DETAILED DESCRIPTION OF THE FIGURES
[0069] FIG. 1 shows a perspective representation of an embodiment of a system 100 according to the invention. FIG. 1 schematically shows a detail of an embodiment of a system 100 according to the invention. The system 100 comprises a frame section 3 which is shown at the front right. The frame section 3 extends three-dimensionally in three spatial directions and comprises a plurality of vertically oriented vertical posts 51. The frame section 3 further comprises a plurality of horizontally oriented horizontal bars 52. The vertical posts 51 and the horizontal bars 52 are connected to one another via interfaces. The frame section 3 is constructed in a modular manner, which means that different shapes and sizes of frame sections 3 can be assembled according to the modular principle from standard components such as the vertical posts 51 and the horizontal bars 52. The frame section 3 shown here comprises three tread levels which are arranged one above the other and can be walked on by workers. The system 100 further comprises at least one formwork panel 2. In the embodiment shown, a plurality of formwork panels 2 are provided, which are connected to one another at their edges and together form a formwork. The formwork panels 2 are connected to one another via formwork locks. In the embodiment shown, a support M, which supports and holds in position the formwork panel 2 and the system 100, is attached to the front of the formwork panel 2. However, this support M is optional here, the system 100 is also capable of supporting a load without this support M, wherein the frame section 3 supports and positions the formwork panel. The system can thereby also be used in a free-standing manner, in particular without the support M. Each formwork panel 2 comprises a framework 21 which forms the supporting and load-bearing element of the formwork panel 2. On the framework 21, a formwork skin 22 pointing to the rear left in the representation is releasably fastened to the framework. This releasable arrangement of the formwork skin 22 enables a simple replacement of the formwork skin 22, for example when it is worn. The framework 21 comprises a plurality of cross struts 212 oriented horizontally in the representation and a plurality of longitudinal struts 211 oriented vertically in the representation. The longitudinal struts 211 and the cross struts 212 are oriented substantially perpendicular to one another. The formwork skin 22 rests at least in regions on the longitudinal struts 211 and the cross struts 212. Undercuts 213 are arranged in each case on the cross struts 212, running in their longitudinal direction, whereby grooves are formed with a rectangular cross-section. Details of a cross strut 212 with an undercut 213 are shown in FIG. 3. The undercuts 213 are provided to be connected to a connection component 1 in a form-fitting and frictionally engaged manner. It is also possible for one or more undercuts 213 to be arranged on one or more longitudinal struts 211 for fastening a connection component 1. Furthermore, it is possible to arrange further struts in the framework 21, which are oriented at different angles to one another and which can also have one or more undercuts 213. FIG. 1 furthermore shows three connection components 1 which also belong to the system 100. These connection components 1 connect the formwork panel 2 to the frame section 3. In the embodiment shown, each connection component 1 has two formwork interfaces 12 which are connected to the framework 21 of the formwork panel 2. Details relating to a connection component 1 and its interfaces are shown in FIG. 2. Each formwork interface 12 comprises a clamping element 121, which in turn comprises two gripping arms 1211. The gripping arms 1211 engage in an undercut 213 in regions and thus form a form fit between the formwork interface 12 and in the framework 21, in particular a cross strut 212, of the formwork panel 2. One of the two gripping arms 1211 is designed to be movable relative to another gripping arm 1211. The distance between the two gripping arms 1211 is thus adjustable, whereby the clamping element 121 can be brought into engagement with one or more undercuts 213. Each connection component 1 further comprises a support element 13, to which the formwork interface 12 is fastened. The support element 13 is rod-shaped and is formed here by a tube with a round cross-section. The support element 13 has a longitudinal axis which extends in the vertical direction in the representation. The longitudinal axis of the support element 13 is arranged substantially parallel to the surface of the formwork skin 22. In the embodiment shown, the support element 13 is designed to be very similar to a vertical post 51 of the frame section 3. In the embodiment shown, the connection component 1 simultaneously forms a vertical post 51 of the frame section 3 in functional combination. Furthermore, in the embodiment shown, a plurality of frame interfaces 11 are arranged on the support element 13 and are arranged here at regular intervals along the longitudinal axis of the support element 13. The frame interfaces 11 of the embodiment shown correspond to interfaces which are also arranged on the vertical post 51 of the frame section 3. The frame interfaces 11 can