Den foreliggende opfindelse angår forankringsanordninger til spændte kabler, og især sådanne anordninger, ved hvilke der kan forekomme variationer i hældningen mellem anordningen og kablet, når kablet belastes.The present invention relates to anchoring devices for tensioned cables, and in particular to such devices in which variations in the inclination between the device and the cable may occur when the cable is loaded.

5 Sådanne kabler er f.eks. kabler, som udgør trækstag på broer.Such cables are e.g. cables which form the drawbar on bridges.

De overbelastninger, som påføres disse broer, efter at deres stag er sat på plads, kan faktisk i nogen grad deformere de ophængte brobaner og dermed hældningen af kablerne i forhold til deres forankringsanordninger eller omvendt.Indeed, the overloads applied to these bridges after their brackets are inserted may deform to some extent the suspended bridges and thus the inclination of the cables relative to their anchoring devices or vice versa.

10 På samme måde, og oftere, vil hældningen af et sådant ubelastet kabel afvige fra hældningen af kablet, når det underkastes en belastning, og det er ofte vanskeligt at anslå den nøjagtige værdi af sidstnævnte hældning under den indledende ubelastede forankring af kablet eller at give kablet den endelige ønskede 15 hældning, selv om den er kendt med nøjagtighed i forvejen.10 Similarly, and more often, the inclination of such an unloaded cable will differ from the inclination of the cable when subjected to a load, and it is often difficult to estimate the exact value of the latter inclination during the initial unloaded anchoring of the cable or to provide cable the final desired slope, although it is known with accuracy in advance.

Positionstolerancerne for de stykker, som er bestemt til at overføre kræfterne fra stagene til brobanerne, er sådanne, at der forekommer parasitiske variationer af hældningen af samme størrelsesorden som de tidligere fremkaldte.The position tolerances of the pieces intended to transfer the forces from the stakes to the bridge paths are such that parasitic variations of the slope of the same magnitude as those previously elicited occur.

20 De forskellige variationer af hældningen er generelt lokaliseret i en relativt kort afskåret ende af kablet anbragt i niveau med dets forbindelse med et stift hoved af kablet, et hoved, som kaldes forankringshoved, og som anvendes til at sikre kabelforankringen på en anlægsplade, som omfattes af anordningen.The various variations of the slope are generally located at a relatively short cut end of the cable aligned with its connection to a rigid head of the cable, a head called anchorage head, which is used to secure the cable anchorage on an abutment plate comprising of the device.

25 De spændinger, som fremkommer derved, er koncentreret i denne afskårne ende og kan være tilstrækkeligt høje til lokalt at reducere modstanden af kablet eller endog fremkalde trætheds-brud af kablet.The resulting stresses are concentrated at this cut end and may be sufficiently high to locally reduce the resistance of the cable or even to cause fatigue breakage of the cable.

For at fjerne denne ulempe har det allerede været foreslået » at placere et kuglehoved mellem forankringshovedet og dets anlægsplade, som er gennemboret således, at kablet kan føres igennem.Kuglehovedet er fast forbundet med forankringshovedet 5 og kan samvirke med en komplementær kugleskål, som bæres af pladen.To remove this disadvantage, it has already been proposed to "place a ball head between the anchor head and its abutment plate, which is pierced so that the cable can be passed through. plate.

Kablets donkraft er selv monteret på kuglehovedet omkring dette kabel.The jack of the cable itself is mounted on the ball head around this cable.

En sådan løsning er kun acceptabel ved svage belastninger, og 10 den har den ulempe, at kuglehovedet"tabes”,d.v.s. efterlades i forankringsanordningen.Such a solution is acceptable only at low loads, and it has the disadvantage that the ball head is "dropped", i.e., left in the anchoring device.

I en kendt variant af denne løsning f.eks. son vist i ER-B-2507232 angiver kablets donkraft forankringshovedet og er ikke monteret på kuglehovedet i faSt forbindelse med -forankringshovedet,men på et andet kugle-15 hoved, der er større end det første, og som selv går ind i en anden kugleskål, som bæres af den første. Denne udformning gør det muligt at gøre donkraften koaksial med forankringshovedet, selv når denne skråner i forhold til den vinkelrette på de plane bæreflader af pladen og af kugleskålene, og da at 20 udøve træk på det således skrå kabel, men denne løsning muliggør ikke ændring af hældningen af forankringshovedet under belastning.In a known variant of this solution e.g. as shown in ER-B-2507232, the cable jack indicates the anchor head and is not mounted on the ball head in solid connection with the anchor head, but on another ball head 15 which is larger than the first and which itself enters a different ball cup , which is carried by the first. This design allows the jack to be coaxial with the anchoring head, even when it slopes relative to the perpendicular to the plane carriers of the plate and of the ball cups, and then to exert tensile on the thus inclined cable, but this solution does not allow the change of the inclination of the anchor head under load.

