Definitions
- This invention relates to a method for prestressing a steel structure, both on a new construction and preferably on an existing steel structure, especially on bridge structures.
- the European railway Administrations confirm that there are approximately 220,000 railway bridges in Europe alone and that they are located in a wide variety of climatic areas.
- About 22% of these are metal or steel structures, which are often referred to as iron bridges.
- 3% are cast iron bridges, 25% are welded steel structures, and 53% are made of steel, and approx.
- CFRP Carbon Fiber Reinforced Polymers
- the object of this invention is to provide a method for prestressing a steel structure and also a steel structure prestressed therewith. This prestressing is intended to prevent the formation of cracks on a new or existing steel structure, or to crack existing cracks or to stop or at least slow their further growth.
- FIG 1 a steel structure in the form of an iron bridge 1 with sub-struts 2 is shown, with the lowest horizontal steel beam 3 Train is loaded.
- iron bridges there are always steel girders that are under pressure and those that are under tension. Bending moments also have an effect, especially if the bridge is temporarily loaded, for example if a train is rolling over it. Every axle load causes vibrations and this contributes to the fatigue of the material, so that over the years cracks can appear in the steel beams, which weaken the steel beams more and more.
- the aim is to stop this process or at least slow it down.
- CFRP tapes carbon fiber reinforced polymer tapes
- CFRP tapes are exceptionally strong under tensile stress and are also not subject to corrosion, they are ideal for reinforcing steel beams under tensile stress.
- the most efficient way would be to pre-tension steel girders with tensile loads using such belts.
- Proposals have become known for subsequently reinforcing concrete structures with prestressed bands in order to improve their tensile strength.
- the strips are strongly pre-tensioned using a special device and, in this pre-tensioned state, moved up to the concrete structure and laminated onto the concrete using epoxy resin adhesives. After the adhesive has cured, the device that created and maintained the tension is removed, after which the pre-tensioned CFRP tape permanently applies its tension to the structure.
- the bridge behind Figure 1 has a sub-strut 2, that is to say the lowest horizontal strut 3 is loaded with tension, and it can be reinforced by means of CFRP bands 4, for which the procedure is as follows.
- a CFRP band 4 is at its two end regions over a section or over the whole Length of a structural part that is subjected to tension is connected to the same in a traction-locking manner.
- a CFRP band 4 is stretched over the entire length of the underside of the horizontal lower steel beam 3, the end anchorages 5 being fastened on both sides in the vicinity of the ends of the steel beam 3.
- the band 4 is stretched slack.
- a lifting element 7 is installed between the steel beam 3 and the CFRP band 4 in the middle of the CFRP band 4, that is to say over half the length.
- This lifting element 7 can be a hydraulically, pneumatically, electrically or mechanically actuated lifting element 7, which offers such a translation that high lifting forces can be generated, for example a few 10k Newtons. Short reaction paths are now generated with comparatively long action paths.
- CFRP tape 4 not only a single CFRP tape 4 has to be attached, but a whole set of CFRP tapes 4 can be installed over the width of the bridge, or also sections of the length of the bridge several CFRP tapes 4 in succession or CFRP tapes 4 which overlap in length can be attached, which are positioned next to one another and run parallel to one another, or even overlap in height, that is to say they can lie one above the other or can cross.
- the strips 4 are not laid on the steel girders exactly in the direction of travel, but at a slightly oblique angle to them, so that the strips 4 intersect.
- FIG 2 you can see the steel structure Figure 1 after insertion a lifting element 7. It was mounted under the slackly attached CFRP band 4, for example by means of a mechanical connection to the steel beam 3, by welding or screwing.
- This lifting element 7 can be constructed in the manner of a jack, so that it can be raised hydraulically by means of an external hydraulic pump by temporarily connecting a hydraulic line to the lifting element 7. Sufficiently large forces can be generated with an appropriate translation.
- the lifting is then secured by means of a mechanical jack or by means of mechanical documents. Such mechanical documents are installed after the working stroke of the lifting element 7, which in this case is raised somewhat above the ultimate tensile stress, next to the same between the band 4 and the steel beam 3 to be reinforced.
- the lifting element 7 is relieved again somewhat, so that the target tension is reached and the supporting force is then absorbed by the documents.
- the lifting element 7 can also be operated pneumatically. Then a compressor hose can be coupled, and the extension of the lifting element 7 takes place due to pneumatic pressure with a sufficient ratio.
- an electrical variant of a lifting element 7 is also conceivable in that an EL motor inside generates a sufficiently large lifting force by means of a short translation, for example by means of spindles and levers. In this case, only an electrical line needs to lead to the lifting element 7, and it can be easily adjusted if necessary.
- the Figure 3 shows the steel structure Figure 1 after the insertion of two lifting elements 7. If two lifting elements 7 are used, they are advantageously extended at the same time, so that the tension builds up uniformly over the length of the belt. As an alternative, the one lifting element 7 can be extended a little, then the second a similarly small distance, then again the first, then again the second, etc., so that the tractive force gradually alternates to a certain extent by the two lifting elements 7 is produced.
- the Figure 4 shows a steel structure in the form of an iron bridge with upper struts 6 with a slack CFRP band 4 connected to it.
- the attached CFRP band 4 runs along the lowest horizontal steel girder, in practice, of course, there are several such steel girders, the longitudinal the bridge, and each is equipped with at least one CFRP band 4, each with two end anchors 5, which at the ends of the band 4 connect this to the structure or the said steel girder.
- the Figure 5 shows this steel structure Figure 4 after the insertion of three lifting elements 7, which are arranged distributed over the length of each CFRP band 4 and are again extended at the same time, or else the two outer ones are extended a little and then the middle is slightly further, so that a uniform tension over the entire length of the CFRP tape 4 is generated.
