Abstract

1. A flexible, fully-enclosed multiple subducting system consisting of a number of parallel, bundled plastic subducts in which the individual subducts in the bundle are linked by connecting elements, characterized in that the connecting elements (2, 3, 4) are flexible bands running in longitudinal direction which are attached roughly tangentially to the outer circumference of the adjacent individual subducts (11, 12, 13, 14) in such a way that the individual subducts (11, 12, 13, 14) are maintained at a defined distance from one another inside the bundle (1) when the bands (2, 3, 4) are fully extended.

Description

Oppfinnelsen vedrører en fleksibel, lukket rørsammenstilling av et antall innbyrdes parallelt forløpende, buntete plastrør, idet de enkelte rørene i rørbunten er holdt sammen av et forbindelsesmiddel. The invention relates to a flexible, closed pipe assembly of a number of mutually parallel, bundled plastic pipes, the individual pipes in the pipe bundle being held together by a connecting means.

Fra tysk patentsøknad P 3308482.2-12 er det kjent en fleksibel rørsammenstilling av plastrør, idet enkeltrørene etter tilvirkningen blir sammenføyd slik, at innbyrdes sammenstøtende rør ligger an mot hverandre med linjekontakt og er omgitt som rørbunt av et dekksjikt, idet dekksjiktet er fast forbundet stort sett langsgående med det tilhørende veggområdet av enkeltrørene. Med denne framgangsmåten blir det oppnådd en forholdsvis stiv, men viklbar rørforbindelse, som på grunn av sin fleksibilitet også kan trekkes inn i eksisterende rørsystem. From German patent application P 3308482.2-12, a flexible pipe assembly of plastic pipes is known, in that the individual pipes are joined after manufacture in such a way that mutually colliding pipes abut each other with line contact and are surrounded as a pipe bundle by a cover layer, the cover layer being mostly firmly connected longitudinally with the associated wall area of the individual pipes. With this procedure, a relatively rigid but flexible pipe connection is achieved, which, due to its flexibility, can also be pulled into the existing pipe system.

Fra tysk bruksmønster 8213407 er det kjent en rørsammenstilling, som tjener til innføring i en kabelkanal. Denne rørsammenstillingen er bygd opp av flere enkeltrør, som er innbyrdes forenet til ei matte ved hjelp av avstandssteg som er utformet i ett med rørene. Disse avstandsstegene er fleksible og tillater at enkeltrørene kan legge seg slik an mot hverandre at sammenstøtende rør får langsgående linjeanlegg. De innbyrdes med avstandssteg forbundne rørene skal i sammenført tilstand trekkes inn i en kabelkanal. Her opptrer imidlertid problemer, da sammenfør ingen av rørene må skje direkte ved inntrekkingen i kabelkanalen og følgelig krever tilsvarende forholdsregler. From German utility model 8213407, a pipe assembly is known, which serves for insertion into a cable channel. This pipe assembly is made up of several individual pipes, which are interconnected to form a mat by means of spacers that are designed as one with the pipes. These distance steps are flexible and allow the individual pipes to be placed against each other in such a way that colliding pipes have a longitudinal line system. The pipes connected to each other with distance steps must be pulled into a cable duct in the joined state. However, problems arise here, as joining none of the pipes must take place directly when they are pulled into the cable duct and consequently require corresponding precautions.

Dessuten er det en risiko for at de løst anliggende ytter-rørene etter sammenfør ingen fører til en slik fleksibilitet for rørbunten, at det særlig på lange inntrekkingsstrekninger blir vanskeligere å trekke rørbunten inn i en kabelkanal, dersom det i det hele tatt er mulig. In addition, there is a risk that the loosely attached outer pipes after all do not lead to such flexibility for the pipe bundle, that it becomes more difficult to pull the pipe bundle into a cable duct, especially on long retracting stretches, if it is possible at all.