thus be connected in the same way to other components or elements of the frame section 3, such as the interfaces which are arranged on a conventional vertical post 51. As a result, the connection component 1 is fully integrated into the frame section and can be combined in a modular manner with other components of the frame section 3. The frame interfaces 11 are designed here as connecting disks or rosettes. Both the connection between the frame interface 11 and the frame section 3 and the connection between the formwork interface 12 and the formwork panel 2 are also designed to be capable of supporting a load, such as connections within the frame section 3. A force transmission between the formwork panel 2 and the frame section 3 by the connection component 1 is thereby possible. In this way, the system 100 can be used in a free-standing manner, since the formwork panel 2 and the frame section 3 support one another and hold them in position. Furthermore, it is possible to transport the system with the aid of a crane, wherein it is sufficient to connect the crane either to the formwork panel 2 or to the frame section 3. The other component of the system 100 is held on the crane by the connections by the connection component 1. FIG. 1 clearly shows that the selected embodiment of a connection component 1, which forms a vertical post 51 in functional combination, can save additional vertical posts 51 in the frame section 3. The system 100 according to the invention thus reduces the weight of a connection between formwork panel 2 and frame section 3. Furthermore, components for the frame section 3 are saved compared to the prior art. In the embodiment shown, it is provided that, when the system is constructed or during the production of the wall element, the formwork panel 2 and the frame section 3 remain connected to one another by the connection component 1. However, the connections to the connection component 1 are releasable in a simple manner, so that a separation of formwork panel 2 and frame section 3 is also possible in a simple manner, for example when the system is disassembled.
[0070] FIG. 2 shows a side view of a connection component 1 in functional combination with a vertical post 51. FIG. 2 shows a connection component 1 according to the embodiment which is also shown in FIG. 1. The connection component comprises a support element 13, the longitudinal axis of which is oriented vertically in the representation. Two formwork interfaces 12 are arranged on the support element 13 pointing to the left, spaced apart from one another. A total of eight frame interfaces 11 are arranged on the support element 13 opposite the formwork interfaces 12, likewise at a distance from one another. Six of these frame interfaces 11 are designed as connecting disks or rosettes which extend to the right from the support element 13. These connecting disks or rosettes are identical or at least very similar to interfaces which are also arranged on a vertical post 51 of the frame section 3. A connection of components of the frame section 3 to the frame interfaces is thus possible in the same way as in the case of a connection of components within the frame section 3 constructed in a modular manner. The upwardly facing end and a recess in the downwardly facing end of the support element 13 are also frame interfaces 11. These two frame interfaces 11 can be used to produce a connection to vertical posts 51 of the frame section 3 by insertion at the ends of the support element 13. The frame interfaces 11 are arranged on the support element 13 at intervals from one another which correspond to the grid of connection interfaces in the frame section 3. In the embodiment shown, the connection component 1 can thus be integrated fully into the frame section 3. Each formwork interface 12 has a clamping element 121, which in turn comprises two gripping arms 1211. The lower of the gripping arms 1211 is designed to be immovable relative to the support element 13, whereas the upper of the two gripping arms 1211 is designed to be movable relative to the lower gripping arm 1211. The clamping element 121 furthermore comprises an unlocking mechanism 1220, which can be operated via a lever. The distance between the two gripping arms 1211 can be changed by the unlocking mechanism 1220. In order to connect the connection component 1 to the formwork panel 2, the unlocking mechanism 1220 is initially actuated such that the distance between the two gripping arms 1211 is greater than the width of a cross strut 212 of the framework 21. In this state, the two gripping arms 1211 are pushed over the cross struts 212 in regions. Subsequently, the unlocking mechanism 1220 is actuated so that the distance between the two gripping arms 1211 is reduced. A projection 1211a, which is arranged at the tip of the gripping arm 1211 pointing to the left, penetrates into an undercut 213 on the cross struts 212. Details regarding this connection can be seen in FIG. 3. By further actuation of the unlocking mechanism 1220, the cross strut 212 is then clamped between the gripping arms 1211. In this state, there is then a form fit and a frictional engagement between the formwork interface 12 and the framework 21. In the embodiment shown, each clamping element 121 has an unlocking mechanism 1220 which