    The invention relates to a formwork system for producing a formwork for a precast concrete element, comprising shuttering profiles, each having two longitudinal sides and two intermediate end faces, wherein the shuttering profiles are subdivided into a first group and a second group, the shuttering profiles of the second group are provided be arranged substantially perpendicular to one or more formwork profiles of the first group, and at least the formwork profiles of the first group on at least one longitudinal side have a projecting inclined surface for forming a chamfer in a precast concrete part. The invention further relates to a formwork from formwork profiles of the formwork system according to the invention on a substrate.
    Formwork systems according to the preamble of claim 1 are known from EP 2 017 047 B1. The shuttering profiles of the first group are also referred to as a transverse stop and the shuttering profiles of the second group as a longitudinal stop. The formwork profiles of such a formwork system according to the prior art each have at both end faces - viewed from a direction perpendicular to one of the longitudinal sides - a recess for receiving the inclined surface of a formwork profile from the first group. If you now line several formwork profiles of the second group, so the Längsabsteller, one behind the other, to achieve a certain overall length, resulting in the places where the end faces abut, gaps in the concrete can swell. This leaves impressions in the precast concrete element that disturb the overall aesthetic impression. In the case of triangular recesses, there are gaps which are indicated by dot-dash lines 49 in FIG.
    One approach is to manually fill the gaps with a filler, e.g. Styrofoam, to close. This is a bonding step connected. When removing the formwork profiles after the concrete has hardened, the filler must be removed from the formwork profiles. With these steps, therefore, a considerable effort is connected, especially in a formwork a number of such gaps must be closed.
    The objective technical task is now to provide a formwork system in which the described disadvantages of the prior art are avoided, and with which it is particularly possible to produce a complete formwork.
    This object is solved by the features of independent claim 1.
    It is thus provided according to the invention that the second group of shuttering profiles can be subdivided into a first subgroup, a second subgroup and a third subgroup, wherein the shuttering profiles of the first subgroup at exactly one first end face - viewed from a direction perpendicular to one of the longitudinal sides - a Recess for receiving the inclined surface of a formwork profile from the first group, the formwork profiles of the second subgroup at exactly one, the first end opposite the second end face - viewed from a direction perpendicular to one of the longitudinal sides - a recess for receiving the inclined surface of a formwork profile of the first Group have, and the formwork profiles of the third subgroup on either end face - viewed from a direction perpendicular to one of the longitudinal sides - a recess for receiving the inclined surface of a formwork profile from the first group.
    Combining a formwork profile from the first subgroup with a second formwork profile from the second subgroup and optionally one or more intermediate formwork profiles from the third subgroup, and aligns the formwork profile of the first subgroup and the formwork profile of the second subgroup such that that end face, which has the recess for receiving the inclined surface of a formwork profile from the first group to the outside, ie in the direction of (an inclined surface having) longitudinal side of Querversesteller points, so the interfaces between the shuttering profiles are gapless (see Figure 1).
    According to a preferred embodiment of the invention, it is provided that the formwork profiles of the second group have on a longitudinal side, preferably on exactly one longitudinal side, a protruding oblique surface for forming a chamfer in a precast concrete part. In the event that on precisely one longitudinal side a protruding inclined surface is provided for forming a chamfer in a precast concrete part, the shuttering profiles can either be used to produce precast concrete without chamfer or produce precast concrete with a chamfer. You only need to rotate it by 180 °. In addition, the formwork profiles of the first and the second subgroup in this case can be well distinguished from each other, since they have only one of the longitudinal sides of a projecting inclined surface and are thus not symmetrical, so that the two end faces by their arrangement with respect to the inclined surface distinguished longitudinal side.
    It has proven to be particularly favorable if the first subgroup comprises shuttering profiles with lengths of 49, 50, 51, 52, 53, 54 and 55 cm and / or the second subgroup of shuttering profiles with lengths of 49, 56, 63, 70, 77 , 84 and 91 cm and / or the third subgroup includes formwork profiles with lengths of 49, 98, 147, 196 and 294 cm. This is particularly advantageous since relatively few shuttering profiles of different lengths are required in this way in order to realize all overall lengths of centimeters from 98 cm (see FIG. 8).