Hovedformålet med oppfinnelsen er således å utforme en rørsammenstilling slik, at enkeltrørene i sammenstillingen er innbyrdes fast forenet og at det med forbindelsen av enkeltrørene blir oppnådd en økt fleksibilitet for rørbunten, slik at det er mulig å vikle rørbunten med liten vikleradius, såvel som trekke den uhindret inn i vernerør, f.eks. i kabelkanaler. The main purpose of the invention is thus to design a pipe assembly in such a way that the individual pipes in the assembly are mutually firmly united and that with the connection of the individual pipes an increased flexibility is achieved for the pipe bundle, so that it is possible to wind the pipe bundle with a small winding radius, as well as to pull it unhindered into protective pipes, e.g. in cable channels.

Ifølge oppfinnelsen- kan dette oppnås ved hjelp av de trekk som er angitt i den karakteriserende delen av patentkrav According to the invention, this can be achieved by means of the features specified in the characterizing part of the patent claim

Den lukkete rørbunten kan tilvirkes kontinuerlig i ubegrenset lengde, idet enkeltrørene i rørbunten blir tilvirket først og umiddelbart deretter blir forbindelsesmidlene, som tjener som, bånd mellom de enkelte rørene, påsprøytet. Denne tilvirkningen kan f.eks. skje ved såkalt koekstrusjon. The closed tube bundle can be manufactured continuously to an unlimited length, as the individual tubes in the tube bundle are manufactured first and immediately afterwards the connecting means, which serve as ties between the individual tubes, are sprayed on. This production can e.g. happen by so-called coextrusion.

Ved den nye oppbygningen av rørbunten beholder enkeltrørene sin opprinnelige fleksibilitet og på grunn av de båndformete forbindelsesmidlene som befinner seg mellom enkeltrørene kan den spoles opp med minimal vikleradius, f.eks. på en trommel. With the new structure of the tube bundle, the individual tubes retain their original flexibility and due to the band-shaped connecting means located between the individual tubes, it can be wound up with a minimal winding radius, e.g. on a drum.

Dersom en under eller etter leggingen må skille enkeltrørene ut av rørbunten, kan de påsprøytete båndene lett løsnes fra de opptilliggende rørene, idet påsveisingsstedet blir bearbeidet enkelt med et skjæreverktøy og dermed båndet skilt fra enkeltrørets overflate. If, during or after laying, the individual pipes have to be separated from the pipe bundle, the sprayed bands can be easily detached from the adjacent pipes, as the welding point is easily processed with a cutting tool and thus the band separated from the surface of the individual pipes.

Som forbindelsesmiddel kan det dessuten brukes en omhylling av rørbunten, som er fast forbundet med ytre omkretsområder av enkeltrørene som er sammenføyd i rørbunten. Avstanden mellom enkeltrørene innbyrdes i en slik tilvirket røcbunt tilsvarer avstanden mellom enkeltrørene, som er sammenføyd med de fleksible båndene ifølge patentkrav 1. Herunder blir det altså ikke påsprøytet enkeltbånd mellom sammenstøtende enkeltrør, men båndet blir ført som omhylling om ytterdelen av røromkretsen og fast forbundet med denne. Prinsipielt opptar her et bredt bånd enkeltrørene i den lukkete rørbunten, idet disse enkeltrørene holdes i tilsvarende avstand fra hverandre i rørbunten. Avstanden blir bestemt av bredden på båndområdene mellom to sammenstøtende enkeltrør og på denne måten blir den samme fleksibiliteten til den lukkete rørbunten oppnådd. As a connecting means, a sheathing of the tube bundle can also be used, which is firmly connected to the outer circumferential areas of the individual tubes joined in the tube bundle. The distance between the individual pipes in such a manufactured flue bundle corresponds to the distance between the individual pipes, which are joined with the flexible bands according to patent claim 1. Here, therefore, no single band is sprayed on between clashing individual tubes, but the band is guided as a wrap around the outer part of the pipe circumference and firmly connected with this. In principle, a wide band here occupies the individual pipes in the closed pipe bundle, as these individual pipes are kept at a corresponding distance from each other in the pipe bundle. The distance is determined by the width of the band areas between two abutting individual pipes and in this way the same flexibility of the closed pipe bundle is achieved.

