Description

The invention relates to a frame formwork element for a wall formwork system according to the preamble of claim 1.

The invention also relates to an insert part for a frame formwork element according to claim 20.

The invention also relates to a wall formwork system according to claim 21.

Furthermore, the invention relates to a method for producing a formwork system for forming parapets, foundations and beams according to claim 23.

Frame formwork elements are used as parts of formwork systems, in particular for the production of concrete components. The panel formwork elements are arranged in such a way that they form a mold into which a solidifiable building material, i. H. an initially liquid and then solidifying building material, usually concrete, is introduced to produce a component, for example a wall element. After the building material has hardened, the panel formwork elements are usually removed again.

Insofar as reference is made within the scope of the invention to concrete or a concrete component, it can also be a different solidifiable building material or a component made of another solidifiable building material.

The panel formwork elements have a frame to which the formwork panel or a formlining can be attached or attached.

On the one hand, the frame of the frame formwork elements should be stable in order to be able to transfer the loads occurring when the formwork system is filled with hardenable concrete. On the other hand, the frames should be sufficiently rigid to ensure high dimensional accuracy and to avoid unwanted deformation.

The structure of a surface of the concrete component facing the formwork panel is determined by the formwork panel attached to the frame. A front side of the formwork panel faces the concrete to be poured, ie the front side of the formwork panel forms the concrete-contacting surface, while the rear side of the formwork panel is attached to the frame.

Two panel formwork elements positioned opposite one another at a distance are connected or braced to one another by anchor devices. The known anchor devices have anchor rods. The tie rods pass through tie points or anchor bores in the frame formwork elements and in the formwork panels and are usually fixed with anchor plates or anchor fixations on a rear side of the frame formwork elements. The panel formwork elements known from the prior art are mostly made of metal, plastic or wood. The panel formwork elements usually have a rectangular basic construction.

A one-sided or double-sided anchoring technique can be used to brace the panel formwork elements.

The use of connecting locks is known from the prior art. The connection locks are also referred to as turnbuckles or alignment locks. Particularly advantageous connection locks are designed as so-called wedge locks.

The connecting locks are used to connect adjacent panel formwork elements flush, flush and tightly to one another. The connection locks can also be used to connect inside corners, outside corners, articulated corners and stop-end formwork.

The connecting locks are used in particular to brace a vertically running longitudinal frame part of a frame formwork element with an adjacent vertically running longitudinal frame part of another frame formwork element.

As a rule, connecting locks are arranged in the area where a horizontally running cross brace and a vertically running longitudinal frame part cross. The clamping jaws of the connecting lock encompass a section of the vertically running longitudinal frame parts of two panel formwork elements to be connected to one another. The two clamping jaws and thus the frame formwork elements can be braced against one another by means of a wedge, ie the clamping jaws are moved towards one another.

In a preferred embodiment of the connecting locks as wedge locks, it is provided that they have a traverse and a first clamping jaw, which is typically immovably connected to the traverse. Furthermore, the wedge locks have a second clamping jaw, the second clamping jaw being displaceable in a bracing direction along the longitudinal axis of the traverse in the direction of the first clamping jaw in order to brace the panel formwork elements.

A generic frame formwork element is from EP 0 047 550 B1 known. A rectangular panel formwork element is disclosed which has two longitudinal frame parts and two transverse frame parts. When the frame formwork element is correctly positioned for use, the longitudinal frame parts extend in the vertical direction, while the transverse frame parts run in the horizontal direction, ie transversely, on the upper and lower sides of the frame formwork element.

The longitudinal frame parts have passage bores through which tie rods are passed for bracing the frame formwork elements.

From the EP 0 047 550 B1 it is also known to define cross braces between the longitudinal frame parts. The cross braces run parallel to the frame cross members. The cross braces have two cross braces running parallel and at a distance from one another, between which a passage gap is formed for the passage of anchor rods.

This configuration makes it possible to pass anchor rods both through the passage openings in the longitudinal frame parts and through the passage gaps between the cross braces. Thus, tie rods can also be used between two longitudinal frame parts in order to fix the frame formwork elements at a distance from one another or to brace them against one another.

From the disadvantage of the from the EP 0 047 550 B1 However, the known solution is that the guidance of the tie rods, which extend through the passage gap, is insufficient. Furthermore, the sealing to the formlining is also insufficient, so that concrete poured between the panel formwork elements can leak out along the tie rods.

From the WO 2014/048908 A1 it is known to use a one-piece cross brace between the longitudinal frame parts, which has several bores for the passage of anchor rods. The ones from the WO 2014/048908 A1 Although the known solution improves the guidance of the tie rods due to the defined design of the bores in the cross brace, it has the disadvantage that the tie rods have to be fixed at the predefined points or in the specified grid, so that different pressure requirements and concrete patterns are not addressed can. Furthermore, the production costs of such a cross brace are comparatively high.

The cross braces known from the prior art are each arranged vertically offset one above the other, starting from a bottom cross brace. In the context of the invention, the term “lowermost cross brace” designates a cross brace which is arranged adjacent to and above the lower, horizontally running longitudinal frame part.

