- 2 -case, the selection of the material and/or the dimensioning of the hollow profile depend inter alia on the size of the frame formwork.
Thin-walled hollow profiles are regarded as advantageous for producing a frame formwork since these help to save material and costs. At the same time, the weight of the frame formwork reduces, so that this is easier to handle. However, the use of thin-walled hollow profiles is accompanied by the risk that, when used in the intended manner, the frame formwork does not withstand the high loading. For example, the risk of buckling under a load is greater in the case of a thin-walled hollow profile.
When a frame formwork is used as intended for producing a wall section in concrete construction, at least two frame formwork elements are usually set up parallel and at a predetermined distance from one another and/or are coupled to at least one adjacent frame formwork element by means of clamps. When fresh concrete is poured between two parallel frame formwork elements, it must be ensured that the concrete does not press them apart.
The frame formwork elements must therefore be fixed, especially in the area of their base point. In the case of two adjacent frame formwork elements, the coupling area in particular must withstand the pressure of the concrete.
Based on the aforementioned prior art, the object of the present invention is to increase the load-bearing capacity of a frame formwork, and namely both the load-bearing capacity of the individual frame formwork element and the load-bearing capacity of the connecting and/or coupling areas of the frame formwork element.
So as to achieve the object, the frame formwork element having the features of claim 1 and the frame formwork system having the features of claim 9 are proposed.
Advantageous developments of the invention can be found in the respective subordinate claims. The object is further achieved by the proposed use of a batten in a frame formwork system in accordance with the invention.
Disclosure of the invention The frame formwork element which is proposed for a frame formwork system for producing a wall section in concrete construction comprises a plurality of edge profiles which form a frame having a frame inner side and a frame outer side. At least one edge profile is a hollow profile and in the cross-section has a profile section on the frame inner side having a groove-forming fastening corrugation and a profile section on the frame outer side having a groove-Date Recue/Date Received 2023-03-02

Advantageous developments of the invention can be found in the respective subordinate claims. The object is further achieved by the proposed use of a batten in a frame formwork system in accordance with the invention.
Disclosure of the invention The frame formwork element which is proposed for a frame formwork system for producing a wall section in concrete construction comprises a plurality of edge profiles which form a frame having a frame inner side and a frame outer side. At least one edge profile is a hollow profile and in the cross-section has a profile section on the frame inner side having a groove-forming fastening corrugation and a profile section on the frame outer side having a groove-Date Recue/Date Received 2023-03-02
- 3 -forming reinforcing corrugation. In the cross-section of the edge profile, the fastening corrugation and the reinforcing corrugation lie opposite one another other and have the same shape.
The frame of the frame formwork element can in particular have four edge profiles, two vertical edge profiles, a lower edge profile and an upper edge profile, so that the frame forms a quadrilateral, in particular a rectangle. A plurality of frame formwork elements of the same type can thus be set up next to one another and coupled in a simple manner in order to enable the production of a wall section in a predetermined length.
In the hollow profile design, the at least one edge profile of the proposed frame formwork element already has a high degree of inherent rigidity.
To further increase the load-bearing capacity, in particular to minimize the risk of buckling, the at least one edge profile comprises a groove-forming reinforcing corrugation in addition to a groove-forming fastening corrugation. While the fastening corrugation is formed on the frame inner side, the reinforcing corrugation is located on the frame outer side, i.e. in a profile section which extends essentially perpendicular to the plane of the frame or perpendicular to the plane of the formwork skin. The reinforcing corrugation thus increases the load-bearing capacity of the edge profile in the main load direction of the frame formwork element. The same applies moreover for the fastening corrugation, so that it also contributes to the reinforcing of the edge profile.
The groove-forming reinforcing corrugation lies opposite the groove-forming fastening corrugation in the cross-section of the edge profile. This means that the reinforcing corrugation is arranged at the same "height" in the direction of the profile depth as the fastening corrugation. In this manner, the two corrugations form a kind of constriction of the profile cross-section in the cross-section of the edge profile. This has an advantageous effect on the load distribution and/or load transfer when the frame formwork element is loaded perpendicular to the frame plane or in the main load direction.
The groove-forming reinforcing corrugation also has the same shape in the cross-section of the edge profile as the groove-forming fastening corrugation. This measure also has an advantageous effect on the load distribution and/or load transfer when the frame formwork element is loaded perpendicular to the frame plane or in the main load direction. The reinforcing corrugation and the fastening corrugation can have, for example, a V, U or trapezoidal shape in the cross-section of the edge profile. Such shapes can be produced in a Date Recue/Date Received 2023-03-02

