Description

accessory for a frame system for lining a structure

[0001] The present invention relates to the field of framework systems for lining a vertical or horizontal, interior or exterior wall. Prior art

[0002] Currently, building facades can be insulated from the outside in order to preserve the interior space of said buildings.

[0003] One solution is to create an external thermal insulation solution. This type of cladding involves installing panels made of insulating materials such as mineral wool or polystyrene on the facade using mortar, glue, adhesive mortar, or dowels fixed to the facade. The entire structure is then covered with plaster.

[0004] A second solution is to create cladding, i.e. to mount a frame on the wall onto which facing panels are fixed. This frame is such that it allows the installation of panels made of insulating materials such as mineral wool (glass or rock). These panels are fixed to the facade by rosettes.

[0005] In particular, there is a construction which is a cladding whose frame comprises U or C-shaped profiles, that is to say comprising a central core and through which two parallel wings extend, perpendicular to said central core. These profiles are fixed to the facade by means of fixing plates. More particularly, the profiles are arranged so that one of the parallel wings is in contact with the facade.

[0006] Profiles can be used because the two parallel wings of the C form a space into which insulating material can be inserted. On these profiles, a facing is arranged by means of a horizontal or vertical counter-frame.

[0007] The disadvantage of this construction is that it is necessary to install an air gap to allow ventilation of the building. This air gap then requires additional construction. It also does not allow the cladding to be placed at a variable distance from the wall, without changing the thickness of the profiles. Profile thickness is understood to mean the width of the profile core. The invention solves the problem by allowing, for a given profile thickness, the cladding to be placed at different distances from the wall, thus allowing the use of a variable thickness of the insulating material, depending on the thermal needs of the structure to be insulated.

[0008] Furthermore, the disadvantage of current systems is that the insulating material panels are fixed to a wall using dowels or hanging accessories that require the wall to be reinforced. This is a long and tedious process.

[0009] Thus, the invention seeks to solve the problems of the prior art by providing an accessory making it possible to hold an insulating panel in a frame simply and without drilling the wall.

[0010] To this end, the invention relates to an accessory for holding an insulating panel in a housing formed by structural elements comprising a main plate comprising attachment means allowing the attachment of said holding accessory to a structural element, said holding accessory further comprises holding elements.

[0011] The advantage of the invention is that it allows an insulating panel to be held in a frame simply and without drilling the wall, since said holding accessory is fixed to the structural element of the frame forming the frame.

[0012] This avoids drilling holes and installing dowels.

[0013] According to one example, the holding elements comprise at least one arm extending from the plate, said arm comprising a first portion extending from the plate and a second portion, extending from the first portion in a direction parallel to the surface of the insulating panel.

[0014] According to one example, the accessory comprises two arms, preferably having the same shape and dimensions.

[0015] According to one example, the holding elements further comprise anchoring means comprising at least one relief.

[0016] According to one example, said at least one relief is arranged on the second portion of at least one arm.

[0017] According to one example, the attachment means comprise at least one hook, said hook being capable of cooperating with a free end of the structural element.

[0018] According to one example, said hook is arranged on the main plate or on an arm.

[0019] According to one example, the attachment means further comprise a protrusion capable of being inserted into a hole in the structural element, said protrusion acting as a stop.

[0020] The invention further relates to a framework for lining a structure, said framework comprising a frame carrying a facing, said framework comprising a plurality of frame elements arranged to form at least one space in which an insulating material in the form of at least one panel of insulating material is capable of being placed, said framework being fixed to the structure by fixing means characterized in that the thickness of the frame fixed to the wall is greater than that of the at least one panel of insulating material in order to create an empty space between the insulating material and the facing and in that said framework comprises at least one holding accessory according to the invention, said accessory being fixed to a frame element.

[0021] According to an example, which thickness of the reinforcement fixed to the structure is the thickness of the reinforcement elements.

[0022] In one example, the thickness of the reinforcement attached to the structure is the thickness of the reinforcement elements and the fastening elements.

[0023] According to one example, the reinforcement elements are profiles comprising a central core and at least a first wing extending orthogonally to said central core, said first wing allowing the facing to be fixed.

[0024] According to one example, said first wing comprises a return extending parallel to the central core.

[0025] In one example, the return of the first wing has a length equal to the empty space between the insulating material and the facing.

[0037] In the, a facade 1 is shown. This facade 1 comprises a lining frame 10 arranged to be fixed to a structure 2 such as a building in order to form a facade. The supporting structure 2 is made of wood or masonry. The structure 2 is a floor or ceiling slab or a wall. The wall can be vertical or horizontal or inclined.

