Definitions

  • the present invention relates to a device for producing gable walls, that is to say facade walls poured at the end of a building in constructions made of concrete, this realization necessitating the use of special means for holding formwork and movement of people.
  • the current technique for implementing these means requires four successive interventions, namely: - poses crows intended to support the consoles; - installation of consoles; - installation of forms on these consoles; - adjustment of the external stabilizers of said formwork; which requires a relatively long installation time.
  • An object of the present invention is to remedy these drawbacks.
  • a formwork device or scaffolding comprising a metal frame comprising external uprights, the upper part of which is rigidly connected, by means of horizontal crosspieces, to the upper part of internal crutches with adjustable length.
  • a formwork comprising a rigidly fixed panel or intended to be rigidly fixed against the internal face of said external uprights, and a movable panel suspended from horizontal crosspieces with the ability to roll or slide along them; the uprights having a greater length than that of the crutches and extending below the lower edge of the fixed panel, the part of said uprights which extends below the lower edge of said fixed panel being provided with a shoe allowing the support of the latter on shoes fixed on a portion of wall previously made, this part being able to carry, in the vicinity of its lower end, the framework of a leveling bridge.
  • This construction provides several advantages.
  • the invention also relates to an adjustable support device making it possible to establish a stable and secure connection between the uprights of the framework of the formwork scaffolding and the support members fixed to the portion of wall already made.
  • This device includes: - on the one hand, support pads integral with the uprights of the frame and each comprising a small arm arranged perpendicular to the upright which carries it and rigidly integral with the latter, the free end of this arm being provided with two opposite lateral branches oriented perpendicular to said arm which carries a fixed nut into which a threaded wedging rod disposed parallel to the arm and part of which crosses the upright; the external end of this rod being arranged to allow it to drive in rotation, while its internal end is equipped or shaped to have a bearing surface, and, - On the other hand, support shoes for supporting these support shoes and each comprising a flat bottom wall which can be provided with a hole for the passage of the rod of a fixing member , a support plate arranged perpendicular to this wall, two opposite side walls arranged perpendicular to said bottom wall and to said support plate and having aligned holes for the passage of the rod of a locking member, and two spaced guide ramps placed in front of the support plate and inclined towards the upper
  • This device allows easy, quick and secure fixing of the frames to the load-bearing walls, using any suitable lifting equipment, and, just as easy and quick removal of said frames.
  • the device for producing pinion walls comprises a metal framework comprising at least two spaced uprights 1, advantageously constituted by tubes of square or rectangular section having the necessary robustness, each of these uprights being for example formed by two tubes 1a, 1b assembled by interlocking and bolting, or by profiles, or by a combination of tube and profile securely assembled in the extension of one another.
  • the upper part of the uprights 1 is rigidly secured to one of the ends of a cross member 2 arranged perpendicular to said upper part, this cross member being, for example, constituted by a robust metal profile.
  • each cross member is rigidly connected to the upper part of a stand 3 whose length is adjustable.
  • the lower part of the stand is advantageously constituted by a screw jack 4.
  • Each crutch 3 is parallel to the upper part of an upright 1, which constitutes, with said crutch and with the cross member 2, a kind of gantry.
  • the device according to the invention comprises at least two, or, more often than not, more than two spaced gantries thus produced and rigidly assembled by horizontal beams.
  • a fixed panel 5 for example constituted, in known manner itself, by a wooden frame coated with a vertical or formwork facing.
  • a movable cover 6 is arranged facing the cover 5 and suspended from the horizontal crosspieces 2, for example by means of rollers 7 bearing on the upper face of said crosspieces forming a guide rail and allowing the movement of the mobile cover 6 in the direction of the fixed panel 5 in order to proceed with the pouring of the concrete, or its removal from the latter, for carrying out the formwork.
  • FIG. 9 represents a particular arrangement of the upper part of each gantry, for the purpose to facilitate the movement of the movable form 6.
  • the cross member 2 of each gantry is equipped with an inclined raceway 27 provided with a rack 28, this inclined rack rising in the direction which moves away from the fixed panel 5.
  • the upper part of the frame of the movable form 6 is equipped with toothed wheels 29 meshing with the racks 28.
  • the rotation of these toothed wheels is effected by means of operating levers 30 provided, so known per se, by a snap-fastening by means of which they can be coupled to the axis of said wheels, in order to allow the unidirectional drive of the latter, in one direction or the other. It is thus possible to move the mobile panel 6 away, during formwork removal, effortlessly, while lifting it slightly, so that its base does not rub on the floor.
  • the uprights 1 comprise a part 1a which extends below the lower edge of the fixed panel 5, the length of this part 1a being for example substantially equal to the length of the remaining part 1b of said uprights on which said panel is fixed .
  • the end or lower part of the uprights 1 carries a leveling bridge 8 rigidly fixed, or arranged to be able to be rigidly fixed, by bolting, welding or otherwise on said uprights.
  • the uprights of the railing of this leveling bridge consist of the lower portion of hangers 9 suspended, via their upper end, from brackets 10 rigidly secured to the upper part of the uprights 1.
  • the position of the leveling platform 8, relative to the upper part of the scaffolding formwork, can be fixed (figure 1) or adjustable (figure 7).
  • the lower portion of the uprights 1 and the lines 9 can be executed in two parts, respectively 1c, 1d and 9a, 9b, assembled telescopically. These parts are provided with holes, respectively 31, 32 and 33, 34, regularly distributed over at least a portion of their length, for the passage of the rod of the bolts or other connecting members allowing the rigid assembly of said parts.
