Description

Die Erfindung betrifft ein Verfahren zum Verlegen von mit einer massgenauen Umrahmung aus einem Kunststoff versehenen Glasbausteinen innerhalb einer Maueröffnung. Sie umfasst ferner einen nach diesem Verfahren in eine Maueröffnung eingesetzten Wandteil aus mit massgenauen Umrahmungen aus Kunststoff versehenen Glasbausteinen sowie ein für die Durchführung des Verfahrens besonders geeignetes, aus Profilstäben und Profilstababschnitten bestehendes Montagesystem.The invention relates to a method for laying glass blocks provided with a dimensionally accurate frame made of a plastic within a wall opening. It also comprises a wall part made of glass blocks provided with dimensionally accurate frames made of plastic and a mounting system consisting of profile bars and profile bar sections which is particularly suitable for carrying out the method.

Glasbausteine mit einer massgenauen Umrahmung aus Kunststoff sind z. B. aus der DE-A Nr. 2263127 grundsätzlich bekannt. Beim Verlegen dieser bekannten Glasbausteine, d. h. beim Aufbau eines Wandteils aus diesen Glasbausteinen, werden diese unter Zwischenschaltung eines Klebers an den Umfangsflächen miteinander verklebt. Dabei sorgt der Kleber sowohl für den Zusammenhalt der Glasbausteine als auch für die gegenseitige Abdichtung.Glass blocks with a dimensionally accurate frame made of plastic are e.g. B. basically known from DE-A No. 2263127. When laying these known glass blocks, i. H. When building a wall part from these glass blocks, these are glued to one another on the peripheral surfaces with the interposition of an adhesive. The adhesive ensures that the glass blocks are held together and that they seal against each other.

Es sind jedoch auch bereits Glasbausteine mit einer massgenauen Umrahmung aus Kunststoff vorgeschlagen worden, die dank einer besonderen Ausgestaltung ihrer Umfangsflächen und dank der besonderen Eigenschaften des die Umrahmung bildenden Kunststoffs ohne Zwischenschaltung einer Kleberschicht verlegt werden können (DE-A Nr.3233470).However, glass blocks with a dimensionally accurate frame made of plastic have also been proposed which, thanks to a special design of their peripheral surfaces and thanks to the special properties of the plastic forming the frame, can be installed without the interposition of an adhesive layer (DE-A No. 3233470).

Es ist auch bekannt, ein Wandelement zwischen starren Flächen mittels Keilen zu halten (GB-A Nr. 1190086)It is also known to hold a wall element between rigid surfaces by means of wedges (GB-A No. 1190086)

Insbesondere in solchen Fällen, in denen aus derartigen Glasbausteinen bestehende Wandteile eine hohe mechanische Festigkeit aufweisen sollen, oder eine besonders hohe Dichtigkeit in den Stossfugen erwünscht ist, d. h. wenn derartige Glasbausteine in Aussenwänden eingesetzt werden sollen, reichen die bekannten Methoden zum Verlegen solcher Glasbausteine nicht aus.In particular in those cases in which wall parts consisting of such glass blocks are to have a high mechanical strength, or a particularly high level of tightness in the butt joints is desired, i. H. If such glass building blocks are to be used in external walls, the known methods for laying such glass building blocks are not sufficient.

Der Erfindung liegt demgernäss die Aufgabe zugrunde, ein Verfahren zum Verlegen solcher Glasbausteine zu schaffen, das es erlaubt, Wandteile mit hoher mechanischer Belastbarkeit und hoher Dichtigkeit gegenüber Wasser und Feuchtigkeit zu erstellen, die auch den an Aussenwände gestellten Bedingungen genügen. Das erfindungsgemässe Verfahren soll insbesondere das Verlegen der Glasbausteine mit einem gezielten Anpressdruck innerhalb der Glasbausteinreihen erlauben.The invention is therefore based on the object to provide a method for laying such glass blocks, which allows to create wall parts with high mechanical strength and high tightness against water and moisture, which also meet the conditions placed on the outer walls. The method according to the invention is intended, in particular, to allow the glass blocks to be laid with a targeted contact pressure within the rows of glass blocks.

Das Verfahren nach der Erfindung zeichnet sich dadurch aus, dass nach dem Zusammensetzen einer Reihe von Glasbausteinen wenigstens auf einer Seite der Steinreihe zwischen dem äussersten Glasbaustein und dem angrenzenden Mauerwerk ein die Höhe eines umrahmten Glasbausteins aufweisender Keil seitlich gegen die Umrahmung des Glasbausteins gestellt und durch Eintreiben eines mit diesem Keil zusammenwirkenden zweiten Keils zwischen den Keil und das Mauerwerk die Glasbausteine innerhalb dieser Steinreihe zusammengepresst werden.The method according to the invention is characterized in that after assembling a row of glass blocks at least on one side of the row of stones between the outermost glass block and the adjacent masonry, a wedge having the height of a framed glass block is placed laterally against the frame of the glass block and driven in a second wedge interacting with this wedge between the wedge and the masonry, the glass blocks within this row of stones are pressed together.

