Definitions

  • the invention relates to a formwork system for producing a formwork for a precast concrete part, comprising formwork profiles each having two longitudinal sides and two end faces in between, the formwork profiles being divisible into a first group and a second group, the formwork profiles of the second group being provided for this purpose to be arranged essentially perpendicular to one or more shuttering profiles of the first group, and at least the shuttering profiles of the first group have a protruding inclined surface on at least one longitudinal side for forming a bevel in a precast concrete part.
  • the invention further relates to a formwork made of formwork profiles of the formwork system according to the invention on a substrate.
  • Formwork systems according to the preamble of claim 1 are from EP 2 017 047 B1 known.
  • the formwork profiles of the first group are also referred to as transverse abutments and the formwork profiles of the second group as longitudinal abutments.
  • the formwork profiles of such a formwork system according to the prior art each have on 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.
  • several formwork profiles of the second group i.e. the lengthways shelves, are lined up one behind the other in order to achieve a certain total length, there are gaps at the points where the end faces meet, into which concrete can swell. This leaves imprints in the precast concrete part that disrupt the overall aesthetic impression.
  • there are gaps in the Figure 1 are indicated by dash-dotted lines 49.
  • One approach is to manually close the gaps with a filler material such as styrofoam. This involves an adhesive step. When removing the shuttering profiles after the concrete has hardened, the filler must be removed from the shuttering profiles again. These steps are therefore associated with considerable effort, especially since a number of such gaps must be closed in a formwork.
  • the EP 2 255 938 A2 discloses such special formwork elements made of Styrofoam, which are cut individually depending on the formwork in order to fill gaps. These special formwork elements are one-way formwork elements.
  • the objective technical task now consists in specifying a formwork system in which the described disadvantages of the prior art are avoided and with which it is in particular possible to produce a complete formwork.
  • the second group of formwork profiles can be subdivided into a first subgroup, a second subgroup and a third subgroup, with the formwork profiles of the first subgroup on exactly one first end face - viewed from a direction perpendicular to one of the longitudinal sides Have a recess for receiving the inclined surface of a formwork profile from the first group, the formwork profiles of the second subgroup on exactly one second end face opposite the 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 Have group, and the formwork profiles of the third subgroup on none of the two end faces - viewed from a direction perpendicular to one of the longitudinal sides - have a recess for receiving the inclined surface of a formwork profile from the first group.
  • the formwork system of the present invention is reusable and consists of formwork profiles of fixed lengths. This means that the formwork profiles do not always have to be made individually for a specific formwork, but that any formwork can be built from the system of formwork profiles, in particular with centimeter precision.
  • the formwork profiles of the second group have a protruding inclined surface on one longitudinal side, preferably on exactly one longitudinal side, for forming a bevel in a precast concrete part.
  • the formwork profiles can either be used to produce precast concrete parts without a bevel or to produce precast concrete parts with a bevel. They only have to be rotated by 180 °.
  • the formwork profiles of the first and second subgroups can be easily distinguished from one another in this case, since they only have a protruding inclined surface on one of the long sides and are therefore not symmetrical, so that the two end faces are different due to their arrangement in relation to the inclined surface mark out the long side.
  • the first subgroup comprises formwork profiles with lengths of 49, 50, 51, 52, 53, 54 and 55 cm and / or the second subgroup comprises formwork 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.
  • Protection is also sought after for a formwork made of formwork profiles of the formwork system according to the invention on a substrate.
  • the formwork consists of at least one formwork profile from the first subgroup, optionally one or more formwork profiles arranged in between from the third subgroup and one formwork profile from the second subgroup, the formwork profiles being oriented relative to one another in such a way that the two longitudinal sides are each essentially in lie on the same plane 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, are each directed outwards.
  • a formwork profile from the first group is arranged with a longitudinal side facing the outwardly directed end face of the formwork profile from the first or the second subgroup.
  • Figure 1 shows in a perspective view a formwork 61 made of two formwork profiles 25 from the first group 2 (cf. Figure 2 ) and three formwork profiles 7, 65 and 14 arranged in between from the second group 3, the formwork profile 7 from the first subgroup 4, the formwork profile 65 from the third subgroup 6 and the formwork profile 14 from the second subgroup 5.
  • the formwork 61 is arranged on a substrate 39.
  • the formwork profiles 7, 65 and 14 are arranged relative to one another in such a way that their longitudinal sides 27 and 28 (compare e.g.
  • Figure 3 lie essentially in the same plane and that end face 32 of the formwork profile 7 from the first subgroup and that end face 31 of the formwork profile 14 from the second subgroup, which has the recess 36 (shown in dashed lines), each facing outwards, ie the longitudinal side 29 or 30 facing the formwork profiles 25.
  • the inclined surfaces 35 protruding from the longitudinal sides 29 and 30 of the formwork profiles 25 are arranged in the recesses 36.
  • the inclined surfaces 35 protrude from the longitudinal sides 29, 30 at an angle 37 of approximately 45 ° and have a length 38 of approximately 15 mm in a cross section parallel to an end face.