    Further advantageous embodiments of the invention are defined in the dependent claims 6 to 11.
    Protection is also desired for a shuttering formwork profiles of the formwork system according to the invention on a substrate.
    Advantageously, the formwork here consists at least of a formwork profile of the first subgroup, optionally one or more shuttering profiles arranged therebetween from the third subgroup and a shuttering profile from the second subgroup, wherein the shuttering profiles are oriented relative to each other such that the two longitudinal sides respectively substantially lie the same level and that end face of the formwork profile from the first subgroup and that end face of the formwork profile from the second subgroup, which has the recess, is directed in each case to the outside.
    In addition, it can be provided that in each case a formwork profile from the first group is arranged with a longitudinal side of the outwardly directed end side of the formwork profile facing out of the first and the second subgroup.
    Such formworks are substantially completely formed.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the drawings. Showing:

    Subgroup of the formwork system illustrated in FIG. 2, FIGS. 6 a) to 6 c) show three views of a formwork profile from the first group of the formwork system illustrated in FIG. 2,
    Fig. 7a) and 7b) is a cross-sectional view of a formwork profile for illustrating the operation of the means for releasably fixing a shuttering profile on a substrate, wherein the partial figures a) and b) show two different positions of this agent, and
    Fig. 8 is a schematic diagram for illustrating the
    Possible combinations of the formwork profiles of the formwork system shown in Figure 2.
    1 shows a perspective view of a formwork 61 of two formwork profiles 25 from the first group 2 (see Figure 2) and three arranged therebetween shuttering profiles 7, 65 and 14 from the second group 3, wherein the shuttering profile 7 of the first subgroup 4, the Formwork profile 65 of the third subgroup 6 and the formwork profile 14 of the second subgroup 5 stems. The formwork 61 is arranged on a base 39. The shuttering profiles 7, 65 and 14 are arranged relative to each other so that each of their longitudinal sides 27 and 28 (see, for example, Figure 3) lie substantially in the same plane and that end face 32 of the shuttering profile 7 from the first subgroup and that end face 31 of the shuttering profile 14th from the second subgroup, which has the recess 36 (shown in dashed lines), each directed to the outside, ie the longitudinal side 29 and 30 of the shuttering profiles 25 faces. In the recesses 36 projecting from the longitudinal sides 29 and 30 of the formwork profiles 25 inclined surfaces 35 are arranged. Overall, this results in a gapless formwork 61. In comparison, were in the prior art at the interfaces between the shuttering profiles 7 and 65 and 65 and 14 gaps before, which are shown in dotted lines.
    The inclined surfaces 35 are at an angle 37 of about 45 ° from the longitudinal sides 29, 30 and have in a cross section parallel to a front side a length 38 of about 15 mm. A corresponding inclined surface 35 also have the shuttering profiles 7, 65 and 14 on the longitudinal side 27.
    All formwork profiles are formed in a cross section parallel to a front side substantially U-shaped.
    They furthermore each have a lower side 39 facing the lower side and a spaced-apart upper side 43 and 42, respectively. It can be seen that the inclined surfaces 35 and the recess 36 are formed for receiving one of the inclined surfaces on the respective underside of the formwork profiles adjacent to the longitudinal side or on the end side.
    2 shows a schematic representation of an inventive formwork system 1 according to a preferred embodiment: The formwork system is subdivided into a first group 2 of formwork profiles 25, 26 and into a second group 3 of formwork profiles 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 and 65 wherein the formwork profiles of the second group are intended to be arranged substantially perpendicular to one or more formwork profiles of the first group. The shuttering profiles of the first group are also referred to as a transverse stop and the shuttering profiles of the second group as a longitudinal stop. The formwork profiles of the first group 2 each have at exactly one or both sides a protruding inclined surface to form a chamfer in a precast concrete part to be produced. The formwork profiles of the second group 3 have on exactly one longitudinal side on a projecting inclined surface to form a chamfer in a manufactured precast concrete.
