Opfindelsen angår et tagafløb af den i krav l's indledning angivne art, således som kendt fra DE-A-3.425.654.The invention relates to a roof drain of the kind specified in the preamble of claim 1, as known from DE-A-3,425,654.

Fra DE-A-2.437.191 kendes et afløb til flade tage, hvor en ringkrave med vedhængende tætningsbane er fast forbundet 5 med afløbslegemet. Ved monteringen placeres der i udløbslegemet et i ét stykke udformet opsatselement med ligeledes fast anbragt tætningsbane. Også under byggefasen er ringkraven udlagt og tætningsbanen placeret, hvilket ofte fører til en beskadigelse af disse dele og til senere 10 utætheder.DE-A-2,437,191 discloses a drain for flat roofs, in which a ring collar with a pendant sealing path is firmly connected to the drain body. During mounting, a one-piece mounting element with also fixed sealing path is placed in the outlet body. Also during the construction phase, the ring collar is laid out and the sealing path is placed, which often leads to damage to these parts and to later leaks.

Opfindelsen har til formål at tilvejebringe et afløb af den indledningsvis nævnte art, der kan fremstilles på prisbillig måde, og som uden ovennævnte ulempe er funk-tionssikker og enkel at montere.The invention has for its object to provide a drain of the kind mentioned at the outset, which can be manufactured in an inexpensive manner and which, without the aforementioned disadvantage, is functionally safe and easy to assemble.

15 Dette formål opnås ifølge opfindelsen ved de i krav l's kendetegnende del angivne foranstaltninger.This object is achieved according to the invention by the measures specified in the characterizing part of claim 1.

De fremstillingsteknisk forholdsvis krævende dele anvendes både for opsatsdelen og for afløbslegemet, hvorved fremstillingen, lagerføringen og montagen forenkles. For 20 at undgå en beskadigelse af tætningsbanen, kan afløbslege-met under byggefasen også anvendes uden ringkrave til at sikre en provisorisk dræning.The relatively technically demanding parts are used both for the mounting part and for the drain body, thereby simplifying manufacturing, storage and assembly. To avoid damage to the sealing web, the drain body during the construction phase can also be used without a ring collar to ensure a temporary drain.

Ved en foretrukken udførelsesform er der på opsatsdelen anbragt et rørstykke, som anbringes i af løbs legemet. Dette 25 rørstykke kan afkortes svarende til opsatsens ønskede højde. Ved endnu en udførelsesform er der tilvejebragt et indsatslegeme, som placeres i afløbslegemet under byggefasen. Herved er der også under byggefasen tilvejebragt en pålidelig afvanding, og samtidig er indløbet beskyttet 30 mod byggeaffald. Yderligere udførelsesformer for opfindelsen er angivet i underkravene.In a preferred embodiment, a pipe piece is arranged on the attachment member which is placed in by the body of the barrel. This piece of pipe can be shortened according to the height of the set. In yet another embodiment, an insert body is provided which is placed in the drain body during the construction phase. This also provides reliable drainage during the construction phase, and at the same time the inlet is protected against construction waste. Further embodiments of the invention are set forth in the subclaims.

Opfindelsen skal i det følgende forklares nærmere under henvisning til tegningen, på hvilken fig. 1 viser et snit gennem et i et dæk indbygget afløbslegeme med opsatsdel, og 5 fig. 2 viser et snit gennem et indbygget afløbslegeme med indsatslegeme.The invention will now be explained in more detail with reference to the drawing, in which: 1 is a sectional view of a drain body with a mounting part built into a tire; and FIG. 2 shows a section through a built-in drain body with insert body.

Afløbet har et af formstof bestående afløbslegeme 1 med et ydre, varmeisolerende lag 24, f.eks. af polyurethan, og en indre skål 25. På skålen 25 er der ved midten udformet en 10 studs 4, der fører til et her ikke vist faldrør. Over studsens åbning 3 er der anbragt et dæksel 9, som er fastgjort til skålens bund 2. Dækslet 9 har slidser 10 i sidevæggen 12 samt slidser 11 i overvæggen 13. Dette dæksel forøger på i sig selv kendt måde afløbets afløbs-15 evne og tjener tillige som ekstra si. Af løbslegemet 1 har en cirkel cylindrisk væg 40, der omgiver en vandopsamlingssump 44, og som foroven har en udadvendende flange 47.The drain has a plastics drain body 1 having an outer, heat insulating layer 24, e.g. of polyurethane, and an inner bowl 25. On the bowl 25 a 10 studs 4 are formed at the center leading to a drop pipe not shown here. A cover 9 is provided above the opening 3 of the studs, which is attached to the bottom of the bowl 2. The cover 9 has slots 10 in the side wall 12 and slots 11 in the overlay 13. This cover in a manner known per se increases the drainage ability and serves as well as extra say. Of the body 1 has a circular cylindrical wall 40 which surrounds a water collection sump 44 and which has an outwardly extending flange 47 at the top.