is operated individually. However, it is also possible to couple the unlocking mechanisms 1220 of both formwork interfaces 12 to one another, for example by a connection to a cable or a rod. In this coupled embodiment, both unlocking mechanisms 1220 can then be operated simultaneously. This accelerates the connection and the separation between connection component 1 and formwork panels 2. The distance between the two formwork interfaces 12 in a direction parallel to the longitudinal axis of the support element 13 corresponds to an integer multiple of the distance between two cross struts 212 of the formwork panel 2 from FIG. 1. A compatibility between the grid of the connection component 1 and the grid of the formwork panel 2 is thereby ensured. Due to this compatibility of the grids, the connection component 1 can be securely and stably fastened flexibly at different positions of the formwork panel 2, without further components having to be arranged in between for compensating a grid difference. Alternatively, it can be provided that the position of a formwork interface 12 on the support element 13 is provided adjustably in order to compensate for tolerances. In addition, a compensating element 14 can be provided which allows the formwork interface 12 to be displaced relative to the support element 13 in the longitudinal direction thereof. However, such a compensating element 14 is optional and therefore not shown in FIG. 2. A compensating element 14 can also be arranged between the support element 13 and one or more frame interfaces 11.
[0071] FIG. 3 shows a sectional view through a cross strut 212 of a formwork panel 2 which belongs to an embodiment of the system according to the invention. FIG. 3 shows the cross struts 212, which are connected to the formwork interface 12 of the connection component 1 in FIG. 2. The cross strut 212 is shown cut in a plane perpendicular to its longitudinal direction. In the representation on the left of the cross strut 212, the formwork skin 22 can also be seen in section and is connected to the framework 21. The formwork skin 22 rests flat here on the side of the cross struts 212 facing left. In the background, a longitudinal strut 211 can be seen in regions and is connected to the cut cross strut 212. In the illustration, the two gripping arms 1211 of the clamping element 121 can also be seen, which are connected to the cross strut 212 in a frictionally engaged and form-fitting manner. The cross strut 212 is formed by a profile tube which has the shape of a bone. An undercut 213, which is designed here as a groove, which extends in the longitudinal direction of the cross strut 212, that is to say in the representation into the plane of the drawing, can be seen on the side of the cross strut 212 pointing upward in the representation. The grooves which form the two undercuts 213 here have an identical, rectangular cross-section. The two undercuts 213 are arranged symmetrically and opposite one another on the cross strut 212. The regions of the gripping arms 1211, which are shown in FIG. 3, are designed identically. The two gripping arms 1211 have a projection 1211a on their tip facing the left in the representation, which projection forms a region here, which in each case engages in one of the undercuts 213. In the embodiment shown, the lower of the two gripping arms 1211 is designed to be movable in a direction parallel to the formwork skin 22, whereby the distance between the two gripping arms 1211 is designed to be adjustable. To produce a connection between the formwork interface 12 and the formwork panel 2, the lower gripping arm is moved vertically downward in the direction symbolized by an arrow in the representation, so that the distance between the two projections 1211a is greater than the width of the cross struts 212 in the vertical direction. Subsequently, the two gripping arms 1211 are pushed partially over the cross struts 212, until the projections 1211a are located adjacent to the two undercuts 213. Subsequently, the lower gripping arm 1211 is moved toward the upper gripping arm 1211 and the distance between the two gripping arms 1211 is reduced. In this case, the two projections 1211a each engage in an undercut 213, whereby a form fit is created. In this state, in which the two projections 1211a already form a form fit with the undercuts 213, the clamping element 121 can be displaced parallel to the running direction of the undercuts 213 along the cross struts 212, as long as the desired relative position between the clamping element 121 and cross strut 212 is reached. Subsequently, the lower gripping arm 1211 is moved toward the upper gripping arm 1211 until the two gripping arms 1211 clamp the cross struts 212. In this state, a force flow is then also present between clamping element 121 and cross struts 212. The described adjustability of the relative position of the clamping element 121 along the undercut 213 is particularly advantageous for a flexible connection between the connection component 1 and the formwork panel 2. Such a connection can also be carried out between a clamping element 121 and a longitudinal strut 211. In the background, an undercut 213 is likewise arranged on the illustrated longitudinal strut 211 and is aligned with the undercuts 213 of the cross strut 212.
