Definitions
- the invention relates to a shuttering element for shuttering a part of a building, comprising a shuttering frame and at least one shuttering skin, which is connected to the shuttering frame and which, when used, rests against a part of the building to be erected with a shaped surface, with an edge running around the shaped surface.
- the formwork element also comprises at least one sealing profile, which is arranged between the formwork facing and the formwork frame, the formwork frame having a bearing surface on which the formwork facing rests in certain areas when used and the formwork frame also having a frame edge which is arranged adjacent to the bearing surface and this at least in some areas, the frame edge protruding in a direction perpendicular to the bearing surface over the bearing surface and the sealing profile being arranged at least in some areas between the frame edge and the edge of the formwork skin surrounding the mold surface.
- the invention further relates to a method for assembling a formwork element.
- Formwork is used to produce parts of a building, such as walls or ceilings. Such formwork is constructed in such a way that the negative form of a part of the building to be erected is created inside. A concrete material is then poured into the formwork, which forms the part of the building after it has hardened. In the last step, the formwork is removed from the part of the building and can preferably be used to construct other parts of the building.
- a formwork is usually made up of several formwork elements. Such a formwork element usually comprises a frame which absorbs the forces acting on the formwork element from the cast-in concrete material. The actual interface between the formwork element and the concrete material forms a formwork skin, which is inserted into the formwork frame.
- the object of the invention is therefore to propose solutions with which the sealing of the formwork frame of a formwork element to a formwork skin inserted in the formwork frame can be improved.
- a formwork element for forming part of a building comprising
- - at least one formwork panel which is connected to the formwork frame and which, when used, bears against a part of the building to be erected with a shaped surface, with an edge running around the shaped surface
- - at least one sealing profile which is arranged between the formwork skin and the formwork frame and in particular connects the edge of the formwork skin surrounding the mold surface to the formwork frame in a sealing manner, wherein the sealing profile, which extends along a direction of extension, comprises the following elements:
- the sealing body which at least partially consists of an elastic material
- the sealing body has at least two contact surfaces which bear against the formwork frame and/or the formlining at least partially, wherein the contact surfaces are arranged on opposite sides of the sealing body and are each parallel to the extend in the direction of extension, and wherein each of the contact surfaces is larger than the end faces of the sealing body arranged between the contact surfaces, wherein the sealing body has at least two sealing surfaces, one of which forms a partial area of a contact surface,
- the formwork frame having a bearing surface on which the formwork skin rests in certain areas in the application and the formwork frame furthermore has a frame edge which is arranged adjacent to the bearing surface and runs around it at least in regions, the frame edge protruding in a direction perpendicular to the bearing surface over the bearing surface and the sealing profile being arranged at least in regions between the frame edge and the edge of the formwork skin surrounding the shaped surface and a surface of the frame edge facing in the direction of the formlining is arranged at an angle different from 90° to the supporting surface and/or the edge is arranged at an angle different from 90° to the supporting surface.
- a formwork element according to the invention is intended to form a partial area of a formwork for the production of a part of a building.
- the formwork element according to the invention comprises a formwork frame, a formwork skin and a sealing profile arranged between them, which seals the formwork frame to the formwork skin.
- the sealing profile is already in the solid state during assembly of the formwork element, ie not in the liquid state.
- the effect of the formwork element according to the invention results from the shape of the sealing profile in interaction with the adjacent elements of the formwork frame and the formlining.
- the formwork frame forms the load-bearing component of the formwork element and carries other elements of the formwork element, such as the formlining.
- the formwork frame absorbs the loads acting on the formwork element. Such loads can be caused, for example, by the pressure of a concrete material filled into the formwork.
- the formwork element also includes a formwork skin, which forms the largest part of the surface with which the formwork element bears against a part of the building to be erected.
- the formwork facing has a shaped surface facing the concrete material. In most cases, the mold surface is flat.
- the formwork element according to the invention also includes a sealing profile which is positioned in a sealing manner between the formwork skin and the formwork frame.
- a sealing profile is to be understood as meaning a seal which extends in a direction of extent with a defined cross section.
- the sealing profile has its longest dimension along the direction of extension.
- the cross section of the sealing profile can be constant along the direction of extension or can change along the direction of extension.
- the shape and size of the cross section of the sealing profile are preferably at least regular along the direction of extent.
- the weatherstrip may be provided on a roll or spool, in which case the weatherstrip is wound spanwise around the roll or spool.
- the sealing profile can be cut to the required lengths and installed during assembly of the formwork element.
- the sealing profile comprises several elements: the sealing profile comprises a sealing body, which consists at least partially of an elastic material. It is also possible for the entire sealing body to consist of an elastic material.
- the elastic material is elastically deformed during assembly of the formwork element and thus reliably fills the space between the formlining and the formwork frame.
- the sealing body can also include elements made of non-elastic material, for example elements which shape the sealing body stabilize, such as inserted metal wires.
- further elements can be arranged in the sealing body, for example sensors.
- the sealing body comprises at least two contact surfaces, one of which rests on the formwork frame and the other on the formwork facing.
- the two contact surfaces are arranged on opposite sides of the sealing body and are connected to one another by two end faces, the end faces in turn being arranged on opposite sides of the sealing body.
- the two contact surfaces and the two end faces extend along or parallel to the direction of extension of the sealing profile.
- the two contact surfaces are larger than the two end faces of the sealing body.
- partial areas of the two contact surfaces each form a sealing surface which rests sealingly either on the formwork frame or on the formwork skin. When the sealing profile is installed, it is not necessary for the entire contact surfaces to rest against the formwork frame or the formlining.
