Definitions

• the present invention relates to an organ, which allows to maintain a spacing and a determined orientation between the different tiles of a tiled set.
• the invention also relates to a tiling method using the aforementioned spacer member.
• the word "tile” is used to designate not only the tiles of a tiled assembly, but also slabs that are to be placed side by side on a support while respecting alignments.
• the invention is in no way limited to use for ceramic tiles such as those used on kitchen or bathroom walls and it also relates to use for slabs of more large dimension.
• the tiles or slabs concerned by the present invention are of substantially rectangular shape, for example square.
• the tiles concerned are applied to a support with interposition of a bonding material consisting of cement and / or glue; the support to be tiled is coated with this bonding material and the tiles are placed on the support by pressing them sufficiently hard to obtain a good connection between the support and the tile.
• the tile setter encounters two problems: first, the tiles must have their visible outer face located in the same plane so that the tiled surface does not have bumps or depressions and secondly the spacing between two adjacent tiles must be substantially constant; if such spacing is variable, the tile assembly is unsightly and, furthermore, the alignment of the tiles is not respected.
• spacers that are placed in the areas to be covered by four angles of adjacent tiles.
• These spacer members comprise two elements that can form a single piece.
• the first element constitutes the rear part of the spacer member and has the shape of a ring which is placed between the support of the tile and the tiles, in the areas covered by four corners of tiles; this ring has a constant thickness, it maintains a constant spacing between the support of the tile and the rear face of the tile, which prevents the tile produced has bumps or depressions on its outer surface, the tiles having a thickness substantially constant and the support being substantially planar.
• the second element of this spacer member constitutes the front portion of said member and is formed of a cross comprising two equal and perpendicular branches, the branches of the cross being intended to come interposed between the tiles, to the right of an area where there are four adjacent tiles.
• the tiles are pushed, at the time of installation, against the branches of the spider, the width of these branches defining the spacing between the adjacent tiles of the tiled surface.
• the bonding material which maintains the tiles on their support, is put in place at the spacer member as on the rest of the surface of the support, so as to establish a connection between the spacer member, on the one hand, and the corners of tiles that it supports, on the other hand.
• the branches of the spider form with respect to the rear part of the spacer member an elevation, which is less than the thickness of the tiles, so that when filling by means of a joint material the intervals between tiles after the positioning of the tiles, the branches of the spacer member are no longer visible from the outside.
• a spacer member of the same type has already been described in the international application WO 2006/087572 which proposed to make the rear part of the spacer member according to a particular structure that allows easy and effective implementation of the connecting material for ensuring the maintenance of the spacer member on the support, on the one hand, and the maintenance of the tiles on the spacer member, on the other hand.
• the purpose of the invention is therefore to avoid the aforementioned drawback by proposing a spacer member in which, in line with said spacer member, two tiles must bear on abutments corresponding to the branches of a spider to define the orientation, while the other two have a set of positioning relative to the spacer member allowing the catching tolerances on the dimensions of the tiles in plan.
• This backlash ensures that the installer can correct the position of one tile in two in each alignment, which avoids the accumulation of dimensional discrepancies and therefore allows the realization of alignment, even with tiles with a slight dimensional variability.
• the subject of the present invention is therefore a spacer member of substantially rectangular tiles, all identical, arranged on the same support in adjacent rows parallel to two perpendicular axes, so that at least one angle of a tile is adjacent to three. angles of three other tiles, a layer of bonding material ensuring the maintenance of said tiles on the support after they have been properly positioned and a seal material filling the groove between two adjacent tiles, said member having a rear portion interposed between the tiles and the support and a front part which comprises elements interposed between adjacent tiles, said spacer member being positioned in line with the zones covered by four corners of tiles, the rear part of said member having the shape of a ring whose line average is a flat closed curve, characterized in that the rear portion supports four tabs, which constitute the front part and which are positioned on the ring, so as to define two by two four adjacent angular sectors centered on the central zone of the ring , the angular apertures of said sectors being close to 90 ° but being respectively smaller or greater than 90 ° when passing from one
• the ring constituting the rear part of the spacer member has a circle as a mean line; it can be provided that the tabs of the front part form a single piece with the rear part.
• the cross section of the ring perpendicular to its mean line, has the form of a V, whose point is on the side of the plane of its mean line where the tongues are not; of course, depending on the different possible laying cases, it is possible to envisage a V-shaped profile having a greater or lesser depth depending on the thickness of the layer of bonding material desired; the central part of the V-ring and the channel which constitutes the ring itself, are filled with connecting material to ensure a good connection of the corners of tiles with the support.
• the area of the tip of the V may have recesses allowing free passage on both sides of the tip of the V of the ring to allow the adhesive material to remain in place when at moment of the break, we move a little a tile relative to the spacer member.
• the tongues of the front part of the spacer member extend towards the tip of the V of the ring forming a partitioning inside the ring; each tongue may constitute, overhanging the rear part of the spacer member, a rectangular parallelepiped, whose faces perpendicular to the tip of the V of the ring to the right of the tongue, are in the extension of the partitioning; at least one of the parallelepipeds forming the tongues is separated into two flexible sheets by a slot perpendicular to the mean line of the ring in the zone of the tongue, this arrangement allowing, by deformation of a sheet, to increase the positioning set of a tile within an angular sector; the height of a tongue parallelepiped above the ring is less than the thickness of a tile of the tile to achieve.
• the large faces of the two tongues which are substantially spaced by 180 ° on the circle forming the average line of the ring, may be parallel to each other and perpendicular to the corresponding faces of the two other tongues; the distance from 90 ° angular openings of all angular sectors, can be substantially the same.
