[0003]

When the roof structure is a dormitory, it is not possible to form ventilation holes in the wall of the attic, and there is a problem in ventilation at the top only with ventilation holes in the eaves. However, when the technical standards of the housing covered by the GHLC loan system were revised from October 1, 1998, and an intake hole is provided on the back of the eaves and an exhaust hole using an exhaust stack or other equipment is provided, The ratio of the effective area to the ceiling area is 1/900 or more, the exhaust holes are provided at the top of the attic as much as possible, and the ratio of the effective area of the exhaust holes to the ceiling area is 1/600 or more. The rule that the thing has been established, and the number of dormitories is increasing in order to suppress the construction cost. Therefore, there is a demand for a ventilated roof structure that is inexpensive, has excellent workability, and meets the above-mentioned technical standards in response to these regulations and trends of the times. In view of those circumstances, the present invention was developed for the purpose of providing a ventilation ridge roof tile which is excellent in ventilation and workability and is inexpensive.

[0004]

The present invention has taken the following technical means in order to solve the problems and achieve the objects.

A main plate portion, a ventilation core, a side wall and a windbreak member are provided. The main plate portion has a pair of elongated main plates with a bendable portion at the center of the parallel width, and the left and right main plates have a non-slip top. The ridges are erected along the length, and the ventilation cores are arranged along the length at the lower surface outer edge portions of the left and right main plates, and the ventilation core has a plurality of lateral ventilation holes arranged in parallel in the longitudinal direction of the main plate. The windbreaker is formed in a substantially L-shaped cross section with a substrate and a front plate perpendicular to the substrate, and the front plate is opposed to the front surface of the ventilation hole of each ventilation core at an appropriate interval so that the substrate is the ventilation core. A ventilation ridge tile rail fixed to a lower surface, the side wall body being made of an elastic square member, and being arranged and fixed in contact with both longitudinal end surfaces of the ventilation core which are the lower surfaces of both longitudinal end portions of the main plate.

The bendable portion of the main plate can be formed of a soft resin body integrally connected to the left and right main plates.

The side wall body may be formed of a closed cell resin molded body.

[0009]

The present invention constructed as described above has the following actions.

When a ventilation gap having a width of about 2 cm is formed on the roof between the left and right end plates facing each other on the rooftop, and when ventilating the attic, this ventilation ridge roof tile is closed so as to close the ventilation gap from above. Apply the crosspiece. The hot air in the attic enters through the ventilation gap between the opposing left and right ventilation cores and is exhausted to the space under the roof tile through the ventilation holes in the left and right ventilation cores.

The bendable part in the parallel middle part of the left and right main plates is
Easy to bend when bending the left and right main plates according to the roof slope.

The side wall bodies at both longitudinal ends of the ventilation core close the ventilation gaps at both ends in the longitudinal direction of the ridge, and close the joints when connecting a plurality of short ventilation ridge tiles in series. Further, the left and right main plates can be easily bent when facing the roof slope at the facing portions.

Since the ventilation core formed by extrusion molding so as to penetrate the ventilation hole in the front and back is manufactured by cutting the front and rear intervals to be short, it is easy to manufacture even if the number of ventilation holes is large, and the strength is sufficient. It is possible to increase the amount of ventilation while keeping it.

Even if rainwater enters through the gaps in the roof tiles due to strong wind and rain, rainwater passes through the ventilation holes toward the back of the hut from the ventilation gaps. Leakage is prevented.

The non-slip ridges 8,
A pair of fitting groove lines 9, 9 into which the height adjuster 10 is fitted is formed at the upper left and right upper edge portions of 8 along the longitudinal direction. Since the length of the main plate portion 2 is extruded, it can be made long, but since it is a member used on the roof, it is sold at 1200
It is set to about millimeters.

In FIGS. 1 and 2, a plurality of partition walls 3C having a height of about 10 mm are arranged at a constant pitch between an upper plate 3A having a width of about 40 mm and a lower plate 3B having a width of about 30 mm. Thus, a plurality of ventilation holes 11 ... Are formed. Although the length is set to be the same as the length of the main plate portion 2, a plurality of short objects are used when the die used for molding with an extruder is small. The arrangement pitch of the ventilation holes 11 ... Is set to about 8 mm to 15 mm, for example. Vent hole 11 ...
Are formed in a single row honeycomb in a horizontal row, and are quadrangles with good ventilation efficiency in the figure, but they may be triangles or hexagons. Further, a plurality of upper and lower rows may be arranged in parallel. At the time of manufacturing, since the direction in which the ventilation holes 11 penetrate is the front-rear direction, a long flat plate is formed by an extruder, so that the front-rear length is cut into a necessary and desired length after the forming.

As shown in the bottom view of FIG. 3, the ventilation cores 3, 3 are bonded to both end portions of the lower surface of the main plates 6, 6 with the ventilation holes 11 being orthogonal to the longitudinal direction of the main plates 6, 6. . Also, as shown in FIG. 1, the left and right ventilation cores 3, 3 on the front side.
The partition wall 3C is diagonally cut so that the width of the lower plate 3B is narrower than that of the upper plate 3A. In the above structure, the wind filter 5 is arranged so as to face the outer side surfaces of the ventilation cores 3, 3 at predetermined intervals so as to face the ventilation holes 11 ...

