Description

Insulation element.

The present invention relates to an insulation element.

Insulating elements in the form of insulating plates, for example for the post-insulating of walls, floors, ceilings and roofs, are already known and can for instance mainly be composed of a hard foam plate, such as a polyurethane, polyisocyanurate or polystyrene plate, which for example has aluminum coatings on both sides. Insulation plates are known, for example, from WO 2012/104067, EP 2 316 641, NL 2012181, DE 20 2005 011 630 UI and DE 20 2009 001 352 UI. Such insulation is usually finished on the visible side with plasterboard plates or other plate materials on a framework of, for example, wood or aluminum. Any cables, such as electrical cables, are best placed between the framework in the cavity between insulation material and sheet material before the finish is placed. In addition, insulating finishing plates are widely known and can for instance mainly be built up from a hard foam plate, such as from polyurethane, polyisocyanurate or polystyrene plate, and a visible side with plasterboard plate or another plate material. Any cables, such as electrical cables, are best fitted at the rear of the insulation element, in the load-bearing wall or in the insulation material. The subsequent installation of pipes requires cutting the finish along the entire path of the pipe to be provided and restoring the visible side again. In such cases, the insulation material must be removed along the entire track. It is of course also possible to work with surface-mounted channels. However, the latter are less attractive in most cases.

Insulation elements in the form of self-supporting elements, for example for forming a roof construction, are also widely known and can for instance mainly be built up from a base plate with ribs arranged thereon, wherein insulating material is arranged between these ribs. Self-supporting insulating elements are known, for example, from EP 2 273 024. With such insulating elements, the base plate can per se form the visible side, for example the inward-facing side in the case of a roof construction. In the case of these insulating elements, pipes can only be laid afterwards, either by construction or by cutting the base plate over the entire path of the pipe to be provided and restoring the visible side again.

For example, from US 4,163,348 and CN 104032920 A, it is known per se to use honeycomb filling in partitions, with a view to obtaining a rigid separation of limited weight. With the same point of view, it is known from US 7,707,799 B2 and WO 2013/060308 to integrate a honeycomb structure into the insulation material of a self-supporting insulating element.

From US 8,387,747 B2 and EP 1 840 287, it is then known to use an open honeycomb structure for creating a certain sound absorption.

From WO 2013/120148 it is known to use a closed honeycomb made of aluminum as a base plate for fire-resistant insulation in ships. The visible side is formed by the insulation.

The present invention is defined in the claims and relates to the further described second aspect.

It is an object of the present invention to provide an insulating element that makes it possible to provide pipes behind the visible side in a simpler manner. To this end, the present disclosure, according to its first independent aspect, describes an insulating element, said insulating element comprising at least one base plate and insulating material, characterized in that the insulating element between the base plate and the insulating material further comprises a, preferably separate intermediate layer with a cellular structure. Through channels can be provided in the intermediate layer for pipes without the base plate having to be opened along the entire desired path of the pipe. For example, it is sufficient to make an opening at the beginning and the end of the web and to insert a feed-through channel through the cellular structure of the intermediate layer on the basis of a tool, such as a needle or heated thread. Such tools are known, for example, from FR 2 789 239. The aforementioned openings are generally nevertheless required for placing switches, sockets or other tapping points, such that on the basis of the insulating element it is possible to provide a line behind the base plate without unnecessary have to make openings. The insulating element of the invention thus offers a ready-made solution for, for example, a retaining wall.

Preferably, the aforementioned intermediate layer extends at least over a thickness between 1.5 cm and 4 cm. Such a thickness makes it possible to pass through the usual pipes without too much limiting the insulation value of the insulation element as a whole. It is noted here that the cell filling can in itself contribute to the insulation value of the insulation element, even in the case of air.

