Definitions

  • the present invention relates to insulating panels, more particularly to laminated insulating panels comprising a base layer of an insulating material and a cover layer of a mechanically stronger material.
  • Laminated insulating panels for use in roof covering applications are known in the field.
  • the base layer consists of an insulating panel of extruded polystyrene and the cover layer of a hard cement layer adhering thereto.
  • These insulating panels provide the advantage that using a single product both insulation and a weather-resistant finishing layer can be arranged on existing flat roofs.
  • the insulating panels are hooked into each other with a tongue and groove system and the arranged insulating panels remain in place on the flat roof due to their own weight and/or weights arranged on the panels along the edge of the roof. Rainwater seeping through between the joins of the insulating panels flows over the watertight underlying roof structure to the provided discharge points.
  • the base layer is an insulating foam plastic such as polystyrene.
  • the cover layers consist on the one hand of an inorganic cement layer enriched with wood fibres and on the other of a specific type of chipboard.
  • a drawback of the known combined insulating and finishing panels is that they are only suitable for horizontal applications.
  • a laminated insulating panel is provided with an attaching side for placing against a wall, a free side and a number of side walls, and comprises a base layer of an insulating material and a cover layer of a mechanically stronger material, wherein at least one side wall is formed such that in the placed situation one or more spaces adjacent to the attaching side are created between two insulating panels arranged adjacently of each other.
  • the use of such a laminated insulating panel is provided as insulating layer for an upright wall.
  • the use of such a laminated insulating panel is provided as lost formwork for erecting cast structures.
  • a method for placing such a laminated insulating panel against an upright wall, the method comprising the steps of: arranging a first adhesive between the wall and the attaching side; and arranging a second adhesive in the one or more spaces adjacent to the attaching side.
  • at least one of the side walls comprises a second recess, and the method also comprises of arranging a sealing strip in the second recess.
  • a method for arranging a formwork for a cast structure with such a laminated insulating panel comprising the steps of: arranging a sealing means in the one or more spaces adjacent to the attaching side and arranging a connecting means in the second recess.
  • insulating material Deemed to be insulating material are, among others, the insulating materials usual in the building industry, such as materials having a heat conduction coefficient ( ⁇ value) of less than 0.05 to 0.06 W/mK, and preferably those having a heat conduction coefficient ( ⁇ value) of less than 0.035 W/mK.
  • finishing materials are, among others, the finishing materials usual in the building industry, and particularly materials with a sufficient hardness to resist possible impact by small objects, hail, pebbles and the like, and sufficient stiffness to remain planar in vertical position under possible load.
  • the invention is based inter alia on the insight that in vertical applications the laminated insulating panels must be adhered fixedly to the wall on which they are arranged.
  • the invention is moreover based on the insight that it is not desirable for bolts, nails or other connecting pieces to remain visible on the outside of these panels, which also serve as outer wall finishing.
  • an adhesive product which expands significantly after being applied such as for instance a product on the basis of polyurethane foam, can be used at the position of the space created on the attaching side.
  • the use of such products combines a good adhesion of the insulating panels at the position of the edges with thermal sealing of the joins between mutually adjacent insulating panels, whereby possible undesirable cold bridges are avoided at the position of these joins.
  • said side wall comprises a recess extending over the whole periphery of the insulating panel.
  • said at least one side wall has a chamfering of the edge of the insulating panel on the attaching side.
  • At least a part of the attaching side has a structure which improves the adhesion to the wall.
  • the structure of the attaching side enhances the adhesion to an existing wall using a glue or adhesive product, such as for instance a silicone-based product. This is for instance achieved by giving the attaching side a certain roughness or by arranging an uneven pattern thereon.
  • a glue or adhesive product such as for instance a silicone-based product.
  • the structure of the attaching side enables the use of the insulating panels as lost formwork for cast structures, particularly concrete structures, wherein the cast structure has a suitable insulating layer and a finishing layer immediately after curing.
  • the structure of the attaching side enhances the adhesion of the cast material to the base layer.
  • At least one of the side surfaces comprises a recess for receiving a sealing strip.
  • this recess is a groove substantially parallel to an edge of the outer surface of the cover layer.
  • An embodiment of the invention is based inter alia on the insight that the laminated insulating panels must form a watertight whole in some vertical applications, particularly on outside walls, in order to avoid accumulation of water occurring between the insulating panels and the underlying wall.
  • a sealing strip of a watertight material such as for instance rubber or silicone-based adhesive
  • a sealing strip of a watertight material such as for instance rubber or silicone-based adhesive
  • the cover layer consists substantially of cement. This embodiment has the advantage that the cover layer is weather-resistant and is substantially non-expanding.
  • the base layer consists substantially of a foam-like plastic or a plastic foam.
  • said foam-like plastic comprises polystyrene.
  • the base layer consists substantially of cellular glass or a similar mineral foam.
  • An embodiment of the present invention consists of the use of said laminated insulating panels as lost formwork for erecting cast structures. It is an advantage of this use that the cast structure has a suitable insulating layer and a finishing layer immediately after curing.