  • the lower portion of the uprights 1 and of the lines 9 thus has an adjustable length making it possible to adjust the position of the leveling bridge 8, in the vertical direction.
  • the part 1a of the uprights 1 which extends below the lower edge of the fixed panel 1 is provided with a support pad designated as a whole by the reference 11 in FIGS. 1 and 7 and, the formwork scaffolding according to the invention also comprises support shoes intended to be fixed to the wall portion (gable-veil) already produced, and to support the external uprights 1, these shoes being designated, as a whole, by the reference 12 in the figures 1 and 7.
  • the support pads 11 are arranged at a reduced distance from the lower edge of the fixed panel 5, at the upper part of the portion 1a of the uprights 1.
  • FIGS. 1 and 7 show the formwork scaffolding according to the invention placed in abutment, on the one hand, by means of the pads 11, on the shoes 12 fixed on the upper part of the portion of wall M already produced and, on the other hand, via the screw jacks 4 of the crutches 3, on the last floor P produced.
  • the dashed line in Figures 1 and 7 shows the approximation of the movable form 6 near the fixed form 5 to allow the pouring of the future portion of superimposed wall.
  • Each support shoe 11 comprises a small arm 13 rigidly secured to the upright 1 which carries it and arranged perpendicularly to the latter, this arm preferably being constituted by a tube of rectangular or square section.
  • the free end of this arm is provided with two opposite lateral branches 14 arranged perpendicular to said arm.
  • These two lateral branches are preferably formed by a single tube, of square section, embedded in a cutout in the end of the arm and welded to the latter.
  • the arm 13 carries a nut 15, for example fixed by welding, on the upper wall of said arm.
  • a threaded clamping rod 16 is screwed, arranged parallel to the arm 13 and part of which passes through the upright 1.
  • this rod is arranged to allow it to rotate; this end comprises, for example, a hole 16a for the passage of a bar or operating pin.
  • the opposite end or internal end of the rod 16 is provided with a base 17 in which said rod is mounted with freedom of rotation, the latter comprising, for example, a peripheral groove 16b in which is engaged, without excessive axial or lateral play, the edge of the hole formed in said base.
  • This base 17 is immobilized in rotation; it comprises, for example, a sole 17a resting, with a sliding ability, on the upper wall 13a of the tube 13.
  • the sole 17a of the base 17 has a length of a few centimeters so that a portion of the latter always remains disposed above the upper wall of the arm 13, so as to prevent said base from rotating.
  • a stop which can be constituted by a welding point 26 is placed on the rod 16, in front of the nut 15.
  • the position of the support pads 11 on the uprights 1 can be fixed ( Figure 2) or adjustable ( Figure 8).
  • the arm 13 of the support pads is fixed, for example by welding, on a support which can be constituted by a vertical plate or plate 35 movable along the uprights 1 and made integral with the latter by means of 'assembly members such as bolts 36 whose rods pass through holes with horizontal axes 37, 38, which have, respectively, the plate 35 and said uprights 1.
  • the latter are provided, at least in their portion located below of the fixed panel 5, of a plurality of holes 38 regularly distributed along said portion, to allow the position of the support pads 11 to be adjusted, such a position adjustment being desirable, due to the possible existence of 'openings in the facade wall running.
  • Each support shoe 12 comprises a flat bottom wall 18 which is provided with at least one hole 19, preferably disposed in the upper part of said wall, considering the position of use of the shoe.
  • This bottom wall is intended to be positioned vertically and the hole 19 is intended to allow the passage of the rod of a fixing member 20, such as a bolt for example, making it possible to fix the support shoe against a wall or other wall.
  • a fixing member 20 such as a bolt for example
  • the latter also includes a support plate 21 oriented perpendicular to the bottom wall 18 and disposed in front of the lower portion thereof.
  • This support plate 21 is delimited, on each side, by side walls 22 in the upper part of which is provided a hole 23 for the passage of the rod of a locking member 24, these side walls 22 being arranged perpendicular to the bottom wall 18 and the support plate.
  • the walls 18 and 22 are advantageously formed by a U-shaped profile and the support plate 21 is fixed by welding to the bottom wall 18 and to the two side walls 22.
  • Each support shoe further comprises two spaced guide ramps 25 placed in front of the support plate 21 and inclined towards the upper face of the latter to which said ramps are rigidly connected, for example by welding.
  • Each guide rail is, for example, constituted by a robust metal plate, a portion of which forms the rail itself is welded to the front edge of the support plate 21 and an extension of which is welded to the lower part of the bottom wall 18 and / or on the adjoining side wall 22.
  • the internal edges 25a of the guide ramps 25 have an oblique orientation relative to the median vertical plane of the shoe and they converge in the direction of the support plate 21.
  • the space e which separates the lower part of the ramps guide 25 is preferably much greater than the width of the arm 13 of the support pads 11 which is disposed between said ramps when the two elements of the support device according to the invention are in the functional junction position.
  • the spacing e ′ of the side walls 22 of the shoes 12 is much greater than the distance d between the free ends of the support legs 14 of the shoes 11.
  • the base 17 of the threaded wedging rod 16 of the pads 11, is brought, by rotation of said rod, to bear against the bottom wall 18 of the shoes 12 so as to prevent any movement of the frames in a direction perpendicular to the wall M.
  • the rod of the locking member 24 is engaged in the holes 23 so as to prevent any upward movement.
