Description

[Detailed explanation of the idea] The present invention relates to improvements in unit tiles.

In recent years, various unit tiles have been proposed in order to streamline the construction of ceramic tiles, and among these, in particular, the ceramic tiles are bonded onto a flexible adhesive rubber sheet, hard or semi-hard sheet, etc. as a base material. Unit tiles are the most popular.

However, in the above-mentioned unit tiles, the joint treatment method relies on the traditional joint filling work at the construction site using joint cement, but the necessity of such a wet method complicates the work and is not desirable. .

In this case, if the joint filling with joint cement could be done in advance during the unit tile manufacturing process, it would be possible to omit the complicated wet work at the construction site, which would be very preferable from a construction perspective, but for the following reasons. This cannot be realized due to

In other words, if unit tiles are filled with cement-based joints during factory production, the cement joints may break or fall off due to vibrations and shocks during transportation during the distribution stage after shipment from the factory, or vibrations and shocks during construction. Occurs frequently.

On the other hand, various techniques have been proposed to improve the drawbacks of cement-based joints that are susceptible to vibrations and shocks, in which elastic or flexible liquid polymers are poured into the joints and then hardened. Because it is an organic type, its durability and stain resistance are greatly inferior, and the permanent beauty, durability, and fire resistance that ceramic tiles originally have are lost at the joints, so they are not put into practical use. This has not yet been achieved.

Furthermore, if the joints are formed in advance, the joints between each unit will be noticeable when the unit tiles are constructed, requiring troublesome post-processing such as concealing the joints.

The present invention was made with the aim of eliminating all of these conventional problems. Specifically, the present invention consists of a base material 1 and a ceramic bonded to the surface of the base material 1 with a joint spacing 2. In a unit tile consisting of tiles 3, the joint spacing 2 is formed between each ceramic tile and on the periphery of the base material, and a joint 4 is previously formed in this joint spacing 2, and this joint 4 is formed between the base material 1. It is composed of inorganic granules 4a spread and attached to the surface, and a part of the inorganic granules 4a spread and attached to the joint interval 2 on the peripheral edge of the base material protrudes outward from the joint edge of the base material. The present invention relates to a unit tile with joints.

The figure shows a preferred embodiment of the present invention in which a reinforcing net 7 is placed on the top surface of a base material 1 made of an adhesive non-vulcanized butyl rubber sheet (thickness 1 mm) whose back side is protected by a release sheet 5. Apply adhesive 6 (two-component reaction-curing polyurethane adhesive) to the entire surface from 0.3 to 0.5+n.
m thickness until it begins to harden (20 minutes after application)
Within minutes), the ceramic tile 3 is adhered to the adhesive surface 6 with a predetermined joint interval 2, and the joint interval 2 is
crushed ceramics (product name: Color High Star, particle size: 0
．． 5 to 1.5 mm, manufactured by Showa Mining Co., Ltd.) are scattered and attached to form joints 4,
Thereafter, this was heated at 70° C. for 115 minutes to harden the adhesive 6, resulting in a jointed unit tile.

In the present invention, the base material 1 is not limited to what is shown in the drawings, and other organic or inorganic fabrics, films, sheets, boards, etc. can be used alone or in combination.

Furthermore, although the ceramic tiles 3 are arranged in five rows in parallel with each row being shifted by half a pitch in vertical rows of sets of three, the number of tiles to be used and the state in which they are arranged in parallel are not particularly limited.

Further, the adhesive 6 is not particularly limited as long as it can bond the base material 1 and the ceramic tile 3; for example, a reaction curing type,
Organic adhesives such as dry curing type and hot melt type can be advantageously used.

The adhesive 6 does not necessarily need to be used when the base material 1 itself has adhesive properties to the ceramic tiles 3, such as when the base material 1 is composed of an adhesive rubber sheet. Even in such a case, when a two-component reaction curing adhesive is used as shown in the figure, good water-resistant adhesive strength can be obtained.

Further, as the inorganic granules 4a, natural or artificial sand grains, crushed natural or artificial stones can be used, and the particle size is 0.1 to 5 mm.
, preferably about 0.5 to 2.0 mm, can be advantageously used.

The inorganic granules 4a may be bonded using the adhesive 6 for bonding the ceramic tiles 3 as shown in the figure, or may be bonded using a separate adhesive.

The inorganic granules 4a are spread and attached so as to substantially cover the entire surface of the joint interval 2, thereby forming a joint 4.

The unit tile of the present invention has 4 joints in advance at 2 joint intervals.
is formed, so there is no need for complicated joint treatment work such as filling the joints with joint cement during construction.
This simplifies tile construction and significantly improves work efficiency.

Furthermore, since the granular material 4a constituting the joint 4 is inorganic, its appearance and texture harmonize well with those of the ceramic tile 3, and not only can it exhibit an excellent decorative effect as a joint, but it is also inorganic and resistant to stains and stains. Since it does not fade or fade, this excellent decorative effect can be maintained semi-permanently and is highly durable.

Furthermore, since it is inorganic, it also has excellent fire retardant properties.

Furthermore, as the inorganic granules 4a, those with various tones and colors are easily available, and the tones and colors can be expressed freely, so the joints 4, which have high design value, can be matched to the tones and colors of the ceramic tiles. can be easily and selectively formed.

Furthermore, among the inorganic granules 4a forming the joint 4, the granules 4a' attached to the periphery of the unit tile have a portion extending outward from the joint edge, as shown in FIG. Since it bites out, the granules 4d camouflage the joints when unit tiles are joined, and a joint with a good appearance similar to that produced on-site by the wet method 1 can be obtained without troublesome post-processing such as concealing the joints.

Furthermore, since the joints 4 are formed in advance during factory production of the unit tiles, it is possible to perform sufficient quality control, and there is no occurrence of uneven strength of the material itself due to variations in the mixing process, as seen with wet joint materials. Uniform, high-quality joints can be formed stably and reliably.

Furthermore, since the inorganic granules 4a constituting the joints 4 are spread and attached at the joint spacing 2, each grain is adhered independently, and each individual particle has a high adhesive strength and is free from vibrations during transportation and construction. It can withstand shock and impact well, and there is no danger of it falling off.

In addition, since the granules 4a are attached individually and independently in this way, even if a flexible material is used as the base material 1, the folding in the two joint spaces of the base material 1 will not occur. There is no risk of impairing bendability at all, and the ease of construction, which is an advantage of using the flexible base material 1, can be maintained.

In this way, the unit tile of the present invention has joints that do not require hidden seams, so not only can tile construction be streamlined, but the joints 4 have impact resistance, vibration resistance, durability, fire resistance, and It has excellent qualities such as stain resistance and excellent decorative properties unique to inorganic materials, and has features that can significantly improve the usefulness of this type of unit tile.
