Den foreliggende opfindelse angår et sammensat profil samt en fremgangsmåde for fremstilling af et sådant sammensat profil, hvor det sammensatte profil omfatter to metal profil er, som holdes i afstand fra hinanden og er forbundet ved hjælp af i det mindste to 5 isolerende stænger, som er støbt jji si tu og derved fastgjort i riller mellem flanger på metal profil erne, idet det sammensatte profil er fremstillet med udgangspunkt i et metal profil, hvor de indre flanger er parvis forbundne over bropartier, som sammen med de indre flanger danner formbunde ved støbning af de isolerende 10 stænger.The present invention relates to a composite profile as well as to a method for producing such a composite profile, wherein the composite profile comprises two metal profiles which are spaced apart and connected by at least two insulating bars which are molded jji si tu and thereby fixed in grooves between flanges on the metal profiles, the composite profile being made from a metal profile where the inner flanges are connected in pairs over bridge portions which together with the inner flanges form moldings by casting the insulating 10 rods.

Fra beskrivelsen til norsk patentansøgning nr. 79.4124 kendes der et sådant sammensat profil samt en fremgangsmåde til dets fremstilling. Fremgangsmåden til fremstillingen består i, at der startes med et 15 udgangs-metalprofil, hvor to indre flanger, som afgrænser hver sin rille, hænger sammen over et broparti, således at dette danner formbund for støbningen af den ene isolerende stang fra oversiden.From the description of Norwegian patent application No. 79.4124, such a composite profile and a method for its preparation are known. The method of manufacture consists of starting with a starting metal profile, where two inner flanges defining each groove are interconnected over a bridge portion so as to form the molding of the one insulating rod from the upper side.

Derefter vendes udgangsprofilet, og den anden isolerende stang støbes fra oversiden. Til slut fjernes bropartierne, som forbinder 20 de indre flanger, f.eks. ved høvling, fræsning eller rivning, således at kun de isolerende stænger forbinder de to metal profil er, der er dannet.Then the output profile is reversed and the second insulating rod is cast from the top. Finally, the bridge portions connecting the inner flanges, e.g. by planing, milling or tearing so that only the insulating rods connect the two metal profiles are formed.

Ved det kendte profil afgrænser metal profil ernes vægge og de 25 isolerende stænger et hulrum. Varmeoverførslen gennem det sammensatte profil i retning langs de isolerende stænger, set i tværsnit af profilet, sker i form af ledning i de isolerende stænger, konvektion i luften i hulrummet og stråling mellem de indre / metal flader.In the known profile, the walls of the metal profiles and the 25 insulating bars define a cavity. The heat transfer through the composite profile in the direction along the insulating rods, seen in cross-section of the profile, takes the form of conduction in the insulating rods, convection in the air in the cavity and radiation between the inner / metal surfaces.

Det er formålet med den foreliggende opfindelse at tilvejebringe én forbedring af det kendte sammensatte profil med hensyn til isoleringsegenskaberne samt at tilvejebringe en fremgangsmåde til fremstilling af et sådant profil, hvilken fremgangsmåde indebærer en 35 forenkling med hensyn til selve fremstillingen.It is the object of the present invention to provide one improvement of the prior art composite profile with respect to the insulation properties and to provide a method for producing such a profile which involves a simplification of the fabrication itself.

Det sammensatte profil ifølge opfindelsen er kendetegnet ved, at bropartierne er splittet i profilets længderetning efter støbningen og er bukket bort fra de isolerende stænger.The composite profile according to the invention is characterized in that the bridge portions are split longitudinally of the profile after the casting and are bent away from the insulating rods.

Fremgangsmåden ifølge opfindelsen er kendetegnet ved, at bropartierne splittes i profilets længderetning efter støbningen og bøjes bort fra de isolerende stænger. Med den foreliggende 5 opfindelse kan der opnås en forbedring af varmeoverføringsmodstanden, både når det gælder konvektion og stråling. Navnlig kan varmeoverføring ved konvektion formindskes ved, at bropartierne skilles fra den ene flange eller splittes langs midten og bøjes' ind i hulrummet. De indadbøjede bropartier 10 virker hindrendé på luftcirkulationen og derved konvektionen. Ved passende forhold mellem tværsnitsdimensionerne for hulrummet kan det opnås, at de indadbukkede bropartier danner ribber, der virker som "bremse"-flader for luften, således at luftstrømmen i hulrummet bremses. Imidlertid bør der være i det mindste en spalte mellem de 15 indadbukkede brohalvdele, henholdsvis mellem de indadbukkede, hele broer og"flangerne på den modsatte side.The method according to the invention is characterized in that the bridge portions are split in the longitudinal direction of the profile after the casting and are bent away from the insulating rods. With the present invention, an improvement in heat transfer resistance can be achieved, both in convection and radiation. In particular, heat transfer by convection can be reduced by separating the bridge portions from one flange or splitting along the center and bending into the cavity. The inwardly bent bridge portions 10 act as an obstacle to the air circulation and thereby convection. By appropriate proportions of the cross-sectional dimensions of the cavity, it can be achieved that the inwardly bent bridge portions form ribs that act as "brake" surfaces for the air, so as to slow down the airflow in the cavity. However, there should be at least one gap between the 15 inwardly bent bridge halves, respectively, between the inwardly bent, full bridges and the "flanges on the opposite side.