Videre kan det være fordelaktig å velge som forbindelsesmiddel fleksible båndavsnitt, som er fast anordnet avsnittsvis langs tilstøtende enkeltrør på ytre områder av disse. På denne måten blir det oppnådd en fleksibilitet for rørbunten i alle retninger. Disse båndavsnittene blir påføyd i bestemte avstander på ytre omkretstråder på de respektive sammenstøtende enkeltrørene i rørbunten. Disse avstandene blir herunder hensiktsmessig valgt slik, at rørbunten har den nødvendige styrken og likevel gir en optimal fleksibilitet. Den nødvendige styrken kan f.eks. oppnås ved at det blir brukt strekte bånd. Båndavsnittene av disse båndene blir automatisk innbragt på passende steder langs produksjonslinja under samtidig tilvirkning av enkeltrørene. Furthermore, it can be advantageous to choose as connecting means flexible belt sections, which are fixedly arranged in sections along adjacent individual pipes on their outer areas. In this way, flexibility is achieved for the pipe bundle in all directions. These strip sections are added at specific distances on the outer circumferential wires of the respective abutting individual pipes in the pipe bundle. These distances are appropriately chosen below so that the pipe bundle has the necessary strength and still provides optimal flexibility. The required strength can e.g. achieved by using stretched bands. The strip sections of these strips are automatically brought into suitable places along the production line during the simultaneous production of the individual pipes.

Rørbunten kan ta et varierende antall rør med forskjellig diameter, idet det etter behov kan sammenføyes et like eller ulike antall enkeltrør. The pipe bundle can take a varying number of pipes with different diameters, as an equal or different number of individual pipes can be joined as required.

Påføringen av de langsløpende, fleksible båndene, som virker som forbindelsesmiddel, på den ytre omkretsen av enkeltrørene kan skje ved såkalt "koekstrusjon", idet sammensveisingen av båndene med røroverflata skjer i termoplastisk tilstand. Det ligger imidlertid også innenfor oppfinnelsens ramme å tilvirke enkeltrørene først og deretter forbinde dem med de langsløpende båndene. I dette tilfelle kan båndene sprøytes på overflata av enkeltrørene, idet varmen fra den påsprøytete smeltemassen smeltes inn i røroverflata og på denne måten skaper en forbindelse. Ved sammenklebingen av båndene med røroverflata brukes et tilsvarende klebemiddel henholdsvis vedhengsmiddel på klebestedene, idet båndene blir presset mot de tilhørende deler av røroverflata. The application of the longitudinal, flexible bands, which act as a connecting agent, to the outer circumference of the individual pipes can take place by so-called "co-extrusion", as the welding of the bands to the pipe surface takes place in a thermoplastic state. However, it is also within the scope of the invention to manufacture the individual pipes first and then connect them with the longitudinal bands. In this case, the bands can be sprayed onto the surface of the individual pipes, as the heat from the sprayed melt melts into the pipe surface and in this way creates a connection. When gluing the bands together with the pipe surface, a corresponding adhesive or attachment agent is used at the points of adhesion, as the bands are pressed against the associated parts of the pipe surface.

I tegningen er det vist skjematisk utførelseseksempler av rørbunten i samsvar med oppfinnelsen, idet: fig. 1 viser en rørbunt med tilnærmet tangensielt påfestete forbindelsesmidler, The drawing shows schematic examples of the pipe bundle in accordance with the invention, in that: fig. 1 shows a tube bundle with approximately tangentially attached connecting means,

fig. 2 viser rørbunten med delvis omhylling med forbindelsesmiddel, mens fig. 2 shows the tube bundle with partial wrapping with connecting agent, while

fig. 3 viser rørbunten med fleksible båndavsnitt som forbindelsesmiddel. fig. 3 shows the tube bundle with flexible band sections as connecting means.

