Description

System for shuttering a wall element with a free-standing scaffold section

The present application claims the priority of German Patent Application No. 10 2021 120 438.0, the content of which is incorporated herein by reference in its entirety.

The invention relates to a system for shuttering a wall element, comprising at least one formwork panel, at least one connecting component and at least one scaffolding section, the connecting component comprising at least one scaffolding interface which is provided for detachable connection to one scaffolding section and at least one formwork interface which is intended for detachable connection with the switchboard is provided. In this case, the at least one connecting component is connected to the scaffolding section with its scaffolding interface and the connecting component is connected to the at least one formwork panel with its formwork interface. The connection between the connecting component and the formwork panel and/or the connection between the connecting component and the scaffolding section is designed to be detachable when the system is assembled and the scaffolding section can be separated from the formwork panel, with the scaffolding section being usable as a free-standing scaffolding section after it has been separated from the formwork panel is. The invention further relates to a method for producing a wall element using such a system.

The invention relates to the field of construction. When erecting or remodeling buildings, building parts are often formed by pouring concrete. The shape of these cast building parts is specified by a formwork, the formwork being erected on the construction site before the casting. In particular, ceilings or walls of a building are erected with the help of circuits. When constructing high walls or wall elements, scaffolding is required in order to be able to prepare the formwork for the manufacture of the wall element. On the one hand, scaffolding is required to connect individual formwork panels to form the overall formwork, for example by attaching formwork locks. Furthermore, before the production of a wall element, two opposing formwork panels must be connected to one another by means of anchors in order to absorb the outward pressure of the cast-in concrete material. For this purpose, the formwork panels must be accessible to workers over their entire height, which is usually done using scaffolding or a working platform. Furthermore, in most cases, before the wall element is produced, reinforcement must be attached to an already positioned formwork or between such a formwork and a closing formwork which is opposite the formwork. According to the state of the art, scaffolding or working platforms that are provided for attaching formwork locks are arranged on the formwork in such a way that no reinforcement can be attached to these scaffolding or working platforms. The places where the reinforcement must be positioned are simply not accessible from these scaffolding or work platforms used to prepare the formwork panels, since they are on the opposite side of the formwork panel. In practice, this means that a first type of scaffolding is required to operate the formwork and a second type of scaffolding is required to position and insert the reinforcement into the formwork. In addition, there are usually a large number of different types of scaffolding and formwork panels on the construction site, which means that the scaffolding can be connected to the formwork panels, especially for the applications described above, is often not given. Differences in the grid, which exist between the scaffolding systems and the formwork systems, usually prove to be problematic. Finally, in many applications, after the casting of a wall element using the formwork, work must still be carried out on the wall element after the formwork has been removed, for example the filling of anchor holes or plastering or painting work. In order to be able to reach the wall element over its entire height, scaffolding or a work platform is required again after the actual casting in order to be able to carry out the final work. A large number of different scaffolding or work platforms are therefore required for the production of a wall element using formwork, which leads to complicated work processes and the need for a large number of different scaffolding elements.

The object of the invention is therefore to propose solutions with which the production of a wall element can be simplified.

This object of the invention is achieved by a system for forming a wall element, comprising at least one formwork panel, at least one connecting component and at least one scaffolding section,

- wherein the scaffolding section comprises several vertical standards and several horizontal bars and the scaffolding section extends in three spatial directions,

- wherein the formwork panel comprises a frame and a formwork skin, the frame having a plurality of longitudinal struts and a plurality of transverse struts, the longitudinal struts and the transverse struts being arranged essentially perpendicularly to one another and the formwork skin being detachably attachable to the frame, with the Formlining rests on at least part of the longitudinal struts and the transverse struts, with at least part of the longitudinal struts and/or transverse struts having an undercut which is oriented in the longitudinal direction of the longitudinal struts and/or transverse struts, with the undercut for the positive and non-positive connection with the formwork interface a connecting component is provided,

- wherein the connecting component comprises at least one scaffolding interface, which is provided for the detachable connection to the scaffolding section and at least one formwork interface, which is provided for detachable connection to the formwork panel, wherein the formwork interface comprises at least one clamping element and the clamping element comprises at least two gripping arms, with at least one of the gripping arms is designed to be movable relative to another gripping arm, with the distance between the at least two gripping arms being designed to be adjustable, with the at least one connecting component being connected to the frame section with its frame interface, with the gripping arms of the clamping element fitting at least in regions into the undercut on the frame of the Formwork panel engage, whereby at least one positive, preferably also a non-positive, connection between the formwork interface and the formwork panel is present, this connection along the undercut can be positioned as desired, whereby the relative position between the connecting component and the formwork panel is adjustable in a direction parallel to the direction of the undercut, and the connection component is connected with its formwork interface to the at least one formwork panel, the connection between the connection component and the formwork panel and/or the connection between the connection component and the scaffolding section being designed to be detachable when the system is in the assembled state, and the scaffolding section can therefore be separated from the formwork panel , wherein the scaffold section can be used as a free-standing scaffold section after separation from the formwork panel.

The system according to the invention comprises at least one formwork panel, at least one scaffolding section and at least one connecting component which connects the formwork panel to the scaffolding section. A connection, in particular a statically load-bearing connection, between the formwork panel and the scaffolding section is possible by means of the connecting component. The formwork panel and the scaffolding section can be connected to one another in a simple manner by the connecting component, with the connection and also the disconnection of this connection being able to be carried out easily and quickly. A system according to the invention usually comprises several formwork panels and can also comprise more than one scaffolding section. A plurality of connecting components are usually provided for the connection, which are arranged in different positions between the formwork panel or formwork panels and the scaffolding section.

The scaffolding section of the system according to the invention is formed by a scaffolding section according to the prior art and comprises several vertical standards which are essentially vertically oriented in the assembled state and several horizontal bars which are essentially horizontally oriented in the assembled state. These elements of the framework section are connected to one another and, when assembled, form a framework section extending in three spatial directions. The truss section may include other elements such as treads, ladders, railings and the like. The skeleton section is preferably constructed in a modular manner, which means that the skeleton section can be constructed from standard elements of different sizes and shapes. The framework section can be what is known as a system framework, for example.

The system according to the invention also comprises at least one formwork panel with a supporting frame and a formwork panel which is detachably connected to the frame. The frame is preferably constructed in the form of a lattice, with several longitudinal struts, which are oriented essentially vertically when assembled, and several transverse struts, which are oriented essentially horizontally when assembled, forming this frame. The longitudinal struts and the transverse struts are oriented at right angles to one another. The formwork skin is fastened to the frame and rests on at least part of the longitudinal struts and transverse struts. During the manufacture of a wall element, this contact forces forces that act on the formwork skin from the concrete material and are diverted into the load-bearing frame of the formwork panel. At least part of the longitudinal struts and/or the transverse struts has an undercut. An undercut is to be understood as meaning an area which is set back in relation to neighboring areas. If a counter-element is connected to the frame of the formwork panel in such a way that it engages in the undercut in some areas, a form fit is created, by which the counter-element is connected to the frame. The undercut is intended to enter into a positive and non-positive connection with a formwork interface of a connecting component, which later is described. The undercut extends in the longitudinal direction of the longitudinal struts and/or transverse struts. For example, the undercut can be formed by a groove which is set back from the remaining surface of the longitudinal struts and/or transverse struts and which extends along these struts. This extension of the undercut in the longitudinal direction means that a connecting component can be fastened steplessly at different positions on the frame of the formlining. This variability with regard to the position at which a connecting component can be connected to the frame means that formwork panels and scaffolding sections with different grids can be connected to one another very easily. Due to the undercut extending in the longitudinal direction, a connection can be made at virtually any position, which means that the grid used in the formwork panel or in the formwork system between several formwork panels is irrelevant for the connection to the connecting component. Preferred embodiments of the undercut will be described later.

The system according to the invention also includes at least one connection component with a framework interface and a formwork interface. The formwork interface is intended for connection to the formwork panel, in particular to the frame of the formwork panel. For this purpose, the formwork interface comprises at least one clamping element, which in turn comprises at least two gripping arms. These gripping arms are designed to be movable in relation to one another. The distance between one gripper arm and the other gripper arm is variable or adjustable. The gripping arms of the clamping element are intended to engage at least in certain areas in the undercut in the frame of the formwork panel and thus produce a form-fitting connection between the connecting component and the formwork panel. In addition to the gripping arms, the clamping element can have other elements, for example a mechanism for actuating and locking the gripping arms. The connection between the connecting component and the frame of the formwork panel is established in that the two gripping arms are initially adjusted in such a way that they can partially grip a transverse strut or a longitudinal strut of the frame. In this condition, the gripping arms are partially slid over the longitudinal strut or the transverse strut until a portion of the gripping arms are positioned adjacent one or more undercuts on the transverse strut or the longitudinal strut. The distance between the two gripping arms is then reduced, with these engaging at least in certain areas in the undercut on the frame. This creates the form fit described above between the connecting component and the frame of the formwork panel. With this connection, a non-positive connection, in particular a clamp, is preferably produced at the same time between the gripping arms and the frame. Such a non-positive connection ensures that there is no play between the connecting component and the formwork panel and thus a stable, statically and dynamically loadable connection is created. What is particularly advantageous about this connection is that it can be produced at different positions in the longitudinal direction of the transverse strut or the longitudinal strut. Thus, the connecting component can be variably positioned relative to the frame of the formwork panel. The undercut advantageously extends over the entire free length of the transverse struts and the longitudinal struts. As a result, a connection can be made to the connecting component at almost all locations on the frame of the formwork panel. Such a connection is only not possible at the crossing points of the longitudinal struts with the transverse struts, or only possible by using an additional component. The Connection between the connecting member and the formwork panel via the clamp member is designed so that it can be easily disconnected even in a state where the formwork panel and the skeleton section are assembled and used to manufacture a wall panel. In the system according to the invention, the connection component can therefore be detached from the formwork panel and/or the connection component from the scaffolding section in the assembled state. This has the advantage that the scaffolding section can be separated from the formwork panel in the assembled state during the manufacture of a wall element. Such separability results in advantages in the manufacture of the wall element. For example, one and the same scaffold section can be used for different tasks in the manufacture of the wall element. The scaffolding section of a system according to the invention is designed in such a way that it can be used as a free-standing scaffolding section after it has been separated from the formwork panel, during which the connecting component is preferably also removed. This means that the scaffolding section itself is stable and stable on the ground and can be used by working people as a scaffolding section. The scaffolding section can be connected to the formwork panel by the connecting component, for example in order to transport or position the two components together in the connected state. However, after the scaffold section and formwork panel have been separated, the scaffold section can be used like a known scaffold section. Furthermore, it is possible that in a system according to the invention, after a previous separation of formwork panel and scaffolding section, a new connection is established between the two components. For this purpose, at least one connecting component is simply brought into connection with both the formwork panel and the scaffolding section.

