Opfindelsen vedrører en afløbsindsats til montering i eksisterende afløbsskåle af standardtype med henblik på etablering af tæthed mellem gulv og afløbssystem efter forudgående overskæring af det eksisterende lodrette afløbsror.The invention relates to a drainage insert for mounting in existing standard drainage bowls for the purpose of establishing floor-to-drain tightness after prior cutting of the existing vertical drain pipe.
5 Ved renovering af eksisterende afløbssystemer udført i støbejern har det vist sig fordelagtigt at udnytte de fastmu-rede eller faststøbte støbejernsrørstykker, som efter overskæring over og under en etageadskillelse bliver tilbage, til brug som rørgennemføringer til nye rør, som derved får en no-10 get ringere lysning. Dette gælder både for faldstammer og for afløb. Fordelene ligger væsentligst i de begrænsede bygningsskader i forbindelse med overskæring i stedet for udhugning af de eksisterende dele.5 When renovating existing drainage systems made of cast iron, it has proved advantageous to utilize the walled or cast cast iron pipe pieces which, after being cut above and below a floor separation, remain for use as pipe pipes for new pipes, thereby obtaining a no-10 get poorer illumination. This is true for both fall and drainage. The benefits are mainly in the limited building damage associated with cutting rather than cutting out the existing parts.
Eksisterende gulvafløb har et lodret rør, som er forbun-15 det med en P-formet vandlås, og afskæringen af disse afløbsror sker lige over vandlåsen. Derved fremkommer et ret rørstykke af støbejern, som foroven udvider sig til den eksisterende afløbsskål, som afsluttes i gulvplan, idet den typisk er indstøbt i en terrazzogulvbelægning og forsynet med en 20 rist. Det er ikke formålstjenligt at fortsætte med at benytte en støbejernsafløbsskål i forbindelse med en renovering, og løsninger, som baserer sig på f.eks. afløbsindsatse af kunststof, som ved hjælp af gummiprofiler etablerer en læbetætning mod den eksisterende skål, vil ikke være velegnede. Disse 25 konstruktioner vil ikke være langtidsholdbare, og enhver utæthed mellem afløbsskål og indsats vil vise sig ved vanddryp i den underliggende etage. Tilsvarende vil en utæthed mellem en indsats og et nystøbt gulv medføre indtrængende fugt i etageadskillelsen. Den ringe holdbarhed skyldes blandt 3 0 andet, at kunststof er udsat for krybning og at bløde gummi-profiler ældes relativt hurtigt.Existing floor drains have a vertical pipe connected to a P-shaped water trap and the cut-off of these drainage pipes takes place just above the water trap. This results in a straight piece of cast iron, which extends above to the existing drain bowl, which is finished in floor plan, typically embedded in a terrazzo floor covering and provided with a grate. It is not advisable to continue using a cast iron drain bowl in connection with a renovation, and solutions based on e.g. plastic drain inserts which, using rubber profiles, establish a lip seal against the existing bowl, will not be suitable. These 25 structures will not be long-lasting, and any leakage between drain bowl and insert will be evident by water dripping in the underlying floor. Similarly, a leak between an insert and a newly-molded floor will result in penetrating moisture in the floor separation. The poor durability is due, among other things, to the fact that plastic is subject to creep and that soft rubber profiles age relatively quickly.
Med henblik på at etablere tæthed for et afløb fra en tagflade, som bliver renoveret ved pålægning af ekstra isolation og ny belægning er det fra tysk patentskrift DE 34 25 35 654 kendt at etablere tætning til en eksisterende afløbsskål i en stort set vandret tagflade ved at fastskrue en tætnings-plade med en diameter meget større end afløbsskålen med pak-' ning mod tagfladen og ved derefter at indføre røret fra en 2 DK 172804 B1 j afløbsindsats med en tragtformet øvre del med en udragende flange og et lige rør i forlængelse af tragtens snævre del i en ringformet pakning, som er lejret i en central cylinderformet åbning i tætningspladen. Denne kendte måde at opnå en 5 tætning på er almindeligvis uegnet til f.eks. et badeværelsesgulv.In order to establish the density of a drain from a roof surface which is being renovated by the application of extra insulation and new coating, it is known from German patent specification DE 34 25 35 654 to seal to an existing drain bowl in a substantially horizontal roof surface by screw a sealing plate with a diameter much larger than the drain bowl with gasket to the roof surface and then insert the pipe from a drain insert with a funnel-shaped upper part with a protruding flange and a straight tube in extension of the funnel. narrow portion of an annular gasket which is housed in a central cylindrical opening in the sealing plate. This known way of obtaining a seal is generally unsuitable for e.g. a bathroom floor.
