Den foreliggende opfindelse angår en rørgennemføring til et tag og hvor den nedre ende af en øvre rørdel, som strækker sig op over taget, er forbundet,med den øvre ende af en nedre rørdel, som er afsluttet under taget, ved hjælp 5 af et bøjeligt rørafsnit, idet samlingen mellem taget og rørgennemføringen er dækket ved hjælp af en krave og det bøjelige rørafsnit strækker sig fra tagets underside til tagets overside.The present invention relates to a pipe feed to a roof and wherein the lower end of an upper pipe portion extending over the roof is connected to the upper end of a lower pipe portion terminated under the roof by means of a flexible pipe section, the joint between the roof and the pipe penetration being covered by a collar and the flexible pipe section extending from the underside of the roof to the top of the roof.

Sådanne rørgennemføringer anvendes, når aftræk fra 10 afløbsfaidstammer, ventilationsrør fra luftkonditioneringsanlæg, aftræk fra emhætter, osv. skal føres gennem et tag til en bygnings yderside.Such pipe penetrations are used when ducts from 10 drainage fins, ventilation ducts from air conditioners, extractors from hoods, etc. must be passed through a roof to the exterior of a building.

Ved disse konstruktioner er det kendt at anvende et harmonikalignende, bøjeligt rørafsnit inden i bygningen som 15 en forlængelse af det stive rør, som er afsluttet under taget. Den nedre ende af det rør, som passerer gennem taget, er forbundet med den øvre del af dette bøjelig afsnit. Selve gennemføringen sker ved hjælp af en såkaldt taggennemføringsplade, som er forsynet med en konisk eller kalotformet 20 krave, den såkaldte rodkegle.In these designs, it is known to use a harmonic-like, flexible pipe section within the building as an extension of the rigid pipe completed under the roof. The lower end of the pipe passing through the roof is connected to the upper portion of this flexible section. The actual process is carried out by means of a so-called roof insertion plate, which is provided with a conical or callous-shaped collar, the so-called root cone.

På markedet findes der taggennemføringsplader, der med hensyn til formen af pladen er tilpasset efter forskellige former for tagdækninger, og størrelsen er f.eks. i tilfælde af et tegltag afpasset efter formen af en tagsten, og 25 i midten af taggennemføringspladen er den koniske del til gennemføringen af røret. På selve det gennemførte rør er der omtrent ved rørets midte et kraveparti, den såkaldte rørkonus, som tæt omgiver røret, og som bliver placeret over rodkeglen og derved dækker spalten mellem åbningen i rodkeglen 30 og røret. Ved dette system kan røret altså placeres lodret uanset tagets hældning ved at udforme åbningen i rodkeglen under den ønskede vinkel.In the market there are roof penetration plates which, with regard to the shape of the plate, are adapted to different types of roofing, and the size is e.g. in the case of a tile roof adapted to the shape of a roof tile, and 25 in the center of the roof entry plate is the tapered portion for the passage of the pipe. On the pipe itself, there is approximately at the center of the pipe a collar portion, the so-called pipe cone, which closely surrounds the pipe, which is placed above the root cone, thereby covering the gap between the opening in the root cone 30 and the pipe. In this system, the pipe can thus be placed vertically regardless of the slope of the roof by forming the opening in the root cone at the desired angle.

På markedet findes der også gennemføringsbælge af gummi og hvis nedre ende er forsynet med en aluminiumflange, 35 medens den øvre ende af bælgen tætnes i forhold til røret ved hjælp af et spændebånd. Disse gennemføringsbælge har intet harmonikaafsnit, som er ført gennem til tagets underside, og hvortil røret kan fastgøres ved hjælp af et spænde-Also available on the market are rubber guide bellows, the lower end of which is provided with an aluminum flange, while the upper end of the bellows is sealed relative to the tube by means of a clamping strap. These lead-through bellows have no harmonica section which is passed through to the underside of the roof and to which the pipe can be attached by means of a clamp.

