Definitions

  • Thin-shell molded parts made of fully or partially plastic or bitumen-bonded composite materials, e.g. unsaturated polyester, polymer concrete, bitumen-bound materials and the like for applications where a relatively high bending and / or tensile stress occurs, such as e.g. For large roof covers, profiles are generally profiled to increase the section modulus and thus the rigidity.
  • the present invention therefore relates to a thin-shell molded piece made of a plastic or bitumen-bonded composite material, in particular a profiled component for high loads, which is characterized in that it is cohesively connected to a reinforcing material at least in the area of the highest critical tensile stress.
  • the invention is of particular interest for profiled fittings, such as corrugated sheets and other profiled components, such as those used for e.g. Roofs are used where there is a large bending and / or tensile stress. This applies e.g. for increased individual loads when walking on the other hand, but also allows the spans to be increased within the permissible traffic loads.
  • the reinforcement according to the invention is also advantageous for flat plates.
  • the plastic- or bitumen-bonded material which for the sake of simplicity is called “carrier material” below, can consist of unreinforced binder, possibly enriched with fillers.
  • the carrier material preferably contains a fiber reinforcement made of inorganic and / or organic fibers, which can be uniformly distributed in the mass or can also be used in the form of woven fabrics, nonwovens, fiber strands, etc.
  • All natural, semi-synthetic and synthetic materials can be used as reinforcing materials.
  • the modulus of elasticity is decisive for the mode of action of the reinforcement material. If an increase in the breaking load is required, the modulus of elasticity of the reinforcement material must be greater than that of the carrier material. If only security against tampering is required, e.g. To reduce the risk of accidents, the modulus of elasticity of the reinforcing material can be smaller than that of the carrier material.
  • a combination of reinforcement materials with different modulus of elasticity can also be used. The following are considered as reinforcement materials: fabrics, scrims, braids, nets, nonwovens, threads, fiber strands, thread sheets etc. as well as sheets, plates, foils, coatings, wires, grids etc. made of glass, plastics, elastomers, metal, ceramic material etc.
  • the undersides of the troughs are the most stressed areas;
  • the reinforcement is therefore preferably in the direction of the wave trough on the underside thereof with the help of a continuous or interrupted strip, the width of which is determined by the cross section and the tensile strength of the reinforcing material and the nature of the carrier material, respectively. of the desired degree of reinforcement.
  • the reinforcement strip can be attached to the most tensile side on one or more wave troughs and / or wave crests on the same plate side.
  • the reinforcement can be distributed evenly over the entire surface, or e.g. in the form of horizontal and / or longitudinal stripes resp. of diagonal stripes that are applied at certain intervals to each other.
  • the reinforcing material is bonded to the carrier material with the aid of a suitable high-strength adhesive.
  • suitable adhesives are e.g. those based on commercially available reactive resins, e.g. Epoxy resins, unsaturated polyester resins, vinyl ester resins, polyurethanes, etc.
  • Suitable plastics can optionally also be melted directly onto the carrier or applied in solution.
  • the reinforcement material can be provided with an additional covering layer to protect the material against corrosion etc.
  • This cover layer can also be the adhesive and penetrate the reinforcement strip entirely.
  • the example is a polymer concrete corrugated sheet in the dimensions according to SIA standard 175 consisting of 6% PMMA resin, 70% quartz sand, 19% quartz powder, 5% silica smoke.
  • the plate was covered with a 7.5 cm wide strip of glass fiber fabric, warp 7.2 threads / cm, 2 x 136 tex, weft 5 x 1 thread / cm, 2 x 136 tex, tear strength approx. .86 kg / cm, by means of epoxy - "GRILONIT" adhesive (from Ems Chemie), firmly bonded to the lower areas of the troughs.
  • the invention is not limited to the exemplary embodiment mentioned above. Similar, continuous or discontinuous processes for applying the reinforcement elements and the adhesive lead to comparable results, provided that a material bond between the reinforcement and the carrier plate is ensured.
