Abstract

The invention relates to a method for producing prefabricated parts from mineral-bound building materials for the erection of buildings by means of a manufacturing system, wherein the manufacturing system comprises formwork tales that are provided for casting the prefabricated parts from mineral-bound building materials, wherein the manufacturing system is mobile and is brought to the erection site of the building for manufacture of the prefabricated parts.

Description

The invention relates to a process for the manufacture of finished components from mineral-bound construction materials by means of a manufacturing plant according to the characteristics of claim 15 and a manufacturing plant for the manufacture of finished components from mineral-bound construction materials according to the characteristics of claim 1.

In particular, the construction of buildings requires a high expenditure of personnel, time and transport logistics.

There are several methods of manufacturing prefabricated houses: One way is to have a company build a so-called turnkey house, which is usually finished in about six weeks.

The main advantage of this method is that it is not a simple process, but it is a method of production which is not always easy to implement, and which is not always easy to implement.

In both cases, the production of the finished parts is abandoned for manufacturing and logistical reasons.

The production of finished parts usually takes place in factories, from which the finished parts or the complete workshops are then transported to a desired site.

The purpose of the invention is therefore to demonstrate a method for the manufacture of finished components from mineral-bound construction materials which makes it possible to manufacture different finished components, in particular walls, floors and ceilings or complete structures, near the place of use of the finished components.

The state of the art already provides a variety of devices and processes for the production of finished components.

For example, US 2003/0234339 A1 reveals a device for the manufacture of components such as walls, floors, ceilings and roofs. The device has one or more tables mounted on a trailer. For storage and transport purposes, the tables are in an upright position. For the manufacture of the components, the tables are placed in a horizontal position.

DE 2 154 956 A also describes a transportable machinery for the manufacture of precast concrete components of all kinds. The machinery consists of a conveyor, the production frame mounted on it and the additional shapes. The conveyor allows the transport of the production equipment in the form of a trailer and for this purpose has, for example, wheels with the axles, bearings and a rotary shaft as a curved chassis.

US 4.207.042 describes a machine for the horizontal casting of concrete wall panels and their installation in rooms or single-storey buildings. The machine has rails and a frame which can be walked on the rails. Two moulders for the casting and laying of longitudinal wall panels are mounted on the frame and can rotate more than 90° parallel to the rails.

DE 10 2006 051 045 A1 also concerns a device for the manufacture of precast concrete components. The complete equipment for the manufacture of precast concrete components is housed in a cargo container that can be removed directly from a construction site. The cargo container also forms an air-conditioned air-cured room. In particular, a rail system arranged in the cargo container is proposed for the orderly loading and unloading of the equipment.

DE 2 034 205 A1 also describes a device for the manufacture of concrete elements. The device has a loading chamber in which moulds for concrete elements are arranged horizontally on top of each other. To speed up the bonding process, the loading chamber can be heated to a desired temperature by blowing hot air in. Furthermore, the moulds can be ejected from the loading chamber by means of rails and wheels.

WO 01/29337 A2 finally teaches a method and device for the manufacture of parts of a structure. The device has a mould with a working surface on which the parts are manufactured. The mould has a movement mechanism which allows the parts to be moved to almost any position.

A manufacturing plant in conformity with the invention is the subject of claim 1.

The procedural part of the task is solved by a procedure with the characteristics of a patent claim 15.

The dependent sub-claim relates to advantages in continuing training.

In the case of the method of the invention for the manufacture of finished components from mineral-bound construction materials, in particular for the erection of buildings by means of a manufacturing plant, the manufacturing plant used comprises as an essential component at least one switchboard designed to cast finished components from mineral-bound construction materials. The manufacturing plant is mobile and can be moved to the place of use of the finished components and, in particular, to the construction site of a building, for the manufacture of the finished components. This mobility thus makes it possible to transport a complete small factory for the manufacture of finished mineral-bound construction materials to various locations.

The necessary binders, rock grains, starting water and any additives for the production of mineral-bound building materials can be transported more easily than bulky finished parts already made from them, which often have a significant weight due to their size.

