Description

Deckenträger Die Neuerung bezieht sich auf einen Deckenträger, inebe. sondere für Verbunddecken, der zugleich selbsttragende Schalung, Teil der Arbeitsbühne und zum mindesten teilwei- se die Bewehrung darstellt. Dieser Träger ist aus Stahl gewalzt, gepresst oder gegossen oder wird aus mehreren warm-oder kaltgewalzten oder abgekanteten Profilen hergestellt, die z.B. durch Schweissung miteinander verbunden sind. à ist bekannt, Verbunddecken aufzubauen aus Stahlleichtträgern mit aufgelegten Deckenhohlkörpern, die gegebenenfalls mit Lappen unter den Untergurt der Stahlträger herunter- greifen, um eine ebene und materialmässig einheitliche Unteran- sicht der Decke zu erzielen. Diese vorspringenden Lappen an den Steinen brechen wegen ihrer grosses Länge und geringen Dicke sehr leicht ab. Die Neuerung besteht darin, dass der Stahlleichtträger derart unay&eetriach ausgebildet ist, daee dieser Lappen am Decken- stein an seiner Wurzel hinreichend stark ausgebildet werden kann. Zugleich wird gegebenenfalls die eine Seite des Untergurtes derart rinnenförmig gestaltet, dass ein Enlegen von zusätzlicher Rundstahlbewehrung möglich wird. Die Hauptvor- teile dieser unsymmetrischen Anordnung liegen in einer stabi- len Ausführungsform des Deckensteines und in einem grossen Aufnahmeraum für die Zuoatzbewehrumg mit ausreichender Beton- überdeokung. Zur Erhöhung der Schubhaftung kennen in einzelnen Teilen der Träger ausbeulungen, Einkerbungen, Verwölbungen, Löcher oder aufgeschweisste oder angehängte Teile angeordnet werden. Teile des Trägers gegebenenfalls einschliesslich einer eingelegten schlaffen bewehrung werden erforderlichenfalls mit Beton vor dem Verlegen ausgefüllt bzw. but """ Weitere neEL@ and fortschrittliche Merkmale ergeben sich aug der folgenden Beschreibung von Auseihrungsbelepielen in Ver- bindung mit der Zeichnung ar--d den Schutzanepxüchen.

This carrier is rolled, pressed or cast from steel or is made from several hot or cold rolled or folded profiles which are connected to one another by welding, for example. It is known to build composite ceilings from lightweight steel girders with suspended ceiling hollow bodies which, if necessary, reach down under the lower chord of the steel girders with rags in order to create a flat and uniform lower surface. view of the ceiling. These protruding lobes at the stones break because of their great length and shortness Thick very easily. The innovation is that the lightweight steel beam is so unay & eetriach is formed, that this cloth on the ceiling stone can be developed sufficiently strong at its roots. At the same time, if necessary, one side of the lower chord is designed in the shape of a channel in such a way that additional round steel reinforcement is possible. The main advantages parts of this asymmetrical arrangement lie in a stable len embodiment of the ceiling stone and in a large Reception space for the additional reinforcement with sufficient concrete overdecision. To increase the deportation liability know in individual Parts of the carrier bulges, notches, bulges, holes or welded or attached parts are arranged. Parts of the girder, including any slack reinforcement that has been inserted, are filled with concrete before laying """ Further neEL @ and progressive features emerge from aug the following description of award games in different connection with the drawing ar - d the protection requirements.

Fig. 2b shows a similar profile, in which the left lower half of the belt is no longer curved renouncing the option of "additional iron with sufficient to use the overdeokung.

