Definitions

  • the present invention relates to a plaster-based construction element, for making ceilings or vertical elements, lining walls, and in general for covering any building structure.
  • the reinforcement by a simple sheet of wires embedded in the plaster is not sufficient for construction elements which must have their own rigidity and have a high resistance, in particular to impact.
  • the use in the form of panels folded up relative to one another is not systematic and a flat use can be envisaged, and therefore the grooves are only made, if they are necessary, at the time of use, or when said grooves are made other than by molding, there is a risk of damaging all or part of the reinforcements embedded in the plaster.
  • the present invention aims to remedy the drawbacks of the products of the prior art.
  • the present invention provides building elements made of plates or tape, in particular plaster, comprising reinforcements distributed over most of their thickness, in which the reinforcements are concentrated in a determined zone of thickness, along parallel lines. on the faces of the plates, while everywhere else, they continue to occupy most of the thickness.
  • these lines will be parallel.
  • the plaster is eliminated directly above these lines where the reinforcements are concentrated, thus constituting a plurality of panels joined by reinforcements and foldable with respect to each other.
  • the construction elements will have two fold lines delimiting three panels, the two side panels being of smaller dimension than the central panel, so as to form after folding a tray with two flanges, the height of the flanges being of the order of 1/40 th of the length of the building element and the two flanges being folded over on the same side of the plane of the central panel.
  • these construction elements will be filled with insulation of the mineral wool or foam type.
  • a ribbon or a plate is formed by pouring a liquid mixture of plaster and water and reinforcements are introduced which may occupy most of the thickness of the ribbon or plate, and the reinforcements are concentrated by lifting and / or compression inside the strip or the plate along lines parallel to the direction of travel of the casting hearth, until the concentrated position of the reinforcements along these lines can be kept alone.
  • the concentration action is exercised before the plaster has reached a consistency which corresponds to the FLS fluidity equal to 100 and this action is maintained until the plaster has the FLS fluidity close to 60.
  • the invention also provides devices for manufacturing these construction elements.
  • the device comprising a bottomless pouring tank placed on a pouring floor provided with flanges, running at uniform speed, a pouring slot adjacent to the pouring floor under the front wall of the tank, means for introduction of the reinforcements, has in addition ribs in relief on the casting hearth along the lines where it is desired to concentrate the reinforcements, parallel to the direction of travel of said casting hearth, at least over a length after the casting slot, equal to the distance which the cast plaster travels before having reached the consistency which corresponds to the FLS fluidity close to 60.
  • the device comprising a bottomless pouring tank, placed on a pouring floor provided with edges, running at uniform speed, a pouring slot adjacent to the pouring floor under the front wall of the tank, means for introducing the reinforcements, furthermore has means of the profile or disc type for driving in the reinforcements, arranged above the casting hearth, directly above the lines where the reinforcements are to be concentrated, at such a level that their lowest portions are located below the upper surface of the building elements, at a distance from said surface equal to that to which the reinforcements are to be inserted, said insertion means being at least arranged in the zone or the plaster has its consistency which varies between FLS 100 and FLS 60.
  • Fig. 1 shows a building element according to the invention, consisting of a tape or a plasterboard 1, reinforced at least in its mass by glass son 2 visible on the edge of the tape or the plate.
  • the glass strands 2 are concentrated in determined zones of thickness, while everywhere else they are distributed in practically the entire thickness of the ribbon or plate.
  • the glass strands are concentrated along these lines until they form only a plane reduced to the thickness of said strands.
  • Fig. 2 shows a building element obtained from the building element of FIG. 1.
  • the ribbon or the plasterboard 1 reinforced at least in its mass by glass strands 2, said glass strands being concentrated in determined zones of thickness, along certain lines parallel to the faces of the plate.
  • the plaster is removed.
  • the plate 1 has lines, in this case in FIG. 2 lines 3a and 3b, comprising only reinforcing wires 2, said lines delimiting panels or shutters 4a, 4b, 4c ... articulated with respect to each other by folding around the hinges that constitute lines 3a, 3b.
  • FIGS. 1 and 2 are for example reinforced by a plurality of glass reinforcements, said elements being shown in exploded view in FIG. 3.
  • a sheet of continuous, looped and entangled glass threads 2a enclosed above and below by a grid of glass threads 2b and 2c preventing excessive swelling of the threads of the sheet 2a in the thickness of the product, and preventing loops from protruding from the faces of the product or from being visible on said faces.
  • the plaster is absent and that only the reinforcements are visible, in particular the upper grid 2b.