[0038] The frame 10, visible in figures 2 and 3, comprises a plurality of reinforcement elements 12 arranged together to form a frame 11. This frame 10 is arranged to comprise, to allow the installation of an insulation layer 14. This insulation layer 14 comprises a plurality of insulating panels 140. These insulating panels 140 are made of an insulating material of the glass wool or rock wool or polystyrene or wood wool type or any other possible insulating material. These panels have a thickness E1 of between 70 and 300 mm.

[0039] The frame 10 also comprises a facing 16. This facing 16 comprises, in the case of an exterior lining, a cladding which can be made of wood or PVC or stone or any other exterior cladding such as at least one plate covered with a coating.

[0040] The reinforcement elements 12 are profiles as visible in the.

[0041] In one embodiment, the profiles 12 have a section that can have several shapes. The profiles 12 comprise a central core 121 and at least one wing 122 called the first wing. This wing 122 extends from the central core. Preferably, the wing 122 extends orthogonally to the central core so as to form at least one L. The frame elements 12 are made of metal or metal alloy or plastic or composite materials.

[0042] The reinforcement elements 12 are arranged to form a reinforcement 11. This reinforcement 11 comprises reinforcement elements 12 extending vertically, along a y axis, that is to say orthogonally to the ground and reinforcement elements extending parallel to the ground, that is to say along an x ​​axis. The reinforcement elements 12 are arranged to extend from the structure 2 along a z axis thus defining a depth. The reinforcement elements 12 are arranged to, when installed, have at least one bearing face. It is understood that the wing 122 extends parallel to the plane of the supporting structure.

[0043] More particularly, the frame 11 then comprises a plurality of lines comprising at least one frame element 12, the lines are parallel to each other. These lines are vertical or horizontal and extend over the entire height or width of the structure to be lined. The lines are, for example, arranged to have a spacing between two lines of at least 0.6m, preferably between 0.6 and 4m.

[0044] The frame elements 12 are then arranged to form spaces into which the insulating material panels 14 are able to be inserted.

[0045] Reinforcing elements 12 arranged between the lines, parallel to the ground, are used for the window headers. The reinforcement elements 12 arranged parallel to the ground are fixed to the reinforcement elements 12 extending vertically. Optionally, connecting pieces are used to fix the reinforcement elements 12 arranged parallel to the ground to the reinforcement elements 12 extending vertically. It is also possible to use a first set of reinforcement elements that are only horizontal (along the x axis), or only vertical (along the y axis), in combination or not with a second set of reinforcement elements 12 in a perpendicular direction.

[0046] The frame 11 further comprises fixing means 13 allowing the fixing of the frame elements 12 to the structure 2 as visible in the.

[0047] In a first form, the fixing means 13 comprise at least one fixing element 130. This fixing element 130 is in the form of a bracket or a profile having an L or T shape. Each fixing element 130 thus comprises two portions, a first portion 130a serving for its fixing on the frame 11 and a second portion 130b for its fixing to the structure 2. The second portion 130b preferably extends orthogonally to the first portion 130a. The fixing to the structure 2 and / or to the frame 11 is done by bolting or screwing. Two frame elements 12 can be fixed to the same fixing element 130.

[0048] The reinforcement elements 12 are fixed to the fixing elements 130 by their central core 121. It is then understood that the plane of a central core 121 of a reinforcement element 12 extends orthogonally to the plane of the facade. Said at least one wing 122 of the reinforcement elements 12 is used for the installation of the facing 16. The central core 121 has a length of between 70 and 400 mm.

[0049] The attachment of the reinforcement element 12 to the fixing element 130 by its central core 121 makes it possible to have a mechanical resistance greater than a situation in which the central core was directly attached to the structure 2. This better mechanical resistance makes it possible to reinforce the mechanical moment of inertia. Therefore, as the mechanical moment of inertia is increased, the distance between two fixing elements 130 can be increased up to 2 or 3 meters. In this case, the number of fixing elements 130 decreases.

[0050] The central cores 121 of two reinforcement elements 12 of two adjacent lines are then parallel and form a space 30 between which one or more panels 140 of insulating material are inserted.

[0051] The frame 10, that is to say the assembly of the reinforcement elements 12 and the fixing elements 130, is arranged to have a thickness greater than that of the panels 140 of insulating material. This thickness is the distance between the facade and the wing of the reinforcement elements 12 which carries the facing 16.

[0052] However, the panels 140 of insulating material, inserted between two lines of reinforcement elements 12, are in direct contact with the structure 2. Thus, once the facing 16 is installed, there is then a space 30 between the panel 140 of insulating material and said facing 16 as visible in the. This space 30 then has a thickness, preferably of at least 20 mm. Even more preferably, this space has a thickness of between 40 and 90 mm.

