Description

Selbstschreitende Stütz- und Gleitschalung zum Einbringen einer Ortbetonaüskleidung Self-advancing support and sliding formwork for installing in-situ concrete outer clothing
Beschreibungdescription
Die Erfindung betrifft eine selbstschreitende Stütz- und Gleitschalung zum Einbringen einer Ortbetonauskleidung der im Oberbegriff des Anspruchs 1 angegebenen Gattung. Eine solche Stütz- und Gleitschalung ist üblicherweise wahlweise in kontinuierlichem, diskontinuierlichem oder absatzweisem Betonierbetrieb einsetzbar.The invention relates to a self-advancing support and sliding formwork for introducing an in-situ concrete lining of the type specified in the preamble of claim 1. Such support and sliding formwork can usually be used optionally in continuous, discontinuous or batch-wise concreting operations.
Bei einer bekannten selbstschreitenden Stütz- und Gleitschalung dieser Gattung (DE 30 43 312 AI) erfolgt deren Vortrieb mit Hilfe des Druckes des Betons, der in den hinter der Stirnschalung befindlichen Teil des Ringraumes eingepreßt wird. Prinzipiell ist die bekannte gattungsgemäße Gleitschalung für einen kontinuierlichen, diskonti¬ nuierlichen oder absatzweisen Betonierbetrieb geeignet. Jedoch reichen selbst beim kontinuierlichen Betonierbetrieb oft, insbesondere bei relativ dünnen Betonwandstärken die Druckkräfte des im Bereich der Stirnschalung eingepumpten Betons nicht aus, um die gesamte Schalung vorwärtsbewegen zu können. Beim diskontinuierlichen oder absatzweisen Betonier¬ betrieb, bei dem die Vorwärtsbewegung der Schalung durch Betonierpausen unterbrochen ist, müssen Zug- oder Druckkräfte zur Verfügung gestellt werden, die sich extern, d.h. außerhalb der Schalung selber, abstützen können.In a known self-advancing support and sliding formwork of this type (DE 30 43 312 AI), their propulsion takes place with the help of the pressure of the concrete which is pressed into the part of the annular space located behind the face formwork. In principle, the known generic formwork is suitable for a continuous, discontinuous or batch-wise concreting operation. However, even in continuous concreting operations, especially with relatively thin concrete wall thicknesses, the compressive forces of the concrete pumped in the area of the face formwork are not sufficient to be able to move the entire formwork forward. In discontinuous or batch-wise concreting operations, in which the forward movement of the formwork is interrupted by concreting breaks, tensile or compressive forces must be made available that are external, i.e. outside of the formwork itself.
Für den absatzweisen Betonierbetrieb, bei dem das Schalen und Betonieren zeitlich nacheinander erfolgt, sind Schalungen bekannt, die aus einklappbaren bzw. absenkbaren Elementen bestehen, die auf einem in Tunnellängsachse verfahrbaren 'Traggerüst aufliegen*. Diese Schalungen haben den Nachteil, daß die hiermit verbundenen Schal- und Einrichtarbeiten sehr zeit- und lohnaufwendig sind.For batch-wise concreting operations, in which the formwork and concreting take place in succession, formworks are known which consist of elements which can be folded or lowered and which rest on a ' supporting frame ' which can be moved along the longitudinal axis of the tunnel * . This formwork has the disadvantage that the associated formwork and set-up work is very time-consuming and costly.
EBSATZBt-ATT Ein weiterer Nachteil besteht darin, daß die Schalung erst dann vom Beton entfernt werden kann, wenn letzterer insgesamt seine geforderte Tragfähigkeit erreicht hat, was zu wirtschaftlich relevanten Wartezeiten führt.EBSATZBt-ATT Another disadvantage is that the formwork can only be removed from the concrete when the latter has reached its required load-bearing capacity, which leads to economically relevant waiting times.
