Description

Die Erfindung betrifft eine Kunstglas-Isolierscheibe aus mindestens zwei Scheiben aus Kunststoff und dazwischen angeordneten, im wesentlichen rohrförmigen, aneinanderstossenden Stegrahmen aus Kunststoff, deren Stirnränder mit den Scheiben verschweisst sind.The invention relates to a synthetic glass insulating pane made of at least two panes made of plastic and arranged between them, essentially tubular, abutting web frames made of plastic, the end edges of which are welded to the panes.

Bekannt sind Kunstglas-Isolierscheiben mit in einer Richtung (Extrusionsrichtung) verlaufenden Stegen. Eine derartige Kunstglas-Isolierscheibe hat unterschiedliche Widerstandsmomente in Längsrichtung und in Querrichtung der Stege. Diese Kunstglas-Isolierscheibe erfordert eine vergleichsweise grosse Wandstärke. Ausserdem ist die Wärmedurchgangszahl vergleichsweise gross, weil kaminartige Luftkammern vorhanden sind.Plastic insulating glass panes with webs running in one direction (extrusion direction) are known. Such an insulating glass pane has different moments of resistance in the longitudinal direction and in the transverse direction of the webs. This synthetic glass insulating pane requires a comparatively large wall thickness. In addition, the heat transfer coefficient is comparatively large, because chimney-like air chambers are available.

Eine Kunstglas-Isolierscheibe der eingangs genannten Art ist in der DE-A Nr. 1921624 beschrieben. Dort sind die Stegrahmen unmittelbar beim Vergiessen der Scheiben mit denselben verschweisst. Daher können sich die Stegrahmen unterschiedlich in die Scheiben eindrücken, so dass sich Verkantungen ausbilden. Infolgedessen ist keine gleichmässige gegenseitige Abstützung der Stegrahmen gewährleistet.A synthetic glass insulating washer of the type mentioned is described in DE-A No. 1921624. There the web frames are welded to them immediately when the panes are cast. Therefore, the web frames can press into the panes differently, so that canting is formed. As a result, no uniform mutual support of the web frames is guaranteed.

Aufgabe der Erfindung ist die Bereitstellung einer Kunstglas-Isolierscheibe, die bei geringer Wandstärke der einzelnen Scheiben eine stabile Verbindung zwischen Stegrahmen und Scheiben sicherstellt, wobei die Stegrahmen durch formschlüssige gegenseitige Anlage zur Stabilität beitragen sollen. Hierdurch soll ein gleichmässig hohes Widerstandsmoment in allen Richtungen und eine möglichst kleine Wärmedurchgangszahl erzielt werden.The object of the invention is to provide a synthetic glass insulating pane which ensures a stable connection between the web frame and the panes with a small wall thickness of the individual panes, the web frames being intended to contribute to stability by means of a form-fitting mutual contact. This is to achieve a uniformly high section modulus in all directions and the lowest possible heat transfer coefficient.

Diese Aufgabe wird nach der Erfindung durch die Kombination folgender Merkmale gelöst:

  • a) die Stirnränder der Stegrahmen besitzen nach aussen überstehende Randleisten;
  • b) senkrecht zu der durch die Stirnränder und Randleisten gebildeten Stirnfläche sind in Richtung auf die jeweils benachbarte Scheibe verlaufende Ultraschall-Schweissstege angeordnet;
  • c) der Querschnitt der Stegrahmen verjüngt sich zu einer Einschnürung ausgehend von den beiden Stirnflächen bis etwa zur halben Höhe der Stegrahmen;
  • d) die Scheiben weisen eine Wandstärke von weniger als 1 mm auf.
This object is achieved according to the invention by combining the following features:
  • a) the end edges of the web frames have outwardly projecting edge strips;
  • b) perpendicular to the end face formed by the end edges and edge strips, ultrasound welding webs running in the direction of the respectively adjacent pane are arranged;
  • c) the cross section of the web frame tapers to a constriction starting from the two end faces up to approximately half the height of the web frame;
  • d) the disks have a wall thickness of less than 1 mm.