Das verwendete Keilpaar besteht in Weiterbildung der Erfindung aus einem Material, das höchstens dieselbe Druckfestigkeit aufweist wie der die Umrahmung der Glasbausteine bildende Kunststoff. Vorzugsweise wird für diese Kraftkeile ein Material verwendet, das eine geringere Druckfestigkeit aufweist als der die Umrahmung der Glasbausteine bildende Kunststoff. Statt dessen können die Kraftkeile selbst auch aus einem Werkstoff mit einer im Vergleich zu der Druckfestigkeit der Umrahmung höheren Druckfestigkeit bestehen, und zwischen den Kraftkeilen und den angrenzenden Glasbausteinen Zwischenkörper mit einer im Vergleich zu der Druckfestigkeit der Umrahmung geringeren Druckfestigkeit zwischengeschaltet werden.In a further development of the invention, the pair of wedges used consists of a material which has at most the same compressive strength as the plastic forming the frame of the glass blocks. A material which has a lower compressive strength than the plastic forming the frame of the glass blocks is preferably used for these power wedges. Instead, the force wedges themselves can also be made of a material with a higher compressive strength compared to the compressive strength of the frame, and intermediate bodies with a lower compressive strength compared to the compressive strength of the frame can be interposed between the force wedges and the adjacent glass blocks.

Durch die erfindungsgemässen Massnahmen lassen sich Glasbausteinwände mit einem gezielten Anpressdruck der Glasbausteine untereinander verlegen. Dabei wird es durch die Verwendung von Keilpaaren zur Erzeugung des gewünschten Anpressdruckes möglich, auch unterschiedliche seitliche Abstände zu der angrenzenden Wand der Maueröffnung zu überbrücken. In den meisten Fällen genügt es dabei, lediglich die horizontalen Steinreihen auf diese Weise unter Vorspannung zu verlegen, während der erforderliche Anpressdruck innerhalb der vertikalen Steinreihen durch das Eigengewicht der Glasbausteine gegeben ist. Ggf. lässt sich jedoch eine zusätzliche Anpressung auch in senkrechter Richtung auf die erfindungsgemässe Weise erreichen.The measures according to the invention allow glass block walls to be laid with one another with a targeted contact pressure of the glass blocks. The use of wedge pairs to generate the desired contact pressure makes it possible to bridge different lateral distances from the adjacent wall of the wall opening. In most cases, it is sufficient to lay the horizontal stone rows in this way with prestressing, while the required contact pressure within the vertical stone rows is given by the weight of the glass blocks. Possibly. However, an additional contact can also be achieved in the vertical direction in the manner according to the invention.

Die Aussenabmessungen der Umrahmung 3 haben enge Masstoleranzen, so dass die miteinander zusammenwirkenden Flächen sich dicht gegeneinander legen, und die Verbindungsvorsprünge bzw. -vertiefungen nach dem Zusammenstecken einen festen Sitz gewährleisten.The frame 3 is arranged as a closed, dimensionally accurate frame on the entire peripheral surface of the glass body 1. The outer dimensions of the frame 3 have narrow dimensional tolerances, so that the surfaces interacting with one another lie tightly against one another, and the connecting projections or recesses ensure a firm fit after being plugged together.

Die Herstellung der Umrahmung 3 erfolgt in an sich bekannter Weise nach dem sogenannten Reaktions-Schaum-Giessverfahren, das auch als RIM-Verfahren (Reaction-Injection-Molding) bekannt ist. Dabei wird der Kunststoff in flüssiger Form innerhalb eines entsprechend gestalteten Formwerkzeugs auf die Umfangsfläche des Glaskörpers 1 aufgespritzt. Der Kunststoff härtet in dem Formwerkzeug aus, so dass dem Formwerkzeug der fertig umrahmte Glasbaustein entnommen wird.The frame 3 is produced in a manner known per se according to the so-called reaction foam casting process, which is also known as the RIM process (reaction injection molding). In this case, the plastic is sprayed in liquid form onto the peripheral surface of the glass body 1 within a correspondingly designed molding tool. The plastic hardens in the mold, so that the framed glass block is removed from the mold.

Die Umrahmung 3 weist eine dichte und dauerhafte Verbindung mit der Glasoberfläche auf. Insbesondere unter dem Gesichtspunkt der im allgemeinen stark unterschiedlichen Wärmeausdehnungskoeffizienten von Glas- und Kunststoff kommt der Verbindung des Kunststoffs mit der Glasoberfläche eine besondere Bedeutung zu. Zur Erhöhung der Haftung des Kunststoffs an der Glasoberfläche werden deshalb auf den jeweiligen Kunststoff abgestimmte Haftverbesserer oder Primer angewendet, die vor dem Einlegen des Glaskörpers in das Formwerkzeug auf die Umfangsfläche des Glaskörpers aufgebracht werden. Solche Haftverbesserer sind handelsüblich und werden entsprechend dem für die Umrahmung verwendeten Kunststoff ausgewählt.The frame 3 has a tight and permanent connection to the glass surface. Particularly from the point of view of the generally very different coefficients of thermal expansion of glass and plastic, the connection of the plastic to the glass surface is of particular importance. To increase the adhesion of the plastic to the glass surface, adhesion promoters or primers matched to the respective plastic are therefore used, which are applied to the peripheral surface of the glass body before the glass body is inserted into the mold. Such adhesion promoters are commercially available and are selected in accordance with the plastic used for the framing.

