Opfindelsen angår et fastgørelsesorgan til fastgørelse af pla-5 deformede isoleringselementer til et underlag, for eksempel et tag, og bestående af et første rør, der er indrettet til at strække sig gennem isoleringselementet og indvendigt har gevind eller ringe, og et skiveformet element beregnet til at hvile oven på isoleringen, hvilket skiveformede element sidder 10 for enden af en stang eller et yderligere rør, der udvendigt er forsynet med gevind eller ringe, hvilken stang eller yderligere rør passer ind i det første rør på en sådan måde, at organets længde kan varieres, og hvor der i det første rørs indre ved den bort fra skiven vendende ende er en skrue eller 15 et søm til fastgørelse af organet til den underliggende konstruktion .BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a fastener for securing plate-shaped insulating elements to a substrate, for example a roof, and consisting of a first tube adapted to extend through the insulating element and having internal threads or rings, and a disc-shaped element intended for resting on top of the insulation, which disc-shaped member sits 10 at the end of a rod or additional tube externally provided with threads or rings, which rod or additional tube fits into the first tube in such a way that the length of the member can is varied and where in the interior of the first tube at the end facing away from the disc there is a screw or 15 for attaching the member to the underlying structure.

Opfindelsen er en videreudvikling af fastgørelsesorganet beskrevet og vist i den danske patentansøgning nr. 5091/82.The invention is a further development of the fastener described and shown in Danish patent application no. 5091/82.

20 Når nogen færdes på et tag af den angivne art, består der risiko for, at et stift fastgørelsesorgan af denne art presses igennem tagpappen som følge af, at organet er stift, mens isoleringen er elastisk eftergivende.20 When someone travels on a roof of the specified type, there is a risk that a rigid fastener of this kind will be pushed through the roofing board because the member is rigid while the insulation is resiliently resilient.

Det er ønskeligt helt at eliminere denne risiko ved et fastgørelsesorgan af den nævnte art, og dette formål opnås med et fastgørelsesorgan, som ifølge opfindelsen enten er særegent ved, at det skiveformede element har et rørstykke, der er lej-30 ret aksialt forskydeligt omkring stangen eller det yderligere rør, og at rørstykket samt stangen eller det yderligere rør er forsynet med anslagsorganer, der er indrettet til at kunne hindre, at det skiveformede element kan rykkes ovenud af stangen eller det yderligere rør, eller ved at det indvendige 35 gevind i det første rør er udformet i en løs indsats, der passer ind i røret, og som kan forskydes aksialt deri, og at der er udformet anslagsorganer i indsatsen og røret, der for-It is desirable to completely eliminate this risk by a fastener of the kind mentioned, and this object is achieved by a fastener which according to the invention is either peculiar in that the disc-shaped element has a pipe piece which is mounted axially displaceable about the rod. or the additional pipe, and that the pipe piece and the rod or additional pipe are provided with abutment means adapted to prevent the disc-shaped element from being pulled upwards by the rod or the additional pipe, or by the internal thread in it. first tube is formed in a loose insert which fits into the tube and which can be displaced axially therein, and that abutment means are formed in the insert and the tube which forms

2 hindrer, at indsatsen kan rykkes ovenud. Det skiveformede element vil da følge isoleringens elastiske bevægelser, hvis nogen kommer til at træde på det.2 prevents the insert from being moved upwards. The disc-shaped element will then follow the elastic movement of the insulation, if any will step on it.

5 Ved udførelsesformen angivet i krav 1 er det skiveformede element en separat del, der kan forskydes aksialt i forhold til stangen eller det yderligere rør, der kan skrues ned i det første rør, der bærer skruen eller sømmet. Ifølge udformningen i krav 2 er der en aksial forskydelig indsats med gevind i det 10 første rør.In the embodiment of claim 1, the disc-shaped member is a separate member which can be displaced axially with respect to the rod or additional tube which can be screwed down into the first tube carrying the screw or seam. According to the embodiment of claim 2, there is an axially displaceable insert with threads in the first tube.

Ved nævnte færdsel består der også risiko for, at fastgørelsesorganets længde ændres ved, at det skiveformede element drejes om dets længdeakse, så dette skrues enten ud eller ind 15 i det første rør. Denne risiko imødegås, når fastgørelsesorganet udformes som angivet i krav 3-4, ifølge hvilke anslagene mellem de forskydelige dele kan være udformet således, at de ikke kan dreje sig i forhold til hinanden.At said traffic there is also a risk that the length of the fastening means is changed by rotating the disc-shaped element about its longitudinal axis so that it is either screwed out or inserted into the first tube. This risk is counteracted when the fastener is designed as claimed in claims 3-4, according to which the stops between the slidable parts can be designed so that they cannot rotate relative to each other.

