Definitions
- Frame formwork element and frame formwork system use of a batten in a frame formwork system
- the invention relates to a frame formwork element for a frame formwork system for producing a wall section in concrete construction.
- the invention relates to a frame formwork system with at least one frame formwork element according to the invention and at least one batten for producing a wall section in concrete construction.
- the invention relates to the use of a bar in a panel formwork system.
- Patent specification DE 39 11 301 C1 gives an example of a formwork element for concrete formwork, which comprises a frame formwork with a formwork skin and a facing formwork which is applied to the formwork skin of the frame formwork.
- the facing formwork forms a kind of second formwork skin.
- a facing formwork serving as a second formwork skin, as described in the patent specification DE 39 11 301 C1, can but does not necessarily have to be provided.
- the frame formwork described in DE 39 11 301 C1 has a peripheral frame for receiving the (first) formwork skin.
- the formwork skin is placed on the outside of the frame, so that the end faces of the formwork skin are encompassed by a peripheral edge of the frame.
- the peripheral edge preferably terminates flush with the surface of the formlining.
- Support struts can be arranged between the legs of the frame to support the formwork skin in its planar extent.
- To the Connection of the support struts to the frame can have a peripheral groove-forming fastening bead on the inside. The fastening groove can also serve to accommodate clamps for connecting two adjacent panel formwork elements.
- the formwork skin can be made of wood, plastic or a composite material which comprises at least one of these materials.
- Hollow profiles made of metal, in particular steel, are usually used to produce the frame.
- a light metal such as aluminum can also be used.
- the choice of material and/or the dimensioning of the hollow profiles depends, among other things, on the size of the panel formwork.
- Thin-walled hollow profiles are considered to be advantageous for the production of a frame formwork, since they help to save material and costs. At the same time, the weight of the panel formwork is reduced, making it easier to handle. However, the use of thin-walled hollow profiles is associated with the risk that the panel formwork will not withstand the high loads when used as intended. For example, the risk of buckling is greater in a thin-walled hollow profile under load.
- frame formwork When frame formwork is used as intended to produce a wall section in concrete construction, at least two frame formwork elements are generally set up parallel and at a specified distance from one another and/or coupled to at least one adjacent frame formwork element using clamps.
- the frame formwork elements When pouring fresh concrete between two panel formwork elements arranged in parallel, it must be ensured that the concrete does not push them apart.
- the frame formwork elements must therefore be fixed in particular in the area of their base. In the case of two adjacent panel formwork elements, the coupling area in particular must be able to withstand the pressure of the concrete.
- the object of the present invention is to increase the load capacity of a frame formwork, specifically both the load capacity of the individual frame formwork element and the load capacity of the connection and/or coupling areas of the frame formwork element.
- the frame formwork element proposed for a frame formwork system for producing a wall section in concrete construction has a plurality of edge profiles which form a frame with a frame inside and a frame outside.
- At least one edge profile is a hollow profile and has, in cross section, a profile section on the inside of the frame with a groove-forming fastening bead and a profile section on the outside of the frame with a groove-forming reinforcement bead.
- the fastening bead and the stiffening bead are located opposite one another in the cross section of the edge profile 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 square, 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 of a predetermined length.
- the at least one edge profile of the proposed frame formwork element already has a high degree of dimensional stability.
- the at least one edge profile has a groove-forming reinforcement bead in addition to a groove-forming fastening bead. While the fastening bead is formed on the inside of the frame, the stiffening bead is on the outside of the frame, that is to say in a profile section which runs essentially perpendicular to the plane of the frame or perpendicular to the plane of the formwork skin. The stiffening bead thus increases the load-bearing capacity of the edge profile in the main load direction of the panel formwork element. The same applies to the fastening bead, so that this also contributes to the reinforcement of the edge profile.
- the groove-forming stiffening bead lies opposite the groove-forming fastening bead in the cross-section of the edge profile. This means that the stiffening bead is arranged at the same "height" as the fastening bead in the direction of the profile depth. In this way, the two beads 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 panel formwork element is loaded perpendicularly to the frame plane or in the main loading direction.
- the groove-forming stiffening bead also has the same shape as the groove-forming fastening bead in the cross section of the edge profile. This measure also has an advantageous effect on the load distribution and/or load transfer when the frame formwork element is loaded perpendicularly to the plane of the frame or in the main loading direction.
