Definitions

  • the present invention relates to a building.
  • vacuum insulation panels are often used on outer walls of a building to keep the interiors of the building comfortable.
  • air conditioning panels have also been suggested, in which the panels themselves provide the air conditioning function, such as heat pipe panels that allow heat transmission from one surface to the other surface while blocking the heat transmission from the other surface to the one surface, and refrigerator panels in which an absorption or adsorption refrigerator is formed into a panel shape (for example, see Patent Literatures 1 and 2).
  • each floor blocks upward and downward streams, making it difficult to spread comfortable air throughout the building. Therefore, an atrium may be provided so as to ensure upward and downward streams, but this can greatly reduce the floor area on the upper floors, which is not preferable.
  • the present invention has been made to solve the problems described above, and accordingly, an object is to provide a building that can ensure upward and downward streams without greatly reducing the floor area of the upper floors.
  • a building according to the present invention includes:
  • the floor part is not limited to the one that actually functions as a floor on which people walk or sleep, but refers to a lower structure in the floor.
  • the building capable of ensuring upward and downward streams without reducing the floor area of an upper floor significantly can be provided.
  • FIG. 1 is a perspective view of an example of a building according to an embodiment of the present invention.

  • the outer wall OW is directly or indirectly attached to a pillar (see symbol P in FIGS. 3 and 4 ), and one side faces the exterior space.
  • the outer wall OW employs so-called air-conditioning panels AP.
  • the air-conditioning panel AP provides an air-conditioning effect on the indoor side that is the other side, and includes a heat pipe panel or a refrigerator panel, for example.
  • the heat pipe panel is a panel that allows heat transmission from one surface side to the other surface side and prevents the heat transmission from the other surface side to the one surface side.
  • This heat pipe panel is a panel that has a working fluid therein and allows heat transmission from one surface side to the other surface side as the working fluid evaporates on one surface side and takes heat, and the vapor generated by the evaporation reaches the other surface side and dissipates the heat of condensation from the other surface side.
  • This heat pipe panel has an inclined structure therein and has a structure in which the working fluid condensed on the other surface side returns to the one surface side by its own weight.
  • the heat pipe panel has a heat insulation layer having a vacuum or the like therein, prevents heat transmission from the other surface side to the one surface side, and has high heat insulation performance.
  • the refrigerator panel is a panel that provides a refrigerating function by absorption or adsorption, and includes, in a plate shape, a regenerator, a condenser, an evaporator, and an absorber which form an absorption refrigeration cycle, or an adsorber, a condenser, and an evaporator which form an adsorption refrigeration cycle.
  • the refrigerator panel also includes a vacuum insulation part (heat insulation layer) and the like, and has high insulation performance.
  • the opposite surface side of the outer wall OW that is, the indoor side is not formed with the interior decoration such as gypsum board or plywood and directly exposed to the indoor air.
  • the air-conditioning panel AP is adopted in all of the outer wall OW except for the triangular or trapezoidal upper portion U, embodiments are not limited thereto, and the air-conditioning panel AP may be adopted only in a part of the outer wall OW except for the upper U.
  • the air-conditioning panel AP is not limited to the heat pipe panel and the refrigerator panel, but may be any other type of panel as long as it provides an air-conditioning effect on the indoor side, such as a panel that is simply supplied with electric power and provides a cooling effect with electric power.
  • FIG. 2 is a perspective view of the structure when the wall part 10 is removed from the building 1 according to the present embodiment.
  • the building 1 according to the present embodiment includes four floors, that is, a first floor H1 and a second floor H2 serving as living room spaces, an underfloor floor UF, and an attic BH.
  • the first floor H1 is a so-called first floor.
  • the underfloor floor UF is provided below a floor part F1 of the first floor H1.
  • the underfloor floor UF is a floor of which a bottom surface is the foundation of the building 1.

  • the floor part F2 of the second floor H2 has a gap S with respect to the outer wall OW, in which the gap S is within a thickness range of the pillar P (less than the pillar width). Therefore, in the building 1 according to the present embodiment, air can be circulated through the gap S between directly higher floor (that is, the second floor H2) and directly lower floor (that is, the first floor H1) of the floor part F2.
  • a beam width W1 of a girth part BD is made narrower than a pillar width W2, and the narrowed portion defines the gap S from the outer wall OW.

  • the gap S is not limited to being formed by narrowing the beam width W1 of the girth part BD.
  • the building 1 (see FIG. 1 ) has a furring strip BE attached to the outside of the pillar P, as shown in FIG. 4(a) .
  • the outer wall OW is attached to the furring strip BE, and is attached to the pillar P via the furring strip BE. Therefore, the gap S corresponding to the thickness of the furring strip BE is formed between the furring strip BE and the outer wall OW.

  • the building 1 according to the present embodiment can generate upward and downward streams in the atrium AT by rotating the ceiling fan SF in the atrium AT. Furthermore, in conjunction with the generation of upward and downward streams in the atrium AT, it is also possible to generate upward and downward streams using the gap S, thereby achieving smooth air circulation in the building 1.
  • the atrium AT shown in FIG. 5 vertically extends through the ceiling part C (see FIG. 2 ) of the second floor H2 and up to the attic BH (see FIG. 2 ). That is, the atrium AT shown in FIG. 5 vertically extends through three floors.
  • a first direction faces the outer wall OW (see FIG. 1 , and the like) on the second floor H2, and a handrail HR is provided in a second direction opposite to the first direction.
  • the atrium AT is provided with spandrel walls SW in a third direction and a fourth direction that intersect the first direction and the second direction at right angles.

