Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a ventilation structure of a building, and more particularly to a ventilation structure of a building suitable for ventilation of a building having a roof with a snow-free construction method.

<Prior Art> In areas with a large amount of snow, in recent years, wing-shaped roofs of snowless construction have been adopted for the roofs of buildings in order to prevent snowfall on neighboring houses. In such a roof type, a parapet is provided on the edge of the roof panel to prevent snowfall from the edge.

When the roof type with no snowfall construction is adopted, the back surface of the roof panel is easily condensed due to the accumulation of snow on the roof. Therefore, ventilation of the attic facing the back of the roof panel is performed.

As such a ventilation structure, a ventilation port that communicates with the attic is provided on the outer surface of the parapet, and the air in the attic is allowed to flow through the ventilation port to improve the environment inside the attic, and thus to the back of the roof panel, etc. It is known to prevent dew condensation.

On the other hand, especially in areas with a large amount of snow, there are many times when the temperature difference between the outside air and the building is large, so there are walls that are most affected by the temperature inside the building and exterior materials that are attached to the outside surface and exposed to the outside air. Condensation often occurs between the walls, and walls and exterior materials are easily corroded. Therefore, it is also preferable to provide an air passage between the wall and the exterior material to ventilate the back surface of the exterior material from the viewpoint of improving the durability of the building.

<Problems to be solved by the invention> However, in an area with a large amount of snow, a large amount of snow increases the amount of snow hanging from the upper edge of the parapet. Therefore, in the above-described conventional ventilation structure, the ventilation opening provided on the outer side surface of the parapet may be blocked by the snow from the upper edge of the parapet, and the attic may not be ventilated. In order to prevent the ventilation port from being blocked by snow, for example, even if the upper part of the parapet is projected outward from the outer surface of the wall, the snow hanging from the upper edge of the parapet wraps around and the same. There is a problem that the ventilation port is blocked.

Further, even when the ventilation path is provided between the wall and the exterior material, the ventilation path is formed so as to open upward, and therefore the ventilation port may be blocked by snow.

Therefore, it is possible to prevent the ventilation opening of the parapet and the ventilation opening of the ventilation path formed between the wall and the exterior material from being blocked by snow. It is expected to develop a ventilation structure for buildings that can reliably perform the above.

<Means for Solving the Problems> In the ventilation structure for a building according to the present invention, the outside surface of the parapet projecting upward from the edge of the roof panel is connected to the indoor side through the back surface side of the roof panel. There is a ventilation port that communicates. Further, vertical furring strips are interposed at a predetermined interval between the wall and the exterior material attached to the outer surface side of the wall,
A ventilation port of a ventilation path surrounded by the exterior material, the furring strip and the wall is formed in an upper portion between the wall and the exterior material. A ventilation cover is provided so as to hang from the upper end of the parapet to the outer surface side of the parapet and cover the ventilation port and the ventilation port. This ventilation cover is composed of a top plate that covers the upper end surface of the panel, a side plate that hangs from the tip of the top plate approximately parallel to the outer surface of the parapet and the outer surface of the wall that continues to this outer surface, and the side plate. It consists of a bottom plate bent from the lower end toward the exterior material at a substantially right angle, and the side plate of the ventilation cover is arranged at a predetermined distance from the outer surface of the parapet, and between the end of the bottom plate and the exterior material. The outside air port is formed.

<Operation> According to the building ventilation structure of the present invention, the side plate of the ventilation cover hanging from the upper end of the parapet to the outer surface side of the parapet is substantially parallel to the outer surface of the parapet and the outer surface of the wall, and Since the outer surface of the parapet is arranged at a predetermined distance from the outer surface of the parapet, the outer surface of the exterior material attached to the outer surface of the wall and the side plate are also separated by the predetermined distance. Therefore, due to a large amount of snowfall, the snowfall increases from the tip of the top plate of the ventilation cover to the side plates, and even if it goes around to the bottom plate side, the snowfall is formed between the end of the bottom plate and the exterior material. It does not reach the outside air outlet.

Also, since the ventilation port and the ventilation port are covered with the ventilation cover, the inside of the ventilation cover that communicates with the outside through the outside air port and the ventilation port and the ventilation port are in communication with each other. As a result, the ventilation on the indoor side and the ventilation on the back side of the exterior material are performed. Here, as described above, the side surface plate of the ventilation cover is arranged with a predetermined distance from the outer surface of the parapet, so that a large internal space of the ventilation cover is secured, so inside the ventilation cover, Air on the inside of the room that enters through the ventilation port to the outside air, air on the back side of the exterior material that enters through the ventilation port to the outside air, and outside air that enters through the outside air port toward the ventilation port and the ventilation port. The flow of is formed smoothly.

<Embodiment> Hereinafter, a preferred embodiment of a building ventilation structure according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a sectional view showing a ventilation structure of a building according to an embodiment of the present invention.

In this ventilation structure as shown in the figure, the edge of the roof panel 5 is arranged at the upper end of the wall 1. The upper end of the wall 1 extends upward in a state of being assembled with the edge of the roof parapet 5, and is connected to the parapet 6 projecting upward from the edge of the roof panel 5.

