Description

The present invention relates to a frame and a corresponding partition designed in particular to increase the fire resistance.

The present invention relates more particularly, but not exclusively, to the production of ceilings with increased fire resistance and the production of vertical insulating wall partitions of a wall.

The document EP-1 134 329 discloses a grid structure for supporting plaster panels or similar materials for use in the construction of false ceilings or false walls. This structure comprises main frame profiles, to be suspended from the ceiling or the wall to be covered, and auxiliary frame profiles, substantially C-shaped, coplanarly connected to said main frame in order to form with it a crossing arrangement. orthogonally. The main frame profile is also substantially C-shaped. It comprises a base and two flanks rising orthogonally from opposite sides of the base, the slots being formed in pairs in the base and said flanks. Each pair is adjusted for latching with a corresponding auxiliary frame profile as a result of a locking operation performed along a direction orthogonal to the plane of the structure, said flanks being substantially higher than the flanks of the frame profile. auxiliary.

The document US 4492066 also reveals a grid structure to be used in the construction of false ceilings. The disclosed structure comprises U-shaped elements and more particularly relates to connection means between these elements. The structure described in this document provides profiled elements that are all similar. Each profiled element is connected at one of its ends in the middle of another profiled element arranged perpendicularly to it.

The document EP-0 796 656 discloses a slide and a method for making a ceiling. Here, a bidirectional structure comprising on the one hand longitudinal C-profile rails and struts extending perpendicular to the longitudinal ralls is made. The spacers are hung on the longitudinal profiled rails by means of connecting pieces. Plates are then fixed, in particular by gluing, both on the longitudinal rails and the spacers. It is not intended in this document to achieve the ceiling using plasterboard, nor to achieve a vertical partition.

A ceiling made using plasterboard is fixed on a frame installed in the underside of a support structure such as a frame or a floor. This intermediate frame is generally made of metal profiles attached to the corresponding support structure using parts called hangers. The metal profiles are arranged longitudinally with a spacing generally of 0.6m.

Conventionally, to increase the fire resistance of such a ceiling, the distance between the profiles is reduced. It also reduces the screw spacing of the plates on the profiles. In addition, a plaster tongue is mounted between each section of the frame and the facing plates forming the ceiling. At the junction between two plates, when the junction line is parallel to the axis of the profiles, the frame is doubled. This means that instead of screwing each end of the plate on the same profile, it has two sections almost side by side and the junction plates is between the two profiles. Of course, at the level of these doubled profiles is also used plaster tongues,

Such an assembly is generally called fire assembly. We note that such an assembly is much more complex than a conventional assembly. The time required to make a fire fixture is much more important than for conventional mounting.

The problem at the origin of the present invention is initially to provide a frame that can be put in place more easily than the framework of a fire assembly of the prior art while ensuring the same fire resistance.

• des rails profilés longitudinaux présentant une face appelée fond servant de face d'appui à la plaque de parement correspondante ainsi que des faces latérales s'étendant longitudinalement le long du fond, de part et d'autre de celui-ci, et
• des moyens de liaison entre ces rails profilés et un support.

For this purpose, the invention proposes a frame intended to receive plasterboard facing plates, comprising:

• longitudinal profiled rails having a face called bottom forming a support face to the corresponding facing plate and side faces extending longitudinally along the bottom, on either side of it, and
• connecting means between these profiled rails and a support.

According to the invention, this frame further comprises spacers arranged transversely with respect to the longitudinal rails and each end of a spacer comprises first fastening means cooperating with second fastening means arranged at regular intervals at the side faces of the rails. longitudinal.

This framework allows for a rigid bidirectional framework on which can be fixed facing plates. Its rigidity makes it interesting to make a fire montage of a ceiling. However, it has also been found that a frame of this type could very well be used, with many advantages, for the realization of an insulating doubling of a wall.

Such a frame therefore has the advantage first of all to be able to use conventional profiled rails of the prior art, with just minor modifications, thus making it possible to be compatible with the existing elements. In addition, such a frame can be used for mounting a "classic" ceiling, a fire resistant mounting of a ceiling but also for the realization of a thermal doubling of a wall.

For better support of the spacers on the profiled rails, locking means are advantageously provided at one end of at least one spacer.

