  Hereinafter, embodiments of the present invention will be described. The embodiment described below is merely an example of the present invention, and it is needless to say that the embodiment of the present invention can be changed as appropriate without departing from the gist of the present invention.

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

  The frame 10 is configured by combining a plurality of wooden bi-directional frame structures 11 shown in FIG. That is, according to the shape of the casing 10, a plurality of woody two-way frame structures 11 are appropriately combined. Since the basic structure of each wooden two-way frame structure 11 is the same, the following description will be made by taking the wooden two-way frame structure 11 shown in FIG. 2 as an example. In the following, the “woody bi-directional ramen structure 11” is simply referred to as “ramen structure 11”.

  The ramen structure 11 includes a foundation 20 that is a fabric 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 ( 4, 6, 8).

  The foundation 20 includes a first foundation part 21, a second foundation part 22, a third foundation part 23, and a fourth foundation part 24. The 1st foundation part 21, the 2nd foundation part 22, the 3rd foundation part 23, and the 4th foundation part 24 are 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 protruding upward from the base portion 25. The rising portion 26 has an upper surface that supports walls and 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, the third base portion 23 has a third upper surface 23A, The fourth base portion 24 has a fourth upper surface 24A.

  Each upper surface 21A-24A has a fixed width and is along one direction. If it demonstrates concretely, the 1st foundation part 21 and the 4th foundation part 24 will be provided along the 1st direction 13 along a horizontal surface. The second base portion 22 and the third base portion 23 are provided along a second direction 14 that is orthogonal to the first direction 13 on a horizontal plane. The first upper surface 21A and the second upper surface 22A intersect at the first protruding corner 31. The first upper surface 21A and the third upper surface 23A intersect at the second protruding corner 32. The second upper surface 22A and the fourth upper surface 24A intersect at the third protruding corner portion 33. In other words, the first upper surface 21A of the first foundation portion 21 extends from the first protruding corner portion 31 toward the second protruding corner portion 32 with a constant width. 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 protruding corner portion 31 toward the third protruding corner portion 33. 4 Crosses the upper surface 24A. The third upper surface 23 </ b> A of the third base portion 23 extends with a constant width from the other protruding corner portion toward the second protruding corner portion 32. Crosses 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 toward the third protruding corner portion 33. Crosses the upper surface 22A.

  The first protruding corner 31 supports the first column group 41. The second protruding corner portion 32 supports the second column group 42. The third protruding 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 (in the illustrated example, the center portion) 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 along the first direction 13, and the second beam 62 extends along the second direction 14. Therefore, the ramen structure 11 is what is called a wooden bi-directional wooden ramen.

  Each of the column groups 41 to 43 includes three columns. Specifically, as shown in FIGS. 3 and 4, the first column group 41 includes a first column 51, a second column 52, and a third column 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 column group 43 includes a sixth column 56, a seventh column 57, and a column 59.

  The pillars 51 to 59 are long regular square pillars along 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 pillars 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.

  Specifically, the columns 51 to 59 are placed on column bases (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 metal fittings. The column base bracket is fixed to the foundation 20 by, for example, anchor bolts and nuts protruding upward from the upper surfaces 21A to 24A. The column base metal and the lower ends of the columns 51 to 59 are coupled by, for example, pins. That is, the columns 51 to 59 are fixed to the foundation 20 via the column base metal fittings. Note that a foundation may be provided on the foundation 20 instead of the column base metal fittings. The base is fixed to the upper surface of the foundation 20 by, for example, the anchor bolt described above. The base and the pillars 51 to 59 are coupled by, for example, a fastener.

  Hereinafter, the pillars 51 to 53 of the first pillar group 41 will be described. The first pillar 51 is disposed on the upper surface of the first protruding corner 31 that is the intersection position of the first upper surface 21A and the second upper surface 22A. The second column 52 is disposed on the first upper surface 21 </ b> A so as to be separated from the first column 51. The separation distance D1 between the first column 51 and the second column 52 is a width W2 of the second beam 62 so that the second beam 62 can be sandwiched between the first column 51 and the second column 52. Is 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 is 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. Is the same. As will be 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 D <b> 1 is ensured by the first spacer 71 inserted between the first pillar 51 and the second pillar 52. Specifically, the first spacer 71 has a rectangular column shape shorter than the first column 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 first pillar 51 and the second pillar are disposed by the fifth fastener 85. 52 is attached.

The beams 61 and 62, the pillars 51 to 57, and the foundation 20 configured in this manner constitute the frame structure 11.

[Function and effect]
In the present embodiment, the first pillar 51, the fourth pillar 54, and the sixth pillar 56 are disposed at the protruding corner portions 31, 32, and 33, respectively. The second column 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 column 57 is disposed on the fourth upper surface 24A. Therefore, the ramen structure 11 can be comprised using the conventional foundation 20 which has the upper surfaces 21A-24A of constant width. That is, the ramen structure 11 can be configured without using a foundation having a configuration different from the conventional configuration such as increasing the protruding corner portions 31 to 33. Further, 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 does not become thick. Further, since the beams 61 and 62 and the columns 51 to 57 are directly fastened, members such as end members are unnecessary.

  In the present embodiment, the spacers 71 to 74 keep the separation distance between the columns 51 to 57 constant in the vertical direction 15. As a result, the construction of the housing 10 can be facilitated. Further, the strength of the rigid frame structure 11 is increased by the spacers 71 to 74.

  In the present embodiment, since the first beam 61 and the second beam 62 are joined by the phase gaps 61A and 62A, the first beam 61 and the second beam 62 can have the same height. And the intensity | strength of the ramen structure 11 can be raised.

  In the present embodiment, a fabric foundation is used for the foundation 20. In a ramen structure, the load concentrates on the pillar. By using the cloth foundation, the columns 51 to 57 on which the load is concentrated can be reliably supported.

[Modification]

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

  The wooden bi-directional frame structure 16 includes a foundation 27, column groups 41 to 43, beams 61 and 62, and a wooden eighth column 60.

  The foundation 27 is different from the foundation 20 in that the foundation 27 is provided. The overhanging portion 28 is provided at a position immediately below the intermediate position in the longitudinal direction of the second beam 62 (second direction 14). The projecting portion 28 has an upper surface 28A that projects from the second upper surface 22A of the second base portion 22 in the width direction. 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 metal fitting described in the above-described embodiment. The eighth column 60 is placed and fixed on the column base metal fitting.

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

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

  In the above-described embodiment, an example in which the foundation 20 is a cloth foundation has been described, but the foundation 20 may be a solid foundation.

  In the above-described embodiment, the example in which the casing 10 is configured only by the ramen structure 11 has been described. However, the housing 10 may be configured by combining the ramen structure 11 and other structures. For example, the other end (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-described embodiment, the 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. When the first upper surface 21 </ b> A and the second upper surface 22 </ b> A intersect at an acute angle or an obtuse angle, for example, the joints between the columns 51 to 57 and the beams 61 and 62 are chamfered according to the side surfaces of the beams 61 and 62.

  In the above-described embodiment, the example in which the first beam 61 and the second beam 62 are joined by the phase gaps 61A and 62A has been described. However, the first beam 61 and the second beam 62 may be joined by tenoning (tenon joint) or butt (butting). In the case of being joined by abutment, the first beam 61 and the second beam 62 are fastened to each other using the above-described reinforcing plate 93 or the like.