Preferably, the cellular structure of the intermediate layer is at least coarser than the cellular structure of the aforementioned insulating material. The coarser cell structure offers less resistance when puncturing the channels, since fewer cell walls need to be punctured or fused or the like. It is preferably a cell structure with an average cell diameter of at least 5 millimeters and more preferably of at least 1 centimeter. Preferably it concerns elongated cells, the height of the cells being at least 2 times the diameter.

Preferably, the cellular structure of the intermediate layer substantially comprises cells that extend uninterruptedly over substantially the full thickness of said intermediate layer. Preferably, they are prismatic cells which extend transversely, preferably perpendicularly or substantially perpendicularly, to the base plate with their height direction. Such orientation retains a sufficient firmness, for example, tightness of the insulating element;

The cellular structure is preferably substantially or completely composed of prismatic cells which extend transversely to the base plate with their height direction, and wherein the base surface has at least two pairs of parallel sides. Preferably, a first pair of said parallel sides extends in the width direction of the isolation element, while a second pair of said parallel sides extends in the height direction of the isolation element. In this way it becomes easy to insert horizontal or vertical channels through the cellular structure. According to the most preferred embodiment, the prismatic cells extend perpendicularly or substantially perpendicularly to the base plate with their height direction, and the base is a quadrangle or, more preferably, a square.

The above makes clear that the aforementioned intermediate layer preferably has a honeycomb structure, namely prismatic with a hexagonal base surface, or another grid structure, preferably prismatic with a square base surface.

The intermediate layer preferably consists essentially of paper, cardboard or a plastic, such as polypropylene or polystyrene, more particularly, at least the cell walls consist of paper, cardboard, polypropylene or polystyrene. Through such a cellular structure or cell walls, channels can easily be provided by means of a needle, for example in the case of paper and cardboard, or by means of a heated wire, for example in the case of polystyrene.

A special possibility for the intermediate layer is the use of the screen structures which are known per se from EP 1 165 310, wherein such structure is manufactured from leaf-shaped material on the basis of a continuous production process.

It is clear that the aforementioned base plate preferably forms a visible side of the insulating element or that the aforementioned base plate is intended to be finished to form a visible side.

Preferably, the aforementioned base plate comprises a plasterboard board, a plasterboard or cement fiber board, or a wood particle board, such as a wood chip board, an OSB board (Oriented Strand Board) or an MDF / HDF board (Medium or High Density Fiberboard).

Preferably, the aforementioned insulation material is hard foam. It is especially with these insulation materials that the passage of pipes is problematic, since they are not or hardly compressible. The aforementioned insulation material preferably relates to polyurethane (PU), poyl isocyanurate (PIR), expanded or extruded polystyrene or phenol isolation.

According to a variant, the aforementioned insulating material comprises a mat-shaped insulating material, preferably mineral wool, for example with glass wool or rock wool. It is also possible to work with wood wool, flax wool, sheep wool, feathers, straw and the like. In the case of mineral wool, a significant fire-resistant and fire-retardant effect is achieved. For the insulation material, a cellulose-based insulation material or insulation material based on wood fiber can also be used. Cellulose or wood fiber-based insulation materials are known for their good acoustic insulation value, moreover they also show an acceptable to very good thermal insulation value.

It is of course possible that the insulating element comprises several layers of insulating material. According to a special example thereof, the insulation material consists essentially of rigid foam, but the insulation element on the opposite side of the base plate has a mat-shaped insulation blanket. Similar to in NL 2012181, unevenness can be absorbed using the matt-shaped insulation blanket, for example when placed against an impure wall, while a good insulation value is achieved with the rigid foam. Preferably, the rigid foam in this case is polyisocyanurate.

Preferably, the aforementioned cells are only filled with air or another, possibly insulating gas, such as a pentane based gas. If the cells are nevertheless filled with a material, it is preferably a material that can flow at the use temperature, either a gel-shaped, a liquid or a powdered material, such that this material can easily be removed when the channels are plugged and, preferably, flows out by itself. It can also be a material that becomes liquid or gaseous when the channels are plugged, for example because the pressure in the cells drops or because the temperature in the cells increases, for example when a heated needle or thread is used for the plugging of the channels. Polystyrene granules, perlite granules or vermiculite granules can be used as powdered material. These powders lead to an additional insulation value. Preferably, the aforementioned cells are free of solid and liquid material.

