Abstract

Barrier-plate elements for waste-water control are described in Patents DE 2552516 and DE 3616418 and due to the design have to be constructed with parallel faces and so as to be corrosion-resistant. The design preferably used for these barrier plates consisted of an inner statically determined lattice frame and an outer high-grade-steel plate covering welded completely airtight. Optimum planeness of the barrier-plate surface could not be achieved in this way. The object of the present invention is to produce optimum planeness by filling a vacuum hollow sealing element (1) with concrete between steel formwork arranged with parallel faces while utilising the applied concrete pressure, the entire surface of which hollow sealing element (1) in the finished state, for example in the case of barrier plates (3), consists of high-grade-steel plates, and by forming a vacuum in the hollow sealing element (1) after the concrete has hardened. Here, the high-grade-steel plate surface, due to the external air pressure then occurring, is pressed against the preformed concrete structure and thus optimum planeness is obtained. Furthermore, a method of constructing barrier plates is shown, which due to the design are positively guided, and thus roller guides and the fitting of a slide box according to DE 2552516 can be dispensed with. <IMAGE>

Description

Die Erfindung bezieht sich auf ein vakumisierbares Hohlkörpervergußelement, dessen gesamte Oberfläche im Fertigzustand aus einem dünnwandigen, verformbaren, schweiß- bzw. klebbaren luftundurchlässigen Material besteht, daß zwischen vertikal bzw. unter einem Winkel aufgestellten Schalungsträgern arretiert wird und inbesondere bei einer beispielhaften Nutzung als Wehrplatte in Anlehnung an DE 2552516 und DE 3616418 mit Beton ausgegossen wird, wobei als Oberflächenmaterialien insbesondere bei wasserdruckbeaufschlagten Elementen wie z.B. bei Wehrplatten dünnwandige Edelstahlbleche verwendet werden, die untereinander luftdicht in allen Nahtbereichen verschweißt werden. Desweiteren wird ein Verfahren aufgezeigt, wie ein solches Hohlkörpervergußelement vorzugsweise als Wehrplatte in Anlehnung an die vorgenannten Patente erstellt werden kann, die konstruktionsbedingt zwangsgeführt werden und somit auf Rollenführungen sowie Einbau eines Schieberkastens gemäß DE 2552516 verzichten können.The invention relates to a vacuumable hollow body potting element, the entire surface of which in the finished state consists of a thin-walled, deformable, weldable or adhesive air-impermeable material that is locked between vertical or at an angle formwork girders and in particular in an exemplary use as a weir plate in Based on DE 2552516 and DE 3616418 is poured out with concrete, the surface materials being particularly those of elements subjected to water pressure, such as, for example thin-walled stainless steel sheets are used for weir plates, which are welded airtight to each other in all seam areas. Furthermore, a method is shown how such a hollow body potting element can preferably be created as a weir plate based on the aforementioned patents, which are constrained by design and thus can dispense with roller guides and installation of a slide box according to DE 2552516.

Die derzeitig hergestellten Wehrplatten wurden vorzugsweise in Stahlfachwerkkonstruktion mit oberflächig aufgeschweißten Edelstahlblechverkleidungen ausgeführt und konnten nur mittels angeformter Rollenführungen und zusätzlichem Einbau eines Schieberkastens zur Sicherstellung der Seitenführung vertikal verfahren werden.The weir plates currently manufactured were preferably constructed in steel framework construction with stainless steel sheet claddings welded onto the surface and could only be moved vertically by means of molded roller guides and the additional installation of a slide box to ensure the lateral guidance.

Ein wesentlicher Nachteil dieser Konstruktionstechnik ist, daß eine Ausbeulung der Bleche innerhalb der Flächen des starren Fachwerkrahmens nur schwerlich auszuschalten ist. Die weitere Verkleinerung der Ausfachung führt letztendlich nicht zur notwendigen Ebenflächigkeit der Gesamtwehrplatte wegen des auftretenden nur bedingt kalkulierbaren Schweißverzuges der Gesamtkonstruktion.A major disadvantage of this construction technique is that a bulge of the sheets within the surfaces of the rigid framework is difficult to switch off. The further reduction of the infill ultimately does not lead to the necessary flatness of the entire weir plate because of the welding distortion of the overall construction that can only be calculated to a limited extent.

Eine ordnungsgemäße Wehrführung und Minimierung der Verschleißeigenschaften im Dichtungsbereich ist nach den gewonnenen Erkentnissen nur mit einer optimalen Ebenflächigkeit und Planparallelität der Wehrplatte zu erreichen.Proper weir management and minimization of wear properties in the sealing area can only be achieved based on the knowledge obtained with an optimal flatness and plane parallelism of the weir plate.

