Abstract

An arrangement for attaching panes to glazing bars for the purpose of forming glazed roofs, facings, etc. possesses glazing bars composed of wood or glue binder and in each case consisting of a glazing-bar lower part and a glazing-bar head (10) detachably connected thereto, the panes (16, 18) being arranged between glazing-bar lower part (4) and glazing-bar head (10), with interposed seals (20, 21, 22, 23). The formation of thermal bridges is thereby prevented. <IMAGE>

Description

Die Erfindung betrifft einen Holz- oder Leimbindersparren für Glasüberdachungen gemaß Oberbegriff des Anspruchs 1.The invention relates to a wooden or glued truss rafters for glass roofs according to the preamble of claim 1.

Bei herkömmlichen Glasüberdachungen werden die Glasscheiben mit Hilfe von Metalleisten und Gummidichtungen gefaßt, wobei die Metalleisten auf den Sparren aufgeschraubt werden. Diese Metalleisten stellen thermische Brücken dar, d. h. Kältebrücken, durch die sich in den Hohlräumen zwischen den beiden Metalleisten und um die Glasscheibe in diesem Bereich Kondenswasser bildet. Für dieses Kondenswasser muß eine gesonderte Entwässerung vorgesehen werden; außerdem besteht durch dieses Kondenswasser die Gefahr von Korrosionen. Durch die thermischen Brücken besteht ferner die Gefahr von Hitzestaus und der Entstehung von nachteiligen thermischen Spannungen.In conventional glass roofs, the glass panes are gripped with the aid of metal strips and rubber seals, the metal strips being screwed onto the rafters. These metal strips represent thermal bridges, i. H. Cold bridges, through which condensation forms in the cavities between the two metal strips and around the glass pane in this area. Separate drainage must be provided for this condensed water; there is also a risk of corrosion from this condensation. Due to the thermal bridges there is also the risk of heat build-up and the development of disadvantageous thermal stresses.

Aus der GB-A-480124 sind Verglasungsleisten mit einer unteren Leiste und einer Kopfleiste bekannt. Die untere Leiste ist mit einem oberseitigen mittleren Steg versehen, der in einer mittigen Nut der Kopfleiste angeordnet und mit der Kopfleiste verschraubbar ist. Beiderseits des Steges sind zwischen Kopfleiste und unterer Leiste Nuten gebildet zur Aufnahme der Ränder von Glasscheiben unter Belassung von Freiräumen als Hinterlüftungsräume zwischen Glasscheibenrand und Steg und unter Zwischenschaltung elastischer Dichtungen zwischen der Kopfleiste und den Glasscheiben. Beiderseits des mittleren Steges sind rinnenartige Vertiefungen ausgebildet, die mit den Freiräumen in Verbindung stehen.From GB-A-480124 glazing bars with a lower bar and a head bar are known. The lower bar is provided with an upper middle web, which is arranged in a central groove of the head bar and can be screwed to the head bar. Grooves are formed on both sides of the web between the top bar and the bottom bar to accommodate the edges of glass panes while leaving free space as ventilation spaces between the glass pane edge and the web and with the interposition of elastic seals between the header and the glass panes. Trough-like depressions are formed on both sides of the central web, which are connected to the free spaces.

Die Aufgabe der vorliegenden Erfindung besteht darin, bei einem Holz- oder Leimbindersparren der eingangs genannten Art die Abdichtung zu verbessern, um der Gefahr eines Eindringens von Wasser zu begegnen, und die Entstehung von Kondenswasser zu verhindern.The object of the present invention is to improve the seal in a wooden or glue-rafter of the type mentioned in order to counter the risk of water penetration and to prevent the formation of condensed water.

Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst.This object is achieved by the invention specified in claim 1.

Eine vorteilhafte und zweckmäßige Weiterbildung der Erfindung ist im Unteranspruch angegeben.An advantageous and expedient development of the invention is specified in the subclaim.

