Description
i 147801 ii 147801 i
Opfindelsen angår en fremgangsmåde til fremstilling 5 af en hermetisk forseglet samling mellem hule ram-meprofilelementer og i det mindste to glasplader og som angivet i kravets indledning.The invention relates to a method for the preparation of a hermetically sealed joint between hollow frame profile elements and at least two glass sheets and as stated in the preamble of the claim.
En almindelig fremgangsmåde til fremstilling af en 10 fugttæt samling af rammeprofilelementer til isolationsruder omfatter to trin: 1. Samling af rammeprofilelementerne ved isættel-se af hjørneelementer i profilelementernes hu- 15 le ender.A common method of producing a moisture-proof assembly of frame profile elements for insulation panes comprises two steps: 1. Assembly of the frame profile elements by inserting corner elements into the hollow ends of the profile elements.
2. Tilvejebringelse af en fugttæt samling mellem de samlede profilelementer ved enten at hælde en hærdende tætningsmasse ind i samlings- 20 hulrummene eller ved svejsning af enderne af de samlede profilelementer.2. Providing a moisture-tight joint between the assembled profile elements by either pouring a curing sealant into the joint cavities or by welding the ends of the assembled profile members.
De almindeligt kendte hjørneelementer til samling af rammeprofilelementer tilvejebringer kun den bærende 25 konstruktion uden at sikre en fugttæt forsegling, hvilket f.eks. er kendt fra dansk patentansøgning nr. 6375/74 og beskrivelserne til de tyske patenter nr. 2.260.691 og nr. 1.509.155· En kendt løsning på dette tætningsproblem er beskrevet i britisk patent 30 nr. 1.206.751, ifølge hvilken en kontinuert tætningsliste bliver lagt langs periferien, anbragt på den mod rudemellemrummet vendende side af rammeprofilelemen-terne og hjørnerne, hvorved hjørneelementerne ikke behøver at danne en vandtæt forsegling. Denne frem- 147801 2 1 gangsmåde er imidlertid kostbar, da den kræver en stor mængde tætningsmateriale og også lider af ulempen ved det betydeligt reducerede synsfelt ved anvendelsen af tætningslister.The commonly known corner elements for assembling frame profile elements provide only the supporting structure without securing a moisture-tight seal, e.g. is known from Danish Patent Application No. 6375/74 and the descriptions of German patents Nos. 2,260,691 and 1,509,155 · A known solution to this sealing problem is disclosed in British Patent No. 30,206,751, according to which a continuous sealing strips are laid along the periphery, arranged on the side facing the pane space of the frame profile elements and corners, whereby the corner elements do not have to form a watertight seal. However, this approach is costly as it requires a large amount of sealing material and also suffers from the disadvantage of the significantly reduced field of view when using sealing strips.

Pra tysk offentliggørelsesskrift nr. 2.347.824 kendes en fremgangsmåde af den i kravets indledning angivne art, men hvor man anvender hjørneelementer belagt med et termoplastisk materiale, som ved sædvanlige tempe-10 raturer er fast og hårdt, hvorfor ruden opvarmes under samlingen. Det er udover materialet på hjørneelementerne, nødvendigt at tilføre et yderligere tætningsmiddel for at sikre hermetisk tætte samlinger i hele rudens levetid, idet det termoplastiske materiale 15 primært skal sammenholde profilelementerne.German Patent Publication No. 2,347,824 discloses a method of the kind specified in the preamble of the claim, but where corner elements are coated with a thermoplastic material which is solid and hard at normal temperatures, and therefore the pane is heated during assembly. In addition to the material on the corner elements, it is necessary to add an additional sealant to ensure hermetically sealed joints throughout the life of the pane, since the thermoplastic material 15 must primarily match the profile elements.
Formålet med opfindelsen er at angive en fremgangsmåde til fremstilling af isoleringsruder af den i kravets indledning angivne art, hvorved man altid 20 er sikker på, at der er en tilstrækkelig mængde tætningsmateriale til sikring af hermetiske samlinger, samt at tætningsmaterialet forbliver smidigt og stærkt klæbende i hele rudens levetid.The object of the invention is to provide a method of manufacturing insulating panes of the kind set forth in the preamble of the claim, thereby always ensuring that there is a sufficient amount of sealing material for securing hermetic joints and that the sealing material remains flexible and strongly adhesive. the entire life of the pane.
