[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a main wall for tile construction made of concrete or synthetic resin, which is used by attaching tiles to the surface.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, a concrete wall on which a tile excellent in decorativeness and corrosion resistance is attached has been widely used as an outer wall of a building or the like.

In order to attach the tiles to the concrete wall surface, it is general to apply a base mortar to the entire surface of the wall surface, and then to the surface with a mortar, an organic adhesive or the like.

However, in recent years, the tile wall thus mounted is frequently accidentally separated from the base mortar and dropped, and a drastic measure for preventing the fall is awaited.

As an example of such a measure, Japanese Utility Model Laid-Open No. 3-98255 proposes a form plate in which a dovetail member having an elastic body for forming a plurality of dovetail grooves parallel to a concrete forming surface is provided in a protruding manner. Has been done.

This formwork plate is used in the same manner as an ordinary concrete formwork, and as shown in the sectional view of FIG. 6, on the surface of the hardened main wall 20, there are dovetail grooves corresponding to the dovetail members of the formwork plate. 21 is formed. For this reason, the base mortar applied to the surface of the main wall 20 during tile application enters into the dovetail groove 21 and hardens, increasing the bonding force between the base mortar and the main wall, and after the installation, the base mortar is removed. It can effectively prevent peeling and falling from the body.

[0007]

[Problems to be solved by the device]

 However, the dovetail groove 21 of the main wall 20 formed by this form plate is such that its shape expands inward from the surface of the wall body, and the lower surface side 21 a of the dovetail groove 21 is inclined downward. It has a tapered surface.

On the other hand, since the base mortar for mounting tiles is applied from the bottom to the top, the base mortar applied to the front surface of the main wall 20 may not be sufficiently filled in the groove 21. However, there is a problem that a sufficient bonding force between the main wall 20 and the base mortar cannot be expected.

The present invention solves the above-mentioned conventional problems, in which the lower mortar provided on the front surface of the main wall is completely filled in the uneven portion formed on the main wall, and The purpose is to increase the bonding strength with the base mortar and eliminate peeling after construction.

[0010]

[Means for Solving the Problems]

 The main wall for tile construction of the present invention is a main wall for tile construction in which a concave fitting portion for preventing peeling is provided on the surface and a tile is attached after applying mortar or the like to the concave fitting portion. The concave fitting portion is independently formed, and the lower surface side of the concave fitting portion is tapered upward.

Here, instead of the concave portion, a convex portion may be formed, and the upper surface side of the convex portion may be formed in an upward taper shape.

Further, it is also possible to adopt a two-step structure in which a concave portion or a convex portion having a smaller diameter is further provided at the tip of the concave portion or the convex portion. An uneven shape can also be formed.

[0013]

[Action]

 A mortar for laying tiles to be laminated on the surface by forming concave portions or convex portions formed on the main wall independently of each other, and by tapering the lower surface side of the concave portion or the upper surface side of the convex portion upward. A part of is filled in the concave portion or the convex portion without gap along the upward tapered surface. Therefore, the outer peripheral surface of the hardened base mortar and the concave portion or the convex portion are brought into complete contact with each other. In addition, the surface of the main body wall can be roughly formed by the fine particles adhered to the mold.

【Example】

 FIG. 1 is a sectional view showing a tile installation state, FIG. 2 is a perspective view showing an embodiment of a main wall for tile application of the present invention, and FIG. 3 is a sectional view taken along the line AA of FIG.

In FIG. 1, reference numeral 1 is a main wall for tile construction made of concrete or the like, and a concave portion 2 as a fitting portion for preventing peeling is formed on the surface thereof. The concave portion 2 has a truncated cone shape that is contracted toward the inside of the wall, and the center of the upper bottom (inner side) is displaced upward with respect to the center of the lower bottom (main body wall surface side). With such a shape, a tapered surface 2a having an upward slope from the surface of the main wall toward the back is formed in a region of the lower half of the peripheral surface of the recess 2. Here, 4 is a base mortar, 5 is a tile, and 6 is a pressure bonding mortar.

Here, the recess 2 can be determined depending on the thickness of the base mortar 4 and the size of the tile 5, but generally, the diameter is 10 to 15 mm and the depth is about 5 to 10 mm. The joining force between the base mortar 4 and the main wall 1 can be improved without lowering the strength of the main wall 1.

In this way, by making the lower surface side of the concave portion 2 an upward inclined surface, when the base mortar 4 for tiling is applied to the surface, it is slid with a trowel from the bottom to the top. Therefore, the mortar quickly advances into the recess along the inclination of the tapered surface 2a. Therefore, it is possible to reliably fill the concave portion 2 with the adhesive mortar, and it is possible to perform the construction without the generation of solid cavities. Therefore, the outer peripheral surface of the base mortar hardened in the recesses 2 is constrained by the entire inner peripheral wall of the recesses 2, and it is possible to effectively prevent peeling of the base mortar after construction.

