Definitions

  • the invention is directed to a self-supporting light-weight insulation panel for use as a construction panel in buildings, a use of such insulation panel and an arrangement comprising such insulation panel and a support structure, to which the insulation panel is fastened.
  • Self-supporting insulation panels of this kind are used as construction panels in buildings. Typically these panels have an enclosure defined by two rigid planar faces - a back face and a front face, which are connected by at least two longitudinal side faces - a right face and a left face. Such enclosure is manufactured from rigid material, in most cases of metal or wood. The enclosure provides for the self-support characteristic of the panel. In order to enhance the thermal insulation between the two planar faces the hollow interior of the enclosure is filled with insulation material. The material used for the insulation purposes ranges from mineral fibres to foam. In some cases also bulk material is used for filling the hollow interior of such housing. From prior art it is also known, to integrate longitudinal reinforcement members within the insulation material. Self-supporting insulation panels of this kind are disclosed for example in US 4,981,003 and US 4,844,975 .
  • the prior art insulation panels are used for light-weight wall constructions for buildings or to provide insulated walls for temperature-regulated rooms, such like walk-in coolers or freezers.
  • the reinforcement members are typically fastened to at least one face - the front face or the back face - of the housing.
  • the reinforcement members are only attached to one face and that these do not contact the other face in order to omit cold bridges by way of the reinforcement members, which are typically manufactured from sheet metal.
  • the reinforcement members are completely integrated into the insulating body and therefore spaced from both planar faces - the front face and the back face - of the insulating body.
  • a further self-supporting roof panel is disclosed in BE 898 919 .
  • This prior art self-supporting insulation panel comprises an insulating body manufactured as foamed material, which could be a polyurethane (PU)-foam. Elongate members are integrated into the foam with a small distance to the longitudinal side faces. These are arranged being directed in the longitudinal extension of the insulating body. These elongate members extend through the full length of the insulating body.
  • This prior art panel further comprises at its bottom end a wooden board, which is arranged in a cutout section of the insulating body in a transverse direction to the extension of the elongate member arranged flush with the transverse side face of the insulating body.
  • the wooden board In order to hold in place the wooden board this is fastened either to the elongate member or to an L-shaped crossbar integrated into the PU-foam and linking the two elongate members.
  • the longer leg of such crossbar is arranged parallel to the two planar faces of the insulating body.
  • the crossbar is arranged with its longer leg to be approximately in the middle of the width of the wooden board.
  • the elongate members and the crossbar are steel profiles.
  • the wooden board is used as mounting base to fasten battens thereon, which extend in the direction of the elongate members.
  • the wooden board is thus used to receive the shear load resulting from tiles resting on roof laths mounted on the battens.
  • a second wooden board may be arranged at the top end of the insulation panel in the same manner.
  • the wooden board does not contact the elongate members. Therefore these and the crossbars are concealed within the insulating body, making it difficult to properly identify, where to apply a screw to fasten the wooden board to its mounting base. This mounting is vital, because otherwise the shear forces received by the wooden board would not be transferred into the elongate members.
  • US 3,773,604 A discloses a light-weight structural panel for cryogenic applications, which comprises a core having an upper and a lower face and at least one layer formed by a series of balsa beams in spaced relation and a series of slabs of synthetic thermal insulating material disposed in the spacings in between.
  • the thermal insulating material may be, among others, a foam plastic material.
  • One embodiment shows a three-layer structure, where the beams in neighbouring layers are displaced by 60° with respect to each other.
  • FR 2 292 817 A1 discloses a construction panel with a series of elongate wooden members having a small cross-section and being arranged in parallel on a first surface of the panel. These wooden members are capable of supporting fasteners like nails, hooks or the like. They are embedded in a isolating foam material.
  • the second surface of the panel is formed by a load-bearing plate, which may also be made of wood.
  • the panel may be enclosed by a wooden frame.
  • intermediate stiffening members may be disposed between the plate and the wooden members, arranged perpendicular to the wooden members.
  • GB 556,460 A discloses a panel member, which may be used in vehicle structures or for floorboards, bulkheads or the like.
  • the panel member comprises two sheets of fibrous material separated by stringers of fibrous material, all of which are impregnated and/or bonded with synthetic resins and consolidated under heat and pressure.
  • Two sets of stringers may be placed perpendicular to each other and may form a series of cells, which may optionally be filled with low density material like synthetic foam.
  • FR 2 180 826 discloses a structural building panel with a core and a pair of cover elements fixed to the core.
  • the core comprises a plurality of strips e.g. made of wood. Two sets of strips are disposed so that the strips in each set are in parallel to each other and at an angle to the other set of strips. Thus, the two sets support each other in an orientation perpendicular to the cover when the cover is fixed to the core.
  • Each strip may have a series of notches into which other strips are inserted to establish a secure connection.
  • a self-supporting insulation panel according to the invention does not need any rigid facings enclosing a cavity, in which an insulating material is introduced.
  • structural beams are utilized. Typically these are designed as rafters/joists/beams. The structural beams are laid out in such a manner that they provide the load-bearing capacity of the insulation panel and that these also provide for the principal self-supporting characteristic of the panel in the direction of the longitudinal extension of the beams.
  • the load-bearing capacity of the insulation panel means, that the full load of the panel and possible weight it supports is carried by the structural beams and transferred into a bearing or a support, to which the panel is fastened and/or resting on. Due to this concept no facings and no enclosure is needed to provide for the major load-bearing capacity. Therefore, these may be made up of, if at all, also by flexible members, for example multi-foil facings. Since the structural beams provide the major load-bearing capacity, all other members incorporated into the insulation panel do not need to comply with these requirements of the panel. Of course, further members of the insulation panel add to the carrying capacity, but it remains with the structural beams to provide the load-bearing capacity or at least the major load-bearing capacity. Since the beams are arranged with distance to one typically planar face of the insulating body, the beams do not result in any cold bridges.
  • the structural beams are integrated in and connected to the insulating body.
  • the integration of the structural beams is not complete since the beam may protrude with a certain portion of its height from the first planar face of the insulating body or it may be arranged with at least part of one of its faces flush with this first planar face of the insulating body.
