Definitions
- the invention relates to a facade wall with a supporting frame made of vertical posts and bars used between them, which together form skeleton fields for receiving a plate element, for example glazing and / or a panel, and are equipped on the weather side with cover profiles, which, like posts and bars, each have a contact fold for the clamped edge of the associated plate element and are connected to the post or transom via a plurality of longitudinally spaced, made of plastic and each having a flat body connecting elements, which have both ends in a longitudinal profile direction Groove of the mullion or transom and the associated cover profile are fixed, the end engaging in the groove of the transom cover profile each of the connecting elements which can be acted upon by a tool inserted between the plate element (4) and the contact fold (3a) of the cover profile (3) has a detachable coupling spring tongues, each equipped with a locking lug, which protrude in the coupling position over the outer contour of the body and engage behind the undercut groove locking on both sides, and wherein a separate plate element
- the connecting elements disclosed here each consist of a relatively narrow plastic body, the length of which is a multiple of its width.
- the end of each connecting element engaging in the groove of the locking cover profile is formed by a pair of spring tongues, the width of which corresponds to that of the connecting element.
- the underside of each connecting element is covered by a water drip plate inserted into this element.
- the end of each connecting element on the room side is hollow, so that the upper and lower walls can be pressed elastically against one another in this end region.
- the cover profiles are to be separated from the connecting elements by a tool which is inserted between the cover profile and the plate element and is placed against an abutment which extends outwards from at least one narrow longitudinal side of the connecting element. The cover profile is then to be torn off by the latching lugs of the spring tongues by lever action.
- the invention is based, to simplify the facade wall described in terms of devitrification the task.
- each spring tongue has a nose-shaped or strip-shaped handle, which has a shorter distance from the end of the connecting element on the room side and protrudes in the coupling position beyond the outer contour of the body.
- the handle is therefore outside the assigned undercut groove of the frame component and is therefore freely accessible to a tool.
- the connecting element is characterized according to the invention by a flat, square or rectangular body which has on its two opposite flat sides each a plurality of spring tongues arranged in a row next to one another at a distance, the two rows of spring tongues lying opposite one another by about one half of the spring tongue spacing are arranged offset from each other, so that each spring tongue is arranged between two opposite spring tongues. Due to the offset arrangement of the spring tongues, the connecting element can be kept very flat, which has a positive effect on the thermal separation.
- the handling protruding on both flat sides of the connecting element can be applied together with a tool, for example a flat iron, so that the associated frame component can be removed in a simple manner without being destroyed.
- the separate plate element carrier is therefore provided, which can preferably be screwed into the respective grooves of the post receiving one end of the connecting elements and the two bars arranged to the left and right thereof. It is advantageous if the screw connection can be tightened from the weather side of the facade. For reasons of strength, it is expedient if the plate element carrier is supported with a leg on a lower bearing surface of the bolt.
- the connecting element according to the invention can be made very narrow, there is only a small distance between the plate elements arranged next to one another. Normally, the plate element carrier would then be too narrow to be able to bear it on bending. According to the invention, it was therefore designed so that the bending moment is converted into a pair of forces, the tension being taken up by the screws and being forwarded into the post, while the pressure is passed over the lower bearing surface into the transom and from there into the post . This results in a particularly secure support for the plate element, in particular for double glazing.
- the plate element carrier is no longer continuously integrated on the profiles, but only used locally, so that material savings result not only in the horizontal but also in the vertical profiles. Since the plate element carrier is no longer bound to the extrusion profile in terms of production technology, it is arranged according to the invention at the cross point between the mullion and the transom. The dead weight of the panel element is thus introduced directly into the vertical post.
- transoms run into the posts and are connected to the post in a vapor-tight manner via a shock sleeve arranged here. Sealing compounds are therefore not required. This applies above all to the cross point, where the use of molded parts made of elastic plastic means that wet sealing can be omitted.
- the impact sleeve according to the invention fulfills several tasks: it forms in the area where the bolt enters the post with its U-profile running backwards in Extension of the actual seal for the plate element, the steam seal and at the same time the aesthetic covering of the mullion-transom transition.
- the gap formed at the mullion-transom joint varies, for tolerance reasons and for reasons of thermal expansion.
