Description

  The present invention relates to a house (or a part thereof) in which at least a part of the roof is a gable roof, and a residential space for at least two layers is provided below the gable roof.

  In medium- and small-scale two-story buildings, it is common to arrange the floor and ceiling height (floor height) for each level due to structural requirements. However, in houses built in urban areas, the floor must be shifted by half a floor in order to secure as much room and storage space as possible, even though there is not enough room for the site area. There is. When this skip floor is employed, the limited indoor space can be effectively utilized by three-dimensionally arranging a living room and an underfloor storage space that is half a floor high.

  In addition, a configuration in which a loft with a low ceiling height is provided by using a hut with a sloped roof and used for storage, a hobby room, or the like is also well known. These technical ideas are disclosed in, for example, Patent Documents 1 to 3 and the like.

Japanese Patent Laid-Open No. 7-54402 Japanese Patent Laid-Open No. 7-62900 JP 2002-364189 A

  When building a building, the building area law determines the area and height of a building that can be built on the site in the area according to the use area specified by the City Planning Act. Among those areas of use, especially in the first-class or second-class low-rise residential areas, in order to maintain a good living environment, there are strict restrictions on the height and diagonal lines of the building. The degree of freedom in arrangement and roof shape is greatly restricted.

  Under such site conditions, even if it is attempted to employ a skip floor as disclosed in the above-mentioned patent document, it is difficult to secure a sufficient ceiling height on each floor, so that indoor comfort is difficult to obtain. Moreover, even if a loft is provided in the back of a hut, it becomes a cramped space with a low ceiling, and its use tends to be limited.

  Furthermore, since the height of each part of the building is made to correspond to the oblique line restriction, a part of the roof may become an unnatural shape and the appearance may be unbalanced, or harmony with the cityscape may be impaired.

  The present invention has been made in view of such circumstances, and particularly with respect to a house built on a site with severe restrictions on the height and oblique lines of the building, the appearance is a compact two-story building with a suppressed height. The present invention proposes a space configuration in which a three-dimensional sense of expanse and openness can be obtained in the interior living room space, and a storage space can be easily secured.

In order to achieve the above-described object, the housing of the present invention includes a first floor, a second floor that is provided so as to overlap a part of the upper area of the first floor, and that continues from the first floor through stairs and the like, and the second floor From the second floor to the position approximately half a floor higher than the second floor in a skip-like manner, and the second floor and the second floor above the second floor, and the second floor and the second floor. The second floor and the second high floor are arranged so as to change the height of the floor along the ridge direction of the gable roof, and The second floor is provided so as to cover the front of the gable roof along at least one gable surface of the gable roof, and directly supports the gable roof ridge on the floor structure of the second floor. Due to the standing pillars, the upper area of the second floor is a small part of the gable roof. The set of lower chord member is made and the attic space free beam does not cross the region, the high second floor of the upper space is integrated with the attic space, the ceiling of the space along the slope of the gable roof A sloped ceiling, and a window that opens in the vertical direction from the vicinity of the floor of the second floor to the height of the gust is provided on the wife surface above the second floor . Adopt the configuration.

According to this configuration, while keeping the height of the entire building at a standard two-story height, along one wife face, an open space with a ceiling height higher than usual is provided on the first floor and the second floor. It becomes possible to provide it on the floor. Furthermore, the high ceiling space and the other rooms continue in a skip shape along the ridge direction of the gable roof, so that a feeling of spreading in the vertical direction is formed throughout the room.
In addition, since a built-in column that supports the sloped roof ridge directly on the floor structure of the second floor, the building structure with a pentagonal view can be stably supported even if the lower chord material of the hut is omitted. It becomes possible to do. As a result, the upper region of the second floor can be made into a non-beam space where the lower chord material of the hut set constituting the gable roof does not cross the region, so the comfortability and comfort of the second floor space is Further improvement.
Furthermore, by providing a tall window that opens in the vertical direction from the vicinity of the floor of the second floor to the height of the gust on the wife surface above the second floor, The high ceiling space can be made brighter and fuller.

More specifically, the floor of the second floor is provided at a position 1.0 m to 1.5 m higher than the floor of the second floor, and the ceiling height of the first floor is below the second floor. 2.1m to 2.7m, 3.1m to 4.2m below the 2nd floor, and the eave height of the gable roof is 6.0m to 6.7m. A mode in which the height is 10.0 m or less can be employed.