In another preferred variant, the cells are filled with a compressible insulating material, such as a cellulose-based insulating material and / or a fiberglass-based insulating material. This may, for example, involve a blow-in insulation. The use of a compressible insulating material makes it possible to insert channels by pushing the relevant insulating material sideways by means of the tool used herein and / or by means of the conduit itself to be fed through.

The isolation element of the invention can be realized according to various concrete possibilities, three important possibilities of which are mentioned below, without being exhaustive.

According to a first important possibility, the insulating element of the invention relates to an insulating finishing plate for fixing to walls, floors, ceilings or roof structure, or to a timber or aluminum frame to finish walls, partition walls, floors or ceilings. The base plate is then, preferably, directed inwards and forms the visible side, or the basis for the visible side.

According to a second important possibility, the insulation element is a self-supporting insulation element. Such a self-supporting element furthermore preferably comprises one or more ribs between which said insulating material is situated. These ribs are preferably directly attached to the base plate. This may be a scaled-up roof element, or a so-called sandwich element, wherein a plate material is also applied to the insulating material on the opposite side of the base plate.

According to a third important possibility, the insulating element relates to an element for forming partitions or partitions. In such a case, it preferably concerns an element which is provided with a base plate on both opposite sides. These then always form a visible side. Preferably, an intermediate layer with a cellular structure is located under both base plates. According to the most preferred embodiment, such an element, viewed in thickness, is completely symmetrical.

According to a special variant of the present disclosure, the intermediate layer is made in one piece with the insulating material, this insulating material consisting of hard foam and this hard foam being made against the base plate with a coarser cell structure than in the rest of the insulating material. The cell structure of the intermediate layer is preferably provided with a cell diameter that is on average ten or a hundred times larger than the average cell diameter of the actual insulation material.

With the same point of view as in the first aspect, the present invention as defined in the claims, according to a second independent aspect, also relates to an insulating element, said insulating element comprising at least one base plate and insulating material, characterized in that the insulating element The element between the base plate and the insulating material further comprises a, preferably separate, intermediate layer with preformed channels, the cross-section of said channels having at least one side formed by a material different from the global material of the intermediate layer. The respective channels preferably extend according to at least one of the main directions of the insulation element in question, preferably at least in the longitudinal direction. According to an alternative, the channels can extend in two directions situated transversely to each other, for instance both substantially transversely and substantially along, so that the channels form a grid pattern in the relevant intermediate layer. The relevant channels can be used as lead-through channels for pipes without the base plate having to be opened along the entire desired path of the pipe. In the case of channels extending exclusively or substantially in the longitudinal direction, a passage in transverse direction must be realized on the basis of a tool as described with reference to the first aspect.

Preferably, the aforementioned intermediate layer has a foamed structure. In such a case, the passage of pipes at positions which at least partially fall outside the preformed channels can be easily carried out.

The intermediate layer preferably consists essentially of polystyrene, preferably polystyrene foam such as XPS (extruded polystyrene) or EPS (expanded polystyrene).

The aforementioned channels are preferably provided by means of a milling operation in the material of the aforementioned intermediate layer.

The channels of the insulation element from the second aspect can also find a different application than merely the passage of pipes and cables. For example, they can also form air ducts, for example for ventilation or convective heat transfer. In case the channels are intended for the passage of pipes and / or cables, they can be filled with a gas or other material, such as with the materials mentioned in the context of the first aspect for the filling of the cells mentioned therein.

