BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall tile assembly in which an appropriate number of minimum unit outer wall tiles attached to a wall surface of a structure are gathered together and integrally connected.

[0002]

2. Description of the Related Art Generally, the above-mentioned aggregate of outer wall tiles has been integrated by attaching a mount having a shape substantially the same as that of the aggregate to the surface of each outer wall tile. Then, after the outer wall tiles were attached to the wall surface in aggregate, the mount was peeled from the surface of the outer wall tiles. However, such a method has a drawback that the workability is extremely poor because it takes time and effort to remove the mount. Therefore, a technique of attaching a small piece of connecting paper to the back surface of the outer wall tile to form an aggregate is disclosed in, for example, Jitsuko Sho 55.
No. 25064. According to this technique, since the connecting paper piece is buried in the mortar in the state where the outer wall tile is attached to the wall surface of the structure, the work of removing the mount as described above is unnecessary and the workability is improved. . Then, as disclosed in Japanese Utility Model Publication No. 55-25064, the connecting paper piece attached to the abutting portion of the four outer wall tiles has a shape in which a circular hole is provided at the center of a square,
The circular holes are arranged so as to match the abutting portions of the four outer wall tiles.

[0003]

Recently, with the deterioration of structures, the peeling accident of outer wall tiles has become a problem. In order to prevent this peeling accident, the current outer wall tile is formed with a dovetail-shaped engaging groove on the back surface so that the mortar can be engaged in the engaging groove. Since the peeling resistance of the outer wall tile increases in proportion to the number of engaging grooves, it is preferable to provide as many engaging grooves as possible. However, on the other hand, if the number of engaging grooves is increased, the length from the engaging groove to the side edge of the outer wall tile is shortened, so that one side of the connecting paper piece must be shortened. Then, the joint surface between the connecting paper piece and the outer wall tile becomes small and the adhesive force is insufficient. As a result, the outer wall tile cannot be firmly connected, and the assembly collapses before or during the work.

The present invention was made in the light of the above problems, and its purpose is to ensure the function of preventing the engagement groove from peeling off and to prevent the connecting paper piece from being removed in the above-mentioned aggregate of outer wall tiles. It is to harmonize the contradictory technical issues of securing adhesive strength.

[0005]

In order to achieve the above object, the present invention provides an assembly 4 of outer wall tiles 1 having the following constitutional requirements (a) to (d). is there.
(A) Engagement grooves 2 are formed on the back surface of the outer wall tile 1. (B) The connecting paper piece 3 includes three or more outer wall tiles 1.
And the engaging groove 2 of the outer wall tile 1.
And upper and lower elongated strips 3a substantially parallel to each other and left and right joint pieces 3b connecting the elongated strips 3a. (C) Connecting paper piece 3
The strips 3a each have a width substantially equal to or less than the length from the engaging groove 2 of the outer wall tile 1 to the side edge thereof, and the length is provided between the outer wall tiles 1 arranged side by side. The adhesive area is set so that it can be connected and held. (D) The joint piece 3b of the connecting paper piece 3 has a length substantially equal to the interval S between the outer wall tiles 1 and connects the vertically arranged outer wall tiles 1 to each other.

[0006]

In order to provide the outer wall tile 1 with as many engaging grooves 2 as possible, it is necessary to make the connecting paper piece 3 small. However, the sticking force is reduced accordingly.
This can be supplemented by laterally extending a along the engaging groove 2. In addition, since the width of the elongated strip 3a of the connecting paper piece 3 is set to be substantially equal to or less than the length from the engaging groove 2 of the outer wall tile 1 to the side edge thereof, the connecting paper piece 3 is formed in the engaging groove 2 of the connecting paper piece 3. It does not protrude inside. Therefore, the mortar 5 is firmly bitten into the engaging concave groove 2, so that the peeling prevention function is ensured.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a back view showing an aggregate of outer wall tiles, and FIG. 2 is a vertical cross-sectional view of a main part showing a state where the outer wall tiles are attached to the wall surface.

The outer wall tile 1 is a ceramic plate having a size of 95 mm × 45 mm, and three dovetail-shaped engaging grooves 2 are formed in parallel on the back surface in the longitudinal direction.

The connecting paper piece 3 for connecting the outer wall tiles 1 is made of a paper having a certain degree of strength, and an adhesive is applied to the entire surface of the side facing the outer wall tiles 1. The connecting paper piece 3 is
It is composed of a pair of upper and lower elongated strips 3a that are substantially parallel to the engaging groove 2 of the outer wall tile 1, and a pair of left and right joint pieces 3b that connect the elongated strips 3a. The elongated strip 3a of the connecting paper piece 3 is
The width is substantially equal to the length from the engaging groove 2 of the outer wall tile 1 to the side edge. Further, the joint piece 3b of the connecting paper piece 3 is
The length is set to be substantially the same as the interval S between the outer wall tiles 1 in the aggregate 4 described later. And connecting paper piece 3
As shown in FIG. 1, the outer wall tile 1 is elongated horizontally.
By increasing the contact area with, the adhesive force is strengthened.

An assembly 4 is formed by combining a plurality of the outer wall tiles 1 and the connecting paper pieces 3 described above. That is, the assembly 4 is a collection of 3 × 6 = 18 outer wall tiles 1 and mainly integrates the abutting portions of the outer wall tiles 1 with the connecting paper piece 3, and has one side of about 30 cm. It has a roughly square shape. The outer wall tiles 1 are arranged with an interval S of about 5 mm between adjacent ones. The connecting paper piece 3 is composed of the four outer wall tiles 1 as described above.
The outer wall tiles 1 are attached to the butted portions of the outer wall tiles 1 and 2 and are joined to each other by the upper and lower elongated strips 3a.
The vertical tiles for outer walls 1 are connected with each other. The portions other than the butted portions of the four outer wall tiles 1 are connected by the elongated strip-shaped connecting paper pieces 30 as shown in FIG.

The aggregate 4 thus formed is attached to the wall surface of the structure as shown in FIG. 2, and the space S between the outer wall tiles 1 is filled with the mortar 5. Since the connecting paper piece 3 is buried by the mortar 5, it cannot be seen from the outside.

Although the embodiment has been described above, of course, the present invention is not limited to this. For example, in the embodiment, the case where the connecting paper piece 3 is bridged over the four outer wall tiles 1 has been described, but it is also applicable to a case where the outer wall tiles 1 on the upper and lower stages are laterally displaced as shown in FIG. . In this case, the connecting paper piece 3 is laid over the three outer wall tiles 1.

Further, the shape of the connecting paper piece 3 does not need to project both ends of the elongated strip 3a to the outside of the joint piece 3b as shown in FIGS. 1 and 3, and is an elongated rectangular ring shape as shown in FIG. May be.

[0014]

As described above, the aggregate of outer wall tiles of the present invention can be attached to the outer wall tile provided with the engaging groove by a sufficient attachment force by extending the elongated strip laterally. It can be worn and there is no risk that the aggregate will collapse before or during work. Moreover, since the width of the elongated strip is substantially equal to or less than the length from the engaging groove to the side edge of the outer wall tile, the connecting paper piece does not protrude into the engaging groove.
Therefore, the mortar is firmly bitten into the engagement groove, so that the peeling prevention function is ensured.
