Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system for a livestock house such as a poultry house, a warehouse, a factory, and other buildings which are relatively inexpensive and easily constructed.

[0002]

2. Description of the Related Art As is well known, in a building, a ventilation device is required to ventilate the internal air. For example, in a general household building, openings such as windows and an air conditioner are installed to ventilate, and in a high-rise building, the entire interior is individually or individually controlled to be ventilated. , Spending a lot of money on ventilation equipment. However, expensive livestock ventilation systems cannot be used in livestock houses such as poultry houses and pig houses, large-scale warehouses and factories, and other buildings that need to be constructed at low cost.

[0003] Therefore, Jikken Sho 6 proposed by the present applicant.
A ventilation device for a building used as a poultry house described in JP-A-3-49634 is known. In the conventional ventilation device for a building described above, the wall surface and the roof surface have a two-layer structure to form a ventilation path communicating from the lower part of the wall surface to the roof
The outside air sucked from the gable wall surface is blown from the ceiling surface to the inside of the building to raise the pressure, and the pressured air is exhausted from the roof ridge through the ventilation passage from the lower portion of the wall surface.

[0004]

However, even in the conventional ventilation device for a building, since the wall surface and the roof have to have a two-layer structure, the building materials are required accordingly, and the work at the time of construction is required. However, it takes time and labor, which increases the construction cost. Moreover, not only does the volume on the indoor side decrease because the wall surface is a two-layer structure, but also the ventilation capacity is limited due to the narrow air passage, and there is sufficient ventilation especially in large-scale buildings. It is not possible to expect an effect.

Therefore, it is possible to propose a structure in which a ventilation port is opened above the wall surface of a building, but due to a phenomenon in the natural world, wind and rain and dust are strongly blown in and direct sunlight is irradiated. Therefore, when the building is a livestock house such as a poultry house or a pig house, it may adversely affect the livestock raised in the house and cause illness or death. In addition, when the building is a warehouse or factory, it may damage or damage the preserved items inside, and cannot be used at all. Therefore, there is a demand for a ventilation device for a building that can be constructed at a very low cost, but has a significantly good ventilation effect in the room, and that the interior of the building is not affected by natural phenomena.

[0006]

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above-mentioned drawbacks and demands of the prior art. Exhaust air that communicates the interior side and the exterior side with the upper part of the wall surface of a building where the inside is lifted up. An opening is formed, and a protective frame body having a bottom surface portion and a side surface portion is provided above the outdoor side of the wall surface so as to cover the outdoor side of the exhaust port, and the upper end of the side surface portion of the protective frame body is provided. The part is extended above the exhaust port and above the eaves end of the roof of the building. And, in the case of a poultry house, it is a windowless building without windows, and because it breeds chickens with artificial lighting inside, it is necessary to block direct sunlight, but in the building of the present invention, the above protection is required. The frame body can reliably shield the outdoor side of the exhaust port from light.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The drawing shows a case where the building 1 of the present invention is used as a poultry house.

On the wall surface 2, horizontal crosspieces 22 are vertically arranged on the outdoor side of pillars 21 standing upright from the foundation of the building at appropriate intervals, and wallboards are provided on the outdoor side of the horizontal crosspieces 22. 23 is watertightly and liquidtightly stretched. Therefore, in the wall surface 2, the wall plate 23 partitions the outdoor side and the indoor side. A heat insulating material may be attached to the inner surface of the wall surface 2.

On the roof 3, purlins 31 are installed at appropriate intervals from the ridge toward the eaves, and rafters 32 are fixed on the top of the purlins 31 so as to be orthogonal to the purses 31.
A roof plate 33 is densely roofed on the upper surface of the rafter 32. Therefore, the roof 3 includes the roof plate 33.
It is also possible to partition the outdoor side from the indoor side and additionally install a heat insulating material on the indoor surface of the roof plate 33.

The wall plate 23 of the wall surface 2 is stretched to the lower surface of the purlin 31 at the eaves tip portion 34 of the roof 3, but is stretched in the range of the heights of the purlin 31 and the rafters 32. Absent. Therefore, between the upper end of the wall plate 23 and the lower surface of the roof plate 33, in the range of the height of the purlin 31 and the rafter 32, the exhaust port 24 that communicates the outdoor side with the indoor side is provided. Is configured. Further, the eaves portion 34 extends from the wall surface 2 to the outside of the room, and a downward draining light-shielding plate 35 is provided at the outdoor end of the eaves portion 34, and a snow stopper is provided on the surface of the roof 3 near the eaves portion 34. A tool 36 is installed.

