Downlight box og fremgangsmåde til etablering af en elektrisk installation med en sådan boxDownlight box and method for establishing an electrical installation with such a box
Opfindelsen vedrører en downlight box til anbringelse i en loftskonstruktion 5 således, at boxens underside i det væsentlige flugter med oversiden af en loftsbeklædning.The invention relates to a downlight box for placement in a ceiling structure 5 such that the underside of the box substantially aligns with the top of a ceiling covering.
Det er almindeligt kendt at anbringe loftsdåser i tagkonstruktionerne, således at dåsens underside flugter med oversiden af den færdige loftsbeklædning.It is generally known to place ceiling boxes in the roof structures so that the underside of the can aligns with the top of the finished ceiling covering.
10 Loftsbeklædningen anbores derefter for montage af elektriske udtag, down-lights eller andet.10 The ceiling covering is then drilled for mounting of electrical outlets, down-lights or other items.
Downlight boxe adskiller sig principielt kun fra almindelige dåser til elektriske udtag ved, at downlight boxen har en relativt stor højde for at kunne bortlede 15 den varme, der afgives fra lysarmaturet. Specielt ved de relativt høje downlight boxe, se f.eks. WO 2006/007852, men også ved de relativt lavere, almindelige dåser til andet elektrisk installationsmateriel, se f.eks. NO 316544, er det et problem at få arbejdet udført således og i en sådan rækkefølge, at den dampspærre, der som bekendt skal anbringes på den varme side af iso-20 lationsmaterialet, ikke gennembrydes flere steder for at man kan trække ledninger og kabler mellem dåserne eller boxene. Det har tidligere været meget anvendt at lægge et elektrikerrør på den kolde side af isolationsmaterialet, og da de kendte boxe eller dåser ikke er diffusionstæt adskilt fra den varme fugtige luft i bygningen, trænger denne ud i de kolde rør og kondenserer. Dette 25 giver anledning til fugt, overgang og kortslutning og i sidste ende brand.In principle, downlight boxes differ only from ordinary cans to electrical outlets in that the downlight box has a relatively high height to be able to dissipate the heat emitted from the light fixture. Especially with the relatively high downlight boxes, see e.g. WO 2006/007852, but also at the relatively lower, ordinary cans for other electrical installation equipment, see e.g. NO 316544, it is a problem to have the work done so and in such an order that the vapor barrier which, as is well known, must be placed on the hot side of the insulation material is not pierced in several places in order to pull wires and cables between the cans or boxes. It has been widely used in the past to place an electric pipe on the cold side of the insulation material, and since the known boxes or cans are not diffusion-tightly separated from the hot humid air in the building, it penetrates into the cold pipes and condenses. This 25 gives rise to moisture, transition and short circuit and ultimately fire.
Ved begge de nævnte eksempler på den kendte teknik er huller til rør eller kablet beliggende over dampspærren. Ved WO 2006/007852 findes der endog sådanne huller højt oppi i boxen svarende til den kolde del af isoleeringen.In both of the aforementioned examples of the prior art, holes for pipe or cable are located above the vapor barrier. At WO 2006/007852 there are even such holes high up in the box corresponding to the cold part of the insulation.
30 DK 176703 B1 230 DK 176703 B1 2
Formålet med opfindelsen er at angive en downlight box, som gør det muligt at udføre den elektriske installation således, at der både kan opnås en relativt stor byggehøjde for boxen, og således at boxens indre og de tilhørende elektriske installationer udelukkende vender imod bygningens varme rum, 5 uden risiko for at der sker en perforering af dampmembranen.The object of the invention is to provide a downlight box which makes it possible to carry out the electrical installation so that both the relatively high building height of the box can be obtained and so that the interior of the box and the associated electrical installations face only the building's warm space, 5 without the risk of perforation of the vapor membrane.
