Abstract
Description
Die vorliegende Erfindung bezieht sich auf Verbindungsbolzen für Träger, und insbesondere auf Verbindungsbolzen mit zylindrischer Form, die in den Flansch eines Stahlträgers eingesetzt werden. Insbesondere sieht die Erfindung einen Verbindungsbolzen mit zylindrischer Form vor, der im unteren Teil mit einem Befestigungsbügel oder im voraus angebrachten Nägeln versehen ist, die pneumatisch in den Flansch eines Stahlträgers eingesetzt werden können, um die Verbindung zwischen einer Betonplatte, die oberhalb der Stahlträger angeordnet wird und den unter ihr befindlichen Stahlträgern zu verstärken.The present invention relates to connecting bolts for beams, and in particular to connecting bolts of cylindrical shape which are inserted into the flange of a steel beam. In particular, the invention provides a connecting bolt of cylindrical shape which is provided in the lower part with a fixing bracket or pre-attached nails which can be pneumatically inserted into the flange of a steel beam in order to reinforce the connection between a concrete slab placed above the steel beams and the steel beams located below it.
Es ist seit einiger Zeit bekannt, Konstruktionen aus Stahl und Beton zu verwenden, insbesondere bei der Herstellung von Platten aus einem Konglomerat, die von Metallträgern getragen werden. Die oben erwähnten Verbindungsbolzen werden einfach elektrisch auf die Oberfläche der Stahlträger aufgelötet und ragen von ihnen in einer Weise vor, daß sie in das Betonbett der Platte eingelagert werden.It has been known for some time to use steel and concrete structures, especially in the manufacture of slabs of conglomerate supported by metal beams. The connecting bolts mentioned above are simply electrically soldered to the surface of the steel beams and project from them in such a way that they are embedded in the concrete bed of the slab.
Die Anbringung dieser Verbindungsbolzen erfordert einen elektrischen Lötvorgang, der an den Trägern ausgeführt, werden muß, nachdem diese bereits montiert sind, was zu Schwierigkeiten führt, die von den Bedienungspersonen nicht immer ohne weiteres überwunden werden können.The installation of these connecting bolts requires an electrical soldering operation to be carried out on the supports after they have already been assembled, which gives rise to difficulties that cannot always be easily overcome by the operators.
Der springende Punkt der vorliegenden Erfindung besteht in der Tatsache, daß der Verbindungsbolzen, nachdem er zunächst mit einem Befestigungsbügel und in den Öffnungen desselben vorab angeordneten Nägeln versehen worden ist, am Flansch des Trägers mittels einer pneumatischen Nietmaschine angebracht werden kann, die die Nägel in den Flansch des baulichen Abschnitts einsetzt, so daß eine vollkommene und stabile Befestigung erzielt wird, sowohl wenn der Verbindungsbolzen unmittelbar am Flansch des Trägers befestigt wird als auch bei Befestigung unter Zwischenfügung einer Platte mit durchbrochener (fret) Form, die den darüber angebrachten Guß der Betonplatte stützt.The key point of the present invention is that the connecting bolt, after having been provided with a fastening bracket and nails pre-arranged in the holes of the same, is fixed to the flange of the beam by means of a pneumatic riveting machine which inserts the nails into the flange of the structural section, so as to obtain a perfect and stable fastening both when the connecting bolt is fastened directly to the flange of the beam and when fastened with the interposition of a fret-shaped plate supporting the cast concrete slab placed above it.
Die Erfindung wird unter Bezugnahme auf die beigefügten Zeichnungen erläutert. In den Zeichnungen stellen dar:The invention is explained with reference to the accompanying drawings. In the drawings:
Fig. 1 eine Ansicht des Verbindungsbolzens gemäß der vorliegenden Erfindung;Fig. 1 is a view of the connecting bolt according to the present invention;
Fig. 2 eine Seitenansicht desselben Verbindungsbolzens;Fig. 2 is a side view of the same connecting bolt;
Fig. 3 eine Draufsicht auf den Verbindungsbolzen im Querschnitt, der auf dem Flansch eines Doppel- T-Trägers ebenfalls als Draufsicht in Querschnitt befestigt ist;Fig. 3 is a plan view of the connecting bolt in cross section, which is attached to the flange of a double-T-beam, also as a plan view in cross section;
Fig. 4 den Verbindungsbolzen, der auf dem Flansch eines Doppel-T-Trägers befestigt ist;Fig. 4 the connecting bolt fixed to the flange of a double-T beam;
Fig. 5 denselben Verbindungsbolzen, der auf einem Doppel-T-Träger unter Zwischenfügung einer Platte mit durchbrochener Form befestigt ist.Fig. 5 the same connecting bolt fixed to a double-T-beam with the interposition of a plate with a perforated shape.
