Description

The invention relates to a device and a method for the one-piece production of a room module having three side elements and a floor element and / or a ceiling element.

From the DE 10 2008 045 394 A1 an industrially prefabricated room cell for a building with a modular design is known. This room cell has at least two adjoining walls and a floor element connected to them. With such room cells it is still necessary to produce the individual walls and the floor element separately and then to connect them to one another.

Furthermore, from the EP 1 207 238 A2 a prefabricated transportable room cell known, which consists of a base plate, a ceiling plate and side walls in a monolithic composite. However, these individual side walls, the base plate and the top plate are produced separately and connected to one another to form the room cell, for example via grooves and tongues. Different devices are necessary for the production of such side walls, floor panels and ceiling panels so that they can finally be joined together to form a corresponding room cell.

From the FR 2 031 378 A1 a formwork device for the construction of concrete structures is known. The formwork device has two end elements and a central element.

From the DE 26 01 287 A1 a system and a method for the production of concrete room cells is known, which consist of three walls and two plates, the floor and the ceiling. The system consists of two tiltable, heated outer formwork sets and a mold core which can be moved in two directions between these outer formwork sets and is arranged coaxially between these two outer formwork sets. Each set of external formwork consists of the floor formwork, which is attached to a platform, the tiltable side wall formwork and a removable heat shield, which is provided with a calibration frame. The mold core consists of one in two directions movable metal frame, consisting of a carrier that can be rolled in these two directions and a sliding set of internal formwork that is attached to the metal frame.

It is therefore the object of the invention to provide an improved device and an improved method for the one-piece production of a three-sided element as well as a floor element and / or a ceiling element having room module.

According to the device, this object is achieved by a device with all the features of claim 1. In terms of method, this object is achieved by a method with all of the features of claim 9. Advantageous embodiments of the invention can be found in the subclaims.

1. a) Ein rechteckiges, aus ersten und zweiten Flächenelementen bestehendes Kopfelement;
2. b) senkrecht zu dem Kopfelement in dessen Randbereichen angeordnete, aus dritten und vierten Flächenelementen bestehende Seitenelemente, wobei wenigstens die dritten oder die vierten Flächenelemente Eckbereiche der Seitenelemente aufweisen;
3. c) die ersten Flächenelemente unter die zweiten Flächenelemente des Kopfelementes absenkbar sowie gegeneinander verschiebbar sind und nachfolgend die zweiten Flächenelemente unter Verringerung der Rechteckfläche des Kopfelementes zusammenschiebbar sind und
4. d) die senkrecht zu dem Kopfelement angeordneten dritten und vierten Flächenelemente der Seitenelemente nacheinander in Richtung einer Mittellängsachse des Kopfelementes beziehungsweise der Kernschalung verfahrbar sind.

The device according to the invention for the one-piece production of a room module having three side elements and a floor element and / or a ceiling element, the device being designed as a crater-shaped and hollow core formwork around which an outer formwork for the room module to be produced can be arranged, has the following features:

1. a) A rectangular head element consisting of first and second surface elements;
2. b) side elements consisting of third and fourth surface elements arranged perpendicular to the head element in its edge regions, wherein at least the third or fourth surface elements have corner regions of the side elements;
3. c) the first surface elements can be lowered below the second surface elements of the head element and can be displaced relative to one another and subsequently the second surface elements can be pushed together while reducing the rectangular area of the head element, and
4. d) the third and fourth surface elements of the side elements, which are arranged perpendicular to the head element, can be displaced one after the other in the direction of a central longitudinal axis of the head element or the core formwork are.

The invention now provides a core formwork around which an outer formwork can be arranged, with reinforcement made of a metal, in particular steel, optionally also being able to be arranged between the core formwork and the outer formwork, so that a hardenable compound is inserted between the outer formwork and the core formwork and the one-piece room module is formed between the outer formwork and the core formwork.

