Description

  The present invention relates to a building frame including a wife face of a wooden building (or a part thereof) in which at least a part of the roof is a 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 among buildings and other buildings that are built on a site with severe restrictions on the height and oblique lines of the building, in particular, a building built with a wooden frame structure or a wooden structure equivalent thereto. In this regard, we propose a building frame suitable for realizing a three-dimensional spaciousness and openness in a compact exterior with a reduced height.

In order to achieve the above-mentioned object, the present invention is a wooden building in which at least a part of a roof is a gable roof, and is a pentagonal building structure that includes at least one gable face of the gable roof. The floor structure surface having a rectangular shape in plan view provided on the floor immediately below the gable roof, the side pillars erected at the four corners of the floor structure surface, and the upper ends of the side pillars are connected to each other in the column direction. A pair of eaves girder, a plurality of gradient beams erected from the pair of eaves girder to the gable roof ridge at appropriate intervals, a purlin connecting the top ends of the gradient beams, and the gable A ridged column that is erected at a position directly below the ridge including at least one end face of the roof and directly supports the purlin on the floor structure, and an appropriate interval is provided between the right and left sides of the ridgeline column of the end face. And supports the gradient beam at the top of the wife surface on the floor construction surface. Comprising wife surface sub pillars, and between the Tomochi pillar and each wife face sub pillar of the wife surface, with the continuity of the vertical direction up to the height of the gable wife surface from the floor Plane In addition, a vertical load acting on the gable roof is borne by the ridged pillar so that the lower chord material of the hut group constituting the gable roof does not cross on the floor construction surface. A structure with a beam space formed is adopted.

  According to this configuration, a tall window extending from the vicinity of the floor surface of the floor immediately below the gable roof to the vicinity of the ridge can be provided in the central portion of at least one of the gable roofs. This window is a continuous window in the vertical direction in which an intermediate portion in the height direction is not divided by a roof beam or other structural material. By providing such a window on the wife's face, the indoor side of the wife's face can be made a space that is much brighter and full of openness.

  In addition, by adopting a structure in which the purlin is directly supported on the floor structure by the ridged pillar, it is possible to partially omit the shed beam and the land beam that are the lower chord members of the hut group. Using this structure, if the ceiling of the floor immediately below the gable roof is a sloped ceiling along the slope of the gable roof, a substantial ceiling height can be secured while suppressing the height of the ridge. A comfortable indoor space with a sense of spreading in the vertical direction can be obtained.

  Furthermore, the above-mentioned building frame can be constructed such that a stiffening surface material is stretched at a portion of the end face sandwiched between the side pillar and the end face sub pillar. The portion where the stiffening surface material is stretched serves as a structural load-bearing wall, and improves the rigidity of the end face in the building frame.

  Further, in the above-mentioned building frame, the floor structure surface of the immediately lower floor is supported by the floor beam of the immediately lower floor disposed around the four circumferences, and is approximately half a floor below the floor structure surface of the immediately lower floor. The floor construction surface of the lower floor supported by the floor beam of the lower floor may be provided with a height of less than a minute.

  This structure consists of a floor structure on the floor immediately below the gable roof, and a floor structure on the lower floor provided with a height (approximately 1.0 to 1.5 m as a guideline) below the half floor. The building frame is supported by the double floor structure. The floor structure surface of the directly lower floor and the floor structure surface of the lower floor are structurally integrated, for example, by connecting the floor beams surrounding the four circumferences of each floor structure surface with short column members or face materials. By adopting such a double-floor structure, it is possible to stabilize a pentagonal building frame from the front, omitting the lower chord material of the hut assembly, while suppressing the cross-sectional dimensions of floor beams surrounding the four circumferences of each floor structure. Can be supported. In addition, by providing a skip floor and an underfloor storage using such a double floor, it is possible to utilize the space inside the building in three dimensions.

  And in the building frame that adopts this double floor structure, it is the same as the above-mentioned window that extends from the immediate lower floor to the vicinity of the building in the part between the floor structure on the lower floor and the floor structure on the lower floor. It is also possible to provide a window of width.

  Further, in the above-mentioned building frame, a stiffening surface material is dropped between the gradient beam on the upper surface of the end face and the gradient beam adjacent thereto, and the stiffening surface material is joined to the both gradient beams. Can be. The roof surface on which the stiffening material is stretched reinforces the overall horizontal rigidity of the building frame as a horizontal load-bearing element of the roof. In addition, it is possible to omit a burning member or the like that should be arranged at a corner of the bottom of the hut (joint between a shed beam and an eaves girder, etc.) in a general shed structure.