  According to such a configuration, even in a site where the oblique line restriction and the height restriction are severe, a high ceiling space having a ceiling height 1.3 to 1.5 times that of a standard living room is provided in an overlapping manner, and the roof of the building is provided. The appearance related to the shape and the wall surface shape can also be well-balanced.

  In addition, a window having the same width as the window provided above the second floor is also provided on the wife surface located between the second floor and the second floor. Can be provided.

Furthermore, the house according to the present invention includes a hut back floor that overlaps above the second floor in a skip-like manner from the second floor to a position higher than the second floor, and the ceiling of the second floor is It can also be a sloped ceiling along the slope of the gable roof.

  The house of the present invention adopts a spatial configuration that combines a skip floor in which the height of the floor surface is changed approximately half a floor along the ridge direction, and a sloped ceiling along the slope of the gable roof. While having a standard two-story height, it is possible to provide a high ceiling space that overlaps the upper and lower layers along one end face. These high ceiling spaces become an open and bright living space having a ceiling height 1.3 to 1.5 times that of a normal living room. Furthermore, the high ceiling space and the other rooms continue in a skip shape, so that a feeling of spreading in the vertical direction is formed throughout the room.

  Moreover, in a house where families of different generations live in various ways, the form required for the ceiling of the room is diversified according to the use and size of the room. For example, a living room is generally preferred for a high ceiling. The children's room and hobby room also enjoy a sloping ceiling, and the ceiling of the storage room is acceptable even if it is somewhat low. According to the house of the present invention, a change in the ceiling height and shape of each floor is produced by a spatial configuration combining a floor surface and a sloped ceiling that skips approximately half a floor. Therefore, it is possible to create an attractive and varied living space by rationally arranging the individual rooms according to them.

  In addition, by adopting the spatial configuration as described above, while maintaining a well-balanced building exterior without unnaturally deforming the shape of the roof and wall, even on sites with severe restrictions on diagonal lines and heights A sufficient area of living space can be secured indoors.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 10 show a house 1 according to an embodiment of the present invention.

The example house 1 is assumed to be built on a substantially flat site having a site area of about 140 to ²⁰⁰ m ² located in a first-class or second-type low-rise residential area in an urban area or a suburban area. . In FIG. 1, the right side in the drawing of the site is in contact with the front road R, and the other three sides are in contact with the adjacent land.

  This house 1 is built so as to fit in a standard two-story height by, for example, a wooden frame construction method. 1 to 3 show a planar configuration of each floor, and FIGS. 4 to 7 show a configuration of each part of the building in the height direction.

  This house 1 has a gable roof 12 that flows down from one ridge 11 to both sides. The slope of the gable roof 12 is, for example, 6/10 (6 inch slope), and a part of the roof on one side (right side in FIG. 6) is lowered slightly below the height of the standard eaves on the second floor. Yes.

  As shown in FIGS. 1 to 2, the planar shape of the building main body portion is substantially L-shaped, the ridge 11 is arranged in a direction orthogonal to the front road R, and the narrower end face 13 faces the front road R. doing. The front end of the end face 13 on the front road R side is about 6 m, and the front end of the end face 14 including the downside portion on the opposite side is about 8 m. The elevation view of FIG. 6 represents the external appearance of the narrowed front face 13 from the front road R side.

  The floor of the first floor (1F) is approximately 0.5 m above the ground level of the site and is provided at approximately the same level. On the first floor, there are an entrance hall 101, a living room 102, a dining room 103, a kitchen 104, a Japanese-style room 105, a bathroom 106, a bathroom undressing room 107, a toilet 108, a container 109, and the like. The living room 102 is disposed facing the wife surface 13 on the front road R side, and is spatially integrated with the dining room 103 and the kitchen 104. Between the Japanese-style room 105 and the toilet 108, there is a staircase 110 that leads to the second floor (2F).

  The floor surface of the second floor is arranged so as to overlap a part of the upper area of the first floor. The floor of the second floor is provided at a position approximately 3.0 m higher than the floor of the first floor, and the ceiling height of the first floor immediately below the second floor is about 2.5 m. On the second floor, there are a staircase hall 201, a Western room 202 used as a main bedroom, a walk-in closet 203, a study corner 204, a toilet 205, and the like. An atrium 206 is located above the living room 102 on the first floor. A second-floor storage room 207 is provided above the entrance hall 101 on the first floor.

  This second floor is continued to the second higher floor (H2F) provided at a position higher by about half a floor through the skip stairs 208. The floor surface of the high second floor, which is substantially equivalent to the 2.5th floor, covers the atrium 206 on the upper side of the living room 102 and the second floor storage room 207 so as to cover the front surface R side of the front surface R side. Are arranged as follows. The floor of the second floor is provided at a position approximately 1.3 m higher than the floor of the second floor, and the ceiling height of the first floor immediately below the second floor is about 3.8 m.

