Definitions

  • the present invention in the first place concerns a method for applying an insulation layer to a wall.
  • the invention relates to such a method which does not require any drilling.
  • the wall is preferably made of stones, whereby these stones can take a variety of forms and may be, for example bricks, but also concrete stones or blocks made of cellular concrete and the like.
  • the wall is formed of cast concrete.
  • a method according to the invention can moreover be applied even to walls that are not made of stone materials .
  • the insulation layer may be an insulation sheet, insulation panel or insulation mat or the like, consisting of a thermally insulating and/or sound-insulating material .
  • the method according to the invention is typically intended for the application of an insulation layer to an inner leaf of a cavity wall.
  • a variety of methods are known for applying an insulation layer to a stone wall, which have a number of disadvantages .
  • the insulation layer is fixed to the stone wall by applying an adhesive, whereby an adhesive material is provided on the wall between the wall and the insulation layer.
  • a first disadvantage of this method consists in that during the application of the adhesive a correct dosage is to be applied, on the one hand sufficient adhesive in order to obtain the necessary bearing capacity and adhesive strength of the insulation layer against the wall, but not too much adhesive on the other hand so that, when the insulation layer is pressed on, no excess adhesive will be ejected.
  • Another disadvantage of this method for applying an insulation layer is that, before the adhesive has cured, the insulation layer can often still easily move with respect to the wall, which makes its installation difficult sometimes.
  • the insulation layer is fixed to a wall by means of a plug or the like.
  • holes need to be drilled in the wall for applying the plug, which is a labour-intensive and time- consuming job requiring many tools, whereby electricity should be readily available, and so on.
  • Securing the plug in the drill hole generally requires additional operations as well, such as screwing down a screw or patting a pin and the like, which again slows down the placing of insulation sheets.
  • the currently constructed walls are often built of fast- building blocks having large cavities, which is often not beneficial to the efficiency of the plug operation.
  • the present invention aims to remedy one or several of the above-mentioned disadvantages of the known methods for applying an insulation layer to a wall and possibly also aims to provide a solution to other disadvantages thereof .
  • the invention aims a method without any drilling .
  • the invention concerns a method for applying an insulation layer to a wall without any drilling, which method consists of the following steps:
  • a major advantage of such a method according to the invention is that an insulation layer can be attached to a wall without any drilling, which is of course much faster than a method requiring some drilling, and whereby a method according to the invention does not have the disadvantages of gluing.
  • Another advantage of such a method according to the invention is that fixing the insulation layer to a wall is very easy, as the operations for making the female coupling sections of the wall cooperate with the male coupling elements on insulation anchors are very limited.
  • Another advantage of a method according to the invention is that the anchoring of an insulation layer to a wall is also very readily reversible in order to loosen the insulation layer again, making it easy to re-use or recycle the insulation material .
  • the wall is composed by stacking stones, whereby during the manufacture of the stones, a pre-shaped female coupling section is provided in the stones so as to form one or several female coupling sections of the wall.
  • Such a preferred method according to the invention is very interesting as the female coupling sections can be provided in the stones while they are being manufactured, for example in a production hall, which can be done very efficiently and in an automated and controlled manner under ideal circumstances .
  • said one or several female coupling sections of the wall consist of one or several grooves whose edges are provided with inwardly directed hooks and not with holes, as is the case in the known methods requiring some drilling.
  • Such female coupling sections in the wall in the shape of one or several grooves offer the advantage that the insulation layer can be positioned even more easily by shifting the male coupling elements of the insulation anchors concerned in the corresponding grooves in the wall .
  • female coupling sections are obtained which allow for a good anchoring of a male coupling element of an insulation anchor, in particular by providing the male coupling section with a part that is complementary to said groove and which can hook behind the inwardly directed hooks of the groove.
  • the insulation anchors are provided in the insulation layer before the insulation layer is placed against the wall concerned.
  • a major advantage of this preferred method according to the invention consists in that the insulation anchors can be provided in the insulation layer beforehand, for example in an automated manner in the hall where the insulation layers are produced, whereby the insulation anchors are part of the insulation layer as if it were at the time of delivery.
  • the invention also concerns an insulation anchor designed to be applied through a hole in an insulation layer so as to fix the insulation layer to a wall without any drilling.
