Description

  The present invention relates to a daylighting structure of a building mainly applied to a house.

  Incorporating natural light into a building is very important from the viewpoint of health or hygiene, and it is obliged to install a certain size of window opening in living rooms such as living rooms, dining rooms, kitchens, and bedrooms. .

  Here, the kitchen is a space where food is prepared, prepared, cooked, and also served as a dish and dishwasher after meals. Various kitchen facilities such as a refrigerator, a sink, a heating cooker, and a dishwasher are stored. Storage shelves to do this are indispensable and, therefore, securing window openings is inherently difficult.

  In addition, it is customary for the kitchen to be provided, for example, in the northwest position of the building in consideration of the balance with the living room and dining room, and it is often difficult to capture direct sunlight.

  For this reason, there has been conventionally devised to improve the daylighting performance in the kitchen. For example, the storage shelf arranged along the indoor surface of the outer wall is not fully stored, but is configured so that an opening is formed in the center. A configuration in which window openings are provided at considerable locations is well known.

  However, since the storage space is laid out so as to surround the window opening in the case of the above-described configuration, the operation and the flow line when taking out and storing the tableware are inevitably wasteful, and in the kitchen. There has been a problem that work efficiency is lowered, and storage spaces are concentrated in a high area near the ceiling and a low area near the floor, so that the user experience is poor and the work posture is unreasonable.

  In order to solve such a problem, a device for providing a high window between the storage shelf and the ceiling has been proposed (Patent Document 1). However, since the storage shelf has a large depth dimension in function, However, it is difficult to sufficiently capture natural light, and there is a problem that the storage shelf has to be lowered to solve the problem and the storage space is insufficient.

  The present invention has been made in consideration of the above-described circumstances, and provides a daylighting structure for a building capable of improving daylighting while ensuring rational use of a storage space and sufficient storage space. With the goal.

  In order to achieve the above object, a daylighting structure for a building according to the present invention includes a sloped ceiling having an upward slope from the ceiling of the space in the building located on the indoor side of the outer wall toward the outer wall. In addition, a high window is provided on the outer wall so as to be directly below the sloped ceiling, and the area extending below the high window and in front of the outer wall in the building space is used as an installation space for housing equipment. It is.

  Further, in the building lighting structure according to the present invention, among the columns receiving the load on the upper floor of the building interior space, the arrangement span of the columns erected along the outer wall is parallel to the construction surface including the columns. In addition, the horizontal span of the horizontal member spanned by the pillars erected along the outer wall is separated from the outer wall. It is lower than the beam of the horizontal member that spans the pillars erected on the construction surface.

  Further, the daylighting structure for a building according to the present invention comprises the housing facility as a storage facility, and the storage facility is installed in the installation space so that the top portion is directly below the high window. The upper surface of the top is made of a light reflective material.

  Moreover, the lighting structure of the building which concerns on this invention forms the lower surface of the said gradient ceiling with a light reflective material.

  Further, the daylighting structure for a building according to the present invention is configured such that the housing equipment is installed so that a spacing space extending in a vertical direction is formed between at least a part of the rear surface and the indoor surface of the outer wall. An opening / closing operation means for the high window or a blind attached thereto is disposed in a space, and an operation portion constituting the opening / closing operation means is communicated with the separation space so as to pass from the back side to the front side of the housing facility. It is exposed to the opening provided.

  In the daylighting structure of the building according to the present invention, the ceiling of the interior space of the building located on the indoor side of the outer wall is a sloped ceiling having an upward slope toward the outer wall, and the outer wall is directly below the sloped ceiling. A high window is provided, and an area extending below the high window and in front of the outer wall in the space in the building is set as the installation space for the housing facility.

  In this way, the ceiling height at the outer wall position is increased by the gradient ceiling, and a high window can be provided using the height range, and the height from the floor surface to the lower edge of the high window is normal. It is roughly equivalent to the ceiling height.

  Therefore, it is possible to ensure good daylighting with almost no pressure on the installation space of the housing facility.

