Definitions

  • the invention relates to formwork with formwork panels which can be joined together at the edges and which have fastening means for releasable connection to one another.
  • Such formwork is known from German patent specification 21 37 505, in which the edge webs of the formwork panels to be connected have keyhole-like perforations for a push-through fastening bolt.
  • a tensioning device for fastening squared timber or the like on the side of formwork panels facing away from the concrete which, in addition to a clamping bracket, has a tab-like holding element which is anchored with a bolt to a perforation of a stiffening web of the formwork panels can.
  • the invention is therefore based on the object of creating a formwork of the type mentioned at the outset in which the connection of the formwork panels can be carried out more quickly.
  • the solution to this problem is that at least some of the fasteners are magnets. Since the magnets only have to be brought together with their corresponding counter surface and then apply the fastening forces themselves, the complex insertion and tightening of mechanical fasteners is eliminated. In this way, a considerable simplification of the construction of a formwork can be achieved, above all where it is only a matter of holding the parts together under a relatively low load.
  • edges of the formwork panels that can be joined together each have positively fitting profiles for absorbing forces that run transversely to the formwork skin.
  • the magnets can hold these profiled edges together, while the profiling can absorb large lateral forces.
  • the profiles of the edges that can be joined together can be shaped correspondingly to a tongue and groove connection. These profiles can either run over the entire length of the edges or can be provided at intervals from one another.
  • Mechanically fastened straps can be provided to support the magnetic couplings. These tapes are often required to stiffen the formwork and, in the case of magnetic coupling of the individual formwork panels, can also absorb tensile forces running in the direction of the formwork.
  • the straps thus have an additional function in which they brace the formwork in a known manner, but additionally support the magnetic holding forces on the connected formwork panels and can absorb loads which extend in the direction of the strapping and exceed the magnetic holding forces.
  • magnets are embedded in the edges of the formwork panels at corresponding locations or can be used detachably.
  • a magnet with reverse polarity can be inserted or used on the adjacent switchboard.
  • the magnetic forces can be added, so that relatively high holding forces arise.
  • a switchboard it is also possible for a switchboard to be attached to a switchboard provided with magnets, at least in the area of the magnets, to have ferromagnetic plates, webs or the like, preferably ferromagnetic edge webs.
  • magnets at least in the area of the magnets
  • ferromagnetic plates, webs or the like preferably ferromagnetic edge webs.
  • a modified embodiment can consist in that at least one edge web of a formwork panel itself is designed as a magnet, the edge segment of a neighboring formwork panel to be attached to it being made of ferromagnetic material or even as a magnetic strip opposite magnetization can be formed.
  • edge webs having magnets are indented in the area of the magnets and the depth of the indentation is filled in by the respective magnet, so that a rectilinear, continuous ferromagnetic web can be attached to a neighboring switchboard .
  • detachably attachable magnets can preferably be releasably attachable to indented areas of the edge webs of formwork panels, preferably by means of clips or the like.
  • a further embodiment of the formwork according to the invention can consist in that magnets are embedded or attachable on its rear side facing away from the concrete surface, so that additional parts can be fixed at least partially by means of magnetic force.
  • the edge webs and / or rear areas of the formwork panels can have perforations, hook-shaped webs in cross section or the like.
  • Mechanical fastening means This allows a combination of mechanical and magnetic fixation, the magnetic fixation allowing a very quick and easy fixation or pre-fixation, which can then be reinforced by mechanical means, provided the magnetic holding forces do not correspond to the intended loads.
  • the shuttering times could be considerably reduced by using the highly developed magnetic technology, which has been known for a long time.
  • Formwork is formed by assembling individual formwork panels 1 at their edges 2. This creates a closed formlining that corresponds to the surface to be concreted. This is also the case with the three exemplary embodiments shown in the drawing according to FIGS. 1-4.
  • the fasteners used to connect the edges 2 of the formwork panels 1 are magnets 3.
  • edges 2 of the formwork panels 1 which can be joined together each have form-fitting mating profiles for absorbing forces running transversely to the formlining.
  • the profiles of the joinable edges 2 are shaped accordingly in this case by a tongue and groove connection.
  • the magnet 3 is located at the deepest point of the edge 2, which has the groove.
  • tongue and groove that is to say the profiling of the edges 2 could extend over the entire extent of the formwork panel edge or else only be provided in partial areas.
  • FIG. 2 shows an embodiment in which edge webs 4 protrude beyond the back of the formwork panel 1 and there the magnet 3 for the magnetic one Have clutch.
  • This has the advantage that the edge webs 4 can have an additional stiffening effect. Nevertheless, in this case too, a profiling of the edge webs 4 analogous to the profiling shown in FIG. 1 can serve for a positive connection in the transverse direction to the surface of the formwork panels 1.
  • FIG. 3 shows an arrangement in which the edge webs 4 having magnets 3 are indented in the area of the magnets 3, the depth of the indentation 5 being filled by the magnet 3.
  • a rectilinear, continuous ferromagnetic edge web 4 can be added to an adjacent control panel, as illustrated in FIG. 3.
  • FIG. 4 shows the possibility of using detachably attachable magnets 3, in which case these can be detachably attached to the indented areas 5 of the edge webs 4 by means of clips 6.
  • the bracket 6 and the plug connection is illustrated in FIG. 4.
  • the formwork the formwork panels 1 of which can be coupled with the aid of magnets 3, can be used to support the This magnetic coupling can be provided with mechanically fastened straps. Tapes and the like are often required to stiffen the formwork and can therefore take on an additional function in this case.
  • a switchboard 1 which can be attached to a switchboard 1 provided with magnets 3 has ferromagnetic plates or webs in the region of the magnets 3, in the exemplary embodiment ferromagnetic edge webs 4.
  • a magnet 3 it would also be possible for a magnet 3 to be inserted or inserted at the one switch panel 1 at the point where a magnet 3 is inserted or inserted, and a magnet with reverse polarity is inserted or inserted at the adjacent switch panel.
  • At least one edge web 4 of a control panel 1 itself is designed as a magnet, the edge web 4 of the neighboring control panel to be attached to it being made of ferromagnetic material or even being designed as a magnetic strip with opposite magnetization.
  • Fig. 3 you can see in a schematic representation on the back of the formwork panels 1 further webs 7; which can serve to stiffen the actual formlining.
  • further magnets can be embedded or - e.g. B. releasable - be attachable so that additional parts can be at least partially fixed with magnetic force.
  • additional parts can be holders for squared timbers, consoles, supports or the like. It is then expedient if the edge webs 4 and / or other rear areas of the formwork panels 1 have, in addition to the magnetic fastening means, perforations, cross-section-shaped webs or other mechanical fastening means which can absorb correspondingly large loads.
  • the erection and erection of the formwork can be facilitated and accelerated in an advantageous manner, because with the help of the magnets 3 it is initially possible to "stitch" the individual parts together, with the magnets being appropriately designed and subjected to a corresponding load in many cases can suffice.
  • additional mechanical aids such as tapes, additional clamps or possibly also bolt connections can be provided, which, however, only have to support the magnetic forces, so that they are required in fewer numbers than in the case of a purely mechanical one Connection. If taping is required, there is no additional mechanical holding effort for the formwork panels, since then the magnetic forces are sufficient and loads exceeding the magnetic forces can also be absorbed by the taping.