- massive butt collars with a width of 5 to 8 mm are usually required. Since, according to the invention, the bolt runs in the post, there is no butt joint. The movement and tolerance compensation takes place in the mullion-transom transition in the rebate of the mullion, and the covering of the transition is solved with a narrow face width of no more than 1.5 mm.
- the facade wall shown in Figures 1-9 has a supporting structure which consists of vertical posts 1 and between them inserted and connected at right angles to bars 23, which together form framework fields for receiving a plate element 4, e.g. form a glazing and / or a panel and are equipped with cover profiles 3 and 24 on the weather side.
- Posts 1, transoms 23 and cover profiles 3, 24 each have a contact fold 1a, 23a, 3a and 24a for the clamped edge of the associated plate element 4.
- Cover profiles 3, 24 are connected to post 1 or transoms 23 via a plastic connecting part , with its two ends in each case in a longitudinal profile groove 5, 6; 25, 26 of the post 1 or bolt 23 and the associated cover profile is fixed.
- FIG. 8 shows, on an enlarged scale, a horizontal section through the post 1, which is preferably formed by an aluminum profile, and which is connected to the cover profile 3 via a connecting element 2, which forms the plastic connecting part and takes over the static connection function, and which likewise preferably consists of an aluminum profile.
- a connecting element 2 which forms the plastic connecting part and takes over the static connection function, and which likewise preferably consists of an aluminum profile.
- Posts 1 and cover profile 3 each have the mutually facing, undercut on both sides, extending in the longitudinal direction of the profile groove 5 and 6 for the positive reception of one end of the connecting element 2.
- the connecting element 2 shown in more detail in FIGS. 21-27 is made of plastic and has a flat body 7 which is at least approximately square according to FIG. 21 and which is equipped at its lower end in the figures with spring tongues 9 forming a releasable coupling.
- These spring tongues 9 are on the two opposite flat sides 8 of the body 7 in each a row arranged next to each other at a distance, the two rows of spring tongues lying opposite one another being offset from one another by about half the distance between spring tongues, so that each spring tongue is arranged between two spring tongues lying opposite one another.
- Each spring tongue 9 can be pivoted about its spring tongue foot 10 lying at the outermost end of the body 7 into an inner cavity 11 of the body 7 into a decoupling position, specifically against the action of a counter spring 12 projecting into this cavity 11.
- Each spring tongue 9 is equipped with a locking lug 13 which, in the coupling position of the spring tongue 9, projects beyond the outer contour of the body 7 and engages behind the associated undercut groove 6 of the cover profile 3 in a locking manner (see FIG. 8).
- each spring tongue 9 is pressed against the action of the counter spring 12 acting on it into said cavity 11 until the counter spring 12 engages behind the free end of the spring tongue 9 in a locking manner.
- a recess 14 is provided at the free end of each spring tongue 9, in which the counter spring 12 can engage in a locking manner (FIG. 27).
- the locking lug 13 is at least largely within the outer contour of the body 7, so that the connecting element 2 can be pulled out of the groove 6 of the cover profile 3 with its one end.
- each spring tongue 9 has a nose-shaped or strip-shaped handle 15, which has a shorter distance from the other end of the connecting element 2 in comparison to the latching nose 13 and which is shown in FIG Coupling position over the outer contour of the body 7 protrudes.
- the upper end of the connecting element 2 is designed as a resilient fork, the two spring tines 16 of which can be pressed resiliently against one another at their free end each have a detent 17 projecting in a spread coupling position over the outer contour of the body 7, which in the coupling position has the associated one Grip undercut groove 5 of post 1 on both sides.
- the connecting element 2 with its fork tines 16 is inserted into the groove 5, the bevels provided on the latching lugs 17 leading to a compression of the fork tines 16 when the connecting element 2 is inserted, which automatically reach the locking position when the groove bottom is reached due to their inherent elasticity rebound.
- bolts 18 are inserted between the fork tines 16.
- Each bolt 18 can have a longitudinal toothing, be fixed in its locking position by local brackets and be formed in one piece with the connecting element 2.
- 2 hollow chambers 21 are arranged in the body 7 of the connecting element.
- the massive separating webs between the individual spring tongues 9 are identified by the reference number 22.
- the connecting element 2 combines both a thermal separation and a static connection of the metal components 1, 3 without generating new cold bridges. Nevertheless, it is an easily detachable connection that can be dismantled e.g. of the cover profile 3 without destruction.