Det er især formålet med opfindelsen at gøre sådanne ændringer under belastningen mulige.In particular, it is an object of the invention to make such changes under load possible.

25 Dette formål opnås ved, at forankringsanordningerne af den nævnte art ifølge opfindelsen omfatter endnu en donkraft anbragt omkring forankringshovedet og en konveks . sfærisk /- binders tø tning i fast forbindelse med dette’ hoved og indrettet til at samvirke med en ringformet understøtning på 30 pladen, og de er i det væsentlige ejendommelige ved,at de omfatter en ringformet skulder, som igen støtter på den frie en-This object is achieved by the fact that the anchoring devices of the kind according to the invention comprise another jack placed around the anchor head and a convex. spherical / binder support in conjunction with this head and arranged to cooperate with an annular support of the plate, and they are substantially peculiar in that they comprise an annular shoulder which in turn supports the free end.

3 de af forankringshovedet, og som på den side, der vender ind imod pladen, er afgrænset af en anden konveks sfærisk understøtning koncentrisk med den første, og ved, at donkraften er placeret mellem pladen og skulderen og omfatter en konkav sfærisk under-5 støtning, som er egnet til at samvirke tæt med skulderens konvekse sfæriske understøtning for under belastning at muliggøre en glidning af denne skulder i forhold til donkraften.3 of the anchoring head, which, on the side facing the plate, is bounded by a second convex spherical support concentric to the first, and in that the jack is located between the plate and the shoulder and includes a concave spherical support , which is suitable for cooperating closely with the shoulder's convex spherical support to allow for under-loading of this shoulder relative to the jack.

Ved de foretrukne udførelsesformer er man kommet frem til den 10 ene og/eller den anden af følgende anordninger:In the preferred embodiments, one and / or the other of the following devices have been found:

Skulderen er monteret aftageligt på forankringshovedet, især ved skruning, og en væske under tryk er anbragt mellem de samvirkende sfæriske understøtninger på skulderen og donkraften.The shoulder is removably mounted on the anchorage head, especially by screwing, and a pressurized fluid is placed between the cooperating spherical supports on the shoulder and the jack.

15 Opfindelsen omfatter, ud over de ovennævnte væsentlige arrangementer, andre arrangementer, som med fordel kan anvendes samtidig, og som vil blive forklaret nærmere i det følgende.The invention includes, in addition to the above-mentioned essential arrangements, other arrangements which can be advantageously used simultaneously and which will be explained in more detail below.

Opfindelsen skal i det følgende forklares nærmere ud fra et eksempel på en foretrukken udførelsesform og under henvisning 20 til tegningen.The invention will now be explained in more detail from an example of a preferred embodiment and with reference to the drawing.

På tegningen viser fig. 1, skematisk, et aksialt snit gennem en kabelforankringsanordning ifølge opfindelsen, efter at kablet har fået en hældning under belastning og forud for retnings-25 korrektionen af forankringshovedet, og fig. 2 og 3 i hovedsagen samme anordning, henholdsvis under og efter korrektionen.In the drawing, FIG. 1 is a schematic axial section through a cable anchoring device according to the invention after the cable has been inclined under load and prior to the directional correction of the anchor head; and FIG. 2 and 3 in the main same device, respectively during and after the correction.

4 På i og for sig kendt måde afsluttes spændkablet 1, som f.eks.* kan være beregnet til trækstag på en bro, med et fast hoved 2 med et udvendigt gevind.4 In a manner known per se, the clamping cable 1, such as * may be intended for drawbar on a bridge, is terminated with a fixed head 2 with an external thread.

Det er dette hoved 2, som skal forankres til en fast væg 3 5 i metal eller armeret beton, og hvori der er boret et hul 4 med en akse X, som tillader passage af kablet 1, eller, mere præcist, til en ringformet metallisk anlægsplade 5, der igen støtter på den massive væg 3 og er gennemboret som denne.It is this head 2 which is to be anchored to a fixed wall 35 in metal or reinforced concrete, and in which a hole 4 is drilled with an axis X which permits passage of the cable 1, or, more precisely, to an annular metallic abutment plate 5, which in turn rests on the solid wall 3 and is pierced like this.

Til dette formål er hovedet 2 eller forankringshovedet omgivet 10 af en møtrik 6, som er skruet på hovedet, og som selv har en konveks sfærisk bæreflade 7, som kan hvile på en på. pladen 5 dertil indrettet ringformet bæreflade 8, der er koaksial med hullet 4, og som i hovedsagen er keglestubformet.For this purpose, the head 2 or the anchor head 10 is surrounded by a nut 6 which is screwed on the head and which itself has a convex spherical support surface 7 which can rest on one. the plate 5 thereto is provided with annular support surface 8 which is coaxial with the hole 4 and which is generally cone-shaped.