The channels of the insulating element are preferably designed with a rectangular or square cross-section, one side of which is preferably formed by a material different from the global material of the intermediate layer, for example by the material of the aforementioned base plate. It is of course not inconceivable that channels would be chosen which have a different cross section, such as a hexagonal section or a circular section. According to the invention, however, the cross-section has at least one side which is formed by a material different from the global material of the intermediate layer, for example by the material of the aforementioned base plate, in other words through the rear side of the base plate.

The intermediate layer preferably comprises a plurality of parallel channels, the mutual distance of which is chosen such that a branch opening always partially opens at least one of these channels. A good choice here is a mutual distance between the center lines of two adjacent channels of 10 centimeters or less, and even better of 7 centimeters or less.

Preferably, the aforementioned channels extend substantially, or globally, in a straight line. When the channels extend other than straight, they preferably have a path with a center line that deviates only to a limited extent from a straight line, namely with a deviation smaller than the width, or smaller than half the width of the channel in question.

It is self-evident that the isolation element of the second aspect can also be realized according to various concrete possibilities, inter alia according to the three important possibilities mentioned on the basis of the first aspect, wherein the cell structure is then exchanged with the preformed channels of the second aspect. For example, according to the third important possibility, the insulating element then relates to an element for forming partitions or partitions. In such a case, it preferably concerns an element which is provided with a base plate on both opposite sides. These then always form a visible side. Preferably, there is an intermediate layer with preformed channels under both base plates. According to the most preferred embodiment, such an element, viewed in thickness, is completely symmetrical, in other words mirror-symmetrical.

In order to better demonstrate the characteristics of the invention, a few preferred embodiments are described below with reference to the following drawings, by way of example and without any limiting character, in which: figure 1 represents an isolation element with the characteristics of the first aspect of the revelation; figure 2 represents a section on a larger scale according to the line II-II shown in figure 1; figure 3 represents on a larger scale a cut-away view according to the arrow F3 shown in figure 1; figures 4 and 5 represent variants in a view similar to that of figure 2; figure 6 represents another isolation element with the features of the first aspect of the disclosure in perspective; figure 7 represents a section on a larger scale according to line VII-VII shown in figure 6; figures 8 and 9 show variants in a similar view; and Figures 10 and 11 represent views in isolation similar to those of Figures 6 and 7, respectively, of an insulating element with the features of the second aspect of the invention as defined in the claims.

Figure 1 again shows an insulating element 1, in this case an insulating finishing plate.

Figure 2 clearly shows that the insulation element 1 comprises a base plate 2, in this example in the form of a plasterboard, and insulation material 3, in this case hard foam such as polyisocyanurate.

Figure 3 shows that there is a separate intermediate layer 4 with a cellular structure between the base plate 2 and the insulating material 3. The intermediate layer 4 has a grid structure 5 that is built up of prismatic cells 6. In this case, the cells 6 have a hexagonal base and form a honeycomb structure. The prismatic cells 6 extend transversely, in this case perpendicularly, to the base plate 2 with their height direction and thereby extend continuously over the full thickness D1 of intermediate layer 4. The average cell diameter as determined by the defined circle C of the said base, is more than one centimeter. The height H1 of the cells is more than 2 centimeters, namely 2.5 to 3 centimeters. The intermediate layer 4 consists of paper or cardboard and the cells 6 are filled with air.

Figure 1 shows in dashed line 7 two circular holes which can be made in the base plate 2 and possibly in the intermediate layer 4. These holes offer space for taps or sockets. The desired path of the line to be provided between the tapping points is shown in dot-and-dash line 8. Behind the base plate 2 or view side 9, a channel can be provided along this path with the aid of a needle, wherein this needle punctures the cell walls 10 of the intermediate layer 4. The insulation material 3 and the back side 11 of the base plate 2 guide the needle in thickness direction, and in other words keep it in the intermediate layer 4. This guide is extremely effective when the insulation material 3 is a hard foam, such as for example polyisocyanurate or polystyrene, regarding.