Die Besonderheiten des Stollen- oder Tunnelbaus oder auch eines Kaminbaus erfordern eine Betonschalung, die einerseits kontinuierlich oder diskontinuierlich vorwärtsgleiten kann und die andererseits bei besonderen Erfordernissen ohne Aufwand auf einen absatzweisen Betonierbetrieb umgestellt werden kann, z.B. wenn besondere Bewehrungen in besonders druckbelasteten Streckenabschnitten einzubringen oder Aussparungen für Nischen, Querschläge usw. hergestellt werden sollen.The special features of tunnel or tunnel construction or chimney construction require concrete formwork that can slide forward continuously or discontinuously on the one hand and that on the other hand can be converted to a batching concreting operation without any effort, e.g. if special reinforcements are to be installed in sections of the track that are subject to particularly high pressure or if recesses for niches, cross passages etc. are to be made.
Aufgabe der Erfindung ist es, eine selbstschreitende Stütz- und Gleitschalung der im Oberbegriff des Anspruchs 1 angegebenen Gattung vorzuschlagen, die in Verbindung mit einer freien Wahl zwischen einem kontinuierlichen, dis¬ kontinuierlichen oder absatzweisen Betonierbetrieb das Vortreiben der Schalung in allen drei Betriebsarten unter den üblichen vorkommenden Betriebsbedingungen ermöglicht, ohne daß hierfür zu irgendeiner Zeit eine externe Abstützung der Zug- oder Druckkräfte erforderlich ist, d.h. eine Schalung zu schaffen, die bei allen drei Betriebsarten aus sich selber heraus selbstschreitend ist.The object of the invention is to propose a self-advancing support and sliding formwork of the type specified in the preamble of claim 1, which, in conjunction with a free choice between a continuous, discontinuous or batch-wise concreting operation, drives the formwork in all three operating modes under the usual ones operating conditions occurring without any external support of the tensile or compressive forces is required for this, ie to create formwork that is self-advancing in all three operating modes.
Die erfindungsgemäße Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Anspruchs 1 in Verbindung mit dessen Gattungsmerkmalen.The achievement of this object results from the characterizing features of claim 1 in connection with the generic features.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den ünteransprüchen.Advantageous further developments of the invention result from the subordinate claims.

Die Längsträger 18 ihrerseits sind auf Stützrahmen aufgelagert, von denen in den Fig. 1 und 2 der in Schreitrichtung vorderste Stützrahmen 40 gezeigt ist, während in den Fig. 3, 4 und 6 weitere Stützrahmen 42 und 44 dargestellt sind.REPLACEMENT BLA " * " 1 " Formwork segment 12, 22, 32 four, individual, axially parallel formwork segments 14. Each formwork segment 14 comprises a formwork element in the form of a formwork sheet 16, which is attached to the concrete and which can be inflated via hydraulically actuated transmission elements, which in the embodiment shown in FIG. 5 are hoses 50, is connected to a supporting substructure in the form of a longitudinal beam 18. The longitudinal beams 18 in turn are supported on support frames, of which the frontmost support frame 40 is shown in FIGS. 1 and 2, while further support frames 42 and 44 are shown in FIGS. 3, 4 and 6.
Sämtliche Schalungsbleche 16 aller Schalungssegmentgruppen bilden zusammen eine äußere Schalungshaut des Schalungskörpers 10. Nach Fig. 3 umfaßt die Stütz- und Gleit¬ schalung außerdem eine Stirnschalung 34, die die Vorderseite eines Ringraumes abschließt, der zwischen der Außenwandung des Bauwerkes bzw. einer dort angebrachten Außenschalung, z.B. einer äußeren .Betonschale um den Schalungskörper 10 gebildet ist. Die Stirnschalung 34 ist über eine hydraulisch längenveränderliche Abstützführung 70 an dem in Vortriebs¬ richtung vordersten Stützrahmen 40 abgestützt.All formwork sheets 16 of all formwork segment groups together form an outer formwork skin of the formwork body 10. According to FIG. 3, the supporting and sliding formwork also includes an end formwork 34 which closes the front of an annular space which between the outer wall of the building or an outer formwork attached there , e.g. an outer .Concrete shell around the formwork body 10 is formed. The front formwork 34 is supported on the support frame 40, which is the foremost in the forward direction, by means of a hydraulically variable support guide 70.
