DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation ridge structure in which a roof is communicated with the outside at the top of a roof to provide ventilation.

[0002]

2. Description of the Related Art A typical example of a ventilation ridge structure in which ventilation is performed in a ridge forming the top of a roof in a house is as follows. That is, a ventilation gap communicating with the attic is formed between the uppermost one of the left and right roof tiles laid with a predetermined roof slope, and a face door is respectively placed on the left and right roof tiles. The shelves are juxtaposed with each other, and the roof tiles are covered on the juxtaposed right and left sheaves so as to cover the ventilation gap and the left and right shelves. A ventilation passage (simply an opening, a hole, a gap, or the like, which allows communication between the ventilation gap and the outside) is formed.

In the ventilation ridge structure having the above-described structure, an inorganic molded product is often used as a ridge roof tile. Such a ridge roof tile is generally durable but hard and brittle, and therefore can be used. The width of the roof slope is extremely narrow. On the other hand, since the roof slope of a house is various, it is necessary to prepare various kinds of products having different dimensions and shapes. For this reason, the roof tiles must be produced in a variety of small quantities, and are relatively expensive.

[0004] For example, Japanese Utility Model Publication No. Hei 3-11286 proposes to form curved concave portions that are recessed inward on both sides of a roof tile in order to increase the width of a roof slope that can be handled. The roof tiles with such curved recesses can be handled with the same size and shape even if the roof gradient is slightly different, but since the roof tiles will be supported by the curved recesses on the kasagi, their contact area will be small, When the ridge roof tile is fixed with a nail or the like to the roof, the driving position of the nail or the like is likely to shift or the ridge roof tile is inclined, and it cannot be said that the stability and the workability are good.

On the other hand, sheet metal ridges used in place of ridge roof tiles can be bent or bent relatively easily. Although it can be manufactured widely and at low cost, it is easy to bend or bend because it is thin. By the way, Japanese Patent Application Laid-Open No. 63-74948 describes a ventilation building structure in which the above-mentioned sheet metal building can be used. In the ventilation ridge structure described in this publication, a steel plate member in which a rising piece is erected on an upper surface portion of an elastic body portion made of a synthetic resin foam or the like of a face door placed on a roof tile is attached, A cover is arranged on the rising piece of the member, and a cover is formed from a rectangular cover and a horizontal cover that bends downward from both ends of the cover so as to cover each part on the cover. The building is covered with a ridge.

In the ventilation ridge structure described in this publication, a rising piece of a steel plate member separates the elastic body portion of the cap and the face door from each other to form a ventilation opening (gap) therebetween. Through this, ventilation of the house (attic) will be performed.

[0007]

However, in the ventilation ridge structure described in the above publication, the ventilation opening is formed only on the upper surface side of the face door. Therefore, for example, when the laterally covering plate portion of the sheet metal ridge is slightly bent inward (the side of the door and the side of the skirting) due to a storm or the like, the ventilation opening is closed and the ventilation passage connecting the attic and the outside is provided. Is shut off, and the ventilation capacity is significantly reduced.

As one measure for solving such a problem, for example, it is conceivable to reinforce a sheet metal ridge so as not to bend easily. However, reinforcing the ridge is costly. In addition, the advantage of the sheet metal ridge and wrapper that the width of the roof slope that can be flexibly bent or flexibly accommodated is wide is lost. In addition, in the conventional ventilation ridge structure, as shown in the above two publications, although the ridge roof tile or the ridge parcel usually covers the headdress, the side of the skirt tile and the ridge roof tile or the ridge parcel are usually covered. The space between the inner surface (rear surface) and the upper surface of the roof tile and the lower end of the ridge tile or ridge is open for ventilation, etc., so when wind and rain are strong, flying water may flow inside the ridge or ridge. Invasion and wet the Kasagi. For this reason, there is a problem that the cap is rotten and easily decayed, and the overall durability is reduced.

