Description

The present invention relates to a house provided with a ventilation system using large black pillars throughout the building structure. In particular, the present invention relates to a structure applied to a house where a large black pillar is erected.
In the present invention, the term “house” is based on an individual residence, a so-called single house, but also includes a small apartment house. There are various types of houses such as wooden and reinforced concrete.

Traditional Japanese houses were made of wood and had a rim, and many of them were partitioned with shoji and bran.
However, in recent years, houses by a panel method that are assembled and manufactured using wall panels, floor panels, roof panels and the like that have been manufactured in advance in factories or the like for the purpose of aesthetics and low-cost construction have become widespread. Such a house improves the hermeticity of the house as compared to the conventional construction method. This airtightness is a problem. Especially in cold regions, the heating frequency is high in winter and improvement in ventilation performance is desired.
For this reason, for example, as shown in FIG. 18, in order to promote ventilation in the room, a “ventilation gallery” for natural ventilation is provided on the partition wall in the house. In addition, in order to finally exhaust the air to the outside air, it is necessary to attach a “ventilation gallery” to the outer wall at the same time.

  As shown in FIG. 19, the ventilation gallery is provided in the openings Da, Db, Dd and the like of the wall and is used as a ventilation hole or a ventilation hole, and includes a forced ventilation device provided in the vicinity of the roof. Although air is flowed between the rooms through the ventilation gallery and exhaust and intake are performed from a part of the outer wall, the air flow is not ensured as it is. Therefore, the forced ventilation device is an indispensable configuration of the ventilation louver. Air is ventilated between the rooms by the intake / exhaust capacity of the forced ventilation device, and ventilation is performed between the outside air (Japanese Patent Laid-Open Nos. 2002-266655, 2002-266433, and 2002-22221). (Publication etc.)

  As another ventilation method, a ventilation system using a forced ventilation device using a radiator as shown in FIG. 20 is also known. This ventilation system uses electrical energy, etc., to heat the air under the floor with a radiator and circulate the air, and to ventilate the entire room by securing a passage for the air circulated indoors (special No. 2002-194427).

JP 2002-266565 A JP 2002-266433 A JP 2002-022211 A JP 2002-194427 A JP 2002-227316 A

It is considered that a certain degree of ventilation is possible in a house that employs the conventional ventilation system. However, there are the following problems.
In the case of a house that employs a ventilation system using a ventilation gallery, a first problem is that a forced ventilation device needs to be provided in each ventilation gallery, which increases costs. In addition to the cost of forced ventilation, ventilation is always performed while consuming electricity, so running costs are incurred and it is difficult to save power. As a second problem, since the forced ventilation device involves rotation of the fan, noise may be a concern.

Next, in the case of a house that employs a ventilation system that uses a radiator, the first problem is that the cost is high. Since ventilation is always performed while consuming electricity, running costs are incurred and it is difficult to save power. As a second problem, while the heat island phenomenon in the city is progressing, it is necessary to lower the temperature of the house when it is hot in summer, and a house that is easy to spend even in an environment without using an air conditioner is required. There is a problem that it cannot be used in spring or autumn as well as hot in summer.
Some conventional techniques aim to ventilate with natural force without using a forced ventilation device (Japanese Patent Laid-Open No. 2002-227316, etc.), but the force for circulating air (ventilation capacity) is inadequate. Insufficient ventilation was not possible because it was sufficient.

  In view of the above problems, an object of the present invention is to provide a house provided with a ventilation system using a large black pillar capable of exhibiting high outside air and indoor ventilation capacity without using a forced ventilation device or the like. .

In order to achieve the above object, a house equipped with a ventilation system using a large black pillar of the present invention is
A foundation layer, a foundation layer provided on the foundation layer and a foundation layer having an underfloor space, a large black pillar penetrating from the foundation layer to the second floor beam, and an attic cylinder penetrating to the upper end of the large pillar and the roof; With
The interior of the large black pillar is a cavity, and a flow of air blown from the underfloor space of the foundation layer onto the roof is created in the cavity of the large black pillar, and the space of the foundation layer and the cavity of the large black pillar are formed on the side of the large black pillar. A foundation vent hole to be connected, a vent hole for guiding air from the hollow of the large pillar to the house, and a vent hole for guiding air from the house to the hollow of the large pillar are provided to ventilate and ventilate the house using the large pillar. It is characterized by that.
With the above configuration, a large black pillar penetrates from the foundation layer to the roof, and a flow of air that blows from the foundation layer space onto the roof can be created in the cavity of the large pillar due to the temperature difference between the foundation layer and the roof. The air flow in the house can be controlled by providing a ventilation hole and a ventilation hole that conduct to the house on the side surface.

