Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the method for constructing the tile wall 10 of the present embodiment includes a step of applying an adhesive 4 to a wall base 3 of a structure such as a house or a building (hereinafter referred to as “adhesive application step”). And a step of affixing the tile unit 1 in which a plurality of tiles 2 are connected in advance to the wall base 3 to which the adhesive 4 is applied (hereinafter also referred to as an “applying step”). Is included.

  As shown in FIGS. 1 and 2, the tile unit 1 includes a plurality of tiles 2 and tile connecting means 5 that connects the plurality of tiles 2 with the joint spacing S maintained. In the present embodiment, a vertical joint 6A extending up and down between the tiles 2 and 2 adjacent to the left and right, and a joint including a horizontal joint 6B including the vertical joint 6A and extending horizontally between the tile groups 2G and 2G adjacent to the top and bottom. Twelve tiles 2 are arranged in a stepping pattern across 6. Note that the number of tiles 2 connected and the joint shape may be variously changed.

  The tile 2 has a front surface 2a that is a decorative surface, a back surface 2b that is attached to the opposite side of the front surface 2a and substantially parallel to the wall base 3, and a space between the front surface 2a and the back surface 2b in the tile thickness direction. The side surface 2c that forms the joint 6 is provided, and in the present embodiment, it is formed in a substantially rectangular shape that is horizontally long when viewed from the front.

  The tile 2 can be appropriately selected in various sizes. For example, the length L1 in the longitudinal direction is about 40 to 250 mm, the edge dimension L2 is about 10 to 100 mm, and the thickness W1 (shown in FIG. 3). The thing of about 5-40 mm is preferable. Further, the material of the tile is not particularly limited, but for example, ceramics such as ceramics, porcelain, and porcelain are preferable.

  The tile connecting means 5 of the present embodiment is made of a cured product of an adhesive 7 having the same color tone as the adhesive 4 applied to the wall base 3 and containing the same main agent as the main agent of the adhesive. The “same color tone” may be an extent that is difficult to distinguish when the adhesives 4 and 7 after curing are visually recognized with the naked eye.

  Further, the tile connecting means 5 of this embodiment is arranged along the upper vertical joint 6Au located on the uppermost side of the vertical joints 6A, the lower vertical joint 6Ad located on the lowermost side, and all the horizontal joints 6B. A total of seven are provided. Since the tile connecting means 5 is formed in an elongated shape arranged in substantially the entire range of the joint lengths of the joints 6Au, 6Ad, and 6B, the tiles 1 and 2 can be firmly connected to each other. The durability performance can be improved.

  Here, “arranged over substantially the entire range of the joint length” means that the length L3 along the joint of the tile connecting means 5 is equal to the joint length L4 in consideration of errors before and after the adhesive 7 is cured. It shows that it is arranged in the range of 90 to 110%.

  As shown in FIGS. 2 and 3, the tile connecting means 5 of the present embodiment includes a base portion 11 that straddles between the side surfaces 2 c and 2 c of adjacent tiles 2 and a protruding portion that covers at least a part of the back surface 2 b of the tile 2. 12.

  The base portion 11 of the present embodiment is disposed on the back surface 2b side of the tile 2 and straddling the side surfaces 2c of the adjacent tiles 2 and 2. Further, the maximum thickness W2 of the base 11 is formed smaller than the thickness W1 of the tile 2. Thereby, in the base portion 11, a space 14 is formed on the front surface 2 a side of the tile 2. The protruding portion 12 extends from the base portion 11 in the joint width direction with a substantially constant thickness, and is formed integrally with the base portion 11 so as to cover a part of the back surface 2b.

  In the tile connecting means 5 of the present embodiment, the maximum thickness W3 from the back surface 2b of the tile 2 of the base portion 11 and the protruding portion 12 is limited to 0.1 mm or less. As a result, in the tile connecting means 5, the base portion 11 and the protruding portion 12 are formed substantially flush with each other on the back surface 2 b of the tile 2.

An example of the method for forming the tile unit 1 as described above will be described.
In the present embodiment, as shown in FIG. 4, a tray 16 that can arrange a plurality of tiles 2 with the joint spacing S maintained is used.