Zur weiteren Haftverbesserung der Umrahmung 3 auf dem Glaskörper 1 ist die Umfangsfläche 4 derart aufgerauht bzw. mit einer Struktur 9 versehen, dass die mit dem Kunststoff der Umrahmung in Kontakt stehende Oberfläche etwa dreimal grösser ist als im glatten Zustand. Diese gezielte Vergrösserung der Glasoberfläche wird durch entsprechende Gestaltung der Formwände der Pressformen erreicht, mit denen die Halbsteine 1a, 1 b gepresst werden. Eine ausreichende Vergrösserung der Glasoberfläche lässt sich durch eine Riffelung, Nörpelung oder sonstige Aufrauhung der Wand der Pressform erreichen.To further improve the adhesion of the frame 3 on the glass body 1, the peripheral surface 4 is roughened or provided with a structure 9 that the surface in contact with the plastic of the frame is approximately three times larger than in the smooth state. This targeted enlargement of the glass surface is achieved by appropriate design of the mold walls of the press molds with which the half-stones 1a, 1b are pressed. A sufficient enlargement of the glass surface can be achieved by corrugation, corrugation or other roughening of the wall of the press mold.

Die Umrahmung 3 weist eine zentrale ebene Begrenzungsfläche 5, seitliche Dichtvorsprünge 6, Verbindungsvorsprünge 10 und Verbindungsausnehmungen 12 auf.The frame 3 has a central flat boundary surface 5, lateral sealing projections 6, connecting projections 10 and connecting recesses 12.

Die Dichtvorsprünge 6 bilden jeweils zwei ebene Dichtflächen 7, die durch eine nutförmige Vertiefung 8 voneinander getrennt sind. Jede Dichtfläche 7 hat eine Breite B von etwa 3 bis 4 mm, und die nutförmige Vertiefung 8 hat eine Breite b von 1 bis 3 mm, vorzugsweise von etwa 2 mm. Durch diese Gestaltung der Dichtvorsprünge wird eine einer Labyrinthdichtung ähnliche Dichtung mit besonders günstigen Dichteigenschaften geschaffen. Die nutförmigen Vertiefungen 8 der nebeneinander angeordneten Glasbausteine in einem aus diesen Glasbausteinen aufgebauten Wandteil stehen miteinander in Verbindung, und die senkrecht verlaufenden nutförmigen Vertiefungen 8 bilden gewissermassen rinnenartige Hohlräume, durch die ggf. durch die erste Dichtfläche eingedrungenes Wasser ablaufen kann.The sealing projections 6 each form two flat sealing surfaces 7, which are separated from one another by a groove-shaped recess 8. Each sealing surface 7 has a width B of approximately 3 to 4 mm, and the groove-shaped recess 8 has a width b of 1 to 3 mm, preferably approximately 2 mm. This design of the sealing projections creates a seal similar to a labyrinth seal with particularly favorable sealing properties. The groove-shaped recesses 8 of the glass blocks arranged next to one another in a wall part constructed from these glass blocks are connected to one another, and the perpendicularly extending groove-shaped recesses 8 form, as it were, groove-like cavities through which water which has possibly penetrated through the first sealing surface can run off.

Falls ganz besonders hohe Anforderungen an die Dichtigkeit der Glasbausteinwand gestellt werden, wie es beispielsweise der Fall ist, wenn ein Druckunterschied zwischen den durch die Glasbausteinwand voneinander getrennten Räumen besteht, kann es sich empfehlen, zur zusätzlichen Sicherung in eine der nutförmigen Vertiefungen 8 eine elastische Dichtschnur 16 einzulegen. Hierfür lassen sich beispielsweise im Handel erhältliche Dichtschnüre aus Butylkautschuk verwenden.If very high demands are placed on the tightness of the glass brick wall, as is the case, for example, if there is a pressure difference between the spaces separated by the glass brick wall, it may be advisable to add an elastic sealing cord to one of the groove-shaped recesses 8 for additional securing 16 to insert. For this purpose, commercially available sealing cords made of butyl rubber can be used.

Die Verbindungsvorsprünge 10 haben die Form von Kreiszylindern. Ihr Durchmesser d beträgt etwa 40 mm bei einer Gesamtdicke D des Glasbausteins von 80 mm. Die hohlzylinderförmigen Vertiefungen 12 haben entsprechende Abmessungen.The connecting projections 10 have the shape of circular cylinders. Their diameter d is approximately 40 mm with a total thickness D of the glass block of 80 mm. The hollow cylindrical depressions 12 have corresponding dimensions.

Bezogen auf die ebene Begrenzungsfläche 5 haben die Dichtvorsprünge 6 eine Höhe H von beispielsweise 0,6 mm. Beim Zusammenfügen der Glasbausteine entsteht dadurch zwischen den ebenen Begrenzungsflächen 5 ein Hohlraum mit einer Höhe von 1,2 mm. Dieser Hohlraum dient für die Einlage von Armierungsbändern 14. Die Armierungsbänder 14 weisen in den durch die Vorsprünge 10 bzw. Vertiefungen 12 vorgegebenen Abständen gestanzte Löcher 15 auf und bestehen aus einem 1 mm dicken Metallband. Je nach den statischen Anforderungen, die an das Wandteil gestellt werden, können die Armierungsbänder 14 aus einem hierfür geeigneten Metall bestehen, z. B. aus Aluminium bei geringen statischen Anforderungen, oder aus Edelstahl bei hohen statischen Anforderungen.Relative to the flat boundary surface 5, the sealing projections 6 have a height H of, for example, 0.6 mm. When the glass blocks are joined together, this creates a cavity with a height of 1.2 mm between the flat boundary surfaces 5. This cavity serves for the insertion of reinforcement tapes 14. The reinforcement tapes 14 have punched holes 15 at the intervals specified by the projections 10 or depressions 12 and consist of a 1 mm thick metal tape. Depending on the static requirements placed on the wall part, the reinforcement tapes 14 can consist of a suitable metal, for. B. made of aluminum for low static requirements, or stainless steel for high static requirements.

