Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building having an intermediate floor between an upper floor and a lower floor in a main body of a building, the intermediate floor being lower than the floor height of the upper floor and the lower floor. The present invention relates to a technology that enables a portion of the height of the middle floor of a two-story or more house to be effectively used for the exterior including windows, daylighting, or for housing design.

[0002]

BACKGROUND ART For example, a building such as a general house or an apartment house is provided with a closet, a roof bag, a storage door, etc. for storing articles, and in recent years, an underfloor storage space utilizing an underfloor space, and further an attic. Storage is provided.

[0003] In recent years, along with changes in the family structure and life pattern, furniture and many other articles have been prepared in dwelling units, and the use forms of the articles have become more frequent according to the seasons and the like. For this reason, a large storage space for storing these articles in a building as necessary has been required. In this regard, from the viewpoint of effective use of the site due to the soaring land and effective use of the volume in the building, it is desired to provide a storage space as large and efficient as possible in the building.

As a building taking such points into consideration, for example, a storage space is formed over almost the entire space between the ceiling of the lower-floor room and the floor of the upper-floor room, and the storage space is further provided on the floor of the upper-floor room. A so-called large-scale detached house with a storage layer has been proposed, which is provided with an opening / closing lid for loading and unloading articles. However, in a house with such a structure, a large storage space can be provided in the building, but since the storage space is simply wide, the so-called large underfloor storage is formed. However, there is a problem in that it is not easy to use when putting in or taking out articles. In addition, the height of each room, such as a living room, is not different from the normal height by simply providing a large storage space over almost the entire space between the upper and lower floors. Since the height of the entire building is increased, the internal volume of the building is unnecessarily increased, which causes a problem that the planar internal volume of the internal volume of the building cannot be effectively used.

[0005]

Therefore, the present applicant has
We have developed a building with an intermediate floor (staircase floor) with a staircase between the upper floor and the lower floor in the main body of the building, and have already proposed this (Japanese Patent Application No. 5-324589). Due to various restrictions, the middle floor of this building is lower than the floor heights of its upper and lower floors. However, for example, since it has a floor height of around 1.2 to 1.4 m and is equipped with stairs that connect to the upper and lower floors, it is possible to store part of the middle floor as a large storage room like a warehouse. The room is designed so that it can be used more easily. In addition, the parts other than the storage room on the intermediate floor are used to raise the ceiling of the room on the lower floor so that the intermediate floor can be effectively used three-dimensionally.

As a result of further studies on the effective use of the middle floor of the building, the present inventors have found that the following problems occur. For example, in a two-story house having an intermediate floor, the height of the entire building is higher than that of a normal two-story house by the height of the intermediate floor. Therefore, it may be necessary to provide a window on the outer wall of the middle floor for improving the appearance or for lighting. Further, when the ceiling of the living room, for example, on the lower floor, is raised by the ceiling of the middle floor, it is necessary to take sufficient consideration for the lighting of the living room accordingly. On the other hand, it is desirable that the window provided on the outer wall of the middle floor is located at the most preferable position in terms of appearance or lighting, while the window provided in the living room on the first floor is the interior of the living room. In some cases, it may be desirable to provide it at the most preferable position from the viewpoint of the above or the lighting. In other words, the position of the window desired from the point of view of the building or from the viewpoint of daylighting and the position of the window desired from the inside of the building often differ from each other. Therefore, the arrangement, size, shape, or structure of the windows Therefore, there is a problem that the degree of freedom in design is reduced.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above points, and not only the middle floor can be used as a large-sized storage room which is easy to use, but also the window provided on the outer wall of the middle floor. Can be installed at the most preferable position on the exterior or on the lower floor, for lighting, etc., and for the window on the lower floor, it can be installed at the most preferable position for interior or lighting. It is possible to provide a technology that enables efficient and effective use of the height of the middle floor for house design that takes into account the exterior including windows, daylighting, and the interior. Is.

The partition wall for partitioning the internal space and the outer wall of the middle floor are provided so as to face each other with a space therebetween. Therefore, by providing a lighting device in the space between the outer wall and the partition wall of the middle floor, it can be used for indirect illumination or direct illumination of the internal space. In that case, a living room, a living room such as a Japanese-style room, or an entrance hall is particularly suitable as the internal space for lighting.

In order to improve the appearance of the building by windows or unify the appearance of windows, in addition to the windows of the outer wall portion facing the partition wall on the middle floor, other outer wall portions located around the middle floor are provided. It is also preferable to provide a plurality of windows with the same configuration. In that case, the window of the other outer wall portion of the intermediate floor can be used as the window of the storage room provided in a part of the intermediate floor.

Further, in the present invention, in consideration of the effect of daylighting to the inner space of the lower floor, windows which are opposed to each other are provided on the outer wall of the middle floor and the partition wall, and the inner space is opened through the windows. The method of daylighting is actively adopted.
At that time, by changing at least one of the positional relationship, the size, and the shape of the window on the outer wall of the middle floor and the window on the partition wall, the light collected through each of the windows is changed to the natural light to the internal space. The method of using as direct lighting or indirect lighting of is adopted. In the case of indirect illumination of natural light, it is also preferable to apply light collected through each window to the ceiling of the internal space to be used as indirect illumination of the internal space. This is because no special device is required for the indirect lighting.