Particularly in the production of garages, it has proven to be useful to use concrete as the hardenable mass, so that one-piece garage modules can be easily produced as room modules with the device according to the invention, which already have a ceiling and a floor panel and three side walls. A garage door can then finally be arranged in the opening there on the open wall of such a garage module. However, it is also possible to produce such room modules with only three side walls and a floor or ceiling plate so that they can be placed on top of one another and a ceiling plate of a lower room module functions as the floor plate of an upper room module or a floor plate of an upper room module functions as a ceiling plate of a lower room module.

As soon as the hardenable mass introduced between the outer formwork and the core formwork, in particular the concrete, has hardened, the outer formwork can be removed.

The fundamental problem that then exists and is solved according to the invention is that the core formwork has to be removed from the cuboid, cured room module. For this purpose, the first surface elements of the head element of the core formwork are first moved under the second surface elements of the head element of the core formwork and then moved against one another in such a way that they move away from the edge of the head element of the core formwork towards its center. Subsequently, the second surface elements of the head element of the core formwork can also be moved against one another, so that the rectangular area of the head element is reduced. In this state, the side elements of the core formwork consisting of third and fourth surface elements are no longer in contact with the edge area of the head element, since its second surface elements are now below Reduction of the rectangular area of the head element are shifted inward. In this respect, there is now a gap between the side elements of the core formwork and its head element with a reduced rectangular area. This gap makes it possible to move the third and fourth surface elements of the side elements one after the other in the direction of the central longitudinal axis of the head element or the core formwork. The gap then no longer exists between the side elements and the head element of the core formwork, but between the side elements of the core formwork and the side elements or the floor element and / or the ceiling element of the room module to be produced. Because the first and second surface elements of the head element have already been moved, the head element is still in contact with the room module, but has already been detached from it. In this state, the core formwork is no longer in contact with the produced room module, so that the core formwork can be easily removed from the produced room module.

1. a) Bereitstellen einer quaderförmigen und hohlen Kernschalung in einer vertikalen Position, in welcher ein rechteckiges Kopfelement die obere Begrenzung der Kernschalung bildet, auf dessen Randbereichen Seitenelemente angeordnet sind,
2. b) Anordnen einer Außenschalung um die quaderförmige und hohle Kernschalung unter Bildung eines Zwischenraums zwischen Außenschalung und Kernschalung,
3. c) Befüllen des Zwischenraums mit einer aushärtbaren Masse,
4. d) Aushärten der Masse,
5. e) Entfernen der Außenschalung,
6. f) Absenken von ersten Flächenelementen unter zweite Flächenelementen des Kopfelementes sowie Verschieben der ersten Flächenelemente gegeneinander in Richtung Mitte des Kopfelementes sowie Zusammenschieben der zweiten Flächenelemente unter Verringerung der Rechteckfläche des Kopfelementes,
7. g) Verfahren von senkrecht zu dem Kopfelement angeordneten dritten und vierten Flächenelementen in Richtung einer Mittellängsachse des Kopfelementes beziehungsweise der Kernschalung und
8. h) Entfernen der Kernschalung aus dem fertigen Raummodul mittels einer Verfahreinrichtung.

The method according to the invention for the one-piece production of a room module having three side elements and a floor element and / or a ceiling element has the following method steps:

1. a) providing a cuboid and hollow core formwork in a vertical position, in which a rectangular head element forms the upper boundary of the core formwork, on the edge areas of which side elements are arranged,
2. b) arranging an outer formwork around the cuboid and hollow core formwork with the formation of a space between the outer formwork and the core formwork,
3. c) filling the space with a hardenable compound,
4. d) hardening of the mass,
5. e) removing the outer formwork,
6. f) lowering of first surface elements below second surface elements of the head element and moving the first surface elements against each other in Towards the middle of the head element as well as pushing the second surface elements together while reducing the rectangular area of the head element,
7. g) moving third and fourth surface elements arranged perpendicular to the head element in the direction of a central longitudinal axis of the head element or the core formwork and
8. h) Removal of the core formwork from the finished room module by means of a moving device.

