[0003]

When the roof structure is a ridge, it is impossible to form a ventilation hole in the wall behind the cabin, and there is a problem in the ventilation at the top only with the ventilation hole behind the eaves. However, from October 1, 1998, the technical standards for housing to which the Japan Finance Corporation system was applied were revised, and if air vents were provided behind the eaves and exhaust vents using exhaust pipes and other instruments were provided, The ratio of the effective area to the area of the ceiling is 1/900 or more, and the exhaust hole is provided at the top of the back of the hut as much as possible. The ratio of the effective area of the exhaust hole to the area of the ceiling is 1/1600 or more. That is, the regulations have been enacted, and the number of wings has been increasing to reduce construction costs. Therefore, there is a need for a ventilated roof structure that is inexpensive, has excellent workability, and conforms to the above technical standards in response to these laws and regulations and the trends of the times. The present invention has been developed in view of those circumstances with the aim of providing an inexpensive ventilation building with excellent ventilation and workability.

In the vent core, a plurality of vent holes which extend long in the extrusion direction of a flat plate extruded by extrusion molding are formed in parallel on the left and right, and are formed by cutting the width before and after the extrusion to a predetermined width. It can be.

[0009]

The present invention configured as described above has the following operation.

On the roof, a ventilation gap having a width of about 2 cm is formed between the left and right end faces of the ridges on the roof, and when the back of the hut is ventilated, the ventilation ridge tile is closed so as to close the ventilation gap from above. Attach the crosspiece. The hot air behind the hut enters the space between the left and right ventilation cores through the ventilation gap and is exhausted to the space under the roof tile through the respective ventilation holes of the left and right ventilation cores.

The bendable portion at the parallel intermediate portion of the left and right main plates is:
Easy to bend when bending the left and right main boards according to the roof slope.

The side walls at both longitudinal ends of the ventilation core close the ventilation gaps at both ends in the longitudinal direction of the building, and make the joints close when a plurality of short ventilation building tiles are connected in series. In addition, when the left and right main plates are bent at the opposed portions according to the roof gradient, they can be easily bent.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a vertical sectional front view of the ventilation ridge tile, FIG. 2 is a perspective view of the ventilation ridge tile, and FIG. 3 is a bottom view of the ventilation ridge tile. In FIG. 1, the ventilation ridge tile 1 is composed of a main plate portion 2, ventilation cores 3, 3, side walls 4, 4 and wind removers 5, 5.

In FIG. 1, a bendable plate 7 is adhered to the upper portion of the main plate portion 2 at the center of the width in which left and right main plates 6, 6 having a width of about 6 cm are arranged in parallel, so that the left and right main plates 6, 6 can be bent at the center. A bendable portion 6A is formed. On the left and right upper edge portions of the main plates 6, 6, an upward anti-slip ridge 8 having a height of about 5 mm to 20 mm is formed along the longitudinal direction. The anti-slip ridge 8,
A pair of fitting grooves 9, 9 for fitting the height adjuster 10 is formed along the length of the upper edge of the left and right sides of 8. The length of the main plate portion 2 can be increased since it is extruded, but since it is a member used on a roof, it is 1200 when sold.
It is set to about millimeter.

In FIGS. 1 and 2, the ventilation core 3 has a plurality of partition walls 3C having a height of about 10 mm 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. A plurality of ventilation holes 11 are formed. The length is set to be the same as the length of the main plate portion 2. However, when the mold used for molding by an extrusion molding machine is small, a plurality of short objects are used. The arrangement pitch of the ventilation holes 11 is set, for example, to around 8 mm to 15 mm. Vent hole 11 ...
Are formed in a horizontal row in a single-row Honeycomb system and are squares with good ventilation efficiency in the figure, but may be triangular or hexagonal. Also, a plurality of juxtapositions may be arranged vertically. At the time of manufacture, since the direction through which the air holes 11 penetrate is formed as a long and flat plate by an extruder with the front-rear direction, the front-rear length is cut to a required length after molding.

As shown in FIG. 3, the vent cores 3 and 3 are bonded to the lower end portions of the main plates 6 and 6 with vent holes 11 perpendicular to the length of the main plates 6 and 6. . Also, as shown in FIG.
The partition wall 3C is cut obliquely so that the width of the lower plate 3B is smaller than the width of the upper plate 3A. In the above configuration, the wind remover 5 is disposed so that the left and right outer surfaces of the ventilation cores 3 and 3 face and cover the ventilation holes 11 at predetermined intervals.