The house provided with the ventilation system using the large black pillar of the present invention can also control the air flow by providing a plurality of large black pillar cavities as follows.
That is, a foundation layer, a foundation provided on the foundation layer and a foundation layer having an underfloor space, a large black pillar penetrating from the foundation layer to the second floor beam, and an attic cylinder penetrating to the upper end of the large pillar and the roof. With body,
A plurality of cavities penetrating in the vertical direction are provided inside the large black pillar, and among the plurality of cavities, a blocking wall is provided in the vicinity of the ceiling on the first floor, and conduction in the vertical direction is closed in the vicinity of the ceiling on the first floor. A hollow is provided in the vicinity of the ceiling of the second floor, and a barrier is provided in the vicinity of the ceiling of the second floor to block conduction in the vertical direction as a second cavity, and those that are conducted to the roof are the third and fourth cavities. age,
On the side of the large black pillar,
A foundation vent connecting the space of the foundation layer and each of the cavities;
In the beam between the first-floor ceiling and the second-floor floor, the first-floor vent that connects the first-floor space and the first cavity and guides air from the foundation layer space to the first-floor space;
In the beam between the second-floor ceiling and the attic, the second-floor vent that connects the second-floor space and the second cavity and guides air from the base layer space to the second-floor space;
In the beam between the first-floor ceiling and the second-floor floor, the first-floor ventilation hole that connects the first-floor space and the third cavity and guides air from the first-floor space to the roof;
A beam between a second-floor ceiling and the attic is provided with a second-floor ventilation hole that connects the second-floor space and the fourth cavity and guides air from the second-floor space to the roof, and the air flow is It is built inside, and it is characterized by ventilating and ventilating the house using large black pillars.

  In addition, in the ventilation system using the large black pillars, it is possible to give the large black pillars a seismic isolation structure by injecting rubber around the large black pillars in the foundation layer, and to improve the structural strength of the entire house. Become.

  Further, in the ventilation system using the large black pillar according to the present invention, a small space that can be filled with an air improving agent is provided on the wall surface adjacent to the large black pillar, and an air inlet hole and an upper portion are disposed on the side of the large black pillar near the lower portion of the small space. If an air exhaust hole is provided, and ventilation and ventilation of the house is performed by air improved by the air improver by the air flow in the large black pillar, it is possible to combine measures to improve the air. The living environment is improved.

  Next, the ease of construction can also be considered. When a large black pillar is used, the construction tends to be difficult due to its weight. If the large black pillar is formed by collecting a plurality of hollow pillars inside, the construction of the large black pillar becomes easy. Moreover, when gathering a plurality, it is also preferable to sandwich a cushioning material between them. This is because it is possible to prevent a squeak noise caused by rubbing even if the pillars expand and contract due to changes in the temperature of the day.

  Next, in order to increase the momentum of the air flow in the large black pillar, it is possible to use the action of the wind flowing on the roof. In the case of a configuration utilizing the action of wind, for example, a roof having a casing that is bent so that the lower end is in the downward direction and the upper end in the horizontal direction is rotatable in the circumferential direction of the column axis. The rotating cylinder may be rotated so that the upper end of the rotating cylinder is positioned leeward, provided above the large black pillar. Since the upper end opening of the rotating cylinder is located on the leeward side, the air flow in the rotating cylinder decreases due to the flow of the wind, and the effect of sucking up air from the inside of the large black pillar can be obtained.

  In addition, when a rotating cylinder is provided above the large black pillar, it is preferable to devise so that rainwater does not flow into the rotating cylinder and the large black pillar. For example, if a water return to prevent water from flowing in from the upper end of the rotating cylinder and a drain hole for allowing water to escape outside the rotating cylinder are provided near the upper end of the rotating cylinder, the inflow of rainwater Can be prevented.