- the sealing profile also includes a fastening element which is connected either to the formwork frame or to the formwork skin. Furthermore, the fastening element is firmly connected to the sealing body. The fastening element is preferably arranged on one of the two contact surfaces.
- the fastening element can be designed in different ways, for example as an adhesive surface or as a projection on the sealing body, which is provided for a positive or non-positive connection with the formwork frame or the formwork skin.
- the fastening element can also be designed as a recess or cavity in the sealing body, into which a projection of the formwork frame or the formwork skin is introduced for fastening.
- the fastening element can be formed by a fastening component, which can be a pin or a screw, for example. In this case, the fastening element can be positively connected to the sealing body at least in regions.
- the formwork frame has a bearing surface on which the formwork panel rests when the formwork element is in the assembled state.
- the bearing surface is preferably significantly smaller than the mold surface or a surface of the formwork facing opposite the mold surface.
- the bearing surface is preferably designed to be flat.
- the formwork frame has a frame edge which is arranged adjacent to the support surface and which runs in one direction protrudes perpendicularly to the bearing surface over the bearing surface.
- the frame edge is preferably arranged on the outer edge of the formwork frame in a plan view. In this view, the bearing surface is arranged within the edge of the frame.
- a surface arranged parallel to the support surface on the edge of the frame in the installed state terminates flush with the shaped surface of the formwork skin.
- the sealing profile is arranged between a surface of the frame edge facing in the direction of the formwork skin and the edge of the formwork skin.
- the surface of the frame edge pointing towards the formwork skin can be inclined relative to the support surface of the formwork frame, ie at an angle that differs from 90° and 0°.
- the peripheral edge of the formwork skin can be inclined, that is to say at an angle different from 90° and 0°, to the bearing surface.
- the sealing profile viewed in a cross section perpendicular to the direction of extension, can have a variable thickness in a direction perpendicular to the bearing surface.
- the aim of such an inclined arrangement of surfaces on the formwork frame, the formwork skin or the contact surfaces of the sealing profile is to provide centering for the assembly of the formwork skin in the formwork frame. Such centering helps during assembly, in which the formwork skin is introduced into the formwork frame in a direction perpendicular to the bearing surface, to set the correct relative position between the formwork skin and formwork frame in a plan view of the mold surface.
- the surface facing the formlining can be oriented at right angles to the support surface.
- a centering can be produced in that the sealing profile is thicker on its side facing in the direction of the bearing surface than on its side facing in the direction of the mold surface.
- Such a sealing profile can have a wedge-shaped cross section, for example.
- the circumferential edge of the formwork skin can be oriented in a correspondingly inclined manner to complement this shape.
- the angles of inclination of the wedge-shaped sealing profile and the inclined edge of the formwork skin are identical in this example and are, for example, 15°.
- the sealing profile is preferably elastically deformed, so that at least in certain areas there is a secure seal between the edge of the frame and the edge of the formlining. Centering can also be carried out in reverse, for example in that the surface of the frame edge facing the formwork skin is designed to be inclined and a wedge-shaped sealing profile is arranged on the edge of the formwork skin.
- the invention includes all possible combinations that ensure the described centering of the formlining to the formwork frame during assembly. Details of these possible combinations are presented in the embodiments described later.
- the sealing between the formwork frame and the formwork skin is significantly improved by a formwork element according to the invention.
- the sealing profile inserted between the edge of the frame and the edge of the formlining is dimensionally matched to the other components and is already in the fully formed state during assembly.
- the sealing profile is first connected either to the edge of the frame or to the edge of the formlining.
- the formlining is placed in the formwork frame with the help of the centering provided by the shape of the frame edge, sealing profile and edge of the formlining.
- the sealing profile is already correctly positioned between the two elements after the formlining has been placed on the support surface in the formwork frame and is immediately functional.
- the manual process of sealing between the formlining and the formwork frame by introducing liquid sealing material is therefore completely eliminated. This saves large quantities of sealing material, which, according to the prior art, have to be removed again after the sealing material has been introduced.
- the seal between the formwork frame and the formwork skin is of high quality, since the formwork frame, sealing profile and formwork skin were already matched during manufacture.
- the assembly time for a formwork element according to the invention is therefore significantly shorter than in the prior art and at the same time the seal between the formwork skin and the formwork frame is of significantly better quality.
- the sealing profile can be used several times, for example if the mold surface of the formwork skin has to be replaced due to wear and tear.
- the sealing between the formwork skin and the formwork frame in a formwork element according to the invention by means of the sealing profile arranged between them also enables tolerance compensation for manufacturing tolerances.
- the formwork frame and the formlining can Have side lengths of several meters, which are of course subject to tolerances in their manufacture. Dimensional inaccuracies in the range of several millimeters can be compensated without problems by the sealing profile in a formwork element according to the invention.
- the formwork element according to the invention thus provides improved long-term tightness between the formwork frame and the formwork skin both during assembly and in the assembled state during operation of the formwork element.
- additional functions can be integrated into the sealing profile, for example using sensors that measure temperature, pressure or the like.
- the thickness of the sealing profile in particular the distance between the contact surfaces in a direction perpendicular to the direction of extension and parallel to the bearing surface, varies in size starting from a plane defined by the mold surface in the direction of a plane defined by the bearing surface.
- the thickness of the sealing body varies between its contact surfaces in a direction perpendicular to the contact surface of the formwork frame or to the shaped surface of the formwork skin.
- Such a varying thickness can be used to provide centering when assembling the formlining into the formwork frame.
- Such a varying thickness can also be used to fix the sealing profile or the sealing body in a form-fitting manner between the formwork frame and the formwork skin.
- the thickness of the sealing body in the plane that is defined by the mold surface can be larger or smaller than in a plane that is defined by the bearing surface.
- the thickness of the sealing body can also vary between the planes defined by the bearing surface and the mold surface.