The method of the invention allows, in particular, the manufacture of the following finished components: Wall, ceiling, floor, foundation or stone elements, facade elements, plasterboard, dam or fence elements.

In particular, prefabricated components of very different densities can be produced on site, e.g. from concrete and a much lighter insulation material.

The invention is based on the fact that the entire production plant fits into a cargo container, which is transported to the site by means of a truck. The cargo container can be easily transported by air, water or land. The production plant can therefore be transported to any place to which a road leads.

The plan is to place the switchboard in a horizontal position to cast the finished parts and to tilt it to or after the shell on a horizontal axis. In the horizontal position, a mixture of mineral building material is put into the mold. In this position, the mineral building material can be removed. After the mineral building material is then tied up in the mold, it can be turned off. To remove wall elements, the switchboard is tilted around the horizontal axis so that the dried finished pieces can be removed.

The advantage of this is that several finished parts can be produced independently at the same time. While a wet mixture of mineral building material is being cured on one switch, the already cured component can be removed on another switch. A new mixture of mineral building material can be poured into a third molding of another switch at the same time. It is also advantageous that differently configured finished parts can be manufactured at the same time. Floors, ceilings and walls can be fitted with variable curing for doors and windows. This allows the use of standard or individual shapes.

The pressure is applied to the control panel by means of a linear drive, which is used to apply pressure to the control panel from one of the bottom surfaces of the control panel opposite the control panel, and is placed below the control panel, between the control panel and the respective substrate or a corresponding substrate, such as a support.

In order to achieve the most stable and balanced behaviour, and in particular a low-twisting displacement and inclination of the switchboard, the compressive force shall be applied in the area of the centre of gravity of the switchboard.

The linear drive may provide a safety advantage over a pulling force applied to the switchboard's tilt. The pulling force is transmitted by means of appropriate traction devices, such as ropes or chains, the failure of which leads to a most pronounced tip of the switchboard. The resulting danger to the operator and possible damage to the system is avoided by the linear drive having a back-up protection against back-up. This back-up protection may already be available in the design, for example if a self-locking spindle or dental drive is used.

The linear drive is preferably hydraulically driven. It is preferably a single-acting or double-acting lifting cylinder. Oil, water or an oil-water emulsion can be used as a fluid for the hydraulic drive.

The safety element is designed to prevent the unwanted fall of the switchboard, which is inclined out of its horizontal position and thus placed, effectively. The safety element may be, for example, a reverse valve. In addition, pressure limiting valves may be provided to protect against overpressure.

The force of actuation required to operate the linear drive can be provided by both muscle power and a suitable drive. To increase the force of actuation, suitable force transducers are provided, i.e. gears or pressure transducers coupled to a pump. Of course, the pump can also be operated by muscle power. The pump can also be operated by motor, for example via an electric motor or a combustion engine.

The advantage of this is that on a production plant with several switching tables, several finished parts can be created in parallel, which can be tilted to the required side if necessary and thus placed.

For example, it may be advantageous for the finished part to be positioned on the side facing the switchboard's respective face, which forms the outer face of the wall elements, so that the finished parts do not have to be turned extensively before being placed at their destination.

The switch tables are particularly passable. Preferably they are stored on a support which is moved out of the freight container on rails and into the container when not in use. The move can be done on a railed or unrailed system. The switch tables can be moved into the freight container when not in use, after work has been completed, to protect against inclement weather or to protect against theft and can be processed in particular.

It is possible that the end of the linear drive can be moved in the same direction as the switchboard. Preferably, the end of the linear drive facing away from the switchboard is soluble coupled to the support. The coupling can be done, for example, via a soluble bolt. For this purpose, the support has at least two opposite sockets, with the said end of the linear drive being optionally coupled to one or the other socket.

The linear drive is conveniently coupled to the support of the frame, which is opposite the horizontal axis, around which the switchboard is to be tilted.

The switchboard may have a chassis. The chassis allows the switchboard to be driven autonomously. Of course, the chassis can also be located on the chassis on which several switching tables are stored. The chassis allows the switchboard to be driven between its possible places of operation. In the same way, several switching tables arranged on the chassis can also be driven together between their places of operation, provided that the chassis is located on the chassis.