Such shapes can be produced in a Date Recue/Date Received 2023-03-02
- 4 -simple manner during the production of the edge profile, for example in a forming process.
Due to the increased load-bearing capacity or the minimized risk of buckling, the wall thickness of the edge profile can subsequently be reduced. This means that a particularly thin-walled hollow profile can be used as an edge profile. Alternatively or additionally, the profile depth of the edge profile can be reduced. The profile depth corresponds to the dimension of the edge profile perpendicular to the plane of the frame or the formwork skin.
Both measures - alone or in combination - help to reduce the weight of the frame formwork element and thus make it easier to handle. Moreover, material is saved in the production of the frame formwork element, so that the production costs are reduced.
The hollow profile is preferably produced from metal, in particular steel, since steel has a high strength, so that the robustness of the frame formwork element is further increased.
The provision of a groove-forming reinforcing corrugation on the frame outer side in the at least one edge profile of the frame formwork element in accordance with the invention also has further advantages.
For example, the groove-forming reinforcing corrugation - analogous to the tongue-and-groove principle - can be used as a connecting and/or coupling element. This is possible since the groove-forming reinforcing corrugation is provided on the frame outer side or in a profile section of the edge profile which forms the frame outer side. The use of the groove-forming reinforcing corrugation as a connecting and/or coupling element simplifies the fixing of the frame formwork element, for example in the area of the base point.
Furthermore, the lateral connection of the frame formwork element and/or the coupling of the frame formwork element to another frame formwork element can be simplified. At the same time, the load-bearing capacity of the frame formwork element increases in these connecting or coupling areas, since the tongue-and-groove principle enables a positive fit to be achieved which acts in the main load direction of the frame formwork element.
Preferably, the groove-forming fastening corrugation and the groove-forming reinforcing corrugation each extend in the longitudinal direction of the profile over the entire length of the edge profile. The reinforcing effect is thus achieved over the entire length of the edge profile.
In addition, the connecting or coupling possibilities described above are created over the entire length of the edge profile.
In development of the invention, it is proposed that in the profile section on the frame outer Date Recue/Date Received 2023-03-02

This means that a particularly thin-walled hollow profile can be used as an edge profile. Alternatively or additionally, the profile depth of the edge profile can be reduced. The profile depth corresponds to the dimension of the edge profile perpendicular to the plane of the frame or the formwork skin.
Both measures - alone or in combination - help to reduce the weight of the frame formwork element and thus make it easier to handle. Moreover, material is saved in the production of the frame formwork element, so that the production costs are reduced.
The hollow profile is preferably produced from metal, in particular steel, since steel has a high strength, so that the robustness of the frame formwork element is further increased.
The provision of a groove-forming reinforcing corrugation on the frame outer side in the at least one edge profile of the frame formwork element in accordance with the invention also has further advantages.
For example, the groove-forming reinforcing corrugation - analogous to the tongue-and-groove principle - can be used as a connecting and/or coupling element. This is possible since the groove-forming reinforcing corrugation is provided on the frame outer side or in a profile section of the edge profile which forms the frame outer side. The use of the groove-forming reinforcing corrugation as a connecting and/or coupling element simplifies the fixing of the frame formwork element, for example in the area of the base point.