As a rule, the cross braces are each configured identically. However, it is also known from the prior art that, in order to reinforce the frame formwork element, a reinforcing element running in the vertical direction is introduced, preferably centrally between the two longitudinal frame parts running vertically. This reinforcement element can also only extend over part of the height, ie the vertical extension, of the frame formwork element. Furthermore, reinforcing elements extending in the vertical direction can also be used between the bottom cross brace and the lower, horizontally running frame cross part and between an uppermost cross brace and the upper, horizontal frame cross part.

The wall formwork systems known from the prior art have a plurality of panel formwork elements, which form formwork elements and counter formwork elements of the wall formwork system. The formwork elements and the counter formwork elements together form a filling space or a mold into which the solidifiable building material, usually concrete, is poured to produce a wall element.

The formwork elements and the counter formwork elements are also referred to as setting and closing formwork.

The formwork elements and the counter formwork elements can be of identical design. Within the scope of the invention, different terminology is only used to differentiate between the positioning of the formwork elements and the counter formwork elements.

The formwork elements and the counter formwork elements are also collectively referred to below as frame formwork elements.

There is a need to use different anchor devices, in particular due to different requirements for the concrete loads to be absorbed and also due to different local requirements or regulations and due to different working methods.

In the case of the known frame formwork elements in which the edge profile or the longitudinal frame parts are anchored, adaptation is not possible or only possible to a limited extent. In particular, the diameter of the anchor hole for receiving an anchor rod is fixed or limited to a maximum diameter. Furthermore, the anchor hole cannot be made arbitrarily large, since then anchor rods with a smaller diameter can no longer be adequately guided.

There is also a need to appropriately incline the tie rods that are passed through the tie bores of the tie points. With the existing anchor devices, this is only possible within certain limits that are fixed by the anchor point.

The anchor points are subject to increased wear and soiling due to the stress they are subjected to.

A disadvantage of the known anchor points is that cleaning them when they are dirty is time-consuming and the anchor points are also susceptible to repairs and replacing the anchor points is difficult or impossible.

It is also known from the prior art that anchoring is carried out next to the frame. For this purpose it is provided that holes in the formwork panel, d. H. the formwork skin, is introduced. The bores can easily be adapted to the circumstances or the requirements. However, such bores are difficult to seal, so that there is a risk that the concrete to be filled into the filling space will escape through the bores, as a result of which the frame formwork element will become correspondingly easily soiled. It is also a disadvantage that the inclination of the tie rod is not limited in the case of tie points that are only formed by a hole in the formwork panel, which means that there is a risk that an tie plate, in particular a nut joint plate, the longitudinal frame part of the frame formwork element or an the longitudinal frame part does not cover or does not reach or adequately cover the adjacent longitudinal frame part of a further frame formwork element, which is generally also to be braced.

Overall, it can be stated that in the case of the known panel formwork elements, the tie points limit the use of tie rods. As a result, in particular, the use of tie rods with particularly large diameters is not possible. Furthermore, the sealing of the anchor point is not always sufficient. Furthermore, it is difficult to repair and clean the anchor point, in particular the seal or seal. In addition, the inclination of the tie rod cannot be set in the desired manner or possibly cannot be limited.

Methods for producing a formwork system for forming parapets, foundations and beams are also known from the prior art. In order to create formwork systems for the formation of parapets, foundations and beams, it is common in the prior art that frame formwork elements are used that have a greater extent in the horizontal direction and a smaller extent in the vertical direction, since parapets, foundations and beams are usually have a maximum height of 1 m. The forces that occur are lower with such formwork systems because less concrete is poured into the filling space.

It is known from the prior art to use a perforated strap tensioner and a tension brace for anchoring or tensioning two spaced-apart frame formwork elements between which a filling space is formed. The tension strut connects the upper side of the two frame formwork elements to be braced with one another in such a way that the distance between the upper sides of the frame formwork elements cannot increase. In addition, under the underside of the two frame formwork elements, perforated strap tensioners are passed through, which are intended to prevent the frame formwork elements from moving away from each other on the underside. This method enables a stable construction of a formwork system for the formation of parapets, foundations and beams. However, the method has the disadvantage that the passage of the perforated strap tensioner below the two panel formwork elements is an unpleasant activity, since the panel formwork elements are on the ground and carrying out this activity, particularly depending on the weather, can be tedious and can result in corresponding soiling leads.

It is also known from the prior art to produce a formwork system for forming parapets, foundations and beams, to use special frame formwork elements in which another horizontally running frame part is placed centrally between the frame parts running horizontally on the top and bottom hereinafter referred to as reinforcement part, runs. In this case, anchor bores are made in the reinforcement part, through which anchor rods of anchor devices can be passed. This solution makes it possible to use perforated strap tensioners on the underside of the yard to dispense with humane elements. Tension-compression braces are used on the upper side of the frame formwork elements, which are designed in such a way that the upper frame parts of the frame formwork elements to be braced together are held in position relative to one another, so that they can neither move further away from one another nor towards one another. Since no perforated strap tensioners are used on the underside of the panel formwork elements, if no push-pull braces are used on the top, there could be a risk of the panel formwork elements being pushed apart on the underside and the frame parts on the top moving towards one another. This is prevented by the tension-compression braces.