As shown in FIG. 1, the wind remover 5 is formed in a substantially L-shaped cross section with a front plate 5B rising on the front surface of a flat substrate 5A. The width of the substrate 5A is, for example, 30 mm. About 20 mm is adhered to the outer edge of the lower surface of the ventilation cores 3 and 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-proof section 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 be in contact with the longitudinal ends of the ventilation cores 3 and 3, respectively. The side walls 4, 4 have elasticity, and are configured to bend when the left and right main plates 6, 6 are bent at the bendable portion 6A. This material may be any material as long as it is waterproof and bendable.
Alternatively, a mixed molded article of a closed-cell resin and an open-cell resin is used.

The ventilation building roof tile 1 constructed as described above
Are used as shown in FIG. At the top of the ridge, a ventilation gap 14 having a width of 15 mm to 30 mm is formed between the left and right base plates 13 and 13 facing each other. The ventilation gap 14
The ventilation cores 3 on the left and right sides of the tile 1 of the ventilation ridge are arranged so as to straddle, and nails (not shown) are inserted into the nail holes 12 of the main plates 6 and 6 and nailed to the base plates 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 walls 4 and 4 have elasticity and can be bent. Therefore, as shown in FIG. Can be adjusted to the gradient of the base plates 13. Also, when the ventilation ridge tile 1 is short and a plurality of tiles are arranged in series,
Since the four are closely contacted by elasticity, the waterproofness is also good.

In FIG. 4, reference numeral 15 denotes a roof tile, and 16 denotes an air flow. On the roof tiles 15 and 15, a roof tile (not shown) is roofed, and on the roof tile 1 of the ventilation building, a roof tile (not shown) and a round roof tile are disposed via a roof (clay) not shown.

In the above construction, the airflow 16 behind the hut of the building rises up from the ventilation gap 14 between the base plates 13 at the top of the building, and the ventilation holes 11 of the left and right ventilation cores 3 are formed.
It goes out into the space under the roof tile (not shown) along 1 and is discharged outside through the gap between the roof tiles, and is constantly ventilated. In this case, when the wind is strong, the wind and rain enter from the overlapping gap of the tiles, but the presence of the wind removers 5 and 5 prevents the rain from entering the ventilation holes 11. The wind remover 5 is a 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 the rainwater that crawls on the base plate 13 due to the strong wind rises on the front plate 5B. There is no. Furthermore, even if the rainwater adhering to the front surface of the front plate 5B blows up due to the wind, the intrusion is prevented by the flood protection section 5D.

The ventilation holes 11 of the ventilation cores 3, 3 can secure ventilation capable of supporting about 180 cm 2 or more per meter of the length of the ventilation cores 3. This means that a single ventilation core 3 having a length of at least one meter can cover a ceiling area of 16,2 square meters or more, and thus sufficiently satisfies the technical standard for ridge ventilation.

In FIG. 4, the roofing clay (clay) (not shown) on the roof tile 1 of the ventilation building is indispensable for roofing, but slides down with time to close the ventilation holes 11. The main plates 6 are provided with non-slip projections 8, 8 so that the non-slip projections 8, 8 are provided with ventilation holes 11 in order to prevent slipping of the roof soil disposed on the upper portion. There is no chance of being buried by. That does not cause the collapse of the shingles and round tiles supported by the roofing material. The non-slip strips 8 can support the roof tile.

Tiles vary in size depending on the place of production, and high-grade products are thicker. Therefore, in FIG. 4, a gap of about 1 cm may be opened between the non-slip ridges 8, 8 and the crosspiece thereon. In such a case, a means for increasing the height of the non-slip protruding ridges 8, 8 is a height-adjusting device 10 shown by a virtual line in FIG. The height adjustment device 10 includes left and right plates 10A, 10B.
A top plate 10C is formed in the upper portion between the left and right plates 10A, 10A.
A plurality of steps 10D are formed on the side of B. Therefore, the height of the height adjuster 10 is selected by selecting an appropriate height of the stairs 10D.
Can be easily fitted to the stairs 9 of the anti-slip ridges 8, 8 from the side, so that the height can be easily adjusted by about 1 mm.

It should be noted that the present invention is not limited to the above-described embodiment, and the design can be appropriately changed according to the purpose. For example, a plurality of non-slip strips 8 on the main plate 6 can be provided with different heights. The main plates 6 and 6 can be integrally formed by connecting the opposing surfaces with a soft material without being divided into two. An adhesive layer may be formed on the lower surface of the ventilation core 3, the wind remover 5, the side wall 4, and the like, and a release paper may be attached. The dimensions are merely examples, and are not limited to these dimensions, and are set as appropriate according to the actual situation.