At the same time, the load-bearing capacity of the frame formwork element increases in these connecting or coupling areas, since the tongue-and-groove principle enables a positive fit to be achieved which acts in the main load direction of the frame formwork element.
Preferably, the groove-forming fastening corrugation and the groove-forming reinforcing corrugation each extend in the longitudinal direction of the profile over the entire length of the edge profile. The reinforcing effect is thus achieved over the entire length of the edge profile.
In addition, the connecting or coupling possibilities described above are created over the entire length of the edge profile.
In development of the invention, it is proposed that in the profile section on the frame outer Date Recue/Date Received 2023-03-02
- 5 -side the at least one edge profile which comprises the groove-forming reinforcing corrugation comprises at least one further groove-forming reinforcing corrugation and said groove-forming reinforcing corrugation extends parallel to the first groove-forming reinforcing corrugation in the longitudinal direction of the profile. The further reinforcing corrugation not only contributes to further reinforcing the edge profile and thus to an increase in the load-bearing capacity of the frame or the frame formwork element, but at the same time increases the connecting or coupling possibilities of the frame formwork element.
Preferably, accordingly at least two edge profiles which are arranged at an angle to one another or lying opposite one another, preferably all edge profiles of the frame, have a second groove-forming reinforcing corrugation.
The two parallel groove-forming reinforcing corrugations can have the same shape or different shapes in the cross-section of the edge profile. In particular, the two groove-forming reinforcing corrugations can have a V, U and/or trapezoidal shape in the cross-section of the edge profile. For example, the first groove-forming reinforcing corrugation can have a trapezoidal shape in the cross-section of the edge profile, while the second groove-forming reinforcing corrugation has a V-shaped cross-section.
Advantageously, the shape of the two groove-forming reinforcing corrugations differs in the cross-section of the edge profile. Due to the different shape of the groove-forming reinforcing corrugations, defined connecting or coupling geometries can be created, which are characteristic for a system which comprises further system components in addition to the frame formwork element in accordance with the invention. The defined connecting or coupling geometries ensure the compatibility of the system components. A

Preferably, not only one edge profile of the frame formwork element comprises a groove-forming fastening corrugation and a groove-forming reinforcing corrugation, but at least two edge profiles. This can be two edge profiles which are arranged at an angle to one another, for example a vertical and a lower edge profile, or two edge profiles which lie opposite one another, for example two vertical edge profiles.
The groove-forming fastening corrugations of two opposite-lying edge profiles can be used, for example, to fasten struts or rungs, which are arranged in the plane of the frame, to the frame. Analogous to the tongue and groove principle, the struts or rungs can each have a geometry which engages in the fastening groove at the end, so that a positive fit with the frame is achieved.

Preferably, accordingly at least two edge profiles which are arranged at an angle to one another or lying opposite one another, preferably all edge profiles of the frame, have a second groove-forming reinforcing corrugation.
The two parallel groove-forming reinforcing corrugations can have the same shape or different shapes in the cross-section of the edge profile. In particular, the two groove-forming reinforcing corrugations can have a V, U and/or trapezoidal shape in the cross-section of the edge profile. For example, the first groove-forming reinforcing corrugation can have a trapezoidal shape in the cross-section of the edge profile, while the second groove-forming reinforcing corrugation has a V-shaped cross-section.
Advantageously, the shape of the two groove-forming reinforcing corrugations differs in the cross-section of the edge profile. Due to the different shape of the groove-forming reinforcing corrugations, defined connecting or coupling geometries can be created, which are characteristic for a system which comprises further system components in addition to the frame formwork element in accordance with the invention.

The circumferential fastening corrugation enables both horizontally and vertically extending struts or rungs to be fastened. The circumferential reinforcing corrugation increases the connecting or coupling possibilities. In addition, the entire frame is reinforced by means of the circumferential corrugation.
Furthermore, all frame-forming edge profiles of a frame formwork element are preferably produced from the same hollow profile. All edge profiles of a frame thus have the same profile cross-section.
In a preferred embodiment of the invention, the frame of the proposed frame formwork element comprises four edge profiles which have the same profile cross-section and are connected to one another in such a manner that the at least one reinforcing corrugation which is arranged on the frame outer side is formed circumferentially.

With the aid of a tie, two frame formwork elements which are arranged in parallel can be braced together in the surface so that the concrete which is filled between the two frame formwork elements does not press them apart. In this manner, the tie promotes a high degree of evenness of the wall section which is to be produced.

Preferably, the batten comprises two oppositely profiled side faces and two end faces which connect the side faces. The oppositely profiled side faces form the connecting faces. They determine the depth of the batten. This preferably corresponds to the profile depth of the frame-forming edge profiles of the frame formwork element, so that the batten can be arranged in such a manner that it is flush with the frame of the frame formwork element.

