Definitions

  • the present invention has for object a process for the installation of concrete manufactured products, particularly with throwaway insulating panels.
  • the invention finds particular even if not exclusive application in the building field and in the production and marketing of technological components for the realization of insulating, both thermally and acoustically, manufactured products in reinforced concrete.
  • the installation of the containing structure known as formwork, for the next concrete casting, requires the execution of at least one wall perpendicular with respect to the ground, generally by using some wooden boards, such as for instance in the realization of a support wall, needing two facing walls, whose interspace, found between these same ones is almost equal to the thickness of the wall which must be obtained.
  • the boards or alternatively the panels are placed coplanar one adjacent to the other and horizontally, supported by an vertical frame, generally made up of series of equidistant support uprights, very often also in wood, up to obtaining a kind of wall, to which corresponds, as explained, facing, the coplanar surface of an analogue wall.
  • an vertical frame generally made up of series of equidistant support uprights, very often also in wood, up to obtaining a kind of wall, to which corresponds, as explained, facing, the coplanar surface of an analogue wall.
  • a second teaching as a logical evolution of the first one derives from a most recent solution, and it is originated from the negative characteristics related to the use, for the construction of civil and industrial buildings, only of concrete.
  • said proposal is embodied in that it obtains finished manufactured products, provided with soundproof and insulating characteristics. More in detail, it aims at using prefabricated panels of pseudo-wooden material in thickened fibre and pressed, to be combined with a covering function, on the surfaces of the manufactured product when it is slightly hard or only after having removed the traditional formwork consisting of wooden boards.
  • the manufactured product furthermore, being obtained by means of the combination of a particular throwaway panel provided with insulating characteristics, both thermic and acoustic ones, allows to answer perfectly to the quality needs required, resulting also suitable for the relative regulations.
  • the panel with the net results considerably more reliable and resistant, in the particular case, when used as a formwork leaving it inserted in the concrete, which allows to ensure an increase of the bending resistance, furthermore allowing, a considerable increase of the bearing capacity of the elastic module and of the adhesion strength with optimum results.
  • Figure 1 shows a perspective view of a semi-finished panel for a formwork obtained in wooden fibre and of a respective net to be associated in correspondence of at least one surface.
  • Figure 2. shows again a perspective view of a panel, this time a finished one, for the realization of a throwaway formwork.
  • Figure 3. shows a scheme for the application of throwaway structural panels, among which appears a part of the concrete manufactured product which covers them.
  • Figure 4. shows a cross-sectional view shown in the previous figure and which comprises said particular panels of the throwaway formwork.
  • Figure 5. shows a plan view of an element which makes up a spacing means.
  • Figure 6. shows a front view of a ring as a locking key for the interaction with the spacer in Figure 5.
  • Figure 7. shows a perspective view of a one end and of the group of a spacer shown in Figures 5. and 6., particularly for the realization of a throwaway formwork.
  • Figure 8. shows a side view of a throwaway formwork made up of more panels of the type shown in Figure 2., for the realisation of a reinforced concrete manufactured product.
  • Said throwaway formwork (A) is essentially made up of a series of particular structural panels (1) placed, in the particular case, perpendicular to the ground (s), with a preferably rectangular shape and which are installed according to a known art, one adjacent to the other, held in their upright position by a series of supporting uprights (2), preferably equidistant.
  • a second wall for example in case of realization of a concrete wall, is similarly obtained in specular manner respect to the previous one, and held at a certain distance from the first one by using suitable spacers (3), also of the throwaway type, placed transversally respect to the two formwork retaining walls (A).
  • Each structural panel (1) used in the realisation of the formwork retaining walls (A), is of the type obtained in mineralized wooden fibre.
  • it is a product obtained from the working of a mix of wooden fibres, such as pine tree, to which are added some mineral bonding (mainly cement) for then being pressed and formed.
  • a net (1'') with thick meshes of the fiberglass type.
  • the process for the joining of the net (1'') to the surface (4) of a panel (1') is extremely delicate because it must avoid the clogging of the cavities of the underlying panel (1').
  • a structural panel (1) it is provided the use of a micro-holed thermoplastic film, to be place between the surface (4) of the panel (1') and the fiberglass net (1''). Said film, heated at temperature > 150°C, substantially melts and holds said net (1''), mainly in correspondence of the fibre, as consequence leaving the meshes of the same in direct connection with the underlying surface (4) of the panel (1'), without clogging the cavities found in the uneven distribution of the wooden fibres.
  • the structural panel (1) is simply let cool in the air up to completing the cycle, for then being stacked and sent to the building site for its specifical use.
  • the spacing means (3) For what concerns the spacing means (3), also they buried in the manufactured product (B), they essentially consist of a metal plate, having a certain thickness, provided, in proximity of its ends, with slots (6) and with a series of reference notches (7), in the particular case three of them correspond specularly to each end side.
  • some rings (8) for example obtained in plastic material as nylon, centrally provided with a hole (8') which is the engagement key ins standard positions. Said key is obtained by removing, along the circumference of the internal hole (8'), two portions (9) diametrically opposite, whose distance between the same corresponds to the metal plate coaxial width, allowing the insertion and the longitudinal constrained sliding.
  • the hole diameter (8') corresponds to the distance between centers found between two opposite notches (7).