Die vorliegende Erfindung hat es sich zur Aufgabe gemacht, die vorgenannten Nachteile auszuschalten und erfindungsgemäß dadurch zu verbessern, daß ein vakumisierbares Hohlkörpervergußelement, dessen gesamte Oberfläche im Fertigzustand aus einem dünnwandigen, verformbaren, schweiß- bzw. klebbaren luftundurchlässigen Material besteht, und zwischen vertikal bzw. unter einem Winkel aufgestellten Schalungsträgern arretiert wird und inbesondere bei einer beispielhaften Nutzung als Wehrplatte in Anlehnung an DE 2552516 und DE 3616418 mit Beton ausgegossen wird, wobei als Oberflächenmaterialien insbesondere bei wasserdruckbeaufschlagten Elementen wie z.B. bei Wehrplatten dünnwandige Edelstahlbleche verwendet werden, die untereinander luftdicht in allen Nahthereichen verschweißt werden.The present invention has set itself the task of eliminating the abovementioned disadvantages and improving it according to the invention in that a vacuum-encapsulating hollow body casting element, the entire surface of which in the finished state consists of a thin-walled, deformable, weldable or adhesive air-impermeable material, and between vertical or formwork girders set up at an angle are locked and, in particular when used as a weir plate, is poured out with concrete in accordance with DE 2552516 and DE 3616418, thin-walled stainless steel sheets being used as surface materials, in particular for elements pressurized with water, such as weir plates, which are airtight among themselves in all seam areas be welded.

Durch den beim Betoniervorgang auftretenden Betoninnendruck, der im Regelfall zumindest einer 5 m Betonsäule entsprechenden Druckbeaufschlagung erreichen sollte, wird das komplette, vorzugsweise dünnwandige Hohlkörpervergußelement auf die Schalfläche des jeweiligen Schalungsträgers flächenartig aufgepresst. Die vorgenannte Druckbeaufschlagung ist außerordentlich wichtig, damit die insbesondere bei Edelstahlblechkonstruktionen oberflächig auftretenden Verzugsspannungen nicht gewölbeartig nach innen ausbeulen können. Nach Aushärtung des Betons und dem Verschließen der Betonzulauf- bzw. Betonauslauföffnungen wird eine Dichtigkeitsprüfung vorzugsweise unter Druckbeaufschlagung des Hohlkörpervergußelementes insbesondere deren Schweißnähte durchgeführt. Sollten Undichtigkeiten auftreteten so wird die entsprechende Schadstelle nachgeschweißt. Nach erfolgreicher Dichtigkeitsprüpfung einer beispielhaft nach diesem Verfahren erstellten aufbetonierten Wehrplatte wird diese mittels eines eingeschraubten Vakuumventils unter Zuhilfenahme einer noch anzuschließenden Vakuumanlage solange vakumisiert, bis die in diesem Falle dünnwandigen Edelstahlbleche sich infolge des äußeren Luftdruckes auf die durch den Betoniervorgang letztendlich planparallelen Betonkörper aufgepreßt haben.As a result of the internal concrete pressure that occurs during the concreting process, which should normally reach at least one pressurization corresponding to at least 5 m of concrete column, the complete, preferably thin-walled, hollow body casting element is pressed onto the formwork surface of the respective formwork beam. The aforementioned pressurization is extremely important so that the distortion stresses that appear on the surface, particularly in the case of stainless steel sheet constructions, cannot bulge outward in a vault-like manner. After the concrete has hardened and the concrete inlet or outlet openings have been closed, a leak test is carried out, preferably under pressure, on the hollow body casting element, in particular its weld seams. If there are any leaks, the corresponding damaged area is re-welded. After a leak test has been successfully carried out on a concrete weir plate that has been created using this method, it is vacuumed by means of a screwed-in vacuum valve with the help of a vacuum system that is still to be connected until the thin-walled stainless steel plates in this case have been pressed onto the concrete bodies that are ultimately plane-parallel due to the concreting process.

Dieses Verfahren erlaubt somit die Herstellung von planparallelen Wehrplatten in bisher noch nicht erreichbarer Qualität und kontrollierbarer Standsicherheit, weil eventuelle Undichtigkeiten z.B. von Wehrplatten durch die dann auftretende Ausbeulung der Edelstahlblechoberfläche ersichtlich würden.This process thus enables the production of plane-parallel weir plates in previously unattainable quality and controllable stability, because possible leaks, for example, of weir plates through the then bulging of the stainless steel sheet surface would be apparent.

Ein weiterer Vorteil dieser Erfindung ist die konstruktiv bedingte Zwangsführung der Wehrplatte, so daß auf die sonst notwendigen Rollenführungen sowie auf einen Einbau eines Schieberkastens gemäß DE 2552516 verzichtet werden kann.Another advantage of this invention is the design-related forced guidance of the weir plate, so that the otherwise necessary roller guides and the installation of a slide box according to DE 2552516 can be dispensed with.