[0072] FIG. 4 shows a perspective detailed view of an embodiment of a formwork interface 12 of a connection component 1. The connection component 1 in the embodiment shown in FIG. 4 does not comprise a support element 13. In the embodiment shown, the clamping element 121 of the formwork interface 12 comprises an intermediate post 122 which is formed by a tube portion with a round cross-section. The size and shape of the cross-section of the tube portion of the intermediate post 122 corresponds here to the shape and the size of a vertical post 51 of the frame section 3. The two gripping arms 1211 and the unlocking mechanism 1220 are arranged on the intermediate post 122 and are connected to a cross strut 212 of the formwork panel 2. A frame interface 11 is arranged on the intermediate post 122. The relative position of the frame interface 11 and the intermediate post 122 is adjustable here, wherein at least three possible positions of the frame interface 11 are provided at the intermediate post 122. These three positions can be set by displacing the frame interface 11 on the intermediate post 122 along the longitudinal direction thereof. In the embodiment shown, both the frame interfaces 11 and the intermediate post 122 have bores into which a plug element for plugging the position of the components relative to one another can be introduced. Thus, in the embodiment shown, the position of the frame interface 11 relative to the clamping element 121 is designed to be adjustable. As a result, the connection component 1 can be adapted to different applications in a simple manner. The frame interface 11 is designed here in terms of shape and size identically to an interface which is also inserted within the frame section 3, in particular on a vertical post 51. Elements of the frame section 3, such as a horizontal bar 52 shown in FIG. 4, can thus be connected in the same way to the frame interface 11, such as a connection of different frame elements within the frame section 3. In the embodiment shown in FIG. 4, the clamping element 121 also comprises an unlocking mechanism 1220 by means of which the connection between the gripping arms 1211 and the cross strut 212 can be produced and released again simply and quickly.
[0073] FIG. 5 shows a perspective detailed view of a further embodiment of a formwork interface 12 of a connection component 1. In this embodiment, one of the gripping arms 1211 is formed by a pin element 1212 which is introduced into a recess in a cross strut 212 of the formwork panel 2. In FIG. 5, this pin element 1212 is covered and thus not shown. A corresponding recess, which is suitable for receiving the pin element 1212, is shown on the right-hand side adjacent to the clamping element. Here, the recess forms an undercut 213. In the embodiment shown, the second gripping arm 1211 is formed by a tensioning element 1213. This tensioning element 1213 grips around the cross strut 212 in regions and rests against it. The clamping element 121 further comprises a tensioning mechanism, which here contains a threaded spindle and a handwheel. The relative position between the pin element 1212 and the tensioning element 1213 can be changed by this tensioning mechanism. When the clamping element 121 is attached to the cross strut 212, the pin element 1212 is inserted into the recess and then the clamping mechanism is actuated. As a result, the pin element 1212 and the tensioning mechanism 1213 are moved toward one another and a form-fitting and frictional engagement arises between the clamping element 121 and the cross strut 212. A support element 13 is arranged on the clamping element 121 and the frame interfaces 12. This support element 13 connects the formwork interface 12 to a frame interface 11. The frame interface 11 is designed here as a connection clip 1214 which is connected to a vertical post 51 of the frame section 3. The connection clamp 1214 grips around the vertical post 51 and is fastened to the vertical post with frictional engagement with the aid of a screw connection. The advantage of this embodiment is that the frame interface 11 designed as a connection clip 1214 can be continuously displaced along the vertical post 51 and then positioned with frictional engagement. The relative position of the connection component 1 relative to the frame section 3 can thereby be set very flexibly. It is also possible to arrange a plurality of frame interfaces 11 on the support element 13 if necessary.