  The tray 16 includes a plate portion 18 that receives the front surface 2 a of the tile 2, and a convex frame portion 17 that protrudes from the plate portion 18 and can position adjacent tiles 2 at the joint spacing S. The height D1 of the frame portion 17 is set to a thickness (W1-W2) obtained by subtracting the maximum thickness W2 (shown in FIG. 3) of the base portion 11 from the thickness W1 of the tile 2. Further, the material constituting the tray 16 is not particularly limited, and for example, it can be formed of a metal material such as iron, stainless steel, or an aluminum alloy, or a plastic material such as polyethylene resin or polypropylene resin.

  A plurality of tiles 2 are arranged on the tray 16 with the front surface 2a of the tiles 2 facing down. As a result, the plurality of tiles 2 are positioned and arranged with the correct joint spacing S. Further, since the height D1 of the frame portion 17 is smaller than the thickness W1 of the tile 2, as shown in FIG. 5, when the tile 2 is disposed, the groove portion 21 in which the adhesive 7 can be disposed on the joint 6 is provided. Is formed.

  Thereafter, the adhesive 7 is applied to the groove portion 21 across the tiles 2 in a strip shape. The adhesive 7 can be applied efficiently by using a roller (not shown) or the like in addition to using the caulking gun 22 as in this embodiment. After the adhesive 7 is applied, the back surface 2b side of the tile 2 is leveled with a roller or the like so that the adhesive 7 and the back surface 2b of the tile 2 are substantially flush with each other, and both sides of the adhesive 7 are arranged. As a result, the protruding portion 12 (shown in FIG. 2) is formed.

  Then, after the adhesive 7 is cured, the plurality of tiles 2 and the tile connecting means 5 are integrally removed from the tray 16 to form the tile unit 1. In order to make this removal work more efficient, a release agent (not shown) such as fluorine or silicone is applied to the upper surface 17a of the frame 17 to prevent adhesion with the adhesive 7. preferable.

  By forming the tile unit 1 using such a tray 16, the adhesive 7 can be accurately and easily disposed across the side surfaces 2 c and 2 c of the tile 2, and the adhesive 7 is disposed on the front surface 2 a of the tile 2. Can prevent dripping to the side. Therefore, the tile unit 1 can be easily formed with high accuracy and without impairing the appearance.

  Next, an example of the construction method of the tile wall 10 will be described.

  In the adhesive application step, as shown in FIG. 6A, the adhesive 4 is applied to the wall base 3 with a thickness W5 of about 1.5 to 2.0 mm, for example. The adhesive 4 may be filled with calcium carbonate from the same viewpoint as the adhesive 4.

  Next, in the affixing step, as shown in FIG. 6B, the back surface 2b of the tile 2 and the tile connecting means 5 are brought into contact with the adhesive 4 applied to the wall base 3, so that the tile unit 1 Is affixed to the wall base 3.

  Since the base 11 and the protruding portion 12 are formed substantially flush with each other on the back surface 2b of the tile 2, as in the conventional case shown in FIG. 10 (b), the tile connecting means b protrudes greatly from the back surface 2b side. The adhesive d is not pushed down locally. Therefore, as shown in an enlarged view in FIG. 7, the tile unit 1 can bring the tile 2 and the tile connecting means 5 into contact with the adhesive 4 without a gap.

  Thus, in this invention, since it can suppress that the clearance gap f (shown in FIG.10 (b)) is formed between the tile 2 and the adhesive agent 4, the adhesiveness of the tile unit 1 can be improved. At the same time, it is possible to suppress the deterioration of the tile 2 and the tile connecting means 5 due to rainwater and dew condensation remaining in the gap f, so that the durability performance can be improved.

  Further, in the tile connecting means 5, the protruding portion 12 can increase the adhesion area between the tile 2 and the tile connecting means 5 and firmly connect the adjacent tiles 2 and 2. Thereby, since the surface rigidity of the tile unit 1 is increased and the shape thereof is stabilized, the workability can be improved.