This means that in the cross-section of the batten, the two end faces can be of the same or different length. If the two end faces have the same length, the batten has a constant width when the at least one projecting geometry and the groove-forming reinforcing corrugation ¨ if provided - are disregarded. If the two end faces have different lengths or the batten has a varying width, the latter can be used to couple two frame formwork elements which are arranged at an angle with respect to one another. This means that they do not extend in alignment, but rather at an angle < 180 or at an angle > 1800. If a plurality of battens of varying widths are used for coupling two frame formwork elements, the formwork skin can achieve a curvature which consists of a plurality of bends in the plane.

If a plurality of battens are used to couple two frame formwork elements, they do not necessarily have to be of the same design. This means that a batten having a varying width can also be coupled to a batten which has a constant width. Moreover two battens can be coupled to one another, each of which has a constant width but whose widths differ from one another. By providing battens of different widths, they can be easily exchanged and/or combined with one another as desired. This results in a modular system, which increases the variability of the frame formwork system.
In particular, the battens of different widths can be used to compensate the length. The battens having different widths can therefore be referred to as "compensating battens". A

This means that the dimension which is previously defined as the width now corresponds to the height of the batten. When a frame formwork element is placed on the batten, the projecting geometry is brought into engagement with the at least one groove-forming reinforcing corrugation of the lower horizontally extending edge profile of the frame formwork element.
In this manner, the batten determines the position of the frame formwork element. The batten can therefore also be referred to as a "positioning batten".

In development of the proposed frame formwork system, this therefore comprises at least one batten for positioning a frame formwork element. In order to fix the batten on the base side, it can have at least one opening for receiving a fastening means, for example a screw or a bolt. In particular, the opening can be designed as an elongated hole to enable precise alignment of the batten. Preferably, the opening is arranged in a lowered area of a projecting geometry of the batten, so that the fastening means does not protrude beyond the projecting geometry. This is because in this case the fastening means could hinder the positive fit of the batten having the edge profile of the frame formwork element which is to be positioned.
The fact that the opening is arranged in a lowered area of a projecting geometry of the batten means that the original height of the batten is also retained as a load-bearing cross-section.
Furthermore, the proposed frame formwork system preferably comprises a tension strap which is or can be fastened to the batten with the aid of the fastening means and which can be fastened at the other end in the same manner to a further, parallel batten, so that a distance between the two battens can be predetermined by means of the tension strap. The distance between the two battens also defines a distance between the two frame formwork elements which are positioned with the aid of the two battens. The distance preferably corresponds to the thickness of the wall section which is to be produced.

Detailed description of the drawings Fig. 1A shows a preferred embodiment of a frame formwork element 100 which comprises a frame 102, which is formed from four edge profiles 101, and a web bracing of horizontally and vertically extending rungs 108. Each of the four edge profiles 101 is designed as a hollow profile. All edge profiles 101 also have the same cross-section. This is shown enlarged in Figs. 1B to 1D for the upper edge profile 101 (Fig. 1B), the two lateral edge profiles 101 (Fig. 1C) and the lower edge profile 101 (Fig. 1D). Accordingly, all four edge profiles 101 have an essentially rectangular cross-section with a kind of collar as edge protection 111 for a formwork skin 110 (analogous to Fig. 3C). Furthermore, each edge profile 101 comprises a first profile section having a groove-forming fastening corrugation 107 which extends in the longitudinal direction of the profile and a second profile section having two groove-forming reinforcing corrugations 105, 106 which also extend in the longitudinal direction of the profile. The first reinforcing corrugation 105 lies exactly opposite the fastening corrugation 107 and also has the same cross-sectional shape.
This is trapezoidal. The other reinforcing corrugation 106, on the other hand, has a V-shaped cross-section.
The edge profiles 101 of the frame 102 are arranged in such a manner that the profile sections having the one fastening corrugation 107 form a frame inner side 103 and the profile sections having the two reinforcing corrugations 105,106 form a frame outer side 104 of the frame 102. Since the edge profiles 101 are connected by means of a miter 112, a circumferential fastening corrugation 107 is formed on the frame inner side and two circumferential reinforcing corrugations 105, 106 are formed on the frame outer side.
The frame formwork element 100 shown in Fig. 1A can be combined with a batten 200 in a frame formwork system 300 (see Figs. 3A to 3C). A preferred embodiment of a batten 200 of different widths b1-b3 is shown in Figs. 2A to 2D.