In view of the foregoing, the present invention can reliably and sufficiently perform ventilation, can increase the width of the roof slope that can be supported, and improve the workability and durability to improve quality. It is an object of the present invention to provide a ventilation ridge structure that can be configured at a low cost without dropping the whole.

[0010]

In order to achieve the above-mentioned object, a ventilation ridge structure according to the present invention comprises a roof tile having a predetermined roof slope and a roof tile at the top of the roof tiles. A ventilation gap leading to the attic is formed between the roof tiles, and the shelters are juxtaposed on the left and right roof tiles via face doors, respectively. Ventilation spacers for covering the side surfaces are arranged to face each other with the ventilation gap interposed therebetween, and a sheet metal ridge is covered on the ventilation spacer so as to cover the ventilation gap and the left and right ventilation spacers. The ventilation spacer has an upper surface plate portion and a side plate portion bent downward from one end of the upper surface plate portion, the plurality of protrusions projecting from each other at intervals, and the ventilation spacer Due to the above ridge package Configured ventilated passage for communicating the said ventilation gap and the outside formed therebetween is allowed et apart.

The material of the ventilation spacer used in the ventilation building structure of the present invention is not particularly limited, and can be manufactured by appropriately molding a synthetic resin, a sheet metal, or the like. It may be molded integrally with the part,
It may be formed separately and joined later. Also,
The protrusion formed on the ventilation spacer may be a simple protrusion or a step. The shape is not particularly limited, but the upper surface is flat with a rib shape, and the upper surface plate portion and the side plate portion are provided. It is preferable that the height of the projections protruded from the base end face is equal to each other, and furthermore, the plurality of projections formed on the upper face plate are formed on the side face plate so as to form a labyrinth. As a preferred embodiment, they are arranged so as to overlap each other when viewed from the side.

[0012]

[Operation] In the ventilation ridge structure according to the present invention configured as described above, since a plurality of projections are formed at intervals on the top plate and the side plate of the ventilation spacer, The ventilation spacer secures a gap that serves as a ventilation passage between the top and side hoods of the ridge and the side of the top and opposite sides of the skirting, and bends inside the ridge. Alternatively, it also serves to prevent deflection and keep the left and right lower ends of the ridge packet apart from the top surface of the roof tile. As a result, even when using an inexpensive sheet metal ridge that can be bent or bent, it is possible to reliably prevent a situation where the ventilation passage is blocked, and to stably maintain a necessary and sufficient ventilation capacity. .

In addition, the ventilation spacers are separately placed on the left and right caps, and the ridge is flexible or bendable, so that the width of the roof slope that can be accommodated is widened. The versatility of is improved, and it can flexibly respond to various roofs. In addition, since the ventilation spacer covers the upper and lower sides of the right and left caps so as to cover the lower side, water from the outside is blocked by the ventilation spacers, making it difficult to reach the caps, and the caps are wet. The situation that rots as much as possible is suppressed as much as possible. As a result, the Kasagi is less likely to decay, thereby improving the overall durability.

Further, the main components including the face door, the cap, the ventilation spacer, and the ridge packet are assembled in such a manner that they are sequentially stacked and fixed as a whole, and each member other than the ventilation spacer is assembled. Since the configuration may be the same as that of the conventional product, the construction is simple and easy, and the manufacturing cost and the construction cost of each member can be kept low. As a result, the whole can be provided at low cost.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 are an exploded perspective view and a longitudinal sectional view showing one embodiment of a ventilation building structure according to the present invention. In this example, a flat roof tile 3 made of a synthetic resin and having a convex portion at a front end portion is laid on the left and right sides with a predetermined roof slope on a base plate 2 located on the indoor side. A ventilation gap S (FIG. 2) is formed between the uppermost one of the left and right roof tiles 3 and between the upper ends of the left and right baseboards 2 to communicate with the attic. Also, on the left and right roof tiles 3, caps 5 are juxtaposed via a face door 4 made of synthetic resin such as elastic foam or rubber. Each of the pair of face doors 4 and the shade 5 arranged side by side has a rectangular cross-section, and is disposed opposite to the roof tile 3 at substantially the same inclination angle (roof gradient), and in the front-rear direction (depth direction) of the roof. The space (path) that forms the upper part of the ventilation gap S is secured between the opposing side surfaces of the right and left caps 5.

