Definitions

  • the invention relates to formwork and in particular to a quiver formwork for concrete construction.
  • Quiver formwork is known from a formwork material with a corrugated sheet-like structure or with a corresponding profile, d. H. Corrugation that gives the material the required rigidity.
  • quiver formwork are used for. B. used in the creation of individual foundations, foundation slabs or generally in concrete parts where there is a recess on a surface for later connection of e.g. columnar concrete element should be kept free.
  • 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 appropriately connecting the two blank ends, the profile 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, so this bending requires high forces when manufacturing the formwork. Furthermore, the bending in any case leads to a widening of the material in the region of the bend due to the flattening of the corrugation at the bending line in question, so that it is also extremely difficult to produce dimensionally correct formwork elements or formwork. In particular, an increase in the width of the formwork material in the area of a bending line is not permissible, in particular in the case of formwork elements or formworks that are like e.g. B. Quiver formwork in a concrete component on a surface there for the connection of a later concrete component to keep openings open.
  • the object of the invention is to show a formwork which has improved properties compared to the known.
  • the formwork material can be bent or angled around a bending line running perpendicular or perpendicular to the profile, despite having sufficient rigidity for the production of the formwork or a formwork element, without the harmful widening of the material when bending or kinking in the area of the respective bending line occurs.
  • the 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 structure 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 formwork according to the invention is a quiver formwork. This then 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 profiling.
  • a 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.
  • 1 is a formwork material in the form of a profiled steel sheet.
  • the untreated or treated, for example galvanized, on its surface sides Sheet steel is provided with a dovetail-shaped profiling, ie the formwork material 1 has a plurality of dovetail-shaped profile sections 2, which extend over one side of the formwork material 1, ie in the illustration chosen for FIG. 4, over the underside of this formwork material or over a plane defining this side E stand out and each extend in an axial direction X over the entire length of this formwork material.
  • the axis direction X lies together with the perpendicular axis direction Y in the plane E.
  • a further profile section 5 is formed between each two profile sections 2, with all the profile sections 5 on the other side, ie the plane E 'enclosing the surface areas 3. H. 4 protrude beyond the plane E 'of the top 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 enclose the leg areas 4 with the surface areas 3 and 6 so that one profile area 2 of the somewhat larger profile areas 5 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 produced 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 on 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 area of the angling 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 formwork formwork 10.
  • the outer formwork 9 is created on a base defined by the drawing plane of FIG. 3 from four larger blanks 9 'of the formwork material 1.
  • the quiver formwork 10 is composed of two similar formwork elements 10a, each of which is made from a blank of the formwork material 1 as an angle piece or by angling this formwork material perpendicular to the profiling in such a way that each formwork element has two legs 10a 'and 10a' ', which at of the embodiment shown have the same width in the direction perpendicular to the bending line 12 and each have an angled portion 13 at their edges remote from the bent line 12, which run parallel to this bent line, in such a way that each angled portion 13 with the outside of the associated leg 10a 'or 10a '' encloses an acute angle.
  • 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 the square interior of the quiver formwork 10 and the adjoining legs of the formwork elements 10a touch in the area 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 to the quiver formwork 10 at the place of use by the connecting elements 14, 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 the plane E, that is to say upward in the illustration chosen for FIG. 6, and which form a further, also 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 formwork material is each provided with a bent longitudinal edge 19 or 20, which is formed by bending the material by 180 ° and has a leg 19 'or 20', which is in the plane E or parallel to this level at a distance from the subsequent formwork material.
  • the leg 19 ′ is approximately an amount that corresponds to the sheet thickness of the formwork material 1 a, Provided above the plane E, namely below the part of the formwork material 1a adjoining the leg 19 '.
  • the circuit material in the area 17 is angled or profiled in a Z-shape.
  • 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.
  • two or more blanks of the formwork material 1 a can then be connected to one another in a form-fitting manner, before the formwork material is bent or bent.
  • the blanks of the formwork material 1a which are connected to one another via the bent longitudinal edges 19 and 20 are bent transversely to the profile, that is to say transversely to the bent longitudinal edges 19 and 20, the blanks of the formwork material 1a are firmly fixed to one another after the bend, in the same way , as is also the case with the interlocking cuts of the formwork material 1 with the profile sections 2 and 5 with the bending edge 12 or 16 extending transversely to the profile.
  • the above-described Z-shaped profiling of the area 17 on the bent longitudinal edge 19 on the one hand ensures that adjoining blanks of the formwork material 1 a lie with their planes E in a common plane.
  • the Z-shaped profiling ensures that interlocking or interconnected blanks of the formwork material 1 a on the bent longitudinal edges 19 and 20 cannot become detached from one another, not even when they are bent or bent into the formwork.
