Definitions

  • the present invention relates to a truss bracing concrete or masoned structural layers together.
  • the invention relates also to a method for manufacturing such a truss .
  • the invention relates to a truss for a two-plate thermally insulated prefabricated element for bracing together the inner and outer layers of the element through an insulation.
  • the traditional truss has been manufactured in such a way that separate steel chords are resistance welded to a bent diagonal wire, the product being compiled from three components .
  • An object of the invention is to provide an improved truss, which is lighter, stronger with respect to its weight, builds a weaker cold bridge between the plates, and is more manufacturing friendly.
  • This ob ect is achieved by means of a truss of the invention, the characterizing features of which are set forth in the appended claim 1 or 2.
  • the truss can be manufactured preferably by means of the method defined in the appended claim 3.
  • the element consists m a conventional manner of inner and outer layers 1 and 2 with a thermal insulation 3 therebetween.
  • the layers are tied to each other by means of a truss 4, comprising boundary, substantially parallel chords 5 and diagonal braces 6 therebetween, the number of which can be e.g. three per meter in either direction.
  • the chords 5 are embedded in cast concrete and the diagonal braces 6 are set in junctures between the insulations.
  • the diagonal braces 6 and the chords 5 are manufactured from a single blank, such that there are no welding joints at crossing points 7 of the diagonal braces or at junctures 8 between the same and the chords.
  • This is made possible in such a manner that a blank of sheet material is cut to provide it with slits, the disposition of which is such that, as the blank is stretched from the chords 5 in a direction perpendicular to the slits, the diagonal braces 6 stretch to a sufficient extent for achieving a desired width for the truss.
  • the direction and positioning of the slits is such that, during the stretching, the diagonal braces cannot experience flattening or bending.
  • the blank sheet may have a material thickness which is quite small, e.g. 1-2 mm.
  • the method differs from traditional manufacturing of a meshed structure essentially in the sense that stretching of the entire slit area is effected in a single operation by distancing the chords 5 from each other while the diagonal braces remain substantially coincident with the plane of the original sheet
  • the invention offers the following advantages:
  • the invention is not limited to the above-described exemplary embodiment, but the truss can also be used for bracing on-site masoned brick walls to each other, the chords 5 being embedded in mortar between brick layers, or - in a floor slab for binding to the slab a concrete layer to be cast on top of the slab.