  If there is no problem in the installation space of the housing facility, the height size of the high window may be increased in order to improve daylighting. In this case, the height from the floor surface to the lower edge of the high window is lower than the normal ceiling height.

  The sloped ceiling may be appropriately configured by a conventionally known means. Of the columns receiving the load on the upper floor of the space in the building, the construction plane including the columns is an arrangement span of the columns erected along the outer wall. The length of the column is set to be shorter than the span of the column erected on the construction surface that is parallel to the outer wall and separated from the outer wall, and the beam of the horizontal member spanned on the column erected along the outer wall is separated from the outer wall. If the configuration is lower than the beam of the horizontal member spanned on the pillar standing on the surface, it becomes possible to configure the column and the horizontal member with standard materials, and as a result, according to the present invention. The daylighting structure of the building can be constructed at a reasonable cost.

  The space in the building is mainly assumed to be a kitchen, but if it becomes difficult to secure lighting by installing residential equipment, the space can be used arbitrarily, for example, dining, washroom, dressing room, toilet, living room Rooms are also included.

  Residential equipment is arbitrarily configured in relation to space use. If the building space is a kitchen or dining room, the storage shelf mainly stores tableware, etc., and if the building space is a washroom, it is stored. A shelf, a washbasin, or a mirror is applicable, a storage shelf is applicable to a dressing room or a toilet, and a large television or a TV board on which it is installed is applicable to a living room.

  In addition, the housing facilities are not necessarily limited to those installed on the floor surface but also include those fixed to the inner surface of the outer wall.

  When housing equipment is composed of storage equipment such as storage shelves, the storage equipment is installed in the installation space so that the top of the storage equipment is directly under the high window, and the top surface of the storage equipment is formed of a light-reflective material. Then, since the natural light incident through the high window is reflected at the top of the storage facility and sent further forward, the natural light can be spread over the entire space in the building.

  Here, if the lower surface of the sloped ceiling is made of a light-reflective material, the natural light incident through the high window is reflected at the top of the storage equipment and then further reflected by the sloped ceiling. The lighting in the building space is further improved.

  The light-reflective material provided on the top of the storage facility and the light-reflective material on the lower surface of the gradient ceiling are not necessarily limited to metal materials. For example, a plate material with high whiteness can be used as the light-reflective material provided on the top of the storage facility. In addition, cloths with high whiteness are also included in the light-reflective material on the lower surface of the gradient ceiling.

  Whether the high window is a fixed window for daylighting or an open / close window that allows natural ventilation can be selected arbitrarily, and the installation of blinds is also optional, but the high window is used as an open / close window or blinds. When the opening / closing operation is manually performed, a space that extends in the vertical direction is formed between at least a part of the rear surface of the housing facility and the indoor surface of the outer wall. The opening / closing operation means of the high window or the blind attached thereto is disposed in the spaced space, and the operation part constituting the opening / closing operation means is pulled out from the back side to the front side of the housing facility and The structure exposed to the opening provided so that it may communicate with the said separation space is employable.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a daylighting structure for buildings according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a vertical cross-sectional view showing a daylighting structure of a building according to the present embodiment, and FIG. 2 is a view taken in the direction of arrows AA and BB. As can be seen from these drawings, the building lighting structure 1 according to the present embodiment has a sloped ceiling 4 having an upward slope from the ceiling of the kitchen 3 as a space in the building located on the indoor side of the outer wall 2 toward the outer wall 2. The high wall 5 is provided on the outer wall 2 so as to be directly below the sloped ceiling, and the area extending below the high window 5 and in front of the outer wall 2 in the kitchen 3 is set as an installation space on the floor 7. A storage shelf 6 as a housing facility, particularly a kitchen facility, is arranged in the installation space in the form of installation. A refrigerator 15 is installed next to the storage shelf 6.

  The sloped ceiling 4 is attached to the horizontal members 12, 13, and 14 that support the upper floor 8 of the kitchen 3, as can be clearly seen in FIG. The horizontal member 14 is suspended from the horizontal member 14 at a distance, and the horizontal member 13 having the same beam dimension as that of the horizontal member 14 is directly attached to the lower surface thereof. 12 is configured such that an inclined state can be secured by attaching the horizontal member to the lower corner of the horizontal member 13 and 14 after making the beam structure smaller than the horizontal members 13 and 14.