    If the shuttering profiles have a projecting inclined surface only on exactly one longitudinal side, then they can either be used to produce precast concrete parts without chamfer or to produce precast concrete parts with a chamfer. You only need to rotate it by 180 °.
    The second group 3 of the formwork profiles is subdivided into a first subgroup 4, a second subgroup 5 and a third subgroup 6, the formwork profiles 7, 8, 9, 10, 11, 12, 13 of the first subgroup 4 at exactly one, first end side a recess for receiving the inclined surface of a formwork profile from the first group, the formwork sections 14,15,16, 17,18,19, 20 of the second subgroup 5 at exactly one, the first of the end opposite the second end face a recess for receiving the inclined surface a shuttering profile from the first group and the shuttering profiles 21,22, 23, 24, 65 of the third subgroup 6 have at each of the two end faces a recess for receiving the inclined surface of a shuttering profile from the first group.
    The formwork profiles of the first and the second subgroup can therefore be distinguished from each other, since they have only one of the longitudinal sides of a projecting inclined surface and are thus not symmetrical, so that the two end faces are characterized by their arrangement with respect to the oblique surface having longitudinal side ,
    The provided with the reference numeral 7 formwork profile of the first subgroup 4 has a length of 49 cm. The shuttering profiles designated by the reference symbols 8, 9, 10, 11, 12 and 13 accordingly have a length of 50, 51, 52, 53, 54 and 55 cm. The formwork profiles of the second subgroup 5 designated by the reference numerals 14, 15, 16, 17, 18, 19 and 20 have a length of 49, 56, 63, 70, 77, 84 and 91 cm. The formwork profiles of the third subgroup 6 designated by the reference numerals 21, 22, 23, 24 and 65 have a length of 98, 147, 196, 294 and 49 cm.
    As can be seen from FIG. 8, with this set of formwork profiles from the second group centimeter-accurate, all lengths from 98 cm can be realized, wherein in FIG. 8 the total lengths 60 between 103 and 247 cm are shown. In each case only one formwork profile from the first subgroup 4 with a formwork profile from the second subgroup 5 and, if appropriate, one or more formwork profiles from the third subgroup 6 must be combined therebetween.
    The subfigures a) to e) of FIG. 3 show a formwork profile 7, 8, 9, 10, 11, 12 or 13 from the first subgroup 4 of the second group 3 of formwork profiles (see FIG. 2). The formwork profiles of this subgroup differ essentially only in their length 51 from each other, wherein the realization of different lengths 51 of the sub-figure b) drawn distance 54 between the two means 44 for releasably fixing the formwork profiles on a substrate is chosen to vary in size.
    The partial figure a) of Figure 3 shows a perspective view, the partial figure b) is a cross-sectional view in the longitudinal direction and the sub-figure c) is a cross-sectional view along the cut plane 62 shown in dashed lines in Figure b) parallel to one of the end faces 31 and 32nd Teilteil d ) shows a plan view from above and part figure e) an enlarged section of the end portion of the formwork profile, which is marked in dashed lines in the subfigure d).
    A formwork profile from this subgroup - and the other subgroups - is formed in cross section parallel to one of the end sides substantially U-shaped and has a bottom 40 and a top 42, two end faces 31 and 32 and two intermediate longitudinal sides 27 and 28, wherein on one of the longitudinal sides of a projecting inclined surface 35 and on the end face 32, viewed from a direction perpendicular to one of the longitudinal sides, a recess 36 for receiving an inclined surface of a formwork profile from the first group is provided.