  • the connection of the structural beams to the insulating body may be achieved in many ways. When using a polymer foam, such as polyurethane foam, as insulating body, the connection may be achieved by the intrinsic forces of the foaming material during the production process. The intrinsic forces are the bonding forces of the foaming material prior to its completely cured state. These bonding forces may be used to provide an adhesive connection between the structural beams and the insulating body.
  • the structural beams are positioned in place in a mould or on a conveyor (if manufactured in a continuous production line), when the foaming material is introduced resp. therein or thereon for expanding and curing. It is also possible to use an adhesive in order to bond the beams to the insulating body or even to use mechanical connection members. Depending on the rigidity of the material of the insulating body the beams may also be held in place simply by a clamping force resulting from the insulating body and applied to the beams being integrated into the insulating body. Also a combination of these connection types is possible.
  • the concept of the claimed self-supporting insulation panel allows, that it is possible to manufacture the insulating body as one single member. This enhances the structural integrity of the panel in particular in transverse direction to the extension of the structural beams.
  • the structural beams are designed to provide a mounting base for a fastener, in particular a mechanical fastener, either to fasten something to the panel or to fasten the panel to something else, for example a support.
  • the design of the structural beams is in such a way that, when using for example a screw as a fastener, its fixing (threaded) section may completely be introduced into the beam as far as the fixing section protrudes from the support. This implies that the structural beams have a certain height and a certain width in order to accommodate the fixing section of such fastener.
  • the benefit of this design of the structural beams is, that these may be mounted to a support structure without needing to drive fasteners through the complete panel.
  • fasteners are introduced into the side of the beams being arranged flush with the insulating body or protruding therefrom. In most cases such fastener will be driven into a structural beam in the direction of its height.
  • This fastener is fixed to the support structure either directly or indirectly, e.g. by means of a metal profile. In case the structural beam protrudes from the insulating body such fastener may also be introduced into one of the protruding sections of the other sides of the beam.
  • such insulation panel is mechanically fastened to a support structure by using a hook-type fastener, which is introduced into the insulating body next to a structural beam in such a manner, that the hook section rests on the face of the structural beam, which is arranged with a distance to the second face of the insulating body.
  • the fastening section of such hook-like fastener is then fixed to a support structure.
  • the self-supporting light-weight insulation panel according to the invention carries load-receiving members at its face, from which the structural beams are spaced,.
  • load-receiving members may be of the kind of battens being arranged in the transverse direction to the direction of the structural beams.
  • the load-receiving members are arranged parallel or substantially parallel to each other and are spaced with a distance from each other.
  • the load-receiving members are also integrated into the insulating body in the same manner as the structural beams are integrated into the insulating body.
  • the set of load-receiving members typically comprises at least three members. At least one of these members, preferably though the majority of the members - if not all - are arranged with their longitudinal side faces with a distance to both side faces of the insulating body.
  • the intention with this measure is that these load-receiving members are integrated in and in contact with the insulating body at least at three of their sides. Due to the number of load-receiving members and in particular their integration into the insulating body, shear forces are effectively absorbed, without needing to have the load-receiving members be rigidly connected to the structural beams.
  • Load introduced into the load-receiving members which load may for example be the weight of roof tiles or other roof coverings, will be distributed through the insulating body, collected and deflected by the structural beams into a supporting structure, to which the beams are fastened to and/or resting on.
  • This self-supporting insulation panel is made up of number of individual structural beams, a number of load-receiving members arranged oblique or perpendicular to the longitudinal extension of the structural beams and the insulating body, to which the structural beams and the load-receiving members are connected to.
  • the insulating body has besides its insulating functionality also a structural functionality. This also comprises the ability of the insulating body to absorb shear forces introduced through the load-receiving members.
  • the load-receiving members are arranged to be perpendicular to the direction of extension of the structural beams.
  • Such arrangement is preferred with an insulation panel of basically rectangular or square shape. Should such panel have another geometry, for example a trapezoid or a triangle-like geometry, then the load-receiving members may also be arranged with another angle in respect to the longitudinal extension of the structural beams.
  • the load-receiving members are not in contact with the structural beams.
  • the set of structural beams and the set of load-receiving members are spaced in the direction of the thickness of the insulating body from each other by insulating material defining the insulating body.
  • the set of load-receiving members are in contact with the structural beams.
  • a spacer between the areas of contact.
  • Such spacer is preferably manufactured from a material having a higher insulation capacity than the material the structural beams and/or the load-receiving members are made of.
  • spacers may be of plastic or of any appropriate foamed material.
  • the load distribution from the load-receiving members into the structural beams is better if the load-receiving members are in contact with the structural beams - directly or by way of an intersected spacer.
  • the side faces of the insulating body may be finished for a joint fitting arrangement with an adjacent insulation panel.
  • Another advantage of the invention may be encountered.
  • the joint fitting arrangement may easily be adapted to the insulating body, in particular in a certain variety of geometries. In prior art panels having rigid longitudinal side faces as part of an enclosure, the panel cannot be provided that easily with such a joint fitting arrangement.
  • the structural beams extend substantially over the full length of the insulating body. It is also possible that the structural beams are designed to be longer than the full length of the insulating body and that they protrude from one or both of the side faces of the insulating body. In this case, these sections of the structural beams may be used as connection or fastening parts or as parts of the beams, which are connected to a counter bearing, for example a purlin or a rafter.
  • a self-supporting insulation panel 1 comprises in the embodiment depicted in figure 1 a set of elongated structural beams 2, which set of structural beams comprises the number of two beams 2.
  • the beams 2 of the depicted embodiment have a rectangular cross-sectional geometry as to be seen in the transverse side face 3 of the perspective view of figure 2 .
  • the beams 2 are manufactured from wood.
  • the structural beams 2 may therefore be referred to as rafters/joists/beams. In the depicted embodiment this implies that the structural beams have a width and a height sufficient to embed that part of a treaded section of a fastening screw, which is intended to be used for mounting the panel 1 to a support structure.
  • the insulation panel 1 further comprises an insulating body 4, which in this embodiment is a polymer foam body, in particular a polyurethane (PU) foam body.