Det er opfindelsens formål at anvise en afløbsindsats, hvor de nævnte ulemper i forbindelse med gulvafløbsskåle er ophævet, og dette opnås ifølge opfindelsen ved, at indsatsen 10 er udført som angivet i den kendetegnende del af krav 1. Det er herved muligt at opnå en god tætning på sikker og holdbar måde.SUMMARY OF THE INVENTION It is an object of the invention to provide a drainage insert in which said disadvantages in connection with floor drain bowls are achieved and this is achieved according to the invention in that the insert 10 is designed as defined in the characterizing part of claim 1. It is hereby possible to obtain a good seal in a safe and durable manner.
I krav 2 er anvist en udførelsesform, som er velegnet til brug i en eksisterende afløbsskål, hvor den eksisterende 15 gulvbelægning lades uberørt, og hvor tætningen mod denne foregår ved indsatsens flange.Claim 2 discloses an embodiment which is suitable for use in an existing drain bowl where the existing floor covering is left untouched and where the sealing against it takes place by the insert flange.
I krav 3 er anvist en udførelsesform, som er særlig velegnet, hvor der f.eks. skal lægges klinker ovenpå den eksisterende gulvbelægning, og hvor et afløb skal være i det væ-20 sentlige i plan hermed.In claim 3 there is provided an embodiment which is particularly suitable where, e.g. must be laid on the existing flooring and where a drain must be substantially in plan.
I krav 4 er anvist en konstruktionsdetaille, som effektiviserer monteringsarbejdet og formindsker indflydelsen af partikelformede urenheder.Claim 4 discloses a structural detail which streamlines the mounting work and reduces the influence of particulate impurities.
I krav 5 er anvist et element, som kan indlægges i en ek-25 sisterende afløbsskål, dersom de sædvanligvis forekommende knaster er skæve eller tæret bort.Claim 5 discloses an element which can be inserted into an existing drain bowl if the usually present bumps are skewed or worn away.
Opfindelsen vil i det følgende blive beskrevet nærmere j under henvisning til tegningen, hvorThe invention will now be described in more detail with reference to the accompanying drawings, in which

Fig. 3 viser en understøtning for underlagsringen ifølge 35 krav 6.FIG. 3 shows a support for the support ring according to claim 6.
På Fig. 1 ses en eksisterende afløbsskål 1 af standardty-pe, som er indstøbt i et betongulv 2 med et terrazzo-slidlag 3. Afløbsroret 4 er overskåret i det væsentlige i ret vinkel li ! m 3 DK 172804 B1 et passende stykke under loftet i den underliggende etage, vist ved C. I den eksisterende afløbsskål er anbragt en underlagsring 5 af rustfast stål, som hviler på de typisk fire knopper 6, som har typisk to gevindhuller til fastskruning af 5 den tidligere afløbsrist. Disse knopper tjener her alene til at styre underlagsringen 5. Ovenpå underlagsringen 5 er anbragt en ringformet pakning i form af en o-ring 7, som er således dimensioneret i overensstemmelse med de alment kendte regler for denne standardkomponent, at den efterfølgende kom-10 pression sikrer både tæthed og den fornødne elasticitet. Indsatsen består af en flange 8, som har en forsætning 9, af en tragtformet del 10 og af et rør 11. Alle dele er udført i rustfast stål. Den nederste del af røret 11 er forsynet med gevind 12, hvorpå er skruet en omløber 13 med en flade 14, 15 som er egnet til anlæg mod den overskåme ende af afløbsroret 4. Omløberen 13 er modsat fladen 14 forsynet med en spidsende 5, som svarer til det ved renoveringen benyttede rørsystem.In FIG. 1, an existing standard type drainage bowl 1 is embedded in a concrete floor 2 with a terrazzo abrasion layer 3. The drainage pipe 4 is cut substantially at right angles 1 to 1. m 3 DK 172804 B1 a suitable piece below the ceiling in the underlying floor, shown at C. In the existing drain bowl is a stainless steel support ring 5, which rests on the typically four knobs 6, which typically have two threaded holes for screwing 5 the former drain grate. Here, these knobs serve solely to control the support ring 5. On top of the support ring 5 is arranged an annular gasket in the form of an o-ring 7, which is so dimensioned in accordance with the generally known rules for this standard component that the subsequent compression ensures both tightness and elasticity. The insert consists of a flange 8, which has an offset 9, of a funnel-shaped part 10 and of a pipe 11. All parts are made of stainless steel. The lower part of the pipe 11 is provided with a thread 12, on which is screwed an encoder 13 with a surface 14, 15 which is suitable for abutment towards the oversized end of the drain pipe 4. The encoder 13 is opposite to the surface 14 provided with a pointed end 5 which corresponds to the pipe system used in the renovation.