Die einzelnen Schalungssegmente 14 sind relativ zu ihren benachbarten Schalungssegmenten längsverschieblich, während jedes Schalungsblech 16 in Bezug auf seinen Längsträger 18 hδhenveränderlich ist. Dichtelemente, die entlang den Längsseiten der Schalungsbleche 16 zwischen diesen angeordnet sind, dichten den vorstehend erwähnten Ringraum ab, d.h. sie verhindern ein Auslaufen von Beton, in das Innere des Schalungskδrpers 16. Das Schalungsblech 16 und der zugeordnete Längsträger 18 jedes Schalungssegmentes 14 sind in Längsrichtung gegeneinander unverschieblich gekoppelt, während die hydraulischen Übertragungsglieder in Form der blähbaren Schläuche 50 bei jedem SchalungssegmentThe individual formwork segments 14 are longitudinally displaceable relative to their adjacent formwork segments, while each formwork sheet 16 is variable in height with respect to its longitudinal beam 18. Sealing elements, which are arranged along the longitudinal sides of the formwork sheets 16 between them, seal the above-mentioned annular space, i.e. they prevent concrete from escaping into the interior of the formwork body 16. The formwork sheet 16 and the associated longitudinal beam 18 of each formwork segment 14 are coupled to one another in the longitudinal direction so as not to be displaceable, while the hydraulic transmission elements in the form of the expandable hoses 50 for each formwork segment
ERSATZBLATT 14 zwischen dem Schalungsblech 16 und dem Längsträger 18 angeordnet sind.ER S ATZBLATT 14 are arranged between the formwork sheet 16 and the longitudinal beam 18.
Je nach Anwendungsfall sind jeweils mehrere Schalungs¬ segmente 14 zu unterschiedlichen Schalungssegment¬ gruppen 12, 22, 32 zusammengefaßt. Dabei sind für jede Gleit¬ schalung ebensoviele Schalungssegmentgruppen 12, 22, 32 vorgesehen, wie Stützrahmen 40, 42, 44 vorhanden sind. Jede der Schalungssegmentgruppen 12, 22, 32 ist mit einem anderen der Stützrahmen 40, 42, 44 fest verbunden und auf den verbleibenden Stützrahmen gleitverschieblich gelagert.Depending on the application, several formwork segments 14 are combined to form different formwork segment groups 12, 22, 32. As many formwork segment groups 12, 22, 32 are provided for each sliding formwork as there are support frames 40, 42, 44. Each of the formwork segment groups 12, 22, 32 is firmly connected to another of the support frames 40, 42, 44 and is slidably mounted on the remaining support frame.
Wie aus den Fig. 3, 4 und 6 ersichtlich ist, sind zwischen den einzelnen Stützrahmen 40, 42, 44 voneinander unabhängig betätigbare Druck-/Schub-Glieder in Form von hydraulischen Pressen 52 angeordnet, mit denen jeder Stützrahme"n 40, 42, 44 für sich gegenüber den verbleibenden Stützrahmen verschiebbar ist.3, 4 and 6 can be seen, between the individual support frames 40, 42, 44 independently operable pressure / push members in the form of hydraulic presses 52 are arranged, with which each support frame " n 40, 42, 44 is slidable relative to the remaining support frame.
