Definitions

  • roof covering material which is attached to a substrate by means of heating, for instance by burning.
  • Various other roof covering materials are known for the purpose of obviating this drawback.
  • EP-A-1 953 306 thus describes a substantially flat roof comprising a substrate having a layer of fastening material of a first type extending at least over a part of the surface of the substrate and at least a layer of roof covering elements which are arranged substantially adjacently of each other and which are each provided with a layer of flexible watertight material, such as bituminous material, and a layer of fastening material of a second type which extends at least partially over the surface of the roof covering element and which is engaged by fastening material of the first type attached to the roof.
  • the substrate is provided here with pieces of hook material fixed to the substrate by means of screws or nails, and the roof covering elements are provided with a layer of loop material extending over the greater part of the surface.
  • the hook material engages the loop material.
  • roof covering elements are known in the form of 'Rhepanol FT'.
  • Such roof covering elements for a substantially flat roof comprise a layer of flexible watertight plastic and the lower side of which substantially over its surface provided of pieces of loop material with loops and which is adapted to engage fastening material provided on the roof.
  • JP 4343959 A discloses a roof covering element according to the preamble of claim 1.
  • the rate of fastening between the roof covering element and the carrier is dependent on the location and the number of pieces fastening material per surface area of the carrier.
  • the object of the invention is to provide such a roof covering element wherein the rate of fastening is more predetermined and is less prone to variations.
  • fastening material is arranged in the form of separate pieces distributed over the surface of the roof covering element, along with further features according to appended claim 1.
  • the position of the pieces of hook material is determined during the production of the roof covering elements. It is assumed that on a sufficient large section of the roof fastening material is present to ensure that each of the pieces of hook material contacts a corresponding piece of fastening material. When about 10% of the surface area of the roof covering elements is covered by hook material good results have appeared, although it will be clear that this percentage is also dependent on the expected wind load and of other variables, so that it is possible that a greater section, for instance 15% of the roof covering element is covered by hook material. Further it is attractive when the hook material has a colour different from the colour of the roof covering element.
  • the hook material on the roof covering element is adapted to engage the loop material on the carrier. It is not excluded that the hook material is provided on the carrier which is engaged by the hook material on the roof covering element.
  • Another advantage of this feature is the absence of removability of the fastening material at the edges of the roof covering element to allow easy overlapping positioning thereof and to join it to the underlying structure by melting without interference of disturbing parts. Another advantage resides in the easy processability saving working time. A last advantage is the separation of the diverse materials after demolishing.
  • At least one fastening strip comprises at least a first and a second part which are each connected to the layer of flexible material, and which are mutually connected by a weakened joint.
  • the layer of hook material is in the shape of strips on the layer of flexible material. This simplifies mechanical positioning of the pieces of hook material.
  • Reference is made here to WO-A-98/36139 from which are known shingles provided with one or two strips of hook material. This relates to shingles, i.e. roof covering elements only suitable for covering sloping roofs. Such shingles can thus be placed overlapping without the danger of water entry. Because the danger of water entry is considerably greater in the case of horizontal roofs, shingles are not suitable for application on horizontal roofs.
  • the layer of flexible material may be adapted to be placed in abutting manner. It is hereby possible to cover the whole surface of the roof without overlap. It is noted here that provisions are necessary for the purpose of providing sealing at the position of the joins between the roof covering elements. It is however also possible that the layer of flexible material is adapted to be placed in overlapping manner.
  • a further embodiment provides the measure that the roof covering element has an elongate form and that the fastening strips are arranged in the longitudinal direction of the roof covering element.
  • the use of such elongate roof covering elements provides the option that they can be handled in the form of rolls and rolled out onto the roof. Such rolls are usually made by means of extrusion or by other methods where it is easy to arrange structures extending in the longitudinal direction such as fastening strips.
  • An alternative embodiment provides a roof covering element which has an elongate form and wherein the fastening strips are arranged in the transverse direction of the roof covering element.
  • a third part has been located between the first and the second part which is releasably connected to the layer of flexible material or which is not connected to the layer of flexible material.
  • the releasable connection allows to release the relevant part of the fastening strip from the layer of removable material and to remove it therefrom. This is important when the roof covering element is cut off and the released part of the flexible element is located at the edge, allowing a part of the flexible material to overlap an adjacent roof covering element. A comparable effect is obtained when the third part is not connected to the flexible part.