  • the known laminated insulating panels 100 have substantially an insulating base layer 101 and a cover layer 102 for improving the mechanical properties, particularly on the outer side of the structure to be insulated.
  • FIG. 1 also shows attaching side 103, free side 104 and several side walls 105 .
  • insulating panel 100 according to the invention illustrated in Figure 2 has the same laminated structure.
  • a material which has a sufficiently low thermal (and optionally acoustic) conduction.
  • the material is chosen such that the base layer is sufficiently stiff per se and is suitable for adhering. Diverse types of plastic foam are thus suitable among others. It is moreover advantageous to select a fireproof material.
  • cover layer 102 For the manufacture of cover layer 102 a material is chosen which has the desired hardness and stiffness and can well withstand the atmospheric conditions to be expected. Cement mixtures such as concrete are suitable materials for cover layer 102 because they are weather-resistant and substantially non-expanding. They moreover provide a good fire resistance. Other materials with similar properties can likewise be used, preferably materials with a density of around 2000 kg/m 3 .
  • Side walls 105 are chamfered on attaching side 103 , this forming recesses 106 which create a space or cavity between the wall and insulating base layer 101 when two identical insulating panels 100 are placed adjacently of each other.
  • This cavity allows the use of highly expanding types of adhesive, such as polyurethane foam, which on the one hand ensure an excellent adhesion of insulating panels 100 to the wall and to each other, and on the other form a thermal break of the cold bridges which could occur at the position of the joins. Because all side walls 105 are chamfered in this manner in the illustrated preferred embodiment, the resulting space 106 extends over the whole periphery of insulating panel 100. It is however also possible that not all sides of the panel have such a chamfering.
  • two mutually opposite sides for instance the sides which stand vertically after placing of the panel, have a chamfering extending in each direction up to a distance of about 15 mm from the imaginary edge.
  • two mutually opposite sides for instance the sides which stand vertically after placing of the panel, have a chamfering extending in each direction up to a distance of about 10 mm from the imaginary edge.
  • This preferred embodiment has the advantage of being particularly suitable for the use of the insulating panel as formwork for cast structures, wherein said chamferings form recesses for receiving a known concrete formwork triangular prism.
  • two mutually opposite sides for instance the sides which stand vertically after placing of the panel, have a chamfering extending in each direction up to a distance of about 25 mm from the imaginary edge.
  • This preferred embodiment has the advantage that, when applied to very flat walls, the adhesion to the wall can be improved by increasing the adhesion surface area at the position of the vertical joins.
  • Attaching side 103 has a structure which improves the adhesion to a wall, for instance by an improved adhesion to adhesive products. This effect is obtained by making attaching side 103 sufficiently rough or uneven.
  • the structure is preferably arranged by milling grooves into the base layer in one or more directions. It is also possible to arrange a structure by pressing an optionally heated die or template into the material of the base layer.
  • Fixedly adhering insulating panels 100 to an underlying existing wall preferably takes place with an adhesive product on the basis of silicone. It is advantageous to use an adhesive product which produces a tensile strength of at least about 2.65 MPa.
  • side walls 105 have a recess 107 embodied as a groove for receiving a sealing strip, for instance a sealing strip of rubber.
  • This strip has the purpose of making the entirety of mutually adjacent insulating panels 100 watertight. Thus avoided is that accumulation of water occurs between a wall, in particular an outside wall, and insulating panels 100 arranged thereon.
  • recess 107 is situated about 15 mm from outer wall 104.
  • Recess 107 is preferably a groove of about 15 mm. The form of the groove moreover preferably corresponds with the profile of the sealing strip to be inserted.
  • a judiciously formed sealing strip can be used to realize a pivoting connection.
  • Required for this purpose is that during placing the sealing strip is sufficiently flexible to seal the join completely when the insulating panels are placed in the desired relative position.
  • Such a pivoting connection in the horizontal joins for instance allows placing of insulating panels against a wall which is not perfectly vertical, without undesirable openings thereby occurring between the adjacent insulating panels. It is likewise possible to provide such a pivoting connection in the vertical joins.
  • FIG. 3 illustrates an alternative form for recesses 106 , which are embodied only partially as chamfering. Insulating panel 100 is moreover provided on the free side 104 with an additional layer 108 , which can be arranged because of its specific mechanical properties or for decorative purposes.
  • Figure 4 illustrates the use of insulating panels according to the invention as lost formwork for cast structures.
  • the arrangement of figure 4 shows two mirrored rows of insulating panels according to the invention which are placed opposite each other and form a channel in which concrete can be cast such that an already insulated and finished wall results immediately after curing of the concrete.
  • the channel is bounded by insulating panels according to the invention, only four of which are shown for the sake of simplicity in the figure, and optionally one or more traditional removable formwork plates 401 at the position of the sides where connection to further cast structures is provided.
  • the insulating panels are placed with base layer 101 directed toward the space in which the concrete is cast, and cover layer 102 is directed toward the outer side of the wall.