The system according to the invention makes it possible to connect different types or systems of formwork panel and scaffolding section. In particular, the connection between the formwork interface of the connecting component and the frame of the formwork panel, which can be infinitely adjusted in terms of its position, enables a simple and flexible connection. A plurality of connecting components attached at different positions are preferably provided for connecting a formwork panel to a scaffolding section. The framework interface of the connection component is preferably designed in such a way that it is compatible with a connection interface used within the framework section. In this way, the connection component can be easily combined with different types of frame sections by varying or adapting the frame interface. The connecting component has a simple structure, as a result of which a system according to the invention can be provided simply and cost-effectively, which uses an already existing scaffolding section. Existing equipment can thus advantageously be converted to a system according to the invention. The fact that the formwork panel and scaffolding section can be easily separated, which is brought about by the connection component with its formwork interface and its scaffolding interface, offers a number of advantages when producing a wall element. The scaffolding section can be used for several tasks, for example to attach reinforcement to or in the formwork, to safely pour the concrete material into the formwork and, after removing the formwork panel, for finishing work on the wall element that has already been cast. A system according to the invention thus saves effort and working time in the production of a wall element, which is brought about by the multiple use of a single scaffolding section. The The system according to the invention is therefore particularly suitable for the production of a wall element. In addition, the system according to the invention can of course also be used to produce other building elements, such as pillars or columns.

In one embodiment of the system, it is provided that the clamping element is designed to be complementary in shape to an element of the formwork panel, at least in certain areas. Shape-complementary is to be understood here that a region of the clamping element, in particular the tip region of the gripping arms, has a negative shape for the undercut on the frame of the formwork panel. This ensures a secure form fit between the formwork interface and the formwork panel.

Furthermore, it is provided that the frame interface is designed to be complementary in shape to an interface on the frame section, at least in some areas. Shape-complementary is to be understood here as meaning that at least a partial area of the frame interface has a negative shape to a partial area at an interface on the frame section. The scaffolding section has interfaces for connecting its components, for example vertical standards and horizontal bars. A partial area of the frame interface of the connecting component is preferably designed to be similar or identical in shape and size to an interface which is also used in the frame section. For example, connecting disks with recesses can be arranged on a vertical post of the scaffolding section, into which interface elements of a horizontal ledger can be introduced in a form-fitting manner. In this case, the framework interface of the connection component can be designed in accordance with the interface on the horizontal bar. In this way, the scaffolding interface can be connected to a vertical standard in the same way as a horizontal ledger of the scaffolding section. With this embodiment, the connection component can be fastened in different positions on the framework section in a simple manner.

In an advantageous embodiment, it is provided that a support element is provided which is connected to the formwork interface and the scaffolding interface, in particular wherein the support element is rod-shaped, with the formwork interface and the scaffolding interface being arranged on the support element at a distance from one another. In this embodiment, a support element is provided which connects the formwork interface and the framework interface to one another. The support element can have different shapes. The support element is preferably designed in the form of a rod and can be formed, for example, by a tube or a tube section. The distance between the formwork panel and the scaffolding section can be adjusted when the system is assembled due to the distance at which the formwork interface and the scaffolding interface are arranged relative to one another on the support element. In order to be able to adjust the distance between the formwork panel and the scaffolding section individually, the support element can also be designed to be adjustable in length, for example telescopic. The scaffolding interface and the formwork interface can be rigidly connected to the support element or their position and orientation can be adjusted. It is preferably provided that the support element has a longitudinal axis and the formwork interface and the framework interface are spaced apart from one another along the longitudinal axis and the longitudinal axis is oriented essentially parallel to the surface of the formlining or essentially perpendicular to the surface of the formlining. In this embodiment, the support element has a longitudinal axis which runs between the formwork interface and the framework interface. The connection component is preferably oriented in relation to the formwork panel in such a way that the longitudinal axis runs essentially parallel to the surface of the formwork skin or essentially perpendicularly to the surface of the formwork skin. However, the orientation of the longitudinal axis relative to the surface of the formlining can also be at a different angle.

It is advantageously provided that a compensating element is provided, which is arranged between the support element and the scaffold interface, the compensating element having a linear bearing, by means of which the scaffold interface and the support element can be displaced relative to the support element, at least in regions, in a direction parallel to the longitudinal axis of the support element . In this embodiment, a compensating element is provided, which allows a shift between the scaffold interface and the support element and thus also a shift between the scaffold interface and the formwork interface. For this purpose, the compensating element has a linear bearing, which performs a linear movement in a direction parallel to the longitudinal axis of the support element. This ability to move between the scaffolding interface at the formwork interface further increases the flexibility in the connection between the formlining and the scaffolding section. Because it can be moved, the distance between the two interfaces can be continuously adjusted, which means that tolerance differences or grid differences between the scaffolding section and the formwork panel can be compensated for. In addition, the compensating element also enables the compensation of height differences in the subsurface of the system. For example, if the ground under the formwork panel is higher than the ground under the scaffolding section, this difference in height can be continuously compensated for using the compensation element, without the need for adjustment work on the system.

Furthermore, it is provided that the distance between the framework interface and the formwork interface, in particular in a direction perpendicular to the longitudinal axis of the support element, is greater than or equal to the thickness of the formwork panel. The distance between the scaffolding interface and the formwork interface defines the distance between the formwork panel and the scaffolding section. The distance between the two interfaces is preferably greater than the thickness of the formwork panel in a direction perpendicular to the surface of the formwork skin. However, this distance can also be smaller. In addition, the distance can also be chosen to be significantly larger, for example the distance between the scaffolding interface and the formwork interface, in particular in a direction perpendicular to the longitudinal axis of the support element, can also be greater than three times the thickness of the formwork panel, or greater than five times the thickness of the be switchboard.

In a further embodiment it is provided that two scaffolding interfaces and two formwork interfaces are provided, which are each spaced apart from one another on a common Supporting element are arranged. In this embodiment, two scaffolding interfaces and two formwork interfaces are arranged on a support element. In this embodiment, the length along the longitudinal direction of the support member is longer than in the previously described embodiments. In this embodiment, the support element is arranged with its longitudinal direction parallel to a vertical post of the scaffold section in the system. The length of the support element is at least 1 m. Two scaffold interfaces are arranged on the support element pointing in a first direction, which are connected or are connected to interfaces on the scaffold section. Two formwork interfaces are also arranged on an opposite second side, which are connected or are connected to the frame of the formwork panel. Such a connecting component enables a two-point connection to the formwork panel and to the scaffolding section. The connection component is thus more stable and more load-bearing. Furthermore, the number of components required to set up a system is reduced by such a connecting component, as a result of which the logistics on the construction site can be simplified and the set-up time of the system can be reduced.

Cleverly, it is provided that the clamping element of the two formwork interfaces, which are arranged on a common support element, has an unlocking mechanism, which can be actuated by a simple linear or rotational movement, whereby the positive locking between the formwork interface and the formwork panel can be canceled by actuating the unlocking mechanism is. In this embodiment, the clamping element has an unlocking mechanism which can be operated quickly and easily by hand. As a result, the formwork interface of the connecting component can be separated from the formwork panel quickly and easily. This is advantageous if the formwork panel is to be separated from the scaffolding section during the production of a wall element when the system is in the dismantled state. Such a separation can be carried out quickly and easily using the unlocking mechanism. The unlocking mechanism can be actuated by a simple movement, which can be linear, rotary or a simple combination of both types of movement. For example, the unlocking mechanism can have a rod-shaped lever, which is actuated in a linear movement or a rotational movement, thereby breaking the form fit between the formwork interface and the formwork panel. In order to prevent the unlocking mechanism from being actuated accidentally, a safety mechanism can be provided which must first be deactivated before the unlocking mechanism is actuated. Such an unlocking mechanism is preferably used in a connection component which has two or more formwork interfaces. Such a connection component is described in the previous embodiment. It can be provided that a common unlocking mechanism is provided for several formwork interfaces or each formwork interface has its own unlocking mechanism, with the unlocking mechanisms being coupled to one another. In this way, several formwork interfaces can be separated from the formwork panel at the same time with a single operation. This further reduces the time required to separate the formwork panel and scaffolding section. Of course, it is also possible to provide an unlocking mechanism in embodiments of a connection component which only has one formwork interface. In a further embodiment it is provided that the direction of movement of at least one of the gripping arms of the clamping element is oriented essentially parallel to the connection direction of the scaffolding interface and/or essentially parallel to the surface of the formlining. The distance between the two gripping arms of the clamping element is adjustable, with at least one of the gripping arms being designed to be movable. In one embodiment, at least one of these gripping arms can be moved in a direction which, when the system is in the dismantled state, runs essentially parallel to the surface of the formlining. In this way, the movement of the gripping arm can at least partially grip a longitudinal strut or a transverse strut of the frame of the formwork panel. The direction of movement of the gripper arm is to be understood as meaning the direction along which the distance between the two gripper arms is adjustable. The clamping element can also be designed so that both gripping arms are designed to be movable. The direction of movement of the gripper arm preferably runs parallel to a direction of connection of the scaffold interface. This connection direction is the direction in which the truss interface is moved to make or break a connection with the truss section. In this case, the connection direction can be oriented parallel to a vertical post of the scaffolding section, that is to say essentially vertically when the system is in the assembled state. In this case, the direction of movement of the gripping arm is also essentially vertical, as a result of which it is possible for the clamping element to grip around a transverse strut of the formwork panel.