20 I det følgende forklares fastgørelsesorganet ifølge opfindelsen nærmere under henvisning til tegningen, hvor: fig. i viser et tværsnit gennem en første udførelsesform for et kendt fastgørelsesorgan, 25 fig. 2 viser det i fig. 1 afbildede fastgørelsesorgan set direkte fra oven, fig. 3 viser en anden udførelsesform for et kendt fastgørel- 30 sesorgan med prægninger på den cirkulære skives un derside, fig. 4 viser fastgørelsesorganet i fig. 3 fra undersiden, 35 fig. 5 viser en første udførelsesform af et fastgørelsesorgan ifølge opfindelsen,20 In the following, the fastener according to the invention is explained in more detail with reference to the drawing, in which: FIG. 1 is a cross-section through a first embodiment of a known fastener; FIG. 2 shows that in FIG. 1 is a top view of the fastener shown in FIG. 3 shows another embodiment of a known fastener with embossings on the underside of the circular disc; FIG. 4 shows the fastener of FIG. 3 from below, FIG. 5 shows a first embodiment of a fastener according to the invention,

fig. 6 viser et tværsnit for enden af rørstykket ved den cirkulære skive af en modificeret udførelsesform af fastgørelsesorganet i fig. 5, og 5 fig. 7 viser et længdesnit gennem den øverste del af røret med skruen i endnu en udførelsesform af organet ifølge opfindelsen.FIG. 6 is a cross-sectional view of the end of the tube at the circular disc of a modified embodiment of the fastener of FIG. 5 and 5 in FIG. 7 shows a longitudinal section through the upper part of the tube with the screw in yet another embodiment of the device according to the invention.

Fastgørelsesorganet - i praksis benævnt "tagdækkersøm" vist på 10 tegningen består af et første rør 1 forsynet med indvendigt gevind 2. I den ene ende af røret er der en forlængelse 3 til beskyttelse af en skrue 4 eller et søm indført i røret. Desuden er der et andet rørstykke 5, der bærer en cirkulær skive 6 på den ene ende, og som er forsynet med udvendigt gevind 7, 15 så det kan skrues mere eller mindre ind i det første rørstykke, hvorved man kan tilpasse længden af fastgørelsesorganet til den aktuelle tykkelse på isoleringen.The fastener - in practice referred to as the "roofing seam" shown in the drawing, consists of a first tube 1 provided with an internal thread 2. At one end of the tube there is an extension 3 for protecting a screw 4 or a seam inserted into the tube. In addition, there is a second pipe piece 5 which carries a circular disc 6 on one end and which is provided with external thread 7, 15 so that it can be screwed more or less into the first pipe piece, whereby the length of the fastening means can be adjusted to the actual thickness of the insulation.

I skiven 6 er der to udsparinger 8, der dels tjener som fin-20 gergreb til at skrue skiven op og ned, dels tjener til at fastlåse den, idet bitumen ved udlægning af tagpap som tækkemateriale vil trænge ned i udsparingerne og dermed fastlåse skiven mod drejning.In the washer 6, there are two recesses 8, which serve partly as a fine grip for screwing the washer up and down and partly for locking it, since bitumen when laying roofing paper as a covering material will penetrate the recesses and thus lock the washer against rotation.

25 Ved fastgørelse af fastgørelsesorganet skæres forlængelsen 3 af med en kniv, så skruen 4 eller sømmet bliver fri. Af transportmæssige og opbevaringsmæssige grunde er skiven skruet ind i dens inderste stilling som antydet med stiplede linier i fig. 1 for at optage mindst muligt volumen. Fra dens inderste 30 stilling skrues skiven ud til en stilling lidt over isoleringstykkelsen, hvorefter fastgørelsesorganet stikkes gennem isoleringen og fastgøres med en skruetrækker henholdsvis dorn, der stikkes ned gennem rørene til inddrivning af skruen eller stålsømmet i den underliggende konstruktion. Fastgørelsen af-35 sluttes med, at skiven spændes let mod isoleringen.25 When attaching the fastener, the extension 3 is cut off with a knife so that the screw 4 or the nail is released. For transport and storage reasons, the disc is screwed into its innermost position as indicated by dotted lines in FIG. 1 to record the minimum volume possible. From its innermost position, the washer is unscrewed to a position slightly above the insulation thickness, after which the fastener is inserted through the insulation and secured with a screwdriver or mandrel, respectively, which is inserted through the tubes to drive the screw or steel seam into the underlying structure. The fastening is completed by slightly tightening the disc against the insulation.

med skiven 6 skrues tilbage efter tilspændingen ud over den sikkerhed, som de to huller giver, er der på undersiden af skiven i udførelsesformen vist i fig. 3 og 4 to modstående fremspring 9 lavet som et cirkeludsnit med et trekantet tvær-5 snit med en lodret kant 10 og skrå flade 11. Der er ingen modstand mod iskruningen, men den lodrette kant vil forhindre en utilsigtet tilbageskruning, idet fibermaterialet vil fjedre tilbage op mod skivens underside.with the washer 6 being screwed back after tightening in addition to the safety provided by the two holes, there is shown on the underside of the washer in the embodiment shown in fig. 3 and 4 are two opposite projections 9 made as a circular section with a triangular cross-section with a vertical edge 10 and inclined surface 11. There is no resistance to the ice curvature, but the vertical edge will prevent an unintended backward screwing as the fiber material will spring back up against the underside of the disc.

