Description
DK 163890 BDK 163890 B
Opfindelsen angår et fleksibelt,: lukket rørbundt bestående af et antal parallelt med hinanden forløbende, sammenbundtede formstofrør, hvor rørbundtets enkelte rør er sammenfattede ved hjælp af forbindelses-5 midler.The invention relates to a flexible, closed tube bundle consisting of a plurality of parallel, interconnected plastic tubes in which the individual tubes of the tubular bundle are joined by means of connecting means.
Fra det tyske patentskrift nr. 33 08 482 kendes et fleksibelt rørbundt af enkelte formstofrør, hvor enkeltrørene efter deres fremstilling sammenfattes på en sådan måde, at de ved siden af hinanden beliggende 10 rør med linieformet berøring ligger an mod hinanden, og som et rørbundt er omgivet af et dæklag, der over enkeltrørenes længde er fast forbundet med disses tilstødende vægområder. Med denne metode opnås et forholdsvis stift, men dog oprulleligt rørbundtelement, der på grund 15 af dets fleksibilitet også kan trækkes ind i allerede eksisterende rørsystemer.German Patent Specification No. 33 08 482 discloses a flexible tube bundle of single plastic tubes in which the individual tubes, after their manufacture, are summarized in such a way that the adjacent tubes of linear contact abut one another and as a tube bundle is surrounded by a cover layer which is fixed over the length of the individual tubes to their adjacent wall areas. With this method a relatively rigid, yet retractable tube bundle element is obtained which, due to its flexibility, can also be drawn into pre-existing pipe systems.
Fra tysk brugsmønster nr. 82 13 407 kendes endvidere et rørbundt, der tjener til indførsel i en kabelkanal. Dette rørbundtelement er opbygget af flere enkelt-20 rør, der ved hjælp af ud i ét stykke med rørene udformede afstandsstykker er forbundet med hinanden til en måtte. Disse afstandsstykker er fleksible og tillader, at rørene lægges an mod hinanden på en sådan måde, at ved siden af hinanden liggende rør under linieberøring ligger an mod hinanden over 25 deres længde. De ved hjælp af afstandsstykkerne indbyrdes forbundne rør skal i sammensvinget stilling trækkes ind i en kabelkanal. Dette er imidlertid forbundet med vanskeligheder, idet sammensvingningen af rørene sker direkte ved indtrækningen i kabelkanalen og der derfor kræves egnede anordninger 30 hertil. Endvidere medfører det løst omgivende yderrør, at rørbundtet efter sammenlægningen af rørene får en sådan fleksibilitet, at indtrækningen af rørbundtet, især ved længere indtrækningsstrækninger, vanskeliggøres eller endog umuliggøres. Formålet med opfindelsen er derfor at udforme et rør-35 bundtelement på en sådan måde, at dets enkeltrør er fast forbundne med hinanden, og at der med forbindelsen af enkeltrørene opnås en forøget fleksibilitet af rørbundtet, således at 2Furthermore, from German usage pattern No. 82 13 407 is known a tube bundle which serves for insertion into a cable duct. This tube bundle element is made up of several single tubes which are connected to one another by means of one-piece spacers formed with the tubes. These spacers are flexible and allow the pipes to touch each other in such a way that adjacent pipes, during line contact, abut each other over their length. The tubes interconnected by means of the spacers must be pulled into a cable channel in the twisted position. However, this is associated with difficulties, as the tubing is swung directly upon entry into the cable duct and therefore suitable devices 30 are required. Furthermore, the loosely surrounding outer tube causes the tube bundle to have flexibility after the merging of the tubes so that the retraction of the tube bundle, especially during longer retraction distances, is made difficult or even impossible. The object of the invention is therefore to design a pipe bundle element in such a way that its single tubes are firmly connected to each other and that with the connection of the individual tubes an increased flexibility of the tubular bundle is obtained, so that 2

en oprulning af rørbundtet med lille oprulningsradius samt en uhindret indtrækning af det lukkede rørbundtelement i beskyttelsesrør, f.eks. i kabelkanaler, er mulig. Hertil foreslås ifølge opfindelsen, at forbindelsesmidlerne er flek-5 sible bånd, der er fastgjort tilnærmelsesvis tangentialt på ydersiden af ved siden af hinanden anbragte enkeltrør på en sådan måde, at enkeltrørene, når forbindelsesmidlerne indtager en strakt stilling, befinder sig i en defineret afstand fra hinanden i rørbundtet.a winding of the bundle with a small winding radius as well as an unobstructed retraction of the closed tube bundle element in protective tubes, e.g. in cable channels, is possible. According to the invention, it is proposed that the connecting means be flexible bands which are attached approximately tangentially to the outside of adjacent single pipes in such a way that when the connecting means assume a stretched position, the single pipes are at a defined distance from each other in the tube bundle.
