Definitions

  • Iron bridges tend to rust and resulting in that they need to be painted, repainted and repaired on a regular basis.
  • any large construction element of e.g. concrete or steel which is not easily replaceable and being subjected to weather will suffer from undesired maintenance cost as described above.
  • Examples of such large construction elements are sections of buildings, fagades, beams and pillars.
  • the load bearing shell may follow a contour of the core structure, which is advantageous in that the core structure may be used for shaping the load bearing shell.
  • the reinforcing fiber material may be in the form of a woven web or a unidirectional web, which is advantageous in that the reinforcing fiber material may be provided in a conventional manner, where the web is cut to a desired size and shape.
  • the term "unidirectional web" may be any web where the fibers are not woven, but provided side by side in a common direction.
  • the unidirectional web may however, comprise a plurality of layers of fibers provided side by side in a common direction, where the fibers of the respective layers may be provided at different angles, e.g. 0 degrees and 30 degrees.
  • a bridge comprising at least one construction element of the above type.
  • features of this aspect of the invention provide similar advantages as discussed above in relation to the previous aspect of the invention.
  • a bridge which is less sensitive to wind and corrosion may be provided.
  • a method for fabricating a construction element comprises the steps of: providing a core structure formed of porous concrete as a major component, arranging a reinforcing fiber material and a non-hardened matrix material in a sandwich arrangement on the core structure, hardening the matrix material, thereby forming, on the core structure, a load bearing shell comprising a composite material sandwich structure comprising the hardened matrix material and the reinforcing fiber material.
  • a construction element may be fabricated in an efficient way.
  • a core structure formed of porous concrete as a major component is provided.
  • the step of providing a core structure may be preceded by a step of pouring or casting the core structure, or shaping a block of porous concrete into the shape of the core structure by grinding, cutting, milling, or combinations thereof, which is advantageous in that conventional methods may be used to manufacture the core structure.
  • Fig. 5 is a flow chart of a method according to the invention.
  • the unidirectional web 302 of glass fiber comprises two layers of glass fibers.
  • the fibers in each layer are arranged in a common direction while the two layers are arranged in a 90 degree angle with respect to each other.
  • the unidirectional web 302 of glass fibers is arranged such that the fibers of the respective layers are extending in a ⁇ 45 degree angle with respect to the longitudinal direction L of the construction element 100 and core structure 101 .
  • the depicted bridge 600 is a road bridge used for letting a road 604 pass over the waterway 602.
  • the bridge includes two construction elements 100 of the type depicted in Fig. 1 .
  • Each of the construction elements 100 spans the entire length of the bridge 600.
  • the construction elements 100 are arranged side by side such that each construction element 100 carries one lane of the road 604.
  • the construction elements 100 are provided with a road surface 606 on their respective top surfaces.
  • the road surface reduces wear to the construction element 100 and increases the friction.
  • the road surface is preferably made of asphalt or concrete.
  • the respective construction elements 100 may be handled and transported although typically having a length in the longitudinal direction L of 4 to 100 m. This is possible due to the fact that the respective construction elements 100 may be fabricated using a relatively speaking light material.