25 Dette opnås ved at gå frem som angivet i kravets kendetegnende del. Fremgangsmåden er således ejendommelig ved tre trin, nemlig: 1. anvendelse af et vinkelstykke påført en tæt-30 ningsmasse af en bestemt type og i en sådan mængde, at hjørneelementets tværsnitsareal er større end profilelementernes indre hulrums tværsnitsareal, 3 147801 1 2. isættelse af hjørneelementerne i profilelemen terne, således, at tætningsmassen delvist presses ud under isætteisen, og 5 3· opvarmning af både profilelementerne og hjørne elementerne, således at varmeudvidelsen af profilelementerne giver en sikker tætning i de gerede hjørner, idet materialeudvidelsen ved opvarmning giver en sammenpresning i hjørner-10 ne.This is achieved by proceeding as set out in the characterizing part of the claim. The method is thus characterized by three steps, namely: 1. using an angle piece applied to a sealant of a certain type and in such an amount that the cross-sectional area of the corner element is larger than the cross-sectional area of the profile elements; the corner elements of the profile elements so that the sealant is partially squeezed out under the insertion, and 5 3 · heating of both the profile elements and the corner elements, so that the thermal expansion of the profile elements provides a secure seal in the finished corners, as the material expansion upon heating gives a compression in corners. -10 no.
Hermed kan man visuelt sikre sig, at der er tilstrækkeligt tætningsmateriale, idet noget af materialet trykkes ud allerede ved den indledende samling jævn-15 før punkt 1. og 2. Også den endelige samling kan kontrolleres visuelt, idet den af opvarmningen yderligere forårsagede sammenpresning af hjørnerne giver en yderligere udpresning af tætningsmateriale, samtidig med at endefladerne af de gerede hjørner presses 20 stærkt sammen omkring det mellemliggende tætningsmateriale.Hereby it can be visually ensured that there is sufficient sealing material, since some of the material is already printed at the initial assembly evenly before points 1 and 2. Also, the final assembly can be visually checked, since the heating caused further compression of the the corners provide a further squeeze of sealing material, while at the same time the end surfaces of the made corners are strongly compressed around the intermediate sealing material.
De fremstillede isoleringsruder fremstillet ved fremgangsmåden ifølge opfindelsen kan, alt efter hvortil 25 de skal anvendes, efterbearbejdes. Til visse anvendelser kan den rude, der er fremstillet efter fremgangsmåden ifølge kravet anvendes direkte.The insulated glazing produced by the method according to the invention can be reworked, depending on which they are to be used. For certain applications, the pane manufactured according to the method of the claim may be used directly.
Til andre anvendelser må man afskære eller på anden 30 måde fjerne i hvert fald en del af den udpressede tætningsmasse. Til andre anvendelser kan ruden forsynes med en sekundær tætning, således at man får en dobbelt-tætning, ved at påføre en siliconemasse hele vejen rundt langs randsamlingerne, således at 147801 4 1 silicone-massen også 'dækker den udpressede tætnings masse, der eventuelt kan være delvis afskåret inden påføringen af silicone-massen.For other applications, one must cut or otherwise remove at least part of the extruded sealant. For other applications, the pane may be provided with a secondary seal so as to obtain a double seal by applying a silicone mass all the way around the rim joints so that the mass of the silicone also covers the mass of the extruded seal which may be partially cut off before applying the silicone mass.
5 Opfindelsen forklares nærmere under henvisning til tegningen, hvor fig. 1 viser et foretrukket hjørneelement set forfra, fra bunden og fra siden, 10 fig. 2 viser et profilelement og et hjørneelement før de er samlede, fig. 3 viser et samlet hjørneparti, og 15 fig. 4 viser et tværsnit af et hjørneparti.The invention is further explained with reference to the drawing, in which fig. 1 shows a preferred front, bottom and side corner element; FIG. 2 shows a profile element and a corner element before assembling; FIG. 3 shows an overall corner portion, and FIG. 4 shows a cross section of a corner portion.