Rørbunten som er vist i fig. 1 består av fire enkeltrør 11-14. Mellom to og to enkeltrør 11 og 12, 12 og 14, 14 og 13 samt 13 og 11 er det påføyd et bånd 2 som forbindelsesmiddel. Båndet 2 har mellom sveisesteder 21, 22 på enkeltrørene 11-14 en bredde som på grunn av fleksibiliteten i båndavsnittet tillater enkeltrørene å* innta en stilling i rørbunten, f.eks. ved oppvikling, som i praksis legger rørbunten 1 flat. I tillegg øker det fleksibiliteten, at enkeltrørene 11-14 er tilvirket av fleksible plastrør. Med det spesielle valg av antallet enkeltrør såvel som valget av bredde på forbindelsesmidlet, kan det tilvirkes en rørbunn 1, hvor i praksis enkeltrørene ligger i rekke ved siden av hverandre, selv om de er sammenføyd til en lukket rørsammenstilling med forbindelsesmidlene. The tube bundle shown in fig. 1 consists of four single tubes 11-14. Between two and two individual pipes 11 and 12, 12 and 14, 14 and 13 and 13 and 11, a band 2 is added as a connecting means. The strip 2 has between welding points 21, 22 on the individual pipes 11-14 a width which, due to the flexibility of the strip section, allows the individual pipes to* occupy a position in the pipe bundle, e.g. when winding, which in practice lays the tube bundle 1 flat. In addition, it increases flexibility that the individual pipes 11-14 are made of flexible plastic pipes. With the particular choice of the number of individual pipes as well as the choice of width of the connecting means, a pipe base 1 can be produced, where in practice the individual pipes lie in a row next to each other, even if they are joined to form a closed pipe assembly with the connecting means.

I fig. 2 er rørbunten 1 forsynt med en delvis omhylling eller kappe 3 med forbindelsesmidlet. Kappa 3 er fast forbundet med den største delen av den ytre omkretsen av enkeltrørene 11-14. Bare det rørsegmentet som rager inn i det indre av rørbunten er ikke dekket av omhyllingen. Mellom enkeltrørene 11-14 d<;>anner omhyllingen fir e steg 31, som kan varieres i bredden på tilsvarende måte som bredden av båndet 2 i fig. 1. Stegene 31 er likeledes gjort båndformet fleksible og tillater dermed også ved denne oppbygningen, på grunn av den fleksibiliteten de innebærer, en tilfredsstillende oppvikling henholdsvis inntrekking av rørbunten 1 i vernerør. In fig. 2, the tube bundle 1 is provided with a partial covering or jacket 3 with the connecting means. Kappa 3 is firmly connected to the largest part of the outer circumference of the individual tubes 11-14. Only the pipe segment that protrudes into the interior of the pipe bundle is not covered by the casing. Between the individual pipes 11-14, the casing has four steps 31, which can be varied in width in a similar way to the width of the band 2 in fig. 1. The ladders 31 are likewise made flexible in the form of a band and thus also allow with this construction, due to the flexibility they entail, a satisfactory winding or retraction of the tube bundle 1 into the protective tube.

I fig. 3 er det vist en. rørbuwt 1 med: fleksible båndavsnitt 4 som f.oæ.bind^lsesmoiddel. Enkel tr øre ne lii-14 er her avsnittsvis forbumdet med! hverandre' ved<1> h.jielp' av fleksible båndavsnitt 4, idet b-åtod'aiv/s;nd>ttene er plias>s;er:t i. vilkårlig, innbyrdes avstand og i lengdeforhold på rørorokretsem,, somt bestemmer rørbuntens fleksibilitet.