According to the house having the ventilation system using the large black pillar of the present invention, the large black pillar penetrates from the foundation layer to the roof, and the temperature difference between the foundation layer and the roof causes the large black pillar to enter the cavity from the foundation layer to the roof. The air flow in the house can be controlled by providing a ventilation hole and a ventilation hole that conduct to the house on the side of the large black pillar.
In addition, according to the house provided with the ventilation system using the large black pillar of the present invention, it is possible to use the action of the wind flowing on the roof in order to increase the momentum of the air flow in the large black pillar. Thus, the effect of lowering the air pressure inside the rotating cylinder and sucking air from the inside of the large black pillar can be obtained.
Moreover, according to the house provided with the ventilation system using the large black pillar of the present invention, it is possible to give the large black pillar a seismic isolation structure by injecting rubber around the large black pillar in the foundation layer. Strength can be improved.

  Hereinafter, the best mode for carrying out the present invention will be described specifically by way of examples. The present invention is not limited to these examples.

  A two-story house will be described as an example of a house provided with a ventilation system using a large black pillar of the present invention. In the present invention, the “large black pillar” is basically a pillar in the center of the wooden building or supporting the house as a central existence, and includes, for example, a through pillar. A through pillar is a pillar that passes through from the foundation to the bottom of the second-floor beam in a two-story or higher building. Examples of the material include reinforcing steel, wood, and the like, but when a new material is developed, the material is also included in the technical scope of the present invention according to its configuration and use.

  FIG. 1 is a diagram schematically showing a basic configuration of a house provided with a ventilation system using a large black pillar of the present invention from the side. 10 is a large black pillar, 20 is a hollow of the large black pillar, 30 is a rotating cylinder, 40 is a foundation layer, 50 is a foundation layer, and 70 is a roof.

The large black pillar 10 is configured to penetrate from the foundation layer 40 to the second floor beam. Each part of the large black pillar 10 is appropriately numbered, and includes a large black pillar under floor portion 11, a large black pillar first floor vicinity 12, a large black pillar second floor beam vicinity 13, and a large black pillar attic area 14.
The inside of the large black pillar 10 is a cavity 20 penetrating in the vertical direction from the foundation layer 40 to the bottom of the second floor beam, and a hollow attic cylinder 15 is arranged at the upper end of the large black pillar 10, and the large black pillar from the space of the base layer 50. 10 has a structure that creates a flow of air that blows through the cavity 20 in the roof 10 and the cavity in the attic cylinder 15 to the roof 71.
In the example of the first embodiment, the large black pillar 10 is configured by bundling a plurality of four pillars 10a, 10b, 10c, and 10d, and each pillar has one cavity penetrating in the vertical direction. Each cavity is a first cavity 20a, a second cavity 20b, a third cavity 20c, and a fourth cavity 20d.

Here, some of the cavities 20 have air passages blocked by the shielding walls 21 in the middle. In this example, the first cavity 20a is provided with a blocking wall 21a in the vicinity of the ceiling 12 on the first floor, and the conduction in the vertical direction is blocked in the vicinity 12 of the ceiling on the first floor. In the second cavity 20b, a blocking wall 21b is provided in the vicinity 13 of the ceiling on the second floor, and conduction in the vertical direction is blocked in the vicinity 13 of the ceiling on the second floor. The third cavity 20c and the fourth cavity 20d are not provided with shielding walls in the middle, and are electrically connected to the roof top 71 through the attic cylinder 15.
As will be described later, the reason why the shielding wall 21 is provided in the middle of the cavity 20 is to stop the flow of air in the vertical direction at the portion of the shielding wall 21 and change it to the side so as to guide it to the room or the ceiling of each floor. It is.

  On the side surface of the large pillar 10, a base vent hole (the base vent holes 111 to 118 in FIG. 2 to be described later) connecting the underfloor space of the base layer 50 and the cavity 20 of the large pillar 10 and air from the large black pillar cavity 20 into the house. A ventilation hole for guiding air (venting holes 121, 122, 131, and 132 in FIG. 2 to be described later) and a ventilation hole for guiding air from the house to the large black cavity 20 (venting holes 123, 124, 133, and 134 in FIG. 2 to be described later) 141, 142, 143, 144), which is a mechanism for ventilating and ventilating a house by a combination of large black pillar cavities, shielding walls, ventilation holes and ventilation holes.