  • the releasability can be obtained in that thin uncoupling strips connected neither to the flexible material nor to the third parts of the fastening strips extend between the third parts of the fastening strips and the flexible material.
  • This embodiment offers the option during extrusion of the roof covering element in the longitudinal direction of adding the thin uncoupling strips between the flexible material and the fastening strips so that in this way fastening is prevented at this position. It is however also possible to provide the fastening strips of weakened joints located at regular intervals to ease the removal of the pieces of fastening strip, for instance when shortening the roof covering element.
  • the fastening strips locally increase the thickness of the roof covering element.
  • the upper surface thus becomes uneven and this may be undesirable for aesthetic and/or technical reasons.
  • another embodiment proposes that the fastening strips are recessed over at least a part of their thickness into the layer of flexible material.
  • the fastening strips can be arranged in numerous patterns on the flexible part of the roof covering elements. As stated above, the strips can be placed in the longitudinal direction or in the transverse direction. It is likewise possible to arrange the strips crosswise, although this will result in local thickening in the roof covering element. When the strips are arranged mutually parallel, it is recommended that the fastening strips are arranged at equal mutual distances. This is possible with fastening strips extending in both longitudinal direction and in transverse direction.
  • the fastening strips being arranged at mutually differing distances, for instance for specific applications, is not however precluded.
  • the ratio of the width of the fastening strips and the mutual interspacing of fastening strips is smaller than the average distance between the fastening strips.
  • the layer of flexible watertight material comprises at least two layers, of which the lower layer is adapted to form a connection with an underlying structure in an overlap and the upper layer is adapted to withstand sun radiation.
  • the lower layer is adapted to form a connection with an underlying structure in an overlap
  • the upper layer is adapted to withstand sun radiation.
  • the lower layer comprises SBS (styrene butadiene styrene), and the upper layer comprises polyolefins such as APAO( amorph polyalfaolefine), TPO (thermoplastic polyolefine), POCB, (polyolefine copolymeric binder) or APP (atactic polypropylene).
  • the layer of flexible watertight material comprises from one of those materials as a whole.
  • the fastening layer When the method of producing the roof covering elements does not allow integration of the fastening layer, it is attractive for the fastening layer to be arranged via a membrane-like carrier on the bituminous material. This can then be arranged later on the roof covering element.
  • the above elucidated roof covering elements are adapted for fastening to a substrate of a roof.
  • the present invention discloses a substrate as part of a substantially horizontally extending roof, which substrate is provided with a layer of fastening material which extends over substantially the whole part of the surface of the substrate.
  • Such a substrate is therefore suitable for covering with roof covering elements which are provided with a layer of fastening material extending over a part of the surface of the roof covering element.
  • the fastening material which will often be in the form of a loop material, can also be connected to a membrane like carrier, and which can be joined to the substrate. Then the membrane like carrier can be adhered to the substrate by glue, an adhesive later or in a mechanical way. Also then the combination of membrane like carrier and fastening material can be perforated.
  • a rigid structure may be used.
  • a carrier comprising a rigid roof plate, onto which a layer of fastening material is applied extending substantially over the whole surface of the plate.
  • the rigid roof plate forms a part of the roof, such as a sandwich panel onto which the roof covering element is located.
  • the rigid panel is formed by a piece of insulation material onto which the roof covering elements are located. Said insulating panel can be connected to the substrate of the roof by a screw connection or another kind of connection.
  • a preferred embodiment of the present invention therefore provides a carrier to be covered by a roof covering element of the kind referred to above wherein the carrier comprises a thermal insulating roof segment adapted to located on a carrier of a roof and to be connected to the roof carrier and on the upper side whereof a layer of loop material is provided.
  • the thermal insulating roof segment is preferably formed by PUP/PIR, EPS or a mineral wool, although other materials are not excluded.
  • the thermal insulating roof segment comprises a fastening layer on its lower surface adapted to engage a fastening layer on the roof substrate.
  • the roof segment can be provided on both sides with hook material or with loop material when the relevant fastening layers are provided with loops or hooks, although it is however recommended that the roof segment is provided with hook material on its underside and that the roof segment is provided with loop material on its upper side.
