The embodiments described below are merely examples of the present invention, and it goes without saying that the embodiments of the present invention can be appropriately modified without departing from the scope of the present invention.

  The housing 10 of the present embodiment is shown in FIG. The frame 10 is a frame of a low-rise wooden structure such as a wooden house.

  The frame 10 is configured by combining a plurality of two-way wooden rigid frame structures 11 shown in FIG. That is, according to the shape of the housing 10, a plurality of wooden two-way rigid frame structures 11 are appropriately combined. The basic structure of each wooden two-way rigid frame structure 11 is the same, so in the following, the wooden two-way rigid frame structure 11 shown in FIG. 2 will be described as an example. In addition, below, "a wood two-way ramen structure 11" is only described as "the ramen structure 11."

  The rigid frame structure 11 includes a foundation 20 which is a cloth foundation, wooden columns 51 to 59, wooden beams 61 and 62, spacers 71 to 76 (FIGS. 4, 6 and 8), and fasteners 81 to 90 (FIG. 4, 6, 8).

  The foundation 20 includes a first foundation 21, a second foundation 22, a third foundation 23, and a fourth foundation 24. The first base 21, the second base 22, the third base 23, and the fourth base 24 have the same shape. The base portions 21 to 24 each have a base portion 25 provided on the horizontal base surface 12 and a rising portion 26 projecting upward from the base portion 25. The rising portion 26 has an upper surface supporting a wall or pillars 51 to 59 (not shown). Specifically, the first base portion 21 has a first upper surface 21A, the second base portion 22 has a second upper surface 22A, and the third base portion 23 has a third upper surface 23A. The fourth base portion 24 has a fourth upper surface 24A.

  Each of the upper surfaces 21A to 24A has a constant width along one direction. Specifically, the first base portion 21 and the fourth base portion 24 are provided along the first direction 13 along the horizontal plane. The second base portion 22 and the third base portion 23 are provided along a second direction 14 orthogonal to the first direction 13 on a horizontal surface. The first upper surface 21A and the second upper surface 22A intersect at the first projecting corner portion 31. The first upper surface 21A and the third upper surface 23A intersect at the second projecting corner portion 32. The second upper surface 22A and the fourth upper surface 24A intersect at the third projecting corner portion 33. In other words, the first upper surface 21A of the first base portion 21 extends from the first exit corner 31 to the second exit corner 32 with a constant width, and the second exit corner 32 has a fourth foundation. It intersects with the third upper surface of the portion 24. The second upper surface 22A of the second base portion 22 extends with a constant width from the first exit corner portion 31 to the third exit corner portion 33, and in the third exit corner portion 33, the second upper surface 22A 4 intersects with the top surface 24A. The third upper surface 23A of the third base portion 23 extends from the other protruding corner portion toward the second protruding corner portion 32 with a constant width, and in the second protruding corner portion 32, the first upper surface 23A of the first base portion 21 is formed. It intersects with the upper surface 21A. The fourth upper surface 24A of the fourth base portion 24 extends with a constant width from the other protruding corner portion to the third protruding corner portion 33, and in the third protruding corner portion 33, the second upper surface 24A of the second base portion 22 It intersects with the top surface 22A.

  The first projecting corner portion 31 supports the first column group 41. The second raised corner portion 32 supports the second column group 42. The third projecting corner portion 33 supports the third column group 43. The first column group 41 supports one end of a first beam 61 and a second beam 62 described later. The second column group 42 supports the other end side (the central portion in the illustrated example) of the first beam 61. The third column group 43 supports the other end side of the second beam 62. That is, the first beam 61 extends in the first direction 13 and the second beam 62 extends in the second direction 14. Therefore, the ramen structure 11 is a so-called two-way woody ramen.

  Each pillar group 41 to 43 includes three pillars respectively. Specifically, as shown in FIGS. 3 and 4, the first pillar group 41 includes a first pillar 51, a second pillar 52, and a third pillar 53. As shown in FIGS. 5 and 6, the second column group 42 includes a fourth column 54, a fifth column 55, and a column 58. As shown in FIGS. 7 and 8, the third pillar group 43 includes a sixth pillar 56, a seventh pillar 57, and a pillar 59.

  The columns 51 to 59 are long square prisms extending in the vertical direction 15, and all have the same shape. As shown in FIG. 3, the length L of one side of the bottom surfaces of the columns 51 to 59 is slightly shorter than the width W3 of the top surfaces 21A and 22A. That is, the columns 51 to 59 can be disposed on the upper surfaces 21A to 24A and the upper surfaces of the protruding corner portions 31 to 33.