In a preferred embodiment, each spacer carries latching means while the second fastening means comprise complementary latching means. The latching means of the spacer is an embodiment of the locking means mentioned above. The complementary latching means may simply be a light for the passage of the latching means of the spacer.

Advantageously, the spacers have the same height as the profiled rails. In this case, the second fastening means on the profiled rails are preferably centered on the height of the corresponding lateral face and symmetrical with respect to the median longitudinal axis of said lateral face. In this way, the mounting of the spacer on the longitudinal rail is reversible: the spacer can be mounted in one direction or the other with respect to the longitudinal rail. This feature is advantageous for allowing the same spacers to be used both for the production of ceilings and partition walls. insulating lining.

A preferred embodiment provides that each spacer has a U-shaped shape with a base and two lateral flanks and that the base of the spacer is extended at the ends of the spacer by a cut tab and optionally folded and / or pressed to form the first fastening means.

In an alternative embodiment, each spacer has a U-shaped shape with a base and two lateral flanks, the base of the spacer is extended at the ends of the spacer by a cut tab and said tongue is for example cut and / or folded so as to form a tab intended to bear against the bottom of a longitudinal rail.

According to another embodiment of the invention, the first fastening means carried by a spacer comprise for example a substantially flat lug and parallel to the bottom of a longitudinal rail, the leg of which projects a clip; the second fastening means carried by the longitudinal rail comprise a slot in which can be introduced the tab and the clip, the latter being arranged to allow the insertion of the tab into the slot but to prohibit withdrawal of the tab out of the slot.

In another alternative embodiment of a frame according to the invention, the spacer has a transverse end plate bearing a stamp of size and shape adapted to the size and shape of an opening formed in a side wall. longitudinal profiled rail and forming the second fixing means. In this variant, locking means may be provided in that the stamping is in the form of a rib, and in that a cut is made at the base of the rib parallel to the plate on a portion of the length of the rib.

The present invention also relates to a ceiling, characterized in that it comprises a frame as described above as well as facing plates screwed to the bottom of the longitudinal profiled rails on the opposite side to the lateral faces of said rails. To allow the attachment of facing plates both on the bottom of the longitudinal rails and on the bases of the spacers, the bottom of the profiled rails are advantageously substantially in the same plane as the bases of the spacers for such a ceiling. The facing plates are then advantageously screwed into strut bases.

The present invention also relates to a partition, characterized in that it comprises a frame as described above as well as facing plates screwed to the bottom of longitudinal profiled rails on the opposite side to the lateral faces of said rails. In such a partition, the spacers have, for example, a U-shaped cross section with a base and two lateral flanks and are preferably mounted horizontally between the vertical profiled rails so that the bases of the spacers are arranged opposite the bottom of the channels. longitudinal rails. In this case, at least some spacers are preferably fixed on a support such as a wall or the like. The frame, that is to say both the spacers and the longitudinal profiled rails, is then perfectly fixed on the wall or the like. An embodiment of such a partition provides that the fixing of at least one spacer is provided by an anchor having a deformable tubular portion, and that the anchor extends perpendicular to the base of the spacer so that the deformable tubular part is located on both sides of the base. This embodiment allows a perfect hold of the spacer relative to the support on which the frame is fixed.

The figure 1 first represents a profiled rail 2. It is a rail such as those usually used to achieve a ceiling or partition frame, with slight modifications that will be explained later.

At the base, the profiled rail 2 of the figure 1 corresponds for example to a profiled rail type F530 marketed by PLACOPLATRE. In this case, it is a galvanized steel profile. This profile has a bottom 4, side faces 6 and in the preferred embodiment shown in FIG. figure 1 also edges 8.

The bottom 4 is substantially planar and is intended to serve as a support for a facing plate. It also receives fixing screws during the fixing of a facing plate on the frame.

The lateral faces are also substantially flat and extend on either side of the bottom 4, perpendicular to it. The flanges 8 are arranged at the free edge of the side faces 6 and extend towards each other substantially parallel to the bottom 4. These flanges 8 cooperate for example with a hanger foot to allow the fixing of the profiled rail 2 .

