Definitions

  • the present invention relates to accessories and construction elements incorporating one or more foamed plastic slabs which find a preferred use in building construction.
  • the present invention relates, more specifically, to a sectional nog structure for fastening a covering element to a foamed plastic slab, preferably but not exclusively of foamed polystyrene.
  • the present invention also relates to construction elements including at least one foamed plastic slab, such as, for example, lost formworks or panels employed in the construction of dividing walls, ceilings or flooring and incorporating said sectional nog structure.
  • covering element is indicated either one or more layers incorporating any material having appropriate mechanical characteristics, such as for example plaster, plastic plaster, gypsum, concrete and the like or fire resistant characteristics such as for example combinations of non-woven fabric and bitumen, or panels or slabs of an appropriate material having decorative or structural functions, such as for example panels of plaster board, wood, marble slabs, corrugated sheet metal and the like.
  • appropriate mechanical characteristics such as for example plaster, plastic plaster, gypsum, concrete and the like or fire resistant characteristics such as for example combinations of non-woven fabric and bitumen

  • the construction elements of the type mentioned exhibit characteristics of lightness, relative ease of installation and low cost, their acceptance in the field and their flexibility of use have until now been limited by the difficulty of associating in a sufficiently stable and durable manner the covering elements to the foamed plastic slab.
  • the foamed plastic employed has in itself a quite negligible ability of retaining the covering layers of plaster or concrete applied thereon, an ability totally lacking when the covering element is a wood panel or other rigid materials.
  • the constant teaching of the known art has been and is basically that of fastening the selected covering layer to the foamed plastic slab by means of a metal or plastic supporting net fixed to or supported at a short distance from the slab.
  • both the slabs are surrounded by an actual cage of electrically welded metal wires, extending parallel and transversely thereto and which fulfill the dual function of conferring to the formwork the necessary mechanical resistance to the casting and sufficient supporting capacity of the covering layer.
  • the ability to retain the covering layer is so limited that the latter consists essentially of a few millimetres of a plastic plaster layer.
  • the covering element is a rigid panel, e.g. wood
  • the technology of the industry resorts constantly either to so-called sandwich structures in which the slab is enclosed between two rigid self-bearing panels, e.g. as described in US patent No. 4,443,988, or to actual beams inserted in longitudinal grooves extending for the entire height of the slab, as illustrated for example in patent application WO 93/01371.
  • the technical problem underlying the present invention is therefore that of conceiving and making available a sectional nog structure which may embedded into one or more foamed plastic slabs, that would allow to fasten to the slab any covering element, whether formed by a layer of construction material or by a rigid panel, overcoming at the same time all the shortcomings afflicting the above mentioned known art.
  • the solution idea for such a problem is to support the covering element of the foamed plastic slab by means of a sectional nog structure comprising at least one insert flush-insertable in the slab and equipped with means accessible from outside the slab to fasten thereto the covering element, and a tierod constrained to a supporting element of the foamed plastic slab.

  • the foamed plastic slabs have a thickness of from 3 to 15 cm, chosen on a case-by-case basis, so as to ensure appropriate mechanical strength, e.g. to the cast in the case of lost formworks, as well as the desired thermoacoustic insulation characteristics.
  • foamed plastic slabs appropriately treated with suitable flame-retardant additives designed to increase the flame-resistant characteristics and fire resistance thereof.
  • the inserts of the sectional nog structure are made of an appropriate material which does not conduct heat and is preferably fire resistant.
  • the inserts are of plastic processable by moulding and preferably thermoplastic such as for example polyethylene or polypropylene or, optionally, phenol-formaldehyde resins.
  • each of the inserts is preferably equipped with a substantially cylindrical body, externally provided with means which ameliorate securing to the foamed plastic slab in which they are flush-insertable.
  • said means comprise a thread integral with the body of the insert, which at the same time facilitates insertion of the insert by screwing the same into the foamed plastic slab.
  • the insert in the slab can be equipped with lead-in holes, formed in a known manner, e.g. by milling, in accordance with a predetermined arrangement depending on the final use of the slab.
  • the means for fastening one or more covering elements to the slab protrude from a base formed in each insert at an end portion opposite the tierod and accessible from outside the slab.
  • said base also exerts the important function of retaining in position the foamed plastic slab in which the insert is embedded, facilitating the operations of manufacture, transportation and installation thereof.
  • this base preferably flattened and integral with the body of the insert, can itself constitute a support means for the covering element.
  • the base of the insert has an adequate thickness, preferably between 1.5 mm and 5 mm, such as to allow anchoring of the covering element, e.g. a plaster board panel, by means of screws or other similar fastening elements.