  Describing specifically, the columns 51 to 59 are mounted on column pedestals (not shown) disposed on the upper surfaces 21A to 24A. That is, the columns 51 to 59 are indirectly supported by the foundation 20 via the column base fitting. The column and leg fitting is fixed to the base 20 by, for example, an anchor bolt and a nut protruding upward from the upper surfaces 21A to 24A. The column base fitting and the lower ends of the columns 51 to 59 are coupled by, for example, a pin. That is, the columns 51 to 59 are fixed to the foundation 20 via the column and leg fittings. A foundation may be provided on the foundation 20 in place of the column and leg fitting. The base is fixed to the upper surface of the base 20 by, for example, the above-described anchor bolt. The base and the columns 51 to 59 are coupled, for example, by fasteners.

  Hereinafter, the columns 51 to 53 of the first column group 41 will be described. The first pillar 51 is disposed on the upper surface of the first projecting corner portion 31 which is the intersection position of the first upper surface 21A and the second upper surface 22A. The second pillar 52 is disposed on the first upper surface 21A so as to be separated from the first pillar 51. The separation distance D1 between the first column 51 and the second column 52 is such that the width W2 of the second beam 62 can be held so that the second beam 62 can be sandwiched between the first column 51 and the second column 52. And the same. The third pillar 53 is disposed on the second upper surface 22A so as to be separated from the first pillar 51. The separation distance D2 between the third column 53 and the first column 51 has a width W1 of the first beam 61 so that the first beam 61 can be sandwiched between the first column 51 and the third column 53. And the same. As described later, since the first beam 61 and the second beam 62 have the same width, the width W1 and the width W2 are the same. Therefore, the separation distance D1 and the separation distance D2 are also the same.

  The separation distance D1 is secured by the first spacer 71 inserted between the first column 51 and the second column 52. Specifically, the first spacer 71 has a quadrangular prism shape shorter than the first pillar 51. The first spacer 71 is, for example, wooden. The width W4 (FIG. 4) of the first spacer 71 is the same as the width W2 of the second beam 62. The first spacer 71 is disposed between the first pillar 51 and the second pillar 52 on the lower end side of the first pillar 51 and the second pillar 52, and the fifth fastener 85 causes the first pillar 51 and the second pillar Attached to 52.

The first spacer 71 is fixed to the first post 51 and the second post 52 by the fifth fastener 85 while being sandwiched between the first post 51 and the second post 52. The first spacer 71 sandwiched between the first column 51 and the second column 52 keeps the separation distance D1 between the first column 51 and the second column 52 constant in the vertical direction 15. That is, the first spacer 71 prevents the upper end of the first pillar 51 and the upper end of the second pillar 52 from opening and narrowing more than necessary. In addition, the first spacer 71 inserted between the first column 51 and the second column 52 enhances the strength of the rigid frame structure 11. The fifth fastener 85 may not be a metal plate as long as the first spacer 71 can be fixed to the first pillar 51 and the second pillar 52, and other types of fasteners may be used. For example, the fifth fastener 85 may have the same configuration as the fastener 91 described later. The same applies to the other fasteners 86 to 90 described below.

  The separation distance D2 between the first column 51 and the third column 53 is secured by the second spacer 72 inserted between the first column 51 and the third column 53. The second spacer 72 is, for example, wooden. The second spacer 72 has the same shape as the first spacer 71, and is held between the first pillar 51 and the third pillar 53 by the sixth fastener 86 having the same configuration as the fifth fastener 85. It is fixed to the pillar 51 and the third pillar 53.

  The second spacer 72 keeps the separation distance D2 between the first pillar 51 and the third pillar 53 constant in the vertical direction 15, and enhances the strength of the rigid frame structure 11. The fifth fastener 85 and the sixth fastener 86 may be integrated. That is, an L-shaped metal plate may be used as the fifth fastener 85 and the sixth fastener 86.

The sixth pillar 56 is disposed on the upper surface of the third projecting corner portion 33, which is an intersection position of the second upper surface 22A and the fourth upper surface 24A. The seventh pillar 57 is disposed on the fourth upper surface 24A so as to be separated from the sixth pillar 56 and to face the second pillar 52 (FIG. 3) in the second direction 14. The pillars 59 are disposed on the second upper surface 22A so as to be separated from the sixth pillars 56. In addition, the below-mentioned beam 64 fixed to the pillar 59 is not a part of rigid-frame structure 11 shown by FIG. 2, but is a part of other rigid-frame structure which comprises the frame 10. As shown in FIG. Thus, the detailed description of the beam 64 is omitted.

  The separation distance between the sixth column 56 and the seventh column 57 is the same as the width of the second beam 62 so that the second beam 62 can be sandwiched between the sixth column 56 and the seventh column 57. It is assumed. The separation distance between the sixth column 56 and the column 59 is equal to the width of the beam 64 so that the beam 64 can be sandwiched between the sixth column 56 and the column 59. The second beam 62 and the beam 64 have the same width, and the distance between the sixth column 56 and the seventh column 57 and the distance between the sixth column 56 and the column 59 are the same. is there.

