Definitions
- the present invention belongs to the field of prefabricated panels.
- Each panel consists of a frame closed by two plates: a front plate and a rear plate made of a material such as plaster or wood.
- This frame and these plates form a housing in which an insulating material is placed.
- This insulating material may be mineral wool in the form of flakes.
- the frame is fixed to the back plate, said back plate then being placed flat / horizontally so that the insulating material can be placed in the space delimited by said back plate and the frame.
- This horizontal position of the rear plate makes it possible to place the insulating material while ensuring a good distribution of it and therefore a homogeneity of thermal performance.
- the front plate is then fixed to the frame in order to close the panel.
- the insulating material is more sensitive to shocks occurring during its transport. These shocks tend to cause said material to settle in the housing. Such compaction is characterized by the appearance of empty zones (or thermal bridges) because the flakes of mineral wool stick together. Thus, the result is that the flakes are no longer evenly distributed, causing a drop in the thermal performance of the panels. Summary of the invention
- the present invention seeks to solve the problems of the prior art by providing a prefabricated panel for a wall whose thermal performance has less deterioration following shocks, in particular following transport.
- the invention relates to an insulating panel comprising a bottom and a cover connected together at their periphery by a side wall forming a housing in which an insulating material is placed, characterized in that said insulating panel further comprises means for retention allowing the maintenance of the insulating material in said panel and preventing it from collapsing.
- the retention means comprise spikes extending from the bottom of the insulating panel.
- the pins extend from a structure fixed to the bottom of the insulating panel.
- the structure comprises a flexible sheet, from which the pins extend, arranged in the housing of the insulating panel.
- the structure comprises two parallel flexible sheets, from which the pins extend, arranged in the housing of the insulating panel.
- the pins are integral with the structures at the level of the intersections of the threads.
- the barbs extend orthogonally to the bottom and to the lid.
- the spikes have a length equal to at least 25% of the distance between the bottom and the lid, preferably at least 50% of the distance between the bottom and the lid and even more preferably at least 75%.
- the spikes are spaced apart by a distance of 2 to 20cm, preferably 2 to 15cm, and preferably 5 to 10cm.
- the distance between the pins is constant.
- the pins are positioned to be aligned in the form of a grid.
- the pins are positioned to be staggered.
- the spikes are made of a metallic or plastic material.
- the insulating material is in the form of flakes. According to one example, the insulating material has a density of between 10 to 75 kg/m3, preferably from 15 to 45 kg/m3.
- the invention further relates to a wall composed of a plurality of insulating panels according to one of the preceding claims, said insulating panels being fastened to each other.
- the invention also relates to a method for assembling an insulating panel according to the invention, characterized in that it comprises the following steps:
- FIG. 1 schematically shows a prefabricated panel according to the invention
- FIG. 3 schematically shows an open panel provided with retention means according to the invention
- FIG. 4 schematically shows a side view of an open panel provided with retention means according to the invention
- FIG. 5 schematically shows a side view of a variant of an open panel provided with retention means according to the invention
- FIG. 8 and 9 schematically represent a variant of the retention means using a structure
- FIG. 10a, 10b, 11 and 12 schematically represent a variant of the retention means using a double structure.
- - Figure 13 shows a diagram of settlement in percentage according to the invention and according to the prior art.
- a panel 10 according to the invention is shown.
- a panel comprises a frame 12 or side wall, preferably rectangular or square, closed by two plates called front plate 14 called cover and rear plate 16 called bottom.
- the frame 12 and the two plates 14, 16 are arranged so that the two plates are preferably parallel to each other.
- the frame is, for example, made of wooden cleats and the plates are made from a material based on plaster or wood.
- This panel has dimensions such that the panel has a height of between 1 and 6 m, a width of between 1 and 6 m and a depth of between 10 and 60 cm.
- the frame 12 and the two plates 14, 16 form a housing 17 or space in which an insulating material 20 is placed as shown in Figure 2.
- This insulating material or insulator 20 is a material of the mineral wool type such as glass wool or rock wool or an insulating material such as wood wool.
- the latter is in the form of flakes or nodules having a density of 10 to 75 kg/m3, preferably of 15 to 45 kg/m3.
- the frame 12 and the rear plate 16 are fixed then the whole is laid flat resting on the rear plate. This positioning allows access to the space formed by said rear plate 16 and frame 12.
- This space 17 can be filled with the insulating material before it is closed by the front plate.
- the panel 10 comprises retention means 30 as shown in Figure 3.
- These retention means 30 are means for holding the flakes in place during transport of the panel, that is to say when it is manipulated, undergoes shocks and is positioned in different ways on one or the other of its faces.
- These retention means 30 comprise a plurality of pins 32, that is to say at least two pins. These pins 32 are in the form of rods. We then understands that these pins 32 are elements whose cross section has a negligible diameter compared to their lengths. These pins or rods 32 are arranged in the panel so as to extend in a direction substantially orthogonal to the plane of the front 14 or rear 16 plates as seen in Figures 3 and 4. This means that the pins 32 or rods are extend orthogonal to the plane of the plates or are inclined by a maximum of 45 degrees with respect to an axis orthogonal to the plane of the plates.
- this plurality of studs 32 is to increase the friction that may exist between the flakes among themselves and between the flakes and the structure of the panel. This increase in friction tends to provide better resistance to the flakes during shocks, in particular during transport.
- the invention proposes to have a plurality of pins 32 distributed in the panel.
- the pins 32 are made of a material of the metal or plastic or wood type.
- the material used has thermal properties so that the presence of the spikes does not disturb the performance of the panel.
- the number of pins 32 is such that the spacing between two pins is between 2 to 20cm, preferably from 2 to 15cm, and preferably from 5 to 10cm.