- the spring tongues 9 engage behind the undercut groove 6 on both sides, i.e. for decoupling the spring tongues 9 provided on both flat sides 8 of the connecting element 2 must be pressed into the body 7, this body can be made very flat due to the offset arrangement of the spring tongues 9 and has in a special embodiment has a thickness of only 11.5 mm. This enables very favorable values for the thermal separation of the frame profiles.

- the plate element carrier 27 is approximately Z-shaped in cross section and engages with stiffening ribs 30 in the grooves 25 of the bolts 23.
- FIGS. 10-13 show that the bars 23 run into the post 1 and are connected to the post 1 in a vapor-tight manner by means of a shock sleeve 31 arranged here.
Abstract
Description
Die Erfindung betrifft eine Fassadenwand mit einem Traggerippe aus lotrechten Pfosten und zwischen diesen eingesetzten Riegeln, die gemeinsam Gerippefelder zur Aufnahme je eines Plattenelementes, z.B. einer Verglasung und/oder eines Paneels, bilden und wetterseitig mit Abdeckprofilen bestückt sind, die ebenso wie Pfosten und Riegel je einen Anlagefalz für den klemmend gehaltenen Rand des zugeordneten Plattenelementes aufweisen und mit dem Pfosten bzw. Riegel über mehrere, mit Längsabstand voneinander angeordnete, aus Kunststoff hergestellte und jeweils einen flachen Körper aufweisende Verbindungselemente verbunden sind, die mit ihren beiden Enden in je einer in Profillängsrichtung verlaufenden Nut des Pfostens bzw. Riegels und des zugordneten Abdeckprofils festgelegt sind, wobei das in die Nut des Riegel-Abdeckprofils eingreifende Ende jedes von einem zwischen Plattenelement (4) und Anlagefalz (3a) des Abdeckprofils (3) eingeschobenen Werkzeug beaufschlagbaren Verbindungselementes eine lösbare Kupplung bildende Federzungen aufweist, die mit je einer Rastnase bestückt sind, die in Kupplungsstellung über die Außenkontur des Körpers vorstehen und die hinterschnitten ausgebildete Nut beidseitig verriegelnd hintergreifen, und wobei im Kreuzpunkt zwischen Pfosten und Riegel zwischen den Verbindungselementen ein separater Plattenelementträger befestigt ist, der jeweils zwei benachbarten Riegeln zugeordnet ist und je eine Auflagefläche für deren Plattenelemente (4) aufweist.The invention relates to a facade wall with a supporting frame made of vertical posts and bars used between them, which together form skeleton fields for receiving a plate element, for example glazing and / or a panel, and are equipped on the weather side with cover profiles, which, like posts and bars, each have a contact fold for the clamped edge of the associated plate element and are connected to the post or transom via a plurality of longitudinally spaced, made of plastic and each having a flat body connecting elements, which have both ends in a longitudinal profile direction Groove of the mullion or transom and the associated cover profile are fixed, the end engaging in the groove of the transom cover profile each of the connecting elements which can be acted upon by a tool inserted between the plate element (4) and the contact fold (3a) of the cover profile (3) has a detachable coupling spring tongues, each equipped with a locking lug, which protrude in the coupling position over the outer contour of the body and engage behind the undercut groove locking on both sides, and wherein a separate plate element carrier is fastened at the cross point between the mullion and transom between the connecting elements, of the two neighboring ones Bolts is assigned and each has a support surface for its plate elements (4).