By means of the device according to the invention and the method according to the invention, it is now possible to manufacture one-piece room modules, in particular one-piece garage modules that only need to be provided with a corresponding garage door. A separate connection of the individual side walls or the floor and ceiling panels to the side walls is no longer necessary, since these are already connected to one another in one piece with the device and the method according to the invention.

According to the method according to the invention, it can be provided that installation elements, such as electrical lines, fresh water and waste water pipes, heating pipes and other sanitary facilities, free spaces for windows and doors, empty pipes and the like are arranged on the core formwork before an outer formwork is arranged. This has the particular advantage that such installation elements no longer have to be arranged subsequently in the room module, which usually also leads to damage to the individual walls or ceiling and / or floor panels.

In particular when using concrete as the hardenable mass, it has proven to be advantageous that reinforcement is attached to the core formwork before an outer formwork is arranged. In the case of reinforcement of this type using concrete as the hardenable compound, metal reinforcement, in particular steel reinforcement, is generally recommended.

According to a first advantageous embodiment of the device according to the invention, it is provided that a moving device is provided within the hollow core formwork, with which the surface elements can be moved. This measure makes it possible in a simple manner to provide such a moving device for the individual surface elements and to arrange it within the cavity of the core formwork, which is otherwise not used or where a device for stabilizing the core formwork must otherwise be provided. Such a moving device therefore not only serves to remove the corresponding surface elements from the space module after it has hardened. Rather, such a moving device also provides a stabilization element that holds the surface elements during the hardening of the hardenable mass, in particular the concrete, in the corresponding position against the pressure of the not yet hardened mass until the mass hardens.

It has furthermore proven to be advantageous that the displacement device is designed for the mechanical, electrical, pneumatic and / or hydraulic displacement of the surface elements. Such moving devices are known in many ways and can be easily integrated into the cuboid, hollow core formwork, so that they guarantee both the stability function during the hardening of the hardenable mass and the subsequent necessary movement of the individual surface elements, for example via a corresponding lever mechanism.

According to a further advantageous embodiment of the invention, it has been proven that the first surface elements of the head element are designed as diagonal struts extending from its center to its corners. Such diagonal struts can be easily lowered under the second surface elements of the head element and moved against each other so that a corresponding gap is already formed between these diagonal struts and the side elements of the core formwork in the corner areas of the head element. It is then possible in a simple manner to move the other surface elements of the head element against one another while reducing the rectangular area of the head element, so that a circumferential gap is now formed between the head element and the side elements of the core formwork.

It is also advantageous that a rotary element designed as a head plate is provided for lowering the first surface elements under the second surface elements of the head element, and a guide system is provided for moving them against one another. A Such a guide system can be formed, for example, from bolts arranged on the first surface elements of the head element with corresponding guide rails for these bolts within the core formwork.

When using diagonal struts as the first surface elements of the head element, it is furthermore advantageous that the second surface elements are designed essentially as triangular elements and can be pushed together while reducing the rectangular area of the head element.

However, it is also conceivable to design the first and second surface elements differently, for example the first surface elements can be configured as four cross-shaped struts that extend outward from the center of the head element, and the second surface elements can be arranged as rectangular elements arranged accordingly.

So that the now hardened room module, in particular the finished garage module, can be separated from the core formwork, a tilting device is provided with which the core formwork can be tilted from a vertical to a horizontal position and vice versa. If the cured room module, in particular the finished garage module and thus also the core formwork, is now in the horizontal position, a moving device is provided with which the room module can be moved away from the core formwork or with which the core formwork can be pulled out of the room module.

The one-piece room module produced and the core formwork are now separated from one another, so that the finished room module can be used for further use, while the core formwork can be reused for the further production of such one-piece room modules.

Further goals, advantages, features and possible applications of the present invention emerge from the following description of exemplary embodiments with reference to the drawings.

schematic representation of the production of a room module with a device according to the invention and a method according to the invention in different sub-steps.

