Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tile base substrate for a tile wall surface that adheres and fixes a tile to the surface of a base substrate.

[0002]

[Prior art]

 Conventionally, as a method of applying tiles on the exterior substrate, a crimping method is used in which the substrate is undercoated, the intermediate coating is applied, the mortar is applied to almost the same thickness, and then the tile is pressed and pasted onto it. Although it is generally known, it required a high level of construction technology and a long time by skilled craftsmen, such as tile allocation when cementing tiles with cement mortar, and joint treatment after that.

In order to solve the problem of such wet method tile construction, a plurality of ridges are provided in parallel on the surface of the base substrate, and a plurality of plate-shaped decorative blocks are arranged between the ridges. A wall material that has been fitted and attached has been devised. (Refer to Actual Kaihei 4-2825 bulletin)

[0006] Thus, by forming the ridges on the substrate surface, tiles can be easily allocated. However, in this tiling panel, the tiles form the joints by adhesively fixing the tiles using an adhesive according to the signs assigned by the tiles. The molding accuracy of the ridges on the base plate is poor, and a gap is created between the tiles and the ridges, which is not desirable in terms of design.Finally, a joint mortar is put into the joints to make it flat with a trowel. Construction was required and was still unsatisfactory.

[0005]

[Problems to be solved by the device]

 If it is necessary to finally put cement mortar into the joints, the present inventor uses a base substrate having ridges formed on the surface as described in Japanese Utility Model Laid-Open No. 4-2825 and uses ridges. After applying cement mortar to parts other than the above, we investigated to provide a method that allows joints to be formed at the same time when the tiles are pressure-bonded.As a result, we adjusted the level to the tip of the ridge and applied it to the part other than the ridge. By crimping the tile onto the cement mortar that has been crushed and swinging this tile up, down, left and right, the cement mortar under the tile is extruded and rises on the lengthwise and widthwise edges of the tile. An attempt was made to form joints with this cement mortar that had been coated.

[0006] However, most of the extruded cement mortar is extruded to the edges of the tile in the length direction, and it is difficult to extrude in the width direction, that is, the swelling of the cement mortar on the surface of the part where the ridge is formed. Since it was too small, it was still necessary to insert cement mortar into the joints of the ridges.

This phenomenon is caused by the fact that in a tile having a back surface with a “back”, convex stripes of the “back” are formed in parallel with the length direction of the tile, and are further extended toward the edge in the length direction. The flow of cement mortar was promoted, and almost no extrusion of cement mortar in the width direction occurred.

[0008]

[Means for Solving the Problems]

 The present invention aims to provide a tile base substrate which can easily solve the above-mentioned problems of the prior art and can complete the crimping and fixing of tiles and the joint construction in one operation. It was completed as a result of the device.

That is, according to the present invention, a plurality of ridges 2 are provided in parallel on the surface of the substrate 1, and one of the ridges 2 in the width direction is formed to rise vertically while the other rises in an inclined manner. It is a tile base substrate.

[0010]

[Action]

 The tile base substrate of the present invention is provided by inclining one of the rising portions of the ridges 2 provided parallel to the surface, so that the cement mortar 7 is applied even near the tip of the ridges 2 in the tile construction. Then, the tiles 8 are then crimped between the ridges 2 so that not only the edges of the tiles in the length direction but also the cement mortar 7 from between the tiles 8 and the sloped rising portions 2b of the ridges 2 are pressed. Is pushed out and rises up on the ridge 2, and all the joints 3 can be constructed by flattening this raised portion with a trowel.

Further, in the flat surface portion 6 between the ridges 2, the groove 6a is formed in the inclined rising portion 2b of the ridge 2 so that the tile 8 can be pressed. The flow of the mortar 7 onto the ridges 2 is made smoother.

[0012]

【Example】

 The tile base substrate of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of a tile base substrate 1 of the present invention. Further, FIG. 2 shows a cross section taken along the line AA of FIG. In the tile base substrate 1 of the present invention, a plurality of ridges 2 are provided in parallel on the surface thereof, and the ridges 2 have vertical rising portions 2a on one side in the width direction that rise vertically and the other rising portions 2b on the other side. It is formed in a shape that rises at an obtuse angle.

Further, the opposite side edges of the tile base substrate 1 are subjected to actual machining as shown by the lower solid 4 and the upper solid 5 to connect the tile base substrates 1 when fixing the tile base substrate 1 to the base surface. Is done.

The actual processing is not limited to the phase-determining processing, and the actual processing or the like may be used. The tile base substrate of the present invention can be obtained by extrusion molding of a kneaded material containing cement as a main component, pressing with a molding board, pouring into a mold, or the like.

The tile base substrate of the present invention can easily perform tile allocation by providing the ridges 2 on the surface, and the sloped rising portion 2b on one side in the width direction of the ridges 2 has an obtuse angle. By being formed with an inclination, a level is applied to the vicinity of the tip of the ridge 2 to apply cement mortar, and the cement mortar 7 and the tile 8 are pressure-bonded to each other, and the cement mortar 7 that rises up causes the joint 3 to rise. Sufficient cement mortar 7 is secured to form it.