Dette formål opnås ved, at boxen omfatter en overdel og en underdel, som har indbyrdes samvirkende koblingsorganer på en respektiv rand, som er i det væsentlige parallel med nævnte underside, og at mindst én af underde-10 lens sider har huller eller brudanvisninger for huller til optagelse af elektriske installationsrør eller -kabler, idet underdelens højde er lig med eller større end tykkelsen af de elektriske installationsrør eller-kabler.This object is achieved in that the box comprises an upper part and a lower part having mutually interacting coupling means on a respective edge which is substantially parallel to said underside, and that at least one of the sides of the lower part has holes or holes for breaking holes. for receiving electrical installation pipes or cables, the height of the base being equal to or greater than the thickness of the electrical installation pipes or cables.
Opfindelsen angår også en fremgangsmåde til etablering af en elektrisk in-15 stallation i en loftskonstruktion omfattende tagbjælker, hvor der benyttes downlight boxe af ovennævnte art, som forbindes indbyrdes ved hjælp af elektriske installationsrør eller -kabler, og hvor boxens underside i det væsentlige flugter med oversiden af en loftsbeklædning.The invention also relates to a method of establishing an electrical installation in a ceiling structure comprising roof beams, using downlight boxes of the above-mentioned type, which are interconnected by means of electrical installation pipes or cables, and wherein the underside of the box substantially aligns with the top of a ceiling covering.
20 Fremgangsmåden er egendommelig ved, • at der anvendes en i højden todelt downlight box, • at en øvre del af boxen anbringes således, at dens underkant i hovedsagen flugter med undersiden af tagbjælkerne, • at der anbringes en dampspærre på undersiden af tagbjælkerne, 25 · at underdelen af downlight boxen monteres på overdelen, således at dampspærren klemmes inde mellem boxens overdel og underdel, og at • loftsbeklædningen anbringes op mod boxens underdel.The method is peculiar in that: • a height-divided downlight box is used, • that an upper part of the box is arranged so that its bottom edge aligns substantially with the underside of the roof beams, • that a vapor barrier is applied to the underside of the roof beams, 25 · The bottom of the downlight box is mounted on the top so that the vapor barrier is squeezed in between the top and bottom of the box and • the ceiling covering is placed against the bottom of the box.

Ved udøvelse af denne fremgangsmåde vil det umiddelbart kunne forstås, hvilke tekniske forbedringer, der opnås ved downlight boxen ifølge opfindelsen.In practicing this method, it will be immediately understood what technical improvements are achieved by the downlight box of the invention.
5 Boxen og arbejdsprocessen er også meget hensigtsmæssig i forhold til de arbejdsgange i et byggeri, hvor forskellige fag flettes ind i hinanden. Når tømreren har lagt tagbjælkerne, kan installatøren eller tømreren selv anbringe overdelen af downlight boxen og andre loftsdåser således, at boxe-nes/dåsernes underkant flugter med undersiden af tagbjælkerne. Derefter 10 anbringes dampspærren under tagbjælkeme og boxene/dåseme, hvorefter der skal lægtes ned et stykke, som i det mindste svarer til højden for boxens underdel, som igen i det mindste er lig med eller større end tykkelsen af det anvendte installationskabel eller rørmateriale. Derefter kan elektrikeren gå i gang med at montere underdelene til boxene og forbinde rør og kabler mel-15 lem boxene indbyrdes uden at der på nogen måde er risiko for perforering af dampspærren.5 The box and the work process are also very suitable in relation to the workflows in a building where different subjects are intertwined. When the carpenter has laid the roof beams, the installer or carpenter can himself place the top of the downlight box and other ceiling boxes so that the bottom of the boxes / cans aligns with the underside of the roof beams. Then, the vapor barrier is placed under the roof beams and boxes / cans, after which a piece must be laid which is at least equal to the height of the bottom of the box, which in turn is at least equal to or greater than the thickness of the installation cable or pipe material used. The electrician can then proceed to mount the lower parts to the boxes and connect the pipes and cables between the boxes without any risk of perforating the vapor barrier.