- the thickness of the sealing body in the application on the side of the Forming surface of the formlining may be larger or smaller than the thickness in the application on the side of the bearing surface.
- the thickness can change continuously or constantly. Alternatively, the thickness can change abruptly, for example due to a protruding area of the sealing body, which protrudes over another area with a sharp-edged transition.
- Such a varying thickness can be used to use the sealing profile to center the formlining during installation in the formwork frame or to secure the sealing profile between the formwork frame and formlining against unintentional release in the application.

- the angle between a first guide area of the first contact surface and a second guide area of the second contact surface is between 5° and is 20°.
- Such an angle in this area is particularly favorable in order to center the formwork skin during assembly in the formwork frame or to fix the sealing body in a form-fitting manner between the formwork skin and the formwork frame in the application.
- first sealing surface is adjacent to the first guide area and/or the second sealing surface is adjacent to the second guide area.
- Each contact surface includes a sealing surface and a guide area.
- the sealing surface and the guide area directly adjoin one another. If the guide areas are arranged at an angle to one another, the sealing surfaces can also be arranged at an angle to one another or else aligned parallel to one another. Alternatively, it is possible to arrange one or more transition areas between the sealing surface and the guide area.

- additional surfaces on the sealing body in the circumferential direction around the direction of extension, for example between the first end face and the first contact surface.
- This embodiment is particularly favorable in cooperation with an inclined edge of the formwork skin or an inclined surface of the frame edge pointing towards the formwork skin.
- the two sealing surfaces arranged parallel to one another provide a sealing area of the sealing body which has a constant thickness.
- the edge of the formlining is inclined in such a way that it is closer to the edge of the frame in a plane defined by the mold surface than in a plane formed by the bearing surface, a partial area of the sealing area is compressed more in the assembled state than another part. The greatest sealing effect occurs in this sub-area of stronger compression.
- the first sealing surface is also possible to arrange the first sealing surface at an angle to the second sealing surface which differs from 0° and 90°.
- the first end face is oriented essentially perpendicularly to the first sealing face and/or to the second sealing face.
- the first end face which usually comes into contact with the concrete material in the application, is oriented at right angles to one of the two sealing faces.

- the projection is preferably made of an elastic material, so that a partial area of the projection can be elastically deformed and, in this deformed state, can be introduced into a recess in the formwork frame or the formwork skin. Due to the elasticity, this partial area of the projection resumes its original shape after it has been introduced into the recess, as a result of which a form fit is produced between the recess or an area adjacent to the recess and the projection.
- the fastening element which is formed as a projection, to extend continuously along the direction of extension.
- the projection runs in the direction of extent without interruptions along the sealing body. This enables continuous attachment of the sealing profile to the formwork frame or to the soundboard.
- the fastening element formed as a projection has interruptions along the direction of extension and is arranged in particular in the direction of extension only in partial areas of the sealing profile.
- the fastening element formed as a projection is arranged along the direction of extent only in partial areas of the sealing body.

