Definitions

  • the present invention relates to a formwork for the production of a wall having a central cavity intended to receive in particular an insulating material and which comprises recoverable external formwork elements forming two panels arranged in parallel and held together by liaison bodies.
  • Formwork comprising recoverable external panels are well known and widely used in practice.
  • the internal shuttering elements forming the panels delimiting said cavity can only be recovered by using complicated and costly removable shuttering systems. .
  • this embodiment has the major disadvantage that, under the pressure of the poured concrete, the projections, even rounded, which are arranged discontinuously along the spreader bars, sink into the boards of the internal formwork, which practically prevents any subsequent rotation. bars. Formwork removal is therefore not possible.
  • the object of this invention therefore consists in providing a formwork for the realization of a wall having a middle cavity and whose internal formwork panels are easily recoverable after the completion of the wall, which does not have the drawbacks of known formwork, in particular according to the aforementioned French patent.
  • the formwork, object of this invention which is characterized by the fact that it comprises internal formwork elements disposed between the external panels to delimit said cavity, by the fact that the internal elements are kept at a distance from them. from each other by locking members, these members being in contact with said internal elements over their entire length, and applying these elements against stops integral with the external panels, and by the fact that these locking members allow release by rotation according to their longitudinal axis of the internal formwork elements so that they can be recovered after the completion of the wall.
  • the first embodiment of the formwork according to the invention illustrated in Figures 1 to 4 comprises two external formwork panels 1, the formed of elements 2, preferably of wood, assembled longitudinally, these panels 1, 1 'being arranged in parallel and conventionally held to one another by connecting members formed by a clamping rod 3 with external nuts 4, 4 'and a spacer 5, generally made of plastic, with adjusting devices 6, 6 'of the length of these connecting members.
  • the slats 7, 7 ′ integral with the external panels 1, l ′ of the formwork are intended to serve as stops against which the internal formwork elements 11, 11 ′ come to bear.
  • These internal shuttering elements delimit a central cavity 12 and are applied against the slats 7, 7 ′, in the service position, by locking members 13.
  • These locking members 13 consist of elongated elements whose cross section is such that it has at least two different diametrical dimensions, the most large diametrical dimension corresponding to the desired width of the central cavity 12.
  • these locking members can be constituted by two pipes welded to each other longitudinally.
  • the locking members 13 in their locked operating position are supported over their entire length. against the internal formwork elements 11, 11 'and apply these against the slats 7, 7'.
  • the locking member 13 in its locked operating position shown on the upper part of the drawing tends to apply the internal shuttering elements 11a, 11'a against the slats 7, 7 ', while in the unlocked position mounted on the lower part of this drawing, the locking member 13 ′ has been placed by rotation around its longitudinal axis by a quarter turn so that its largest diametrical dimension in section is then parallel to the elements of internal formwork llb, ll'b and that these are no longer held against the slats 7, 7 '.
  • the locking members 13 are provided at their end with a U-shaped element 14 intended to receive a bar 15 of square or circular section serving to simultaneously lock all the locking members 13 in their operating position.
  • a washer 16 is welded between the upper end of the tubes constituting each locking member 13 and the U-shaped part 14. This washer 16 extends beyond the largest dimension in section of the locking member 13 and is intended to bear on the upper end of the internal formwork elements 11, 11 '. This keeps the locking members 13 all at the same height, even if they are not all of the same length, and prevents them from falling to the bottom of the internal formwork if they are lower than that -this, for example as illustrated in FIG. 2. Similarly, all the parts in U 14 are at the same height, and the establishment of the bar 15 simultaneously locking in the service position all the locking members 13 is thereby facilitated.
  • connection members of the external formwork panels and / or the fixing members reinforcing the slats forming abutments with the internal formwork elements can also be used for fixing lattices 17, 17 ′ intended to reinforce the concrete forming the wall.
  • the internal formwork elements 11, 11 ' are introduced between the external panels 1, the and applied against the abutment slats 7, 7' by the locking members 13 placed in the service position, that is to say say with their greatest diametrical dimension in section perpendicular to the internal elements 11, 11 'and with their washer 16 bearing on the upper end of these elements.