Frame formwork elements with a reinforcement part can also be used to reliably create formwork systems for forming parapets, foundations and beams. However, there is the disadvantage that special frame formwork elements are required for this and the use of anchor devices, in particular the use of anchor rods, is also limited since the size of the anchor bore in the reinforcement part or the anchor point formed there limits the diameter of the anchor rods that can be used . Furthermore, the anchor rods often cannot be inclined in the desired manner. Furthermore, repairing the anchor point and cleaning it is difficult.

There is therefore a need to improve the known methods for producing a formwork system for forming parapets, foundations and beams.

The object of the present invention is to solve the disadvantages of the prior art, in particular to create a panel formwork element which has an anchor point which can be easily adapted to different diameters of anchor rods and which can be easily cleaned and repaired.

This object is achieved by claim 1 according to the invention.

The present invention is also based on the object of creating a wall formwork system having a plurality of panel formwork elements which have an anchor point which can be easily adapted to different diameters of anchor rods and which can be easily cleaned and repaired.

According to the invention, this object is achieved by claim 21 .

Furthermore, the present invention is based on the object of creating a method for producing a formwork system for forming parapets, foundations and beams that is inexpensive and makes it possible to set up a formwork system quickly and easily.

This object is achieved by claim 23 according to the invention.

The frame formwork element according to the invention for a wall formwork system has a frame and a formwork panel which can be attached to the frame and is also referred to as formwork skin. Furthermore, the panel formwork element according to the invention has a plurality of anchor points, each with an anchor hole for passing through an anchor rod of an anchor device. The frame of the panel formwork element has two longitudinal frame parts running vertically, a lower transverse frame part running horizontally and an upper transverse frame part running horizontally. A plurality of cross braces is fixed between the longitudinal frame parts, with the cross braces being arranged vertically offset one above the other, starting from a bottom cross brace, and the cross braces running parallel to the frame cross parts.

According to the invention, at least one of the anchor holes is formed in an insert part, the insert part being detachably fixed in the area of a crossing between one of the longitudinal frame parts and one of the cross braces to form an anchor point.

Within the scope of the invention, the insert part is designed separately from the frame and can be releasably connected to it.

The fact that the anchor bore is formed in an insert part which is detachably fixed in the area of a crossing between one of the longitudinal frame parts and one of the cross braces to form an anchor point results in considerable advantages over the prior art.

The solution according to the invention makes it possible to exchange the anchor points or the anchor bores, so that the anchor bores can be adapted to the respective application, the technical requirements or local requirements. It is possible, for example, that in countries in which the anchor devices have anchor rods with a larger diameter, an insert part with a correspondingly large anchor hole for forming an anchor point is detachably fixed to the panel formwork element.

Furthermore, it is also possible that anchor bores are used, which make it possible to fix the anchor rod with a desired inclination, whereby the maximum possible inclination can also be determined by the anchor bores.

The formation of the anchor hole in an insert part, which can be detachably connected to the frame formwork element, also enables a quick and easy change for repair or cleaning purposes. The solution according to the invention thus makes it possible to provide the frame formwork element with a respectively suitable insert part, which can serve as an interchangeable insert, so that the frame formwork element has a suitable anchor hole. The panel formwork element can thus be easily adapted to different purposes. The insert part can be replaced without having to change the formwork panel. This is a decisive advantage, especially for repair work. On construction sites, the anchor bore can regularly become dirty or mechanically damaged. With the solution according to the invention, a simpler and quicker replacement is now possible.

The insert part is arranged in the frame formwork element in such a way that the anchor hole in the insert part is aligned with a hole in the formwork panel and seals it on the side facing away from the filling space in such a way that it is avoided or largely avoided that the building material to be filled into the filling space is prevented unwanted exit.

According to the invention, it can be provided that the insert part is arranged in the area where one of the cross braces and one of the longitudinal frame parts crosses in such a way that an anchor plate of the anchor device, the anchor rod of which is passed through the anchor bore of the insert part, rests both on the cross brace and on the longitudinal frame part if the panel formwork element is braced with another panel formwork element of the wall formwork system.

An arrangement of the insert such that an anchor plate of the anchor device bears against both the cross brace and the longitudinal frame part has proven to be particularly suitable, since the anchor plate rests stably and tilting of the anchor plate is prevented. The position of the insert part in the area of the intersection between one of the cross braces and one of the longitudinal frame parts is preferably selected in such a way that the anchor plate not only bears against the longitudinal frame part of the frame formwork element to which the insert part is fixed, but also against a longitudinal frame part adjoining this longitudinal frame part additional panel formwork element. The two panel formwork elements are preferably connected to one another by means of a bracing lock.

It has been shown that a particularly suitable abutment for the anchor plate of an anchor device results when it rests against two adjacent frame longitudinal parts of two frame formwork elements and against one of the cross braces.

