MenetelmS lasin kiinnittSmiseksi kehykseen lasitusraassallaA method of attaching glass to a frame with a glazing bead

Keksinto kohdistuu menetelmaån lasilevyn kiinnit-5 tSmiseksi kehykseen lasitusmassalla, jossa lasilevy asetetaan sen takapinta kohti kehyksessa olevaa olakepintaa siten, ettS lasilevyn reunan ja kehyksen valiin jaa rako, ja lasitusmassaa johdetaan lasilevyn etupuolelta eli asetussuunnan puolelta lasilevyn 10 kiinnittåmiseksi.The invention relates to a method for attaching a glass sheet to a frame with a glazing compound, wherein the glass sheet is placed on its rear surface towards the shoulder surface in the frame so that a gap is divided between the edge and the frame of the glass sheet.

Kiinnitettaessa lasilevyja puitteeseen kåytetaan yleisesti menetelmSS, jossa siihen pintaan puitteessa, jota vasten lasi tulee, levitetSSn massaa, minka 15 jalkeen lasi sijoitetaan puitteeseen. Tåmån jalkeen lasin etupinnalle levitetSan viela toinen kerros massaa ja lasi tuetaan ulkopuolelta viela irrallisella lasilistalla, jolloin lasitusmassa jaa lasin ja lasilistan valiin. Lasilistan sijasta voidaan lasin 20 tuentaan ulkopuolelta kSyttSS puitteeseen lyotavia nauloja, joiden pSSlle massakerros levitetSan.When attaching glass sheets to a frame, a method is generally used in which a mass is applied to the surface on which the glass comes, after which the glass is placed in the frame. After this, another layer of mass is applied to the front surface of the glass and the glass is supported on the outside with a still loose glass strip, whereby the glazing mass divides the glass and the glass strip. Instead of a glass strip, nails can be used to support the glass 20 from the outside into the frame, on the pSS of which a mass layer is applied.

EdellS mainittu menetelmS kSsittSS monta tyovaihetta, ja massa joudutaan esimerkiksi levittSmSSn kahdessa 25 vaiheessa, ensin lasilevyn takapuolelle, ja kun lasilevy on asetettu paikoilleen, vielS etupuolelle.The aforementioned method involves many working steps, and the pulp is applied, for example, in two steps of application, first to the back of the glass sheet and, when the glass sheet is in place, still to the front.

Ruotsalaisessa kuulutusjulkaisussa 344608 on esitetty menetelmS, jossa lasi asetetaan takapinta vasten 30 kehyksessa olevaa olakepintaa olakepinnalla olevan listan paSlle. Lasitusmassa levitetSSn kahdessa vaiheessa siten, ettS ensimmSisessS vaiheessa massa levitetSSn kaksiruutuisen lasin reunan ja kehyksen vSliin ja toisessa vaiheessa ruudun etupuolelle.Swedish Offenlegungsschrift 344608 discloses a method in which glass is placed against the back surface of a frame 30 on a shoulder surface on a list on the shoulder surface. The glazing mass is applied in two steps, so that in the first step the mass is applied between the edge and the frame of the double-glazed glass and in the second step to the front of the screen.

35 MenetelmS on tarkoitettu kasiruutuisten lasien ruutujen kiinnittSmiseksi toisiinsa samalla kun lasi kiin-nitetSSn kehykseen. Lasi jSS kuitenkin takapinnaltaan kiinnittSmattS tSssS menetelmSssS.35 The method is for attaching the panes of hand-pane glass to each other while the glass is attached to the frame. However, glass in this method is not fixed at the back.

Keksinnon tarkoituksena on poistaa edellåmainitut epåkohdat ja esittåå menetelma, jossa lasitusmassa voidaan levittåå yhdessa vaiheessa, mutta jol la 5 kuitenkin saadaan hyva kiinnitys. Tåmån tarkoituksen toteuttamiseksi keksinnon mukaiselle menetelmSlle on paaasiassa tunnusomaista se, etta lasitusmassa levi-tetåån yhdessa vaiheessa siten, ettå se leviaa lasi-levyn reunan ja kehyksen valisen raon kautta olakepin-10 nan ja lasilevyn takapinnan valiseen tilaan, josta sen leviaminen edelleen estetåan roainitun tilan lasilevyn keskiosan suuntaan sulkevalla pidSttimella, ja sita jaa lasilevyn asetussuunnan puolelle yhteyteen lasilevyn etupinnan ja kehyksen sisapinnan kanssa. 15 T311S tavoin voidaan lasilevyn kiinnitys kehykseen seka etu- etta takapuolelta suorittaa saman, yhdessa vaiheessa levitettavån massan avulla sen jalkeen, kun lasilevy on kohdistettu oikein sitS ymparoiviin kehysosiin nahden.The object of the invention is to eliminate the aforementioned drawbacks and to present a method in which the glazing mass can be applied in one step, but with which a good adhesion is nevertheless obtained. To achieve this object, the method according to the invention is mainly characterized in that the glazing mass is applied in one step so that it spreads through the gap between the edge of the glass sheet and the frame into the space between the shoulder pin with a holder closing in the direction of the central part, and divides it on the setting direction side of the glass plate in contact with the front surface of the glass plate and the inner surface of the frame. Like the T311S, the attachment of the glass sheet to the frame from both the front and the rear can be performed by means of the same mass applied in one step after the glass sheet has been correctly aligned with respect to the frame parts surrounding the sitS.