Eine derartige Fassadenwand läßt sich der US-A-4 428 171 entnehmen. Die hier offenbarten Verbindungselemente bestehen jeweils aus einem verhältnismäßig schmalen Kunststoffkörper, dessen Länge ein Vielfaches seiner Breite beträgt. Das in die Nut des Riegel-Abdeckprofils eingreifende Ende jedes Verbindungselementes wird durch ein Federzungenpaar gebildet, dessen Breite der des Verbindungselementes entspricht. Die Unterseite jedes Verbindungselementes ist durch ein in dieses Element eingestecktes Wassertropfblech abgedeckt. Das raumseitige Ende jedes Verbindungselementes ist hohl ausgebildet, so daß sich in diesem Endbereich die obere und untere Wandung elastisch gegeneinander drücken lassen. Die Trennung der Abdeckprofile von den Verbindungselementen soll durch ein Werkzeug erfolgen, das zwischen Abdeckprofil und Plattenelement eingeführt und an ein Widerlager angelegt wird, das sich von zumindest einer schmalen Längsseite des Verbindungselementes nach außen erstreckt. Durch Hebelwirkung soll das Abdeckprofil dann von den Rastnasen der Federzungen abgerissen werden.Such a facade wall can be found in US-A-4 428 171. The connecting elements disclosed here each consist of a relatively narrow plastic body, the length of which is a multiple of its width. The end of each connecting element engaging in the groove of the locking cover profile is formed by a pair of spring tongues, the width of which corresponds to that of the connecting element. The underside of each connecting element is covered by a water drip plate inserted into this element. The end of each connecting element on the room side is hollow, so that the upper and lower walls can be pressed elastically against one another in this end region. The cover profiles are to be separated from the connecting elements by a tool which is inserted between the cover profile and the plate element and is placed against an abutment which extends outwards from at least one narrow longitudinal side of the connecting element. The cover profile is then to be torn off by the latching lugs of the spring tongues by lever action.
Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Fassadenwand hinsichtlich ihrer Entglasungsmöglichkeiten zu vereinfachen.The invention is based, to simplify the facade wall described in terms of devitrification the task.
In Verbindung mit den eingangs beschriebenen Merkmalen wird diese Aufgabe gemäß der Erfindung durch folgende zusätzliche Merkmale gelöst:
- a) jede Federzunge ist gegen die Wirkung einer in einen inneren Hohlraum des Körpers ragende Gegenfeder in diesen Hohlraum hineinverschwenkbar in eine Entkupplungsstellung, in der die Rastnase zumindest weitgehend innerhalb der Außenkontur des Körpers liegt;
- b) in einer Entkupplungsstellung wird die Federzunge durch die das freie Ende der Federzunge hintergreifende Gegenfeder automatisch arretiert;
- c) das freie Ende beider Federzungen ist so angeordnet, daß es von dem zwischen Plattenelement und Anlagefalz des Abdeckprofils eingeschobenen Werkzeug beaufschlagbar ist.
- a) each spring tongue can be pivoted against the action of a counter spring projecting into an inner cavity of the body into this cavity into a decoupling position in which the latching lug lies at least largely within the outer contour of the body;
- b) in a decoupling position, the spring tongue is automatically locked by the counter spring engaging behind the free end of the spring tongue;
- c) the free end of both spring tongues is arranged so that it can be acted upon by the tool inserted between the plate element and the contact fold of the cover profile.
Um das Verschwenken der Federzungen in ihre Entkupplungsstellung zu erleichtern und z.B. mit einem Werkzeug durchführen zu können, ist es zweckmäßig, wenn jede Federzunge eine nasen- bzw. leistenförmige Handhabe aufweist, die im Vergleich zur Rastnase einen kürzeren Abstand vom raumseitigen Ende des Verbindungselementes aufweist und in Kupplungsstellung über die Außenkontur des Körpers vorsteht. Die Handhabe liegt also außerhalb der zugeordneten hinterschnittenen Nut des Rahmenbauteils und ist daher einem Werkzeug frei zugänglich.To facilitate the pivoting of the spring tongues into their uncoupling position and e.g. To be able to carry out with a tool, it is expedient if each spring tongue has a nose-shaped or strip-shaped handle, which has a shorter distance from the end of the connecting element on the room side and protrudes in the coupling position beyond the outer contour of the body. The handle is therefore outside the assigned undercut groove of the frame component and is therefore freely accessible to a tool.