They have two profiled side faces 205, 206 and two end faces 207, 208 which connect the side faces 205, 206. The cross-sectional shape of the battens 200 shown is thus essentially rectangular, if the profiling of the side faces 205, 206 is disregarded. It is noticeable that the profiling of the side face 206 corresponds to the profiling of the frame outer side 104 of the frame 102 of the Date Recue/Date Received 2023-03-02
Detailed description of the drawings Fig. 1A shows a preferred embodiment of a frame formwork element 100 which comprises a frame 102, which is formed from four edge profiles 101, and a web bracing of horizontally and vertically extending rungs 108. Each of the four edge profiles 101 is designed as a hollow profile. All edge profiles 101 also have the same cross-section. This is shown enlarged in Figs. 1B to 1D for the upper edge profile 101 (Fig. 1B), the two lateral edge profiles 101 (Fig. 1C) and the lower edge profile 101 (Fig. 1D). Accordingly, all four edge profiles 101 have an essentially rectangular cross-section with a kind of collar as edge protection 111 for a formwork skin 110 (analogous to Fig. 3C). Furthermore, each edge profile 101 comprises a first profile section having a groove-forming fastening corrugation 107 which extends in the longitudinal direction of the profile and a second profile section having two groove-forming reinforcing corrugations 105, 106 which also extend in the longitudinal direction of the profile. The first reinforcing corrugation 105 lies exactly opposite the fastening corrugation 107 and also has the same cross-sectional shape.
This is trapezoidal. The other reinforcing corrugation 106, on the other hand, has a V-shaped cross-section.
The edge profiles 101 of the frame 102 are arranged in such a manner that the profile sections having the one fastening corrugation 107 form a frame inner side 103 and the profile sections having the two reinforcing corrugations 105,106 form a frame outer side 104 of the frame 102. Since the edge profiles 101 are connected by means of a miter 112, a circumferential fastening corrugation 107 is formed on the frame inner side and two circumferential reinforcing corrugations 105, 106 are formed on the frame outer side.
The frame formwork element 100 shown in Fig. 1A can be combined with a batten 200 in a frame formwork system 300 (see Figs. 3A to 3C). A preferred embodiment of a batten 200 of different widths b1-b3 is shown in Figs. 2A to 2D. The battens 200 are also designed as hollow profiles, analogous to the previously described edge profiles 101. They have two profiled side faces 205, 206 and two end faces 207, 208 which connect the side faces 205, 206. The cross-sectional shape of the battens 200 shown is thus essentially rectangular, if the profiling of the side faces 205, 206 is disregarded. It is noticeable that the profiling of the side face 206 corresponds to the profiling of the frame outer side 104 of the frame 102 of the Date Recue/Date Received 2023-03-02
- 14 -previously described frame formwork element 100, and the profiling of the side face 205 is formed in exactly the opposite manner. This means that the battens 200 can be coupled to one another as well as to the frame 102 of the frame formwork element 100.
When two battens 200 are coupled, projecting geometries 201, 202 on the side face 205 engage in the groove-forming reinforcing corrugations 203, 204 of the coupled batten 200, so that a positive fit is achieved. Such a coupling of the three battens 200 shown can be seen in Fig.
2D. Similarly, each of the battens 200 shown can be coupled to the frame 102 of the frame formwork element 101 of Fig. 1A.
Figs. 3A to 3C show a first frame formwork system 300 in accordance with the invention, having two frame formwork elements 100 according to Fig. 1A and three battens according to Fig. 2D. The two frame formwork elements 100 are coupled to one another by means of the three battens 200 (see in particular Figs. 3B and 3C). In this manner, in addition to the coupling of the frame formwork elements 100, a length compensation can be achieved at the same time. While the left-hand batten 200 engages positively in the edge profile 101 of the left-hand frame formwork element 100, the right-hand batten 200 forms two cavities 209 together with the edge profile 101 of the right-hand frame formwork element 100 (see in particular Fig. 3C). Sealing elements (not shown) can be inserted into these cavities 209 so that no water can escape via the joint area. At the same time, a coupling can be achieved by means of the sealing elements, which counteracts a relative movement of the coupled elements.
As can be seen in particular in Fig. 3C, the frame formwork elements 100 each have a formwork skin 110 which rests on the respective frame 102 and is flush with the edge protection 111 of the edge profiles 101 of the frame 102.
Figs. 4A to 4D show further battens 200 for a frame formwork system 300 according to Fig.
3A. These differ from one another by different widths b1 to b4, wherein each batten 200 has a variable width over the entire depth f of the batten. In the case of the batten 200 shown in Fig. 4A, the width b1 increases over the depth f, so that it has a width b1+
at the other end (the projecting geometries 201, 202 and the groove-forming reinforcing corrugations 203, 204 are not taken into account when determining the width). The batten 200 of Fig. 4C is designed analogous to the batten 200 of Fig. 4A, but has a smaller overall width b3, which increases to the width b3+. The opposite is true for the batten 200 in Fig. 4B
and Fig. 4D.
Here the width b2 or b4 decreases to a width b2- or b4-. With the aid of the battens 200 shown, bucklings and/or curvatures can be created in the plane of the formwork skin 110, as shown as an example in Figs. 5A and 5B.

