Description

Building

[0001] This disclosure relates to a building.

[0002] Columns composed of a plurality of column components are known. In Patent Document 1, the plurality of column components are arranged in two directions orthogonal to each other in plan view.

[0003] Japanese Patent Application Laid-Open No. 2005-36456

[0004] Improvement in the productivity of columns composed of a plurality of column components is desired.

[0005] (1) A building which is one aspect of the present disclosure includes a wooden column and a column connection target member to which the wooden column is connected. The wooden column is a building composed of a plurality of column components. In the horizontal direction, when the direction in which the column connection target member extends is defined as the first direction and the direction orthogonal to the first direction is defined as the second direction, the cross-sectional shape of the column component is a quadrangular shape, the cross-sectional shape of the wooden column is a quadrangular shape, and the plurality of column components are arranged in a row in the first direction.

[0006] According to this configuration, since the wooden column is composed of a plurality of column components arranged in a row, compared with the case where the wooden column is composed of a plurality of column components arranged in two orthogonal directions, the arrangement work of the column components and the connection work between the column components are easy. Therefore, the productivity of the wooden column can be improved.

[0007] Further, since the plurality of column components are arranged in a row in the first direction, compared with the case where the plurality of column components are arranged in a row in the second direction, it is less likely that the wooden column protrudes in the second direction from the side surface of the column connection target member.

[0008] (2) In the building of (1) above, the cross-sectional shape of the column component is a rectangular shape. When the cross-sectional shape of the column component is a square shape, the cross-sectional shape of the wooden column is limited to a rectangular shape. According to the above configuration, the cross-sectional shape of the wooden column can be a rectangular shape or a square shape.

[0009] (3) In the building described in (1) or (2) above, the cross-sectional shape of the wooden column is rectangular, the longitudinal direction of the wooden column in a plan view is parallel to the first direction, and the short direction of the wooden column in a plan view is parallel to the second direction.

[0010] With this configuration, since the longitudinal direction of the wooden column is parallel to the first direction, compared to a wooden column with the same cross-sectional shape where the longitudinal direction of the wooden column is parallel to the second direction, the wooden column in the above configuration is less likely to protrude from the side of the member to which the column is connected in the second direction.

[0011] (4) In the building described in (3) above, the cross-sectional shape of the column component is rectangular, the longitudinal direction of the column component in plan view is parallel to the second direction, and the short direction of the column component in plan view is parallel to the first direction.

[0012] With this configuration, the ratio of the longitudinal dimension of the wooden column to the transverse dimension of the wooden column becomes smaller compared to the case where the longitudinal direction of the column component is parallel to the first direction and the transverse direction of the column component is parallel to the second direction. Therefore, the strength of the wooden column can be increased.

[0013] (5) In any one of the buildings described in (1) to (4) above, the multiple column components are connected to one another by column connecting members that penetrate the multiple column components in the first direction.

[0014] This configuration allows multiple column components to be connected without bonding adjacent column components in the first direction, resulting in good workability. (6) In any one of the buildings described in (1) to (5) above, a connecting fitting is provided to connect the wooden column and the column connection target member, each of the multiple column components is provided with a slit, the connecting fitting has an insertion plate that is inserted into the slit, and the wooden column is connected to the connecting fitting by a metal connecting member that penetrates the multiple column components and the insertion plate in the first direction.

[0015] This configuration allows a single connecting fitting to connect multiple column components. Furthermore, it prevents deformation of each column component that would cause the width of the slit in the first direction to widen due to a load applied to the wooden column from above.

[0016] (7) In the building described in (6) above, multiple slits are provided in the column component. This configuration makes it possible to increase the connection strength between each column component and the connecting hardware.

[0017] (8) In the building described in (7) above, the wooden column has a plurality of column components, namely a first column component and a second column component, the first column component is provided with a plurality of slits, namely a first slit and a second slit, the second column component is provided with a plurality of slits, namely a third slit and a fourth slit, the connecting hardware has a plurality of insertion plates, namely a first insertion plate inserted into the first slit, a second insertion plate inserted into the second slit, a third insertion plate inserted into the third slit, and a fourth insertion plate inserted into the fourth slit, the second insertion plate is located between the first insertion plate and the fourth insertion plate, the distance between the first insertion plate and the second insertion plate is the same as the distance between the third insertion plate and the fourth insertion plate, and the distance between the second insertion plate and the third insertion plate is greater than the distance between the first insertion plate and the second insertion plate.