  • the first to third roll screens RS1 to RS3 are each stretched to the vicinity of the ceiling part C (see FIG. 2 ) of the second floor H2, thereby separating the space portion SP from the space in the second floor H2.
  • the atrium AT directly connects the first floor H1 and the attic BH.
  • the upward and downward streams pass through without blowing into the second floor H2.
  • first to third roll screens RS1 to RS3 are not limited to being extended to the ceiling part C of the second floor H2, and can be stopped halfway. Therefore, the space portion SP can be partially closed and the remaining part can be left open, and the upward and downward streams distribution and the air collection height on the second floor H2 can be arbitrarily determined.
  • the building 1 shown in FIG. 1 has the gap S from the outer wall OW. Accordingly, the air of the outer wall OW that is air-conditioned by the air-conditioning panel AP moves through the gaps S in a plurality of floors as upward and downward streams.
  • the ceiling fan SF can generate the upward and downward stream in the atrium AT, thereby generating upward and downward stream through the gap S. For example, if a downward flow is generated in the atrium AT, an upward flow in the opposite direction can be generated in the gap S accordingly.
  • the building 1 includes four floors, and the gap S is also provided in the floor part C of the attic BH and the floor part F1 of the first floor H1.
  • the attic BH and the underfloor floor UF are generally available, and the attic BH and the underfloor floor UF have no or few inner walls and are not equipped with furniture, and the like, and can thus suitably allow generation of a horizontal flow.
  • the attic BH and the underfloor floor UF it is necessary to generate not only upward and downward flows but also the horizontal flow. Therefore, by using the attic BH and the underfloor floor UF, it is possible to preferably perform air circulation.
  • At least one of the floor parts F1, F2, and C of the upper floors H1, H2, and BH has the gap S with respect to the outer wall OW, which is within the thickness range of the pillar P, and the gap S enables air circulation between the directly lower floor and directly higher floor among the floor parts F1, F2, and C. Therefore, according to the building 1, it is possible to ensure the upward and downward streams through the gap S without providing the atrium AT having a size equal to or greater than a predetermined size. Therefore, it is possible to ensure the upward and downward streams without significantly reducing the floor area of the upper floors.
  • the building 1 has the girth part BD with the beam width W1 narrower than that of the pillar P, and the gap S is formed between the girth part BD and the outer wall OW. Therefore, it is not necessary to add a new structure to provide the gap S, and by adjusting the beam width W1 of the girth part BD, it is possible to ensure the upward and downward streams without significantly reducing the floor area of the upper floor.
  • the gap S is formed by attaching the outer wall OW to the pillar P via the furring strip BE, the gap S can be formed by using the furring strip BE without working on the pillar P, the girth part BD, and the like, and the strength or the like of the building 1 can be hardly affected and the upward and downward streams can be ensured.
  • the air-conditioning panel AP has a heat insulation layer that insulates the interior of the room from the exterior space, and has no interior material on the indoor side of the gap S, so that the indoor surface facing the interior space is directly exposed to the interior air. Accordingly, the room air can be directly air-conditioned on the indoor surface, and the room air can be preferably circulated through the gap S.
  • the building 1 has the ceiling fan SF and the atrium AT vertically extends through the floors including the floor provided with the gap S, the atrium AT can be used to generate upward and downward streams, and it is thus possible to facilitate the upward and downward streams using the gap S. Therefore, it is possible to contribute to smooth air circulation.
  • the atrium AT may be considered as a component that reduces the floor area of the upper floors, but since the structure corresponding to the atrium AT can be skipped by the amount of the gap S, the floor area of the upper floors is not greatly reduced.
  • the building 1 includes the roll screen RS on the second floor H2 of the atrium AT for closing the space portion SP facing the atrium AT and the second floor H2. Accordingly, when shielded by the roll screen RS, the upward and downward streams can be generated in such a form that the streams pass through the second floor H2, and when not shielded by the roll screen RS, upward and downward streams can be generated without passing through the second floor H2. Therefore, it is possible to select a floor for the upward and downward stream air circulation.
  • the directly higher floor of the gap S is the attic BH, and since the attic BH where no walls or furniture are normally installed can be used, this can contribute to suitably generating the horizontal flow that is as essential as the upward and downward streams.
  • the directly lower floor of the gap S is the underfloor floor UF, and since the underfloor floor UF is usually not provided with inner walls, furniture, and the like, it is possible to contribute to suitably generating a horizontal flow in addition to the upward and downward streams. Further, even when the underfloor floor UF is blocked by the foundation, providing an opening in a part of the foundation can contribute to the favorable generation of horizontal flow.
  • the atrium AT faces the outer wall OW in the first direction, but embodiments are not limited thereto, and may not face the outer wall OW in any of the first to fourth directions.
  • the gap S may be within the thickness range of the thickest pillar P.
  • the pillar P extends from the directly lower floor H1 to the upper floor H2 through the floor part F2, but the pillar P only needs to be provided on the floor part, and does not necessarily have to pass through from the directly lower floor H1 to the upper floor H2.
  • the means for shielding the space portion SP is not limited to the roll screen RS, and may be another object such as a slidable wall.
  • the means for generating a pressure difference is not limited to the propeller type like the ceiling fan SF, and for example, other types of fans such as a sirocco fan and a turbo fan may be used, and also not limited to the fan as long as it can generate a pressure difference.
  • the atrium AT may utilize a space in which stairs are provided.
