  The manufacturing method of this embodiment includes an adhesive application step, a tile placement step, and a removal step. Hereinafter, each process is demonstrated in order.

[Adhesive application process]
In the adhesive application step, as shown in FIG. 2, the adhesive 7 is applied to the release sheet 6 placed substantially horizontally on the work table 5. In the present embodiment, a masking material 9 having a plurality of openings 8 extending along the joint 4 in order to accurately apply the adhesive 7 along the joint 4 of the tile 3 to be disposed on the release sheet 6 later. Including a step of placing the material on the release sheet 6 and a step of applying the adhesive 7 on the release sheet 6 through the opening 8. Then, after the adhesive 7 is applied, only the masking material 9 is lifted upward and removed from the work table 5 as shown in FIG.

  As shown in FIG. 2, the work table 5 of the present embodiment includes a substantially horizontal and flat base surface 5 a and is formed in a substantially rectangular shape in plan view. When the tile unit 2 is manufactured on a manufacturing line or the like, the work table 5 may be provided on a belt conveyor or the like, for example.

  The release sheet 6 is formed, for example, in a substantially rectangular sheet having a release surface 6a on at least one surface, and is placed on the work table 5 with the release surface 6a facing up. Further, the release surface 6 a of the release sheet 6 may be provided with substantially L-shaped first marks M <b> 1 indicating the positions of the four corners of the masking material 9, for example. Such a first mark M1 serves to uniquely determine the position of the masking material 9 with respect to the release sheet 6.

  Further, the release sheet 6 is not particularly limited, but generally used papers such as synthetic paper, plastic sheets such as polyethylene, polypropylene, and polyethylene terephthalate can be appropriately employed.

  The adhesive 7 is composed of a moisture curable adhesive that cures by reacting with water vapor at room temperature and in the air. Although it can select suitably as a main ingredient of the adhesive agent 7, for example, it is preferable to consist of an epoxy resin with little volume shrinkage at the time of hardening and having the outstanding adhesive force. Thereby, the tile unit 2 with high accuracy is formed while stably connecting the tiles 3. Moreover, it is although it does not specifically limit as an epoxy resin, For example, the modified silicone epoxy and urethane epoxy which have favorable elasticity are preferable. Since the cured product 7A (shown in FIG. 1) has elasticity, such an adhesive 7 is flexibly deformed to absorb an external impact, and damage such as breakage is suppressed.

  The adhesive 7 is preferably filled with calcium carbonate in order to improve alkali resistance and cohesion. The breaking strength of the adhesive 7 after curing is preferably 1.7 N / mm 2 or more. As a result, the adhesive cured product 7 </ b> A can greatly improve durability and can stably connect the tiles 3.

  The masking material 9 of the present embodiment is formed in a single thin plate shape having an area slightly smaller than that of the release sheet 6, and is wider than the interval W1 (shown in FIG. 1) between the joints 4 along the joints 4. A plurality of openings 8 having a width L3 are provided. The thickness W2 of the masking material 9 is desirably formed substantially the same as the height H1 (shown in FIG. 1) of the adhesive 7 to be applied.

  Although it does not specifically limit as said masking material 9, For example, it can form with plastic materials, such as metal materials, such as iron, stainless steel, or an aluminum alloy, polyethylene resin, polypropylene resin. Further, in order to easily remove the cured product 7A (shown in FIG. 1) of the adhesive adhering to the surface of the masking material 9 when the adhesive 7 is applied, for example, a release agent such as fluorine or silicone (illustrated) (Omitted) is preferably coated.

  The masking material 9 is coated with the adhesive 7 in the opening 8 by using, for example, a caulking gun 14 or a roller (not shown). Since the opening 8 extends along the joint 4 (shown in FIG. 1), the adhesive 7 can be accurately applied to a predetermined position along the joint 4 without requiring skill. Furthermore, when the 1st mark M1 which shows the position of the four corners of the masking material 9 is attached | subjected to the release surface 6a of the release sheet 6 like this embodiment, the release sheet 6 and the masking material 9 are provided. Can also be easily aligned.

[Tile placement process]
In the tile placement step, as shown in FIG. 4, a plurality of tiles 3 are arranged on the adhesive 7 applied to the release sheet 6 with a space W1 between the joints 4.

  The tile 3 has, for example, a front surface 3a serving as a decorative surface, a back surface 3b facing the wall side opposite to the front surface 3a and forming an adhesive surface, and an outer surface 3c connecting the front surface 3a and the back surface 3b. It is a horizontally long rectangular shape. And in this embodiment, the back surface 3b of the tile 3 is distribute | arranged to the release sheet 6 side. As a result, each tile 3 is bonded to the outer surface 3c of the tile 3 by the adhesive 7, and a tile array 11 (shown in FIG. 5) connected to each other is formed on the release sheet 6. Since the adhesive 7 of the present embodiment has a width L3 (shown in FIG. 4) wider than the interval W1 of the joint 4, a part of the adhesive 7 wraps around the back surface 3b of the tile 3 to make the tile 3 stronger. Can be linked.

