Abstract

The moulding system is for production of tubes or pipes, in partic for production of very large heavy pipes of steel reinforced concrete. The outer jacket (2) of the mould consists of steel sheet having a series of reinforcement or strengthening ribs in the form of a separate component. The ribs are in the form of pretensioned cage (8, 9) which is produced from steel profile sections which fits around the outer jacket (2) of the mould. Attachments (10) for vibratory devices (13) are provided. Threaded clamps are used on outer and inner peripheries of the mould jacket to provide accurate size adjustment.

Description

Form zur Herstellung von Rohren Die Erfindung betrifft eine Form zur Herstellung von Rohren, und zwar vorzugsweise von schweren Großrohren aus Stahlbeton. Mold for making pipes The invention relates to a mold for the production of pipes, preferably heavy, large pipes made of reinforced concrete.

Bekannte Formen dieser Art bestehen aus einem Innenmantel, einem Außenmantel mit daran befestigten Rüttlern, einer Untermuffe und einer Obermuffe. In den zwischen Innenmantel und Außenmantel vorhandenen ringförmigen Hohlraum wird zunächst eine Stahlarmierung und anschließende Betonmasse eingebracht, worauf die eingebrachte Betonmasse durch Einschalten der am Außenmantel befestigten Rüttler vernichtet wird.Known forms of this type consist of an inner jacket, an outer jacket with attached vibrators, a lower sleeve and an upper sleeve. In the between Inner jacket and outer jacket existing annular cavity is initially a Steel reinforcement and subsequent concrete mass introduced, whereupon the introduced Concrete mass is destroyed by switching on the vibrator attached to the outer shell.

Um beim Füllen der Form und dem anschließenden Rüttelvorgang unerwünschte Deformierungen des aus Stahlblech gefertigten Außenmantels zu vermeiden und die Rüttler befestigen zu können, muß der Außenmantel durch ein Gerippe od. dgl. verstärkt werden.To be undesirable when filling the mold and the subsequent shaking process To avoid deformations of the outer jacket made of sheet steel and the To be able to attach vibrators, the outer jacket must be reinforced by a framework or the like will.

Da aber für die Serienfertigung von Großrohren stets eine grössere Anzahl von Formen vorhanden sein muß, weil jede Form bis zum Abbinden des Betons, also einige Stunden geschlossen bleiben muß, sind für die Serienfertigung von Großrohren beträchtliche Investitionen erforderlich, wobei die Kosten des durch ein Gerippe versteiften Außenmantels mit den daran befestigten Rüttlern eine erhebliche Rolle spielen.But since there is always a larger one for the series production of large pipes Number of forms must be available, because each form until the concrete has set, So must remain closed for a few hours, are for the series production of large pipes Considerable investment is required, with the cost of going through a skeleton stiffened outer jacket with the attached vibrators play a significant role to play.

Der Erfindung liegt daher die Aufgabe zugrunde, die bei der Großrohrfertigung zu investierenden Formkosten zu senken.The invention is therefore based on the object in large pipe production to reduce mold costs to be invested.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß der aus Stahlblech gefertigte Außenmantel der Form und dessen Versteifungsrippen als getrennte Bauteile ausgebildet sind, wobei das Gerippe die Gestalt eines aus Stahlprofilen gefertigten, auf dem Stahlblechmantel fest spannbaren Käfigs hat, der Befestigungsmittel für Rüttelgeräte aufweist.The solution to this problem is that of the invention Sheet steel made outer shell of the form and its stiffening ribs as separate Components are formed, the framework having the shape of a steel profile manufactured cage that can be firmly clamped on the sheet steel jacket, the fastening means for vibrators.

Bei einer bevorzugten Ausführungsform besteht der Käfig aus mehreren U-förmig profilierten Klemmringen und diese Ringe miteinander verbindenden U-Profilstäben, die die Befestigungsplatten für die Rüttelgeräte tragen.In a preferred embodiment, the cage consists of several U-shaped profiled clamping rings and these rings connecting U-profile rods, which carry the mounting plates for the vibrators.

