Description

Verfahren zum Herstellen von Eisenbetonbaukörpern aller Art mit Bewehrung Bei .den bekannten Spannbetonverfahren zur maschinellen Herstellung von hochwertigen Betonhohlkörpern unter Verwendung von Preßbeton werden Bewehrungseinlagen verwendet, wobei die in der Zugzone liegenden Stahleinlagen bis nahe an die Streckgrenze vorgespannt werden, um nach dem Abbinden des Betons und der Entfernung der Spannvorrirhtung durch die vorgespannte Kraft der Stahleinlagen ein Zusammenpressen des Betons zu erzielen. Dieses hohe Vorspannen der Bewehrungseinlagen bis. zur äußersten Streckgrenze zur Herstellung hochdruck- und hochzugfester- Stahlbetonbaukörper ist bei dem maschinellen Verfahren gemäß der Erfindung unter Verwendung der hochwertigen, steifen, gitterartigen Bewehrung nach dem Patent 672 691 nicht erforderlich.Process for the production of reinforced concrete structures of all types with reinforcement In the case of the known prestressed concrete processes for the mechanical production of high-quality Reinforcement inserts are used in hollow concrete bodies using pressed concrete, The steel inserts in the tensile zone are pre-stressed to near the yield point after the concrete has set and the tensioning device has been removed the pre-tensioned force of the steel inserts prevents the concrete from being compressed achieve. This high pretensioning of the reinforcement layers up. to the ultimate yield point for the production of high pressure and high tensile strength reinforced concrete structures is used in the machine Method according to the invention using the high quality, rigid, lattice-like Reinforcement according to patent 672 691 not required.

Bei dem bekannten maschinellen Verfahren zur Herstellung von Betonbaukörpern, die eine gitterartige Bewehrung haben, erfolgt die Baukörperbildung derart, daß die Bewehrung an den Stirnseiten mittels eines daran befestigten Wellenstumpfes drehbar auf einem Fahrgestell gelagert und der Formling ohne jegliche Form fertiggestellt wird. Bei einer anderren Ausführungsart wird die steife Bewehrung in eine geschloss,ene Form zur Baukörperformung eingelegt, wobei die- Form auf ein Fahrgestell aufgelegt ist. Eine Betonverdichtung durch Betonzusammenpressung erfolgt bei beiden Ausführungsarten nicht.In the known mechanical process for the production of concrete structures, which have a lattice-like reinforcement, the structure is formed in such a way that the reinforcement on the end faces by means of a stub shaft attached to it rotatably mounted on a chassis and the molding completed without any shape will. In another embodiment, the rigid reinforcement is converted into a closed one Inserted form for building structure, with the form being placed on a chassis is. A concrete compaction by concrete compression takes place in both types of execution not.

Mit dem Verfahren der, Erfindung sollen nun zug- :und druckfeste- Betonbaukörper aller Art, die eine Bewehrung gemäß Patent 672 69 i haben, mit den verschiedensten Abmessungen in der Breite, Höhe, Länge und den verschieidensten Farmarten mit ein und derselben Formvorrichtung hergestellt werden sowie ein besonders gutes statisches Zusammenwirken der steifen, gitterartigen, hochwertigen Bewehrung mit dem Beton und eine größte Ausnutzung der in der steifen, gitterartigen Bewehrung .enthaltenen statischen Werte erzielt werden.With the method of the invention are now tensile: and pressure-resistant Concrete structures of all types that have reinforcement according to patent 672 69 i, with the various dimensions in width, height, length and the most diverse Farm types can be produced with one and the same molding device as well as a special good static interaction of the stiff, lattice-like, high-quality reinforcement with the concrete and a greatest utilization the one in the stiff, lattice-like Reinforcement .contained static values can be achieved.

Die Ausführung des Verfahrens erfol t mittels einer besonders hierzu ausgebild lt zweiteiligen, verstellbaren Formvorrichttg;., bestehend aus einer fahrbaren Kernform uritl;; einem feststehenden Formgerüst, welches die äußeren Formbleche des Betonkörpers trägt. In diese Form wird der steife, gitterartige Bewehrungskörper eingelegt und zur Vorverdichtung der Beton nach dem bekannten Druckluftverfahren aus. einem über der Baukörper, form befindlichen Betonbehälter in die Form eingeschleudert. Mit der zweiteilig ausge()il Beten Baukörperform ist es möglich, den frisch geformten Betonbaukörper mittels der fahrbaren Kernform .so zu bewegen, daß die äußeren Flächen des Formlings bei dem Aus fahren aus der Formvorrichtung frei werden. Hierdurch wird es möglich, die Betonnachiverdichtung auszuführen, indem der frische Beton des Formlings m einer Abbindekammer unter hohem Druck mittels einer Preßvorrich tung weiter in die steife, gitterartige Bewehrung eingepreßt wird, wobei die Pressung des Betons bis zur Abbindung aufrechterhalten bleibt.The method is carried out by means of a special tool for this purpose trained according to two-part, adjustable molding device;., consisting of a mobile Core form uritl ;; a fixed mold frame, which the outer mold sheets of the concrete body. The rigid, lattice-like reinforcement body is made into this shape inserted and for precompaction of the concrete according to the well-known compressed air method the end. a concrete container located above the building, form thrown into the form. With the two-part prayer structure, it is possible to use the freshly formed Concrete structure by means of the mobile core shape. To move so that the outer surfaces the molding will be released from the molding device when driving off. Through this it becomes possible to carry out the concrete compaction by adding the fresh concrete the molding m a binding chamber under high pressure by means of a Preßvorrich device is further pressed into the stiff, lattice-like reinforcement, the pressure of the concrete is maintained until it sets.