  The separation distance between the sixth column 56 and the seventh column 57 is secured by the fourth spacer 74 inserted between the sixth column 56 and the seventh column 57. The fourth spacer 74 is, for example, wooden. The shape of the fourth spacer 74 is the same as the shape of the first spacer 71. The fourth spacer 74 is disposed between the sixth pillar 56 and the seventh pillar 57 on the lower end side of the sixth pillar 56 and the seventh pillar 57, and the eighth fastener 88 causes the sixth pillar 56 and the seventh pillar Attached to 57 The shape of the eighth fastener 88 is the same as the shape of the fifth fastener 85.

[Function effect]
In the present embodiment, the first pillar 51, the fourth pillar 54, and the sixth pillar 56 are disposed at the projecting corner portions 31, 32, 33, respectively. The second pillar 52 is disposed on the first upper surface 21A. The third pillar 53 is disposed on the second upper surface 22A. The fifth column 55 is disposed on the third upper surface 23A. The seventh pillar 57 is disposed on the fourth upper surface 24A. Therefore, the rigid frame structure 11 can be configured using the conventional foundation 20 having the top surfaces 21A to 24A of a constant width. That is, the rigid-frame structure 11 can be comprised, even if it does not use the base of a different structure, such as enlarging the projecting corner parts 31-33. In addition, since the columns 51 to 59 are provided on the upper surfaces of the upper surfaces 21A to 24A, the columns 51 to 57 do not protrude from the wall or the wall is not thickened. Further, since the beams 61 and 62 and the columns 51 to 57 are directly fastened, members such as end members are unnecessary.

In addition, the same code | symbol is attached | subjected to the structure similar to the above-mentioned embodiment, and description is abbreviate | omitted.

  The wood two-way rigid frame structure 16 includes a foundation 27, column groups 41 to 43, beams 61 and 62, and a wooden eighth column 60.

  The base 27 is different from the base 20 in that the base 27 includes the projecting portion 28. The overhanging portion 28 is provided at a position immediately below an intermediate position in the longitudinal direction (second direction 14) of the second beam 62. The overhanging portion 28 has an upper surface 28A projecting in the width direction from the second upper surface 22A of the second base portion 22. The second upper surface 22A and the upper surface 28A are flush with each other. That is, the upper surface 28A is along the horizontal plane. The upper surface 28A is attached with the column base fitting described in the above embodiment. The eighth column 60 is mounted on and fixed to the column base fitting.

  In the illustrated example, the eighth column 60 is in the shape of a long square in the vertical direction 15. The length of the eighth column 60 in the vertical direction 15 is substantially the same as the distance from the upper surface 28A of the overhang 28 to the lower surface of the second beam 62. The eighth column 60 is disposed with its lower end in contact with the column base fitting and its upper end in contact with the lower surface of the second beam 62. The upper end of the eighth post 60 is coupled to the second beam 62 using a mounting bracket (not shown). The eighth column 60 may have the same thickness as the columns 51 to 59, or may be thinner than the columns 51 to 59. The eighth column 60 may have a long cylindrical shape which is long in the vertical direction 15.

  The eighth column 60 prevents the second beam 62 from being bent or the like. The eighth pillar 60 is provided, for example, when the length of the beam exceeds a certain length.

  Although the above-mentioned embodiment explained the example where foundation 20 is cloth foundation, foundation 20 may be solid foundation.

  In the above-mentioned embodiment, the example in which the frame 10 was comprised only with the rigid-frame structure 11 was demonstrated. However, the frame 10 may be configured by combining the rigid frame structure 11 and the other structure. For example, the other ends (not shown) of the beams 63 and 64 in the rigid frame structure 11 shown in FIG. 2 may be supported by one column.

  In the above embodiment, an example in which the first upper surface 21A and the second upper surface 22A are orthogonal to each other has been described. However, the first upper surface 21A and the second upper surface 22A may intersect at an acute angle or an obtuse angle. In the case where the first upper surface 21A and the second upper surface 22A intersect at an acute angle or an obtuse angle, for example, the joint between the pillars 51 to 57 with the beams 61 and 62 is chamfered in conformity with the side surfaces of the beams 61 and 62.

  In the above-mentioned embodiment, the example which the 1st beam 61 and the 2nd beam 62 were joined by the lack 61A and 62A was demonstrated. However, the first beam 61 and the second beam 62 may be joined by tenoning or butting. In the case of joining by pushing, the first beam 61 and the second beam 62 are mutually fastened using the above-described reinforcing plate 93 or the like.
