Description

Technical Field

[0001] The present invention relates to an interior corridor daylighting structure, which can introduce natural light into the internal shared corridors of apartment houses such as condominiums and the internal corridors of office buildings, etc., and relates to an interior corridor daylighting structure that is also excellent in the exterior design of the building.

Background Art

[0002] Conventionally, in high-grade condominiums and the like, internal shared corridors (hereinafter referred to as interior corridors) are often adopted because quietness and a sense of calm can be obtained. Generally, since external light does not enter the interior corridor, downlights or the like are arranged along the interior corridor to ensure a predetermined brightness. On the other hand, since the entire interior corridor cannot be illuminated only by lighting such as downlights, there may be a feeling of stuffiness, and there is also a desire to introduce natural light while maintaining the sense of calm in the interior corridor. If a daylighting structure such as a window is provided on the outer wall surface side in response to this desire, there is also a problem that the inside of the building can be seen through from neighboring buildings and privacy cannot be ensured.

[0003] In connection with this problem, in order to provide daylighting for the rooms on the outer corridor side of apartment houses such as condominiums, a condominium structure has been proposed in which a bay window for ensuring the privacy of the rooms is provided from the room side to the outer corridor side (Patent Document 1).

[0004] The condominium structure disclosed in Patent Document 1 is such that a bay window assembly projects from the room side to the outer corridor. This bay window assembly consists of a triangular bay window-shaped portion and a surface grid, and a frosted glass or glass block having translucency is used for the hypotenuse portion of the projecting triangle, so that natural light from the outer corridor side can be taken in while ensuring the privacy of the room interior.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In Patent Document 1, natural light from the outer corridor can be introduced into the living room by the disclosed bay window assembly, and privacy in the living room can be ensured at that time, but it does not consider the introduction of natural light into the inner corridor itself. Therefore, it is desirable to install a lighting structure similar to the bay window assembly on the outer wall surface of the building. In that case, since the bay window assembly disclosed in Patent Document 1 is a structure applied to the window portion of each individual living room, when arranged on the building exterior, there is a risk of lacking the integrity and aesthetic appearance of the building outer wall surface.

[0007] Therefore, an object of the present invention is to solve the problems of the above-described conventional technologies, and to provide an inner corridor lighting structure having a superior appearance design that enables the introduction of natural light into the inner corridor while ensuring privacy inside the building.

Means for Solving the Problems

[0008] In the present invention, a widened floor is formed by projecting a part of the inner corridor toward the outer wall side of the building at a predetermined interval in the longitudinal direction of the building, and a corner column portion extending in the building height direction is integrally constructed with the building on a part of the building outer wall following the shape of the widened floor, and a lighting window corresponding to each floor of the building is provided on one surface of the corner column portion. Width It is characterized in that.

[0009] The widened floor is preferably triangular, and the corner column portion is preferably substantially triangular prism-shaped.

[0010] The triangular shape is preferably a right isosceles triangle, and its two hypotenuses preferably correspond to two surfaces of the corner column portion.

[0011] The lighting window preferably has an overall height substantially equal to the height from the floor surface to the ceiling surface of the inner corridor.

Effects of the Invention

[0012] As described above, according to the present invention, it is possible to ensure privacy inside buildings such as apartment houses, allow natural light to enter the inner corridor, and realize a daylighting structure having an excellent design appearance.

Embodiments for Carrying Out the Invention

[0014] Hereinafter, embodiments of the inner corridor daylighting structure of the present invention will be described with reference to the accompanying drawings.

[0015] Figs. 1 and 2 are a plan view (roof plan), a front view (entrance side elevation view), and a rear view (outer staircase side elevation view) showing the overall shape of a three-story apartment building 1 adopting an embodiment of the inner corridor daylighting structure of the present invention. In Fig. 1, a part of the roof 2 is cut away, and a part of the inner corridor 3 and the living room 4 are drawn. As shown in this figure and Fig. 2(a), this apartment building is composed of a configuration in which a plurality of one-room type living rooms 4 of substantially the same shape are arranged facing the inner corridor 3 extending in the longitudinal direction of the building 1. And as shown in Figs. 1 and 2(b), on the building outer wall surface 5 on the rear side (outer staircase side) of the building 1, an elongated substantially triangular prism-shaped daylighting structure 10 is integrally constructed with the outer wall surface 5. As shown in each figure, this daylighting structure 10 is constructed at five locations at predetermined intervals along the longitudinal direction of the building outer wall surface 5 excluding the living rooms 4A where a part of both ends of the building 1 projects to the rear side, two outer staircases 6, and the elevator installation section 7.

[0016] The daylighting structure 10 of the present invention is composed of a part integrally constructed with the building outer wall surface 5, the external shape of which is, as shown in Fig. 2(b) and Fig. 3, a triangular prism shape that extends over substantially the entire height of the building 1 with a substantially right-angled isosceles triangle shape in plan view, and the surface is finished in the same manner as the other outer wall surface 5. The top 10c of the triangular prism shape is, as shown in Fig. 3, a flat triangular pyramid-shaped roof shape.

