Definitions

  • the present invention relates to a formwork panel for system and large-area formwork with a formwork panel made of plastic and a method for its production.
  • Formwork panels for system and large-area formwork consist of a frame made of metal and / or wood on which formwork panels made of plywood or chipboard are mounted.
  • a major disadvantage of these known formwork panels or formwork panels is that they are damaged by abrasion and mechanical injuries from nails, vibrating bottles, etc. The panels are exposed to the weather and otherwise come into contact with water on the components. By absorbing water, these known formwork panels swell in length and thickness, which quickly renders them unusable leads, so that an exchange with a new record becomes necessary.
  • rolled slabs create a bad joint pattern in the concrete parts that are switched with them.
  • the length growth of the plywood formwork panels due to the water absorption also causes the frame of the formwork panel to be deformed especially at the edge, so that the connection points of several formwork panels connected to one another in system formwork have leaky points. Cement milk can escape at these leaky areas, which leads to bleeding of the concrete in this area and consequently to a deterioration in the quality of the concrete.
  • a particular weak point in formwork panels is their edge or edge area, since these areas are exposed to special mechanical loads on the one hand and the many end-grain layers are very absorbent on the other. Sealing the entire panels and in particular these areas with silicone or the like only extends the service life of such formwork panels only insignificantly.
  • waste PVC granulate is foamed by means of a foamable plastic results in comparison conventional formwork panels made of plastic reduce weight while maintaining mechanical stability.
  • a foamable plastic as a binder, the costs are also reduced since less binder is required.
  • the composition of PVC granulate which is obtained when copper is recovered from electrical cables, varies widely.
  • PVC polyvinyl graft copolymer
  • textiles e.g. from cable identification threads -
  • metal parts especially copper, and other foreign substances.
  • other plastic wastes are also suitable which correspond in their physical and surface chemical properties to this PVC granulate.
  • shredded plastic bottles such as those used for dishwashing and liquid detergents, or shredded plastic dishes, etc., can also be used instead of PVC granulate or in addition. Since the PVC granulate or corresponding plastics do not react with the foamable binder, the extremely different composition does not interfere or the use of plastic waste of very different composition, which can also be contaminated, is possible.
  • Polyurethane has proven to be particularly suitable as a foaming binder.
  • the panel is provided with a protective coating, which increases the service life the formwork panel extended.
  • this protective cover can be made of polyurethane, which can be sprayed on, spread on, rolled up or cast.
  • the protective coating can also be in the form of a wood veneer layer, a glass flow, a plastic flow, a net, etc.
  • hollow glass beads and / or silicon and / or metal chips and / or mineral substances and / or plastics and / or the fibrous substances are added to this protective coating to increase the abrasion resistance.
  • tensile impact agents are added to the PVC granulate to improve the screen line and / or to increase the stability.
  • additives are finely ground tire rubber, quartz sand, light additives, e.g. Hollow aluminum silicate.
  • reinforcement is penetrated in the embodiment according to claim 7.
  • This reinforcement can consist of a glass, plastic or metal mesh.
  • Lattice structures made of metal or plastic or hollow profiles made of metal or plastic are also suitable.
  • the reinforcement in the form of metal bars or in the form of a metal grid is not poured into the formwork panel, but is only on the side facing away from the concrete Formwork panel, i.e. mounted on the back of the formwork panel. Since a reinforcement, in particular made of metal, always represents an additional weight, the formwork panel can be used with or without reinforcement as required.
  • edge protection is provided according to claim 8. According to the advantageous development of the invention According to claim 10, this edge protection consists of a particularly resistant plastic which is finally cast into the surface of the formwork panel flush with it.
  • the formwork panel can be designed in the form of integral foam.
  • This embodiment has the advantage that the abrasion-resistant protective coating cannot be produced in a separate operation but during the molding of the plate by producing a highly compressed foam on the surface.
  • the edge protector can also be produced in this way at the same time as the plate is manufactured.
  • the front of the plate ie the side of the plate that comes to rest on the concrete, is profiled in the embodiment according to claim 12, so that any structure can be given with the exposed concrete created with such formwork panels.
  • Claim 13 teaches an advantageous method for producing a formwork panel according to the invention.
  • the subclaims 14 to 16 relate to advantageous developments of this method.
  • the frame serves as the shape for the formwork panel, i.e. the formwork sheet is foamed directly into the frame. This eliminates the need to fasten the formwork panel to the frame, since the formwork panel adheres excellently to the metal frame when it is not yet solidified.
  • Claim 17 is directed to a formwork panel which has the formwork panel according to the invention.
  • Claim 18 claims a formwork panel, in particular with a formwork panel according to one of the preceding claims, which is characterized in that the edge side of the formwork panel is flush with the frame or protrudes slightly above the frame.
  • This configuration ensures that the individual formwork panels lie close together when the formwork panels are assembled. Since plastic and in particular formwork panels made of plastic according to one of the preceding claims have a certain basic elasticity, a homogeneous concrete surface is achieved almost without annoying joint marks. This makes it possible to use formwork panels of different sizes without recognizing the different sizes on the concrete surface. Basically, an orderly joint pattern is guaranteed. At the same time, the directly adjacent formwork panels prevent cement milk from escaping in the joint area and thus preventing the concrete from bleeding out in this area.
