DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology of a ventilation structure in a house.

[0002]

2. Description of the Related Art Conventionally, ventilation windows and scabs are provided on the outer wall of a building to allow air to flow between an indoor space and an outdoor space by natural circulation of air. In addition, in the construction of a house, the internal structure of the house such as a floor plan may be determined according to a request of a resident. In such a house design stage, a ventilation structure is taken into consideration. In some cases, it is difficult to configure a sufficient ventilation mechanism in a natural state, and a room may be formed. Since a natural flow of air cannot be formed, air tends to stagnate. Therefore, there are some houses that are equipped with an indoor fan on the ceiling of a room or provided with a skylight to create a flow of air.

Next, embodiments of the present invention will be described. FIG. 1 is a side view showing an entire configuration of a house to which a ventilation structure according to the present invention is applied, and FIG. 2 is a side sectional view of the same. 3 is a plan view, FIG. 4 is a side sectional view showing the structure of the roof of the bookstore, and FIG. 5 is a side sectional view showing the structure of the roof of the half roof hut.

FIG. 1 shows a detached house 1 to which a ventilation structure according to the present invention is applied as an example. The house 1
Is composed of a two-storey bookstore 2 and a separate building 10, and a semi-rooftop hut 3 located above the bookstore 2 and having an attic inside.

As shown in FIGS. 2 and 3, the bookstore 2 and the separate building 10 have a two-story structure having a first floor and a second floor, respectively.
A separate building 10 is constructed at a position via the balcony 4 with respect to the bookstore 2, and one large land roof 5 extending over the bookstore 2 and the separate building 10 is provided. The first and second floors of the bookstore 2 are designed to have substantially the same shape in plan view, and no roof is provided between the first and second floors. However, in some cases, for example, a space protruding from a structure such as the second floor or the balcony 4 is used as a roof or an eave is provided to secure rain and sun protection on the first floor. I have.

A stairwell 9 is formed above the balcony 4 of the flat roof 5 to provide ventilation and solar radiation to the opening facing the balcony 4 and the balcony 4. The flat roof 5 is a separate building 10 located south of the balcony 4
The roof of the house 1 has a neat shape and the construction is simple, and the construction is simple, and the cost is improved while the design is excellent. It can be kept low.

As shown in FIG. 4, a nose house 50 is provided on the upper part of the beam 15 made of I-shaped steel of the book house 2 constituting the flat roof 5.
, And a roof base 51 made of a lightweight concrete material serving as a basis for the roofing materials 6, 6,... The roof base 51 includes a beam 52 that supports the semi-roof hut 3 and a bookstore 2.
Is a flat plate that is installed substantially horizontally between the beams 15 located at the peripheral edge of the
.. Are supported.

On the roof base 51, a heat insulating material 53 having a gradient is placed and fixed. The gradient formed on the heat insulating material 53 is a vertical gradient of the flat roof 5, and is slightly lowered toward the outer periphery of the house 1. On the heat insulating material 53, a roof surface material 55 is stuck via a non-combustible plate 54. Therefore, the roof is constituted by layers in the order of the roof surface material 55 → the non-combustible plate 54 → the heat insulating material 53 → the roof base 51 from the top.

On the other hand, a ceiling plate 59 is attached via a suspension member 58 below the beam 15 fixed to the lower part of the roof at appropriate intervals. A particle board 61 is interposed between a ceiling base 60 placed substantially horizontally on a fixing piece fixed in a shape protruding from the lower part of the beam 15 to the inside of the building, and the ceiling board 59, and a ceiling base 60 is further provided. The heat insulating material 62 is also placed on the upper surface, and the heat insulating material 62 → the ceiling base 60 from above.
The ceiling is configured by forming layers in the order of → particle board 61 → ceiling plate 59 to ensure heat insulation.

As described above, a nose pavilion 50 is supported and fixed above the beam 15 on the outer side of the beam 15 provided on the periphery of the bookstore 2. Eaves roof 6
The upper end of the eaves 3 is supported, and a small turning along the slope of the eaves 64 is formed in the nose purlin 50. An eaves beam 66 is supported from the lower end of the beam 15 via a fixing plate 65. The eaves beam 66 protrudes toward the outside of the building and supports a joist 67 in the middle thereof. Hidden plate 6

Thus, the eaves roof 63 provided in a continuous shape from the land roof 5 is supported. At the lowermost part of the eaves roof 63, a drainer 69 is provided. Parapets are often formed on the periphery of the roof in the case of a normal flat roof, but as described above, the roof according to the present invention has the eaves 64 formed on the flat roof 5. Therefore, by having the eaves 64 in spite of the flat roof 5, it is possible to prevent the wind and rain from directly hitting the wall 70 of the house 1 or to shield sunlight. Further, the eaves roof 63 is provided with a slope different from the roof, that is, the eaves roof 6
The roof 3 has a slope larger than that of the flat roof 5 so that the eaves can be seen thinner in a side view, so that the roof has a sharp and light luxury.