- the stiffening bead and the fastening bead can have, for example, a V, U or trapezoidal shape in the cross section of the edge profile.
- Such forms can be produced in a simple manner when producing the edge profile, for example in a forming process.
- the wall thickness of the edge profile can be reduced as a result.
- a particularly thin-walled hollow profile can be used as an edge profile.
- 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 formlining.
- the hollow profile is preferably made of metal, in particular steel, since steel has high strength, so that the robustness of the frame formwork element is further increased.
- a stiffening bead forming a groove on the outside of the frame in the at least one edge profile of the frame formwork element also has further advantages.
- the groove-forming stiffening bead can be used as a connection and/or coupling element, analogous to the tongue and groove principle. This is possible because the groove-forming stiffening bead is provided on the outside of the frame or in a profile section of the edge profile that forms the outside of the frame.
- the use of the groove-forming stiffening bead as a connection and/or coupling element simplifies the fixing of the frame formwork element, for example in the area of the base.
- the lateral connection of the panel formwork element and/or the coupling of the panel formwork element to another panel formwork element can be simplified.
- the load-bearing capacity of the panel formwork element increases in these connection or coupling areas, since the tongue and groove principle can be used to achieve a form fit acting in the main load direction of the panel formwork element.
- the groove-forming fastening bead and the groove-forming stiffening bead each extend in the longitudinal direction of the profile over the entire length of the edge profile.
- the stiffening effect is thus achieved over the entire length of the edge profile.
- the connection or coupling options described above are created over the entire length of the edge profile.
- the at least one edge profile having the groove-forming reinforcement bead has at least one further groove-forming reinforcement bead in the profile section on the outside of the frame, which runs parallel to the first groove-forming reinforcement bead in the longitudinal direction of the profile.
- the further stiffening bead not only contributes to further stiffening of the edge profile and thus to an increase in the load-bearing capacity of the frame or frame formwork element, but at the same time expands the connection or coupling possibilities of the frame formwork element.
- at least two edge profiles arranged at an angle to one another or opposite one another, preferably all edge profiles of the frame preferably have a second, groove-forming reinforcement bead.
- the two parallel, groove-forming stiffening beads can have the same shape or different shapes in the cross section of the edge profile.
- the two groove-forming stiffening beads can have a V, U and/or trapezoidal shape in the cross section of the edge profile.
- the first groove-forming stiffening bead can have a trapezoidal shape in cross section of the edge profile, while the second groove-forming stiffening bead is V-shaped in cross section.
- the shape of the two groove-forming stiffening beads differs in the cross section of the edge profile. Due to the different shape of the groove-forming stiffening beads, defined connection or coupling geometries can be created that are characteristic of a system that includes other system components in addition to the frame formwork element according to the invention. The defined connection and coupling geometries ensure the compatibility of the system components. A corresponding panel formwork system is described in more detail below.
- an edge profile of the frame formwork element has a groove-forming fastening bead and a groove-forming stiffening bead, but at least two edge profiles.
- This can involve two edge profiles arranged at an angle to one another, for example a vertical and a lower edge profile, or two edge profiles lying opposite one another, for example two vertical edge profiles.
- Struts or rungs arranged in the plane of the frame can be fastened to the frame via the groove-forming fastening beads of two opposite edge profiles.
- the ends of the struts or rungs can each have a geometry that engages in the fastening groove, so that a form fit with the frame is achieved.
- the positive locking acts in the main load direction of the panel formwork element, so that the formlining lying against the struts or rungs is optimally supported.
- the groove-forming fastening beads can serve to accommodate clamps for connecting two adjacent panel formwork elements.
- the groove-forming stiffening beads of two edge profiles that are at an angle to one another or that lie opposite one another can be used in particular to form a lateral and/or lower connection of a panel formwork element and/or to couple two adjacent panel formwork elements.
- All frame-forming edge profiles of the frame formwork element preferably have a groove-forming fastening bead and a groove-forming stiffening bead, so that a circumferential fastening bead is formed on the inside of the frame and a circumferential stiffening bead is formed on the outside of the frame.
- the all-round fastening bead enables fastening of both horizontal and vertical struts or rungs.
