Abstract

The reinforced-concrete trusses are developed as saddleback-roof trusses. Owing to the connections according to the invention, tie beam (3) and reinforced-concrete beams (2) are to be installed separately, in that, after laying the tie beam (3), the reinforced-concrete beams are simultaneously positioned in each case on the end of the tie beam (3) by means of two cranes and are connected to one another in an articulated manner at the ridge. Owing to the special form of the tie beam (3), intermediate suspension of the tie beam is not necessary. <IMAGE>

Description

Bekannt sind Stahlbetonbinder als Biegebalken, die die Dach­ last durch ihre Biegesteifigkeit auf Ihre Unterstützung über­ tragen. Die Konstruktionshöhe dieser Balken sind bei Vorfer­ tigung aus Transport,- Herstellungs- und Gewichtsgründen be­ grenzt, so daß die Ausführung größerer Dachneigungen mit die­ sen Balken nicht möglich ist.Reinforced concrete trusses are known as bending beams that cover the roof loaded on your support by their bending stiffness wear. The construction height of these beams are at Vorfer due to transport, manufacturing and weight reasons borders, so that the execution of larger roof slopes with the bar is not possible.

Der Erfindung liegt die Aufgabe zugrunde Stahlbetonbinder zu entwickeln, die mit geringem Material- und Schalaufwand her­ zustellen sind und die die Ausbildung steilerer Dachneigungen und damit die Verwendung preiswerterer und sicherer Dachein­ deckungsmateralien ermöglichen.The invention is based on the object reinforced concrete girders develop that with little material and formwork are to be delivered and that the formation of steeper roof slopes and thus the use of cheaper and safer roofs enable cover materials.

Die Aufgabe wird erfindungsgemäß durch die Merkmale im Kenn­ zeichen des Patentanspruchs 1 gelöst. Zweckmäßige Ausgestal­ tung der Erfindung sind Gegenstand der Unteransprüche.The object is achieved by the features in the characteristic Sign of claim 1 solved. Appropriate design tion of the invention are the subject of the dependent claims.

Die Erfindung ist nachstehend anhand von verschiedenen in den Zeichnungen dargestellten Ausführungsbeispielen erläutert.The invention is hereinafter based on various in the Illustrated embodiments illustrated.

Stahlbetonbinder (1) nach Fig. 1 sind durch die erfindungs­ gemäße Verbindung von Stahlbetonbalken (2) mit Stahlbeton­ zugbalken (3) in Einzelteilen zu fertigen. Durch die kreis­ förmigen Anschlußflächen sind diese nur durch Kontakt zwän­ gungsfrei verbunden. Der Radius der Anschlußfläche des Zug­ balkens (3) wird größer als der Radius der Anschlußfläche des Stahlbetonbalkens (2) gewählt. Dadurch wird auch bei plasti­ scher Verformung des Betons im Anschlußbereich eine zentri­ sche Krafteinleitung ohne Zusatzspannungen sichergestellt. Durch die veränderliche Lage des Steges (5) des Zugbalkens (3) werden im Bereich der Wendepunkte der Stegachse Umlenkkräfte notwendig die durch das Eigengewicht des Zugbalkens (3) gebil­ det werden, weil die wesentliche Zugbewehrung im Steg des Zugbalkens (3) angeordnet wird. Dadurch wird es möglich den Zugbalken ohne besondere Aufhängung nur mit Montageabstützung einzubauen.Reinforced concrete girders ( 1 ) according to FIG. 1 are to be manufactured in individual parts by the inventive connection of reinforced concrete beams ( 2 ) with reinforced concrete tension beams ( 3 ). Due to the circular connecting surfaces, these are only connected without contact by contact. The radius of the connecting surface of the tension beam ( 3 ) is chosen larger than the radius of the connecting surface of the reinforced concrete beam ( 2 ). This ensures a centric force transmission without additional stresses even with plastic deformation of the concrete in the connection area. Due to the variable position of the web ( 5 ) of the drawbar ( 3 ), deflection forces are necessary in the area of the turning points of the web axis, which are formed by the weight of the drawbar ( 3 ), because the essential tensile reinforcement is arranged in the web of the drawbar ( 3 ). This makes it possible to install the drawbar without special suspension only with assembly support.