In an alternative embodiment, it is provided that the direction of movement of at least one of the gripping arms of the clamping element is oriented essentially perpendicularly to the direction of connection of the scaffolding interface and/or perpendicularly to the surface of the formlining. In this embodiment, the direction of movement of a gripping arm is oriented perpendicularly to the direction of movement in the embodiment described above. The direction of movement of at least one of the gripper arms runs perpendicularly to the surface of the formlining. This makes it possible for the clamping element to enclose an edge area of the frame of the formwork panel. This enables the connecting component to be arranged at the edge of the formwork panel, which makes it possible, for example, to arrange a second formwork panel between the formwork panel and the scaffolding section. When the system is set up, the direction of movement preferably runs in the horizontal direction. The direction of movement is thus oriented essentially perpendicularly to a connection direction of the frame interface, which preferably runs in the vertical direction.

It is cleverly provided that the length of the support element is designed to be adjustable. In this embodiment, the distance between the scaffold section and the formwork panel can be varied by adjusting the support element. This is particularly advantageous when objects with different thicknesses, for example wall elements to be produced, are to be arranged between the scaffolding section and the formwork panel. For this purpose, the support element can be designed to be telescopic. The support element can also have at least one locking device with which a set length of the support element can be stably fixed. In an advantageous embodiment it is provided that the undercut on the frame of the formwork panel is designed as a groove which is oriented in the longitudinal direction of the longitudinal struts and/or transverse struts, the groove having a U-shaped, rectangular or curved cross section. The undercut can be designed as a groove which is introduced into the longitudinal struts and/or transverse struts and which extends, at least in regions, along these struts. The longitudinal struts and the transverse struts preferably have a rectangular cross section, with the formwork facing lying on a side surface of this rectangular cross section. The undercut is preferably arranged on a side surface which is adjacent to the side surface on which the formwork skin rests. Two undercuts can also be arranged on a transverse strut or longitudinal strut, which are preferably arranged on two opposite side faces of the struts. In cross section, such an undercut designed as a groove can have a U-shaped, rectangular, polygonal or semi-circular shape. In general, the most varied of shapes are suitable for the cross section of the groove, as long as these cross sections create an undercut in relation to the adjacent areas on the transverse strut or the longitudinal strut.

In a further embodiment it is provided that at least two connection components are provided and each connection component has at least two formwork interfaces and the formwork panel has a plurality of transverse struts with an undercut arranged thereon at least in some areas, the distance between the at least two formwork interfaces on the connection component being an integral multiple of the distance between corresponds to two adjacent cross braces of the formwork panel. In this embodiment, the grids of the formwork panel and the connecting component are matched to one another, so that the components of the system can be used flexibly. Each connecting component has two formwork interfaces, which are arranged at a distance from one another on a support element. The distance between the two formwork interfaces on the support element corresponds to an integer multiple of the distance between two cross braces of the formwork panel. The distance between two adjacent cross braces of the formwork panel is less than the distance between the two formwork interfaces on the connecting component. This choice of dimensions allows the connection component to be connected to different cross braces of the formwork panel at different positions. In the assembled state of the system, the connecting component can thus be arranged at different heights in the vertical direction relative to the formwork panel. Such a variability of the connection position between the connection component and the formwork panel is particularly useful when several formwork panels are combined with one another and used as formwork for a wall element. In the areas of the combined formwork where two formwork panels meet, it may not be possible to attach the formwork interface. In this case, the connection to the connecting component can be offset from the points at which two formwork panels meet. Thus, a connection of a scaffolding section to a formwork panel by the connecting component is also possible if the overall size or overall shape of the formwork and/or the scaffolding section is varied.

It is advantageously provided that the formwork panel and the scaffolding section are oriented parallel to one another, with the distance between the formwork panel and the scaffolding section being Connection component is determined. Such a parallel arrangement of formwork panel and scaffolding section is particularly advantageous in the production of a wall element, since the formwork or the wall element is always located at a constant distance from the scaffolding. However, it is of course also possible to arrange the formwork panel and scaffolding section at a different angle to one another, for example if the wall element to be produced has an irregular or angled shape.

Furthermore, it is advantageously provided that the clamping element comprises a spigot element and a clamping element, with the spigot element being introduced in a form-fitting manner into a recess, in particular into a bore, in one of the longitudinal struts or the transverse struts of the formwork panel and the clamping element being designed to be movable relative to the spigot element and the clamping element rests at least in regions on one of the longitudinal struts or the transverse struts, with a clamping mechanism being provided which generates the relative movement between the pin element and the clamping element and with the clamping mechanism generating a positive and non-positive connection between the connecting component and the frame of the formwork panel. In this embodiment, the undercut on the frame of the formwork panel is formed by a recess or a groove in a transverse strut or a longitudinal strut. A pin element is provided on the clamping element, which is introduced in a form-fitting manner into the recess on the frame during the connection. In some areas, the pin element has a negative shape for the recess and forms a movable gripping arm of the clamping element. In this embodiment, the second gripping arm is formed by a clamping element which, when connected to the frame, bears against a longitudinal strut or a transverse strut and partially encloses it. A clamping mechanism is arranged between the pin element and the clamping element, which produces a relative movement between the two elements or gripping arms. By actuating the tensioning mechanism, the distance between the spigot element and the tensioning element is reduced, as a result of which a flow of forces and a positive connection are produced between the framework interface and the frame of the formwork panel.

It is cleverly provided that the scaffolding interface, which is arranged at a distance from the formwork interface on a support element, is designed as a connecting clamp, with the connecting clamp being non-positively fastened to a vertical post of the scaffolding section. In this embodiment, the scaffolding interface is designed as a connecting clamp, which is connected to a vertical post of the scaffolding section in a force-fitting and form-fitting manner. This connection point can be positioned almost anywhere on the vertical post. In this embodiment, the framework interface is therefore not identical to an interface that is used to connect components within the framework section. The connection clamp encloses a vertical post in the circumferential direction and is clamped at the desired connection position, for example using a screw connection. A scaffold interface designed as a connecting clip has the advantage that it can be used particularly flexibly with regard to the relative position between the connecting component and scaffold section. Thus, in this embodiment, it is also possible to compensate for tolerances or different heights of the subsoil under the formwork panel and the scaffolding section between the connecting component and the scaffolding section. In an alternative embodiment, it is provided that the formwork interface is formed by a compensating rail and the scaffolding interface is formed by a clamp, with the compensating rail having a first section, which forms a gripping arm, being introduced into the undercut in the frame of the formwork panel, with the second gripping arm being inserted through a locking pin is formed, which can be introduced into the first subarea and the compensating rail has a second subarea, which is designed as a rail with a constant cross-section and the clamp has a connection area which is designed at least partially in a form complementary to the compensating rail and the clamp also has a locking element , which can be introduced into the connection area and in the connected state the connection area and the locking element together completely enclose the compensation rail, with the clamp parallel to the longitudinal direction of the compensation Rail is designed to be displaceable and the clamp also has a connecting clip, which is arranged adjacent to the connection area, wherein the connecting clip is non-positively attached to a vertical post of the scaffolding section. In this embodiment, the formwork interface is designed as a compensating rail. A formwork interface designed in this way comprises a first partial area which is introduced in a form-fitting manner into an undercut in the frame and which forms a first gripping arm. In this embodiment, the undercut penetrates a longitudinal strut or a transverse strut in the frame and the first partial area is introduced into the undercut in such a way that it penetrates the entire longitudinal strut or transverse strut. In this embodiment, a securing pin is provided as the second gripping arm, which can be introduced into the first partial area. When connecting, the first section is guided through the undercut in the frame and then the locking pin is inserted into the part that protrudes beyond the longitudinal strut or the transverse strut. In this way, the formwork interface is positively connected to the frame of the formwork panel. Adjacent to the first section, the compensating rail has a second section, which is designed as a rail with a constant cross section. This rail is then used to connect to the scaffold interface, which is designed as a clamp. The provision of the second section as a rail with a constant cross-section improves flexibility with regard to the relative position between the formwork panel and the framework section. Using this rail with a constant cross-section, the relative position between the formwork interface and the scaffolding interface in the connection component can be varied along the length of this rail. Thus, in this embodiment, there is not only variability with regard to the attachment of the connecting component to the formwork panel and to the scaffolding section, but there is also additional variability or adjustability within the connecting component. This embodiment is particularly favorable if the formwork panel has undercuts on its frame only at discrete points. Such formwork panels often exist in the inventory of construction companies and should continue to be used in the future. Such formwork panels from older stock can be used very flexibly in a system with a connecting component according to this embodiment. The adjustability of the scaffolding interface relative to the formwork interface is also made possible by the connection area of the clamp, which in this embodiment forms the scaffolding interface. This connection area is at least partially designed to be complementary in shape to the second subarea of the compensating rail. This means that the connection area encompasses a partial area of the compensating rail. The clamping point also has a fixed connection between the scaffolding interface and the formwork interface a locking element, which can be introduced into the connection area and, together with the connection area, completely surrounds the rail with a constant cross-section when connected. The locking element is designed in such a way that a non-positive connection can also be established between the clamping point and the compensating rail. When connecting, the connection area is first pushed over the second section of the compensating rail. In this state, the connection area can be displaced relative to the compensating rail along the length of the rail with a constant cross-section, as a result of which the position between the formwork interface and the scaffolding interface can be adjusted. The locking element is then introduced into the connection area, creating a form fit and a force fit between the components. The connection component is then fixed in this state. The connection of the scaffolding interface to the scaffolding section takes place, as in the previously described embodiment, via a connecting clamp which, in the connected state, encloses a vertical post of the scaffolding section and is non-positively fastened to it. As described above, this connection clamp is advantageous here, since it can be positioned almost steplessly relative to a vertical post of the scaffolding section. The embodiment described thus has a very high degree of adaptability with regard to the shape and the positioning of the connecting component between the formwork panel and the scaffolding section.