- This sensor is intended to determine measured values or parameters that occur in the application, when erecting a part of a building.
- a temperature sensor can be provided, which is arranged adjacent to the concrete material, which is filled into a formwork. The temperature determined by such a temperature sensor allows conclusions to be drawn about the curing state of the concrete material. The measured values of such a sensor can thus be used to determine whether the concrete material that has been poured in has already hardened sufficiently to remove the formwork element.
- Such a sensor can also be designed as a pressure or force sensor, which determines the pressure or force that a filled concrete material exerts on the formwork element.
- a sensor arranged in the sealing profile helps to monitor whether the formwork element is being loaded within the permissible operating range. The advantage of arranging a sensor on or in the sealing profile is that it is protected against environmental influences and against damage during attachment and transport of the formwork element.
- Such a sensor can easily be replaced together with the sealing profile or can also be retrofitted to existing formwork elements.
- This embodiment thus enables the formwork element to be expanded in a simple manner with additional functionalities.
- the assembly of a formlining in a formwork frame to form a formwork element is carried out by specialist personnel. This ensures that the installation of the sealing profile in the formwork element and thus the installation of the sensor is carried out by qualified personnel.
- a formwork element is provided on the construction site, which is already professionally installed.
- a sealing profile which extends along a direction of extent, comprising:
- the sealing body which at least partially consists of an elastic material, wherein the sealing body has at least two contact surfaces, wherein the contact surfaces are arranged on opposite sides of the sealing body and each run parallel to the direction of extension, and each of the contact surfaces is larger than the end faces of the sealing body arranged between the contact surfaces, the sealing body having at least two sealing surfaces, one of which forms a partial area of a contact surface,
- the sealing profile having at least one sensor which is designed as a temperature sensor, humidity sensor, pressure sensor, force sensor or strain sensor and which is on or in the sealing profile is arranged.
- a sealing profile is suitable for sealing a formwork skin to a formwork frame of a formwork element.
- such a sealing profile is also suitable for other applications in which two components are to be securely sealed relative to one another and in which measured values are also to be determined and evaluated using at least one sensor.
- the senor is at least partially surrounded by the sealing body.
- the sensor is arranged in regions within the sealing body.
- the sensor can also be completely enclosed by the sealing body, as a result of which the sensor is optimally protected against environmental influences.
- a temperature sensor can be integrated into the sealing body in this way.
- Other sensor types such as a pressure sensor or a humidity sensor, require direct contact with the concrete material. These types of sensors can be arranged in such a way that they lie on the surface of the sealing body in certain areas.
- the senor is arranged at least in regions in one of the end faces or one of the sealing faces and interrupts one of these faces.
- the sensor breaks through the end face or one of the sealing faces. In this way, the sensor comes into direct contact with the concrete material when used. As a result, a particularly precise acquisition of measured values and parameters is possible. It is also possible for several sensors to be provided, part of which is completely surrounded by the sealing body and another part which is arranged in such a way that it interrupts a surface of the sealing body.
- the senor is arranged on one of the end faces or one of the contact faces.
- the sensor is applied to a surface of the sealing body.
- the sensor can be glued to an end face or a contact surface on the outside. In this way, the attachment of the sensor to the sealing profile is possible in a simple manner.
- a face is a particularly favorable location, as this will normally come in direct contact with the concrete material in the application.
- sensors are arranged in or on the sealing body. These multiple sensors can be sensors of the same type or sensors of different types. The provision of several sensors of the same type enables a parameter to be measured at different points on the formwork element. It is also possible to provide several sensors of the same type redundantly, so that if one sensor fails, another sensor is available which determines the same measured values. By providing several sensors of different types, different parameters and measured values can be determined at the same time.
- the thickness of the sealing body, in particular between the contact surfaces, at a point where a sensor is arranged in the direction of extension is greater than the thickness of the sealing body at a point where no sensor is arranged in the direction of extension.
- the thickness of the sealing body varies in the direction of extension. At a point where a sensor is arranged in the sealing profile, this has a greater thickness than at other points.
- Some sensor types are larger than the usual distance between the formlining and the formwork frame of a formwork element. In order to enable the arrangement of such a type of sensor, the thickness of the sealing profile is increased locally. Correspondingly, corresponding areas must be provided on the formwork frame or on the formwork skin in order to enable this thicker area of the sealing profile to be accommodated.
- Such a type of sensor which has larger dimensions, can be a pressure sensor, for example.
- the senor has a sensor connection which is wired or wireless.
- the sensor requires a connection which is connected to a control unit or the like.
- the sensor connection can be wired, with a corresponding cable being able to extend within the sealing body.
- the sensor connection can also be designed wirelessly, for example as a radio sensor.
- the dimension by which the frame edge protrudes beyond the support surface is equal to or greater than the thickness of the formwork skin.
- the formlining is enclosed by the formwork frame.
- the formwork frame In the assembled state, the formwork frame preferably terminates flush with the shaped surface of the formwork skin in order to produce a part of the building that is as flat as possible. In some embodiments, however, the formwork skin tends to swell in the direction of thickness in the presence of moisture and thereby increase its thickness.
- the formwork element is preferably dimensioned such that the dimension by which the frame edge projects beyond the support surface is greater than the thickness of a non-swollen formwork skin.
- the formlining changes its thickness as a result of swelling, which results in relative movement to the formwork frame.
- the sealing profile is preferably designed in such a way that it does not move relative to the formwork frame when the formwork skin swells. The dimensional change caused by the swelling should only bring about a relative movement between the formlining and the sealing profile.
- the formwork skin is plate-shaped and has a force-transmitting surface opposite the mold surface, with the edge connecting the mold surface with the force-transmitting surface.
- the force transmission surface of the formlining rests on the support surface of the formwork frame and transfers the loads transmitted from the concrete material to the formlining to the formwork frame.
- the first sealing surface bears in a sealing manner on the frame edge and the second sealing surface bears in a sealing manner on the edge of the formwork skin.
- one sealing surface is in contact with the formlining and one with the formwork frame.
- the area between the sealing surfaces is preferably elastically deformed.
- One of the sealing surfaces preferably rests against a surface of the frame edge facing the formwork skin and another of the sealing surface rests against the edge of the formwork skin.
- the first end face is arranged between the mold surface and the frame edge in a plan view of the mold surface and/or the second end face rests on the support surface or an adjacent surface of the formwork frame.
- the first end face connects the shaped surface of the formwork skin with the edge of the frame.
- the second end face which is opposite the first end face, lies against the support surface of the formwork frame or against a surface arranged adjacent thereto.
- the sealing body is elastically deformed at least in regions between the formwork frame and the formwork skin.
- Such an elastic deformation arises from the fact that the sealing body is made thicker in the non-assembled state than the distance between the edge of the frame and the skin of the formwork. In this way, the sealing body is at least partially compressed during assembly and thus elastically deformed.
- This deformation creates a restoring force in the sealing body, which presses the sealing body and in particular its sealing surfaces against the formwork frame and the formwork skin. This ensures a good seal between the components.
- the size of the formwork skin changes parallel to the mold surface in the event of temperature fluctuations.
- the distance between the edge of the formlining and the edge of the frame varies.
- the sealing profile arranged in between compensates for this dimensional change in the formlining, which is caused by temperature fluctuations. If the temperature increases, the dimensions of the formlining increase and the sealing profile is additionally elastically deformed or compressed. If the size of the formlining is reduced due to a drop in temperature, the elastic deformation of the sealing body is also reduced.
- the elastic deformation of the sealing body is adjusted in such a way that at least a partial area of the sealing body is elastically deformed in every operating state, in particular at every ambient temperature, and a reliable seal is thus ensured.
- the fastening element is arranged on the first contact surface and is connected to the frame edge.
- the sealing profile is firmly connected to the frame edge of the formwork frame. This fixed connection is established before the formwork skin is mounted in the formwork frame. If the formlining is removed, the sealing profile remains connected to the edge of the frame.

In this way, the sealing body is enclosed in a form-fitting manner between the edge of the frame and the inclined edge of the formwork skin.