    In addition, two means 44 for fixing the shuttering profiles are provided on a ferromagnetic base, wherein the means comprise an in use position of the shuttering profiles accessible from its top 42 actuator 45 and magnetic means 46 which can be arranged in a first and in a second operating position, wherein the Magnetic means in the first operating position, a first distance 47 to the ground (see Figure 7b)) and in a second operating position, a second distance 48 to the ground (see Figure 7a)) not equal to the first distance, and wherein the second distance 48 is equal to zero. For moving the magnetic means 46 from the first to the second operating position or vice versa, the actuating element 45 is provided.
    The actuator 45 also offers an opportunity to attack the formwork profiles automatically remove a magazine and to be able to position on the ground. For mounting in the magazine, the formwork profiles on their upper side 42 at each of their ends U-shaped cuts 50.
    It should be pointed out that the shuttering profiles 25, 7, 65 and 14 shown in FIG. 1 are simplified in that the magazine holders 50 and the means 44 for the releasable fixing of the shuttering profiles on a substrate have been omitted. It should also be pointed out that the means for releasably fixing illustrated in the following FIGS. 4 to 6 are identical to the means for releasably fixing provided in the formwork profiles according to FIG.
    FIGS. 4a) to d) show a formwork profile 14, 15, 16, 17, 18, 19 and 20 from the second subgroup 5 of the second group 3 (see FIG. 2), the formwork profiles of this subgroup essentially being characterized differ from each other in that they have a different length 52. The different lengths are realized in that the distance 55 between the means 44 for releasably fixing is chosen to be different. The subfigure a) again shows a perspective view, the subfigure b) a cross-sectional view in the longitudinal direction, the subfigure c) a cross-sectional view along the sectional plane 63 shown dashed in the subfigure b) and the subfigure d) a top view from above.
    The essential difference between the formwork profiles from the first subgroup (see FIG. 3) and the formwork profiles from the second subgroup according to FIG. 4 is that the recess 36 for receiving an inclined surface of a formwork profile from the first group is not on the end face 32, but instead is formed on the opposite end face 31.
    To the recess 36 is generally noted that, since the formwork profiles are U-shaped in cross-section, the recess is that the corners facing the ground of the "U's" are chamfered at the end face 31 and at the same angle with respect on the front side 31, under which the inclined surfaces protrude from the longitudinal sides. The length of the running between the front side and the underside of the formwork profiles inclined surface is slightly larger than the length of the inclined surface in a cross section parallel to the front side, so that a total - in its geometry - corresponding to the inclined surface recess results. The recess and the inclined surfaces are identical in all formwork profiles. In FIG. 6b), the angle of the oblique surface delimiting the recess is designated by reference numeral 59 and its length by reference numeral 58.
    Figures 5a) and b) show shuttering profiles 21,22, 23, 24 and 65 of the third subgroup 6 (see Figure 2), which in contrast to the formwork profiles of the subgroups 1 and 2 at their end faces 31 and 32 have no recesses. Otherwise, the formwork profiles of this subgroup are similar to the formwork profiles of the other subgroups. Since it is formwork profiles with a comparatively long lengths 53, wherein different lengths by variations of the sub-figure a) drawn
    Distance 56 come about, triangular braces 64 are still considered in this formwork profiles when viewed in cross section.
    Figures 6a) to c) show a formwork profiles 26 from the first group 2 (see Figure 2) with a total length 57 of 300 cm. In contrast to the formwork profiles 25 shown in FIG. 1, in this case the formwork profile 26 has a protruding oblique surface 35 only on the longitudinal side 29. At the same time 33 and 34 recesses 36 are provided on both end faces. Due to its length, the formwork profile shown has three means 44 for releasably fixing the formwork profile on a substrate and a plurality of struts 64. Part of Figure 6b) shows an enlarged section of one of the ends of the formwork profile, wherein the section shown in the partial figure a) is shown in dashed lines. Based on this section, the shape of the recess 36, which are identical in the formwork profiles of the second group, which have a recess formed, understand. The underside of the shuttering profile facing a background is designated by the reference numeral 41 and the upper side by the reference numeral 43.