- the all-round reinforcement bead expands the connecting and coupling options.
- a stiffening of the entire frame is achieved via the surrounding beads.
- all frame-forming edge profiles of a frame formwork element are preferably made from the same hollow profile. All edge profiles of a frame therefore have the same profile cross section.
- the frame of the proposed frame formwork element comprises four edge profiles with the same profile cross section, which are connected to one another in such a way that the at least one reinforcement bead arranged on the outside of the frame is formed circumferentially.
- the edge profiles can be connected to one another, for example via a miter.
- the proposed frame formwork element preferably also has: a formwork skin resting on the edge profiles and/or a plurality of rungs which are arranged in the plane of the frame and run perpendicular to one another and/or to the edge profiles and which are connected to the edge profiles.
- the formlining can be bordered on the face side by an edge of the frame.
- the edge protects the face of the formlining from damage.
- the edge of the frame preferably terminates flush with the formlining.
- the several rungs arranged in the frame level - if provided - support the formlining. In this way, comparatively large, in particular large-area, frame formwork elements can be manufactured.
- the rungs can also have one or more anchor holes for receiving anchors. With the help of an anchor, two panel formwork elements arranged in parallel can be clamped together across the surface so that the concrete poured between the two panel formwork elements does not push them apart. In this way, the anchor promotes a high degree of evenness in the wall section to be produced.
- the frame formwork system also proposed for the production of a wall section in concrete construction has at least one frame formwork element according to the invention and at least one strip for arrangement on the outside of the frame on an edge profile of the frame of the frame formwork element.
- the additionally provided bar expands the application possibilities of the panel formwork system.
- the bar enables length or height compensation.
- the strip can be used as a connection and/or coupling element.
- the bar of the proposed frame formwork system has at least one projecting geometry that can be brought into engagement with the at least one groove-forming stiffening bead of the edge profile of the frame formwork element. This means that the protruding geometry of the strip and the groove-forming stiffening bead of the edge profile interact according to the tongue and groove principle. A form fit is thus achieved between the strip and the frame formwork element, which increases the load-bearing capacity of the connection or coupling area in the main load direction.
- the strip can be arranged at any point on the outside of the frame. This means that the strip can be arranged laterally next to, below or above the frame of the frame formwork element and can be positively connected to it.
- a laterally arranged bar can be used in particular for coupling two adjacent panel formwork elements.
- a length compensation can be created with the help of this strip.
- radii can be displayed.
- the frame formwork element can be precisely positioned and aligned with the aid of a compensating strip arranged under a frame of a frame formwork element.
- the at least one bar can thus fulfill a large number of different tasks.
- the bar can be a connecting, coupling, compensating, positioning and/or buckling bar.
- the at least one projecting geometry of the strip preferably extends in the longitudinal direction of the strip. Furthermore, the protruding geometry preferably extends over the entire length of the strip. The positive fit with the corresponding edge profile of the frame formwork element is thus also achieved over the entire length of the strip, which further increases the load capacity of a connection or coupling area formed with the help of the strip.
- the at least one projecting geometry in the cross section of the strip has an outer contour which is adapted to an inner contour of the at least one groove-forming reinforcement bead of the edge profile.
- the cross-sectional shape of the protruding geometry of the strip is designed to be opposite to the cross-sectional shape of the groove-forming stiffening bead of the edge profile. In this way, a high degree of accuracy of fit is achieved in the area of the form fit. This in turn counteracts a relative movement of the strip with respect to the edge profile.
- the strip has at least one groove-forming reinforcement bead extending in the longitudinal direction of the strip on the side facing away from the projecting geometry for receiving a projecting geometry of a further strip and/or a sealing element.
- the strip thus has two connection sides, the first connection side having a protruding geometry and the second connection side having a groove-forming reinforcement bead.
- the protruding geometry and the groove-forming stiffening bead are preferably arranged opposite each other or at the same “height” in the cross section of the strip, so that the strip can be connected to a large number of similar strips by simply plugging them into one another. In this way, a form fit between the strips that is effective in the main direction of loading is achieved at the same time.
- two strips each with at least one groove-forming reinforcement bead, can be arranged and aligned with one another in such a way that the respective groove-forming reinforcement beads are opposite one another.
