Definitions

  • Such quiver formwork is known (GB-A-773 220).
  • the known quiver formwork consists of two formwork elements, each of which is made at an angle from sheet steel by bending around a bending line with two legs and is connected to one another to form the quiver formwork.
  • Profiles are provided for stiffening in each leg of the formwork elements, specifically in the form of indented ribs, which are each limited to the area of the leg in question and in particular end in front of the respective bending line.
  • Quiver formwork made of a formwork material with a corrugated sheet-like structure or with a corresponding profiling is also known.
  • quiver formworks are used for. B. in the creation of individual foundations, foundation slabs or generally used in concrete parts where a recess for later connection of a column-like concrete element, for example, is to be kept free on a surface.
  • These quiver formwork are essentially cuboid or hollow box-like with four circumferential wall sections adjoining one another at right angles and an upper and lower open side.
  • the wall sections are made from a blank of the formwork material by angling and correspondingly connecting the two blank ends, the profiling or corrugation being perpendicular to the bending line or to the corners of the hollow box-type quiver formwork for the required rigidity.
  • the well-known quiver formwork is delivered to the place of use in its fully formed state.
  • a major disadvantage is that it is difficult to bend or bend the corrugated formwork material transversely or perpendicularly to the profiling, which means that high forces are required for the production of the quiver formwork for this bending. Furthermore, the bending in any case leads to a widening of the material in the area of the bend due to the flattening of the corrugation at the relevant bending line, so that it is also extremely difficult to produce dimensionally accurate quiver formwork. In particular, an increase in the width of the formwork material in the area of a bending line is not permissible, particularly in the case of quiver formwork, which are intended to keep openings in a concrete component on a surface there for the connection of a later concrete component.
  • formworks (FR-A-13 63 439) which are produced using curved formwork elements which have a corrugated profile in a sectional plane including the axis of curvature. These known formwork elements have no bend. An angling would also mean that there would be a substantial increase in the width (in the direction of the bending edge) for the relevant formwork element in the area of the relevant bending line.
  • steel sheets with a wide variety of profiles are known, in particular also with a dovetail-shaped profile ("Stahlbau-Profiles", page 30, 14th edition 1979), and the use of steel sheets with dovetail profiling as formwork element for producing steel profile composite slabs ("Stahlbau Manual ", pages 653 - 659, Stahlbau-Verlags GmbH, Cologne 1982).
  • the known profiled sheets in particular are not angled in their use as formwork element and do not form a quiver formwork.
  • the object of the invention is to show a quiver formwork which can be produced easily and true to size by bending a profiled sheet.
  • the formwork material can be bent or angled around a bending line that runs perpendicular or perpendicular to the profile, despite having sufficient rigidity for the production of the quiver formwork, without the harmful widening of the material occurring in the area of the respective bending line when bending or kinking .
  • the quiver formwork according to the invention also has the advantage of a significantly improved integration in the concrete, so that where the formwork remains in the building between two adjoining components, there is a significantly improved transition between these components in terms of statics and dynamics can be reached.
  • the profiling has at least first profile sections and second profile sections, of which the second profile sections have a larger cross section, in such a way that a first profile section can be positively received by a second profile section in each case.
  • the quiver formwork consists of at least two angular or U-shaped formwork elements which can be connected to one another via connecting elements or preferably by plugging together on the profile.
  • a quiver formwork produced in this way has the advantage that the formwork elements can be stacked one inside the other to reduce the storage and transport volume.
  • a further profile section 5 is formed, with all profile sections 5 over the plane E 'enclosing the surface areas 3 on the other side, i. H. 4 protrude beyond the plane E 'of the upper side of the formwork material 1 and extend parallel to one another and parallel to the axial direction X over the entire length of the formwork material 1.
  • the profile sections 5 are likewise formed by the leg areas 4 and by a strip-shaped surface area 6, which extends over the entire length of the associated profile section 5.
  • the profile sections 2 and 5 are each open to different sides of the material 1.
  • the profile sections 5 are formed by a suitable choice of their width, in particular by a corresponding choice of the width of the surface areas 3, but also by a corresponding choice of the angles which include the leg areas 4 with the surface areas 3 and 6 so that of the somewhat larger profile areas 5, one profile area 2 can be positively received, as indicated in FIG. 4 by the broken line 2 '.
  • the dovetail shape i.e. H.
  • the successive profile sections 2 and 5 not only ensure the required rigidity of the formwork material 1 and not only serve to connect formwork elements in the manner described above, but also ensure a particularly positive integration of the respective formwork element in the concrete.
  • the dovetail-shaped profiling also ensures a particularly positive integration in the concrete where another concrete component is connected to a concrete component created first.
  • the formwork element made from the formwork material 1 remains as lost formwork in the transition area between the two concrete components.
  • the formwork material 1 is provided with a roughening on the surfaces, which can be designed in the most varied of ways, for example also in the form of a surface profile with a large number of projections and / or depressions.
  • knob-like projections 7 and knob-like depressions 8 are provided, the projections 7 being located on the surface regions 6 of the profile sections 5 and the recesses 8 on the surface regions 3 of the profile sections 2, so that despite the projections 7 and recesses 8 a tight fit Fitting of the profile sections 2 into the profile sections 5 is ensured. If the profile sections 2 fit into the profile sections 5 with greater play, it is in principle also possible to use them on the surface areas 3, that is to say via those in FIG Level E facing away from level E 'protruding projections and / or vice versa to provide 6 recesses on the surface areas.
  • formwork elements are produced from the formwork material 1, and in each case from a cut of the formwork material 1 by at least once angling this cut transversely to the profile, thereby overall not only the required shape for the formwork element but also to achieve the required rigidity.
  • the dovetail-shaped profiling of the formwork material 1 makes it possible to bend or bend it easily or transversely to the profiling when producing the formwork elements, since the dovetail-shaped profiling causes the material in the region of the bend in the sense of a reduction in the angle between the leg regions 4 and surface areas 3 and 6, d. H. deformed in the sense of stacking the leg regions 4 and the surface regions 3 and 6.
  • FIG. 1 shows a formwork arrangement for an individual foundation consisting of an outer formwork 9 and an inner quiver formwork 10.
  • the outer formwork 9 is created on a surface defined by the drawing plane of FIG. 3 from four larger blanks 9 'of the formwork material 1.

