Description

Beschreibung der Zusatzpatentanmeldung Nr. P 17 84 910,4-25 Hilfsspanngl ieder für das Drehverfahren von Bau- teile@`dem Verfahren (Hauptpatentanmeldung Nr. P 16 84 464.7) zur Herstellung von Staklbetox-und Spannbe tontragwerken, Das Verfariren wird anhand der beigefügten Figuren 1 und 2 beschrieben. Fig. 1 zeigt eine Längsansicht eines nach dem Hauptverfahren bereits in die hordzontale Zage geschwenkten Traggliedes (40). Das bereits erstellte zurückliegende Tragglied ist mit (41) angedeutet. Zum Schwenkvorgang wurde das Schwenkglied (40) zur mit den Strichpunkt dargestellten Hilfssspanngliedgru,ppen (42),(43).(44) ausgerüstet, die ausserhalb des Betonquerschnitten liegen. Wahrend des Gleitvorganges in Gleitschalung war somit der Aufwand von beim Gleiten einzubauenden Spanagliedurn bezw. Hüllrohren nicht erforderlich. Es musste nur die relativ schwache schlaffe Armierung verlegt werden. Diese Hilfsspaanglieder sind auch in Fig. 2 zu sehen, Fig. 2 zeigt den Querschnitt a-a von Fig. 1. Man erkennt, dass durch Überlappung über der Stütze mehr Spannglieder lieget und dass sich die Spaangliedgruppex (42) und (43) voneinander getrennt bei (45) bezw. (46) einseitig verankern lasen bezw. bei (47) und (48) einseitig vorspannen lassen. Verankerung und Vorspannung könnest im Steg oder ix verü1eibenden Ortbetonquerbalken untergebracht werden.Description of the additional patent application no. P 17 84 910.4-25 Auxiliary tendons for the turning process of structural share @ `the procedure (main patent application no. P 16 84 464.7) for the production of staked concrete and prestressed concrete structures. The processing is described with reference to the attached FIGS. 1 and 2. Fig. 1 shows a longitudinal view of a support member (40) that has already been pivoted into the hordzontal frame according to the main method. The previous supporting member that has already been created is with (41) indicated. For the pivoting process, the pivoting member (40) was equipped for auxiliary tendon groups (42), (43). During the sliding process in the sliding formwork, the effort of the Chipagliedurn to be installed when sliding was resp. Ducts not required. Only the relatively weak, slack reinforcement had to be laid. These auxiliary tension members can also be seen in FIG. 2, FIG. 2 shows the cross section aa of FIG (45) resp. (46) anchored on one side or at (47) and (48) have one side pretensioned. Anchoring and prestressing can be accommodated in the web or ix remaining in-situ concrete crossbeams.

Hilfsspaniigliedgruppe (44) wird entbehrlich, wenn sich durch den Drehvorgang ein genügendes Kragmoment eingestellt hat.Auxiliary chip member group (44) can be dispensed with when a sufficient cantilever moment has been established by the turning process.

Die oberen Hilfsspannglieder z.B. (42) werden im Punkt (49) durch ein Querelement umgelenkt, bei (50) durch eine Aussparung der Oberplatte geführt und über einen Hilfapylon (51) (in Fig, 1 und 2 zu sehen) ausserhalb des Querschnittes antimetrisch auf die andere Schwenkseite geführt. Der hilfspylon (51) kann ein wieder- verwendbares Stahlbetonfertigteil sein auf Neoprenekissen 0,q, gleich (52) ruhen. nachdem der Schwenkvorgang beendet ist, die beiden Schwenkglieder durch eizie Hilfskonstruktion miteinander fest verbunden sind und eine Schalungsma:ischet@e zur Ausbetonierung des Spaltes eingebracht ist, können die endgültigen Spannglieder verlegt werden. Da die Vorbaurichtung bei Fig, 1 von links nach rechts geht, wird zunqchst die linke erdgültige Spanngliedgruppe (53) (gepunktet gezeichnet) neben den Stegen verlegt und bei (54) mit den Spanngliedern des Vorbauteiles im Spalt im Bereich der* Unterplatte (55) gekoppelt. Dann wird diese Spanngliedgruppe bei (56) in einer Pressenniesche des Steges (56) vorgeepanat, nachdem die Hüllrohre der Spanngliedgruppe (53) durch Klappeisen und-Ortbeton bei (57) schubfest mit den Stegen verbunden sind. Zug um Zug wird gleichzeitig die Vorspannungv der Hilfsspanngliedgruppe (42) genau nach statische Erfordernissex nachgelassen, die Spanngliedgruppe (42) kann entfernt werden. Für den rechten Kragarm verbleibt nur noch die Hilfsspanngliedgruppe (43). Nach, diesem scnematisiertex Beispiel, das viele Varianten offenlässt, geht es dann feldweise entsprechend weiter. Unter (58) sind in den Fig. 1 und 2 die Brückenpfeiler, unter (59) die Drehgelrnke angedeutet.The upper auxiliary tendons, for example (42), are deflected at point (49) by a transverse element, guided at (50) through a recess in the top plate and antimetrically open via an auxiliary pylon (51) (seen in FIGS. 1 and 2) outside the cross-section the other swivel side out. The auxiliary pylon (51) can be used again usable precast reinforced concrete part on neoprene cushions 0, q, equal to (52) rest. After the pivoting process is finished, the two pivoting members are firmly connected to each other by an auxiliary construction and a formwork dimension: ischet @ e has been introduced for concreting the gap, the final tendons can be laid. Since the front end direction in Fig. 1 goes from left to right, the left earthly tendon group (53) (shown in dotted lines) is laid next to the webs and at (54) with the tendons of the front end part in the gap in the area of the * lower plate (55) coupled. Then this group of tendons is pre-peened at (56) in a press recess of the web (56), after the ducts of the group of tendons (53) are shear-proof by flap iron and in-situ concrete at (57) are connected to the webs. Step by step, the prestressing of the auxiliary tendon group becomes simultaneously (42) released exactly according to static requirementsx, the tendon group (42) can be removed. Only the auxiliary tendon group (43) remains for the right cantilever arm. After this simplified example, which leaves many variants open, it then continues accordingly field by field. The bridge piers are indicated under (58) in FIGS. 1 and 2, and the rotary joints are indicated under (59).