The structure of the large black pillar, the shielding wall, the structure of the ventilation hole and the ventilation hole, and the state of the air flow are sequentially shown.
FIG. 2 is a schematic view of the cross section of the underfloor portion 11 of the large black pillar 10 as viewed from above. As shown in FIG. 2, the large black pillar 10 has a structure in which four single pillars 10 a to 10 d are bundled, and the bottom of the large black pillar 10 is firmly fixed to the base layer 40. The pillars 10a to 10d are provided with cavities 20a, 20b, 20c, and 20d. As will be described later, it is also preferable to provide a drainage mechanism 41 (FIG. 3) at the bottom of the large black pillar 10 in order to prevent water due to moisture or the like from accumulating on the bottom surface of the cavity 20.

  The underfloor portion of the large black pillar 10 is located in the foundation layer 50, and a foundation 51 is provided around it. A space between the bases 51 is an underfloor space 52. The underfloor space 52 often has a temperature lower than the outside air, and is, for example, about 20 to 25 degrees even in summer.

  As shown in FIG. 2, base vent holes 111 to 118 that connect the underfloor space 52 of the base layer 50 and the cavity 20 of the large black pillar 10 are provided on the side surface of the lower floor portion of the large black pillar 10. The shape of each foundation vent is not particularly limited. In the plan view of FIG. 2, the presence is represented as a dotted circle, but it is assumed that the hole is provided as a hole on the side of the large black pillar 10 as shown in FIG. 3. Further, the position and number of the base ventilation holes may be any positions where the ventilation described later is ensured. In this example, it is a circular hole, the base vent holes 111 and 112 in the cavity 20a, the base vent holes 113 and 114 in the cavity 20b, the base vent holes 115 and 116 in the cavity 20c, and the base vent hole 117 in the cavity 20d. And 118 are respectively provided. As shown by the arrows in FIG. 2, the cold air in the underfloor space 52 flows through these base vent holes 111 to 118, and the flow of air blown from the underfloor space 52 of the base layer to the roof top 71 as described later is a large black pillar. Made inside.

  FIG. 3 is a schematic view of the underfloor portion 11 of the large black pillar viewed from the side. It is shown that the cold air in the underfloor space 52 flows through the base vent holes 111 and 118 provided on the side of the large black pillar 10 and the flow of air flowing from the underfloor space 52 of the foundation layer into the large black pillar cavity is generated. .

Next, FIG. 4 is a schematic view of the vicinity of the first floor ceiling 12 of the large black pillar 10 as viewed from the upper surface direction. FIG. 5 is a schematic view of the vicinity of the first floor ceiling 12 of the large black pillar 10 as viewed from the side.
As shown in FIG. 4, in the first embodiment, the first cavity 20a is shielded in the middle by providing a shielding wall 21a. That is, the flow of air rising from the underfloor portion 11 into the first cavity 20a is blocked in the vicinity of the first floor near the ceiling 12 and is guided to the side with no place to go upward. For example, as shown in FIG. 5, a first-floor vent hole 121 is provided on the side of the large black pillar 10 below the shielding wall 21a, and the flow of air rising through the first hollow 20a of the large black pillar is caused by the shielding wall 21a. It is blocked and led to the indoors on the first floor through the duct 621 through the vent hole 121.

  As shown in FIG. 4, in the first embodiment, first-floor ventilation holes 123 and 124 are provided in the third cavity 20 c in the vicinity of the first-floor ceiling 12 near the first floor of the large black pillar. The first floor ventilation holes 123 and 124 connect the first floor space 61 and the third cavity 20c in the beam between the first floor ceiling and the second floor, and guide air from the first floor space 61 to the roof top 71. is there. Since the third cavity 20c is not provided with a shielding wall or the like, the flow of air rising from the lower floor portion 11 into the third cavity 20c continues to rise as it is. As shown in FIG. 5, the first floor ventilation hole 123 is provided in the vicinity of the first floor near the ceiling 12 in the middle, so that a force to suck up air is generated by the rising air flow generated in the third cavity 20c of the large pillar 10. Then, the air in the first floor indoor 61 is sucked up through the duct 623 (ventilated).