  • Other reinforcements 2 can be used: textile threads, natural or synthetic, at least some of which are arranged in a direction such that the connection between two flaps such as 4a and 4b is ensured, independent metallic threads or in layers, veils of glass, gratings alone, for example of glass strands, woven fabrics, nonwovens, plies of continuous glass strands identical to ply 2a alone, organic or mineral fibers, thus for example of glass, cut, to provided however that at least some are arranged transversely to the fold lines and that they have a length such that they can ensure the connection between two flaps, that is to say at least a length of 5 to 6 cm for plaster tapes, approximately 6 mm thick.
  • the fold lines such as 3a, 3b may be parallel as shown in fig. 2, but they may also not be parallel when it is desired to produce by bending conduits or sheaths, for example in the form of a pyramid trunk.
  • the plane which contains the reinforcements 2 along the fold lines is a median plane parallel to the faces of the plaster tape 1, substantially at mid-thickness of the said tape.
  • the level of this plane in the thickness of the ribbon may be different.
  • This plane containing fold lines may be close to one face of the ribbon, be on one side or be located at any other level in the thickness of said ribbon.
  • the width of the fold line, free of plaster, will depend on the thickness of the tape 1, the height of the plane containing the fold lines in the thickness of the ribbon, the direction of folding of the flaps relative to each other, and the angle of folding.
  • a plaster tape 1 such as that shown in fig. 2, reinforced in its thickness with fold lines free of plaster, consisting only of reinforcement 2 brought in a single plane along these lines can be folded in accordion to form the building element shown in fig.4, usable for example to make decorative partitions or ceilings with several shutters 4a, 4b, 4c, ... 4i ...
  • the same ribbon 1 can be folded as shown in fig. 5 to form sheaths or conduits, for example sheaths to surround metallic structures and protect them from fire, an insulator then being inserted between metallic structure and plaster sheath, for example air ducts. Since the ribbon 1 with several flaps has received its form of implementation, accordion or other, it can be blocked in this form by making the two edge portions of the two flaps which adhere to the folding suite. These two slice portions can be made to adhere to one another with plaster brought back inside the fold, or with a hot-melt adhesive.
  • each fold line belonging on the one hand to a flange 11 or 12 and on the other hand to the main flap will have substantially an open V-shaped profile with an angle close to 120 °.
  • These edges 11 and 12 will be raised relative to the main flap by an angle of approximately 90 ° to form a U-shaped container. In any event, this angle will depend on the use that one wishes to make of these containers. In some cases that we will consider later, the edges will be raised by an angle slightly greater than 90 °, or about 95 °, so as to form a U-shaped container with tight edges; in other cases, on the contrary, they will be raised by a lesser angle, of the order of 85 °, so as to form a slightly open U-shaped container.
  • the level of the fold lines 13 and 14 in the thickness of the plates will depend on the use that one wishes to make of the trays.
  • the folding can be done around the hinges 13 and 14 located as shown in fig.7A, at the upper face of the plates 1; the edges 15 and 16 of the tray then have a staircase profile, and a reinforcement or a surplus of glue or plaster forming a bead 17, 18 inside the folds along the hinges 13 and 14 is then necessary to keep the edges raised.
  • Folding can be done around hinges 13 and 14 located as shown in fig. 7B at the level of the lower face of the plates 1; the edges 15 and 16 at the bottom then have a clean square profile.
  • Each fold along the hinges 13 and 14 then shows two bevels 19 and 20 of maximum length, which can be glued one on the other. Folding can also be done around hinges 13, 14 located as shown in fig. 7C at any level in the thickness of the plates.
  • edges 15 and 16 of the tank have a chamfered profile and the bevels 19 and 20 have a length intermediate between the maximum length that they had in the case of FIG. 7B and the zero length in the case of FIG. 7A.
  • the two flanges or wings 11 and 12 will have a height of the order of 1/40 th of the length of the module, that is to say approximately 5 cm for 2 m of length.
  • Plaster or hot melt glue will be brought inside the two plies.
  • This tank thus formed could serve as an insulating support 13, mineral wool or foam of the polystyrene or phenolic foam type, as shown in fig.8.
  • this insulator 13 will be bonded to its edges, to the edges 11 and 12 and possibly will also be bonded over its entire surface to the flap 10.
  • Such a module will have increased rigidity due to the edges and also from the fact that the reinforcement will have remained intact. at the hinge, that it will not be tensioned, that it will not be removed from the plaster.