Depending on the design of the chassis, this allows access to hard-to-reach places of use on unpaved terrain. In addition to the process between possible places of use for the production of finished parts, finished parts already manufactured and still in the mould can be moved to the place of installation or installation. This is particularly advantageous if no suitable lifting equipment with a sufficient radius of action is available or can be used to move the finished parts far enough.

In a favourable training, the scaffolding which holds the switchboard or the switchboard is so trained that it can be converted from a transport size to a working size by disassembly. In other words, the scaffolding is thus changed in its dimensions, being pushed together as space-saving as possible while it is inside the cargo container, while it is disassembled outside the cargo container to its full or currently required size. In this way the scaffolding is lengthened or shortened. The scaffolding consists of individual elements linked to each other by joint connections.

Unlike the production of finished parts in closed buildings, the transfer of the switchboards from the cargo container offers the possibility of using solar and wind energy for drying the finished parts.

The switch tables of the invention have joints which allow the switch tables to be folded up to a width exceeding the width of the cargo container in a position of use. The folding capacity of the switch tables allows for the production of larger finished parts. In addition, it is possible to create a large common area from the individual switch tables, which allows a high variation in the size of the finished parts. The method makes it possible to produce single-storey bungalows as well as multi-storey buildings, e.g. single and multi-family houses, school buildings, hospitals or other public institutions.

Another possibility of enlarging the switch tables is provided by means of external modules, which also allow a position of use exceeding the width of the cargo container.

The switch tables are preferably designed or extendable to cover a minimum area of 2.5 m x 2.5 m to 5.0 m x 5.0 m. In particular, if several switch tables are arranged in a row, they can cover a total area of 5.0 m x 10.0 m to 5.0 m x 50.0 m. In the latter case, the supporting structure is extendable to accommodate a total of 10 of the switch tables with a grid of 5.0 m x 5.0 m.

By linking the individual linear drives together, the interlocking switchboards can be tilted in the same direction at the same time, thus also enabling large finished components to be removed by their erection.

Of course, even in this case individual switchboards can be tilted in different directions or not at all, depending on the respective dimensions of the finished parts to be manufactured.

The system is then extended to the required size and the required number of switchboards are placed on it. If necessary, the switchboards are extended beyond the possibilities previously indicated in relation to their respective switch area. These are then coupled to the system, for example by means of soluble bolts on one of the horizontal axes around which the respective switchboard is to be tilted. Furthermore, the linear drives are arranged between the switchboard and the system and solubly coupled to them. The necessary control of the linear drives is achieved by their total or partial coupling to each other.

The production plant can be placed in the cargo container in such a way that the switch tables are first removed and folded down if necessary and/or the external modules are removed. The support structure is then pushed together and inserted into the cargo container. Finally, the individual support structures are stacked on the support structure and any external modules are also placed in the cargo container.

The operation of the switchboard and the assembly of the finished components is easy and quick to learn, and even after relatively short instruction and training periods, most work can be carried out independently by local staff.

The invention also includes a production plant for the production of finished components from mineral-bound construction materials. The production plant includes at least one switchboard designed to cast finished components from mineral-bound construction materials. The switchboard is mounted on a support which, together with the switchboard, can be transported in a cargo container to the place of use of the finished components, i.e. usually to the construction site of the building/structure to be constructed, and can be moved out of the container on site and in particular easily driven out.

The production facility is suitable for all types of mineral building materials, and the advantage is that the freight container has the commercial unit of a 20 and/or 40 foot container, which can also be easily transported by air or sea.

The frame has particularly favourable rolls which are trackable on rails. The rails are carried in the cargo container. The invention provides that a transport path of the switchboard is allowed up to 40 m.

In principle, however, it is also conceivable to equip the switchboards without a rail/roll system and to transport the switchboards from the freight container by lifting or by a hydraulic cable-independent pump system.

