BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a method for installing an exterior tile and a bonding structure of the exterior tile according to the present invention will be described in detail with reference to the drawings. First, a method for constructing an exterior tile according to the first embodiment of the present invention will be described. Note that the same reference numerals as those used in the description of the conventional exterior tile construction method are used in the drawings.

In the method for installing an exterior tile according to the first embodiment, first, an adhesive 3 is applied to the outer surfaces of one and the other siding boards 2a and 2b, which are one and the other bases, as before. . The range in which the adhesive 3 is applied is limited to one and the other siding boards 2a, 2a.
b is not necessarily the whole, and may be performed in an appropriate range from the curing time of the adhesive and the time required for the bonding step of the exterior tile, and the like, and the joint portion between the one and the other siding boards 2a and 2b may be formed. No need to consider. Then, when the work of applying the adhesive 3 in an appropriate range is completed, the exterior tiles are then bonded. FIG.
It is a top view which shows the middle of such an exterior tile adhesion | attachment process, The code | symbol 3 shown by oblique line is the adhesive agent apply | coated to the outer surface of said one and other siding boards. Here, the exterior tile 4 covering the joint between the one siding board 2a and the other siding board 2b
An adhesive tape is attached to a part of the back surface of each of c, 4f, 4j, and 4m. FIG. 2 shows the exterior tile 4f (4m).
FIG. 3 is a back view of the siding board 2 on the back side of the exterior tile 4f (4m).
The adhesive tape 5 is affixed to a portion having a small area with respect to the seam portion 2c between a and 2b. The adhesive tape 5 has one surface coated with an adhesive (not shown) and the other surface coated with a resin. That is, in the method for constructing an exterior tile according to the first embodiment, the seam portion 2c of the one and the other siding boards 2a and 2b, like the exterior tile 4f (4m).
The adhesive tape 5 is applied in advance to the back surface of the exterior tiles 4c, 4f, 4j, and 4m having a small area with the joint 2c as a boundary, and the adhesive tape 5 is applied. Exterior tiles 4c, 4f, 4j,
4 m is bonded via the adhesive 3. Therefore, the width of the adhesive tape 5 attached to the back surface differs depending on the individual exterior tiles 4c, 4f, 4j, 4m (however, the exterior tiles (the reference numerals are omitted) as shown in FIG. 1).
If the adhesive is stuck in a staggered order, the exterior tile 4
The lengths of the adhesive tapes 5 adhered to c and 4j are the same, and the lengths of the adhesive tapes 5 adhered to the exterior tiles 4f and 4m are the same. ).

Accordingly, one of the exterior tiles 4a... 4m is subjected to the above-described steps, and one of the exterior tiles 4c, 4f, 4j, and 4m on the seam portion 2c of the tile siding boards 2a and 2b. By sticking the adhesive tape 5 to a portion having a small area with the seam portion 2c of the other siding boards 2a and 2b as a boundary, and sticking only a portion having a large area via an adhesive,
Even when the one and the other siding boards 2a, 2b shrink or the structure is deformed by an earthquake or a typhoon, a crack C as shown in FIG. 11 is formed in the exterior tiles 4c, 4f, 4j, 4m. This can be prevented from occurring. In the above-described embodiment,
The exterior tiles 4c, 4f, 4j,
Although an example in which the adhesive tape 5 is adhered to the back surface of 4 m is illustrated and described, these exterior tiles 4 c, 4 f, 4 j, 4 m
The back surface is not limited to such an adhesive tape 5, but may be an application method in which, for example, an oil wax (not shown) is applied in advance, and then bonded via the adhesive 3.

Next, a method for installing an exterior tile according to a second embodiment of the present invention will be described. First, as shown in FIG. 3, one and the other siding boards 2a, 2a
The adhesive 3 is applied to both left and right sides of the seam portion 2c of b as shown by hatching in FIG. 3 (first adhesive application step). The range of the adhesive 3 is the same as that of the joint 2
It suffices that the length is at least half the length of the exterior tile (symbols are omitted) in the left-right direction in FIG. 3 from c. When the first adhesive application step is completed, the process waits until the adhesive 3 is cured (adhesive curing step). When the adhesive is cured, the one siding board 2a or An adhesive (not shown) is applied again to the other siding board 2b (second adhesive application step),
Before the adhesive is cured, as shown in FIG. 4, the seam portion 2 of the one and the other siding boards 2a, 2b
Exterior tiles 4a, 4b, 4d, 4e, 4g, 4h, 4i, 4 other than exterior tiles (reference numerals are omitted) related to c.
k, 41, 4n, 40, 4p, 4r, 4s, and 4u are bonded (first exterior tile bonding step). By the end of this step, only the exterior tiles (symbols are omitted) on the joint portions 2c of the one and other siding boards 2a, 2b are left unbonded without being bonded.

