Definitions

  • a sealing plug for an electrical cable against air infiItrations into buiIdings and an eleclrica1 cable laying-out method The field of the invention is related to the problem of air infiltrations into buildings through inlets and outlets of cables, tubes and other electrical conducts,. in particular, but not exclusively into the external thermal shells of such buildings.
  • the word "conduct” means here the tube where an electrical cable extends, ail the same being sheathed for insulation reasons, and which, is built-in within the shells, walls and partitions, the sheathed electrical cable being able as far as it is concerned to be (removed out of its conduct so as to be replaced.
  • silicone or foam can be used, but such solutions are more and more rejected by the agreement organisations.
  • the Applicant has looked for a universal solution, i.e. being able to be applied for any of the three above-mentioned sealing types (a, b, c) and thus has proposed the present invention.
  • the invention thus relates first of ail to a sealing plug for preventing air infiltrations via an electrical cable inlet or outlet through a building shell or partition, the plug being tubular, arranged to cross the shell, provided on the external side with a pierceable plugging and sealing membrane and the plug being made of a flexible material.
  • the plug is made of a flexible material due to the fact that the conducts are not rectilinear, that the plug can perfectly suit to passing holes of different diameters, even if a plurality of plugs can be envisaged, each one only for a given range of hole diameters, without affecting anyway the universal character of the plug, and that a passing hole is not necessarily clean.
  • the plug comprises an external plugging -membrane that can be pierced by a cable or an electrical conduct threaded into the plug.
  • Such membrane is preferably pre ⁇ boreo with an electrical cable or wire passing orifice.
  • This allows in particular the invention to be used for passing a flexible electrical cable or wire, which is not sufficiently stiff to be able to be used for piercing the membrane.
  • This also allows to reduce the effort being necessary to cross the membrane with a wire or a cable, the orifice being able to create a breaking initiation and guiding the cable or the wire upon crossing the membrane .
  • the diameter of such orifice is preferably smaller than the diameter of the electrical cable or wire adapted for crossing the plug membrane. Such diameter may be larger than 0.1 ram and is for example comprised between 0.1 and 1 cm.
  • the plug could naturally receive one or more electrical cables.
  • the plug has a diameter comprised between the external diameter of the conduct, on. which it is adapted to be mounted or made and a diameter increased by about 20 mm. with respect to the diameter of the conduct.
  • the plug can for example have a diameter comprised between 10 and 100 mm, preferably between 10 and 70 ram, more preferably between 20 and 40 nun. Its length depends in particular on the application being envisaged. In the case where it is used in art inner partition of the building, it may have a length comprised between 45 and 150 mm. In the case where it is used in an external building shell, it -nay have a length corfiprised between 100 and 400 mm.
  • the material thereof is preferably elastically deformable.
  • the plug is for instance made of EPDM, It has preferably a hardness comprised between 40 and 70 Shore A, for example 60 Shore A.
  • the external wall thereof is rugged so as to suit better to the diameter and the surface condition of the wall of the passing hole, in which it is to be introduced.
  • the external wall of the sealing plug comprises radial fins, which may have different diameters and different thicknesses (for instance, comprised between about 0.5 and 2 ram).
  • the fins can have any shape and be for instance rectilinear, undulated, etc.
  • the fins can be interconnected by longitudinal or slanted webs, thereby defining small cavities between the fins and thus limiting the risks of a thermal bridge across the shell or the partition.
  • Such radial fins provide the cooperation between the external wall of the sealing plug and the wall of the passing hole, in which it is to be introduced.
  • the plug thus adheres to the wall of the hole.
  • the plug can easily extend through two separate portions of the external thermal shell of a building. Thus, there is no loss of sealing staterial as it was the case when such material was injected with a gun .
  • its internal wall is ragged. It can comprise radial ribs. This allows the plug behavior on the cable passing sheath or conduct to be improved, in particular when the plug is assembled on the sheath. This is particularly advantageous, since, when the membrane of the plug is crossed by an electrical wire or cable, it can foe envisaged for the plug laying-out operator to be able to draw on the cable or the wire so as to adjust its length going beyond the plug, with no risk for the latter to be separated from the sheath, even when such operation is blindly carried out.
  • the radial ribs are preferably flexible ana deferrable.
  • the sealing plug according to the invention comprises at least one external sealing collar in abutment with the external thermal shell, into which the plug is supposed to be introduced.
  • the sealing plug can comprise an extension extending beyond the collar so as to be able to be anchored in a facade coating panel.
  • the plug can comprise at least two axial tubular parts, a first part being open on both axial ends thereof, and a second part being open on one of the axial ends thereof and closed on the other of the axial ends thereof (thus forming a pieroeabie plugging membrane ⁇ , both parts being independent or connected together so as to form one single part, which could be cut in order to be able to share the parts from each other.
  • the sealing plug can correspond to a third tubular part being open on both ends thereof, one of the ends thereof bearing an external sealing collar.
  • each tubular part has a smaller length than a complete plug ⁇ made of the assembly of the above mentioned parts) and is thus easier to be used than a complete plug and, in particular, to be embedded into a cable passing conduct or sheath.
  • the present invention also relates to an assembly comprising a sealing plug as above described and a tubular electrical cable passing sheath, which can be ringed or not, the pl3 ⁇ 4g being for instance mounted on an end of the sheath.
  • the sheath can have a diameter comprised between 10 and 50 mm and has typically a diameter of about 16, 20, 25, 32, 40 or 50 mm.
  • the sheath can be made of a plastic material or a metal being quite stiff and be made flexible through its ringed shape.
  • the plug in a flexible material allows the sheath some flexibility to be preserved.
  • the sheath is in particular a sheath fraction, i.e. a sheath of a predetermined length, thereby avoiding the operator to out the sheath before laying-out .
  • the external wall of the plug comprises radial fins and an annular groove on the basis of at least one side of each of such fins, the fins being deformabie and each groove being shaped to receive at least one part of the fin corresponding to the deformed condition.
  • the groove can have a determined width depending on the radial height of the corresponding fin so that such fin may be engaged into such groove over substantially the whole height thereof in a deformed position.
  • the groove can have a determined depth depending on the axial thickness of the corresponding fin so that such fin can be engaged into such groove over substantially the whole thickness thereof in a deformed position.
  • the invention still relates to a method for manufacturing such assembly, wherein the sheath is embedded into a prefabricated plug or the plug is made on the sheath, for instance by over-moulding.
  • the fabrication of the plug directly on the sheath enables in particular to make a unique product comprising a ⁇ pre-cut) sheath fraction and a plug and thus avoids the plug to be mounted on the sheath, thereby reducing the laying-out time, since the operarator does not need to cut the sheath and to mount the plug on the cut sheath.
  • This also allows the plug to be anchored on the sheath, the plug material being able to be inserted between the rings of the sheath.
  • the invention also relates to a laying-cat method for at least one electrical cable through a shell or a partition in a building so as to prevent air infiltrations through the cable passage through the shell, wherein a through-hole is bored in the shell or the partition, the plug is then mounted on a cable passing sheath or on the cable, and then the assembly is inserted into the hole.