Pig. 1 viser et hjørneelement 1, bestående af to indbyrdes vinkelrette arme af et relativt stift materia-20 le, f.eks. aluminium eller plast. Hjørneelementet 1 er dækket af et smidigt, smeltbart materiale 2. Materialet 2 består af en stærkt klæbende termoplastisk iso-butylenpolymerholdig masse, som klæber godt til aluminium og glas, når det opvarmes.Pig. 1 shows a corner element 1 consisting of two mutually perpendicular arms of a relatively rigid material, e.g. aluminum or plastic. The corner element 1 is covered by a flexible, meltable material 2. The material 2 consists of a highly adhesive thermoplastic iso-butylene polymer containing mass which adheres well to aluminum and glass when heated.

Fig. 2 viser profilelementer 3, som består af aluminium og har et hult profil med en langsgående not i den indre overflade. Hulrummet 8 i hvert profilelement fyldes normalt med et tørremiddel. Profilelementer-30 nes ender skæres til med en vinkel på 45° (geret) således, at de passer sammen i hjørnet. Ydermere er profilelementernes overflade, som vender mod glaspladerne, forsynet med strimler af et bindemiddel 4, som er dækket med siliconpapir.FIG. 2 shows profile elements 3, which are made of aluminum and have a hollow profile with a longitudinal groove in the inner surface. The cavity 8 in each profile element is usually filled with a desiccant. The ends of the profile elements 30 are cut at an angle of 45 ° (fence) to fit in the corner. In addition, the surface of the profile elements facing the glass sheets is provided with strips of a binder 4 covered with silicone paper.
5 147801 1 Pig. 3 viser det samlede hjørne. Ved indsættelsen af hjørnelementet 1 i profilelementet presses materialet 2 ud, således at det udfylder hjørnepartiets hulrum, som det fremgår af fig. 4. Ydermere presses oversky-5 dende materiale ud og danner en opsamling 6 på hjør net.5 147801 1 Pig. 3 shows the total corner. Upon insertion of the corner element 1 into the profile element, the material 2 is pressed out so as to fill the cavity of the corner portion, as shown in FIG. 4. In addition, excess material is extruded to form a collection 6 on the corner mesh.
Samlingen af isolationsruden sker på følgende måde. Profilelementerne skæres ud, således at de passer 10 inden i den foreliggende vinduesramme, som skal omdannes til en isolationsrude. Endvidere skæres en anden glasplade ud. Profilelementerne geres sammen i en vinkel på 45°.The insulation pane assembly is done as follows. The profile elements are cut out to fit 10 within the present window frame which is to be converted into an insulation pane. Furthermore, another glass plate is cut out. The profile elements are assembled at an angle of 45 °.
15 Derefter samles profilelementerne ved først at indsætte hjørneelementerne 1 i de lange elementer og derefter i de korte, idet profilelementernes hulrum først er blevet fyldt med et tørremiddel. Det beskyttende siliconpapir fjernes fra den ene side af rammen, og en 20 elektrisk modstandstråd 7 lægges ned i tætningslisten 4 (fig. 3). Modstandstråden pålægges fra en rulle ved hjælp af et specialværktøj med en nål og efterlades i den færdige rude. Profilelementerne placeres i den eksisterende vinduesramme, siliconpapiret fjernes fra 25 den anden side og modstandstråden nedlægges også på denne side af tætningslisten og skæres til sidst af med frie ender på 10 cm. De nye glasplader monteres, den elektriske modstandstråd forbindes til en vario-transformer, og en elektrisk strøm tilsluttes i ca.15 The profile elements are then assembled by first inserting the corner elements 1 into the long members and then into the short ones, the cavity of the profile members having first been filled with a desiccant. The protective silicone paper is removed from one side of the frame and an electric resistance wire 7 is placed in the sealing strip 4 (Fig. 3). The resistance wire is applied from a roll using a special tool with a needle and left in the finished pane. The profile elements are placed in the existing window frame, the silicone paper is removed from the other side and the resistance wire is also placed on this side of the sealing strip and eventually cut off with free ends of 10 cm. The new glass panels are mounted, the electrical resistance wire is connected to a vario transformer, and an electric current is connected for approx.