  The building frame of the present invention employs a structure in which a purlin is directly supported by a ridged column that is erected on the floor structure of the floor immediately below the gable roof, so that the lower string of a hut beam or the like above the floor immediately below. A non-beam space that does not cross the material is formed, and a space configuration with a tall window that extends to the vicinity of the building is possible between the built-up column on the wife surface and the sub-column on the both sides To. As a result, it is possible to create an indoor space that is bright and full of openness and has a feeling of spreading in the height direction in a compact appearance with the height of the ridge suppressed.

  By adopting such a building frame, even in a site with severe restrictions on diagonal lines and height, comfortable living can be maintained while maintaining a balanced building appearance without unnaturally deforming the shape of the roof and walls. Sex can be obtained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 7 and 9 to 11 show a wooden house that employs a building frame 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. Thus, 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, Although it has a standard two-story height, a high ceiling space (a first-floor living room 102 and a two-story western room 302) that overlaps with the upper and lower layers along one end face 13 is provided. It becomes possible. 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.

  The main part of this invention exists in the building frame for implement | achieving such a space. Hereinafter, the building frame of the house 1 according to the embodiment will be described in detail.

  First, when a hut structure with a triangular cross-section is placed on a wooden shaft frame, usually a shed beam, land beam, connecting beam, etc. are located at the bottom 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 the present invention, as shown in FIG. 8B, a ridged column 97 is erected on the floor construction surface 96 on the floor immediately below the gable roof, and the ridged tree 94 is directly supported by the ridged column 97. The structure to be adopted 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 FIG. 9 and FIG. 10, the floor structure surface 33 of the second floor (H2F), which is directly below the gable roof 12, and the four corners of the floor structure surface 33 are erected. Side pillars 23, a pair of eaves girder 15 connected to each other by connecting the upper ends of the side pillars 23 in the direction of the rows, and the two eaves girder 15 from the eaves girder 15 toward the ridge 11, respectively, with the same ascending slope in a palm shape A building frame having a pentagonal shape in front view is formed by a plurality of installed gradient beams 21 and a purlin (building girder) 34 connecting the upper ends of the gradient beams 21 in the direction of the building 11. In addition, as long as this building frame is configured including at least one end face 13 located on the outer periphery of the building, the opposite side end face of the floor structure surface 33 may be continuous with the other part of the building. Further, the side pillar 23 may be a through pillar erected from the first floor, or may be a pipe pillar erected on the floor construction surface 33 of the second floor.

  And the center of the side by the side of the wife surface 13 of the floor construction surface 33 of the second floor, and the ridged pillar 17 erected in the center of the opposite side about 3 m away from the ridge 11 are the purlin 34. The both ends of each are directly supported. In the illustrated embodiment, the lower end of the ridged column 17 is erected in a beam-winning state on the floor beam 24 surrounding the floor structure surface 33 on the second floor, and the upper end of the ridged column 17 is It is joined to the pillar win. However, the lower end of the ridged column 17 may be joined to the floor beam 24 in a column win, and the upper end of the ridged column 17 is joined to the purlin 34 in a sparge win (girder win). Also good.

  The length of the ridged pillar 17 in the illustrated form is 3.3 to 3.4 m, and the cross-sectional shape is substantially square. When the ridged column 17 becomes longer, the wind resistance can be improved by making the cross-sectional shape a rectangle that is long in the ridge 11 direction. In addition, when the length along the direction of the ridge 11 of the floor structure surface 33 on the second floor exceeds 5 m as a guideline, a ridged pillar (not shown) is additionally erected in the middle part of the ridgeline 34. It is preferable to support the middle part of the above.

  On the left and right sides of the built-up column 17 on the wife surface 13, a wife surface sub-column 19 is erected with an appropriate interval (about 1 m in the illustrated embodiment). As with the built-up column 17 of the wife surface 13, the lower end of the wife surface column 19 is also erected in a beam-winning state on the floor beam 24 surrounding the floor structure surface 33 on the second floor. Is joined to the gradient beam 21 at the top of the end face 13 in a column winning manner. However, the lower end of the end face sub-column 19 may be joined to the floor beam 24 in a column win, or the upper end of the end face sub-column 19 may be joined to the gradient beam 21 in a beam win. Good.

  A vertically long window 51 is provided between the built-up pillar 17 of the wife face 13 and each of the wife face sub-columns 19 so as to reach the height of the breaking wind of the wife face 13 from the floor structure surface 33 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). 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.

  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 having a width of about 2 m is appropriately short. The beam 22 and the like are coupled, and a stiffening surface material such as a structural plywood is stretched to form a load bearing wall 35 that sandwiches 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.