Af løbs legemet 1 er indstøbt i eller anbragt i en bund 30.Of the body 1 is embedded in or placed in a bottom 30.

20 En plan udad forløbende tætningsbane 5, f.eks. af poly-vinylchlorid, er fastgjort ved flangen 45 på en ringkrave 6. På flangen 45 er der udformet en cirkel cylindrisk studs 14, der er i indgreb med vandopsamlingssumpen 44, og i studsens inderside 15 er der anbragt en læbetætning 38.A planar outward sealing path 5, e.g. of polyvinyl chloride, is attached to the flange 45 on a ring collar 6. On the flange 45 is a circle of cylindrical studs 14 which engage the water collection sump 44, and on the inside 15 of the studs a lip seal 38 is provided.

25 Ringkraven 6 er ved hjælp af en ringtætning eller en læbetætning 7 tætnet mod af løbs legemet 1.The ring collar 6 is sealed against by the body 1 by means of a ring seal or a lip seal 7.

Hvis der, således som det er angivet fig. 1, er tilvejebragt et yderligere bundlag 31, placeres der i afløbsiegernet 1 en opsats 8. Denne del har en ringkrave 20, der 30 svarer nøje til ringkraven 6 i afløbets nedre del. På ringkraven 20 er der ligeledes udformet en tætningsbane 26. Desuden svarer den cirkel cylindriske vægdel 23 på en skål 33 til det tilsvarende vægområde 43 på skålen 25. På skålen 33 er der udformet et cylindrisk rør 22. Røret 22 DK 166786 B1 3 hviler med den nedre rand på skålen 25's bund 2. Dette rør 22 afkortes under montagen i afhængighed af laget 31's tykkelse. I ringkraven 20's åbning anbringes afslutningsvis en løvsi 27.If, as indicated in FIG. 1, a further bottom layer 31 is provided, a mounting 8 is placed in the drain mesh 1. This part has a ring collar 20 which corresponds exactly to the ring collar 6 in the lower part of the drain. Also on the ring collar 20 is a sealing path 26. In addition, the circular cylindrical wall portion 23 on a bowl 33 corresponds to the corresponding wall area 43 on the bowl 25. On the bowl 33 a cylindrical tube 22. The tube 22 DK 166786 B1 3 is formed with the lower rim of the bottom 2. of the bowl 25. This tube 22 is shortened during assembly, depending on the thickness of the layer 31. Finally, in the opening of the ring collar 20, a leaf screen 27 is placed.

5 I fig. 2 er det vist, hvorledes afløbet kan anvendes som provisorisk dræn under byggefasen. Til dette formål placeres afløbslegemet 1 uden ringkraven 6 i bunden 30. Provisorisk placeres et indsatslegeme 28 af f.eks. opskummet polystyrol i vandopsamlingssumpen 44. Dette legeme 28 er i 10 vid udstrækning udformet komplementært i forhold til vandopsamlingssumpen og har over dækslet 9 en åbning, hvorigennem det fra laget 30’s overflade tilstrømmende vand kan bortledes. Til sin tid fjernes indsatslegemet 28, og ringkraven 6 med tætningsbanen placeres som foreskrevet.5 In FIG. Figure 2 shows how the drain can be used as a temporary drain during the construction phase. For this purpose, the drain body 1 without the ring collar 6 is placed at the bottom 30. Provisionally, an insert body 28 of e.g. foamed polystyrene in the water collection sump 44. This body 28 is largely complementary to the water collection sump and has over the cover 9 an opening through which water flowing from the surface of the layer 30 can be discharged. In time, the insert body 28 is removed and the ring collar 6 with the sealing web is positioned as prescribed.

15 Skålene 33 og 25 fremstilles ud fra samme udgangsemne. Ved skålen 25 fjernes derved røret 22, og til bunden 2 påsvej-ses studsen 4. På bunden 2's underside er der anbragt opvarmningselementer 17, hvormed det er muligt at fjerne kondensvand i afløbslegemet 1.The bowls 33 and 25 are made from the same starting material. At the bowl 25, the pipe 22 is thereby removed and the bottom 4 is welded to the plug 4. On the underside of the bottom 2 heating elements 17 are placed, by which it is possible to remove condensation water in the drain body 1.