As can be seen on the figure 1 , the side faces 6 of the profiled rail 2 have fastening means arranged at regular intervals. In the embodiment of the figure 1 these fastening means are constituted by slots 10 of rectangular shape, elongate and narrow. These slots 10 are arranged longitudinally with respect to the lateral faces 6 and are each halfway up the corresponding lateral face 6. The lights 10 of a side face 6 each face a light 10 of the opposite side face 6.

These lights are for example machined on the production line of the profiled rail 2 after profiling thereof. The pitch between the lights 10 is for example 0.60m.

The figure 1 also represents a spacer 12. The overall shape of this spacer is that of a U-shaped piece with a base 14 and two side flanks 16. This spacer 12 is for example made of galvanized steel. The height of the spacer corresponds for example to the height of the profiled rail 2. The length of the spacer depends on the distance to separate two longitudinal rails 2 of the frame to achieve. The length of this spacer will correspond to the value of the pitch of the longitudinal rails 2 less the width of a rail. Thus, using, for example, longitudinal rails 2 of the F530 type, to make a frame with longitudinal rails 2 arranged at a pitch of 0.60m, the length of the spacers will be 0.55m. This spacer length corresponds to the length of the side flanks 16. For longitudinal rails arranged at a pitch of 0.50m, the length of the spacers 12 will be 0.45m.

Note that at each of its ends, the spacer 12 carries fixing means. These are made by folding and cutting an extension of the bottom 14 of the profiled portion of the spacer 12. The present description proposes several embodiments of these fastening means. These are represented in more detail on the Figures 2 to 19 . The embodiment shown on the figure 1 is a simplified form of the embodiments of Figures 2 and 3 .

In a preferred embodiment, a frame according to the invention comprises longitudinal rails 2 arranged parallel to each other at a predetermined pitch, for example 0.50m or 0.60m. These rails are connected by spacers 12 extending perpendicular to the profiled rails 2. These spacers are fixed at both ends to the rails they connect.

The longitudinal rails are for example in a horizontal plane to achieve a ceiling or possibly in a vertical plane to achieve a partition. In the case of a ceiling, the longitudinal rails 2 can be fixed in a known manner on the underside of a floor using hangers known to those skilled in the art. It is also possible to use profiled rails for the edge slides (not shown) known to those skilled in the art. These are, for example, edge slides of PLACOPLATRE sold under the name STIL ^® F530. These edge slides are optionally adapted to the chosen pitch.

The establishment of a framework according to the invention is very close to that of a conventional framework. Indeed, the longitudinal rails 2 are mounted in a conventional manner, at the desired pitch. It is only necessary to ensure that the fastening means of two adjacent profiled rails 2 are aligned. Then, spacers are put in place between the profiled rails. Preferably, these spacers 12 are simply snapped onto the longitudinal rails 2 of the frame. Depending on the characteristics of the ceiling or the partition that one wishes to make, one can then use spacers for example every 0.60m or every 1.2m or even without spacer for a "conventional" mounting.

Such a framework can also be advantageously used for producing an insulating lining, for example expanded polystyrene, both in new buildings and for the renovation of existing buildings.

In a preferred embodiment, the thermal insulation is provided by expanded polystyrene elements or by expanded and elasticized polystyrene elements. With a framework according to the invention, the characteristics of the polystyrene can be adapted to the real needs for the insulation because, as it follows from what follows, the insulating elements used have no mechanical function, unlike the use for example glued doublings. All thicknesses of insulation can be considered. It is also possible to provide flat elements or grooved elements for the passage of pipes. It can be floor boards with straight edges or longitudinal edges assembled by tenons and mortises, or tiles assembled by tenons and mortises on all four sides.

The insulators are held on the support wall by simple bonding (mortar or putty) on a finished slab or on a bare floor.

The framework is a framework as described above. It has longitudinal rails arranged vertically and spacers arranged horizontally. High and low slides are advantageously used to facilitate the installation of the longitudinal rails. They are maintained on the floor and under the floor by mechanical fasteners.

The longitudinal rails, vertical, are then nested and arranged for example at a step of 0.6m between the scenes by providing at the head a game of the order of 10mm.

