Description

Die vorliegende Erfindung betrifft eine vorfabrizierte, faltbare Moduleinheit, die an den Faltstellen scharnierartige Vorrichtungen aufweist, welche im gefalteten Zustand eine Volumenreduktion der Moduleinheit für die Lagerung und den Transport ermöglichen, wobei Mittel für die mechanische Verriegelung der Moduleinheit vorgesehen sind.The present invention relates to a prefabricated, foldable module unit which has hinge-like devices at the folding points which, in the folded state, enable the module unit to be reduced in volume for storage and transport, means being provided for mechanically locking the module unit.

Gemäss einer französischen Patentanmeldung FR-A-2.170.267 werden Moduleinheiten mit faltbaren Seitenwänden beschrieben. Die zwei vertikalen Seitenwände weisen je drei Faltstellen und je zweimal drei Scharnierpaare (total 24 Scharniere) auf und können nach innen geklappt werden. Dadurch wird eine Höhen- bzw. eine Volumenreduktion für Transport und Lagerung erreicht. Im aufgeklappten Zustand, der mittels eines hydraulischen Hebers erreicht wird, können die nun gestreckten Stirnwände durch einsetzen von Bolzen in übereinander liegenden Bohrungen bis zur endgültigen Fixierung durch bautechnische Massnahmen, z.B. Betonfüllung, provisorisch gesichert werden.
Diese Lösung weist den Nachteil auf, dass durch die grosse Anzahl von Faltstellen beim Aufklappen problematische Unstabilitäten entstehen können. Ferner ist der Aufwand für die vorgesehene Anzahl Faltstellen gross und entsprechend kostenintensiv.According to a French patent application FR-A-2.170.267, module units with foldable side walls are described. The two vertical side walls each have three fold points and two pairs of three hinges each (a total of 24 hinges) and can be folded inwards. This results in a reduction in height or volume for transport and storage. In the unfolded state, which is achieved by means of a hydraulic jack, the now stretched end walls can be provisionally secured by inserting bolts in bores lying one above the other until final fixing by structural measures, such as concrete filling.
This solution has the disadvantage that problematic instabilities can arise due to the large number of fold points when opening. Furthermore, the effort for the intended number of folding points is large and correspondingly cost-intensive.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung mit kleinerem Aufwand für ein Aufzugsschachtmodul zu schaffen, durch deren Anwendung eine Volumenreduktion durch Zusammenklappen mit weniger Faltstellen möglich ist, wobei Scharniere in bestehenden Konstruktionsteilen integriert und in den Wandflächen nicht sichtbar sein sollen.The present invention has for its object to provide a device with less effort for an elevator shaft module, by its use a volume reduction by folding with fewer folds is possible, hinges should be integrated in existing construction parts and should not be visible in the wall surfaces.

Diese Aufgabe wird durch die in den Ansprüchen gekennzeichnete Erfindung gelöst.This task is characterized by that in the claims Invention solved.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass mittels einer einfachen und billigen Vorrichtung vorfabrizierte Aufzugsschachtmodule für die Lagerung und den Transport so zusammengeklappt werden können, dass eines der linearen Masse beispielsweise noch ein Drittel des Wertes im montierten Zustand aufweist und dass die Stabilität und das Aussehen des fertig montierten Modules nicht beeinflusst wird und dass insbesondere die Steifigkeit der Eckenkonstruktion nicht vermindert wird. Ferner ist das Zusammenklappen und das Aufklappen ohne Verwendung von Spezialwerkzeugen möglich und im zusammengeklappten Zustand ist eine Fixierung vorhanden, welche ein unbeabsichtigtes Aufklappen verhindert.The advantages achieved by the invention are essentially to be seen in the fact that, using a simple and inexpensive device, prefabricated elevator shaft modules can be folded up for storage and transport in such a way that one of the linear masses still has, for example, a third of the value in the assembled state and that the stability and appearance of the fully assembled module is not affected and in particular the rigidity of the corner structure is not reduced. Furthermore, folding and unfolding is possible without the use of special tools and in the folded state there is a fixation which prevents unintentional opening.

