Description
Eisenbeton-Konstruktion. Bisher wurden Eisenbeton-Konstruktio- nen mit Rundeisen bezw. -stahl von verschie dener Qualität und verschiedenem Quer schnitt armiert.
Ferner ist bereits vorgeschlagen worden, bei Plattenbrücken. T-förmige Spannbeton balken als biegungsfeste Träger zu ver wenden.
Die Gegenstand der Erfindung bildende Eisenbeton-Konstruktion ist dadurch gekenn zeichnet, dass ihre Zugarmierung mindestens teilweise durch vorgespannte Betonelemente gebildet ist.
Die vorgespannten Betonelemente können z. B. unregelmässigen, kreisrunden, quadra tischen, rechteckigen oder winkel-profil- förmigen Querschnitt aufweisen.
Ihre Oberfläche kann rauh oder glatt sein, zudem Verzahnungen, Nischen, Buckel auf weisen. Zur schubsicheren Verbindung mit dem Beton können aus den vorgespannten Elementen Bügel vorstehen oder die Ele mente können durchlocht sein.
Die Elemente können einen einzigen oder eine Mehrzahl von vorgespannten Drähten aufweisen. Die Elemente können an der Aussenfläche oder im Innern der Beton- Konstruktion angeordnet sein, und in einer Mehrzahl nebeneinanderliegend oder einzeln die jeweilige Zugarmierung bilden.
Auf beiliegender Zeichnung ist als -Aus führungsbeispiel einer Eisenbeton-gonstruk- tion gemäss der Erfindung ein durchlaufender Träger dargestellt, wobei Fig. 1 einen Teil des Trägers im Längs- schnitt und Fig. 2 den Träger im Querschnitt nach Linie II-II in Fig. 1 zeigt.
Als Zugarmierung besitzt der Träger 1 vorzugsweise fabrikmässig hergestellte, vor gespannte Beton-Elemente 2-, welche zu zweien nebeneinanderliegend zwischen und über den Stützen 3 in den auf Zug bean spruchten Zonen des Trägers angeordnet sind. Die sie verbindende Längsarmierung 4 und die Bügel 5 sind Rundeisen.
Reinforced concrete construction. Reinforced concrete constructions with round bars or - Reinforced steel of various qualities and various cross-sections.
It has also been proposed for plate bridges. T-shaped prestressed concrete beams to be used as rigid beams.
The reinforced concrete structure forming the subject of the invention is characterized in that its tensile reinforcement is at least partially formed by prestressed concrete elements.
The prestressed concrete elements can, for. B. irregular, circular, quadra tables, rectangular or angled profile-shaped cross-section.
Their surface can be rough or smooth, as well as teeth, niches, and humps. For a shear-proof connection with the concrete, brackets can protrude from the prestressed elements or the elements can be perforated.
The elements may have a single or a plurality of pre-tensioned wires. The elements can be arranged on the outer surface or in the interior of the concrete structure and form the respective tensile reinforcement in a plurality of adjacent or individually.
The accompanying drawing shows a continuous girder as an exemplary embodiment of a reinforced concrete structure according to the invention, FIG. 1 showing a part of the girder in longitudinal section and FIG. 2 showing the girder in cross section along line II-II in 1 shows.
As Zugarmierung the carrier 1 has preferably factory-made, pre-tensioned concrete elements 2-, which are arranged to two side by side between and above the supports 3 in the areas of the carrier that are subject to train bean. The longitudinal reinforcement 4 connecting them and the bracket 5 are round bars.
