Description

Oppfinnelsen vedrører et varmeelement, særlig som golv eller golvelement, hvilket er nærmere angitt i innledningen til patentkrav 1. Oppfinnelsen vedrører videre en framgangsmåte for framstilling av et varmeelement i samsvar med krav 1. The invention relates to a heating element, in particular as a floor or floor element, which is specified in more detail in the introduction to patent claim 1. The invention further relates to a method for producing a heating element in accordance with claim 1.

Det anses som fordelaktig å anordne såkalte varmesløyfer i golv. Til dette bruk har en hittil oftest lagt fram- og tilbakegående metallrør i betonggolv, som støpes rundt metallrørene som fungerer som varmesløyfer. Denne teknikk er beheftet med flere ulemper. En er i praksis nærmest bundet til betonggolv, og tvinges dermed til å støpe golvet rundt sløyfene. Oppstår lekkasje eller andie feil, må golvet helt eller delvis rives opp, noe som er forbundet med store kostnader og problemer. Videre må slike sløyfer varme opp hele golvet, d.v.s. en svært stor masse hvis temperaturøkning og også-senkning tar lang tid. Fordelaktig temperaturregulering i løpet av korte tidsperiodtr er her helt utelukket. It is considered advantageous to arrange so-called heating loops in the floor. For this purpose, one has so far most often laid back and forth metal pipes in concrete floors, which are cast around the metal pipes that act as heating loops. This technique is subject to several disadvantages. In practice, one is almost tied to a concrete floor, and is thus forced to mold the floor around the loops. If a leak or other fault occurs, the floor must be completely or partially torn up, which is associated with large costs and problems. Furthermore, such loops must heat the entire floor, i.e. a very large mass whose temperature increase and also decrease take a long time. Advantageous temperature regulation during short periods of time is completely excluded here.

Hensikten med den foreliggende oppfinnelsen er for det første å fjerne ovennevnte ulemper og frambringe . et nytt varmeelement, særlig som golv eller golvelement, som lett, raskt og enkelt og på en kostnadssparende måte kan plasseres på vilkårlig underlag på en måte at et slikt varmeelement uten problemer også kan framstilles av lekmenn. The purpose of the present invention is, firstly, to remove the above-mentioned disadvantages and to produce . a new heating element, in particular as a floor or floor element, which can be easily, quickly and simply and in a cost-saving manner placed on any surface in such a way that such a heating element can also be produced by laymen without problems.

Disse og andre formål oppnås ifølge foreliggende oppfinnelse, ved at et varmeelement avjtyper omtalt inn-ledningsvis, i hovedsak er utstyrt som angitt i den karak-teriserende delen av patentkrav 1 hhv. ved at framgangs-måten for framstilling av et slikt varmeelement utføres som angitt i underkravene. These and other purposes are achieved according to the present invention, in that a heating element of the type mentioned in the introduction is essentially equipped as indicated in the characterizing part of patent claim 1 or in that the procedure for producing such a heating element is carried out as specified in the sub-claims.

Ytterligere trekk og fordeler ved oppfinnelsen framgår av følgende detaljbeskrivelse under henvisning ti<.>'Nedlagte tegninger. På disse viser: Fig. 1 et perspektivriss av hjørnedelen av en foretrukket utførelsesform av et varmeelement ifølge oppfinnelsen, Further features and advantages of the invention appear from the following detailed description with reference to the enclosed drawings. These show: Fig. 1 a perspective view of the corner part of a preferred embodiment of a heating element according to the invention,

fig. 3 elementet i samsvar med fig. 2 i bruksstilling etter sammen-montering. fig. 3 the element in accordance with fig. 2 in use position after assembly.

På tegningene betegner 1 en bunnplate som fortrinnsvis består av ektrudert plast,, som kan framstilles i ønskete standardbredder. Denne bunnplate er utstyrt med innbyrdes, fortrinnsvis parallelle spor 2 hvis dybde 15 eksempelvis kan være opptil ca. 2/3 av platens tykkelse. Sporprofilen er fortrinnsvis slik at sporveggene 3 i det minste opptil sporenes inngangsside divergerer mot sporbunnen 4. I det viste utførelseseksempelet har sporene en trapes- eller svalehale formet profil, idet sporveggene 3 ved den åpne spors iden og ved bunnen 4 er jevnt rundet eller faset, slik at en oppnår omtrentlig Z- eller S-formct utførelsesform. In the drawings, 1 denotes a bottom plate which preferably consists of extruded plastic, which can be produced in the desired standard widths. This bottom plate is equipped with mutually, preferably parallel grooves 2 whose depth 15 can for example be up to approx. 2/3 of the plate's thickness. The track profile is preferably such that the track walls 3 at least up to the entrance side of the tracks diverge towards the track bottom 4. In the embodiment shown, the tracks have a trapezoidal or dovetail-shaped profile, the track walls 3 at the open track side and at the bottom 4 being evenly rounded or chamfered, so that an approximate Z- or S-shaped embodiment is obtained.