[0016] In recent years, a space in which ventilation between the inside of the house and the outdoor space 18 is hindered may be formed as the house becomes more airtight. In these spaces, it is difficult to form a natural flow of air, so that air tends to stagnate.

In the house 1 according to this embodiment, an atrium 16 is formed between the first floor and the second floor at a substantially central portion in plan view of the bookstore 2 to promote ventilation. Therefore, an air flow path is formed so that the air flow on the first floor enters the room through an opening such as a window or an entrance on the first floor, and passes upward through the blow-through 16. As described above, the atrium 16 is provided substantially at the center of the building so that the air on the first floor flows upward without staying on the first floor, so that the flow of air is easily generated. The position of the atrium 16 is not limited to substantially the center of the bookstore 2 in plan view, but is preferably changed as appropriate according to the condition of the land where the house 1 was built, for example, the direction of the wind and the surrounding buildings. .

The air that has entered the second floor from the opening on the second floor of the bookstore 2 or through the stairwell 16 on the first floor flows further upward to the semi-roof hut 3 located above the bookstore 2. Reach. Although the opening of the house 1 is provided with a large window and is designed to sufficiently consider the traffic of air,
The air flow tends to be stagnant toward the inside of the building.
6 is provided, and an opening through which air can flow is formed between the second floor of the bookstore 2 and the half-roof hut 3 above the atrium 16 so that a gentle upward flow of air can be made as natural as possible. Make up.

The air that has reached the half-roof hut 3 is discharged to the outdoor space 18 by a ventilation mechanism 14 provided above the slope of the sloping roof 12 formed in the half-roof hut 3. Therefore, the air in the house 1 is configured to flow upward and out of the house 1 in a consistent manner, so that a natural air flow is constantly formed as much as possible.

The semi-roof hut 3 formed above the bookstore 2 is provided as an air-conditioning machine room of the house 1, but may also be used as a storeroom or a hobby room. The semi-roofed hut 3 has a one-way sloped roof 12. A ventilation mechanism 14 described below is provided above the slope of the sloped roof 12 to promote ventilation of the bookstore 2. In the present embodiment, the shape of the roof of the semi-roofed hut 3 is a one-sided sloped roof, but the shape of the roof is not limited to this embodiment, and may be a land roof or a gable roof. I do not care.

As shown in FIGS. 4 and 5, the wall 24 of the semi-roof hut 3 having a substantially rectangular shape in a plan view is supported substantially vertically on the roof base 51 of the land roof 5, and At the joint 71 between the flat roof 5 and the wall 24, a water treatment (not shown) is performed. The beam 19 that supports the sloped roof 12 via the pillar 72 is located above the beam 52 that supports the flat roof 5.
A roof beam 23 of the sloped roof 12 is erected above these beams 19. The roof beam 23 is a semi-roof hut 3
It has a slope that descends almost south because it forms the basis of the slope that is formed on the roof. Above the slope of the roof beam 23, ie
The north and south ends of the roof beam 23 are larger than the wall 24 and protrude outside the building.

As shown in FIG. 5, the ventilation mechanism 14 is provided above the sloping roof 12 of the half-roof hut 3, that is, at the north end. In the half-roof hut 3, a ceiling plate 21 supported via a suspension member 20 on a beam 19 placed on a beam 52 located on the second-floor ceiling of the bookstore 2 via a column 72.
And a slanted beam 22 supported by a fixing piece similarly fixed to the upper part of the beam 19, forming a ceiling on the indoor space 17 side of the half-roofed hut 3 via a heat insulating material.