In a further development of the invention, the chassis has a suspension, over which the suspension can be driven together with at least one shift table. This suspension does not mean the rail/roll system, with which the switches can be driven out of the container. The suspension is used for unbounded movement by rails. The suspension can be, for example, a bicycle or a crawler drive. The crawler drive as a chain drive has the advantage that it can also be used on rough terrain.

The structure is advantageously designed with longitudinal supports which can be moved at least translatively against each other to extend and shorten the structure.

The longitudinal beams may be either sideways or inside each other, and may have a sideways open or closed cross-section to allow the necessary length change of the structure.

In a further development, it is envisaged that the structure comprises individual strokes which outline the longitudinal strokes of the structure. In order to obtain a variable and yet sufficiently well-developed system, it is envisaged that at least some of these strokes are in themselves shortened and/or extended.

This allows the support to be dismantled from a transport position to a drop position without the need to remove or attach any elements, thus ensuring that the production plant is ready for use very quickly.

Each switchboard has an individual frame molding which allows for the production of frames which vary in height and width. Individual frame moldings also include insert moldings for insulation or window and door moldings (wet-in-wet process) and utility moldings for laying water and electricity pipes. Individual frame molding allows for a very precise definition of the desired material thickness. In addition, a well-defined second layer, e.g. an insulation layer, can be applied.

The individual frame shells can also be used to produce the mix of mineral-bound building materials directly on site, for example by using local raw materials, which will result in considerable CO2 savings due to the elimination of transport routes.

The switch tables have joints through which they can be folded down to a width which is significantly greater than the width of the cargo container.

It is also possible to enlarge the switchgear by using external modules, which enlarge the switchgear to a width significantly exceeding the width of the cargo container.

The switch tables are mounted on the frame in a way that allows them to be moved around a horizontal axis, allowing the switch table to be adjusted at different angles.

The purpose of the pivot bearings is to raise the respective switchboard from its horizontal position by tilting the switchboard by at least one, preferably by at least two, of the pivot bearings; the pivot bearings are designed and arranged in such a way that the switchboards are tilted by at least two parallel horizontal axes in different directions around an angle of inclination.

The angle of inclination may be from 0° to 89°.

In order to allow for a convenient and practical manufacture and for the most appropriate arrangement and removal of finished parts, at least one of the switch tables may include a rotary bearing so that a switch table can be rotated along a rotation axis perpendicular to its axis.

This allows the entire switch surface to be rotated in its plane if necessary, in order to achieve a practical orientation of the switchboard, for example in relation to local conditions.

The switch tables include both longitudinal and transverse profiles as well as cross-curved cross-curves. These profiles form a sub-construction of the respective switch table on which the actual switch surface is arranged. The sub-construction serves to provide the necessary stiffening of the switch table, especially the switch surface.

The node shall be located in the area of the respective centre of gravity of the switchboard.

The resulting power triangles in particular make the corner areas of the switchboard in its plane and thus the flat geometry of the switchboard almost immutable. This ensures that the geometry of the switchboard is maintained even after repeated use, even when the equipment is roughly handled on a construction site.

A further advantageous development is that the cross profiles each include an angle between themselves and the switchboard's switch surface. Thus, the cross profiles do not run parallel to the plane of the respective switch surface, but are arranged at an angle to it. Preferably, the angle opens to the node of the cross profiles.

In this way, the substrate formed by the substrate extends below the surface of the switchboard not only in the plane of the surface of the switchboard, but also perpendicular to it, resulting in an extremely rigid substrate which provides the greatest possible torsional rigidity of the surface of the switchboard even at high surface pressures caused by the introduction of the mineral material and the finished part itself.

In particular, when the finished parts are not yet completely cured, the inclination of the switchboard can effectively prevent undesirable deformations of the finished parts, which are usually concentrated on the corner areas of the switchboard.

The advantage of the linear drive is that the force generated by the linear drive between two inherently rigid arrangements of the production plant, namely the substructure and the support, is thus improved, thus improving the effectiveness of the linear drive and in particular the control and precise adjustment of the required angle.

In particular, by coupling the linear drive to the hub of the sub-construction of the individual switchboards, a central introduction of the applied pressure force is possible, which is achieved without additional supports for the switchboards. This is achieved by the specialised sub-construction of the switchboard, which from the central hub causes a pressure load distribution over the entire shelf surface.