  • Known fixing means 402 can be used to hold the insulating panels in the correct position during casting of the concrete and during curing.
  • Reinforcement 403 can also be arranged in known manner in the channel, for instance in the form of so-called concrete reinforcing bars, so that the resulting structure will comprise a core of reinforced concrete.
  • This connecting means can comprise a flexible material or a semi-hard or hard material.
  • a flexible material is appropriate when the different insulating panels do not have lie in the same plane as each other, for instance in order to form a slightly curved wall.
  • a hard, straight connection will provide a straight wall with additional formwork strength.
  • recesses 106 are preferably formed such that seepage of concrete liquid into the join is prevented.
  • recesses 106 are formed such that the free space formed by these recesses can be efficiently sealed before casting of the concrete. It can thus be advantageous to provide chamfering of the vertical sides in the insulating panels which, after erection of the insulating panels, forms intermediate spaces which can be efficiently sealed, for instance by arranging a quantity of insulating material in solid form or as sprayed foam. If insulating material is arranged in solid form, it can be very easily cut to size because the space to be filled is suitable for receiving a wedge-shaped piece of material.
  • recesses 106 are formed such that a flat bar can be adhered in efficient manner over the formed seam. After placing the recesses 106 preferably form a wide, shallow groove in which the flat bar can be precisely arranged.
  • the insulating panels according to the invention can equally well be used for horizontal applications such as ceiling formwork.
  • the insulating panels can be placed inter alia on available concrete beams, irrespective of whether these are of the prefabricated type, or be cast in situ.
  • Figure 5 shows a preferred embodiment of the insulating panel according to the invention.
  • Such an insulating panel is for instance 1200 mm wide and 60 mm high, with a thickness depending on the desired application.
  • the thickness of the insulating base layer 101 here substantially determines the insulating capacity of the insulating panel.
  • Cover layer 102 preferably consists substantially of cement.
  • Free side 104 and attaching side 103 are also indicated, wherein attaching side 103 is provided with a structure in the form of a groove pattern which improves the adhesion to the wall.
  • Recesses 106 are embodied as chamferings of the side walls which are vertical when placed.
  • Recess 107 is provided in the vertical joins in order to receive an elastic sealing strip.
  • the components of a longitudinal ball hinge are also visible on those side walls of the insulating panel situated at the top and bottom in the figure.
  • the insulating panel is preferably embodied such that, in placed situation, a male (protruding) part of the ball hinge is provided at the top and a female (recessed) part at the bottom.
  • a male (protruding) part of the ball hinge is provided at the top and a female (recessed) part at the bottom.
  • the male part and the female part are preferably rounded so that a pivotable hinge is formed and so that mutually connecting insulating panels can be placed at a small mutual angle without the horizontal join becoming visibly larger. Small variations in verticality of the wall to be covered can thus be compensated.
  • the combination of a male part provided on the upper side of the insulating panel and a female part provided on the underside of the insulating panel has the additional advantage that, in placed situation, seeping of rainwater into the horizontal joins is prevented. It is useful in this embodiment to adapt the course of groove 105 for receiving a sealing strip to the presence of the ball hinge, for instance by having the groove slope from the onset of the male part at the top of the insulating panel.
  • the groove preferably runs obliquely toward a point closer to the free side at the bottom of the insulating panel. In this way inseeping rainwater is guided away from the ball hinge by the sealing strip of the wall.
  • a simpler overlapping hinge is also possible, wherein the edge of the insulating panel situated at the top in the placed situation has a recess on the free side, which recess couples to a modified recess on the attaching side in the bottom edge of a higher placed insulating panel.
  • FIG. 6 is a schematic top view serving to illustrate the use of the insulating panel according to the invention as formwork for a cast structure 603 , preferably a concrete structure.
  • the insulating panels are placed in continuous planes on either side of the structure to be erected, wherein a connecting means 601 is provided in recesses 107 in order to consolidate the whole.
  • Recesses 106 are filled with a suitable sealing means in order to prevent penetration of concrete liquid into the joins, shown here as a concrete formwork triangular prism 602 , preferably of PVC.
  • the joins between the insulating panels and between the insulating panels and wedge 106 are shown enlarged in Figure 6 for the sake of clarity.
  • the space between the thus formed formwork surfaces is filled up with the casting mortar, preferably concrete, which when cured will form structure 603.
  • Figure 7 is a schematic top view serving to illustrate the use of the insulating panel according to the invention as insulating and finishing layer on an existing wall 701 .
  • the insulating panels are adhered with their attaching side 103 to wall 701 at diverse locations by means of an adhesive 702 .
  • Adhesive 702 preferably ensures an immediate stabilization of the insulating panel during the placing operations.
  • the recesses provided at the position of the vertical side walls are filled with another adhesive 703, preferably a foam-like adhesive. Sealing strips 704 are arranged in the recesses provided for this purpose so that a watertight whole is formed with the free sides 104 of the placed insulating panels.
