Panel comprises hard foamed core with an adhesive surface coating of closed, non-shrinking hydrophobic, vapour-permeable plastic with non-rusting steel reinforcing mesh. A second reinforcing layer, with a broader outer covering, lap the joints between panels.
Description
Aus thermoisolierenden Verbundhartschaumplatten hergestellte Wandverkleidung
Solche Wandverkleidungen sind allgemein bekannt.
Bei den verschiedenen Ausführungsarten treten jedoch immer wieder Mängel auf, wie ungenügender Schutz der Beschichtungen und Hartschaumplatten gegen mechanische und chemische Einwirkungen, Volumen- und Formveränderungen der Verkleidung, die zu Rissbildungen, Feuchtigkeitseinbrüchen und Kältebrücken finden, ungenügende Haftfestigkeit der Verkleidung mit der Gebäudewand und der Beschichtungen untereinander.
Die Erfindung, welche diese Nachteile behebt, ist dadurch gekennzeichnet, dass die Aussenflächen der Hartschaumplatten vollflächig mit einer schrumpffreien und hydrophoben, dampfdurchlässigen Kunstharzkleberschicht und diese mit einer Armierungsschicht in Form eines nichtrostenden und schiebefesten Stahlgitters verklebt sind, wobei die Stösse der Verbundhartschaumplatten mit einer zweiten Armierungsschicht überdeckt sind und die Wandverkleidung mit einem teils auf der Kunstharzkleberschicht, teils auf der Armierungsschicht haftenden Deckschicht versehen ist.
In der Zeichnung ist ein Beispiel des Erfindungsgedankens dargestellt. Die Figur zeigt einen Ausschnitt der Wandverkleidung im Schnitt.
Auf einer Gebäudewand 1 werden grossflächige Verbundhartschaumplatten, die aus einer Hartschaumplatte 2, einer Kunstharzkleberschicht 3 und einer Armierungsschicht 4 bestehen, mit Nägeln oder Schrauben 5 festgedübelt. Die Plattenstösse 6 sind dicht geschlossen 7. Die Plattenstösse 6 sind mit einer zweiten Armierungsschicht 8 überdeckt. Die derart plan, fluchtgleich und dicht erstellte Wandverkleidung ist mit einem Deckputz 9 versehen, der teils auf der Kunstharzschicht und teils auf der Armierungsschicht haftet.
Die Kunstharzkleberschicht 3 härtet schrumpf- und rissfrei aus und ist dampfdurchlässig, so dass Form und Volumen sowie die Atmungsfähigkeit der Verbundplatte erhalten bleiben. Die Schichtstärke der Kunstharzkleberschicht liegt etwa zwischen 0,2 mm und 1,50 mm, je nachdem welche Anforderungen an die Wandverkleidung gestellt werden. Die Kunstharzkleberschicht hat u. a. die Aufgabe, die Hartschaumisolierschicht gegen chemische und mechanische, wetter- und klimabedingte Einwirkungen, Ultraviolett- und Wärmestrahlen zu schützen, das Armierungsstahlgitter vollflächig und festhaftend mit der Hartschaumisolierschicht zu verbinden und die Haftfestigkeit des Deckputzes zu erhöhen und dessen Applizierung zu erleichtern.
Das nichtrostende und schiebefeste Stahlgitter vervielfacht die Druck-, Biege-, Zug- und Scherfestigkeit sowie die Volumen- und Formbeständigkeit der Verkleidung. Da der lineare thermische Ausdehnungskoeffizient des verschweissten Stahlgitters etwa achtmal geringer ist als z. B. derjenige von Polystyrol-Hartschaumplatten, sind die thermisch bedingten Kontraktionen an den Plattenstössen derart gering, dass kaum die Gefahr von Deckputzrissen und Kältebrücken besteht, umsoweniger wenn die Plattenstösse noch mit einem gitterartigen Armierungsstreifen überdeckt sind oder die Stahlgitterarmierung an den Plattenstössen überlappend ausgeführt ist.
Stärke und Maschenweite des Stahlgitters können den bautechnisch erforderlichen Eigenschaften angepasst werden. Bei relativ dünnschichtigen Kunststoffdeckputzen von 2 bis 4 mm hat sich ein Stahlgitter von zirka 1,50 bis 2,0 mm Stärke und zwischen 6 und 15 mm Maschenweite als zweckmässig erwiesen. Die Möglichkeit der mechanischen Verbindung der Verkleidung mit der Gebäudewand erbringt eine Reihe von bautechnischen und wirtschaftlichen Vorteilen.
Wall cladding made from thermally insulating composite hard foam panels
Such wall coverings are well known.
In the various types of construction, however, deficiencies occur again and again, such as insufficient protection of the coatings and rigid foam panels against mechanical and chemical effects, changes in volume and shape of the cladding that lead to cracks, moisture penetration and cold bridges, insufficient adhesion of the cladding to the building wall and the coatings among themselves.
The invention, which overcomes these disadvantages, is characterized in that the outer surfaces of the rigid foam panels are glued over the entire surface with a shrink-free and hydrophobic, vapor-permeable synthetic resin adhesive layer and this is bonded to a reinforcement layer in the form of a rustproof and non-sliding steel grid, the joints of the composite rigid foam panels with a second reinforcement layer are covered and the wall cladding is provided with a cover layer adhering partly to the synthetic resin adhesive layer and partly to the reinforcement layer.
An example of the inventive concept is shown in the drawing. The figure shows a section of the wall covering.
Large-area composite hard foam panels, which consist of a hard foam panel 2, a synthetic resin adhesive layer 3 and a reinforcement layer 4, are pegged in place with nails or screws 5 on a building wall 1. The plate joints 6 are tightly closed 7. The plate joints 6 are covered with a second reinforcement layer 8. The wall cladding, which is made so flat, flush and tight, is provided with a finishing plaster 9 which adheres partly to the synthetic resin layer and partly to the reinforcement layer.
The synthetic resin adhesive layer 3 hardens without shrinkage or cracks and is vapor-permeable, so that the shape and volume as well as the breathability of the composite panel are retained. The thickness of the synthetic resin adhesive layer is approximately between 0.2 mm and 1.50 mm, depending on the requirements placed on the wall cladding. The synthetic resin adhesive layer has u. a. the task of protecting the rigid foam insulating layer against chemical and mechanical, weather and climate-related effects, ultraviolet and heat rays, connecting the reinforcing steel grille with the rigid foam insulating layer over the entire surface and increasing the adhesive strength of the top plaster and making its application easier.
The non-rusting and non-sliding steel grille multiplies the compressive, flexural, tensile and shear strength as well as the volume and shape retention of the cladding. Since the linear thermal expansion coefficient of the welded steel mesh is about eight times less than z. B. that of polystyrene foam panels, the thermally induced contractions at the panel joints are so small that there is hardly any risk of plaster cracks and thermal bridges, and even less if the panel joints are still covered with a grid-like reinforcement strip or the steel mesh reinforcement on the panel joints is designed to overlap.
The thickness and mesh size of the steel mesh can be adapted to the structural properties required. In the case of relatively thin-layer plastic finishing plasters of 2 to 4 mm, a steel mesh with a thickness of approximately 1.50 to 2.0 mm and a mesh size of between 6 and 15 mm has proven to be useful. The possibility of mechanical connection of the cladding with the building wall brings a number of structural and economic advantages.