Zwischen den Armierungsbändern 14 und den ebenen Begrenzungsflächen 5 besteht unter den genannten Bedingungen ein Spiel von 0,2 mm. Um dieses Mass können sich die Dichtvorsprünge 6 im Extremfall zusammendrücken, wodurch die Abdichtung weiter verbessert wird.Under the conditions mentioned, there is a play of 0.2 mm between the reinforcement bands 14 and the flat boundary surfaces 5. In extreme cases, the sealing projections 6 can compress by this amount, which further improves the sealing.

Die Umrahmung 3 besteht aus einem Integralschaumstoff, d. h. einem Kunststoff mit einer ungeschäumten Deckschicht und einem geschäumten Kern. Besonders geeignet ist z. B. ein harter Polyurethan-Integralschaumstoff mit einer formgeschäumten Rohdichte von 400 bis 700 kgjm3, einem Biege-E-Modul nach DIN 53423 von 950 bis 110 MPa, einer Druckfestigkeit nach DIN 53421 bei 10% Stauchung von 10 bis 18 MPa, einer Shore-D-Härte nach DIN 53505 von 70 bis 85 und einer linearen Wärmedehnzahl nach DIN 53122 von < 100 m/m . K . 106, jeweils bei einer Rohdichte von 600 kg/m3. Bei diesen Integralschaumstoffen kommt den Eigenschaften der kompakten Deckschichten eine entscheidende Rolle zu. Diese Deckschicht hat neben der geschlossenen Oberfläche auch einen deutlich höheren E-Modul als der Integralwerkstoff. Der E-Modul der Deckschicht kann Werte bis 2000 MPa annehmen. Die genannten Bedingungen erfüllt in zufriedenstellender Weise beispielsweise der Integralschaumstoff der Fa. Bayer mit dem Handelsnamen Baydur 6510 F. Dieser Werkstoff hat bei einer Rohdichte von 600 kg/m3 einen Biege-E-Modul von 1050 M Pa, eine Druckfestigkeit von 12 M Pa, eine Shore-D-Härte von 79 und eine lineare Wärmedehnzahl von 90 m/m - K· 106. Den beiden, zu dem Polyurethan reagierenden Polyol- und Isocyanatkomponenten wird beim Mischen ein flüssiges Treibmittelzugesetzt, wodurch das bei der Reaktion der Komponenten entstehende Polyurethan aufschäumt.The frame 3 consists of an integral foam, ie a plastic with an unfoamed cover layer and a foamed core. Z is particularly suitable. B. a rigid integral polyurethane foam with a molded foam density of 400 to 700 kgjm 3 , a flexural modulus according to DIN 53423 from 950 to 110 MPa, a compressive strength according to DIN 53421 at 10% compression of 10 to 18 MPa, a Shore -D hardness according to DIN 53505 from 70 to 85 and a linear thermal expansion coefficient according to DIN 53122 of <100 m / m. K. 10 6 , each with a bulk density of 600 kg / m 3 . With these integral foams, the properties of the compact cover layers play a decisive role. In addition to the closed surface, this cover layer also has a significantly higher modulus of elasticity than the integral material. The modulus of elasticity of the cover layer can assume values up to 2000 MPa. The integral foam from Bayer with the trade name Baydur 6510 F satisfactorily fulfills the stated conditions. With a bulk density of 600 kg / m 3, this material has a flexural modulus of elasticity of 1050 M Pa, a compressive strength of 12 M Pa , a Shore D hardness of 79 and a linear thermal expansion coefficient of 90 m / m - K · 10 6 . A liquid blowing agent is added to the two polyol and isocyanate components which react to form the polyurethane, causing the polyurethane formed during the reaction of the components to foam.

Auf dem Umfang der Umrahmung 3 können die Vorsprünge 10 und die Vertiefungen 12 für die Steckverbindungen grundsätzlich in beliebiger Anordnung angebracht sein. So können z. B. zwei einander gegenüberliegende Seiten mit Vorsprüngen 10, und die beiden anderen, einander gegenüberliegenden Seiten mit Vertiefungen 12 versehen sein. Statt dessen kann man aber auch je zwei aneinander angrenzende Seiten mit Vorsprüngen und Vertiefungen versehen oder, wie beim dargestellten Ausführungsbeispiel, jeweils abwechselnd einen Vorsprung 10 und eine Vertiefung 12 vorsehen.On the circumference of the frame 3, the projections 10 and the depressions 12 for the plug connections can in principle be arranged in any arrangement. So z. B. two opposite sides with projections 10, and the other two opposite sides with recesses 12. Instead, however, two adjacent sides can also be provided with projections and depressions or, as in the exemplary embodiment shown, alternately each have a projection 10 and a depression 12.

Die Fig. 3 bis 5 veranschaulichen, wie ein Wandteil aus solchen beschriebenen Glasbausteinen innerhalb einer Maueröffnung 18 mit Hilfe des erfindungsgemässen Montage- und Wandanschlusssystems aufgebaut wird. Zu diesem Zweck wird zunächst auf den Boden 31 der Maueröffnung 18 ein U-Profilstab 20 mit den Schenkeln aufgestellt und mit Hilfe von Dübeln und Schrauben 23 auf dem Untergrund befestigt. Der U-Profilstab 20 weist in seinem Mittelsteg 21 eine Vertiefung 22 auf, deren Abmessungen so gewählt sind, dass die Vorsprünge 10 der Umrahmung eines Glasbausteins in dieser Vertiefung 22 Platzfinden. Auf diese Weise werden die Glasbausteine auf dem Profilstab 20 in ihrer Lage fixiert.3 to 5 illustrate how a wall part made of such described glass blocks is constructed within a wall opening 18 with the aid of the assembly and wall connection system according to the invention. For this purpose, a U-profile rod 20 with the legs is first placed on the floor 31 of the wall opening 18 and fastened to the substrate with the aid of dowels and screws 23. The U-shaped bar 20 has a recess 22 in its central web 21, the dimensions of which are selected such that the projections 10 of the frame of a glass block 22 are accommodated in this recess. In this way, the glass blocks are fixed in position on the profile bar 20.