  • a metal foil has been positioned between the fastening layer at the lower side and the insulation material. This foil also functions as a damp proof layer.
  • hook material it is also attractive for the hook material to be arranged in the form of pieces distributed over the lower surface of the roof segment, leading to a saving of hook material.
  • the above embodiments provide a roof covered by roof cover elements of the kind referred to above, in which the roof comprises a roof substrate comprising a layer of fastening material extending over substantially the whole surface of the roof and being engaged by the layer of hook material of the roof covering elements.
  • FIG. 1 shows a number of roof covering elements, each designated as a whole with 1.
  • Each roof covering element comprises a layer 2 of bituminous material, to the underside of which are fixed a number of fastening strips 3 of hook material 3 provided with hooks.
  • This hook material is also known under the brand name Velcro.
  • Roof covering elements 1 are each placed on a substrate 4 which can be arranged on a wooden roof floor but which also can be formed by a metal roof floor or even by a concrete roof floor.
  • a layer 5 of material Arranged on this roof layer 4 is a layer 5 of material provided with loops which is adapted to be engaged by the hook material. Loop material 5 is preferably formed by a non-woven material screwed onto substrate 4. Other fixing methods are not precluded.
  • the fastening strips 3 extending over only a part of the lower surface of each of the roof covering elements 1 are situated at the edges of roof covering elements 1 in order to ensure that roof covering elements 1 are properly fixed at their edges.
  • Roof covering elements 1 are placed connecting to each other. This means that joins are present between adjacent roof covering elements 1.
  • a band 6 is arranged over these joins.
  • This band 6 can be manufactured from special material which can be connected, for instance by glueing or by heating and the thus resulting melt, to both underlying roof covering elements 1. It is however also possible to make use of ribbons of the roof covering elements 1. Owing to their preferably bituminous character these can likewise be fused or adhered to the underlying roof covering elements 1.
  • FIG. 2 shows a bottom view of a roof covering element 1.
  • Roof covering element 1 is rectangular and in the present example also elongate. It will be apparent that the manufacture of elongate roof covering elements is attractive in respect of production by means of extrusion and similar processes and the convenience of transport of rolls of such material. The length of the roof covering elements is therefore variable.
  • the fastening strips 3 with hook material are arranged in the longitudinal direction. This direction also facilitates production because the fastening strips can be added during the extrusion process. Because the material from which layer 2 is manufactured is then in the liquid state, a connection occurs between this material and the fastening strip when cooling takes place.
  • This embodiment also shows that fastening strips are arranged on both long sides of the roof covering elements in order to arrive at a good fixing of the edge of the roof covering elements. It is in principle not precluded at a single edge to place the fastening strip at a distance from the edge so as to leave clear a part adjoining this edge which can then for instance be used to form an overlap with the connecting roof covering element.
  • Figure 3 shows a bottom view of an embodiment wherein the fastening strips extend in the transverse direction.
  • this structure may be attractive when short fitting pieces are used; it is then possible to shorten a piece of roof covering material to a desired length and still have the cut of the shortening located in the vicinity of a fastening strip.
  • This embodiment further shows that the fastening strips are placed with the same mutual interspacing. This is the most attractive from the viewpoint of distribution of forces, although there may be other reasons for arranging the fastening strips at different distances.
  • Figure 4 shows an embodiment largely corresponding to the embodiment shown in figure 3 , but wherein two bands 7 extend between each of the fastening strips 3 and the actual roof covering elements 2.
  • These bands 7, which are manufactured from a thin, preferably plastic material, have the result that pieces of fastening material 3 are locally not connected to roof covering element 2. Because the fastening strips 3 are however connected elsewhere to the roof covering elements, the fastening strips can still fulfil their function.
  • the separate parts make it possible however to remove the fastening strips locally, for instance when the roof covering elements are cut into pieces. It is otherwise also possible to make use of pieces of band extending under only a single fastening strip.
  • fastening strips 3 which are partially recessed into the material of layer 2 of roof covering element 1.
  • Fastening strips 3 hereby no longer protrude relative to the underside of layer 2, or hardly so, and a very smooth surface is hereby realized, which may be highly desirable for aesthetic and/or technical reasons. It is noted that fastening strips 3 are received for a great part of their thickness in the underlying layer of loop material 5, even when fastening strips 3 are not recessed.