[0018] This configuration allows for the suitability of connecting multiple column components and connecting hardware. (9) In any one of the buildings described in (6) to (8) above, the connecting hardware has a first connecting portion connected to the column component to be connected, a support plate and a plurality of insertion plates extending from the support plate, to which the wooden column is connected, and a connecting portion connecting the first connecting portion and the second connecting portion, the connecting portion having two first components spaced apart in the second direction and two second components spaced apart in the first direction, the first component having a first base extending in the first direction and two first extensions extending from the first base away from the other first component, and the second component having a second base extending in the second direction and two second extensions extending from the second base away from the other second component.

[0019] This configuration makes it possible to suppress deformation of the connection point due to loads applied to the connecting hardware from above.

[0020] According to the building described in this disclosure, the productivity of wooden columns can be improved.

[0021] This is a perspective view of the building. This is a cross-sectional view of the building along line 2-2 in Figure 1. This is a front view showing the lower part of the wooden column, the connecting hardware, and part of the foundation. This is a perspective view of the connecting hardware. This is a cross-sectional view of the connecting hardware along line 5-5 in Figure 3.

[0022] The building 10 of this embodiment will be described with reference to Figures 1 to 5. The building 10 is a medium-to-large-scale building. The following description will focus on the first floor of the building 10. In some countries, such as the United Kingdom and Australia, "first floor" and "second floor" in this specification may be read as "ground floor" and "first floor" respectively.

[0023] As shown in Figure 1, the building 10 comprises a foundation 11, wooden columns 12, and connecting hardware 13. The foundation 11 has a reinforced concrete foundation 11a. Anchor bolts 14a are embedded in the foundation 11a (see Figure 3). The anchor bolts 14a protrude from the upper surface of the foundation 11a. The wooden columns 12 are provided on top of the foundation 11. The connecting hardware 13 is positioned between the foundation 11 and the wooden columns 12. The connecting hardware 13 connects the foundation 11 and the wooden columns 12. Therefore, in this embodiment, the foundation 11 is a column connection target member to which the wooden columns 12 are connected via the connecting hardware 13.

[0024] In the horizontal direction, the direction in which the foundation 11, which is the member to be connected to the column, extends is defined as the first direction X1, and the direction perpendicular to the first direction X1 is defined as the second direction X2. In the second direction X2, the space on one side of the foundation 11 is outdoors, and the space on the other side of the foundation 11 is indoors.

[0025] <Wooden Column> As shown in Figure 2, the cross-sectional shape of the wooden column 12 is rectangular. In this embodiment, the cross-sectional shape of the wooden column 12 is rectangular. Note that in Figure 2, the cross-sectional hatching of the wooden column 12 is omitted. In plan view, the longitudinal direction of the wooden column 12 is parallel to the first direction X1. In plan view, the short direction of the wooden column 12 is parallel to the second direction X2.

[0026] The wooden column 12 has a first side surface 12a, a second side surface 12b, a third side surface 12c, and a fourth side surface 12d. The first side surface 12a and the second side surface 12b are paired in the first direction X1. The third side surface 12c and the fourth side surface 12d are paired in the second direction X2.

[0027] The wooden column 12 in this embodiment is composed of two column components 20. The two column components 20 are identical in shape. When distinguishing between the two column components 20, one column component 20 is referred to as the first column component 20a, and the other column component 20 is referred to as the second column component 20b.

[0028] The cross-sectional shape of each column component 20 is rectangular. In this embodiment, the cross-sectional shape of each column component 20 is rectangular. In this embodiment, the longitudinal dimension of the column component 20 in a plan view is greater than 1 times the transverse dimension of the column component 20 in a plan view, and less than 2 times the transverse dimension of the column component 20 in a plan view. The two column components 20 are arranged in a line in the first direction X1. In this embodiment, the longitudinal direction of each column component 20 in a plan view is parallel to the second direction X2. The transverse direction of each column component 20 in a plan view is parallel to the first direction X1.