A first line of spacers is preferably arranged at a height of 1.30m from the ground. Here, the spacers are fixed so that the base of each spacer is disposed on the side of the insulators. Unlike the mounting of a ceiling, the bases of the spacers are therefore not in the same plane as the bottom of the longitudinal rails. Other lines of spacers can then be put in place.

The spacers are then drilled, for example in their center, and can be pegged through the hole made on the support wall. Through the pins and spacers, the entire frame, and thus also the vertical longitudinal rails for receiving the facing plates, is securely fixed to the support wall.

When openings are provided in the wall, which is often the case, it is also possible to use metal plates arranged in line with the lights of the vertical framework profiles intended to receive the intersected spacers to the right of joinery and / or re-entrant angles or outgoing.

Metal connecting brackets for securing vertical structural sections can also be used to the right of the incoming and outgoing angles.

On the figure 2 a section of the connection between a profiled rail 2 and a spacer 12 is shown schematically. The profiled rail 2 is cut transversely while the spacer 12 is cut longitudinally.

We recognize on the figure 2 the bottom 4 of the profiled rail, a side face 6 and the corresponding flange 8. The cut is made at a light 10. On the side of the spacer 12, the base 14 is recognized and a side flank 16 thereof. The spacer 12 further comprises two support lugs 18, an arm 20 and a latching lug 22 carrying a clip 24. All these elements are obtained by cutting and folding a tongue which initially extends the base 14 of the spacer 12.

The support lugs 18 are arranged laterally and extend in the plane of the base 14. They are on the side of the side flanks 16 and the arm 20 with its latching lug 22 is between the two support lugs. 18.

The latching lug 22 is intended to cooperate with the light 10 of the profiled rail 2. The dimensions of the light 10 are therefore adapted to the dimensions of the latching lug 22 and vice versa. The dimensions of the arm 20 are also adapted. The length of the arm 20 thus substantially corresponds to the distance separating the light 10 from the bottom 4 (to the sheet thicknesses close). The latching lug 22 is mounted substantially at right angles to the arm 20. The latter is folded relative to the base 14 so as to be pivotable relative thereto, driving with it the leg of snapping 22.

The latching lug 22 carries a clip 24. The latter protrudes above the latching tab 22. It is elastically connected thereto. Conventionally, the shape of this clip is substantially rectangular and the clip 24 is obtained by cutting into the latching tab 22. Three sides of the clips 24 are cut while the fourth side, the closest to the free end of the latching lug 22 corresponds to a fold line. In this way, as illustrated in the drawings, the latching lug 22 can easily be introduced into the light 10. In a manner known to those skilled in the art, during the passage of the tab in the light 10, the clip 24 folds to be substantially in the plane of the latching lug 22 and resumes its protruding position above the latching lug 22 once it has passed through the light 10. It then forms a stop preventing the latching lug. involuntary withdrawal of the leg latching 22 out of the light 10.

The characteristics described above are found on the embodiment of the fastening means of the figure 1 . With respect to this embodiment, the figure 2 further provides an actuating knob 26 and an opening 28 in the base 14 of the spacer 12.

The actuating button 26 is disposed on the arm 20 on the inside of the spacer 12. The opening 28 is in turn made in the base 14 of the spacer 12 near the arm 20. This opening 28 serves as access to the arm 20 and its actuating button 26. Indeed, in this embodiment, in the rest position, the arm 20 is folded towards the inside of the spacer 12. To make a snap, it is then necessary to push the latching lug 22 into the light 10 as suggested by the arrow represented on the figure 2 . During the placement of the spacers 12 between the longitudinal rails 2, it acts through the opening 28, via the actuating button 26 on the arm 20, and thus on the latching lug 22, to pass the clip 24 entirely through the corresponding opening 10.

The figure 3 shows an alternative embodiment of the figure 2 . Here, the actuating button 26 is replaced by a lug 30. While the actuating button 26 is more particularly adapted to be actuated with the aid of a finger, the lug 30 is rather adapted to be actuated with the end of the blade of a screwdriver.

