Description

DEVICE FOR MAINTAINING A FACING ELEMENT

DISTANCE OF A VAPOR BARRIER MEMBRANE AND CONSTRUCTIVE SYSTEM WITH DOUBLE FRAME COMPRISING SUCH DEVICE DOMAIN OF THE INVENTION

The present invention relates to a device for holding a facing element, such as a plasterboard, away from a vapor barrier membrane extending along an insulating material covering a surface, such as a wall or ceiling to be clad in said facing.

BACKGROUND OF THE INVENTION

Regulatory requirements in terms of thermal insulation dictate that buildings be rendered airtight.

To prevent the thermal insulation materials from deteriorating due to the condensation of water during changes in ambient temperature, it is known to have a vapor barrier membrane between the facing (which is generally in the form of plasterboard) of the wall and / or ceiling and the insulation material covering said wall and / or ceiling.

During the construction work of the building (electricity, plumbing, etc.), an operator may have to drill holes through the siding for example to pass cables, ducts, pipes, etc.

To preserve the effectiveness of the vapor barrier membrane, it is necessary to avoid as much as possible to pierce said membrane.

Therefore, to avoid damaging the vapor barrier membrane during these works, it is sought to maintain a sufficient distance between the facing and said membrane. A distance of a few centimeters thus allows an operator to pierce the siding and pass through the desired elements without affecting the vapor barrier membrane.

To minimize the time required for the installation of the facing elements, it is desirable to simplify as much as possible the introduction of the insulating material, the vapor barrier membrane and the fastening rails of the facing elements, while ensuring the distance above mentioned between the membrane and said rails.

The document EP 2 239 394 thus proposes a bracing system comprising a base having a tubular body and a bearing surface on the surface to be coated and a support member of the rail capable of sliding on the tubular body. Said system further comprises a screw adapted to be introduced into the tubular body for fixing the base to the surface to be coated, the screw thereby perforating the vapor barrier membrane which covers the surface to be coated. Said screw is provided with a head which seals the body tubular to prevent any air passage between the opening in the vapor barrier membrane and the outside.

However, this system has the disadvantage of being complex to set up. In addition, Chabanne Bâtiment proposes a device called "Waterproof Hanger". As illustrated in Figure 1, this device comprises a rod 2000 whose end 2001 is intended to be fixed on a beam 1000 of the building ceiling and the opposite end 2002, which is threaded, is pointed. This pointed rod is intended to perforate the insulating material 3000 which is thus maintained on a plurality of rods evenly distributed on the ceiling, then the vapor barrier membrane 4000. The passage of the rod through the insulating material is inconvenient on the one hand because of the generally large thickness to perforate and secondly because of the position of the operator, who has his arms raised. Moreover, the fact that the rod attached to the ceiling is pointed causes the risk of injury to the operator, especially to the head. This device further comprises a plate 5000 of square shape intended to be screwed onto the rod and serving as a support for the insulating material. Finally, the device comprises a jumper 6000, also intended to be screwed on the rod, for fixing a rail 7000 for fixing a plasterboard. The set up of the whole is therefore relatively long.

In order to avoid perforating the membrane, document EP 2 781 668 proposes a device for fixing a vapor barrier membrane on a frame integral with the surface to be coated, comprising a plate capable of engaging in said frame so as to trap the membrane between a surface of the armature and a surface of the plate. The surfaces intended to be in contact with the membrane are free of asperities liable to perforate the membrane. The plate comprises flexible arms adapted to be inserted into a corresponding housing of the frame. The plate is then held in place by means of a locking member which prevents the withdrawal of said arms. The device is designed so that the end of the locking member does not come into contact with the membrane. However, a major disadvantage of this device is that it causes deformation of the membrane in the region trapped between the plate and the armature. As a result, the membrane, which is in the form of a strip, has non-straight edges. Therefore, when an operator has to connect two adjacent strips by means of an adhesive tape, folds form under the adhesive tape, causing a significant risk of leakage. BRIEF DESCRIPTION OF THE INVENTION

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The device according to the invention is intended to be used in a double-frame construction system, comprising:

a first reinforcement intended to be secured to a surface, such as a wall or a ceiling, to be covered with a covering,

- A second frame for supporting facing elements, such as plasterboard for example.