- a corresponding cavity can - alternatively or additionally - also be created between a strip and an edge profile of a frame formwork element, since this also has at least one groove-forming reinforcement bead on the outside of the frame.
- the bar is advantageously a hollow profile.
- the strip per se already has a high degree of dimensional stability.
- the dimensional stability is additionally increased by the at least one projecting geometry and--if provided--by the at least one groove-forming reinforcement bead extending in the longitudinal direction of the strip.
- the hollow profile is advantageously made of metal, in particular steel, since steel is particularly strong and therefore robust.
- the strip preferably has two side faces profiled in opposite ways and two end faces connecting the side faces.
- the oppositely profiled side surfaces form the connection surfaces.
- the two end faces of the bar define the width of the bar, with the width being able to vary. This means that in the cross section of the strip, the two end faces can be of the same length or of different lengths. With the same length of the two end faces, the strip has a constant width if the at least one projecting geometry and the groove-forming stiffening bead—if present—are disregarded.
- the strip can be used to couple two panel formwork elements that are arranged at an angle to one another. This means that they do not run in alignment but are arranged at an angle of ⁇ 180° or at an angle of >180°. If several battens with varying widths are used to couple two panel formwork elements, a curvature consisting of several kinks can be achieved in the plane of the formwork skin. Such a bar can therefore also be referred to as a "buckling bar".
- battens are used to couple two panel formwork elements, they do not necessarily have to be of the same design.
- a bar with a varying width can also be coupled with a bar with the same width.
- two bars can be coupled, each of which has a constant width, but whose widths differ from one another.
- strips in different widths they can be easily exchanged and/or combined with one another as desired.
- a kind of modular system is created that increases the variability of the panel formwork system. In particular, length compensation can be achieved with the help of the strips of different widths.
- the strips of different widths can therefore be referred to as "compensation strips”. Compensating strips and buckling strips can also be used in combination.
- the proposed frame formwork system therefore has a plurality of strips which can be brought into engagement with one another and with at least one edge profile of the frame of the frame formwork element and preferably differ from one another in terms of their widths.
- at least one bar has a varying width.
- the at least one strip of the proposed panel formwork system can also be used to position a panel formwork element.
- the strip is fixed on the existing subsurface or floor, so that the at least a protruding geometry points upwards. This means that the dimension previously defined as width now corresponds to the height of the bar.
- the projecting geometry is brought into engagement with the at least one groove-forming stiffening bead of the lower, horizontally running edge profile of the panel formwork element.
- the strip specifies the position of the panel formwork element.
- the bar can therefore also be referred to as a "positioning bar".
- the form fit achieved via the protruding geometry of the strip not only facilitates the positioning or alignment of the frame formwork element, but also leads to a fixation of the frame formwork element in the area of its base.
- this therefore has at least one bar for positioning a frame formwork element.
- it can have at least one opening for receiving a fastening means, for example a screw or a bolt.
- the opening can be designed in particular as an elongated hole in order to enable the strip to be precisely aligned.
- the opening is preferably arranged in a lowered area of a protruding geometry of the strip, so that the fastening means does not protrude beyond the protruding geometry. Because in this case the fastening means could impede the positive fit of the strip with the edge profile of the panel formwork element to be positioned. Due to the fact that the opening is arranged in a lowered area of a protruding geometry of the bar, the original height of the bar is also retained as a supporting cross-section.
- the proposed frame formwork system preferably has a tie rod that is or can be fastened to the strip with the aid of the fastening means, the other end of which can be fastened in the same way to another, parallel strip, so that the tie rod can be used to specify a distance between the two strips.
- the distance between the two strips also defines a distance between the two panel formwork elements, which are positioned using the two strips.
- the distance preferably corresponds to the thickness of the wall section to be produced.
- a bar with at least one projecting geometry in a frame formwork system in particular for positioning a frame formwork element and/or for coupling two frame formwork elements.
- the strip is arranged on the outside of the frame on an edge profile of the frame formwork element and the at least one projecting geometry is brought into engagement with a groove-forming stiffening bead of the edge profile.
- a connecting, coupling, compensating, positioning and/or buckling strip can be used.

- FIG. 1A shows a preferred embodiment of a frame formwork element 100, which comprises a frame 102 formed from four edge profiles 101 and an infill of horizontally and vertically running 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 (similar to FIG. 3C).