Die erfinderische Tätigkeit ist darin zu sehen, dass sich die Stegrahmen mit ihren Randleisten gegenseitig abstützen und durch die Randleisten eine grossflächige Anlage gegenüber den Scheiben aufweisen. Durch die Ultraschallschweissung erhält man somit nicht nur eine Verbindung senkrecht zur Ebene der Scheiben, sondern auch eine formschlüssige Abstützung der Stegrahmen gegeneinander.The inventive step can be seen in the fact that the web frames are mutually supported with their edge strips and have a large-area contact with the panes due to the edge strips. The ultrasonic welding thus not only provides a connection perpendicular to the plane of the panes, but also a form-fitting support of the web frames against one another.

Im einzelnen füllen die Stegrahmen den Zwischenraum zwischen den beiden Platten oder Scheiben aus, indem die aneinanderstossenden Stegrahmen ein Gefach mit durchgehenden Trennwänden bilden. Die Stegrahmen sind rohrförmige Körper mit beliebigem Querschnitt; es können Kreiszylinder, elliptische Zylinder oder Mehrkant-, insbesondere Quadratrohre, sein. Die Zwischenschicht zwischen den beiden äusseren Scheiben wird so in eine Vielzahl kleiner Luftkammern unterteilt, so dass man eine kleine Wärmedurchgangszahl erhält. Die Randleisten stossen aneinander an und stellen eine definierte Ausrichtung der Stegrahmen im Zwischenraum zwischen den Scheiben sicher. Die Ultraschall-Richtstege garantieren eine hohe Festigkeit und Sicherheit der Ultraschall-Schweissverbindungen und eine gleichmässige Verbindung über die gesamte Fläche der Kunstglas-Isolierscheibe, so dass dieses zur Stabilität der Kunstglas-Isolierscheibe beiträgt. Die Kunstglas-Isolierscheibe besitzt ein gleiches Widerstandsmoment in Längsrichtung und in Querrichtung. Diese Konstruktion mit den Stegrahmen ermöglicht sehr dünne Wandstärke von weniger als 1 mm. Vorzugsweise beträgt die Wandstärke 0,5 mm.In particular, the web frames fill the space between the two plates or panes, in that the abutting web frames form a compartment with continuous partition walls. The web frames are tubular bodies with any cross-section; it can be circular cylinders, elliptical cylinders or polygonal, in particular square tubes. The intermediate layer between the two outer panes is divided into a large number of small air chambers so that a low heat transfer coefficient is obtained. The edge strips abut each other and ensure a defined alignment of the web frames in the space between the panes. The ultrasonic straightening bars guarantee high strength and security of the ultrasonic welding connections and a uniform connection over the entire surface of the synthetic glass insulating pane, so that this contributes to the stability of the synthetic glass insulating pane. The synthetic glass insulating pane has the same section modulus in the longitudinal and transverse directions. This construction with the web frame enables very thin walls of less than 1 mm. The wall thickness is preferably 0.5 mm.

Die Scheiben und Stegrahmen können aus einem schlagfesten glasklaren Kunststoff wie Polycarbonat, Polyester oder Polyvinylchlorid bestehen. Da die Stegrahmen aneinanderstossen und im Stossbereich gitterförmige Abstützungen bilden, ergibt sich eine sehr gute Einleitung von Kräften in den Aufbau, so dass die Stabilität ausserordentlich hoch ist. Dies ist für Bauteile, insbesondere freitragende Bauteile, wichtig. Man kann auch die Stegrahmen aus undurchsichtigem Werkstoff herstellen, um dadurch die Durchsichtigkeit der Kunstglas-Isolierscheibe zu ändern und den jeweiligen Wünschen anzupassen.The panes and web frames can be made of an impact-resistant, crystal-clear plastic such as polycarbonate, polyester or polyvinyl chloride. Since the web frames abut one another and form lattice-shaped supports in the joint area, forces are very well introduced into the structure, so that the stability is extraordinarily high. This is important for components, especially self-supporting components. It is also possible to manufacture the web frames from opaque material in order to change the transparency of the synthetic glass insulating pane and to adapt it to the respective requirements.

