Description

Fuge mellom brann- og trykksikre vegg- og takelementer. Joint between fire- and pressure-resistant wall and ceiling elements.

Foreliggende oppfinnelse vedrører en ny og forbedret ut-førelse av en fuge mellom brann-, og trykksikre vegg- og takelementer for aggregatrom for vifter og lignende, hvilke elementer består av rektangulære platehylstere som inneslutter et brannsikkert, varme- og lydisolerende fyllmateriale og langs to motstående lengdesidekanter er utformet med U-formede spor og føyet sammen ved hjelp av to U-formede klemlistprofiler, hvis ben er bokket om til anleggsflater og holdes trykket mot sporenes bunn av et antall skruer. The present invention relates to a new and improved design of a joint between fire-proof and pressure-proof wall and ceiling elements for aggregate rooms for fans and the like, which elements consist of rectangular sheet casings that enclose a fire-proof, heat- and sound-insulating filling material and along two opposite longitudinal side edges are designed with U-shaped grooves and joined together by means of two U-shaped clamping strip profiles, the legs of which are bent into contact surfaces and are held pressed against the bottom of the grooves by a number of screws.

I svensk utlegningsskrift 312 217 er beskrevet en anord-ning for sammenføyning av brann- og trykksikre elementer for kon-struksjon av aggregatrom for vifter og lignende. Vegger og tak består av et antall elementer som føyes sammen ved hjelp av mot veggens eller takets inn- og utsider hvilende U-formede klemlistprofiler som parvis klemmes mot langsgående spor i elementenes sammenstøtende kanter ved hjelp av spesielt utformede, gjennomgående bolter og derved danner en pålitelig, brann- og trykksikker fuge mellom elementene. In Swedish design document 312 217, a device for joining fire- and pressure-proof elements for the construction of aggregate rooms for fans and the like is described. Walls and roofs consist of a number of elements that are joined together by means of U-shaped clamping strip profiles resting against the inside and outside of the wall or roof, which are clamped in pairs against longitudinal grooves in the elements' clashing edges with the help of specially designed through-bolts and thereby form a reliable , fire and pressure-proof joint between the elements.

Den spesielle utforming av boltene består i at den indre del av bolthodet har et kvadratisk parti som passer inn i tilsvar-ende kvadratiske hull i klemlistene og som hindrer at bolten dreier seg ved påskruingen av mutteren under montasjen. Den spesielle form av bolten medfører en ikke uvesentlig fordyrelse av fugen. Det samme gjelder for de kvadratiske hull i klemlistene. The special design of the bolts consists in the fact that the inner part of the bolt head has a square section which fits into corresponding square holes in the clamping strips and which prevents the bolt from turning when the nut is screwed on during assembly. The special shape of the bolt results in a not insignificant increase in the cost of the joint. The same applies to the square holes in the clamp strips.

En annen ulempe ved de gjennomgående bolter består i at de må træs inn i klemlistenes hull utenfra, hvilket dels krever plass utenfor veggen eller taket og dels krever to menns samarbeide under montasjen. Another disadvantage of the through-bolts is that they have to be threaded into the clamp strips' holes from the outside, which partly requires space outside the wall or ceiling and partly requires the cooperation of two men during assembly.

Ifølge oppfinnelsen unngås de nevnte ulemper ved at bolten er T-formet og med sitt hode innvendig griper om den ytre klemlist i stedet for utvendig, og ved at hodet er noe for stort til å kunne dreies rundt i klemlisten. Noe hull behøver der altså ikke utføres i denne og bolten kan av én mann bringes på plass fra innsiden av veggen eller taket under montasjen. For å gjøre fugen enda billigere er skruen utført som en flat skrue som stanses ut av platemateriale med gjengene formet som tenner med gangprofil langs langsidene. According to the invention, the aforementioned disadvantages are avoided by the fact that the bolt is T-shaped and with its head grips the outer clamping strip on the inside instead of the outside, and by the head being somewhat too large to be able to be turned around in the clamping strip. There is therefore no need to make any holes in this and the bolt can be brought into place by one man from the inside of the wall or ceiling during assembly. To make the joint even cheaper, the screw is made as a flat screw that is punched out of plate material with the threads shaped like teeth with a walking profile along the long sides.

Oppfinnelsen skal beskrives under henvisning til tegningen som viser i snitt en fuge mellom to elementer. På tegningen angir 1 et rektangulært platehylster som har visse standardiserte dimensjoner og inneslutter et varme- og lydisolercnde, brannsikkert fyllmateriale 2. Platehylsteret med fyllmateriale utgjør et vegg-eller takelement som føyes sammen med lignende elementer til hele tak og vegger. For sammenføyningen er elementets platehylster utformet med U-formede spor 3. Elementene holdes sammen av klemlistprofiler 4 som med sine ombøyde kanter 5 ligger an mot sporenes 3 bunn. Profilene 4 klemmes mot sporbunnene 3 av skruer 6 som er stanset ut av platemateriale og som dreiet 90° til papirets plan føres inn fra veggens innerside - på tegningen nedenfra - før an-bringelsen av den indre klemlist. For tetning av fugen er inner-bunnen belagt med et tetningsmateriale 7. The invention shall be described with reference to the drawing which shows a joint in section between two elements. In the drawing, 1 indicates a rectangular sheet casing which has certain standardized dimensions and encloses a heat- and sound-insulating, fire-proof filling material 2. The sheet casing with filling material forms a wall or roof element which is joined together with similar elements to the entire ceiling and walls. For joining, the element's sheet sleeve is designed with U-shaped grooves 3. The elements are held together by clamping strip profiles 4 which, with their bent edges 5, rest against the bottom of the grooves 3. The profiles 4 are clamped against the track bottoms 3 by screws 6 which are punched out of sheet material and which, turned 90° to the plane of the paper, are inserted from the inside of the wall - in the drawing from below - before the application of the inner clamping strip. To seal the joint, the inner bottom is coated with a sealing material 7.

Skruens 6 hode 8 er utformet med føtter 9 som innenfra støter mot den ytre - på tegningen øvre - klemlist på dennes ombøy-de kanter 5. Trykket fra klemlistene 4 mot sporenes 3 bunn regu-leres til passende verdi ved hjelp av mutteren 10 som låses ved at skruens frie ende 11 bøyes omtrent vinkelrett til skruens lengderetning . The head 8 of the screw 6 is designed with feet 9 that abut from the inside against the outer - in the drawing upper - clamping strip on its bent edges 5. The pressure from the clamping strips 4 against the bottom of the grooves 3 is regulated to a suitable value by means of the nut 10 which is locked in that the screw's free end 11 is bent roughly perpendicular to the screw's longitudinal direction.

Hodet 8 er noe bredere enn klemlisten 4 innvendig, således at det under montasjen hindres i å dreie seg. I ferdig til-stand vil det altså stå noe skrått, som antydet på tegningen ved de dobbelte konturer. Ved tiltrekningen av mutteren trenges der altså intet mothold på skruen. Da skruen anbringes på plass innenfra, kreves der ikke noe rom utenfor eller over den ytre list 4, således at en eneste person kan utføre montasjen. The head 8 is somewhat wider than the clamping strip 4 on the inside, so that it is prevented from turning during assembly. In the finished state, it will therefore be somewhat slanted, as indicated in the drawing by the double contours. When tightening the nut, no resistance is needed on the screw. As the screw is placed in place from the inside, no space is required outside or above the outer strip 4, so that a single person can carry out the assembly.