- each edge profile 101 has a first profile section with a groove-forming fastening bead 107 extending in the longitudinal direction of the profile and a second profile section with two stiffening beads 105, 106 also extending in the longitudinal direction of the profile and forming a groove.
- the first stiffening bead 105 is located exactly opposite the fastening bead 107 and also has the same cross-sectional shape. This is trapezoidal.
- the further stiffening bead 106 has a V-shaped cross section.
- the edge profiles 101 of the frame 102 are arranged in such a way that the profile sections with the one fastening bead 107 form a frame inside 103 and the profile sections with the two stiffening beads 105, 106 form a frame outside 104 of the frame 102. Since the edge profiles 101 are connected via a miter 112, a fastening bead 107 running around the inside of the frame and two reinforcing beads 105, 106 running around the outside of the frame are formed.
- the frame formwork element 100 shown in FIG. 1A can be combined with a strip 200 in a frame formwork system 300 (see FIGS. 3A to 3C). A preferred embodiment of a strip 200 in different widths b1-b3 is shown in FIGS. 2A to 2D.
- the strips 200 are also designed as hollow profiles, analogously to the edge profiles 101 described above. They have two profiled side faces 205, 206 and two end faces 207, 208 connecting the side faces 205, 206.
- the cross-sectional shape of the strips 200 shown is therefore essentially rectangular if the profiling of the side surfaces 205, 206 is disregarded. It is noticeable here that the profiling of the side surface 206 corresponds to the profiling of the frame outside 104 of the frame 102 of the frame formwork element 100 described above and the profiling of the side surface 205 is designed to be exactly the same. This means that the strips 200 can be coupled both to one another and to the frame 102 of the frame formwork element 100 .
- each of the strips 200 shown can be coupled to the frame 102 of the panel formwork element 101 of FIG. 1A.
- a first frame formwork system 300 according to the invention with two frame formwork elements 100 according to FIG. 1A and three battens 200 according to FIG. 2D can be seen in FIGS. 3A to 3C.
- the two panel formwork elements 100 are coupled to one another via the three strips 200 (see in particular FIGS. 3B and 3C).
- a length compensation can be achieved at the same time.
- the left strip 200 positively engages in the edge profile 101 of the left frame formwork element 100
- the right strip 200 together with the edge profile 101 of the right frame formwork element 100 forms two cavities 209 (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.
- a coupling can be achieved via the sealing elements, which counteracts a relative movement of the coupled elements.
- the frame formwork elements 100 each have a formwork skin 110 lying on the respective frame 102 and terminating flush with the edge protection 111 of the edge profiles 101 of the frame 102.
- FIGS. 4A to 4D further battens 200 for a panel formwork system 300 according to FIG. 3A are shown. These differ from one another by different widths b1 to b4, with each bar 200 having a variable width over the entire depth f of the bar. In the case of the strip 200 shown in FIG.
- the width b1 increases over the depth f, so that it has a width b1+ at the other end (the protruding geometries 201, 202 and the groove-forming stiffening beads 203, 204 are not taken into account when determining the width) .
- the strip 200 in FIG. 4C is designed analogously to the strip 200 in FIG. 4A, but overall has a smaller width b3, which increases towards the width b3+.
- the width b2 or b4 decreases to a width b2- or b4-.
- kinks and/or curvatures can be produced in the plane of the formwork skin 110, as shown by way of example in FIGS. 5A and 5B.
- a convex profile FIG. 5A
- a concave profile FIG. 5B
- the two strips 200 shown only one or more than two strips 200 can be used.
- different strips 200 can be used.
- FIGS. 6A and 6B Another preferred bar 200 for a panel formwork system 300 according to the invention can be seen in FIGS. 6A and 6B.
- the strip 200 serves to position a frame formwork element 100 and is arranged under the frame formwork element 100 or on the respective substructure for this purpose. Due to the changed position of the bar 200, the original width now corresponds to the height of the bar.
- the strip 200 is placed with the protruding geometries 201, 202 pointing upwards on the subsurface and is fixed in the subsurface with the aid of fastening means 211 in the form of screws (see FIG. 6C).
- the strip 200 has a lowered area 212 in the area of the protruding geometry 201 with an opening 210 designed as an elongated hole (see in particular FIG. 6B).
