Definitions

  • the invention relates to components according to the preamble of claim 1.
  • Such components can e.g. have the shape of plates or boards. They can be used in particular in the field of concrete formwork. If they have the shape of plates, then they have a thickness of approximately 12-23 mm, a length in the range of approximately 60 cm to 6 m and a width of approximately 20 to 250 cm. These sizes vary from manufacturer to manufacturer. The size information is used to get an idea of the size range in which the components are used if they are panels. Roughly one can say that length and width are in the order of magnitude in the lower meter or decimeter range.
  • the components are boards, the dimensions are basically in the same range. Such boards have thicknesses in the centimeter range, lengths in the lower meter range and widths in the lower decimeter range. Boards are used in the construction industry, for example for wooden formwork beams, for example H-beams. But they can also be attached as structural boards in front of the formwork frame.
  • the object of the invention is to provide a component with which one can replace plates and boards, which is very simple to manufacture and therefore cheap.
  • the fastening aids used since then, such as nails and screws, should continue to be usable; the previous drilling techniques should also be retained.
  • the disadvantages mentioned above should at least be largely eliminated.
  • the admixture of the tape body gives the plastic, which is not usable per se, the necessary properties, so that high industrial and commercial requirements can be placed on such components.
  • claims 8 to 10 ensure that the component changes its properties little or not at all by migration of the plasticizers.
  • the tape body can be produced in a simple manner.
  • the surface of such chips is naturally very cracked and rough and, from a microscopic point of view, irregular. As a result, they bond intimately to the plastic.
  • chips are defined, as in the industrial production as waste. Depending on the desired properties of the component, one type of chip, several types of chip or all types of chip can be used in different proportions by weight.
  • the component can be given properties that the wood with its natural growth conditions can never have.
  • Claim 26 specifies a particularly tried and tested and inexpensive mixture.
  • claims 35 and 36 can improve the properties of the component with respect to compression. Compression in the material occurs when a component is bent, specifically in the area of smaller curvature.
  • the component can be used in a wide range. Depending on the choice of plastic, other resistances occur.
  • the invention is particularly suitable for components according to claim 48.
  • Components according to claim 42 are also a large field of application for the invention.
  • a plate 11 is 9 cm thick, around 2.60 m long and around 1.35 m wide. It contains 10% aluminum chips, 10% steel chips and 5% chopped glass fiber, the latter to increase the shear strength.
  • the plastic is recycled thermoplastic, which was previously granulated and largely consists of polyolefins.
  • the evenly distributed mixture was put into a mold to make the plate 11.
  • the mold had a temperature between 150 ° and 200 ° C with a best temperature around 180 ° C. The mixture stayed in the mold for about 6 minutes.
  • the press tool was cooled.
  • the specific pressure with which the pressing was carried out was between 250 N / mm2 and 550 N / mm2 with an optimum pressure in the range from 300 to 330 N / mm2.
  • the chips that can be used can be found in the book "Manufacturing Processes", Volume 1 by König, VDI-Verlags GmbH, pages 142 to 148, in particular Figure 6-24.
  • the pressing pressure was generated by a stamp which exerts pressure on one of the larger surfaces of the plate 11, perpendicular to this surface.
  • FIG. 2 shows two plates 12, 13 of this type, which were butt-connected with one end surface 14 by a weld 16.
  • the weld 16 was ground again after welding, insofar as it protruded beyond the surface boundaries of the plates 12, 13.
  • a new plate 17 of approximately 2.60 x 2.60 m has thus been created.
  • FIG. 3 shows an H-beam 18 which is frequently used in the construction industry.
  • H-beam 18 can be produced in the standard lengths of 2.45 m, 2.90 m, 3.60 m, 3.90 m, 4.90 m, 5.90 m etc. Its characteristic values are as follows: Mzul. better than 5.0 kNm, Qzul. better than 11.0 kNm, weight less than 5kg / m.
  • the height of the H-beam 18 is e.g. 20cm and the width of the boards 19, 21 is 8 cm.
  • Panels can also be designed so that they e.g. for slab formwork - in connection with the H-beams. You can e.g. replace the 22 mm thick so-called 3-SO three-layer panels and can then have panel sizes of 50/200 cm, 100/200 cm, 50/250 cm and 100/250 cm. However, the panels can also be used in formwork panels such as those used in automatic climbing machines.
  • the components produced by the invention have the advantage that they are accurate to the tenth of a millimeter and remain so.
  • the invention does not need this.
  • LDPE plastic with a density of less than 0.93 can also be used, in which case the modulus of elasticity is 170 N / mm2 and less.
  • the components can also be produced using the extrusion process. In particular, this applies to components that have a rod-like shape, such as the carrier according to Figure 3. But plates and boards can also be extruded. Then - as with all extrusion processes - the material is cut to size. However, you have to add a pressure chamber to the mouthpiece of the extruder, in which the material remains until it is solid. Such a chamber can be closed, e.g. 8 m long, and the material is then cut off in the chamber after it has hardened. The chamber is then only opened to remove one or more sections.
  • the chamber in its wall area opposite the mouthpiece of the extruder with a recess corresponding to the tear of the extruded material, so that the extruded material continuously passes through this opening into the open.
  • the material can be cut off under atmospheric pressure. Then of course you have to seal the gap between the chamber opening and the material.
  • metal strip bodies in the component which are statistically evenly distributed and are thin even in relation to the component. This can be used to heat the component. Is the component a formwork panel for concrete formwork, then you can, for example, do winter construction by contactlessly feeding the metal strip bodies with electromagnetic energy. This can be done, for example, via microwave generators, as are known, for example, from microwave ovens, or according to the induction principle, as is known both in industry and in the home. Such electromagnetic transmitters must be provided in such applications on the outer side of the formwork facing away from the concrete and irradiate the formwork panels with the waves. This has the advantage that the components remain free of electrical voltage.
