Description

Fremgangsmåte ved festing av isolerende og tettende sjikt samt anordning for utførelse av fremgangsmåten. Procedure for attaching an insulating and sealing layer as well as a device for carrying out the procedure.

Den foreliggende oppfinnelse vedrører en fremgangsmåte ved festing av isolerende og tettende sjikt samt en anordning for utførelse av fremgangsmåten, slik som angitt i ingressen av etterfølgende patentkrav. The present invention relates to a method for attaching an insulating and sealing layer as well as a device for carrying out the method, as indicated in the preamble of subsequent patent claims.

Det vanligste prinsipp ved festing av nevnte materialer er å benytte klebing. Hvis arbeidet skal foregå ute, f.eks. ved isolering og/ eller tetting av tak, er imidlertid mekanisk befestigelse et langt mer væruavhengig prinsipp. The most common principle for attaching the aforementioned materials is to use gluing. If the work is to take place outside, e.g. when insulating and/or sealing roofs, however, mechanical fastening is a far more weather-independent principle.

Det er kjent en rekke systemer for å utføre slik mekanisk befestigelse. A number of systems are known for performing such mechanical fastening.

■Et flippesystem lansert av søkeren består i at det på undersiden av konfeksjonerte flak av "SARNAFIL SE" sveises flipper av samme materiale med senteravstand 60-70 cm. Etterhvert som flaket rulles ut på taket, festes flippene ved hjelp av skruer, stifter, kramper e.l. avhengig av type underlag. Flak med flipper er imidlertid ma-terialkrevende og dessuten kompliserte å fremstille. ■A flipper system launched by the applicant consists of welding flippers of the same material with a center distance of 60-70 cm on the underside of prefabricated flakes of "SARNAFIL SE". As the sheet is rolled out onto the roof, the flaps are attached using screws, staples, clamps etc. depending on the type of substrate. Flakes with flippers are, however, material-intensive and also complicated to manufacture.

Et skivesystem fra Dynamit Nobel har isolasjonsplater som festes til underlaget med skruer og stålskiver som er belagt med polyvinyl-klorid. Den tettende PVC-folien sveises til de PVC-belagte skivene ved hjelp av varmluft eller på annen måte. Det kan være vanskelig å oppnå en tilfredsstillende befestigelse mellom folie og skive. Hvis denne blir ujevn, kan belastningen på skiven bli skjev. A disc system from Dynamit Nobel has insulation boards that are attached to the substrate with screws and steel discs that are coated with polyvinyl chloride. The sealing PVC foil is welded to the PVC-coated discs using hot air or another method. It can be difficult to achieve a satisfactory attachment between foil and disc. If this becomes uneven, the load on the disc may be skewed.

Et brikkesystem fra Saar Gummiwerk har isolasjonsplatene festetA chip system from Saar Gummiwerk has the insulating plates attached

til underlaget med brikker som skrues fast. I brikkens senter er det en konisk tapp med størst diameter øverst. Folien (kunstgummi) legges over brikken og festes til denne med en "hun-brikke" to the substrate with pieces that are screwed on. In the center of the chip there is a conical pin with the largest diameter at the top. The foil (artificial rubber) is placed over the chip and attached to it with a "female chip"

Et tilsvarende system er kjent fra Gert Deppermann GmbH&Co.,A similar system is known from Gert Deppermann GmbH&Co.,

hvor det finnes en festedel for fastholdelse av isolasjonsplatene. Over festedelen som har en oppadragende bred tapp forsynt med en flens anbringes folien (kunstgummi), en holde-tallerken plasseres over folien og bringes ved hjelp av fottrykk- eller hammerslag i inngrep med flensen og den nevnte oppstående del. Folien blir heller ikke i dette tilfellet perforert. Begge de nevnte systemer er beheftet med den ulempe at befestigelsen skjer ved et lite kontrol-lerbart sneppertinngrep. where there is a fastening part for retaining the insulation boards. The foil (artificial rubber) is placed over the fastening part, which has an upwardly extending wide pin provided with a flange, a holding plate is placed over the foil and brought into engagement with the flange and the aforementioned upright part by means of foot pressure or hammer blows. The foil is also not perforated in this case. Both of the aforementioned systems are affected by the disadvantage that the fastening takes place by means of a little controllable snap action.