- the sealing profile 1 is connected to the formwork frame 101 via the fastening element 12 .
- the edge 1022 of the formwork skin 102 merely rests against the sealing profile 1 and is pressed against it.
- the fastening element 12 of the sealing profile 1 is positively connected to the frame edge 1012 .
- the sealing surface 101 is carried out by two sealing surfaces 113a and 113b on the sealing body 11, which each form partial areas of the contact surfaces 111a and 111b.
- the two sealing surfaces 113a and 113b are arranged parallel to one another.
- the first sealing surface 113a lies flat against the surface of the frame edge 1012 facing the formwork skin 102 .
- the second sealing surface 113b bears against the edge 1022 of the formwork skin 102 at least in certain areas.
- the two sealing surfaces 113a and 113b ensure a seal between the formwork skin 102 and the formwork frame 101 directly adjacent to the mold surface 1021.
- the first guide area 114a is arranged at an angle a to the second guide area 114b.
- the two guide areas 114a and 114b are planar.
- the partial area of the sealing body 11 which is located between the two guide areas 114a and 114b is wedge-shaped.
- this wedge-shaped partial area interacts with the inclined edge 1022 of the formwork skin 102.
- the angle a is preferably between 5° and 20°. In a simple embodiment, the angle a can be selected to be equal to the angle a′ which, when added to 90°, defines the inclination of the edge 1022 of the formwork skin 102 . In the assembled state, the entire second guide region 114b lies against the edge 1022 in this embodiment.
- a disadvantage of this embodiment can be that high frictional forces occur during assembly when the formwork skin 102 is being introduced into the formwork frame 101 due to the large contact surface. These frictional forces can lead to unwanted deformation or damage to the sealing profile 1 .
- the angle a' can be made larger than the angle a. This embodiment is shown in FIG. It can be seen that there is a small distance between the sealing body 11 and the edge 1022 in the vicinity of the bearing surface 1011 in particular.
- This wedge-shaped distance is caused by the angular difference between the angle a' and the angle a. This wedge-shaped distance reduces the contact surface between the edge 1022 and the guide area 114b. In this way, the formwork skin 102 can be mounted in the formwork frame 101 while overcoming lower frictional forces.
- the difference between the two angles a' and a is selected to be small and is preferably between 0.1° and 5°. As a result, the two angles a' and a in interaction still act as a centering when the formwork skin 102 is installed in the formwork frame 101.
- the sealing body 11 is wedge-shaped in some areas, with the wider side of the wedge at the bottom, adjacent to the bearing surface 1011 is arranged.
- the sealing body 11 thus widens downwards in the illustration, starting from the shaped surface 1021 .
- the sealing body 11 In addition to the effect described above for centering the formwork skin 102 during assembly in the formwork frame 101 causes such a wedge shape of a portion of the sealing body 11 that this form-fitting between the inclined edge 1022 of the formwork skin 102 and the Frame edge 1012 is included. This prevents the sealing profile 1 from being pulled out of its position between the formwork frame 101 and the formwork skin 102 in the application. In the application, it can happen that concrete material adheres to the first end face 112a. When separating the formwork element from the erected part of the building, a force acts on the sealing body 11, which is directed upwards from the mold surface 1021.
- the wedge shape of the sealing body 11 causes it to be positively retained in this direction, perpendicular to the mold surface 1021 . This ensures that the seal between the formwork skin 102 and the formwork frame 101 is permanently stable, even when in use.
- Such an effect of the positive fixing of the sealing body 11 between the formwork skin 102 and the formwork frame 101 is also given in the embodiments in FIGS. 6, 9, 16a and 17a.

- a first contact surface 111a is arranged on the left-hand side of the illustration, and a second contact surface 111b is arranged on the right-hand side.
- Both contact surfaces 111a and 111b extend in the vertical direction over the entire height of the sealing body 11.
- the two contact surfaces 111a and 111b together with the two end faces 112a and 112b, form the entire circumference around the sealing body in the sectional view shown.
- the two sealing surfaces 113a and 113b which run parallel to one another, are located adjacent to the first end face 112a.
- the first sealing surface 113a forms a portion of the first contact surface 111a and the second sealing surface 113b forms a portion of the second contact surface 111b.
- the area of the sealing body 11 below the sealing surfaces 113a and 113b is wedge-shaped.
- the area of the first contact surface 111a in which the sealing surface 113a is not arranged forms a first guide area 114a.
- the area of the second contact surface 111b in which the sealing surface 113b is not arranged forms a second guide area 114b.
- the two guide areas 114a and 114b are planar and oriented at an angle a to one another. The effect of the wedge shape in certain areas of the sealing body 11 is described in connection with FIG.
- the first sealing surface 113a is directly adjacent to the first guide area 114a and the second sealing surface 113b is directly adjacent to the second guide area 114b.
- Another partial area of the contact surface 111a, 111b is arranged between a sealing surface 113a, 113b and a guide area 114a, 114b, which separates the sealing surface 113a, 113b and the guide area 114a, 114b from one another.