  As the tile 3, various sizes can be appropriately adopted. For example, a length L1 in the longitudinal direction of about 40 to 250 mm, a forehead dimension L2 of about 10 to 100 mm, and a thickness W3 of about 5 to 40 mm are preferable. . Moreover, although the material of the tile 3 is not specifically limited, for example, it is preferably made of porcelain such as porcelain, porcelain, or porcelain.

[Removal process]
In the take-out step, as shown in FIG. 5, prior to complete curing of the adhesive 7, the tile array 11 is lifted together with the release sheet 6 and taken out from the work table 5. At this time, it is desirable that the release sheet 6 is lifted while applying tension to the release sheet 6 from both side edges 6e and 6e of the release sheet 6 so that the arrangement of the tiles 3 does not collapse due to the bending of the release sheet 6. In order to effectively suppress such collapse of the arrangement, a thin plate-like support plate (not shown) such as cardboard having a surface area substantially the same as or slightly larger than that of the release sheet 6 is provided on the lower surface of the release sheet 6. ) May be arranged in advance and lifted while supporting it.

  As described above, in the manufacturing method of the present embodiment, the tile array 11 in which the adhesive 7 is not completely cured by being supported from below by the release sheet 6 is lifted and moved without breaking the array, and the mold release is performed. The sheet 6 can be taken out from the work table 5. Therefore, compared with the conventional manufacturing method in which the adhesive 7 is cured on the work table 5, the work method does not stay on the work table 5, and thus the productivity can be improved. Moreover, in the manufacturing method of the present embodiment, the tile unit 2 can be manufactured quickly and inexpensively without requiring skill.

  The manufacturing method according to the present embodiment includes a packing process in which the tile array 11 taken out from the work table 5 in the extraction process is accommodated in the packing box 12.

[Packing process]
In the packing process, as shown in FIG. 6, the tile array 11 taken out in the take-out process is accommodated in the packing box 12 in a substantially horizontal state with the release sheet 6 facing downward, To completely cure the adhesive 7. Since the adhesive 7 is a moisture-curing type, it reacts with water vapor in the air inside the packaging box 12 and is completely cured during storage and / or on-site transportation. Thereby, the tile unit 2 (shown in FIG. 1) including the plurality of tiles 3, the cured product 7 </ b> A of the adhesive that connects the tiles 3, and the release sheet 6 disposed on the back surface 3 b side of the tiles 3. Is manufactured.

  In the packaging box 12 of the present embodiment, one length L4 and the other length L5 are set so as not to disturb the arrangement of the tile array 11. In addition, in order to suppress the collapse of the arrangement of the tile array 11, for example, a partition plate 13 and a filler (not shown) are preferably arranged inside the packing box 12.

  In such a manufacturing method, since the tile array 11 in which the adhesive 7 is not completely cured can be packed in a box together with the release sheet 6 and transported to the construction site, the adhesive 7 is stored using the storage or transport time. Can be completely cured. Therefore, in the manufacturing method of this embodiment, the manufacturing period of the tile unit 2 can be shortened as compared with the conventional manufacturing method in which the adhesive 7 is cured in the factory.

  As a manufacturing method according to another embodiment, the tile array 11 taken out from the work table 5 in the take-out step is moved to a curing area (not shown) away from the work table 5 to cure the adhesive 7. A curing process may be included.

[Curing process]
In the curing process, the extracted tile array 11 is moved to the curing area in a substantially horizontal state with the release sheet 6 facing downward. Since the adhesive 7 is a moisture curing type, it is not necessary to put it in a high-temperature heating furnace and harden it as in the conventional manufacturing method. Therefore, in this manufacturing method, the adhesive 7 of the tile array 11 can be completely cured without causing the work-in-process to stay on the work table 5 in the curing area independent of the manufacturing line.

  Further, in the curing process, after the adhesive 7 is completely cured, the release sheet 6 is peeled off and the tile unit 2 is accommodated in the packing box 12. At this time, since the adhesive 7 of the tile unit 2 is completely cured, even if the release sheet 6 is removed, the arrangement of the tiles 3 does not collapse. Therefore, since the tile unit 2 is accommodated in the packaging box 12 in a state where the release sheet 6 is peeled off, the work of peeling the release sheet 6 can be omitted at the construction site, and the release sheet 6 needs to be discarded. Since there is no, workability can be improved.

FIG. 7 shows an embodiment in which the tile unit manufacturing method of the present invention is further streamlined.
In this manufacturing method, the positioning frame 17 having a plurality of openings 18 that can position the tiles 3 with respect to the adhesive 7 applied on the release sheet 6 in the tile arranging step is used as the release sheet 6. A step of placing the tile 3 in the opening 18, a step of attaching the back surface 3 b of the tile 3 to the adhesive 7 on the release sheet 6, and a step of fitting each tile 3, 8, a step of removing only the positioning frame 17 is included.