The variant embodiment of the Figures 4 and 5 is a simplified variant. There is no provision for a support leg. In addition, there is no member for acting on the arm 20 or opening in the base 14 of the spacer 12. The shape of the clip 24 is slightly different from the form described above. Indeed, the clip is here circular and a convex shape has been given. As can be seen in particular on the figure 5 , the clip 24 is cut on almost all of its periphery except on a small circular arc near the free edge of the latching lug 22, opposite the arm 20. In addition, at rest, the arm 20 is inclined towards the outside of the spacer 12, that is to say towards a possible profiled rail 2. By setting up this spacer 12 against a profiled rail 2, insofar as the latching lug 22 is facing a light 10, the snap of the spacer 12 on the profiled rail 2 is automatically realized. It is therefore unnecessary a priori to provide an opening in the base 14 of the spacer close to the arm 20.

The embodiment of the Figures 6 and 7 is very close to that of Figures 2 and 3 . The difference is here at the arm 20. This arm 20 has no actuating button 26 or lug 30. It has against a hole 32 for example for the passage of a screw for fixing the spacer 12 on the longitudinal rail 2.

The Figures 8 and 9 present a modified embodiment with respect to the embodiment of Figures 6 and 7 . This variant embodiment makes it possible to easily separate the spacer 12 from the longitudinal rail 2 on which it is mounted. For this purpose, a lever 34 is associated with the clips 24. This lever 34 is in one piece with the clips 24. This piece is obtained by cutting and folding in the latching lug 22 and the arm 20. The lever 34 extends towards the spacer. Once the spacer 12 mounted on a profiled rail 2, the lever 34 protrudes inside the spacer 12. It is then sufficient to press the lever 34 towards the base 14 to remove the bracket. snap 22 out of the corresponding light 10. Note here that in this case the size of the light 10 is greater than that of the lights for the embodiments described above.

The Figures 10 to 12 represent another embodiment of means for fixing a spacer 12 on a profiled rail 2 of a frame according to the invention. In this embodiment, there is a central support lug 18 and an arm 20 of substantially greater size than the arms 20 of the other embodiments. Here, the arm 20 extends over the entire height of a lateral face 6 of a profile rail 2. It further comprises at its free end a hooking flange 36. In front view ( figure 12 ) the arm 20 has an overall rectangular shape, almost square, having a rectangular opening on the side of the base 14 and centered between the two lateral flanks 16. This opening, obtained for example by cutting, corresponds to the support lug 18 and to the latching lug 22. Whereas in the other embodiments of the Figures 1 to 9 the latching lug was the extension of the arm 20, the latching lug 22 is here cut in the arm 20. This does not change its operation. There is also a clip 24 protruding from the latching lug 22.

The Figures 10 and 11 represent the spacer respectively before and after fixation on the profiled rail 2. In the rest position, the arm 20 is inclined towards the inside of the spacer 12 after installation, the operator acts on the arm As suggested by the arrow on the figure 10 to pass the latching lug 22 through the corresponding slot 10 of the profile rail 2 until latching. Once snapped, the spacer 12 is then perfectly fixed on the longitudinal rail 2. With the support lug 18 and the hooking flange 36 no movement perpendicular to the plane of the base 14 is possible and the leg of the snap 22 with its clips 24 ensures locking in this position by preventing longitudinal movement.

In the embodiment of the Figures 13 to 15 , found at the side faces 6 of the profiled rail 2 a rectangular light 10.

The end of the spacer 12 of Figures 13 and 15 is closed by a plate 38. The latter forms a single piece with the base 14 of the spacer 12. It is folded at right angles to the end of the side flanks 16 and comes to rest against the corresponding edges of these- this. A flange 40 is covered on each side of the ends of the side flanks 16 of the spacer 12. In the center of the plate 38, a stamping is performed. This stamping forms a rib 42 projecting towards the outside of the spacer 12. To allow the realization of this stamping, a cutout 44 is made at each end of the rib 42. The latter extends parallel to the base 14 , at mid-height of the side flanks 16. Its dimensions correspond to the dimensions of the light 10 of the profiled rail 2 of the figure 14 .

As we see best on the figure 15 , spacer 12 of Figures 13 and 15 also comprises a hooking flange 36. The latter is intended to bear on the flange 8 corresponding to the profiled rail 2.