The ventilation spacers 10 are disposed on the pair of juxtaposed caps 5 so as to face left and right across the ventilation gap S, and the sheet metal ridge 6 is placed on the ventilation spacers 10. Are the above-mentioned gap S for ventilation,
And it is covered so as to cover the ventilation spacer 10. The ridge packet 6 is composed of an upper cover plate portion 6a composed of a left plate portion and a right plate portion having a rectangular cross section that can be bent at the center portion, and a horizontal cover plate that is bent downward from both ends of the upper cover plate portion 6a. Part 6b;

On the other hand, the ventilation spacer 10 is integrally formed of synthetic resin, and as shown in detail in FIG.
And a side plate 14 bent downward at a right angle from one end of the top plate 12. The top plate 12 has a U-shaped cross section with a flat upper surface, and a protruding height from the base end surface. As shown in FIG. 4, a plurality of equal rib-shaped protrusions 16 are spaced at appropriate intervals in the width direction and the front-rear direction, and overlap each other as seen from the side plate 14 so as to form a labyrinth. It is protruded as follows. Also, the side plate portion 14
Are provided with a plurality of trapezoidal projections 17 having the same width (height) and a flat upper surface at intervals. The ventilation spacer 10 may be a relatively long one covering the entire length of the cap 5 or may be relatively short alone and cover a whole length of the cap 5 by arranging a plurality of them in series. May be something.

The construction of the ventilation building constructed as described above is performed as follows. First, the face doors 4 are arranged in parallel on the left and right roof tiles 3 along the depth direction of the roof, and temporarily fixed by an appropriate means such as an adhesive if necessary. Next, in a state where a pair of right and left caps 5 are juxtaposed on each face door 4,
The ventilation spacers 10 are arranged on the right and left caps 5 so as to cover the entire length thereof.

At this time, since the ventilation spacers 10 are separately placed on the side boards 5 arranged side by side, even if the position of the top boards 5 fluctuates, there is no need to be affected by such a change. Since it is only necessary to put the same shape on the cap 5 so as to face the same, the handling is extremely simple. Further, the ventilation spacer 10 has a top plate 12 having a length corresponding to the width of the coping 5 and a side plate 14 bent at a right angle to the top plate 12 to provide ventilation. The back surface of the spacer 10 can be brought into contact with the upper surface of the side-by-side cap 5 and the side surface on the opposite side, so that the ventilation spacer 10 can be easily positioned and the ridge 6 The gap between the left and right lower end portions (locking projections 6d) and the roof tile 3 is appropriately secured. In addition, if the double-sided tape or the like is stuck on the back surface side of the ventilation spacer 10, the above operation can be performed more easily.

After the ventilation spacer 10 is placed on the coping 5 in this manner, the nail 7 (FIG. 2) is connected to the ventilation spacer 1.
Kasagi 5, face door 4, and roof tile 3 in a direction perpendicular to the top of 0
And is driven so as to reach the base plate 2. In this case, if a through-hole or a concave portion is formed in advance in each member as necessary, the positioning and driving operation at the time of nailing becomes easy.

Subsequently, the ridge 6 is covered so as to cover the members fixed as described above. In this case, the top plate 12 of the ventilation spacer 10 is arranged along the roof gradient, and the side plate 14 is bent at a right angle to the top plate 12, so that The back surfaces of the portion 6a and the lateral cover plate portion 6b are respectively the upper plate portion 1 of the ventilation spacer 10.

d is locked to the outer edge of the trapezoidal convex portion 17 of the side plate portion 14.

