DESCRIPTION:
BRIEF SUMMARY
This Invention relates to tiles and floor surfaces in particular tiled surfaces e.g. floors, kitchen tops and other working surfaces.
The term tiles is intended to include floor elements such as wood blocks, bricks, tiles e.g. of ceramic or clay or concrete or brick, and paviours.
U.S. Pat. No. 1,643,879 discloses a method of forming a floor surface from tiles comprising laying the tiles on a substrate without adhesive beneath the tiles, and applying filler material between adjacent tiles after laying to hold the tiles in relative position.
According to one aspect of the invention a method of forming a floor surface from tiles comprises laying the tiles on a substrate without adhesive beneath the tiles, and applying filler material between adjacent tiles after laying to hold the tiles in relative position characterised in that the filler material is non-adhesive.
The tiles may be joined around their peripheries by the filler material.
The method may comprise laying a flexible sheet on the substrate and laying the tiles above the sheet.
The sheet may be apertured with filler material in the apertures.
A screed may be laid on the sheet and the tiles laid on the screed. The screed may be of filler material.
The filler material may be settable.
According to another aspect of the invention a tile for use in a method as above has a recess in a peripheral face for receipt of filler material characterised in that the recess has a re-entrant portion. The tile may have a recess e.g. a groove in an underface.
The invention includes a floor formed by a method as above.
The invention may be performed in various ways and some specific embodiments with possible modifications will now be described by way of example with reference to the accompanying schematic drawings in which:
FIG. 1 is a plan view of a floor;
FIGS. 1a to 1d show examples of patterns of laid tiles;
FIG. 2 and 3 are sections through parts of the floor;
FIG. 2a is a plan view of a spacer;
FIG. 4 is a perspective view of a tile;
FIG. 5 is a side view of part of a joint;
FIG. 6 is a perspective view of a tile;
FIG. 7 is a side view of part of a tile layer;
FIGS. 8 to 11a show other arrangements;
FIGS. 12 and 13 are plan and section views of a sheet;
FIG. 12A shows part of a sheet;
FIG. 14 is a section showing a clip; and
FIG. 15, 15A show a further arrangement.
Referring to the drawings, FIG. 1 shows parts of two side walls 10, 11 of a room and flooring 12 in the room. In laying the floor 12 a strip 13 of, for example, wood is laid against the bottom inner face 14 of wall 10. A plurality of flat floor elements 15, for example, wood blocks or bricks or tiles, are then laid on the surface which supports the floor, for example, a flat concrete base 9. The elements 15 are laid if desired in a pattern with adjacent elements abutting along their straight sides. After a certain length X of floor has been laid, a cross-member 17, for example of wood or L-shaped thin non-ferrous metal, is placed on the base 9 and moved to place the floor X under compression between strip 13 and the member 17 is then fixed in place, for example, by securing to the base 9 by bolts or screws or nails. The individual elements 15 are not secured to the base 9. Any small gaps between adjacent elements can be filled with a suitable filler e.g. non-cementitious grouting material for both thin and thicker elements. A grouting material, when it sets after filling, assists in holding the tiles in relative position. In some cases a suitably shaped plastics positioning spacer, with arms for example 2 mm or more wide, may be placed between adjacent elements 15, for example as in FIG. 2a.
This process is repeated until the floor is covered with a final strip similar to strip 13 adjacent the wall opposite wall 10.
The strips 13, 15 can be covered by decorative strips 20 (FIG. 3) or the adjacent elements 15 can be shaped to overlie the strips 13 (FIG. 2) or the joint 17 can be hidden (FIG. 5).
The distance X, FIG. 1 is selected such that the floor is not subject to unacceptable buckling.
The strip 13