In general, the first frame comprises a plurality of rails fixed parallel to each other on the ceiling or wall to be coated.

This first frame is intended firstly to maintain an insulating material along the ceiling or wall, and secondly to support the second frame.

The insulating material is generally in the form of rolls which are cut strips of a suitable length to place them between the rails of the first frame.

A vapor barrier membrane is arranged so as to cover the insulating material on its face opposite to the first armature. The vapor barrier membrane is generally in the form of rolls which are cut strips of a suitable length. When placed along the surface to be coated, successive flat strips are connected by an adhesive tape covering the edges of two adjacent strips.

In a manner known per se, the vapor barrier membrane is made of a waterproof material. The purpose of the vapor barrier membrane is to prevent moisture from entering and stagnating between the facing and the surface to be coated, which could cause the insulating material to mold.

The second frame generally comprises a plurality of rails, whose shape and dimensions may be different from those of the rails of the first frame. Facing elements, such as plasterboard, or suspended ceiling plates or acoustic ceiling, are attached to the rails of the second frame.

As will be seen in detail below, the second frame is fixed to the first frame by means of a plurality of holding devices that maintain a distance between the vapor barrier membrane and the facing elements. Given the provision of the vapor barrier membrane between the two frames, the establishment of said holding devices involves a perforation of the vapor barrier membrane. The retaining devices are, however, designed so as to restore the tightness of the vapor barrier membrane by exerting a pressure on said membrane around the perforation while keeping the membrane substantially flat, as seen in FIGS. 10C and 11 . Thus, the perforation of the vapor barrier membrane during assembly of the constructive system is not detrimental to the sealing function of said membrane, and the edges of the membrane remain straight, so that the formation of folds is avoided when the membrane is connected to an adjacent membrane by an adhesive tape.

Figure 2 is an exploded view of a device according to one embodiment of the invention.

The device comprises:

a plate 1 capable of engaging in the first armature, which has been previously secured to the surface to be coated, in particular by means of suspension (not shown),

a member 2 for fixing a support of the facing element, comprising a first portion intended to engage in the support of the facing element and a second portion intended to engage in the plate, said portions being spaced from each other in a direction perpendicular to the surface to be coated.

When laying the facing, the vapor barrier membrane 300 is interposed between the plate 1 and the fixing member 2.

As best seen in Figure 3, the second portion 20 includes a tip for perforating the vapor barrier membrane upon engagement of said second portion in the platen.

Furthermore, the engagement of the member 2 in the plate 1 comprises the exercise of a compressive force on the vapor barrier membrane in the region surrounding the hole caused by the tip, in order to minimize the leakage loss due to perforation. This compression force is exerted by a closed bearing area, which extends in the same plane as the membrane to not deform it. Advantageously, this support zone is in the form of a line.

In the embodiment illustrated in Figure 2, the first frame is in the form of a rail whose section has a general shape of W. As it is 7A, said rail 100 comprises two legs 104 connected at one of their ends by a bottom which is not flat but has a protrusion directed towards the other end of the legs 104, defining a groove 102 surrounded by two surfaces 103 substantially flat. Advantageously, the legs 104 have, at their end opposite the bottom, a flange 105 directed towards the inside of the rails, and which allows the platten to snap onto the rail 100 as well as the attachment of said rail to suspension lines ( not shown) for fixing the first armature on the surface to be coated.