The ceiling 4 is located below the indoor side of the roof 3, a plurality of air outlets 41 are formed in slits along the length of the building 1, and the roof 3 is provided at the left and right side ends.
Has an inner wall portion 42 that reaches the back surface of the column member 21 and is located on the indoor side of the column member 21. Therefore, a ventilation duct 43 surrounded by the roof 3 on the upper side, the ceiling 4 on the lower side, and the left and right inner wall portions 42 is formed in the ceiling above, and the ventilation duct 43 is constructed by the air blowout port 41. Communicate with the inside 5 of the. Further, the indoor side of the exhaust port 24 is covered by the inner wall portion 42, but communicates with the inside 5 of the building 1 with a space corresponding to the thickness of the pillar 21.

According to the present invention, a protective frame 51 is provided above the outdoor side of the wall surface 2 so as to cover the outdoor side of the exhaust port 24. The protection frame body 51 is provided on the upper portion of each of the column members 21 so as to project to the outside of the room.
L-shaped gutter material 53 is hung over the character-shaped support metal fitting 52,
It is configured by fixing it with bolts or spot welding in the length direction of the wall surface 2.

The gutter material 53 is formed by bending a metal plate material and has a bottom surface portion 54 and a side surface portion 55 provided upright on one side of the bottom surface portion 54. Although 54 is located below the exhaust port 24, the side surface 55
The upper end of the roof 3 is above the exhaust port 24 and
It extends above the eaves tip portion 34 and covers the outdoor side of the exhaust port 24.

As described above, the exhaust port 24 is covered on the outside by the eaves portion 34, the drainage shading plate 35 and the protective frame 51, and on the inside by the inner wall 42 of the ceiling 4. Therefore, even if the direct sunlight of the sun is radiated on the outdoor side, it is blocked by the eaves edge portion 34, the protection frame 51, the inner wall portion 42, etc., so that the interior 5 of the building 1 is not illuminated. Further, for example, even when a strong wind or rain is blown from the side or diagonally in a storm, etc., the eaves tip portion 34, the protective frame 51, the drainage shading plate 35, etc. shut off on the outdoor side and the indoor side on the indoor side. Since the inner wall portion 42 is cut off, the inside 5 can be surely protected from natural phenomena such as wind and rain and sun rays.

The building 1 of the present invention has the above-described structure. For example, the outside air is blown into the inside of the ventilation duct 43 by the fan mechanism 6 provided on the end wall of the building 1, and the outside air is blown from each air outlet 41. When blown into the inside 5 of 1, the inside 5 becomes a lifting pressure. Therefore, the inside air of the inside 5 is the wall 2
Since it rises along the indoor surface of the building 1 and is exhausted to the outside from the exhaust port 24, the interior 5 of the building 1 is efficiently ventilated. When the snow is accumulated, the snow stopper 36 does not cause the snow to slide off the roof, so that the protective frame 51 is not damaged. Further, the protection frame 51 can function as a rain gutter, but it is also possible to cut out a part of its length to let rainwater flow down on the outdoor surface of the wall surface 2.

The present invention has been described above based on the embodiments shown in the drawings. However, the present invention is not limited to the above-mentioned embodiments, and the present invention is not limited to the embodiments described below. But it can be done.

[0017]

In summary, according to the present invention, an exhaust port is formed in an upper part of a wall surface of a building where the inside is a lifting pressure, and an exhaust port communicating between the indoor side and the outdoor side is formed. And a side surface portion to provide a protective frame body that covers the outdoor side of the exhaust port, the upper end portion of the side surface portion of the protective frame body, above the exhaust port, of the roof of the building It is characterized in that it extends upward from the eaves.

Therefore, since the wall and the roof are one layer, the construction material is small, and the construction work is simplified, so that the construction cost can be reduced, and the construction cost of the building can be reduced. Not only can this be done, but the construction time can be significantly shortened. In addition to strong wind and rain from the top, even if there is strong horizontal wind or heavy rain, the outdoor side of the exhaust port is covered by the eaves part, the drainage shading plate, the protective frame body, and the side surface of the protective frame body. Since the upper end of the part is above the exhaust port and extends above the eaves of the roof, it is possible to reliably block not only wind and rain but also direct sunlight. The room can be protected reliably. Further, since the exhaust port is directly opened to the inside of the building, the exhaust capacity is extremely high, and the ventilation efficiency inside the building can be remarkably improved. Therefore, especially in a windowless building with no windows, it is possible to use artificial lighting to prevent sunlight from shining, and to use it as a large-scale poultry house where chickens cannot be raised without adequate ventilation. ,
It is easy to maintain and maintain, can be constructed at low cost in a short time, and has high practical value.