  • the load-bearing direction is in the direction of the longitudinal extension of the structural beams 2.
  • the structural beams 2 are arranged parallel and with distance to each other. The distance at which the structural beams 2 are spaced from each other will be designed in regard of the load, which this insulation panel 1 needs to carry or withstand. It will be understood that implementing more beams with a smaller distance to each other will enhance the load-bearing capacity of the panel.
  • the structural beams are spaced from the longitudinal side faces 5, 6 of the insulating body 4.
  • the insulating body 4 has a first planar face 7 and a second planar face 8 on the opposite side thereof.
  • the self-supporting insulation panel 1 is manufactured as a flat body. It is also possible to design such self-supporting insulation panel with a curvature.
  • the structural beams 2 of this embodiment are arranged with one of their small longitudinal side faces 3.1 in a flush arrangement with the planar face 7 of the insulating body 4.
  • the side face 3.2 opposite to the side face 7 of the beams 2 is arranged with a suitable distance from the planar face 8 of the insulating body 4 in order to avoid a cold bridge between the two faces 7, 8 of the insulating body 4.
  • the insulating body 4 may be manufactured as one single body, which is the fact with this embodiment. This is of benefit in respect of an enhanced load distribution and structural integrity of the insulation panel 1.
  • the polymer foam making up the insulating body 4 of the insulation panel 1 shows a rigidity, which may also be addressed as stiffness.
  • Both elements - the structural beams 2 and the insulating body 4 - are connected to each other, which is necessary for the purposes of the insulation panel 1.
  • Various means may be applied in order to connect the structural beams 2 with the insulating body 4.
  • the structural beams 2 By integrating the structural beams 2 at least in part into the insulating body 4 a sufficient surface area is provided for applying easy conductible connecting methods and shear forces will be distributed over the complete contact area.
  • the insulating body 4 is foamed around the structural beams 2.
  • the intrinsic adhesion properties of the PU-foaming material during the production process are used to adhere the insulating body 4 to the faces of the structural beams 2 being in contact with the insulating body 4.
  • other measures may be utilized, such as applying an adhesive to attach the insulating body 4 to the structural beams 2 or a combination of different adhesive connecting methods.
  • the longitudinal side faces 5, 6 of the insulating body 4 show a shiplapped finishing. This is used for a joint fitting arrangement of the depicted insulation panel 1 with a second one, both arranged with their longitudinal side faces in contact with the side face shown.
  • the insulation panel 1 comprises a set of load-receiving members 9.

