Description

 The present invention relates to a removable wall system or removable double wall.

 The present invention also relates to a method for forming such a partition.

 This type of partition is intended for example to achieve variable partitions in industrial or commercial premises.

 According to the invention, the removable or double-walled partition system for positioning by means of profiled elements two walls constituted by individual panels, so that these walls are spaced apart from each other by a distance predetermined, is characterized in that the profiled elements comprise a lower rail and an upper rail each having longitudinal grooves for positioning a horizontal edge of the panels, connection profiles, used as amounts, and whose ends are adapted to positioned in the lower and respectively upper rails and which comprise bracing means for maintaining said predetermined distance between the edges of the panels belonging to the two walls, the system further comprising locking means for removably holding the vertical edges of the panels in support against means of bridging.

 Advantageously, the connecting profiles comprise, for each wall, a gutter interposed in service between two successive panels of the wall, and the locking means comprise clips capable of resiliently locking in the gutters in a position where at least one wing the clip overlaps the outer face of one of the panels, and the system further comprises closures engageable in the gutters in a position where they hide the clips.

 Preferably, the cover snaps into the clips in a manner that both restrains it and prevents the clips from compressing sufficiently to escape the gutter.

 It is also preferable to have clips which on each wall overlap only one of the panels adjacent to the connection profile considered.

Such clips allow to lock the first panel placed, while leaving the way for the mounting of the other panel of the same wall, after which the other panel is locked with other clips from the overlap.

We do not have to wait for the two panels to be mounted in order to perform the locking.

 Joint covers can only be put in place at the end of the construction site, which avoids exposing them to damage.

 All of these technical effects and advantages are not obtained with some known systems in which the joint covers provide locking.

 To associate the amounts to the rails, is preferably placed at each end of a post a sliding bracket that makes up for the deviations in length from the nominal dimension. The wing of the brackets which is associable with the rails is shaped to be able to engage by fractional turn type movement under sliding ribs provided on the rail between the grooves for the panels.

 The same mounting principle can be used to arrange between successive amounts of sleepers that can be constituted by said connecting profiles when there is a succession of panels or glazings in the direction of the height, or by bracing profiles when it is simply a matter of restricting the bending possibilities of a high-rise sign.

 According to another aspect of the invention, the method for forming a demountable or removable partition using the system according to the first aspect, in which method is fixed to the ground a lower rail, is fixed to the ceiling an upper rail, and placed a succession of panels and uprights-between the lower and upper rails, is.characterized in that by a rotation of the upright around its longitudinal axis, engagement means are provided provided at at least one of the ends of-upright in means for sliding the rails, and then sliding the amount in the rails to the desired position.

 This method can be implemented by using as fastening means provided at the ends of the upright the brackets specified above.

 Other features and advantages of the invention will emerge from the following description.

 As shown in FIG. 1, the system according to the invention is intended to constitute a floor 1 and a ceiling 2 of a room a partition 3 comprising two walls 4.Each wall 4 comprises, in turn, panels 6, for example in plaster. The panels 6 are retained by a removable frame which will now be described.

 The frame comprises a fixed lower rail 7, for example glued in service to the ground 1 and a fixed upper rail 8, for example glued in service to the ceiling 2. The rails 7 and 8 are constituted by sections of identical profiles.

 As also shown in Figure 3, the rail 7 comprises two outer side wings 9 each of which defines with a bottom 11 and an inner flange 12 a groove 13 for receiving a horizontal edge of one of the panels 6. The grooves 13 of the rail 7 open towards the ceiling 2 and those of the rail 8 open towards the ground 1.

 The inner wings 12 define between them a housing 14 in which, in use, a sealing strip 16, for example made of foam, is inserted between the floor 1 or the ceiling 2 respectively, and a web 17 of the rail which extends between the two wings 12.

 At their free end, the inner wings 12 are bent towards each other to each form a retaining fin 18 forming with the face of the core 17 opposite the housing 14 a slide whose role will be explained later.

 As shown in Figure 4, the frame of the partition according to the invention further comprises connecting profiles 20 used in particular as amounts between the successive pairs of parallel panels. Each connecting section comprises a central web or core 19 connecting one to the other two gutters generally U-shaped 21, opening outwardly of the partition. Each gutter 21 is in use interposed between two successive panels 6 of the same wall 4. Each gutter 21 carries, on each side of the veil 19, a bracing wing 22 intended to rest on the inner face of one of the panels 6.

Thus, on each side of the web 19, two wings 22 define between them a predetermined minimum distance between the two parallel panels 6 adjacent thereto.

 The gutters 21 still each carry, and on each side of the veil 19, a retaining fin 31. Each pair of fins 31 located opposite one another forms with the veil 19 a slide. There is therefore such a slide on either side of the web 19 of each connecting section.