  • a batch is poured discontinuously or continuously, as described in application FR-A-2 416 777 or in EP-A-0 003 705 which corresponds to it, a liquid mixture of plaster and water with fluidity FLS greater than 120.
  • the FLS test gives an expression of fluidity in mm.
  • This test is a test commonly used by plaster manufacturers and it indicates the behavior of a plaster when it is poured. It consists in filling a hollow cylinder with a diameter of 60 mm and a height of 59 mm, placed vertically in the center of a polished metal or glass plate, with a plaster mixed with water.
  • the cylinder is lifted and the plaster is released which spreads over the plate to form a disc whose diameter is measured.
  • the measurement of this diameter constitutes the fluidity reference F at time t.
  • the mixture is contained in a bottomless casting tank, placed on a casting hearth provided with edges, running at uniform speed, and flows continuously through an adjacent slit, at the casting hearth and disposed under the front wall of said tank. Replacement mixture is continuously introduced into the tank, contrary to the direction of travel of the casting hearth, with enough energy to cause agitation and thus avoid caking without disturbing the casting.
  • a reinforcement is introduced into the liquid mixture, either before casting, especially when working batchwise, or either before, during or after casting as described in application FR-A-2 416 777 or EP-A-0 003 705, already mentioned when working continuously.
  • the panel can be left to dry with only the concentrated reinforcement along certain lines, without releasing the plaster directly above these lines, this clearance being effected so then when the panel is dry, for example at the time of use, without risk of damaging the reinforcement, because it is well concentrated in one plane and no longer abounds throughout the thickness.
  • the casting hearth can be provided at the location of the fold lines of ribs that move with it.
  • the pouring floor 21 is movable and on it is placed a bottomless tank 22, formed by two plates, a downstream plate 23 and an upstream plate 24 and flanges 25, 26 of the casting sole, made of rubber, which moves at the same speed as the casting hearth coming to bear on the lateral ends of the downstream and upstream plates.
  • This tank is provided with a pouring slot 27 under the downstream plate 23 and it is continuously supplied by horizontal jets 28 of liquid plaster and water mixture, jets which ensure stirring of the mixture contained in the tank and which avoid its solidification.
  • the reinforcement 2 in the form of a sheet of glass strands and / or grids of glass strands is for example introduced under the pouring tank, and it is thus trapped in the layer of poured mixture and entrained on the sole of casting with said layer.
  • the casting hearth being provided with projecting ribs 29, the reinforcement is raised by these ribs, directly above these ribs, while everywhere else it retains its position.
  • the fold lines are to be located substantially at mid-thickness in the plasterboard, perpendicular to the ribs, above the plaster tape, there are a plurality of discs 30 which drive the reinforcement.
  • discs 30 as shown in detail in fig. 10 will be rotating, for example in "lucoflex” or in p.v.c., 150 mm in diameter and 3 mm thick and with an edge making an angle of 120 °.
  • disks 35 identical to disks 30.
  • the discs 30 and the discs 35 when they act before the end of setting of the plaster around the fluidity FLS 60, create, on each side of the fold lines, beads of material which, when the edges are folded, will increase the length of the bevels 19 and 20 (fig 7B) in contact.
  • pvc profiles or lucoflex flat as long as they are upstream of the casting tank or under the said tank, then gradually transforming, to take a triangle section, for example equilateral, with a length of 1.50 m downstream from the pouring from a height in their triangle section portion of 2 to 3.5 mm when it is desired to manufacture plasterboard 6 mm thick may be suitable.
  • disengagement disks can be used to disengage the plaster above the lines where the reinforcement has been concentrated.
  • these construction modules in the form of a tank, with or without an insulator can be used to make ceilings. Because of their resistance to bending, they can have long spans, greater than 2.50 m and two modules placed end to end can make the width of practically all the parts. To put them in place between two purlins of the roof or between two beams, the two ends of the tanks are supported on a cleat or a profile fixed along each purlin or each beam.
  • the tanks to be used are preferably tanks for which the edges 15 and 16 shown in figs 7 will be chamfered (fig. 7C) or will have a stepped profile (fig. 7A ).
  • tanks will preferably be chosen whose edges have only been raised by an angle of less than 90 °, that is to say 85 °, so as to have an open U shape.
  • tubs with a sharp angled edge as shown in FIG. 7B.
  • Such tanks can also be assembled to form sheaths or conduits.
  • containers according to the invention is also possible with other materials other than plaster, for example cement.
  • the reinforcement or “the reinforcements” used in this description are used interchangeably whether there is a single reinforcement or that there are several partners.