[0029] Each column component 20 has a first side surface 201, a second side surface 202, a third side surface 203, and a fourth side surface 204. The first side surface 201 and the second side surface 202 are paired in a first direction X1. The third side surface 203 and the fourth side surface 204 are paired in a second direction X2. The second side surface 202 of the first column component 20a is in contact with the first side surface 201 of the second column component 20b.

[0030] The first side surface 12a of the wooden column 12 is formed by the first side surface 201 of the first column component 20a. The second side surface 12b of the wooden column 12 is formed by the second side surface 202 of the second column component 20b. The third side surface 12c of the wooden column 12 is formed by the third side surface 203 of the first column component 20a and the third side surface 203 of the second column component 20b. The fourth side surface 12d of the wooden column 12 is formed by the fourth side surface 204 of the first column component 20a and the fourth side surface 204 of the second column component 20b.

[0031] As shown in Figure 1, each column component 20 has three upper connecting holes 21 at its upper part. Each upper connecting hole 21 penetrates the column component 20 in a first direction X1. Each column component 20 has one lower connecting hole 22 at its lower part. Each lower connecting hole 22 penetrates the column component 20 in a first direction X1. Each column component 20 has seven metal fitting connecting holes 23 at its lower part. Each metal fitting connecting hole 23 penetrates the column component 20 in a first direction X1. Each column component 20 has three central connecting holes 24 in its central part in the vertical direction. Each central connecting hole 24 penetrates the column component 20 in a first direction X1.

[0032] Upper connecting bolts 15, which serve as column connecting members, are inserted through the upper connecting holes 21 of the first column component 20a and the upper connecting holes 21 of the second column component 20b. Upper connecting nuts (not shown) are locked onto the upper connecting bolts 15. As a result, the upper parts of the first column component 20a and the second column component 20b are connected to each other.

[0033] As shown in Figure 2, a lower connecting bolt 16a, which serves as a column connecting member, is inserted through the lower connecting hole 22 of the first column component 20a and the lower connecting hole 22 of the second column component 20b. A lower connecting nut 16b is locked onto the lower connecting bolt 16a. As a result, the lower parts of the first column component 20a and the second column component 20b are connected to each other.

[0034] As shown in Figure 1, a central connecting bolt 17, which serves as a column connecting member, is inserted through the central connecting hole 24 of the first column component 20a and the central connecting hole 24 of the second column component 20b. A central connecting nut (not shown) is locked onto the central connecting bolt 17. As a result, the central portion of the first column component 20a and the central portion of the second column component 20b in the vertical direction are connected to each other. In this way, the first column component 20a and the second column component 20b are connected to each other by bolts and nuts without the use of adhesive.

[0035] As shown in Figure 3, each column component 20 has a slit 25 on its lower surface into which an insertion plate 35, described later, is inserted. In this embodiment, each column component 20 has two slits 25 on its lower surface. The two slits 25 on each column component 20 are spaced apart in the first direction X1.

[0036] Of the two slits 25 provided in the first column component 20a, one slit 25 is called the first slit 25a and the other slit 25 is called the second slit 25b. The first slit 25a is located closer to the first side surface 201 of the first column component 20a than the second slit 25b. Of the two slits 25 provided in the second column component 20b, one slit 25 is called the third slit 25c and the other slit 25 is called the fourth slit 25d. The third slit 25c is located closer to the first side surface 201 of the second column component 20b than the fourth slit 25d.

[0037] In this embodiment, the distance from the first side surface 201 of the first column component 20a to the first slit 25a, the distance from the first slit 25a to the second slit 25b, and the distance from the second slit 25b to the second side surface 202 of the first column component 20a are the same. The distance from the first side surface 201 of the second column component 20b to the third slit 25c, the distance from the third slit 25c to the fourth slit 25d, and the distance from the fourth slit 25d to the second side surface 202 of the second column component 20b are the same. In this embodiment, each slit 25 is open on the third side surface 203 and the fourth side surface 204 of the column component 20.

