GLASRUDEENHED TIL INDSÆTTELSE I EN FLADE ELLER RAMME SÅSOM ET SKIBSSKODGLASS PANEL FOR INSTALLATION IN A FLAT OR FRAME LIKE A SHIP CODE

5 Teknikkens standpunkt.5 State of the art.

Frembringelsen angår en glasrudeenhed, eksempelvis et vindue eller en dør, til indsættelse i en flade eller ramme, hvilken glasrudeenhed består af mindst ét sædvanligt yderligt placeret bæreglaslag bestående af mindst ét bæreglas, 10 et mellemglaslag betående af mindst ét mellemglas og et yderligt placeret frontglaslag bestående af mindst ét frontglas, hvilken glasrudeenhed er samlet ved hjælp af af-standsstykker.The invention relates to a glass pane unit, for example a window or door, for insertion into a surface or frame, which glass pane unit consists of at least one usual outer positioned carrier layer consisting of at least one carrier glass, an intermediate layer consisting of at least one intermediate glass and a further positioned front glass layer comprising of at least one front glass, which glass window unit is assembled by means of spacers.

15 En glasrudeenhed af denne art, udformet eksempelvis som et vindue eller en dør, har sædvanligvis flere funktioner, nemlig at tillade lysgennemgang, at sikre udsyn samt at isolere. For glasrudeenheder til anvendelse til eksempelvis skibsbrug, stilles der endvidere høje krav til sikkerheden 20 mod brand og røggennemtrængen. I tilfælde af brand skal en glasrudeenhed således forblive ubrudt i en sådan grad, at såvel røgudvikling som selve ilden gennem enheden forhindres. Imidlertid er det vanskeligt at opnå en tilstrækkelig sikring, da det nemt vil være i modstrid med glasrudeenhe-25 dens øvrige funktioner.15 A glass pane unit of this kind, designed, for example, as a window or door, usually has several functions, namely to allow light transmission, to ensure visibility and to insulate. In addition, for glass pane units for use for, for example, ship use, high safety requirements 20 against fire and smoke penetration are set. In the event of a fire, a glass pane unit must thus remain unbroken to such an extent as to prevent both smoke generation and the fire itself through the unit. However, it is difficult to obtain sufficient fuse as it will easily conflict with the other functions of the glass pane.

Hidtil kendte glasrudeenheder har ikke kunnet opfylde alle disse krav på en tilfredsstillende måde.Previously known glazing units have not been able to meet all these requirements satisfactorily.

30 Fordele ved frembringelsen30 Advantages of Generation

Ved at opbygge glasrudeenheden ifølge frembringelsen således, at mellemglaslaget består af varmestrålingsdæmpende glas, og frontglaslaget består af varmeresistent glas med høj viskositet og lille udvidelseskoefficient, opnås såle-35 des, at frontglaslaget, der vender mod en eventuel brandudbredelse, ikke brydes, idet glasset har en meget lille ud- 2 DK 93 00557 U3 videlseskoefficient og høj viskositet ved de aktuelle temperaturer. Ved hjælp af mellemglaslaget og mellemrummene opnås yderligere at strålingsvarmen reduceres så meget, at temperaturgradienten ved bæreglaslaget ikke overstiger en given temperatur. Således opnås ifølge frembringelsen, at bæreglaslaget, der er dimensioneret i overensstemmelse med sædvanlige kendte kriterier, forbliver intakt og forhindrer gennemtrængning af røg og flammer ved evt. brand.By constructing the glass pane unit according to the invention so that the intermediate glass layer consists of heat radiation damping glass and the front glass layer consists of heat-resistant glass with high viscosity and a small coefficient of expansion, so that the front glass layer facing a possible fire propagation is not broken, as the glass has a very low coefficient of viscosity and high viscosity at the actual temperatures. By means of the intermediate glass layer and the spaces, it is further obtained that the radiant heat is reduced so much that the temperature gradient at the carrier glass layer does not exceed a given temperature. Thus, according to the invention, the carrier glass layer, which is dimensioned in accordance with usual known criteria, is achieved to remain intact and prevents the penetration of smoke and flames by any means. fire.

Ved, som omhandlet i krav 2, at anvende kalksilikatglas i mellemglaslaget og borsilikatglas i frontglaslaget, opnås en sikker og solid udførelse ved hjælp af sædvanlige materialer, der kan dimensioneres efter de nødvendige styrke og sikkerhedskrav.By using lime silicate glass in the intermediate glass layer and borosilicate glass in the front glass layer, as described in claim 2, a safe and solid construction is achieved by using ordinary materials which can be dimensioned according to the required strength and safety requirements.

Ved, som omhandlet i krav 3, at anvende glaselementer i det nævnte antal og den nævnte tykkelse, opnås ifølge den foretrukne udførelsesform en glasrudeenhed, der opfylder strenge krav til både styrke og sikkerhed.By using glass elements in the said number and thickness, as claimed in claim 3, according to the preferred embodiment, a glass pane unit which meets stringent requirements for both strength and safety is obtained.

Ved, som omhandlet i krav 4 og 5, at indsætte glasrudeenheden i en skibsflade, opnås en praktisk anvendelse af glasrudeenheden, hvor der kan drages særlig fordel af glasrudeenhedens soliditet overfor såvel vibrationer, stød og varmeudvikling.By inserting the glass pane unit into a ship's surface as claimed in claims 4 and 5, a practical application of the glass pane unit is achieved, where the glass pane unit's solidity to vibration, shock and heat generation can be particularly advantageous.

Ved, som omhandlet i krav 6, at anvende hul elforzinkede stålprofiler, der indeholder fugtabsorptionsmidler, opnås at restfugtigheden i den tilbageværende luft mellem glassene optages og dermed at luftens varmeledningsevne nedsættes.By using hollow electric galvanized steel profiles containing moisture absorbers, as claimed in claim 6, it is achieved that the residual moisture in the remaining air between the glasses is obtained and thus the air conductivity is reduced.

Endelig er det hensigtsmæssigt, som omhandlet i krav 7, at forsyne stålprofilens sider med fibervæv, for at opnå en vibrationsabsorberende lejring af glasset.Finally, as claimed in claim 7, it is appropriate to provide fiber sides of the steel profile to obtain a vibration-absorbing bearing of the glass.