The object of the invention is further achieved by a method for producing a wall element comprising the steps

A) Setting up a formwork, which comprises at least one formwork panel,

B) Fastening of reinforcement to the erected formwork,

C) erection of a closing formwork, wherein the setting formwork and the closing formwork delimit the spatial area in which the wall element is provided and wherein the reinforcement is arranged between the setting formwork and the closing formwork, and wherein the closing formwork is formed by a system according to one of the previously described embodiments, whose formwork panel is oriented towards the reinforcement and the scaffolding section of the system is arranged on the opposite side of the formwork panel to the formwork,

D) Preparation of the formwork for the filling of a liquid material between the initial formwork and the closing formwork, with anchors being introduced in particular, which connect the initial formwork and the closing formwork to one another,

E) filling the formwork with a liquid material,

F) hardening of the material, whereby it forms the wall element together with the reinforcement,

G) separation of the formwork panel from the scaffolding section, whereby the scaffolding interface of the connecting component is detached from the scaffolding section or the formwork interface of the connecting component is detached from the formwork panel,

H) removing the formwork panel, leaving the scaffolding section in an unchanged position,

I) Machining of the cast wall element from the framework section.

The method according to the invention can be carried out to produce a wall element of a building. However, this method is also suitable for the production of other building elements, such as for example columns or pillars. The process is preferably carried out in the specified order of process steps A) to I). However, it is also possible to change the order of the method steps.

In a first method step, a formwork is set up, which comprises at least one formwork panel. The term formwork is to be understood as meaning a formwork which is erected as the first part of the formwork before the erection of a wall element. The formwork is usually set up on the ground on which the wall element is to be built. In order to secure the temporary formwork from falling over, it preferably has a support which, when erected, is arranged on the side of the temporary formwork which points away from the wall element to be erected. The setting formwork preferably comprises a plurality of formwork panels connected to one another. Method step A) is completed as soon as the entire formwork has been erected and thus positioned.

In a second method step B), reinforcement is arranged and fastened on or in front of the formwork. The reinforcement serves to reinforce the wall element to be erected and can consist of iron mats, for example. In the case of high wall elements, scaffolding or a working platform is required to attach the reinforcement to the formwork. The reinforcement is preferably positioned and fastened to the setting formwork by fastening elements such as wire.

After the reinforcement has been arranged, as a third method step C) a closing formwork is set up opposite the setting formwork. According to the invention, this closure formwork is formed by a system according to one of the embodiments described above. The system forming the closing formwork is set up in such a way that the formwork skin of the formwork panel of the system faces the reinforcement and the main formwork. In the dismantled state, the setting formwork and the formwork panel of the closing formwork then delimit the spatial area in which the wall element is to be created. The reinforcement is also arranged between the main formwork and the closing formwork. The system, comprising at least one formwork panel, at least one connecting component and at least one skeleton section, is assembled, with the skeleton section being arranged on the side of the formwork panel of the system facing away from the setting formwork. In this way, a formwork is created which is formed on the one hand by the setting formwork and on the other hand by the closing formwork formed by the system. The framework section is arranged outside of the spatial area in which the wall element is to be created. At the end of process step C), all components are fixed. The scaffolding section, which is connected to the formwork panel of the system, can then be entered by workers and used to carry out work.

In a fourth method step D), the formwork, consisting of the setting formwork and the formwork panel of the closing formwork, is prepared for the filling of a liquid concrete material. Usually, the closing formwork also includes several formwork panels, which must be tightly connected to one another before the wall element is produced. To connect several formwork panels, formwork locks are attached, which connect adjacent formwork panels with one another. This attachment of Formwork locks are made from the scaffolding section of the closing formwork. On the scaffolding section, workers can reach the entire rear of the formwork panels. Furthermore, when preparing the formwork, anchors are attached between the formwork panels of the main formwork and the closing formwork, which ensure the static stability of the formwork while the concrete material is being poured in. In this case, several anchors must be arranged at different positions between the setting formwork and the closing formwork. This attachment or introduction of the anchor is also done by people who are on the scaffolding section. The scaffolding section is thus used for various tasks and work when preparing the formwork.

In a fifth method step E), liquid material, preferably a concrete material, is poured into the formwork. This filling of the material can also be done from the framework section. The scaffolding section offers a safe standing area from which feed elements for the concrete material, such as hoses, can be positioned according to the spatial area enclosed by the formwork. Alternatively, the scaffolding section can also be used only for observing and evaluating the filling of the formwork.

In a sixth method step F), the filled material is given time to harden and form a load-bearing wall element. In this method step, the framework section can be used to observe the curing process and, under certain circumstances, to influence it, for example by supplying water.

In a seventh method step G), the formwork panel is separated from the scaffolding section in the dismantled state in the case of the closing formwork, which is formed by the system. To do this, either the scaffolding interface of the connecting component can be separated from the scaffolding section, with the connecting component remaining on the formwork panel, or alternatively the formwork interface of the connecting component can be detached from the formwork panel, with the connecting component remaining on the formwork panel. Due to the corresponding design of the connection component, this connection can be released quickly and easily from the scaffolding section. In particular, no special tool is required for separating the formwork panel and scaffolding section and all or at least most of the steps required for this can be carried out by hand. The advantage of the method is that the scaffolding section can also be carried alone and stably during and after separation from the formwork panel and can be continuously entered and used by working people for work.

In an eighth method step H), the formwork panel of the closing formwork is removed, with the scaffolding section remaining in an unchanged position. The formwork panel of the closing formwork is preferably removed by a crane in a vertical upward direction. It is possible that before the formwork panel can be removed, it has to be separated from the created and hardened wall element by further work steps. After the formwork panel has been removed, the scaffolding section is at odds with the freshly created wall element. The distance between the scaffolding section and the wall element is approximately as large as the thickness of the previously removed formwork panel. Because of this small distance it is now possible to reach the wall element from the scaffold section. In addition, the formwork can also be removed in this process step, since the wall element has hardened and is self-supporting.

In a final, ninth method step I), the cast wall element is now processed further from the frame section that has remained in its position. During this further processing, for example, holes in the wall element caused by the previously attached anchors can be filled. In addition, unevenness on the wall element can be removed. Finally, it is also possible to carry out plastering or painting work on the wall element from the scaffolding section. The work can be carried out very efficiently, since the next work steps can be carried out from one and the same scaffolding section that has already been erected directly after the formwork has been stripped and the formlining has been removed.

The method according to the invention has the advantage that the scaffolding section, which is part of the closing shuttering, is used several times during the production of the wall element. First, the scaffolding section is erected in method step C) together with the formwork panel, which forms the closing formwork. The scaffolding section can be erected or placed very quickly, particularly if the system is erected or assembled before the closing formwork is erected. The assembled system is preferably simply placed using a crane. In this way, the closing formwork with the scaffolding section already arranged on it is erected and brought into position within a very short time. The formwork can then be prepared from the scaffold section. The concrete material can then be cast from the scaffold section into the formwork without further changes to the scaffold section and the formwork. Finally, after stripping, the formwork panel of the system can be removed, with one and the same scaffolding section remaining in the same position and being used for post-processing of the wall element produced. Compared to the conventional procedure, only a single scaffold section is required for activities that would otherwise require at least two different scaffold sections. This saves time and effort when creating the wall element. In addition, the logistics on the construction site are simplified, since only a single scaffolding section has to be brought in, assembled, dismantled and transported away again where otherwise at least two different scaffolding sections have to be kept ready and processed. The method according to the invention thus allows the efficiency on the construction site to be significantly increased and the production of a wall element is significantly simplified. In the method according to the invention, at least one system according to one of the previously described embodiments is used to produce a wall element. The use of an embodiment of a system for the production of a wall element brings about the same advantages as described above for the method.

In one embodiment of the method, it is provided that the formwork panel, the scaffolding section and the at least one connection component of the system are assembled before carrying out method step C). In this embodiment, the complete system or at least a part of the system is assembled as a closure formwork before the system is erected. This assembly can be made lying on the ground or underground, for example. This has the advantage that there are no risks during assembly due to the risk of falling that would otherwise exist when erecting a scaffolding section. Setting up the system on the ground thus significantly improves the occupational safety of the people working. In addition, the system can be set up in advance in this way away from the location where the wall element is to be built. The fully assembled system can then be transported very quickly to where the wall element is to be manufactured, for example using a crane. This procedure also improves the logistics at the site where the wall element is erected and there are fewer people in the danger zone near where the wall element is erected.

In a further embodiment it is provided that the connecting component is connected to the side of the formwork panel facing away from the formlining and thus the framework section on the side of the formwork panel facing away from the formlining is connected to the frame by the connecting component. In this embodiment, the connecting component is connected to the formwork panel, in particular to its frame, on the side facing away from the formwork skin. A plurality of connecting components are preferably arranged between a formwork panel and a scaffolding section. This means that the frame of the formwork panel can be used to connect one or more connecting components. The frame has a multiplicity of transverse struts and longitudinal struts, so that one or more connecting components can be fastened at various points on the formwork panel. This also makes it possible to establish a stable and load-bearing connection between the formwork panel and the scaffolding section using connecting components at a number of points.

The object of the invention is further achieved by an alternative method for producing a wall element comprising the steps

I) Structure of a system according to one of the previously described embodiments, wherein the at least one connecting component is connected to the scaffolding section with its scaffolding interface and to the formwork panel with its formwork interface, and wherein the system forms a setting formwork,

II) Attachment of reinforcement to the shell of the formwork panel of the system, the reinforcement being attached from the scaffolding section,

III) Setting up a closing formwork, with the closing formwork being introduced between the formwork panel and the scaffolding section and with the closing formwork and the formwork skin of the formwork panel delimiting the spatial area in which the wall element is provided and with the reinforcement being arranged between the closing formwork and the formwork panel,

IV) Preparation of the formwork for the filling of a liquid material between the initial formwork and the closing formwork, with anchors being introduced in particular, which connect the initial formwork and the closing formwork to one another,

V) filling the formwork with a liquid material,

VI) hardening of the material, whereby it forms the wall element together with the reinforcement, VII) Separation of the formwork panel from the framework section, whereby the framework interface of the connecting component is detached from the framework section or the formwork interface of the connecting component is detached from the formwork panel, and removal of the formwork panel,

VIII) removing the closing formwork, leaving the scaffolding section in an unchanged position,

IX) Finishing of the cast wall element from the scaffolding section.