10 Det lukkede rørbundt kan fremstilles kontinuert i ubegrænset længde, idet rørbundtets enkeltrør først fremstilles og dé som forbindelsesmidler mellem ved siden af hinanden liggende rør tjenende bånd umiddelbart derefter støbes på enkeltrørene. Denne fremstillingsmåde kan f.eks. ske ved 15 en koekstrusionsfremgangsmåde.The closed tube bundle can be made continuously for an unlimited length, the single tube of the tube bundle being first manufactured and then as connecting means between adjacent tubes serving strips immediately thereafter cast on the single tubes. This method of production can e.g. is done by a coextrusion procedure.
Ved rørbundtet ifølge opfindelsen bibeholder enkeltrørene deres oprindelige fleksibilitet, og på grund af de båndformede forbindelsesmidler mellem enkeltrørene kan rørbundtet oprulles med en minimal oprulningsradius på f.eks.In the tube bundle according to the invention, the single tubes retain their original flexibility, and because of the band-shaped connecting means between the single tubes, the tubular bundle can be wound up with a minimum winding radius of e.g.
20 en tromle. Dersom rørbundtets enkeltrør efter lægningen skal adskilles fra hinanden, kan det som forbindelsesmiddel på-støbte bånd nemt løsnes fra rørene ved, at påsvejsningsstedet bearbejdes med et skærende værktøj, således at det fleksible bånd skilles fra enkeltrørets overflade.20 and a drum. If, after laying, the single tube of the tubular bundle is to be separated from the tubes, the strip cast as a connecting means can easily be detached from the tubes by machining the welding site with a cutting tool so that the flexible strip is separated from the surface of the single tubing.
25 Endvidere kan en omhylning om rørbundtet tjene som forbindelsesmidler, idet omhylningen er fast forbundet med de udvendigt beliggende områder af omkredsfladerne af de i rørbundtet sammenfattede enkeltrør. Afstanden mellem enkeltrørene i et sådant fremstillet rørbundt svarer til afstanden 30 mellem enkeltrør, der er forbundne med hinanden ved hjælp af de i hovedkravet angivne fleksible bånd. Der støbes således i dette tilfælde ingen enkeltbånd mellem ved siden af hinanden beliggende enkeltrør, idet båndet i stedet som en omhylning føres rundt om de udvendigt beliggende områder af rørenes 35 omkredsflader og forbindes med disse. Enkeltrørene er således her i overført forstand optaget af et bredt bånd, hvor disse enkeltrør er fikserede i den bestemte afstand fra hinanden i 3Furthermore, a casing about the tubular bundle can serve as connecting means, the casing being firmly connected to the exterior regions of the circumferential surfaces of the single tubes summarized in the tubular bundle. The distance between the single tubes in such a bundle of tubes corresponds to the distance 30 between single tubes connected to each other by means of the flexible bands specified in the main claim. Thus, in this case, no single strip is molded between adjacent single tubes, the strip being guided instead as a casing around the exterior regions of the circumferential surfaces of the tubes 35 and connected thereto. The single tubes are thus in the transmitted sense taken up by a wide band where these single tubes are fixed at a certain distance from each other for 3 seconds.

rørbundtet. Afstanden bestemmes af bredden af båndområderne mellem hver to ved siden af hinanden liggende enkeltrør, og på denne måde opnås den samme fleksibilitet af det lukkede rørbundt.tube bundle. The distance is determined by the width of the band areas between each two adjacent single pipes, and in this way the same flexibility of the closed tube bundle is obtained.