Figures 1 to 3 further show that on the side 12 of the insulating element opposite the visible side 9 or the base plate 2, a plate-shaped material 13 can also be provided, for example a wood particle plate or a plate material similar or equal to that of the base plate 2 According to a variant, instead of using a plate-shaped material 13, it is possible to work with a layer-shaped coating, for example a cover layer of aluminum foil, or another vapor-tight material.

It is further noted that the base plate 2, in the example a plasterboard plate, has bevels 14 at least at two opposite edges. Such chamfers 14 allow the seams between two adjacent insulation elements 1 to be finished on the basis of a filler.

Figure 4 shows a variant in which a mat-like insulation blanket 15 is applied on the side 12 opposite the base plate 2.

Figure 5 shows another variant in which the insulation element 1 is symmetrical in thickness. In this example, a similar base plate 2 is used on both sides 9, namely a plasterboard or a ceiling plate, and an intermediate layer 4 with cellular structure is present in both gaps between the respective base plates 2 and the insulating material 3. The element shown is suitable for the realization of partitions.

Figures 6 and 7 show an insulation element 1 in the form of a self-supporting element, for example a roof element. The element comprises, in addition to a base plate 2, insulating material 3 and an intermediate layer 4 with cellular structure, one or more ribs 16 between which the insulating material 3 is situated. In this case, three ribs 16 are used, so that two compartments 17 are bounded with insulating material 3. It is clear that it is also possible to work with a single compartment 17, or with three or more compartments 17 which contain insulating material 3. It is also clear that the insulating material 3 and the intermediate layer 4 of the different compartments 17, preferably, as here, are similarly constructed.

The self-supporting element 1 of Figure 6 relates to an open-ended roof element. The flat side of the roof element, which is situated opposite the aforementioned base plate 2, is here open and this open side is mainly formed by the aforementioned insulating material 3. By "open" it is meant that on the relevant side, above the insulating material, no structural components of the roof element. It is of course possible that the insulating material 3 is covered on the open side by a membrane, foil, printing or the like. Such a covering layer is preferably water-retaining and / or vapor-opening, but is not shown here.

It is noted that the roof element of Fig. 6 is shown in abbreviated form and that the length L of a roof element can in practice be several times its width B. The length L can be provided to measure to the roof construction and is preferably between 2 and 8 meters, while the width B of the element depends on the number of compartments 17 that the insulation element 1 has, the width B1 of one compartment 17 is preferably between 35 and 60 centimeters, a width B1 of approximately 40 centimeters being a good value.

The height H of a roof element is dependent on the height H2 of the aforementioned ribs 16 and can herein preferably be chosen between 7 and 35 centimeters.

The aforementioned base plate 2 can be selected from the range of wood chipboard, gypsum board, gypsum fiber board, plywood board, OSB board (Oriented Strand Board) and silicate board. Such a base plate 2 can be provided on its outward-facing side, that is to the inside of the roof construction, with finishing layers, such as with one or more lacquer layers, laminate layers, or with scrapes attached thereto. The base plate 2 may also have fire-retardant and / or water-resistant properties. It is known per se to the person skilled in the art how such properties can be obtained with the base plate materials mentioned here. It is generally assumed that such base plate 2, and in particular chipboard, has no or practically no heat-insulating properties, but it is not excluded that base plates can be used that can offer significant heat insulation.

The aforementioned ribs 16 or squares preferably consist of wood such as pine or pine and preferably cover the entire length L of the roof element. Each rib 16 preferably consists of one piece in the longitudinal direction and preferably has a thickness of 20 to 45 millimeters. Instead of being made in one piece, one or more of the aforementioned ribs 16 in its spring direction can also be assembled from several parts, for example by attaching shorter ribs to each other. Such confirmation can be carried out with a so-called finger joint. For an example of such a technique, reference is made to the aforementioned EP 1 162 050. It is noted that the base plate 2 can also consist of sections welded together.