A plurality of ventilation passages 7 communicating with the attic on the rear surface side of the roof panel 5 are provided between the rear edge portion of the roof panel 5 and the upper end surface of the wall 1 in the direction of the upper edge of the wall 1. A ventilation port 8 communicating with the ventilation passage 7 is formed on the outer side surface 9 of the parapet 6.

A siding 3 as an exterior material is attached to the outer surface 16 side of the wall 1 via vertical furring strips 2 arranged at a predetermined interval on the outer surface 16. Between the outer surface 16 of the wall 1 and the siding 3 via the vertical furring strip 2, a ventilation passage (not shown) surrounded by these and the vertical furring strip 2 and having a thickness of the vertical furring strip 2 is provided. It is in a state of Further, this ventilation path is opened as a ventilation port 4 of the ventilation path at an upper portion between the siding 3 and the wall 1.

On the other hand, a ventilation cover 11 is provided so as to hang from the upper end of the parapet 6 to the outer surface 9 side of the parapet 6 and cover the ventilation port 8 and the ventilation port 4. The ventilation cover 11 covers the upper end surface 10 of the parapet 6 and has a tip extending outwardly from the outer surface 9 of the parapet 6, and an upper surface 12 of the parapet 6 connected to the outer surface 9 of the parapet 6 from the tip of the upper plate 12. Outer surface of wall 1
16 and a side plate 13 hanging substantially parallel to
The bottom plate 14 is bent from the lower end toward the siding 3 direction. Therefore, the side surface plate 13 is arranged at a predetermined distance from the outer side surface 9 of the parapet 6. Further, an outside air port 15 that connects the inside and outside of the ventilation cover 11 is provided between the end of the bottom plate 14 and the outer surface 17 of the siding 3.

In such a building ventilation structure, a ventilation cover is hung from the upper end of the parapet 6 to the outer surface 9 side of the parapet 6.
The side plates 13 of 11 are the outer surface 9 of the parapet 6 and the outer surface of the wall 1.
Since they are arranged substantially parallel to 16 and at a predetermined distance from the outer side surface 9, the outer surface 17 on the upper end side of the siding 3 attached to the outer surface 16 side of the wall 1 and the side plate. 13
In both cases, they are separated by the above-mentioned predetermined interval. Therefore, due to a large amount of snow accumulated, the snow increases from the tip of the upper surface plate 12 of the ventilation cover 11 to the side surface plate 13, and even if the snow falls around the bottom plate 14 side, the snow cover is formed on the siding 3 side. Since it does not reach 15, it is possible to prevent the outside air port 15 from being blocked by snow.

Further, since the ventilation port 8 on the outer side surface 9 of the parapet 6 and the ventilation port 4 of the ventilation path formed on the back surface side of the siding 3 are covered with the ventilation cover 11,
The interior of the ventilation cover 11 is communicated with the inside of the interior of the siding 3 and the inside of the ventilation cover 11 is ventilated. Here, as described above, the side plate 13 of the ventilation cover 11 is arranged at a predetermined distance from the outer side surface 9 of the parapet 6, so that a large internal space of the ventilation cover 11 is secured. Therefore, inside the ventilation cover 11, the air on the indoor side that enters through the ventilation port 8 to the outside air port 15, the air on the back side of the siding 3 that enters the outside air port 15 through the ventilation port 4, and the outside air port 15 It is possible to smoothly form the flow with the outside air that goes toward the ventilation port 8 and the ventilation port 4 via the.

Therefore, according to the ventilation structure for a building of the present embodiment, it is possible to prevent the ventilation port 8 and the ventilation port 4 from being blocked by snow, so that it is possible to reliably perform ventilation on the indoor side and on the back side of the siding 3. Since the flow of air for ventilation and ventilation can be formed smoothly inside the ventilation cover 11, ventilation and ventilation can be performed efficiently.

<Effect of the Invention> As described above, according to the building ventilation structure of the present invention, the side plate of the ventilation cover is substantially parallel to the outer surface of the parapet and the outer surface of the wall continuous with the parapet, and Since the outer surface of the parapet is arranged at a predetermined distance from the outer surface of the parapet, the outer surface of the exterior material and the side plate are also separated by the predetermined distance described above. Even if the snow increases from the side plate toward the bottom plate, the snow does not reach the outside air port formed between the exterior material and the bottom plate.
Therefore, it is possible to prevent the outside air port from being blocked by snow, so that it is possible to reliably perform ventilation on the indoor side and ventilation on the rear surface side of the exterior material.

In addition, since the ventilation port on the outer side of the parapet and the ventilation port formed on the back side of the exterior material are covered by the ventilation cover, the ventilation port and the outside can be ventilated through the inside and outside air ports of the ventilation cover. It is possible to establish communication with the mouth. At this time, as described above, since the side plate of the ventilation cover is arranged at a predetermined distance from the outer surface of the parapet, it is possible to secure a large internal space of the ventilation cover. It is possible to smoothly form a flow of air that ventilates the indoor side through the outside air port and a flow of air that vents the back surface side of the exterior material through the ventilation port and the outside air port. Therefore, the ventilation on the indoor side and the ventilation on the back side of the exterior material can be efficiently performed.