In conjunction with the possibility that the anchor bore in the insert part is preferably designed in such a way that an anchor rod can run inclined or the inclination of the course of the anchor rod can be adjusted, a particularly precise fixing results. The tie rod is inclined relative to an orthogonal line of the formwork panel.

The anchor plate is preferably designed as a nut joint plate.

It is advantageous if at least two, preferably four or six insert parts are releasably fixed in the region of one of the intersections between one of the longitudinal frame parts and one of the cross braces.

The insert parts are preferably assigned in pairs to one of the cross braces.

It has turned out to be particularly suitable if several insert parts are fixed to the frame formwork element, each in the region of one of the crossings between one of the longitudinal frame parts and one of the cross braces.

It has turned out to be advantageous if a majority of the anchor points of the frame formwork element, preferably all anchor points of the frame formwork element, are formed by the insert part according to the invention. Depending on the compressive forces to be absorbed, it may be sufficient if two, four or six insert parts are releasably fixed in the area of one of the crossings between one of the longitudinal frame parts and one of the cross braces. In addition, the panel formwork element preferably has no further anchor points.

According to the invention can also be provided that two insert parts are assigned to one of the cross braces, such that in each case in the region of a crossing between one of the two axial ends of the cross brace and one of the adjacent longitudinal frame parts each insert part is detachably fixed.

It has proven to be suitable if two insert parts are assigned to a cross brace and the insert parts are each detachably fixed adjacent to one of the longitudinal frame parts at the axial ends of the cross brace.

It is advantageous if the insert part is fixed in the area of a crossing between one of the longitudinal frame parts and one of the cross braces in such a way that a longitudinal axis of the anchor hole in the insert part is essentially orthogonal to the formwork panel.

An arrangement of the insert part such that the longitudinal axis of the anchor bore in the insert part runs essentially orthogonally to the formwork panel, preferably an inclination to the orthogonal is less than 10 degrees, preferably less than 5 degrees, has proven to be particularly suitable for placing the anchor rod in used and managed appropriately.

The anchor hole can preferably be designed in such a way that the anchor rod passed through the anchor hole can be inclined relative to the orthogonal, preferably by a maximum of 20°, in particular by a maximum of 10°.

In principle, the anchor hole can have any desired design, for example it can be provided that the anchor hole is a cylindrical hole with a substantially uniform diameter along the longitudinal axis of the anchor hole.

It is advantageous if the anchor hole tapers, preferably conically, in the direction of the formwork panel.

It has turned out to be particularly suitable if the anchor hole tapers in the direction of the formwork panel. This makes it possible, on the one hand, to align or incline the tie rod in the desired way, and on the other hand, the tapering area in the direction of the formwork panel makes it easier to clean the tie point and prevents the panel formwork element from filling up with the concrete to be poured into the filling space .

Alignment or inclination of the tie rod can be particularly advantageous if an oppositely positioned frame formwork element, with which the frame formwork element is to be anchored, is not exactly positioned or there is an offset in height or in a horizontal direction. In this case, it is advantageous if the anchor rod of the anchor device can be aligned accordingly.

It can be advantageous if an exit opening of the anchor hole facing the formwork panel has a diameter that corresponds as far as possible to the diameter of the anchor rod, so that the exit opening facing the formwork panel is sealed as well as possible. The outlet opening preferably also corresponds to the diameter of the bore in the formwork panel. The exit opening and the bore in the formwork panel are preferably arranged coaxially to one another.

It is advantageous if an outlet opening of the anchor hole facing the formwork panel has a smaller diameter than an inlet opening of the anchor hole facing away from the formwork panel.

The anchor hole preferably tapers evenly in the direction of the formwork panel.

It has proven to be particularly suitable if the anchor hole is conical and tapers in the direction of the formwork panel, ie in the direction of the exit opening of the anchor hole.

According to the invention, it can also be provided that an outlet opening of the anchor hole facing the formwork panel has a circular diameter and/or an inlet opening of the anchor hole facing away from the formwork panel has an oval diameter.

It has turned out to be particularly suitable if the inlet opening of the armature bore has an oval diameter, with which an armature inclination in a specific direction can be limited or made possible. It is particularly advantageous if the oval diameter is designed in such a way that the longer axis of the oval diameter runs essentially parallel to the longitudinal frame part, i.e. extends in a vertical direction, when the frame formwork element is correctly positioned when used in a wall formwork system .

The inventor has recognized that in practice an adjustment of the inclination of the anchor rod is particularly advantageous in order to compensate for a height offset between two panel formwork elements that are to be anchored to one another. In addition, it can also be an advantage if the tie rod can compensate for a horizontal offset, but this is usually less than an offset in the vertical direction, which is why it is advantageous if the oval diameter of the entrance opening of the anchor bore is designed in such a way that the anchor rod has greater play in the vertical direction.

According to the invention, it can also be provided that the insert part and/or the anchor hole has a length that corresponds to at least 50% of the depth, preferably essentially the depth of the cross brace and/or the depth of the longitudinal frame part in the area of the crossing.

