Definitions

  • the general principle is as follows: two vertical forms are kept apart by a system of tie rods, which is subsequently embedded in the filling material constituting the wall; the two forms when they are each made of insulating materials allow to realize the internal and external insulation of the wall; of course, depending on the case, the two forms may not be insulating if the need for insulation does not exist, or even only one of the two internal or external forms may be insulating depending on whether the insulation is necessary respectively for the indoors or outdoors.
  • the forms are made of kinds of large hollow bricks whose side walls are insulating or not, or even insulating on one side and non-insulating on the other; in fact, the bricks are fitted vertically into each other, and the wall material is poured into the hollow parts of the bricks.
  • the inventor has not proposed specific means to facilitate the continuous pouring of a wall between two walls held together by lost formwork elements.
  • the second is that the use of common concrete (the most frequent) in the device according to PATURLE, favors the swelling of the formwork, and very often its bursting.
  • each of the parts constituting the spacers require a specific dimension, which makes it necessary to manufacture expensive sets of complete molds.
  • the invention provides a device for assembling formwork (2) fig. 2 used in lost formwork and imagined mainly as a function of its capacity to allow continuous filling, as easy as it is complete, of the space between the forms, these being composed, in the widest application of the invention, high density expanded polystyrene insulating building materials or other special hard foams, or non-insulating materials.
  • These forms are thick rectangular panels, preferably flat stackable on edge.
  • This device consists essentially of vertical U's (1) fig.1 equal, arranged consecutively to each other at regular spaces, and whose slides (a) fig.1 wings, perpendicular to the planes of the U, trapped in opposite grooves against undercut (3) fig.2 provided vertically in the thickness of the forms on their internal faces, are clipped symmetrically on horizontal honeycomb inserts (6) fig.3 integrated at mid-thickness in the edge upper horizontal (4) fig.2 of the underlying panel, and in the same action in the lower horizontal edge (5) fig.2 of the overlying panel thanks to the arrangement on each penetrated edge, of grooves (7) Fig. 2, female imprints of the penetrating section of the insert, so that the insert (6) once put in place, is completely trapped between the edges (4) and (5) kept contiguous and secured.
  • the slides (a) of the wings of the same U (1) penetrate vertically after sliding in the above-mentioned undercut grooves (3) of the forms, so that these are kept in constant spacing and materialize between them a volume to be filled for the purpose of building a monolithic wall by continuous casting.
  • the consecutive horizontal alveoal inserts (6) connecting between two forms are standards of the same length, which can be cut if necessary, and which consist in their most practical configuration, of two long vertical flats (8) fig .3 of length (L) kept parallel to each other by short vertical flats also (9) fig.
  • the symmetrical housings (17) and (17 ') consist of two preferably identical compartments (11) and (12) fig. 3 for (17) and (11') and (12 ') fig. 3 for (17 '); the housings (17) and (17 ') are located one (17) at the upper edge and the other (17') at the lower edge of the internal lateral face of the insert (6) so that the height (h) of each housing preferably corresponds to one third of the total height (H) of the lateral face of the insert.
  • the two symmetrical compartments (11) and (11 ') (respective housings (17) and (17')) situated against the wall of the insert (6) are intended, for the compartment (11 ') to be received by clipping the upper part of the slide (a) of the wing of a U (1) previously incorporated by vertical sliding in the undercut groove (3) fig. 2 of the underlying panel, and for the compartment (11) to receive by clipping the lower part of the slide (a) of the wing of a U previously incorporated by sliding in the undercut groove (in alignment of the first) of the overhanging branch.
  • Both are clipped by means of a set of two vertical spring hooks (10) fig.1 arranged back to back vertically at each end of the slide (a) of the wing of a U ; these hooks are designed to resemble each other elastically by manual pressure exerted to make them penetrate the vertical compartments (11) and (11 '), and at the end of the stroke, relax horizontally to return to the position initial and clip symmetrically on the edges (16) fig.4 opposite compartments.
  • These two spring hooks (10) and the compartments (11) and (11 ') in which they are then incorporated constitute a stable integral assembly, insofar as the thickness of the hooks corresponds by slight defect to the width of the compartments ( 11) and (11 ').
  • the U (1) in a vertical position, located in a perpendicular plane between the two forms in which they are incorporated in symmetrical undercut grooves (3), are secured to these forms thanks to the compartments (11) and ( 11 ') of the internal face of these, along the inserts (6) consecutive arranged horizontally and embedded at mid-height in the edges in contact with these two consecutive vertical forms.
  • the wings of U (1) fixed in the undercut grooves (3) of the forms and clipped into the vertical lateral housings (17) and (17 ') of the inserts (6) locking two successive forms by their horizontal edges (4) and (5) in contact make it possible to obtain a solid assembly, in order to flow continuously between the forms any originally fluid material (or practically), specifically intended for the construction of a wall, knowing that only will be embedded in the casting, as lost formwork elements, the volumes corresponding to the bases (14) fig.
  • the bracing can be improved by nesting the ends (19) and (19 ') fig. 1 of the vertical parts of the wings of U, perpendicular to the forms and remaining outside these forms, (these ends (19) and (19 ') can moreover be arranged in reduction of section (r)), in cavities (20) and (20 ') fig. 1 of the same volume by slight excess as these ends and provided symmetrically perpendicular to these in the thickness of the edge of the base (14) of the U.
  • the formwork before pouring, in addition to the fact that its internal elements represent a negligible volume between the forms, constitutes a set of undeniable rigidity and robustness by the fact that its structure as much longitudinal (along the inserts) that vertical (in the plane of the U) has all the attributes necessary for a perfect connection and overall compactness, while avoiding all of the drawbacks listed in the analysis of the PATURLE patent, presenting a technique from which we now deduce that it is very distant and much less efficient than that proposed by the invention.
  • the entire device presented in the invention allows very high forms (practically up to the height of a storey), provided that the U and the inserts used are of sufficient robustness, which is technically feasible insofar as it is as much for the U as for the inserts, parts generally injected from originally hard materials, the rigidity resulting therefrom being able to be further optimized by the conformation of said parts as well as by various appropriate ribs.
  • the device could very well use U in the base of construction (at the level of the floors) for a better seat, then H vertically nested in the U.
  • an indexable angulator (21) consisting, as shown in Figures 5 and 6, of two preferably equal plates (x) and (y) secured in vertical hinge (v), each of the plates vertically integrating at its end an element (z) identical in all points to the wing portion of U comprising the slide (a), the two clipping systems each consisting of two vertical spring hooks (10) arranged back to back vertically at each end of the slide (a) and the bar (13) in the form of a flat parallelepiped secured to the upper part of the wing.
  • the angulator can then be indexed to materialize, by the adequate opening of the hinge (v), the desired internal angle at the vertical junction of two formwork after the two elements (z) of the angulator have been placed in the undercut grooves and the inserts of each of the two forms, one of the forms and its integrated insert having been previously sawn vertically at a cutting angle equivalent to the angle which is to be obtained at the junction of said formwork.
  • the angulation of a wall implies the internal angulation of the two external formwork of the wall and the equivalent internal angulation of the two internal formwork of the wall, constituting the lost formwork of said wall.