  Further, the ceiling height of the second floor storage room 207 provided at a position where the floor surface of the second floor is partially overlapped with the second floor is about 1.0 m. In addition, the storage room provided using the floor under the skip floor in this way has a ceiling height of 1.4 m or less, its horizontal projection area is less than 1/2 of the floor area of the floor (the second floor), and directly below If it is less than half of each floor area of the first floor (first floor) and the directly upper floor (higher second floor), the floor area is not included in principle. (Handling may vary depending on the local government.)

  On the second floor, a staircase hall 301, a Western-style room 302, a container 303, 304 and the like are provided. The Western room 302 is arranged so as to cover the front face of the wife surface 13 including the portion directly under the ridge 11, and is used as a child room, for example. The ceilings of the Western room 302 and the storage bins 303 and 304 are formed into a ship-bottomed sloped ceiling (a prayer ceiling or a house-shaped ceiling) along the slope of the gable roof 12 and are integrated with the back of the gable roof 12. The height of the ceiling is about 1.6 m near both ends of the end face 13 and about 3.3 m just below the ridge 11. Since the ceiling portion of the western portion 302 has a large ceiling height, when the western portion 302 is used as a child's room, the room is appropriately partitioned by placing a bunk bed in the central portion according to the growth situation of the child. It becomes possible.

  The second floor is continuous to the back of the hut (LF) through the skip stairs 305 installed immediately below the ridge 11. The floor of the back of the hut is provided at a position about 1.5 m higher than the floor of the second floor, and the ceiling height of the second floor immediately below the back of the hut is about 2.5 m. On the back floor of the hut, there is a shed storage room 401 having a frontage of about 3.0 m centering directly under the ridge 11. The ceiling of the attic storage room 401 is also a sloped ceiling along the slope of the gable roof 12, and the height of the ceiling is about 0.9 m on both sides in the flow direction of the roof and about 1.8 m just below the ridge 11. .

  As for the height of each part of the building from the ground surface in FIG. 5, the height of the floor surface of the first floor (1F) is about 0.5 m, and the height of the floor surface of the second floor (2F) is about 3.5 m. The height of the second floor (H2F) is about 4.8m, the eaves height (up to the upper surface of the eaves girder 15 supporting the hut assembly) is about 6.5m, up to the ridge 11, which is the top Will be about 8.3m high.

  FIG. 7 is a diagram schematically showing the configuration of the floor surface of each floor of the house 1. In this way, by adopting a spatial configuration that combines a skip floor in which the height of the floor surface is changed approximately half a floor along the direction of the ridge 11 and a sloped ceiling along the slope of the gable roof 12, Can be provided with a high ceiling space (the first-floor living room 102 and the second-floor Western room 302) that overlaps the upper and lower two layers along one end face 13 while having a standard two-story height. become. These high ceiling spaces have a ceiling height 1.3 to 1.5 times higher than that of a standard two-story building and are full of openness. Furthermore, the high ceiling space and the other rooms continue in a skip shape, so that a feeling of spreading in the vertical direction is formed throughout the room.

  By the way, when a hut structure with a triangular cross-section is mounted on a wooden framed frame, usually a shed beam, a land beam, a connecting beam, etc. are located at the base of the triangle, as schematically shown in FIG. The lower chord material 91 called is bridged to prevent the both ends of the triangle from opening. Then, the bundle members 92 and 93 are erected on the lower chord member 91 to support the purlin 94 arranged at the apex of the triangle and the gradient beam 95 installed on the hypotenuse of the triangle. However, if such a structure is adopted, the lower chord material 91 crosses the ceiling portion of the space immediately below the cabin set.

  Therefore, in this house 1, in order to further enhance the open feeling of the space on the second floor, as shown in FIG. 8B, the built-in column 97 is placed on the floor construction surface 96 that supports the floor surface on the second floor. A structure that directly supports the purlin 94 is adopted. By bearing a vertical load (compressive load and tensile load) acting on the roof with the ridged column 97, the pentagonal construction surface is stably held, and the triangular lower chord material 91 can be omitted.