A roof beam 23 is supported above the inclined beam 22. The roof beams 23 are arranged with the same gradient as the inclined beams 22 and form the basis of the gradient roof 12. The upper part of the roof beam 23 projects sideways from the outer wall 24 of the half rooftop hut 3 to form an eave 25. At the upper end of the roof beam 23, a nose plate 26 is fixed, and further, an eave decorative panel 28 is attached along the eave via an eave decorative panel support piece 27, thereby improving the beauty of the eaves of the half rooftop hut 3. Has contributed. An eaves ceiling plate support piece 29 extends below the eaves decorative board support piece 27 that supports the eaves decorative board 28,
An eave ceiling plate 31 is erected between the eaves and the back eaves 30 fixed to the outer wall 24 of the half roof hut 3. The eave ceiling plate 31 is a plate-like member made of a lightweight metal material such as an aluminum composite member and has excellent corrosion resistance, so that no load is applied to the roof beam 23 and the outer wall 24.

A purlin 32 is appropriately arranged on the roof beam 23 in a direction orthogonal to the roof beam 23. The purlin 32 is made of hollow steel having a rectangular cross section, and is supported and fixed to the roof beam 23 by angle steel. Then, a roof material 33 is stuck and fixed on the main house 32.

A ventilation duct 40 is provided from the ceiling of the semi-roof hut 3 configured as described above to the upper part of the sloping roof 12, and the ventilation mechanism 14 is configured. The indoor side ventilation opening 40a of the ventilation duct 40 is connected to the ceiling plate 2 of the half rooftop hut 3.
1, the ventilation duct 40 penetrates through the ceiling plate 21.

The ventilation duct 40 extends upward from the ceiling of the half-roof hut 3 and, when it reaches the roof, is bent and extends outward from the outer wall 24 along the roof beam 23. The ventilation duct 40 passes above the eave ceiling plate 31 outside the outer wall 24 and forms an outdoor ventilation port 40b that goes upward above the roof beam 23.
In this manner, the ventilation duct 40 is concealed by the ceiling plate 21 on the indoor space 17 side and the eave ceiling plate 31 on the outdoor space 18 side, and its duct is provided so as not to be exposed from the exterior of the house 1.

In the ventilation mechanism 14 configured as described above,
The air in the indoor space 17 flows into the ventilation duct 40 from the indoor ventilation port 40a and is discharged from the outdoor ventilation port 40b to the outdoor space 18 (45a and 45b). At this time,
Since the air flow is configured to go upward,
It has a structure where air flows easily and naturally.

In the ventilation duct 40, an electric fan 41 is provided just above the ceiling plate 21. The fan 41 does not always operate, but is provided with a sensor for detecting the air flow. When the air flow is very small, the fan 41 operates automatically and the fan 41 automatically operates.
Try to encourage ventilation. Therefore, a comfortable indoor environment can be maintained even in rainy weather or the like.

The position of the semi-roof hut 3 constructed as described above can be relatively freely determined in the upper part of the bookstore 2. As mentioned above, the flat roof 5 is formed in the bookstore 3, but since the flat roof 5 is provided at a slight gradient, the arrangement position of the half roof hut 3 is changed for each individual house 1 at the time of design. Or, even if a sudden change occurs after the design and the arrangement position is changed, the entire roof configuration (for example,
Since there is no significant change in the design of beams, roofing materials, etc., it can be changed relatively easily. Further, even if the location of the semi-roof hut 3 is changed, the aesthetic appearance of the house with the roof is not impaired.

For example, if the roof of the bookstore 2 has a slope structure such as a gable roof, the roof is designed in accordance with the location of the semi-roof hut 3. It is expected that there will be restrictions on the installation location and that the appearance of the roof may be significantly impaired.
In order to change the arrangement position, the members constituting the roof and the like are greatly changed.

In the house 1 employing the ventilation structure according to the present invention, the roof provided on the bookstore 2 serving as the base is a flat roof 5, so that even if the arrangement of the rooms inside the house is changed at the request of the resident, the change is not made. It is possible to easily change the arrangement position of the half-roof hut 3 according to the conditions. Therefore, it is possible to construct the house 1 according to many patterns using the same member, and therefore, it is rich in versatility, that is, contributes to the reduction of the construction cost of the house. And even if the appearance of the house is complicated, a reliable ventilation path can be provided, and a comfortable living space can be constructed.

[0032]

The present invention is configured as described above.
The following effects are obtained.

That is, as set forth in claim 1, the roof of the house is formed as a flat roof, and the semi-roof hut provided with the ventilation mechanism is arranged in a part of the roof. It is possible to easily change the arrangement position of the semi-roof hut according to the arrangement of the rooms, and it is possible to use the same member to accommodate a house according to many patterns, Even if the shape is complicated, a reliable ventilation path can be provided.

In addition, since the semi-roof hut is arranged at the upper part of the room, it is possible to easily evoke a room which is difficult to evoke, and to improve ventilation.
