Abstract
Abstract A distribution and connection column for electrically conductive cables comprising a beam having a central web and two pairs of flanges extending on opposite sides of the web. A median zone of the web is formed as a U-section with flanges which are parallel to the flanges of the beam, and the lateral extension of these flanges is less than that of the flanges of the beam. There is thus formed two longitudinally extending channels each adapted for receiving electrically conductive cables, the first channel being located inside the U-section of the web, and the second channel defined partly by the web and one pair of flanges of the beam, and partly by the U-section of the web.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
118 words
A distribution and connection column for electrically conductive cables, comprising a beam having in section a central web, and two pairs of flanges extending on two opposite sides of the central web, the median zone of the web being formed as a Usection having flanges which are parallel to the flanges of the beam, the lateral extension of the flanges of the U-section being less than that of the flanges of the beam, and the beam thus forming two separate longitudinally extending casings for receiving said cables, the first casing being located inside the U-section, and the second casing being defined partly by the web and one pair of flanges of the beam, and partly by the U-section.
Claim 2
Dependent Claim
118 words
A distribution and connection column for electrically conductive cables, comprising a beam having in section a central web, and two pairs of flanges extending on two opposite sides of the central web, the median zone of the web being formed as a Usection having flanges which are parallel to the flanges of the beam, the lateral extension of the flanges of the U-section being less than that of the flanges of the beam, and the beam thus forming two separate longitudinally extending casings for receiving said cables, the first casing being located inside the U-section, and the second casing being defined partly by the web and one pair of flanges of the beam, and partly by the U-section.
Claim 3
Dependent Claim
38 words
A column according to claim 1, wherein the ends of the flanges of the U-section defining the first casing are provided with positioning means for the positioning of a cover having spaced perforations for thE fastening of connectors.
Claim 4
Dependent Claim
83 words
A column according to claim 2, wherein electrical current conductors are located in one of the casings and signal transmission cables are located in the other, and apertures spaced in the longitudinal direction are provided in the central portion of the web to serve as communication means between the two casings, and a cover for the first casing is provided located by said positioning means, said cover including connectors adapted for connection to the electric current conductors and to the signal transmission cables.
Claim 5
Dependent Claim
26 words
A column according to claim 3, wherein the electric current conductors are disposed in the first casing and the connectors are adapted to receive connecting prongs.
Claim 6
Dependent Claim
119 words
A column according to claim 1, wherein the two pairs of flanges of the beams are substantially symmetrical in relation to the web and the column is provided with height adjusting means for adjusting and fixing the height thereof, these means comprising two profiled adjustment elements whose external profile matches at least partly the internal profile defined by the two pairs of flanges and the portion of the web situated outside the U-section, each of these profiled adjustment elements being adapted to slide on each side of the web of the beam and being provided with two flanges connected by a base which closes the gap existing between the ends of the two pairs of flanges of the beam.
Claim 7
Dependent Claim
82 words
A column according to claim 5, wherein the column includes fastening means comprising at least one rod disposed in the gap between the web of the beam and each profiled adjustment element, this rod being attached to either of the two elements comprising the beam and the profiled adjustment element and locked on the other element by a clamping means accessible from outside, the free end of the two profiled adjustment elements being engaged with a base for fastening to the floor.
Claim 8
Dependent Claim
35 words
A column according to claim 6, wherein the profiled adjustment elements are arranged outside their zone of engagement with the beam, in a one-piece ring which closely surrounds them and which is adjustable in position.
Claim 9
Dependent Claim
92 words
A column according to claim 1, wherein the column is provided at its upper end with claw elements fastened face to face on each side of the central web and which are provided with claws projecting from the end of the beam, and an element is provided for fastening to a ceiling having apertures into which the claws can be introduced, the claws and the apertures being disposed concentrically at regular angular intervals in such a manner that the column can be secured against rotation in any of several possible angular positions.
Claim 10
Dependent Claim
33 words
An assembly comprising at least one column as claimed in claim 1, in combination with a horizontal conduit adapted to receive electrically conductive cables and means connecting said horizontal conduit to said column.
Claim 11
Dependent Claim
87 words
An assembly according to claim 9, wherein the column is connected by said connecting means at its upper end to said horizontal conduit, and said conduit comprises an I-section beam having a vertical central partition constituting the web, an upper flange having a flat upper surface for fastening to a ceiling, and a lower flange the longitudinal edges of which are directed upwardly towards the upper flange and which define, with the central partition, two parallel channels separated by said partition and adapted to receive said cables.
