Definitions
- This invention relates to a method for tempering a steel structure, both on a redesign and preferably on an existing steel structure, especially on bridge structures.
- CFRP Carbon Fiber Reinforced Polymers
- the object of this invention is to provide a method for tempering a steel structure, as well as a prestressed steel structure. It should be prevented by means of this bias the cracking of a new or existing steel structure, or already existing cracks should be closed or their further growth should be stopped or at least slowed down.
- the object is achieved by a method for tempering a steel construction, in which at least one reinforced with carbon fiber polymer- Band is connected in each case at its end regions traction with a reinforcing steel beam of the steel structure, and thereafter in a region between these end anchors at least one between the respective carbon fiber reinforced polymer band and the steel beam to be reinforced arranged lifting element substantially perpendicular to the carbon Extended fiber-reinforced polymer tape, for effecting a tensile stress between the end regions of the respective carbon-fiber reinforced polymer tape.
- a steel structure which is characterized in that at least one reinforced with carbon fiber polymer tape is connected at its end regions zugkraftschlüssig with a reinforcing steel beam of the steel structure, wherein in the area between these end regions at least a lifting element disposed between the respective carbon fiber reinforced polymer tape and the steel beam to be reinforced, by which the respective carbon fiber reinforced polymer tape is lifted by substantially perpendicularly lifting the carbon fiber reinforced polymer tape from the steel beam can be placed under tension.

- Figure 5 The steel structure of Figure 4 after the onset of three
- Figure 6 A steel structure in the form of an iron bridge with arcuate
- FIG. 1 a steel structure in the form of an iron bridge 1 is shown with sub-struts 2, wherein the lowermost horizontal steel beam 3 is loaded to train.
- iron bridges there are always steel beams that are subjected to pressure, and those that are claimed to train. Bending moments also act, especially when the bridge is temporarily loaded when, for example, a railway train rolls over it.
- Each axle load causes vibrations and these contribute to the fatigue of the material, so that over the years in the steel beams cracks can occur, which weaken the steel beams more and more. It is important to stop this process or at least slow it down.
- CFRP tapes are exceptionally strong in tensile strength and also free from corrosion, they offer the option of reinforcing tension-loaded steel beams.
- the most efficient way would be to pretension steel beams loaded with tension by means of such bands.
- Suggestions have become known to subsequently reinforce concrete structure with prestressed bands to improve their tensile strength.
- the tapes are strongly pre-tensioned by means of a special device and, in this prestressed state, moved up to the concrete structure and laminated to the concrete by means of epoxy resin adhesives. After curing of the adhesive, the device, which is the voltage created and maintained, after which the prestressed CFRP band permanently introduces its voltage into the structure.
- the bridge of Figure 1 has a sub-strut 2, that is, the lowest horizontal strut 3 is loaded on train, and it can be reinforced by means of CFPR bands 4, which is done as follows.
- a CFPR band 4 is connected at its two end regions over a portion or over the entire length of a tensile load claimed building part zugkraftschlüssig with the same.
- suitable end anchors 5 for example in the form of clamping shoes, by means of which the bands 4 are permanently mechanically and highly zugkraftschlüssig connected to the steel beam 3.
- a CFPR band 4 is stretched over the entire length of the underside of the horizontal lower steel girder 3, the end anchors 5 being fastened on both sides in the vicinity of the ends of the steel girder 3.
- the band 4 is stretched slack.
- a lifting element 7 is installed between the steel carrier 3 and the CFPR belt 4.
- This lifting element 7 may be a hydraulically, pneumatically, electrically or mechanically operable lifting element 7, which provides such a translation that high lifting forces can be generated, for example, some 10k Newton. So short reaction paths are created with comparatively long action paths.
- CFPR band 4 not only a single CFPR band 4 must be attached, but a whole host of CFPR bands 4 can be installed across the width of the bridge, or even in sections over the length of the bridge several CFPR bands 4 consecutively or overlapping CFPR tapes 4 can be attached to one another in length, which are positioned next to one another and run parallel to one another, or even overlap in height, ie lie one above the other or can intersect.
- the bands 4 are not exactly laid in the running direction of the steel beams on the same, but slightly skewed to it, so that crossings of the bands 4 arise.
- FIG 2 one sees the steel structure of Figure 1 after insertion of a lifting element 7. It was mounted under the slack stretched CFRP band 4, for example by means of a mechanical connection to the steel beam 3, by welding or screwing.
- This lifting element 7 may be designed in the manner of a jack, so that it can be hydraulically lifted by means of an external hydraulic pump by a hydraulic line is temporarily connected to the lifting element 7. With a corresponding translation, sufficiently large forces can be generated.
- the lifting is then secured by means of a mechanical pawl or by means of mechanical documents.
- Such mechanical documents are installed next to the same between the band 4 and the steel beam 3 to be reinforced after the completed stroke of the lifting element 7, which is lifted in this case slightly beyond the final tensile stress to be reached.
- the lifting element 7 is again relieved somewhat, so that the target voltage is reached and the support force is then collected from the documents.
- the lifting element 7 can also be actuated pneumatically.
- a compressor hose can be coupled, and the extension of the lifting element 7 is due to pneumatic pressure with a sufficient translation.
- an electrical variant of a lifting element 7 conceivable by an in-lying EL motor via a short translation, for example by means of spindles and levers, generates a sufficiently large lifting force. In this case, only an electric line needs to lead to the lifting element 7, and it can easily be adjusted if necessary.
- Figure 3 shows the steel structure of Figure 1 after the insertion of two lifting elements 7.
- these are advantageously extended simultaneously, so that the voltage builds evenly distributed over the tape length.
- the one lifting element 7 can be extended a short distance, then the second one just a little bit far, then again the first, then again the second, etc. so that the tensile force gradually alternately alternately generated by the two lifting elements 7 aufschaukelnd becomes.
- Figure 4 shows a steel structure in the form of an iron bridge with top struts 6 with a slack connected to him CFRP band 4.
- the attached CFRP band 4 along the lowest horizontal steel beam, where in practice, of course those are steel beams running along the bridge and each being equipped with at least one CFRP belt 4, each having two end anchors 5 which at the ends of the belt 4 connect it to the structure or said steel beam in a tractional manner.
- Figure 5 shows this steel structure according to Figure 4 after the insertion of three lifting elements 7, which are arranged distributed over the length of each CFRP tape 4 and in turn are extended simultaneously or it is first the two outer a piece extended and then the middle a little further, so that a uniform voltage over the entire length of the CFRP band 4 is generated.
- the figure 6 shows a steel structure in the form of an iron bridge with arcuate sub-strut 2.
- CFRP strips 4 can be laid and grown along these curved beam carriers 8.
- a single CFRP tape 4 extends along the entire length of the bridge along the lower carrier sheet 8 and is connected at both end regions of anchoring elements 5 attached there to the steel carrier 8 of the bridge 1.
- cracks or gaps in steel structures that is to say in the elements which are loaded on train, can be closed in some cases. In other cases, further growth of these cracks and crevices may be prevented, or at least the weakening process may be substantially slowed down and, overall, the structures may be significantly strengthened and stabilized to prolong their life or, if necessary, increase load capacity.