Bei den in den Fig. 1 und 2 dargestellten Ausführungs¬ formen sind drei Schalungssegmentgruppen 12, 22, 32 und drei Stützrahmen 40, 42, 44 vorgesehen, wobei bei der darge¬ stellten Ausführungsform jede Schalungssegmentgruppe etwa 1/3 der Schalungshaut bildet. Je nach Anwendungsfall ist es jedoch ohne weiteres möglich, mehr Stützrahmen und Schalungs¬ segmentgruppen vorzusehen und/oder die einzelnen Schalungs¬ segmentgruppen unterschiedlich breit zu wählen, z.B. indem einander benachbarte Schalungssegmente in benachbarten Schalungssegmentgruppen beim einen Anwendungsfall einer Gruppe und beim anderen Anwendungsfall der anderen Gruppe zugeordnet und mit dem Stützrahmen fest verbunden werden, der zur Verschiebung der Gruppe dient. Von Einfluß für diese Wahl sind u.a. die zu erwartenden Reibungskräfte in den jeweiligen Bereichen der Schalungshaut und/oder die Reibungskräfte, die an Schalungssegmenten wirksam sind, wenn diese aus der Ruhestellung vorgeschoben werden sollen.In the embodiments shown in FIGS. 1 and 2, three formwork segment groups 12, 22, 32 and three support frames 40, 42, 44 are provided, with each formwork segment group forming approximately 1/3 of the formwork skin in the embodiment shown. Depending on the application, however, it is easily possible to provide more support frames and formwork segment groups and / or to select the individual formwork segment groups of different widths, e.g. in that adjacent formwork segments in adjacent formwork segment groups are assigned to one group in one application and to the other group in the other application and are firmly connected to the support frame which serves to shift the group. Some of the factors influencing this choice are the expected frictional forces in the respective areas of the formwork skin and / or the frictional forces that are effective on the formwork segments when these are to be advanced from the rest position.

ER In Fig. 6 ist eine zweiteilige Ausbildung einer Gleitschalung in Form einer vorausschreitenden Ausbau¬ schalung 2 und einer gleichartigen Stützschalung 4 dargestellt. Die Schalungssegmente 14 der beiden Schalungen 2 und 4 sind in Längsrichtung miteinander fluchtend angeordnet.HE 6 shows a two-part design of a sliding formwork in the form of a progressive expansion formwork 2 and a similar supporting formwork 4. The formwork segments 14 of the two formworks 2 and 4 are arranged in alignment in the longitudinal direction.
Bei den in den Fig. 5 und 7 gezeigten Ausführungsformen von Schalungssegmenten sind jeweils fünf parallel zueinander angeordnete Gruppen von blähbaren Schläuchen 50 vorgesehen, die auf der Rückseite des zugeordneten Schalungsbleches 16 bzw. 16a in zugeordneten Kammern untergebracht sind, die von Trennstegen 20 bzw. 20a begrenzt sind. Die Trennstege 20 bzw. 20a greifen dabei zwischen und um die Schläuche 50. Die äußeren Trennstege 20a sind dabei verlängert ausgebildet und greifen als seitliche Halteelemente um den zugeordneten Längsträger 18, so daß sie eine Querverschiebung zwischen dem Schalungsblech 16 bzw. 16a und dem Längsträger 18 verhindern.In the embodiments of formwork segments shown in FIGS. 5 and 7, five groups of expandable hoses 50 are provided which are arranged parallel to one another and which are accommodated on the back of the associated formwork sheet 16 or 16a in associated chambers which are separated by separating webs 20 or 20a are limited. The separating webs 20 and 20a engage between and around the hoses 50. The outer dividing webs 20a are of elongated design and engage as lateral holding elements around the associated longitudinal member 18, so that they cause a transverse displacement between the formwork sheet 16 or 16a and the longitudinal member 18 prevent.