Nach einer Ausführungsform der Erfindung ist vorgesehen, dass die Stegrahmen einen zylindrischen Querschnitt aufweisen und deren Seitenwände die Seitenflächen eines Doppelkegelstumpfes bilden, dessen beide Kegelstümpfe mit den kleineren Stirnflächen zusammengesetzt sind. Diese Ausbildung nutzt die hohe Belastbarkeit eines Zylinders aus.According to one embodiment of the invention, it is provided that the web frames have a cylindrical cross section and the side walls of which form the side surfaces of a double truncated cone, the two truncated cones of which are assembled with the smaller end faces. This training takes advantage of the high resilience of a cylinder.

In weiterer Ausbildung der Erfindung ist vorgesehen, dass die Stegrahmen eine Vieleckform und in jedem Eckbereich Versteifungsstege haben, deren gerade Stirnkante senkrecht zu der Stirnfläche des Stegrahmens verlaufen. In weiterer Ausbildung der Erfindung ist vorgesehen, dass die Stegrahmen eine Quadratform haben, und dass im Eckbereich die Randleisten jeweils auf einer senkrecht zur Diagonalen ausgerichteten Linie in Höhe der Stirnkante des betreffenden Versteifungssteges abgeschnitten sind. Dadurch erreicht man eine besonders gleichmässige gegenseitige Abstützung und stabile Konstruktion.In a further embodiment of the invention it is provided that the web frames have a polygonal shape and stiffening webs in each corner region, the straight end edge of which runs perpendicular to the end face of the web frame. In a further embodiment of the invention it is provided that the web frames have a square shape and that in the corner area the edge strips are each cut off on a line oriented perpendicular to the diagonal at the front edge of the stiffening web in question. This provides a particularly uniform mutual support and stable construction.

In weiterer Ausbildung der Erfindung ist vorgesehen, dass auf den Seitenwänden weitere Versteifungsstege vorgesehen sind. Hierdurch wird die Stabilität der Stegrahmen erhöht.In a further embodiment of the invention it is provided that further stiffening webs are provided on the side walls. This increases the stability of the web frame.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass in halber Höhe jedes Stegrahmens in Höhe der Einschnürung eine Zwischenscheibe eingeformt ist. In dieser Ausbildung stellt die Erfindung eine Dreifachscheibe mit sehr hoher Wärmeisolierung bereit.According to a further development of the invention, it is provided that an intermediate disk is located halfway up each web frame at the level of the constriction is molded. In this embodiment, the invention provides a triple pane with very high thermal insulation.

In Weiterbildung der Erfindung wird vorgeschlagen, dass an einer Seitenwand des Stegrahmens eine zungenförmige Platte angeformt ist, deren Grösse etwa der Grösse der Stirnfläche des Stegrahmens gleich ist. Hierdurch ist gewährleistet, dass die Kunststoff-Isolierglasscheibe über ihre ganze Fläche eine Zwischenscheibe aufweist.In a development of the invention, it is proposed that a tongue-shaped plate is formed on a side wall of the web frame, the size of which is approximately the same as the size of the end face of the web frame. This ensures that the plastic insulating glass pane has an intermediate pane over its entire surface.

Schliesslich schlägt die Erfindung vor, dass die übrigen drei Seitenwände des Stegrahmens Nutleisten zur Aufnahme der zungenförmigen Platte aufweisen. Infolgedessen werden.die Ränder der zungenförmigen Platte geführt und gehalten, so dass der Zusammenhalt der Kunstglas-Isolierscheibe über ihre ganze Fläche sehr gut ist.Finally, the invention proposes that the remaining three side walls of the web frame have groove strips for receiving the tongue-shaped plate. As a result, the edges of the tongue-shaped plate are guided and held, so that the cohesion of the synthetic glass insulating pane is very good over its entire surface.