When the first exterior tile bonding step is completed, the back side of the exterior tile (reference numeral is omitted) on the seam portion 2c of the one and other siding boards 2a and 2b is then obtained. As shown in FIG. 5, an adhesive 3 (shown by a hatched portion in FIG. 5) is applied to a portion having a large area on both sides of the joint portion 2c.
Adhesion is performed between the exterior tile and the exterior tile that have already been bonded (second exterior tile bonding step). That is, the exterior tile 4f or the exterior tile 41 and the exterior tile 4l bonded between the exterior tile 4e and the exterior tile 4g shown in FIG.
In the case of the exterior tile 4m (exterior tile f and exterior tile m both refer to FIG. 9) bonded between
As shown in the back view of the exterior tile 4f (4m) shown in FIG.
The adhesive 3 is applied to a wide area on both sides of the joint 2c as a boundary, and the adhesive is not applied to a narrow area, and the space between the exterior tile 4e and the exterior tile 4g (or exterior (Between the tile 41 and the exterior tile 4n). In addition, when bonding the exterior tiles 4b and the exterior tiles 4d and the exterior tiles (the reference numerals are omitted) that are bonded between the exterior tiles 4h and the exterior tiles 4i, both sides of the seam portion 2c as a boundary are also used. Adhesive is applied to a large area (exterior tile 4d or exterior tile 4i side) inside, and adhesive is applied to a narrow area without applying an adhesive.

In the method described above, after the adhesive curing step, an adhesive (not shown) is applied again to one of the siding boards 2a and the other siding board 2b (second adhesive applying step). Before the agent cures,
Exterior tiles 4a, 4b, 4d, 4e, 4g, 4h, other than exterior tiles (reference numerals are omitted) on the seam portion 2c of the one and other siding boards 2a, 2b.
4i, 4k, 41, 4n, 4o, 4p, 4r, 4s, 4
Although the method of bonding u (first exterior tile bonding step) has been described, a method described below (third embodiment) may be employed instead of such a method. In this method, after the adhesive curing step, as shown in FIG. 6, the adhesive 3 is applied again to the one siding board 2a (second adhesive applying step), and the adhesive 3 is cured. Before, as shown in FIG. 7, one siding board 2
a, the one and other siding boards 2a, 2b
Exterior tiles 4a, 4b,
4e, 4h, 4i, 4l, 4o, 4p, and 4s are bonded together and are exterior tiles bonded to the seam portion 2c. The exterior tiles 4f, 4m, and 4t adhered to the siding board 2a are adhered by the adhesive 3 applied in the second adhesive application step (second exterior tile adhesion step). When the second exterior tile bonding step is completed, the process waits until the adhesive 3 applied in the second adhesive applying step is cured (second adhesive curing step), and then, as shown in FIG. Thus, the adhesive 3 is applied on the other siding board 2b, and as shown in FIG. 9, the remaining exterior tiles 4c, 4d, 4g, 4j, 4
k, 4n, 4q, 4r, 4u are adhered.

According to the method for installing the exterior tiles according to the second and third embodiments, the exterior tiles 4c, 4f, 4j, 4g, which are bonded to the joint portions 2c of the one and other siding boards 2a, 2b. In 4m, 4q, and 4t, only the large area indicated by oblique lines in FIG. 9 is bonded via the adhesive 3 and the small area is not bonded with the seam 2c. In the same manner as the exterior tile construction method according to the first embodiment, one and the other siding boards 2a and 2b shrink, the building is deformed by an earthquake, a typhoon, or the like, or is made up of columns, a base (not shown), or the like. Even when the structure undergoes dimensional change or deformation due to repeated wet and dry, the crack C as shown in FIG. 11 does not occur. In particular, the second and third
In the case of the exterior tile bonding step according to the embodiment, since it has the first adhesive application step described above,
In addition to the above-described effects, one of the joints between the exterior tile (the reference numeral is omitted) and the joint between the exterior tiles (the reference numeral is omitted) is near the joint portion 2c of the one and the siding boards 2a and 2b. The color does not differ from the portion distant from the seam portion 2c, and it is possible to have a sense of incongruity.

[0018]

As is clear from the above description of the exterior tile construction method and the exterior tile bonding structure according to each embodiment of the present invention, according to the present invention, the joint between the base plate and the base plate is provided. Since the exterior tile bonded to the part is not bonded at the area where the area is small at the seam,
Even if the base plate shrinks, the building is deformed due to an earthquake, a typhoon, etc., or if the structure consisting of pillars and a base (not shown) undergoes dimensional changes or deformation due to repeated dry and wet, the joint of the base plate Cracks can be effectively prevented from occurring in the exterior tile bonded to the portion. Therefore, anticipating the occurrence of such cracks,
Even after the building is completed, there is no need to save extra exterior tiles for re-placing. In particular, in the case of the exterior tile construction method according to the second invention, the above-described effects are realized by simply applying a sheet or a liquid to the back surface of the exterior tile over the seam portion of one and the other base plates. Since the step of applying the adhesive is not different from the conventional method, it can be easily performed.

According to the third and fourth aspects of the present invention, the first adhesive application step of applying an adhesive to both sides of the base plate around the seam portion outside the base plate is performed. Therefore, the color exposed between the exterior tile and the exterior tile bonded in the vicinity of the seam portion should not be changed at all from the color exposed between the other exterior tile and the exterior tile. Since it is possible, it is possible to make the overall appearance completely uncomfortable.