  Here, the horizontal member 12 is stretched over the pillars 11a, 11b, and 11c as shown in FIG. 2 (a), whereas the horizontal member 14 has one end as shown in FIG. 2 (b). It spans between the other pillars not shown in the form joined to the pillars 9 and the horizontal member 13 is connected to the other pillars not shown in the form joined to the pillars 10 in the same manner as the horizontal members 14. The arrangement span of the pillars 11a, 11b, and 11c is between the arrangement span of the pillars 9 and 10 that are erected on the construction surface that is parallel to the construction surface including the pillars and that is separated from the outer wall 2. Even when the beam of the horizontal member 12 is lower than the beam of the horizontal members 13 and 14 in receiving the load of the upper floor 8, the strength is increased by reducing the column arrangement span. The gradient ceiling 4 can be constructed at a reasonable cost without using any material.

  The storage shelf 6 is installed in the above-described installation space so that the top portion 21 is directly below the high window 5. The top portion 21 is formed of a light-reflective material on the top surface, and the high window 5 is The incident natural light is reflected by the top 21 of the storage shelf 6 and sent further forward.

  The light-reflective material can be composed of, for example, an aluminum-based plate material. However, it is optional whether it is specularly reflected or irregularly reflected. If it is desired to irregularly reflect, the above-described aluminum-based plate material is appropriately roughened. You can do it. Further, a plate material with high whiteness may be used as long as a desired reflectance can be obtained.

  Similarly, the lower surface 22 of the gradient ceiling 4 is also made of a light-reflective material. Natural light incident through the high window 5 is reflected by the top 21 of the storage shelf 6 and then further reflected by the lower surface 22 of the gradient ceiling 4. By doing so, incident light can be sent further forward.

  The light-reflective material used for the lower surface 22 of the gradient ceiling 4 is the same as the light-reflective material provided on the top 21 of the storage shelf 6 and can be composed of, for example, an aluminum-based plate material, but a desired reflectance can be obtained. If there is, it may be composed of a cross with high whiteness.

  In the building daylighting structure 1 according to the present embodiment, the ceiling height at the outer wall position is increased by the sloped ceiling 4, and thus the high window 5 is provided using the height range. In this case, the height from the upper surface of the floor 7 to the lower edge of the high window 5 is substantially equal to the normal ceiling height, and the installation space of the storage shelf 6 is hardly pressed.

  In addition, natural light incident through the high window 5 (sky light when the kitchen 3 is arranged on the north side) is reflected by the top 21 of the storage shelf 6 and then reflected by the lower surface 22 of the gradient ceiling 4 as shown in FIG. In order to be further reflected, the incident light is sent further forward.

  As described above, according to the daylighting structure 1 for a building according to the present embodiment, the ceiling of the kitchen 3 is the slope ceiling 4 having an upward slope toward the outer wall 2 and is directly below the slope ceiling. Since the high wall 5 is provided in the outer wall 2 and the area extending below the high window and in front of the outer wall 2 is used as the installation space for the kitchen equipment, the ceiling height at the outer wall position is increased by the sloped ceiling 4. The high window 5 can be provided by using the range.

  Therefore, it is not possible to install high windows with sufficient window openings for kitchen equipment such as storage shelves, and there is no situation where lighting is sacrificed, and sufficient natural light can be taken into the kitchen 3 It becomes.

  Moreover, since the height from the upper surface of the floor 7 to the lower edge of the high window 5 is substantially equal to the normal ceiling height, it is sufficient for the kitchen equipment installed in the installation space, particularly the storage shelf 6. It is possible to provide capacity, and it is not necessary to provide a window opening near the center, so there is no waste in the operation and flow line when taking out and storing tableware, and there is a low area near the high area and floor 7. The storage space is not concentrated in the area, and the work efficiency in the kitchen 3 can be greatly improved.