Efter anbringelsen af afløbsindsatsen i den eksisterende af-løbsskål ovenpå o-ringen 7, skrues omløberen 13 på, og den 20 strammes, indtil flangen 8 rører ved underlagsringen 5. Dette viser sig ved stærkt forøget modstand mod videre drejning af omløberen. Dimensioneringen af o-ringen bevirker, at den presses ud af mellemrummet mellem forsætningen 9 og underlagsringen med en sådan afpasset kraft, at den danner tætning 25 direkte mod den eksisterende afløbsskål. Det falder indenfor fagmandens område at benytte eksisterende dimensioneringstabeller således, at den fornødne kompression og elasticitet for den pågældende kunstgummisort opnås med de givne dimensioner for de elementer 8,9,5 samt 1, som afgrænser o-ringen.After placing the drain insert in the existing drain bowl on top of the o-ring 7, the encoder 13 is screwed on and the 20 is tightened until the flange 8 touches the support ring 5. This is shown by greatly increased resistance to further rotation of the encoder. The dimensioning of the o-ring causes it to be pushed out of the space between the recess 9 and the support ring with such an adapted force that it forms a seal 25 directly against the existing drain bowl. It is within the skill of the art to utilize existing sizing tables such that the required compression and elasticity of the particular rubber type concerned are obtained with the given dimensions for the elements 8,9,5 and 1 defining the o-ring.
30 Imidlertid kan man meget vel forestille sig, at andre tværsnit end en cirkel kan udnyttes for en komprimeret ringformet pakning anbragt på dette sted, og hertil svarer andre, kendte dimensioneringstabeller. Derved behøver installatøren overhovedet ikke bekymre sig om disse tekniske forhold, men blot 35 spænde omløberen indtil modstand mærkes.30 However, it is quite conceivable that cross sections other than a circle can be utilized for a compressed annular gasket disposed at this location, to which other known sizing tables correspond. Thereby, the installer does not have to worry about these technical conditions at all, but only 35 clamp the bypass until resistance is felt.
På Fig. 2 er tilsvarende vist en eksisterende afløbsskål 1 af standardtype, som er indstøbt i et betongulv 2 med et *- terrazzo-slidlag 3, ovenpå hvilket det ønskes at støbe et af- 4 DK 172804 B1 retningslag W med efterfølgende lægning af fliser T. Afløbsrøret 4 er som i Fig. 1 overskåret i det væsentlige i ret vinkel et passende stykke under loftet i den underliggende etage, vist ved C. Indsatsen består af en flange 8, af en 5 tragtformet del 10a og af et rør 11. Den tragtformede del 10a er en del fladere end i udførelsesformen vist på Fig. 1, og idet flangen 8 bliver hævet op over den eksisterende afløbs-skål svarende til den ny gulvbelægnings tykkelse, vil røret 11 for en given længde af det eksisterende afløbsror 4 være 10 længere end ved det foregående eksempel. Alle dele er udført i rustfast stål. Den nederste del af røret 11 er forsynet med gevind 12, hvorpå er skruet en omløber 13 med en flade 14, som er egnet til anlæg mod den overskårne ende af afløbsroret 4. Omløberen 13 er modsat fladen 14 forsynet med en spidsende 15 S, som svarer til det ved renoveringen benyttede rorsystem.In FIG. 2 is similarly shown an existing standard type drain bowl 1, which is embedded in a concrete floor 2 with a * - terrazzo abrasion layer 3, on top of which it is desired to mold a drainage layer W with subsequent laying of tiles T. The drain pipe 4 is as in FIG. 1, substantially at a right angle, a suitable section is cut below the ceiling of the underlying floor, shown at C. The insert consists of a flange 8, a 5 funnel-shaped part 10a and a pipe 11. The funnel-shaped part 10a is a bit flatter than in the embodiment shown in FIG. 1, and as the flange 8 is raised above the existing drain bowl corresponding to the thickness of the new floor covering, the pipe 11 for a given length of the existing drain pipe 4 will be 10 longer than in the previous example. All parts are made of stainless steel. The lower part of the pipe 11 is provided with a thread 12, on which is screwed an encoder 13 with a surface 14 suitable for abutting against the cut end of the drain pipe 4. The encoder 13 is opposite to the surface 14 provided with a pointed end 15 S, which corresponds to the rudder system used in the renovation.
