GulvafløbFloor drains

Opfindelsens områdeFIELD OF THE INVENTION

Den foreliggende opfindelse angår et gulvafløb med en afløbsskål, der har en øvre kant og en afløbsstuds, der er indrettet til forbindelse med et afløbsrør, hvilken afløbsskål omfatter en rist, der danner et demonterbart låg, hvorhos en membranflange er fremstillet integralt med afløbsskålen af et randområde ved afløbsskålens øvre kant.The present invention relates to a floor drain with a drain bowl having an upper edge and a drain connection arranged for connection to a drain pipe, which drain bowl comprises a grate forming a demountable lid, wherein a membrane flange is made integrally with the drain bowl of a edge area at the upper edge of the drain bowl.

Gulvafløbet er af en type, som monteres på sin plads i et gulv med membranflangen placeret i et niveau, som stort set svarer til niveauet på gulvet. Afløbsskålen kan ef-termonteres i et eksisterende gulv eller kan placeres på sin plads før der støbes gulv og være fastholdt under støbningen af gulvet. En bygningsmembran i form af en mambrangulvbelægning fastgøres til membranflangen, fortrinsvis ved at blive fastklemt, fastklæbet eller faststøbt til oversiden heraf. Herefter monteres risten, som kan være placeret i en reces ved afløbsskålens øvre kant. Risten kan valgfrit fastskrues i recessen eller ligge løst heri.The floor drain is of a type which is mounted in its place in a floor with the membrane flange placed at a level which largely corresponds to the level of the floor. The drain bowl can be ef-assembled in an existing floor or can be placed in place before the floor is cast and be held during the casting of the floor. A building membrane in the form of a membrane floor covering is attached to the membrane flange, preferably by being clamped, glued or molded to the upper side thereof. Then mount the grate, which can be placed in a recess at the upper edge of the drain bowl. The grate can optionally be screwed into the recess or lie loose in it.

Opfindelsens baggrundBackground of the Invention

Med henblik på at kunne etablere en vandtæt forbindelse imellem et gulvafløb i eksempelvis et badeværelse eller andet vådrum og en bygningsmembran er det kendt at forsyne afløbsskålen af et gulvafløb med en membranflange, der er beregnet til at forbindes med bygningsmembranen. Det er vigtigt, at der her tilvejebringes en korrekt og tæt forbindelse.In order to be able to establish a watertight connection between a floor drain in, for example, a bathroom or other wet room and a building membrane, it is known to provide the drain bowl of a floor drain with a membrane flange intended to be connected to the building membrane. It is important that a correct and close connection is provided here.

I forbindelse med modernisering eller ombygning i eksempelvis etageejendomme kan det være vanskeligt at anvende gængse gulvafløb med membranflange, fordi det kan være yderst besværligt eller umuligt at opnå den påkrævede tætte forbindelse imellem gulvafløbets membranflange og bygningsmembranen. Derfor kan bygningsmembranen være fastklemt mod membranflangen ved at risten spændes fast til afløbsskålen. Det kræver mange skruer nitter eller lignende for at etablere en ensartet og sikker sammenspændingskraft.In connection with modernization or conversion in, for example, multi-storey buildings, it can be difficult to use common floor drains with membrane flange, because it can be extremely difficult or impossible to achieve the required tight connection between the floor drain membrane flange and the building membrane. Therefore, the building membrane can be clamped against the membrane flange by clamping the grate to the drain bowl. It requires many screw rivets or the like to establish a uniform and safe clamping force.

Mange nitter, skruer eller lignende sammenspændingsorganer har et hoved, der strækker sig til oversiden, så man får et uæstetisk udseende, der kan give ansamling af smuds.Many rivets, screws or similar clamping means have a head that extends to the upper side, so you get an unaesthetic appearance that can cause accumulation of dirt.

Opfindelsens formålObject of the invention

Det er formålet med den foreliggende opfindelse at anvise en fremgangsmåde og et gulvafløb af den indledningsvis nævnte art, og som kan omfatte en membranflange, som på enkel måde kan tilpasses til og forbindes med enten en eksisterende eller en nyetableret bygningsmembran, og hvor man har undgået ovennævnte ulemper.It is the object of the present invention to provide a method and a floor drain of the kind mentioned in the introduction, which may comprise a membrane flange which can be easily adapted to and connected to either an existing or a newly established building membrane, and where one has avoided the above disadvantages.