The variant embodiment of the Figures 16 and 17 differs from the embodiment of the Figures 13 to 15 by the shape of the stamping and by the presence of support lugs 18. The stamping of this new embodiment is here a circular puncture 46. The light (not shown) made in a side face 6 of a rail section 2 has a corresponding circular shape.

The bearing lugs 18 are, as for the variant embodiments concerned described above, intended to come against the bottom 4 of the profiled rail 2. These bearing lugs 18 are obtained here by a cut made in the base 14 of the spacer 12 and by folding 180 ° from the outside of the spacer.

The Figures 18 and 19 show another alternative embodiment of the embodiment of Figures 13 to 15 . This variant concerns locking of the spacer 12 on the profiled rail 2, and in particular the rib 42.

This new variant of embodiment incorporates the various elements of the variant of the Figures 13 to 15 . There is thus a rectangular light in the section 2. At the spacer 12, there is a rib 42 formed on a plate 38 closing one end of the spacer 12. The rib 42 is projecting outwardly of the spacer and is intended to cooperate with the rectangular light of the profiled rail 2. With respect to the rib 42 of the Figures 13 and 15 , rib 42 of the Figures 18 and 19 has a cutout 48. The latter is made parallel to the plate 38 at the base of the rib 42. It extends over a portion of the length of the rib, for example a portion representing between one third and one half of the rib. length of the rib 42.

The figure 18 represents the spacer 12 facing the profiled rail 2. A double arrow 50 illustrates the movements to be carried out to assemble firstly the spacer 12 and the profiled rail 2 and to lock on the other hand these two elements. In a first movement, transverse to the profiled rail 2, the rib 42 is inserted into the corresponding slot 10. The cut 48 of the rib 42 is then at a lateral face 6 of the profiled rail 2. The rib 42 is then slid with the spacer 12 longitudinally relative to the profiled rail 2 so that the rib 42 comes to overlap the lateral face at the level of the cutout 48. The spacer 12 is thus locked on the profiled rail 2.

On the figure 19 partially shown two facing plates 52 fixed to the frame members assembled in the case of a ceiling. These facing plates 52 are screwed firstly to the bottom 4 of the profiled rail 2 and secondly to the base 14 of the spacer 12. Lines 54 in phantom are schematically the screw locations used for fixing The latter are, relative to the bottom 4 of the profiled rail 2, the opposite side to the side faces 6. The profiled rail 2 here carries the facing plates 52 as in a conventional assembly of the prior art but it is helped here in its function of supporting plates by the spacers 12.

As can be seen, stampings made in the embodiments of Figures 13 to 19 are not mounted on an elastic leg but on a fixed plate. When mounting a spacer 12 between two profiled rails 2, the stamp 42 or 46 bears on a lateral face 6 of a profiled rail 2 and this lateral face deforms elastically until the introduction of this stamped into the corresponding light. Once stamped in place, the side face returns to its original undistorted position.

These various embodiments allow easy mounting of a spacer 12 on a profiled rail. The spacers 12 described above can be used with almost standard profile rails. One can very well consider that all the profiled rails, they are intended to be mounted with or without spacer, include lights for the mounting of spacers. These lights do not change the lift capacity of the profile rail.

The system proposed above allows for a bidirectional frame as simple to mount a frame having only rails extending in a single direction. Indeed, it is not necessary to provide tracing operations for the implementation of the spacer lines. The lights in the profile rails immediately determine the position of the spacers. Nor is it necessary to provide adjustment operations for the alignment of the strut lines.

When a framework as described above is implemented for the realization of a ceiling (as shown in FIG. figure 19 ), the base 14 of the spacers 12 is substantially in the same plane as the bottom 4 of the profiled rails 2. The facing plates can then be fixed on both the profiled rails 2 and the spacers 12. The profiled rails 2 are attached to a support using, for example, lines. It may be noted here that the spacers 12 can be located at the right of a hanger. Thus during the realization of the frame, it is not necessarily necessary to pay attention to the relative position of the spacers with the lines.

For the realization of a partition (as illustrated on the figure 20 ), the spacers 12 are advantageously mounted so that their bases 14 are opposite the bottom 4 of the profiled rails 2. The frame is then fixed using the bases 14 of the spacers 12 on a support while the bottoms 4 of the profiled rails 2 are used to receive the facing plates.