Ved en foretrukken udførelsesform udføres fremgangsmåden ved, • at en del af dampspærren, som er beliggende under overdelen, skæ- 20 res op, således • at der etableres flige af dampspærren, som strækker sig mod hinanden fra hver sin respektive underkant af overdelen, og • at fligene presses opad til anlæg mod overdelens indvendige sidevægge ved hjælp af opadragende flanger på underdelen, når denne 25 monteres op under overdelen.In a preferred embodiment, the method is carried out by cutting a portion of the vapor barrier located below the top so as to establish tabs of the vapor barrier extending towards each other from its respective lower ends of the top, and • the tabs are pressed upwards for abutment against the inner side walls of the upper part by means of upwardly extending flanges on the lower part as it is mounted under the upper part.
Dette er en meget enkel måde at sikre, at downlight boxens indre slutter tæt til dampspærren. Alternativt kunne boxens overdel være forsynet med et selvklæbende materiale langs den nedad vendende rand. Downlight boxens 30 underdel vil typisk have en højde, som svarer til de mest anvendte standard-dimensioner for de lægter, som man anbringer under tagbjælkerne. Der kan DK 176703 B1 4 enten findes flere højder på underdele, eller findes en lav underdel, som kan sammenkobles med afstand s ringe. Hvis underdelen består af flere komponenter, er det ikke nødvendigt, at disse indbyrdes er damptætte, da det alene er tætheden imellem dampmembranen og boxens overdel, som er afgøren-5 de.This is a very simple way to make sure the downlight box's interior ends close to the vapor barrier. Alternatively, the top of the box could be provided with a self-adhesive material along the downward edge. The lower part of the downlight box 30 will typically have a height which corresponds to the most commonly used standard dimensions for the laths that are placed under the roof beams. DK 176703 B1 4 can either find several heights on lower parts, or a low lower part can be found that can be connected with spacings. If the lower part consists of several components, it is not necessary for these to be vapor-tight, since it is only the density between the vapor membrane and the upper part of the box that is decisive.
Ved en foretrukken udførelsesform findes der nogle fremspringende låsetappe i hjørnerne af den ene boxdel, mens den anden boxdel har modsvarende huller til optagelse og fastlåsning af nævnte tappe. I praksis vil man derfor 10 montere underdelen på overdelen ved at forskyde underdelen lodret opad, således at tappene griber ind i hullerne. Ved denne lodret opadgående bevægelse kan membranen klemmes inde mellem en opadragende flange på boxens underdel og de indvendige sidevægge af boxens overdel.In a preferred embodiment, some projecting locking pins are provided in the corners of one box part, while the other box part has corresponding holes for receiving and locking said pins. In practice, therefore, the bottom part will be mounted on the upper part by displacing the lower part vertically upwards so that the pins engage the holes. With this vertical upward movement, the diaphragm can be squeezed in between an upwardly extending flange on the bottom of the box and the inner side walls of the top of the box.
15 Opfindelsen vil blive nærmere forklaret ved den følgende beskrivelse af en udførelsesform, idet der henvises til tegningen, hvor fig. 1 viser en udførelsesform for en downlight box ifølge opfindelsen, 20 fig. 2 viser overdelen af downlight boxen fra fig. 1, fig. 3 viser underdelen af downlight boxen fra fig. 2, fig 4 viser et lodret snit gennem et eksempel på en loftskonstruktion med en 25 downlight box ifølge opfindelsen, mens fig. 5 viser det samme som fig. 4, men på et senere tidspunkt i monteringsforløbet.The invention will be explained in more detail by the following description of an embodiment, with reference to the drawing, in which fig. 1 shows an embodiment of a downlight box according to the invention; FIG. 2 shows the top of the downlight box of FIG. 1, FIG. 3 shows the bottom of the downlight box of FIG. 2, FIG. 4 shows a vertical section through an example of a ceiling structure with a downlight box according to the invention, while FIG. 5 shows the same as FIG. 4, but at a later stage in the assembly process.
