Den foreliggende opfindelse angår et dobbelt undertag og mere konkret en fremgangsmåde til opbygning af en tagkonstruktion, en dobbelt membran til anvendelse som dampspærre og undertag, et isoleringselement til 5 oplægning på et tag med tagspær, og en tagkonstruktion.The present invention relates to a double roof and more specifically to a method of building a roof structure, a double membrane for use as a vapor barrier and roof, an insulating element for mounting on a roof with roof rafters, and a roof structure.
Opfindelsen angår generelt tagkonstruktioner af den type, hvor der er tagspær, og hvor rummet imellem tagspærene helt eller delvis udnyttes til placering af isoleringsma-10 teriale. Denne konstruktionsmåde giver en maksimal udnyttelse af pladsen under taget, men den indebærer visse komplikationer i byggefasen og visse risici for senere opdukkende problemer.The invention generally relates to roof structures of the type where there are roof rafters and where the space between the roof rafters is utilized, in whole or in part, for the placement of insulating material. This design method maximizes the utilization of the space under the roof, but it involves certain complications during the construction phase and certain risks of later problems.
15 Under byggefasen vil det normalt være nødvendigt at sikre en vandtæt overdækning af taget, inden isoleringsmaterialet oplægges. Man er derfor nødt til at oplægge isoleringsmåtterne fra undersiden, hvilket er en vanskelig operation imellem skråtstillede lægter. Efter at 20 isoleringsmåtterne er oplagt og fastholdt mekanisk, opsættes dampspærren, typisk ved sømning mod tagspærenes underside. Risikoen for skader i dampspærren er stor, og når der efterfølgende skal opsættes installationer, f.eks. elektriske kabler, er det almindeligt, at det sker 25 ved gennembrydning af dampspærren dels for at skjule installationen, dels for at kunne fiksere sådanne komponenter til spærene.15 During the construction phase, it will usually be necessary to ensure a watertight covering of the roof before applying the insulation material. Therefore, the insulation mats have to be laid from the underside, which is a difficult operation between inclined laths. After the insulation mats are laid up and mechanically restrained, the vapor barrier is set up, typically by nailing to the underside of the roof rafters. The risk of damages in the vapor barrier is great, and when subsequent installations must be installed, e.g. electrical cables, it is common for 25 to break through the vapor barrier partly to conceal the installation and partly to be able to fix such components to the vents.
For at etablere den vandtætte overdækning af tagspærene, 30 inden isoleringen opsættes, er det i dag en ofte brugt procedure at lægge en fleksibel folie over tagspærene, * det som kaldes et undertag. Undertaget sikrer den regntætte afskærmning, således at man ikke er afhængig af ydertaget til denne funktion. Dette er hensigtsmæssigt, 35 fordi færdiggørelsen af ydertaget ofte tager længere tid.In order to establish the watertight covering of the roof rafters, 30 before the insulation is installed, it is nowadays a commonly used procedure to lay a flexible foil over the roof rafters, which is called a roof. The roof ensures the rainproof cover so that you do not depend on the outer roof for this function. This is appropriate, because the finishing of the outer roof often takes longer.
DK 173448 B1 2 F.eks. skal der opsættes afstandslister, taglægter og tagsten eller tagplader.DK 173448 B1 2 Eg. spacers, roofing and roof tiles or roofing panels must be installed.