In the Figures 1 to 4 an embodiment of a device according to the invention for the one-piece production of a three side elements 24 as well as a floor element 25 and a ceiling element 26 having room module 8 is shown. The room module 8 has not been shown in order to be able to better show the mode of operation of the device according to the invention.

An embodiment of a manufacturing method for a room module with a device according to the invention, for example the device of Figures 1 to 4 , and a method according to the invention is schematically shown in FIG Figures 7 to 13 shown.

From the Figure 1 it can be seen that the device according to the invention is designed as a cuboid and hollow core formwork 10, around which an outer formwork, not shown here, which is in the Figure 9 is provided with the reference numeral 9, can be arranged for the space module 8 to be produced. The core formwork 10 has a rectangular head element 11 consisting of first surface elements 1 and second surface elements 2. In the present embodiment, two first surface elements 1 are provided, which are designed as diagonal struts 27, which run from the center 18 of the head element 11 to two corners 19 of the head element 11 and are angled essentially at right angles in the area of the corners 19. The corresponding second surface elements 2 are designed as triangular elements 7 in this embodiment, so that the second surface elements 2 designed as triangular elements 7 together with the first surface elements 1 designed as diagonal struts 27 form the rectangular head element 11 according to the Figure 1 form.

Side elements 12, 13, 14 and 15 consisting of third surface elements 3 and fourth surface elements 4 are arranged perpendicular to the head element 11 in its edge regions, with the third surface elements 3 having corner regions 17 of the side elements 12, 13, 14 and 15 in the present exemplary embodiment and in the The area of the corners 19 of the first surface elements 1 designed as diagonal struts 27 are essentially flush with their areas angled at right angles.

According to the invention, it is now provided that the first surface elements 1 of the head element 11, designed as diagonal struts 27, can be lowered below the second surface elements 2 of the head element 11, designed as triangular elements 7, as shown in FIG Figure 2 is indicated by the hatching of the first surface elements 1 designed as diagonal struts 27. During or after the lowering of the first surface elements 1, designed as diagonal struts 27, they are shifted relative to one another, so that the corners 19 of the head element 11 are shifted inward towards the center 18 of the head element 11, as shown in FIG Figure 2 is indicated by the arrows within the first surface elements 1. The first surface elements 1 designed as diagonal struts 27 are included Can be moved via a hydraulic moving device and a lever mechanism coupled therewith in the direction of a head plate 5, designed as a rotating device 6, in the center 18 of the head element 11.

To lower the diagonal struts 27, these have bolts 28 which are guided in corresponding guide rails 29 of a guide system 23, as exemplified in FIG Figures 5 and 6th is shown.

After the diagonal struts 27 and thus the first surface elements 1 of the head element 11 have been lowered, the second surface elements 2 of the head element 11, which are designed as triangular elements 7, can also be moved in the direction of a central longitudinal axis 16 of the core formwork 10, as indicated by the arrows on the triangular elements 7 of Figure 2 is indicated.

In Figure 3 A third position of the core formwork 10 according to the invention is now shown, in which the second surface elements 2 designed as triangular elements 7 are moved in the direction of the central longitudinal axis 16 of the core formwork 10. This has the effect that the rectangular area of the head element 11 has been reduced and a gap 20 is formed between the edge regions of the head element 11 and the side surfaces 12, 13, 14 and 15 of the core formwork 10.

This gap 20 makes it possible to move the third surface areas 3 of the core formwork, which are designed as corner areas 17, over their entire longitudinal extent, which also extends over the longitudinal extent of the core formwork 10, also in the direction of the central longitudinal axis 16 of the core formwork 10. This method of the third surface elements 3 designed as corner regions 17 is now shown in FIG Figure 4 shown, this method being indicated by the arrows drawn at the corner regions 17.

Finally, the fourth surface elements 4 can also be moved in the direction of the central longitudinal axis 16 of the core formwork 10, so that the third and fourth surface elements 3 and 4 also adapt to the reduced rectangular area of the head element 11 of the core formwork 10.