Further, the cement mortar is extruded also on the lengthwise edges of the tiles, and the cement mortar sufficient to form a joint between adjacent tiles rises.

Further, as shown in the sectional view of the base substrate of FIG. 3, in the plane portion 6 between the ridges 2, the ridges 2 are formed at the obtusely inclined rising portions of the ridges 2. By forming the concave groove 6a in parallel, the flow path of cement mortar when the tile is pressure-bonded on the applied cement mortar is secured, and the protrusion on the convex stripe 2 is further favorably performed. .

The shape of the groove 6a formed at this time may be a concave lens groove 6a having a curved surface as shown in FIG. 3 or a groove 6 hollowed in a rectangular parallelepiped shape. good.

However, in consideration of the fluidity of the cement mortar when the tile 8 is pressure-bonded, it is preferable that the concave mortar is formed because the fluidity of the cement mortar is better.

A method of constructing the wall surface of the tile 8 using the tile base substrate of the present invention will be described below. First, after the tile base substrate 1 is connected and fixed to the exterior base surface by nailing or the like, cement mortar 7 is applied on the tile base substrate 1, and the level is adjusted to the tip surface of the ridge 2 and the surface is troweled. To flatten. In this state, the ridges 2 exposed on the surface of the cement mortar 7 allow the allocation position of the tiles 8 to be confirmed.

Next, the tile 8 is pressure-bonded before the cement mortar 7 is hardened. The cement mortar 7 applied to the lower surface of the tile 8 by the pressure-bonding of the tile 8 has the lengthwise edges and the width of the tile 8. It flows out from the edge of the direction and rises.

FIG. 4 is a cross-sectional view of this state cut in the vertical direction (tile width direction) on the construction surface. With the lower surface of the tile 8 in contact with the vertically rising portion of the ridge 2, the upper portion of the tile is crimped into the cement mortar 7 with the contact portion serving as a fulcrum so that only the volume of the embedded tile 8 is cemented. The mortar 7 bulges on the ridge 2 through the concave groove 6a formed in the plane portion and the inclined rising portion 2b formed by sloping at an obtuse angle.

In the present invention, one side (lower side) of the ridge 2 is an inclined rising portion 2b which is inclined at an obtuse angle, so that the applied cement mortar can be lifted on the ridge 2 without applying a great amount of pressure. Becomes

Generally, in a horizontally long rectangular tile, a backside is provided with a flat dovetail in the longitudinal direction, and this backstep enhances the adhesive strength of the tile 8 after the cement mortar 7 is hardened and is removed. Prevent peeling.

When a tile in which such a tail is formed in the lengthwise direction is used and the tile 8 is pressure-bonded on the cement mortar 7 while rocking, the cement mortar on the lower surface of the tile becomes a groove of the tail in the tile. Along with the movement, the cement mortar easily flows out to the edges in the length direction, and it is difficult to flow out to the edges in the width direction.

However, by forming the concave groove 6 as in the tile base substrate of the present invention, the cement mortar 7 is also pushed out to the widthwise end side of the tile 8 and rises above the convex stripe 2. It is a thing.

In this way, the cement mortar 7 on the widthwise end side of the tile 8 that rises from between the tile 8 and the ridge 2, and the tile 8 that rises from between the tile 8 and the tile 8 that is laterally adjacent to the tile 8. The joint portion 3 is formed by flattening the cement mortar 7 on the lengthwise side of the with a trowel. FIG. 5 shows a state in which the joint portion is formed using the base substrate 1 in which the groove 6a is formed. FIG. 6 shows a state in which a joint portion is formed using a base substrate in which the groove groove 6a is not formed.

Further, in the tile base substrate of the present invention, according to the allocation of tiles, the ridges having the small ridges in the direction orthogonal to the ridges 2 formed on the surface are changed from the ridges 2 to the ridges 2. It can be provided over or without. By providing such ridges, the positions in the length direction and the width direction of the tile are clarified, and the time required for the tile pressure bonding is further shortened.

[0029]

[Effect of device]

 The tile base substrate of the present invention is formed so that the rising portion of one side in the width direction of the ridge 2 provided parallel to the surface is inclined and rises, so that the cement mortar 7 is applied to the ridge 2 surface. Next, the tiles 8 are pressed between the ridges 2 to press the cement mortar 7 not only between the tile edges in the length direction but also between the tiles 8 and the ridges 2 and the width of the tiles. It will rise above the ridge 2 on the edge of the direction.

It is possible to construct joints simply by flattening this raised portion with a trowel, which eliminates the need to newly insert cement mortar into the joints and reduces the time required for construction. It can be significantly shortened.

Further, in the flat portion 6 between the ridges 2, the groove 6a is formed in the slanted rising portion 2b of the ridge 2 so that the tile 8 can be pressure-bonded. The outflow of the mortar 7 to the end portion in the width direction is made smoother.
