Definitions

  • the invention relates to a formwork element, in particular a formwork panel according to the preamble of patent claim 1 and a method for producing a formwork element according to the preamble of patent claim 12.
  • edge protection made of plastic which essentially serves to damage the edges of the formwork elements by a higher mechanical wear resistance of the edge protection made of plastic
  • edge areas of such shuttering elements are exposed to high mechanical stresses, in particular when constructing or dismantling a formwork construction, in particular at the edges, and any damage to the edges that is occurring adversely affects the quality of the concrete structures produced with the formwork elements, since at joints between two formwork elements in edge damage projections or protrusions are caused on the finished component surface, which must be laboriously removed after disassembly of the formwork and therefore costly.
  • the freedom from damage to edges is therefore an important criterion for the service life of such formwork elements.
  • the edge protector made of plastic should furthermore prevent moisture from penetrating over the edge surfaces of a formwork element, since the absorption or release of moisture can cause swelling or shrinkage of the base body made of wood and / or wood material, since this likewise affects the surface quality a concrete component produced therewith may adversely affect and beyond the mechanical strength of the formwork element due to degradation processes of the natural material wood, especially decay processes can be greatly accelerated, whereby the service life of a formwork element is also disadvantageously reduced.
  • DE 2 305 797 AI known to attach to edge Schmalfizzen a formwork panel made of wood along the edges of the plate edge of plastic.
  • the edge cover layers have a central web projecting at right angles and engaging in an edge groove of the shuttering panels, and on the surface on which the edge cover layers bear against the wood core of the shuttering panel, the edge cover layers are glued to the wood core.
  • the wood core is provided to protect against moisture on the Plattenfizze at least on one side with a flat cover layer of plastic and to prevent ingress of moisture into the wood core, the at least one cover layer in the region of their abutting surfaces at their outer edges with the adjoining edge coats glued or welded.
  • DE 26 18 366 AI discloses a formwork panel with a circumferential edge protection of elastically yielding material, which is fixedly connected to the Schalfiumblee donating panel.
  • more elastic material can be arranged at the corners, in that the edge protection has a larger cross section in the area of the corners.
  • the edge protection can protrude slightly up to 0.5 mm above the actual formwork surface, so that elevations on the finished Betonoberfikiee be avoided, the edge protector is preferably formed flush with the formwork surface, as a result the junction of two formwork panels only gives a sign.
  • the object of the invention is to provide a formwork element with an edge protector as well as a method for its production in which, despite the use of economic manufacturing methods, a high mechanical strength of the edge protector and a good protection against moisture penetration into the formwork element is achieved ,
  • the object of the invention is achieved by a formwork element with the features of the characterizing part of claim 1 and by a method with the characterizing measures of claim 12. Due to the fact that the first protective edge section is substantially flush with the plate surface and the second protective edge section has a raised section that is raised relative to the plate surface of the basic body, in particular by at least 0.5 mm, the corners of such a shuttering element formed by the second protective edge sections are thus somewhat thicker than the main body and the first protective edge sections. On a concrete surface produced therewith, this results in the corner regions of the formwork element with the elevations corresponding, slightly recessed sections that either do not interfere with the finished surface or can be filled by simply filling.
  • the essential advantage of the elevations consists in the fact that the corner regions of the formwork element do not spring back or recessed relative to the plate surface of the base body and thus no local elevations arise on the finished concrete surface, even if in use the base body is thick due to the influence of moisture Swelling processes increases or the corner areas as the most heavily loaded zones of the formwork element have a greater wear than the main body or the first guard edge sections.
  • Cantilever sections consists of air gaps being formed between plate surfaces facing one another in stacking elements formed in this way, which facilitate evaporation of moisture from the base body over the plate surfaces and thus waterlogging and the corresponding negative and life-shortening effects on the wood or wood-based materials the shuttering element can be reduced.
  • the cantilever portion is in particular raised between 0.5 mm and 2 mm with respect to the plate surface of the formwork element.
  • the protective edge in the corner sections has a greater thickness, which causes better damping and cushioning of shocks and at the corners impinging shocks are distributed over a larger area of the edge surface, whereby a correspondingly lower risk of damage to the Basic body is given.
  • the thickness of the protective edge may be greater than 15 mm in the corner regions measured from the edge surface to the corner.
  • a cantilever portion on a plane parallel to the plate surface fürhöhungs Colour which extends to the corner of the shuttering element.
  • a load occurring in use and thereby causing wear of the As a result, the superelevation section is distributed more uniformly over a larger area, and the overhang in the corner areas is thus retained longer, even under harsh operating conditions.
  • stacked formwork elements are stacked on each other more stable.
  • the superelevation section uses up slowly accordingly and the elevation with respect to the plate surface remains in use for longer in use than in the case of a more punctiform formation of the superelevation section.
  • An embodiment of the superelevation surface according to claim 5 is simple to manufacture and results in the finished concrete surface in addition visually appealing depressions, which, however, are also easy to spill out if necessary.
  • a ramp-like running from the level of the disk surface to the superelevation surface is simple to manufacture and results in the finished concrete surface in addition visually appealing depressions, which, however, are also easy to spill out if necessary.
  • Transition surface on the second guard edge portion causes both the formwork element as well as on the finished concrete surface, a gradually increasing transition between the plate surface and over-elevation portion is formed and no abrupt transition with sharp edges or steps is present.
  • problems in handling the formwork elements such as e.g. avoiding catching of the overhanging portions at edges etc.
  • an embodiment according to claim 7 whereby a slowly rising from the level of the plate surface to the level of the superelevation surface transition surface is given, which also on the finished concrete surface smooth and stepless transitions causes that Corpschalen easily and are not outbreak prone. Furthermore, such an embodiment of the transitional surfaces that hooking of the overhanging portion is prevented at other edges largely.
  • An embodiment according to claim 8 is also advantageous in terms of manufacturing technology since it also gives a symmetrical distribution of material in the second protective edge section and, in use, the most uniform possible wear of the overhanging sections takes place. Furthermore, this results in the finished concrete surface pleasing shapes of the wells, which can also be simply filled out.
  • the embodiment of the formwork element according to claim 9 is advantageous, since both sides of the formwork element can be used while still achieving similar surfaces in the area of the corners. The thus possible turning of the formwork elements thereby also causes a further increase in the life.

  • a high degree of flexibility of the shape configuration of the raised portions and excellent adhesion of the second protective edge portions to the edge surfaces or to the outer sides of the first protective edge portions are achieved by the measure of claim 13.

  • the execution of the corner sections is independent of the lengths of the first guard edge sections and can thereby be used for all plate dimensions, the injection molding tool used in this case.
  • the implementation of the method according to claim 15 requires particularly low mechanical investment for the attachment of the first protective edge portions, since they are attached in the first manufacturing step only to the straight rectangular edges, for example by means of a continuous process and using prefabricated edge material, and the corner sections only in a second Manufacturing step are provided with the second guard edge portions, which are attached directly to the edge surface of the body.
