Description

Foreliggende oppfinnelse angår en anordning ved shingelelement for taktekking, der det på elementets overside er anordnet klebefelter for feste av ovenpåliggende elements tunger, og-der baksiden er forsynt med et kontinuerlig klebefelt som dekker hele det feltet som ligger bak tungene, hvilket felt er dekket med en folie for å forhindre sammenklebing av de enkelte elementene i en stabel. The present invention relates to a device for shingle elements for roofing, where adhesive fields are arranged on the upper side of the element for attaching the tongues of the overlying element, and where the back is provided with a continuous adhesive field that covers the entire field behind the tongues, which field is covered with a foil to prevent the individual elements in a stack from sticking together.

De første shingeltypene som ble produsert var helt uten klebefelt. De første shingelelementer med klebefelt hadde klebefelt under tungene og på oversiden av den såkalte ryggen, dvs. det feltet som ligger innenfor tungene. Folien ble fjernet under tekkingen. Med tiden klebet solvarmen ned shingéltungene slik at de ikke kunne blåse opp, og det ble dannet en asfalt mot asfalt sammenklebing langs shingelplatens bakkant som hindret vanninntrengning. Dette systemet er patentert. Systemet var meget godt sett fra et taktekkings-synspunkt, men var noe brysomt å legge på grunn av de relativt store plastremsene som skulle trekkes av. The first types of shingles that were produced were completely without adhesive strips. The first shingle elements with adhesive strips had adhesive strips under the tongues and on the upper side of the so-called ridge, i.e. the field that lies inside the tongues. The foil was removed during the covering. Over time, the sun's heat glued down the shingle tongues so that they could not inflate, and an asphalt-to-asphalt joint was formed along the back edge of the shingle sheet that prevented water ingress. This system is patented. The system was very good from a roofing point of view, but was somewhat troublesome to install because of the relatively large plastic strips that had to be pulled off.

Noe senere ble det markedsført en type shingel uten folieavriving og med alle klebefeltene samlet på shingelens overside. Klebefeltene festet tungene, men hindret bare i liten grad vanninntrengning over shingelens rygg. Klebefeltene ble aktivert av solvarme som tidligere, men var forbedret ved at; klebemiddelet ga et -visst feste ved nedtråkking av tungene på sommertiden. pette kalles varme- og trykkfølsomt klebemiddel. Som klebemiddel brukes normalt asfalt. For å hindre sammenklebing i pakkene var det på baksiden av hvert element lagt en såkalt slippfolie. Dette var en teknikk som var kjent i USAi Denne shingeltypen har den fordel at elementene er meget godt beskyttet mot sammenklebing i pakkene og er rask å legge. Ulempen er selvfølgelig at det ikke er noe vern mot vanninn-^. trenging over elementenes rygg. I normalt klima er dette ikke noen ulempe, men i værharde distrikter med slagregn vil vann kunne trenge inn over ryggen på elementene og lekke ned i tak-konstruksjonen. Dette vil også kunne skje dersom man har dårlig lufting under taket. Det kan da bygge seg opp en is-barriere langs takkanten. Bak denne kan det ved smelting legge seg en vannpytt, som har mulighet for å!trenge inn under shingellagene. Somewhat later, a type of shingle without foil tear-off and with all the adhesive strips gathered on the upper side of the shingle was marketed. The adhesive strips attached the tongues, but only slightly prevented water ingress over the back of the shingle. The adhesive fields were activated by solar heat as before, but were improved in that; the adhesive gave a -certain hold when the tongues were stepped on in the summertime. pette is called a heat- and pressure-sensitive adhesive. As an adhesive, asphalt is normally used. To prevent sticking together in the packages, a so-called release foil was placed on the back of each element. This was a technique that was known in the USAi This type of shingle has the advantage that the elements are very well protected against sticking together in the packages and is quick to lay. The disadvantage is, of course, that there is no protection against water ingress. penetration over the back of the elements. In a normal climate this is not a disadvantage, but in hard-weather districts with torrential rain, water will be able to penetrate over the back of the elements and leak into the roof structure. This can also happen if there is poor ventilation under the roof. An ice barrier can then build up along the edge of the roof. Behind this, when melting, a puddle of water can form, which has the opportunity to!penetrate under the shingle layers.

Hensikten med foreliggende oppfinnelse er å frem-skaffe et shingelelement som er godt beskyttet mot sammenklebing i stabel, er rask å legge i normalt klima og som i slagregnsdistrikter kan tettes mot inntrengning av vann over shingelryggen. The purpose of the present invention is to provide a shingle element which is well protected against sticking together in a stack, is quick to lay in a normal climate and which in torrential rain districts can be sealed against ingress of water over the shingle ridge.

Dette oppnås ifølge oppfinnelsen ved et shingelelement av den innledningsvis nevnte art som erkarakterisertved a£vfolien er splittet på langs av shingelelementet til to strimler, av hvilke i det minste den foliestrimmel som ligger nærmest tungene er en avrivningsfolie, og at det på oversiden av shingelelementet er anordnet et kontinuerlig klebefelt ved elementets bakkant. This is achieved according to the invention by a shingle element of the type mentioned at the outset, which is characterized by the foil being split lengthwise by the shingle element into two strips, of which at least the foil strip closest to the tongues is a tear-off foil, and that on the upper side of the shingle element is arranged a continuous adhesive field at the rear edge of the element.

Ved en hensiktsmessig utførelsesform overlapperIn a suitable embodiment overlaps

de to foliestrimlene hverandre ved de sammenfallende lengdekantene. the two foil strips to each other at the coincident longitudinal edges.

