Abstract

An overall monolithic structure is produced by subsequently completing wide-span structures, esp. bridges, withthe core cross-section (1)constructed in a cyclic forwarding process, using reinforced or prestressed concrete units. After forwarding the core cross-section, the missing cross-section parts are built on as prefabricated components (2) and integrated onto the core structure by joint casting. Requisite supports (3) may be concreted behind the abutment. The process is rapid, with min. forme work, and no danger of crack formation.

Description

VERFAHREN ZUR HERSTELLUNG VON BAUWERKEN DURCH TAKT-PROCESS FOR MANUFACTURING BUILDINGS BY TACT

SCHIEBEN MIT NACHTRÄGLICHER ERGANZUNG DER NUTZFLÄCHEN Die Neuerung betrifft die nachträgliche Ergänzung von Bauwerken, insbesondere von-Brücken aus Stahlbeton oder Spannbeton, deren Kernquerschnitt 1 im Taktschiebeverfahren hergestellt wird. Durch Stahl- oder Spannbetonfertigteile 2 wird der Querschnitt so ergänzt, dass ein monolithisches Gesamtbauwerk entsteht.SLIDING WITH SUBSEQUENT EXTENSION OF USEFUL AREA The innovation relates to the subsequent addition of structures, in particular from bridges Reinforced concrete or prestressed concrete, the core cross-section of which is 1 produced using the incremental launching process will. The cross-section is supplemented by prefabricated steel or prestressed concrete elements 2 so that that a monolithic overall structure is created.

Bei der Herstellung breiter, weitgespannter Bauwerke im Taktschiebeverfahren ist es sinnvoll, zunächst nur den Kernquerschnitt vorzuschieben und Teile der späteren Nutzfläche nachträglich zu ergänzen. Die Reduzierung der Querschnittsfläche und des Eigengewichts im Verschiebezustand erspart Betonstahl und Spannstahl und ermöglicht bei gleicher Bauhöhe grössere Spannweiten.In the manufacture of wide, wide-span structures using incremental launching it makes sense to initially only advance the core cross-section and parts of the later Usable area to be added later. Reducing the cross-sectional area and of its own weight in the shifted state saves reinforcing steel and prestressing steel and enables Larger spans with the same overall height.

Die Herstellung von Bauwerken nach dem Taktschiebeverfahren ist bekannt (Deutsches Patent Nr. 1237 603) und hat sich in weiten Bereichen als technisch und wirtschaftlich beste Lösung erwiesen. Die Herstellung und das Verschieben des vollen Querschnitts führt jedoch in den o.g. Fällen zu Nachteilen. Es sind daher Bauwerke ausgeführt worden, bei denen nachträglich der im Taktschiebeverfahren hergestellte Kernquerschnitt durch Ortbetonteile ergänzt wurde.The manufacture of structures using the incremental launching method is known (German Patent No. 1237 603) and has proven itself in wide areas as technical and economically proven to be the best solution. Making and moving the full However, cross-section leads to disadvantages in the above-mentioned cases. They are therefore structures have been carried out, in which the incremental launching method subsequently produced Core cross-section was supplemented by in-situ concrete parts.

Da dies erst durchgeführt werden kann, nachdem der Taktschiebevorgang abgeschlossen ist, führt dies entweder zu einem erheblichen Schalaufwand oder zu einer wesentlichen Bauzeitenverlängerung. Weiterhin wird dadurch Beton sehr unterschiedlichen Alters, Feuchtigkeitsgehalts und Temperatur miteinander verbunden, was zu Rissen im Bereich der Kontaktfuge führen kann.Since this can only be done after the clock shifting process is completed, this either leads to a considerable amount of formwork or to a significant extension of the construction period. Furthermore, this makes concrete very different Age, moisture content and temperature are interrelated, resulting in cracks can lead in the area of the contact joint.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen und die nachträgliche Ergänzung der Nutzflächen kurzfristig und weitgehend zwängungsfrei zu ermöglichen.The invention is based on the object of eliminating these disadvantages and the subsequent addition of the usable space at short notice and largely free of constraints to enable.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass zur Ergänzung der Nutzflächen Stahl- oder Spannbetonfertigteile verwendet werden, die in den genannten physikalischen Bedingungen dem Kernquerschnitt entsprechen und die durch Vergiessen der Fugen mit Beton- oder Kunstharz-Mörtel mit dem Kernquerschnitt monolithisch verbunden werden. Der Kernquerschnitt wird dabei im Taktschiebeverfahren so hergestellt, dass die unterstützenden Tragglieder der Fertigteile zusammen mit dem Kernquerschnitt hinter dem Widerlager betoniert werden oder nach dem Verschieben als Fertigteile zu montieren sind. Weiterhin werden die Fertigteile so gestaltet, dass mit wenig Material- und Zeitaufwand die Fugen zu schliessen sind.According to the invention, this object is achieved in that to supplement of the usable areas pre-fabricated steel or prestressed concrete elements are used, which are specified in the physical conditions correspond to the core cross-section and those by potting the joints with concrete or synthetic resin mortar with the core cross-section monolithic get connected. The core cross-section is produced using the incremental launching process so that that the supporting members of the precast elements together with the core cross-section be concreted behind the abutment or as prefabricated parts after moving are to be assembled. Furthermore, the prefabricated parts are designed so that with little Material and time required to close the joints.