- the first end face 112a is arranged at right angles to the two sealing faces 113a and 113b.
- This embodiment of a sealing body 11 is well suited, for example, for sealing a formwork element 100, as shown in FIG. In the installed state, the first end face 112a is in contact with the concrete material introduced into the formwork.
- the transition between the formwork frame 101 and the formwork skin 102 on the finished part of the building is smooth and thus ensures a visually pleasing appearance.
- the second end face 112b is arranged at an angle of less than 90° to the first contact surface 111a and at an angle of more than 90° to the second contact surface 111b. This results in the first contact surface 111a being longer in the vertical direction than the second contact surface 111b.
- This embodiment is particularly suitable for incorporation into a formwork frame 101 of the embodiment shown in FIG.
- the protruding tip at the point where the first contact surface 111a and the second end surface 112b meet can be introduced into the set-back transition area between the bearing surface 1011 and the surface of the frame edge 1012 oriented towards the formwork skin.
- the sealing body 11 is fixed in a form-fitting manner between the frame edge 1012 and the bearing surface 1011 of the formwork frame.
- the second end face can also be at a different angle, for example at right angles to the first Contact surface Illa be oriented.
- the thickness of the sealing profile 1 or of the sealing body 11 differs in the vertical direction in the illustration.
- This varying thickness in this direction which also corresponds to a direction that is directed perpendicularly to the bearing surface 1011 when the sealing profile 1 is installed, can center the formwork skin 102 during installation in the formwork frame 101 . It is not absolutely necessary for this that, as shown in FIG. 3, the sealing body 11 has a wedge-shaped design.
- a varying thickness in the vertical direction can also be produced by a curved design of one or both contact surfaces 111a and 111b.
- an abrupt increase in thickness in the vertical direction can also bring about a centering effect for the installation of the formwork skin 102 in the formwork frame 101 .

- the fastening element is formed by a projection which is arranged on the first contact surface 111a, in particular on the first guide region 114a, and protrudes beyond the first contact surface 111a.
- this projection 121 consists of the same elastic material as the sealing body 11 and together with this forms a common component.
- Two undercuts H are arranged adjacent to the projection 121, which are located between the projection 121 and the first attachment region 114a on which the projection 121 is arranged.
- the projection 121 has the shape of a dovetail.
- the two undercuts H are intended to be positively connected to a complementarily shaped area of the formwork frame, in particular the frame edge 1012 .
- Such a shape-complementary area on the frame edge 1012 can be formed, for example, by a slot which has the same width as the projection at its transition area to the first guide area 114a.
- the edge area of the slot is located in the two undercuts and the remaining projection, due to the elastic deformation back to its original state, creates a form fit with the slot and thus with the frame edge 1012 .
- the projection 121 extends in a constant form along the direction of extension ER into the plane of the drawing.
- FIG. 5 shows a third embodiment of a sealing profile 1 in a sectional view transverse to the direction of extension ER.
- the sealing body 11 is designed identically to the embodiment shown in FIG.
- the embodiment shown in FIG. 5 comprises a fastening element 12 designed as a projection 121.
- the projection 121 is arranged on the first guide region 114a and protrudes beyond the first contact surface IIIa.
- two undercuts H are arranged between the projection 121, or at least partial areas of the projection 121, and the first contact surface IIIa, which are provided for the positive connection with the formwork frame 101.
- the two undercuts H have a rectangular cross section in the sectional view shown.
- the projection 121 has interruptions along the extension direction ER and is only arranged in partial areas in this direction on the sealing body 11 .
- a plurality of projections 121 are thus attached to the sealing body 11 along the direction of extension ER.
- these projections 121 can have a circular shape, for example.
- correspondingly circular openings can be provided on the frame edge 1012, into which the projections 121 are pressed when the sealing profile 1 is installed. Such an embodiment is shown in FIG.
- the projections 121 made of an elastic material are pressed through a circular opening in the surface of the frame edge 1012 facing the formwork skin 102 .
- the undercuts H encompass the edge of the circular openings, the part of the projection 121 facing to the left in Fig. 5 rests on the side of a partial area of the frame edge 1012 facing away from the sealing body and thus fixes the sealing profile 101 in a form-fitting manner on the shuttering frame 101. It is also possible to arrange the embodiment of a projection 121 shown in FIG. 5 constantly endang the extension direction ER.
- FIGS. 6 to 9 Further embodiments of a formwork element 100 are shown in FIGS. 6 to 9 .

- the sealing body 11 is shaped in such a way that its thickness, in particular the distance between its two contact surfaces 111a and 111b, increases from top to bottom in a direction perpendicular to the contact surface 1011 in the illustration.
- the slope of the edge 1022 of the formwork skin 102 is designed to be complementary in shape to the wedge shape of the sealing body 11 . Due to the fact that the thickness of the sealing body 11 adjacent to the bearing surface 1011 is greater than the thickness of the sealing body 11 adjacent to the shaped surface 1021, the sealing profile 1 becomes form-fitting due to the inclination of the edge 1022 in a direction perpendicular to the bearing surface 1011 between the formlining 102 and the formwork frame 101 fixed. In the illustrated embodiment, the inclined edge 1022 and the sealing profile 1 are firmly connected to one another before the formwork skin 102 is installed in the formwork frame 101 .
- the inclined edge 1022 in combination with the wedge shape of the sealing profile 1, does not create any centering during the assembly of the formwork skin 102 in the formwork frame 101.
- a centering effect during assembly is achieved in that the sealing body 11 is on its side facing away from the mold surface 1021 at the beginning is elastically deformed during assembly, with this deformation also temporarily resulting in a wedge shape and thus a centering effect.
- the state shown in FIG. 6 sets in, in which this lower region of the sealing body 11 has elastically deformed back and is fixed between the frame edge 1012 and the formwork skin 102 .
- Fig. 7 shows a sectional front view of a portion of another embodiment of a formwork element 100 according to the invention.
- the surface of the frame edge 1012 facing the formwork skin 102 is at an angle other than 90° to the bearing surface 1011 and is therefore inclined.

- centering is achieved during the assembly of the formwork skin 102 in the formwork frame 101 in that the first contact surface IIIa, which is designed inclined to the support surface 1011, slides along the likewise inclined surface of the frame edge 1012 facing the formwork skin 102, whereby the formlining 102 is centered on the frame edge 1012 during assembly.