De uundgåelige huller i dampspærren gør, at der ved tag-5 konstruktioner må forudses opfugtning på grund af opstigende rumluft og diffunderende fugt inde fra rummet. Det er derfor helt nødvendigt at ventilere isoleringsmaterialet underneden undertaget. Ventilationen må sikres ved at indrette et åbent rumfang imellem oversiden af isole-10 ringsmaterialet og undertaget og ved at indrette ventilationsåbninger til det fri. Der kendes på markedet også løsninger, hvor selve undertagsmaterialet er diffusionsåbent. Disse to muligheder rejser hver forskellige problemer. De åbne ventilationsrumfang kan være lukkede, 15 f.eks. på grund af et nedhængende undertag, fejlplaceret isoleringsmateriale eller andet, og de beslaglægger desuden plads i tagkonstruktionen. De diffusionsåbne undertagsmaterialer er undertiden ikke tilstrækkeligt vandtætte.The unavoidable holes in the vapor barrier means that for roof-5 constructions, humidification must be anticipated due to rising room air and diffusing moisture from inside the room. It is therefore imperative to ventilate the insulation material below the ceiling. Ventilation must be ensured by providing an open space between the top of the insulation material and the ceiling and by providing ventilation openings for the outdoors. Solutions are also known on the market, where the roofing material itself is diffusion open. These two options each raise different issues. The open vents may be closed, e.g. due to a suspended ceiling, misplaced insulation material or other, and they also occupy space in the roof structure. The diffusion open roofing materials are sometimes not sufficiently waterproof.
2020
Resultatet af disse forhold er, at opbygningen af disse tagkonstruktioner stadig er en kompliceret og kostbar proces, og at der ofte optræder store problemer med fugt.The result of these conditions is that the construction of these roof structures is still a complicated and costly process and that there are often major problems with moisture.
25 Fra tysk patentansøgning 24 12 830 kendes et isoleringselement, som omfatter en plade, et lag af isoleringsmateriale, en dampspærre og en indhylning omkring de øvrige komponenter. Elementet oplægges på den måde, at pladen støtter med kanterne på tagspærrene.25 German Patent Application 24 12 830 discloses an insulating element comprising a plate, a layer of insulating material, a vapor barrier and a casing around the other components. The element is arranged in such a way that the plate supports with the edges of the roof rafters.
30 Fladen holder gennem indhylningen isoleringen og dampspærren.30 The surface holds the insulation and the vapor barrier through the casing.
Indbygningen i et isoleringselement af en bærende plade er en tungtvejende omkostningsfaktor, og det komplicerer 35 håndteringen, transport og tilpasning til pladsforholdene så meget, at løsningen næppe vil være økonomisk DK 173448 B1 3 forsvarlig. Den bærende plade og den yderste side af indhylningen indfører desuden ekstra spærrende elementer på den kolde side af isoleringen, hvor disse ekstra elementer er i vejen for den ventilation til den kolde 5 side, som isoleringen kræver.The incorporation of an insulating element of a load-bearing plate is a weighty cost factor, and it complicates the handling, transport and adaptation to the space conditions so much that the solution will hardly be economically viable. In addition, the supporting plate and the outer side of the casing introduce additional blocking elements on the cold side of the insulation, where these additional elements interfere with the ventilation to the cold side that the insulation requires.
Ifølge opfindelsen tilvejebringes en fremgangsmåde som angivet i krav 1. Ved denne fremgangsmåde lægges den membran, som danner dampspærren, oven over tagspærene, og lo isoleringsmaterialet imellem tagspærene presser randområder af membranen imod tagspærenes sider. Selve tagspærene bliver derved damptæt afskærmet på oversiden og på det meste af sidefladerne, således at tagspærene er frie til tagets underside (rumsiden). Fugt fra tagspærene kan 15 derfor ikke komme over i isoleringsmaterialet. Tagspærene er frit tilgængelige for håndværksoperationer, såsom opsætning af installationer m.v. uden risiko for, at membranen gennembrydes derved. Den tætte aflukning langs tagspærenes sider sikrer, at der ikke trænger rumluft op 20 i mellemrummet.According to the invention there is provided a method as claimed in claim 1. In this method, the membrane forming the vapor barrier is laid over the roof rafters and the insulating material between the roof rafters pushes peripheral areas of the membrane against the sides of the roof rafters. The roof rafters themselves are thereby vapor-proofed on the upper side and on most of the side surfaces, so that the roof rafters are free to the underside of the roof (room side). Therefore, moisture from the roof rafters cannot enter the insulation material. The roof rafters are freely available for craft operations, such as setting up installations, etc. without the risk of the membrane breaking through. The close closure along the sides of the roof rafters ensures that no room air enters 20 in the space.