5 Det kan endvidere være fordelagtigt som forbindel sesmidler at væLge fleksible båndafsnit, der er fast anbragte afsnitsvis over længden af ved siden af hinanden liggende enkeltrør på de udvendigt beliggende områder af disses omkredsflader. Ved denne foranstaltning opnås en fleksibilitet af 10 rørbundtet i alle retninger. Disse båndafsnit anbringes med bestemte mellemrum på de udvendigt beliggende områder af omkredsfladerne af rørbundtets ved siden af hinanden liggende enkeltrør. Mellemrummene vælges fordelagtigt således, at rørbundtet har den nødvendige stivhed, men at der alligevel 15 kan opnås en optimal fleksibilitet. Den nødvendige stivhed kan f.eks. opnås ved, at der anvendes strakte bånd. Båndaf-snittene af disse bånd indføres automatisk i produktionslinien under fremstillingen af enkeltrørene.Further, it may be advantageous as connecting means to select flexible strip sections which are fixedly sectioned over the length of adjacent single tubes on the externally located regions of their circumferential surfaces. By this measure, a flexibility of the 10 bundles of bundles is obtained in all directions. These strip sections are arranged at certain intervals on the outer regions of the circumferential surfaces of the adjacent tubes of adjacent tubes. The gaps are advantageously chosen so that the tube bundle has the necessary stiffness, but that an optimal flexibility can still be achieved. The required stiffness can e.g. is achieved by using stretched bands. The ribbon sections of these strips are automatically inserted into the production line during the manufacture of the single tubes.
Rørbundtet kan bestå af forskellige antal af rør 20 med forskellig diameter, og der kan alt efter ønske sammenfattes et lige eller et ulige antal af enkeltrør.The tube bundle may consist of different numbers of tubes 20 of different diameters and, as desired, an equal or an odd number of single tubes can be summarized.
Anbringelsen af de som forbindelsesmidler tjenende, i længderetningen forløbende fleksible bånd på den udad-vendende del af enkeltrørenes omkredsflader kan ske ved 25 coekstrusion, hvor sammensvejsningen af båndene med røroverfladen sker i termoplastisk tilstand. Man kan dog også først fremstille enkeltrørene og derefter forbinde disse i længderetningen med båndene. I dette tilfælde kan båndene udstøbes på overfladen af enkeltrørene, hvorunder varmen 30 fra den støbte smelte smelter røroverfladen i det begrænsede område, hvorved forbindelsen opnås. Ved sammenklæbning af båndene med røroverfladen anvendes et egnet klæbemiddel eller bindemiddel på klæbestedet, hvorunder båndene under kraftudøvelse skal anbringes på den pågældende 35 røroverflade.The longitudinally flexible flexible strips which serve as connecting means are applied to the outwardly extending circumferential surfaces of the single tubes by coextrusion, where the strips are welded to the tube surface in a thermoplastic state. However, one can also first produce the single tubes and then connect them longitudinally with the bands. In this case, the strips may be cast on the surface of the single tubes, under which the heat 30 from the molded melt melts the tube surface in the confined area, whereby the connection is obtained. When bonding the strips to the pipe surface, a suitable adhesive or binder is used at the adhesive site, under which the strips are to be applied to the respective pipe surface under force.
På tegningen er skematisk anskueliggjort udførelseseksempler for rørbundtet, og her viser:In the drawing, exemplary embodiments of the pipe bundle are shown schematically, and here shows:
DK 163890 BDK 163890 B
4 fig. 1 rørbundtet ifølge opfindelsen med tangentialt anbragte forbindelsesmidler, fig. 2 rørbundtet med delvis omhylning som forbindelsesmidler, og 5 fig. 3 rørbundtet med fleksible båndafsnit som forbindelsesmidler.4 FIG. 1 shows the pipe bundle according to the invention with tangentially arranged connecting means; FIG. 2 shows the tube bundle with partial casing as connecting means; and FIG. 3 the tube bundle with flexible strip sections as connecting means.