Next, FIG. 6 is a schematic view of the upper end surface of the large black pillar below the second-floor beam as viewed from the upper surface direction. 7A is a schematic view of the vicinity 13 of the lower black beam 10 of the large black pillar 10 as viewed from the side, and FIG. 7B is a schematic view of the vicinity 13 of the lower black beam 10 of the large black pillar 10 as viewed from the upper surface. .
As shown in FIG. 6, in the first embodiment, the second cavity 20b is shielded in the middle by providing a shielding wall 21b. That is, the flow of air rising from the underfloor portion 11 into the second cavity 20b is blocked under the second floor beam, and is guided to the side without having a place to go upward. For example, as shown in FIG. 7, a second-floor vent hole 131 is provided on the side of the large black pillar 10b below the shielding wall 21b, and the flow of air rising up the second hollow 20b of the large black pillar is obstructed by the shielding wall 21b. And led to the indoor 63 on the second floor through the duct 641 through the vent hole 131.

  FIG. 7 shows ducts 16 a, 16 b, 16 c, and 16 d that conduct between the large black pillar 10 supporting the second floor beam and the attic cylinder 15 connected to the large black pillar 10. The ducts 16a and 16b are positioned at the upper end of the large black pillar 10d and serve to guide the air in the cavity 20d further upward. The ducts 16c and 16d are located at the upper end of the large black pillar 10c and serve to guide the air in the cavity 20c further upward. For example, the air that has passed through the hollow 20 d of the large black pillar 10 d is guided to the attic cylinder 15 through the ducts 16 a and 16 b and escapes to the roof 71.

  Here, in the fourth cavity 20d, second-floor ventilation holes 133 and 134 are provided near the vicinity of the second-floor beam 13 near the large black pillar. The second floor ventilation holes 133 and 134 connect the second floor space 63 and the fourth cavity 20d in the beam between the second floor ceiling and the attic floor, and lead air from the second floor space 63 to the roof top 71. Since the second-floor ventilation holes 133 and 134 are provided in the vicinity of the second-floor beam vicinity 13 in this way, a force for sucking up air is generated by the rising airflow generated in the fourth cavity 20d of the large black pillar 10d, and the duct 643 is used. The air in the second floor indoor 63 is sucked up (ventilated). Since the third cavity 20c is not provided with a shielding wall or the like, the flow of air rising from the lower floor portion 11 into the third cavity 20c continues to rise as it is.

  The reason why the two ducts 16a and 16b are provided in the vicinity of the upper end of the cavity 20d instead of one duct and the two ducts 16c and 16d are provided in the vicinity of the upper end of the cavity 20c instead of one duct is that the upper end surface of the cavity The beam has a shape in which a part of the cavities 20c and 20d is blocked and the conductive space is rectangular, while the duct preferably has a circular cross section from the viewpoint of cost. This is because the air can be efficiently conducted upward by arranging the main lines. In this example, two ducts are provided.

Next, FIG. 8A is a schematic view of the attic vicinity 14 of the attic cylinder 15 viewed from the upper surface direction. FIG. 8B is a schematic view of the attic vicinity 14 of the attic cylinder 15 as viewed from the side.
As described above, in this configuration example, the third cavity 20c and the fourth cavity 20d out of the cavity 20 are not provided with a shielding wall or the like, and therefore the third cavity 20c and the fourth cavity 20d from the underfloor space 52. The flow of the air that has risen inside is guided from the ducts 16 a, 16 b, 16 c, and 16 d to the roof top 71 through the attic cylinder 15. The first floor ventilation holes 123 and 124 are provided on the side surface of the large black pillar 10c, and air in the first floor indoor 61 is sucked in through the duct 623, or the second floor ventilation holes 133 and 134 are formed on the side surface of the large black pillar 10d. Although the air in the second-floor indoor 63 is sucked in through the duct 643, the influence on the rising airflow from the underfloor space 52 to the rooftop 71 is small, and the third cavity 20c and the fourth cavity 20d In the interior of the attic 14, the rising airflow that passes through the attic cylinder 15 to the roof 71 is sufficiently strong.

  Here, as shown in FIG. 8, in the first embodiment, the attic ventilation holes 141 to 144 are provided in the attic cylinder 15. The attic ventilation holes 141 to 144 connect the attic space 66 to the third cavity 20 c and the fourth cavity 20 d in the vicinity of the attic, and guide air from the attic space 66 to the roof 71. Thus, the air in the attic space 66 is also ventilated. In this example, the attic ventilation holes 141 to 144 are configured such that a hole is directly formed in the wall surface of the attic cylinder 15 and a cylindrical body 17 is provided around the hole.