Zur Optimierung der thermischen Trennung ist das Verbindungselement erfindungsgemäß gekennzeichnet durch einen flachen, quadratisch oder rechteckig ausgebildeten Körper, der auf seinen beiden sich gegenüberliegenden Flachseiten jeweils mehrere, in je einer Reihe mit Abstand nebeneinander angeordnete Federzungen aufweist, wobei die beiden sich gegenüberliegenden Federzungenreihen um etwa einen halben Federzungenabstand gegeneinander versetzt angeordnet sind, so daß jede Federzunge zwischen zwei gegenüberliegenden Federzungen angeordnet ist. Durch die versetzte Anordnung der Federzungen kann das Verbindungselement sehr flach gehalten werden, was sich hinsichtlich der thermischen Trennung positiv auswirkt. Die auf beiden Flachseiten des Verbindungselementes herausragenden Handhabungen lassen sich mit einem Werkzeug, z.B. einem Flacheisen, gemeinsam beaufschlagen, so daß sich das zugeordnete Rahmenbauteil in einfacher Weise ohne Zerstörung abnehmen läßt.To optimize the thermal separation, the connecting element is characterized according to the invention by a flat, square or rectangular body which has on its two opposite flat sides each a plurality of spring tongues arranged in a row next to one another at a distance, the two rows of spring tongues lying opposite one another by about one half of the spring tongue spacing are arranged offset from each other, so that each spring tongue is arranged between two opposite spring tongues. Due to the offset arrangement of the spring tongues, the connecting element can be kept very flat, which has a positive effect on the thermal separation. The handling protruding on both flat sides of the connecting element can be applied together with a tool, for example a flat iron, so that the associated frame component can be removed in a simple manner without being destroyed.
Durch die erfindungsgemäße Ausbildung des Kunststoffverbindungsteils fehlt unter dem plattenförmigen Element eine geeignete Trägerfläche. Üblicherweise greift in diesen Raum noch ein inneres Kämpferprofil mit seinen Isolierstegen ein. Erfindungsgemäß ist deshalb der separate Plattenelementträger vorgesehen, der vorzugsweise in den jeweils das eine Ende der Verbindungselemente aufnehmenden Nuten des Pfostens sowie der beiden links und rechts hiervon angeordneten Riegel verschraubt sein kann. Dabei ist es vorteilhaft, wenn die Verschraubung von der Wetterseite der Fassade anziehbar ist. Aus Festigkeitsgründen ist es zweckmäßig, wenn sich der Plattenelementträger mit einem Schenkel auf einer unteren Auflagerfläche des Riegels abstützt.Due to the inventive design of the plastic connecting part, a suitable carrier surface is missing under the plate-shaped element. Usually, an internal fighter profile with its insulating bars also intervenes in this room. According to the invention, the separate plate element carrier is therefore provided, which can preferably be screwed into the respective grooves of the post receiving one end of the connecting elements and the two bars arranged to the left and right thereof. It is advantageous if the screw connection can be tightened from the weather side of the facade. For reasons of strength, it is expedient if the plate element carrier is supported with a leg on a lower bearing surface of the bolt.
Da das erfindungsgemäße Verbindungselement sehr schmal ausgeführt werden kann, ergibt sich zwischen den jeweils nebeneinander angeordneten Plattenelementen nur ein geringer Abstand. Normalerweise wäre dann der Plattenelementträger zu schmal, um ihn auf Biegung belasten zu können. Erfindungsgemäß wurde er daher so ausgebildet, daß das Biegungsmoment in ein Rräftepaar umgewandelt wird, wobei der Zug von den Schrauben aufgenommen und in den Pfosten weitergeleitet werden kann, während der Druck über die untere Auflagerfläche in den Riegel und von dort weiter in den Pfosten geleitet wird. Es ergibt sich somit ein besonders sicheres Auflager für das Plattenelement, insbesondere für eine Isolierverglasung.Since the connecting element according to the invention can be made very narrow, there is only a small distance between the plate elements arranged next to one another. Normally, the plate element carrier would then be too narrow to be able to bear it on bending. According to the invention, it was therefore designed so that the bending moment is converted into a pair of forces, the tension being taken up by the screws and being forwarded into the post, while the pressure is passed over the lower bearing surface into the transom and from there into the post . This results in a particularly secure support for the plate element, in particular for double glazing.
Der Plattenelementträger ist nicht mehr durchlaufend an den Profilen integriert, sondern nur örtlich eingesetzt, so daß sich nicht nur in den horizontalen sondern auch in den senkrechten Profilen eine Materialersparnis ergibt. Da der plattenelementträger herstellungstechnisch nicht mehr an das Extrusionsprofil gebunden ist, wird er erfindungsgemäß im Kreuzpunkt zwischen Pfosten und Riegel angeordnet. Das Eigengewicht des Plattenelementes wird dadurch direkt in den lotrechten Pfosten eingeleitet.The plate element carrier is no longer continuously integrated on the profiles, but only used locally, so that material savings result not only in the horizontal but also in the vertical profiles. Since the plate element carrier is no longer bound to the extrusion profile in terms of production technology, it is arranged according to the invention at the cross point between the mullion and the transom. The dead weight of the panel element is thus introduced directly into the vertical post.