 The opening of each channel 21 is narrowed by two ribs 23. These ribs 23 are intended to retain, by elastic locking, clips 24, one of which is shown in detail in FIG.

 The clip 24 consists of a profiled spring steel blade to have a loop-shaped body 26 terminated, on either side of a groove 27, by a long wing 28 and a short wing 29.

 In use, the body 26 is engaged behind the ribs 23, which define between them a free distance less than the diameter of the body 26 in the relaxed state.

The wings 28 and 29 remain outside the groove 21.

The short wing 29 does not protrude laterally from the gutter 21. On the contrary, the long wing 28 overlaps one of the two panels 6 adjacent to the gutter 21.

 The profiled elements that can be used to produce the framework of the partition according to the invention further comprise seal covers 32 intended to mask the gutter 21 and the clips 24 towards the outside of the partition.

 Each cover 32 comprises a mask 33 whose longitudinal edges are provided with flanges 34 for resting on the panels 6 beyond the long wings 28 of the clips 24. Each cover 32 further comprises a wing of locking 36 which extends along the median longitudinal plane of the mask 33 and carries at its end a bead 37.

 In use, it forces the bead 37 to pass through the groove 27 of the clip 24, so that the bead 37 is inside the body 26. The transverse dimension of the bead 37 being greater than the free width of the groove 27 when the clip 24 is in place in a channel 21, the cover 32 is thus locked in place, and this removably since the clip is elastic. At the same time, the thickness of the locking flange 36 below the bead 37 is such that, when the seal cover 32 is in place, the groove 27 can not tighten sufficiently for the body 26 of the clip 24 can pass between the stopping ribs 23.

Thus, the cover 32 locks the.clip 24 inside the gutter 21.

 The range of profiles according to the invention further comprises joint covers 38 comprising a mask 33 identical to that of the joint covers 32 and two locking wings 39 parallel to each other and each of which carries on its face opposed to the other, a rib 41 allowing it to snap behind a respective one of the ribs 23 of the gutter 21.

 The covers 38 are used when desired; for the sake of simplification, without clips 24 and their advantages which will be detailed later.

 In Figure 5, there is, for illustrative purposes, shown the two types of joint covers on the same partition. In practice, the same arrangement is used on both sides of the partition.

 The device according to the invention further comprises brackets 42 (FIGS. 6 to 9) each comprising a long wing 43 and a short wing 44. Each of the wings 43 and 44 bears along its edges perpendicular to the line 46 of folding. at 900 against the bent sliding edges 47 and 47a respectively.

Thanks to these edges, the long flange 43 of each bracket can be slidably engaged in the slide formed by the retaining fins 31 of a connecting section 20.

The short wing 44 of each bracket 42 can be slidably engaged, by its bent edges 47a, in the slide formed by retaining fins 83 each terminating one of the spacer wings 22. (This commitment is shown dotted line in Figure 4), or in the slide formed by the retaining fins 18 of the rails 7 and 8 (Figure 3). The spacing between fins 18 and between fins 83 is greater than the spacing between fins 31, and short wing 44 is wider than long wing 43.

 With respect to the general plane of the long wing 43, the sliding edges 47, due to their counter-welding, are offset on the side of the short wing 44.

 On the other hand, with respect to the general plane of the short wing 44, the sliding edges 47a of the short wing 44 are counter-bent on the opposite side to the long wing 43. The end of each bent edge 47a short wing 44 has an arcuate contour. The arcuate contours of the two edges 47a of the wing 44 belong to the same virtual circle 48.

 The short wing 44 is traversed by a central threaded hole 49 of axis perpendicular to its general plane. In the vicinity of its end, the long flange 43 is traversed by a tapped hole 51 of axis perpendicular to its general plane. The long wing 43, still has, below its tapped hole 51, a fold 52, through which is made a threaded hole 53 whose axis 54 is inclined in the plane perpendicular to the fold line 46. The edges against -bent 47 of the wing 43, and the fold 52 are located on either side of the general plane of the wing 43. Beyond the tapped hole 51, the wing 43 is terminated by a lug 56 on the same side of the general plan that the withdrawal 52.

 We will now describe the method of implementation of the partition according to the invention.

 In FIG. 10, it is assumed that the lower rail 7 and the upper rail 8 have already been fixed to the floor 1 and to the ceiling 2, for example by means of screws.

 An already assembled portion of the partition is terminated by a post 20 which has been put in place in a manner to be described later.

 The two panels 6 adjacent to this profile 20 (the panel 6 visible to the left of Figure 10 and the one located behind, belonging to the other wall) are retained by clips 24 whose long flange is directed towards the Partition already completed.

 Still as shown in FIG. 10, another panel 6 is then put in place. For the sake of clarity, this panel will be considered to belong to the wall that is furthest away from the observer of FIG. 10.