In this manner, in addition to the coupling of the frame formwork elements 100, a length compensation can be achieved at the same time.

Figs. 4A to 4D show further battens 200 for a frame formwork system 300 according to Fig.
3A. These differ from one another by different widths b1 to b4, wherein each batten 200 has a variable width over the entire depth f of the batten. In the case of the batten 200 shown in Fig. 4A, the width b1 increases over the depth f, so that it has a width b1+
at the other end (the projecting geometries 201, 202 and the groove-forming reinforcing corrugations 203, 204 are not taken into account when determining the width). The batten 200 of Fig. 4C is designed analogous to the batten 200 of Fig. 4A, but has a smaller overall width b3, which increases to the width b3+. The opposite is true for the batten 200 in Fig. 4B
and Fig. 4D.
Here the width b2 or b4 decreases to a width b2- or b4-. With the aid of the battens 200 shown, bucklings and/or curvatures can be created in the plane of the formwork skin 110, as shown as an example in Figs. 5A and 5B. The course of the wall section which is to be Date Recue/Date Received 2023-03-02
- 15 -produced can be influenced in this manner. In particular, a convex course (Fig. 5A) or a concave course (Fig. 5B) can be specified. Instead of the two battens 200 shown, only one or more than two battens 200 can be used. Furthermore, different battens 200 can be used.
Another preferred batten 200 for a frame formwork system 300 in accordance with the invention can be seen in Figs. 6A and 6B. The batten 200 is used for positioning a frame formwork element 100 and is arranged for this purpose under the frame formwork element 100 or on the respective substrate. Due to the changed position of the batten 200, the original width now corresponds to the height of the batten. The batten 200 is placed on the substrate with the projecting geometries 201, 202 pointing upwards and is fixed in the substrate with the aid of fastening means 211 in the form of screws (see Fig.
6C). For receiving the fastening means 211, the batten 200 comprises a lowered area 212 in the area of the projecting geometry 201 with an opening 210 in the form of an elongated hole (see in particular Fig. 6B). The lowered area 212 ensures that the fastening means 211 does not protrude beyond the projecting geometry 201 of the batten 200. Since this would impair the positive fit between the batten 200 and the frame formwork element 100.
As shown as an example in Fig. 7, two such battens 200 can be arranged in a mirrored arrangement, at a distance from one another on the substrate and fixed. The distance is determined by the thickness of the wall section which is to be produced. A
frame formwork element 100 can then be placed on each of the two battens 200 so that the projecting geometries 201, 202 of the battens 200 engage in the corresponding groove-forming reinforcing corrugations 105, 106 of the respective frame formwork element 100. In this manner, a positive fit is achieved between the battens 200 and the frame formwork elements 100, which prevents the concrete placed between the two frame formwork elements 100 from pressing them apart when concreting the wall section which is to be produced.
However, this presupposes that the battens 200 are not pressed apart either.
To counteract this, the two battens 200 can be connected by means of tension straps 213 -as shown as an example in Figs. 8A to 8D. The tension straps 213 each have an opening 215 in the form of an elongated hole at their two ends for receiving locking bolts 214 (see Fig. 8B), by means of which the tension straps 213 can be connected to the battens 200.
Instead of the locking bolt 214, the fastening means 211 in the form of a screw can also be used, with the aid of which the batten 200 can be anchored in the substrate at the same time.
A preferred locking bolt 214 is shown as an example in Fig. 9B. It comprises an elongated Date Recue/Date Received 2023-03-02
Another preferred batten 200 for a frame formwork system 300 in accordance with the invention can be seen in Figs. 6A and 6B. The batten 200 is used for positioning a frame formwork element 100 and is arranged for this purpose under the frame formwork element 100 or on the respective substrate. Due to the changed position of the batten 200, the original width now corresponds to the height of the batten. The batten 200 is placed on the substrate with the projecting geometries 201, 202 pointing upwards and is fixed in the substrate with the aid of fastening means 211 in the form of screws (see Fig.
6C). For receiving the fastening means 211, the batten 200 comprises a lowered area 212 in the area of the projecting geometry 201 with an opening 210 in the form of an elongated hole (see in particular Fig. 6B). The lowered area 212 ensures that the fastening means 211 does not protrude beyond the projecting geometry 201 of the batten 200. Since this would impair the positive fit between the batten 200 and the frame formwork element 100.
As shown as an example in Fig. 7, two such battens 200 can be arranged in a mirrored arrangement, at a distance from one another on the substrate and fixed. The distance is determined by the thickness of the wall section which is to be produced. A
frame formwork element 100 can then be placed on each of the two battens 200 so that the projecting geometries 201, 202 of the battens 200 engage in the corresponding groove-forming reinforcing corrugations 105, 106 of the respective frame formwork element 100. In this manner, a positive fit is achieved between the battens 200 and the frame formwork elements 100, which prevents the concrete placed between the two frame formwork elements 100 from pressing them apart when concreting the wall section which is to be produced.
However, this presupposes that the battens 200 are not pressed apart either.