• the present invention also relates to a tiling method using spacer members as defined above, for producing a tile consisting of adjacent rows of tiles aligned along two perpendicular alignment axes, characterized in that:
• a grid of spacing members as defined above is placed on the support, the rings of which bear on the support, the lines of the grid being parallel to the axes of alignment of the adjacent rows of tiles, (T) of these bodies having, in the trigonometric direction from a point on one of the two alignment axes, a succession of sectors of small then large angular aperture while the other (R) have, in the retrograde direction, the same succession of sectors, the grid successively comprising on each of its lines a T-type member and then an R-type member, the tongues of the spacer members having their mean lines arranged parallel to one or the other the two alignment axes mentioned above;
• FIG. 1 shows in perspective a spacer member according to the invention
• FIG. 2A represents a section along AA of FIG. 1:
• FIG. 2B shows a section along BB of Figure 1;
• FIG. 3 represents a diagram relating to the laying of a tile according to the method of the invention, this diagram showing the positioning of five spacer members on a support, four of these members being distributed at the four corners of a tile, the alignment axes of the tiles being shown in dashed lines on the drawing;
• FIG. 4 shows in plan a detail diagram on which the angular difference with respect to 90 ° between a sector of small angular aperture and a sector of large angular aperture has been considerably enlarged for a better understanding of the efficiency of the system of laying according to the invention
• - Figure 5 shows, in perspective, a fractional view of a variant of a zone of the ring constituting the rear portion of the spacer member.
• the spacer member according to the invention comprises a circular ring designated 1 as a whole, said ring having in axial section the shape of a V, the tip of which. is intended to come to rest against the support on which one wants to achieve a tiling.
• the ring 1, which constitutes the lower part of the spacer member, thus forms a channel, which is separated into four successive sectors 2, 3, 4 and 5 by tabs 6, which project above the ring 1, said tabs extending inside the ring by a partition 6a_.
• the protruding part of the tongues 6 has the shape of a parallelepiped rectangle, whose planes of large faces are oriented towards the central zone of the ring 1 as will be specified later.
• one or more of the tabs 6 has its rectangular parallelepiped separated into two sheets by a slot 7 parallel to the two large faces, said slot extending over the entire height of the parallelepiped of said tongue and allowing a slight deformation in the direction of the thickness reduction to compensate if necessary expansion phenomena of the joint material.
• the four tabs 6 of the spacer member define between them four angular sectors, which have their vertex edges on the axis of the circular ring 1. This arrangement is clearly visible in FIG. 4 where the trace of the axis the circular ring is marked O. These four opposite angular sectors do not have the same angular aperture: two angular sectors 8b opposed by the apex have angular apertures equal to 90 ° - ⁇ , ⁇ being a small angle, whereas the other two angular sectors 8a_ have angular apertures of 90 ° + ⁇ .
• FIG. 4 shows this opening disparity: however, in FIG. 4, the angle ⁇ represented has been considerably enlarged with respect to the reality in order to show clearly the structure of the spacer member described and its cooperation with the tile tiles. .
• the tile tiles to achieve have been designated by 9, they are square and Figure 4 shows the angles of two tiles 9, as they are positioned between the tabs 6 above the angular sectors 8b.
• the sides of the tiles 9 bearing against the tabs 6 of a sector 8b have a well-defined position relative to the spacer member whose circular ring 1 has been partially shown in Figure 4.
• One of the tiles 9, which overhangs the spacer member in a sector 8a., Has been shown partially in dashed lines and it can be seen that the position of this tile with respect to the tongues 6, is not determined and therefore allows a slight clearance with point 0.
• This set designated by 14 in the drawing can be used to change the position of a tile 9 located in a sector with large annular opening, in the direction of the two axes 11, 12 which correspond to the two alignments tiling that we want to achieve.
• the tabs in this embodiment have their large faces parallel to the axes 11 and 12.
• the spacer members placed on the top and left corner and on the bottom and right corner of the single tile bearing the reference 9 in this figure have the same arrangement, that is, say that starting from the point of the ring 1 located on the alignment axis 11 and rotating on the ring in the trigonometric direction, there is successively a sector of small angular aperture and a sector of large angular aperture.
• This type of positioning has been designated by T in FIG. 3.
• R in Figure 3 On the other hand, at the other two angles of the same tile, if turns on the ring 1 of the spacer member from the point of intersection of the ring with the alignment axis 11, there is first a sector of large angular aperture and then a sector of small angular aperture; this arrangement has been designated R in Figure 3.
• the tile 9 has its four corners in sectors of large angular aperture, so that it can benefit from a positioning game without being flanged by the tabs 6 of the four spacers that frame it.
• the two adjacent tiles have their four angles arranged in sectors of small angular opening, so that they are clamped by the tongues 6 of these angular sectors and have no possibility of play.
• the use of spacers according to the invention therefore allows a tile in which one tile out of two, in each of the alignments corresponding to the alignment axes 11 and 12, is in a fixed position, while one tile out of two is in a position where it enjoys a set of positioning according to the two alignment axes 11 and 12.
• the spacer members allow a three-dimensional adjustment of the tiles by, firstly, the arrangement of the tabs 6 providing positioning in a plane (two dimensions) and, secondly, the presence of the V-shaped profile. whose greater or lesser depth will ensure the positioning of the tiles relative to the support in a direction perpendicular to said plane (third dimension).
• the placement of the tiles and spacers may therefore include relative movements of tiles, it has been planned to practice from place to place, recesses 13 in the tip. of the ring to allow free passage of the connecting material and thus ensure a good distribution of this material despite the movement of a tile.
• the depth of the V of the ring is chosen as a function of the thickness of the bonding material that it is desired to put in place between the support and the tiles 9.
• the grooves existing between the tiles 9 are filled with a material-joint, which makes disappear the tongues 6, the height of which is less than the thickness of the tiles 9.