2 bånd. Når der anvendes gennemføringsbælge bæres røret af tagkonstruktionen på tages underside, således at røret bliver lodret. Som regel er der kun snæver plads under taget, af hvilken grund monteringen bliver ubekvem.2 tapes. When conducting bellows are used, the pipe is carried by the roof structure on the underside of the roof, so that the pipe becomes vertical. As a rule, there is only limited space under the roof, for which reason the mounting becomes inconvenient.

5 Rørgennemføringen ifølge opfindelsen er ejendommelig ved, at det bøjelige rørafsnit er forsynet med en rundtgåen-de flange, som er fremstillet af bøjeligt materiale, og som er placeret hen over spalten mellem kanten af åbningen i tagdækningsmaterialet og det bøjelige rørafsnit.The pipe penetration according to the invention is characterized in that the flexible pipe section is provided with a circular flange made of flexible material, which is located across the gap between the edge of the opening in the roofing material and the flexible pipe section.

10 Der findes i det mindste 50 forskellige tagdæknings materialer med forskellige udformninger. Ved hjælp af den foreliggende opfindelse kan individuelt udformede rodplader undgås, hvorved der opnås besparelser i omkostningerne ved fremstilling af støbeforme, og forhandlere behøver kun at 15 lagerføre ét produkt.10 There are at least 50 different roofing materials with different designs. By means of the present invention, individually designed root plates can be avoided, thereby saving savings in the cost of making molds, and dealers need only stock one product.

Rørgennemføringen ifølge opfindelsen er egnet for alle tagdækningsmaterialer, såsom tagplader,tegltage,og tagpaptage osv. Formen af tagdækningsmaterialets ydre overflade kan have en hvilken som helst udformning, f.eks korrugeret.The pipe penetration according to the invention is suitable for all roofing materials, such as roofing sheets, tile roofs and roofing, etc. The shape of the outer surface of the roofing material can be of any configuration, for example corrugated.

20 Gennemføringen kan også eftermonteres i et eksisterende, færdiggjort tag.20 The finish can also be retrofitted in an existing, finished roof.

Opfindelsen skal i det følgende beskrives nærmere under henvisning til tegningen, på hvilken:The invention will now be described in more detail with reference to the drawing, in which:

Fig. 1 viser komponenterne, som anvendes i rørgennem-25 føringen ifølge opfindelsen set fra siden, fig. 2 viser i perspektiv den næsten færdigt samlede rørgennemføring med taget delvis gennemskåret, og fig. 3 viser i perspektiv den færdige rørgennemføring .FIG. 1 is a side elevational view of the components used in the pipe conduit of the invention; FIG. Fig. 2 is a perspective view of the almost complete pipe feed-through with the roof partially cut through; and Figs. 3 shows in perspective the finished pipe penetration.

30 Det bøjelige, harmonikalignende rørafsnit 1 er f.eks.The flexible, harmonic-like pipe section 1 is e.g.

fremstillet af gummi. Ved begge ender har det to cylindriske afsnit 2,2' med forskellige diametre, hvilke afsnit er placeret ved siden af hinanden og forbundet ved hjælp af et bryst 3. På denne måde er det let at forbinde det harmonika-35 lignende afsnit med to forskellige rørstørrelser ved om nødvendigt at afskære det ydre, mindre cylindriske afsnit 2. I den øvre del af røret ved omkring trediedelspunktet for rørhøjden regnet fra toppen er der en fremstående flange 4, sommade of rubber. At both ends, the two cylindrical sections have 2.2 'of different diameters, which sections are located side by side and connected by a chest 3. In this way it is easy to connect the harmonica-like section with two different pipe sizes by cutting the outer, smaller cylindrical section 2. If necessary, in the upper part of the pipe at about the third point of the pipe height calculated from the top there is a protruding flange 4 which