Det forhold, at membranen til dampspærre har en optimal afstøtning på tagspærene, gør, at membranen kan udnyttes som strukturelt element til at bære isoleringsmaterialet, 25 så at det kan oplægges fra oversiden. Når isoleringsmaterialet er oplagt, f.eks. langs med en bane, kan undertaget meget hurtigt bringes på plads oven over isoleringsmaterialet, således at der ikke er risiko for vejrbetinget opfugtning af isoleringen. Selve 30 oplægningsprocessen er betydeligt enklere end de kendte metoder.The fact that the membrane for vapor barrier has an optimum impact on the roof rafters means that the membrane can be utilized as a structural element for supporting the insulating material, so that it can be laid from the top. When the insulating material is obvious, e.g. along with a web, the roof can very quickly be placed in place above the insulation material, so that there is no risk of weather condensation of the insulation. The 30 process itself is considerably simpler than the known methods.
Ifølge opfindelsen tilvejebringes en dobbelt membran som angivet i krav 2. Denne membran kan leveres som færdigt 35 produkt, f.eks. i ruller med en bredde svarende til afstanden mellem to tagspær. Membranen anvendes på den DK 173448 B1 4 måde, at en bane rulles ned og fastsømmes langs den kant, hvor de to membranbaner er sammensvejset. Den bredeste af banerne ligger nederst, og den fastsømmes ved sin modsatte kant mod oversiden af nabotagspæret. Herefter 5 kan isoleringsmåtterne lægges ovenpå, og den smalleste membran, som danner undertaget, placeres og' fikseres.According to the invention there is provided a double membrane as claimed in claim 2. This membrane can be supplied as a finished product, e.g. in rolls with a width corresponding to the distance between two roof rafters. The membrane is used in the way that a web is rolled down and fixed along the edge where the two membrane webs are welded together. The widest of the lanes is located at the bottom and it is fixed at its opposite edge to the upper side of the neighboring rafter. Thereafter, the insulation mats can be laid on top and the narrowest membrane forming the lower ceiling is placed and fixed.
Ifølge en hensigtsmæssig udførelsesform er de to membranbaner sammensvejset langs begge kanter, så at de danner 10 en slange. Ved dette produkt skubbes isoleringsmåtterne ind i slangen på langs, enten før eller efter at membranerne er fastgjort til tagspærenes oversider.According to a convenient embodiment, the two membrane webs are welded along both sides to form a hose. With this product, the insulation mats are pushed into the hose longitudinally, either before or after the membranes are attached to the tops of the roof rafters.
Ifølge opfindelsen tilvejebringes et isoleringselement 15 som angivet i krav 4. Dette udgør en form for præfabrikeret element, som kan fremstilles effektivt på fabrik, som er vandtæt i sig selv, så at det kan tåle at henligge på byggepladsen, og som er let at' opsætte, hvorved man i én operation opnår både dampspærreisolering og undertag.According to the invention there is provided an insulating element 15 as claimed in claim 4. This constitutes a form of prefabricated element which can be effectively manufactured in a factory which is waterproof in itself, so that it can withstand the construction site and which is easy to install. set up, which in one operation achieves both vapor barrier insulation and roofing.
2020
Ifølge opfindelsen tilvejebringes der en tagkonstruktion som angivet i krav 5.According to the invention there is provided a roof structure as claimed in claim 5.
Denne tagkonstruktion giver mulighed for en forenkling af 25 byggeprocessen og en forkortelse af den tid, hvor den fugtfølsomme isolering ligger udsat for vejrliget.This roof construction allows for a simplification of the 25 construction process and a shortening of the time when the moisture-sensitive insulation is exposed to the weather.
Membranen kan oplægges fra oversiden og den tilvejebringer straks et bærende element, hvor isoleringsmaterialet meget enkelt kan udlægges. Herefter 30 kan undertaget bringes på plads, således at beskyttelsen mod regn er etableret.The membrane can be laid from the top and it immediately provides a supporting element where the insulating material can be laid out very easily. Thereafter 30 can sometimes be brought into place so that the protection against rain is established.
