Abstract

1. Double skin wall system with inner and outer profiled sheets, which are connected together by distance pieces and receive an insulating layer therebetween, wherein bars are provided as distance piece serving to transfer the wind forces to the supports of the wall system, which bars are fixed directly to the supports, characterized in that the bars (5) are bent double-T-shaped from sheet metal in a manner known per se, in that only the two flanges (4, 6) are formed by double thickness sheet metal folding and are connected by a single thickness web (5), and in that the inner profiled sheets (1) are fixed directly on to the inner and broader bar flanges (4) to be fixed to the supports (7), while the outer profiled sheets (2) are fixed directly on to the narrower bar flanges (6) lying outside the insulating layer (3).

Description

Die Erfindung bezieht sich auf ein doppelschaliges Wandsystem der im Oberbegriff des Patentanspruchs 1 angegebenen Gattung.The invention relates to a double-walled wall system of the type specified in the preamble of claim 1.

Es gibt zwei bekannte Wandsysteme, die ihre Vor- und Nachteile haben. Bei dem ersten, von dem im vorliegenden Fall ausgegangen wird, sind besondere waagerechte Riegel, meist U-Profile, an der Außenseite der Stützen befestigt. An diesen Riegeln, die in der Regel einen Abstand zueinander von 2,0 bis 4,5 m haben, werden die inneren Profilbleche (z.B. Trapezbleche) mit Schrauben befestigt, die gleichzeitig die einen (inneren) Schenkel von Distanzhaltern aus Z-Profilen halten, welche die Dämmschicht durchdringen und an ihren äußeren Schenkeln die äußeren Profilbleche (ebenfalls z.B. Trapezbleche) aufnehmen. Die äußeren Profilbleche übertragen die Windkräfte über die Z-Profile in die Wandriegel, die ihrerseits die Kräfte in die Stützen ableiten. Diese Wandkonstruktion ist ziemlich aufwendig und führt zu einer übermäßigen Dicke der Wand (Stütze + Innenprofilblech + Dämmschicht (einschließlich Z-Profil) + Außenprofilblech). Da die Z-Profile den gleichen Abstand wie die Riegel haben, ist der K-Wert (Wärmedurchgangswiderstand) nicht schlecht.There are two known wall systems that have their advantages and disadvantages. In the first, which is assumed in the present case, special horizontal bars, usually U-profiles, are attached to the outside of the supports. The inner profile sheets (e.g. trapezoidal sheets) are fastened to these bars, which are usually at a distance of 2.0 to 4.5 m from each other, with screws that hold one (inner) leg of spacers made of Z profiles at the same time, which penetrate the insulation layer and take up the outer profile sheets (also eg trapezoidal sheets) on their outer legs. The outer profile plates transfer the wind forces via the Z profiles into the wall bars, which in turn divert the forces into the supports. This wall construction is quite complex and leads to an excessive thickness of the wall (support + inner profile sheet + insulation layer (including Z-profile) + outer profile sheet). Since the Z-profiles are at the same distance as the transoms, the K-value (thermal resistance) is not bad.

Bei einer zweiten bekannten Ausführungsform, der sogenannten "Kassettenbauweise", entfallen besondere Riegel, da die Windkräfte über Kassettenstege direkt auf die Stützen übertragen werden. Da jedoch aus statischen Gründen die Kassetten keine große Höhenabmessung haben können und dadurch die kassettenstege in der Regel nur einen Abstand zwischen 400-600 mm voneinander haben, tritt eine wesentliche Minderung des K-Wertes bei diesem Wandsystem ein.In a second known embodiment, the so-called "cassette construction", special bolts are omitted, since the wind forces are transmitted directly to the supports via cassette webs. However, since for structural reasons the cassettes cannot have a large height dimension and therefore the cassette bars usually only have a distance of between 400-600 mm from each other, the K-value is significantly reduced with this wall system.

Der Erfindung liegt die Aufgabe zugrunde, ein Wandsystem zu schaffen, das die Vorzüge der beiden geschilderten bekannten Systeme mit relativ einfachen kostensparenden konstruktiven Mitteln in sich vereinigt und eine einfachere Montage ermöglicht.The invention has for its object to provide a wall system which combines the advantages of the two known systems described with relatively simple cost-saving design means and allows for easier assembly.

Diese Aufgabe wird erfindungsgemäß durch die Kennzeichnungsmerkmale des Patentanspruchs 1 gelöst. Zweckmäßige Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the characterizing features of claim 1. Appropriate developments of the invention are the subject of the dependent claims.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Dabei zeigt

  • Fig. 1 einen senkrechten Schnitt durch ein Teilstück des Wandsystems und
  • Fig. 2 eine gegenüber Fig. 1 vergrößerte Darstellung des Querschnittprofils eines Distanzhalters.
In the drawing, an embodiment of the invention is shown. It shows
  • Fig. 1 shows a vertical section through a section of the wall system and
  • Fig. 2 is an enlarged view of FIG. 1 of the cross-sectional profile of a spacer.

Das dargestellte Wandsystem weist innere Profilbleche 1 und äußere Profilbleche 2 auf, zwischen denen sich eine Dämmschicht 3 befindet. Die inneren Profilbleche 1 sind an Flanschen 4 von Distanzhaltern 5 befestigt, während die äußeren Profilbleche 2 an schmäleren Flanschen 6 der Distanzhalter 5 befestigt, z.B. verschraubt, werden. Die Distanzhalter 5 sind ihrerseits an strichpunktiert angedeuteten Stützen 7 befestigt. Die Stege der Distanzhalter 5 durchdringen die Dämmschicht 3 in Abständen zwischen 2,0 und 4,5 m, so daß bei sicherer Übertragung der Windkräfte keine Reduzierung des K-Wertes eintritt.The wall system shown has inner profile sheets 1 and outer profile sheets 2, between which there is an insulation layer 3. The inner profile sheets 1 are attached to flanges 4 of spacers 5, while the outer profile sheets 2 are attached to narrower flanges 6 of the spacers 5, e.g. screwed. The spacers 5 are in turn attached to supports 7 indicated by dash-dotted lines. The webs of the spacers 5 penetrate the insulation layer 3 at intervals between 2.0 and 4.5 m, so that there is no reduction in the K value when the wind forces are transmitted safely.

Wie insbesondere Fig. 2 zeigt, ist jeder Distanzhalter 5 aus Blech gebogen (z.B. aus verzinktem Feinblech 2 mm), wobei die Flansche 4, 6 durch doppelschichtige Blechfalzungen gebildet sind. Die Distanzhalter haben somit ein relativ geringes Gewicht gegenüber den bekannten Riegeln, deren Funktion sie gleichzeitig übernehmen.As shown in FIG. 2 in particular, each spacer 5 is bent from sheet metal (e.g. from galvanized thin sheet 2 mm), the flanges 4, 6 being formed by double-layer sheet metal folds. The spacers thus have a relatively low weight compared to the known bars, whose function they take over at the same time.

Wie die Zeichnungen erkennen lassen, können alle erforderlichen Arbeiten bei der Montage von außen ausgeführt werden.As can be seen from the drawings, all of the work required for assembly can be carried out from the outside.