Det i fig. 1 viste rørbundt 1 består af fire enkeltrør 11, 12, 13, 14. Mellem hver to enkeltrør 11 og 12, 12 og 14, 14 og 13, 13 og 11, forløber et bånd 2 som forbindelsesmiddel. 10 Båndet 2 har mellem svejsesteder 21, 22, ved hvilke det er forbundet med enkeltrørene 11, 12, 13, 14, en bredde, der på grund af båndafsnittenes bøjelighed tillader enkeltrørene f.eks. ved oprulning af disse at indtage en sådan stilling i rørbundtet, at de ligger praktisk taget fladt ved siden af 15 hinanden i rørbundtet 1. Rørbundtets bøjelighed er yderligere forøget ved, at enkeltrørene 11, 12, 13, 14 som formstofrør i sig selv er bøjelige. Ved det særlige valg af antallet af enkeltrør og af bredden af forbindelsesmidlerne kan der fremstilles et rørbundt, hvor enkeltrørene ligger fladt ved siden 20 af hinanden, selvom de ved hjælp af forbindelsesmidlerne er sammenfattede til et lukket rørbundtelement.The FIG. 1 is comprised of four single tubes 11, 12, 13, 14. Between each two single tubes 11 and 12, 12 and 14, 14 and 13, 13 and 11, a band 2 extends as a connecting means. The band 2 has between the welding locations 21, 22 at which it is connected to the single tubes 11, 12, 13, 14, a width which, due to the flexibility of the band sections, allows the single tubes e.g. by rolling them up to take such a position in the tube bundle that they lie practically flat next to each other in the tube bundle 1. The flexibility of the tube bundle is further increased by the fact that the individual tubes 11, 12, 13, 14 as plastic tubes are themselves flexible . By the particular choice of the number of single tubes and of the width of the connecting means, a tube bundle can be made, the single tubes lying flat next to each other, even though they are joined together by means of the connecting means to a closed tube bundle element.
I fig. 2 er rørbundtet 1 vist med en delvis omhylning 3 som forbindelsesmiddel. Kappen 3 er fast forbundet med størstedelen af omkredsen af enkeltrørene 11, 12, 13, 14. Kun 25 den del af røromkredsen af hvert rør, der vender ind mod rørbundtets indre, er ikke dækket af omhylningen. Mellem enkeltrørene 11, 12, 13, 14 forløber forbindelsesstykker 31 af omhylningen 3, der kan varieres i deres bredde på samme måde som båndet 2 i fig. 1. Forbindelsesstykkerne 31 er ligeledes 30 båndformede og bøjelige og tillader således også ved denne udformning, at rørbundtet 1 på grund af den forøgede bøjelighed nemt kan henholdsvis oprulles eller trækkes ind i beskyttelsesrør.In FIG. 2, the tube bundle 1 is shown with a partial casing 3 as the connecting means. The sheath 3 is firmly connected to the majority of the circumference of the individual tubes 11, 12, 13, 14. Only 25 of the portion of the tube circumference of each tube facing the interior of the tube bundle is not covered by the casing. Between the single pipes 11, 12, 13, 14 are connecting pieces 31 of the casing 3 which can be varied in their width in the same way as the belt 2 in FIG. 1. The connecting pieces 31 are likewise 30 shaped and flexible and thus also permit in this configuration that the tube bundle 1 can easily be retracted or retracted into protective tubes because of the increased flexibility.
I fig. 3 er rørbundtet 1 vist med fleksible bånd-35 afsnit 4 som forbindelsesmidler. Enkeltrørene 11, 12, 13, 14 er her afsnitsvis forbundne med hinanden ved hjælp af de fleksible båndafsnit 4, der er anbragte i ønskede afstande fra 5 hinanden og i de længdeforhold på omkredsen af rørene, der bestemmer rørbundtets fleksibilitet.In FIG. 3, the tube bundle 1 is shown with flexible band sections 4 as connecting means. The individual tubes 11, 12, 13, 14 are here sectionally connected to each other by means of the flexible band sections 4 arranged at desired distances from each other and in the longitudinal conditions on the circumference of the tubes which determine the flexibility of the tube bundle.