30 Den på fig. 1 viste udførelsesform for downlight boxen 1 adskiller sig principielt ikke fra en almindelig loftsdåse, men adskiller sig dog i dimensionerne, DK 176703 B1 5 fordi en downlight box er større, især i højden, fordi boxen skal kunne fordele varmen fra lysarmaturet i boxen til omgivelserne. Ifølge opfindelsen består downlight boxen af en overdel 2 og en underdel (eller flere) 3. Underdelen 3 er på en eller flere sider forsynet med huller eller brudanvisninger 4, således 5 at der kan trækkes kabler eller elektriske installationsrør ind gennem et sådant hul. Ifølge opfindelsen er højden af underdelen 3 større end eller lig med tykkelsen på det anvendte instal!ationsrør/-kabel, og downlight boxen er egendommelig ved, at den tillader, at loftskonstruktionens dampspærre kan være beliggende mellem overdelen 2 og underdelen 3, og på en sådan må-10 de, at dampspærren kan forbindes damptæt til overdelen 2. Som det senere vil blive forklaret i forbindelse med fig. 4 og 5, er det derved muligt at etablere en elektrisk installation fuldstændigt under dampspærren og uden risiko for, at denne bliver gennembrudt.The embodiment of FIG. 1 embodiment of the downlight box 1 does not in principle differ from a regular ceiling box, but differs in dimensions, because a downlight box is larger, especially in height, because the box must be able to distribute the heat from the light fixture in the box to the surroundings. . According to the invention, the downlight box consists of an upper part 2 and a lower part (or more) 3. The lower part 3 is provided on one or more sides with holes or bridging instructions 4, so that cables or electrical installation pipes can be drawn through such a hole. According to the invention, the height of the lower part 3 is greater than or equal to the thickness of the installation pipe / cable used, and the downlight box is characterized in that it allows the vapor barrier of the ceiling structure to be located between the upper 2 and the lower 3, and on a in such a way that the vapor barrier can be connected vapor tightly to the upper part 2. As will be explained later in connection with FIG. 4 and 5, it is thereby possible to establish an electrical installation completely under the vapor barrier and without the risk of it being pierced.
15 Fig. 2 viser overdelen 2 af downlight boxen, som på et par modstående sider har sideflanger 5, som fortrinsvist anvendes til at fastgøre overdelen 2 af boxen til en tagbjælke. I hjørnerne af overdelen 2 findes der huller 6, som er indrettet til at optage låsetappe 7, som kan ses på underdelen 3, der er vist på fig. 3. Underdelen 3 har endvidere nogle sideflanger 8, som har en hæld-20 ning, der modsvarer hældningen for sidevæggene for overdelen 2, og som har en dimension, således at flangerne 8 netop indeklemmer dampspærren stramt mellem flangerne og sidevæggene på overdelen 2.FIG. 2 shows the upper part 2 of the downlight box, which on a pair of opposite sides has side flanges 5, which are preferably used to attach the upper part 2 of the box to a roof beam. In the corners of the upper part 2 there are holes 6 arranged to receive locking pins 7, which can be seen on the lower part 3 shown in FIG. 3. The lower part 3 also has some side flanges 8 which have an inclination corresponding to the inclination of the side walls of the upper part 2 and which have a dimension such that the flanges 8 precisely clamp the vapor barrier tightly between the flanges and the side walls of the upper part 2.
