Description

Foreliggende oppfinnelse angår en profilplate bestående av bærende og romavsluttende avsnitt. The present invention relates to a profile plate consisting of supporting and space-closing sections.

Fra publikasjonen "Dach und Vand", Planen und Bauen mit Aluminiumtafeln, 1982, s.126, er det kjent ved takkonstruk-sjoner å sette aluminiumsprofilplater på ståltrapesprofiler. From the publication "Dach und Vand", Planen und Bauen mit Aluminiumtafeln, 1982, p.126, it is known for roof constructions to put aluminum profile plates on steel trapezoidal profiles.

For veggkonstruksjoner har det vært benyttet en lignende løsning der aluminiumsprofilplatene er montert på kassetter. Disse er fremstilt av stål og i tillegg utstyrt med en varmeisolasjon på kassettsidene. For wall constructions, a similar solution has been used where the aluminum profile plates are mounted on cassettes. These are made of steel and additionally equipped with thermal insulation on the cassette sides.

I branntilfelle skjermer stålkassettene aluminiumsprofilplatene mot varmen. Den herskende temperaturen er så høy at stålbærerne i en fagverkskonstruksjon resp. stålåsene på taket smelter. In the event of a fire, the steel cassettes shield the aluminum profile plates from the heat. The prevailing temperature is so high that the steel beams in a truss construction resp. the deadbolts on the roof are melting.

Foreliggende oppfinnelse går ut på å forhindre at det oppstår høye temperaturer i branntilfeller, og derved beholde bæreevnen for tak resp. veggkonstruksjonen ved høyest mulige temperaturområder. The present invention aims to prevent high temperatures from occurring in the event of a fire, thereby maintaining the load-bearing capacity of the roof or the wall construction at the highest possible temperature ranges.

Dette oppnås ved hjelp av de trekk som fremgår av patent-kravene. This is achieved with the help of the features that appear in the patent claims.

Det har vist seg at ved vekksmelting av de romavsluttende avsnittene oppstår det store åpninger gjennom hvilke det skjer et raskt varmeavtrekk. Derved kan de bærende elementene av høyvarmefast legering i stor utstrekning beholde sin stabilitet, da det ikke oppstår så høy temperatur at grensetemperaturen for instabilitet overskrides. It has been shown that when the sections that close the space are melted away, large openings occur through which a rapid heat extraction takes place. Thereby, the load-bearing elements of high heat-resistant alloy can largely retain their stability, as such a high temperature does not occur that the limit temperature for instability is exceeded.

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

fig. 1 viser en kassettformet profilplate for tak— og vegginnerkledning, og fig. 1 shows a cassette-shaped profile plate for roof and wall cladding, and

fig. 2 viser en profilplate med et bærende avsnitt av en høyt varmefast aluminiumslegering. fig. 2 shows a profile plate with a supporting section of a highly heat-resistant aluminum alloy.

I fig. 1 er de bærende avsnittende betegnet med la og lb og det romavsluttende avsnittet med 2. Avsnittene er forbundet mekanisk med hverandre ved hjelp av falsforbindelser 3,4. I foreliggende tilfelle er de bærende avsnittene av stål og det romavsluttende avsnittet fremstilt av aluminium. In fig. 1, the load-bearing section ends are denoted by la and lb and the space-closing section by 2. The sections are connected mechanically to each other by means of seam joints 3,4. In the present case, the load-bearing sections are made of steel and the space-closing section is made of aluminium.

I fig. 2 er det for de bærende avsnittene benyttet en ekstrudert aluminiumsprofil 5,6 og for de romavsluttende avsnittene en ribbet profilplate av aluminium. Forbindelsen mellom de bærende og de romavsluttende avsnittene er tilveiebragt ved hjelp av liming. In fig. 2, an extruded aluminum profile 5,6 has been used for the load-bearing sections and a ribbed aluminum profile plate for the room-closing sections. The connection between the load-bearing and the room-closing sections is provided by means of gluing.
