  The present invention relates to an armature, in particular for the support of false ceilings. Although more particularly intended for such applications, it can also be self-sufficient and

  equip premises without false ceilings.

  As represented in FIG. 1, the armature according to the invention consists of at least rails 1; la, lb, distributed according to a given configuration. Said rails la, lb are provided, in particular, at the ceiling of the premises which they must equip and are arranged, for example,

  substantially parallel to said ceiling.

  According to the invention, said rails 1a, 1b have a tubular structure defining an internal cavity 2. In addition, said rails 1a, 1b, comprise, inside said cavity 2, hooking means 3 so as to be able to accommodate at least fluid distribution circuits

  and / or first elements of building technical equipment.

  The frame according to the invention can thus be provided, for example, with electrical wiring, air ducts, water supply pipes, lighting elements, fire protection.

and / or others.

  As further developed, said rails 1a, 1b are, for

example, of reduced section.

  Furthermore, said rails are constituted, at least, of the first rails la, said carrier rails, and second rails lb said cross rails, able to intersect, said inner cavities 2 of each of said carrier rails and spacers lb communicating between they so as to define a network of

2752858

  conduits corresponding, at least partially, to said configuration.

  As represented in FIG. 2, said configuration consists, in particular, of a substantially square mesh. The carrier rails are arranged, for example, in a first direction and through the premises to be equipped by being regularly spaced from each other. The spacer rails lb are arranged in a second direction, orthogonal to the

  first, and are regularly spaced between said carrier rails la.

  Referring back to FIG. 1, it can be seen that, according to the exemplary embodiment shown, it is provided, at each intersection, two different spacer rails Ib, in the extension of one another around

of a carrier rail la.

  Said carrier rails have, for example, on their lateral sides 4 windows 5, able to open inside said spacer rails lb, and, on either side of said windows 5, first slots 6, able to allow fixing said spacer rails lb via

  hooks 7 provided at the longitudinal end of said spacer rails 1b.

  Said windows 5 are, in particular, evenly spaced on the carrier rail la, according to the pitch defined by the mesh formed by the reinforcement

  according to the invention, or a multiple of said step.

  In this regard, in the case of the application of the invention to the false ceiling support, said armature further comprises, between said support rails 1a and / or between said spacer rails 1b, support rods 8, able to reduce the mesh size. Said support rods 8 thus make it possible to use slabs of smaller surfaces to constitute

said false ceiling.

  Said support rods 8 are, for example, fixed on said rails 1a, 1b at second slots 9, provided on their lateral flanks 4, by means of hooks secured to each of the ends.

said support rods 8.

  According to the embodiment shown, said spacer rails 1b and said support rods 8 cooperate with said rails

6 2752858

  carriers la, in particular, by clipping in their respective slots 6, 9.

  Referring now to FIG. 2, it can be seen that said support rods 8 share, for example, the squares defined by two carrying rails 1a and two spacer rails 1b contiguous into four equal squares and reduce the pitch of the mesh by two . By way of nonlimiting example, the armature according to the invention thus makes it possible to support slabs of 600 mm x 600 mm false ceilings,

  1,200 mm x 1,200 mm and / or in another configuration, 600 x 1,200 mm.

  Referring to FIGS. 3 to 7, it can be seen that the attachment means 3 are constituted for example by the internal profile of said internal cavity 2, in particular angularly designed, capable of cooperating with support means 10 of said distribution channels. fluid and / or said first elements of housing equipment. Said attachment means 3 are thus constituted, for example, by two shoulders 11, provided on the

  side flanks 4 of said rails 1, over the entire length of the latter.

  Said support means 10 can thus be secured to the inside of said rails 1, thanks, in particular, to said shoulders 11 and are equipped, for example, as shown in FIGS. 4 and 5, with an electrical pre-wiring 12, and / or allow the maintenance, as represented in FIG. 6, of first lighting means 13, and / or, as represented in FIG. 7, of water supply pipes 14 for fire protection and / or sheaths.

  More precisely, with reference to FIGS. 4 and 5, it can be seen that, according to the illustrated embodiment, the support means 10 consist, for example, of a block 16 provided with a five-wire pre-wiring. phases, forming, in particular, a female connector. Said block 16 is hooked, for example by clipping, at the holes provided on the upper sidewall

  said rails 1, thanks to a projection 17.

  According to FIG. 4, said block 16 is also hooked inside said rails 1 by means of two wings 18, allowing said block 16 to snap onto said shoulders 11. Moreover, according to this embodiment, said block 16 is provided with a pipe guide 19. Moreover, as illustrated in FIG. 6, said wings 18 can also be used,

possibly, cable guide.

  According to FIG. 5, in order to complete the pre-wiring, said female unit 16 is equipped, for example, with a male connector 20. Such pre-wiring makes it possible to obtain a good modularity of the electrical distribution. In fact, it is possible to provide, for example, female connectors 16, at the level of the spacer rails 1b supplied by means of male connectors 20 inserted into female connectors 16, provided at said carrying rails 1a, in the vicinity of their intersection, other connectors, powered by the first, being arranged at any point of said rails, lb. Said connectors along the same carrier rail are, for example, interconnected and connected to the sector,

  thanks to a terminal block provided at the end of said carrier rail la.

  According to the embodiment illustrated in FIG. 7, said support means 10 are also constituted, in particular, by two wings 21, snapped onto said shoulders 11, provided with a pipe guide 19 of profile similar to that previously encountered at the block 16 in order to

  allow the maintenance of said pipes 14.

  Referring back to FIG. 1, it can be seen that said rails 1a, 1b consist, in particular, of a body 23, defining a lower opening 24, and of a lid 25, able to close, at less

partially, said opening 24.