Damit die Kunstglas-Isolierscheibe einen direkten Einfall der Sonnenstrahlung oder einer anderen Strahlung ausschliesst, wird durch die Erfindung vorgeschlagen, dass die Achse der rohrförmigen Stegrahmen gegenüber den Stirnflächen geneigt ist. Die Kunstglas-Isolierscheibe muss dann beim Einbau so ausgerichtet werden, dass die Neigung der Achse entgegen der Einfallrichtung der Sonnenstrahlung ausgerichtet ist. Es ist dann eine blendfreie Belichtung gewährleistet. Die Höhe und Neigung der Stegrahmen muss so festgelegt sein, dass kein direkter Strahlungsdurchtritt möglich ist. Die Blendfreiheit ist insbesondere dann gewährleistet, wenn die Stegrahmen aus undurchsichtigem Werkstoff bestehen.So that the synthetic glass insulating pane precludes direct incidence of solar radiation or other radiation, the invention proposes that the axis of the tubular web frame is inclined with respect to the end faces. The synthetic glass insulating pane must then be aligned during installation so that the inclination of the axis is aligned with the direction of incidence of the solar radiation. A glare-free exposure is then guaranteed. The height and inclination of the frame must be set in such a way that direct radiation cannot pass through. The absence of glare is particularly guaranteed if the web frames are made of opaque material.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die Scheibe glasklar, die Stegrahmen eingetrübt oder undurchsichtig ausgebildet sind. Ferner schlägt die Erfindung vor, dass die obere Scheibe ganz oder teilweise eingetrübt oder undurchsichtig ausgebildet ist und die Öffnungen der Stegrahmen so abdeckt, dass kein direkter Lichtdurchfall möglich ist.According to a further feature of the invention, it is provided that the pane is crystal clear, the web frames are cloudy or opaque. Furthermore, the invention proposes that the upper pane is wholly or partially cloudy or opaque and covers the openings of the web frames in such a way that direct light transmission is not possible.

Durch die zuletzt genannten Ausbildungen wird es ermöglicht, dass die Kunstglas-Isolierscheibe den verschiedensten Anwendungsfällen angepasst werden kann.The training mentioned last makes it possible for the synthetic glass insulating pane to be adapted to a wide variety of applications.

Die Stegrahmen 3 bilden infolgedessen gemäss Fig. 2 ein schachgbrettartiges Muster. Auf beiden Stirnseiten der Stegrahmen 3 werden Scheiben 1 und 2 angeordnet. Es erfolgt eine flächenhafte Ultraschallschweissung, so dass sich die Stirnränder 6 fest mit den Scheiben 1 und 2 verbinden. Die Ultraschall-Richtstege 8 dienen zur Ausrichtung und Führung der Ultraschallenergie. Die Ultraschallschweissung kann in geeigneter Weise erfolgen, z.B. durch kontinuierliche Führung der Anordnung zwischen Ultraschall-Schweissköpfen. Die fertige Isolierscheibe enthält jeweils etwa würfelförmige Bereiche, die einerseits durch den Innenraum eines Stegrahmens und andererseits durch vier Seitenwände von vier aneinanderstossenden Stegrahmen abgeschlossen sind. Diese abgeschlossenen Räume bilden Luftpolster, so dass man sehr günstige Werte für die Wärmedurchgangszahl erhält. Infolge der abgeschlossenen Räume zwischen den beiden Scheiben 1 und 2 ist eine Luftzirkulation nicht möglich. Die Scheiben und Stegrahmen bestehen, wie bereits gesagt, aus Polycarbonat. Die Wandstärke der Teile beträgt jeweils 0,5 mm. Der Abstand der Scheiben 1 und 2 beträgt 40 mm. Auch die Kantenlänge eines Stirnrandes 6 beträgt 40 mm. Messungen ergaben für eine solche Kunstglas-Isolierscheibe eine Wärmedurchgangszahl k von 2,7 W/m2.The web frames 3 are assembled to form the complete synthetic glass insulating pane to form a surface-covering pattern, two adjacent web frames 3 each abutting one another with the diagonally cut lines 9. The web frames 3 consequently form a checkerboard-like pattern according to FIG. 2. Panes 1 and 2 are arranged on both end faces of the web frame 3. A two-dimensional ultrasonic welding takes place, so that the end edges 6 firmly connect to the panes 1 and 2. The ultrasonic straightening webs 8 are used to align and guide the ultrasonic energy. The ultrasonic welding can be carried out in a suitable manner, for example by continuously guiding the arrangement between ultrasonic welding heads. The finished insulating washer each contains approximately cube-shaped areas which are closed off on the one hand by the interior of a web frame and on the other hand by four side walls of four abutting web frames. These closed rooms form air cushions, so that you get very favorable values for the heat transfer coefficient. Due to the closed spaces between the two panes 1 and 2, air circulation is not possible. As already mentioned, the panes and web frames are made of polycarbonate. The wall thickness of the parts is 0.5 mm. The distance between disks 1 and 2 is 40 mm. The edge length of a front edge 6 is 40 mm. Measurements resulted in a heat transfer coefficient k of 2.7 W / m 2 for such a synthetic glass insulating pane.