30 10 minutter for at opvarme tætningsmassen og profil elementerne. Derefter presses de to plader ind mod hinanden, og konstruktionen forstærkes ved hjælp af transparent silicone, da den anvendte tætningsmasse 147801 6 1 aldrig hærder og ikke kan bære vægten af glaspladen.30 10 minutes to heat the sealant and profile elements. Then, the two sheets are pressed against each other and the structure is reinforced by transparent silicone, since the sealant used never cures and cannot support the weight of the glass sheet.
Yderligere limer tætningsmassen først sikkert mod glas ved en temperatur på omkring 70° C, og hvis et passende tryk påføres mod glaspladen. Profilelementernes 5 varmeudvidelse sikrer, at de gerede ender trykkes tilstrækkeligt meget mod hinanden til, at tilvejebringe det nødvendige tryk til at tætningsmassen vil lime mod alle overflader ved hjørnepartiet. Hjørnepartierne vil således blive forseglet sikkert uden brug af 10 større mekanisk tryk, hvilket ellers ville være vanskeligt, da der ikke er plads til at påføre et mekanisk tryk ved hjørnepartiet.In addition, the sealant first adhesively adheres to glass at a temperature of about 70 ° C and if an appropriate pressure is applied to the glass plate. The thermal expansion of the profile elements 5 ensures that the projected ends are pressed sufficiently against each other to provide the necessary pressure for the sealant to adhere to all surfaces at the corner portion. Thus, the corner portions will be sealed securely without the use of 10 larger mechanical pressures, which would otherwise be difficult as there is no room to apply a mechanical pressure at the corner portion.
Hjørneelementet 1 med det smidige materiale 2 tilveje-15 bringer profilelementernes samling, hvorved det smidige ge materiale sørger for en indre forsegling ved hjørnepartierne, udfylder hulrummene mellem enderne af tilstødende profilelementer og danner en bro mellem tætningslisterne 4 ved hjørnepartierne, således at de 20 forløber ubrudt.The corner element 1 with the flexible material 2 provides the assembly of the profile elements, whereby the flexible material provides an internal seal at the corner portions, fills the voids between the ends of adjacent profile elements and forms a bridge between the sealing strips 4 at the corner portions, so that the 20 bridges extend. .
Efter opvarmningen er der opnået en hermetisk forsegling mellem glasset og de to profilelementer 5 og profilelementernes 6 gerede ender.After the heating, a hermetic seal is obtained between the glass and the two profile elements 5 and the ends of the profile elements 6.

Det anvendte klæbende og smidige materiale består af et materiale indeholdende en isobutylenpolymer. Et passende materiale kan have følgende sammensætning: 30 Klorineret isobutylen- isopren-copolymer 100 vægtdele FEF-black 30 - U7801 7 1 Kalcium-karbonat fyIdemasse 50 vægtdeleThe adhesive and flexible material used consists of a material containing an isobutylene polymer. A suitable material may have the following composition: 30 Chlorinated isobutylene isoprene copolymer 100 parts by weight FEF-black 30 - U7801 7 1 Calcium carbonate feed mass 50 parts by weight

Forsøg har vist en fremragende udførelse af den foretrukne fugttætte samling. Hjørneelementet udfylder 20 alle hulrum under trykket fra indsættelsen, og dets sammenklæbning til aluminiumsprofilerne sker som følge af opvarmningen fra den elektriske modstandstråd. Det nødvendige tryk til at bevirke sammenklæbning af det smeltede hjørnemateriale til profilelementerne skabes 25 ved hjælp af varmeudvidelsen af profilelementerne under påtrykningen af den elektriske strøm. Dette termiske tryk er vigtigt, da der ikke er plads i rammen til at påføre et mekanisk tryk.Tests have shown an excellent performance of the preferred moisture-proof assembly. The corner element fills all of the cavities under the pressure from the insert, and its adhesion to the aluminum profiles occurs as a result of the heating of the electrical resistance wire. The pressure required to effect adhesion of the molten corner material to the profile elements is created by the heat expansion of the profile elements during the application of the electric current. This thermal pressure is important as there is no space in the frame to apply a mechanical pressure.
