG. 1 can also be attached here in order to bring about a higher contact pressure and thus a higher tensile strength of the connection between the anchor heads 12, 13 and the underside of the beam.
- These anchor heads 12, 13, like the embodiment already described above, can also be easily preloaded.
- FIG. 5 now shows the cross section through an anchor head 12 and the corresponding arrangement of the holding slots 9.
- the bottom slot 9 ' is parallel to the outer wall 12' of the anchor head 12 resting on the support 1, the remaining slots 9 are at an acute angle for this purpose arranged in a fan shape pointing towards the outside.
- this arrangement brings the same advantages as already described by enlarging the bonding surface of the CFRP lamella 2, and on the other hand enables the anchor heads 12, 13 to be applied evenly without additional recesses on the carrier 1.
- transverse reinforcement means 11 as shown schematically in FIG. 2, in order to prevent the armature heads 12, 13 from bending open or tearing open in the region of the exit of the CFRP lamella 2.
- the anchor heads 3.4, respectively. 12, 13 is suitable on the one hand metal, which has high strength, easy workability and good
- CFRP lamella 2 is split here into two superposed flags 2 ′, which come to rest on the outside of a wedge-shaped anchor head 14. You can in turn be connected to the surface of the anchor head 14 by gluing.
- the split flags 2 'of the end of the CFRP lamella 2 are held in an anchor head formed from plates 15 arranged one above the other, as shown in longitudinal section in FIG.
- an anchor head formed from plates 15 arranged one above the other, as shown in longitudinal section in FIG.
- FIG. 8 also shows the supervision of a further embodiment of the end of the CFRP lamella 2.
- the flags 2 ' are not formed one above the other, but are formed side by side.
- the splitting is preferably carried out along the fiber direction of the CFRP lamella 2.
- the reinforcement devices according to the invention are particularly suitable for the renovation of existing concrete support structures, such as ceilings or
- Bridge girders can also be used for all known applications of conventional CFRP slats, such as masonry and Wooden structures.
- the simple prestressing enables the strength properties of the CFRP lamellas to be utilized to a greater extent than in the previously known processes.
- the preload causes a pre-pressing to take place on the tension side of an existing support element, which is particularly advantageous, for example, in the case of bridge girders.