The tension straps 213 each have an opening 215 in the form of an elongated hole at their two ends for receiving locking bolts 214 (see Fig. 8B), by means of which the tension straps 213 can be connected to the battens 200.
Instead of the locking bolt 214, the fastening means 211 in the form of a screw can also be used, with the aid of which the batten 200 can be anchored in the substrate at the same time.
A preferred locking bolt 214 is shown as an example in Fig. 9B. It comprises an elongated Date Recue/Date Received 2023-03-02
- 16 -head 216 which is aligned transversely to the longitudinal direction of the batten 200 when it is inserted into the opening 215 of the tie strap 213 and is then twisted so that it is aligned parallel to the longitudinal direction of the batten 200. The locking bolt 214 is inserted analogous to the fastening means 211 into an opening 210 of a lowered area 212 of the batten 200 (see Fig. 9A). This ensures that the locking bolt 214 does not also protrude beyond the projecting geometry 201 of the batten 200. Rotating the locking bolt 214 so that the elongated head 216 is aligned parallel to the longitudinal direction of the batten 200 further ensures that it remains completely behind the projecting geometry 201 (see Figs. 9C
to 9E). The positive fit between the batten 200 and the frame formwork element 100 is therefore not compromised.
Fig. 10 shows another frame formwork system 300 for producing a wall section in concrete construction. The frame formwork elements 100 are each positioned by means of battens 200 on the base side and held at a distance which corresponds to the thickness of the wall section which is to be produced. As previously described, the battens 200 are fixed to the substrate by means of fastening means 211 in the form of screws. The distance between the battens 200 is maintained by tension straps 213, each of which is connected to the battens 200 by means of locking bolts 214. Neither the fastening means 211 nor the locking bolts 214 project beyond the projecting geometries 201 of the battens 200, so that these engage positively in the corresponding groove-forming reinforcing corrugation 105 of the respective frame formwork element 100. The frame formwork elements 100 are thus positioned over the base-side battens 200 and held at a distance.
A plurality of tie holes 109 are provided in the vertical rungs 108 of the frames 102 of the frame formwork elements 100. These are also formed in the respective formwork skin 110.
Thus, anchor tie rods 302 can be inserted into the tie holes 109 and enable two opposing frame formwork elements 100 to be braced together (see as an example Fig. 12).
In addition to the battens 200 for positioning the frame formwork elements 100, the frame formwork system 300 shown in Fig. 10 also comprises battens 200 for coupling two adjacent frame formwork elements 100. In this case, the coupling is achieved with the aid of two coupled battens 200 of different widths.
Fig. 11 shows another framed formwork system 300, which largely corresponds to that of Fig. 10. Here, however, two framed formwork elements 100 are coupled by means of three coupled battens 200 of different widths.