This second method according to the invention is connected via the common inventive concept of first connecting a scaffolding section to a formwork panel and subsequently separating these two components from one another again, with the scaffolding section being used several times. The two methods according to the invention represent alternative solutions for the same task and are complementary to one another.

The second method according to the invention also serves to produce a wall element using a system according to one of the previously described embodiments. The second method is preferably also carried out in the specified order of the method steps. However, if necessary, the process steps can also be partially interchanged.

In a first method step I), such a system is set up, with the connecting component being arranged between a formwork panel, which serves as the setting formwork, and a scaffolding section which is at a distance from the formwork panel. In contrast to the method according to the invention described above, the distance between the formwork panel and the framework section of the system is significantly greater in the second method. The distance between the formwork panel, which here forms a setting formwork, and the scaffolding section is selected in such a way that the wall element and a closing formwork that is still to be installed fit into this distance. After the system has been set up, it is stable and stable on the ground, with the scaffolding section holding the formwork panel in position via the connection to the connecting component, so that no further support mechanisms are required for the setting formwork. In this way, such additional support mechanisms are saved, which reduces the effort.

In a second method step II), reinforcement is attached to the formwork skin or formwork panel of the system, which serves as the formwork. The reinforcement is attached to the formwork panel by workers who are located on the scaffolding section of the system and from there can easily reach the formwork panel in its entire height. In this way, an additional framework or additional work platforms are saved, which are required according to the prior art for attaching the reinforcement to the formwork panel.

In a third method step III), a closing formwork is erected, the closing formwork being formed in particular by a further formwork panel which is introduced into the already constructed system between the formwork panel, which serves as the setting formwork, and the scaffolding section. After setting up the closing formwork, the setting formwork and the closing formwork delimit the spatial area in which the wall element is to be created and in which the reinforcement was already created in the previous step was attached. The formwork panel, which forms the closing formwork, is preferably introduced vertically from top to bottom between the scaffolding section and the setting formwork. A crane can be used for this purpose, for example, which lowers the closing formwork at this point.

In a fourth process step IV), the formwork is prepared for the filling of a liquid concrete material between the initial formwork and the closing formwork. During this preparation, in particular, locks are arranged between formwork panels arranged next to one another and anchors are introduced, which hold the initial formwork and the closing formwork together and absorb forces which are exerted on the formwork by the concrete material subsequently introduced. This preparation of the formwork can be carried out from the scaffolding section, which is now on the side of the closing formwork facing away from the setting formwork. The closing formwork can thus be reached very easily from the scaffolding section. The advantage here is that the scaffolding section is already positioned and the formwork can be prepared from there immediately after the closing formwork has been erected.

In a fifth method step V), the formwork is filled with a liquid concrete material, which encloses the reinforcement arranged therein. The wall element is formed in the process. The liquid material can be poured into the formwork from the scaffolding section, which remains in the same position as before.

In a sixth method step VI), the concrete material is hardened, resulting in a load-bearing wall element. Cure testing can be performed from the scaffold section.

In a seventh method step VII), the system consisting of the formwork panel, which forms the setting formwork, scaffolding section and connecting component, is dismantled. For this purpose, the connection component is separated at least from the formwork panel or from the scaffolding section. Alternatively, the connection component can also be separated from both the formwork panel and the scaffolding section. In the dismantled state, the formwork panel, which forms the setting formwork, is then removed. This removal can be done, for example, by a crane. The connection component can also be separated from the formwork panel or from the scaffolding section from the scaffolding section.

In an eighth method step VIII), the formwork panel, which is located between the manufactured wall element and the scaffolding section and has formed the closing formwork there, is then removed. This removal is again preferably done in the vertical direction, for example by a crane. During and after removal of the closure formwork, the scaffolding section remains in its original position.

In a ninth method step IX), the wall element produced is post-processed. During this post-processing, for example, the anchor holes in the wall element can be filled and smoothed. Furthermore, other finishing work can be carried out, for example plastering or painting of the wall element. This reworking is in turn performed by the gantry section, which remains in its same position throughout the process. As a result, after the formwork has been removed, reworking can begin immediately and there is no need for time-consuming erection of a working scaffold after the wall element has been manufactured. Furthermore, it is possible to attach further formwork from the scaffolding section, for example to produce a ceiling section, which is to be arranged adjacent to the wall element created.

The second method according to the invention also has the advantage that a scaffolding section, which is already set up here in the first method step I), is used several times and for different tasks during the production of the wall element. This saves time and effort in erecting and dismantling different scaffolding systems for different tasks. In addition, the scaffolding section is advantageously used in connection with the connecting component as a support for the formwork to prevent it from falling over. This saves on other supporting mechanisms, for example pivotable supports, which are arranged on the setting formwork. As a result, the method for producing the wall element is further simplified and accelerated compared to the prior art.

In one embodiment of the second method, it is provided that in method step I) the formwork panel and the scaffolding section are set up at a distance from one another and the length of the at least one connecting component is equal to or greater than the thickness of the wall element to be produced. In this embodiment, the length of the connecting component determines the distance between the formwork panel, which serves as the setting formwork, and the scaffolding section. The length of the connecting component between its formwork interface and scaffolding interface is equal to or greater than the thickness of the wall element to be produced. The length of the connecting component is preferably greater than the total thickness of the wall element and the thickness of the closing formwork to be used in this way.

Furthermore, it is provided that in method step I) the at least one connecting component is fastened to the upward-facing edge of the formwork panel through the formwork interface. In this embodiment, the connection component is attached to the formwork panel by attaching the formwork interface to the edge of the formwork panel that faces upwards in the vertical direction. The connection component is thus arranged outside the area in which the reinforcement is attached and later the wall element is created. This arrangement means that there is no risk of collision between the connecting component and the wall element to be produced. The arrangement of the connecting component at the upper edge of the formwork panel is also particularly effective in order to secure the formwork panel, which forms the setting formwork here, against falling over. The connecting component is preferably connected to the frame section in an upper area via the frame interface. This arrangement also makes it possible to insert the formwork panel, which forms the closing formwork, after the reinforcement has been attached between the scaffolding section and the reinforcement, without causing a collision with the connecting component. Alternatively, it is also possible to connect the connection component or one or more other connection components to one or more lateral edges via the formwork interface with the to connect switchboard. For this purpose, the formwork interface can, for example, be designed in such a way that it encloses the edge area of the formwork panel and clamps it in the closed state.

It is also possible for process steps VII) and VIII) to be carried out in reverse order. In this embodiment of the second method, after the wall element has been produced, the closing formwork, which is arranged between the scaffolding section and the wall element, is first removed. During this removal of the closing formwork, the connecting component can still remain in the assembled position and connect the scaffolding section to the formwork panel, which forms the setting formwork. Only after the closing formwork has been removed is the connecting component dismantled and the formwork panel, which forms the setting formwork, removed. Even with this alternative order of the method steps, the scaffolding section always remains in its original position in order to subsequently enable post-processing of the wall element.

It is cleverly provided that when carrying out method step I), the scaffolding section is anchored in the ground. Such an anchoring further improves the stability of the system during and after the production of the wall element. The scaffolding section, which at the same time serves as a support for the formwork, can thus derive forces into the subsoil or ground via the anchoring. Additionally or alternatively, the formwork panel, which forms the formwork and is part of the system, can also be anchored in the ground.

Cleverly, it is provided that method step I) the scaffolding section is built up on the ground, as in the application, or the scaffolding section is placed on the ground for assembly. There are several possibilities for constructing the system and process step I). First, the system can be erected from the bottom up, starting from the ground or subsoil, which corresponds to the order of erection that is commonly used for a scaffolding section. Alternatively, the scaffolding section can also be erected lying on the ground at a different location, away from the position where the wall element is to be built. This has the advantage that there is no risk of people falling during the erection of the scaffolding section and therefore fewer safety precautions have to be taken. In addition, the scaffolding can be erected at a location on the construction site that is less frequented than the place where the structure is being built. This straightens out the logistics and makes work on the construction site easier. The scaffolding section assembled lying down can then be positioned, for example by a crane, at the point where the wall element is to be created. The connection of the formwork panel, which forms the formwork, to the scaffolding section by means of the connecting component is preferably carried out at the location where the wall element is to be created. Alternatively, it is also possible to assemble the system consisting of formwork panel, connecting component and scaffolding section at a different location and to position it completely in the assembled state where the wall element is to be created.

Features, effects and advantages that are disclosed in connection with the system are also deemed to be disclosed in connection with the methods. The same applies in reverse, characteristics Effects and advantages that are disclosed in connection with the methods are also deemed to be disclosed in connection with the system.

The same elements are provided with the same reference symbols in the figures. In general, the properties of an element that are described for one figure also apply to the other figures. Directional information such as above or below relates to the figure described and is to be transferred to other figures accordingly.

1 shows a perspective view of a first embodiment of a system 100 according to the invention. In this embodiment, the system 100 according to the invention shown comprises two formwork panels 2 which are oriented to the rear left. The two formwork panels 2 are arranged vertically one above the other and firmly connected to one another. In the illustrated embodiment, two identical formwork panels 2 are connected to each other in order to increase the formwork in its vertical extent. A system according to the invention comprises at least one formwork panel 2. The system 100 further comprises a scaffolding section 3 which is oriented to the front right, the formwork panel 2 and the scaffolding section 3 being connected to one another by four connecting components 1. This connection between formwork panel 2 and scaffolding section 3 is designed to be detachable. It is possible to extend the system 100 by providing a plurality of formwork panels 2 arranged parallel or aligned with one another and/or a plurality of scaffolding sections 3 or by providing a longer or higher scaffolding section 3 .