- This spacing varies according to the density of the insulating material. Indeed, as can be seen below with a panel having a height of 550mm, a width of 550mm and a thickness of 165mm, several spacing configurations (5 and 8.5cm) and density (20, 30 and 40 kg/m3) were tested. The table below illustrates the settlement (in mm) for different densities of insulating materials and for different spacings between pins.
- This spacing between the pins 32 is preferably constant but it is quite possible for it to be variable. Thus, it is possible that the spacing of the pins located in the center of the panel differs from that of the pins located at the periphery or simply that areas of the panel have pins 32 having a different spacing.
- the spacing between the pins 32 is such that the pins are positioned to be aligned in the form of a grid or to be staggered.
- the height of the spikes 32 is an adjustment variable.
- the studs do not need to extend the full thickness of the panel. Indeed, the operation of the present invention is based on the presence of pins or rods which make it possible to increase the friction and the holding of the flakes.
- spikes 32 having a length at least equal to 25% of the depth of the panel, as shown in FIG. 5, have an effect on settlement.
- the spikes have a length equal to at least 50%, or even 75% and even more preferably 100% of the depth.
- the advantage of the pins and their distribution in the panel is to increase the hold of the flakes in the housing without having to partition said housing, thus avoiding intermediate settlements.
- the pins are used to obtain a better hold of the flakes by increasing the friction that there may be between the flakes among themselves and between the flakes and the structure of the panel.
- the spacing between the pins allows the snowflakes to have freedom of movement.
- the combination of the spikes and the spacing between the spikes allow the flakes to have a hold in the panel limiting the compaction and without partitioning said panel.
- These retention means 30 are arranged in the panel before it is filled with the insulating material.
- the pins 32 are directly attached to the rear plate 16 as shown in Figure 6. Each pin 32 is then attached to the plate by gluing.
- the plate is optionally marked with a plurality of blind holes 160 each corresponding to the position of a pin. Each pin is then placed in a hole and then glued.
- each pin 32 is provided with a fixing head 32a allowing said pin to be screwed onto the rear plate as shown in Figure 7.
- the pins 32 according to this first embodiment are fixed to the rear plate 16 before or after its assembly with the frame 12 but before filling with the insulating material.
- the pins 32 are fixed to the panel via a structure 40.
- This structure 40 is in the form of a sheet 41 from which the pins extend.
- These spikes 32 are elements attached to the sheet 41 but may be of material/be integral with the sheet 41 .
- the pins 32 and the sheet 41 form the structure can be made of the same material or of a different material.
- the pins 32 and the sheet 41 form the structure can be made of the same material or of a different material.
- the material of the pins and of the sheet is identical. This allows, in the case of wood or metal, to produce the sheet and barb assembly by machining, whereas in the case of plastic, injection molding can be used. Of course, all the possible methods making it possible to obtain this set sheet - pins can be used.
- the sheet 41 provided with the pins 32 is fixed to the rear plate 16 as shown in Figure 8.
- This fixing allows the sheet to remain in place regardless of the orientation of the panel.
- This fixing can be done by nailing, stapling, gluing, screwing or by a click system.
- the flexible sheet 41 from which the pins extend is perforated, that is to say it comprises a multitude of openings 42. These openings 42 are made to first lighten the structure 40. Indeed, this flexible sheet 41 brings unnecessary additional weight.
- this openwork makes it possible to limit the influence of the flexible sheet 41 on the thermal performance. Indeed, it is possible that the material used for the flexible sheet 41 is not a good thermal insulator so as to degrade the thermal performance of the insulation board. To limit this degradation, the openings 42 make it possible to limit the quantity of inefficient material.
- the pins 32 and the flexible sheet 41 are fixed to the rear plate, before or after its assembly with the frame, but before filling with the insulating material.
- the pins 32 of the retention means 30 are fixed via a double structure 40'.
- This double structure 40' comprises two flexible sheets 41' between which pins 32 extend as seen in Figures 10a and 10b. These two sheets are preferably parallel to each other.
- the flexible sheets 41 'and the pins 32 can be made of different materials: wood, plastic, metal or be made of the same material, be made of material or be attached to each other by gluing, nailing, stapling, screwing, snapping or by any other means.
- the flexible sheet not fixed or in contact with the rear plate is perforated, that is to say comprises multiple openings allowing the insulating material to be inserted between the two flexible sheets 41 '.
- this openwork is also made on the flexible sheet 41′ fixed or in contact with the rear plate.
- This opening makes it possible to limit the weight of the 41' flexible sheets but also to make it possible to limit the degradation of performance. Indeed, with a full flexible sheet 41' in contact with the rear plate, there is the risk of a deterioration in the performance of the panel, this flexible sheet 41' being made of a material which itself has poor thermal performance.
- the two flexible sheets 41' are perforated as shown in FIG. 11, that is to say comprise openings, it is necessary that this perforation does not disturb the arrangement of the pins 32.
- the two flexible sheets 41' are preferably perforated in a similar way so that the openings of the two flexible sheets 41' face each other in pairs.
- the two flexible sheets 41′ are each replaced by a grid formed of intersecting wires as shown in FIG. 12. These two grids are interconnected by the pins, these extending from the wires forming the grids.
- the two flexible leaves and the pins form a frame like a trellis.
- This configuration in the form of a grid advantageously makes it possible to limit the quantity of material liable to degrade the performance of the panel while allowing good filling of the panel with the insulating material.
- part of the pins 32 extend to be in contact with the two sheets or grids and that the other part of the pins are not.
- barbs extending from one or the other of the sheets or grids without being in contact with the two sheets or grids.
- the pins in contact with the two sheets or grids have an additional, structural function, which consists in maintaining the two sheets or grids spaced from each other.
- the pins can be fixed on the back plate and on the front plate or only on the front plate.
