  The present invention solves the above-mentioned problems of the prior art, and comprises a floor, a wall, and a roof made of a natural wood material and a layer of air therein, thereby forming a natural material and a natural material. By arranging the living space with a layer of air, it provides a cool living space by ventilation due to natural convection in the summer, and at the same time has a dehumidifying effect, heat insulating effect and soundproofing effect, and in the winter, it is solid wood Provided is a house provided with a ventilation structure having a relatively simple structure capable of securing a sufficient heat insulating function by a double or triple floor or wall formed of one or two air layers in a material. As an issue.

A first aspect of the present invention is a floor formed on a foundation on a foundation and having a layered underfloor ventilation passage therein,
Inside, a roof having a layered roof ventilation path communicating with the ventilation means configured in the large building, and a roof having an attic space communicating with the ventilation means immediately below the roof,

It is a house with a ventilation structure composed of

  According to a second aspect of the present invention, in the house having the ventilation structure according to the first aspect of the present invention, the main parts of the floor, the roof, and the outer wall structure are made of solid wood.

  According to the house having the ventilation structure of the present invention 1, the ventilation path in the roof and the attic space, the outer wall ventilation path connected to these via the upper ventilation port, and the lower wall ventilation path are connected thereto. The roof ventilation path and the underfloor ventilation path constitute a house ventilation path, and the ventilation path in the roof and the attic space are open to the atmosphere by the ventilation means configured in the large building of the roof. By releasing the heated air inside the heated walls and roof to the outside and keeping the inside air cool at all times, the heat from the outside can be shut off and the room can be kept cool. .

  In addition to the summer season, ventilation by natural convection as described above also ensures a moisture-proof effect, and furthermore, by separating indoors and outdoors with a thin air layer, it is possible to secure heat insulation and soundproofing effects. It will be. This can be implemented inexpensively with little need for dedicated space for house ventilation, since it can be easily incorporated into existing house structures.

  According to the house having the ventilation structure of the present invention 2, the main part of the floor, the roof, and the outer wall structure is made of a solid or wooden material having a much higher heat insulating property than concrete or earth wall, and is made of double or triple. With this configuration, the heat insulation can be further enhanced, and particularly, high temperatures in summer and cold in winter can be blocked, and the interior of the house can be maintained at a comfortable temperature.

  The house with the ventilation structure of the present invention is basically located on the foundation on the foundation and has a floor body with a layered underfloor ventilation passage inside, a roof ventilation passage and attic space communicating with ventilation means. And an outer wall structure having a two-layer outer wall ventilation path inside.

  The base extends on a foundation that supports the load of the entire house, and is formed of a base material that mediates between the foundation and the house structure thereon.

  It is important that the floor has a configuration in which a layered underfloor ventilation path is provided inside, and the floor is not particularly limited as long as the floor is configured as such. The floor body is, for example, a long joist extending at equal intervals in one direction directly above the base or via a large pull, and a rough floor stretched so as to cover the entire surface immediately above the joist. A long spacer member extending directly above the rough floor at the same position as the joist, and a floor plate stretched over the entire surface immediately above the spacer member, and the rough floor and the floor plate A configuration in which the enclosed space is used as a layered underfloor ventilation path can be adopted.

  By appropriately setting the thickness of the spacer member, the thickness of the layer of the underfloor ventilation path can be appropriately set. The thickness of the layer of the underfloor ventilation path is suitably about 18 mm. It is appropriate to use a solid wooden board for the floorboard and the rough floor. For example, a board such as cedar or oak may be used as the floorboard, and a cedar board or the like may be used for the rough floor. As a result, a double floor made of solid wood can be formed to enhance heat insulation.

  It is important that the roof has a configuration having a layered air passage inside the roof, and the configuration is not limited to a specific configuration as long as it is also configured as such. The roof includes, for example, an underlay plate stretched over the entire surface of the rafter, a long spacer member extending directly above the underlay plate at the same position as the rafter, and an entire surface immediately above the spacer member. A stretched field base plate, a roofing disposed thereon, a tiled bar disposed thereon at regular intervals in a direction perpendicular to the rafters, and a number of anchors fixed to the straw, and the underlay comprises It is possible to adopt a configuration in which a space surrounded by the board and the ground board is used as a layered air passage in the roof.

  The thickness of the air passage in the roof is appropriately about 18 mm, similarly to the thickness of the layer of the under-floor air passage. It is appropriate to use solid wooden boards for the underlaying board and the field board. For example, a plate material such as cedar or mizunara can be adopted as the underlay plate and the base plate. This makes it possible to form a double roof made of solid wood and improve heat insulation.

  Further, the roof needs to have the attic space immediately below the roof, and this space is provided between the roof of the house and the ceiling suspended from a beam or a girder laid horizontally on top of the pillar. The structure has a plurality of shed bundles for supporting the load of the roof and structures such as double beams inside.

  And, as described above, it is extremely important that the above-described ventilation path in the roof and the attic space communicate with the ventilation means configured in the large building, but the configuration of the ventilation means is not limited to a specific one. . For example, the ventilation means includes a pedestal arranged on both sides of the large building, and a ventilation means main body fixed on the large building by mounting and fixing the pedestals on both sides with U-shaped joints having a U-shaped cross section on both sides. An opening formed alternately on the inner and outer rising portions of the U-shaped coupling portion, and a cover member covering the ventilation means main body, both sides of which are extended to the outside of the U-shaped coupling portion. A cover member that is bent downward, and a lower processing plate member that is extended upward from an outer edge of the cover member to an outer side of each of the cover members from below the both U-shaped coupling portions, The ventilation path in the roof and the attic space may be configured to communicate with the central lower part of the ventilation means main body immediately below the large building.

