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 as the roof tile. 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 as a face door arranged on a roof tile is attached. A cover is arranged on the rising piece of the steel plate member, and an upper cover plate having a rectangular shape in cross section and a horizontal cover plate bent downward from both ends of the upper cover plate so as to cover each part on the cover. It is constructed by covering a ridge packet consisting of

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. For this reason, 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 attic communicates with the outside. There is a problem that the ventilation passage is blocked 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. Openings or gaps are formed between the inner surface (back surface) and the upper surface of the roof tile and the lower end of the ridge roof tile or ridge wrap, so that when the wind and rain is strong, flying water will flow into the ridge roof tile. Or invade the inside of the ridge and wet the Kasagi. For this reason, there is a problem that the cap is rotten and easily decayed, and the overall durability and life are reduced.

In view of the above, the present invention can reliably and satisfactorily perform ventilation, can increase the width of the roof slope that can be handled, and minimize the manufacturing cost of the members used. It is another object of the present invention to provide a ventilation building structure that can be constructed at a low cost without deteriorating quality by improving workability and durability.

[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 roof tiles are juxtaposed on the left and right roof tiles through face doors, respectively. A ventilation spacer having a pair of side plate portions bent downward from the left and right ends thereof and a top surface plate portion having a substantially U-shaped cross section that is bendable is covered,
A sheet metal ridge is covered on the ventilation spacer so as to cover the ventilation spacer, and the ventilation spacer has a ventilation opening connected to the ventilation gap in its upper surface plate. In addition, a plurality of projections are respectively provided on the upper surface plate portion and the side surface plate portion so as to be spaced apart from each other, and the ridge is separated from the capping tree by the ventilation spacer, and the space between the ridges is provided therebetween. It is configured such that a ventilation passage communicating the ventilation gap and the outside is formed.

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 may be a simple protrusion or a step, and the shape thereof is not particularly limited. However, it is preferable that each protrusion has the same height from the base end face.

Further, the ventilation opening formed in the ventilation spacer is preferably formed in the center of the upper plate, but it is not always necessary, for example, a large number of through holes near the center. May be scattered. In short, as long as it is formed at a position where the upper surface of the ventilation spacer and the ventilation gap can be communicated, the position, shape,
And the number may be appropriately selected.

[0013]

[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, Ventilation spacers provide a gap between the top and side walls of the right and left caps and the opposite side, and the top and side cover panels of the ridge, as well as the inside of the ridge. It also serves to prevent bending or bending of the roof tile and to keep the lower right and left 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. .

Further, since the ventilation spacer and the ridge are both bendable or bendable, the width of the roof slope that can be accommodated is widened, and the versatility of the ventilation spacer and the ridge is enhanced, so that it can be applied to various roofs. Can respond flexibly. 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 durability of the whole is improved because the Kasagi hardly rots.

Further, it is assembled simply by placing the main components including the face door, the cap, the ventilation spacer, and the ridge packet one by one and sequentially fixing the entire components. 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.

[0016]

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 to face the roof tile 3 at substantially the same inclination angle (roof slope), and in the front-back 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 placed on the left and right side caps 5 so as to straddle both of them.
The ridge 6 is covered on the ventilation spacer 10 so as to cover the ventilation spacer 10.
The ridge packet 6 is made of sheet metal, and is formed to be bent at a central portion thereof. The upper cover plate portion 6a is composed of a left plate portion and a right plate portion having a substantially rectangular cross section. A pair of horizontal cover plates 6b bent downward from the left and right ends of the portion 6a, and the locking projections 6 bent inward from the lower ends of the horizontal cover plates 6b.
d, and each part is elastically bendable at a corner portion.

On the other hand, the ventilation spacer 10 is integrally molded from a synthetic resin, and can be bent or bent as shown in detail in FIG.
It has an upper surface plate portion 12 having a substantially rectangular cross section composed of 2a and a right side plate portion 12b, and a pair of side plate portions 14 bent downward at right and left ends from right and left ends thereof. A plurality of ventilation openings 20 are formed in the upper surface plate portion 12 at a central portion thereof (one end side of the left surface plate portion 12a and the right surface plate portion 12b) at appropriate intervals in the front-rear direction. Except in the vicinity, a large number of plate-like projections 16 having the same height from the base end face
Are provided in parallel in the front-rear direction at appropriate intervals. Further, the side plate portion 14 is bent at a right angle from the plate-shaped convex portion 16 of the upper surface plate portion 12 so as to be integrally connected, and crosses the side plate portion 14 in the width (height) direction. Are protruded in parallel at appropriate intervals in the front-rear direction.

The ventilation spacer 10 may be a relatively long one that covers the entire length of the coping 5 with a single piece, or the ventilation spacer 10 may be relatively short by itself and arranged in series to provide a total length of the coping 5. It may be something that covers
Further, in the ventilation spacer 10 of the present example, the ventilation opening 20 is formed over both the left face plate part 12a and the right face plate part 12b so as to be located at the center of the upper face plate part 12, It is not always necessary to do so. For example, a large number of through-holes may be separately formed in the left side plate portion 12a and the right side plate portion 12b, and these may be used as ventilation openings. As long as it is formed at a position where the side and the ventilation gap S can communicate with each other, the position, shape, and number thereof may be appropriately selected, but as described above, the left side plate portion 12a and the right side plate portion If it is formed so as to straddle both sides 12b, there is a secondary advantage that the upper surface plate portion 12 is easily bent.