I sporene 2 plasseres varmerør 6 av i og for sog kjent type, og på i og for seg kjent måte, d.v.s. det kan dreie seg om plast- eller metallrør, eventuelt plastmant-lete metallrør, hvor plasten kan være polyeten HD med en ytterdiameter på 8 mm, og en inndrdiameter på 6mm, og hvor. sløyfene løper enten fram og tilbake gjennom et varmeelement eller et helt golv, eller hvor i og for seg kjente fordelere er plassert på ønskete steder, siik at varmemediet i nærliggende rør kan strømme til samme hull og medføre mindre trykktap, og en raskere og jevnere oppvarming hhv. temperatursenkning, der en ønsker det. Varme-rørene kan ha vilkårlig profil, men i praksis kommer ute-. lukkende sirkelrund prpfil i betraktning og med diameter som i samsvar med en foretrukket utførelsesform er noe større enn sporhalsens vidde 16, hvilket medfører en viss sneppertvirkning, idet varmerørene og/eller bunnplaten ved rørenes iegging elastisk deformeres hoe, og det skjer en mindre ekspansjon i.det videre indre av sporet slik at rørene holdes igjen i sporene uten særskilte hjelpemidler. In the grooves 2, heating pipes 6 of a known type are placed, and in a known manner, i.e. it can be plastic or metal pipes, possibly plastic-sheathed metal pipes, where the plastic can be polyethylene HD with an outer diameter of 8 mm, and an inner diameter of 6 mm, and where. the loops either run back and forth through a heating element or an entire floor, or where known distributors are placed in the desired places, so that the heating medium in nearby pipes can flow to the same hole and cause less pressure loss, and faster and more even heating respectively temperature reduction, where desired. The heating pipes can have any profile, but in practice the outside closed circular prpfile in consideration and with a diameter which, in accordance with a preferred embodiment, is somewhat larger than the width of the groove neck 16, which entails a certain snapping effect, as the heating pipes and/or the bottom plate are elastically deformed when the pipes are laid, and a minor expansion takes place i. the further inside of the track so that the pipes are kept in the tracks without special aids.

Som det framgår av fig. 2, er decilagte rørene skjøvet noe fram over platens 1 overside som dannes av åsene 5 mellom sporene 2, og dette medfører at en pålagt dekkplate 7 nærmest kommer til å hvile på rørene 6, som tilsvarer en avstand 12 mellom dekkplatens underside og bunnplatens overside. Dekkplaten eller -platene . har for-ankringsplugger 8 og/eller forankringsskruer 9, som inn-føres i plugghull 13 hhv. skruehull 14 i bunnplaten 1, og en slik forbindelse skal dras til og redusere eller fortrinnsvis planere ut avstanden 12 i samsvar med fig. 3. Brukes det plugger så er disse fortrinnsvis fast forenet med dekkplaten 7 og har på sin skaftdel riflinger eller andre i og for seg kjente låseorganer, som motsvares av riflete hullvegger slik at trykkpåføringen på tetnings-platen innenfor området for pluggene medfører at disse automatisk trenger inn i hull og holder ' dekkplaten i den nedpressete stillingen. As can be seen from fig. 2, the decilaged pipes are pushed somewhat forward over the upper side of the plate 1 which is formed by the ridges 5 between the grooves 2, and this means that an applied cover plate 7 almost rests on the pipes 6, which corresponds to a distance 12 between the underside of the cover plate and the upper side of the bottom plate. The cover plate or plates. has anchoring plugs 8 and/or anchoring screws 9, which are inserted into plug holes 13 or screw hole 14 in the bottom plate 1, and such a connection must be drawn to and reduce or preferably level out the distance 12 in accordance with fig. 3. If plugs are used, these are preferably firmly united with the cover plate 7 and have on their shaft part knurling or other per se known locking means, which correspond to knurled hole walls so that the application of pressure on the sealing plate within the area of the plugs results in these automatically needing into the hole and holds the cover plate in the depressed position.