En fordelaktig utførelsesform for oppfinnelsen erkarakterisert vedat klebefeltet ved shingelelementets bakkant består*av varmefølsomt klebemiddel, mens klebefeltene for tungene er både varme- og trykkfølsomme. An advantageous embodiment of the invention is characterized by the fact that the adhesive field at the rear edge of the shingle element consists* of heat-sensitive adhesive, while the adhesive fields for the tongues are both heat- and pressure-sensitive.

En produksjonsvennlig utførelsesform erkarakterisert vedat klebefeltet ved bakkanten og klebefeltene for tungene går over i hverandre,- slik,at det dannes et felles klebefelt med tannet kant. A production-friendly embodiment is characterized by the fact that the adhesive field at the rear edge and the adhesive fields for the tongues merge into each other, so that a common adhesive field with a serrated edge is formed.

Oppfinnelsen skal i det følgende forklares nærmere under henvisning til tegningen, der The invention will be explained in more detail below with reference to the drawing, where

figur 1 viser shingelelementet ifølge oppfinnelsen sett ovenfra, figure 1 shows the shingle element according to the invention seen from above,

figur 2 viser shingelelementet sett nedenfra, figure 2 shows the shingle element seen from below,

figur 4 viser shingelelementer ifølge oppfinnelsen lagt på en andre måte. figure 4 shows shingle elements according to the invention laid in a different way.

Shingelelementet 1 består på vanlig måte av en såkalt rygg 2 samt tunger 3. Langs bakkanten 4 av ryggen 2 er det på shingelelementets overside anordnet et sammenhengende klebefelt 5 av. varmefølsom asfalt. På det sted der endene av tungene på ovenpåliggende element blir plassert, er det anordnet klebefelt 6 som består av varme- og trykkfølsom asfalt. Tungenes overside og den delen av ryggen som blir synlig på The shingle element 1 normally consists of a so-called ridge 2 and tongues 3. Along the rear edge 4 of the ridge 2, a continuous adhesive strip 5 is arranged on the upper side of the shingle element. heat-sensitive asphalt. At the place where the ends of the tongues of the overlying element are placed, there is an adhesive strip 6 which consists of heat- and pressure-sensitive asphalt. The upper side of the tongue and the visible part of the back

langsgående limfelt J, som er dekket med en plastfolie, som er delt .i to strimler 8 og 9. Strimlene har en slik bredde at de overlapper hverandre ved en midtre overlapping 10. Som det vil fremgå av det ovenstående og som også synes klart på tegningen, vil foliestrimlene 8 og 9 fullstendig dekke lim-feltene 5 og 6 når shingelelementer stables på hverandre med det eiie shingelelements underside mot det nedenforliggende shingelelements overside. Det blir således ingen sammenklebing i pakken. longitudinal adhesive field J, which is covered with a plastic foil, which is divided into two strips 8 and 9. The strips have such a width that they overlap each other at a middle overlap 10. As will be apparent from the above and which is also clearly visible on drawing, the foil strips 8 and 9 will completely cover the glue fields 5 and 6 when shingle elements are stacked on top of each other with the underside of the own shingle element against the upper side of the underlying shingle element. There will therefore be no sticking together in the package.

Dersom shingelelementer ifølge oppfinnelsen skal legges i et ikke værhardt distrikt, plasseres et shingelelement 1 oppå en ferdig lagt rekke med shingelelementer uten at strimlene 8 og- 9 fjernes. Shingeltungene 3 vil komme over klebefeltene 6 med varme- og trykkfølsom asfalt, og vil bli klebet fast slik at det forhindres at tungene blåser opp. If shingle elements according to the invention are to be laid in a non-weatherproof district, a shingle element 1 is placed on top of a ready-laid row of shingle elements without removing the strips 8 and 9. The shingle tongues 3 will come over the adhesive fields 6 with heat- and pressure-sensitive asphalt, and will be glued firmly so that the tongues are prevented from blowing up.

Dersom det skal legges shingel på et tak i et slagregnsdistrikt, fjernes strimmelen 9 før shingelelementet 1 legges opp på en tidligere-lagt- rad av shingelelementer. Den nedre delen a\£ klebefeltet 7 p'å shingelelementets 1 bakside vil da bli -liggende mot limfeltet 5 på de nedenforliggende shingelelementenes overside, og en får en tett forsegling ved en shingelrads bakkant, som vil forhindre vanninntrengning. ; If shingles are to be laid on a roof in a driving rain district, the strip 9 is removed before the shingle element 1 is laid on top of a previously laid row of shingle elements. The lower part of the adhesive field 7 on the back side of the shingle element 1 will then lie against the glue field 5 on the upper side of the shingle elements below, and a tight seal is obtained at the back edge of a row of shingles, which will prevent water ingress. ;

Man vil således kunne foreta en arbeidsbesparende taktekking i distrikter uten slagregn, ved at strimlene 8 og 9 beholdes på baksiden av strimmelelementene. I slagregnsdistrikter kan man få en fullstendig tetting av shingelbelegget ved at en smal. strimmel 9 trekkes av og man får en forsegling av taket asfalt mot asfalt. It will thus be possible to carry out labour-saving roofing in districts without torrential rain, by keeping the strips 8 and 9 on the back of the strip elements. In areas with heavy rain, the shingle covering can be completely sealed by a narrow strip 9 is pulled off and you get a seal of the roof asphalt against asphalt.