10 På tegningens fig. 5 er der vist en udførelsesform for fastgørelsesorganet ifølge opfindelsen, hvor den cirkulære skive 6 er aksialt forskydelig i fastgørelsesorganets længderetning.10 In the drawing FIG. 5, an embodiment of the fastener according to the invention is shown in which the circular disc 6 is axially displaceable in the longitudinal direction of the fastener.

Der er i figuren benyttet samme henvisningsbetegnelser som i det foregående for samme dele. Den cirkulære skive 6 er her 15 forsynet med et kort rørstykke 12, der forneden er forsynet med en ind i røret vendende anslagsring 13. Rørstykket 12 passer ned over røret 5, som foroven har en anslagsring 14, der samvirker med rørstykkets anslagsring 13. Anslagsringens anlægsflade er skrånende ud fra røret og nedefter, hvilket sik-20 rer mod en utilsigtet løsgørelse af delene fra hinanden. Friktionen mellem de to anlægsflader kan være tilstrækkelig til at sikre en iskruning af den cirkulære plade 6.The same reference numerals as in the foregoing are used for the same parts in the figure. Here, the circular disc 6 is provided with a short pipe piece 12, which is provided at the bottom with an abutment ring 13 which faces into the pipe. The pipe piece 12 fits down over the pipe 5, which has an abutment ring 14 at the top which cooperates with the abutment ring 13 of the abutment ring. abutment surface is sloped from the pipe downwards, which ensures an unintentional release of the parts from each other. The friction between the two abutment surfaces may be sufficient to ensure an ice screwing of the circular plate 6.

På fig. 6 er der vist en lidt anden udførelsesform end den i 25 fig. 5, idet anlægsringen øverst på røret er udført som fire ribber 15, der passer ind i dertil svarende indhak i en ring nederst på rørstykket 12. Derved sikres, at de to dele er rotationsfast forbundet med hinanden.In FIG. 6 shows a slightly different embodiment than that of FIG. 5, the abutment ring at the top of the pipe being made as four ribs 15 which fit into corresponding notches in a ring at the bottom of the pipe piece 12. This ensures that the two parts are rotationally connected to each other.

30 I eksemplerne vist i fig. 1-4 er der indvendigt gevind 2 i hele rørets længde 1. Dette er imidlertid ikke nødvendigt. Gevindstykket skal blot være så langt, at det kan overføre det træk, der kommer som følge af sug på tagfladen, når det blæser.In the examples shown in FIG. 1-4 there are internal threads 2 throughout the length of the tube 1. However, this is not necessary. The threaded piece should only be so far that it can transmit the tension resulting from suction on the roof surface as it blows.

For at sikre, at de to dele er skruet tilstrækkeligt sammen, kan den bort fra den cirkulære skive 6 vendende ende af det 35In order to ensure that the two parts are screwed together sufficiently, it can move away from the circular disc 6 facing the end of it.

yderligere rør 5 være opslidset 16. Opslidsningen vil yde modstand, når den skrues op i det indvendige gevindstykke 2 og derved virker som indikator for, at delene 1, 5 skrues for langt fra hinanden.further tube 5 may be slit 16. The slit will provide resistance as it is screwed up into the inner thread piece 2, thereby acting as an indicator that the parts 1, 5 are screwed too far apart.

5 På tegningens fig. 7 er antydet en anden udførelsesform, hvor det cirkulære skiveformede hoved 6 kan forskydes aksialt. Røret 1 er her forsynet med en løs rørformet indsats 17 med indvendigt gevind 2. Indsatsen fastholdes mod udrykning og 10 drejning i røret 1 med fjedrende flige med modhager 18, der griber ind i dermed overensstemmende slidser 19 i røret 1. Indsatsen og dermed det cirkulære hoved 6 kan således forskydes aksialt i røret. Modhagernes 18 antal afhænger af deres størrelse og de kræfter, der skal overføres og med hensyn til 15 placeringen kan de anbringes forskudt, hvis de af pladshensyn, når indsatsen sættes ned i røret, ikke kan anbringes over for hinanden.5 In the drawing FIG. 7 is another embodiment, in which the circular disc-shaped head 6 can be displaced axially. The tube 1 is here provided with a loose tubular insert 17 with an internal thread 2. The insert is held against the extension and 10 rotation in the tube 1 with resilient tabs with barbs 18, which engage in corresponding slots 19 in the tube 1. The insert and thus the circular head 6 can thus be displaced axially in the tube. The number of barbs 18 depends on their size and the forces to be transferred and with respect to the placement they can be staggered if, for reasons of space, when the insert is inserted into the tube, they cannot be placed opposite each other.

I de netop beskrevne udførelsesformer er rørene forsynet med 20 gevind, men kan lige så vel udføres med ringformede vulster.In the embodiments just described, the tubes are provided with 20 threads, but may as well be made with annular beads.

Selv om opfindelsen her er beskrevet specielt i relation til tage, kan den også benyttes ved opsætning af isolering på vægge og lofter.Although the invention has been described specifically in relation to roofs, it can also be used in the installation of insulation on walls and ceilings.