Die Erfindung ist durch beiliegende Zeichnung veranschaulicht, 'und zwar zeigt Abb. i die Baukörperformvorrichtung im Querschnitt. In Abb. 2 ist die Vorrichtung im Längsschnitt dargestellt mit dem darüber angeordneten fahrbaren Betonbehälter und angebautem Druckluftgerät für die Betoneinschleuderung in die Baukörperform.The invention is illustrated by the accompanying drawings, 'and although Fig. i shows the building body molding device in cross section. In Fig. 2 is the Device shown in longitudinal section with the mobile concrete container arranged above it and attached compressed air device for injecting concrete into the building structure.

Die zweiteilige Gestaltung der Formvorrichtung wurde deshalb gewählt, damit bei dem Ausfahren der Kernform die äußeren Flächen des Formlings zur weiteren Bearbeitung des Formlings frei werden.The two-part design of the molding device was therefore chosen so that when the core mold is extended, the outer surfaces of the molding become wider Processing of the molding become free.

Das feststehende Formgerüstal und c, welches die äußeren Formbleche b trägt, besteht aus einem mit dem Fußboden verbundenen Traggerüst, auf welchem die Formbleche b teils auf feststehenden, teils beweglichen Auslegern a1 auswechselbar und verstellbar befestigt sind. Die Auswechselbarkeit und Verstellbarkeit der Formbleche b wurde deshalb vorgesehen, damit mit ein und derselben Formvorrichtung Baukörper aller Art in den verschiedensten Abmessungen hergestellt werden können.The fixed form framework and c, which is the outer form sheets b, consists of a supporting structure connected to the floor on which the shaped sheets b partly on fixed, partly movable brackets a1 exchangeable and adjustable. The interchangeability and adjustability of the shaped sheets b was therefore intended to use one and the same molding device as a building structure of all kinds can be produced in a wide variety of dimensions.

Die fahrbare Kernform besteht aus einem Fahrrahmen f, Wellen g, Tragrahmen h und Winkeleisen i und bildet den tragenden Teil des Formlings. Es wird hier die Verstell- und Auswechselbarkeit der Formbleche dadurch erreicht, daß. die Tragrahmenh, verschiebbar auf den Wellen g gelagert sind sowie durch die Verstellbarkeit der in den Tragrahmen 1t befestigten Tragbolzen I(, auf denen die Formbleche L, m, u gleichfalls verstellbar gelagert sind. Ferner sind die Formbleche o äuf einen im Tragrahmen k geführten Tragbolzenn gelagert, mit welchem durch eine Hebelübertragung p die Formbleche o auf- und abwärts bewegt werden können. Die Formbleche 1, m, u, o und b werden auswechselbar auf Trägern g mittels Flügelschrauben, die in durch die zwei Träger g gebildeten Längsschlitzen r verschiebbar angeordnet sind, gehalten. Zur Herstellung von Rippen im Baukörper werden Formbleche u und auf Tragbolzen s befestigte Formbleche o verwendet.The mobile core mold consists of a driving frame f, shafts g, support frame h and angle iron i and forms the load-bearing part of the molding. The adjustability and interchangeability of the shaped sheets is achieved here in that. the support frames h, are slidably mounted on the shafts g and due to the adjustability of the support bolts I (which are fastened in the support frame 1t and on which the shaped sheets L, m, u are also adjustable stored, with which the shaped sheets o can be moved up and down by means of a lever transmission P. The shaped sheets 1, m, u, o and b are interchangeably arranged on supports g by means of wing screws which are slidable in longitudinal slots r formed by the two supports g To produce ribs in the structure, shaped sheets u and shaped sheets o fastened to support bolts s are used.

Zur Betoneinbringung in die Baukörperform wird ein auf einem feststehenden Trag gerüst fahrbar angeordneter Betonbehälter bekannter Art verwendet, in welchem zur Bewegungdes Gutes ein motorisch angetriebenes Rührwerk t eingebaut ist, welches den Beton durch die in dem Boden des Betonbehälters befindlicheöffnungv hindurchdrückt, wobei der Beton auf das motorisch angetriebene Schaufelrad x fällt, welches dann das Gut beschleu; nigt in dem am Betonbehälter befindlichen Trichter w schleudert. Zur Betonvorverdichtung wird dann durch einen auf dem Fahrgestell des Betonbehälters befestigten Drucklufterzeuger y bekannter Art mittels der durch die' Düse z in den Trichter u, zugeführten Druckluft das in dem Trichter t;' befindliche Gut in die Baukörperform geschleudert und eingepreßt, wobei zur Enriveichung der Druckluft ein Schlitz n1 bekannter Art vorgesehen ist, damit die Druckluft nicht in die Baukörperform hineingeblasen wird (Abb.2).In order to pour concrete into the building form, a fixed Support scaffold mobile arranged concrete container of known type used in which a motor-driven agitator t is installed to move the goods pushes the concrete through the opening v in the bottom of the concrete container, whereby the concrete falls onto the motor-driven paddle wheel x, which then the property accelerates; nigt in the hopper w located on the concrete container. Concrete precompaction is then carried out by a on the chassis of the concrete container attached compressed air generator y known type by means of the 'nozzle z in the Funnel u, supplied compressed air that is in the funnel t; ' good located in the Structure form thrown and pressed in, whereby for Enriveichung the compressed air a slot n1 of a known type is provided so that the compressed air does not enter the structural shape is blown into it (Fig.2).