Figure 8 shows another self-supporting insulating element 1 in which only two ribs 16 are used, so as to form only one compartment 17 with insulating material 3. However, the respective compartment 17 has a width B1 corresponding to that of two compartments 17 of the element of Figure 6, that is to say a width B1 between 70 and 120 centimeters. To achieve a good bending and torsional rigidity, a plate material 13, in this case a wood particle plate, is arranged on the top of the insulating material 3, between the ribs 17. This plate material 13 has a thickness that is smaller than that of the base plate 2.

Figure 9 shows a self-supporting insulation element 1 of the sandwich type. Here, the ribs 16 and the insulating material 3 are located between the base plate 2 and a plate material 13 located on the opposite side, for example a wood particle plate. Furthermore, on the aforementioned opposite side there are dust laths 18 for fixing a roof covering thereon. The insulating element 1 of Fig. 9 is in this case particularly embodied in that the ribs 16 do not extend over the full distance between the base plate 2 and the other plate material 13. This results in an acoustic decoupling between the two plate materials 2-13, as described in EP 2 273 024. However, it is not excluded that the ribs 16 would extend over the full distance between the two plate materials 2-13. According to a further possibility, the insulating element 1 of Fig. 9 can also be designed without ribs 16. In such a case, the insulating material 3 preferably fills the entire space between the plates 2-13, with the exception of the individual layer 4, which then preferably extends continuously between the insulating material 3 and the base plate 2.

It is further noted that, although the examples from the figures represent cell structures consisting of cells 6 of all identical dimensions, it is possible that this cell structure is designed with cells of varying geometry. As the introduction shows, it is not essential that the cells form a honeycomb structure. The base of the cells can have any shape. An interesting embodiment consists of a cell structure with prismatic cells that have a rectangular or square base. The sides of such a base surface are then preferably aligned according to the length L and width B of the insulating element 1.

Figures 10 and 11 again show an insulation element 1 similar to that of Figures 6 and 7, but where, instead of a cellular structure, in accordance with the invention, preformed channels 18 are provided in the aforementioned intermediate layer 4. The channels 18 extend in the longitudinal direction of the insulating element 1. The channels 18, in the present example, have a rectangular cross-section, one side 19 being formed by the rear side 11 of the base plate 2. The height H2 of the cross-section of the channels 18 is in this case of a smaller design than the thickness D1 of the intermediate layer 4. In this way a good guidance of the pipes to be provided in the channels 18 is ensured. Moreover, such an embodiment promotes the adhesion of the actual insulation material 3 or the intermediate layer 4 obtained.

In general, the ratio between the height H2 of the channels 18 and the thickness D1 of the intermediate layer 4 is therefore less than 1 and preferably between 0.5 and 0.9.

In general, the height H2 of the channels 18 is preferably at least 2 centimeters, for example 2.5 to 3 centimeters. In the example, the channels 18 are filled with air.

In the example, the axes of the parallel, adjacent channels 18 are separated by a distance W. This distance W is preferably smaller than 10 centimeters.

The insulating element 1 of figures 10 and 11 comprises polyisocyanurate as insulating material 3, while the material of the intermediate layer 4 is made of polystyrene, more specifically polystyrene foam. The aforementioned channels 18 are formed by milling the aforementioned polystyrene.

It is further noted that, although the examples from the figures show air-filled cell structures and / or channels 18, these cells can also be filled filled, for example by means of an insulating gas, a gel, powdered material or compressible insulating material.

It is clear that the embodiments of figures 1 to 9, if the intermediate layer 4 thereof were to be exchanged with an intermediate layer 4 of the type of figures 10 and 11, also constitute examples of the invention as defined in the conclusions.

The present invention is by no means limited to the embodiments described as examples and shown in the figures, but such an insulating element can be realized in various ways without departing from the scope of the invention as defined by the appended claims.