Nachdem die unterste Reihe der Glasbausteine 1 auf dem Profilstab 20 angeordnet ist, wird an die beiden äussersten Glasbausteine seitlich jeweils ein Profilabschnitt 24 mit seinem Mittelsteg angesetzt. Einzelheiten hierzu sind insbesondere aus der Fig. 4 ersichtlich. Die Profilabschnitte 24 haben eine Länge L, die genau der Höhe der umrahmten Glasbausteine entspricht. Im Querschnitt sind die Profilabschnitte 24 genauso gestaltet wie der Profilstab 20. Der Mittelsteg der Profilabschnitte 24 weist infolgedessen ebenfalls eine mittlere Vertiefung 26 von U-förmigem Querschnitt auf, in der die Verbindungsvorsprünge 10 der Glasbausteinumrahmung Platz finden. Die beiden Schenkel der Profilabschnitte 24 weisen an den Enden nach innen gerichtete Ansätze 27 auf. Ferner sind an dem Mittelsteg des Profilabschnitts 24 in der Nähe der Schenkel L-förmige Ansätze 28 vorgesehen. Durch diese Ansätze 27 und 28 werden einerseits Kammern 29 von rechteckigem Querschnitt gebildet, die zur Aufnahme von Verbindungsstücken 30 dienen, mit denen die Profilabschnitte 24 untereinander verbunden werden. Die L-förmigen Ansätze 28 haben solche Abmessungen, dass sich ihre äusseren Begrenzungsflächen in derselben Ebene befinden wie die Wandoberfläche der Vertiefung 26.After the bottom row of the glass blocks 1 is arranged on the profile bar 20, a profile section 24 with its central web is attached to the two outermost glass blocks. Details of this can be seen in particular from FIG. 4. The profile sections 24 have a length L which corresponds exactly to the height of the framed glass blocks. In cross section, the profile sections 24 are designed in exactly the same way as the profile bar 20. The central web of the profile sections 24 consequently likewise has a central recess 26 of U-shaped cross section, in which the connecting projections 10 of the glass module frame can be accommodated. The two legs of the profile sections 24 have inwardly directed lugs 27 at the ends. Furthermore, L-shaped projections 28 are provided on the central web of the profile section 24 in the vicinity of the legs. By means of these approaches 27 and 28, chambers 29 of rectangular cross-section are formed on the one hand, which serve to receive connecting pieces 30 with which the profile sections 24 are connected to one another. The L-shaped lugs 28 have dimensions such that their outer boundary surfaces are in the same plane as the wall surface of the recess 26.

Nachdem die Profilsabschnitte 24 aus den Profilstab 20 aufgestellt und gegen die Umrahmung der Glasbausteine angedrückt sind, werden innerhalb der Profilabschnitte 24 Keile 32 mit der Breitseite auf den Profilstab 20 aufgestellt und gegen den Mittelsteg der Profilabschnitte 24 angelegt. Diese Keile 32 berühren die Aussenfläche der Vertiefungen 26 einerseits und die Ansätze 28 andererseits. Die Ansätze 28 übertragen die von dem Keil 32 ausgeübten Anpresskräfte auf die Dichtvorsprünge 6 der Umrahmung, und weiter über die Sichtwand 1' der Glasbausteine auf den auf der anderen Seite der Sichtwand 1' angeordneten Teil der Umrahmung und auf die sich anschliessenden Glasbausteine in dieser Glasbausteinreihe. Die erforderliche Anpresskraft wird erzeugt durch jeweils einen weiteren Keil 33, der mit seiner Schmalseite nach unten zwischen den Keil 32 und das benachbarte Mauerwerk geschoben und dort mit einigen Hammerschlägen eingetrieben wird. Die Standkeile 32 haben ebenso wie die Profilabschnitte 24 die gleiche Länge L, die der Höhe der Glasbausteine entspricht. Die Schubkeile 33 hingegen sind kürzer ausgebildet, so dass im verspannten Zustand ihre obere Begrenzungsfläche unterhalb des Niveaus der oberen Begrenzungsfläche der Standkeile 32 liegt. Die oberen Begrenzungsfläche der Standkeile 32 bildet die Aufsetzfläche, auf die der nächstfolgende Standkeil für die darüberliegende Steinreihe aufgestellt wird.After the profile sections 24 are set up from the profile bar 20 and pressed against the framing of the glass blocks, wedges 32 with the broad side are set up on the profile bar 20 within the profile sections 24 and placed against the central web of the profile sections 24. These wedges 32 touch the outer surface of the depressions 26 on the one hand and the lugs 28 on the other. The lugs 28 transmit the pressing forces exerted by the wedge 32 to the sealing projections 6 of the frame, and further via the viewing wall 1 'of the glass blocks to the part of the frame arranged on the other side of the viewing wall 1' and to the adjoining glass blocks in this row of glass blocks . The required contact pressure is generated by a further wedge 33, which is pushed with its narrow side down between the wedge 32 and the adjacent masonry and is driven there with a few hammer blows. The standing wedges 32, like the profile sections 24, have the same length L, which corresponds to the height of the glass blocks. The push wedges 33, on the other hand, are shorter, so that in the tensioned state their upper boundary surface lies below the level of the upper boundary surface of the standing wedges 32. The upper boundary surface of the standing wedges 32 forms the contact surface on which the next standing wedge for the row of stones above is placed.