  • Such an insulation anchor according to the invention comprises at least the following elements:
  • figure 1 shows a stone in perspective which, according to a method of the invention, is provided with female coupling parts in the shape of a pair of grooves ;
  • figure 2 shows an intermediate position in perspective of an insulation sheet while it is being fixed according to a method of the invention to a stone wall formed of stones as represented in figure 1;
  • figures 3 and 4 show a view in perspective of the front side and the back side of the stone wall from figure 2 respectively, after the insulation layer has been applied;
  • FIGS. 5 and 6 are representations in perspective of cross-sections through a part of a stone from the wall in figures 3 and 4 and through a part of the insulation layer, as well as through a first embodiment of an insulation anchor according to the invention used for fixing the insulation layer, in a position in which no wall tie has been applied yet and a position in which said wall tie has been applied respectively;
  • figure 7 shows a cross-section in perspective, analogous to that in figure 5, but in which a second embodiment of an insulation anchor according to the invention was used for applying the insulation layer;
  • figures 8 and 9 show cross-sections according to arrows F8 and F9 of the insulation anchor and the insulation layer, represented in figures 5 and 6 respectively; and,
  • figure 10 shows a cross-section according to arrow F10 of the insulation anchor and the insulation layer represented in figure 7.
  • FIG. 1 By means of figures 1 to 4 is illustrated a method according to the invention for fixing an insulation layer 1 to a wall 3 made of stones 2 without any drilling.
  • the wall 3 is provided with one or several female coupling sections 4.
  • these coupling sections 4 in this case consist of vertically directed, parallel grooves 4 extending at regular distances D from one another over the wall 3, in particular as of a lower edge 5 of the wall 3 up to an upper edge 6 of the wall 3.
  • These female pre-shaped coupling sections 7 of the stones 2 are formed - in this case - of a pair of grooves 7 extending vertically from one another at a distance D over one of the side flanks 8 of the stone 2, more particularly from the bottom surface 9 of the stone 2 to its upper surface 10.
  • the wall 3 is then formed by stacking the stones 2 in a half-brick bond, whereby the pre-shaped grooves 7 in the stones 2 are aligned so as to form continuous grooves 4 in the wall 3.
  • the embodiment of a stone 2 as shown in figure 1 is centrally provided with three vertical passages 11 and 12, whereby the two outer vertical passages 12 have a square cross-section.
  • plastic inserts 13 and 14 are intended to make it easy to couple the stones 2 to one another by a cooperation of the female inserts 13 on the bottom surface 9 of a first stone 2 and the male inserts 14 on the upper surface 10 of an adjacent stone 2, as if it were according to the known LEGO block principle, and without having to apply any mortar or the like to this end.
  • the stones 2 can be stacked seamlessly and they can be coupled so as to form the wall 3.
  • the grooves 4 forming female coupling sections 4 of the wall 3 have a special shape according to the invention which is particularly suitable for fixing an insulation sheet 1 to the wall 3.
  • these grooves 4 in the wall 3 or the grooves 7 in a stone 2 are provided on both longitudinal edges 15 with inwardly directed hooks 16, or in other words directed towards each other, whereby a groove 4 or 7 thus has a larger width B at its bottom 17, from which a narrowed part 18 with a narrower width B' extends up to the side flank 19 of the wall 3 or the side flank 8 of the stone 2.
  • the grooves 4 and 7 have a T-shaped cross-section.
  • the insulation layer 1 is provided with holes 20. Furthermore, the aim is to apply an insulation anchor 21 according to the invention through said holes 20 in the insulation layer 1. Said insulation anchor 21 has an elongated, central body 22 with a cross-section corresponding to the cross-section of the hole 20 in the insulation layer 1.
  • a supporting flange 24 designed to make it possible for the insulation anchor 21 to rest against a first side 25 of the insulation layer 1, as is represented in more detail in figures 5 to 10.
  • a male coupling element 27 which, after the insulation anchor 21 has been applied through the hole 20 concerned in the insulation layer 1, protrudes from the insulation layer 1 on the other side 28 of the insulation layer 1.
  • An aforesaid male coupling element 27 can work in conjunction with a female coupling section 4 of the wall 3, i.e. in this case with a longitudinal groove 4 having a T-shaped cross-section in the wall 3.