  In the house 1 according to the embodiment, as shown in FIGS. 3 and 9, the ridged pillar 17 is disposed at the center of the wife surface 13 and at a position about 3 m away from the center along the ridge 11. The floor structure surface 33 on the second floor (H2F) on which the ridged pillar 17 is erected is constructed so as to overlap the floor structure surface 32 on the second floor (2F). The surrounding floor beam 24 and the floor beam 25 surrounding the floor construction surface of the second floor are integrally coupled via a short column member 18 or a stiffening surface material (not shown), so that A bearing wall 36 is formed between the second floor. By adopting such a double floor structure, it is possible to realize a non-beam space where the lower chord material of the hut set does not cross the ceiling space in the upper region of the second floor.

  The floor structure of the back of the hut (LF), which is approximately half a floor higher than the 2nd floor, is supported by a hut beam 16 (see FIG. 9) that is installed at the height of the lower chord of the hut assembly. Has been.

  Furthermore, in the illustrated house 1, a vertically long window 51 reaching the height of the breaking wind is provided on the end face 13 in order to ensure sufficient lighting and ventilation in the space on the second floor. Here, “the height of the blast” is a position higher than at least a line that horizontally connects the eaves girder 15 (the base of the triangle of the roof set: see FIG. 5). As shown in FIGS. 9 and 10, the window 51 stands with the built-in column 17 standing directly below the building 11 on the end face 13 and on both sides of the built-up column 17 with an interval of about 1 m. It is assembled between the wife face sub-column 19 provided. The wife face sub-column 19 is also supported by the floor structure surface 33 on the second floor, like the ridged pillar 17, and its upper end is joined to the gradient beam 21 on the upper face of the wife face 13 in a column winning manner. By adopting a structure in which the lower chord material does not cross the bottom of the hut assembly, the window 51 is a window having continuity in the vertical direction in which an intermediate portion is not divided by the shed beam or other structural material. By providing such a tall window in the center of the wife surface 13, a space that is much brighter and more open is created on the indoor side of the wife surface 13. If the window 51 can be opened and closed, sufficient ventilation can be obtained. Note that the opening surface of the window 51 being divided into a plurality of portions by a glass shoddle frame or the like fitted into the window 51 does not impair the overall continuity of the window 51.

  Further, on the wall surface of the end face 13 other than the window 51, that is, between the end face pillar 19 and the side pillars 23 erected at both corners of the end face 13, a wall surface having a width of about 2 m is appropriately provided. Are connected to each other, and a stiffening surface material such as a structural plywood is stretched to form a bearing wall 35 sandwiching the window 51 from the left and right. As a result, the in-plane rigidity of the end face 13 is improved, and the pentagonal building frame having the gable roof 12 becomes stronger.

  The window 51 of the end face 13 can be extended downward to the vicinity of the floor surface on the second floor. That is, if the bearing wall 36 provided between the floor structure surface 33 on the second floor and the floor structure surface 32 on the second floor is arranged so that the width is aligned with the portion above the second floor, the second floor A short window 52 having the same width as that of the above-described window 51 can also be provided in a portion between the second floor. This window 51 further enhances the feeling of opening of the living room 102 on the first floor. The window 52 and the window 51 above the second floor are structurally divided by the floor beam 24 that supports the floor structure surface 33 on the second floor, but in terms of appearance, Can be made to have the impression of being integrated vertically.

  As shown in FIG. 4, the multi-layered structure that connects the indoors in the direction of the ridge 11 as shown in FIG. 4 by the combination of the height window 51 provided in the center of the wife face 13 and the above-described space configuration using the skip floor. A wind path W is formed to improve the ventilation of the whole indoor space. Further, the external light S can be introduced from the window 51 provided at a high position of the wife surface 13 to the back of the house 1. As a result, even in a relatively small site in an urban area, it is possible to realize a comfortable living space that is bright and open, and that makes it easy to experience the rich natural itch.

  In addition, embodiment mentioned above is an example, About the planar shape, floor plan, etc. of each floor | bed, it can change suitably in the range which does not deviate from the main point of this invention. Regarding the height relationship of each part of each floor, it is possible to increase or decrease by several tens of centimeters within the range that does not impair the actual comfortability, etc., using the dimensions of the exemplary form as a guide. (As a general rule, the exact height of each part of the building shall be in accordance with the provisions of the Building Standards Act.)

  Further, the present invention is applied to a two-story equivalent part in a house where a two-story equivalent part having a gable roof is provided in at least a part of the building. The structure and space configuration are not particularly limited. Further, if the roof shape of the two-story equivalent part is a double-sloped slope roof similar to a gable roof, for example, a folded back roof (mansard roof) or a kamaboko-shaped arch roof (vault roof) Applicable.