  Said body 23 is provided, at the level of the lower opening 24, on each of its lateral flanks 4 and all along the rail 1a, 1b, of returns 26, oriented towards the upper side of said rail 1a, 1b, so as to to permit

  the clipping of the cover 25, itself provided with corresponding flanges 27.

  According to the various exemplary embodiments, the covers are not necessarily provided along the entire length of the rails 1a, 1b or even on all of said rails 1a, 1b. Indeed, as developed further, they can be replaced, in particular, by grids for the passage of

8 2752858

  air conditioning and / or lighting distribution.

  In this regard, referring to FIG. 6, it can be seen that said first lighting means that can be accommodated in said internal cavity 2 consist, for example, of a support plate 28 hooked by clipping into said rail 1 at said returns 26 provided on the body 23 of said rails 1a, 1b. Said plates are provided, in particular, with a male connector 29, adapted to cooperate with the female connectors 16. Moreover, said

  plates 28 are equipped, for example, with fluorescent tubes 30.

  Said first lighting means 13 also comprise, for example, a clipped gate 50, as mentioned above, at

  level of the opening 24 of the body 23 of said rails 1.

  According to other embodiments not illlustrés, it should be noted that said internal cavity 2 could also accommodate, including, alarm devices, sound or other and / or could be used to

  The hanging of an internal partitioning of the building.

  That being the case, referring again to FIG. 1, it can be seen that said rails 1a, 1b are provided with hubcaps 31, able, on the one hand, to close said opening 24 at the crossing of said rails la, lb and / or, secondly, to constitute support means of second elements

  technical equipment of buildings.

  Said hubcaps 31 are constituted, for example, of synthetic material and have, in particular, a contour 32, adapted to snap onto said rails 1a, 1b and defining a light of a given diameter, as well as, optionally, a reducer 33, suitable to reduce the diameter of said light so as to allow the hanging of suspension rods

  said second means of technical equipment of buildings.

  When said hubcaps 31 are not so used, they

  further comprise a shutter 56 adapted to plug said lights.

  The hubcaps 31 have the advantage of reinforcing the stability of the reinforcement according to the invention and also participate in its

aesthetic appearance.

  By way of remark, the reinforcement according to the invention may also comprise, possibly, hubcaps 31, clipped onto the rails 1a, 1b in other places than at the intersections of the carrying rails 1a with the

  spacer rails lb, as illustrated in FIG.

  Said second interior equipment elements are constituted, for example, as represented in FIG. 8, by second means

  34, and / or as shown in FIG.

  fire such as, in particular, nozzles 35 of diffusion of water, smoke detectors or others. Said hubcaps 31 are also able, for example, to support shelves and / or columns of columns.

electrical distribution.

  Referring more specifically to FIG. 8, it can be seen that said second lighting means 34 consist, for example, of a fluorescent tube 36 and a deflector 37, fastened to the hubcaps 31 via the intermediary of FIG. two suspension rods 51. According to other embodiments, said fluorescent tube may also be provided, optionally

  at the internal cavity 2 of the rails 1.

  Said hubcaps 31 may also, possibly,

  accommodate recessed lamps and / or support adjustable spotlights.

  Referring now to FIG. 9, it can be seen that said air-conditioning ducts 15 can be received at the level of the

  internal cavity 2 are constituted, for example, by said rails 1 themselves.

  The air conditioning is then achieved, in particular, thanks to a light 38, provided on the upper side of said rails I allowing the hooking of the circuit 40 of air distribution of the building. The sealing of said air circulation is ensured for example, thanks to joints disposed at the ends of said rails 1 constituting the sheaths 15 and / or around said

lights 38.

  An airflow deflector 39 is provided, at the end of the air distribution circuit 40 of the building, in said cavity 2, so as to favor a good distribution of the flow of air inside the latter, according to the

2752858

arrows marked 52, 53.

  Said ducts 15 are provided, at the opening 24 of said rails 1, for example, with a grid 54, possibly equipped with a filter 55. Of course, for the sake of safety, each rail 1 will have a given function and It will thus avoid circulating by a

  same rail 1, several different fluids.

  Referring again to FIG. 3, it can be seen that said rails 1 have, for example, along their entire length, at their lateral flanks 4, a groove 41 capable of allowing the support of slabs 42 of false ceilings. Said groove has, for example, orthogonal flanks and allows, at the same time, internally define said shoulders 11 and, externally

to support said slabs 42.

  As a nonlimiting example, the section of said rails 1 is substantially in a rectangle, in particular of maximum dimensions of mm high x 100 mm wide and, for example, of 80 mm x 75 mm .. It is thus , able to accommodate the technical building equipment of size

  Reduced now available while providing a small footprint.

  All of its flanks form between them, for example

  right angles. Their thickness is, in particular, about 0.5 mm.

  As for the throat 41, it presents, for example, a

depth of about 7 mm.

  In the case of false ceiling tiles 42, said rails 1a, 1b are optionally covered with an insulating material in order to avoid the

formation of phonic bridges.

  Referring back to Figure 1, we see that they are subject to the ceiling of the room they equip, for example, with suspension brackets 43, including spring steel to allow clipping. In the same figure, it may be noted that the body 23 of said carrier rails la is provided, at the edges 44 of its lateral flanks 4 and 2752858 provided under said groove 41, with cutouts 45, adapted to cooperate with the corresponding edges 44 of the spacer rails 1b, said cutouts 45 having, locally, an enlargement, allowing the passage of the hubcaps 31 of said spacer rails 1b. As a remark, it can be seen that, according to the illustrated embodiment, said frame can be mounted entirely by clipping and

  therefore does not require the use of tools.

  An embodiment of armatures equipped with first means 13 and / or second lighting means 34 as well as air conditioning ducts 15, fire diffusion nozzles 35, lighting spots 46 and / or detectors of fumes 47 is given in FIG.