Der erzielte Vorteil der Erfindung liegt zunächst darin, die Nutzfläche in kurzer Zeit ergänzen zu können. In der Regel erlauben erst dadurch die Bautermine die Aufteilung der Ausführung in Kernquerschnitt im Taktschiebeverfahren und anschliessende Ergänzung. Weiter verhindert die Verwendung von Fertigteilen die Entstehung von Rissen aus Zwang und ermöglicht die Reduzierung der sonst erforderlichen Bewehrung. Ausserdem ergibt die Verwendung von Fertigteilen eine besonders wirtschaftliche Gestaltung und Ausführung der nachträglich zu ergänzenden Nutzflächen.The advantage achieved by the invention is first of all the usable area to be able to supplement in a short time. As a rule, only then allow the construction dates the division of the execution into core cross-section in incremental launching and subsequent Complement. Furthermore, the use of prefabricated parts prevents the formation of Cracks out of constraint and enables the reduction of the reinforcement otherwise required. In addition, the use of prefabricated parts is particularly economical Design and implementation of the usable areas to be supplemented at a later date.

Die Erfindung wird durch folgende Figuren erläutert: Fig. 1 zeigt den Querschnitt eines Tragwerkes mit nachträglicher Ergänzung des Kernquerschnitts durch Fertigteile.The invention is illustrated by the following figures: FIG. 1 shows the cross-section of a structure with subsequent addition of the core cross-section through prefabricated parts.

Fig. 2 zeigt im Querschnitt die Verbindung zweier Kernquerschnitte durch eine nachträgliche Ergänzung.Fig. 2 shows in cross section the connection of two core cross sections through a subsequent addition.

Fig. 3 zeigt in der Draufsicht versetzte Querstösse der Fertigteile.Fig. 3 shows offset transverse joints of the finished parts in plan view.

Zunächst werden ein- oder mehrere Kernquerschnitte 1 im Taktschiebeverfahren hergestellt und in die endgültige Stellung über den Pfeilern 2 verschoben. Die quer verlaufenden Unterstützungen 3 für die längs gespannten Fertigteile werden zusammen mit den Kernquerschnitt hergestellt und verschoben. Die Unterstützungen 3 können durch Tragglieder 4 aus Ortbeton oder Fertigteilen nach dem Verschieben ergänzt werden. Auf die Unterstützungen 3 oder die Tragglieder 4 werden die Fertigteile 5 gelegt. Durch Ausbetonieren oder Vergiessen mit Kunstharz werden die Fugen 6 gefüllt.First, one or more core cross-sections 1 are incremented using the incremental launching method produced and moved into the final position above the pillars 2. The cross running supports 3 for the longitudinally tensioned prefabricated parts are together made with the core cross-section and shifted. The 3 supports can supplemented by support members 4 made of in-situ concrete or prefabricated parts after moving will. The prefabricated parts 5 are placed on the supports 3 or the support members 4. The joints 6 are filled by concreting or casting with synthetic resin.

Durch versetzte Anordnung der über mehrere Quer felder gespannten Fertigteile 5 lässt sich entsprechend Figur 3 der Anteil der Stösse über den einzelnen Unterstützungen verkleinen.By staggered arrangement of the spanned across several transverse fields Finished parts 5 can be according to Figure 3, the proportion of the impacts over the individual Reduce supports.