Figure 3 is an exploded view of another embodiment, wherein the first frame is in the form of a rail commonly used in construction. Said rail has a generally U-shaped section, the two legs 104 are connected at one of their ends by a bottom 101 (Figure 9A). Advantageously, at their opposite end to said bottom 101, the legs 104 have a respective flange 105 extending inwardly and allowing the latching of the plate 1 on the rail 100 as well as the fixing of said rail on lines ( not shown) for fixing the first armature on the surface to be coated.

In the embodiments of Figures 2 and 3, the portion 21 of the member 2 is shaped to allow its engagement, for example by snapping or sliding on a rail 200 forming the second frame.

Figure 4 is an exploded view of another embodiment, adapted to the establishment of a suspended ceiling or acoustic ceiling. In this case, the portion 21 of the member 2 is shaped hook or loop 28.

Although the first armature is shown in FIG. 4 in the form of a rail with a U-shaped section as in FIG. 3, a rail with a W section could be used for the first armature as in FIG. as far beyond the scope of the present invention.

According to a preferred embodiment of the invention, the holding device further comprises two arms 3 which are articulated on either side of the plate 1.

In the embodiments illustrated in Figures 7A-7D and 9A-9D, each arm is shown as a composite member comprises a metal section 30 having a substantially planar bearing surface for the insulating material and a member 32 platinum bonding member of a thermoplastic material overmolded on a portion of said profile 30.

However, this embodiment is not limiting and the skilled person may choose to make the arms entirely of metal or entirely of plastic material.

The length of the arms is typically between 10 cm and 70 cm.

In a particular embodiment associated with long arms (that is to say more than 60 cm), the arms have one end adapted to cooperate with the end of another arm. As illustrated in FIG. 12, this makes it possible to connect an arm of a device holding with one arm an adjacent holding device. This embodiment is particularly advantageous when the rails of the first frame are more spaced than the standard distance used in construction (which is 60 cm). The arms integral with each other and allow to support the insulating material. This makes it possible to space the rails of the first armature by a distance equal to the width of the insulating material (which is typically delivered in the form of rolls 120 cm wide) while ensuring a durable retention in time of said material.

When the spacing between the rails of the first frame is substantially equal to the width of the insulating material, it can be maintained between the rails by wedging. In this case, it is possible to omit the arms 3. According to a variant (not shown), it is also possible to provide at the end of each arm of the holding device a securing means to a rail of the first armature adjacent to the rail on which is mounted the plate of said device.

We will now describe in more detail the structure of the plate 1 and the member 2. With reference to FIGS. 5A and 5B, the plate 1 has a generally U-shaped shape, the bottom 12 of which comprises a passage orifice 13 engagement of the tip of the second portion of the fastener. On either side of the bottom 12 extend two substantially symmetrical legs 10 which, at their end opposite the bottom 12, have a respective flange 11 directed inwards. Each flange January 1 forms a latching means of the plate 1 on a respective flange 105 of the rail 100 forming the first armature.

Particularly advantageously, each rim January 1 does not have a solid shape but a perforated form comprising a plurality of parallel recesses regularly spaced in the manner of a comb, the width of the recesses being greater than the thickness of the lines commonly used in construction. This particular conformation of the flanges 1 1 allows a greater latitude of positioning of the plate on the rail 100, regardless of the location of the lines. Indeed, each line being in the form of a flat part a few millimeters thick and being positioned in a plane perpendicular to the longitudinal axis of the rail 100, the plate can be placed on the rail by positioning a recess of each flange 1 1 around the hanger.

The bottom 12 has an outer surface (opposite the legs 10) which is intended to serve as a support surface for the vapor barrier membrane.

On the inner side of the plate (that is to say directed towards the legs 10), the orifice 13 is surrounded by an inclined portion of thread 14 intended to cooperate with the member 2 to create a quarter-type fastener of turn. This attachment has two functions: on the one hand, to fasten the member 2 to the plate 1 and on the other hand to exert a compression on the membrane vapor which is taken between the outer surface of the bottom 12 and the surface of the flange 23 of the member 2, according to a closed bearing zone which extends in the plane of the membrane.