- Fig. 8 shows a sectional front view of a portion of a further embodiment of a formwork element 100 according to the invention.
- both the surface of the frame edge 1012 facing the formwork skin 102 and the edge 1022 of the formwork skin 102 are in one of 90 ° different angles to the bearing surface 1011 and thus run inclined.
- the sealing body 11 has an essentially constant thickness between its two contact surfaces 111a and 111b.
- the sealing profile 1 is positively and securely connected to the edge 1022 by a fastening element designed as a projection 121 .
- the left-facing first contact surface IIIa of the sealing body 11 and the surface of the frame edge 1012 facing the formwork skin 102 interact and, due to their inclined arrangement, center the formwork skin 102 to the formwork frame 101.
- the two guide areas 114a and 114b of the sealing body 11 are oriented parallel to one another.
- FIG. 9 shows a sectional front view of a partial area of a further embodiment of a formwork element 100 according to the invention.
- This surface of the frame edge 1012 facing the formwork skin 102 is arranged in the embodiment in FIG. 9 in such a way that an undercut occurs in a direction perpendicular to the bearing surface 1011 in the lower region of this surface.

- the edge 1022 of the formwork skin 102 is oriented at right angles to the bearing surface 1011 in the embodiment shown in FIG.
- the sealing profile 1 is firmly connected to the formwork skin 102 by a fastening element 12 designed as an adhesive surface.
- the sealing body 11 is wedge-shaped in some areas, the thickness between its two contact surfaces 111a and 111b being greater on its side facing the contact surface 1011 than on its side Form surface 1021 side facing. Due to this shape, the sealing profile 1 is enclosed in a form-fitting manner between the inclined edge of the formwork frame 1012 and the formwork skin 102 in the assembled state shown. This effectively prevents the sealing profile 1 from being pulled out in a direction perpendicular to the bearing surface 1011 between the frame edge 1012 and the formwork skin 102 in the application.
- the inclined arrangement of the surface of the frame edge 1012 facing the formwork skin 102 in conjunction with the wedge shape of a portion of the sealing profile 1 does not cause any centering when the formwork skin 102 is installed in the formwork frame.

- the cavity 115 is arranged between the two guide areas 114a and 114b.
- the cavity 115 is not located between the two visible surfaces 113a and 113b.
- the wall thickness of the sealing body 11 around the cavity 115 is essentially constant at the guide regions 114a and 114b and at the second end face 112b. In the application is in the cavity 115 air.
- the sealing body 11 shown with a cavity 115 has a lower spring stiffness in a direction perpendicular to the sealing surfaces 113a and 113b.
- the sealing body 11 in the embodiment shown in FIG. 13 offered less resistance to the formwork skin 102 during the assembly of the formwork skin 102 in the formwork frame 101, as a result of which the latter can be fitted with less effort.
- the cavity 115 saves material compared to a solid sealing body 11.
- the elastic properties of the sealing body 11 can be adjusted by varying the position and the size of the cavity 115 .
- a connection opening 1151 can be seen in the illustration, which connects the cavity 115 to the outside of the sealing body 11 through the second guide region 114b. Through this connection opening, in the event of compression or elastic deformation of the sealing body
- the sealing profile 1 has an adhesive surface arranged on the first guide area as the fastening element 12 .
- a cavity 115 can also be combined with other embodiments of a sealing profile 1 .
- FIG. 14 shows an eighth embodiment of a sealing profile 1 in a sectional view transverse to the direction of extent ER.
- the outer shape of the sealing body 11 of the embodiment of a sealing profile 1 shown in FIG. 14 is based on the embodiment described in FIG.
- two recesses 116 are arranged in the first contact surface 111a, in the first guide region 114a. These two recesses 116 interrupt the first bearing surface Illa.
- the thickness of the sealing body 11 is reduced in some areas by the recesses 116 . This results in changed elastic properties of the sealing body 11.
- the rigidity of the sealing body 111 is reduced by the recesses 116 compared to an embodiment in which the sealing body is solid, as shown for example in FIG.
- the sealing body 11 opposes less resistance to the formwork skin 102 during the assembly of the formwork skin 102 in the formwork frame 101, as a result of which the latter can be fitted with less effort.
- two adhesive surfaces, which form the fastening element 12 are arranged on the areas of the first guide area 114a which are arranged adjacent to the recesses 116 .
- the recesses 116 are arranged in a region of the first contact surface 111a which lies outside of the first sealing surface 113a. In this way, the recesses 116 do not affect the sealing effect of the sealing surfaces 113a and 113b.

- the recesses 116 reduce the area of the second guide region 114b on which the edge 1022 of the formwork skin 102 comes into contact when the formwork skin 102 slides along in the formwork frame 101. This reduction in the surface area of the second guide area 114b reduces the friction when the formwork skin 102 is installed. Due to this reduced friction, the formwork skin 102 can be mounted in the formwork frame 101 with reduced force. As in the embodiment shown in FIG. 14, the recesses 116 are arranged outside the area of the two sealing surfaces 113a and 113b and therefore do not affect their sealing effect when the formwork element 100 is in the assembled state.