As shown in FIG. 1, the wind eliminator 5 is formed in a substantially L-shaped cross section with a front plate 5B standing on the front surface of a flat substrate 5A, and the width of the substrate 5A is, for example, 30 mm. About 20 mm is bonded to the outer edge of the lower surface of the ventilation cores 3, 3.
A gap of about 10 mm is formed between the front plate 5B and the ventilation hole 11. Also, as shown in FIG.
An outward water blocking portion 5D is formed at the upper end of B.
Further, a curved portion 5C is formed at the intersection of the substrate 5A and the front plate 5B.

As shown in FIGS. 2 and 3, side walls 4 and 4 are adhered to the lower surfaces of the longitudinal ends of the main plates 6 and 6 so as to contact the longitudinal ends of the ventilation cores 3 and 3. The side walls 4 and 4 have elasticity and are configured to bend when the left and right main plates 6 and 6 are bent at the bendable portion 6A. This material may be any material as long as it is waterproof and bendable, such as a closed cell resin molding,
Alternatively, a mixed molded product of a closed cell resin and an open cell resin is used.

This ventilation building roof tile 1 constructed as described above
Are used as shown in FIG. At the top of the building, a ventilation gap 14 having a width of 15 mm to 30 mm is formed between the left and right field boards 13, 13 facing each other. The ventilation gap 14
The ventilation cores 3 and 3 on the left and right of the ventilation ridge roof tile 1 are arranged so as to straddle the roof ridge, and nails (not shown) are nailed to the nail holes 12 of the main plates 6 and 6 and fixed to the insert plate 13 and 13. In this case, the bendable plate 7 on the main plates 6 and 6 in FIG. 1 can be bent, and the side wall bodies 4 and 4 have elasticity, so that the left and right main plates 6 and 6 can be bent as shown in FIG. Can be adjusted to the gradient of the field boards 13, 13. Also, when the ventilation ridge tile rail 1 is a short one and a plurality of tile tiles 1 are connected in series, the side wall body 4,
Since the four parts are closely contacted by elasticity, the waterproof property is also good.

In FIG. 4, reference numeral 15 is a roof tile and 16 is an air flow. Ototo tiles (not shown) are laid on the roof tiles 15 and 15, and at the upper part of the ventilation ridge tiles 1 are Ototo tiles and round tiles (not shown) via a roof soil (clay) (not shown).

In the above structure, the air flow 16 in the attic of the building rises up from the ventilation gap 14 between the field boards 13 and 13 at the top of the building, and the ventilation holes 11 and 1 of the left and right ventilation cores 3 and 3.
1, it is discharged into the space under the roof tile (not shown), is discharged to the outside through the gap between the tiles, and is constantly ventilated. In this case, when the wind is strong, wind and rain enter through the overlapping gaps of the roof tiles, but the presence of the wind removing bodies 5 prevents the rain from entering the vent holes 11. Further, the windbreaker 5 is the substrate 5
Since the curved portion 5C is formed at the intersection of A and the front plate 5B, the contact area with the base plate 13 (roofing 13A) is small, and rainwater that crawls the base plate 13 due to strong wind rises on the front plate 5B. There is no. Further, even if rainwater adhering to the front surface of the front plate 5B is blown by the wind, the water blocking portion 5D prevents the rainwater from entering.

The ventilation holes 11 of the ventilation cores 3 and 3 can ensure ventilation of about 180 square centimeters or more per meter of the ventilation cores 3. This means that a ventilation area 3 having a length of at least 1 meter can be applied to a ceiling area of 16,2 square meters or more, so that the technical standard for ridge ventilation is sufficiently satisfied.

In FIG. 4, the roofing clay (clay) (not shown) on the roof tile 1 of the ventilation wing is indispensable for roofing, but it slides down with time to block the ventilation holes 11 ... Since the non-slip protrusions 8, 8 are erected on the main plate 6, the anti-slip ridges 8, 8 are provided with ventilation holes 11 in order to prevent slipping of the thatched soil arranged above. The situation of being buried by does not occur at all. That is, collapse of the roof tiles and round tiles supported by thatched soil does not occur. Further, the non-slip strips 8, 8 can support the roof tile.

The size of the roof tile differs depending on the place of origin, and the high-grade product has a large thickness. Therefore, in FIG. 4, a gap of about 1 cm may be opened between the anti-slip ridges 8 and the stile above it. In such a case, a means for increasing the height of the anti-slip ridges 8 is a height adjuster 10 shown in phantom in FIG. The height adjuster 10 includes left and right plates 10A and 10B.
A top plate 10C is formed in the upper part between the left and right plates 10A, 10
A plurality of steps 10D ... Is formed on the side surface of B. Therefore, the height of the height adjusting tool 10 can be selected by selecting an appropriate height of the stairs 10D.
By fitting the above to the stairs 9 of the non-slip ridges 8 and 8 from the side, it is possible to easily adjust the height in units of about 1 mm.

The present invention is not limited to the above-mentioned embodiment, and the design can be changed appropriately according to the purpose. For example, the anti-slip strips 8, 8 on the main plate 6 can be arranged in plural with different heights. The main plates 6 and 6 can be integrally formed by connecting the facing surfaces with a soft material without dividing into two. Further, an adhesive layer may be formed on the lower surface of the ventilation core 3, the windbreaker 5, the side wall body 4, etc. to attach release paper. The dimension is an example, and the dimension is not limited to this and is appropriately set according to the actual condition.