Forankringsanordningen omfatter endvidere: 15 En ringformet skulderdel 9 fast forbundet med den frie ende af hovedet 2 og afgrænset i retning mod pladen 5 af en anden konveks sfærisk bæreflade 10, som er koncentrisk med bærefladen 7, og en donkraft 11, som omgiver hovedet 2 og er indskudt aksialt mellem pladen 5 og skulderdelen 9.The anchoring device further comprises: An annular shoulder portion 9 firmly connected to the free end of the head 2 and bounded towards the plate 5 by another convex spherical support surface 10 which is concentric with the support surface 7 and a jack 11 surrounding the head 2 and is inserted axially between the plate 5 and the shoulder portion 9.

20 Til dette fomål omfatter donkraften 11 selv:For this purpose, jack 11 itself comprises:

En ringformet fod 12, der enten kontinuerligt eller med mellemrum ligger an imod pladen 5, et ringformet hoved 13 med en konkav sfærisk bæreflade 14, som kan ligge an imod den konvekse sfæriske bæreflade 10, 25 hydrauliske eller pneumatiske organer 15 med stempel og cylinder til at forbinde hovedet 13 og foden 12 på en sådan måde, at der kan udøves en stor og afbalanceret styret spredekraftAn annular foot 12, either continuously or at intervals, abutting the plate 5, an annular head 13 having a concave spherical support surface 14 which may abut against the convex spherical supporting surface 10, 25 hydraulic or pneumatic means 15 with piston and cylinder for connecting head 13 and foot 12 in such a way that a large and balanced controlled spreading force can be exerted

5 eller adskillelseskraft mellem de to elementer.5 or separation force between the two elements.

De to sfæriske bæreflader 10 og 14 har samme krumningsradier, og i hvert fald den ene af disse flader er udformet i et hårdt og ikke-deformerbart materiale. De er bearbejdet og behandlet 5 på en sådan måde, at de let kan glide den ene mod den anden under belastning, og således, at aksen af hovedet 2 kan rette sig nøjagtigt ind efter kablet 1, der er fastgjort til dette hoved, endog når kablet belastes hårdt.The two spherical supporting surfaces 10 and 14 have the same radius of curvature, and at least one of these surfaces is formed of a hard and non-deformable material. They are machined and processed 5 in such a way that they can easily slide one against the other under load, and so that the axis of the head 2 can align exactly with the cable 1 attached to this head, even when the cable is severely loaded.

Til dette formål kan der med fordel mellem disse to overflader 10 anbringes et flydende smøremiddel såsom motorolie.For this purpose, a liquid lubricant such as engine oil can advantageously be arranged between these two surfaces 10.

Dette smøremiddel presses ud imellem de nævnte overflader under et højt tryk (f.eks. fra 500 til 1.000 bar) gennem.rørledninger 16 og fordelingsrør 17 og opsuges igen under udstrømning langs kanterne af den ringformede bæreflade> som smøres, ved hjælp 15 af bløde ringformede skørter 18 og af udsugnings- eller recirkuleringsrør 19. For enkelheds skyld er elementerne 16 - 19 kun vist på fig. 2.This lubricant is pressed out between said surfaces under a high pressure (e.g., from 500 to 1,000 bar) through conduits 16 and distribution tubes 17 and is again aspirated outwardly along the edges of the annular support surface which is lubricated, by means of soft 15 annular skirts 18 and of suction or recirculation tubes 19. For simplicity, the elements 16 - 19 are shown only in FIG. 2nd

Skulderdelen 9 er fortrinsvis monteret ubevægeligt på hovedet 2, f.eks. ved skruning, således at den kan genanvendes ligesom 20 donkraften 11 for successivt at kunne korrigere de forskellige retninger af hovederne 2.The shoulder portion 9 is preferably mounted motionless on the head 2, e.g. by screwing so that it can be reused like the jack 11 to be able to successively correct the different directions of the heads 2.

Den beskrevne forankringsanordning virker på følgende måde: Når kablet 1 er bragt på plads på det pågældende bygværk, er hovedet 2 af dette kabel forankret på den massive væg 3 koaksialt 25 med hullet 4 med en akse X, og møtrikken 6 er rettet koaksialt med dette hul med sin bæreflade 7 hvilende på bærefladen 8 af pladen 5.The anchoring device described works as follows: When the cable 1 is placed in place on the building in question, the head 2 of this cable is anchored on the solid wall 3 coaxially 25 with the hole 4 with an axis X, and the nut 6 is aligned coaxially therewith. hole with its support surface 7 resting on the support surface 8 of the plate 5.