In this context, it is envisaged that the linear drive is soluble coupled to the respective node of the switchboard and the support structure. In this way, the linear drive can be easily implemented if necessary and also easily extended for the transport of the production plant in the cargo container. Thus, depending on the direction and thus the horizontal axis used, the linear drive can be coupled to the deflection of the switchboard at different areas of the structure to achieve the highest possible efficiency. For this purpose, the support structure has at least two separate receptacles, which can be connected to the support structure via the linear drive.

The invention provides that there is one linear drive per switch table.

The invention allows several switch tables to be arranged on a frame, the advantage being that the respective switch tables can occupy different working positions at the same time.

It is particularly desirable to have three independent switching tables on a support, for example, a wet mixture of mineral-bound building materials can be placed on a first switch, while the mixture of mineral-bound building materials is already being dried on a second switch and the dried finished part is being removed at the same time on a third switch.

In the case of several work tables on a frame, the work tables are directly adjacent, thus creating a larger common work area.

A scale is preferably placed on the switch tables to facilitate precise setting of the frame moulding.

The invention is explained in more detail below by means of an example of an embodiment shown in the drawings.

Figure 1 shows a manufacturing plant according to the invention. It comprises a conventional cargo container. In cargo container 2 there are rails 3 on which a transportable platform 4 (Figure 3) is stored. On platform 4 there are three independent switchboards 5, 6, 7 and 4 reels 8 on the platform.

The production plant 1 in Figure 1 is not yet in use. The switch tables 5, 6, 7 are folded down so that they can be stored in freight container 2 without problems. Freight container 2 can transport up to 40 m of hull length with a hull width of up to 5 m. In this example the length is almost 40 feet for a width of about 3 m.

Figure 2 shows the production plant 1 from Figure 1 with extended rails 3 on which the rails 4 are moved out of the freight container 2 with the switching tables 5, 6, 7. The switching tables 5, 6, 7 are now in the unfolded condition. The rails 3 can also be extended to a length not shown here of up to 40 m.

In the position of the cargo container 2, the switchgear 5, 6, 7 can be put into operation directly, but the supporting bearings 4 and 5, 6, 7 can also be used on any other load-bearing surface.

Figure 3 shows again the rails 3 on which the serviceable rack 4 is located, on which in turn the shift tables 5, 6, 7 are stored in a swivel position. Two of the three shift tables 5, 6 are folded out in a horizontal position. The third shift table 7 is inclined around a horizontal axis A. The rack 4 consists of two longitudinal bearings 9, which are connected by several transverse bearings 10. On the loaders 10 and the longitudinal bearings 9 are located on the side facing the rails 3, the reels 8.The switch tables 5, 6, 7 are arranged on three legs 11 on the longitudinal supports, each of which can be rotated over the pivoting axis S, so that they can be tilted around the horizontal axis A. The angle of inclination W (Figure 4) is no more than 85° The switch tables 5, 6, 7 consist of several longitudinal and transverse profiles 12, 13. The switch tables 5, 6, 7 are shown in Figure 3 in the folded state. On the switch tables 5, 6, 7 different sized finished products can be cast.The hydraulic pressure can be applied manually, electrically, by emergency power supply or by coupling to an external source of pressure, such as a truck or construction machine.

Figure 4 shows a representation of the switchboard 5, 6, 7 on the support 4 in horizontal and upright position. On the support 4 there are rollers 8 which are mounted on a rail profile 15. The rail profiles 15 are at the very bottom of the picture plane. On the support 4 there are the legs 11 which support the switchboard 5, 6, 7. On the right leg of the picture 11 there is the pivot beam S over which the support 4 is coupled to the switchboard 5, 6, 7. Along the horizontal axis A passing centrally through the pivot beam, the switch is pivot 5.The switchboard 5, 6, 7 can be folded up to a maximum of 89° relative to its horizontal position. On the switchboard 5, 6, 7 and the support 4 there are reception devices for steel tube joints 16 not shown here, to which a bottle pull F can be attached, which then represents a possibility for the folding of the switchboard 5, 6, 7. In the embodiment of the switchboard 5, 6, 7 shown here, this has an external module 17 to increase its width, which is clearly visible in the image on the left.6, 7 screwed up.

