Description

Gegen Fliegerbomben gesicherte Dachbedeckung aus Schutzplatten mit mehreren maschenförmigerßeivehrungsschichten Die Erfindung betrifft eine gegen Fliegerbomben gesicherte Dachbedeckung aus Schutzplatten mit mehreren maschenförmigen Bewehrungsschichten, die durch mit Kerben versehene, durch Verdrehen verriegelbare Stege im Abstand gehalten werden, nach Patent 690 7¢5. Im Hauptpatent sind an den Seitenwänden dieser Stege aderartig in die Betonschicht hineinragende Drahtbüschel vorgeschlagen worden, die die Aufgabe haben, die Betonschicht in sich noch besser gegen Splittern zu schützen. Gemäß der Erfindung werden an Stelle dieser Drahtbüschel gelochte, vorzugsweise wellenförmig geriffelte Bleche angeordnet, die elastisch von der Stegebene abfedern. Sie haben ebenfalls die Aufgabe, gegen Splittern zu sichern und erreichen das dadurch, daß durch die Löcher hindurch Betonstege stehenbleiben. Diese Bleche lassen sich aber billiger herstellen und anbringen als die Drahtbüschel. Sie verhalten sich auch vorteilhafter beim Einführen dieser Stege in die Masche. Es ist vorteilhaft, die Löcher so auszubilden, daß möglichst lange Fransen bei der Lochbildung stehenbleib:en, die nach dem Stege hinzeigen. Dadurch kann man sich weniger leicht reißen, wenn diese Stege eingesetzt werden.The invention relates to a roof covering, secured against aircraft bombs, made of protective plates with several mesh-shaped reinforcement layers, according to patent 690 7 [5]. In the main patent, wire tufts protruding like a vein into the concrete layer have been proposed on the side walls of these webs, which have the task of protecting the concrete layer even better against splinters. According to the invention, instead of these wire tufts, perforated, preferably corrugated metal sheets are arranged, which cushion elastically from the web level. They also have the task of protecting against splinters and achieve this by stopping concrete bars through the holes. However, these sheets can be manufactured and attached more cheaply than the wire tufts. They also behave more advantageously when inserting these webs into the mesh. It is advantageous to design the holes in such a way that fringes that are as long as possible remain when the holes are formed, pointing towards the web. This makes it less easy to tear when these bars are used.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Fig. r zeigt einen solchen Steg perspektivisch und Fig. a ein Stück Blech mit fransenartig ausgebildeten Löchern. Geriffelte Bleche t sind an den Seitenwänden des Steges a befestigt, beispielsweise durch Schweißpunkte 3 oder Schweißnähte q.. Sie sind wellenförmig ;gebogen und mit Löchern 5 versehen. Beim Bilden der Löcher 5 ist das Ausbruchmaterial stehengeblieb:en, so daß nach der Stegseite hin fransenförmige Ränder 5a entstehen. So liegt die glatte Seite der federnden Bleche außen, so daß der Steg mühelos durch die Masche gesteckt werden kann. Der Widerstand gegen Lockerung der Schichten durch die sich bildenden Keilwirkungen wird dadurch möglichst groß.Fig. R shows such a web in perspective and Fig. A shows a piece Sheet metal with fringed holes. Corrugated sheets t are on the side walls of the web a attached, for example by welding spots 3 or welding seams q .. They are wave-shaped, curved and provided with holes 5. While making the holes 5 the excavated material has remained standing, so that fringe-shaped towards the web side Edges 5a arise. The smooth side of the resilient metal sheets is on the outside, so that the bar can be easily inserted through the mesh. Resistance to loosening the layers due to the wedge effects that are formed thereby become as large as possible.