Further, in the main wall shown in FIG. 2, the recesses are formed at substantially the same pitch in the vertical and horizontal directions. However, instead of such an arrangement, the recesses 2 are arranged in a zigzag pattern, or a plurality of recesses are formed. It is also possible to disperse one group of the concave portions 2 and divide it into a plurality of groups.

Further, the shape of the concave portion 2 is not limited to the above-mentioned embodiment, but may be any shape as long as the lower surface side is inclined upward so as to easily fill the base mortar. A specific example thereof is shown in FIG. Show.

In FIG. 4A, the upper surface 2b of the recess 2 is tilted upward substantially parallel to the lower tapered surface 2a. With such a shape, the base mortar 2 can be filled and hardened in the expanded portion of the upper portion of the recess 2 and the binding force between the main wall 1 and the base mortar 2 can be improved.

The concave portion 2 of FIG. 4B is provided with a small-diameter concave portion 2d having a two-step structure in parallel with the tapered surface 2a so as to be coaxial with the upper bottom at the tip of the base portion 2c having the tapered surface 2a. It is an example. In this example, in addition to the joining force of the concave portion 2 and the joining force of the small concave portion 2d, the joining force between the base mortar and the main wall can be further improved.

FIG. 4C shows an example in which the concave portion 2 has a conical shape. Even with this shape, when the ground mortar is pressed against the surface of the main wall to apply it, the mortar is filled along the inner peripheral surface of the recess into the inner part without any gap.

In the above embodiment, the concave portion 2 is formed in the main wall 1, but the present invention is not limited to this, and the convex portion 3 may be formed on the surface of the main wall 1 as shown in FIG. .. At that time, the upper surface side of the convex portion 3 has a shape having an upward tapered surface 3a. Further, a small-diameter convex portion 3b may be formed in parallel with the tapered surface 3a. Further, if necessary, the concave portion 2 and the convex portion 3 may be mixed together in the vertical and horizontal directions to form a main wall.

FIG. 6 is a cross-sectional view for explaining the method for manufacturing the main wall for tile construction described with reference to FIGS. 2 and 3.

In the figure, 10 and 11 are mold members similar to the conventional one, and a temporary frame member 12 for forming a recess is attached to the inner surface of the mold 11 on which the tiles are attached. As shown in the perspective view of FIG. 7, the temporary frame member 12 has protrusions 12b made of an elastic body such as rubber or soft resin corresponding to the above-mentioned recesses 2 at equal intervals over the entire surface of the sheet 12a. I did it. In this state, a curable fluid, such as raw concrete or synthetic resin, is placed in the molds 10 and 11. Then, after the concrete or the like is hardened, when the mold is disassembled, the concave portion 2 having a predetermined shape is formed on the surface of the main wall 1. It should be noted that the main wall can be similarly formed by forming the projection 12b into a shape corresponding to each recess shown in FIG.

Since the protrusion 12b is formed of a deformable elastic body, the protrusion 12b shrinks at the time of demolding even if the protrusion 12b has a concave shape as shown in FIGS. 4 (a) and 4 (b). It becomes possible to deform and easily remove it without destroying the shape of the recess 2.

In addition, an adhesive such as an acrylic emulsion system is sprayed on the entire surface of the temporary frame member 12 or at least the surface of the projection 12b in advance, and sand having a diameter of 2.5 to 5 mm is sprinkled on the surface. Then, by adhering it to the temporary frame member 12, smaller concave and convex portions are formed on the surface of the large concave portion or convex portion. Therefore, the main wall surface molded by this has a rough surface with small unevenness formed by sand particles on the large uneven surface, and it is possible to further increase the bonding force with the underlying mortar applied to the surface. ..

It should be noted that the surface of the main wall for tile construction thus formed is subjected to the underlying mortar as described above and aged for a predetermined period of time, and then the surface of the tile mortar, an organic adhesive or the like is applied to the surface. The tiles are attached to complete the product.

[0029]

[Effect of the device]

 As explained above, the main wall for tile construction of the present invention has the concave portions or convex portions for preventing peeling formed independently of each other, and the lower surface side of the concave portions or the upper surface side of the convex portions is tapered upward. I am trying. For this reason, a part of the tiling base mortar to be laminated on the surface of the main wall is filled in these recesses or protrusions without any gap, and the hardened base mortar is constrained by the entire peripheral wall of the concavo-convex part. Become. Therefore, the joining force between the main wall and the underlying mortar can be increased, and peeling after construction can be eliminated.

Further, the shape of the concave portion or the convex portion has a two-step structure, and the surface of the concave portion or the convex portion is formed in a fine uneven shape, whereby the bonding force can be further strengthened.