Die Gruppen von blähbaren Schläuchen 50 können selber wiederum in einzelne Kammern unterteilt sein. Nach Fig. 5 ist eine Hydrauliksteueranordnung 60 vorgesehen, mit "der in jedem der Schläuche 50 bzw. Schlauchkammern wahlweise ein voreingestellter Druckwert aufrechterhalten werden kann. Hierzu umfaßt die Hydraulikanordnung 60 eine Hydraulikpumpe und für jeden Schlauch 50 bzw. jede Kammer ein zugeordnetes Druckbegrenzungsventil, dessen Öffnungsdruck einstellbar ist,The groups of inflatable tubes 50 can themselves be subdivided into individual chambers. 5, a hydraulic control arrangement 60 is provided, by means of which a preset pressure value can optionally be maintained in each of the hoses 50 or hose chambers. For this purpose, the hydraulic arrangement 60 comprises a hydraulic pump and for each hose 50 or chamber an associated pressure relief valve, the Opening pressure is adjustable,
Bei der in Fig. 7 dargestellten Ausführungsform ist das Schalungsblech 16a durch Zugfedern in eine gegenüber der Schalungshaut radial zurückgezogene Stellung vorgespannt. Weiterhin weist das Schalungsblech 16a auf seiner der Schalungshaut zugewendeten Seite eine elastisch-nachgiebige Abdeckung 17 auf.In the embodiment shown in Fig. 7, the formwork sheet 16a is biased by tension springs in a position radially retracted relative to the formwork skin. Furthermore, the formwork sheet 16a has an elastically flexible cover 17 on its side facing the formwork skin.
ERSATZBLATT Es wird nunmehr die Betriebsweise der .selbstschreitenden Stütz- und Gleitschalung anhand der Fig. 4a, 4b, 4c und 6 näher erläutert.ER SA TZB L ATT The mode of operation of the self-advancing supporting and sliding formwork will now be explained in more detail with reference to FIGS. 4a, 4b, 4c and 6.
Für ein Fortschreiten der Schalung wird ein beliebiger Stützrahmen, in Fig. 4a der mittlere Stützrahmen 42 mit Hilfe der zwischen den Stützrahmen 40, 42, 44 angeordneten Pressen 52 einschließlich der mit diesem Stützrahmen 42 fest verbundenen Schalungssegmentgruppe (die in der Zeichnung nicht im einzelnen dargestellt ist) um eine vorgewählte Schrittlänge x vorgeschoben. Vor Beginn des Vorschiebens werden die blähbaren Schläuche 50 der zugeordneten Schalungs¬ segmentgruppe auf Transport geschaltet, d.h. der in den blähbaren Schläuchen herrschende Druck wird durch zugeordnete Druckbegrenzungsventile und die in der Hydraulik¬ anordnung 60 vorgesehene Hydraulikpumpe auf einem vorgewählten Druckwert gehalten. Somit können die an der Betonwandung anliegenden Schalungsbleche 16 bzw. 16a auf Änderungen im Verlauf der Oberfläche der Betonwandung reagieren, d.h. bei einer Druckerhδhung entsprechend nachgeben bzw. bei einer Druckunterschreitung entsprechend ausgefahren werden. Wenn z.B. die Schalungsbleche 16 einer Schalungssegmentgruppe 12, 22 bzw. 32 beim Vorwandern eine engere Stelle im Beton passieren, dann wird ein Ansteigen des Druckes über die Überdruckventile abgebaut, so daß sich die betroffenen Schalungsbleche 16 bzw. 16a einwärts bewegen können. Droht dagegen der Druck in den blähbaren Schläuchen beim Passieren einer weiter werdenden Stelle abzufallen, so wird er von der Hydraulikpumpe aufrechterhalten und die betroffenen Schalungsbleche 16 bzw. 16a werden radial weiter nach außen geführt.To advance the formwork, an arbitrary support frame, in FIG. 4a the middle support frame 42 with the help of the presses 52 arranged between the support frames 40, 42, 44 including the formwork segment group firmly connected to this support frame 42 (which is not shown in detail in the drawing) is) advanced by a preselected step length x. Before the start of the advancement, the inflatable hoses 50 of the assigned formwork segment group are switched to transport, i.e. the pressure prevailing in the inflatable hoses is kept at a preselected pressure value by means of assigned pressure limiting valves and the hydraulic pump provided in the hydraulic arrangement 60. Thus, the formwork sheets 16 and 16a adjacent to the concrete wall can react to changes in the course of the surface of the concrete wall, i.e. give in if there is an increase in pressure or extend accordingly if the pressure falls below the pressure. If e.g. If the formwork sheets 16 of a formwork segment group 12, 22 or 32 pass a narrower point in the concrete when moving forward, then an increase in the pressure via the pressure relief valves is reduced so that the formwork sheets 16 and 16a concerned can move inwards. If, on the other hand, the pressure in the inflatable hoses threatens to drop as it passes a point that is becoming wider, it is maintained by the hydraulic pump and the formwork sheets 16 and 16a concerned are guided radially further outwards.
