Description

[Detailed description of the invention] "Purpose of the invention" (Field of industrial application) The present invention relates to a novel long tile that can be easily installed.

(Prior Art and Background) FIG. 3 is a partial perspective view showing a state in which a plurality of conventional long tiles 1 are adhered to a base wall surface 5 of a building or the like. The long tile 1 is extruded from cement. The thickness forming element of the elongated tile 1 is a base portion 2 in the shape of a horizontally long strip.
, an intermediate layer section 3 formed on the front side of the base section 2, and a top plate section 4 formed further on the front side of the intermediate layer section 3. The base portion 2 was formed such that an upper edge portion 2a of the base portion 2 protrudes upward from the upper edge portions of the intermediate layer portion 3 and the top plate portion 4. Further, the top plate portion 4 was formed so that its lower edge portion 4a protruded further downward than the lower edge portions of the intermediate layer portion 3 and the base portion 2. Therefore, in a wall using the elongated tiles 1, the upper edge 2a of the base part 2 and the lower edge 4a of the top plate part 4 are connected to the elongated tiles positioned below and above them. ] It had become a structure. Incidentally, the front surface of the top plate portion 4 was glazed and had excellent color and smoothness. Furthermore, a lightening hole 3a having an opening shape of a vertically long round was bored through the intermediate layer portion 3 along the longitudinal direction of the elongated tile 1.

By the way, when the conventional long tiles 1 are installed side by side at the same height,
A joint rod 6 was required to be inserted between the tiles. The joint bar 6 is intended to visually block the base wall surface 5 of a building, etc., and is a strip made of aluminum alloy, stainless steel, or the like, and is drawn into an E-shaped cross section. Band-like gaskets 7, 7 made of rubber or the like are fitted into the joint bar 6 from both sides of the web portion, and the long tiles 1, 1 are connected to each other.
were brought into a butt state with both band-shaped packings 7, 7 interposed therebetween. However, the construction work of the long tiles 1 using the joint rods 6 is troublesome, and there is a drawback that the joint rods 6 and the band-shaped packing 7 need to be repaired according to their deterioration over time, and management and inspection thereof are required. Therefore, there was a strong desire to develop a construction structure that does not use the joint bar 6.

The present invention was developed in view of the above-mentioned circumstances, and in addition to the joining structure at the top and bottom sides, it is possible to adopt the joining structure at both the left and right ends. do not use
The purpose of the present invention is to provide a new long tile (hereinafter referred to as the "proposed tile") that can be easily installed.

``Structure of the invention'' (Means for solving the problem) The gist of the proposed tile is that an intermediate layer is formed on the front side of the horizontally long strip-shaped base, and an intermediate layer is further exposed on the front side of the intermediate layer. A plate part is formed,
The upper edge of the base part is formed to project upwardly from the upper edges of the intermediate layer part and the top plate part, and the lower edge part of the top plate part is formed below the lower edge parts of the middle layer part and the base part. In the elongated tile, a lightening hole having a vertically elongated round opening shape is formed in the intermediate layer portion and extends through the base portion in the longitudinal direction of the base portion. The lightening hole provided is formed so that the inner surface of the hole near the base portion is flush with the front surface of the base portion.

(Function) Even if the top plate part and the middle layer part are removed from the front side of the right or left end part of the proposed tile, leaving only the base part, the front side of the remaining base part and the middle part are removed. There is no difference in level between the lightweight hole drilled in the layer and the inner surface of the hole near the base. That is, the front surface of the remaining base portion is a flat surface, and there is no problem in appearance.
Therefore, it has become possible to adopt a converging structure at both the left and right ends. Therefore, the joint rods conventionally used to block the visual appearance of the underlying walls of buildings, etc., are no longer necessary when the tiles of the present invention are attached. In addition, in conventional long tiles, the lightweight holes drilled in the intermediate layer were drilled extending into the flesh area forming the base section, as described below, so the above-mentioned joint structure was not possible. was virtually impossible to collect.

(Example) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is a side sectional view showing the proposed tile. First, the general structure of the main tile will be explained.
The proposed tile has a base part 8, an intermediate layer part 9, and a top plate part 10 integrally formed in the thickness direction from the back side (left side in the figure) to the front side (right side in the figure). The names of section 8, intermediate layer section 9, and top plate section 10 are given for convenience of explanation, and there is no clear division in the actual structure.) The base portion 8 has an upper edge portion 8a that is connected to the intermediate layer portion 9.
Upper edge portion 9a and upper edge portion 10a of top plate portion 10
It is formed to protrude upwards. Also,
The top plate portion 10 is formed so that its lower edge portion 10b extends further downward than the lower edge portion 9b of the intermediate layer portion 9 and the lower edge portion 8b of the base portion 8. Therefore, the proposed tile has the upper edge part 8a of the base part 8 and the lower edge part 10b of the top plate part 10, so that it has the same effect as the wall using the conventional long tile 1 (see FIG. 3). , is equipped with a joint structure for long tiles positioned at lower and upper levels. Further, the intermediate layer portion 9 has three lightweight holes 12, 12, 12 each having a vertically long round opening shape.
is bored through the base portion 8 along the longitudinal direction.