Then, with the ridge 6 in contact with the ventilation spacer 10 in this manner, the nail 9 is driven so as to penetrate through the side covering plate portion 6b of the ridge 6 into the cap 5. Thereby, the ridge 6 is fixed, and the assembling of each part is completed.
Also in this case, the horizontal covering plate portion 6b of the ridge
If a through-hole or a concave portion is formed in advance, positioning and driving work at the time of nailing becomes easy. Then, a necessary operation such as attaching a cover or the like to the opening at the front and rear ends of the ridge 6 and closing the opening is performed. Thereby, the construction of the ventilation building structure is completed.

In the ventilation ridge structure of the present embodiment constructed as described above, the upper plate 1 of the ventilation spacer 10 is provided.
2 and the rib-shaped protrusion 16 and the trapezoid-shaped protrusion 17 protruding from the side plate 14, the ventilation passage R is provided between the cap 5 and the ridge 6.
Is secured. That is, in this example,
The ridge 6 is separated from the coping 5 by the rib-shaped protrusions 16 and the trapezoidal protrusions 17 of the ventilation spacer 10, as shown by arrows P in FIG. With the gap formed between the roof tile 3 and the doorway as an entrance, the side opposite to the side of the juxtaposed trees 5 and the side covering plate portion 6b of the ridge 6
And the space formed between the upper surface of the cap 5 and the upper cover 6a of the ridge 6 becomes a ventilation passage R, and the space of the house is formed through the ventilation passage R and the above-described ventilation gap S. Ventilation is provided.

In this case, a plurality of rib-shaped projections 1 are provided on the upper surface plate portion 12 and the side surface plate portion 14 of the ventilation spacer 10, respectively.
6, since the trapezoidal projections 17 are provided in a protruding manner, the ventilation spacer 10 is formed on the upper surface of the coping 5 and the side surface on the opposite side to the ridge 6
Between the upper cover plate portion 6a and the horizontal cover plate portion 6b.
6, in addition to securing a gap to be a ventilation passage R corresponding to the height of the projection of the trapezoidal projection 17, in addition to preventing inward bending or bending of the ridge 6 and roofing the left and right lower ends of the ridge 6 It also serves to keep the roof 3 away from the upper surface. As a result, even when using an inexpensive sheet metal ridge that can be bent or bent, the situation that the ventilation passage R is blocked is reliably prevented, and the necessary and sufficient ventilation capacity is stably maintained. obtain.

Further, the ventilation spacer 10 is provided on the left and right shelves 5.
It is placed separately on top, and the ridge 6 can be bent or flexed, so that the width of the corresponding roof slope can be widened,
The versatility of ventilation spacers and ridges is enhanced, and it can flexibly cope with various roofs. Furthermore, since the ventilation spacer 10 is covered so as to cover the upper surface of the left and right hems 5 and the side surface located on the lower side, water from the outside is blocked by the ventilator and it is difficult to reach the hess 5, The situation in which the cap 5 gets wet and rot is suppressed as much as possible. As a result, since the cap 5 is less likely to decay, the overall durability is improved.

Further, the face door 4, the cap 5 and the ventilation spacer 1
0, and the main components consisting of the ridge 6 can be assembled by simply placing them one on top of the other and fixing the whole, and the components other than the ventilation spacer 10 may have the same configuration as the conventional product. Therefore, the construction is simple and easy, and the production cost and construction cost of each member are kept low.
As a result, the whole can be provided at low cost.

In addition, the rib-shaped protrusions 16 protruding from the upper surface plate portion 12 of the ventilation spacer 10 are spaced from each other at appropriate intervals in the width direction and the front-rear direction, and are formed so as to form a labyrinth. Since they are arranged so as to overlap each other when viewed from the part 14, even if flying water enters from the entrance (P) of the ventilation passage R, the flying water will not
6 hampers its progress and is twisted and twisted, making it almost impossible to reach the opposite side of the Kasagi 5. Therefore,
Rainwater is reliably prevented from entering the inside (opposite side) of the cap 5 or entering the house (attic).
In addition, since the lower surface on the opposite side of the cap 5 is exposed, there is a possibility that it will be wet by flying water, but since such a portion is relatively well ventilated, it hardly rots.