  The reason for providing the cylindrical body 17 is as follows. The attic space is relatively close to the roof, and if rainwater enters from the vicinity of the roof through the rotating cylinder 30 and the attic cylinder 15 to be described later, the attic space is directly inside the attic cylinder 15 from the attic ventilation holes 141 to 144. There is a risk of rainwater entering the cavity. If rainwater enters the cavity in the attic cylinder 15, it is transferred to the large black pillar 10, so it is not preferable that water enters the large black pillar which is the center of the house. Therefore, the cylindrical body 17 is provided around the attic ventilation holes 141 to 144 in order to prevent rainwater from entering.

Next, FIG. 9 is a diagram schematically showing an example of the structure of the rotating cylinder 30 provided at the tip of the large black pillar 10 on the roof 71. FIG. 9A is a diagram schematically showing a side view, and FIG. 9B is a diagram schematically showing a top view.
As shown in FIG. 9A, the casing of the rotating cylinder 30 is bent so that the lower end opening 30a faces downward and the upper end opening 30b faces horizontal. Further, the rotating cylinder 30 is provided above the large black pillar so as to be rotatable in the circumferential direction of the axis of the large black pillar 10 in the vicinity of the lower end thereof.

  The reason why the rotary cylinder 30 is rotatable is that the upper end 30b of the rotary cylinder 30 faces the leeward direction blowing on the roof 71. That is, it is for raising the updraft in the large black pillar 10 using the flow of the wind by rotating the entire rotating cylinder 30 so that the upper end opening 30b is located on the leeward side. When the upper end port 30b of the rotating cylinder is located on the leeward side, air near the upper end port 30b flows due to the wind flow, and the atmospheric pressure decreases. Since the lower end 30a of the rotating cylinder 30 is located near the upper end of the large black pillar 10, the pressure at the upper end of the large black pillar 10 is lowered, and the effect of improving the rising air flow generated in the large black pillar 10 is obtained.

  In the example of FIG. 9, the rotary cylinder 30 is provided with a wind face 31 so that the upper end port 30b of the rotary cylinder is easily oriented in the leeward direction. The rotary cylinder 30 is rotated by the wind face 31 in accordance with the direction of the wind, and the upper end 30b of the rotary cylinder is devised so as to face the leeward direction.

  FIG. 10 is a diagram schematically showing a mechanism for ventilating and ventilating a house and a state of air flow by combining a large black pillar cavity, a shielding wall, a vent hole and a vent hole described above. The air flow is indicated by arrows. As described above, the upward air flow generated from the underfloor space 11 into the large black pillar cavity 20 and the ventilation and ventilation of the first floor indoors using the upward air flow, the ventilation and ventilation of the second floor indoors, and the ventilation of the attic are performed. It is shown.

  The temperature shown in FIG. 10 is an actual measurement example of the natural temperature in summer when an air conditioner or the like is not used. The temperature is 24 degrees below the floor, 26 degrees near the floor of the first floor indoors, and the ceiling inside the first floor indoors. It was measured as 28 degrees near, 30 degrees near the floor inside the second floor, 33 degrees near the ceiling inside the first floor, and about 42 degrees in the attic space. This measurement result is only an example, the regional conditions where the house is built (such as another prefecture), the land conditions where the house is built (whether it is a mountain or seaside, north facing or south facing) Needless to say, it depends on various conditions, such as the type of external wall, depending on the land.

  As described above, an example of the structure of a house equipped with a ventilation system for ventilating and ventilating a house using a large black pillar by providing a base vent hole, a vent hole that conducts into the house and a ventilation hole on the side of the large black pillar is shown. However, it goes without saying that various design modifications and the like are possible within the scope of the technical idea of the present invention.

As Example 2, the device of each part shown in Example 1 is described.
First, a device for injecting rubber around the large black pillar in the foundation layer will be described.
FIG. 11 is a diagram schematically showing a state in which the base layer 40 and the large black pillars 10 of the base layer 40 are viewed from above. As shown in FIG. 11, in this configuration example, the large black pillar is fixed by injecting rubber 41 around the large black pillar 10. By surrounding the large black pillar 10 with the rubber 41, the base layer 40 and the large black pillar 10 can be firmly fixed and the large black pillar 10 can have a seismic isolation function due to the elasticity of the rubber. There are various types of seismic isolation structures, but it is effective to keep them small so as to buffer the magnitude of ground shaking caused by earthquakes. By wrapping a rubber member around the support member called the large black pillar, it is possible to buffer the magnitude of the rocking of the ground due to the earthquake, and the seismic isolation function can be obtained.
Since the cost for injecting rubber is not so large, there is an advantage that a realistic seismic isolation function can be provided at a low construction cost of a house.