  • FIG. 3 shows in a perspective view an insulation panel 13 according to another embodiment.
  • the insulation panel 13 as depicted in figure 3 is identical to the insulation panel 1 of figures 1 and 2 . Therefore, these descriptions also apply to the insulation panel 13.

  • the beams 2.1 are integrated into the insulating body 4.1 by about 75% of their height. This means, that 25% of the height of the structural beams 2.1 protrudes from the planar back-face of the insulating body 4.1.

  • the insulation panel 14 differs from the insulation panel 1 in the geometry of the cross-section of its load-receiving members 9.1. Whereas the load-receiving members 9 of the insulation panel 1 show a rectangular cross-section and are arranged with one of their wider faces parallel to the planar faces of the insulating body 4, the load-receiving members 9.1 show a T-beam-like cross-section. Also other profiled load-receiving members may be utilised, for example with an L-cross-sectional geometry.
  • Such geometry like for example T- or L-shaped geometries in the cross-section increases the contact surface of the load-receiving members 9.1 with the insulating body 4.2. With such increased contact area, in which the load-receiving members 9.1 are connected to the insulating body 4.2, this panel 14 will even resist higher shear forces introduced into the load-receiving members 9.1.

It will be understood, that the different geometries of the openings are depicted as examples and that typically one type of opening will most likely be used throughout the longitudinal extension of a beam 2.4 and/or a load-receiving member 9.3. Of course, also openings with a different geometry as the depicted ones may be utilized. The major load bearing capacity and the principle self-supporting characteristic of the insulation panel will be provided by the structural beams 2.4.
  • Figure 7 by way of an example shows a number of sections of load-receiving members differing in their cross-sectional geometry.

The examples in figure 7 show, that a wide variety of load-receiving members as to their cross-sectional geometry may be used depending on the aspects they are utilized for.
  • the structural beams and, if used, the load-receiving members may be utilized as fastening base, into which fasteners, for example nails or screws may be introduced either to fasten a certain part to the insulation panel itself or to fasten the insulation panel to some other construction, for example to rafters or purlins in a pitched roof.

  • This system is preferably equipped with a non-stick surface, for example a certain structure of the surfaces or a release spray supplied from nozzles at the entrance of the laminator.
  • the laminator may be equipped with a top conveyor belt.
  • the conveyor belt will be constructed in such a manner that there are grooves, in which the structural beams can be inserted. The depth of these grooves will be dimensioned equivalent to the protrusion of the structural beams from the face of the insulating body.
  • planar faces of the insulating body be covered with a flexible facing for example a multi-foil laminate, this may be applied during the foaming process. Then the facings will be adhered to the insulating body due to the intrinsic forces of the foaming material during the production process.
  • a flexible facing for example a multi-foil laminate
  • insulating body being a PU foam
  • other materials may be used to make up the insulating body, in particular other polymeric foams such as expanded polystyrene (EPS), polyisocyanurate (PIR) foam or phenol formaldehyde foam (PF).
  • EPS expanded polystyrene
  • PIR polyisocyanurate
  • PF phenol formaldehyde foam
