Definitions

  • the present invention relates to a covering element according to the preamble of claim 1.
  • Covering elements are used to accommodate passenger loads and vehicle loads on structures. Structures such as bridges or footbridges are used. With regard to the structural safety, proof of the load-bearing capacity under certain individual loads and distributed loads must be provided. With regard to the suitability for use, proof of the short-term load capacity under certain distributed loads must be provided.
  • the covering elements do not represent the main support structure, but only the secondary support structure.
  • the main support structures such as the steel or Wooden frameworks from bridges are covered with the covering elements after erection.
  • the maintenance and maintenance work on these covering elements is associated with considerable effort in conventional constructions.
  • the conventionally used covering elements which mainly consist of wood, metal or concrete, have disadvantages in terms of weight and / or service life.
  • Normal wood on the other hand, has a much shorter lifespan and must be replaced every 5 to 10 years. Elements constructed in this way must also be made non-slip here.
  • Metal is often used as the material for the covering elements, especially for smaller dimensions and loads, such as for personal bridges.
  • a grating construction is often used for reasons of weight, but this is not without problems especially when used for people.
  • the grating construction allows a deep view, which can lead to dizziness and discomfort.
  • the slip resistance due to the small webs of the grille is also limited, in particular too small for small contact surfaces, such as for two-wheelers.
  • the object of the present invention was to find a covering element of the type mentioned, which has a long service life for a given load.
  • the covering element By designing the covering element as a hollow profile with reinforcing ribs in the top and bottom surfaces, high strength and resilience are achieved with low weight.
  • the reinforcing rib is used for the longitudinal stiffening of the profile and absorbs the transverse forces, while the reinforcing ribs the pressure or. Absorb tensile forces and a bulge of the deck or Prevent floor space.
  • plastic in particular fiber-reinforced plastic
  • Such an element thus achieves a very long service life, which advantageously reduces the maintenance and maintenance costs of structures equipped with such covering elements.
  • Covering elements of this type are advantageously suitable for use as bridge coverings for pedestrians and two-wheelers, and can also be easily installed thanks to the low weight. Scaffolding, stage construction, exhibition construction, balcony or terrace construction, railing construction or the like can also be used as further areas of application.

  • the reinforcing ribs 4, 5 are formed continuously over the entire length of the covering element and run parallel to the side walls 7, 8.
  • the outside of the top surface 1 is profiled, advantageously by providing longitudinal grooves 9 running parallel to the side walls 7, 8. These longitudinal grooves 9 make the covering element non-slip and are therefore particularly suitable for use by people or two-wheelers.
  • Profile cross section or fibers with a high tensile strength are used along the profile.
  • these can be carbon fibers or appropriately reinforced glass fibers. These are advantageous on the outer edges of the reinforcing ribs 4, 5 and / or the corner regions of the profile cross section, ie the transition between the side walls 7, 8 and the top surface 1, respectively.

  • Covering element two or more connecting webs 6 may be formed, as can be seen from the representation of the cross section of a further covering element designed according to the invention in Figure 2.
  • the covering element according to the invention provides a light, rigid construction, which is particularly, but not exclusively, suitable for use as a bridge covering for pedestrians and two-wheelers.
  • the covering element is characterized by its low weight, easy handling and simple installation options.

Abstract

L'invention concerne un élément de revêtement de forme sensiblement rectangulaire, présentant une surface sensiblement plane destinée à recevoir des charges superficielles et ponctuelles. Cet élément de revêtement est conçu sous la forme d'un profilé creux pourvu d'au moins une cavité (3, 3') et présente une section transversale sensiblement rectangulaire. Les faces supérieure et inférieure (1, 2) du profilé présentent des nervures de renfort orientées vers l'intérieur (4, 5). Ledit élément de revêtement est avantageusement constitué de matière plastique renforcée par des fibres et présente, au niveau de ses zones fortement chargées, davantage de renforts ou des fibres pouvant supporter des charges plus lourdes qu'au niveau des autres zones dudit profilé. Ainsi, cet élément de revêtement a l'avantage de présenter une stabilité et une force portante particulièrement élevées pour un poids faible ainsi qu'une très longue durée de vie grâce à une résistance à la corrosion et à une stabilité aux intempéries élevées.