[0038] <Connecting Hardware> As shown in Figures 3 and 4, the connecting hardware 13 has a first connecting portion 31 connected to the column to be connected member, a second connecting portion 32 to which the wooden column 12 is connected, and a connecting portion 33 that connects the first connecting portion 31 and the second connecting portion 32. In this embodiment, the first connecting portion 31 is connected to the foundation portion 11.

[0039] The first connecting portion 31 is made up of a rectangular plate. The first connecting portion 31 is provided with a plurality of first connecting holes 31a. The first connecting holes 31a penetrate the first connecting portion 31 in the thickness direction.

[0040] An anchor bolt 14a is inserted into a first connection hole 31a of the first connection part 31. A nut 14b is locked to the anchor bolt 14a. Thus, the first connection part 31 of the connecting metal fitting 13 is connected to the base part 11.

[0041] The second connection part 32 has a rectangular support plate 34 and four insertion plates 35 extending from the upper surface of the support plate 34. When distinguishing the four insertion plates 35, they are referred to as a first insertion plate 35a, a second insertion plate 35b, a third insertion plate 35c, and a fourth insertion plate 35d.

[0042] The four insertion plates 35 are arranged at intervals in the order of the first insertion plate 35a, the second insertion plate 35b, the third insertion plate 35c, and the fourth insertion plate 35d in the first direction X1. The second insertion plate 35b is located between the first insertion plate 35a and the fourth insertion plate 35d. The third insertion plate 35c is located between the second insertion plate 35b and the fourth insertion plate 35d. The interval between the first insertion plate 35a and the second insertion plate 35b is the same as the interval between the third insertion plate 35c and the fourth insertion plate 35d. The interval between the second insertion plate 35b and the third insertion plate 35c is larger than the interval between the first insertion plate 35a and the second insertion plate 35b. The plate thickness direction of each insertion plate 35 is parallel to the direction in which the four insertion plates 35 are arranged.

[0043] Each insertion plate 35 is provided with one bolt insertion hole 36 and seven second connection holes 37. The bolt insertion hole 36 and the seven second connection holes 37 penetrate each insertion plate 35 in the plate thickness direction.

[0044] As shown in FIG. 5, the connection part 33 of the present embodiment is composed of two first components 41 and two second components 42. The two first components 41 and the two second components 42 are fixed to the support plate 34 of the first connection part 31 and the second connection part 32 by welding, respectively.

[0045] The two first components 41 are arranged at intervals in the second direction X2. The first component 41 has a first base 41a extending in the first direction X1 and two first extension parts 41b extending in a direction away from the other first component 41 from the first base 41a.

[0046] The two second components 42 are arranged at intervals in the first direction X1. The second component 42 has a second base 42a extending in the second direction X2 and two second extension parts 42b extending in a direction away from the other second component 42 from the second base 42a.

[0047] As shown in FIG. 3, the first insertion plate 35a is inserted into the first slit 25a of the first column component member 20a. The second insertion plate 35b is inserted into the second slit 25b of the first column component member 20a. The third insertion plate 35c is inserted into the third slit 25c of the second column component member 20b. The fourth insertion plate 35d is inserted into the fourth slit 25d of the second column component member 20b.

[0048] In addition to the lower connection holes 22 of the first column component member 20a and the lower connection holes 22 of the second column component member 20b, the above-described lower connection bolt 16a is also inserted into the bolt insertion holes 36 of each insertion plate 35. That is, the lower connection bolt 16a penetrates the first column component member 20a, each insertion plate 35, and the second column component member 20b in the first direction X1.

[0049] A drift pin 18 as a metal connection member is inserted into the metal connection hole 23 of the first column component member 20a, the second connection hole 37 of each insertion plate 35, and the metal connection hole 23 of the second column component member 20b. That is, the drift pin 18 penetrates the first column component member 20a, each insertion plate 35, and the second column component member 20b in the first direction X1. Thereby, the first column component member 20a and the second column component member 20b are connected to the second connection portion 32 of the connecting metal fitting 13. Therefore, the wooden column 12 is connected to the second connection portion 32 of the connecting metal fitting 13.