  Further, the tile connecting means 5 is made of a cured product of an adhesive 7 having the same color tone as that of the adhesive 4 of the wall base 3 and containing the same main agent as the main agent of the adhesive 4. Can be increased. Therefore, the tile unit 1 can improve the adhesion to the wall base 3. Moreover, after they are integrated, it is difficult to distinguish the two from the joints of the tile 2 and there is no difference in the progress of each deterioration, so that the aesthetic appearance of the tile wall 10 (shown in FIG. 1) can be maintained over a long period of time. Can improve.

  In order to effectively exhibit the above action, the maximum thickness W3 (shown in FIG. 3) of the base portion 11 and the protruding portion 12 is more preferably 0.1 mm or less, and still more preferably 0.08 mm or less. desirable.

  Further, in order to enhance the prevention of breakage of the tile connecting means 5 due to impact or load during transportation or construction, the maximum thickness W2 of the base 11 (shown in FIG. 3) is preferably 0.5 mm or more, more preferably Is preferably 1 mm or more. On the other hand, when the maximum thickness W2 is excessively large, the unevenness between the tile 2 and the joint 6 is reduced in front of the tile wall 10 (shown in FIG. 1), and the three-dimensional feeling and the solid feeling are lowered, and the aesthetic appearance is reduced. There is a risk that the mass of the tile unit 1 will increase significantly. From such a viewpoint, the maximum thickness W2 is preferably 2 mm or less, more preferably 1.5 mm or less.

  Further, in the protruding portion 12, when the maximum width L5 in the joint width direction is excessively increased on the back surface 2b of the tile 2, the bonding surface between the back surface 2b of the tile 2 and the adhesive 4 applied to the wall base 3 is reduced. There is a possibility that the adhesive strength of the tile unit 1 cannot be exhibited sufficiently. Conversely, if the maximum width L5 is excessively small, the adjacent tiles 2 and 2 may not be firmly connected. From such a viewpoint, the maximum width L5 is preferably 1 mm or less, and more preferably 0.8 mm or less.

  The main agent of the adhesive 7 can be selected as appropriate. For example, the adhesive 7 is preferably made of an epoxy resin having a small volume shrinkage at the time of curing and having an excellent adhesive force. Thereby, the tile connection means 5 can form the tile unit 1 with high accuracy while stably connecting the tiles 2.

  Furthermore, the epoxy resin is not particularly limited, but, for example, a modified silicon epoxy or urethane epoxy having good elasticity is preferable. Since the tile connecting means 5 made of the adhesive 7 has elasticity, the tile connecting means 5 can be deformed flexibly to absorb external impacts and suppress damage such as breakage.

  The adhesive 7 is preferably filled with calcium carbonate in order to improve alkali resistance and cohesion. Further, the breaking strength of the tile connecting means 5 is desirably 1.7 N / mm 2 or more. Thereby, the tile connection means 5 can further improve the prevention of breakage, and can stably connect the tiles 2.

  As shown in FIG. 3, the side surface 2c of the tile 2 includes a main side surface 26 that extends at a right angle to the front surface 2a and extends to the back surface 2b, and a chamfered portion 27 in which a corner portion between the main side surface 26 and the back surface 2b is cut obliquely. It is preferable to form from. By adhering at least a part of the tile connecting means 5 to the chamfered portion 27, the adhesion area between the tile 2 and the tile connecting means 5 can be increased, and the adjacent tiles 2 and 2 can be more firmly attached. Can be linked.

  If the maximum chamfering height H1 in the tile thickness direction of the chamfered portion 27 is too small, the adhesion area between the tile 2 and the tile connecting means 5 may not be increased. On the contrary, if the maximum chamfering height H1 is excessively increased, the strength of the tile 2 is decreased and the durability performance of the tile unit 1 may be deteriorated. From such a viewpoint, the maximum chamfering height H1 is preferably 0.5 mm or more, more preferably 1.0 mm or more, and preferably 2.0 mm or less, more preferably 1.5 mm or less. .

  From the same viewpoint, the maximum chamfering width W6 of the chamfered portion 27 in the joint width direction is preferably 0.5 mm or more, more preferably 1.0 mm or more, and preferably 2.0 mm or less, more preferably 1 .5mm or less is desirable.