The most important structure of the proposed tile is that in the lightweight hole 12 drilled in the intermediate layer section 9, the inner surface 12a of the hole, which is closer to the base section 8, is flush with the front surface of the base section 8. It is at the point where it is formed. Since the proposed tile is formed in this manner, it is possible to adopt not only the upper and lower joining structure, but also the left and right joining structure, as shown in FIG. 2. The proposed tile shown in FIG. 2 has a top plate part 10 and an intermediate layer part 9 (see FIG. 1) that are arranged so that only the base part 8 remains from the front side at the left end.
has been deleted. Further, at the right end, the base portion 8 is removed from the back side, and part or all of the intermediate layer portion 9 is removed as necessary. When performing these cutting operations on the green material immediately after extrusion molding (before hardening or firing), it can be performed by a simple cutting operation using piano wire (not shown) or the like. Further, after hardening or firing, it can be performed using a grinder, a diamond saw, or the like.

The proposed tile satisfies the following three restrictions regarding the shape at the same time when adopting the above-mentioned important structure. First, since the long tiles are formed by extrusion molding, their cross-sectional shape must take into account the load distribution during molding. That is, centering on the intermediate layer section 9, the top plate section 10 and the base section 8 need to have the same thickness. Also, the second
As a limitation, since the weight-reducing holes 12 formed in the intermediate layer portion 9 are intended to reduce the weight of the entire tile, the hole width cannot be made unnecessarily small. Furthermore, the third limitation is that the base part 8 is screwed to the base wall surface of a building or the like through screw holes 13 drilled in the upper edge part 8a that projects upward. Requires wall thickness. These are the three above.

Incidentally, the various dimensional relationships of the conventional long tiles are also indicated by two-dot chain lines at approximately the center height position in FIG. 1 showing the proposed tile. In conventional long tiles, the wall thickness occupied by the intermediate layer portion 3 is increased to increase the amount of lightening made by the lightweight holes 3a. Also,
The back surface of the base portion 2 is cut to form a sole 2b with the minimum height necessary for anchoring, thereby making the thickness of the base portion 2 and the thickness of the top plate portion 4 smaller. I tried to make them equal. Therefore, the middle layer 3
The inner surface of the lightening hole 3a drilled in the hole near the base portion 2 was not flush with the front surface of the base portion 2. Therefore, if the top plate part 4 and the middle layer part 3 are cut off from the front side of one end of such a conventional long tile, there will be a lightweight hole in the front of the base part 2. It is clear that a step is formed in the area adjacent to 3a. That is, even if the conventional long tiles were pasted together as shown in FIG. 2, a joint material was required to visually block the stepped portion formed by the lightening hole 3a.

In the proposed tile, the height h of the sole 11 formed on the back surface of the base portion 8 is made higher than that of the conventional tile, and the lightweight hole 12 is formed through the intermediate layer portion 9.
The hole width has been made slightly narrower. In this way, the wall thickness t of the portion of the base portion 8 excluding the sole 12
can be maintained to be equal to the thickness of the top plate portion 10. In addition, by increasing the amount of lightening in the base portion 8 for forming the sole 11,
It is also possible to reduce the weight of the entire tile. Furthermore, the upper edge portion 8a of the base portion 8 can have a wall thickness that can withstand screwing. In this way, the proposed tile has three restrictions regarding the shape of long tiles:
All are satisfied.

(Study of Alternative Embodiments) The tile of the present invention is not limited to the fact that it already has a convergence structure at both left and right ends thereof. Therefore, when installing the tiles, a joint bar can be used as in the case of conventional long tiles. Further, the tiles of the present invention are not limited to those made of cement, but may be made of ceramics. By making the base portion 8 from ceramics, the horizontal length of the base portion 8 can be approximately 1800 mm. In this way, the configuration and shape of the proposed tile are as follows:
It can be modified as appropriate depending on the mode of implementation.

"Effects of the Invention" As is clear from the above explanation, according to the long tile according to the present invention, in addition to the joining structure on the top and bottom sides, it is possible to adopt the joining structure on both the left and right ends. Moreover, the joining structure of both the left and right ends can be easily performed even during the manufacturing process or at the construction site. Furthermore, by employing such a structure in which both the left and right ends meet, the joint bar that was conventionally required becomes unnecessary. Therefore, from the construction work when attaching the proposed tiles, not only the work related to the installation of joint bars can be completely omitted, but also the repair and management of the joint bars or band-shaped packing due to aging deterioration, Inspections, etc. are no longer necessary. Moreover, when the proposed tiles are adhered without using a joint bar, there are many excellent advantages such as the ability to adjust the width of the joints formed between each tile.