Next, I will describe a device that consists of multiple pillars gathered together as a large black pillar.
In the first embodiment, a large black pillar that has been devised in the same way has been introduced, but will be described once again. Daikoku Pillar was the center of support in traditional Japanese houses, and thick, tall wood was used. In this invention, what has a cavity as a large black pillar is assumed, and although a material is not limited, an iron pillar is assumed, for example. The iron pillar has a high structural strength as a support member, but its weight is a problem. A crane is also used at the time of construction, but construction is not easy because thick steel pillars such as Daikoku pillars are too heavy. Therefore, consider gathering multiple thin pillars and using them as one large black pillar. In the configuration of the first embodiment, the large black pillars are gathered and bundled together, so that each one is a thin pillar having a thickness of about 1/4. Construction is relatively easy if the pillar is made of a steel pillar that is thinner than the thick black pillar. In the present invention, a plurality of cavities are provided as internal cavities. In Example 1, four cavities (first cavity 20a, second cavity 20b, third cavity 20c, and fourth cavity 20d are provided. ) Is provided. If the number of thin iron pillars corresponding to the number of cavities is used, the ease of construction and the preparation of the cavities can be achieved simultaneously.

Next, a technique for inserting a cushioning material (for example, a rubber plate) into the gap when a plurality of pillars are gathered together as the large black pillar 10 will be described. When it is assumed that the pillars will be slightly expanded and contracted due to changes in the temperature of the day, etc., when multiple single pillars are gathered together as the large black pillar 10, the single pillars will rub against each other unless any cushioning material is sandwiched between them. Sound may be generated by the presence or absence. In particular, if the single pillar is a metal material such as an iron pillar, the generated sound becomes a high metallic sound and may be annoying during sleep at night.
Therefore, it is preferable to add a device for sandwiching the buffer material 11 between the single columns as shown in FIG. For example, if the rubber plate 11 is sandwiched between the single pillars 10a to 10d, even if the single pillars a to d expand or contract due to temperature changes or the like, they will not rub against each other directly, and a temporary displacement of the rubber plate is also possible. It is absorbed by flexibility and elasticity and does not make sound. 12A is a diagram schematically showing a cross section of a single column, and FIG. 12B is a diagram schematically showing a rubber plate sandwiched between the inner surfaces of the single column 10 from the side. The rubber plate may be sandwiched between the entire inner surfaces of the single pillars 10 or may be sandwiched by appropriately dispersing small pieces.

  Next, a device for providing the air collecting body 53 that collects the air flow in the base vent holes 111 to 118 in the underfloor space 52 will be described. In the present invention, an air flow from the underfloor space 52 to the roof top 71 is generated, but the air flow in the underfloor space 52 is devised so that the air flow is easily concentrated on the base vent hole so that the air flow is easily generated. It is. FIG. 13 is a diagram showing an example in which a wind collecting body 53 is provided in the underfloor space 52 so that an air flow is easily generated. The air collecting body 53 has, for example, a large plastic funnel, one opening (inlet) is wide open, the other opening (exit) is narrowed, and the outlet is connected to the base vent holes 111 to 118. If air flows from the underfloor space 52 to the rooftop 71, the air is sucked up from the underfloor space 52 due to the sucking effect, so that the air in the underfloor space 52 is likely to gather in the base vent holes 111 to 118 by the air collecting body 53. become.

Next, a device for providing a small space that can be filled with an air improver on the wall surface adjacent to the large black pillar will be described. In the present invention, ascending airflow is generated in the hollow 20 of the large black pillar, and air spreads throughout the interior as shown in FIG. 11. Therefore, if the air improving agent is placed in the circulation path, the air in the entire interior is improved. It is valid.
FIG. 14 is a diagram schematically showing a longitudinal section of the large black pillar 10 and adjacent wall surfaces. As shown in FIG. 14, a cavity 20 is provided in the large black pillar 10, and a pocket-shaped small space 80 is provided on an adjacent wall surface. An air inflow hole 80a is provided near the lower part of the small space 80, an air discharge hole 80b is provided near the upper part, and a wind receiving plate 82 is provided. Guided to flow through. The small space 80 is filled with an air improver enclosure 81. The air improver enclosure 81 is not particularly limited as long as the air improver is encapsulated, and examples thereof include an air improver that is activated carbon and a net bag is used as the enclosure. By placing the air improving agent 81 on the air passage in this way, ventilation and ventilation in the house can be performed with the improved air.

