Description
Den Gegenstand der vorliegenden Erfindung bildet ein Blechträger als Rippenbewehrung für schalungsfrei zu verlegende Hohlsteindecken, der aus zwei profilierten Blechen mit je einem Fußflansch besteht, die an Ausdrückungen ihrer Stege miteinander verbunden sind.The subject of the present invention forms a sheet metal support as Rib reinforcement for hollow stone ceilings that can be laid without formwork, consisting of two profiled ones Sheets with one foot flange each are attached to expressions of their webs with one another are connected.
Erfindungsgemäß sind diese Ausdrückungen in den Stegen der profilierten Bleche diagonal so angeordnet, daß die vereinigten Bleche einen Blechträger mit den statischen Eigenschaften eines Gitterträgers bilden.According to the invention, these expressions are profiled in the webs Sheets arranged diagonally so that the combined sheets have a sheet metal support the static properties of a lattice girder.
Hierdurch wird die Festigkeit des Blechträgers erheblich vergrößert, so daß er unter sonst gleichen Verhältnissen aus dünnerem Blech als die bisherigen Blechträger dieser Art hergestellt werden kann und die Stege der profilierten Bleche, aus denen er gebildet ist, zwischen den Ausdrückungen ausgeschnitten sein können. Beide Maßnahmen setzen das Eigengewicht des neuen Blechträgers gegenüber bekannten erheblich herab. Es wird hierdurch nicht nur Material gespart, sondern auch die Handhabung solcher Träger erleichtert.This significantly increases the strength of the sheet metal support, so that, under otherwise identical conditions, it is made of thinner sheet metal than the previous ones Sheet metal supports of this type can be produced and the webs of the profiled sheets, from which it is formed can be cut out between the expressions. Both measures set the dead weight of the new sheet metal support against known ones considerably. This not only saves material, but also that Handling of such carriers facilitated.
In weiterer Ausbildung der Erfindung werden an den Fußflanschen der profilierten Bleche ausgeschnittene Lappen hochgebogen, die den zwischen den Blechträgern eingelegten Hohlsteinen oder Hohlkörpern als Auflager dienen. Infolgedessen wird der Blechträger durch den zwischen den Hohlsteinreihen eingefüllten Beton bis auf die praktisch bedeutungslosen Auflagestellen der Lappen von der Größe der Blechränder dieser Lappen allseitig von Beton umschlossen, was die statischen Eigenschaften der Decke erheblich verbessert.In a further embodiment of the invention, the profiled sheet metal cut-out lobes bent upwards, which between the sheet metal girders inserted hollow stones or hollow bodies serve as supports. As a result, will the sheet metal girder through the concrete filled between the rows of hollow stones except for the practically insignificant support points of the lobes the size of the sheet metal edges this rag enclosed on all sides by concrete, which is the static properties the ceiling improved considerably.
Auch können die den Untergurt des Blechträgers bildenden Längsstreifen der Stege der profilierten Bleche breiter gehalten werden, als die den oberen Längsstreifen der Stege bildenden Obergurte, wodurch die Zugzone der durch die Blechträger und den Füllbeton gebildeten Stahlbetonrippen erheblich verstärkt wird.The longitudinal strips forming the lower chord of the sheet metal carrier can also be used the webs of the profiled sheets are kept wider than the upper longitudinal strips of the webs forming the upper chords, whereby the tensile zone of the sheet metal girders and Reinforced concrete ribs formed by the filler concrete are considerably reinforced.
Für Decken besonders großer Spannweite oder Belastung kann die Zugzone der Stahlbetonbalken noch weiterhin dadurch verstärkt werden, daß man Hohlsteine verwendet, deren das Deckenfeld unterhalb der Blechträger abschließende Fußleisten mit ihrer oberen Begrenzungsfläche so weit herabgezogen sind, daß in die von ihnen gebildeten Nuten ein Bewehrungsstahl eingelegt werden kann, der unterhalb des Blechträgers liegt.The tension zone the reinforced concrete beams can still be reinforced by using hollow stones used, the skirting boards of which conclude the ceiling field below the sheet metal girders with their upper boundary surface are pulled down so far that in those of them formed grooves a reinforcing steel can be inserted below the sheet metal support lies.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.
Die Fig. i und 2 zeigen einen Teil des Blechträgers in Seitenansicht und im Querschnitt, und die Fig. 3 gibt einen Teil einer mit Blechträgern und eingelegten Hohlsteinen hergestellten Decke im Querschnitt wieder.FIGS. I and 2 show part of the sheet metal support in side view and in cross section, and Fig. 3 shows part of a sheet metal supports and inlaid Hollow stone ceiling in cross section again.
Die Stege zweier profilierter Bleche i sind erfindungsgemäß an diagonalen Ausdrückungen 2 miteinander vernietet, verschraubt oder verschweißt, die derart angeordnet sind, daß der Blechträger die statischen Eigenschaften eines Gitterträgers erhält.According to the invention, the webs of two profiled sheets i are on diagonals Expressions 2 riveted together, screwed or welded in such a way are arranged that the sheet metal girder has the static properties of a lattice girder receives.
Zwischen den diagonalen Ausdrückungen 2 sind die