The Figures 21A and 21B illustrate means that can be implemented for fixing a partition frame according to the invention on a support. The latter is for example a wall already existing when performing a partition doubling.

The figure 21A illustrates a peg 56 used as a fastening means before screwing a screw 58 into it completely. This peg 56 conventionally has an expansive portion 60. In a more original manner, the peg 56 has, on the opposite side to the expansive portion 60, a tubular portion 62 elastically deformable. This tubular portion 62 is intended to be traversed by the screw 58 and to be compressed during the tightening of this screw.

The figure 21B illustrates the peg 56 when the screw 58 has been tightened. The expansive portion 60 is deformed in a conventional manner and this deformed portion is not shown here. During the implementation of the pin 56, the tubular portion 62, made for example of rubber or equivalent, is disposed at the height of the base 14 of the spacer 12 to be maintained so as to extend from both sides. other of this base 14 (the pin 56 extends perpendicular to the base 14 of the spacer 12). When the screw 58 is tightened, it causes in parallel the deformation of the expansive portion 60 and the tubular portion 62. The latter is compressed and deformed to form on each side of the base 14 of the spacer 12 a bead shaped of barrel. The base 14 is then perfectly maintained with respect to the peg 56, itself firmly anchored in the support thanks to the expansive part 60. Once the fixing of the spacer 12 on the corresponding support is made, a facing plate 52 can be attached to the profile rails 2 as shown on the figure 21B . The head of the screw 58 and a portion of the pin 56 are fully housed in the spacer 12, between the side flanks 16 thereof.

The frame thus produced is intended to receive facing plates, including plasterboard. By fixing these plates (cf. Fig. 19 ) on both the profiled rails and spacers in the case of the realization of a ceiling, it removes the risk of sagging plates due to humidification of the structure. Fixing the plates both in two directions according to a grid also limits the buckling and deformation of the carrier lines in case of fire. Always in case of fire, the maintenance of the plates both on the longitudinal rails and on the spacers makes it possible to suppress the festooning of the plates due to the carbonization of the facings.

For mounting said fire assembly, it is unnecessary to provide at the transverse joints a doubling of the profiled rails. The assembly is therefore considerably simplified. Even when using standard plates and not no plates having increased fire resistance, the fire behavior of the ceiling or partition is substantially improved.

The presence of the spacers and the fixing of the facing plates on these allow to eliminate the stresses exerted on the plates due to the weight of the insulators in the case of an isolated ceiling.

In all the embodiments shown in the drawings, the spacers have a large mechanical strength which allows in one case (ceiling) to reliably support facing plates and in another case (partition) to securely fix the frame made to a support, like a wall.

A frame according to the invention also allows fixing by simply screwing the partition heads, whatever their location. It has also been noted that a frame according to the invention makes it possible to ensure better behavior of a ceiling in the event of an earthquake, that is to say when horizontal accelerations are observed. The use of spacers in a frame according to the invention also avoids the bracing suspension devices that are sometimes used to resist earthquakes.

A non-negligible advantage already mentioned above is also that the frame according to the invention can be compatible with existing systems currently.

In the case of using a frame according to the invention to produce an insulating vertical partition, many advantages can also be obtained through the use of a frame according to the invention.

Compared to performing a dubbing of the prior art, the invention allows a better coordination and organization of the interventions performed on the site. It also facilitates the qualitative and functional controls, improve the implementation of the insulation and the mechanical strength of the facing plates mounted on the frame.

As already indicated, all types of insulators can be used and in many forms. This insulation can also be set up either by the company responsible for the structural work, or by the plaquiste company or any other stakeholder, for example the electrician or the plumber when laying pipes.

Thus, a visual control of the continuity of the thermal insulation and the airtightness to the right of joinery, the installation, the control of the electrical conduits and hydro-wired networks can be made before the installation of the frame and must be carried out before the installation of the facing plates.

The fact of providing a line of spacers at 1.30m from the ground considerably improves the mechanical strength of the facing, especially with regard to the soft body impact behavior at 120 Joules.

The present invention is not limited to the various embodiments described above by way of non-limiting examples. It also relates to all the variants within the scope of those skilled in the art within the scope of the claims below.