[0053] This space 30 between the panel 140 of insulating material and the facing 16 then takes the form of an empty space 30. This empty space is likened to an air gap which allows the building to be ventilated. The presence of this air gap makes it possible to avoid having to install an additional structure or reinforcement to provide such ventilation. This difference in thickness between the panel 140 of insulating material and said facing 16 is obtained in different ways.

[0054] A first way consists of providing reinforcement elements 12 whose thickness is greater than that of the insulating panels 140. This thickness of the reinforcement elements 12 is equal to the length of the central core 121 of the profile forming the reinforcement element 12.

[0055] A second way to obtain a difference in thickness between the panel 140 of insulating material and said facing 16 consists in having the thickness of the reinforcement elements 12, that is to say the length of the central core 121 of the profile forming the reinforcement element 12, which is identical to that of the insulating panel 140 but to have this reinforcement element 12 arranged at a distance from the structure. It is then understood that the fixing elements 130 are arranged to move the reinforcement 10 away from the structure, the reinforcement elements 12 being offset from the facade.

[0056] A third way to obtain a difference in thickness between the panel 140 of insulating material and said facing 16 consists in combining the thickness of the reinforcement elements 12, that is to say the length of the central core 121 of the profile forming the structural element, and that of the fixing elements 130 arranged to move the reinforcement 10 away from the structure 2, to obtain the air gap. In this case, it is possible to have a first portion 130a of the fixing element 130 with a great length and a reinforcement element 12 with a central core 121 of short length or the reverse, that is to say a first portion 130a of the fixing element 130 with a short length and a reinforcement element 12 with a central core 121 of long length. Having a reinforcement element 12 with a reduced central core 121 makes it possible to limit the influence of thermal bridges compared to a solution in which the reinforcement element 12 would have a longer central core.

[0057] The advantage of distancing the reinforcement 11 from the structure 2 is that it allows for reducing contact between the reinforcement elements 12 and the structure. Indeed, when the reinforcement elements 12 are not placed at a distance from the facade, said reinforcement elements 12 are in contact with the structure 2, the contact being made over the entire length of said reinforcement elements 12, it promotes the appearance of thermal bridges. Placing the reinforcement elements 12 at a distance allows for reducing this risk.

[0058] Cleverly according to the invention, the lining frame comprises holding means 20. These holding means 20 are arranged to retain the insulating panels 140.

[0059] The holding means 20 comprise at least one holding accessory 200 as visible in the figure. This holding accessory 200 is made of metal or metal alloy or plastic or any other material suitable for use.

[0060] The holding accessory 200 comprises, according to a first embodiment, a so-called main plate 202 and attachment means 204. The attachment means 204 allow the holding accessory to be fixed to a structural element.

[0061] According to the invention visible in the, the holding accessory 200 further comprises holding elements 206 for the insulating panel 140. These holding elements 206 comprise at least one arm 207. This arm 207 extends from the main plate. This arm 207 comprises two portions, a first portion 2070 which extends from the main plate to grip the reinforcement element 12 and a second portion 2071 which extends from the first portion. The first portion extends orthogonally or inclined relative to the plane of the main plate. The first portion is rectilinear, curved or comprising several sections inclined relative to each other.

[0062] The second portion 2071 extends substantially parallel, preferably parallel to the plane of the main plate.

[0063] This second portion 2071 advantageously allows the insulating panel to be supported to hold it in place. Fixing said holding accessory to a structural element avoids making holes in the wall to fix the panel.

[0064] The first portion 2070 makes it possible to distance the second portion from the base plate in order to take into account the spacing between the insulating panel and the facing 16.

[0065] The second portion 2071 forms a flat surface which, preferably, comes to bear on the insulating panel 140. It is then understood that the first portion 2070 makes it possible to put the second portion 2071 in contact with the insulating panel.

[0066] In a variant visible in the, the second portion of the arm comprises anchoring means 208. These anchoring means comprise at least one relief 2080 arranged on said arm. This relief preferably has a shape allowing it to be inserted, to perforate the panel of insulating material when the holding accessory is put in place. The relief has a maximum length of 100 mm. The relief is, for example, a point, a blade or has a shape suitable for perforating the insulating panel.

[0067] The presence of relief(s) 2080 on the second portion of the arm 2071 makes it possible to hold the insulating panel. It is then understood that the reliefs perforating said panel prevent said panel from moving laterally or vertically.

[0068] It is also possible for the relief(s) to be considered as an extension of the second portion 2071. It is then understood that the relief(s) have the function of being in contact with said panel to hold it in its housing. In the case where the relief is not perforating, the contacting of the relief(s) 2080 with the panel is operated by the length of the first portion and the length of the reliefs as visible in the. In another variant, the holding accessory comprises a second arm 207. This second arm 207 extends from the main plate. This second arm 207 also comprises a first portion and a second portion and furthermore anchoring means. This second arm makes it possible, with the first arm, to have a holding accessory which has a U shape. Preferably, this second wing is identical to the first wing, that is to say that it has an identical length.