Each formwork panel 2 comprises a frame 21 on which a formwork skin 22 is arranged on the side pointing to the rear left in the illustration. The frame 21 is constructed here from steel tubes with a rectangular cross section. The frame is surrounded by a rectangular border which runs around frame 21 . Within this rectangular rim are a plurality of cross braces 212, which are shown oriented horizontally. A total of two vertically oriented longitudinal struts 211 are arranged perpendicularly thereto in the illustrated embodiment in the frame 21 . The transverse struts 212 and the longitudinal struts 211 cross and are connected to each other at each crossing point. This creates a stable, latticed frame 21 on which the formwork skin 22 rests at least in certain areas. Preferably, the connection between the formwork skin 22 and the frame 21 is designed so that it can be easily separated, allowing the formwork skin 22 to be easily replaced. The transverse struts 212 and the longitudinal struts 211 are oriented essentially perpendicularly to one another. Of course, different struts can also be arranged at a different angle to one another. In the embodiment shown, all cross braces 212 have at least one undercut 213 . In the illustrated embodiment, each crossbar 212 has two undercuts in 213 located on opposite sides of the crossbars 212, namely on the sides shown facing up and down. Details of a cross brace 212 and the undercuts 213 are shown in FIG. The undercuts 213 run in the respective longitudinal direction along the cross braces 212. In the illustrated embodiment, the undercuts 213 extend along the entire length of the cross braces 212. It is also possible along the Longitudinal struts 211 to arrange at least one undercut 213 of the same or similar design, at least in some areas.

The scaffolding section 3 extends in three spatial directions, has a three-dimensional structure and, in the embodiment shown, has three stepping levels which are arranged parallel and one above the other. The entire back of the formwork panel 2 can be easily reached by people who are on the scaffolding section 3 through these three stepping levels. The scaffolding section 3 comprises a plurality of vertical standards 51 oriented vertically in the representation and a plurality of horizontal bars 52 oriented horizontally in the representation. The vertical standards 51 and the horizontal bars 52 are connected to one another via interfaces. These interfaces are designed here as connecting disks or rosettes, which are fixedly arranged on the vertical posts 51 . The horizontal bars 52 have connecting areas which can be introduced into the connecting disks or rosettes in a form-fitting manner. In this way, the scaffolding section 3 has a modular structure and can therefore have different shapes and sizes, these different shapes and sizes being able to be formed by standardized vertical posts 51 and horizontal bars 52 . In addition, the scaffold section 3 shown has tread coverings in each of the three tread levels, which are each connected to a plurality of horizontal bars 52 here. The scaffolding section 3 can also include other scaffolding elements, such as railings or ladders.

In the system 100 shown, the formwork panel 2 and the scaffolding section 3 are connected to one another via a total of four connecting components 1 . Each of these connecting components 1 includes a support element 13, which is rod-shaped here. The support member 13 has a longitudinal axis extending in a direction in which the support member 13 has its longest dimension. In the illustrated embodiment, the longitudinal axis of the support elements 13 is oriented vertically and runs parallel to the vertical posts 51 of the frame section 3. In the illustrated embodiment, the support element 13 is formed by a metal tube with a square cross section. Of course, it is also possible to design the support element 13 differently, for example as a tube with a round cross section or as an aluminum profile or plastic profile. In the illustrated embodiment, each connecting component

I two formwork interfaces 12 and two framework interfaces 11. Each formwork interface 12 is provided for connecting the connecting component 1 to the formwork panel 2 and each framework interface 11 is provided for connecting the connecting component 1 to the framework section 3 and is connected to these components in the illustrated state. Details of the formwork interface 12 and scaffolding interface

II are shown enlarged in FIG. In the embodiment shown in FIG. 1 , the longitudinal axis of the support element 13 of the connecting component 1 is oriented essentially parallel to the surface of the formwork skin 22 and also essentially parallel to the frame 21 of the formwork panel 2 . Two formwork interfaces 12 are arranged on the support element 13 pointing in a direction towards the formwork panel 2 . Two scaffolding interfaces 11 are arranged on the supporting element on the opposite side of the formwork interface in FIG. Both the formwork interfaces 11 and the framework interfaces 12 are arranged at a distance from one another in a direction parallel to the longitudinal axis of the support element 13 . In the embodiment shown, there are therefore two of each other for each connecting component 1 spaced connection points of the connection component 1 with the formwork panel 2 and two spaced connection points of the connection component 1 with the scaffolding section 3. In addition, the four connection components 1 are arranged at a distance from one another. In each case two connecting components 1 are positioned vertically one above the other with their longitudinal axes aligned with one another. In the horizontal direction in the illustration, two connecting components 1 are oriented parallel to one another with the longitudinal axes of their support elements 13 . As a result of this arrangement, there are a total of eight connection points each between the formwork panel 2 and the connecting components 1 and between the framework section 3 and the connecting components 1 . In this way, the formwork panel 2 and the scaffolding section 3 are connected to one another in a stable and load-bearing manner. This stable connection makes it possible, for example, to transport the system 100 together while hanging on a crane. The connection is so stable that it is sufficient to attach a crane hook either to formwork panel 2 or to scaffolding section 3, with the connection points between scaffolding section 3 and formwork panel 2 being sufficiently stable to carry the other component during lifting.

The cross braces 212 of the frame 21 are for the most part arranged at a constant distance from one another. The distance between two formwork interfaces 12 is significantly greater than the distance between two adjacent crossbars 212. The distance between the two formwork interfaces 12, which are arranged on a common support element 13, corresponds to an integer multiple of the distance between two adjacent crossbars 212 Grid of the frame 21 and the connecting component 1 compatible with each other. This means that the positions of two transverse struts 212 and the two formwork interfaces 12 match one another, as a result of which a positive connection with one another becomes possible. In this case, it is possible for the connection component 1 to be attached at different positions relative to the frame 21 . The connection component 1 can thus be offset relative to the formwork panel 2 in the grid of the distances between the cross braces 212 . As a result, it is always possible to connect a connecting component 1 to one or more formwork panels 2 . In the illustrated embodiment, two formwork panels 2 are arranged vertically one above the other and connected to one another. It is often not possible to attach a formwork interface 12 at this connection point, which in the illustration is located approximately in the middle of the system 100 in the vertical direction. Due to the fact that the distance between two formwork interfaces 12 on a connecting element 1 is an integer multiple of the distance between two cross braces 212, the connecting component 1 can also be arranged in such a way that one of the two formwork interfaces 12 is on a formwork panel 2 and the second of the two Formwork interface in 12 are attached to an adjacent formwork panel 2, wherein the connecting component 1 simply overlaps the border area between the two formwork panels 2. As a result, the system 100 can be flexibly mounted in different positions of the components relative to one another and can therefore always be adapted to individual applications. In the embodiment shown, each connecting component 1 is only connected to one formwork panel 2 . However, it would also be possible, for example, to arrange a further, fifth connection component 1 in such a way that it is connected between the already positioned connection components 1 with a first formwork interface 12 with the upper formwork panel 2 and with its second formwork interface 12 with the lower formwork panel 2 connected is. The position of the connecting component 1 relative to the formwork panel 2 can also be flexibly selected in a direction parallel to the cross braces 212 . Details are shown in Fig. 2 and described.

FIG. 2 shows a perspective detailed view of a first embodiment of a system 100 according to the invention. FIG. 2 shows a detailed view of the system 100 from FIG. 1, which shows area II from FIG. The connecting component 1 includes the support element 13, which is oriented vertically here. A formwork interface 12 can be seen in FIG. 2, which is positively and non-positively connected to a cross brace 212. The formwork interface 12 here comprises a clamping element 121 with two gripping arms 1211 . The upper one of the gripping arms 121 1 is firmly connected to the support element 13 . The lower gripping arms 121 1 are movable relative to the upper gripping arms 1211 and the distance between the two gripping arms 1211 is adjustable. The clamp member 121 further includes an unlocking mechanism 1220 which moves the lower gripper arm 1211 relative to the upper gripper arm 1211. The unlocking mechanism 1220 has here as an actuating element a lever pointing to the front left in the illustration. When this lever is actuated, the distance between the two gripping arms 1211 is changed. The lever is operable with a simple linear movement. The clamping element 121 is connected to a cross brace 212, the gripping arms 1211 engaging in an undercut 213 on the frame 21 in certain areas. In the illustrated embodiment, an undercut 213, which has a rectangular cross section, runs along each cross brace 212 on the side facing upwards. A sectional view through a cross brace 212 is shown in FIG. On the side of the cross braces 212 pointing downwards there is also an undercut 213 which is opposite the undercut 213 on the upper side. In the embodiment shown, both gripping arms 1211 grip in regions in one of these two undercuts 213 in each case. Since the undercuts 213 extend along the longitudinal axis of the cross struts 212 , the clamping element 121 can be positioned at any position along the longitudinal direction of the cross struts 212 and clamped to the cross struts 212 using the unlocking mechanism 1220 . Thus, the relative position of the connecting component 1 relative to the cross brace 212 is continuously adjustable. In this way it is ensured that a connection between the scaffolding section 3 and the formwork panel 2 by the connecting component 1 is always possible in a direction running horizontally in the illustration. Possible differences in the grid in the horizontal direction between formwork panel 1 and scaffold section 3 thus do not impede the connection of the two components. As can be seen clearly in FIG. 2, the clamping element can be displaced at least between two adjacent longitudinal struts 211 over the entire width of the transverse struts 212. The relative position between scaffold section 3 and formwork panel 2 can thus be individually adapted to the requirements of the construction site. In addition, the operation of the clamping element 121 by the unlocking mechanism 1220 is very simple and can be carried out with little expenditure of time.

