Definitions

  • the present invention relates to a method for cladding a wall with stone strips.
  • Stone strips are herein understood to mean strips of all types of materials such as, but not restricted to, concrete, epoxy, natural stone, brickstone or cement.
  • the wall is first provided with a layer of plaster in which the stone strips are pressed in a condition in which the layer of plaster is still wet. After curing of the layer of plaster the stone strips are secured on the wall and the joints between the stone strips can be pointed.
  • the traditional gluing of stone strips has several disadvantages, i.e. the stone strips may still sag in the wet layer of plaster under their own weight, such that the joints between the stone strips located above each other are not straight, leaving a messy impression.
  • said method is relatively labour-intensive for levelling the stone strips in horizontal rows and requires an execution by experienced professionals.
  • Another already known technique to simplify the aforementioned works consists of applying pre-formed or milled insulation panels which are part of an ETICS (external thermal insulation composite system) insulation system. Said insulation panels are attached with one side against the wall and on the opposite side are provided with parallel ribs which are milled or pressed into the insulating material of the insulation panels, whereby said ribs are intended for aligning the stone strips glued between them.
  • ETICS internal thermal insulation composite system
  • a disadvantage of said known method for cladding the wall with stone strips is that the insulation panels are relatively expensive because they must be provided with extra ribs and the fact that, in the case of ribs milled from the insulating material, a lot of material is lost.
  • the purpose of the present invention is to provide a solution to the aforementioned and other disadvantages.
  • the present invention which is defined by the appended claims, relates to a method for cladding a wall with stone strips, whereby the method contains the following steps:
  • the ribs formed in this way by curing of the layer of plaster, are sufficiently firm to offer sufficient support when mounting the stone strips to prevent the stone strips from sagging during mounting.
  • the ribs are located at fixed distances from each other and in each other's extension, continuous compartments are delimited between the ribs between which the stone strips are automatically aligned to each other, such that the method is easy to apply compared to the known method and such that the number of necessary working hours to realise the wall is reduced and the need for skilled professional decreases.
  • the ribs function as support point for the stone strips and preferably have a height that is less than the thickness of the stone strips. Impression moulds are used for this, the depth of the grooves of which is less than the thickness of the stone strips.
  • the ribs are located at a distance from each other which is slightly greater than the width of the base of the stone strips to be applied, all this such that a gap remains between the stone strips and the ribs which when pressing the stone strips into the adhesive mortar between the ribs allows the superfluous adhesive mortar to be pushed out through said gap.
  • the stone strips can be pressed to a desired depth between the stone strips, for example to obtain one plane or to achieve a certain desired relief.
  • the invention is applicable both for walls with and without a joint or with a minimal joint between the stone strips.
  • stone strips can be used which at their base are provided with one or more recesses with which the stone strips fit over the ribs breadthways, in such a way that the stone strips connect closely to each other.
  • this can be realised for example by stone strips which in their base surface, in other words the surface with which they are pressed into the adhesive mortar, are provided with such recess along two opposite edges.
  • the invention also relates to a kit for use in the method, whereby the kit contains at least one stone strip and contains an impression mould for forming parallel ribs in a layer of plaster intended for attaching the stone strips against, said impression mould being provided with parallel grooves at least on one side at a distance from each other which is slightly greater than the width of the base of the stone strips to be applied.
  • kit offers at least the same advantages as the method for cladding a wall with stone strips.
  • the impression mould is preferably rectangular and in a preferred embodiment is made of a light material such as foam, for example but not exclusively of polyethylene, foam-rubber or plastic foam.
  • the impression moulds can also be made from other materials to which the dried layer of plaster does not stick.
  • the impression mould 1 shown in figure 1 is made from a block of foam with two opposite parallel edges 2 and 3 which are connected to each other by two opposite sides, respectively one side 4 which is flat and the other side 5 which is provided with grooves 6 that run parallel with the aforementioned edges 2 and 3.
  • the grooves 6 are located at a fixed distance A from each other, whereby in the case the outer grooves are located at a distance B', respectively B", from the adjoining edge, respectively 2 and 3, the sum of said distances B' and B" is equal to said fixed distance A, such that when two impression moulds 1 are positioned with their edges 2, 3 against each other, the outer grooves of said adjacent impression moulds 1 are located at a distance A from each other.
  • Figure 2 shows a cross-section of a wall 7 which is intended to be cladded with stone strips 8, whereby the wall 7 is already provided with an insulation panel 9 which in this case is attached against the wall 7 by means of anchors 10 and/or adhesive cement.