It has proven to be suitable if the insert part and/or the anchor hole has a length that corresponds to at least 50% of the depth of the cross brace and/or the depth of the longitudinal frame part in the area of the crossing. The length of the insert part or the length of the anchor hole preferably corresponds essentially to the depth of the cross brace or the longitudinal frame part. The depth of the cross brace and the depth of the longitudinal frame part is usually identical. The depth of the cross brace and the depth of the longitudinal frame part also specify the depth of the frame formwork element (without the formwork panel), ie the extent of the frame formwork element orthogonally to the formwork panel. The length of the anchor hole or the length of the insert part is therefore to be understood as meaning a length that extends in a direction orthogonal to the formwork panel.

The aforementioned configuration of the insert part and/or the anchor hole in the insert part enables a particularly advantageous guidance of an anchor rod and also provides a particularly advantageous seal with respect to the formwork panel.

According to the invention, it can also be provided that for fixing the insert part in the area of the intersection, a pocket is provided, preferably formed in one piece with the cross brace and/or the longitudinal frame part, into which the insert part can be releasably inserted.

In a particularly advantageous embodiment of the invention, it is provided that a pocket is formed in the area where one of the cross braces and one of the longitudinal frame parts intersect, into which the insert part can be inserted in a detachable manner.

The pocket is preferably formed in one piece with the cross brace and/or the longitudinal frame part or is connected in one piece to the frame. The pocket is thus preferably made of the same material as the frame, for example metal, in particular steel. It is preferably a steel bag.

The bag can also be designed as a plastic bag and connected to the frame, e.g. also a metal frame.

The pocket makes it possible in a particularly simple manner to fix the insert in a detachable manner, so that the insert can be exchanged in a particularly simple manner.

The pocket is preferably designed in such a way that the insert part can be inserted into it. The pocket can preferably have side walls which extend orthogonally to the formwork panel and which preferably cover corresponding side surfaces of the insert part which also extend orthogonally or substantially orthogonally to the formwork panel.

The pocket preferably has closed side surfaces, but the side surfaces can also have openings or be designed as a grid with openings.

The pocket can have any inner diameter or interior space, for example with a rectangular, polygonal, square or even cylindrical cross section. The pocket can also be designed in such a way that the interior or the inner diameter tapers in the direction of the formwork panel.

The insert part has an outer circumference which is preferably adapted to the interior of the pocket, in particular the side surfaces of the insert part are preferably adapted to the course of the inner surfaces of the pocket.

The insert can have a cylindrical, rectangular, polygonal or square cross-section. The cross section is to be understood in such a way that it extends plane-parallel to the formwork panel.

The insert is preferably formed such that it has a length extending in a direction orthogonal to the form panel that is greater than a height, i. H. an extension parallel to the frame lengths when the insert is inserted into the pocket and is greater than a width, d. H. an extension parallel to the frame cross members.

It is advantageous if the pocket and the insert are adapted to one another in such a way that the insert can be inserted into the pocket in a form-fitting manner.

It has turned out to be particularly suitable if the insert part can be inserted into the pocket in a form-fitting manner.

It is also advantageous if the insert part is detachably secured in the pocket by latching, clipping, screwing or nailing.

A detachable fixing of the insert in the pocket by means of latching elements, clips, screws or nails, although mixtures of these are also possible, has proven to be particularly suitable for reliably fixing the insert on the one hand, in particular in such a way that the insert part forms part of the formwork panel seals out, as well as to be able to quickly release the insert part again if necessary.

According to the invention, it can be provided that the insert part has projections, latching lugs or the like, which can penetrate into corresponding complementary depressions in the pocket. It is also possible that the insert part has indentations and the pocket has corresponding locking lugs or the like.

It is advantageous if a front, open end of the pocket is adjacent to the formwork panel and the pocket has a rear, open end into which the insert can be inserted, with the insert preferably being able to be inserted into the pocket to such an extent that a front end of the insert on the formwork panel.

The aforementioned design of the bag has turned out to be particularly suitable. It is preferably provided that the pocket and the insert part are also designed in such a way that a rear end of the insert part runs essentially flush in a plane with the rear end of the pocket when the insert part is inserted into the pocket so far that a front end of the insert rests against the formwork panel.

The insert part described above, which is inserted into a pocket, has proved to be particularly suitable. However, the invention is not limited to this. To form an anchor point, the insert part can also be detachably fixed in some other way in the area of a crossing between one of the longitudinal frame parts and one of the cross braces. A further advantageous embodiment to enable such a setting is presented below.

According to the invention, it can be provided that the insert part has positioning aids, with which the insert part can be positioned and releasably fixed in the area of the intersection on one of the cross braces and one of the longitudinal frame parts.

