Description

Die Erfindung betrifft eine Kunstglas-Isolierscheibe aus mindestens zwei Platten und Stegrahmen zwischen den Platten, deren Stegkanten mit den Platten verschweißt sind.The invention relates to an insulating glass pane made of at least two plates and a web frame between the plates, the web edges of which are welded to the plates.

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. A synthetic glass insulating pane of this type 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.

Aufgabe der Erfindung ist die Bereitstellung einer Kunstglas-Isolierscheibe, die bei geringer Wandstärke der einzelnen Platten ein gleichmäßig hohes Widerstandmoment in allen Richtungen und eine möglichst kleine Wärmedurchgangszahl hat.The object of the invention is to provide an insulating glass pane which, with a small wall thickness of the individual plates, has a uniformly high section modulus in all directions and a heat transfer coefficient that is as small as possible.

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

  • a) die Stegrahmen sind im wesentlichen als zylindrische Körper ausgebildet;
  • b) die Stirnränder der Stegrahmen besitzen nach außen überstehende Randleisten mit senkrecht zur Stirnfläche vorstehenden Ultraschallrichtstegen;
  • c) die Seitenwände der Stegrahmen bilden die Seitenflächen eines Doppelkegelstumpfes, dessen beide Kegelstümpfe mit den kleineren Stirnflächen zusammengesetzt sind.
This object is achieved according to the invention by combining the following features:
  • a) the web frames are essentially designed as cylindrical bodies;
  • b) the end edges of the web frames have outwardly protruding edge strips with ultrasonic straightening projections perpendicular to the end face;
  • c) the side walls of the web frames form the side surfaces of a Double truncated cone, the two truncated cones of which are composed with the smaller end faces.

Die Stegrahmen füllen den Zwischenraum zwischen den beiden Platten aus, indem die aneinanderstoßenden Stegrahmen ein Gefach mit durchgehenden Trennwänden bilden. Die Stegrahmen sind zylindrische Körper mit beliebigem Querschnitt; es können Kreiszylinder, elliptische Zylinder oder Zylinder mit Mehrkant-, insbesondere Quadratquerschnitt vorgesehen sein. Die Zwischenschicht zwischen den beiden äußeren Platten wird so in eine Vielzahl kleiner Kammern unterteilt, so daß man kleine Luftkammern und damit eine kleine Wärmedurchgangszahl erhält. Die Ultraschallrichtstege garantieren eine hohe Festigkeit und Sicherheit der Ultraschallschweißverbindungen 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 Widerstandmoment 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.The web frames fill the space between the two plates, in that the abutting web frames form a compartment with continuous partitions. The web frames are cylindrical bodies with any cross-section; circular cylinders, elliptical cylinders or cylinders with a polygonal, in particular square, cross section can be provided. The intermediate layer between the two outer plates is divided into a large number of small chambers, so that small air chambers and thus a small heat transfer coefficient are obtained. 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 a very thin wall thickness of less than 1 mm. The wall thickness is preferably 0.5 mm.

Die Platten und Stegrahmen können aus einem schlagfesten glasklaren Kunststoff wie Polycarbonat, Polyester pder 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 plates 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 extremely 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.

In weiterer Ausbildung der Erfindung haben die Stegrahmen eine Vieleckform und mindestens in jedem Eckbereich sind Versteifungsstege mit gerader Stirnkante vorgesehen. In weiterer Ausbildung der Erfindung ist vorgesehen, daß die Stegrahmen eine Quadratform haben und daß im Stoßbereich 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 und stabile Konstruktion.In a further embodiment of the invention, the web frames have a polygonal shape and stiffening webs with a straight end edge are provided at least in each corner area. In a further embodiment of the invention it is provided that the web frames have a square shape and that in the joint 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 results in a particularly uniform 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 der Doppelpyramidenstumpfform eine Zwischenplatte eingeformt ist. In dieser Ausbildung stellt die Erfindung eine Dreifachscheibe mit sehr hoher Wärmeisolierung bereit.According to a development of the invention it is provided that in an intermediate plate is molded in half the height of each web frame at the level of the constriction of the double pyramid frustum. 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 zungenfönnige 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 Zwischenplatte 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 plate 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 Flächr sehr gut ist. Damit die Kunstglas-Isolierscheibe einen direkten Einfall der Sonnenstrahlung oder einer anderen Strahlung ausschließt, wird durch die Erfindung vorgeschlagen, daß die Stegrahmen eine schiefe Zylinderform aufweisen, wobei die Achse gegenüber den Stirnflächen geneigt ist. Die Kunstglas-Isolierscheibe muß dann beim Einbau so ausgerichtet werden, daß die Neigung der Zylinderachse 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 Stegrah- ) men aus undurchsichtigem Werkstoff bestehen.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 area. So that the synthetic glass insulating pane precludes direct incidence of solar radiation or other radiation, the invention proposes that the web frames have an oblique cylindrical shape, the axis being inclined relative to the end faces. The synthetic glass insulating pane must then be aligned during installation so that the inclination of the cylinder axis is aligned against the direction of incidence of 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 Platten glasklar, die Stegrahmen eingetrübt oder undurchsichtig ausgebildet sind. Ferner schlägt die Erfindung vor, daß die obere Platte 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 plates are crystal clear, the web frames are cloudy or opaque. Furthermore, the invention proposes that the upper plate is wholly or partially cloudy or opaque and covers the openings of the web frame so that no direct light transmission is possible.