[0069] Preferably, the two arms 207 are arranged to have symmetry with respect to an axis passing through the middle of the main plate.

[0070] The second portion 2071 of each arm extends to have a length of at least 120mm.

[0071] The holding accessory further comprises attachment means 204 as visible in the. These attachment means 204 comprise at least one hook 2041 capable of cooperating with a free end of the structural element 12. It is understood that the hook cooperates with a wing of the structural element 12 as visible in FIGS. 11 and 12a and 12b. This hook extends from the main plate or from one of the arms 207.

[0072] In the case of two hooks 2041 as visible in the, the hold is ensured because two free ends are present.

[0073] In the case of a single free end, the accessory includes a single hook. The attachment of the holding accessory to the structural element is then made but can be improved.

[0074] This improvement in grip can be achieved in different ways.

[0075] A first way consists of providing a configuration of the holding accessory in which the hook is located, at the level of the main plate, opposite at least one arm. It is understood that for a holding accessory with a single arm 207, the hook 2041 is arranged opposite. This configuration allows, once the holding accessory is fixed to the structural element, said arm to have a stop function preventing said accessory from becoming detached from the structural element 12.

[0076] A second way is that the attachment means 204 further comprise a stud or protrusion 2042 as visible in the. This protrusion extends from the main plate or from an arm and is arranged to be inserted into a hole or recess in the structural element 12. This protrusion and the associated hole or recess provide an improvement in the attachment of the holding accessory. The protrusion optionally has an extra thickness. This extra thickness allows, when the protrusion cooperates with a through hole, to have a snap-fastening which locks the protrusion to the structural element 12.

[0077] The first way and the second way are combinable and are not limiting. It is possible to have, for an accessory with an arm, the hook arranged on the same side as said arm.

[0078] In another embodiment visible in the, the holding accessory 2004 comprises a main plate 202'. This main plate 202' is flat and used as holding elements 206.

[0079] The main plate 202' further comprises arms 2044 extending orthogonally to the plane of the main plate 202'. These arms 2044 serve to grip the frame element 12 and form part of the attachment means 204.

[0080] The main plate 202' further comprises anchoring means 208 such as teeth 2080' capable of being inserted into the insulating material.

[0081] In one variant, the main plate 202' is made of a material capable of deforming. This ability makes it possible to deform the main plate 202' to bring the anchoring means 208 into contact with the insulating material and ensure the presence of the air gap, if such a gap must be present.

[0082] These anchoring means 208 can be replaced by retaining means capable of keeping the insulating material at a distance from the main plate 202'.

[0083] In a variant, the profile forming the reinforcement elements 12 is arranged to be inserted into the panel 140 made of insulating material. For this, the reinforcement element 12 comprises a second wing 122 extending orthogonally to the central core 121 as visible in FIGS. 15 to 18. This second wing extends parallel to the first wing. This second wing extends in the same direction as the first wing to form a U-shaped profile or in an opposite direction to form a Z-shaped profile. The second wing 122 has a length that is identical or different, greater or less, than that of the first wing.

[0084] This second wing 122 is arranged to cooperate with the panel of insulating material. This cooperation takes the form of an insertion of said second wing 122 into the panel of insulating material. For this, said panel optionally comprises an incision. In the event that it is made, this incision is arranged on the edge of the panel 140 of insulating material. This incision is then made prior to the installation of the panel or during its installation. This incision allows the second wing 122 to be inserted therein. This insertion allows better support of the panel since it is engaged with a reinforcement element 12. This insertion also allows the reinforcement element 12 to serve as a guide rail. It is then possible to move the panel 140 of insulating material along the reinforcement element 12, in particular to put it in place.

[0085] In another variant, the first wing 122 comprises a return 123 as visible in the. This return extends parallel to the central core. This return extends in the direction towards the facade. This return 123 is used as a stop in the event that the insulating material panel(s) become detached from the facade.

[0086] Preferably, the return of the first wing 122 has a length equal to the thickness of the desired air gap. This allows the return 123 to hold the insulation in place to ensure that the air gap maintains a constant thickness.

[0087] In another variant, the fixing means 13 comprise bolts or screws for directly fixing the reinforcement elements 12 to the structure 2.

[0088] Of course, the present invention is not limited to the illustrated example but is susceptible to various variants and modifications which will appear to those skilled in the art.

[0089] Indeed, it is possible to use the lining frame 1 according to the invention for interior lining. In this case, the frame 10 is fixed to the interior wall and the facing is, for example, in the form of a plasterboard which can be covered with a coating and / or paint.
