Definitions

  • the invention relates to a formwork panel with a plate which is supported and / or reinforced by a frame made of wood and / or metal and which is used for formwork encasing.
  • the plate In a formwork panel known from DE-PS 28 48 154, the plate consists of plywood. In addition to the relatively high price, plywood has the disadvantage of swelling when moisture penetrates. In the case of heavy use, the surface of the panels fray. Any holes that may become necessary can allow moisture to penetrate the inside of the slab, which can cause the slab to swell, so that clean concrete surfaces can no longer be reached. Due to the properties of the plywood panels, the life of the formwork panel is limited, screws tear out easily and the surface often bulges in the screw area.
  • the object underlying the present invention is based, a formwork panel of the aforementioned type to improve so that a long service life moisture is practically without influence on the dimensional accuracy, the possibility of nailing and screwing to be retained in the area of the plates and the formwork panel should be easy to remove, dirt-repellent and therefore easy to clean when demoulding.
  • the plate made of plastic preferably consists of PVC.
  • Polyethylene would also be suitable for use, but is much more expensive than PVC, but more wear-resistant.
  • the plastic can be reinforced with fibers in a particularly advantageous manner.
  • Thread pieces and / or tissue chips can be used for this purpose, the thread pieces being able to be approximately between 5 and 15 mm long to facilitate processing.
  • Fabrics made from natural, mineral, in particular glass, plastic and / or metal fibers or threads can also advantageously serve as fiber reinforcement. Instead of weaving, you can also use fleece mats from the mentioned materials are used. A particularly high load capacity can be achieved with low weight by using carbon fibers. With as little material expenditure as possible, an optimal increase in strength can be achieved in that the fleece or the fabric is embedded in the plastic near the surface of the plates, so that the smooth plastic surface maintains a smooth, easy-to-clean, dirt-repellent surface, so that no formwork oil or release agents must be used to make it easier to remove formwork and thus enable environmentally friendly use.
  • the fibers or tissue chips can be mixed into the plastic and the plates can be produced by extrusion.
  • the extrusion results in a certain orientation of the fibers or threads, so that the mechanical properties of the plate in the direction of the extrusion are different than at right angles to it.
  • the fabrics can have fewer or thinner threads or wires in the direction of extrusion than transversely to them, in order to achieve symmetrical properties again while maintaining the particularly favorable extrusion process.
  • Another advantage is that damage to the The surface of the plate can be easily repaired on the spot by filling and that plates which have become unusable can also be reused after being shredded to produce new plates.
  • the panels can be composed of panel strips, the panel strips then being produced by extrusion.
  • the plate strips can have lateral projections and recesses in cross section for a tongue and groove or dovetail-like connection of the plate strips.
  • the plate strips can be glued and welded together simply by assembling a tongue and groove connection, while assembling to plates by a required dovetail connection is somewhat more complex, but does not necessarily require gluing or welding.
  • the plates can have channels running parallel to one another and at a distance from the plate surfaces, which can preferably have a circular or elliptical cross section.
  • reinforcing bars can be used in at least some of the channels.
  • the reinforcing bars themselves can in turn be hollow profiles.
  • the surfaces of the plates can advantageously be provided with a layer of polytetrafluoroethylene (Teflon) in order to make it easier to remove formwork and to clean the formwork panels.
  • Teflon polytetrafluoroethylene
  • the plates are preferably formed symmetrically to their central plane, so that a further increase in the service life can be achieved by turning the plates.
  • the plate thickness can be kept small with a low weight if the frames consist of a hollow profile, and a clean concrete surface can be achieved without an edge impression if the hollow profile has a shoulder through which the outer edge of the plate is received flush. This also ensures particularly good protection of the softer plate edge against damage.
  • the panel 1 shown in Figure 1 in partial cross section consists of a metal frame 2, a hollow profile 3, which has a shoulder 4, in which a plate 5 is inserted flush with its surface 6.
  • the outer edge 7 of the plate 5 lies tightly against the projection 8 of the shoulder 4, the shoulder 4 being formed somewhat downward and laterally to bridge any tolerances, forming an L-shaped free space 9.
  • the thickness of the plate 5 corresponds to the height of the projection 8, so that the surface 6 ⁇ at least fully rests on the edge region 10 of the paragraph.
  • the plate 5 itself is fastened in a known manner to cross struts, not shown, of the metal frame 2 by means of screws.
  • the plate 5 shown in Figure 1 is made of plastic, namely PVC (polyvinyl chloride).
  • Fibers 11 are mixed into the plastic, for example textile fibers, glass fibers or, to increase the strength in particular, carbon fibers to increase the service life in the event of continuous use.
  • PVC polyvinyl chloride
  • Fibers 11 are mixed into the plastic, for example textile fibers, glass fibers or, to increase the strength in particular, carbon fibers to increase the service life in the event of continuous use.
  • metal fibers or threads can also be used.
  • the fibers or threads are of limited length. Fiber or thread lengths between about 5 and 15 mm have resulted in an optimum between workability and strength increase.
  • glass fibers or metal wires can be embedded close to the surfaces 6, 6 ⁇ , fabric 12 made of textile materials, as shown in FIG. 2.
  • parallel channels can be provided in the interior of the plate in the direction of extrusion, as indicated in FIG.
  • the channels 13 can have a circular cross section or, as shown, an elliptical cross section.
  • reinforcing struts 14 in the form of metal rods or can be placed in individual or all channels 13 Tubes may be used.
  • the reinforcing struts 14 can also be made of glass fiber reinforced material.
  • the panel 5 can be composed of panel strips 15 in a particularly advantageous manner. These can then have on their long sides on the one hand a projection 16 and on the other hand a recess 17, for example. As shown in FIG. 4 in the form of a dovetail or as shown in FIG. 5 in the form of a tongue 16 ⁇ and a groove 17 ⁇ .
  • connection can also be formed according to FIG. 6 by two longitudinal grooves 18 and an inserted material strip 19 which is approximately rectangular in cross section.
  • the spring 16 ⁇ can be glued to the groove 17 ⁇ or the material strip 19 in the longitudinal grooves 18.
  • the surfaces 6, 6 ⁇ can be provided with a Teflon coating, so that no formwork oil has to be used.
  • the hardness of the plastic material is set so that 5 nails or screws can be driven into the plates.