Såfremt metal profil et er eloxeret før indstøbningen af de isolerende stænger, kan det af hensyn til varmeoverførslen ved stråling være 20 gunstigt, at bropartierne kun bukkes lidt ind i hulrummet, da de eloxerede flader af bropartierne vil virke som strålingsflader. Ved at bropartierne kun rager lidt ind i hulrummet, vil de alligevel formindske varmeoverførslen ved konvektion ved at bremse luftens bevægelser, samtidig med at det undgås, at bropartierne bidrager 25 væsentligt til varmeoverførslen ved stråling.If the metal profile is anodized prior to embedding the insulating rods, it may be beneficial for the heat transfer by radiation that the bridge portions be only slightly bent into the cavity, as the anodized surfaces of the bridge portions will act as radiation surfaces. However, by bridging the portions only slightly into the cavity, they will reduce the heat transfer by convection by slowing the movement of air, while avoiding that the bridge portions contribute significantly to the heat transfer by radiation.

Opfindelsen skal i det følgende beskrives nærmere under henvisning til tegningen, der viser et sammensat profil, hvor bropartierne er splittet langs midten, og halvdelene af begge bropartierne er bukket 30 ind i hulrummet i det sammensatte profil.The invention will now be described in more detail with reference to the drawing which shows a composite profile, with the bridge portions being split along the middle and the halves of both bridge portions being bent into the cavity of the composite profile.

Det viste sammensatte profil omfatter to metalprofil er 1 og 2, der naturligvis kan omfatte yderligere, ikke viste partier, som f.eks. kanaler til anbringelse af glas, eller tætningslister, eller partier 35 udformet til andre formål alt efter anvendelsen af det sammensatte profil.The composite profile shown comprises two metal profiles 1 and 2, which may of course comprise additional parts not shown, such as e.g. channels for placing glass, or sealing strips, or portions 35 designed for other purposes depending on the use of the composite profile.

Profilet omfatter isolerende stænger 3, der er indstøbt ved anvendelse af bropartierne 4 som en del af formbunden, idetThe profile comprises insulating rods 3 which are embedded using the bridge portions 4 as part of the mold base,

3 parvis. I det færdige profil er bropartierne bukket indefter i hulrummet og medfører en betydelig reduktion af varmeoverførslen ved konvektion. Den metalliske forbindelse mellem profilerne 1 og 2 er helt brudt» således at varmeledning alene sker gennem de isolerende 5 stænger 3. Disse har meget lille varmel edn ingsevne sammenlignet med metal.3 in pairs. In the finished profile, the bridge portions are bent inwardly into the cavity and result in a significant reduction of the heat transfer by convection. The metallic connection between profiles 1 and 2 is completely broken so that heat conduction occurs only through the insulating 5 rods 3. These have very little thermal conductivity compared to metal.

De isolerende stænger 3 er fastgjort mellem flanger 5 og 6 på hvert af profilerne 1 og 2.The insulating bars 3 are secured between flanges 5 and 6 on each of the profiles 1 and 2.

Med et udgangs-metal profil i form af et metal profil, der omfatter to parallelle bropartier, er det sammensatte profil fremstillet ved, at de isolerende stænger 3 støbes inu situ. hvorefer bropartierne 4 splittes i længderetningen og bukkes ind i hulrummet. Splitningen og 15 bukningen kan udføres i én operation ved brug af et værktøj, der føres gennem hulrummet og både splitter og bukker bropartierne, fortrinsvis samtidigt, således at metalprofilet kun udsættes for den frie kraft i længderetningen, idet sidekræfter på grund af splitningen og bukningen udligner hinanden.With an output metal profile in the form of a metal profile comprising two parallel bridge portions, the composite profile is made by molding the insulating rods 3 in situ. whereby the bridge portions 4 are split longitudinally and bent into the cavity. The splitting and bending can be performed in one operation by using a tool passing through the cavity and both splitting and bending the bridge portions, preferably simultaneously, so that the metal profile is exposed only to the longitudinal free force, side forces due to the splitting and bending equalize each other.

Bropartierne 4 kan splittes hovedsageligt midt mellem de indre flanger 6, hvorefter halvdelen af bropartierne 4. foldes indefter *v omkring de linier, hvor de hænger sammen med de indre flanger.The bridge portions 4 can be split mainly midway between the inner flanges 6, after which half of the bridge portions 4 are folded inwards around the lines where they are connected to the inner flanges.

25 Alternativt kan bropartierne 4 skilles fra en af de flanger 6, som hvert broparti hænger sammen med, for derefter at blive foldet ind i profilets hulrum. Adskillelsen kan udføres på en sådan måde, at de to bropartier 4 skilles fra en af flangerne 6 ved indbyrdes modsatte sider af profilet og derefter foldes ind in profilets hulrum.Alternatively, the bridge portions 4 may be separated from one of the flanges 6 with which each bridge portion is associated, and then folded into the cavity of the profile. The separation can be carried out in such a way that the two bridge portions 4 are separated from one of the flanges 6 at opposite sides of the profile and then folded into the cavity of the profile.