Next, the device of the rotating cylinder 30 will be described.
The first device is a device for providing a water return 32. Since the rotary cylinder 30 is provided on the roof, it is exposed to rain and wind. Rain may be transferred obliquely and may enter from the upper end 30b of the rotating cylinder. Rain entering from the upper end 30b of the rotating cylinder is guided to the large black pillar 10, and when it enters the foundation layer through the large black pillar cavity 20, moisture accumulates in the house foundation and the house and disturbs the environment of the house.
Therefore, as shown in FIG. 15, it is effective to provide the water return 32 near the upper end 30b of the rotating cylinder. By providing the water return 32, there is an effect of preventing intrusion of rainwater. In addition, it is necessary to devise the height of the water return 32 suitably. As the height of the water return 32 is increased, the waterproofing effect is increased. However, when the height of the water return 32 is increased too much, the effect of increasing the ascending air current in the large black column cavity 20 is reduced. Therefore, the height of the water return 32 needs to be an appropriate height. Adjustments may be made in consideration of conditions such as the terrain where the house stands and whether or not the land is susceptible to rain.

The second device is a device in which a drain hole 33 is provided in front of the water return 32 (near the upper end of the rotating cylinder). When the water return 32 is used, it is possible to stop the intrusion of rainwater entering from the upper end port 30b of the rotating cylinder. However, if it is left as it is, water will accumulate in the vicinity of the water return 32, and there is a possibility that the water return 32 will be exceeded.
Therefore, as shown in FIG. 15, it is effective to provide a drain hole 33 in front of the water return 32 (near the upper end of the rotating cylinder). If the rainwater is allowed to escape from the rotary cylinder 30 through the drain hole 33, the rainwater will not accumulate.

  FIG. 16 is a view showing the water return 650 provided in the ducts 621 and 623 near the first floor attic 12 and the water return 650 provided in the ducts 641 and 643 near the second floor under the beam 13. FIG. 17 shows a configuration example of the water return 650 provided in the tubular body 17 surrounding the attic ventilation holes 141 to 144 provided in the attic space 66. The function of water return is the same as that of water return 32 in FIG.

The next idea is to provide an insect screen 34 at the upper end of the rotating cylinder 30 on the roof. Since the upper end opening 30b of the rotating cylinder is open on the roof, there is a possibility that insects and the like may enter. Since the upper end 30b of the rotating cylinder communicates with the inside of the house through the large black column cavity 20, when the insect enters, it will enter the inside of the house. For example, insects such as bees may nest, and small animals such as birds and bats may nest.
Therefore, as shown in FIG. 15, it is effective to provide a screen door-shaped insect net 34 at the upper end 30b of the rotating cylinder. By providing the insect screen 34, the effect of preventing the entry of these insects and small animals can be obtained.

  Next, a device for reducing the rotational friction by the force of the magnet at the connection point with the attic cylinder 15 will be described so that the rotary cylinder 30 can be easily rotated. The rotating cylinder 30 needs to be rotated by the wind so that the upper end port 30b of the rotating cylinder is directed to the leeward side. However, the rotating cylinder 30 is devised so that the rotating cylinder 30 can be rotated even if the wind force is weak. The rotating cylinder 30 is subjected to rotational friction at the connection point with the attic cylinder 15. Therefore, a magnet is used as an example of a device for reducing rotational friction. The rotating cylinder 30 has a band magnet attached to the inner peripheral side of the attic cylinder 15 and a band magnet attached to the outer peripheral side of the rotating cylinder 30 at the connection point with the attic cylinder 15. Here, if the band magnets are repelled so that the same poles face each other, a gap is generated between them. Thus, when there is a gap between the two, the rotational friction becomes extremely small. Thus, if the device for reducing the rotational friction is reduced, the rotating cylinder 30 easily rotates even with a weak wind, and the upper end 30b of the rotating cylinder faces the leeward side.

  As mentioned above, although preferred embodiment in the structural example of the house provided with the ventilation structure of this invention was illustrated and demonstrated, it is understood that various changes are possible without deviating from the technical scope of this invention. Will.