Die Erfindung setzt Mittel zur Befestigung von Glasscheiben an Holz- oder Leimbindersparren ein, bei denen auf Metalle oder ähnliche thermisch gut leitende Materialien verzichtet wird. Es sind keine thermischen Brücken mehr vorhanden, weil die Befestigung der Scheiben ausschließlich über Materialien wie Gummi und Holz erfolgt. Dies bedeutet, daß die Gefahr der Entstehung von Kondenswasser, von Korrosionen und von Hitzestaus verringert ist. Außerdem können nachteilige thermische Spannungen nicht mehr auftreten. Durch die Dichtungsstreifen sowohl zwischen der Glasscheibe und dem Sparrenunterteil als auch zwischen der Glasscheibe und dem Sparrenkopf und durch die kappenförmige Abdeckung mit seitlichen Regenrinnen wird eine verbesserte Abdichtung erzielt.The invention uses means for fastening glass panes to wooden or glue-rafters, in which metals or similar thermally highly conductive materials are dispensed with. There are no longer any thermal bridges because the panes are only attached using materials such as rubber and wood. This means that the risk of condensation, corrosion and heat build-up is reduced. In addition, adverse thermal stresses can no longer occur. The sealing strips between the glass pane and the lower part of the rafters as well as between the glass pane and the rafters head and the cap-shaped cover with side gutters improve the seal.

Die Erfindung soll nachfolgend anhand der beigefügten Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, näher erläutert werden.The invention will be explained below with reference to the accompanying drawing, in which an embodiment is shown.

Die Zeichnung zeigt einen Sparren 2 mit einem Sparrenunterteil 4, das oberseitig in seiner Längserstreckung beidseitig stufenförmige Ausnehmmungen 6, 7 aufweist, zwischen denen ein mittiger Steg 8 belassen ist. Auf dem Steg 8 ist ein den Steg 8 beidseitig überragender Sparrenkopf 10 befestigt, beispielsweise mit Hilfe von Verschraubungen 12. Auf diese Weise werden zwischen dem Sparrenkopf 10 und den Stufen 14, 15 der Ausnehmungen 6, 7 längsverlaufende Nuten gebildet, in die Glasscheiben 16, 18 eingesetzt sind. Die Nuten befinden sich vorzugsweise im oberen Drittel des Gesamtsparrens 2.The drawing shows a rafters 2 with a lower rafters part 4, the longitudinal extension of which has step-shaped recesses 6, 7 on both sides, between which a central web 8 is left. On the web 8, a rafter head 10 protruding on both sides of the web 8 is fastened, for example with the aid of screw connections 12. In this way, longitudinal grooves are formed between the rafter head 10 and the steps 14, 15 of the recesses 6, 7, into the glass panes 16, 18 are used. The grooves are preferably located in the upper third of the overall rafter 2.

Ober- und unterseitig der Glasscheiben befinden sich zwischen den Glasscheiben und dem Sparrenkopf und den Stufen Gummilippendichtungen 20, 21, 22, 23.Upper and lower sides of the glass panes are located between the glass panes and the rafter head and the steps rubber lip seals 20, 21, 22, 23.

Zwischen den Glasscheiben und dem Steg 8 sind Hinterlüftungen 24, 26 vorgesehen. Diese Hinterlüftungen werden noch dadurch verbessert, daß wenigstens eine der beidseitigen Dichtungen, vorzugsweise die unteren Dichtungen 21, 23 mit Abstand vor dem Steg 8 enden. Zusätzlich können die Stufen 14, 15 am Übergang zum Steg 8 eine rinnenartige Vertiefung 28 bzw. 30 aufweisen.Ventilations 24, 26 are provided between the glass panes and the web 8. These rear vents are further improved in that at least one of the seals on both sides, preferably the lower seals 21, 23, end at a distance from the web 8. In addition, the steps 14, 15 can have a groove-like depression 28 or 30 at the transition to the web 8.

Der Sparrenkopf 10 weist eine kappenförmige Abdeckung 32, beispielsweise aus Kupfer, Zinkblech, Alu oder Kunststoff, auf. Die Abdeckung kann mit seitlichen Regenrinnen 34, 36 versehen sein.The rafter head 10 has a cap-shaped cover 32, for example made of copper, zinc sheet, aluminum or plastic. The cover can be provided with lateral gutters 34, 36.

Wenn der Sparren 2 zur Aufnahme von nur einer Glasscheibe vorgesehen ist, so weist das Sparrenunterteil 4 nur eine seitliche Ausnehmung auf.If the rafters 2 are provided for receiving only one glass pane, the rafters lower part 4 has only one lateral recess.

Der Sparren 2 mit Sparrenunterteil 4 und Sparrenkopf 10 besteht aus Vollholz oder geleimtem Holz.The rafters 2 with rafters lower part 4 and rafters head 10 are made of solid wood or glued wood.
