CARRIER ELEMENT FOR LATTICE STRUCTURES
The present invention relates to the elements carrying lattice structures of the kind comprising the fastening means adapted to receive the longilinear components that are repeated at predetermined intervals in the structure to be supported. It can be all kinds of structures in lattice welded or similar to meshes of longilinear elements of the type wire or rod, in particular, cable paths in industrial equipment, compartments, the most varied in the field of construction, and so on. Depending on the applications, the bearing surfaces of these structures can have different orientations and need fixing means suitably adapted for more or less complex construction and / or execution; it can be treated as fixation, on brackets, on support cords, on hanging, etc. The present invention proposes within this context a carrier element that adapts to the most diverse applications and configurations with a great ease of execution. The invention is essentially characterized by a section profile in the form of a channel with, as fixing means, notches cut on horseback on the edges of its back face and topped by a tongue arranged on this face over a fraction of its length. The notches thus cut out and topped over a part of their length by the tongue cut into the dorsal side of the profile constitute a housing that can be adapted for its dimensions and its repetition step for reception, by simply fitting the long-line components, wires or rods, of the structure in lattice to support. In the case of the vertical orientation of the structure, it can simply be recharged by gravity in the notches of the carrier element, whatever it may be, the fixation in the notches can be ensured by simply folding the tabs on the component put in place . According to an advantageous embodiment of the invention, the channel profiles are grouped in pairs of two channel profiles in the flange of the wings of said profile with a generally omega-shaped base. This leads, in this way, to a structure element that offers outstanding features of mechanical strength in view of the constitution of an element usable especially in beam, bracket or others. The base profile can conveniently be bent once or twice for the formation of a bracket or a suspension element, the fixing holes for mounting on a vertical or horizontal wall being able to be arranged, the limits then being limited. arrangements of notches of the carrier to a fraction of the profile. According to another embodiment, the invention also provides for the pairwise association of two omega base profiles assembled from the back to form a still more robust structure element usable in a beam or pole with the possibility of access on four sides. Among those applications the base profile may not include notches and tabs over all or part of its extension. The characteristics and advantages of the invention will, on the other hand, reappear from the description that follows, by way of example, with reference to the attached schematic drawings, on which: FIGURE 1 is a perspective view of a section of profile according to the invention.

FIGURE 12 shows a similar section provided with a fixing leg. FIGURE 13 shows perspective, an example of the arrangement that forms a pendant. FIGURE 14 shows the detail of a fixation piece incorporated in the arrangement of FIGURE 13. FIGURE 15 shows an example of application of a double bracket similar to that of FIGURE 5 with mounting on a pole constituted by a carrier element according to FIGURE 8. Following the embodiment chosen and shown in figures 1 and 2, a support element according to the invention is constituted by a profile 10 of generally inverted omega shape with a flat bottom between two enlarged side faces 11, 12 , each constituting with a plane 13, 14 and a fallen rim 15, 16, a raised channel profile raised above the bottom 10 and open in the direction thereof. FIGURE 10 shows how such a profile is made by profiling from a sheet metal strip 1 of corresponding width, the lines in mixed lines marked from 0-1 to 4-6 indicate the fold lines between successive adjacent zones. Prior to the formation, a series of aligned holes 2 must be cut out on the flat bottom 10. On the other hand, horses on the folding lines 1-3, 3-5, on the one hand, and on the other hand, 2- 4, 4-6, on the other hand, rectangular areas marked 3 and 4, of a certain length L, adapted to separate after folding and thus leave, between each of the channel profiles, the corresponding notches visible on FIG. 1, which follow one another with a certain pitch P. After bending, finally, in the planes 13 and 14, rectangular sections 5, 6 of length Ll are cut, so as to arrange them in the corresponding plane with tongues 7. , 8 which extend over the residual fraction L2 of the length L of each notch. It is thus seen that the carrier element thus constituted has, on the dorsal side, each of the two inverted channel profiles terminated by the flat bottom 10, a series of notches 3, 4 of length L, which are repeated at a pitch P and each including a cover tab 7, 8 cut into the bottom wall 13, 14 of the channel. In the example of the application illustrated in FIGS. 3 and 4, the carrier element is constituted on only one of the branches of a profile 20 formed with two branches 21, 22 arranged at right angles on the one hand and on the other hand, on one side elbow 23, only the branch 21 being encased in the manner described with, in this example, in each of the bottom walls of the channel 13, 14, a series limited to three notches to respectively receive the three chain wires 31, 32, 33 of a cable path section 30 in trellis where the mentioned chain wires are, in a usual manner, welded on the wires of the weft 34, 35 carrying, on the other hand, the overlaid flange chain wires 36, 37. As can be seen on FIGURE 4, each associated spade wire such as 32 is housed in a corresponding notch, such as 4, and tongue 8 can be bent if desired over the wire thus housed to ensure fixation. This system of hook by tab allows to immobilize all the longilinear elements of round, square or other section that does not exceed the height of the notch. The locking is effected by deformation against the inside of the tongue, which will thus adapt to a generator of the longilinear element, blocking it at the bottom of the notch. In this application example of FIGURE 3, the bracket 20 is adapted to be fixed by bolts, for example, of its branch 22 not enmeshed on a vertical support wall. FIGURE 5 shows an example of a double-bracket structure with three branches 41, 42, 43, linked together by the right angle elbow areas 44, 45. Here again, only the branch 41 that is grooved, the fixation is possible also by the branch 43 on any surface of horizontal support, roof or other. However, the application example of a cable path is not limiting, the support element according to the invention is intended for the assembly of all kinds of lattice structure with meshes of wire or rod type longilinear elements of all shapes of cylindrical section or other. These longitudinally