Ifølge en hensigtsmæssig udførelsesform opsættes der efterfølgende fra indersiden yderligere isoleringsmateriale 35 på indersiden af dampspærren, og der opsættes derefter vægplader til afslutning. På denne måde kommer dampspær- DK 173448 B1 5 ren til at sidde tilbagetrukket i forhold til indervæg-gen, så at der er plads til at trække elektriske kabler og lignende i rummet mellem indervæg og dampspærre uden at gennembryde dampspærren. Placeringen af dampspærren i 5 en vis afstand fra inderbeklædningselementerne mindsker også risikoen for, at dampspærren utilsigtet bliver punkteret ved håndværksarbejder. Tykkelsen af den supplerende isolering holdes fortrinsvis under eller lig med det halve af tykkelsen af isolering på dampspærrens overside 10 for at undgå kondensering på dampspærrens inderside.According to a suitable embodiment, additional insulation material 35 is subsequently set up from the inside of the inside of the vapor barrier and wall plates are then set up for completion. In this way, the vapor barrier is cleanly retracted relative to the inner wall, so that there is room for pulling electrical cables and the like in the space between the inner wall and the vapor barrier without breaking the vapor barrier. The location of the vapor barrier at a certain distance from the interior lining elements also reduces the risk of the vapor barrier being accidentally punctured by craftsmen. The thickness of the supplemental insulation is preferably kept below or equal to half the thickness of insulation on the top surface of the vapor barrier 10 to avoid condensation on the inside of the vapor barrier.
Yderligere ejendommeligheder og fordele ved opfindelsen vil fremgå af den følgende detaljerede beskrivelse af hensigtsmæssige udførelsesformer, som gives under henvis-15 ning til tegningen, hvorpå fig. 1 viser en tagkonstruktion ifølge opfindelsen i et snit vinkelret på tagspærenes længdeakser, 20 fig. 2 viser et snitbillede svarende til fig. 1 under et trin af arbejdsprocessen, hvor kun dobbeltmembranen er opsat, fig. 3 viser et snit i en dobbelt membran ifølge op-25 findel sen, og fig. 4 viser et snit i et isoleringselement ifølge opfindelsen.Further features and advantages of the invention will become apparent from the following detailed description of suitable embodiments given with reference to the accompanying drawings, in which: 1 shows a roof construction according to the invention in a section perpendicular to the longitudinal axes of the roof rafters; FIG. 2 shows a sectional view similar to FIG. 1 during a step of the working process in which only the double membrane is set up; FIG. 3 is a sectional view of a double membrane according to the invention, and FIG. 4 shows a section in an insulating element according to the invention.

I alle figurer betegnes de samme elementer med de samme henvis-35 ningstal.All figures are schematic and not necessarily purposeful, and show only details that are essential to the understanding of the invention, while other details which are of a professional nature are omitted for the sake of clarity. In all figures, the same elements are denoted by the same reference numerals.
DK 173448 B1 6DK 173448 B1 6
Der henvises først til fig. 1, som viser et snit i en komplet tagkonstruktion 1. De bærende elementer i tagkonstruktionen er spærene 2, som forløber skråt og indbyrdes parallelt fra tagrygningen og ned til tagets laveste 5 kant. Typiske taghældninger, hvor denne konstruktionsmåde anvendes, kan være fra 12° til 45° i forhold til vandret.Referring first to FIG. 1, which shows a section in a complete roof structure 1. The supporting elements of the roof structure are the rafters 2, which extend obliquely and mutually parallel from the roof ridge down to the lowest edge of the roof. Typical roof slopes where this design method is used can be from 12 ° to 45 ° relative to the horizontal.