Referring to Figure 6, the second portion 20 of the fastener 2, which is intended to engage in the plate 1, comprises a tip 22 adapted to perforate the vapor barrier membrane and a flange 23 whose surface outside (ie pointed towards the tip) is intended to receive the membrane vapor barrier.

The tip 22 is provided with an inclined thread portion designed to cooperate with the thread portion 14 arranged around the orifice 13 of the plate 1.

Advantageously, the outer surface of the bottom 12 of the plate 1 is flat at least in the region surrounding the orifice 13. Similarly, the outer surface of the flange 23 is flat. Thus, the vapor barrier membrane is not deformed during its introduction and the seal, which is provided between two flat surfaces, is controlled more easily.

The fixing member 2 further comprises a portion 21 designed to engage in the support of the facing element. The portions 20 and 21 are connected by a rod 24 whose length is defined according to the distance to be maintained between the vapor barrier membrane and the facing element.

The plate 1 and the member 2 are advantageously made by injection of a thermoplastic material. However, with an adaptation of the design, the plate can also be made by folding and / or stamping a metal sheet.

The member 2 is substantially identical in the embodiments of Figures 2 and 3. In contrast, the shape of the plate 1 is different according to the rail 100 forming the first frame has a W-shaped section as in Figures 2 and 1 1 or a U-shaped section as in Figures 3 and 10D. Indeed, in the embodiment of Figures 2 and 1 1, the groove 102 defines a housing for the tip of the member 2; the length of the legs 10 of the plate is then substantially equal to the height of the rail 100. In the embodiment of Figures 3 and 10D, the bottom 101 of the rail being plane, it is the plate 1 which must be arranged to understand a housing for the tip of the member 2. In this case, the legs 10 of the plate are longer than in the previous case. In particular, as can be seen better in FIG. 5A, the legs 10 are not rectilinear but have an intermediate shoulder whose upper part forms a bearing surface for the rail 100 (see FIGS. 10A-10B), while the part of the legs located between this shoulder and the bottom 12 defines a housing 19 (see Figures 10C-10D) for the tip of the member 2, said housing being located under the rail 100.

FIGS. 7A to 7D illustrate various stages of the positioning of the plate on the first frame and the deployment of the arms, according to an embodiment in which when the plate 1 is in the position of engagement in said frame 100, the pivot axis of the arms is parallel to the surface to be coated. Referring to Figure 7A, the rail 100 forming the first armature is pre-attached to the surface to be coated (not shown here) and extends parallel to said surface. The section of the rail 100 can be indifferently W (as in Figures 7A-7D) or U.

The plate 1 is provided with the arms 3 in a position perpendicular to the surface to be coated.

Although not shown, the insulating material is disposed along the rail 100.

Referring to Figure 7B, the plate is secured to the rail 100 by snapping flanges 1 1 on the flanges 105 of the rail.

Then, with reference to FIG. 7C, each arm is pivoted towards the surface to be coated (in the direction of the arrow for the arm 3 located on the left of the figure), so as to bring said arm into a position substantially parallel to the surface to be coated and perpendicular to the rail 100. In this position, each arm 3 forms a bearing surface for the insulating material and thus promotes its resistance over time.

Figure 7D illustrates the configuration of the plate and arms after complete deployment thereof.

Particularly advantageously, the plate and the arms have complementary means for locking each arm in the deployed position.

FIGS. 8A and 8B are detailed views of the plate and an arm of FIGS. 7A-7D, respectively in the initial position of the arm before deployment (as in FIG. 7B) and in the final locked position (as in FIG. 7D). The plate 1 comprises a partition perpendicular to the axis of pivoting of the arm which has a passage 15 for the axis of the arm, and an opening 16. Furthermore, the arm comprises a cylindrical pin forming the pivot axis 33 of the arm, and a lug 31. The arm is articulated vis-à-vis the plate by the axis 33. If the arm portion 3 articulated to the plate 1 is made of thermoplastic material, the pin 33 and the lug 31 can be made molding.

