Description

[Detailed description of the invention] (a) Industrial application field The present invention is applicable to roof tiles consisting of a tile body made of ceramic or natural slate, and a support member made of plastic or rust-resistant metal, especially for large ceramic tiles. It is suitable for use in a roof tile having a tile body made of tile or an expensive natural slate tile body, and specifically relates to the structure of a receiving member used in a joint portion of a roof tile.

(b) Conventional technology Conventionally, there are various types of roof tiles such as Japanese and Western types, but all of them are relatively small.
Moreover, each tile is partially overlapped on the front, back, left and right sides. Additionally, roof tiles are made of a single piece made of a plastic material such as ceramics.
It is impossible to roof tiles in close contact with adjacent tiles.

(c) Problems that the invention aims to solve For this reason, roof tiles have a complex shape so that they can overlap front to back, left and right, and have large overlapping areas that cover as much as 40% of the total tile area. need. Furthermore, although roofs with a gentle slope are now desired due to Western-style designs of buildings and site efficiency, there is a risk of leaks if roof tiles are laid on a gentle slope, and generally roofs with a slope higher than a specified slope are The roof must be covered with tiles on a steep slope. Therefore, the number of tiles per unit building area (roof projected area) increases, which causes an increase in the weight of the roof, and, together with the increased labor involved in tiling work, causes an increase in the cost of roofing work. It's summery.

(d) Means for solving the problem The purpose of this invention is to eliminate the above-mentioned drawbacks, and the present invention is to provide flexibility to the receiving member made of plastic or the like that is fixed to the body of the tile made of ceramic or the like. In addition, a tongue extending approximately the entire length or width of the tile body is formed, and when the tile is installed, the tongue comes into contact with the back surface of the tile body above the tongue and is bent, forming a gutter-like groove. It is characterized by:

(e) Effect Based on the above-mentioned structure, the flexible tongue of the receiving member, due to its elastic force, seals in close contact with the back surface of the adjacent (side or upper) tile main body, and prevents rainwater from entering from the tile joint. The rainwater that has been blocked from entering is guided through a gutter-like groove and discharged from the back side of the tile.

(F) Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 2, the roof tile 1 includes a large, relatively thin, and generally flat ceramic tile body 2 of a simple shape, a lateral joint receiving member 3 made of durable plastic, and It consists of a vertical joint receiving member 5. As shown in FIG. 1, the tile main body 2 has one side in the horizontal direction bent to have a crank-shaped cross section to form an insertion part 6, and a predetermined number of vertical ribs 7 on the back surface of the main body. has been done. Furthermore,
The insertion portion 6 has a valley groove 9 and an overhanging protrusion 10 with a wide upper end formed on its front side, and two small engagement grooves 11 and 12 extending in the vertical direction on its back side. ing. On the other hand, tile body 2
On the back surface on the other side in the lateral direction, there is formed a protrusion 13 extending in the vertical direction and having a serrated cross section and having a rising surface in the direction of the joint portion C and an inclined surface at the other end. The insertion portion 6 has an overhang-like protrusion 10 and small engagement grooves 11 and 12 have engagement claws 1.
5, 16, and 17 are engaged to fix the horizontal joint receiving member 3. As shown in FIG.
9, and a tongue portion 20 that is flexible and extends over approximately the entire length of the tile main body 2, and furthermore, the upper portion of the fixing portion 19 has a cross section that is easily deformed by pressing force from above. Two mushroom-shaped small protrusions 21, 21 are formed, and the tongue portion 20 consists of two tongue pieces 20a, 20b extending upward.

Further, as shown in Fig. 4, the vertical upper part (butt part) of the tile main body 2 remains a flat surface, and the flat butt part 22 has two small engagement strips on its front and back surfaces, respectively. Grooves 23, 23, 25, 25 are formed. On the other hand, the vertical lower part, that is, the head 26 of the tile main body 2
A water drop 27 is formed on the lower end of the water drop, and a chamfer 29 is formed on the back side of the lower end of the water drop so as not to interfere with the vertical joint receiving member 5. Furthermore, head 2
On the back side of 6, there are two saw-toothed protrusions 30, 30' extending laterally, with the dripping side being the rising surface.
Further, at the rear of the projection 30', a relatively high embankment-like projection 31 whose dripping side is a rising surface is formed laterally. Further, the longitudinal joint receiving member 5 is fixed to the butt portion 22 by engaging the engaging claws 32, 32, 33, 33 in the engaging grooves 23, 25. The receiving member 5 includes a fixed part 34 having engaging claws 32 and 33, and a flexible tongue part 35 extending over substantially the entire width of the tile main body 2. are three tongue pieces 35a, 3 extending upward.
It consists of 5b and 35c.