A framework interface 11 can be seen in the detailed view in FIG. This scaffolding interface 11 is designed, at least in some areas, to be complementary in shape to an interface on the vertical post 51 of the scaffolding section 3 shown on the left. Shape complementary means here that a portion of the Framework interfaces 11 fits geometrically in a portion of an interface on the vertical post 51. In the embodiment shown, the scaffolding interface 11 is designed identically to an interface which is arranged on the adjacent horizontal bar 52 of the scaffolding section 3 . Because the interfaces are the same, the framework interface 51 of the connecting component 1 can be connected to the same interfaces on the vertical standard 51 as the horizontal bars 52. There are therefore many different connection positions at which the connecting component 1 and framework section 3 can be connected to one another. This in turn results in a very flexible connection between the formwork panel 2 and the scaffolding section 3 . In the embodiment shown, connecting discs or rosettes are arranged on the vertical post 51 as interfaces for connecting to other scaffolding elements. The vertical post 51 shown on the left clearly shows that the scaffold interface 11 is connected to such a connecting disk on the side pointing to the left. The same connecting disc is connected to a horizontal bar 52 opposite this connection. It is easy to see that, at least in some areas, the connection interface 11 and the interface with which the horizontal bar 52 is connected to the vertical post 51 are identical. In the embodiment shown, the connection component 1 comprises a compensating element 14 which is arranged between the support element 13 and the framework interface 11 . This compensating element 14 enables tolerance compensation or other position compensation in the vertical direction between the connecting component 1 and the scaffolding section 3. For this purpose, the compensating element 14 has a linear bearing, which here includes a round bolt running parallel to the longitudinal direction of the support element 13. A tubular element is placed over this round bolt with a loose fit, so that it can be moved relative to the round bolt in a direction that is vertical in the illustration. The scaffold interface pointing away from the compensating element 14 can thus be displaced in the vertical direction along the length of the round bolt. This displaceability can also be used to connect the framework interface 11 to an interface on the framework section 3 . Furthermore, this compensating element can compensate for height differences in the subsoil that may exist between the subsoil under the formwork panel 2 and the subsoil under the scaffold section 3 . Such a compensating element 14 does not necessarily have to be provided, but it is helpful in order to further improve the connectivity between the formwork panel 2 and the scaffolding section 3 .

Fig. 3 shows a sectional view through a cross brace 212 of a formwork panel 2, which belongs to an embodiment of the system according to the invention. The cross braces 212 can be seen in FIG. 3, which are connected to the formwork interface 12 of the connecting component 1 in FIG. The cross brace 212 is shown in section in a plane perpendicular to its longitudinal direction. In the illustration to the left of the cross brace 212 , the formwork skin 22 , which is connected to the frame 21 , can also be seen in section. The formwork skin 22 rests flat on the left-hand side of the cross braces 212 . A longitudinal strut 211 can be seen in some areas in the background, which is connected to the sectioned transverse strut 212 . The illustration also shows the two gripping arms 1211 of the clamping element 121, which are connected to the cross brace 212 in a non-positive and positive manner. The cross brace 212 is formed by a profile tube which has the shape of a bone. On the side of the cross brace 212 that points upwards in the illustration and on the side that points downwards in the illustration an undercut 213 can be seen in each case, which is designed here as a groove which extends in the longitudinal direction of the cross brace 212, ie in the representation into the plane of the drawing. The grooves that form the two undercuts 213 have an identical, rectangular cross section here. The two undercuts 213 are arranged symmetrically in the vertical direction and opposite one another on the cross brace 212 . The areas of the gripper arms 1211 shown in FIG. 3 are identical. Both gripping arms 1211 have a projection 1211a on their tip, which is pointing to the left in the illustration, which here forms an area which engages in one of the undercuts in 213 in each case. 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, as a result of which the distance between the two gripping arms 1211 is designed to be adjustable. To establish a connection between the formwork interface 12 and the formwork panel 2, the lower gripper arm is moved vertically downwards in the direction symbolized by an arrow in the illustration, so that the distance between the two projections 1211a is greater than the width of the Cross braces 212 is in the vertical direction. The two gripper arms 1211 are then partially pushed over the cross braces 212 until the projections 1211a are adjacent to the two undercuts 213. The lower gripping arm 121 1 is then moved towards the upper gripping arm 1211 and the distance between the two gripping arms 121 1 is reduced. The two projections 1211a each engage in an undercut 213, resulting in a form fit. 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 direction of the undercuts 213 along the cross struts 212 until the desired relative position between clamping element 121 cross strut 212 is reached . The lower gripping arm 1211 is then moved towards the upper gripping arm 121 1 until the two gripping arms 121 1 clamp the cross braces 212 . In this state, there is also a flow of force between the clamping element 121 and the cross braces 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 connecting component 1 and the formwork panel 2. Such a connection can also be made between a clamping element 121 and a longitudinal strut 211. Also arranged in the background on the longitudinal strut 211 shown is an undercut 213 which is aligned with the undercuts 213 of the transverse strut 212 .

FIG. 4 shows a perspective view of a second embodiment of a system 100 according to the invention. The distance between the formwork panel 2 and the scaffolding section 3 is significantly greater here than in the embodiment in Fig. 1. The embodiment shown in Fig. 4 is designed in such a way that a wall element to be produced between the formwork skin 22 facing the scaffolding section 3 and the Scaffold section 3 can be produced. Reinforcement B is shown between the formwork skin 22 and the scaffolding section 3 , which is already attached to the formwork panel 2 here. The reinforcement B is formed here by several iron mats. In the illustrated embodiment, the connecting component 1 comprises a support element 13, the length of which is adjustable. The support element 13 is telescopic, which means that a portion of the support element S13 can be inserted into and pulled out of another part of the support element of FIG. 13 in order to adjust the overall length. As a result, the support element 13 can be used to adapt the distance between the framework section 3 and the formwork panel 2 to the wall element to be produced. In the embodiment shown in FIG. 4, the longitudinal direction of the support element 13 runs essentially horizontally, whereas the longitudinal direction of the support element 13 in FIG. 1 runs essentially vertically. The formwork interface 12 of the connecting component 1 is connected here to the edge of the formwork panel 2 pointing upwards in the illustration. The formwork interface 12 surrounds this edge. In the illustrated embodiment, too, the formwork interface 12 includes a clamping element 121 with two gripping arms in 1211. Details of the clamping element 121 are not shown in FIG. 4 for the sake of clarity. At least one of the gripping arms 1211 is movable essentially perpendicularly to the surface of the formlining 22 in the illustrated embodiment. As a result, a positive and non-positive connection between the clamping element 121 and the formwork panel 2 can also be produced in the illustrated embodiment. The connecting component 1 also includes a scaffolding interface 11, which is connected here to a horizontal bar 52 of the scaffolding section of FIG. This connection can be made, for example, via a clip or clamp connection. The arrangement of the connecting component 1 in the second embodiment shown makes it possible to arrange a further formwork panel 2 between the scaffolding section 3 and the formwork panel 2 without this arrangement being impeded by the connecting component 1 .

Fig. 5 shows a perspective detailed view of an embodiment of a formwork interface 12 of a connecting component 1. The connecting component 1 in the embodiment shown in Fig. 5 does not include a support element 13 Pipe section is formed with a round cross section. The size and shape of the cross section of the tubular section of the intermediate post 122 corresponds to the shape and size of a vertical post 51 of the scaffolding 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 brace 212 of the formwork panel 2. A scaffolding interface 11 is arranged on the intermediate post 122 . The relative position of the framework interface 11 and the intermediate post 122 can be adjusted here, with at least three possible positions of the framework interface 11 being provided on the intermediate post 122 . These three positions can be adjusted by sliding the scaffold interface 11 on the intermediate post 122 along its longitudinal direction. In the embodiment shown, both the framework interfaces 11 and the intermediate post 122 have bores into which a plug-in element can be inserted to pin out the position of the components relative to one another. Thus, in the illustrated embodiment, the position of the framework interface 11 relative to the clamping element 121 is designed to be adjustable. As a result, the connection component 1 can be easily adapted to different applications. Here, the scaffolding interface 11 is identical in shape and size to an interface that is also used within the scaffolding section 3 , in particular on a vertical post 51 . Thus, elements of the scaffolding section 3, such as a horizontal bar 52 shown in FIG. Also in the one shown in FIG Embodiment includes the clamping element 121 an unlocking mechanism 1220, through which the connection between the gripper arms 1211 and the crossbar 212 can be easily and quickly made and released again.

FIG. 6 shows a perspective detailed view of a further embodiment of a formwork interface 12 of a connecting component 1. FIG. 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 brace 212 of the formwork panel 2 . This pin element 1212 is covered in FIG. 6 and is therefore not shown. A corresponding recess suitable for receiving the spigot member 1212 is shown on the right adjacent the clamp member. The recess forms an undercut 213 here. The second gripping arm 1211 is formed by a clamping element 1213 in the illustrated embodiment. This tensioning element 1213 partially encompasses the cross brace 212 and bears against it. The clamping element 121 also includes a clamping mechanism, which here contains a threaded spindle and a handwheel. By this tightening mechanism, the relative position between the pin member 1212 and the tightening member 1213 can be changed. When the clamping element 121 is attached to the cross brace 212, the pin element 1212 is introduced into the recess and the tensioning mechanism is then actuated. As a result, the pin element 1212 and the tensioning mechanism 1213 are moved towards one another and a positive and non-positive connection is created between the clamping element 121 and the cross brace 212. A support element 13 is arranged on the clamping element 121 and the scaffold interfaces 12. This support element 13 connects the formwork interface 12 to a scaffold interface 11 . The connecting clamp 1214 encompasses the vertical post 51 and is non-positively attached to it with the aid of a screw connection. The advantage of this embodiment is that the scaffolding interface 11 designed as a connecting clamp 1214 can be continuously displaced along the vertical post 51 and then positioned in a non-positive manner. As a result, the position of the connecting component 1 relative to the frame section 3 can be adjusted very flexibly. It is also possible, if required, to arrange several scaffold interfaces 11 on the support element 13 .