 Each panel 6 has a height greater than the free height between the outer lateral wings 9 of the rails 7 and 8. However, it is possible to engage the panel 6 between the rails 7 and 8 by bending the panel.

 As shown in Figure 1, the lower edge of the panel rests in its groove 13, where it is clamped between the wings 9 and 12 which converge downwards.

The upper edge of the panel 6 rests on a band of foam 62 contributing, with the band 16, the sound insulation.

 The narrowing of the grooves 13 towards their bottom 11 eliminates the lateral play of the panels 6 in their groove bottom. In addition, this establishes between the panel 6 and the adjoining wing 9 a clearance i corresponding approximately to the overall thickness of the covers 32 or 38.

The utility of this feature will appear later.

 In the rail 8, U-shaped spacers 63 have been snapped in far away under the retaining fins 18, so that even if the panels 6 have a height which is slightly insufficient to reach the grooves 13 of the upper rail 8, they are nevertheless held each between the spacers 63 and a wing 9.

 The spacers are more advantageous than an offset of the core 17 towards the plane of the ends of the wings 9. Indeed, such an offset would result in higher material costs (aluminum, foam for the band 16) and a need greater accuracy on the length of the uprights 20.

 As shown in Figure 13, is placed another profile 20 (that of Figure 13). For this purpose, a profile 20 of length greater than the free height between the lateral flanges 9 and the rails 7 and 8 was used. The long flange 43 (FIG. 2) was slidably engaged at each end of the section 20. a bracket 42, by putting the two brackets 42 of the same side of the web 19 of the profile 20. Given the presence of the tab 56 and the fold 52, and relative positions discussed in detail above with respect to the general plan of the long wing 43, the short wing 44 is necessarily oriented so as to cap the adjacent end of the sail 19, that is to point to the side of the sail 19 which is opposite to the long wing 43 Thus, the center of the virtual circle 48 in which the short wing 44 fits is not far from the axis of symmetry of the section 20.

 The profile 20 is thus equipped with its two brackets 42, it is inclined slightly in the plane of the wall to be made, to engage the profile 20 between the side wings 9 of each of the rails 7 and 8 and then it is raised, placing the veil 19 substantially parallel to the plane of the partition to be made. The short flange 44 of each bracket 42 is thus engaged between the free ends of the retaining fins 18 of the rail 7 or 8. To carry out this operation, the thumb is placed against the flap 56 of each bracket 42, in particular the upper one. , to push the brackets between the fins 18.

 Then, as shown in Figure 2, the profile 20 is pivoted, equipped with its two brackets 42, about its axis of symmetry, while the short wings 44 of the two brackets, driven by this movement, engage under the retaining wings 18 of the adjacent rail 7 or 8. During this movement, the raised part of the wing 44, that is to say the part situated below the bent edges 47a, penetrates partially under the retaining fins 18, whose spacing relative to the core 17 is provided for this. At the end of the movement, when the web 19 is perpendicular to the plane of the partition to be made, only the edges 47a are still under the retaining fins 18.

 Then, the amount 20 is slid between the rails 7 and 8 until one of the gutters 21 comes to bear against the panel 6 already in place.

 At this stage, as shown in FIG. 11, a screw 58 bearing on the vane 19 of the section 20 is screwed into the oblique twist 53 of each bracket 42. This screwing draws the two brackets towards each other. and puts the section 20 under mechanical tension. Moreover, because of this screwing, the raised part of the short wing 44, that is to say the boss portion between the contra-wedged edges 47a engages between the free ends of the retaining fins 18, as shown in FIG. Figure 12, which angularly positions the section 20 about its axis. During this power up, one adjusts the height position of the profile 20-par, relative to its two brackets, so in particular that each of its ends is concealed between the two outer lateral wings 9 of the corresponding rail 7 or 8 .

 The width of the profile 20, measured perpendicularly to the plane of the partition to be made, is slightly less than the free width between the lateral flanges 9 of the rails 7 and 8 so as to allow the rotation of the profile 20 around its axis during assembly, as just described.

 The mounting method which has just been described for the rail 20 of the straight line of FIG. 13 also applies to the profile 20 of the left of FIG. 13, whereas only one of the two parallel panels 6 of the left of FIG. Figure 13 was in place.

 Then placed on each of the two sections 20 located on either side of the panel 6 which has just been mounted, two brackets 42. For this, it engages the short wing 44 of each of these brackets by rotation in the slide constituted by two of the fins 83 of the corresponding section 20. Each bracket 42 is placed on the side of the star 19 which is turned towards the other profile 20. These brackets are fixed in height by means of screws 61 (FIGS. 1 and 4) which are engaged in the threaded hole 49 for that their end rests on the veil 19, so as to tighten the edges 47a against the fins 83.