Es ist ferner vorteilhaft, wenn die Riegel in den Pfosten laufen und über je eine hier angeordnete Stoßmanschette dampfdicht am Pfosten angeschlossen sind. Versiegelungsmassen fallen somit nicht an. Dies gilt vor allem auch für den Kreuzpunkt, bei dem durch Einsatz von Formteilen aus elastischem Kunststoff eine Naßversiegelung entfallen kann.It is also advantageous if the transoms run into the posts and are connected to the post in a vapor-tight manner via a shock sleeve arranged here. Sealing compounds are therefore not required. This applies above all to the cross point, where the use of molded parts made of elastic plastic means that wet sealing can be omitted.
Die erfindungsgemäße Stoßmanschette erfüllt mehrere Aufgaben: sie bildet in dem Bereich, wo der Riegel in den Pfosten einläuft, mit ihrem nach hinten laufenden U-Profil in Verlängerung der eigentlichen Dichtung für das Plattenelement die Dampfdichtung und gleichzeitig die ästhetische Abdeckung des Pfosten-Riegel-Übergangs. Üblicherweise variiert der am Pfosten-Riegel-Stoß gebildete Spalt und zwar aus Toleranzgründen sowie aus Gründen der Wärmedehnung. Zur Überbrückung dieser Spaltenbreiten sind üblicherweise massive Stoßmanschetten erforderlich, die mit einer Breite von 5 bis 8 mm in der Ansicht liegen. Da erfindungsgemäß der Riegel in den Pfosten läuft, entsteht keine Stoßfuge. Der Bewegungs- und Toleranzausgleich erfolgt im Pfosten-Riegel-Übergang im Falz des Pfostens, und die Abdeckung des Übergangs ist mit einer schmalen Ansichtsbreite von nicht mehr als 1,5 mm gelöst.The impact sleeve according to the invention fulfills several tasks: it forms in the area where the bolt enters the post with its U-profile running backwards in Extension of the actual seal for the plate element, the steam seal and at the same time the aesthetic covering of the mullion-transom transition. Usually, the gap formed at the mullion-transom joint varies, for tolerance reasons and for reasons of thermal expansion. To bridge these column widths, massive butt collars with a width of 5 to 8 mm are usually required. Since, according to the invention, the bolt runs in the post, there is no butt joint. The movement and tolerance compensation takes place in the mullion-transom transition in the rebate of the mullion, and the covering of the transition is solved with a narrow face width of no more than 1.5 mm.
Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche und werden in Verbindung mit weiteren Vorteilen der Erfindung anhand eines Ausführungsbeispieles näher erläutert.Further features of the invention are the subject of the dependent claims and are explained in connection with further advantages of the invention using an exemplary embodiment.

Die in den Figuren 1 - 9 dargestellte Fassadenwand weist ein Traggerippe auf, das aus lotrechten Pfosten 1 und zwischen diesen eingesetzten und mit diesen rechtwinklig verbundenen Riegeln 23 besteht, die gemeinsam Gerippefelder zur Aufnahme je eines Plattenelementes 4, z.B. einer Verglasung und/oder eines Paneels bilden und wetterseitig mit Abdeckprofilen 3 bzw. 24 bestückt sind. Pfosten 1, Riegel 23 sowie Abdeckprofile 3, 24 weisen jeweils einen Anlagefalz 1a, 23a, 3a und 24a auf für den klemmend gehaltenen Rand des zugeordneten Plattenelementes 4. Die Abdeckprofile 3, 24 sind mit dem Pfosten 1 bzw. Riegel 23 über ein Kunststoffverbindungsteil verbunden, das mit seinen beiden Enden in je einer in Profillängsrichtung verlaufenden Nut 5, 6; 25, 26 des Pfostens 1 bzw. Riegels 23 und des zugeordneten Abdeckprofils festgelegt ist.The facade wall shown in Figures 1-9 has a supporting structure which consists of