Because the insert part has positioning aids, the insert part can be fixed laterally to one of the longitudinal frame parts and one of the cross braces in a particularly simple manner. The insert part is preferably designed in such a way that it is inserted into a corner between the cross brace and the longitudinal frame part, preferably in such a way that a side surface of the insert part borders the cross brace, and a side surface of the insert part running at right angles thereto borders a side surface of the longitudinal frame part. The insert part is preferably positioned and fixed both with the cross brace and with the longitudinal frame part with the aid of positioning aids. The positioning aids can preferably be in the form of projections, latching lugs or springs which can be inserted into corresponding depressions in the longitudinal frame part and/or the cross brace in the area of the crossing. Alternatively, the longitudinal frame part and/or the cross brace can also have projections, latching lugs or springs which engage in corresponding depressions in the insert part.

In a simple embodiment, the positioning aids can also just be markings or bores. The positioning aids can also be screws, nails or bolts, with the help of which the insert part is positioned and fixed on the longitudinal frame part and/or the cross brace.

According to the invention it can be provided that the insert part is made of plastic, wood or metal.

It has turned out to be particularly suitable if the insert part is made of plastic.

According to the invention it can be provided that the frame of the frame formwork element is made of metal, plastic or wood.

It has turned out to be particularly suitable if the frame is made of metal and the insert part is made of plastic.

Since the insert part is formed separately from the frame, a suitable mix of materials can be selected in an advantageous manner; in particular, a frame made of metal can be combined with an insert part made of plastic or wood.

It is advantageous if two insert parts, each in the region of the intersection with one of the adjacent longitudinal frame parts, are releasably fixed to a bottom cross brace or to a second-lowest cross brace, preferably adjacent to its top side.

Tests have shown it to be particularly suitable if two insert parts are detachably fixed to a lowermost cross brace or to a second-lowest cross brace. A bracing lock is preferably fixed to the respective other cross brace, which is used to brace two frame formwork elements that are laterally adjacent to one another.

It has turned out to be particularly suitable if the anchor point is formed on the lowest cross brace and a connecting lock is fixed on a second-lowest cross brace.

It is advantageous if two insert parts are also fixed to a further, preferably two further, cross braces.

The inserts are preferably secured adjacent a top of the lowest cross brace or adjacent a top of the second lowest cross brace. The top is a surface that faces away from the lower frame cross member and that extends orthogonally to the formwork panel.

It is advantageous if two insert parts, each in the region of the intersection with one of the adjacent longitudinal frame parts, are detachably fixed to an uppermost cross brace or to a second uppermost cross brace, preferably adjacent to its underside.

It has turned out to be particularly suitable if two insert parts are attached to an uppermost crossbar or to a second-top crossbar. This, in particular, in combination with the fact that two insert parts are also fixed to a bottom cross brace or to a second bottom cross brace.

It can be particularly advantageous if the two insert parts are detachably fixed adjacent to an underside of the uppermost cross brace or adjacent to an underside of the second uppermost cross brace. The underside is a surface of the cross brace that faces away from an upper frame cross member and that extends orthogonally to the formwork panel.

It is advantageous if the insert part is fixed to an uppermost cross brace or to a cross brace second from the top and a connecting lock is fixed to the respective other cross brace.

It is also advantageous if two insert parts are detachably fixed to a fourth-lowest cross brace or to a fifth-lowest cross brace, each in the region of the intersection with one of the adjacent longitudinal frame parts, preferably in a pocket between the cross brace and the longitudinal frame part.

It has proven to be particularly suitable if two inserts are fixed to a fourth-lowest or fifth-lowest cross brace. This solution is particularly useful in combination with the fact that two insert parts are each fixed to a bottom or second-bottom cross brace and to a top or second-top cross brace.

The inserts can be fixed adjacent to an underside or adjacent to an upper side of the fourth-lowest or fifth-lowest cross brace. A particularly suitable embodiment can result if a pocket is formed between the cross brace and the associated longitudinal frame part, in which pocket the insert part can be releasably fixed.

In the described configuration of fixing two insert parts on the bottom cross brace or the second-lowest cross brace or on the top cross brace or the second-top cross brace, it can be advantageous if one pocket is formed.

It is advantageous if a set comprising a plurality of insert parts is provided, with the set of insert parts having at least insert parts of a first type and insert parts of a second type, the outer contour of which is identical to the extent that it is necessary for detachable attachment to the frame formwork element and which are suitable for connection to the same frame formwork element, the insert parts of the first type and the second type differing at least with regard to the design, in particular the diameter and the course of their anchor holes and/or their color design.

It has turned out to be particularly suitable if the frame formwork element has a set of several insert parts and the set has at least insert parts of a first type and a second type and preferably also of a third, fourth or further type. The insert parts are identical in terms of their outer contour or at least identical to the extent that they can each be inserted into identical pockets or have identically designed positioning aids in order to position them laterally on a cross brace exercise and an associated longitudinal frame part. The different types of insert parts differ at least with regard to the design of their anchor holes, in particular the diameter or the course of their anchor holes and/or their color design.