Wie in den Fig. 4b und 4c gezeigt ist, werden nachfolgend der hintere Stützrahmen 44 mit seiner zugeordneten Schalungs¬ segmentgruppe und dann der vordere.Stützrahmen 40 mit seiner zugeordneten Schalungssegmentgruppe jeweils um dieAs shown in FIGS. 4b and 4c, the rear support frame 44 with its associated formwork segment group and then the front support frame 40 with its associated formwork segment group are each reduced by
ERSATZBLATT Schrittlänge x vorgeschoben.ER SA TZBLATT Stride length x advanced.
Wenn einer der Stützrahmen 40, 42, 44 mit seiner zugeordneten Schalungssegmentgruppe 12, 22, 32 vorgeschoben wird, stützt er sich über die an ihm angreifenden Pressen an wenigstens einem der anderen Stützrahmen ab, wobei die stationär gehaltenen Stützrahmen ihre Schalungssegment¬ gruppen gegen die Betonwandung gedrückt halten.If one of the support frames 40, 42, 44 with its associated formwork segment group 12, 22, 32 is pushed forward, it is supported on the presses which engage it on at least one of the other support frames, the stationary support frames holding their formwork segment groups against the concrete wall keep pressed down.
Nach Fig. 2 wird die Schalung über nicht näher bezeichnete hydraulische Stützpressen auf einer nicht näher bezeichneten Fahrbahn abgestützt. Auch der" Druck in diesen Stützpressen wird gesteuert, so daß Unebenheiten in der Fahrbahn, sowie Konvergenzen oder Divergenzen der Fahrbahn in Bezug auf die Längsachse der Schalung ausgeglichen werden, indem die betreffenden Stützzylinder entsprechend ein- oder ausgefahren werden.According to FIG. 2, the formwork is supported on an unspecified roadway by hydraulic support presses, which are not specified. The " pressure in these support presses is controlled so that unevenness in the roadway, as well as convergences or divergences of the roadway in relation to the longitudinal axis of the formwork are compensated by the corresponding support cylinders being retracted or extended accordingly.
Nach Fig. 3 wird die Stirnschalung 34 durch nicht bezeichnete Dichtungen entlang dem Umfang des auszubetonierenden Ringraumes abgedichtet. Weiterhin wird die Stirnschalung 34 von einem in einem Druckzylinder längsverschieblichen Druckkolben der hydraulischen Abstützführung 70 geführt. Da die Abstützführung 70 an dem in Fortschreitrichtung vordersten Abstützrahmen 40 fest angebracht ist, kann die relative Lage der Stirnschalung 34 in Bezug auf den ringförmig geschlossenen vordersten Querschnitt der Schalungshaut geführt gehalten werden, unabhängig davon, ob gerade alle Schalungssegmentgruppen zusammen die vordere Ringfläche bilden oder eine oder mehrere der Schalungssegmentgruppen vorgeschoben worden sind. Außerdem ermöglicht es die hydraulische Führung der Stirnschalung 34, den Vorschub des Schalungskδrpers 10 mit seiner Schalungshaut in gewissen Grenzen unabhängig von dem " Einbringen des Betons in den Ringraum zu gestalten.According to FIG. 3, the front formwork 34 is sealed along the circumference of the annular space to be concreted by seals that are not shown. Furthermore, the front formwork 34 is guided by a pressure piston of the hydraulic support guide 70 which is longitudinally displaceable in a pressure cylinder. Since the support guide 70 is firmly attached to the foremost support frame 40 in the advancing direction, the relative position of the front formwork 34 can be kept guided in relation to the annular closed foremost cross section of the formwork skin, regardless of whether all formwork segment groups together form the front ring surface or one or more of the formwork segment groups have been advanced. In addition, the hydraulic guidance of the front formwork 34 allows the formwork body 10 with its formwork skin to be advanced within certain limits independently of the " introduction of the concrete into the annular space.