Kuvassa 1 on esitetty keksinnon mukaisessa menetelmassa kaytettavS kehys 1. Kehys on ikkunan kSSntyvS puite, mutta keksintoa voidaan luonnollisesti kayttaa myos 5 lasilevyjen kiinnittåmiseksi kaantymattomiin karmeihin. Puitteessa on siina reunassa, johon lasilevy tulee, erityinen kehyksestå sen rajaamaan sisaosaan pain ulkoneva lasituskynte 2. Lasituskyntteessa on olake-pinta 2a, joka rajoittuu kehyksen puolella siihen 10 nahden poikittaiseen puitteen sisapintaan 3. Olakepinta 2a on suunnilleen kehyksen 1 rajaaman kehystason (se taso, jossa lasilevy sijaitsee) suuntainen ja tatå tasoa on kuvattu pistekatkoviivalla A. Olakepinta 2a paattyy kehyksen rajaaman sisaosan puoleisella reunalla 15 samaan suuntaan sisapinnan 3 kanssa suuntautuvaan ulkonemaan 2b, jossa on kehystason A suuntainen tukipinta 2c.Figure 1 shows a frame 1 used in the method according to the invention. The frame is a window-friendly frame, but the invention can of course also be used for attaching glass sheets to non-curved frames. The frame has a special glazing nail 2 protruding from the frame into the inner part delimited by the frame at the edge to which the glass sheet enters. The glazing nail has a shoulder surface 2a bounding on the frame side where the glass sheet is located) and this plane is depicted by the dotted line A. The shoulder surface 2a abuts on the inner side 15 delimited by the frame in the same direction as the inner surface 3.

Kuvassa 2 on havainnollistettu lasilevyn kiinnitysta 20 keksinnon mukaisella menetelmallS. Lasilevy 4 asetetaan tukipintaa 2c vasten nuolella B merkitystS asennussuun-nasta eli sivun 3 suunnasta siten, etta sen reuna peittaa osittain olakepinnan 2a, ja lasilevyn ulkoreu-nan ja kehyksen sisSpinnan 3 valiin jSS tailoin tietty 25 asennusvara eli rako. Tasså raossa voi olla sinansa tunnettuja lyhyita kiilapaloja kehyksen 1 ja lasilevyn 4 sijoittamiseksi oikein toisiinsa nahden. NMmå palat ovat sinånså tunnettuja eika niita ole tåssa kuvattu sen tarkemmin. Kun lasilevy on kohdistettu oikein 30 kehykseen 1, pursotetaan lasilevyn 4 etupuolelta eli asetussuunnan B puolelta sopivalla tydkalulla tiivis-tysmassaa 5, joka leviåa asennusvarana toimivan raon kautta myds olakepinnan 2a ja lasilevyn 4 takapinnan valiseen tilaan kosketuksiin sekS olakepinnan ettS 35 lasilevyn takapinnan kanssa, samalla kun osa massasta jaå kerrokseksi lasilevyn etupinnan ja kehyksen sisapinnan 3 valille. Nain voidaan samalla, yhdesså vaiheessa levitettSvålla lasitusmassakerroksella 4 kiinnittaa lasi kehykseen 1 seka etu- etta takapinnal-ta. Olakepintaa 2a lasilevyn keskiosaan pain rajoittava ulkonema 2b eståå yhdesså tukipintaa 2a vasten olevan lasilevyn kanssa massan pursuamisen pois kehyksen 5 keskelle pain.Figure 2 illustrates the attachment of a glass sheet 20 by the method according to the invention. The glass sheet 4 is placed against the support surface 2c in the installation direction indicated by the arrow B, i.e. from the direction of the side 3, so that its edge partially covers the shoulder surface 2a and the outer edge of the glass sheet and the frame inner surface 3. This slit can have short wedge pieces known per se for placing the frame 1 and the glass plate 4 correctly relative to each other. The pieces are known per se and are not described in more detail here. When the glass sheet is correctly aligned with the frame 1, a sealing compound 5 is extruded from the front side of the glass sheet 4, i.e. from the setting direction B, through a gap acting as a mounting space into the space between the shoulder surface 2a and the rear surface of the glass sheet 4. part of the mass is divided into a layer between the front surface of the glass plate and the inner surface 3 of the frame. Thus, with the same layer of glazing compound 4 applied in one step, the glass can be attached to the frame 1 as well as from the front back surface. The protrusion 2b, which limits the shoulder surface 2a to the center of the glass plate, together with the glass plate against the support surface 2a, prevents the mass from bursting out in the middle of the frame 5.