I samsvar med en foretrukket utførelsesform er varmerørene 6 og/eller bunnplaten 1 utført i deformerbart materiale slik at rør med sirkelrund profil eksempelvis i ubelastet tilstand deformeres til formpasning i trapes-formige spor, slik som det framgår av fig.3. Slik fyller rørene ut sporene, og en oppnår istedenfor linjekontakt med . dekkplaten en betydelig overflatekontakt og slik utmerket og omfattende.varmeoverføring mellom rør og dekkplate. In accordance with a preferred embodiment, the heating pipes 6 and/or the bottom plate 1 are made of deformable material so that pipes with a circular profile, for example in an unloaded state, are deformed to form fit in trapezoidal grooves, as can be seen from fig.3. In this way, the pipes fill in the grooves, and you instead achieve line contact with . the cover plate a significant surface contact and such excellent and comprehensive.heat transfer between tube and cover plate.

Nevnte varmeoverføring og/eller låsing av rør-ene i sporene kan økes ved at det i sporene innføres en fyllmasse 10, som er flytende eller halvflytende, eventuelt først stiv e^ler fast og etter oppvarming flyt-, ende eller halvflytende, slik at det i mellomstadiet ifølge fig. 2 skjer en fortrengning til sidene av fyllmassen, son i endestadiet presses opp for å utfylle eventuelle gjenværende hull direkte under dekkplaten 7. Fyllmassen lo kan være et lim og/eller annen masse med fordelaktig varmeled ningstall. Selvsagt er det også mulig å innføre slik fyllmasse etter at rørene er bragt på plass i folden mellom disse og sporhalsen. Er massen et lim, kan dette eventuelt skape en holdbar forbindelse mellom dekkplaten og rørene og/eller bunnplaten. Said heat transfer and/or locking of the tubes in the grooves can be increased by introducing a filling material 10 into the grooves, which is liquid or semi-liquid, possibly first rigid or solid and after heating liquid, final or semi-liquid, so that in the intermediate stage according to fig. 2, a displacement occurs to the sides of the filling mass, so in the final stage it is pushed up to fill any remaining holes directly under the cover plate 7. The filling mass can be an adhesive and/or other mass with an advantageous thermal conductivity. Of course, it is also possible to introduce such filler after the pipes have been brought into place in the fold between them and the track neck. If the mass is an adhesive, this can possibly create a durable connection between the cover plate and the pipes and/or the base plate.

Deformasjon av rørene og/eller bunnplaten og påvirkningen av fyllmassen kan eventuelt fremmes ved at er i mellomstadiet ifølge fig.2 lar varmt eller kraftig opphetet vann passere gjennom rørene, slik at rørmaterialet og/eller bunnplatens materiale mykner, og på kort tid og på enkel måte fås en enkel formpasning i samsvar med fig.2. Sendes sterkt opphetet vann gjennom rørene, kan eventuelt et dekkplatemateriale være aktuelt, særlig ved laminerte dekkplater, som mykner og da opptar en del av varmerørene, som slik innhylles noe i dekningsplaten. Deformation of the pipes and/or the bottom plate and the influence of the filling compound can possibly be promoted by allowing warm or strongly heated water to pass through the pipes, so that the pipe material and/or the material of the bottom plate softens, and in a short time and in an easy way, a simple fit is obtained in accordance with fig.2. If strongly heated water is sent through the pipes, a cover plate material may be relevant, especially in the case of laminated cover plates, which softens and then takes up part of the heating pipes, which are thus somewhat enveloped in the cover plate.

Hele oversiden av bunnplaten 1 inklusiv sporveggene og -bunnene og/eller bunnplatens underside kan eventuelt utstyres med et varmereflekterende sjikt,<f>leks.' ved eloksering. Videre kan fyllmassen påføres over bunnplatens overflate for å utfylla eventuelle ytterligere ujevnheter og/eller virke som lim for hele undersiden av dekkplaten. The entire upper side of the bottom plate 1 including the track walls and bottoms and/or the underside of the bottom plate can optionally be equipped with a heat-reflecting layer, e.g. by anodizing. Furthermore, the filler can be applied over the surface of the base plate to fill in any further irregularities and/or act as glue for the entire underside of the cover plate.