Figur 8 zeigt in vergrößertem Maßstab einen Horizontalschnitt durch den vorzugsweise durch ein Aluminiumprofil gebildeten Pfosten 1, der über ein das genannte Kunststoffverbindungsteil bildendes, die statische Verbindungsfunktion übernehmendes Verbindungselement 2 mit dem Abdeckprofil 3 verbunden ist, das ebenfalls vorzugsweise aus einem Aluminiumprofil besteht. Zwischen Pfosten 1 und Abdeckprofil 3 sind als Plattenelemente 4 zwei Isolierverglasungen eingespannt. Pfosten 1 und Abdeckprofil 3 weisen je die einander zugewandte, beidseitig hinterschnittene, in Profillängsrichtung verlaufende Nut 5 bzw. 6 auf zur formschlüssigen Aufnahme je eines Endes des Verbindungselementes 2.FIG. 8 shows, on an enlarged scale, a horizontal section through the
Das in den Figuren 21 - 27 näher dargestellte Verbindungselement 2 besteht aus Kunststoff und weist einen flachen, gemäß Figur 21 zumindest angenähert quadratisch ausgebildeten Körper 7 auf, der an seinem in den Figuren jeweils untenliegenden Ende mit eine lösbare Kupplung bildenden Federzungen 9 bestückt ist. Diese Federzungen 9 sind auf den beiden sich gegenüberliegenden Flachseiten 8 des Körpers 7 in jeweils einer Reihe mit Abstand nebeneinander angeordnet, wobei die beiden sich gegenüberliegenden Federzungen-Reihen um etwa einen halben Federzungen-Abstand gegeneinander versetzt angeordnet sind, so daß jede Federzunge zwischen zwei gegenüberliegenden Federzungen angeordnet ist.The connecting
Jede Federzunge 9 ist um ihren am äußersten einen Ende des Körpers 7 liegenden Federzungen-Fuß 10 in einen inneren Hohlraum 11 des Körpers 7 hinein in eine Entkupplungsstellung verschwenkbar und zwar gegen die Wirkung einer in diesen Hohlraum 11 ragenden Gegenfeder 12.Each
Jede Federzunge 9 ist mit einer Rastnase 13 bestückt, die in Kupplungsstellung der Federzunge 9 über die Außenkontur des Körpers 7 vorsteht und die zugeordnete hinterschnittene Nut 6 des Abdeckprofils 3 verriegelnd hintergreift (siehe Figur 8). Zur Entkupplung wird jede Federzunge 9 gegen die Wirkung der sie beaufschlagenden Gegenfeder 12 in den genannten Hohlraum 11 soweit eingedrückt, bis die Gegenfeder 12 das freie Ende der Federzunge 9 verriegelnd hintergreift. Zur eindeutigen Definition dieser Entkupplungsstellung ist am freien Ende jeder Federzunge 9 eine Ausnehmung 14 vorgesehen, in die die Gegenfeder 12 verriegelnd eingreifen kann (Figur 27). In dieser Entkupplungsstellung liegt dann die Rastnase 13 zumindest weitgehend innerhalb der Außenkontur des Körpers 7, so daß das Verbindungselement 2 mit seinem einen Ende aus der Nut 6 des Abdeckprofils 3 herausgezogen werden kann.Each
Um das Eindrücken der Federzungen 9 in ihre Entriegelungsstellung zu vereinfachen, weist jede Federzunge 9 eine nasen- bzw. leistenförmige Handhabe 15 auf, die im Vergleich zur Rastnase 13 einen kürzeren Abstand von dem anderen Ende des Verbindungselementes 2 aufweist und in der in Figur 8 dargestellten Kupplungsstellung über die Außenkontur des Körpers 7 vorsteht. Dadurch ist es möglich, ohne optische Kontrolle und aufwendige Manipulation beispielsweise mit einer Flachzange die sich gegenüberliegenden Federzungen 9 gleichzeitig in ihre Entriegelungsstellung in den Hohlraum 11 des Verbindungselementes 2 hineinzudrücken, wo dann eine automatische Arretierung aller Federzungen 9 durch die zugeordneten Gegenfedern 12 erfolgt.In order to simplify the pushing-in of the
