Definitions

  • the present invention relates to a connecting flange for assembling beams, more particularly intended to allow the connection of wooden beams arranged perpendicularly and at least some of which are preferably provided with a plurality of transverse holes passing through them right through. and regularly spaced. It also relates to wooden frames made using this connecting flange and standardized beams with perforations distributed over their entire length.
  • the connecting flange according to the invention can be used to fix the horizontal dies or twin beams of the frameworks of the forms, on the uprights of the latter; these twin channels constituting stiffening elements and allowing the establishment and support of the tie rods of said formwork.
  • An object of the present invention is therefore to remedy the aforementioned drawbacks of the connection devices currently used for assembling twin beams on beams arranged perpendicularly.
  • the connecting flange according to the invention it is therefore possible to securely couple two beams paired with a third arranged perpendicularly, by pressing them strongly against the latter, while ensuring both rapid assembly and maintenance a desirable spacing between said twin beams, for example for the passage of tie rods in the case of an application to the execution of formwork.
  • connection flanges used in combination with standardized perforated beams, make it possible to conveniently and quickly produce frames of various nature comprising vertical elements and horizontal elements whose spacings can be very variable, depending on needs and the destination of said frameworks, these beams and these connecting flanges having, in fact, the advantage of offering multiple possibilities as regards the locations of the mechanical connections of said vertical and horizontal elements.
  • this connecting flange comprises a stirrup 1, a movable jaw 3 and a screw-nut system connecting said stirrup and said jaw.
  • This screw-nut system is advantageously constituted by a threaded rod 2 which is provided with the top of the stirrup 1 and on the extreme portion of which is mounted a tightening nut 4, said threaded rod passing through the movable jaw 3.
  • the stirrup 1 has two spaced apart and symmetrical branches 1a, arranged to be able to be fixed on a beam.
  • each of the branches 1a has, near its free end, a hole 1b aligned with that of the second branch, for the passage of the rod 5a of a connecting member 5 which may be constituted by a bolt .
  • the branches 1a of the stirrup 1 are made of a metal endowed with an elastic bending capacity and consist of two portions 1a 'and 1a "meeting by forming a dihedral protruding whose edge 1 is oriented towards the outside.
  • the portions 1a ′ intended to enclose the beam on which the stirrup is fixed are arranged in parallel or substantially parallel, while the portions 1a 1 ending at the top 1 of said stirrup, converge towards said summit.
  • the head 2a thereof can have a polygonal shape, for example square, or have a round shape, as illustrated, but, in the latter case, it comprises, at near its head, a collar 2b of square section engaged in a square hole 1e formed in the top 1d of the stirrup 1 for the passage of the rod of said screw.
  • the threaded rod 2 is aligned with the longitudinal axis of the stirrup 1 and it is rigidly secured thereto, by wedging between the upper ends of its branches 1a and / or by welding or crimping. It crosses the movable clamping jaw 3, the central part of which comprises, for this purpose, a hole 3a for the passage of said rod.
  • the movable clamping jaw 3 is constituted by a robust plate folded to include two lateral support wings 3b and a central depression 3c in the bottom 3d of which is provided the hole 3a allowing the passage of the threaded rod 2 of the screw system. nut.
  • This central depression 3c has, externally, a width L equal to or substantially equal to the width L 'of the arms 1a of the stirrup, as shown in FIG. 2.
  • Figures 4 to 6 illustrate the use of the flange according to the invention to achieve the coupling of two twin beams 6, arranged in parallel, to a third beam 7 oriented perpendicular to said twin beams.
  • the stirrup 1 is arranged in overlap on the beam 7 and it is firmly fixed on the latter by means of the bolt 5 which passes through a bore 7a formed in the thickness of said beam.
  • the upper part of the stirrup 1 is disposed between the twin beams 6 applied against the perpendicular beam 7 and the movable clamping jaw 3 is placed in abutment, via the internal face of its lateral wings 3b, against the face external of said twin beams.