  • FIG. 5 Another measure shown in figure 5 is the presence of a band 6 which is already adhered to roof covering element 1 and which serves to cover the join between adjacent roof covering elements. Logistics are simplified by already adhering this band 6 to one side of roof covering elements 1. Use can be made for adhesion purposes of heating or glueing, although band 6 can also be co-extruded in the extrusion process.
  • FIG. 6 shows a roof construction, wherein not only roof covering elements 2 but also roof segments 8 therebetween are placed on the substrate of the roof which serve to improve the thermal insulation of the whole roof construction.
  • Roof segments 8 are each manufactured for instance from expanded polystyrene, PUR or PIR.
  • the roof segments are each provided with a number of fastening strips 3 which are not necessarily though preferably attached to the roof covering elements. A saving in fastening material is hereby also achieved.
  • the upper side of each of the roof segments 8 is also provided with a layer of loop material 5. With the thus obtained configuration it is possible to arrange an insulating layer between substrate 4 and the roof covering elements.
  • FIG. 7 shows a membrane 20 formed by a plastic sheet 21.
  • Sheet 21 is reinforced with for instance reinforcing lines 22 which are manufactured from fibres and arranged in a rectangular pattern.
  • Pieces of hook material 23 are arranged on the membrane in a rectangular pattern.
  • the reinforcing lines are arranged between the pieces of hook material although it is also possible to arrange the lines elsewhere.
  • the membrane has sufficiently little stretch so that, when the membrane is attached to the substrate, for instance with screws or nails, possibly strengthened with a rosette or plate, the pieces of hook material remain close to the substrate so that the wind cannot enter between the membrane and the substrate and, when the roof covering elements are fixed directly onto the membrane, wind cannot enter between the membrane and the roof covering element.
  • rigid roof segments in the form of insulation to be placed on the membrane.
  • the membrane be attached by means of a glueing or in self-adhesive manner to the substrate.
  • FIG 8 shows a cross-section of a roof 30 comprising a for instance wooden substrate 31 to which roof segments 32 are fixed by means of screws 33.
  • the insulating material is formed for instance by mineral wool, expanded polystyrene, PUR or PIR.
  • the roof segments 32 are provided with a layer of loop material 33 extending over the whole area of roof segments 32.
  • roof covering elements 35 are provided on their underside with pieces of hook material 36 which is in engagement with loop material 35 of roof segments 32.
  • the roof segments can also be formed by structural roof parts, such as by sandwich panels. These sandwich panels are then fixed directly, without interposing a substrate, onto the beam layer of the roof.
  • FIG 9 shows a roof at 40 comprising a substrate 41 on which two layers of insulating material are placed in the form of two offset layers of roof segments 42, 43 on which roof covering elements 44 are arranged.
  • a layer of loop material 45 is arranged in the usual manner on the substrate.
  • the lower layer of roof segments is provided on the underside with pieces of hook material 46 and on the upper side with a layer of loop material 47.
  • the upper layer of roof segments is provided on underside and upper side with layers of hook material 48, 49, while roof covering elements 44 are provided on their underside with a layer of loop material 50.
  • the associated layers of fastening material are brought into engagement with each other.
  • the upper fastening layer i.e. that between the upper layer of roof segments 43 and the roof covering elements 44, is here as it were 'switched', which may be attractive in many cases for reasons of availability of material. It will be apparent that the other fastening layers can also be 'switched'.
  • FIG 10 shows a cross-section of a substrate 4 of a roof on which a layer 5 of loop material is arranged.
  • roof covering elements 1 which, as in figure 1 , are formed by a layer of bituminous material 2 which is provided on its underside with pieces of hook material 3 which engages with loop material 5.
  • This embodiment differs from the embodiment of figure 1 in the fact that the pieces of roof covering material 2 overlap each other. In order to obtain a liquid-tight connection between roof covering elements 2, they are connected to each other on the overlapping part by a melted join 10.
  • FIG 11 shows a cross sectional view of a thermal insulating roof segment 50, comprising an insulating body 51 made from PUR/PIR and which comprises layers 52, 53 from metal foil at its upper face, respectively lower face, which layers function as water tight layers.