[0074] FIG. 6 shows a perspective detailed view of a further embodiment of a formwork interface 12 of a connection component 1. In this embodiment of a connection component 1, the relative position of the formwork interface 12 relative to the frame interface 11 is designed to be adjustable. For this purpose, the formwork interface 12 is designed as a compensating rail 1215. This compensating rail 1215 comprises a first partial region which forms a gripping arm 1211 which is introduced into the undercut 213 in the cross strut 212. This first partial region is hereby formed by two flat irons arranged at an angle to one another, which are connected by a vertically oriented bolt in the representation. This bolt is introduced into a cylindrical recess in the cross strut 212 which forms an undercut 213. The second gripping arm 1211 is not visible in the representation and is formed by a securing pin which is introduced into the vertically oriented bolt on the side which is located below the cross strut 212 in the representation. The compensating rail 1215 further comprises a second partial region which faces right, toward the front in the representation. This second partial region is formed by a rail with a constant cross-section, which in this case has a rectangular cross-section. In this embodiment, the frame interfaces 11 are formed by a clamping clip 1216 which is adjustably connected to the compensating rail 1215. For this purpose, the clamping clip 1216 has a connection region which is designed to be dimensionally complementary in regions to the rail with a constant cross-section of the compensating rail 1215. The connection region grips around the rail with a constant cross-section and is displaceable along the longitudinal axis of the rail with a constant cross-section. The clamping clip 1216 furthermore comprises a bar element which can be introduced into the connection region and which clamps the clamping clip 1216 on the rail with a constant cross-section in the shown state. In this state, the bar element and the connection region completely enclose the rail with a constant cross-section. When the frame interface 11 and formwork interface 12 are connected, the connection region is first displaced relative to the compensating rail 1215, until the desired position of formwork interface 12 and frame interfaces 11 is reached. The bar element is then introduced and this relative position is fixed. The clamping clip 1216 further comprises a connection clip 1214 which is fixedly connected to the connection region. As in the embodiment shown in FIG. 5, the connection clip 1214 is connected in a frictionally engaged manner to a vertical post 51 of the frame section 3. The shown embodiment of a connection component 1 is particularly advantageous since, on the one hand, the relative position between the formwork interface 12 and the frame interface 11 is designed to be adjustable and, on the other hand, the connection clip 1214 of the frame interface 11 can be adjusted continuously in its position relative to a vertical post 51. This embodiment of a connection component 1 thus enables an adaptation of the position between the formwork panel 2 and the frame section 3 in two spatial directions oriented perpendicular to one another.
[0075] The embodiments of a connection component 1 shown in FIG. 4 to FIG. 6 can all be used in a system 100. It is also possible to use a plurality of embodiments of a connection component 1 with one another and combined with one another in a system 100. Furthermore, it is possible in a system 100 alternatively and/or additionally to use one or more connection components 1 according to the embodiments shown in FIGS. 1 and 2. The embodiments shown in FIGS. 1, 2, 4, 5 and 6 can thus be used in any way combined with one another in a system 100 according to the invention, whereby a very high flexibility with respect to the type and the position of the connection between a formwork panel 2 and a frame section 3 is made possible.
[0076] FIG. 7 shows a perspective representation of a first state when carrying out a method according to the invention. In FIGS. 7 to 9, states occurring in chronological succession are shown, which occur in a method for producing a wall element using a system 100 according to the invention. In FIG. 7, an adjustable formwork was already set up according to method step A) and is located to the rear left in the representation. The adjustable formwork corresponds to the prior art and is constructed from a plurality of formwork panels 2 which are connected to one another. The adjustable formwork is held in its vertically oriented position by at least one support M. Opposite the formwork skin of the adjustable formwork, a system was constructed in parallel with the adjustable formwork according to method step B). The system 100 here comprises a total of twelve formwork panels 2 which are joined together to form a common formwork. The formwork panels 2 are connected to a frame section 3 via a plurality of connection components 1, which are covered in the representation. The frame section 3 points toward the adjustable formwork and is oriented parallel to its formwork skin. There is a distance between the adjustable formwork and the frame section 3, which distance corresponds approximately to the thickness of the wall element to be produced. In the state shown in FIG. 7, a reinforcement B was also already attached to the adjustable formwork. The reinforcement B is hereby formed by a plurality of iron mats. The reinforcement B was attached and fastened by persons working from the frame section 3. The frame section 3 with its three tread levels arranged one above the other is designed such that the entire surface of the adjustable formwork can be conveniently reached by workers. A reinforcement can thus be easily and quickly attached from the frame section 3. In the state shown in FIG. 7, the reinforcement B is already attached completely to the adjustable formwork and the workers have left the frame section 3. In the next step, the system 100 is rotated about a vertically oriented imaginary axis VA in order to orient the formwork skin 22 of the formwork panels 2 of the system 100 toward the front right in FIG. 7 toward the adjustable formwork and toward the reinforcement B. For this rotation, the entire system can be raised by a crane and rotated in the state hanging from the crane. The system 100 is rotated according to the arrow P shown on the right next to the system 100.