7 shows a perspective detailed view of a further embodiment of a formwork interface 12 of a connecting component 1. In this embodiment of a connecting component 1, the position of the formwork interface 12 relative to the framework interface 11 is adjustable. For this purpose, the formwork interface 12 is designed as a compensating rail 1215 . This compensating rail 1215 comprises a first partial area which forms a gripping arm 1211 which is introduced into the undercut 213 in the cross brace 212 . This first partial area is formed by two flat bars arranged at an angle to one another, which are connected by a bolt which is oriented vertically in the illustration. This bolt is introduced into a cylindrical recess in the cross brace 212 which forms an undercut 213 . The second gripping arm 121 1 cannot be seen in the illustration and is formed by a locking pin which is introduced into the vertically oriented bolt on the side which is located below the cross brace 212 in the illustration. The equalizing rail 1215 also includes a second portion, which faces forward and to the right in the illustration. This second Partial area is formed by a rail with a constant cross-section, which has a rectangular cross-section here. In this embodiment, the framework interface 11 is formed by a clamp 1216 which is adjustably connected to the compensation rail 1215 . For this purpose, the clamp 1216 has a connection area, which in some areas is designed to be complementary in shape to the rail with a constant cross section of the compensating rail 1215. The connection area encompasses the rail with a constant cross-section and is displaceable along the longitudinal axis of the rail with a constant cross-section. The clamp 1216 also includes a locking element, which can be introduced into the connection area and which, in the state shown, clamps the clamp 1216 on the rail with a constant cross-section. In this state, the locking element and the connection area completely enclose the rail with a constant cross-section. When connecting scaffolding interface 11 and formwork interface 12, the connection area is first shifted relative to compensating rail 1215 until the desired position of formwork interface 12 and scaffolding interface 11 is reached. The locking element is then introduced and this relative position is fixed. The clamp 1216 also includes a connection clamp 1214, which is firmly connected to the connection area. As in the embodiment shown in FIG. The illustrated embodiment of a connecting component 1 is particularly advantageous because, on the one hand, the relative position between formwork interface 12 and scaffolding interface 11 is adjustable and, on the other hand, the position of the connection clamp 1214 of the scaffolding interface 11 is continuously adjustable relative to a vertical post 51. This embodiment of a connecting component 1 thus enables the position between the formwork panel 2 and the scaffolding section 3 to be adjusted in two spatial directions oriented perpendicularly to one another.

The embodiments of a connection component 1 illustrated in FIGS. 5 to 7 can all be used in a system 100 . It is also possible to use several embodiments of a connecting component 1 with one another and in combination with one another in a system 100 . Furthermore, it is possible in a system 100 to use one or more connection components 1 according to the embodiments shown in FIGS. 1 and 2 as an alternative and/or in addition. The embodiments shown in Figs. 1, 2, 5, 6 and 7 can thus be used in any combination with one another in a system 100 according to the invention, which means that there is a great deal of flexibility with regard to the type and position of the connection between a formwork panel 2 and a scaffolding section 3 is made possible.

FIG. 8 shows a perspective representation of a first state when carrying out a method according to the invention. In FIGS. 8 to 10 different states are shown when carrying out a method according to the invention, which occur chronologically one after the other in the method. A state can be seen in FIG. 8 in which a setting formwork has already been set up according to method step A). This formwork is composed here of a total of twelve formwork panels 12, which are connected to one another. The formwork is held in its vertically aligned position by a support M. Another support M is arranged on the rear-facing side, but this is covered by the formwork panels 2 . The setting formwork forms one half or side of a formwork used for erection of a wall element is required. Starting from the state shown in FIG. 8, a reinforcement B will next be attached to the setting formwork, which will be fastened to the setting formwork. This attachment of the reinforcement can be carried out from a scaffolding section, not shown, or using one or more work platforms.

FIG. 9 shows a perspective representation of a second state when carrying out a method according to the invention. In the state shown, reinforcement B has already been attached to the formwork. Furthermore, according to method step C), a system 100 was set up as a closing formwork opposite the main formwork and for probation B. The formwork panel 2 of the system 100 points with its formwork skin 22 to the reinforcement B and to the setting formwork, the setting formwork and the closing formwork together delimiting the spatial area in which the wall element is to be produced. Scaffolding section 3 is located on the side of formwork panel 2 of system 100 facing away from the setting formwork. The system here includes several formwork panels 2, which are oriented parallel to one another and connected to one another. Starting from the state shown in FIG. 9, according to method step D), the formwork can now be prepared for pouring in a liquid concrete material. For this purpose, for example, anchors are introduced between the setting formwork and the closing formwork, which absorb compressive forces acting on the formwork during the casting of the wall element. People can easily attach these anchors from scaffolding section 3. In addition, it is possible to carry out further work to prepare the formwork for scaffolding section 3. After the formwork has been prepared, liquid material is then poured into the formwork in accordance with method step E). This filling can also be done from the frame section 3. After the material has hardened according to process step F), the formwork can then be prepared for stripping. This preparation can in turn be carried out from the framework section 3. During this preparation for stripping, for example, the previously installed anchors between the initial formwork and the final formwork are removed again.

10 shows a perspective representation of a third state when carrying out a method according to the invention. In the state shown in FIG. 10, the formwork panel 2 has already been separated from the framework section 3 of the system 100 according to method step G). Furthermore, the formwork panel 2 was separated from the now hardened and self-supporting wall element W. To separate the formwork panel 2 from the scaffolding section 3 , the scaffolding interfaces 11 of the connecting components 1 were detached from the scaffolding section 3 . It can be seen that the connection components 1 are still connected to the formwork panel 2 via the formwork interfaces 12 and are removed together with it. Alternatively, it is also possible to separate the connection between the formwork interfaces 12 under the formwork panel 2 , with the connecting components 1 then remaining connected to the scaffolding section 3 . Alternatively, the connections of the formwork interfaces 12 and the framework interfaces 11 can also be released and the connecting components 1 can be separated from both the framework section 3 and the formwork panel 2 . The formwork panel 2 of the system 100 is removed here in the vertical direction, parallel to the wall element W produced and to the scaffolding section 3. The formwork panel 2 can be removed, for example, using a crane be removed, which lifts the formwork panel 2 upwards. During and after removing the formwork panel according to method step H), the scaffolding section 3 remains in an unchanged position parallel to the wall element W produced. In the state shown, the formwork was separated from the wall element W with the folded-out support M and moved to the rear left. The formwork can also be removed from the wall element using a crane. After the removal of the initial formwork and the closing formwork, further work can be carried out on the wall element W produced from the scaffolding section 3 without having to carry out work to set up another scaffolding or another working platform beforehand. The scaffolding section 3 is already positioned in such a way that work, such as filling holes previously left by the anchors, can be carried out from the scaffolding section 3 . The post-processing or finishing of the wall element W produced can thus be started immediately after the removal of the formwork panel 2, as a result of which the method for producing the wall element is simplified compared to the prior art and can be carried out in less time.

11 shows a perspective representation of a first state when carrying out an alternative method according to the invention. FIGS. 11 to 13 show various states occurring one after the other in the implementation of an alternative method for the production of a wall element. The alternative method differs from the previously described method in that the distance between the formwork panel 2 and the scaffolding section 3 of the system 100 is greater and the wall element is produced between the formwork panel 2 of the system 100 and the scaffolding section 3 . A state can be seen in FIG. 11 in which the system 100 has already been set up according to method step I) and forms a setting formwork. A total of three connecting components 1 connect the formwork panel 2 to the framework section 3 . The formwork skin 22 faces the framework section 3 . The wall element is later to be produced in the space between the formwork panel 2, in particular the formwork skin 22, and the scaffolding section 3. In the state shown in FIG. 11, a reinforcement B has already been attached to the formwork panel 2 according to method step II). This fastening of the reinforcement B was carried out by people who were on scaffolding section 3. The advantage of this embodiment is that the framework section 3 supports and positions the formwork panel 2 of the setting formwork, so that no support M, as in FIGS. 8 to 10, is required. At the same time, the scaffold section 3 can already be used to attach the reinforcement B to the formwork.

FIG. 12 shows a perspective representation of a second state when carrying out an alternative method according to the invention. In the state shown in FIG. 12, a further formwork panel 2 was set up as closing formwork between the formwork panel 2 of the system 100 that had already been set up and the scaffolding section 3 . This further formwork panel 2 was pivoted here with the aid of a crane from above between the formwork panel 2 that had already been erected and the scaffolding section 3 and was connected to the scaffolding section 3 . The setting formwork and the closing formwork together delimit the spatial area in which the wall element is to be produced and in which the reinforcement B has already been introduced. In the state shown in FIG. 12, people who are on the scaffold section 3 can now prepare the formwork for filling in a liquid concrete material according to process step IV). This preparation can include, for example, inserting anchors between the initial formwork and the final formwork. After the formwork has been prepared, liquid material is then poured into the formwork according to method step V) and the filled material is cured according to method step VI) until the wall element W itself is load-bearing. The material can also be filled into the formwork and the hardening of the material can be monitored from scaffold section 3 .

FIG. 13 shows a perspective representation of a third state when carrying out an alternative method according to the invention. In FIG. 13 a state can be seen which occurs during the implementation of method step VII), in which the formwork panel 2 is separated from the scaffolding section 3 . For this purpose, the connecting components 1 have already been dismantled, with both the formwork interface 12 and the scaffolding interface 11 being separated from the formlining 2 and the scaffolding section 3 in each case. The formwork panel 2, which forms the closure formwork, is removed straight up vertically in the state shown in FIG. 13, for example by means of a crane. The formwork panel 2, which forms the formwork, is symbolically offset backwards from the wall element W away. The removal of the formwork can also be done vertically upwards using a crane. After the removal of the initial formwork and closing formwork, the scaffolding section 3 remains in an unchanged position parallel to the manufactured wall element W. Thus, according to method step IX), the manufactured wall element W can be reworked or finished from this scaffolding section 3 . In this alternative method, too, the framework section 3 is thus used for several different tasks in the production of the wall element W, which are carried out one after the other. As a result, the process for manufacturing the wall panel W is simplified and can be carried out in less time.