Gevindet 12 er ført tæt op mod bunden af tragten 10a, og en kontramøtrik 15 er skruet netop så højt op, at flangen 8 kommer i plan med den ny gulvbelægning T, når en mellem kontramøtrikken 15 og indersiden af afløbsskålen 1 beliggende 20 ringformet pakning er komprimeret. Efter anbringelsen af af-løbsindsatsen 1 med kontramøtrik 15 og ringformet pakning 16 i den eksisterende afløbsskål, foretages justering af kontramøtrikkens placering indtil højden af indsatsen passer med den ønskede gulvbelægning T. Herefter påsættes omløberen 13 25 nedefra, og den spændes, indtil der mødes modstand, og den ringformede pakning er tæt. Denne tæthed opnås ved rutinemæssig design af komprimeringsgrad og gummikvalitet, så der opnås lang holdbarhed af tætningen. Den ringformede pakning 16 kan være vulkaniseret fast på kontramøtrikken 15. Omkring og 30 over flangen 8, hvis højde er justeret, faststøbes en karm F som afslutning. Ved brug af større klinker vil det være mest hensigtsmæssigt at benytte et kvadratisk nyt afløb, hvorfor karmen F og flangen 8, samt tragten 10a har en kvadratisk afslutning foroven.The thread 12 is brought close to the bottom of the hopper 10a, and a counter nut 15 is screwed up just so high that the flange 8 is flush with the new floor covering T when an annular gasket located between the check nut 15 and the inside of the drain bowl 1 is compressed. After placing the drain insert 1 with counter nut 15 and annular gasket 16 in the existing drain bowl, adjust the position of the counter nut until the height of the insert matches with the desired floor covering T. Then the nut 13 is applied from below and it is tightened until resistance meets , and the annular gasket is sealed. This density is achieved by routine design of compression grade and rubber quality to achieve long durability of the seal. The annular gasket 16 may be vulcanized firmly on the check nut 15. Around and 30 above the flange 8, the height of which is adjusted, a frame F is molded to the end. When using larger clinker it would be most appropriate to use a square new drain, therefore the frame F and the flange 8, as well as the funnel 10a have a square end at the top.
35 Konstruktionen ifølge krav 3, som er benyttet i ovenstå ende eksempel, kan udmærket benyttes, hvor der tidligere har været etableret en ny støbt gulvbelægning ovenpå den gamle, med f.eks. en primitiv brønd gennem betonen ned til det eksi- i !j 5 DK 172804 B1 sterende gulvafløb. En sådan primitiv afløbsforbindelse giver stor risiko for vandindtrængen i etageadskillelsen eller mellem det udstøbte lag og den gamle gulvbelægning i de tilfælde, hvor vandlåsen er tilstoppet, og der kommer et statisk 5 vandtryk på væggen i den primitive brønd. Ved renovering under brug af indsatse ifølge opfindelsen er det blot nødvendigt at bortmejsle den eksisterende højtliggende karm, at justere kontramøtrikken 15 med den ringformede pakning 16, indtil indsatsens flange ligger i det allerede eksisterende plan 10 for gulvbelægningen, og at fortsætte monteringen som ovenfor beskrevet. Der afsluttes med støbning.The structure of claim 3, which is used in the above end example, can be very well used where a new cast floor covering has been previously established on top of the old one, e.g. a primitive well through the concrete down to the ex- isting floor drain. Such a primitive drainage connection poses a great risk of water penetration into the floor separation or between the cast layer and the old floor covering in cases where the water trap is clogged and a static water pressure comes on the wall of the primitive well. When renovating using inserts according to the invention, it is only necessary to chisel the existing high-lying frame, adjust the counter nut 15 with the annular gasket 16 until the flange of the insert lies in the already existing plane 10 for the floor covering, and to continue the installation as described above. Finishing with casting.
På Fig. 3 er vist en understøtning for underlagsringen 5, som benyttes i de tilfælde, hvor de i den eksisterende skål faststøbte knopper ikke er velegnede til at understøtte rin-15 gen 5. Ved skæv understøtning er der fare for, at den kæntrer i skålen 1, hvorved den ringformede pakning 7 ikke bliver tæt ved tilspænding. Understøtningen består af fire tårne 6a af rustfri stålplade, som er svejst til en ring 17 af mindre diameter end underlagsringen 5. Denne er det første, som læg-20 ges ned i afløbsskålen 1. Ringen 17 har udsparinger, som svarer til placeringen af de defekte knopper, og tårnene 6a kommer da til at ligge mellem knopperne 6 og med en højde, som er beregnet på at få en korrekt funktion af den ringformede pakning. Denne højde vil ganske nøje svare til de oprindelige 25 knopper, som normalt har en veldefineret højde, idet de oprindeligt tjente som understøtning af en rist af veldefineret tykkelse.In FIG. 3, there is shown a support for the backing ring 5 which is used in cases where the knobs embedded in the existing bowl are not suitable for supporting ring 5. In skewed support, there is a danger that it will taper in the bowl 1, whereby the annular seal 7 does not become tight by tightening. The support consists of four stainless steel towers 6a welded to a ring 17 of smaller diameter than the backing ring 5. This is the first to be laid 20 in the drain bowl 1. The ring 17 has recesses corresponding to the position of the defective knobs, and the towers 6a will then lie between the knobs 6 and at a height intended to have a proper function of the annular gasket. This height will exactly match the original 25 knobs, which usually have a well-defined height, initially serving as a support for a well-defined thickness grid.