Ved tagkonstruktionen vist i fig. 1 er der i mellemrummet mellem spærene placeret isoleringsmateriale 3 og 4, og 10 der er langs med spærenes oversider 5 arrangeret et undertag 6. Undertaget er fikseret til tagspærenes oversider ved søm 7. Ovenpå er der lagt afstandslister 8 parallelt med spærene og herovenpå lægter 9 i retning vinkelret på spærene. Oven på lægterne placeres ydertaget 10, 15 som f.eks. kan omfatte tagsten. Afstandslisterne 8 har til formål at give plads til, at vand, som løber ned på oversiden af undertaget, kan passere under lægterne.In the roof construction shown in FIG. 1, insulating material 3 and 4 is placed in the space between the rafters and 10 is arranged along a roof top along the tops 5 of the rafters 6. The roof is fixed to the roof tops at the nails 7. Spacer strips 8 are placed parallel to the rafters and overlays 9. in the direction perpendicular to the rafters. On top of the laths, the outer roof 10, 15 is placed, e.g. may include roof tiles. The spacer strips 8 are intended to provide space for water running down the top of the roof to pass under the laths.
Tagkonstruktionen i fig. 1 omfatter en dampspærre 11, og 20 den er ifølge opfindelsen og som vist i fig. 1 ført langs med oversiderne 5 af tagspærene, ned langs med en del af tagspærenes sideflader 11 og tværs over mellemrummet imellem to tagspær.The roof structure of FIG. 1 comprises a vapor barrier 11 and 20 it is according to the invention and as shown in FIG. 1 is passed along the upper sides 5 of the roof rafters, down along a portion of the roof surfaces 11 of the roof rafters and across the space between two roof rafters.
25 Som vist i fig. 1 ligger der supplerende isoleringsmateriale, nemlig inderisoleringen 4, imellem dampspærren 11 og en loftbeklædning 12, som er plan og flugter med tagspærenes undersider 13. Dampspærren er således trukket lidt tilbage fra loftbeklædningen 12.25 As shown in FIG. 1, there is additional insulation material, namely the insulation 4, between the vapor barrier 11 and a ceiling covering 12 which is flat and flush with the undersides of the roof rafters 13. The vapor barrier is thus withdrawn slightly from the ceiling covering 12.
30 Dette mindsker risikoen for, at man f.eks. ved boring eller sømning i loftbeklædningen utilsigtet kommer til at perforere dampspærren. Endvidere giver det plads for at indrette ledningsrør og lignende i skjul bag ved loftbeklædningen, men uden at man bliver nødt til at 35 gennembryde dampspærren.30 This reduces the risk of e.g. when drilling or nailing in the ceiling lining will inadvertently perforate the vapor barrier. Furthermore, it provides space for arranging conduits and the like in hiding behind the ceiling lining, but without having to break through the vapor barrier.

Der henvises nu til fig. 2 og 3 for en beskrivelse af en dobbeltmembran ifølge opfindelsen og en beskrivelse af oplægningsprocessen.Referring now to FIG. 2 and 3 for a description of a double membrane according to the invention and a description of the laying process.
5 Dobbeltmembranen 14 omfatter to foliebaner forbundet langs den ene kant ved en svejsning 15. Foliebanerne har forskellig bredde. Den foliebane, som er vist øverst i fig. 3, og som danner undertaget 6, er afpasset, så at den netop kan spænde nogenlunde retlinet imellem 10 oversiderne af to nabotagspær. Den anden foliebane, som danner dampspærren 11, har en overlængde i forhold hertil. Bredden af den øverste foliebane kan f.eks. være 100 cm og bredden af den nederste 130 cm svarende til en tagkonstruktion, hvor der er 90 cm mellemrum imellem 15 tagspærene, og hvor højden af tagspærene er 20 cm.The double membrane 14 comprises two foil webs connected along one edge by a weld 15. The foil webs have different widths. The film web shown at the top of FIG. 3, and forming the lower ceiling 6, is adapted so that it can precisely span approximately the rectangle between 10 the upper sides of two adjacent roof rafters. The second foil web forming the vapor barrier 11 has an overlength relative thereto. The width of the top foil web can e.g. be 100 cm and the width of the lower 130 cm corresponding to a roof structure, where there is a 90 cm gap between the 15 roof rafters and the height of the roof rafters is 20 cm.