In the Figures 5 and 6th is, as already indicated above, in a partial sectional view the inner workings of the core formwork 10 are shown. A lever mechanism, which is not shown in detail here, is visible here, which is designed to move the individual surface elements 1, 2, 3 and 4 accordingly with the aid of the hydraulic movement device, which is also not shown in detail. Furthermore, the hydraulic moving device also ensures that the core formwork 10 withstands the pressure of a curable mass when it hardens and thus ensures the stability of the core formwork 10 and finally an effective and uniform, repeatable production of a large number of identical room modules 8.

In the Figures 7 to 14 the production of a room module 8 in a device according to the invention designed as a core formwork 10 with a method according to the invention is shown schematically. In Figure 7 the core formwork 10 is positioned vertically so that the head element 11 points upwards and the side elements 13 and 15 of the core formwork 10 are tightened in this sectional view. The room module 8 to be produced here should be designed as a garage module with a floor element 25, a ceiling element 26 and three side elements 24. In the production of such a room module 8 designed as a garage module, concrete is used as the hardenable mass. It is therefore necessary for the required stability of the garage module to work a reinforcement 21, preferably made of steel, into the concrete. This reinforcement 21 is according to the illustration of Figure 8 arranged around the core formwork 10 or around its side elements 12, 13, 14 and 15 and its head element 11.

After the reinforcement 21 has been arranged around the core formwork 10, this arrangement is now provided with an outer formwork 9, as shown in FIG Figure 9 is shown.

It can be seen that between the core formwork 10 or its side elements 12, 13, 14 and 15 and its head element 11, an intermediate space 22 is formed, within which the reinforcement 21 is arranged. In this case, an outer formwork 9 does not necessarily have to be arranged in the area of the head element 11 of the core formwork 10, since due to the vertical positioning of the core formwork 10, the concrete aligns itself according to the force of gravity parallel to the head element 11 of the core formwork and only needs to be smoothed there if necessary.

The space 22 is now filled with the hardenable mass, in this case with concrete, and the entire device according to the invention remains in this position together with the Outer formwork 9 and the not yet hardened mass until it has hardened.

As soon as the mass or the concrete has hardened, the outer formwork 9 can be removed. After the concrete has hardened, the room module 8 designed as a garage module has already formed. However, the core formwork 10 still has to be removed from the interior of the room module 8 designed as a garage module. For this purpose, the vertically positioned room module 8, as shown in FIG Figure 10 is shown, tilted using a tilting device, not shown here, so that the room module 8 comes to rest on its base plate 25. In this position, the core formwork 10 is no longer positioned vertically, but horizontally, as shown in FIG Figure 11 is shown.

In the position according to the Figure 11 the first surface elements 1 of the head element 11 of the core formwork 10 are now lowered, moved against each other and then the second surface elements 2, designed as triangular elements 27, also move against each other while reducing the rectangular area of the head element 11. The reduced rectangular area of the head element 11 is in the Figure 12 indicated by the thicker lines compared to the room module 8 or its side wall 24.

The third and fourth surface elements 3 and 4 of the core formwork 10 are then adapted to the reduced rectangular area of the head element 11 by being moved in the direction of the central longitudinal axis 16 of the core formwork 10, as in FIG Figure 13 shown. As a result, a gap 20 is formed in the area of the side elements 12, 13, 14 and 15 between the core formwork 10 and room module 8, so that the core formwork 10 can be moved out of the interior of the room module 8. This is in Figure 14 shown schematically.

The room module 8 thus produced and designed as a garage module can now be used for further processing or use, and the core formwork 10 can be used to produce further room modules 8.

The room module 8 has a floor element 25, a ceiling element 26 and three side elements 24, that is to say already has five surfaces. At the opening 30 of the room module 8 designed as a garage module, a garage door can be arranged as the area closing the room module 8, so that no other garage door than this arrangement Processing steps are necessary to produce a finished garage.