Menetelmåsså kaytetaan sellaista tyokalua, jossa on massaa ulos johtavan suuttimen kummallakin puolella pinnat, jotka tiivistyvåt seka lasilevyn 4 etupintaa 10 ettS kehyksen sisåpintaa 3 vasten massaa levitettaessa. Tåta tyokalua on kuvattu kuvassa 2 katkoviivalla 6. Nain varmistetaan se, ettå massa leviSa riittavalla paineella niin, etta se tunkeutuu myos raon kautta lasilevyn takapinnalle.The method uses a tool with surfaces on each side of the nozzle leading out the mass, which seal and the front surface 10 of the glass sheet 4 against the inner surface 3 of the frame when the mass is applied. This tool is illustrated by a dashed line 6 in Figure 2. This ensures that the LeviSa is pressurized with sufficient pressure so that it also penetrates through the gap onto the back surface of the glass plate.

Kuvien 1 ja 2 kehyksessa 1 on ulkonema 2b samaa kappaletta kehyksen 1 kanssa, eli se muodostetaan osaksi kehyksen muodostamaa profiilia samasta kappa-leesta valmistusvaiheessa. Kuvassa 3 on havainnollis-20 tettu vaihtoehtoa, jossa massan levitys tapahtuu muuten samalla periaatteella, mutta ulkonema 2b muodostuu erillisesta pitkanomaisesta kappaleesta, jossa olevaa tukipintaa 2c vasten lasilevy 4 asetetaan. Kappale voidaan kiinnittaa muuhun kehykseen 1 jollain 25 sopivalla menetelmålla. Kappale voi olla samaa materiaalia kuin muu kehys, mutta se voi olla myos elastinen tiivistelista, joka tiivistyy tukipinnaltaan 2c lasilevya vasten.The frame 1 of Figures 1 and 2 has a protrusion 2b integral with the frame 1, i.e. it is formed as part of the profile formed by the frame from the same piece in the manufacturing step. Figure 3 illustrates an alternative in which the application of the mass otherwise takes place on the same principle, but the protrusion 2b consists of a separate elongate body in which a glass plate 4 is placed against the support surface 2c. The body can be attached to the rest of the frame 1 by any suitable method. The piece may be of the same material as the rest of the frame, but it may also be an elastic sealing strip which seals against its support surface 2c against a glass plate.