Durch die erfindungsgemäße getrennte Herstellung von Stahlblech-Außenmantel und Käfig ist die Möglichkeit gegeben, den Käfig unmittelbar nach jedem Rüttelvorgang von der Form abzuziehen, ihn um eine andere Form zu legen, darauf festzuspannen und die in dieser Form befindliche Betonmasse durch Rüttelung zu verdichten.Due to the separate production of sheet steel outer jacket according to the invention and cage is given the opportunity to move the cage immediately after each shaking process peel it off from the mold, put it around another mold, clamp it on it and to compact the concrete mass in this form by vibration.

Auf diese Weise wird für sämtliche bei einer Serienfertigung benötigte Formen nur ein einziger mit Rüttlern ausgestatteter Käfig benötigt und somit eine beträchtliche Material- und Kostenersparnis erzielt.In this way, everything is needed in a series production Forms only a single cage equipped with vibrators is required and thus one considerable material and cost savings achieved.

In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel veransehaulichtO Es zeigen: Fig. 1 eine nach der Erfindung ausgebildete Form zur Herstellung von Großrohren mit aufgespanntem Versteifungskäfig teils in Seitenansicht und teils im Vertikalschnitt, Fig. 2 einen Querschnitt durch die Form und den Käfig nach Fig.1, Fig. 3 eine Ansicht des Verschlusses für den Stahlblech-Außenmantel und den darauf fest spannbaren Käfig.In the drawing, the invention is illustrated using an exemplary embodiment 1 shows a mold designed according to the invention for the production of Large pipes with stretched stiffening cage partly in side view and partly in vertical section, FIG. 2 shows a cross section through the mold and the cage according to FIG. 3 shows a view of the closure for the sheet steel outer jacket and the one thereon firmly clamped cage.

In dem dargestellten Ausführungsbeispiel besteht die Form aus einem aus Stahlblech gefertigten Innenmantel 1, einem ebenfalls aus Stahlblech gefertigten Außenmantel 2, einer Untermuffe 3 und einer Obermuffe 4. Der Innenmantel 1 ist durch drei mit Spreizschlössern 5 versehene U-Profilringe 6 verstärkt.In the illustrated embodiment, the mold consists of a Inner jacket 1 made from sheet steel, one also made from sheet steel Outer jacket 2, a lower sleeve 3 and an upper sleeve 4. The inner jacket 1 is through three with expansion locks 5 provided U-profile rings 6 reinforced.

Der Außenmantel 2 und die Untermuffe 3 stützen sich auf einem Ring 11 ab, unter dem Gummi-Metall-Elemente 12 befestigt sind, mit denen sich die Form elastisch auf dem Boden abstützt.The outer jacket 2 and the lower sleeve 3 are supported on a ring 11 from, under which rubber-metal elements 12 are attached, with which the shape resiliently supported on the floor.

Auf dem Außenmantel 2 ist ein getrennt hergestellter Käfig festklemmbar, der in dem dargestellten Ausführungsbeispiel aus vier in etwa gleichmäßigen Abständen voneinander angeordneten, mit je einem Spannschloß 7 versehenen U-Profilringen 8 und diese Ringe 8 miteinander verbindenden, senkrecht verlaufenden U-Profilstäben 9 besteht. Auf den Profilstäben 9 sind rechteckige Platten 10 festgeschweißt, die zum Befestigen an sich bekannter Rüttelgeräte dienen, von denen in Fig. 2 eines schematisch dargestellt und mit 13 bezeichnet ist.A separately manufactured cage can be clamped onto the outer jacket 2, that in the illustrated embodiment from four approximately equal distances U-profile rings 8 arranged from one another and each provided with a turnbuckle 7 and these rings 8 interconnecting, vertically extending U-profile bars 9 consists. On the profile bars 9 rectangular plates 10 are welded, the serve to attach known vibrators, of which in Fig. 2 one is shown schematically and denoted by 13.