Beskrivelse af opfindelsenDescription of the invention

Dette opnås ifølge den foreliggende opfindelse med et gulvafløb, der er særpræget ved, at afløbsskålen har et polygonalt tværsnit, for eksempel et trekantet eller rektangulært tværsnit, og fortrinsvis er rendeformet, at membranflangen har et forkrøppet centralt randområde, som omkranser afløbsskålens øvre kant, at der mellem afløbsskålen og risten er tilvejebragt en klemflange i membranflangens forkrøppede centrale randområde, at klemflangen er indrettet til at blive fastspændt mod membranflangen, idet der dannes en spalte derimellem til fastklemning af en ind i afløbsskålen udstrakt bygningsmembran, at risten er anbragt over og dækker klemflangen, idet den strækker sig over hele det forkrøppede centrale randområde, idet der er dannet en rundtgående spalte mellem risten og den ydre afslutning af det forkrøppede centrale randområde til fastklemning af den ind i afløbsskålen udstrakte bygningsmembran.This is achieved according to the present invention with a floor drain, which is characterized in that the drain bowl has a polygonal cross-section, for example a triangular or rectangular cross-section, and is preferably gutter-shaped, that the membrane flange has a crimped central edge area encircling the upper edge of the drain bowl. a clamping flange is provided between the drain bowl and the grate in the crimped central edge area of the membrane flange, that the clamping flange is arranged to be clamped against the membrane flange, a gap being formed therebetween for clamping a building membrane extending into the drain bowl; , extending over the entire crimped central edge area, forming a circumferential gap between the grate and the outer end of the crimped central edge area for clamping the building membrane extending into the drain bowl.

Opfindelsen er speciel ved at være udformet som afløb med lige sidekanter og omfatte trekantede, rektangulære eller andre polygonale tværsnitsformede gulvafløb uanset om de er beregnet til at blive placeret langs en væg eller inde i et rum i afstand fra væg eller hjørne. Her kan siderne være relativt lange hvilket giver særlig behov for fastklemning af bygningsmembranen.The invention is special in that it is designed as a drain with straight side edges and comprises triangular, rectangular or other polygonal cross-sectional floor drains, whether they are intended to be placed along a wall or inside a space at a distance from a wall or corner. Here, the sides can be relatively long, which gives a special need for clamping of the building membrane.

For at opnå en sikker fastklemning af bygningsmembranen mellem membranflangen og klemflangen er der behov for et større antal sammenspændingsorganer, som benyttes til at forbinde membranflangen og klemflangen. Dette vil for eksempel være skru- 3 DK 2008 00020 U3 er. Disse sammenspændingsorganer vil have en del, som er synlig fra klemflangens overside. Dette giver et uæstetisk udseende og giver risiko for synlig smudsansamling i kærve/udsparinger til samvirkning med værktøjer for fastspænding af klemflangen. Med den ovenover anbragte og heldækkende rist skjules de mange sammenspændingsorganer, og risten behøver blot at være fastholdt med en enkelt eller nogle få skruer eller andre sammenspændingsorganer til afløbsskålen. Alternativt kan risten være placeret løst i en reces.In order to obtain a secure clamping of the building membrane between the membrane flange and the clamping flange, a larger number of clamping means are needed, which are used to connect the membrane flange and the clamping flange. This will, for example, be screw- 3 DK 2008 00020 U3 er. These clamping means will have a part which is visible from the upper side of the clamping flange. This gives an unaesthetic appearance and gives the risk of visible dirt accumulation in notches / recesses for cooperation with tools for clamping the clamping flange. With the above-placed and full-covering grate, the many clamping means are hidden, and the grate only needs to be held with a single or a few screws or other clamping means for the drain pan. Alternatively, the grate can be placed loosely in a recess.