  • the side 11 of the insulation panel 9 to be cladded is flat, such that against said flat side 11 a reinforcement mesh 12 can be applied as shown in figure 2 , whereby for the execution of the method according to the invention a layer of plaster 13 in wet condition is applied over the reinforcement mesh 12.
  • a first layer of plaster can, for example, be applied against the wall into which the reinforcement mesh 12 can be pressed, after which possibly a second layer of plaster 13 can be applied over the reinforcement mesh 12.
  • the reinforcement mesh 12 is glued.
  • the layer of plaster 13 is covered with impression moulds 1 which with their grooved side 5 are pressed into the wet layer of plaster 13, in this case with the grooves 6 oriented horizontally and such that the plaster penetrates in the grooves 6.
  • impression moulds 1 are applied in horizontal rows 14 with their edges 15 and 16 laterally against each other, such that the grooves 6 extend in each other's extension.
  • the impression moulds 1 are stacked row by row with their edges 2 and 3 against each other, whereby preferably the rows 14 are staggered in the direction parallel with the grooves 6 relative to each other over a length that is less than the length C of the impression moulds 1, such that the rows, when mounted, are staggered relative to each other as illustrated in figure 3 .
  • the impression moulds 1 are removed after the layer of plaster 13 has cured sufficiently, for example after one to two days, depending on the curing time of the plaster used.
  • a cured layer of plaster 13 remains after removal of the impression moulds 1, which is provided with ribs 17.
  • a layer of adhesive mortar 18 is applied against the layer of plaster 13, at least between the ribs 17, after which, as shown in figure 7 , stone strips 8, which may or may not be provided with a layer of adhesive mortar 18 at the base 19 for a better adhesion of the stone strip 8, are pressed into the wet adhesive mortar 18.
  • bar-shaped stone strips 8 with a rectangular base 19 are used with which they are pressed into the adhesive mortar 18.
  • the impression moulds 1 are chosen such that the distance D between two parallel adjoining ribs 17 is greater than the width E of the wall-facing base 19 of the stone strip 21 to be applied, such that when the stone strips 8 are pressed into the adhesive mortar 18 between the ribs 17, the superfluous adhesive mortar 18 can be pushed out through the gap 20 between the ribs 17 and the stone strips 8 into the joint 21 between adjacent stone strips 8.
  • the joints 21 can be pointed with grout 22 as shown in figure 8 to finish the wall 7 with stone strips 8.
  • Figure 9 shows a possible variant 1 of an impression mould 1 according to the invention which differs from the impression mould 1 of figure 1 in that said variant is provided along two opposite edges 15, 16 with a tongue 23 and groove 24 with which adjoining impression moulds 1 in a same row 14 fit in each other's extension.
  • Figure 10 shows an example of an application of the method according to the invention, but for a finished wall 7 with stone strips 8 without or with minimal joints 21.
  • the base 19 is provided along two opposite edges with a recess 25 with which the stone strips 8 fit over the ribs 17 as shown in figure 10 , and whereby, in other words, the stone strips 8 are executed 26 wider on the visible side with a width F which is chosen such that when the stone strips 8 are supported with their base 19 against or on a rib 17, only a small joint 21 is present between consecutive rows of stone strips 8 which does not necessarily have to be pointed.
  • the stone strips 8 can also be provided with one recess in the form of a groove on one single edge or in the form of a groove between two opposite edges of the base (19) which fits over a rib 17 and extends parallel to said edges.
  • edges 2, 3, 15 and 16 of the impression moulds 1 are provided with protrusions and recesses with which the impression moulds 1 fit against each other with their edges 2, 3, 15 and 16.
  • the described method for cladding a wall 7 with stone strips 8 can be executed on both hard foundations such as for example brick work, concrete surfaces or hard composite plates as well as on soft foundations, including insulating material.
  • the present invention also relates to a kit for use in the method.
  • Such kit contains at least one stone strip 8 and an impression mould 1 for forming parallel ribs in the layer of plaster 13 which is intended for attaching stone strips 8 against.
  • Said impression mould 1 is provided at least on one side 5 with parallel grooves 6 which are located at a distance A from each other.
  • the distance A between the parallel grooves 6 is slightly greater than the width E of the base 19 of the stone strips 8 to be applied.
  • the aforementioned distance A between the parallel grooves 6 is less than the side of the stone strips 8 to be applied that faces away from the layer of plaster 13.
  • the stone strips 8 are provided with two recesses 25in their base 19, respectively one on each of two opposite edges of the base 19.
  • the stone strips 8 are provided with one groove 6 in their base 19 located between, and parallel with, two opposite edges.
  • the impression mould 1 of the kit is made of a light material, preferably foam, for example polyethylene, foam-rubber or plastic foam.