Der Deckenträger nach Fig. 4 hat eine schräg zur Lotrechten liegende Unterkante. Er wird aus zwei Teilen z.B. durch Punktschweissng zusammen gesetzt, der linke Profilteil ist im Un- terteil als weite Rinne 14 ausgebildet, in die erforderlichen- falls Zusatsbewehrangen 15 eingelegt werden, die gegebenen- falls vor dem Trägereinbau mit diesem durch Klammen oder durch Vergusabeton 16 verbunden sind. Das linke grosserie Profil ist oben zweifach zu einem Obergurt 17 abgebogen. Der rechte Pro- filteil 18 besteht aus einem sehiefwinkeligen U-Profil oder aas Winkelprofilen, Z-Profilen oder'U-profilen entsprechend Fig. la-d. Der in Fig. 5a dargestellte Deckenträger ist aus einem Blech- band durch Kaltwalzen und/oder Abkanten hergestellt und da- her in der Fertigung besonders einfach und billig. Der Unter- gart 19 ist rinnenförmig ausgebildet. Die Auflagerkante für den anderen Deckenstein wird durch die Falte 20 dargestellt.The ceiling support according to FIG. 4 has a lower edge which is inclined to the perpendicular. It is made up of two parts, e.g. by spot welding, the left profile part is in the formed as a wide channel 14, in the required- if additional reinforcement 15 are inserted, the given if before the carrier installation with this by clips or through Vergusabeton 16 are connected. The left grosserie profile is bent twice at the top to form a top chord 17. The right pro filteil 18 consists of a deep-angled U-profile or aas Angle profiles, Z-profiles or U-profiles according to Fig. la-d. The ceiling support shown in Fig. 5a is made of a sheet metal tape produced by cold rolling and / or folding and there- particularly easy and cheap to manufacture. The under- gart 19 is designed in the shape of a channel. The support edge for the other ceiling stone is represented by the fold 20.

An den geraden, erforderlichenfalls mit Löchern und Sicken vor dem Kaltwalzen versehenen Steg 21 schließt sich der durch Falten und Abbiegen gebildete Obergurt 22 an, der derart schräg zur Lotrechten liegt, dass der Vergussbeton den Raum unter dem Obergurt gut ausfüllen kann. Fig. 5b zeigt eine weitere, aus einem einzigen Streifen hergestellte Profilform mit rinnenförmigem Untergurt 23, gefalteter rechter Steinauflage 24 und dreieckförmigem Obergurt 25, der durch Verschweißen oder Vernieten zu einem geschlossenen, ausserordentlieh verdrehsteifen querschnitt wird. Das Schliessen zu verdrehsteifen Röhren braucht dabei lediglich über Teile der Trägerlängenzuerfolgen.On the straight ones, if necessary with holes and beads in front of the The web 21 provided with cold rolling closes the one formed by folding and bending Upper belt 22, which is so inclined to the perpendicular that the grouting concrete Can fill the space under the top flange well. Fig. 5b shows another, from one single strip produced profile shape with channel-shaped lower flange 23, folded right stone support 24 and triangular upper belt 25, which by welding or riveting to form a closed, extremely rigid cross-section will. The closing of torsionally stiff tubes only needs parts the carrier lengths.

Fig. 6a zeigt einen Stahlleichtträger, bei dem eine hohe Verdrehsteifigkeit durch streckenweise vorhandene verdrehsteife Verbände erzeugt wird, die dort die Querschnittäverwölbung weitgehend behindern. Durch Schweissen, Nieten oder Kleben am Obergurt 27 and am Steg 28 befestigte Blechstreifen 26 bilden hierbei örtlich Torsionsröhren. In Fig. 6b verbindet ein raohwerksverband 32 den Obergurt 30 und Untergurt 31 und bildet so streckenweise ein verdrehsteifes, räumliches Fachwerk. Löcher oder Sicken 33 im Steg dienen zur Erhöhung der Schubhaftung. In Fig.6c wird der verdrehsteife Verband dadurch gebildet, dass einer oder beide Teile des Leichttrãgers 34 and 35 mit Buckeln 36 versehen sind und die beiden Teile an diesen Stellen z. B. durchSchweissen verbunden sind, sodass jeweils streckenweise Hohlquerschnitte gebildet werden. gohatzansprachc 1) Leichter ststt inabe- sondere für Verbunddecken mit unsymmetrisch abgebildeten Deckenfüllkörpern, dadurch gekennzeichnet, dass der Träger mindestens im Trägerfuss unsymmetrisch ausgeführt ist.6a shows a lightweight steel beam in which a high torsional stiffness is generated by torsionally rigid associations which are present in places and which largely hinder the cross-sectional arching there. By welding, riveting or gluing on the upper chord 27 and sheet metal strips 26 attached to the web 28, locally torsion tubes are formed. In Fig. 6b a framework association 32 connects the upper chord 30 and lower chord 31 and thus in some places forms a torsionally rigid, three-dimensional framework. Holes or beads 33 in the web serve to increase the shear adhesion. In Figure 6c, the torsionally stiff association is formed in that one or both parts of the lightweight carrier 34 and 35 are provided with bosses 36 and the two parts at these points, for. B. are connected by welding, so that Hollow cross-sections are formed in sections. gohatzansprachc 1) Lighter is always especially for composite ceilings with asymmetrically shown Ceiling fillings, characterized in that the carrier is designed asymmetrically at least in the support foot.