[0077] FIG. 8 shows a perspective representation of a second state when a method according to the invention is carried out. FIG. 8 shows a state which occurs during the rotation of the system 100 according to method step D). Starting from the state shown in FIG. 7, the system 100 was already rotated by an angle of approximately 120? about the imaginary, vertically oriented axis VA. In the state shown in FIG. 8, the frame section 3, which also points toward the adjustable formwork in FIG. 7, already points away from the adjustable formwork. Starting from the state shown in FIG. 8, the rotation of the system about the axis VA is continued in the direction of the arrow P until the formwork panels 2 of the system 100 are aligned parallel to the adjustable formwork and the formwork skin 22 of the frame system 100 points toward the reinforcement B and toward the adjustable formwork. Overall, the system 100 is rotated by 180?. This rotation according to method step D) enables a very rapid construction of a closing formwork which is formed by the same system 100 which previously served with its frame section 3 for fastening the reinforcement B. The system is simply rotated through 180? with the aid of a crane and set up parallel to the adjustable formwork. The formwork is thus already fully constructed and the adjustable formwork and the system together delimit the spatial region in which the wall element is to be produced. A further advantage is that after the rotation through 180?, the frame section 3 is still connected to the formwork panels 2 of the system 100. After rotation, the filling of a liquid concrete material according to method step E) from the frame section 3 can thus be started directly with the preparation of the formwork. In this preparation of the formwork, for example, anchors can be arranged between the system and the adjustable formwork and connect the two parts of the formwork to one another and hold the two parts of the formwork together during filling of the concrete material and take up forces. The work for preparing the formwork can again be carried out by persons located on the frame section 3, who from there can easily reach any point of the formwork. The rotation according to method step D) thus eliminates the degradation of a reinforcement framework which has to be used according to the prior art for attaching the reinforcement to the adjustable formwork. In addition, the construction of a working frame or a working platform for preparing the formwork is dispensed with after the installation of the system 100 as a closing formwork, since the frame section 3 is already connected to the formwork panels 2.
[0078] FIG. 9 shows a perspective representation of a third state when carrying out a method according to the invention. Before the state shown in FIG. 9, liquid material, in particular concrete material, was filled into the formwork according to method step F) after preparation of the formwork according to method step E). The reinforcement B was enclosed in the concrete material. The formwork can also be filled by persons located on the frame section 3. Furthermore, the filling of the formwork from the frame section 3 can be monitored conveniently. Furthermore, before the state shown in FIG. 9, the filled material was cured in the formwork according to method step G), whereby the wall element W was formed, which consists of the cured concrete material and the reinforcement B. The curing of the concrete material can also be monitored from the frame section 3. In the state shown in FIG. 9, the adjustable formwork and the system 100 are removed from the wall element W produced. In the illustration, the adjustable formwork and the system 100 are shown in parallel offset away from the wall element W. However, the adjustable formwork and the system can also be lifted upwards with the aid of a crane. After the production of this wall element W, the system can be used without further conversion work directly for attaching a further reinforcement B to a further adjustable formwork, analogously to the state shown in FIG. 7. For example, the system 100 can simply be rotated back again about the imaginary vertically oriented axis VA by a crane and can be positioned at a different location on the construction site. The system can thus be used again without interruptions to produce a further wall element. The production of a wall element is thereby simplified, since significantly less effort is required for the construction and disassembly of formwork and frames. This also reduces the time which is required to produce a wall element W.