ERSATZBLATT Wenn die Druckkraft des vor der Stirnschalung eingepumpten Betons im Verhältnis zu den Reibungskräften ausreicht, kann auch die gesamte Schalung wie bei der bekannten gattungsgemäßen Stütz- und Gleitschalung auf einmal vorbewegt werden, ohne daß die zuvor erläuterte Auflösung der Schalungsbewegung in Teilschritte der Schalungsseg entgruppeή erforderlich ist.ER S ATZB L ATT If the compressive force of the concrete pumped in front of the front formwork is sufficient in relation to the frictional forces, the entire formwork can be moved forward at once, as in the known generic supporting and sliding formwork, without the previously described resolution of the formwork movement in sub-steps of the formwork segment being necessary .
Bei einem absatzweisen Betonierbetrieb, d.h. bei einem Betrieb, bei dem das Schalen und Betonieren zeitlich nacheinander ausgeführt werden, können die Schalungsbleche 16 jeder Schalungssegmentgrup'pe 12, 22, 32 vor deren weiteren Vorschub von der Betonwandung abgezogen werden, um einen Reibungseingriff zu verhindern. Die Vorwärtsbewegung der gesamten Stütz- und Gleitschalung kann somit in Teilabschnitten erfolgen, wobei die einzelnen Schalungssegmente bzw. Schalungssegmentgruppen nach dem Vorwandern wieder an die Betonwandung angedrückt werden, um die Reaktionskräfte aufnehmen zu können, die bei dem Vorschub der folgenden Schalungssegmentgruppen auftreten.In a batch concreting, that is, in an operation in which the shuttering and concreting be performed successively in time, the shuttering plates 16 can each Schalungssegmentgrup 'pe 12, 22 are subtracted 32 prior to their further advance of the concrete wall to prevent a frictional engagement. The forward movement of the entire support and sliding formwork can thus take place in partial sections, the individual formwork segments or formwork segment groups being pressed against the concrete wall again after advancing in order to be able to absorb the reaction forces which occur when the following formwork segment groups are advanced.
Die in Fig. 6 gezeigte zweiteilige Ausführung der Stütz- und Gleitschalung ist in solchen Fällen geeignet, wenn der auszuschalende Betonabschnitt insgesamt noch nicht die erforderliche Tragfähigkeit aufweist. In diesem Fall übernimmt die nachschreitende Stützschalung die Aufgabe der Abstützung, bis die erforderliche Tragf higkeit in dem zugeordneten Betonabschnitt erreicht ist.The two-part design of the supporting and sliding formwork shown in FIG. 6 is suitable in such cases when the concrete section to be stripped does not yet have the required load-bearing capacity. In this case, the post-supporting formwork takes on the task of supporting until the required load-bearing capacity is reached in the assigned concrete section.