[0017] In this embodiment, among the two wall surfaces 10a and 10b corresponding to the hypotenuse of a right-angled isosceles triangle, a daylighting window 20 for introducing natural light into the inner corridor 3 on each floor is provided at substantially equal intervals in the building height direction on one of the wall surfaces 10a. In this embodiment, as shown in FIG. 3, each daylighting window 20 is composed of a two-stage window (hereinafter, also denoted by the same reference numeral 20). The upper window 20U is a single-hung window, and the lower window 20L is a FIX window. Transparent glass is used for all window glasses. Also, as shown in FIG. 5 to be described later, the height of the two-stage window 20 is substantially equivalent to the height of the inner corridor 3, and sufficient daylighting is achieved over a wide range from the floor surface to near the ceiling of the inner corridor 3. In this embodiment, the side width is 800 mm in terms of the wall core dimension, and a daylighting window 20 with a well-balanced width (for example, about 450 mm) is incorporated with respect to this width. Needless to say, various window dimensions, window division numbers, window frame types, window opening and closing structures, and window glass types can be adopted as long as they are suitable for the building exterior.

[0018] Further, as shown in FIG. 3, the daylighting structure 10 of this embodiment has daylighting windows 20 provided on each floor of the three-story building 1. However, on floors where daylighting is not required, the window itself may not be provided and the wall surface may be left as it is, or on the top floor or the ground floor, it is also possible not to provide the daylighting structure 10 itself. On the other hand, it is also possible to provide small daylighting windows 20 on both wall surfaces 10a and 10b of the daylighting structure 10.

[0019] FIG. 4 is a partial plan view showing a cross-sectional shape of a daylighting structure 10 integrally formed with a part inside the building and an outer wall surface 5 of the building, and shows substantially the same location as the part shown by cutting out a part of the roof 2 in FIG. 1. In the figure, two daylighting structures 10 are located with an external staircase 6 in between. In these daylighting structures 10, two-story windows 20 are provided on the surfaces facing the central side of the building (the right side in the figure). A single-opening window that can be opened and closed as shown is adopted for the upper window 20U of the two-story window 20 for ventilation of the inner corridor 3. Since the glass surfaces of each daylighting window 20 form an angle of about 45° with an adjacent building (not shown), it is difficult to see through the inside of the inner corridor 3 from the side of the adjacent building due to reflection of the glass surface and the like. Thus, the privacy inside the building is sufficiently ensured. Also, the light from the daylighting window 20 shines obliquely into the inner corridor 3 and illuminates the inner corridor 3 brightly over a wide range, so the sense of enclosure of the inner corridor 3 is alleviated. Furthermore, the wall surface position of the inner corridor 3 where the daylighting structure 10 is provided follows the shape of the projecting widened floor 3a, forms a substantially right-angled isosceles triangular prism shape, and natural light is taken in from the daylighting window 20 into the widened space 12 (FIG. 5) formed above the widened floor 3a, contributing to further elimination of the sense of enclosure of the inner corridor 3.

[0020] FIG. 5 is a partial developed view showing a part of the wall surface of the inner corridor 3 along the arrow line shown in FIG. 4. As shown in the figure, the widened space 12 of the inner corridor 3 of the daylighting structure 10 reaches the full height from the floor surface to the ceiling of the widened floor 3a projecting in a triangular shape, and the two-story window 20 is provided over substantially the full height of the widened space 12. Therefore, sufficient natural light can be taken into the inner corridor 3.

[0021] Figs. 6(a) to 6(d) show various morphological examples of the planar form of the daylighting structure 10 of the present invention. Fig. 6(a) shows the planar form of the daylighting structure 10 shown in Figs. 1 and 4. In this daylighting structure 10, the hypotenuse of the triangular shape forms an angle of approximately 45° from the inner corridor 3 side, and the space formed above the widened floor 3a that projects in a substantially right-angled isosceles triangle shape is the widened space 12 of the inner corridor 3. On the other hand, in the daylighting structure 10 shown in Fig. 6(b), an extended space 12 that projects in a triangular shape is also formed. In this extended space 12, one side that becomes the wall surface 10b forms an angle of approximately 30° with the straight inner corridor 3, and the other hypotenuse where the daylighting window 20 is installed forms an angle of approximately 60° with the inner corridor 3. By making the extended space 12 such a right-angled triangle shape, natural light from the daylighting window 20 can penetrate deeper into the inner corridor 3, and the sense of enclosure of the inner corridor 3 is further eliminated. Also, since the angle at which the wall surface of the daylighting structure 10 bends and protrudes from the building outer wall becomes gentler, it is possible to expect the effect that the daylighting structure 10 provided on the building outer wall surface 5 becomes less conspicuous. Fig. 6(c) shows an example in which the daylighting window 20 provided in the daylighting structure 10 is enlarged when privacy protection from adjacent buildings is not so much required. In this case, by suppressing the angle formed by the hypotenuse on the daylighting window 20 side, it is possible to sufficiently introduce natural light into the inner corridor 3 while suppressing the influence on the building appearance. In the daylighting structure 10 shown in Fig. 6(d), the extended space 12 is about 1 / 2 of the example shown in Fig. 6(a), but the wall surface 10b without the daylighting window 20 protrudes slightly orthogonally from the building outer wall surface 5 and is not conspicuous in the building appearance, so it can be applied to cases where it is desired to provide many installation locations in consideration of the design balance of the building outer wall surface 5 in other locations.

[0022] In the above description, an example in which the daylighting structure 10 is provided in an apartment building provided with an inner corridor has been described, but it goes without saying that it can also be adopted in office buildings, hotels, etc. having the same type of internal corridor.

[0023] Note that the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in each claim. That is, embodiments obtained by combining technical means appropriately modified within the scope shown in the claims are also included in the technical scope of the present invention.