[0050] [Operation of this Embodiment] The operation of this embodiment will now be explained. The wooden column 12 is composed of two column components 20. Therefore, compared to the case where the wooden column 12 is composed of a single piece of wood, the wooden column 12 is less likely to buckle. Consequently, the length of the wooden column 12 can be increased, and the height of the ceiling on the first floor can be increased.

[0051] Furthermore, the wooden column 12 is composed of column components 20 arranged in a single row. Therefore, compared to the case where the wooden column is composed of column components arranged in two orthogonal directions, the work of arranging the column components 20 and connecting the column components 20 to each other is easier. Thus, the productivity of the wooden column 12 can be improved.

[0052] Furthermore, the two column components 20 are arranged in a line in the first direction X1. Therefore, compared to the case where the two column components 20 are arranged in a line in the second direction X2, the wooden column 12 is less likely to protrude from the side of the foundation 11 in the second direction X2. As the wooden column 12 is less likely to protrude into the indoor space beyond the foundation 11, the freedom of furniture arrangement indoors is increased and the aesthetic design of the interior is improved. As the wooden column 12 is less likely to protrude into the outdoor space beyond the foundation 11, the aesthetic design of the building 10's exterior is improved.

[0053] [Effects of this embodiment] The effects of this embodiment will be explained. (1) The wooden column 12 is composed of column components 20 arranged in a row in the first direction X1. This makes the arrangement of the column components 20 and the connection of the column components 20 easier compared to the case in which the wooden column is composed of column components arranged in two orthogonal directions. Therefore, the productivity of the wooden column 12 can be improved. Also, compared to the case in which the column components 20 are arranged in the second direction X2, the wooden column 12 is less likely to protrude from the side of the foundation 11 in the second direction X2.

[0054] (2) If the cross-sectional shape of the column component 20 is square, the cross-sectional shape of the wooden column 12 is limited to a rectangular shape. In contrast, since the cross-sectional shape of the column component 20 in this embodiment is rectangular, the cross-sectional shape of the wooden column 12 can be rectangular or square.

[0055] (3) The cross-sectional shape of the wooden column 12 is rectangular. In a plan view, the longitudinal direction of the wooden column 12 is parallel to the first direction X1. In a plan view, the short direction of the wooden column 12 is parallel to the second direction X2. As a result, compared to a wooden column with the same cross-sectional shape where the longitudinal direction of the wooden column is parallel to the second direction X2, the wooden column 12 of this embodiment is less likely to protrude from the side of the foundation 11 in the second direction X2.

[0056] (4) In a plan view, the longitudinal direction of the column component 20 is parallel to the second direction X2. In a plan view, the short direction of the column component 20 is parallel to the first direction X1. As a result, compared to the case where the longitudinal direction of the column component 20 is parallel to the first direction X1 and the short direction of the column component 20 is parallel to the second direction X2, the ratio of the longitudinal dimension of the wooden column 12 to the short dimension of the wooden column 12 becomes smaller. Therefore, the strength of the wooden column 12 can be increased.

[0057] (5) The two column components 20 are connected to each other by an upper connecting bolt 15, a lower connecting bolt 16a, and a central connecting bolt 17, which penetrate the two column components 20 in the first direction X1. With this configuration, the two column components 20 can be connected without bonding adjacent column components 20 in the first direction X1, resulting in good workability.

[0058] (6) The building 10 is equipped with connecting hardware 13 that connects the foundation 11 and the wooden column 12. Slits 25 are provided on the lower surfaces of each of the two column components 20. The connecting hardware 13 has an insertion plate 35 that is inserted into the slits 25. The wooden column 12 is connected to the connecting hardware 13 by drift pins 18 that penetrate the multiple column components 20 and the insertion plate 35 in the first direction X1.

[0059] This configuration allows one connecting fitting 13 to be connected to two column components 20. Furthermore, it prevents deformation of each column component 20 so that the width of the slit 25 in the first direction X1 widens due to the load applied to the wooden column 12 from above.

