Description: TECHNICAL FIELD [Detailed description of the invention]

【0001】

[Technical field to which the invention belongs]

The present invention relates to a ridge ventilation device provided for a building with a tiled roof such as a general house, and a ridge ventilation structure using these.

【0002】

[Conventional technology]

Conventionally, as a roof tile for ventilation, for example, as described in Japanese Patent Application Laid-Open No. 11-172858, it is a roof tile laid on the top of a house and has a rectangular shape having a ventilation hole in a substantially central portion of the roof tile located at the lower stage. Protrusions (convex parts) are provided, and rectangular notches (concave parts) that engage with the rectangular protrusions (convex parts) of the lower roof tile are provided on the front and rear edges of the roof tile located on the second stage of the roof tile. ) Is formed, and the engagement between this protrusion and the notch prevents the stacked upper roof tiles from shifting left, right, front and back, and the surface of the second roof tile is provided with a stepped protrusion. It is formed so as to create a breathable gap between the tiles and the tiles stacked on the third stage. Then, the hot air, odor, etc. accumulated in the attic are discharged through the ventilation holes provided in the lower roof tile and the gap formed between the second and third roof tiles to perform ventilation.

【0003】

Further, as another conventional ridge ventilation structure, the one shown in FIG. 20 has been proposed. In FIG. 20, a roof tile 43 is laid on a crosspiece 46 provided on a roof base material 41 such as a field board or roofing so that one end is caught. A ridge opening 42 is provided at the top of the roof base material 41 so that indoor air can pass through as an updraft, and above the ridge opening 42, a rafter that supports the rafter 46 and ventilates the indoor air. The support / ventilation structure 47 is fixed to the roof base material 41 by its legs 48 with nails (not shown) or the like. In addition, ventilation holes 49A, 49B, and 49C through which air passes are bored in the purlin support and ventilation structure 48.

【0004】

Then, while the ridge tile 50 is fixed to the rafter 46 by a fixing screw 51 with packing, a passage forming member 52 is arranged along the inclined lower surface of the ridge tile 50 so as to form a passage with the lower surface, and the upper end portion 53 thereof is arranged. It is fixed to the purlin 46 by nails (not shown). Further, the lower end portion 54 is arranged as a sealing member so as to be in contact with the thatched soil 55 appropriately filled on the roof tile 43 and in contact with the tip portion 56 of the ridge tile 50. Ventilation holes 49D and 49E through which air passes are also bored in the passage forming member 52. In such a configuration, the indoor air that becomes hot air and rises from below passes through the ridge opening 42 and the ventilation holes 49A, 49B, 49C, 49D, 49E in order as shown by the arrows in FIG. Finally, it is discharged to the outside so as to wrap around the tip 56 of the ridge tile.

【0005】

[Problems to be Solved by the Invention]

However, in the former ventilation ridge tile mentioned above, since the shape of the ridge tile is different for each stacking stage, it is necessary to prepare several kinds of complicated shapes. Not only is storage management complicated, but construction work is complicated and expensive, and it tends to be limited to luxury homes. Also, in general, from the viewpoint of strength and material cost, the size of the rectangular protrusion provided on the lower roof tile and the notch of the second roof tile fitted to this protrusion is limited, so it is provided on the protrusion. The vents became smaller by themselves, so they were not always sufficient in terms of ventilation.

【0006】

Further, in the latter ridge ventilation structure that does not use multiple ventilation ridge tiles as described above, since the ventilation passage is formed under the simple mountain-shaped ridge tile 50, it is different from the tile material. For example, a passage forming member 52 made of a metal plate was required, and a purlin 46 was required as a means for fixing the passage forming member 52. As a result, the structure and construction work became complicated, and the problem that the cost had to be increased was included. In addition, rainwater easily enters through the ventilation passage, and even if it does not enter the room, the roof base material may get wet and rot, which may reduce durability. Furthermore, in such a form of ridge ventilation structure, the hipped roof Since rainwater easily enters the corner ridges such as the roof, it is difficult to apply it, and there is a problem that the ventilation volume is reduced accordingly.

【0007】

In view of the above problems, the present invention has a simple structure, easy construction workability, sufficient ventilation volume, and a ventilation ridge tile, a ridge ventilation device, and the like, which can be easily applied to a hipped roof. The purpose is to provide a ridge ventilation structure using the above at low cost.

[Effect of the invention]

As described above, the ridge ventilation device A1 of the present invention is made of a portal member, and by providing a fixing portion on the upper portion of the portal member, the structure is extremely simplified and the strength is sufficient.

【0061】

In the ridge ventilation device A2 of the present invention, since the space formed between the adjacent connecting members is used as the ventilation path, it is not necessary to form a ventilation port in the members, and the lower member X and the portal member Since Y and the connecting member Z can be manufactured by extrusion molding, a significant cost reduction can be achieved. Further, since the lower member X and the upper member Y are fitted by the connecting member Z, the strength is sufficient.

【0062】

Further, since the ridge ventilation devices A1 and A2 of the present invention directly fix the ventilation ridge tile to the fixed portion of the ridge ventilation device without requiring a purlin, the construction workability is dramatically improved. An inexpensive ridge ventilation structure can be provided.

【0063】

Further, in the ventilation ridge tile used in the present invention, the inner member of one ridge tile unit is polymerized so as to be covered by the outer member of the other ridge tile unit, and a ventilation path is formed between the outer member and the inner member. Therefore, only one type of ridge tile is required (three types even if the ridge tiles at both ends are added), and as a result, it is easy to manage the manufacturing type and inventory of the finished product, and the construction work is easy.

【0064】

Further, in the ventilation ridge tile used in the present invention, the ventilation path formed by the outer member and the upward control protrusion of the inner member is strong from the outside because the portion in contact with the outside is formed in a substantially horizontal direction. Even if the wind and rain hit the ventilation building tile, the direction of the wind and the direction of the ventilation path are different by about 90 degrees, so it is difficult for the wind and rain to enter the ventilation path. The protrusions prevent the intrusion and flow down along the inclined groove formed by the control protrusions.

Further, in the ventilation ridge tile used in the present invention, by providing a downward control protrusion on the outer member, a zigzag-shaped ventilation path is formed by the downward control protrusion and the upward control protrusion of the inner member to stop water supply. Drainage and wind controllability will be further improved. Further, by forming the inner member so as to descend in the direction of the outer member, the water-stopping / drainage property and the wind controllability are further improved.

Further, by providing the ventilation path forming spacer, the polymerization of the building tile units becomes easy, the workability is greatly improved, and the ventilation path of a predetermined size is easily formed. Furthermore, by providing a ventilated partition wall in the ventilation path, it is possible to prevent the invasion and nesting of insects such as small birds and bees.
