Definitions

  • This invention relates to a re-usable column shuttering, said columns being made for example, from reinforced concrete, and where the shuttering is of the type which features a tubular shape produced from a plurality of sections of polystyrene suitably joined together at their edges in order to conform the tubular shape which corresponds to the shuttering itself.
  • the object of the invention is to provide a shuttering, in which the polystyrene sections are attached to an unfolded sheet of suitable material, such as thermoformed plastic, stool profile, etc. thus allowing a reduction in volume in both the storage and the transport of tho shuttering this being closed at the workface.
  • the corresponding machine with which the shuttering is produced or prepared is also an object of this invention.
  • the shuttering is based on the use of elements with a cylindrical section shape which, when correctly assembled give rise to a cylindrical external surface and a prismatic internal surface, or with the appropriate shape, according to the characteristics of the column to be produced; in all those cases the common denominator being the fact that the shuttering leaves the factory in a finished state, that is, having a tubular shape which indubitably occupies a largo amount of space, with the corresponding storage and transport problems, and of course with the increase in costs which is due to this considerable volume
  • the re-usable shuttering announced has been conceived in order to solve the problems outlined above, on the basis of a simple but highly efficient solution, based on the fact that the polystyrene sections which will make up the tubular body of the shuttering are fixed by adhesive to an internal sheet which may be made of thermoformed plastic, galvanised or stainless steel profile, etc, which will incorporate the necessary longitudinal score lines in order to form the edges or folding lines when the assembly of the sheet and the polystyrene sections are to be closed in order to produce the corresponding tubular shuttering, with the special feature that in the event of producing a cylindrical shuttering, the score lines which define the aforementioned folds are not required.
  • the internal shoot features, at regular intervals, corresponding to the width of the polystyrene sections, a number of bends for the adjustment of the shapes which establish the collateral joints of the polystyrene sections; it is at these bends that the scored (weakened) lines for the centring of the shuttering appear.
  • the internal sheet, to which the polystyrene sections are affixed by adhesive make up a single, flat assembly or body, which may be easily stored or transported, taking up a much smaller space than the shuttering when closed, that is with the tubular body formed, due to the considerable reduction in dead space
  • Each shuttering, in assembly, will be closed at the workface in order to transform the flat body into a tubular body, closure being carried out by means of a self-adhesive strip made up of a paper or similar backing incorporating glass-fibre strands in order to resist the pressure of the wet concrete when this is poured into the tubular body of the shuttering, with the special feature that this self-adhesive strip is applied externally to the tubular body -thanks to a layer of self-adhesive glue incorporated in the same- by means of an appropriate machine.
  • the shuttering is thus ready for use, and once used, the shuttering is cut open along the edge of the seal, which will he duly marked, it then being cleaned, the self-adhesive strip removed, the shuttering being closed again by means of another new self-adhesive strip and thus being ready for subsequent use.
  • the machine for the preparation of the shuttering disclosed is comprised of a supporting framework on which an upper spindle is arranged; the turning motion of this spindle being driven by a motor; said spindle is complemented by a pair of side-mounted wheels at some distance from the same in order to serve as a point of support for the tubular polystyrene body, in such a way that the rotation of the motor causes rotation of the spindle and therefore of the tubular body, in order to allow the application by winding of the self-adhesive strip.
  • the operation of the tubular body may be carried out manually in which case the motor would e eliminated, and the aforementioned spindle would be replaced by a pair of wheels set on the same lateral plane as the other two end wheels.
  • the shuttering of this invention is comprised of a ractangular-shaped internal sheel (1), which may be made of plastic, steel or other suitable material, on which polystyrene sections (2) are affixed by adhesive, forming a flat body as portrayed in Figure 1, which is the unfolded view of the body of the shuttering to be produced by means of the closure of said body portrayed in said figure 1; closing the same by its free edges the tubular body (3) is produced, which forms the shuttering in itself which, in tho embodiment portrayed has a cylindrical external shape and a prismatic internal surface, without ruling out the possibility that it may also be cylindrical internally,
  • the internal shoot (1) will feature a series of weakened bending lines (1') in order to allow bending along the same to form the tubular body (3) with a rectangular prismatic shape, as portrayed in figure 2.
  • the weakened lines (1') correspond to the edges of the respective folds (5) with which the sheet (1) is provided, the distance between these corresponding to the width of the polystyrene sections (2) these being joined together forming shapes (6) which, on folding or closing, adjust to the shape of the bends (5) in the sheet (1).
  • a means of marking is applied, by which the subsequent opening of the shuttering will ho carried out, by cutting along the line of the joint, allowing the use of the shuttering.
  • closure of the tubular body (3) in order to withstand the pressure exerted outwards by the concrete which is to be housed within the body (3') of the same in order to form the corresponding column, is carried out by means of the external application of a self-adhesive strip which may be wound helically, with the special feature that this strip may be made of a paper or similar backing with a layer of self-adhesive glue on one of its sides, and glass-fibre strands may be embedded in the heart of the same, in order to withstand the pressure exerted by the wet cement when this is poured into the space (3') of the tubular body (3) of the shuttering.
  • a machine (7) For re-use of the shuttering, a machine (7) should be used, by means of which a layer of film wrap, which will allow the removal of the self-adhesive strip for each re-use, will be applied. It is also with this same machine that the self-adhesive strip, for re-closing the shuttering, is applied.
  • the machine (7) is formed by a framework or bedplate on which an upper horizontal spindle (9) is arranged, the tubular body (3) of the shuttering rests between this and a pair of end wheels (10) set at some distance from said spindle.
  • the machine incorporates a motor (11) which drives the spindle (9) in such a way that the rotation of the latter causes rotation of the tubular body (3), allowing the application by winding of the self-adhesive strip.