  • Such a male coupling element 27 is in this case mainly formed of a protruding part 29 of the central body 22 on the one hand which, after the insulation anchor 21 has been applied through a hole 20 in the insulation layer 1, protrudes from the insulation layer 14 on the other side 28 of the insulation layer 1, and of a coupling flange 30 on the other hand provided on the far end 26 of the aforesaid part 29 and which can work in conjunction with a groove 4 in the wall 3 with the inwardly directed hooks 16.
  • the protruding part 29 has a diameter which corresponds to or is somewhat smaller than the diameter B' of the narrowed part 18 of a groove 4 in the wall 3.
  • the coupling flange 30 has a diameter which is sufficiently large in relation to the narrowed part 18 of a groove 4 in order to ensure a good anchoring on the one hand, but which is also sufficiently small in relation to the widened part of the groove 4 having a width B at its bottom 17 in order to obtain sufficient play of the coupling flange 30 in this widened part on the other hand.
  • an insulation anchor 21 according to the invention comprises two separate parts, in particular a supporting part 31 containing the supporting flange 29 and a coupling part 32 containing the male coupling element 27.
  • the supporting part 31 and the coupling part 32 are provided with coupling means 33 with which they can be coupled together by providing the parts 31 and 32 on either side, more specifically on the side 25 of the insulation layer 1 and the side 28 of the insulation layer 1 respectively, in a hole 20 concerned and by moving them towards one another.
  • the coupling part 32 and the supporting part 31 are provided with an internal thread 34, an external thread 35 respectively, which can cooperate by rotating the coupling part 32 and the supporting part 31 with respect to each other.
  • a hexagonal socket 36 is provided in the supporting flange 24 in the given embodiment, in which a hexagonal socket wrench can be fit.
  • the hole 20 hereby also has a stepped design in order to offset the difference in diameter between the supporting part 31 and the coupling part 32. Naturally, the same can be obtained by providing the supporting part 31 with an internal thread 34 and the coupling part 32 with an external thread 35.
  • the coupling part 32 and the supporting part 31 can be provided with one or several internal ridges 37, external ridges 38 respectively (or vice versa) , which can cooperate thanks to a rectilinear movement towards each other of the coupling part 32 and the supporting part 31.
  • Such an embodiment of an insulation anchor 21 according to the invention is represented in figures 7 and 10, whereby the coupling part 32 is in this case provided with only one internal ridge 37, formed of an inwardly directed edge 37 on the far end of the coupling part 32, which can cooperate with the external ridges 38 provided on the supporting part 31.
  • the coupling part 32 and stone part 13 can be moved towards one another simply by giving the supporting part 31 a stroke.
  • the ridges 37 and 38 should be made sufficiently elastic.
  • Another preferred characteristic of an insulation anchor 21 according to the invention consists in providing the insulation anchor 21 with tightening means 39 to set the distance between the supporting flange 24 and a part of the male coupling element 27 with which a female coupling section 4 of a wall 3 can be grabbed.
  • Such a section is in this case formed for example by the coupling flange 30.
  • the tightening means 39 are at least partly formed by the coupling means 33, as is the case for example in figures 5, 6, 8 and 9.
  • the tightening means 39 may be at least partly formed by the male coupling element 27.
  • the male coupling element 27 can be provided for example with a screw shape.
  • An insulation anchor 21 according to the invention is preferably made hollow according to the invention, such that a wall tie 41 can be inserted in the provided cavity 40, as is illustrated in more detail in figure 9.
  • the coupling flange 30, on its side which is to be directed to the bottom 17 of a groove 4 in the wall 3, may be provided with one or several spacers 42 so as to make it easy for the coupling flange to be positioned in the groove 4 concerned .
  • such spacers 42 are formed by several standing projections 42 extending out of the plane of the coupling flange.
  • an insulation sheet 1 can be fixed to the wall 3 by making one of the aforesaid male coupling elements 27 of the insulation anchors 21 provided in the insulation layer 1 cooperate with corresponding female coupling sections 4 of the wall 3.
  • the insulation anchors 21 are provided in the insulation layer 1 before the insulation layer 1 is put against the wall 3 concerned.
  • the male coupling elements 27 protruding from the insulation layer 1 are provided on the free upper edge 6 of the wall 3 in a corresponding groove 4 of the wall 3.
  • Figure 2 represents an intermediate position of the insulation sheet 1 during this sliding movement, whereas figures 3 and 4 represent the final position.
  • the insulation layer 1 can be pressed against the wall 3, whereby use is preferably made of the tightening means 39 according to the invention, which need to be activated accordingly depending on the type.