Bei Bedarf kann man zusätzliche Versteifungsstege 10' verteilt über die Wände 4 anordnen, wie dies in der rechten Hälfte der Fig. 4 durch gestrichelte Linien angedeutet ist.If required, additional stiffening webs 10 'can be arranged distributed over the walls 4, as is indicated by dashed lines in the right half of FIG. 4.

Die Fig. 6 und 7 zeigen eine abgewandelte Ausführungsform der Erfindung, nämlich eine Dreifach-Isolierglasscheibe. Die Stegrahmen 3' entsprechen mit der Abwandlung den Stegrahmen 3, dass in der Höhe der Einschnürung 5 eine Zwischenscheibe 5 eingeformt ist, und ausserdem an einer Seitenwand 4' eine zungenförmige Platte 16 angeformt ist, deren Grösse etwa der Grösse der Stirnfläche des Stegrahmens 3' gleich ist. An den übrigen Seitenwänden 4" sind in Höhe der Einschnürung 5 Nutleisten angeformt, in denen die zungenförmigen Platten 16 benachbarter Stegrahmen 3' Aufnahme finden.6 and 7 show a modified embodiment of the invention, namely a triple insulating glass pane. The web frames 3 'correspond to the web frame 3 with the modification that an intermediate disc 5 is formed at the level of the constriction 5, and also a tongue-shaped plate 16 is formed on a side wall 4', the size of which approximately corresponds to the size of the end face of the web frame 3 ' is equal to. On the remaining side walls 4 "5 groove strips are formed at the level of the constriction, in which the tongue-shaped plates 16 of adjacent web frames 3 'are accommodated.

Der Zusammenhalt-dieser Kunstglas-Dreifachisolierscheibe ist aus den Fig. 6 und 7 ohne weiteres erkennbar. Die Stegrahmen 3' werden so zusammengefügt, dass jeweils eine zungenförmige Platte 16 eines Stegrahmens 3' mit ihren drei freien Kanten in Nutleisten 17 von drei benachbarten Stegrahmen 3' Aufnahme findet. Die freien Stirnflächen der Stegrahmen 3' sind durch Platten abgedeckt, die mit den Stegrahmen in der oben erläuterten Weise verschweisst werden. Man erhält so eine Kunstglas-Dreifachisolierscheibe mit einer durchgehenden Zwischenscheibe in halber Höhe, die durch die zungenförm,igen Platten 16 und die Zwischenscheibe 15 gebildet ist. Hierdurch wird die Wärmedurchgangszahl noch weiter verringert. Die dargestellten Stegrahmen sind Rohre mit quadratischem Querschnitt. Man kann auch Rohre mit beliebigen anderen Querschnitten vorsehen, z.B. Vieleckquerschnitt, Kreisquerschnitt und dergleichen.The cohesion of this triple insulating glass is easily recognizable from FIGS. 6 and 7. The web frames 3 'are joined in such a way that a tongue-shaped plate 16 of a web frame 3' with its three free edges is received in groove strips 17 of three adjacent web frames 3 '. The free end faces of the web frame 3 'are covered by plates which are welded to the web frame in the manner explained above. This gives a triple insulating glass pane with a continuous intermediate plate at half the height, which is formed by the tongue-shaped plates 16 and the intermediate plate 15. This further reduces the heat transfer coefficient. The web frames shown are tubes with a square cross section. Pipes with any other cross sections can also be provided, e.g. Polygonal cross-section, circular cross-section and the like.

