  • An important object of the present invention is to provide a first correctly and perfectly positioned base grid used as a reference for the laying of cables, cable ducts, raceways, inspection wells, etc.
  • Another object of the present invention is to speed up and simplify all installation procedures.
  • Yet another object is to provide a very resistant and stable structure.
  • the new system includes a plurality of modular base elements, hereinafter simply called bases, intended to be laid on the laying surface and constrained to each other to create a modular base grid, and a plurality of modular upper elements, hereinafter simply called modules, intended to be laid on said bases and constrained to each other to create a surface on which concrete is poured, and where a service cavity is left between said modules and said bases for the passage of cables, cable ducts, raceways, etc.

  • Said connecting arms are for example constrained to said cup-shaped element-shaped element and oriented radially with respect to the latter.
  • said arms of the same base are arranged so as to be at right angles with respect to each other.
  • Said arms further comprise elements for their coupling to arms or cup-shaped elements of neighboring bases.
  • Said modules comprise a substantially flat or domed upper part, generally square or rectangular, and four support feet located at the corners of said upper part.

  • edges are channel shaped and sized so that a female channel along one edge of a module, can house a male channel along the corresponding edge of an adjacent module.
  • Said coupling channels also extend over the edges of the support feet.

  • Said coupling means are suited to prevent the arms from detaching from each other and furthermore, are configured so that once the two second ends are joined, there are no raised portions that could hinder the laying of the cables or cable ducts.
  • the first step is to lay the bases so as to create a grid where the cells are determined by said base arms, and the nodes are said regularly spaced and distributed cup-shaped elements.
  • the installers can easily lay the cables, cable ducts, raceways and the like on the grid, following the established design.