  • the rotation of the nut 4 mounted on the threaded rod 2, in the tightening direction, causes a movement of the movable jaw 3 in the direction of the stirrup 1, the axial displacement of said nut which bears against the bottom 3d of the depression 3c of said movable jaw 3 causing, in fact, a corresponding displacement of the latter.
  • the spacing between the twin beams 6 allowing, for example, the passage of the tie rods in the case of the application of the invention to the production of formwork panels, is obtained by the presence of the central depression 3c of the movable jaw and of the upper part of the stirrup 1 between said twin beams.
  • the connecting flanges according to the invention can advantageously be used in combination with standardized beams 6, 7, provided with perforations 6a, 7a, regularly distributed over their entire length and arranged along a median line.
  • the distance D between the center of the fixing holes 1 and the top of the branches 1a of the stirrup 1 is much greater than the distance D 'which separates the center of the hole or holes 6a or 7a of which are provided with the beams 6 or 7, any one of the longitudinal edges 6b or 7b of said beams, respectively.
  • the connecting flange according to the invention can be used for the assembly of beams made of any material, but it is particularly advantageous in its application to the assembly of wooden beams.
  • the invention also relates to wooden frames using the previously described connecting flanges, in combination with standardized beams 6, 7 provided with a plurality of transverse perforations 6a, 7a, passing right through them. These perforations are regularly spaced created and distributed over the entire length of said beams. In addition, they are oriented in the thickness direction of the beams and are arranged along the center line of the width of the latter, equidistant from the opposite longitudinal faces corresponding to the thickness of said beams.
  • the beams of this kind and the connecting flanges according to the invention offer a very large number of possibilities with regard to the locations of the mechanical connections of the horizontal and vertical elements of the frames, which can therefore be assembled with variable spacings.
  • FIG. 7 shows a portion of formwork or formwork, the panels of which comprise a wooden frame executed according to the invention and a formwork surface 9 fixed to said frame.
  • This frame comprises a plurality of uprights and two dies each formed by two twin beams assembled to said uprights by means of connecting flanges according to the invention, said uprights and said dies being constituted by stardardized beams 7, 6, executed in wood. and provided with perforations 7a, 6a, respectively, regularly distributed over their entire length.
  • the dies formed by the twin beams 6 could be positioned at different levels and that the uprights formed by the beams 7 could be otherwise spaced without resulting in any complication of assembly said channels on said uprights.
  • the movable clamping jaw 10 of the connecting flange is constituted by a circular support plate 10a provided with a central nut 10b having, externally, a cylindrical surface 10c and arranged below the plane in which said support plate is located.
  • the nut proper is, for example, rigidly fixed, by welding or otherwise, in the lower part of a cylinder 10d rigidly attached, by means of its upper end, to the edge of a circular central opening 11 formed in plate 10a.
  • the outside diameter L " of the nut 10b-10d is advantageously equal to the width L 'of the branches 1a of the stirrup of the connecting flange.
  • the nut 1 Ob-1 Od incorporated in the movable clamping jaw 10 and integral in rotation with the latter, is mounted on the threaded rod 2 rigidly integral with the stirrup 1. It is understood that the drive in rotation of the jaw mobile 10, in the screwing direction, allows it to be brought closer to the stirrup 1, while its rotational drive in the opposite direction moves it away from said stirrup.
  • the clamping jaw 10 When the connecting flange is used to assemble two twin beams 6 with a third beam 7 arranged perpendicular to the other two, the clamping jaw 10 is placed in abutment against the outer edge of said twin beams, by means of its circular plate 10a, while its nut 10b-10d is disposed between the latter ( Figure 11).
  • the nut 10b-10d and the bracket 1 thus make it possible to reserve a space between the twin beams 6.
  • the support plate 10a of the movable jaw 10 is provided with at least two fingers 10e, diametrically opposed, allowing the rotational drive of said movable jaw, by means of a lever 12 wedged against said fingers, this lever can be constituted by a simple iron bar, as shown in Figure 11.
  • This arrangement allows the tightening and loosening of the movable jaw 10 of the connecting flanges, without the use of a key specially adapted to nut of said jaw.