Durch die zuletzt genannten Ausbildungen wird es ermöglicht, daß die Kunstglas-Isolierscheibe den verschiedensten Anwendungsfällen angepaßt werden kann.The last-mentioned training enables the synthetic glass insulating pane to be adapted to a wide variety of applications.

Der Schnitt durch die Isolierscheibe gemäß Fig. 1 zeigt eine obere Platte 1 und eine untere Platte 2, zwischen denen Stegrahmen 3 angeordnet sind. Alle Teile bestehen aus Polycarbonat. Die Platten können eine den jeweiligen Belastungsverhältnissen angepaßte Wandstärke aufweisen. Die Wandstärke der Platten kann bis auf 0,5 mm oder weniger herabgesetzt werden.The section through the insulating washer according to FIG. 1 shows an upper plate 1 and a lower plate 2, between which web frames 3 are arranged. All parts are made of polycarbonate. The plates can have a wall thickness adapted to the respective load conditions. The wall thickness of the panels can be reduced to 0.5 mm or less.

Zunächst wird der Aufbau eines Stegrahmens anhand der Fig. 3 bis 5 erläutert. Jeder Stegrahmen ist ein Kunststoffspritzgießteil in Zylinderform. Der dargestellte Stegrahmen ist ein Zylinder mit quadratischem Querschnitt und umfaßt vier Seitenwände 4, die so gegeneinander geneipt sind, daß sie die Seitenflächen eines Doppelkegelstumpfes mit einer Einschnürung 9 in halber Höhe des Stegrahmens 3 bilden. Der Kegelstumpf hat einen quadratischen Querschnitt. An den offenen Stirnseiten sind umlaufende Stirnränder 6 mit verbreiterter Auflagefläche 7 vorgesehen. Innerhalb dieser Auflagefläche 7 sind Ultraschallrichtstege 8 ausgebildet. Im Eckbereich sind die Randleisten jeweils auf einer Linie 9 abgeschnitten, die senkrecht zur Diagonalen des Stegrahmens und der Stirnfläche ausgerichtet ist. Außerdem sind mindstens im Eckbereich Versteifungsstege 10 vorgesehen, deren Stirnkanten senkrecht zu den Stirnflächen der Stegrahmen ausgerichtet sind und mit der abgeschnittenen Linie 0 jeweils abschließen.First, the structure of a web frame is explained with reference to FIGS. 3 to 5. Each frame is a plastic injection molded part in the shape of a cylinder. The web frame shown is a cylinder with a square cross-section and comprises four side walls 4, which are so inclined against each other that they form the side surfaces of a truncated cone with a constriction 9 halfway up the web frame 3. The truncated cone has a square cross section. Circumferential end edges 6 with widened contact surface 7 are provided on the open end faces. Ultrasonic straightening webs 8 are formed within this support surface 7. In the corner area, the edge strips are each cut off on a line 9, which is aligned perpendicular to the diagonal of the web frame and the end face. In addition, stiffening webs 10 are provided at least in the corner area, the end edges of which are aligned perpendicular to the end faces of the web frame and each end with the cut line 0.

Zu der vollständigen Kunstglas-Isolierscheibe werden die Stegrahmen 3 zu einen flächendeckenden Muster zusammengesetzt, wobei jeweils zwei benachbarte Stegrahmen 3 mit den diagonal abgeschnitten Linien 9 aneinanderstoßen. Die Stegrahmen 3 bilden infolgedessen gemäß Fig. 2 ein schachbrettartiges Muster. Auf beiden Stirnseiten der Stegrahmen 3 werden Platten 1 und 2 angeordnet. Es erfolgt eine flächenhafte Ultraschallschweißung, so daß sich die Stirnränder 6 fest mit den Platten 1 und 2 verbinden. Die Ultraschallrichtstege 8 dienen zur Ausrichtung und Führung der Ultraschallenergie. Die Ultraschallschweißung kann in geeigneter Weise erfolgen, z.B. durch kontinuierliche Führung der Anordnung zwischen Ultraschallschweißköpfen. 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. Durch die angeschlossenen Räume zwischen den beiden Platten 1 und 2 ist eine Luftzirkulation zwischen diesen Platten 1 und 2 nicht möglich. Die Platten und Stegrahmen bestehen, wie bereits gesagt, aus Polycarbonat. Die Wandstärke der Teile beträgt jeweils 0,5 mm. Der Abstand der Platten 1 und 2 beträgt 40 mm. Auch die Kantenlänge eines Stirnrandes 6 beträgt 40 mm. Messungen ergaben für eine solche Kunstglas-Isolierscheibe eine Wärmedurchgangszahl von 2,7