[0060] (7) Two slits 25 are provided in each column component 20. This configuration increases the connection strength between each column component 20 and the connecting hardware 13. (8) The wooden column 12 has a first column component 20a and a second column component 20b. The first column component 20a is provided with a first slit 25a and a second slit 25b. The second column component 20b is provided with a third slit 25c and a fourth slit 25d. The connecting hardware 13 has a first insertion plate 35a inserted into the first slit 25a, a second insertion plate 35b inserted into the second slit 25b, a third insertion plate 35c inserted into the third slit 25c, and a fourth insertion plate 35d inserted into the fourth slit 25d.

[0061] The second insertion plate 35b is located between the first insertion plate 35a and the fourth insertion plate 35d. The third insertion plate 35c is located between the second insertion plate 35b and the fourth insertion plate 35d. The distance between the first insertion plate 35a and the second insertion plate 35b is the same as the distance between the third insertion plate 35c and the fourth insertion plate 35d. The distance between the second insertion plate 35b and the third insertion plate 35c is greater than the distance between the first insertion plate 35a and the second insertion plate 35b.

[0062] This configuration allows for a suitable connection between the two column components 20 and the connecting hardware 13. (9) The connecting hardware 13 has a first connecting portion 31, a second connecting portion 32, and a connecting portion 33. The first connecting portion 31 is connected to the foundation portion 11. The second connecting portion 32 has a support plate 34 and a plurality of insertion plates 35 extending from the support plate 34. The wooden column 12 is connected to the second connecting portion 32. The connecting portion 33 connects the first connecting portion 31 and the second connecting portion 32.

[0063] The connecting portion 33 has two first components 41 and two second components 42. The first components 41 are spaced apart in the second direction X2. The second components 42 are spaced apart in the first direction X1. The first component 41 has a first base 41a and two first extensions 41b. The first base 41a extends in the first direction X1. The two first extensions 41b extend away from the first base 41a in a direction away from the other first component 41. The second component 42 has a second base 42a and two second extensions 42b. The second base 42a extends in the second direction X2. The two second extensions 42b extend away from the second base 42a in a direction away from the other second component 42.

[0064] With this configuration, deformation of the connecting part 33 due to the load applied to the connecting hardware 13 from above can be suppressed. (10) The wooden column 12 is made up of two column components 20. Therefore, compared to the case where the wooden column 12 is made up of a single piece of wood, the wooden column 12 is less likely to buckle. As a result, the length of the wooden column 12 can be increased, and the height of the ceiling on the first floor can be increased.

[0065] (11) Since the two column components 20 are integrated by being connected with bolts and nuts, the same strength of the wooden column 12 can be obtained as if the two column components 20 were bonded to each other with adhesive.

[0066] (12) Although not shown, the building 10 may have horizontal members extending in the second direction X2. In this embodiment, the cross-sectional shape of the wooden column 12 is rectangular, and the longitudinal direction of the wooden column 12 in plan view is parallel to the first direction X1. Therefore, even if the dimension of the horizontal member in the first direction X1 is large, the horizontal member can be connected to the side of the wooden column 12. When the dimension of the horizontal member in the first direction X1 is large, the length of the horizontal member can be increased, making it easier to realize a large space.

[0067] (13) The first column component 20a and the second column component 20b are connected to each other at three locations: the upper part, the middle part, and the lower part. With this configuration, the connection strength of the first column component 20a and the second column component 20b can be increased compared to the case in which the first column component 20a and the second column component 20b are connected to each other at two locations: the upper part and the lower part.

[0068] (14) The wooden column 12 is composed of two column components 20 arranged in a line in the first direction X1. As a result, compared to the case in which the wooden column is composed of column components arranged in two orthogonal directions, the manufacturing cost of the wooden column 12 can be reduced because the number of column components 20 is smaller. Therefore, the manufacturing cost of the building 10 can be reduced.

[0069] <Examples of Modifications> The above embodiment is an example of the forms that the building 10 may take, and is not intended to limit its form. The building 10 may take a form different from the form exemplified in the above embodiment.