Although the above-mentioned rib-shaped projections 16 are linearly extended along the front-rear direction of the ventilation spacer 10, instead of the rib-shaped projections 16 as shown in FIG. If at least one end of the portion 19 is slightly bent toward the side plate portion 14, the progress of rainwater can be more effectively prevented, and further, as shown in FIG.
If the waterproof rib 21 having a lower protruding height than the rib-shaped convex portion 16 is provided at the end on the side opposite to the side surface plate portion 2 so as to cross the upper surface plate portion 12 in the front-rear direction, the ventilation function is impaired. Without infiltrating rainwater into the house.

As shown in FIG. 7, instead of the trapezoidal projections 17, the side plate of the ventilation spacer 10 has a plurality of plate-like projections 23, like the top plate 12, as shown in FIG. 24
May be arranged so as to be spaced from each other and overlap each other when viewed from the upper surface plate portion 12 side. Also in this case, the plate-like projections 2
A ventilation passage is formed between 3 and 24, and it is difficult for water to flow therethrough.

Next, another example of the ventilation building structure according to the present invention will be described with reference to FIGS. In the following drawings, portions corresponding to the respective portions shown in FIGS. 1 to 3 described above are denoted by the same reference numerals, including the entirety, and redundant description thereof, and description of common portions of the operation and effect are provided. Is omitted. The ventilation spacer 10 used in the examples shown in FIGS. 9 and 10 is, as shown in FIG. 8, a lower protruding side portion which is bent outward at right angles from the lower end of the side plate portion 14 and protrudes. 25 and a support protrusion 27 that is bent outward at right angles from the lower end of the trapezoidal protrusion 17 and protrudes.

As shown in FIG. 10, a lower end cover plate portion 6c formed on the ridge packet 6 and bent outward from the lower end of the horizontal cover plate portion 6b is mounted on the bearing convex portion 19 as shown in FIG. While being brought into contact with each other, the locking projection 6d folded inward from the lower end cover plate 6b is hooked. By doing so, even if the cap 5 and the like are shifted or tilted from the appropriate positions, the left and right lower ends of the ventilation spacer 10 abut the roof tile 3, but the left and right lower ends of the ridge 6. Since the (locking projection 6a) is securely separated from the roof tile 3, a gap is always secured between the lower right and left lower ends of the ridge 6 and the roof tile 3 as an entrance and exit of the ventilation passage R. As shown by the arrow Q in FIG. 5, ventilation is performed through the gap in the same manner as in the ventilation building structure shown in FIG.

FIGS. 11 and 12 show a ventilation spacer 10 used in still another embodiment. In this embodiment, an upward supporting projection which is bent upward from the outer end of the lower protruding side portion 25 and projects therefrom. A lower end cover plate portion 6c of the ridge 6 is mounted on the upward bearing projection 29, as shown by a dashed line in FIG. 12, and a locking projection 6d is engaged with the upward bearing projection 29. Also in this example, a gap serving as an entrance and exit of the ventilation passage is secured between the lower protruding side portion 25 and the lower end portion of the ridge 6, and the same operation and effect as in the above-described example can be obtained.

[0033]

As is apparent from the above description, according to the ventilation ridge structure of the present invention, an inexpensive sheet metal ridge packet that can be bent or bent and has a relatively simple structure is used. In addition, ventilation can be performed reliably and sufficiently, and the width of the roof slope that can be used can be widened, and furthermore, the workability and durability are improved, and the whole is inexpensive without lowering the quality. An excellent effect that can be provided is obtained.