Figure 5 shows two of the switch tables 5, 6 in an alternative layout. The switch tables 5, 6 include both the longitudinal profiles 12 and the transverse profiles 13, with these being supplemented by cross profiles 19 running diagonally to these. The cross profiles 19 are connected to each other at a common junction 20. The junction is located in the area of the centre of gravity of the respective switch tables 5, 6.

In relation to the respective switch surface SF of the switch tables 5, 6 the longitudinal and transverse profiles 12, 13 shall each enclose an angle between themselves and the respective switch surface SF of the switch tables 5, 6 which opens to the node 20.

Figure 6 shows the schematic layout of the alternate switchboards 5, 6 from Figure 5 in a side view. As can be seen, between the support structure 4 and the junction 20 of switchboard 5 a linear drive 21 is arranged in the form of a lifting cylinder to deflect the switchboard 5.

Furthermore, the support structure 4 has two opposite swing bearings S, so that the switch table 5 can be tilted in different directions if necessary, and the switch table 5 is connected to them in a non-detailed manner by means of soluble bolts on only one of the two sides of the swing bearings S, so that the opposite swing bearing S has no coupling to the switch table 5.

The linear drive 21 is soluble coupled to the junction 20 of switchboard 5 and to the support 4; for this purpose, in particular, the support 4 has spaced out interconnecting sockets 22 with which the linear drive 21 can be optionally coupled.

The selective coupling with one of the 22 beams depends on the direction of inclination of the switchboard 5. If a tilt of the shaft table 5 around the left pivot beam S is to be made, as shown in Figure 6, the linear drive 21 is coupled to the support 4 via the right beam 22 as shown. If a tilt around the right pivot beam S is to be made, the linear drive 21 is coupled to the support 4 via the left beam 22 Theoretically, a position in the middle is also possible so that the lower end of the linear drive 21 is closer so that the end coupled to the 22 beam does not have to be displaced.

Figure 7 shows an alternative design of a production plant. To allow the most self-sufficient mobility of the respective switchboard 5, 6, 7, the chassis 4 has a chassis 23. The chassis 23 is trained as a crawler chassis.

Figure 8 shows an alternative design of the structure 4. The schematic illustration shows parallel longitudinal support beams 9a, which are pushed together in a shot-like fashion.

Figure 9 shows the arrangement of the longitudinal beams 9a arranged in a cross section A - A. The longitudinal beams 9a are C-profiles. The longitudinal beams 9a arranged in each other have different cross-sectional dimensions, which means that several, in this case three longitudinal beams 9a, are interlocked. At the ends of their legs, the longitudinal beams 9a are perpendicular to them and have a platform 24 facing each other, so that each outer longitudinal beam 9a encloses the longitudinal beam 9a arranged in it in three directions, while the fourth side is surrounded by the 24 steps. The 24 steps are dimensioned so that their ends are parallel to each other.

Looking back at Figure 8, 10 diagonal struts 25 are placed next to the cross-beams connecting the longitudinal supports 9a. The struts 25 cross a section of the present self-coupled structure 4. The advantage is that a possible displacement of the frame formed by the longitudinal supports 9a and the cross-bearers 10 is effectively prevented by the struts 25.

In this Regulation, the truss 4 which is compressed in the direction of the longitudinal supports 9a for one third of its total length may carry a switchboard 5, 6, 7 not shown here by means of its supports.

In addition, the support 4 has additional 25a strings which, in the present combined condition of the support 4, have a significantly smaller angle between them than the strings extending the existing section of the support 4 25. The strings 25a are in a non-detailed way mobilityally coupled to the individual longitudinal strings 9a. Each of the strings 25a extends between the differently pointing ends of two longitudinal strings 9a running parallel to each other, one end of which is coupled to a longitudinal strings area, while the other end of the support 25a is connected to a longitudinal strings area running parallel to it, which is however adjacent to a section 4 running parallel to it.