Wie bereits vorstehend erläutert worden ist, ist die nachschreitende Stützschalung 4 prinzipiell gleich aufgebaut wie die vorschreitende Ausbauschalung 2. Dabei sind natürlich die Schalungssegmentgruppen der Ausbauschalung 2 und der Stützschalung 4 so untereinander ausgewählt, daß sie in Längsrichtung fluchtend hintereinander liegen und miteinander vorschreiten können, so daß keine nachteiligAs has already been explained above, the post-supporting formwork 4 is basically constructed in the same way as the advancing expansion formwork 2. The formwork segment groups of the expansion formwork 2 and the support formwork 4 are of course selected from one another such that they are aligned one behind the other and can advance in the longitudinal direction, so that no disadvantage
ERSATZBLATT großen Lücken zwischen den Schalungssegmentgruppen entstehen. Die Stützschalungssegmente werden vor dem Vorwandern vorteilhafterweise von der Betonwandung abgezogen. Hierzu sind sie bei der in Fig. 7 dargestellten Ausführungsform mit Zugfedern ausgestattet, die das Schalungsblech 16a auf den zugeordneten Längsträger 18 zu vorspannen. Wenn die blähbaren Schläuche 50 auf einen geringeren Druckwert oder drucklos geschaltet werden, werden die Schalungsbleche 16a durch die Zugfedern von der Betonwandung zurückgezogen.REPLACEMENT LEAF there are large gaps between the formwork segment groups. The support formwork segments are advantageously removed from the concrete wall before the forward movement. For this purpose, they are equipped with tension springs in the embodiment shown in FIG. 7, which prestress the formwork sheet 16a on the associated longitudinal beam 18. When the inflatable hoses 50 are switched to a lower pressure value or without pressure, the formwork sheets 16a are pulled back from the concrete wall by the tension springs.
Weiterhin weist bei der in Fig. 7 gezeigten Ausführungsform eines Stützschalungssegmentes das Schalungsblech 16a auf seiner zur Betonwandung hin gerichteten Oberfläche eine Abdeckung 17 aus elastisch-nachgiebigem Material auf, die dafür sorgt, daß das Stützschalungssegment auch in unebenen Bereichen des Betons diesen vollflächig stützt.Furthermore, in the embodiment of a supporting formwork segment shown in FIG. 7, the formwork sheet 16a has a cover 17 made of elastically resilient material on its surface facing the concrete wall, which ensures that the supporting formwork segment supports the entire surface thereof even in uneven areas of the concrete.
Wie der Fachmann weiß, ist es je nach Erhärtungsfortschritt der zu stützenden Betonwandung möglich, die Stützschalungs¬ segmente mit geringerer Breite als die eigentlichen Schalungssegmente auszubilden oder bei einer entsprechenden bereits vorhandenen Tragfähigkeit des Beton nur noch bestimmte Bereiche, wie z.B. die Firstbereiche zu stützen.As the person skilled in the art knows, depending on the progress of the hardening of the concrete wall to be supported, it is possible to design the supporting formwork segments with a smaller width than the actual formwork segments or, given a corresponding existing load-bearing capacity of the concrete, only certain areas, e.g. to support the ridge areas.
Fig. 8 zeigt eine weitere Ausführungsform für eine hydraulische Abstützung der Schalungselement. Nach Fig. 8 ist ein flexibler Schlauch 55 zwischen den einander gegenüberliegenden Flächen des Längsträgers 18 und des Schalungsbleches 16 angeordnet. Die so begrenzte Kammer wird entlang den Längsseiten durch Längsse-itenstege 20a abgeschlossen, die an dem Schalungsblech 16 angebracht sind.Fig. 8 shows a further embodiment for hydraulic support of the formwork element. According to FIG. 8, a flexible hose 55 is arranged between the opposite surfaces of the longitudinal beam 18 and the formwork sheet 16. The chamber delimited in this way is closed off along the longitudinal sides by longitudinal side webs 20a which are attached to the formwork sheet 16.
Der flexible- Schlauch 55 hat nur dichtende Funktion. Den Druck der Hydraulikflüssigkeit nehmen die die Kammer bzw. den Hohlraum umschließenden wände 16, 18 und 20a auf.The flexible hose 55 has only a sealing function. The pressure of the hydraulic fluid is taken up by the walls 16, 18 and 20a enclosing the chamber or the cavity.