Die Figur 1 zeigt ein Aufzugsschachtmodul 1, welches im folgenden mit Modul 1 bezeichnet wird, das eine Rückwand 4, Seitenwände 2 und 3, eine Frontwand 5 mit einer Türöffnung 9 sowie einen unteren Winkelrahmen 7 und einen oberen Winkelrahmen 8 aufweist. Die Frontwand 5, die Seitenwände 2 und 3 und die Rückwand 4 sind aus gleichen Einzelelementen 6, welche als symmetrische Abkantprofile ausgebildet sind, zusammengesetzt und mit den Winkelrahmen 7 und 8 zusammengeschweisst.FIG. 1 shows an elevator shaft module 1, which is referred to below as module 1, which has a rear wall 4, side walls 2 and 3, a front wall 5 with a door opening 9 and a lower angle frame 7 and an upper angle frame 8. The front wall 5, the side walls 2 and 3 and the rear wall 4 are composed of the same individual elements 6, which are designed as symmetrical folding profiles, and welded together with the angle frames 7 and 8.

Der untere Winkelrahmen 7 weist Scharnierstellen 10, 12, 14 und 16 auf. Die letzteren zwei sind in der Figur 1 nicht sichtbar. Der obere Winkelrahmen 8 weist die Scharnierstellen 11, 13, 15 und 17 auf.The lower angle frame 7 has hinge points 10, 12, 14 and 16. The latter two are not visible in FIG. 1. The upper angle frame 8 has the hinge points 11, 13, 15 and 17.

Die Figur 2 zeigt das Modul 1 im horizontalen Querschnitt. Es sind in dieser Figur keine neuen Teile sichtbar, jedoch ist die Profilform der Einzelelemente 6 daraus ersichtlich.Figure 2 shows the module 1 in horizontal cross section. No new parts are visible in this figure, but the profile shape of the individual elements 6 can be seen from this.

Die Figur 3 zeigt eine Seitenansicht mit der Seitenwand 2 und den Scharnierstellen 10, 11, 12 und 13. Einzelelemente 6 sind mit 6.1 und 6.2 bezeichnet. Deren eine randseitige Doppelabkantung ist je über den Scharnierstellen 10, 11, 12 und 13 um einige cm zurückgeschnitten. Eine Schwenkachse 15 bzw. 16 verläuft je zwischen den Einzelelementen 6.1 und 6.2.FIG. 3 shows a side view with the side wall 2 and the hinge points 10, 11, 12 and 13. Individual elements 6 are denoted by 6.1 and 6.2. A double bevel on the edge is cut back by a few cm each above the hinge points 10, 11, 12 and 13. A pivot axis 15 or 16 runs between the individual elements 6.1 and 6.2.

Die Figur 4 zeigt das Modul 1 im zusammengeklappten Zustand. Ein Kantholz 18 dient als Zwischenlage zur Aufnahme seitlich einwirkender Kräfte bei Transport und Lagerung.FIG. 4 shows the module 1 in the folded state. A square timber 18 serves as an intermediate layer for absorbing laterally acting forces during transport and storage.

Die Figur 5 zeigt die Einzelheiten der nach Aussen schwenkbaren Scharnierstelle 10. Diese sind identisch mit jenen der Scharnierstellen 11, 14 und 15. Der untere Winkelrahmen 7 weist in der Fortsetzung der Nahtstelle zwischen den speziellen Einzelelementen 6.1 und 6.2 einen durchgehenden Zwischenraum 10.6 auf.FIG. 5 shows the details of the hinge point 10 which can be pivoted outwards. These are identical to those of the Hinge points 11, 14 and 15. In the continuation of the interface between the special individual elements 6.1 and 6.2, the lower angle frame 7 has a continuous space 10.6.

4.1 ist ein kurzer, rechtwinklig mit der Rückwand 4 fest verbundener Modulschenkel. Auf dem horizontalen Schenkel des linken Teils des unteren Winkelrahmens 7 beim Seitenteil 2 ist die eine Hälfte einer Scharnierlasche 10.1 angeschweisst, welche die Form eines Flacheisenprofils aufweist. Die rechte Seite der Scharnierlasche 10.1 ist mittels zwei durchgehenden Bohrungen 10.2 und 10.4 und mittels zwei Schrauben 10.3 und 10.5 mit dem rechten Teil des unteren Winkelrahmens 7 und somit mit dem kurzen Modulschenkel 4.1 verschraubt. 10.7 sind lösbare Schraubverbindungen zwischen den speziellen Einzelelementen 6.1 und 6.2. 10.8 sind unlösbare Verbindungspunkte zu und zwischen den normalen Einzelelementen 6. 10.9 ist eine verschweisste Eckverbindung des unteren Winkelrahmens 7.4.1 is a short module leg that is firmly connected at right angles to the rear wall 4. On the horizontal leg of the left part of the lower angle frame 7 in the side part 2, one half of a hinge bracket 10.1 is welded, which has the shape of a flat iron profile. The right side of the hinge bracket 10.1 is screwed to the right part of the lower angle frame 7 and thus to the short module leg 4.1 by means of two through bores 10.2 and 10.4 and by means of two screws 10.3 and 10.5. 10.7 are detachable screw connections between the special individual elements 6.1 and 6.2. 10.8 are non-detachable connection points to and between the normal individual elements 6. 10.9 is a welded corner connection of the lower angle frame 7.