Die Keile 32,33 haben einen rechteckigen Querschnitt und entsprechen in ihren Breitenabmessungen etwa den Innenabmessungen der Profilabschnitte 24. Sie bestehen aus einem Werkstoff, der etwa die gleiche Druckfestigkeit aufweist wie das Material der Umrahmung 3 der Glasbausteine. Insbesondere haben sich auch hierfür Polyurethan-I ntegralschaumstoffe bewährt. Ihre Druckfestigkeit kann vorzugsweise etwas niedriger sein als die Druckfestigkeit der Glasbausteinumrahmung. Statt dessen lassen sich auch Keile mit einer höheren Druckfestigkeit verwenden, wenn man zwischen die Keile und die Glasbausteine einen Zwischenkörper zwischenschaltet, der seinerseits eine geringere Druckfestigkeit aufweist und so die gewünschte Sicherheitsfunktion übernimmt. Auf diese Weise wird verhindert, dass beispielsweise bei zu starkem Eintreiben der Keile 33, oder bei übermässig starker Wärmeausdehnung der Glasbausteinwand, die Umrahmung 3 bzw. die Dichtvorsprünge 6 Schaden nehmen, weil in solchen Fällen zunächst die Keile 32, 33 unter den Druckkräften nachgeben. Selbstverständlich ist bei der Auswahl der Werkstoffe für die Keile 32, 33 die spezifische Druckbelastung zu berücksichtigen, die sich aus der Gestaltung des Querschnitts der Profilsabschnitte 24 ergibt.The wedges 32, 33 have a rectangular cross-section and their width dimensions correspond approximately to the internal dimensions of the profile sections 24. They consist of a material which has approximately the same compressive strength as the material of the frame 3 of the glass blocks. In particular, polyurethane integral foams have also proven themselves for this purpose. Their compressive strength can preferably be somewhat lower than the compressive strength of the glass block frame. Instead, wedges with a higher compressive strength can be used if an intermediate body is inserted between the wedges and the glass blocks, which in turn has a lower compressive strength and thus takes over the desired safety function. In this way, it is prevented that, for example, if the wedges 33 are driven in excessively, or if the glass block wall expands excessively, the frame 3 or the sealing projections 6 are damaged, because in such cases the wedges 32, 33 initially give way under the compressive forces. Of course, when selecting the materials for the wedges 32, 33, the specific pressure load that results from the design of the cross section of the profile sections 24 must be taken into account.

Nachdem die unterste Reihe der Glasbausteine auf diese Weise zwischen den Seitenwänden der Maueröffnung fest eingespannt ist, wird die zweite Steinreihe auf der ersten Steinreihe aufgestellt. Sodann werden in die Kammern 29 der untersten Profilabschnitte 24 Verbindungsstücke 30 eingeschoben (s. auch Fig. 9), und auf die untersten Profilabschnitte 24 über die Verbindungsstücke 30 jeweils ein weiterer Profilabschnitt 24 aufgestellt und gegen die anliegende Glasbausteinumrahmung angelegt. Nunmehr wird auf die gleiche Weise wie zuvor durch Anordnung jeweils eines Standkeils 32, der auf den darunter befindlichen Standkeil 32 aufgesetzt wird, und durch Eintreiben jeweils eines Schubkeils 33 die zweite Glasbausteinreihe zusammengepresst. Diese Vorgänge werden wiederholt, bis die oberste Glasbausteinreihe auf diese Art verlegt ist.After the bottom row of glass blocks has been firmly clamped between the side walls of the wall opening in this way, the second row of stones is placed on the first row of stones. Then, connecting pieces 30 are inserted into the chambers 29 of the lowermost profile sections 24 (see also FIG. 9), and a further profile section 24 is placed on the lowermost profile sections 24 via the connecting pieces 30 and placed against the adjacent glass module frame. Now, in the same manner as before, the second row of glass blocks is pressed together by arranging one standing wedge 32, which is placed on the standing wedge 32 underneath, and driving in a pushing wedge 33. These processes are repeated until the top row of glass blocks is laid in this way.

Zum Anschluss der obersten Glasbausteinreihe an die obere Begrenzung der Mauerwerksöffnung wird ein Profilstab 36, der wiederum den gleichen Querschnitt aufweist wie der Profilstab 20 und die Profilabschnitte 24, auf die oberste Glasbausteinreihe aufgepresst. Der Hohlraum zwischen dem Profilstab 36 und dem Mauerwerk 34 wird mit einem Kunstharzschaum 37 ausgeschäumt, und die verbleibenden Fugen werden mit jeweils einem Dichtstrang 38 aus dauerelastischem Kitt abgedichtet. Ebenso werden zum Schluss die senkrechten Fugen zwischen den Profilabschnitten 24 und den senkrechten Wänden 35 der Mauerwerksöffnung mit jeweils einem Dichtstrang 38 aus dauerelastischem Kitt abgedichtet.To connect the uppermost row of glass modules to the upper boundary of the masonry opening, a profile bar 36, which in turn has the same cross section as the profile bar 20 and the profile sections 24, is pressed onto the top row of glass modules. The cavity between the profile rod 36 and the masonry 34 is foamed with a synthetic resin foam 37, and the remaining joints are each sealed with a sealing strand 38 made of permanently elastic cement. Finally, the vertical joints between the profile sections 24 and the vertical walls 35 of the masonry opening are each sealed with a sealing strand 38 made of permanently elastic cement.