  The tile connecting means 5 is not limited to one that is formed in a long shape extending along the joint 6 of the tile 2 as shown in FIGS. 1 and 2. Since the tile connecting means 5 of the present invention can firmly connect adjacent tiles 2 and 2 by the base 11 and the protruding portion 12 as described above, for example, as shown in FIG. The tiles 2 and 2 may be partially connected. Such tile connecting means 5 can reduce the amount of the adhesive 7 while stably connecting the tiles 2. Needless to say, the tile connecting means 5 may be a mixture of such a partial connection and a long one.

  Furthermore, although the tile connection means 5 showed what consists only of the hardened | cured material of the adhesive agent 7, as shown to Fig.9 (a), the reinforcement material 28 which improves the intensity | strength may be included, for example.

  The reinforcing material 28 of the present embodiment is formed in a thin plate shape having a thickness W7 smaller than the maximum thickness W2 of the base portion 11, and is arranged on the wall base 3 (shown in FIG. 7) side of the base portion 11. Further, the reinforcing material 28 is provided on the back surface of the tile 2 by indenting the reinforcing material 28 into the base 11 by smoothing the adhesive 7 and the reinforcing material 28 with a roller or the like before the adhesive 7 is cured. It is formed substantially flush with the 2b side.

  Such a reinforcing material 28 can improve the strength of the tile connecting means 5 and suppress damage such as breakage. Therefore, the durability performance of the tile unit 1 is improved. Further, even if the tile connecting means 5 includes the reinforcing material 28, the tile connecting means 5 is formed substantially flush with the back surface 2 b side of the tile 2, so that the adhesion with the wall base 3 is not lowered. Furthermore, since the reinforcing material 28 is hidden by the base 11, the aesthetic appearance of the tile wall 10 (shown in FIG. 1) is not impaired.

  If the thickness W7 of the reinforcing member 28 is reduced, the strength of the tile connecting means 5 may not be sufficiently improved. Conversely, when the thickness W7 increases, the amount of penetration into the base portion 11 increases, and the base portion 11 may be greatly deformed. From this point of view, the thickness W7 is preferably 30% or more, more preferably 35% or more of the maximum thickness W2 of the base 11, and preferably 45% or less, more preferably 40% or less. Is desirable.

  Further, the reinforcing member 28 is not limited to such a thin plate shape, and may be formed from, for example, fibers (not shown) in which organic fibers are formed in a cord shape. Such a reinforcing member 28 improves the strength of the tile connecting means 5 and does not increase the mass of the tile unit 1 as compared with a thin plate made of metal. Furthermore, since such a reinforcing material 28 has a small amount of penetration into the base portion 11, deformation of the base portion 11 and the protruding portion 12 can be suppressed. In addition, although it does not specifically limit as a fiber, For example, it is desirable to select organic fibers, such as an aramid and nylon, suitably.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.

Next, an embodiment that further embodies the present invention will be described. In this example, as shown in FIG. 4, tiles made of ceramics were arranged with the back side up, using a tray on which tiles could be arranged while maintaining a joint spacing of 5 mm. Thereafter, as shown in FIG. 5, the adhesive A was applied. The adhesive was cured for 8 hours until it was completely cured. By removing from the tray, a tile unit having tiles and tile connecting means shown in Table 1 was manufactured. The common specifications are as follows.
tile:
Length L1: 145mm
Small dimension L2: 45mm
Thickness W1: 11mm

Next, as a tile wall construction method, the adhesive B was applied to a wall base made of pulp-mixed cement calcium silicate board with a thickness of 1.5 mm, and the tile unit was attached to the wall base. The performance of each tile wall was evaluated. Table 2 shows the composition of the adhesive A forming the tile connecting means and the adhesive B applied to the wall base, and the breaking strength after curing.
The test method is as follows.

<Adhesion>
Before the adhesive B was cured, the tile unit attached to the wall base was peeled off, and the area of the adhesive B attached to the back surface of the tile was measured. The results were expressed as an index with the area of the comparative example as 100. The larger the value, the smaller the gap and the better the adhesion.

<Adhesive strength of tile connecting means and crack strength of tile>
The adhesion strength of the tile connecting means of each test tile unit and the crack strength of the tile were measured, and the comparative example was displayed as an index of 100. The larger the value, the better the durability.

  In the tile wall construction method of the example, it was confirmed that the adhesion to the wall base and the durability performance could be improved.