- the Figure 6 finally shows a steel structure in the form of an iron bridge with an arched sub-strut 2.
- a tensile force acts on the arched longitudinal beams 8 at the lower end of the bridge.
- CFRP bands 4 can be laid and attached along these curved beam supports 8.
- a single CFRP band 4 runs over the entire length of the bridge along the lower support arch 8 and is firmly attached to the steel support 8 at both end regions of the anchoring elements 5 attached there Bridge 1 connected.
- Five lifting elements 7 are used here distributed over the belt length. These are all raised uniformly in order to generate a voltage build-up in the CFRP band 4 that is as uniform or homogeneous as possible. This tensioning force is then introduced into the structure 1 via the anchoring elements 5.
- Such reinforcements can in some cases close cracks or gaps in steel structures, i.e. in the elements that are subject to tension. In other cases, further growth of these cracks and crevices can be prevented, or at least the weakening process can be slowed down considerably, and overall the structures can be decisively strengthened and stabilized so that their lifespan is extended or, if necessary, the load capacity is increased.

Description
Diese Erfindung betrifft ein Verfahren zum Vorspannen eines Stahl-Bauwerkes, und das sowohl an einer Neukonstruktion sowie vorzugsweise an einem bestehenden Stahl-Bauwerk, vorallem an Brückenkonstruktionen. Gemäss einer Studie von
Versuche an der EMPA in CH-Dübendorf zeigten, dass sich mit der Applikation von Kohlefaser-verstärkten Polymeren (CFRP = Carbon Fiber Reinforced Polymers) die Stahlträger im Grundsatz verstärken lassen. Diese CFRP werden mittels Klebestoffen an den Stahlträgern befestigt und vermögen eine Zugbelastung aufzunehmen, was die Rissbildung verlangsamt oder sogar stoppt. Klebstoffe eignen sich allerdings vielerorts nur bedingt, denn Stahl wird durch die Sonneneinstrahlung stark erhitzt und das kann den Klebstoff an seine Glastransformationsgrenze bringen. Zu beachten sind in diesem Zusammenhang die Publikationen
Ein weiterer Problemkreis bildet die galvanische Korrosion. Obwohl CFRP nicht korrosiv sind, bilden sie in Verbindung mit Stahl galvanische Zellen. Dann gibt es viele genietete Eisenbrücken. Bei diesen besteht das Problem darin, wie man die flachen CFRP Bänder am bestens an den Eisenträgern befestigt. Und schliesslich muss oft auch auf den Denkmalschutz Rücksicht genommen werden, indem etwa gefordert wird, dass historisch bedeutsame Bauwerke bei Bedarf wieder in ihren ursprünglichen Zustand zurückversetzt werden können müssen, was mit aufgeklebten CFRP Bändern kaum realisierbar ist. Und schliesslich wäre es erwünscht, die Bauwerke nicht nur zu verstärken, sondern unter eine Vorspannung zu setzen, um damit bereits bestehende Risse und Spalten völlig zu verschliessen und ein Weiterwachsen dieser Risse und Spalten dauerhaft zu unterbinden. Eines der wichtigsten Aufgaben eines Verstärkungssystems ist daher die sachdienliche Wahl des mechanischen Verankerungssystems, sodass dieses genügend Klemmkraft entwickelt, einer minimalen Korrosion unterworfen ist, möglichst keine direkte Berührung der CFRP Bänder mit dem Stahl bedingt, und die Stress-Einleitung in das Verankerungssystem graduell erfolgt.Another problem area is galvanic corrosion. Although CFRP are not corrosive, they form galvanic cells when combined with steel. Then there are many riveted iron bridges. The problem with these is how best to attach the flat CFRP straps to the iron girders. And finally, historical preservation often has to be taken into account, for example by demanding that historically significant buildings can be restored to their original state if necessary, which is hardly feasible with CFRP tapes glued on. And finally, it would be desirable not only to reinforce the structures, but also to put them under a prestress in order to completely close existing cracks and gaps and to permanently prevent these cracks and gaps from growing. One of the most important tasks of a reinforcement system is therefore the appropriate choice of the mechanical anchoring system so that it develops sufficient clamping force, is subject to minimal corrosion, if possible does not cause the CFRP bands to come into direct contact with the steel, and the stress is gradually introduced into the anchoring system.
Die Aufgabe dieser Erfindung ist es, ein Verfahren zum Vorspannen eines Stahl-Bauwerkes anzugeben, sowie auch ein damit vorgespanntes Stahl-Bauwerk. Dabei soll mittels dieser Vorspannung die Rissbildung an einem neuen oder bestehenden Stahl-Bauwerk verhindert werden, oder schon vorhandene Risse sollen geschlossen werden oder deren weiteres Wachsen soll gestoppt oder mindestens verlangsamt werden.The object of this invention is to provide a method for prestressing a steel structure and also a steel structure prestressed therewith.

Mittels solcher Verstärkungen können Risse oder Spalte in Stahlbauwerken, das heisst in den Elementen, die auf Zug belastet sind, in manchen Fällen geschlossen werden. In anderen Fällen kann ein weiteres Wachsen dieser Risse und Spalten verhindert werden, oder mindestens kann der Schwächungsprozess wesentlich verlangsamt werden, und insgesamt können die Bauwerke entschieden verstärkt und stabilisiert werden, sodass ihre Lebensdauer verlängert wird, oder bedarfsweise die Belastungsfähigkeit gesteigert wird.Such reinforcements can in some cases close cracks or gaps in steel structures, i.e. in the elements that are subject to tension. In other cases, further growth of these cracks and crevices can be prevented, or at least the weakening process can be slowed down considerably, and overall the structures can be decisively strengthened and stabilized so that their lifespan is extended or, if necessary, the load capacity is increased.
