Definitions

  • the present invention relates to a beam for a retaining curtain and a retaining curtain comprising such beams.
  • Retaining curtains formed, either exclusively of beams or beams and sheet piles, have been known for a long time. They have the advantage of presenting very important resistance modules for an advantageous surface weight.
  • the connections between two beams or a beam and a sheet pile are made at the edges of the flanges of the beams.
  • HZ an integrated system for making retaining curtains.
  • This integrated system includes special beams, called HZ beams.
  • the edge of the wings of these beams HZ ends with a substantially triangular section bead, which is projecting relative to the outer surface of the wing. On this beaded wing edge, it is possible to slide a RH or RZ-type connection profile making it possible to connect another HZ beam or AZ sheet pile.
  • a connecting system for joists with thick wings is known from the document DE 583 471 . These are small joists, the height of the soul being equal to the width of the wing, which can be mounted in the retaining curtain with their soul either perpendicular or parallel to the axis of the curtain.
  • a wing of this beam has a groove rolled or machined along each longitudinal edge in the inner surface of the wing and a bearing rolled or machined in the side edge of the wing. The groove and the bearing make it possible to connect the ends of the wings of two adjacent beams by means of special connector profiles and to connect a wing of a first beam transversely between the two wings of a second beam. It is therefore a very special connection system, which was designed in 1927 for a particular implementation of low joists and which has probably never been successful.
  • a first type of lock member includes a "bent finger” and "an inch” defining a lock chamber.
  • a second type of lock member comprises a bead adapted to be received in the lock chamber.
  • a projection to which several functions are assigned.
  • a first function would be to increase the stability of a stack of beams.
  • the elongated beam on a wing rests indeed on said projection and on the lock element of said first type, which has substantially the same height as said projection.
  • a second function would be to form a support for a guide element when driving a beam into the ground.
  • a third function would be to balance the cross sections of the wings with respect to the soul.
  • said projection would increase the section module of the beam.
  • the rolling of such claws and projections is a difficult operation and almost impossible for a beam with wings having a thickness of more than 22 mm.
  • the practice should still show if this new connection system is proving itself on construction sites.
  • An object of the present invention is to provide a beam that can be easily laminated with a higher resistance module, without having to increase its height significantly, and whose Installation in retaining curtains can be done using various connection systems that have proven themselves on construction sites.
  • a beam for retaining curtain according to claims 1, 3 or 4.
  • the reinforcement of the wings by a material thickness, located on the opposite side to the core, allows to significantly increase the resistance module of the beam, without any notable increase in height.
  • the non-reinforced wing tips, whose thickness is comparable to the wing thickness of a conventional beam for retaining curtains, allow on the other hand to use almost all connection systems known for the integration of a beam in a retaining curtain.
  • the connecting means carried by the wingtips comprise a connecting bead.
  • a beam of this type can be easily integrated into a retaining wall using connecting elements comparable to the "RH” or “RZ” type connection profiles of the "HZ” system of PROFILARBED SA. that the maximum thickness of the thickness of material is preferably greater than the height of the bead, so that the bead is recessed relative to a bearing surface formed by the material thickness of the wing.
  • the wing bead must have a triangular section. However, it is not excluded to design connecting profiles requiring a connecting bead with another section.
  • At least one of the lower thickness wing tips has a corrugated longitudinal profile to directly form the connecting means.
  • a beam of this type can for example be easily integrated into a retaining curtain as described in the patent application. EP-A-0072118 .
  • the coupling means may also comprise a connecting section for a sheet pile which is welded end to end on a lateral face of one of the wing tips of smaller thickness.
  • a connecting section for a sheet pile can also be carried by a U-shaped section slid on one of the wing tips of lower thickness and fixed to this wing tip by means of two angular welds. This latter embodiment is not the subject of the claims.
  • the extra material thickness has a symmetry with respect to the median plane of the core.
  • the extra thickness of material on the wing is advantageously divided in two by a longitudinal groove extending above the core.
  • the ratio between the thickness of said wingtips and the thickness of the core is preferably between 1.0 and 1.7.