parallel elements, which are longitudinally parallel along a transverse cross-sectional element, can be arranged in mutually crossing points by welding or otherwise. It may be particularly structures, decoration, partition walls, false ceilings, etc., with appropriate adaptations of the parameters of the system according to the invention, namely the width Ll of the passages arranged by the tabs, (which will correspond, in generally, at the height of the notches), the total length L is the repetition step of these. The perforations 2 arranged in the flat bottom of the profile 10 in omega, will allow the fixation on all support: walls, ceilings, beams, floors, but also agree for the possibility of the eventual assembly of two profiles, 10, 10 'according to the scheme of Figures 6 and 7 through the bolted fastening, if desired, all to facilitate the possibility of eventual assembly by electric spot welding or the wheel. The assembly thus constituted then forms an X-beam which offers particularly desirable characteristics from the point of view of mechanical strength, but also from the point of view of functionalities. The profile in X as illustrated especially in FIGURE 7 thus offers the possibilities of fixing on all four sides and can be conveniently used as a beam in a structural assembly; it can be seen especially the use as support in a cable path installation in the applications of the type called "pendant". In the modality of the profile as illustrated in figures 8 and 9, we find in the series of wings 11, 13, 15; and 12, 14, 16, flange flanges 17, 18, turned inwards constituting a structure of the "chest" genre, of four dimensions with, on the pairs of opposite faces, an anchor rail shape. The modality opens the possibilities for the realization of carrier structures or hanging systems for the fixation of bead brackets. The invention thus opens up vast possibilities for developments and applications in various fields, which is what it is proposed to comment on hereinafter with reference to figures 11 to 15. It is convenient to reconsider to start, the carrier element according to the invention as the illustrated in its most elementary form in figures 11 and 12. When in the embodiments considered above of these carrier elements, grouped by pairs in flange wings of an omega base profile, a carrier element in the The shape of a single channel profile with two wings 11, 15 which are symmetrically present on both sides of the flat bottom 13. The two wings of the profile can be of equal lengths or of different lengths, as in the previous embodiments. These two wings are not necessarily symmetrical in length or shape or angle. The channel profile may also be part of a general tubular profile. But in all cases the tabs 7 cut on the dorsal side of the profile, all of which can be bent inwards, will never be in projection and will not form, therefore, any roughness susceptible of any aggressive action with respect to objects, cables or other that could have to move by sliding to the contact of the dorsal face of the carrier element. Such a carrier element can be supported and fixed by all known means in any spatial, horizontal, vertical or other position, with a lattice structure, whether perched or suspended, as the case may be. Thus, only by way of example, the carrier element of FIGURE 12 is provided with the tip of a fixing leg formed in extension of the dorsal face 13, optionally folded according to a given angle, and pierced with at least one fixing hole on it. any associated support in view of a vertical, horizontal, inverted or other placement. FIGURE 13 illustrates an application of the pendant type in which there is a section 60 of double omega profiling 60 of the sort illustrated in FIGURE 8 that descends vertically from a suspension member 61 in the form of a stirrup including a bottom wall 62 perforated with fixing holes by means of bolts or by pulling on bottoms, for example, for a roof structure or for a beam or the like (not shown), and two arms 63, 64 receiving the suspension shafts 65, 66 cooperating with the perforations (not detailed) of the flat bottoms of the omega profiles that make up the double 60 profile. As you can see in the sectional view of FIGURE 9, you can see both sides of these flat bottoms and at the end of the wings 11 and 12 a box structure as the four-dimensional 13, 15, 17 adapted to form two pairs of opposite anchoring rails. In this case, the section 60 of profiling does not include a notch or a tongue. In the application illustrated in FIGS. 13 and 14, these anchoring rails are used in pairs for the shoring of a bracket 70 on each side by means of the fixing legs 67 equipped with grooves 68 possibly provided with notches (shown here) that the grooves (the grooves) come to rest on the retaining faces like the chests 15 through rails such as the 17 and the fixing nuts 69. The two squares thus fixed in space adapt, for example, to the mounting of the bolt fastening means 71 of a beam 72 equally in double omega, but of the type illustrated in FIGURE 7, with the flange formation of the wings of the lower omega profiling only of the carrier elements 73 , 74 with notches and tabs as described hereinabove, for a lattice structure 75 indicated schematically in mixed stripes and which may form part of a roof, for example. FIGURE 15 shows an example of the use in a pole of a section 80 of a beam structure with an X-section according to FIGS. 8 and 9. Here again, a double central wall 81 resulting from the fixing of the backs of the two profiles with omega base, two opposite housings 82, 83 of section in the form of an enlarged channel and, on both sides of these housings, two pairs of chests 84 and 85 adapted to form the anchoring rails or guides for the sliding parts of corresponding shapes, whose fixing legs 67 mentioned constitute examples. In the application illustrated in FIGURE 15, only the side housing 82 is used for fixing by snapping and bolting (not detailed) a double bracket 90 similar to that of FIGURE 5 with mounting on its upper branch 91 of a section 92 of beam structure similar to that of post 80 but in horizontal position. It is thus seen that the double omega profiling according to the invention offers the means for mounting the parts to be supported in four radiating directions. First of all, there is a pair of wide channels delimited by the wings of each base profiling with respect to the corresponding flat bottom: this is the case of the channels marked 82 and 83 of FIGURE 15, for example. . Secondly, the second pair of perpendicular orientation channels constituting on this same figure the anchoring rails 84, 85 are disposed. The invention is not well understood limited to the details of the embodiments previously described herein. simple illustration way. It is particularly worth noting that the carrier elements and the beam structures can be metallic or non-metallic, for example deformable plastic materials or any other material having a sufficient mechanical behavior to undergo deformation and preserve this deformation.