  • the formwork profiles of the first group are also referred to as transverse abutments and the formwork profiles of the second group as longitudinal abutments.
  • the formwork profiles of the first group 2 each have on exactly one or on both longitudinal sides a protruding inclined surface for the formation of a bevel in a precast concrete part to be produced.
  • the formwork profiles of the second group 3 have on exactly one longitudinal side a protruding inclined surface for forming a bevel in a precast concrete part to be produced.

  • the formwork profiles from the first and second subgroups can be distinguished from one another because they only have a protruding inclined surface on one of the long sides and are therefore not symmetrical, so that the two end faces are distinguished by their arrangement in relation to the long side having the inclined surface .
  • the formwork profile of the first subgroup 4, which is provided with the reference number 7, has a length of 49 cm.
  • the formwork profiles identified by the reference numerals 8, 9, 10, 11, 12 and 13 have a length of 50, 51, 52, 53, 54 and 55 cm, respectively.

  • the formwork profiles of the third subgroup 6, denoted by the reference numerals 21, 22, 23, 24 and 65, have a length of 98, 147, 196, 294 and 49 cm.
  • the sub-figures a) to e) of Figure 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 (cf. Figure 2 ).
  • the formwork profiles of this subgroup differ from each other essentially only in their length 51, whereby to realize different lengths 51 the distance 54 between the two means 44 for releasably fixing the formwork profiles on a substrate is selected to be of different sizes in partial figure b).
  • the partial figure a) the Figure 3 shows a perspective view, the partial figure b) a cross-sectional view in the longitudinal direction and the partial figure c) a cross-sectional view along the sectional plane 62 shown in dashed lines in the figure b) parallel to one of the end faces 31 or 32.

  • a formwork profile from this subgroup - and the other subgroups - is essentially U-shaped in cross-section parallel to one of the end faces and has an underside 40 and an upper side 42, two end faces 31 and 32 and two intermediate longitudinal sides 27 and 28, with a protruding inclined surface 35 is provided on one of the longitudinal sides and a recess 36 for receiving an inclined surface of a formwork profile from the first group is provided on the end face 32, viewed from a direction perpendicular to one of the longitudinal sides.
  • two means 44 are provided for fixing the shuttering profiles on a ferromagnetic substrate, the means comprising an actuating element 45, accessible from their upper side 42 when the shuttering profiles are in use, as well as magnetic means 46 which can be arranged in a first and in a second operating position Magnetic means a first distance 47 to the ground in the first operating position (cf.

  • FIG. 1 The shuttering profiles 25, 7, 65 and 14 shown are shown simplified to the effect that the magazine receptacles 50 and the means 44 for releasably fixing the shuttering profiles on a substrate have been omitted. It should also be noted that the following Figures 4 to 6 Means for releasable fixing shown identical to those in the formwork profiles according to FIG Figure 3 provided means for releasable fixation are formed.
  • the formwork profiles of this subgroup differing from one another essentially in that they have a different length 52.

  • the main difference between the formwork profiles from the first subgroup (compare Figure 3 ) and the formwork profiles from the second subgroup according to Figure 4 consists in that the recess 36 for receiving an inclined surface of a formwork profile from the first group is not formed on the end face 32, but rather on the opposite end face 31.
  • the recess 36 since the formwork profiles are U-shaped in cross-section, the recess consists in that the corners of the "U" facing the subsurface are beveled on the end face 31 and at the same angle in relation to that on the end face 31, under which the inclined surfaces protrude from the long sides.
  • the length of the inclined surface running between the end face and the underside of the formwork profiles is insignificantly greater than the length of the inclined surface in a cross section parallel to the end face, so that overall there is a recess that corresponds to the inclined surface in terms of its geometry.

Figure 2 ), which, in contrast to the formwork profiles of subgroups 1 and 2, have no recesses on their end faces 31 and 32. Otherwise, the formwork profiles of this subgroup are designed similarly to the formwork profiles of the other subgroups. As it is Formwork profiles with a comparatively long length 53 are involved, with different lengths being produced by variations of the spacing 56 drawn in in partial figure a), triangular struts 64 are provided for these formwork profiles when viewed in cross section.
  • the Figures 6a ) to c) show a formwork profile 26 from the first group 2 (cf. Figure 2 ) with a total length of 57 of 300 cm. Unlike those in the Figure 1 In this case, the shuttering profile 26 has a protruding inclined surface 35 only on the longitudinal side 29. At the same time, recesses 36 are provided on both end faces 33 and 34. Due to its length, the formwork profile shown has three means 44 for releasably fixing the formwork profile on a substrate and several struts 64. Partial figure 6b) shows an enlarged detail of one of the ends of the formwork profile, the depicted detail being shown in dashed lines in partial figure a).
  • the shape of the recess 36 which is formed identically in the formwork profiles of the second group that have a recess, can be understood on the basis of this cutout.