Som nevnt kan dekkplaten bestå av et laminat, der minst et øvre sjikt er formstabilt i,og for å oppnå,et plant golv. Dekkplaten kan bestå av metall og/eller plast og/eller annet materiale, og den og/eller bunnplaten skal ha en oppstivende funksjon slik at varmeelementet ifølge oppfinnelsen kan plasseres på vilkårlig underlag. Under bunnplaten er det fortrinnsvis plassert en f.eks. påklis-tret isoleringsskive 11 av i og for seg kjent utførelse. As mentioned, the cover plate can consist of a laminate, where at least one upper layer is dimensionally stable in order to achieve a flat floor. The cover plate can consist of metal and/or plastic and/or other material, and it and/or the bottom plate must have a stiffening function so that the heating element according to the invention can be placed on any surface. Under the base plate, there is preferably placed an e.g. glued-on insulating disc 11 of a design known per se.

Varmerørene kan som nevnt legges som er ende-løst rør eller en kan ved modulsystem plassere passende koblinger mellom nærliggende élemerit. Videre er det mulig å levere helt eller delvis ferdige varmeelement, i det siste tilfellet f. eks. i varmerør lagt i sporene 2. Varme-' rørene kan alternativt leveres festet på dekkplatens underside. As mentioned, the heating pipes can be laid as end-to-end pipes or, with a modular system, suitable connections can be placed between nearby elements. Furthermore, it is possible to deliver completely or partially finished heating elements, in the latter case, e.g. in heating pipes laid in the grooves 2. Alternatively, the heating pipes can be delivered fixed on the underside of the cover plate.

I samtlige tilfeller oppnås lave oppvarmete masser, som medfører at betydelig:, temperaturforhøyelse hhv. -senkning kan skje på kortest tenkbar tid. Underlaget kan være vilkårlig og et betonggolv kan nå støpes raskt oj; In all cases, low heated masses are achieved, which means that a significant increase in temperature or -lowering can take place in the shortest possible time. The substrate can be arbitrary and a concrete floor can now be cast quickly oj;

enkelt og uten å ta hensyn til anstrengende manuell legg-ing av varmerør i samsvar med et alt for individuelt mønster i hvert enkelt tilfelle. Videre kan byggehøyden holdes svært lav og slike varmeelement kan med fordel pias - seres også i eldre hus på eksisterende golv. Selvsagt til-passes varmeelementehe ifølge oppfinnelsen også for vegg- simply and without taking into account the laborious manual laying of heating pipes in accordance with an all-too-individual pattern in each individual case. Furthermore, the building height can be kept very low and such heating elements can also be advantageously installed in older houses on existing floors. Of course, the heating element unit according to the invention is also adapted for wall-

og takmontasje. Takket være de små oppvarmete massene og det store kontaktområdet kan en holde temperaturen av transportmediet i varmerørene på lavest tenkbare nivå for også å oppnå rask, høy og pålitelig oppvarming. Dette gjør varmeelementene i samsvar med oppfinnelsen svært egnet for f.eks. varmepumpesystem o.l. Anvender en relativt tunge- dekkplater, kan spesielle forankringsmidler som skruer og plugger og eventuelt også liming unnværes. Den tidligere nevnte deformasjonen av varmerørene og/eller del:k--platen eksisterer fortrinnsvis ved siden av en viss permanent elastisitet og/eller mediumtrykk fra oppvarmings-mediet i rørene, slik at disse alltid presses til å ligge godt motdekkplatens underside, noe som garanterer god varmeoverføring. and ceiling assembly. Thanks to the small heated masses and the large contact area, the temperature of the transport medium in the heating pipes can be kept at the lowest imaginable level to also achieve fast, high and reliable heating. This makes the heating elements according to the invention very suitable for e.g. heat pump system etc. If a relatively heavy cover plate is used, special anchoring means such as screws and plugs and possibly also gluing can be dispensed with. The previously mentioned deformation of the heating pipes and/or part:k plate preferably exists next to a certain permanent elasticity and/or medium pressure from the heating medium in the pipes, so that these are always pressed to lie well against the underside of the cover plate, which guarantees good heat transfer.

Utførelsesformene som er beskrevet foran og vi< t på vedlagte tegninger er bare å betrakte som ikke-begrens-ende eksempler, som kan modifiseres og kompletteres på vilkårlig måte innenfor rammen av oppfinnelsen. Slik kan <;n istedenfor skruer hhv.<!>plugger også tenke seg at det gjennom cdé"kkplaten og bunnplaten går forankringselementer som popnagler o.l. The embodiments described in front of and on the attached drawings are only to be regarded as non-limiting examples, which can be modified and supplemented in any way within the scope of the invention. In this way, <;n instead of screws or <!>plugs, you can also imagine that anchoring elements such as pop rivets etc. go through the cover plate and the bottom plate.