  • the ratio between the maximum thickness of the wing at the thickness of the material and the thickness of the wingtips is preferably between 1.5 and 4.0.
  • the ends of the garments will preferably have a thickness of between 10 mm and 25 mm. If the maximum thickness of a wing at the thickness of material is between 40 mm and 60 mm, it will most often be ensured that in a retaining wall the connections are arranged set back from the bearing surfaces. formed by the extra thicknesses of material.
  • the present invention is especially interesting for increasing the resistance modulus of a high beam, that is to say for which the ratio between the core height (H) and the wing width (B) is greater than 2, because it makes it possible to obtain a notable increase in its resistance modulus without any significant additional increase in its height.
  • a retaining wall according to claims 11 or 12 at least two beams according to the invention are connected at their wings with connecting profiles.
  • the thicknesses of material advantageously form bearing surfaces which define a support plane arranged in front of the connecting profiles (in other words, the connecting profiles are arranged set back with respect to the support plane defined by the extra thicknesses of wings material). A lierne can then bear directly on the bearing surfaces formed by the material thicknesses, without being hindered by the connecting profiles.
  • the Fig. 1 shows two beams 10, 10 'connected to each other.
  • a beam 10, 10 ' comprises a core 12, 12' and two wings 14, 16, 14 ', 16'.

  • the height H of the core 12, 12 ' is approximately twice the width B of the flange 14, 16, 14', 16 '.
  • the two beams are connected at their flanges 14, 16, 14 ', 16' using connection profiles 18 known per se, for example using HR fittings marketed by PROFILARBED S.A. (Luxembourg).
  • the wings 14, 16, 14 ', 16' comprise along each longitudinal edge a bead 20, 20 'of substantially triangular section.
  • the connecting section 18 is slid over these longitudinal edges of the wings 14, 16, 14 ', 16', so that the connecting beads 20 engage the lock chambers of the connectors 18. This method of connection is well known and is widely used for the construction of retaining curtains.
  • the broken lines 22, 22 ' represent the trace of the outer face of the wings of a conventional HZ beam produced by PROFILARBED SA (Luxembourg). It can be seen that in the new beams 10, 10 ', the two wings 14, 16, 14', 16 'are reinforced on the opposite side to the core by a material allowance 24, 26, 24', 26 'which starts only at a certain distance from the edges of the wing. At a certain distance d1 from the edge of the wing, the thickness of the wing gradually increases to reach a maximum value e * at a distance d2 from the edge (d1 ⁇ d2).
  • the thickness of the wing 14 then remains equal to e * up to a distance d2 from the opposite edge of the wing, and then decreases symmetrically with respect to the median plane of the core 12, 12 '.
  • the extra thicknesses of material 24, 26, 24 ', 26' thus leave wing tips 21, 21 'having substantially the same thickness e as the wings of a conventional HZ beam.
  • These ends of garlic 21 carry the connecting beads 20, respectively other connecting means (cf. Fig. 5 and 8 ).
  • the thickness e * is about twice the thickness e of the wingtips 21. In practice, this ratio can vary between 1.5 and 4.0.
  • a thickness e * of the order of 50 mm allows the extra thicknesses 24, 26, 24 ', 26' to define bearing surfaces 27, 29, 27 ', 29' located in front of the profiles. fitting 18.
  • a link 31 which bears on the bearing surfaces 29, 29 'without being hindered by the connecting sections 18 connecting the wings 26 and 26'.
  • the thickness e of garlic ends 21 is generally between 10 mm and 25 mm.
  • the ratio between the thickness of the ends of the garments 21 and the thickness of the core 12 is generally between 1.0 and 1.7.
  • the Fig. 2 shows how two pairs 30, 32 of these beams 10, 10 'can form with a pair 34 of sheet pile Z a mixed retaining wall.
  • Fittings profiles 36, 36 'adapted to connect the sheet piles 34 to the flanges of the beams 30, 32 are for example those marketed by PROFILARBED SA (Luxembourg) under the designation connection RZ-U, respectively RZ-D.