3 er støbt ud i ét med røret rundt om dette. En rundtgående, plan ring 5 af aluminium eller bly kan være fastgjort til harmoniokarørets 1 flangedel 4. Ringen 5 er tynd og kan i forbindelse med montagen let bøjes, så den svarer til den 5 ydre overflade af tagdækningsmaterialet 6. Ringen 5 kan være fastgjort til flangen 4 f.eks. ved limning eller den kan være separat. Ringen kan være forudmonteret på flangen 4. Når konstruktionen installeres, anbringes harmonikarøret i det hul, som er fremstillet i tagdækningsmaterialet 6, så den 10 fremstående flange 4 hviler mod tagdækningen 6. Mellem den fremstående flange og tagdækningsmaterialet placeres der tætningspasta 7. Skruer eller nitter 8 isættes ved boring gennem aluminiums- eller blyringen 5 med små mellemrum, så der opnås en vandtæt samling.3 is cast into one with the tube around this. A circular, flat ring 5 of aluminum or lead may be attached to the flange portion of the harmonic tube 1. The ring 5 is thin and can be easily bent in connection with the mounting, corresponding to the outer surface of the roofing material 6. the flange 4 e.g. by gluing or it can be separate. The ring can be pre-mounted on the flange 4. When the structure is installed, the harmonic tube is placed in the hole made in the roofing material 6 so that the 10 protruding flange 4 rests against the roofing 6. Between the protruding flange and the roofing material, sealing paste 7. Screws or rivets are placed. 8 is inserted by drilling through the aluminum or lead ring 5 at small intervals to obtain a waterproof assembly.

15 Derefter fastgøres røret 9 til den øvre del af harmo nikarøret ved hjælp af et spændebånd 10. Herpå installeres rodkeglen 11 ved hjælp af skruer 15 på tagdækningsmaterialet. Den øverste ende af rodkeglen er forsynet med en forud fremstillet åbning, der er beliggende i et plan, der danner • 20 en passende vinkel, f.eks ca. 20*, med basispladen 12, som omgiver rodkeglen. Åbningen er så meget større end tykkelsen af røret, at den samme kegle kan anvendes både ved et fladt tag og ved tage med forskellige hældninger, f.eks. op til en hældningsvinkel på 45*. Eftersom spillerummet mellem åbnin-25 gen i tagdækningsmaterialet 6 og hamonikarøret 1 er tætnet ved hjælp af flangen 4 og ringen 5, behøver samlingen mellem basispladen 12 på rodkeglen og tagdækningsmaterialet ikke længere at være tæt.15 Then the tube 9 is secured to the upper part of the harmonica tube by means of a clamping band 10. The root cone 11 is then installed by means of screws 15 on the roofing material. The upper end of the root cone is provided with a pre-made aperture located in a plane which forms a suitable angle, e.g. 20 *, with the base plate 12 surrounding the root cone. The opening is so much larger than the thickness of the pipe that the same cone can be used both on a flat roof and on roofs with different slopes, e.g. up to an angle of inclination of 45 *. Since the clearance between the opening of the roofing material 6 and the hamonica tube 1 is sealed by the flange 4 and the ring 5, the connection between the base plate 12 of the root cone and the roofing material no longer needs to be sealed.

Keglen 12 på røret installeres til slut omkring rod-30 keglen via den øverste ende af røret. Ved den øverste kant af_xøxkeglen,'‘f'.'eks'; -ved' kraven 13, er der et cylindrisk afsnit 14, som passer stramt omkring røret 9. Den nedre kant af rørkeglen er delvis affaset, så basispladen 12 på rodkeglen under rørkeglen kan monteres Γ en stilling svarende til 35 tagets hældning samtidig med at den øverste del af røret 14 bliver lodret. Røret 9 drejes sammen med rørkeglen 13, således at den bliver lodret, hvorpå rørkeglen fastgøres til rodkeglen ved hjælp af skruer 16.The cone 12 of the tube is finally installed around the root cone via the top end of the tube. At the upper edge of the_xøx cone, '' f '.' Ex '; -by the collar 13, there is a cylindrical section 14 which fits tightly around the pipe 9. The lower edge of the pipe cone is partially beveled so that the base plate 12 of the root cone below the pipe cone can be mounted Γ a position corresponding to the inclination of the roof. the upper portion of the tube 14 becomes vertical. The tube 9 is rotated together with the tube cone 13 so that it becomes vertical, whereupon the tube cone is attached to the root cone by means of screws 16.