  For example, the positioning frame 17 is formed in a plate shape covering the release sheet 6 and has a substrate portion 17a in which a plurality of openings 18 are formed, and the substrate portion 17a is floated from the release sheet 6 at its four corners. And supporting leg portions 17b.

  In the present embodiment, the opening 18 of the substrate portion 17a is arranged in a horseshoe shape in accordance with the arrangement of the tiles 3 of the tile unit 2 with a predetermined interval W1 between the joints 4. Moreover, each opening part 18 hold | maintains the outer surface 3c of the tile 3 substantially continuously.

  The leg portion 17b is a prism having a substantially rectangular cross section, and supports the substrate portion 17a by floating from the release sheet 6 so that the lower surface of the substrate portion 17a does not come into contact with the adhesive 7.

  In addition, the work table 5 includes, for example, substantially L-shaped second marks M2 indicating the positions of the four corners of the release sheet 6 and third marks indicating the positions of the four corners of the leg portions 17b of the positioning frame 17. M3 is attached. With these second and third marks M2 and M3, the positions of the release sheet 6 and the positioning frame 17 can be relatively determined. In place of the second and third marks M2 and M3, a recess (not shown) into which a part of the release sheet 6 or the leg portion 17b can be fitted may be provided.

  By performing the tile placement process using the positioning frame 17 as described above, the tiles 3 can be easily and accurately arranged with the space W1 between the joints 4, and the productivity of the tile unit 2 can be further improved. . Furthermore, in this embodiment, since the positioning frame 17 and the release sheet 6 are accurately aligned with the work table 5, the tile 3 can be accurately arranged with respect to the adhesive 7.

FIG. 9 shows a positioning frame 17 of still another embodiment.
The positioning frame 17 of this embodiment includes a plurality of gripping portions 26 that intermittently hold the outer surface 3c of the tile 3, a connecting portion 27 that connects the gripping portions 26, and the gripping portion 26 and the connecting portion 27. And leg portions 28 arranged to float from the release sheet 6.

  The grip portion 26 of the present embodiment is formed in a columnar shape having a diameter L9 that is substantially the same as the interval W1 of the joint 4 (shown in FIG. 7), and the upper end thereof is formed in a tapered shape. This eliminates resistance when the tile 3 is inserted from above the positioning frame 17 and improves workability. Further, a plurality of gripping portions 26 (six in this example) are arranged for one tile 3 and hold the outer surface 3 c of the tile 3. Further, the lower end of the grip portion 26 is located above the release sheet 6 and the adhesive 7.

  The connecting portion 27 is made of a rib material having a thickness smaller than the interval W1 of the joint 4, extends outside the joint 4 and the positioning frame 17, and connects the adjacent gripping portions 26 to each other.

  Such a positioning frame 17 can also easily and accurately arrange the tiles 3 with the interval W1 between the joints 4, and can further improve the productivity of the tile unit 2. Moreover, since the upper end of the holding part 26 is formed in a taper shape, the positioning frame 17 of the present embodiment can easily fit the tile 3 into the positioning frame 17 from above. Further, since the gripping portion 26 intermittently holds the outer surface 3c of the tile 3, the friction between each tile 3 and the gripping portion 26 can be minimized, and as shown in FIG. It can be removed from the tile 3 smoothly and removed upward.

FIG. 11 shows a method for manufacturing a tile unit according to still another embodiment of the present invention.

Including. Further, the release sheet 6 has a plurality of through holes 6 b (shown in FIG. 12) corresponding to the pins 31.

  The pin 31 of the present embodiment has a diameter D1 that is substantially the same as the interval W1 of the joint 4. The pin 31 is set to have a height H2 lower than the thickness W3 of the tile 3, for example, and is fixed to the base surface 5a of the work table 5. Further, since the pins 31 are arranged along the joints 4, they can be used not only as positioning of the tiles 3 but also as positioning members when applying the adhesive 7.

  In the manufacturing method of the present embodiment, the release sheet 6 is placed on the work table 5 by inserting the pin 31 into the through hole 6 b in the adhesive application step. Next, the adhesive 7 is applied between adjacent pins 31 along the joint 4. Thereafter, in the tile placement step, the tile array 11 (shown in FIG. 12) is formed by placing the tile 3 in contact with the pin 31. In the extraction step, as shown in FIG. 12, the tile array 11 can be supported and lifted by the release sheet 6 and removed from the work table 5 while removing the pins 31 from the through holes 6 b.

  As described above, in the manufacturing method of the present embodiment, the application position of the adhesive 7 and the tile are formed only by the pins 31 without using the masking material 9 (shown in FIG. 2) and the positioning frame 17 (shown in FIG. 7). 3 can be uniquely determined, so that productivity can be further improved. The adhesive 7 may be applied by fitting a pin 31 into the opening 8 of the masking material 9 shown in FIG.