Fig. 4 viser et lodret snit gennem en loftskonstruktion omfattende en tagbjæl-25 ke 10, på hvilken der er anbragt en overdel 2 af en downlight box ifølge opfindelsen. Så snart downlight boxen er anbragt, kan der monteres en dampspærre 11 under tagbjælkerne, hvorefter der kan monteres en underdel 3 af boxen og lægter 12, som skal bære loftsbeklædningen. Rækkefølgen af anbringelsen af lægterne 12 og underdelene 3 er ikke afgørende. Derimod er 30 det afgørende, at dampspærren klemmes inde eller på anden måde forbindes damptæt til boxens overdel 2, hvilket ved en foretrukken udførelsesform DK 176703 B1 6 kan opnås ved at skære membranen op ud for overdelen 2, således som det er antydet på fig. 4. Derefter presses underdelen 3 opad og på plads, således at tappene 7 låses fast i hullerne 6, hvorved dampspærren klemmes inde imellem over- og underdelen.FIG. 4 shows a vertical section through a ceiling structure comprising a roof beam 10 on which is placed a top 2 of a downlight box according to the invention. As soon as the downlight box is placed, a vapor barrier 11 can be mounted under the roof beams, after which a lower part 3 of the box and luminaires 12 can be mounted to carry the ceiling covering. The order of placement of the laths 12 and the lower parts 3 is not essential. On the other hand, it is essential that the vapor barrier is clamped inside or otherwise connected vapor tightly to the upper part 2 of the box, which in a preferred embodiment DK 176703 B1 6 can be obtained by cutting the diaphragm out of the upper part 2, as indicated in FIG. 4. Then the bottom part 3 is pressed upwards and in place, so that the pins 7 are locked in the holes 6, whereby the vapor barrier is squeezed in between the upper and lower parts.

Det er naturligvis afgørende, at højden for underdelen 3 svarer til højden for lægterne 12, således at undersiden af underdelen 3 i hovedsagen flugter med undersiden af lægterne 12, og således at undersiden af den monterede downlight box ikke rager længere ned men helst passer i højde med oversi-10 den af loftsbeklædningen, som er vist ved 13 på fig, 5,Of course, it is crucial that the height of the lower part 3 corresponds to the height of the laths 12, so that the underside of the lower part 3 aligns substantially with the underside of the laths 12, and so that the underside of the mounted downlight box does not extend further but preferably fits in height with the top 10 of the ceiling covering shown at 13 in FIG. 5,
Fig. 5 viser, at overdelen 2 og underdelen 3 er samlet, og at membranen 11 er indeklemt mellem disse deles henholdsvis sidevægge og flanger. Fig. 5 viser også installationsrør 14, 15, hvor røret 15 er vist således, at det stræk-15 ker sig gennem en lægte 12. Uanset hvordan man trækker rørene, er der ingen risiko for, at dampmembranen bliver perforeret.FIG. 5 shows that the upper part 2 and the lower part 3 are assembled and that the membrane 11 is sandwiched between the partitions and flanges of the parts respectively. FIG. 5 also shows installation pipes 14, 15, where the pipe 15 is shown to extend through a bed 12. Regardless of how the pipes are pulled, there is no risk of the steam membrane being perforated.
Når loftet er færdigt og malet, anbores loftet nedefra med en hulbor, som skærer op gennem loftsbeklædningen 13 og undersiden af downlight boxen, 20 hvorefter der kan anbringes et lysarmatur 16. Anboringen kan let udføres ved at anvende en i og for sig kendt magnet i downlight boxen.When the ceiling is finished and painted, the ceiling is drilled from below with a hollow drill which cuts through the ceiling cladding 13 and the underside of the downlight box 20, whereupon a light fixture 16. The drilling can be easily carried out using a magnet known per se. downlight boxes.
Det vil kunne forstås, at dampspærren 11 kan fastgøres damptæt til downlight boxens overdel 2 på andre måder end beskrevet, f.eks. ved hjælp af 25 limning eller tape. Det vil også kunne forstås, at samleorganerne såsom de beskrevne huller og tappe 6, 7 kan være udformet på mange andre måder, f.eks. ved hjælp af skruer. Hullerne eller anboringerne 4 ertypisk udformet i to eller flere standarddimensioner.It will be appreciated that the vapor barrier 11 can be attached vapor tightly to the downlight box top 2 in other ways than described, e.g. using 25 bonding or tape. It will also be appreciated that the collecting means such as the holes and pins 6, 7 described can be formed in many other ways, e.g. using screws. The holes or bores 4 are typically formed in two or more standard dimensions.