- Control unit S is to be understood as meaning a device that records and stores the data determined by sensors 13 and preferably also evaluates or processes them further.
- the arrangement or accommodation of sensors 13 in the sealing profile 1 has the advantage that they are arranged in the immediate vicinity of the concrete material of the part of the building to be erected.
- sensors 13 can be arranged in a protected manner inside or at least partially surrounded by the sealing body 11 .
- Sensors 13 arranged in sealing profile 1 can easily be retrofitted in existing formwork elements 100 by simply using a corresponding sealing profile 1 for sealing between the formwork skin 102 and the formwork frame 101 .
- FIG. 17a shows a sectional front view of a partial area of a further embodiment of a formwork element 100 according to the invention with a sealing profile 1 with sensors 13.
- the embodiment shown in FIG. 17a is based on the embodiment shown in FIG.
- the sealing profile 1 has a plurality of sensors 13 in the embodiment shown in FIG. 17a.
- the sectional plane in FIG. 17a corresponds to the sectional plane II drawn in FIG. 1.
- the sealing profile 1 is cut in such a way that the sectional plane is not in an area in which a sensor 13 is arranged.
- a sensor 13 is arranged behind the cutting plane, which is arranged adjacent to or adjacent to the first end face 112a.
- the thickness of the sealing body 11 between its contact surfaces 111a and 111b, in a direction parallel to the contact surface 1011, is greater at the point at which a sensor 13 is arranged in the direction of extension ER than its thickness at a point where no sensor 13 is arranged. Such a point at which a sensor 13 is arranged is behind the section plane. There the thickness of the sealing body 1 is greater than in the sectional plane. At this point, the sealing body 11 extends further into the frame edge 1012 than in the sectional plane. To accommodate this thicker point of the sealing body 11, a recess A is provided in the frame edge 1012 in the illustrated embodiment, which recess extends into the end face 1012a. The recess A can be seen clearly in the plan view in FIG. 17b.
- FIGS. 17a, 17b, 18a and 18b make it possible to arrange sensors 13 in a formwork element 100, in its sealing profile 1, which have larger dimensions than the distance between the formwork skin 102 and the formwork frame 101.
- Pressure sensors in particular often have a Measuring surface, which is larger than the usual distance between formwork skin 102 and formwork frame 101.
- the recesses A in the formwork frame 101 make it possible to arrange such sensors 13 in thicker places in the sealing body 11 .
- these recesses A can be used in conjunction with the thicker points on the sealing body 11 at the same time for fixing the sealing profile 1 to the formwork frame 101 .
- a thicker area of the sealing body 11, in which a sensor 13 is arranged can also function as a fastening element 12.
- a differently designed fastening element 12 for example an adhesive surface or a projection 121 to provide.
- FIG. 17b shows a top view of a partial area of the embodiment of a formwork element 100 shown in FIG. 17a.
- FIG. 17b shows a top view of the embodiment shown in FIG. 17a.
- a plurality of recesses A are arranged in the frame edge 1012 at a distance from one another in the direction of extent ER. These recesses extend from the surface of the frame edge 1012 facing the formwork skin 102 into the end surface 1012a.
- the recesses A have the shape of a semicircle in the top view shown. Of course, the recesses A can also have a different shape.
- the sealing profile 1, in particular its sealing body 11, is thicker and complementary in shape to the recesses A at points spaced apart from one another endang the direction of extension ER. Sensors 13 can be arranged at each of these points. However, it is not absolutely necessary for a sensor 13 to actually be installed at each of these thicker points or in each recess A on the shuttering frame 101 .
- Fig. 17b only a portion of the formwork element 100 is shown in plan view.
- a sealing profile 1 in the illustrated embodiment in interaction with recesses in the frame edge 1012 can be arranged around the entire formwork element 100 . Alternatively, it is possible to arrange the embodiment shown only in a partial area of the circumference, for example only on one side of the formwork element 100 .
- FIG. 18a shows a sectional front view of a portion of a further embodiment of a formwork element according to the invention with a sealing profile 1 with sensors 13.
- the embodiment shown in FIG. 18a is similar to the embodiment shown in FIG. 17a. Unless otherwise described, reference is therefore made to the description of FIG. 17a.
- the sealing body 11 in the embodiment shown in FIG. 18a has at least one sensor 13, the thickness of the sealing body 11 being greater at the point where the sensor 13 is arranged than at points in the direction of extent ER where no sensor 13 is arranged is. In contrast to the embodiment shown in FIG. 17a, however, the greater thickness of the sealing body 11 in the area of the sensor 13 does not extend into the edge of the frame 1012 into it, but into the mold surface 1021 of the formwork skin 102.
- the formwork skin 102 has a recess A in the illustrated embodiment.
- This recess A extends into the mold surface 1021 and is designed to complement the shape of the point on the sealing body 11 at which the sensor 1 is arranged.
- the interaction of the recess A with the sealing profile 1 can be seen in the plan view in FIG. 18b.
- a control device S is arranged on the side of the shown partial area of the formwork frame 101 which faces to the right in the illustration. This control device S communicates wirelessly with one or more sensors 13 which are arranged in the sealing body 11 .
- the control unit S is arranged in a protected manner below the formwork skin 102 and is located in the vicinity of the sensor 13.
- control device S is protected against environmental influences and damage during use due to its arrangement within the formwork frame 101 and below the formwork skin 192 .
- the control device S can in turn communicate wirelessly with other control devices S or a server and transmit the measured values determined by the sensor 13 for evaluation.
- FIG. 18b shows a top view of a partial area of the embodiment of a formwork element 100 shown in FIG. 18a.
- the edge area of the formwork skin 102 can be used for arranging sensors 13 which are integrated into the sealing profile 1 .
- the form fit between the sealing profile 1 in the area of the sensors 13 and the recesses A can be used at the same time to fasten the sealing profile 1 to the formwork skin 102 . It is also possible to combine the embodiment shown in FIG. 18b with the embodiment shown in FIG Record 100 portions of the sealing body 11 in which sensors 13 are arranged.