Dobbeltmembranen oplægges som vist i fig. 2, idet den svejsede kant fastsømmes på oversiden af det ene tagspær, og randen af den bredeste foliebane, som skal danne 20 dampspærren 11, sømmes fast til det overfor beliggende tagspær. Foliebanen her har en overbredde, så at den kan hænge noget ned i mellemrummet imellem tagspærene. Den lidt smallere øverste foliebane foldes til siden som vist i fig. 2. Herefter kan isoleringsmåtter tilskåret i 25 passende bredde oplægges, idet dampspærren 11 udnyttes som strukturelt understøtningselement til at bære isoleringsmåtten. Når isoleringsmåtten er oplagt, foldes den foliebane, som danner undertaget 6, på plads og fikseres langs den frie kant til afslutning af 30 konstruktionen.The double membrane is laid out as shown in FIG. 2, the welded edge being secured to the upper side of one roof rafter, and the rim of the widest foil web to form the steam barrier 11 being seamed to the opposite roof rafter. The foil web here has a cover so that it can hang slightly in the space between the roof rafters. The slightly narrower upper foil web folds to the side as shown in FIG. 2. Thereafter, insulation mats cut to a suitable width can be laid, using the vapor barrier 11 as a structural support element to support the insulating mat. When the insulating mat is laid out, the foil web forming the bottom 6 is folded in place and fixed along the free edge to complete the construction.
Der henvises endvidere til fig. 4, som viser et snit i et isoleringselement ifølge opfindelsen. Dette isoleringselement 16 omfatter en øverste foliebane til undertag 6, 35 som er stort set plan, en måtte af isolering 3 og en underste folie til at danne dampspærren 11. De to DK 173448 B1 8 foliebaner er sammensvej set langs begge kanter. Den underste folie har en over længde, så at den kan rumme måtten af isoleringsmateriale, mens den øverste foliebane forløber plant.Referring also to FIG. 4, which shows a section in an insulating element according to the invention. This insulating element 16 comprises an upper foil web for roof 6, 35 which is substantially planar, a mat of insulation 3 and a lower foil for forming the vapor barrier 11. The two foil webs are welded together along both sides. The lower foil has an over length so that it can accommodate the mat of insulating material while the top foil path runs flat.

Ved tagkonstruktionen ifølge opfindelsen er isoleringsmaterialet næsten hermetisk indelukket, og sikkerheden for tæthed af dampspærren er så god, at der ikke kræves ventilering af isoleringsmaterialet. Det er 10 derfor ikke nødvendigt at indrette tagkonstruktionen med en overhøjde til at danne et ventilationsrum. Inden for en given tagkonstruktion bliver der plads til mere isoleringsmateriale.In the roof construction according to the invention, the insulation material is almost hermetically enclosed and the safety of the vapor barrier tightness is so good that no ventilation of the insulation material is required. Therefore, it is not necessary to arrange the roof structure with an overhead to form a ventilation room. Within a given roof structure there is room for more insulating material.
15 Som materiale til foliebanerne kan der anvendes polyethylenfolie eller andre plastfolier, f.eks. i tykkelser på fra 0,15 til 1 mm. De største tykkelser er så kraftige, at undertaget bliver trædesikkert. Folien til undertag og folien til dampspærre kan være af 20 identiske materialer, eller de kan være forskellige, til undertag kan det f.eks. være hensigtsmæssigt at anvende tagpap eller et andet materiale.As a material for the film webs, polyethylene film or other plastic films can be used, e.g. in thicknesses of 0.15 to 1 mm. The largest thicknesses are so strong that the ceiling becomes tree-proof. The foil for the roof and the foil for the vapor barrier may be of 20 identical materials or they may be different. be suitable to use roofing paper or other material.