 The long wing 43 of each of these brackets 42 is then attached to one of the ends of a crossmember 64 that can be seen in detail in FIG. 1. Each crossmember 64 is substantially shorter than the distance between the slides defined by the fins. 83 of the two sections 20, the difference being compensated by the length of wings 43 brackets 42. This avoids all problems that would be related to precise tolerances.

 The outer faces of the free wings of each crossbar 64, which is U-shaped, define between them the desired distance between the panels 6 of the two walls 4. Not shown, the central region of the U has in the vicinity of the ends of the sleepers 64 elongated holes through which can pass a screw 66 (Figure 1) screwing into the threaded hole 51 of the bracket 42 corresponding.

 Then, as shown in Figure 14, is placed the second panel 6 to be mounted between the rails 7 and 8 and between the two sections 20 considered until now.

With the tightening of the screw 61, the raised portion of the short wing 44 of each bracket 42 is positioned between the retaining fins 83, which prevents the cross members 64 pivot in an incorrect position about their axis when setting In place of the panel 6. Once the panel 6 in place, it is locked with clips 24 whose wing 28 is this time directed towards the panel 6 newly installed. It should be noted that the spacers 63 are optional when using the sleepers 64.

 In the example shown in Figure 14, it is expected that the next section of the partition has a bay 67 to be glazed. For this, we have sections of profiles 68 identical to the profiles 20, except their length which corresponds, with a good enough accuracy, to; <width of the bay to achieve. The ends of the profiles 68 are fixed to two successive uprights 20, then the upright 20 lastly placed in the rails 7 and 8 is locked. Under the lower profile 68, two parallel closing panels of partial height 69 are mounted, and likewise above the upper profile 68.

The engagement of these panels 69 in the rails 7 and 8 does not pose any particular problem since each of them must be engaged in only one of the two rails. The partial panels are immobilized by means of clips 24 engaged in the uprights 20 and in the crosspieces 68.

 Then, as shown in FIG. 15, a stick 71 having a U-shaped profile which overlaps the two spacer wings 22 is snapped onto each cross member 68. In the example shown in FIG. 15, the strip 71 is designed to produce a simple glazing and comprises, on the poor glass side, an extension 72 which extends to the plane of the outer face of the panels 6, 69 of a wall, extension on which will rest the joint cover 32.

 On the other side, the strip 71 has a retaining rib 73 for a lateral seal 74. The corresponding edge of the glass is in use sandwiched between the seal 74 and clips 24 masked by a joint cover 32.

This structure is found all around Bay 67.

As shown in FIG. 15, the lower edge of the pane 76 rests on the upper flange of the trough 21 via elastic cushions 77.

 As shown in FIG. 16, if it is desired to produce a double glazing, rods 71a are used that do not include the extension 72 but have on each side a retaining rib 73 for a lateral joint 74.

 During assembly, the rods 71 or 71a are placed on the two crosspieces 68 and the two sections 20, the joints 74 are stuck on the rods 71 and the cushions 77 are placed on the lower profile 68, then the glazings are put in place. 76 before locking them by the clips 24. Alternatively, the rods 71 and 71a can between delivered provided with seals 74.

 At the end of the worksite, the covers 32 are placed on all the profiles 20 and crosspieces 68.

 Thanks to the clearance i between each wing 9 and the adjacent panel 6, it is possible to engage the ends of the joint covers in the rails 7 and 8, as shown in Figure 1, eliminating the need to cut to precise length vertical joint covers.

 For the mounting of vertical joint covers, snap one end of the joint cover and then slide it into the adjacent rail 7 or 8. Then snap the other end, then sliding in the other direction, it is engaged in the other rail 8 or 7 respectively.

 In case of fire in the premises equipped with the partition according to the invention, even if the joint covers 32, made of aluminum or plastic, are destroyed, the clips 24 oppose the fall of the panels.

We benefit fully from this advantage if the uprights 20 are steel and not aluminum.

 According to an alternative embodiment shown in FIG. 17, the web 19 of the connecting section 20 is offset laterally with respect to the bottom 78 of each of the two gutters 21. In order for the profile to maintain its symmetry about a longitudinal axis, the two offsets are in opposite directions, and the web 19 has a stepped shape.

 This arrangement leaves free the central region of the bottom 78 of each channel 21 for the passage of a screw 79 for fixing an accessory 81 (shown schematically).

 As represented in FIGS. 1, 4 and 15, between the walls 4 of the insulating material such as rock wool 82 is placed. This installation is preferably carried out at the stage shown in FIG. 13, that is to say before setting up the second panel 6.

 Clips with two long wings such as 28 may be provided instead of a long wing and a short wing.

 In a simplified version, it is possible not to connect the uprights to the rails 7 or 8 by brackets, or to connect to one of the rails by a square.

 For mounting, it is also possible to engage and position in advance all the amounts in the rails, then to mount only at this stage all the panels.