.To form the complete synthetic glass insulating pane, the web frames 3 are put together 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. Panels 1 and 2 are arranged on both end faces of the web frame 3. There is an areal ultrasonic welding, so that the front edges 6 firmly with the Connect plates 1 and 2. The ultrasonic straightening webs 8 serve 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 contains approximately cube-shaped areas which are closed 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 connected spaces between the two plates 1 and 2, air circulation between these plates 1 and 2 is not possible. As already mentioned, the plates and web frames are made of polycarbonate. The wall thickness of the parts is 0.5 mm each. The distance between the plates 1 and 2 is 40 mm. The edge length of a front edge 6 is 40 mm. Measurements resulted in a heat transfer coefficient of 2.7 for such a synthetic glass insulating pane

An den übrigen Seitenwinden 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 frame 3 'correspond with the modification of the web frame 3 that an intermediate plate 15 is formed in the height of the constriction 5 and also a tongue-shaped plate 16 is formed on a side wall 4', the size of which is approximately the same as the size of the end face of the web frame 3 ' is. On the other side winches 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 Zwischenplatte in halber Höhe, die durch die zungenförmigen Platten 16 und die Zwischenplatten 15 gebildet ist. Hierdurch wird die Wärmedurchgangszahl noch weiter verringert. Die dargestellten Stegrahmen sind Zylinder mit quadratischem Querschnitt. Man kann auch Zylinder mit beliebigen anderen Querschnitten vorsehen, z.B. Vieleckquerschnitt, Kreisquerschnitt und dergleichen. Die bisher dargestellten Stegrahmen sind jeweils gerade Zylinder. Die Fig. 8 und 9 zeigen eine abgewandelte Ausführungsform, wonach die Stegrahmen 3' als schiefe Zylinder mit quadratischem Querschnitt ausgebildet sind. Die beiden Seitenwände 21 verlaufen geneigt zu den Stirnflächen und die Seitenwände 22 haben Parallelogrammform. Alle Stegrah-nen 3' sind mit gleicher Neigung der Seitenwände 21 angeordnet, wie man den Fig. 8 und 9 entnimmt. Die obere Platte 1 und die untere Platte 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 erwarteten Sonnenstand bemessen sein.The cohesion of this triple insulating glass is easily recognizable from FIGS. 6 and 7. The web frames 3 'are put together 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 height, which is formed by the tongue-shaped plates 16 and the intermediate plates 15. This further reduces the heat transfer coefficient. The web frames shown are cylinders with a square cross-section. It is also possible to provide cylinders with any other cross sections, for example polygonal cross section, circular cross section and the like. The web frames shown so far are each straight cylinders. 8 and 9 show a modified embodiment, according to which the web frames 3 'are designed as oblique cylinders 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 plate 1 and the lower plate 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 Fi1. 6 und 7 dargestellten Zwischenplatten 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 Zwischenplatte 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. You can see that in Fi 1 . 6 and 7 shown intermediate plates 15 and tongue-shaped plates 16 so that only a part of the free openings is covered. The art of glass - insulating disk is then aligned so that transmitted light is shielded by this intermediate plate or tongue-shaped plate.

Die Erfindung sieht ferner vor, daß die Platten glasklar, die Stegrahmen eingetrübt oder undurchsichtig ausgebildet sind. Schließlich wird durch die Erfindung vorgesehen, daß die obere Platte ganz oder teilweise eingetrübt oder undurchsichtig ausgebildet ist und die Öffnungen der Stegrahmen so abdeckt, daß keine direkter Lichtdurchfall möglich ist. Bei der zuletzt beschriebenen Ausführungsform kann man die Undurchsichtigkeit der oberen Platte durch einen entsprechenden Aufdruck oder in anderer Weise bewirken.The invention further provides that the plates are crystal clear, the web frame is cloudy or opaque. Finally, it is provided by the invention that the upper plate is completely or partially cloudy or opaque and covers the openings of the web frames so that no direct light transmission is possible. In the last-described embodiment, the opacity of the top plate can be achieved by appropriate printing or in another way.