In addition, in FIG. 2, the receiving member 3 is bent so as to close the upper end of the insertion part 6, and the fixing part 1 is bent.
9' is engaged with and fixed to the upper end portion of the valley groove 9.
Moreover, 36, 36 are needle holes made through the vertical support member 5.

Since the present embodiment has the above-described configuration, as shown in FIG. 1, the roof tiles 1' which are laterally adjacent to each other above the insertion portion 6 are partially overlapped, and the roof tiles are successively covered. At this time, the small protrusions 21, 21 of the horizontal joint receiving member 3 fixed to the insertion part 6 are plastically deformed by the weight of the upper tile 1', and are aligned to fit the back surface of the tile 1'.・As well as being in close contact, the tongue part 20
is bent, and due to its elastic force, the front tongue piece 20a
is in close contact with the top of the sawtooth-like projection 13, and the rear tongue piece 20b is in close contact with the foot of the projection 13. As a result, the receiving member 3 and the back surface of the tile 1' are brought into close contact with each other in a sealed manner, and gutter-like grooves 37a and 37b are formed by the bent tongues 20a and 20b, respectively. Therefore, rain that has entered through the gap C flows downward along the valley groove 9, but normally it rarely overflows the valley groove 9 due to the close contact between the plastically deformed small protrusions 21, 21. Furthermore, during heavy rain such as a typhoon, rainwater that overflows the small protrusions 21, 21, or rainwater that travels down the back side of the tile 1' and exceeds the small protrusions 21 due to surface tension, is removed by the serrated protrusions 13 of the tongue piece 20a. Due to its close contact with the top, it is guided into the gutter-like groove 37a and flows downward. Furthermore, even if rainwater should infiltrate beyond the tongue piece 20a, since the tongue piece 20b is in close contact with the foot of the sawtooth-like projection 13, it will be guided into the gutter-like groove 37b and flowed downward. .

Further, as shown in FIG. 4, roof tiles 1'' vertically adjacent to the upper part of the butt part 22 are partially overlapped and roof tiles are successively covered.At this time, the vertical joint receiving member fixed to the butt part 22 5, the tongue part 35 is bent, and its elastic force causes the front small tongue piece 35a to be placed on the back surface of the droplet 27, the intermediate middle tongue piece 35b to be placed on the top of the sawtooth-like process 30', and the further rear part The large tongue piece 35c comes into close contact with the base of the protrusion 33 and the embankment-like protrusion 31, respectively.Thereby, the receiving member 5 and the back surface of the tile 1'' are in close contact with each other in a sealed manner, and the bent tongue piece 35
gutter-like grooves 39a and 39b are formed by b and 35c. Therefore, rainwater that has entered through the gap D between the drip 27 is first blocked by the small tongue 35a, and furthermore, rainwater that has entered beyond the small tongue 35a is blocked by the middle tongue 35b that comes into close contact with the sawtooth-like protrusion 30'. This prevents the water from climbing upwards, and guides it along the trough-like groove 39a to the lateral ends or to drainage holes formed in the tongue piece 35a at predetermined intervals. Furthermore, in case the middle tongue piece 35
Even if rainwater enters beyond b, it is prevented from rising any further by the large tongue piece 35c, and is guided along the gutter-like groove 39b to the horizontal end or to the drainage hole bored in the middle tongue piece 35b. . In addition, during a typhoon, rainwater tends to flow up the back side of the tiles due to the influence of wind, but the wind cannot blow through due to the close contact between the tongue pieces 35a, 35b, and 35c, and especially the back side of the large tongue piece 35c looks like an embankment. By being in contact with the protrusion 31, the large tongue piece 35c does not warp even in the event of a strong wind, and on the contrary, the wind force causes the tip of the large tongue piece 35c to touch the back side of the tile (the protrusion 3
1) to form a seal, reliably preventing wind from blowing through the saw-toothed protrusions 30, 3.
0' and the tongue pieces 35a, 35b, 35c, these rainwater falls and flows into the gutter-like grooves 39a, 39.
be guided by b.