Videre er det kjent et brikkesystem fra BST-Byggdetaljer AB. PÅ forkonfeksjonerte flak av PVC-folie settes brikker av haldhård PVC. Som tetting mellom brikker og folie benyttes en spesiell tettepasta, og den samme pasta benyttes som tetting eller forsegling av skruehode.. Brikkene festes til underlaget med skruer. En belastning på brikkene' (f .eks. gangtrafikk) kan resultere i at skruehodet trykkes opp så forseglingen brytes. Furthermore, a chip system is known from BST-Byggdetaler AB. Pieces of hard PVC are placed on prefabricated sheets of PVC foil. A special sealing paste is used to seal between the pieces and foil, and the same paste is used to seal or seal the screw head. The pieces are attached to the substrate with screws. A load on the pieces (e.g. foot traffic) can result in the screw head being pushed up so that the seal is broken.

Dette har man nå søkt å unngå ved å støpe inn en mutter i .brikken, slik at den ligger i plan med brikkens underside og tjener som festepunkt for den spesialskruen systemet er basert i på. En ulempe ved denne utførelsen er risikoen for brudd i brikken på grunn av støpespenninger. Felles for det garrlle og det nye BST-systemet er problemer med tettepastaen samt brudd i de spesialskruer som benyttes This has now been tried to be avoided by molding a nut into the piece, so that it lies flush with the underside of the piece and serves as an attachment point for the special screw on which the system is based. A disadvantage of this design is the risk of breakage in the chip due to casting stresses. Common to the old and new BST systems are problems with the sealing paste and breakage of the special screws used

Ved samtlige kjente systemer benyttes selvborende og selvgjengede skruer for å feste tekkingen til korrugerte stålplater. En generell ulempe ved dette prinsipp er at hver skrue samtidig er en kuldebro. In all known systems, self-drilling and self-tapping screws are used to attach the roofing to corrugated steel sheets. A general disadvantage of this principle is that each screw is also a thermal bridge.

Den foreliggende oppfinnelse med betegnelsen Combi-brikken tar sikte på å tilveiebringe en løsning som overvinner de nevnte problemer. The present invention with the designation Combi chip aims to provide a solution that overcomes the aforementioned problems.

De for oppfinnelsen kjennetegnende trekk vil fremgå av den kjennetegnende del av etterfølgende patentkrav, samt av den etterfølgende beskrivelse under henvisning til vedlagte tegning. The characteristic features of the invention will be apparent from the characterizing part of subsequent patent claims, as well as from the subsequent description with reference to the attached drawing.

På tegningen er vist en folie 1 anbragt på et mellomsjikt av isolas- The drawing shows a foil 1 placed on an intermediate layer of insulating

I jon som hviler på en bærende konstruksjon 4, f.eks. av stålplater, I betong eller treverk. Det kan eventuelt mellom isolasjonslaget<1>2 og den bærende konstruksjonen 4 være anordnet en dampsperre 3, likesom det mellom folien 1 og isolasjonen 2 kan være anordnet en migreringssperre. In ion that rests on a supporting structure 4, e.g. of steel plates, in concrete or wood. A vapor barrier 3 may optionally be arranged between the insulation layer<1>2 and the supporting structure 4, just as a migration barrier may be arranged between the foil 1 and the insulation 2.

Den nevnte folien 1 festes til den bærende konstruksjonen 4 ved hjelp av en kombinert brikke bestående av en underbrikke 5 hvis nedre del 12 er formet som et rør med innsnevring i det nederste partiet 13. Innsnevringen anvendes som festepunkt for festeanordningen. Denne kan være en spiker, skrue for tre, stål, betong e.l., skrue med mutter, bolt, popnagler, ekspansjons-innretninger e.l. The aforementioned foil 1 is attached to the supporting structure 4 by means of a combined chip consisting of a sub-chip 5 whose lower part 12 is shaped like a tube with a narrowing in the lower part 13. The narrowing is used as an attachment point for the fastening device. This can be a nail, screw for wood, steel, concrete etc., screw with nut, bolt, pop rivets, expansion devices etc.

