Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation structure for an attic of a snowless roof, which is applied to a cold district specification house.

[0002]

2. Description of the Related Art FIG. 5 is a view showing a conventional ventilation structure for an attic of a snowless roof.

In a cold district specification house, as shown in the figure, a roof panel 12 is provided on an outer wall 200 defining the house.
0 through the bonding material 112a having an inclined upper surface,
It is installed so that it descends and leans toward the center of the building. Also,
Bonding materials 112b and 112c having inclined surfaces are also attached to the side end surfaces and the upper surface end portions of the roof panel 120, and the building outer surface of the bonding material 112b is flush with the outer surface of the outer wall 200, and the upper portion of the bonding material 112c. The parapet panel 1
10 are erected.

A parapet cover 114 is covered on the parapet panel 110.

Thus, the roof panel 120 and the parapet panel 110 covered with the parapet cover 114 form a snow-free roof 100.

Since the snow-free roof 100 has a shape that descends and inclines toward the center of the building, it guides the snowmelt water of the snow accumulated on the roof panel 120 to the central valley, and the snowmelt gutter 122 and the vertical direction arranged below the valley. The snowmelt water can be drained to the underground drain by way of the gutter 124.

Below the snowless roof 100,
A ceiling 202 supported by the outer wall 200 and covered with a heat insulating material 204 is attached to define an attic 210.

This attic 210 is provided with an outer wall 200 from all sides.
Since it is hermetically sealed with the parapet panel 110 and hermetically sealed with the roof panel 120 and the ceiling 202 from above and below, ventilation is required.

Therefore, as shown in FIG.
A plurality of holes 206 were bored in 0, a ventilator 220 was attached to each hole 206, and ventilation was performed inside the attic 210 through the ventilator 220.

[0010]

However, the above-mentioned conventional ventilation structure for the attic of the snowless roof has the following problems.

In order to reliably ventilate the attic 210, it is necessary to take a large sum of the opening areas of the holes 206 formed in the outer wall 200.

To this end, the opening area of the hole 206 itself is increased, or the hole 206 having a small opening area is formed on the outer wall 200.
Many holes must be drilled.

However, the large holes 206 are provided in the outer wall 20.
When it is worn as 0, the outer wall 200 that supports the heavy snow-free roof 100 underneath becomes structurally weak, and the durability of the outer wall 200 deteriorates.

Further, it is difficult to attach an exterior material (not shown) to the wall panel 200 and to form the hole 206 therein when the exterior material is a hard material such as concrete or tile.

Moreover, it is necessary to form a plurality of the holes 206 and attach the ventilator 220 to each of the holes 206, which is a complicated work, and moreover, it is necessary to seal the outer circumference of each ventilator 220. Is troublesome, and the on-site work becomes complicated.

Further, since the ventilator 220 must be attached to the outer wall 200 due to the structure of the house,
The drilling position of the ventilation hole 206 was inevitably lowered, and therefore, sufficient ventilation efficiency could not be obtained.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to maintain the durability of the outer wall and reduce the work, and further, to improve the appearance and ventilation efficiency of the house. It is to provide a ventilation structure for the attic with a snow-free roof to improve the above.

[0018]

In order to achieve the above object, the ventilation structure of the attic of a snowless roof according to claim 1 is hollow by being attached to both sides of a core material framed in a rectangular shape. A roof having a substantially V-shaped cross section, which includes a parapet panel that is provided as an interior and is erected on the upper end surface of the outer wall of the building, and a plurality of roof panels that are installed by being inclined downward from the pair of opposing parapet panels toward the center of the building. A ventilation structure for an attic of a snow-free roof including a roof part and a gutter attached to a valley part having a substantially V-shaped cross section of the roof part, wherein the parapet panel includes an upper core material and a surface inside the building. Below the end mounting position of the roof panel in the material, having a communication hole,
The parapet cover is attached to the upper end surface of the parapet panel via a binding material at a position that covers the upper side of the parapet panel and forms a space between the upper end surface and the upper both side surfaces of the parapet panel. A space formed between the parapet cover and the parapet panel, and a communication part formed between the parapet cover and the upper end surface and both upper side surfaces of the parapet panel, the space being formed between the parapet cover and the parapet panel. A communicating portion formed by the bonding material, the communicating hole formed in an upper core material of the parapet panel, a hollow inside of the parapet panel, and the face material inside a building of the parapet panel. It is characterized in that a duct is formed by the communication hole.

[0019]

In the present invention having the above-mentioned structure, since the parapet is provided with the ventilation path, it is not necessary to form any hole in the outer wall which supports the heavy snow-free roof underneath, and the durability of the outer wall is maintained. can do.