Efter at bygværket er sat under belastning, indtager aksen Y af kablet 1 en skrå position, der hælder med en vinkel α i forhold 30 til aksen X (fig. 1).After the construction is under load, the axis Y of the cable 1 occupies an oblique position inclined at an angle α with respect to the axis X (Fig. 1).

DK 159623 BDK 159623 B

66

Det er da nødvendigt at korrige hældningen af hovedet 2 med samme vinkel <x for at undgå dannelse af uønskede spændinger i forbindelseszonen mellem kablet 1 og hovedet 2. Det er 5 nødvendigt til dette formål at fjerne møtrikken 6 fra pladen 5, som den trykker kraftigt imod på grund af trækkraften i kablet 1, da anlægsfladerne 7 og 8 ikke kan glide mod hinanden under belastning.It is then necessary to correct the inclination of the head 2 at the same angle <x to avoid the formation of undesirable stresses in the connection zone between the cable 1 and the head 2. It is necessary for this purpose to remove the nut 6 from the plate 5 which it presses strongly. against because of the traction in the cable 1, since the abutment surfaces 7 and 8 cannot slide against each other under load.

Til dette formål bringer man - efter at have bragt skulderen 9 10 og donkraften 11 på plads - sidstnævnte under tryk, hvilket har til følge, at skulderen 9 skubbes, som vist med pilene F, og dermed trækkes møtrikken 6 bort fra pladen 5 (fig. 2).For this purpose - after bringing the shoulder 9 10 and the jack 11 into place - the latter is pressurized, which causes the shoulder 9 to be pushed, as shown by the arrows F, and thus the nut 6 is pulled away from the plate 5 (fig. 2).

På samme tid smører man grænsefladen mellem de sfæriske bæreflader 10 og 14 på den ovenfor beskrevne måde.At the same time, the interface between the spherical supports 10 and 14 is lubricated in the manner described above.

15 Da muligheden for glidning under belastning således er opnået mellem bærefladerne 10 og 14, vil der helt automatisk foregå en opretning mellem akserne X og Y.15 Since the possibility of sliding under load is thus obtained between the supporting surfaces 10 and 14, a alignment will automatically occur between the axes X and Y.

Det er derefter tilstrækkeligt at udløse trykket på donkraften, så at møtrikken 6 påny kommer til anlæg imod pladen 5 i en 20 position, hvor den ligger nøjagtigt på linie med aksen Y (fig.3).It is then sufficient to release the pressure on the jack so that the nut 6 reappears against the plate 5 in a position where it is exactly aligned with the axis Y (Fig. 3).

Man kan derefter afmontere og inddrage skulderdelen 9 og donkraften 11 med henblik på at anvende disse på et andet forankringshoved .The shoulder section 9 and the jack 11 can then be removed and retracted for use on another anchor head.

Som følge heraf, og uanset hvilken udførelsesform der vælges, 25 opnår man til slut forankringsanordninger, hvis opbygning og funktion i tilstrækkelig grad fremgår af det i det foregående beskrevne.Accordingly, and regardless of which embodiment is selected, anchoring devices are finally obtained, the structure and function of which are sufficiently apparent from the foregoing.

Disse anordninger har mange fordele sammenlignet med de hidtil kendte, især den omstændighed, at de gør det muligt nøjagtigt under belastning at rette forankringshovederne ind efter kablerne, som de afslutter, på en meget økonomisk måde, efter-5 som de eneste sfæriske bæreflader 7, som blivende anvendes, kan udformes i et mindre kostbart materiale, da der ikke er noget krav om glidning under belastning på deres niveau, hvorimod de sfæriske bæreflader 10 og 14, som er indrettet til at glide den ene mod den anden under belastning, kan være re-10 lativt kostbare, da de skal kunne genanvendes.These devices have many advantages over the known ones, especially the fact that they allow precisely under load to align the anchoring heads to the cables which they terminate in a very economical manner, as the only spherical supports 7, used permanently can be formed in a less expensive material, since there is no requirement for sliding under load at their level, whereas the spherical supporting surfaces 10 and 14 arranged to slide one against the other under load can be relatively expensive as they must be recyclable.

Som det er indlysende, og som det iøvrigt fremgår af det foregående, er opfindelsen ikke begrænset til den viste udførelsesform, men omfatter tværtimod alle varianter inden for det i kravene angivne område.As is obvious, and as will be apparent from the foregoing, the invention is not limited to the embodiment shown, but, on the contrary, encompasses all variants within the scope of the claims.
