Abstract

The device is developed from a previous system in connection with reinforced-concrete construction. Reinforcement is provided by steel ring balls with a displacement core made of light material. The displacement core may be in the form of a ball of styropor (RTM) or similar plastics material. This constructional system leads to a reduction in the intrinsic weight of the reinforced concrete, and increased proportional load bearing capacity. Heat insulation is increased and costs are reduced.

Description

Auf der Idee der Strahlringku-On the idea of the jet ring

gel aufbauend( Pat.Anmeldg.gel building (patient registration

P 28 24 425.9),schlägt diese Erfindung vor,in die Mitte der Stahlringkugel eine Leichtmaterial-Verdrängungskugel einzubringen,z.B.Styroporkugel oder ähnlich.Siehe dazu Abb.l A+B .Bei der Stahlringkugel nach Abb,l B liegt die Verdrängungskugel genau an der Stelle,an der der Stahl Druck und Zug sowieso sehr gut aufnimmt( Stahl in der Kugelmitte punktgeschweißt ) Es entstehen kugelige geordnete Hohlraume, die sich gleichmäßig über den ganzen Beton verteilen.Siehe dazu Abb.2 sowie Abb.3 .Bei der Stahlringkugel nach Abb.l B wird die Zug- und Druckfestigkeit durch die Verdrängungskugel nicht beeinflußt.P 28 24 425.9), this invention suggests in the middle of the steel ring ball Introducing a light material displacement ball, e.g. a styrofoam ball or similar, see see Fig. 1 A + B. In the case of the steel ring ball according to Fig. 1 B, the displacement ball is located exactly at the point where the steel absorbs pressure and tension very well anyway (steel spot-welded in the center of the sphere) are evenly distributed over the entire concrete, see Fig. 2 and Fig. 3 of the steel ring ball according to Fig. 1 B, the tensile and compressive strength is determined by the displacement ball unaffected.

Als Ergebnis bei Anwendung dieser Erfindung fällt sofort auf,daß es zu einer Eigengewichtsersparnis des Stahlbetons kommt und damit zu einer gesteigerten Fremdgewicht-Tragfähigkeit.Die Eigengewicht Ersparnis beim Stahlbeton nach dieser Erfindung liegt zwischen 5% + 20% .An zweiter Steile sind Vorteile der Erfindung: verbesserte Wärmedämmung sowie Schallschutzeigenschaften und Kostenersparnis durch verringerten Betonverbrauch.As a result of using this invention, it is immediately apparent that it comes to a weight saving of the reinforced concrete and thus to an increased External weight load-bearing capacity. The dead weight savings in reinforced concrete according to this Invention lies between 5% + 20%. Secondly, advantages of the invention are: improved thermal insulation as well as soundproofing properties and cost savings through reduced concrete consumption.

Die Stahlringkugel mit Verdrängungskern ist auch im Spannbeton-Bereich zusätzlich als schlaffe Bewehrung hervorragend geeignet.-Es muß dort ohnehin sehr druckiester Beton verwendet werden,und der hat ein relatif hohes Eigengewicht das durch die Erfindung deutlich reduziert werden kann.The steel ring ball with displacement core is also in the prestressed concrete area also ideally suited as slack reinforcement.-It has to be there anyway High-pressure concrete can be used, and it has a relatively high dead weight can be significantly reduced by the invention.