It can thus be provided that a first type of insert parts each have anchor bores with an identical design. It can be provided that insert parts of a second type each have identical anchor bores, but their design differs from the design of the anchor bores of the insert parts of the first type, for example with regard to their course, for example with regard to the conicity and/or the diameter. It can also be advantageous if the insert parts of the different types have different colored designs, for example an insert part of the first type can have a different color than an insert part of the second type. This has the technical effect that due to the colored design of the insert part can be recognized what the corresponding frame formwork element is suitable, in which the insert is used. A technical use or a local use can be derived from this, for example. This has the advantage that the frame formwork elements can basically be of identical design and different uses can be derived from the color design of the insert parts.

In this case, it can be provided that insert parts which have a different design of the anchor bores also have different colors.

An advantageous insert for forming an anchor point in a frame formwork element results from claim 20.

An advantageous wall formwork system results from claim 21.

The wall formwork system according to the invention has a plurality of panel formwork elements according to one of Claims 1 to 19 or as described above. The frame formwork elements form formwork elements and counter formwork elements of the wall formwork system. Between the formwork elements and the counter formwork elements there is a filling space for receiving a solidifiable building material. A plurality of anchor devices is provided in order to brace a first formwork element with a first counter formwork element. One of the longitudinal frame parts of the first formwork element borders on one of the longitudinal frame parts of a second formwork element.

The use of the panel formwork elements according to the invention to form a wall formwork system results in a particularly advantageous wall formwork system which makes it possible in particular to compensate for deviations in the height direction or in the horizontal direction between a first formwork element and a first counter formwork element.

The formwork elements and the counter formwork elements of the wall formwork system according to the invention are at least partially, preferably mostly, designed as frame formwork elements according to the invention. All formwork elements and counter-formwork elements are preferably designed as frame formwork elements according to the invention. However, frame formwork elements of a different design can also be used in the wall formwork system.

It is advantageous if the insert part is arranged in the area where one of the cross braces and one of the longitudinal frame parts cross in such a way that an anchor plate of the anchor device whose anchor rod is passed through the anchor hole of the insert part, both on the cross brace and on the two adjacent frame longitudinal parts of the first formwork element and the second formwork element rests in order to brace the first formwork element and the second formwork element with at least the first counter formwork element.

It has proven to be particularly suitable if the insert is positioned in such a way that an anchor plate of the anchor device rests against both the associated cross brace and the two adjacent longitudinal frame parts of the first formwork element and the second formwork element.

It has turned out to be advantageous if the formwork elements and the counter formwork elements each have eight cross braces and preferably a height of 260 cm to 280 cm, preferably 270 cm. Provision is preferably made for two insert parts to be detachably fixed to a lowermost cross brace or to a second-lower cross brace, in each case in the region of the intersection with one of the adjacent longitudinal frame parts. Provision is preferably also made for two insert parts, each in the area of the intersection, to be detachably fixed to one of the adjacent longitudinal frame parts on an uppermost cross brace or on a second uppermost cross brace. No further inserts are preferably provided. It is advantageous if, on a cross brace that is arranged adjacent to the cross brace, on the two ones parts are specified, a connecting lock for connecting the first formwork element to an adjacent second formwork element is arranged.

Connecting locks are preferably fixed to two cross braces and two insert parts are fixed to two cross braces.

In a further constructive embodiment, it has also turned out to be advantageous if the formwork elements and the counter formwork elements each have nine cross braces and preferably a height of 280 cm to 320 cm, preferably 300 cm. The inserts can preferably be fixed in such a way as was shown above using a formwork element and a counter-formwork element, each with eight cross braces, it also being possible for two insert parts to be attached to a fourth-lowest cross brace or a fifth-lowest cross brace, each in the area of the intersection with a the adjacent longitudinal frame parts, are detachably fixed.

Furthermore, it can be provided that a connecting lock is fixed to a cross brace that runs adjacent to a cross brace on which two insert parts are fixed. Preferably, connecting locks are fixed to three cross braces and two insert parts are fixed to three cross braces.

An advantageous method according to the invention for producing a formwork system for forming parapets, foundations and beams results from claim 23.

The method according to the invention for producing a formwork system for forming parapets, foundations and beams provides that a plurality of formwork elements and a plurality of opposing formwork elements are positioned relative to one another in such a way that a filling space for receiving a solidifiable building material is formed between the formwork elements and the opposing formwork elements. according to which a plurality of anchoring devices are used to brace a first formwork element to a first counter-formwork element, and after which the first formwork element is braced to an adjacent second formwork element by means of at least one connecting lock.

According to the invention, frame formwork elements of wall formwork systems are used for the formwork elements and the opposing formwork elements, which frame formwork elements have a frame with two longitudinal frame parts, a lower transverse frame part and an upper transverse frame part, with a plurality of transverse struts being fixed between the longitudinal frame parts, which are each offset from one another and run parallel to the frame transverse parts, after which the frame formwork elements are used in order to use them as formwork elements and as counter-formwork elements for the formation of parapets, foundations and beams, in such a way that the two longitudinal frame parts run horizontally and the two frame transverse parts and the cross braces run vertically in the formwork system, after which an overhead longitudinal frame part of the first formwork element and an overhead longitudinal frame part of the first opposing formwork element are connected by means of at least one push-pull brace n and additionally in order to brace the first formwork element and the first counter-formwork element with one another by means of at least one anchoring device, below half the height of the first formwork element and the first counter-formwork element in the respective formwork panel, adjacent to one of the frame cross parts or one of the cross braces, each with a hole for passage an anchor rod of the anchor devices is introduced.