  Further, according to the daylighting structure 1 of the building according to the present embodiment, the arrangement span of the columns 11a, 11b, and 11c along the outer wall 2 is parallel to the surface including the columns and separated from the outer wall 2. The beam span of the horizontal member 12 is made lower than the beam members of the horizontal members 13 and 14 while using a material having high strength. The sloped ceiling 4 can be constructed at a reasonable cost without any problems.

  Moreover, according to the lighting structure 1 of the building which concerns on this embodiment, while comprising the upper surface of the top part 21 which comprises the storage shelf 6 with a light reflective material, the lower surface 22 of the gradient ceiling 4 is comprised with a light reflective material. As a result, the natural light incident through the high window 5 can be reflected by the top 21 of the storage shelf 6 and then further reflected by the lower surface 22 of the gradient ceiling 4. Can be sent.

  In the present embodiment, the housing facility installed in the installation space is a kitchen facility, particularly a storage shelf 6 that can be stored in its entirety, but the configuration of the storage shelf is arbitrary, as shown in FIG. Storage shelves with various layouts can be used, such as those equipped with counters, and kitchen equipment other than storage shelves, such as a system kitchen incorporating a sink or a heating cooker, may be installed.

  Moreover, in this embodiment, although the space in a building was made into the kitchen 3, it replaces with this and a dining room, a washroom, a dressing room, a toilet, etc. may be used as the space in a building of this invention.

  In this case, if the space in the building is a dining room, the housing equipment will be a storage shelf, if it is a washroom, the housing equipment will be a storage shelf, wash basin or mirror, and if it is a dressing room or toilet, the housing equipment will be a storage shelf. Can do.

  Even in such a configuration, it is the same as the above-described embodiment that the daylighting can be improved without impairing the function of the housing facility.

  Further, in the present embodiment, the columns 9a, 11b, and 11c along the outer wall 2 are arranged so that the spans of the columns 9a and 11b are erected on a plane parallel to the plane including the columns and separated from the outer wall 2. The beam span of the horizontal member 12 is made lower than the beam members of the horizontal members 13 and 14 while being shorter than the arrangement span of 10, but how the sloped ceiling 4 is constructed is arbitrary, It is possible to construct by appropriately adopting known structures and construction methods.

  Moreover, in this embodiment, although the upper surface of the top part 21 which comprises the storage shelf 6, and the lower surface 22 of the gradient ceiling 4 were comprised with the light-reflective material, it replaced with this and only the upper surface of the top part 21 which comprises the storage shelf 6 is comprised. May be made of a light-reflective material.

  Even in such a configuration, the natural light incident through the high window 5 is reflected by the upper surface of the top portion 21 constituting the storage shelf 6, and as a result, the incident light is sent into a certain range of the kitchen 3.

  In addition, as long as sufficient lighting can be obtained, the above-described configuration using the light reflective material in the present embodiment may be omitted.

  Although not particularly mentioned in the present embodiment, when the high window 5 is an opening / closing window and the opening / closing operation is performed manually rather than electrically, the storage shelf 6 is replaced as shown in FIG. A storage shelf 43 formed in the vicinity of the center so that a groove 41 extending in the vertical direction is formed on the back surface and a rectangular opening 42 extending from the back surface to the front surface is communicated with the groove 41 is used as the installation space described above. May be installed.

  The rectangular opening 42 can be used as a counter space on which cooking utensils such as a rice cooker, a toaster, and a mixer are placed. In this modification, when the storage shelf 43 is installed in the installation space described above, A groove 41 provided in the outer wall 2 is a vertically spaced space formed between the interior surface of the outer wall 2 and an operator 44 as an opening / closing operation means for opening and closing the high window 5 is disposed in the spaced space. The handle 45 as an operation unit for operating the operator is exposed to the rectangular opening 42 of the storage shelf 43.

  In this way, the high window 5 can be easily opened and closed by turning the handle 45.

  By using the high window 5 as an opening / closing window, natural ventilation is possible, and heat from a gas stove, microwave oven, toaster or other heat source installed in the kitchen 3 is quickly discharged.