- the sunken area 212 ensures that the fastening means 211 does not protrude beyond the protruding geometry 201 of the strip 200 . Because this would impair the form fit between the strip 200 and the panel formwork element 100 .
- two such strips 200 can be arranged and fixed in a mirrored arrangement at a distance from one another on the substrate. The distance is predetermined by the thickness of the wall section to be produced.
- each Frame formwork element 100 are placed, so that the projecting geometries 201, 202 of the strips 200 engage in the corresponding groove-forming stiffening beads 105,106 of the respective frame formwork element 100.
- a positive fit is achieved between the strips 200 and the frame formwork elements 100, which prevents the concrete placed between the two frame formwork elements 100 from pushing them apart when concreting the wall section to be produced.
- the two strips 200 can be connected by means of drawstrings 213--as shown by way of example in FIGS. 8A to 8D.
- the drawstrings 213 each have at their two ends an opening 215 designed as a slot for receiving locking bolts 214 (see FIG. 8B), by means of which the drawstrings 213 can be connected to the strips 200.
- the fastening means 211 designed as a screw can also be used, with the aid of which the strip 200 can also be anchored in the ground.
- a preferred locking bolt 214 is shown by way of example in FIG. 9B. It has an elongate head 216 which, when inserted into the opening 215 of the drawstring 213, is aligned transversely to the longitudinal direction of the bar 200 and is then twisted so that it is aligned parallel to the longitudinal direction of the bar 200.
- the locking bolt 214 is inserted into an opening 210 of a lowered area 212 of the strip 200 in a manner analogous to the fastening means 211 (see FIG. 9A). This ensures that the locking bolt 214 does not protrude beyond the protruding geometry 201 of the strip 200 either.
- Rotating the locking bolt 214 so that the elongate head 216 is aligned parallel to the longitudinal direction of the bar 200 also ensures that it lags completely behind the projecting geometry 201 (see Figures 9C to 9E).
- the form fit between the strip 200 and the panel formwork element 100 is therefore not endangered.
- FIG. 10 shows a further frame formwork system 300 for producing a wall section in concrete construction.
- the frame formwork elements 100 are each positioned over the bottom strips 200 and kept at a distance which corresponds to the thickness of the wall section to be produced.
- the strips 200 are fixed to the substrate by means of fastening means 211 in the form of screws.
- the distance between the slats 200 is maintained by drawstrings 213 which are each connected to the slats 200 by means of locking bolts 214 .
- a plurality of anchor holes 109 are provided in the vertical rungs 108 of the frame 102 of the frame formwork elements 100 . These are also formed in the respective formwork skin 110 . Anchor tension rods 302 can thus be inserted into the anchor holes 109, by means of which two panel formwork elements 100 lying opposite one another can be clamped together (see, for example, FIG. 12).
- the frame formwork system 300 shown in FIG. 10 also has strips 200 for coupling two adjacent frame formwork elements 100.
- the coupling is effected in each case with the aid of two coupled strips 200 of different widths.
- FIG. 11 Another panel formwork system 300 is shown in FIG. 11, which largely corresponds to that of FIG. Here, however, two frame formwork elements 100 are coupled via three coupled strips 200 of different widths.
- the panel formwork elements 100 can be aligned vertically with the aid of an alignment support 301 and additionally supported.
- a centrally arranged anchor hole 109 of a panel formwork element 100 is also used an anchor tension rod 302, which serves to absorb horizontal loads.
- Further anchor tie rods 302 can be dispensed with, since both the floor-side strips 200 are connected via tie rods 213, as well as further strips 200 arranged on the panel formwork elements 100 (see in particular FIG. 13).
- FIG. 14 shows a panel formwork system 300 that has been increased.
- the panel formwork elements 100 are arranged not only next to each other but also one above the other.
- Strips 200 are again used for the coupling, with two strips 200 being arranged one above the other and being coupled to the panel formwork elements 100 .
- the lower bar 200 is connected to an opposite lower bar 200 via drawstrings 213, the upper bar 200 in a corresponding manner with an opposite top bar 200. With the help of the top bar 200, the panel formwork element 100 placed thereon can be positioned and held.
- the raised area is vertically aligned and supported by another prop 301.