Das andere, in den Figuren jeweils obere Ende des Verbindungselementes 2 ist als federnde Gabel ausgebildet, deren beiden federelastisch gegeneinander drückbaren Gabelzinken 16 an ihrem freien Ende je eine in gespreizter Kupplungsstellung über die Außenkontur des Körpers 7 vorstehende Rastnase 17 aufweisen, die in Kupplungsstellung die zugeordnete hinterschnittene Nut 5 des Pfostens 1 beidseitig verriegelnd hintergreifen. Zur Herstellung der Verbindung wird das Verbindungselement 2 mit seinen Gabelzinken 16 in die Nut 5 eingeschoben, wobei die an den Rastnasen 17 vorgesehenen Anlaufschrägen beim Einschieben des Verbindungselementes 2 zu einem Zusammendrücken der Gabelzinken 16 führen, die bei Erreichen des Nutgrundes aufgrund ihrer Eigenelastizität selbttätig in Verriegelungsstellung ausfedern. Zur Arretierung dieser Kupplungsstellung werden Bolzen 18 zwischen die Gabelzinken 16 eingeschoben. Jeder Bolzen 18 kann eine Längsverzahnung aufweisen, durch örtliche Halterungen in seiner Arretierungsstellung fixiert werden und einteilig mit dem Verbindungselement 2 ausgebildet sein.The other, in the figures, the upper end of the connecting
Die Verriegelung des mit den Federzungen 9 bestückten Endes des Verbindungselementes 2 mit der Nut 6 des Abdeckprofils 3 erfolgt ebenfalls durch bloßes Einschieben des Verbindungselementes 2, wodurch die mit Auflaufschrägen versehenen Federzungen 9 nach innen gedrückt werden, um nach Erreichen des Nutgrundes wieder ausfedern zu können. Dieses Eindrücken der Federzungen 9 erfolgt zwar gegen die Wirkung der Gegenfedern 12, jedoch nur so weit in den Hohlraum 11 hinein, daß die Gegenfedern 12 den freien Rand der Federzunge 9 noch nicht verriegelnd hintergreifen können.The locking of the end of the connecting
Zur Querschnittsverringerung sind in dem Körper 7 des Verbindungselementes 2 Hohlkammern 21 angeordnet. In Figur 21 sind die massiven Trennstege zwischen den einzelnen Federzungen 9 mit dem Bezugszeichen 22 gekennzeichnet.To reduce the cross-section, 2
Das Verbindungselement 2 vereinigt in sich sowohl eine thermische Trennung als auch eine statische Verbindung der aus Metall bestehenden Bauteile 1, 3, ohne hierbei neue Kältebrücken zu erzeugen. Dennoch handelt es sich um eine leicht lösbare Verbindung, die die Demontage z.B. des Abdeckprofils 3 ohne Zerstörung ermöglicht. Obwohl die Federzungen 9 die hinterschnittene Nut 6 beidseitig hintergreifen, also zur Entkupplung die auf beiden Flachseiten 8 des Verbindungselementes 2 vorgesehenen Federzungen 9 in den Körper 7 eingedrückt werden müssen, kann dieser Körper aufgrund der versetzten Anordnung der Federzungen 9 sehr flach ausgebildet werden und weist in einem speziellen Ausführungsbeispiel eine Dicke von nur 11,5 mm auf. Dies ermöglicht sehr günstige Werte für die thermische Trennung der Rahmenprofile.The connecting
Da die Handhabe 15 jeder Federzunge 9 außerhalb der Nut 6 liegt, sind die Handhaben 15 einem Werkzeug ohne weiteres zugänglich.Since the
Gemäß der Figuren 1 und 3 ist im Kreuzpunkt zwischen Pfosten 1 und Riegel 23 zwischen den Verbindungselementen 2 ein separater Plattenelementträger 27 befestigt, der jeweils zwei benachbarten Riegeln 23 zugeordnet ist und je eine Auflagerfläche 27a, 27b für deren Plattenelement 4 aufweist. Figur 9 zeigt in einem lotrechten Schnitt die Anordnung dieses Plattenelementträgers 27, dessen Ausbildung im Detail den Figuren 14 bis 20 zu entnehmen ist. Demnach stützt sich der Plattenelementträger 27 mit einem Schenkel 28 auf einer unteren Auflagerfläche 29 des Riegels 23 ab. Der Plattenelementträger 27 ist im Querschnitt angenähert Z-förmig ausgebildet und greift mit Versteifungsrippen 30 in die Nuten 25 der Riegel 23 ein.According to FIGS. 1 and 3, a separate
Die Figuren 10 - 13 lassen erkennen, daß die Riegel 23 in den Pfosten 1 laufen und über eine hier angeordnete Stoßmanschette 31 dampfdicht am Pfosten 1 angeschlossen sind.FIGS. 10-13 show that the
