Abstract

The reinforced-concrete trusses (1) are suitable for saddleback-roof configuration. By means of a special shuttering technique, the trusses can be manufactured, with a constant roof inclination, in the required length owing to a shuttering length which can be changed easily. By means of a special articulation connection, the truss can be configured, depending on the effective span, as a truss which is supported at one location or two locations. By utilising the large static height provided, a low material and labour outlay is necessary for production.

Description

Bekannt sind Stahlbetonbinder als Biegebalken, die die Dachlast durch ihre Biegesteifigkeit auf ihre Unterstützung übertragen. Die Konstruktionshöhe dieser Balken sind bei Vorfertigung aus Transport-, Herstellungs- und Gewichtsgründen begrenzt, so daß die Ausführung größerer Dachneigungen mit diesen Balken nicht möglich ist.Reinforced concrete trusses are known as bending beams that support the roof load transferred to their support through their bending stiffness. The Construction height of these beams are in prefabrication from transport, Manufacturing and weight reasons limited, so the execution Larger roof pitches are not possible with these beams.

Der Erfindung liegt die Aufgabe zugrunde, Stahlbetonbinder zu ent­ wickeln, die mit geringem Material- und Schalaufwand herzustellen sind und die Ausbildung steilerer Dachneigungen und damit die Ver­ wendung preiswerterer und sicherer Dacheindeckungsmaterialien ermög­ lichen.The invention has for its object to ent reinforced concrete binder wrap that manufacture with little material and formwork are and the formation of steeper roof slopes and thus the Ver use of cheaper and safer roofing materials lichen.

Die Aufgabe wird erfindungsgemäß durch die Merkmale im Kennzeichen des Patentanspruchs 1 sowie des Patentanspruchs 6 gelöst. Zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.The object is achieved by the features in the license plate of claim 1 and claim 6 solved. Appropriate Embodiments of the invention are the subject of the dependent claims.

Die Erfindung ist nachstehend anhand von verschiedenen in den Zeich­ nungen dargestellten Ausführungsbeispielen erläutert. Es zeigtThe invention is based on various in the drawing illustrated embodiments explained. It shows

Der Stahlbetonbinder (1) nach Fig. 1 ist als Satteldachbinder ge­ eignet. Er ist zweifach unterspannt dargestellt. Durch Ausnutzung einer großen statischen Höhe kann er mit geringem Lohn- und Material­ aufwand hergestellt werden. Der Transport und die Montage der Binder ist durch die halbierten Bauteillängen, durch das geringe Gewicht und wegen des einfach auszuführenden Gelenkstoßes, kostengünstig durchzuführen. Die Binder sind, je nach Spannweite, mit einfacher oder zweifacher Unterspannung ausführbar.The reinforced concrete truss ( 1 ) according to FIG. 1 is suitable as a gable roof truss. It is shown in two parts. By using a large static height, it can be manufactured with little wages and material. The transport and assembly of the trusses can be carried out inexpensively due to the halved component lengths, the low weight and the easy to carry out joint joint. Depending on the span, the trusses can be designed with single or double undervoltage.

Die erfindungsgemäße Schaltechnik nach Anspruch 6 ermöglicht es, bei gleichbleibender Dachneigung, durch eine Längenveränderung der Schalung im Mittelbereich (Parallelgurtbinderbereich) die Anpassung der Schalung an die geforderte Binderlänge. Durch die gewählte Gelenkverbindung kann der Zugbalken in einer ge­ sonderten Schalung gefertigt werden.The formwork technology according to claim 6 makes it possible to constant roof pitch, by changing the length of the Formwork in the central area (parallel belt tie area) the adjustment the formwork to the required truss length. Due to the selected articulation, the drawbar can be in a ge special formwork.