  • the outside is the side that faces away from the angular space formed by the legs 10a 'and 10a' '.
  • the two formwork elements 10a in which the stiffening profiling (profile sections 2 and 5) runs perpendicular to the bending line 12, are arranged in such a way that these formwork elements 10a with their legs 10a 'and 10a' 'are the same as those shown in FIG Embodiment enclose square interior of the quiver formwork 10 and touch the adjacent legs of the formwork elements 10a in the region of the bends 13.
  • a connecting element 14 in the form of a length of a C-profile onto the bends 13 of adjacent legs 10a 'or 10a' ', the formwork elements 10a are connected to each other to form the quiver formwork 10.
  • the quiver formwork 10 consists of two angular formwork elements 10a, which are only connected at the place of use by the connecting elements 14 to the quiver formwork 10, it is possible to stack the formwork elements 10a into one another for transport and / or storage and thus the transport and To significantly reduce storage volume.
  • Fig. 5 shows a top view of a quiver formwork 15, which consists of two U-shaped formwork elements 15a.
  • Each of the two formwork elements 15a is in turn made from a blank of the formwork material 1, namely by bending twice along the bending line 16, which in turn runs perpendicular to the profiling of the formwork material.
  • the formwork elements 15a are given their U-shape with two legs 15a 'and a yoke section 15a' 'connecting these legs together.
  • the two formwork elements are connected to one another to form the formwork or quiver formwork 15, which is completely closed, by pushing the profile sections 2 and 5 of the legs 15a' to be connected to one another.
  • FIG. 6 shows a circuit material 1 a which has two dovetail profile sections 2 which project laterally beyond plane E, that is to say upward in the illustration chosen for FIG. 6, which form a further dovetail profile section 5 between them.
  • the plane E is defined, inter alia, by the two edge regions 17 and 18 of the formwork material 1 a provided laterally by the profile sections 2.

  • the leg 20 lies above the plane E, namely at a distance above the adjoining part of the formwork material 1 a, which (distance) is equal to or slightly larger than the sheet thickness of the formwork material 1 a.