The method according to the invention makes it possible to produce formwork systems for forming parapets, foundations and beams in a particularly advantageous manner. It can be particularly suitable for this if frame formwork elements of wall formwork systems are used for the formwork elements and the opposing formwork elements of the formwork system for forming parapets, foundations and beams, which are designed according to the frame formwork elements, as described above. However, the method according to the invention for producing a formwork system for forming parapets, foundations and beams is not limited to the use of such panel formwork elements. In principle, all known frame formwork elements of wall formwork systems are suitable for use according to the invention in such a way that they serve as formwork elements and counter formwork elements for producing a formwork system for forming parapets, foundations and beams.

The height of the known frame formwork elements of wall formwork systems is generally greater than their width, ie the longitudinal frame parts are longer than the transverse frame parts. The known panel formwork elements are now aligned in such a way, in particular tilted by 90°, that the longitudinal frame parts are now in a horizontal position Run direction and the frame cross members in the vertical direction. Thus, the cross braces also run in the vertical direction.

Formwork systems for forming parapets, foundations and beams typically have a height of less than 120 cm, which is why the width of a panel formwork element of wall formwork systems is particularly suitable as a formwork element or counter-formwork element for formwork systems for forming parapets, foundations and beams to find use.

In order to clamp the formwork elements and the opposing formwork elements together or to keep them in position to form a filling space, perforated strap tensioners were necessary in the prior art, as described, or special frame formwork elements had to be used that had a corresponding special frame construction so that anchor devices could be set be able. The method according to the invention makes it possible in a simple manner to use conventional panel formwork elements of wall formwork systems, preferably such as have been described in the context of the invention. For this purpose, an overhead longitudinal frame part of the first formwork element and an overhead longitudinal frame part of the first opposing formwork element are connected by means of at least one tension/compression brace. The tension-compression braces are designed in such a way that they prevent the longitudinal frame part of the first formwork element lying on top from approaching as well as moving away from the longitudinal frame part of the first opposing formwork element lying on top. This can be achieved by corresponding projections or by corresponding latching elements which are designed in the push-pull strut such that the overhead longitudinal frame parts of the first formwork element and the first counter-formwork element are immovably connected to one another in the axial direction of the push-pull strut.

In addition, within the scope of the method according to the invention, it is only provided that below half the height of the first formwork element and the first counter-formwork element in the respective formwork panel, adjacent to one of the frame cross parts or one of the cross braces, a borehole for passing through an anchor rod of the anchor device is drilled. The feature "below half the height" is to be understood as meaning the height of the formwork element or the counter formwork element when they are positioned as intended for the construction of a formwork system for the formation of parapets, foundations and beams. i.e. the height of the formwork element or of the counter formwork element extends orthogonally to the extent of the transverse frame part and thus in the vertical direction. It has been shown that drilling holes below half the height of the formwork element and the counter-formwork element is advantageous, since this reliably prevents the formwork element and the counter-formwork element from being pushed apart in the lower region when the filling space is filled with the building material to be solidified is filled.

The bores are preferably made in the lower third of the height of the first formwork element and the first counter formwork element. Provision is made for a borehole in the counter-formwork element to be aligned with a borehole in the formwork element, so that an anchor rod can be passed through.

The inventor has recognized that there is no disadvantage here if the anchor points are only formed by bores in the formwork panels. Due to the lower concrete pressure in such formwork systems, there are no major problems with sealing.

According to the invention, it can be provided within the scope of the method that at least two tension-compression struts and at least two anchor devices are used to connect the first formwork element to a first counter-formwork element, and the anchor bores for the anchor rods are each below half the height of the first formwork element and the first Counter-formwork elements are introduced into the respective formwork panel adjacent to one of the cross-frame parts.

It has turned out to be particularly advantageous if exactly two tension-compression braces and two anchoring devices are used to connect the first formwork element to the first opposing formwork element. The tension-compression struts are preferably arranged in such a way that they are positioned in a crossing area of an overhead longitudinal frame part and a transverse frame part. The bores for the anchor rods, which are made in the formwork panels of the formwork elements or the counter formwork elements, are preferably located adjacent to one of the transverse frame parts.

Features that have been described in connection with the frame formwork element according to the invention can of course also be advantageously implemented for the wall formwork system according to the invention, the insert part and the method according to the invention - and vice versa. Furthermore, benefits already associated with the panel formwork element according to the invention are also understood to refer to the wall formwork system according to the invention, the insert part and the method according to the invention - and vice versa.

In addition, it should be noted that terms such as "comprising", "having" or "with" do not exclude any other features or steps. Furthermore, terms such as "a" or "that" which indicate a singular number of steps or features do not exclude a plurality of features or steps - and vice versa.