In addition, in the above-mentioned embodiment, both the horizontal joint receiving member 3 and the vertical joint receiving member 5 are provided in one tile, but by changing the shape of the tile main body 2, only the horizontal joint receiving member 3 or the vertical joint receiving member 3 is provided. Of course, only the receiving member 5 may be provided. Also, as shown by the chain line in Figure 1,
It is also possible to further increase the number of tongue pieces 20c to improve the rainwater blocking effect and to accommodate even more gently sloped roofs. Further, although the horizontal joining receiving member 3 is provided in the insertion part 6 of the tile main body 2, the insertion part 6 is not formed in the tile main body 2, the tile main body 2 is joined without overlapping in the horizontal direction, and the lower part of the joining part is The lateral joint receiving member 3 may be arranged so as to be located at.

Next, other embodiments will be described based on FIGS. 5 to 7.

As shown in FIG. 5, the horizontal joint receiving member 3 according to this embodiment consists of a fixing part 42 having engaging claws 41 and a receiving part 43 extending in the vertical direction. It is fixed at the center of the butt part 22 of the tile main body 2. The tile main body 2 is made of wide, large-sized ceramics, has a substantially flat surface, is joined without overlapping in the horizontal direction, and is roofed in a staggered manner in the vertical direction. Therefore, the receiving part 43 of the receiving member 3 is located below the joint part C of the upper tile main body 2. As shown in FIG. 7, the receiving portion 43 includes a number of flexible tongue pieces 45a, 45b, 45c, 45d, 45e that are symmetrically formed.
It has a tongue portion 45 consisting of, and is formed with a large number of protrusions 46 and 47 extending in the vertical direction. Furthermore, each tongue piece 45a and 45a, 45a and 45b, 45b and 45c, 45c and 45d, 45
Gutter-like grooves 49a and 49 are provided between d and 45e, respectively.
b, 49c, 49d, and 49e are formed and guided to the surface of the tile main body 2, respectively. On the other hand, on the back surface of the tile main body, a large number of sawtooth-like protrusions 50 with rising portions toward the joint C are formed at predetermined intervals, and furthermore, on the outside of the sawtooth-like protrusions 50, larger sawtooth-like protrusions are formed. A protrusion 51 is formed.

Since the present embodiment has the above-described configuration, the tile 1 is roofed so that the joint C is located above the receiving member 3. At this time, each tongue piece 45a of the receiving part 43,
The tongues 45b, 45c, 45d, and 45e are bent as they come into contact with the back surface of the tile main body 2, so that the tips of the tongues are brought into close contact with each other in a sealed manner due to the elastic force. Further, the rising portion of the large protrusion 51 prevents the outermost tongue piece 45e from expanding outward. Therefore, rainwater that has entered from the joint C is sealed by the tongues 45a, 45a, is guided to the gutter-like groove 49a, and is discharged to the surface of the tile main body 2 below, and is further drained from the gutter-like groove 4 during heavy rain or the like.
Even if the tile 9a overflows, it is guided to the gutter-like grooves 49b, 49c, . . . by the successively sealed tongues 45b, 45c, and is discharged to the tile body below.

In addition, in all of the above embodiments, the receiving members 3 and 5 were made of weather-resistant plastic such as vinyl chloride or polyester glass fiber.
Rust-resistant metals such as copper, galvanized plates, resin-plated plates, and stainless steel may be used.Although the tile main body 2 is made of ceramic, it is of course possible to use cement tiles, natural tiles, or asbestos tiles.

(g) Effect of the invention As explained above, according to the invention, the receiving members 3 and 5 have flexible tongue parts 20, 35, and 45.
When the tile is laid, the tongue comes into contact with the back surface of the tile main body 2 above the tongue and bends, forming a gutter-like groove 3.
7, 39, and 49, the tip of the tongue comes into close contact with the back surface of the tile main body in a seal-like manner due to its elastic force, blocking rainwater from entering, and draining it down through the gutter-like groove to prevent rain from leaking. be able to. Furthermore, the tongue portions include tongue pieces 20a..., 35a..., 45a as necessary.
By increasing the number of..., the infiltration blocking effect of rainwater can be easily ensured. Therefore, it is possible to significantly reduce the overlap of roof tiles, reduce the weight of the roof and reduce the cost of roof construction, as well as make the roof slope gentler, allowing for a variety of building designs. It is possible to respond to the need for efficient use of land and the efficient use of land.