  By such ventilation means, the hot air that has risen up to the ventilation path in the roof and the attic space naturally rises to the large building and is efficiently ventilated, improving indoor cooling and removing moisture. However, the occurrence of dew condensation can be avoided.

  The outer wall structure is, of course, a structure that supports the roof at the periphery thereof, further has a two-layer outer wall air passage therein, and communicates with the attic space above the outer wall air passage inside. A layered underfloor vent formed on the floor below the inner outer wall airway, and an upper airway communicating with the in-roof airway above the outer outer wall airway. It has a lower vent that communicates with the road, and the inner and outer outer vents need to communicate with each other at any location, and if this is satisfied, adopt a free configuration. Is possible.

  The outer wall structure includes, for example, a space between two adjacent pillars erected on the base with an inner wall material and an outer wall material, and the base and the adjacent two A partition plate for partitioning the entire space surrounded by a horizontal member such as a pillar and a beam or a girder above the pillar can be provided, and the spaces on both sides thereof can be formed in the outer wall ventilation passages. If necessary, using an outer or inner space, a diagonally positioned brace is provided between the two columns from the top of one column to the bottom of the other column, Alternatively, a brace positioned in an X shape from both sides can be arranged to easily secure the necessary wall strength. A slight gap is left between these braces and the partition plate, or between the inner wall material and the outer wall material, and the outer wall ventilation path is configured to reliably continue to the upper and lower ends.

  The upper ventilation port of the inner outer wall ventilation path is configured to open to a portion above the inner wall material and located above the ceiling, and communicates with the attic space. It is preferable that a plurality of openings constituting the upper vent be formed by arranging a plurality of openings in the lateral direction at appropriate intervals. Further, the upper vent of the outer outer wall ventilation path is formed by partially cutting out a portion of the eaves girder material which is in contact with the outer wall material, and opening a corresponding portion of the lower lining plate, and communicating with the roof ventilation path. be able to. These are also preferably arranged at appropriate intervals. The lower vent may be configured by opening a portion below the inner wall material and located between the floor plate and the rough floor. Since the underfloor ventilation path is independent between each adjacent spacer member, the lower ventilation hole needs to be opened at a portion facing each lower part of the inner wall material.

  As described above, the two-layer outer wall air passages need to communicate with each other, and the communication is performed by forming an opening in a partition plate that separates the inner and outer outer wall air passages at an appropriate position. It can be realized by.

  Therefore, according to the house provided with the ventilation structure of the present invention, in the summer, high-humidity hot air trapped in the underfloor ventilation path, the inner and outer outer wall ventilation paths, the roof ventilation path and the attic space by natural convection, It can be easily and reliably discharged from the ventilation means configured in the large building. Therefore, the ventilation layer formed by the underfloor ventilation path, the inner and outer outer wall ventilation paths, the in-roof ventilation path, and the attic space is filled with relatively low-temperature (cool) air. , And can be kept relatively cool.

  In winter, air movement due to convection inside the underfloor ventilation passage, both outer wall ventilation passages, roof ventilation passages, and attic space is reduced, while the heat insulation effect of the solid wood material that composes these components is not sufficient. It can function and reduce the conduction of outside cold air into the room.

  Further, regardless of the season, the dehumidifying effect can be ensured by ventilation, and the soundproofing effect can be also ensured by dividing the indoor and outdoor areas into thin air layers. In addition, the present invention can be easily incorporated into an existing house structure, and can be realized inexpensively with almost no special space required.

  For example, in the hot and humid summer season, the high-humidity air that is trapped in the underfloor ventilation paths 6, 6,... Is discharged by natural convection and cool air is guided into the inside, so that the inside of the house 1 wrapped in these can be isolated from hot air in summer and maintained in a comfortable state.

  In the spring or autumn, the air inside the underfloor ventilation passages 6, 6,..., The outer wall ventilation passages 4, 4, the roof ventilation passage 8, and the attic space 9 may vary depending on the climatic conditions such as the temperature and humidity at that time. By being appropriately released by natural convection or maintaining a stagnant state, the temperature and humidity inside them are moderately maintained, and the inside of the house 1 surrounded by these is maintained at a comfortable temperature and humidity state. Become

  Further, in winter, the movement of air in the underfloor ventilation passages 6, 6,..., The outer wall ventilation passages 4, 4, the roof ventilation passage 8, and the attic space 9 is in a stagnant state. The transmission of cold air indoors is reduced.

  In addition, irrespective of the season, the ventilation inside the underfloor ventilation passages 6, 6,..., The outer wall ventilation passages 4, 4, the roof ventilation passage 8, and the attic space 9 are ventilated through the ventilation unit 12, thereby ensuring the moisture-proof effect. Furthermore, the soundproofing effect can be ensured by partitioning the indoor and outdoor areas with a thin air layer defined by the outer wall ventilation paths 4, 4 and the like. Further, for the sake of constituting the underfloor ventilation passages 6, 6,..., The outer wall ventilation passages 4, 4 and the roof ventilation passage 8, those portions are double or triple separated by a cedar board or the like which is a solid wood material. Therefore, the heat insulation and the sound insulation are further improved.

  In addition, the house provided with the ventilation structure of this embodiment can be realized at a low cost with little need for a dedicated space because it can be easily incorporated into an existing house structure.