  • the locking members 13 are locked in this operating position by means of the bar 15 cooperating with the U-shaped elements 14 with which the ends of the locking members 13 are provided.
  • the concrete can be poured into the spaces provided between the external panels 1, the and the internal elements 11, 11 ′.
  • the locking bar 15 is removed and the locking members 13 are placed in their unlocked position by rotation thereof, one after the other, along their longitudinal axis, so as to place the largest diametrical dimension in section parallel to the internal shuttering elements 11, 11 '.
  • the central cavity 12 formed inside the wall is thus ready to receive the desired material, for example an insulation material such as polyurethane foam.
  • the external panels 1, l ' are recoverable as are the clamping rods 3 and the nuts 4, 4', the other elements of the formwork (spacers, slats-stops, etc.) being them lost.
  • the device intended to serve as a stop for the internal formwork elements 11, 11 ' is mounted in advance in the form of a support element 18 ready for use and replacing the slats 7, 7', the spacer 5, 9, and the reinforcement rods 10 of the first form of execution.
  • Each support element 18 comprises two slats 19, 19 'fixed parallel to each other at a distance determined according to the desired width of the central cavity 12 by means of small boards 20 arranged transversely between the slats 19, 19' .
  • Transverse holes are further drilled in the slats 19, 19 ', their number depending on the total length thereof, and sleeves 21, 21' of variable length thanks to a stop 22, 22 'screwed to the end of each sleeve, are fixed transversely and directed outwards in correspondence with each orifice.
  • the slats 19, 19 'and the transverse boards 20 are made of wood and the sleeves 21, 21' of plastic.
  • Another advantage of this second embodiment compared to the first, apart from the ease and speed of assembly, is that once the fixing rods 13 removed to recover the internal elements 11, 11 'and the external panels 1, the formwork, the insulating material introduced into the formed central cavity 12 also fills the space left free by said rods 23, while in the first embodiment described (see Figure 1), the spacers 5, 9 remaining between the slats 7, 7 ′ after the withdrawal of the clamping rods 3 respectively of fixing 8 tend to form inside the insulation non-insulated passages connecting the two outer and inner portions respectively of the obtained wall thus reducing the efficiency of its insulation.
  • the second embodiment of the formwork according to the invention is further distinguished. in that the outer formwork panels 1 forming the inner wall of the wall are shorter than the outer formwork panels forming it the outer wall of the wall. It is thus possible to construct a wall as illustrated in FIG. 6 having an inner wall 25 shorter than the outer wall 26, this in order to allow the pouring of a slab 27 resting on the upper edge of the inner wall 25 shorter of the wall. Thus, after the formation of the intermediate layer of insulating material 28, the slab 27 is itself perfectly isolated from the outside.
  • an accessory 29 intended to be placed in the service position (see FIG. 5) on the upper edges of the external panels 1, l 'in order to serve as a funnel for pouring concrete simultaneously for the formation of the inner wall 25 and the outer wall 26 of the wall.
  • This funnel 29 comprises two flow chambers 30, 31 having at their lower end an elongated opening and separated from each other by a wall 32 in the form of an inverted U; each flow chamber 30, 31 being intended to supply the interior of the formwork with concrete for the simultaneous formation respectively of the interior wall 25 and the exterior wall 26 of the wall, one 31 of the two chambers is shorter than the other 30.
  • Supports 33 are further fixed horizontally near the lower open end of each flow and are directed outward so that they can rest on the upper edge of the external formwork panels 1, l ' .
  • the formwork according to the invention therefore makes it possible to produce a wall having a central cavity intended to receive an insulating material for example, and to recover after the completion of this wall not only the external formwork panels, but also and easily the elements of internal formwork, which makes its use particularly advantageous, the recovery of internal formwork elements not being possible with known formwork, even with that described by patent FR 534.688 for the reasons already mentioned.
  • the locking members are in contact over their entire length with the internal shuttering elements, which prevents them from sinking into them and thus allows easy rotation around of their longitudinal axis when one wishes to proceed with the formwork and the recovery of these internal formwork elements.