  • the seal between the individual formwork panels or formwork panels is further improved in that the individual formwork panels are provided with sealing lips.
  • these sealing lips at least partially cover the frame, which leads to a further improved sealing and also prevents contamination of the covered part of the frame.
  • dried concrete residues can be removed from the sealing lips made of plastic much more easily than from metal due to the poorer adhesion.
  • concrete residue dried on the metal frame is often removed by hammer blows, which ultimately leads to a deformation of the frame and thus to an impairment of the function of the formwork plate.
  • This disadvantage is avoided by covering the parts of the frame that come into contact most often with liquid concrete.
  • the sealing lips can consist of the same material as the formwork panel itself or of a different plastic.
  • the sealing lips or the layer covering the frame are preferably made of pure PVC.
  • the advantageous development of the formwork panel according to claim 21 takes into account the fact that the mechanical loads in the edge region of the formwork panel are greatest.
  • this configuration facilitates the assembly of the formwork panel on the frame, in particular if the formwork panel is simply glued to the frame.
  • the formwork panel completely encloses the frame with its edge region.
  • the advantageous embodiment of the invention according to claim 23 improves the cohesion between the frame and the formwork panel. This configuration is particularly advantageous if the plate and frame are glued together.
  • the frame of the formwork panel according to the invention can also be provided in the usual way with cross struts.
  • the frame can also have breakthroughs for tension rods and reinforcements for conventional spacers.
  • the formwork panels according to the invention can of course also be used otherwise, e.g. use as a fence or as outdoor flooring, etc. Compost containers and the like can also be produced from this plastic material.
  • Fig. 1 shows a part of a formwork sheet 1 according to the invention.
  • Fig. 2 shows a section through the formwork sheet 1 according to Fig. 1.
  • the formwork sheet 1 is made of PVC granulate, which is obtained when copper is recovered from electrical cables. This waste PVC is foamed into PU foam.
  • PVC granulate obtained when copper is recovered from electrical cables.
  • This waste PVC is foamed into PU foam.
  • polystyrene or polyethylene wastes or all plastic wastes are also suitable which have the same physical or surface chemical properties as the PVC granules and may be very dirty.
  • wood waste such as Sawdust can be poured or foamed into the PU foam.
  • other foamable plastics such as Use thermoplastics.
  • the formwork panel 1 shown in Fig. 1 and 2 is in front and back 3 and 5 with a reinforcement in Form of a metal mesh 7 provided.
  • This reinforcement serves to improve the mechanical stability and can also consist of a glass or plastic fabric. Fibers or fibrous materials can also be embedded or foamed in as reinforcement.
  • a protective coating 9 is applied over the metal mesh 7.
  • the protective cover 9 consists of a particularly abrasion-resistant material, e.g. Polyurethane mixed with mineral or fibrous substances or metals. Even if this is not so clearly expressed in FIG. 1, the protective covering 9 completely covers the formwork panel 9, also and particularly on the edge sides 6 of the panel.
  • Fig. 3 is a sectional view of a record 1, which is provided with an edge protector 11.
  • the edge protector 11 is rectangular and covers the edge of the formwork panel 1 and, with approximately the same length, the front of the record 1.
  • the edge protector 11 is either made of a particularly resistant plastic, such as Polyurethane, acrylic butadiene styrene, polystyrene or metal.
  • Fig. 4 shows a section through a formwork panel 1 in which cavities 13 are provided.
  • the cavities 13 serve on the one hand to reduce weight and, on the other hand, reinforcements, for example in the form of tubes 15, can be introduced into these cavities if required.
  • Fig. 5 shows a further variant of the formwork sheet 1, in which a reinforcement in the form of flat iron 17 is poured or foamed.
  • the flat band irons 17 are aligned parallel to the edge sides 6 and are completely enclosed by the plastic mass of the formwork panel.
  • FIG. 6 A further embodiment of the formwork panel 1 is shown in FIG. 6.
  • a reinforcement in the form of metal rods 19 is only attached to the back 5 of the formwork panel 1. So that this type of reinforcement does not require a change in the frame of a formwork panel equipped with it, the metal bars 19 run in recesses 21 in the formwork panel 1.

  • the embodiment of the formwork sheet according to FIG. 8 corresponds to the embodiment of FIG. 7 with the difference that the sealing lip 24 not only covers the edge sides 6 of the formwork sheet but also completely one of the longer sides of the hollow profile 26.
  • the embodiment according to FIG. 8 enables a simplified cleaning of the formwork panel, since the largest part of the metal frame is covered by the sealing lip 24 made of plastic and dried concrete residues can be removed from plastic much more easily than from metal.
  • the embodiment of the formwork panel according to FIG. 9 also corresponds to the embodiment according to FIG. 7 with the difference that the sealing lip 24 completely surrounds the frame 26 or the hollow profile 26. In this embodiment, it is completely prevented that concrete residues can solidify on the metal frame 26.