Die Figur 5a zeigt die nach aussen schwenkbare Scharnierstelle 10 im geöffneten Zustand. Der Öffnungswinkel beträgt ca. 90°. Die Schraubverbindungen 10.7 und die Schraube 10.3 sind gelöst bzw. entfernt. Das Zentrum der Bohrung 10.4 liegt auf der gleichen Ebene wie die kurzen abgekanteten Schenkel der speziellen Einzelelemente 6.1 und 6.2 wodurch beim Öffnen der Scharnierstelle kein Klemmen in der zu öffnenden Nahtstelle möglich ist.FIG. 5a shows the hinge point 10 which can be pivoted outwards in the open state. The opening angle is approx. 90 °. The screw connections 10.7 and the screw 10.3 are loosened or removed. The center of the bore 10.4 is on the same level as the short bent legs of the special individual elements 6.1 and 6.2, which means that when the hinge point is opened, it is not possible to clamp in the seam to be opened.

Die Figur 6 zeigt die Einzelheiten der nach innen schwenkbaren Scharnierstelle 12. Sie befindet sich zwischen dem Seitenteil 2 und einem kurzen Modulschenkel 5.1, welcher rechtwinklig fest mit dem Frontteil 5 verbunden ist. Beim Drehpunkt der Scharnierstelle 12 ist auf dem vertikalen Schenkel des unteren Winkelrahmens 7 ein lösbares Scharnier 12.10 aufgeschraubt. Eine Trennstelle 12.6 des unteren Winkelrahmens 7 verläuft, ausgehend vom Scharniermittelpunkt schräg, in einem Winkel von 45°, nach aussen. Auf dem horizontalen Schenkel des rechten Teils des unteren Winkelrahmens 7 beim Seitenteil 2 ist die eine Hälfte einer Scharnierlasche 12.1 angeschweisst, welche die Form eines Flacheisenprofils aufweist. Die linke Seite der Scharnierlasche 12.1 ist mittels zwei durchgehenden Bohrungen 12.2 und 12.4 und mittels zwei Schrauben 12.3 und 12.5 mit dem linken Teil des unteren Winkelrahmens 7 und somit mit dem kurzen
Modulschenkel 5.1 verschraubt. 12.7 sind lösbare Schraubenverbindungen zwischen den speziellen Einzelelementen 6.1 und 6.2.FIG. 6 shows the details of the hinge point 12 which can be pivoted inwards. It is located between the side part 2 and a short module leg 5.1, which is connected at right angles to the front part 5. At the pivot point of the hinge point 12, a releasable hinge 12.10 is screwed onto the vertical leg of the lower angle frame 7. A separation point 12.6 of the lower angular frame 7, starting from the center of the hinge, runs obliquely at an angle of 45 ° to the outside. On the horizontal leg of the right Part of the lower angular frame 7 in the side part 2 is welded to one half of a hinge bracket 12.1, which has the shape of a flat iron profile. The left side of the hinge bracket 12.1 is by means of two through holes 12.2 and 12.4 and by means of two screws 12.3 and 12.5 with the left part of the lower angle frame 7 and thus with the short
Module leg 5.1 screwed. 12.7 are detachable screw connections between the special individual elements 6.1 and 6.2.

Die Figur 6a zeigt die nach innen schwenkbare Scharnierstelle 12 im geöffneten Zustand. Der Öffnungswinkel beträgt ca. 90°. Die Schraubverbindungen 12.7 wurden gelöst und die Schrauben 12.3 und 12.5 entfernt. Im geöffneten Zustand und bei einem Öffnungswinkel von 90° liegt die Bohrung 12.2 der Scharnierlasche 12.1 genau fluchtend über der Bohrung 12.4 im unteren Winkelrahmen 7. Die wieder eingesetzte Schraube 12.5 fixiert die Anordnung in diesem Zustand.FIG. 6a shows the inwardly pivotable hinge point 12 in the open state. The opening angle is approx. 90 °. The screw connections 12.7 were loosened and the screws 12.3 and 12.5 removed. In the open state and at an opening angle of 90 °, the bore 12.2 of the hinge bracket 12.1 is exactly aligned with the bore 12.4 in the lower angle frame 7. The screw 12.5 that is reinserted fixes the arrangement in this state.

