Definitions

  • the present invention relates to construction elements incorporating one or more foamed plastic slabs which find a preferred use in building construction.
  • the present invention relates, more specifically, to construction elements including a pair of foamed plastic slabs, such as, for example, lost formworks employed in the construction of dividing walls, ceilings or flooring.
  • 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
  • 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.
  • composite construction elements i.e. including at least one foamed plastic slab, preferably foamed polystyrene, having the function of thermoacoustic insulation, and one or more covering elements in layers or panels of appropriate construction material, e.g. concrete, plaster, gypsum, wood and the like, imparting adequate mechanical and, optionally, decorative characteristics to the construction element, manufactured element or building.
  • 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 millimeters 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.
  • German patent application DE-A-1 938 065 discloses a construction element comprising a pair of light construction slabs mutually associated by means of a nog structure including a spacer rod irreversibly locked to supporting elements made of stainless material and supported externally to the light construction slabs.
  • US patent No. 4,040,222 discloses a wall having an outer structural component of masonry units which are provided with dovetails slots in their inner faces.
  • a fixing device is provided which has a tongue at one end of a screw threaded rod and an adjustable cap at the other, so that the tongue may be inserted and fixed into the dovetail slot and the cap adjusted by screwing on the rod.
  • US patent No. 4,397,065 discloses a reinforcing masonry wall structure comprising a first and a second plurality of courses of masonry blocks to the opposite sides of which first and second layers of plaster-like material are applied. Third and fourth layers of plaster-like material are positioned on the first and second layers respectively. A welded wire fabric material is positioned between each of the first and third and second and fourth layers of plaster-like material. Horizontally disposed reinforcing rods may be extended through the structure to achieve additional bond strength as desired.
  • the technical problem underlying the present invention is therefore that of conceiving and making available a construction element comprising a sectional nog structure which may embedded into one or more foamed plastic slabs, that would be capable of i) being either assembled at the building site immediately before casting concrete, or preassembled at the works and ii) supporting any covering element of the slabs in an extremely flexible way, while allowing to substantially reduce assembling times and labor.

  • 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 preferably made of an appropriate material which does not conduct heat and is preferably fire resistant.

  • 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.

  • the construction element of the present invention allows to advantageously associate on both sides of the formwork or double-slab wall, those covering elements, even of different types, which best meet the construction and/or decorative requirements of the product it is intended to manufacture.
  • the inserts are associated in a removable manner with the respective tierods, furthermore, the further advantages are achieved of a possible access to the concrete casting space, so as to arrange more easily the reinforcing rods, and a possible removal of one of the foamed plastic slabs after hardening of the casting, so as to be able to work directly on the concrete wall and apply thereto the desired covering and finishing layers.
  • thermoacoustic insulation In both cases, the presence of plastic inserts, notoriously a good thermal insulating material, allows to eliminate in a substantially complete manner the development of thermal bridges between the inside and the outside of each slab, contributing to impart optimal characteristics of thermoacoustic insulation to the construction element as a whole.
