Abstract

The double-wall plastics panels (1) have vertical partitions (2) between the inner and outer skins, forming hollow, square-section vertical cells (7). Brackets (3c) can be attached to the panels for use as supports for pipes, cables etc., or for clamping two panels together to form a butt joint. When used for a joint, the bracket can form a connection to e.g. a vertical angle (20), forming part of a supporting structure. The bracket has two parallel slots (23) into which are inserted two prongs (25) of a U-shaped locking member (26). All types of supports or brackets include an arm (6) with a curved free end (9) which is inserted in a hole (8) through the inner skin, so as to fit inside a vertical cell. One type fitting may consist of a threaded stem with a nut for retaining an angle-shaped cleat, attached to such the bracket arm. Other fittings may be used for different joints.

festigung von Hohlkammerplatten Zusatz zu Patent ... (Patentanmeldung P 30 34 129.8) Das Hauptpatent betrifft ein Befestigungselement mit einem Anschlußteil für die Befestigung von Hohlkammerplatten, die aus Ober- und Untergurtplatten sowie Kammern bildenden Stege bestehen, wobei das Befestigungselement wenigstens einen in die Kammer der Hohlkammerplatte einschiebbaren Trägerbalken aufweist, an dessen einen Ende das Anschlußteil in einem vorzugsweise rechten Winkel zum Trägerbalken angeordnet ist. Fixing of twin-wall sheets Addendum to patent ... (patent application P 30 34 129.8) The main patent relates to a fastening element with a connector for fastening twin-wall sheets made from upper and lower chord sheets as well as There are webs forming chambers, the fastening element at least one has in the chamber of the twin-wall sheet insertable support beam, on the one end of the connector at a preferably right angle to the support beam is arranged.

Zur Befestigung von bspw. aus Polykarbonat, Polypropylen oder ähnlichen Kunststoffen bestehenden Hohlkammerplatten an Unterkonstruktionen mit Querstreben ist es wünschenswert, die Hohlkammerplatten zunächst mit den Befestigungselementen zu versehen und danach die gesamte Platte an den Querstreben aufzuhängen. Da derartige Platten in der Regel für Verscheibungen insbesondere von Gewächshäusern verwendet werden und damit Witterungseinflüssen ausgesetzt sind, ist ferner notwendig, daß die Befestigung Wärmedehnungen der Platte einerseits zuläßt und anderseits keine undichten Stellen hinterläßt.For fastening, for example, made of polycarbonate, polypropylene or the like Plastics existing twin-wall sheets on substructures with cross struts it is desirable to first place the twin-wall sheets with the fasteners to provide and then hang the entire plate on the cross braces. Since such Panels are usually used for glazing, especially in greenhouses and are thus exposed to the elements, it is also necessary that the attachment allows thermal expansions of the plate on the one hand and none on the other leaves leaks.

Der Erfindung liegt daher die Aufgabe zugrunde, das Hauptpatent derart zu verbessern, daJ3. solche BeSestigungen möglich snd.The invention is therefore based on the object of the main patent in such a way to improve that 3. such attachments are possible.

Er,findungsgemäß wird dies dadurch erreicht, daß das Anschlußteil mit zwei im Abstand zueinander angeordneten Durchbrechungen versehen ist, il die ein U-förmiges Halteteil mit seinen beiden an einem Endz über einen Steg verbundenen freien Schenkel eir hieb- und in Endstellung arretierbar ist.He, according to the invention, this is achieved in that the connector is provided with two spaced apart openings, il the a U-shaped holding part with its two connected at one end via a web free leg eir cut and can be locked in the end position.

Nach Herstellung der Bohrungen für die Trägerbalken des Befestigungselementes in die Untergurtplatte der Hohlkammerplatte wird das Befestigungselement in die Kammern der Hohlkammerplatte eingehängt. Zum Einhängen werden die Trägerbalken zunächst mit ihrer Längsachse zur Bohrung fluchtend angesetzt und danach durch eine kreisähnliche Bewegung eingeschoben. Die zweiteilige Ausführung des Befestigungselementes ermöglicht auch dann ein Einhängen in die Hohlkammerplatten, wenn die Schenkel des Halteteils parallel zu den Trägerbalken verlaufen und länger sind als diese. Das Halteteil wird erst nach dem Einhängen durch die Durchbrechungen im Anschlußteil des Befestigungselementes soweit durchgesteckt, bis der die beiden Schenkel verbindende Steg an der Außenfläche des Anschlußteiles anliegt. Diese Endstellung wird durch entsprechende Maßnahmen arretiert. Der Abstand der beiden Schenkel des Halteteiles ist so gewählt, daß nunmehr die Hohlkammerplatte über die Querstrebe der Unterkonstruktion eingehängt werden kann. Durch die Abstimmung der Länge der Schenkeln auf die Breite der Querstreben ist das Befestigungselement in der Lage, auch große Wärmedehnungen der Hohlkammerplatte auszugleichen ohne außer Eingriff zu kommen. Das erfindungsgemäße Befestigungselement erlaubt auch dann die Befestigung der Hohlkammerplatten an eine Unterkonstruktion, wenn von der Innenseite her keine Zugriffsmöglichkeit zu den Quer streben besteht. Ein derartiger Anwendungsfall liegt dann vor, wenn die Hohlkammerplatten als Wärmedämmung an bereits mit Glas verscheibten Gewächshäusern angebracht werden. Besteht eine Zugriffsmöglichkeit zu den Querstreben wird die Hohlkammerplatte mit den eingesetzten Befestigungselementen gegen die Unterkonstruktion gedrückt und danach die Halteteile durch die Durchbrüche des Anschluß teiles und über die Querstrebe ge schoben.After making the holes for the support beams of the fastening element The fastening element is inserted into the lower chord plate of the twin-wall sheet The chambers of the twin-wall sheet are suspended. The girder beams are first used for hanging with its longitudinal axis aligned with the hole and then by a circle-like one Movement inserted. The two-part design of the fastener makes it possible also hooking into the twin-wall sheets when the legs of the holding part run parallel to the support beams and are longer than these. The holding part is only after hanging through the openings in the connection part of the fastener pushed through until the web connecting the two legs is on the outer surface of the connector is applied. This end position is achieved through appropriate measures locked. The distance between the two legs of the holding part is chosen so that now the twin-wall sheet can be hung over the cross brace of the substructure can. By matching the length of the legs to the width of the cross braces the fastening element is able to withstand large thermal expansions of the twin-wall sheet balance without disengaging. The fastening element according to the invention allows the twin-wall sheets to be attached to a substructure, if there is no access to the cross struts from the inside. Such an application occurs when the twin-wall sheets are used as thermal insulation can be attached to greenhouses already covered with glass. Is there a Access to the cross struts is provided by the twin-wall sheet with the inserted Fastening elements pressed against the substructure and then the holding parts through the openings of the connection part and pushed ge over the cross strut.

in einer weiteren Ausgestaltung der Erfindung können die Durchbrechungen einen dem Schenkelprofil des Halteteils angepaßten rechteckigen Querschnitt aufweisen. Durch diese Gestaltung ergibt sich eine großflächige Abstützung des Halteteils an der Querstrebe der Unterkonstruktion.In a further embodiment of the invention, the openings have a rectangular cross-section adapted to the leg profile of the holding part. This design results in a large-area support of the holding part the cross brace of the substructure.