Risten vil kunne placeres med sin overside stort set fuldstændig plan med en overside af bygningsmembranen eller den omgivende gulvflade ved en passende dimensionering af gulvafløbets enkeltdele i forhold til tykkelse af bygningsmembranen.The grate can be placed with its upper side almost completely flat with an upper side of the building membrane or the surrounding floor surface by a suitable dimensioning of the individual parts of the floor drain in relation to the thickness of the building membrane.

Ifølge en yderligere udførelsesform er gulvafløbet ifølge opfindelsen særpræget ved, at der i det forkrøppede centrale randområde er tilvejebragt popnitter for fastgørelse af klemflangen og risten til afløbsskålen. Popnitter er meget enkle at montere i afløbsskå-le, der er fremstillet af plade, for eksempel rustfri stålplade. Endvidere kan de være udformet med et gevind, så de er klar til at samvirke med en skrue uden behov for yderligere bearbejdning.According to a further embodiment, the floor drain according to the invention is characterized in that pop rivets are provided in the crimped central edge area for fastening the clamping flange and the grate to the drain bowl. Pop rivets are very simple to mount in drain bowls made of sheet metal, for example stainless steel sheet. Furthermore, they can be designed with a thread so that they are ready to cooperate with a screw without the need for further processing.

Alternativt er gulvafløbet fremstillet med popnitter, der er anvendt til montering af gevindbøsninger. Gevindbøsningeme anvendes til fastskruning af risten og klemflangen med skruer, hvilket er en hensigtsmæssig måde til etablering af montering og demontering, men andre fastgørelsesorganer kan også anvendes, når blot det er muligt at afmontere disse på let måde.Alternatively, the floor drain is made with pop rivets used for mounting threaded bushings. The threaded bushes are used for screwing the grate and the clamping flange with screws, which is a convenient way of establishing assembly and disassembly, but other fastening means can also be used, as long as it is possible to dismantle them easily.

I gulvafløbet vil gevindbøsninger, der er fastgjort til afløbsskålen kunne strække sig ud fra afløbsskålen og derved kunne virke som ankerorganer, der forbinder afløbsskålen med omkringliggende bygningsdele. Når gevindbøsningeme er placeret på ydersiden af afløbsskålen vil de ikke påvirke den indre opbygning. Sådanne gevindbøsninger kan således tjene et dobbelt formål, idet de kan anvendes både til fastgørelse af riste eller andre elementer i afløbsskålen og til ankerorganer.In the floor drain, threaded bushings attached to the drain pan could extend from the drain pan and thereby act as anchoring means connecting the drain pan to surrounding building parts. When the threaded bushings are located on the outside of the drain pan, they will not affect the internal structure. Such threaded bushings can thus serve a dual purpose, as they can be used both for attaching gratings or other elements in the drain pan and to anchor means.

Ifølge en yderligere udførelsesform er gulvafløbet ifølge opfindelsen særpræget ved, at det forkrøppede centrale randområde har en inderst mod afløbsskålens øvre kant beliggende første del, som i brug er vandret, en anden del, der omgiver den første del og som i brug er rettet skråt opefter og udefter væk fra afløbsskålen samt en tredje del, der omgiver den anden del og som i brug er vandret. Dette kan give sikkert fald mod afløbsskålens indre.According to a further embodiment, the floor drain according to the invention is characterized in that the crimped central edge area has a first part located at the inner edge of the drain bowl, which in use is horizontal, a second part which surrounds the first part and which in use is directed obliquely upwards. and outwards away from the drain bowl as well as a third part which surrounds the second part and which in use is horizontal. This can provide a safe slope towards the inside of the drain bowl.

Ifølge en yderligere udførelsesform er gulvafløbet ifølge opfindelsen særpræget ved, at popnitteme er anbragt i den første del af det forkrøppede centrale randområde. Herved kan klemflangen fastspændes med et stort antal skruer tæt ved afløbsskålens øvre kant, således at vand ikke kan trænge ud imellem bygningsmembranen og membranflangen.According to a further embodiment, the floor drain according to the invention is characterized in that the pop rivets are arranged in the first part of the crimped central edge area. Hereby the clamping flange can be clamped with a large number of screws close to the upper edge of the drain bowl, so that water cannot penetrate between the building membrane and the membrane flange.