Die vorstehend beschriebene Einrichtung arbeitet wie folgt:The device described above works as follows:

Die Funktion ist im wesentlichen aus den Zeichnungen ersichtlich. Das Modul 1 gemäss Fig. 1,2 und 5 kann, nach lösen der beschriebenen lösbaren Schraubverbindungen an allen Scharnierstellen, so zusammengeklappt werden, dass sich dessen Grundrissquerschnitt zur Form gemäss Fig. 4 verringert. Dadurch reduziert sich das Tiefenmass des Moduls 1 auf ca. einen Drittel gegenüber dem aufgeklappten Zustand, so dass beispielsweise drei solche Module 1 in Längsrichtung nebeneinander auf einer Lastwagenbrücke Platz finden. Die im zusammengeklappten Zustand wieder eingesetzten Schrauben 12.5 an den nach innen schwekbaren Scharnierstellen 12, 13, 16 und 17 sorgen für die nötige Formsteifigkeit in diesem Zustand. Die Kantholzzwischenlage 18 ist als Sicherheit gegen extreme seitliche Krafteinwirkung zu betrachten. Anstelle dessen kann ein Metallbügel eingesetzt werden, welcher in vorhandene, aber nicht gezeigte Bohrungen im oberen Winkelrahmen 8 der Frontwand 5 und der Rückwand 4 eingesteckt würde.The function can be seen essentially from the drawings. The module 1 according to FIGS. 1, 2 and 5 can, after loosening the detachable screw connections described at all hinge points, be folded together in such a way that its cross-sectional shape reduces to the shape according to FIG. 4. As a result, the depth dimension of the module 1 is reduced to approximately one third compared to the opened state, so that, for example, three such modules 1 can be placed next to one another in the longitudinal direction on a truck bridge. The screws 12.5 reinserted in the collapsed state at the hinge points 12, 13, 16 and 17 which can be swiveled inwards ensure the necessary stiffness in this state. The squared liner 18 is to be regarded as security against extreme lateral forces. Instead, a metal bracket can be used, which is in existing, but Bores not shown in the upper angle frame 8 of the front wall 5 and the rear wall 4 would be inserted.

Beim Aufklappen auf der Baustelle und nach dem Verschrauben der Naht- und Scharnierstellen wird die Steifigkeit eines nicht klappbaren Moduls erreicht, nicht zuletzt deshalb weil die Scharnierstellen 10 bis 16 nicht in den Modulecken angeordnet sind. Die Scharniere 12.10 sind Hilfsscharniere und können, falls erforderlich, im montierten Zustand des Moduls 1 weggenommen werden.When opening on the construction site and after the seam and hinge points have been screwed together, the rigidity of a module that cannot be folded is achieved, not least because the hinge points 10 to 16 are not arranged in the module corners. The hinges 12.10 are auxiliary hinges and, if necessary, can be removed when the module 1 is assembled.

Dank der schrägen Trennstelle 12.6 an den Scharnierstellen 12, 13, 16 und 17 ist es möglich im zusammengeklappten Zustand des Moduls 1 eine mechanische Fixierung mit den normal vorhandenen Verbindungsmitteln vorzunehmen, weil ein Teil des unteren Winkelrahmens 7 vom Modulschenkel 5.1 mit der Bohrung 12.4 in die Flucht des eingeklappten Seitenteils ragt und die Bohrung 12.4 dann genau unter der Bohrung 12.3 der Scharnierlasche liegt. So kann dann an allen vier Scharnierstellen 10, 11, 14 und 15 je eine Schraube eingesetzt und durch festziehen das zusammengeklappte Modul 1 in diesem Zustand mechanisch blockiert werden. Das beschriebene Prinzip liesse sich beispielsweise auch für Schalwände und als Klappen- oder Türoffenhaltesicherung anwenden.Thanks to the oblique separation point 12.6 at the hinge points 12, 13, 16 and 17, it is possible in the collapsed state of the module 1 to carry out a mechanical fixation with the normally available connecting means, because part of the lower angle frame 7 from the module leg 5.1 with the bore 12.4 in the Escape of the folded side part protrudes and the hole 12.4 is then exactly below the hole 12.3 of the hinge bracket. A screw can then be inserted at all four hinge points 10, 11, 14 and 15 and the tightened module 1 can be mechanically blocked in this state. The principle described could also be used, for example, for formwork walls and as a flap or door open safety device.