Bei der in Fig. 6 dargestellten Ausführungsform für das erfindungsgemässe Verlegesystem wird wiederum zunächst auf dem Boden der Mauerwerksöffnung ein U-Profil als Unterlage für die unterste Steinreihe befestigt. Sodann wird auf den beiden vertikalen Seitenwänden der Mauerwerksöffnung je ein sich über die ganze Höhe der Mauerwerksöffnung erstreckender U-Profilstab 40 mit Hilfe von Klebersträngen 41 in der Weise befestigt, dass das U-Profil zu den Glasbausteinen hin geöffnet ist. Für den Seitenanschluss an die Glasbausteine werden anstelle metallischer U-Profile Profilkörper 42 aus Kunststoff verwendet. Die Profilkörper 42 haben wiederum dieselbe Höhe wie die umrahmten Glasbausteine. Im Querschnitt gesehen weisen sie auf der an der Umrahmung 3 des Glasbausteins anliegenden Seite eine durchgehende Vertiefung 43 auf, deren Breite und Tiefe den Abmessungen der Verbindungsvorsprünge 10 entsprechen. Die der Vertiefung 43 gegenüberliegende Seite des Profilskörpers 42 ist eben ausgebildet. Die Breite C des Profil körpers 42 entspricht der Breite der Umrahmung 3. Der Profilkörper 42 ist vorzugsweise aus dem gleichen Material hergestellt wie die Umrahmung 3.In the embodiment shown in FIG. 6 for the laying system according to the invention, a U-profile is in turn first attached to the bottom of the masonry opening as a base for the bottom row of stones. Then a U-profile bar 40, which extends over the entire height of the masonry opening, is attached to the two vertical side walls of the masonry opening with the aid of adhesive strands 41 in such a way that the U-profile is open towards the glass blocks. For the side connection to the glass blocks, plastic profile bodies 42 are used instead of metal U-profiles. The profile body 42 in turn have the same height as the framed glass blocks. Viewed in cross section, they have a continuous recess 43 on the side abutting the frame 3 of the glass block, the width and depth of which correspond to the dimensions of the connecting projections 10. The side of the profile body 42 opposite the recess 43 is flat. The width C of the profile body 42 corresponds to the width of the frame 3. The profile body 42 is preferably made of the same material as the frame 3rd

Sobald eine Glasbausteinreihe zusammengestellt ist, wird jeweils seitlich auf den äussersten Stein ein Profilkörper 42 aufgeschoben. Die Profilkörper 42 ragen jeweils in das U-Profil 40 hinein. Nun wird zwischen den Mittelsteg des U-Profils 40 und den Profilkörper 42 ein Keil 32 gestellt, und zwischen diesen Keil 32 und den Mittelsteg des U-Profils 40 ein Keil 33 von oben eingetrieben, wodurch die Glasbausteine in dieser Reihezusammengepresst werden. In die Fugen zwischen dem U-Profil 40 und den Profilkörpern 42 werden anschliessend Schaumstoffstreifen 44 eingelegt. Die Abdichtung zwischen dem U-Profil 40 und dem Mauerwerk bzw. den Profilkörpern 42 erfolgt wiederum durch Ausspritzen mit einer dauerplastischen Dichtmasse 38.As soon as a row of glass blocks has been put together, a profile body 42 is pushed laterally onto the outermost stone. The profile body 42 each protrude into the U-profile 40. Now a wedge 32 is placed between the central web of the U-profile 40 and the profile body 42, and a wedge 33 is driven in from above between this wedge 32 and the central web of the U-profile 40, whereby the glass blocks are pressed together in this row. Foam strips 44 are then inserted into the joints between the U-profile 40 and the profile bodies 42. The seal between the U-profile 40 and the masonry or the profile bodies 42 is again made by spraying with a permanently plastic sealing compound 38.

Fig. 7 zeigt ein Ausführungsbeispiel, bei dem ebenso wie bei dem zuletzt beschriebenen Beispiel auf den vertikalen Wänden 35 der Mauerwerksöffnung U-Profilstäbe 40 über Kleberstränge 41 befestigt sind. Zwischen die Schenkel dieser U-Profile 40 werden Profilabschnitte 24 eingeschoben. Diese Profilabschnitte 24, die dieselbe Höhe aufweisen wie die umrahmten Glasbausteine, sind anhand der Fig. 3 bis 5 ausführlich beschrieben worden. Das Innenmass I des U-Profils 40 entspricht dem Aussenmass A der Profilabschnitte 24. Die Profilabschnitte 24 können innerhalb des U-Profils 40 unterschiedlich weit eingeschoben werden,so dass die üblichen Masstoleranzen hierdurch ausgeglichen werden können. Der erforderlicheAnpressdruck in horizontaler Richtung innerhalb einer jeden Glasbausteinreihe wird wie in den voraufgehenden Beispielen durch Einsetzen des Standkeils 32 und Eintreiben des Schubkeils 33 bewirkt. Die verbleibenden Fugen werden durch Ausspritzen mit einer dauerplastischen Dichtmasse 38 abgedichtet.7 shows an exemplary embodiment in which, as in the example described last, U-profile bars 40 are fastened on the vertical walls 35 of the masonry opening by means of adhesive strands 41. Profile sections 24 are inserted between the legs of these U-profiles 40. These profile sections 24, which have the same height as the framed glass blocks, have been described in detail with reference to FIGS. 3 to 5. The internal dimension I of the U-profile 40 corresponds to the external dimension A of the profile sections 24. The profile sections 24 can be inserted to different degrees within the U-profile 40, so that the usual dimensional tolerances can be compensated for. The required contact pressure in the horizontal direction within each row of glass blocks is effected, as in the previous examples, by inserting the standing wedge 32 and driving in the pushing wedge 33. The remaining joints are sealed by spraying with a permanently plastic sealant 38.