Ein weiteres Merkmal dieser Erfindung ist die Möglichkeit auch andersartig geformte Hohlkörpervergußelemente z.B. zur Erstellung von architektonischen Raumkörpern, die zwischen entsprechend vorgeformten Schalungsträgern angeordnet und aufbetoiniert oder mit sonstigen flüssigen Vergußmitteln aufgefüllt werden, zu erstellen und nach entsprechender Aushärtung zu vakuumisieren.Another feature of this invention is the possibility of differently shaped hollow casting elements, e.g. for the creation of architectural spatial objects, which are arranged between appropriately preformed formwork beams and cast on concrete or filled with other liquid casting agents, and vacuumed after appropriate hardening.

In den Zeichnungen wird insbesondere ein Ausführungsbeispiel und ein Verfahren zur Herstellung einer Wehrplatte nach dieser Erfindung erläutert.In the drawings, an exemplary embodiment and a method for producing a weir plate according to this invention are explained in particular.

Es zeigt Fig. 1 eine isometrische Darstellung des Hohlkörpervergußelementes [1] in der Ausbildung als Wehrplatte [3], die im Zulaufbereich [4] aus dem U-förmigen Hohlkörperprofil [5] und im Ablaufbereich [6] aus dem Hohlkörperprofil [7] besteht, das seitliche Bördelkanten [8] aufweist, die bis in die Holmbereiche [15] fortgeführt werden.1 shows an isometric representation of the hollow body casting element [1] in the form of a weir plate [3], which consists of the U-shaped hollow body profile [5] in the inlet area [4] and the hollow body profile [7] in the outlet area [6] , which has lateral flanged edges [8] which continue into the spar areas [15].

Die innerhalb der Wehrplatte dargestellten gestrichelten Linien [20] stellen Hilfslinien dar, damit die Mittelpunkte der Zulaufbereiche [4] und des Ablaufbereiches [7] besser verdeutlicht werden. Die notwendigen Lochschweißungen [13] sind aus Übersichtlichkeitsgründen nur in Teilbereichen dargestellt, obwohl diese innerhalb der gesamten Bördelkante [8] anzuordnen sind.The dashed lines [20] shown within the weir plate represent auxiliary lines, so that the centers of the inlet areas [4] and the outlet area [7] are better be made clear. The necessary hole welds [13] are only shown in partial areas for reasons of clarity, although these are to be arranged within the entire flanged edge [8].

Weiterhin ist ersichtlich, daß gemäß Patentanspruch 4 zumindest eine Oberseite des Holmbereiches [15] des Hohlkörpervergußelementes [1] mit einer Holmabschlußplatte [18] versehen ist, in die nach Beendigung und Aushärtung der Vergußmasse ein Ventil [19] adaptiert ist, das je nach Aufschraubrichtung zur Druckbeaufschlagung bzw. zur eigentlichen Vakuumisierung herangezogen werden kann.Furthermore, it can be seen that, according to claim 4, at least one upper side of the spar area [15] of the hollow body potting element [1] is provided with a spar end plate [18], into which a valve [19] is adapted after completion and hardening of the potting compound, depending on the screwing direction can be used for pressurization or for the actual vacuumization.

Entsprechend Patentanspruch 5 ist die Anordnung der Gewindeankerhülsen [23] zu Montagezwecken innerhalb des Überlaufkantenbereiches [21] bzw. im Sohlbereich [22] ersichtlich. Gemäß Patentanspruch 6 ist die sinnvolle Anordnung der in den U-förmigen Schenkeln des Hohlkörperprofiles [5] beidseitig luftdicht zu verschweißenden und im Beton zu verankernden Tragebolzen [24] zur Adaptierung der notwendigen vornehmlich hydraulischen Hubzylinder dargestellt.According to claim 5, the arrangement of the threaded anchor sleeves [23] for assembly purposes within the overflow edge area [21] or in the bottom area [22] can be seen. According to claim 6, the sensible arrangement of the support bolts [24] to be welded airtight on both sides in the U-shaped legs of the hollow body profile [5] and to be anchored in the concrete is shown for adapting the necessary primarily hydraulic lifting cylinders.

Fig. 2 zeigt die Schnittdarstellung 'B-B' der Wehrplatte [3] aus Fig.1 einschließlich Darstellung der Schalungsträger [2] auf denen im Ablaufbereich [6] zwischen den Bördelkanten [8] die Aussparungskörper [17] arretiert sind.Fig. 2 shows the sectional view 'B-B' of the weir plate [3] from Fig.1 including the formwork support [2] on which the recess bodies [17] are locked in the drainage area [6] between the flanged edges [8].

Fig. 3 zeigt eine Detaildarstellung im Schnitt 'A-A' dar, bei dem ersichtlich wird, daß im Endzustand die Zwangsführung der Wehrplatte [3] durch die Anordnung einer gegenüber DE 2552516 verbreiterten Wehrführungskante [14] erreicht wird, die bekannterweise im Führungsrahmen gemäß vorgenanntem Patent angeordnet ist.Fig. 3 shows a detailed view in section 'AA', in which it can be seen that in the final state, the positive guidance of Weir plate [3] is achieved by arranging a weir guide edge [14] widened compared to DE 2552516, which is known to be arranged in the guide frame according to the aforementioned patent.