Die bisher dargestellten Stegrahmen sind jeweils gerade Rohre, d.h. Rohre, die senkrecht zur Rohrachse abgeschnitten sind. Die Fig. 8 und 9 zeigen eine abgewandelte Ausführungsform, wonach die Stegrahmen 3' als schiefe Rohre mit quadratischem Querschnitt ausgebildet sind. Die beiden Seitenwände 21 verlaufen geneigt zu den Stirnflächen und die Seitenwände 22 haben Parallelogrammform. Alle Stegrahmen 3' sind mit gleicher Neigung der Seitenwände 21 angeordnet, wie man den Fig. 8 und 9 entnimmt. Die obere Scheibe 1 und die untere Scheibe 2 ist aufgelegt. Die Stegrahmen 3' bestehen insbesondere aus einem wenig durchscheinenden oder lichtundurchlässigen Werkstoff. Eine solche Kunstglas-Isolierscheibe wird so ausgerichtet, dass die Neigung der Seitenflächen 21 entgegen der Lichteinfallrichtung ausgerichtet ist. Ein unmittelbarer Lichtdurchtritt wird dann verhindert, so dass eine Blendung ausgeschlossen ist. Die Höhe des Stegrahmens und die Neigung der Seitenwände 21 muss in Abhängigkeit von dem zu erwartenden Sonnenstand bemessen sein.The web frames shown so far are each straight tubes, i.e. Pipes that are cut perpendicular to the pipe axis. 8 and 9 show a modified embodiment, according to which the web frames 3 'are designed as oblique tubes with a square cross section. The two side walls 21 are inclined to the end faces and the side walls 22 have a parallelogram shape. All web frames 3 'are arranged with the same inclination of the side walls 21, as can be seen in FIGS. 8 and 9. The upper disc 1 and the lower disc 2 are placed. The web frame 3 'consist in particular of a material which is not very translucent or opaque. Such a synthetic glass insulating pane is aligned so that the inclination of the side surfaces 21 is aligned against the direction of light incidence. An immediate passage of light is then prevented, so that glare is excluded. The height of the web frame and the inclination of the side walls 21 must be dimensioned depending on the expected position of the sun.

Die Lichteinfallverhältnisse und die Durchsichtigkeit der Kunstglas-Isolierscheibe können noch in anderer Weise beeinflusst werden. Man kann die in den Fig. 6 und 7 dargestellten Zwischenscheibe 15 und zungenförmigen Platten 16 so auslegen, dass nur ein Teil der freien Öffnungen abgedeckt ist. Die Kunstglas-Isolierscheibe wird dann so ausgerichtet, dass durch diese Zwischenscheibe oder zungenförmige Platte durchfallendes Licht abgeschirmt wird.The incidence of light and the transparency of the synthetic glass insulating pane can be influenced in another way. The intermediate disk 15 and tongue-shaped plates 16 shown in FIGS. 6 and 7 can be designed such that only a part of the free openings is covered. The synthetic glass insulating pane is then aligned in such a way that light falling through it is shielded by this intermediate pane or tongue-shaped plate.

Die Erfindung sieht ferner vor, dass die Scheibe gtaskiar, die Stegrahmen eingetrübt oder undurchsichtig ausgebildet sind. Schliesslich wird durch die Erfindung vorgesehen, dass die obere Scheibe ganz oder teilweise eingetrübt oder undurchsichtig ausgebildet ist und die Öffnungen der Stegrahmen so abdeckt, dass kein direkter Lichtdurchfall möglich ist. Bei der zuletzt beschriebenen Ausführungsform kann man die Undurchsichtigkeit der oberen Scheibe durch einen entsprechenden Aufdruck oder in anderer Weise bewirken.The invention further provides that the pane is gtaskiar, the web frame is cloudy or opaque. Finally, it is provided by the invention that the upper pane is completely or partially cloudy or opaque and covers the openings of the web frames in such a way that no direct light transmission is possible. In the last-described embodiment, the opacity of the upper pane can be brought about by appropriate printing or in some other way.