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 left and right caps 5 so as to straddle both of them. In this case, the ventilation spacer 10 may be simply placed on the cap 5. However, in order to increase the stability, for example, a double-sided tape is adhered to the back of the ventilation spacer 10 and fixed to the cap 5. You may make it.
In addition, the upper surface plate portion 12 of the ventilation spacer 10 is bent corresponding to the inclination of the roof, and the side surface plate portion 14 is bent at a right angle to the upper surface plate portion 12.
Can be brought into contact with the upper surface of the juxtaposed cap 5 and the side surface on the opposite side, and by doing so, they can be stabilized, and their positioning and paralleling can be easily performed, and The gap between the left and right caps 5 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.

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 slope, and the side plate 14 is bent at a right angle to the top plate 12, so that the back of the ridge 6 is ventilated. Spacer 1
0 and both the upper surface plate portion 12 and the side surface plate portion 14, and the locking projection 6 d of the ridge 6 is attached to the side surface plate portion 1.
4 is locked to the outer edge of the lower end. Then, while the ridge 6 is in contact with the ventilation spacer 10 in this manner, the nail 9 is driven into the shade 5 from the side cover plate portion of the ridge 6. Thereby, the ridge 6 is fixed, and the assembling of each part is completed. In this case as well, if a through hole or a concave portion is formed in advance in the ridge 6 as necessary, 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 this embodiment constructed as described above, the ventilation spacer 10 is interposed between the cap 5 and the sheet metal ridge 6 so that ventilation is provided between them. A gap that becomes a ventilation passage R corresponding to the protruding height of the plate-shaped protrusions 16 and 17 protruding from the upper surface plate portion 12 and the side surface plate portion 14 of the spacer 10 is secured. That is, in this example, the ridge 6 is separated from the coping 5 by the plate-shaped projections 16 and 17 of the ventilation spacer 10, and as shown by the arrow P in FIG. The gap formed between the lower end portion and the roof tile 3 is used as an entrance and exit, between the side surface on the opposite side of the juxtaposed shade 5 and the horizontal covering plate portion 6b of the ridge 6 and the upper surface of the shade 5 The space formed between the upper cover plate portion 6a of the ridge 6 is a ventilation passage R, and the ventilation passage R, the ventilation opening 20 formed at the center of the ventilation spacer 10, and the ventilation passage R described above. Ventilation in the house is performed through the ventilation gap S.

In this case, since the plate-like projections 16 and 17 projecting from the ventilation spacer 10 are structured to support the ridge 6, the ventilation spacer 10 is
The top of the cap 5 and the side opposite to the opposite side and the upper cover plate 6a of the ridge 6
In addition to securing a gap serving as a ventilation passage R between the ridge and the horizontal covering plate portion 6b, the ridge also prevents the inward bending or bending of the ridge packet 6 and lowers the left and right lower ends of the ridge packet 6 with the upper surface of the roof tile 3. Also serves to keep them away from Thereby, the ventilation passage R
Is reliably prevented, and the necessary and sufficient ventilation capacity can be stably maintained.

Further, since both the ventilation spacer 10 and the ridge 6 can be bent or bent, the width of the roof slope that can be accommodated is widened, and the versatility of the ventilation spacer 10 and the ridge 6 is enhanced. Flexible for 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, the Kasagi is less likely to decay, thereby improving the overall durability.

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.

As shown in FIGS. 4 and 5, if a waterproof rib 22 having a height lower than that of the plate-like convex portion 16 protrudes around the ventilation opening portion 20 so as to go therearound, Ventilation spacer 10 and ridge packet 6 without impairing ventilation function
Can reliably prevent rainwater from entering between the house and the house. In the above-described example, the plate-shaped protrusions 16 and 17 are provided in parallel with each other along the front-back direction of the upper surface plate 12 and the side surface plate 14. 1
4 may be provided in parallel with each other along the width direction and at appropriate intervals in the front-rear direction, in which case the house of rainwater that has entered between the ventilation spacer 10 and the ridge 6 It can also be prevented from proceeding indoors by the projection.

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 4 described above are denoted by the same reference numerals, including the entirety, and the description thereof will be repeated, and the description of the common portion of the operational effects Is omitted. As shown in FIGS. 8 and 9, the ventilation spacer 10 used in the example shown in FIG.
A support protrusion 19 is provided, which is bent outward at a right angle from a lower end of the plate-like protrusion 17 protruding from the support protrusion 19.

As shown in FIG. 7, a lower end cover plate 6c formed on the ridge 6 and bent outward from the lower end of the horizontal cover plate 6b is mounted on the bearing protrusion 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. In this way, even if the lower end of the left and right ends of the ventilation spacer 10 comes into contact with the roof tile 3 even if the cap 5 or the like is shifted or tilted from an appropriate position, the ridge 6 The left and right lower ends (locking projections 6d) are reliably separated from the roof tile 3 by the support projections 19, so that a ventilation passage is always provided between the left and right lower ends of the ridge 6 and the roof tile 3. A gap serving as an entrance / exit of R is secured, and ventilation is performed through the gap in the same manner as in the ventilation building structure shown in FIG. 2 described above. The ventilation spacer 1 shown in FIG.
The left and right lower ends of the zeros are separated from the roof tile 3, but it is not always necessary to separate them, and a structure in which the left and right lower ends of the ventilation spacer 10 abut on the roof tile 3 in advance may be used. An opening serving as an entrance and exit of the ventilation passage R is secured on the lateral side of the left and right side plate portions 14 by the support protrusion 19, so that no support is provided.