Das in Fig. 8 dargestellte Ausführungsbeispiel unterscheidet sich von den bisher beschriebenen Beispielen dadurch, dass Profilabschnitte 46 zum Einsatz kommen, deren Schenkel eine grössere Länge aufweisen als die Schenkel der Profilabschnitte 24. Auf diese Weise wird es möglich, grössere Zwischenräume zwischen den Glasbausteinen und den vertikalen Wänden 35 zu überbrücken. Bei Verwendung der gleichen Keile 32, 33 sind in diesem Fall zusätzliche Distanzkörper 47 erforderlich, die zwischen den Mittelsteg der Profilabschnitte 46 und den Standkeil 32 zwischengeschaltet werden. Auch diese Distanzkörper 47 bestehen bevorzugt aus dem gleichen Material wie die Umrahmung 3, nämlich aus einem Polyurethan-Integralschaum. Die übereinander angeordneten Profilabschnitte 46 sind miteinander durch Verbindungsstücke 48 verbunden.The embodiment shown in FIG. 8 differs from the examples described so far in that profile sections 46 are used, the legs of which have a greater length than the legs of the profile sections 24. In this way it becomes possible to have larger gaps between the glass blocks and the to bridge vertical walls 35. If the same wedges 32, 33 are used, additional spacers 47 are required in this case, which are interposed between the central web of the profile sections 46 and the standing wedge 32. These spacers 47 also preferably consist of the same material as the frame 3, namely of a polyurethane integral foam. The arranged one above the other Neten profile sections 46 are interconnected by connectors 48.

Fig. 9 veranschaulicht in Form einer perspektivischen Darstellung noch einmal den Aufbau der Profilabschnitte 24 und ihre gegenseitige Verbindung mit Hilfe der Verbindungsstücke 30.FIG. 9 once again illustrates in the form of a perspective representation the structure of the profile sections 24 and their mutual connection with the aid of the connecting pieces 30.

Eine weitere Möglichkeit für den unteren und den oberen Wandanschluss eines erfindungsgemäss aufgebauten Wandteils aus Glasbausteinen ist in Fig. 10 dargestellt. In diesem Fall sind zwischen das Bodenprofil 20 und das Mauerwerk 31 zwei Metallprofile 50, 51 und 52 zwischengeschaltet. Diese Metallprofile 50, 51 und 52 haben die Aufgabe, evtl. zwischen die Dichtvorsprünge 6 eingedrungenes Wasser abzuführen. Zu diesem Zweck sind die Profile 50, 51 und 52 im Querschnitt derart winkelig ausgebildet, dass die horizontalen Schenkel durch Keile 53 unterstützt derart geneigt angeordnet sind, dass das evtl. eingedrungene Wasser durch Bohrungen 54 in dem Profil 20 und durch Bohrungen 55 in dem Profil 52 über die Wassernase 56 des Profils 51 abläuft.A further possibility for the lower and the upper wall connection of a wall part constructed according to the invention from glass blocks is shown in FIG. 10. In this case, two metal profiles 50, 51 and 52 are interposed between the floor profile 20 and the masonry 31. These metal profiles 50, 51 and 52 have the task of draining water that may have penetrated between the sealing projections 6. For this purpose, the profiles 50, 51 and 52 are of an angular cross-section such that the horizontal legs are supported inclined by wedges 53 such that the water which may have penetrated through holes 54 in the profile 20 and through holes 55 in the profile 52 runs over the water nose 56 of the profile 51.

Der obere Wandanschluss umfasst in diesem Fall anstelle eines U-Profils zwei L-Profile 58, 59. Das L-Profil 58, wird' auf dem Mauerwerk 34 auf geeignete Weise befestigt. Nachdem die oberste Glasbausteinreihe montiert ist, wird ein Profilstab 20' auf die umrahmten Glasbausteine aufgepresst. Der eine Schenkel des Profilstabs 20' liegt an dem nach unten ragenden Schenkel des L-Profils 58 an. Der Zwischenraum zwischen dem L-Profil 58 und dem U-Profilstab 20' wird sodann mit einem Kunststoffschaum 60 ausgefüllt. Anschliessend wird die verbliebene Öffnung durch Überschieben des L-Profils 59 geschlossen, und die verbleibenden Fugen werden durch Ausspritzen mit einer Dichtmasse 38 abgedichtet.In this case, the upper wall connection comprises two L-profiles 58, 59 instead of a U-profile. The L-profile 58 is attached to the masonry 34 in a suitable manner. After the uppermost row of glass blocks has been installed, a profile bar 20 'is pressed onto the framed glass blocks. One leg of the profile bar 20 'lies against the leg of the L-profile 58 which projects downward. The space between the L-profile 58 and the U-profile rod 20 'is then filled with a plastic foam 60. The remaining opening is then closed by pushing over the L-profile 59, and the remaining joints are sealed by spraying with a sealing compound 38.