Der kan være tilvejebragt popnitter i enderne af den første del af det centrale randområde for fastgørelse af risten. Herved vil skruer eller lignende ikke strække sig gennem klemflangen, men kan i stedet være tilvejebragt uden for klemflangens ydre randområde.Pop rivets may be provided at the ends of the first portion of the central edge area for attachment of the grate. Hereby screws or the like will not extend through the clamping flange, but may instead be provided outside the outer edge area of the clamping flange.

Ifølge en yderligere udførelsesform er gulvafløbet ifølge opfindelsen særpræget ved, at det er forsynet med aflange åbninger i risten og/eller klemflangen for justerbar modtagelse af fastspændingsorganer, fortrinsvis skruer til montering i samvirkende organer, fortrinsvis gevindbøsninger i gulvafløbet.According to a further embodiment, the floor drain according to the invention is characterized in that it is provided with elongate openings in the grate and / or the clamping flange for adjustable receiving of clamping means, preferably screws for mounting in cooperating means, preferably threaded bushings in the floor drain.

Således kan klemflagen og/eller risten omfatte aflange åbninger til modtagelse af skruer for fastgørelse til afløbsskålen. Herved bliver det muligt at foretage en justering af gulvafløbets klemflange og/eller rist i forhold til afløbsskålen. Det bliver således muligt på sikker måde at positionere afløbet, så der kommer korrekt fald for afløbet, og således at det placeres korrekt i forhold til det omgivende gulv, hvori det er monteret.Thus, the clamping flag and / or the grate may comprise elongate openings for receiving screws for attachment to the drain bowl. This makes it possible to make an adjustment of the floor flange's clamping flange and / or grate in relation to the drain bowl. It thus becomes possible to position the drain in a safe manner so that there is a correct slope for the drain and so that it is placed correctly in relation to the surrounding floor in which it is mounted.

Ifølge en yderligere udførelsesform er gulvafløbet ifølge opfindelsen særpræget ved, at det er fremstillet af rustfrit stål. Dette er egnet til brug i forskellige typer gulve og til forskellige anvendelsesområder såvel inden for industri og husholdning. Det kan være fremstillet af en plade. Et sådan gulvafløb er meget enkelt af fremstille. Det kan ske 5 DK 2008 00020 U3 ved standsning, bukning af plader og med udstansning af nødvendige huller for modtagelse af skruer, nitter eller lignende.According to a further embodiment, the floor drain according to the invention is characterized in that it is made of stainless steel. This is suitable for use in different types of floors and for different applications in both industry and household. It can be made of a plate. Such a floor drain is very simple to manufacture. This can be done by stopping, bending the plates and by punching out the necessary holes for receiving screws, rivets or the like.

Ifølge en yderligere udførelsesform er gulvafløbet ifølge opfindelsen særpræget ved, at det omfatter en afløbsskål i form at en aflang afløbsrende med en langside mellem 500 og 1200 mm og en bredde mellem 90 og 120 mm, at der er anvendt mellem 5 og 12 skruer i hver side, at disse skruer samvirker med gevindforsynede popnitter i gulvaflø-bets membranflange, og at risten i hver ende af renden er fastholdt af en skrue, der ligeledes samvirker med gevindforsynede popnitter i gulvafløbets membranflange. Således vil afstand mellem skruerne være mellem 90 og 100 mm, således at der opnås en sikker sammenspænding. I praksis kan afløbsrenden være fremstillet med diskrete længder for eksempel 700, 800,900 og lOOOmm.According to a further embodiment, the floor drain according to the invention is characterized in that it comprises a drain bowl in the form of an elongate drain gutter with a long side between 500 and 1200 mm and a width between 90 and 120 mm, that between 5 and 12 screws are used in each that these screws cooperate with threaded pop rivets in the membrane flange of the floor drain, and that the grate at each end of the gutter is held by a screw which also cooperates with threaded pop rivets in the membrane flange of the floor drain. Thus, the distance between the screws will be between 90 and 100 mm, so that a secure clamping is achieved. In practice, the drain gutter can be made with discrete lengths, for example 700, 800,900 and 100 mm.
