Description
Verfahren zur Herstellung von Balken. Patentiert im Deutschen Reiche vom .24. Juli 1918 ab. Aus Formsteine doppel-T-förmigen Querschnittes zusammengesetzte Balken werden nach einem bekannten Verfahren in der Weise hergestellt, daß die einzelnen Formsteine gerade zusammengestoß enund durch Bewehrungseisen verbunden werden., welche man in die am Ober- und Untergurt der Steine vorhandenen Rillen einlegt, worauf man letztere samt den Stößen mit Zement ausgießt; hierbei wird die Bewehrung des Obergurtes mit jener des Untergurtes durch in die Stöße der Formsteine verlegte und in dem Zement eingebettete Drahtschleifen oder Bleche miteinander verbunden.Method of making beams. Patented in the German Empire from .24. July 1918 . Bars composed of shaped blocks of double-T-shaped cross-section are produced by a known method in such a way that the individual shaped blocks are just collided and connected by reinforcing iron pour cement together with the joints; Here, the reinforcement of the upper chord is connected to that of the lower chord by wire loops or metal sheets laid in the joints of the shaped stones and embedded in the cement.
Das Zusammenstoßen wurde bisher in der Weise ausgeführt, daß die Ober- und Unter-ULI rtarmierung auf den .ersten Stein verlegt und hierauf auf diese Armierung abwechselnd die vertikalen Bleche und die Steine sozusagen aufgefädelt wurden, während die zum Ausgießen der Zementfugen dienenden Bleche für jeden Balken eine besondere gegenseitige Befestigung notwendig machten.The collision has hitherto been carried out in such a way that the upper and under-ULI reinforcement laid on the first stone and then on this reinforcement alternately the vertical sheets and the stones were strung, so to speak, while the metal sheets used to fill the cement joints have a special one for each beam made mutual fastening necessary.
Durch das in .dein Anspruch gekennzeichnete Verfahren wird sowohl das Einbringen der Armierungen als auch das Befestigen der Abschlußbleche wesentlich erleichtert.The method characterized in your claim will both the introduction of the reinforcements and the fastening of the end plates are essential relieved.
Gegenstand der Erfindung bildet ein Verfahren, welches die Herstellung dieser Balken reihenweise bei möglichster Ersparnis an Zementgußmasse ermöglicht.The subject matter of the invention is a method which makes the production this bar allows rows with the greatest possible saving of cement casting compound.
In Fig. r der Zeichnung ist eine in Herstellung begriffene Balkenreihe in schaubildlicher Ansicht dargestellt.In Fig. R of the drawing is a row of bars being produced shown in a diagrammatic view.
Fig. a und 3 zeigen Einzelheiten.Figures a and 3 show details.
Nach dem den Gegenstand der Erfindung bildenden Arbeitsverfahren wird eine entsprechend vorgerichtete Arbeitsbühne ?n., deren Länge jener der Balken und deren Breite etwa der sechs- bis zehnfachen Balkenbreite entspricht, durch Aufnageln von Latten ia in Rinnen unterteilt, deren lichte Weite die Breite der Untergurte der zur Verwendung gelangenden Formsteine v etwa um 3 bis 5 mm übertrifft. In diese Rinnen werden die zur Bildung des Balkens erforderlichen Steine v unter Belassung.von lichten Stoßfugen von etwa z cm reihenweise verlegt und sodann die mit den Verbindungsblechen c behängten Obergurtarmierungen b, so wie dies an der linken Seite der perspektivischen Darstellung ersichtlich ist, von oben in die Obergurtrillen u eingelegt, so daß die zur Verbindung der Ober- und Untergurtarmierungen dienenden Bleche c in den Stoßfugen frei nach abwärts hängen. Nach dem Einlegen .der Obergurtarmierungen b werden die Untergutarmierungen ä in die von den zusammenstoßenden Untergurtrillen o gebildeten Tunnel von der Stirnseite der Steinreihen aus (siehe zweite Reihe von links) eingeschoben, wobei sie die unteren Ösen d der in den Stoßfugen nach abwärts hängenden Verbindungsbleche c durchdringen, wodurch die beiden Armierungen a, b in den Rillen o, u festgehalten -,verden.According to the working method forming the subject of the invention an appropriately prepared working platform, the length of which is that of the beams and whose width corresponds to about six to ten times the width of the bar, by nailing it on Divided by slats into channels, the clear width of which corresponds to the width of the lower chords of the shaped bricks that are used are exceeded by approximately 3 to 5 mm. In these The stones required for the formation of the beam are v clear butt joints of about z cm laid in rows and then those with the connecting plates c hung upper chord reinforcements b, like this on the left side of the perspective Representation can be seen, inserted from above into the upper chord grooves u, so that the plates used to connect the upper and lower chord reinforcements c in the Butt joints hang freely downwards. After inserting the upper chord reinforcements b the Untergutarmierungen - are in the from the colliding Untergurttrillen o tunnel formed from the face of the rows of stones (see second row of left), with the lower eyelets in the butt joints facing downwards hanging connecting plates penetrate c, whereby the both reinforcements a, b held in the grooves o, u -, verden.
Nunmehr werden die Stoßfugen der in einer Reihe liegenden bzw. zu einem Balken gehörigen Steine v beiderseits durch kurze, an die Seitenflächen der Steine sich eng anschmiegende Bleche t (Fig. 2) überplattet, welche .die Form einer Rinne mit zwei ebenen Flanschen besitzen, und welche vorläufig dadurch festgehalten werden, daß der untere Flansch :2 zwischen dem Untergurt der Steine und der benachbarten Latte n eingeschoben wird. Nach dem in @dieser Weise erfolgten Verlegen der Armierungen a, b und Abschlußbleche t werden die einander gegenüberliegenden Abschlußbleche t durch zwischengetriebene Keile h verspreizt; da dieses Verspreizen durch Keile bei den an den äußeren Seiten der ersten und letzten Steinreihen liegenden Blechen t nicht möglich ist, werden an diesen Stellen Bleche t verwendet, die (s. Fig.3) mit Streben h versehen sind, welche auf den Latten n aufruhen.Now the butt joints of the stones v lying in a row or belonging to a beam are covered on both sides by short sheets t (Fig. 2), which cling closely to the side surfaces of the stones and which have the shape of a channel with two flat flanges, and which are temporarily held in that the lower flange: 2 is inserted between the lower flange of the stones and the adjacent slat n. After the reinforcements a, b and end plates t have been laid in this way, the end plates t lying opposite one another are spread by means of wedges h driven between them; Since this spreading by wedges is not possible with the sheets t lying on the outer sides of the first and last rows of stones, sheets t are used at these points, which (see Fig. 3) are provided with struts h, which are on the battens n riot.
Nunmehr werden -die Stöße und diie die Obemgurtarmierungen aufnehmenden Rinnen u mit sehr dünnflüssigem Zement ausgegossen, wobei derselbe auch die die Zugarmierungen a aufnehmenden, nach abwärts gekehrten Rillen o der Untergurte erfüllt. Ürn das Einfließen des Zements in die von den LUntergurtrillen o gebildeten Tunnel zu begünstigen, kann der Arbeitsbühne ein leichtes Gefälle gegeben werden.Now the joints and the upper belt reinforcements will be absorbed Gutters u poured with very thin cement, the same also the the Tensile reinforcements a receiving, downward facing grooves o the lower chords met. Ürn the flow of cement into the tunnel formed by the LUntergurtrillen o To favor, the working platform can be given a slight slope.