For example, to enlarge the support 4 to its full length, the longitudinal support 9a arranged in a mutual position are pulled apart in a direction of expansion x of the support 4.

Figure 10 shows the full-length expansion of the support structure 4 from Figure 8. This means that support structure 4 has, in addition to its fixed section Z1, subsequent variable sections Z2, Z3, which are also used for the reception and storage of tables 5, 6, 7 not shown in detail.

As can be seen, the strands 25a undergo a change in length in the direction of expansion x of the structure 4 during the extension. This is due to the distance resulting from the separation of the longitudinal bearings 9a from anchorage points 26 which are arranged at the respective longitudinal bearings 9a and between which the strands 25a extend diagonally.

The strokes 25a are designed to allow length variation. For this purpose, each of the strokes 25a has a strut 27 arranged in soft lengths 28 at each end. The lengths 28 flee with the respective struts 27. In another embodiment, each of the struts 25a can also have only one strut 27 with a single long element 28.

The longitudinal elements 28 may be carried in the strut bodies 27 by means of hollow strut bodies 27 such as circular or rectangular tubes, and of course the longitudinal elements 28 may also be hollow and thus incorporate the strut body 27.

The coupling between the strut 27 and the long elements 28 is both soluble and arresting. This allows the longitudinal bearings 9a to be easily disengaged when the coupling of the strut 27 with the long elements 28 is disengaged. Once the longitudinal bearings 9a are disengaged to the required dimensions of the structure 4, the coupling between the strut 27 and the long elements 28 is arrested, so that a stable variable stretch section of Z22, Z32, Z32, takes place.

The previously shown design of the 25a struts enables the supporting structure 4 to have more than the three sections Z1, Z2, Z3 shown here. The arrangement of the 25a self-coupled and elongated struts in combination with the inter-sliding longitudinal struts 9a provides an extremely simple way to expand a supporting structure 4 to the required length in a very short time without the need to disassemble or arrange individual components.

Despite its extremely simple operation, this creates an extremely safe system for the construction of a production plant of the invention 1 which provides an effective scaffolding 4 with a few handles and which can be adapted to local requirements.

Figure 11 shows the combined support 4 from Figure 8 in another variant. As can be seen, this one has a rotary bearing 29 in its fixed section Z1.

Of course, the rotary bearing can also be located at at least one of the switching tables 5, 6, 7 not shown here.

Figure 12 shows the support 4 in the direction of expansion x in a side view. In this representation each of the switchboards 5, 6, 7 has a rotating bearing 29.

The disassembly of the support 4 in the x-expansion direction can be done by hand or by motor. For example, a type of bottle pull can be arranged inside or outside the longitudinal bearings 9a, so that by pulling a tractor a corresponding extension or shortening of the support 4 can be made.

The resulting decrease in the upper flow of the structure 4 due to the different longitudinal bearings 9a can be compensated by balancing elements not shown in detail, such as those between the longitudinal or transverse bearings and the respective switchboards 5, 6, 7 and their substructure.

In principle, leveling elements which are not shown in detail may be arranged between the switch tables 5, 6, 7 and the support structure 4.

Figure 13 shows in a diagram the possible directions of deflection of the switchgear 5, 6, 7 of the production plant 1. As can be seen, the switchgear 5, 6, 7 can be tilted over the swing bearings S, which are arranged on both sides of the length of the structure 4, which allows the respective position of the switchgear 5, 6, 7 to be changed.

Figure 14 shows the condition of the production plant 1 for its transfer to the freight container 2 not shown in detail. For this purpose, the switch tables 5, 6, 7 are tilted so that the modules 17 connected to the switch tables 5, 6, 7 by the joints 14 can be folded down. The aim is to reduce the width of the switch tables 5, 6, 7 reached by the modules 17 so that the entire production plant 1 corresponds to the maximum light width of the interior of the freight container 2. In this way, the significantly larger shelf area SF on production plant 1 can be reduced to a compact size by the corresponding transfer of the switch tables 5, 7 and 17 to be transported within the freight container 2.
