Definitions

  • the invention relates to a yoke adaptable to tubes of different diameters and thicknesses, having two arms integral with a frustoconical foot, intended to be fixed to the end of a tube.
  • the yoke is optionally formed of two identical elements, each comprising an arm and a half of a foot, forming a half truncated cone, assembled along at least one edge.
  • Document GB-A-761 879 discloses a yoke comprising two arms each secured to a foot designed to be welded to the end of a hollow tube, providing access to the interior of the tube.
  • this screed is not designed to fit tubes of different diameters.
  • French patent application No. 2 612 576 describes a yoke, adaptable to tubes of different diameters, monobloc or obtained from two elements which were assembled along their edges by a continuous weld bead. After welding of the yokes on the ends of the tube, the assembly is practically sealed and protected from internal corrosion.
  • the assemblies are used in particularly severe climatic conditions, such as in a marine environment, or in a corrosive environment, it is necessary to apply to them a protective treatment comprising for example the deposition of metallic layers such as example as galvanizing.
  • a protective treatment comprising for example the deposition of metallic layers such as example as galvanizing.
  • the temperature of the metal bath in which they are immersed being relatively high, it is necessary to provide vents in order to ensure that the pressure in the tube is balanced with the atmosphere.
  • vents are formed, in the case of yokes formed by two assembled elements, by the non-welded parts of the foot.
  • vents generally provided allow the circulation of ambling air and therefore conspire corrosion of the interior of the assemblies, without however being large enough to allow the free passage of the bath in the tube, nor to let the bath which has flowed could be introduced and which is retained between the frustoconical foot and the wall of the tube, during the draining.
  • the object of the invention is to allow the deposition of a practically uniform layer of a liquid protective product or metal on the internal walls of an assembly formed by the yokes welded to the tube, by modifying the yokes object of the aforementioned request.
  • a hollow yoke comprising two arms integral with a foot intended to be fixed to the end of a tube with at least between the two arms a median opening communicating with the hollow interior of the foot and extending along a plane parallel to the planes of the arms, characterized in that the foot of the yoke has a frustoconical shape whose large base carries the arms of the yoke, the external frustoconical side surface of the foot being intended to penetrate into the open end of a tube with which it is secured.
  • Figure 1 is a sectional view through the plane of symmetry perpendicular to the arms of a yoke according to an embodiment of the invention.
  • FIG. 2 is a view along II of FIG. 1.
  • FIG. 3 is a top view of a yoke element according to FIG. 1.
  • FIG. 4 is a sectional view along IV-IV of FIG. 3.
  • Figure 5 is a sectional view through the plane of symmetry perpendicular to the arms of a yoke according to another embodiment of the invention.
  • FIG. 6 is a view along VI of FIG. 5.
  • FIG. 7 is a top view of a yoke element according to FIG. 5.
  • FIG. 8 is a sectional view along VII-VII of FIG. 7.
  • the yoke mounted at the end of a tubular bar T, has two arms 1, 2 in which will be or are drilled coaxial holes 3, 4 intended to receive bolts of attachment to a fin of an assembly knot.
  • the arms 1, 2 are integral with a foot 7 which has a frustoconical shape.
  • the large base of the truncated cone carries the arms 1 and 2 which are in planes parallel to each other and parallel to the axis of the truncated cone.
  • the frustoconical lateral surface of the foot is capable of being applied against the edges of the end of the tubes T forming, for example, the bars of a lattice structure.
  • the foot carries on its inner surface and along at least two generatrices, ribs 8 for reinforcement.
  • ribs 8 for reinforcement.
  • projections 9 which are preferably arranged according to the same generatrices as the internal ribs 8.
  • the assembly formed of the tube closed at its ends by the yokes, is suspended vertically and the lateral openings 11 allow the evacuation of the bath which otherwise would remain trapped in the volume V.
  • the openings 10 and 11 are obtained by punching, drilling, etc. or by cores provided in the molds.
  • the openings are formed, during the manufacture of said elements, by forging-stamping, or by cores provided in the injection molds.
  • the edges 12A, 12B which is in a plane substantially parallel to the planes of the arms, has in its median part, a median notch 10, at least one of the edges 13A or 13B of the tapered half-feet also has a lateral notch 11.
  • edge parts 12A, 12B which are in contact are joined by any known method such as for example: welding, soldering, bonding, etc.
  • the edges of the central opening 10 form, with the inner wall of the foot and the inner face of the arms, a surface continuous curve 14.
  • This form of opening allows the flow of the protective bath without risk of retention.
  • FIGS. 5 to 8 The embodiment shown in FIGS. 5 to 8 is in all respects similar to that of the previous example except as regards the internal ribs 15 of the elements. These ribs have, over at least part of their length, an edge 16 extending along the axis of the yoke and by which the elements 1 and 2 will be kept assembled.
  • the formation of the median and lateral openings allows in particular the protection by metal bath of the internal surfaces of the tube-screed assembly after it is mounted and thus avoids, as was the case when the parts had to be protected before assembly , the formation of corrosion zones that are difficult to protect, even after recovery.