Fig. 1, 2 und 3 zeigen, daß der Verbindungsbolzen aus einem zylindrischen Stab (1) gebildet wird, der mit einem Kopf (2) vergrößerten Durchmessers versehen ist, der durch Kaltstauchen erzeugt wird, und ferner mit einer rechteckförmigen Basisplatte (3) mit zwei seitltchen Schenkeln (4) und (5) versehen ist, die die Konstruktion versteifen und durch Kaltbiegen der Stahlplatte erhalten werden.Fig. 1, 2 and 3 show that the connecting bolt is formed from a cylindrical rod (1) provided with a head (2) of enlarged diameter produced by cold heading and further provided with a rectangular base plate (3) with two lateral legs (4) and (5). which stiffen the structure and are obtained by cold bending the steel plate.
Die Befestigung des Verbindungsbolzens (1) an der Basisplatte (3) wird durch Vernieten des einen verringerten Durchmesser aufweisenden unteren Teils des Verbindungsbolzens (1) erreicht, um dadurch einen konischen Teil (6) zu bilden, der in der Ebene der Unterseite der Platte (3) endet. Die letztere ist mit zwei Löchern (7) und (8) versehen, in die Nägel (9) und (10) eingesetzt werden, wobei die Nägel vorteilhafterweise mit zwei dünnen zylindrischen Hülsen (11) und (12) beschichtet sind, die den Verbleib der Nägel (9) und (10) in den Löchern für die Befestigung oder das Einsetzen wärend der Lagerung als auch während des Transports und bei Durchführung des Befestigungsvorgangs erlauben.The fastening of the connecting bolt (1) to the base plate (3) is achieved by riveting the lower part of the connecting bolt (1) having a reduced diameter, so as to form a conical part (6) ending in the plane of the lower surface of the plate (3). The latter is provided with two holes (7) and (8) into which nails (9) and (10) are inserted, the nails advantageously being coated with two thin cylindrical sleeves (11) and (12) which allow the nails (9) and (10) to remain in the holes for fastening or insertion during storage as well as during transport and when carrying out the fastening operation.
Der Befestigungsvorgang erfolgt mittels einer pneumatischen Nagelmaschine, die auf die Köpfe der Nägel (9) und (10) wirkt, wie in Fig. 4 dargestellt, so daß die Spitzen der Nägel in den Flansch (13) des Eisenträgers eindringen, auf dem der Verbindungsbolzen (1) befestigt werden soll.The fastening operation is carried out by means of a pneumatic nailing machine which acts on the heads of the nails (9) and (10) as shown in Fig. 4, so that the tips of the nails penetrate into the flange (13) of the iron beam on which the connecting bolt (1) is to be fastened.
Das Ziel kann auch mittels Zwischenfügung der in Fig. 5 dargestellten durchbrochenen Platte (14) erreicht werden, wenn die letztere zwischen dem Verbindungsbolzen (1) und dem oberen Flansch des Trägers (13) eingefügt wird.The objective can also be achieved by interposing the perforated plate (14) shown in Fig. 5, if the latter is inserted between the connecting bolt (1) and the upper flange of the beam (13).
Die Vorteile des erfindungsgemäßen Verbindungsbolzens sind offensichtlich, weil der Befestigungsvorgang nicht die Verwendung einer Lötmaschine erfordert, sondern es wird nur eine pneumatische Nagelmaschine benutzt, mittels der die Nägel (9) und (10) auf dem Träger plaziert werden, wobei die Nägel zuvor in der Basisplatte angeordnet werden, wobei durch den Verbindungsbolzen vorteilhafterweise eine Verstärkung erfolgt.The advantages of the connecting bolt according to the invention are obvious because the fastening process does not require the use of a soldering machine, but only a pneumatic nailing machine is used, by means of which the nails (9) and (10) are placed on the support, the nails being previously arranged in the base plate, whereby reinforcement is advantageously provided by the connecting bolt.
