Description

Im Patent 898 077 zur Erfindung ist ein allseitig geschlossener Kastenträger aus Beton für schalungslose Deckenkonstruktionen beschrieben, welcher als besonderes Merkmal die Unterteilung durch Querstege aufweist.In patent 898 077 for the invention, a box girder made of concrete that is closed on all sides is described for ceiling structures without shuttering, which has a special feature that is subdivided by transverse webs.

Um bei den verlegten Trägern dieser Bauart die Lasten verteilende Wirkung in der Querrichtung zu erhöhen, sind die Träger gemäß der Erfindung so ausgebildet, daß sie nach dem Verlegen die Möglichkeit bieten, eine die einzelnen Träger verbindende Querrippe herzustellen. Zu diesem Zwecke werden in den Längsstegen -der Träger, und zwar vornehmlich in der unteren Hälfte, an den Stellen, wo die Bewehrung der Querrippe liegen soll, Aussparungen und zu beiden Seiten dieser Aussparungen Querstege in einem Abstand vorgesehen, welcher der gewollten Breite der Querrippe entspricht. An derselben Stelle werden im Obergurt -des Trägers Öffnungen ausgespart. Werden nun die Träger dicht an dicht verlegt, so liegen die Stegaussparungen in einer Flucht, so daß die Möglichkeit gegeben ist, quer durch die Trägerdecke Bewehrungseisen einzubringen und :den Hohlraum durch,die Öffnungen im Obergurt mit Beton .auszugießen. Auf diese Weise entsteht somit eine Querrippe aus Beton, die eine Stahlbewehrung besitzt und alle Träger der Decke kraftschlüssig faßt.In order to distribute the loads in the laid girders of this type To increase the effect in the transverse direction, the carriers according to the invention are designed so that after laying they offer the possibility of connecting the individual carriers Produce cross rib. For this purpose, in the longitudinal webs -the carrier, namely mainly in the lower half, in the places where the reinforcement of the Cross rib should lie, recesses and cross webs on both sides of these recesses provided at a distance which corresponds to the desired width of the transverse rib. At the same point, openings are made in the upper belt of the girder. Will Now the girders are laid close together so that the web recesses are in alignment, so that there is the possibility of inserting reinforcing iron across the girder ceiling and: pour the cavity through the openings in the top flange with concrete. To this Thus, a transverse rib made of concrete is created, which has a steel reinforcement and all beams of the ceiling frictionally grips.

Der Erfindungsgegenstand ist in der Zeichnung in einem Ausführungsbeispiel dargestellt, und zwar zeigt Fig. z einen Mittellängsschnitt durch den Träger mit Querrippe, Fig. z eine Draufsicht auf einen Deckenausschnitt und Fig.3 ein Mittellängsschnitt durch die Querrippe.The subject of the invention is shown in the drawing in an exemplary embodiment shown, namely Fig. Z shows a central longitudinal section through the carrier with Transverse rib, FIG. Z is a plan view of a ceiling section and FIG. 3 is a central longitudinal section through the cross rib.

Der Kastenträger a weist an .der Stelle, wo nach .dem Verlegen die Querrippe b liegen soll, zwei Querstege c auf, deren Abstand voneinander der kippenbreite entspricht. Inder unteren Hälfte der Stege sind Aussparungen f angeordnet, in welche das Bewehrungseisen d eingebracht wird, während die Öffnungen e im Obergurt der Träger vorgesehen sind, um die darunterliegenden Hohlräume g und die Aussparungen f mit Gußbeton ausfüllen zu können.The box girder a indicates .the place where after .the laying the Cross rib b should lie, two cross webs c, the distance from each other of the tilt width is equivalent to. In the lower half of the webs there are recesses f, in which the rebar d is introduced, while the openings e in the top flange of the Carriers are provided around the underlying cavities g and the recesses f to be able to fill with cast concrete.