Den nevnte festeanordning er angitt generelt med henvisningstalletThe said fastening device is indicated generally by the reference number

Tappen 14 er ved det nederste partiet forsynt med en spiss 8. Overbrikken har et hode 10 som f.eks. kan være sekskantet beregnet for et dertil egnet monteringsverktøy (ikke vist). Videre kan hodet 10 være forsynt med et skruetrekkerspor 11 for alternativ befestigelse. complementary shape to the lower piece. The upper piece has a lower part. shaped as a threaded pin 14, whose threads cooperate with the threads 6 in the sub-piece. The pin 14 is provided with a point 8 at the bottom part. The upper piece has a head 10 which e.g. can be hexagonal designed for a suitable assembly tool (not shown). Furthermore, the head 10 can be provided with a screwdriver slot 11 for alternative attachment.

Før montering av underbrikken 5, legges det isolerende sjiktet 2 på den bærende konstruksjonen 4, eventuelt etter at dampsperresjiktet Before mounting the sub-piece 5, the insulating layer 2 is placed on the supporting structure 4, possibly after the vapor barrier layer

3 er anbragt oppå den bærende konstruksjonen. Eventuell migreringssperre. 17 legges ut på det isolerende sjiktet 2 før underbrikken 5 3 is placed on top of the supporting structure. Possible migration ban. 17 is laid out on the insulating layer 2 before the sub-chip 5

festes til det bærende underlaget 4 ved hjelp av festeanordningen 9. Det forutsettes selvsagt at det er boret et passende hull i underlaget 4 før festeanordningen anbringes, så fremt ikke festeanordningen er av en selvborende type. ,Det tettende sjiktet av folie 1 is attached to the supporting substrate 4 by means of the fastening device 9. It is of course assumed that a suitable hole has been drilled in the substrate 4 before the fastening device is placed, unless the fastening device is of a self-drilling type. ,The sealing layer of foil 1

blir så lagt over de underliggende sjikt 2, 3 og 17 og underbrikken 5. Overbrikken 7 blir deretter ved hjelp av spissen 8 presset gjennom folien 1 og ved hjelp av gjengene 6 skrudd ned i underbrikken på en slik måte at folien 1 blir presset mellom anleggsflater 15 is then laid over the underlying layers 2, 3 and 17 and the lower piece 5. The upper piece 7 is then pressed through the foil 1 with the help of the tip 8 and screwed down into the lower piece with the help of the threads 6 in such a way that the foil 1 is pressed between contact surfaces 15

De nevnte anr leggsflater 15 og 16 er ifølge oppfinnelsen nedadhellende sett jfra and 16 on the lower piece and the upper piece, respectively, whereby it is effectively sealed against moisture and water in this way. According to the invention, the aforementioned leg surfaces 15 and 16 are viewed downwardly

Claims

! The center axis of the Combi chip. As a result, the foil 1 will also always pour! down from this point. The invention is characterized by simple assembly and is particularly distinguished by the fact that it is not necessary to use sealing paste. Compared to other known systems, the formation of cold bridges is significantly reduced, because most of the Combi chip can be made of low heat-conducting material such as e.g. plastic. The shown attachment device 9, e.g. a self-drilling and self-tapping steel screw, can be locked by bringing the tip 8 of the top piece's pin 14 into contact with the screw head. By letting the under piece have

a tube shape where the lower end 13 can form abutment against the vapor barrier 3, so that a seal is formed around the perforation from the fastening device 9. Furthermore, the system shown provides no opportunities for incorrect perforation of the foil 1 and there is also no risk of leaks at the fastening point due to thickness difference and slips in the intermediate layer 2. As a result of the foil 1 being clamped between the upper and lower piece in the manner shown, load will e.g. pedestrian traffic in the vicinity of the Combi chip does not cause foil 1 to loosen. It will immediately be clear that no leakage will occur even if the fastening device 9 were to detach from the support structure 4. There are also no foreign components in the upper or lower piece that could cause unwanted mechanical stresses and thereby possible breakage. In addition, it is easy to avoid that the pieces hit joints in the intermediate layer 2. The Combi piece allows installation regardless of the weather.