  Further, in the residential form 1 in the illustrated form, the second floor (H2F) floor structure surface 33 that supports the ridged pillar 17 and the wife side subcolumn 19 is a lower floor that is approximately half a floor lower than the second floor ( 2F) so as to overlap with the floor construction surface 32. The floor beam 24 surrounding the floor structure surface 33 on the second floor and the floor beam 25 surrounding the floor structure surface 32 on the second floor are integrated with each other via the short column member 18 and a stiffening surface material (not shown). As a result, the bearing wall 36 is also formed between the second and second floors. In this way, by adopting a double floor structure in which the floor beams 24 and 25 that support the floor structure of each floor are stacked in two upper and lower stages, while suppressing the cross-sectional dimensions of the members of the floor beams 24 and 25, etc., the front surface The stability of the building pentagonal view can be further improved. The shaded portions in FIG. 10 indicate portions that become the bearing walls 35 and 36 of the end face 13. 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.

  In the building frame in which the rigidity of the end face 13 is enhanced in this way, the window 51 of the end face 13 described above 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 beams 24 that support the floor structure 33 on the second floor, but in terms of appearance. The impression is continuous with a uniform width in the vertical direction.

  FIG. 11 shows another configuration example of the windows 51 and 52 and the load-bearing walls 35 and 36 provided on the end face 13 of the building frame. In this example, two wives sub-columns 19 are erected at substantially equal intervals (an interval of 0.75 m in the illustrated embodiment) on each of the left and right sides of the built-up column 17, and a total of four places are provided between them. Window 51 is formed. In addition, a total of four windows 52 are formed between the floor structure surface 33 on the second floor and the floor structure surface 32 on the second floor so as to have the same width as the upper window 51. The opening width of these windows 51 and 52 is about 3 m as a whole, and covers about 1/2 of the frontage of the end face 13. A wall surface having a width of about 1.5 m sandwiched between the outer face sub-column 19 and the side columns 23 at both corners is a load bearing wall 35 similar to the above-described embodiment.

  Thus, according to the building frame of the present invention that supports the gable roof 12 by the building column 17 and the load bearing walls 35 provided on both sides of the wife surface 13, in the wife surface 13 whose frontage is approximately within 6 m, In the center, a tall window 51 having a width up to about ½ of the frontage can be provided in a form that does not cross the lower chord material of the cabin set.

  Furthermore, as shown in FIG. 12, this building frame can enhance the horizontal proof stress of the whole frame with respect to wind power etc. by attaching the stiffening surface material 37 to a sloped roof surface. In the form shown in the figure, the gradient beam 21 on the top of the end face 13 joined to the end of the ridge 11 and the second gradient beam 21 from the end face 13 adjacent thereto, and the second gradient beam from the end face 13. 21 and the third graded beam 21 and the fourth graded beam 21 and the fifth graded beam 21 from the end face 13 (located on opposite sides of the floor structure surface 33 on the second floor, which is a no-beam space). Stiffening face materials 37 are attached to a total of three locations between the gradient beams 21) so as to be symmetrical in both flow directions across the ridge 11. However, the arrangement of the roof end other than the stiffening surface material 37 attached along the end face 13 may be appropriately set according to the size of the roof surface, the arrangement interval of the gradient beams 21, and the like.

  The stiffening surface material 37 is made of a structural plywood or the like, and is dropped between the opposing gradient beams 21, and each long side is joined to a receiving member 38 attached to the side surface of each gradient beam 21. . In some cases, the short side of the stiffening surface member 37 may be joined to an appropriate receiving member or the like attached to the purlin 34, the eaves girder 15 or the like.

  As a result of the horizontal component of the entire frame being reinforced by the horizontal component of the stiffening surface member 37 that is fixed to the roof surface in an inclined state, the building frame usually has a corner at the bottom of the hut (in the illustrated embodiment, the short beam 22 and the like). It is possible to omit the fire-fitting member and other reinforcing members attached to the eaves girder 15 and the like. Thereby, the no-beam space formed above the high second floor can be made even cleaner.

  The present invention is applied to a building frame of a part including at least one side of the floor of a floor directly below the gable roof ridge in a building in which at least a part of the roof is a gable roof. The structure of the building frame other than the part is not particularly limited. The level corresponding to the “direct floor” of the gable roof may be substantially the first level, or may be a level of three or more levels. Further, the present invention can be applied not only to a building frame in which the shape of the wife surface is symmetrical with respect to the ridge, but also to a building frame in which the wife surface has a slightly asymmetric shape. Furthermore, the present invention can be applied not only to a building frame having a wooden frame structure, but also to various wooden building frames having a panel structure, a two-by-four structure, or a composite structure of the same. The detailed shape and joining form of the members can be modified as appropriate without departing from the gist of the present invention. Moreover, the use and floor plan of each part of the building are not particularly limited to the illustrated form.