Further, since it is not necessary to provide a hole in the outer wall and a ventilator or the like is not attached, the appearance of the outer wall is improved and the appearance of the house is improved.

Furthermore, since laborious work such as hole drilling work, ventilator mounting work, and exterior seal processing work is not required, it is possible to save on-site work.

Further, the air in the back of the hut flows into the panel hollow portion through the communication hole of the parapet panel above the outer wall, rises in the panel hollow portion, and is provided in the upper core material portion of the core material. It flows out from the air outlet between the pair of shield plates. Then, discharged from the gap formed at the upper end of the shielding plate to the outside of the house through the gap between the front or rear surface of the parapet cover and the front or rear material of the parapet panel,
The attic is ventilated. That is, since the ventilation path is set above the ventilation position of the ventilation structure to which the parapet of the conventional snow-free roof described above is applied, the ventilation efficiency is improved.

Moreover, the outside air enters one of the gaps at the upper end of the shield plate from one gap that opens to the outside, passes through above the air discharge port, and opens to the outside through the other gap at the upper end of the shield plate. Since it flows out from the gap, the pressure on the air outlet side becomes negative. As a result, the air in the hollow portion of the panel is efficiently sucked from the air outlet, so that the ventilation hole ratio is further improved.

As described above, by applying the parapet 4 of the present embodiment, the communication hole 10a of the parapet panel 10, the panel hollow portion 14, and the snowless roof 1 on the upper side of the attic 2 are provided.
A ventilation path is formed by the air discharge port 10b and the gaps 71 to 74.

Therefore, since it is not necessary to form a hole for the ventilation path in the outer wall 80 that supports the heavy snow-free roof 1 below, the durability of the outer wall 80 as a structural material can be maintained. At the same time, the appearance of the entire house can be improved.

Further, since the complicated work such as the work for installing the ventilator and the work for sealing the exterior is not required, it is possible to save labor in the field work.

Next, the ventilation function of the attic of the snowless roof to which the parapet of this embodiment is applied will be described.

As shown in FIG. 4, the air D containing moisture in the attic 2 is warmed by the hot air in the room 3 and rises as indicated by the arrow, and the parapet panel 10 is connected to the communication hole 10a through the panel hollow portion. It flows into 14.

Air D that has entered the panel hollow portion 14
Rises in the panel hollow portion 14 as shown in FIG.
It flows out from the air outlet 10b. Then, the air D rises from the upper end openings of the upright portions 43, 47 of the front and rear shielding plates 41, 45 toward the reinforcing plate 55, passes through the pair of gaps 71, 72 opening in the front-rear direction, and reaches the front of the house. And discharged from the gaps 73 and 74 opening to the outside of the rear.

As described above, since the air D in the attic 2 which is warmed and rising is discharged to the outside through the ventilation path formed in the snowless roof 1 above, the damp in the attic 2 is wet. Most of the air D is ventilated, and the ventilation efficiency is improved compared to the conventional ventilation structure of the attic with no snowfall roof.

The outside air E blown into the gap 71 through the gap 73 passes above the upright portions 43 and 47 of the front and rear shield plates 41 and 45, as shown by the two-dot chain line, and passes from the gap 72 to the gap. It goes out through 74.

As a result, the upper side of the air discharge port 10b becomes a negative pressure state with respect to the panel hollow portion 14, and the panel hollow portion 1
Air D in 4 is sucked from the air outlet 10b.

Therefore, from the back of the hut 2 to the hollow part 1 of the panel.
The air D that has flowed into the inside 4 is immediately pulled toward the air discharge port 10b, flows out from the air discharge port 10b, and is discharged to the outside through the gaps 72 and 74 together with the outside air.

In this way, the gap 71 above the parapet 4 is formed.
Since the air inside the panel hollow portion 14 is exhausted by utilizing the ventilation force of the outside air that blows through the space 74, the ventilation efficiency of the air inside the attic 2 is further improved.

The present invention is not limited to the above embodiments, but various modifications can be made within the scope of the invention.

For example, in the above embodiment, the plate piece 60 is used.
The communicating portions are formed by arranging at intervals. However, the present invention is not limited to this, and notches are formed in the upright portions 43 and 47 of the front and rear shield plates 41 and 45 to form the upright portions. Parapet cover 50 on top of 43, 47
It may be attached to.

Further, in this embodiment, the front and rear shield plates 41 and 45, the parapet cover 50, and the support members 58 and 59.
Although and are made of metal, the present invention is not limited to this, and these members may be made of corrosion-resistant plastic or the like.