30 Kuvassa 4 on esitetty viela sellainen menetelma, jossa lasilevyn 4 takapinnan ja olakepinnan 2a valista tilaa ei ole suljettu lasilevyn keskiosan puolelta kehyksesså olevalla osalla, vaan olakepinta jatkuu suorana kehyksen sisåreunaan asti. Lasilevy on tålloin 35 asetettu tietylle etaisyydelle olakepinnasta 2a lasilevyn ja olakepinnan valiin asetettavilla lyhyillå paloilla, jotka voivat olla samantyyppisia kuin lasilevyn ulkoreunan ja kehyksen sisapinnan 3 valiin 5 91311 asetettavat kiilapalat. Lasilevy voidaan asemoida myos muilla tavoilla kehykseen. Lasitusmassa 5 levite-taan kuten edellS tyokalussa 6 olevasta suuttimesta, jolloin se leviSa olakepinnan 2a ja lasilevyn takapin-5 nan våliseen tilaan, ja sen leviåminen edelleen kehyksen keskelle pain estetaSn kehyksen sisareunan kohdalla olevan irrallisen kappaleen 2b avulla, joka sulkee lasilevyn 4 takapinnan ja olakepinnan 2a vSlisen, kehyksen keskelle påin avoimen raon ja joka 10 massan asetuttua otetaan pois. Kappale voi tålloin olla esim. koko kehyksen sivun pituudelle sijoitettu pitkånomainen lista, joka otetaan pois kun massa on levitetty tahan kehyssivuun. Kappale voidaan jarjestaa myos liikkuvaksi samaan suuntaan massaa levittavan 15 tyokalun 6 kanssa, jolloin sijainti tyokaluun 6 nahden kehyksen 1 pituussuunnassa voidaan jarjestaa sopivaksi. Kappale 2b voi tålloin olla liitetty mekaanisesti tyokaluun 6 tai sen liike voidaan synkronoida muulla tavoin tyokalun 6 liikkeen kanssa. Kappale muotoillaan 20 siten, etta se tiivistaa myos kehyksen kulmakohdat tyokalun 6 kulkiessa kulmakohdan ympåri.Fig. 4 still shows a method in which the space between the rear surface of the glass sheet 4 and the shoulder surface 2a is not closed from the middle part of the glass sheet by a part in the frame, but the shoulder surface continues straight to the inner edge of the frame. The glass sheet is then placed 35 at a certain distance from the shoulder surface 2a with short pieces to be set between the glass sheet and the shoulder surface, which may be of the same type as the wedge pieces to be set between the outer edge of the glass sheet and the inner surface 3 of the frame. The glass plate can also be positioned in the frame in other ways. The glazing mass 5 is applied as before from the nozzle in the tool 6, whereby it spreads between the shoulder surface 2a and the rear surface 5 of the glass plate, and its further spread to the center of the frame is prevented by a loose body 2b at the inner edge of the frame. 2a vSll, open in the middle of the frame and every 10 masses are removed. The piece can then be, for example, an elongated strip placed along the entire length of the side of the frame, which is removed when the mass is applied to any side of the frame. The body can also be arranged to move in the same direction as the pulp spreading tool 6, whereby the position in the longitudinal direction of the frame 1 relative to the tool 6 can be arranged to fit. The body 2b can then be mechanically connected to the tool 6 or its movement can be synchronized in another way with the movement of the tool 6. The body is shaped 20 so that it also seals the corner points of the frame as the tool 6 passes around the corner point.

Massana voidaan kayttaa mitM tahansa tunnettua levitys-ominaisuuksiltaan sopivaa levitettaessS notkeaa, 25 mutta kovetuttuaan lujasti 1 iimaavaa massaa, esimerkik- si sellaisia silikonipohjaisia massoja tai polyuretaa-nimassoja, jotka kovettuessaan såilyttåvat tietyn elastisuuden, jotta lasin ja kehyksen erilaiset lampolaajenemiset eivat olisi haitaksi. Tallaiset 30 elastiset liimaavat massat muodostavat myos hyvån kosteuden ja aanen eristyksen sijaitessaan lasin ja kehyksen valissa. T&llaisen kiinnityksen hyvia ominai-suuksia voidaan vielS tehostaa kåytettaesså elastista tiivistyslistaa ulkonemana 2b.Any known flexible pulp with suitable application properties can be used as the pulp, but after hardening 1 the adhesive pulp, for example silicone-based pulps or polyurethane pulps, which retain a certain elasticity when cured so that the glass and frame have different adhesions. Such elastic adhesive masses also provide good moisture and sound insulation when located between the glass and the frame. The good properties of such an attachment can be further enhanced by using an elastic sealing strip as a protrusion 2b.

Keksinto soveltuu kaytettavSksi kaikenlaatuisten kehysmateriaalien, kuten puu- tai alumiinikehysten yhteydessa, ja kehyksella tarkoitetaan tassa yhteydessa 35 6 sekS kSåntyvia puitteita etta kiinteitS karmeja. LisSksi terrains "lasilevy" tarkoitetaan kaikkia ISpinSkyvSsta tai lapinSkymattomasta materiaalista valmistettuja levymaisia materiaaleja, jotka kiin-5 nitetaSn kehykseen ja jotka eivat valttSmStta ole materiaaliltaan lasia.The invention is suitable for use in connection with all kinds of frame materials, such as wooden or aluminum frames, and in this context means a frame and fixed frames. In addition, terrains "glass plate" means any plate-like material made of a transparent or non-flammable material which is fixed to the frame and which is not of glass material.

Keksinnon mukaisella menetelmSllS voidaan lasilevyjen kiinnitys suorittaa myos automaattisesti, jolloin 10 lasilevyn paikalleen asetuksen jalkeen massaa levittSva tyokalu 6 kiertaa koko kehyksen ympari pursottaen tiivistysmassan 5 paikoilleen.With the method according to the invention, the fixing of the glass sheets can also be performed automatically, whereby after the glass sheet 10 has been placed in place, the tool 6 applying the mass rotates around the entire frame, extruding the sealing compound 5 into place.