With reference to FIG. 8A, in the initial position as illustrated in FIG. 7B, the opening 16 is free.

When pivoting the arm towards its deployed position, the lug 31 engages in the opening 16 until it clicks into place (see FIG. 8B), thus preventing a return movement of the arm towards the initial position.

Naturally, those skilled in the art may define another design of the blocking means without departing from the scope of the present invention.

FIGS. 9A to 9D illustrate various stages of the positioning of the plate on the first armature and the deployment of the arms, according to an embodiment in which when the plate 1 is in the position of engagement in said armature 100, the Pivot axis of the arms is perpendicular to the surface to be coated. Referring to Figure 9A, the rail 100 forming the first armature is pre-attached to the surface to be coated (not shown here) and extends parallel to said surface. The section of the rail 100 can be indifferently U (as in Figures 9A-9D) or W.

The plate 1 is provided with the arms 3 in a position parallel to the surface to be coated and parallel to the rail 100.

Although not shown, the insulating material is disposed along the rail 100.

Referring to Figure 9B, the plate is secured to the rail 100 by snapping flanges January 1 on the flanges 105 of the rail.

Then, with reference to FIG. 9C, each arm is pivoted in a plane parallel to the surface to be coated (in the direction of the arrow for the arm 3 located on the right of the figure), so as to bring said arm into a position substantially perpendicular to the rail 100. In this position, each arm 3 forms a bearing surface for the insulating material and thus promotes its holding in time.

Figure 9D illustrates the configuration of the plate and arms after complete deployment thereof.

Although not shown in Figs. 9A-9D, a means for locking each arm in its deployed position may be provided. This means can be of the same type as that illustrated in FIGS. 8A-8B, or different.

Figures 10A to 10D illustrate different stages of the establishment of the fastener and the second frame on the plate secured to the first frame.

Figure 10A illustrates the plate 1 placed on the rail 100 forming the first frame. When arms 3 are hinged to the plate, they are in their deployed position, as in Figures 7D and 9D described above.

In this situation, the insulating material (not shown) is arranged along the rail 100, above the arms 3.

The vapor barrier membrane 300 is put in place along the outer surface of the bottom 12 of the plate 1. Due to its geometry, the plate 1 maintains a distance between the insulating material and the vapor barrier membrane 300.

With reference to FIG. 10B, the member 2 is provided opposite platen 1.

With reference to FIG. 10C, the tip 22 of the member 2 is introduced into the orifice 13 of the plate 1, which has the effect of perforating said membrane by means of the tip 22. To engage the member 2 in the plate 1, it exerts a helical movement on the member 2 due to the cooperation between the thread portion 14 and the thread portion of the tip 22. Thus, the vapor barrier membrane is gradually compressed between the outer surface of the bottom 12 of the plate 1 and the surface of the collar 23 of the member 2. This compression of the vapor barrier membrane makes it possible to seal said membrane despite the perforation, without deforming the membrane, the support zone surrounding the perforation being coplanar with the membrane.

With reference to FIG. 10D, the rail 200 forming the second armature is placed on the portion 21 of the member 2. The rail 200 advantageously extends in a plane parallel to the surface to be coated, but in a perpendicular direction at the first frame. The rail 200 is kept at a distance from the vapor barrier membrane 300 by the rod 24 of the body 2.

It should be noted that, during the implementation of the invention, the insulation is not perforated.

On the other hand, the implementation of the device does not require any tools.

The installation of the device according to the invention is therefore much simpler and faster than in the case of the device illustrated in FIG.

Finally, the fact that the tip for perforating the membrane is located on the member 2 which is handled by the operator and not on a part attached to the wall to be coated minimizes the risk of injury.
