Description

[Technical Field]

[0001] The present disclosure relates to buildings. [Background technology]

[0002] A pillar constituted by a plurality of pillar-constituting members is known. In Patent Document 1, the plurality of pillar-constituting members are arranged in two directions perpendicular to each other in a plan view. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-36456 Summary of the Invention [Problem to be solved by the invention]

[0004] There is a demand for improved productivity in producing columns made up of multiple column-constituting members. [Means for solving the problem]

[0005] (1) A building that solves the above problem comprises a wooden pillar and a pillar connection target member to which the wooden pillar is connected, the wooden pillar being a building composed of a plurality of pillar constituent members, and when the horizontal direction in which the pillar connection target member extends is defined as a first direction and a direction perpendicular to the first direction is defined as a second direction, the cross-sectional shape of the pillar constituent member is rectangular, the cross-sectional shape of the wooden pillar is rectangular, and the plurality of pillar constituent members are arranged in a row in the first direction.

[0006] With this configuration, the wooden post is made up of multiple post-constituting members arranged in a row, which makes it easier to arrange and connect the post-constituting members than when a wooden post is made up of multiple post-constituting members arranged in two perpendicular directions, thereby improving the productivity of wooden posts.

[0007] Furthermore, since the multiple pillar components are arranged in a row in the first direction, the wooden pillar is less likely to protrude in the second direction from the side of the pillar connection target component compared to when the multiple pillar components are arranged in a row in the second direction.

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

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

[0010] According to this configuration, the longitudinal direction of the wooden post is parallel to the first direction, so compared to a wooden post of the same cross-sectional shape in which the longitudinal direction of the wooden post is parallel to the second direction, the wooden post of the above configuration is less likely to protrude from the side of the post connection target component in the second direction.

[0011] (4) In the building of (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 pillar to the lateral dimension of the wooden pillar is smaller than when the longitudinal direction of the pillar component is parallel to the first direction and the lateral direction of the pillar component is parallel to the second direction, thereby increasing the strength of the wooden pillar.

[0013] (5) In the building of any one of (1) to (4) above, the plurality of column constituent members are connected to one another by a column connecting member that penetrates the plurality of column constituent members in the first direction. According to this configuration, multiple pillar components can be connected without bonding adjacent pillar components in the first direction, which improves workability.

[0014] (6) In any one of the buildings (1) to (5) above, a connecting hardware is provided to connect the wooden column and the column connection handling member, each of the plurality of column constituent members is provided with a slit, the connecting hardware has an insertion plate inserted into the slit, and the wooden column is connected to the connecting hardware in the first direction by a hardware connecting member that penetrates the plurality of column constituent members and the insertion plate.

[0015] This configuration allows one connecting metal fitting to connect multiple pillar components, and also prevents the pillar components from deforming in a way that widens the width of the slit in the first direction due to a load applied to the wooden pillar from above.

[0016] (7) In the building of (6) above, the slits are provided in a plurality of the column components. This configuration increases the connection strength between each column component and the connecting hardware.

[0017] (8) In the building of (7) above, the wooden column has a first column component and a second column component as the plurality of column components, the first column component has a first slit and a second slit as the plurality of slits, the second column component has a third slit and a fourth slit as the plurality of slits, the connecting hardware has a plurality of insert plates, a first insert plate inserted into the first slit, a second insert plate inserted into the second slit, a third insert plate inserted into the third slit, and a fourth insert plate inserted into the fourth slit, the second insert plate is located between the first insert plate and the fourth insert plate, the third insert plate is located between the second insert plate and the fourth insert plate, the distance between the first insert plate and the second insert plate is the same as the distance between the third insert plate and the fourth insert plate, and the distance between the second insert plate and the third insert plate is larger than the distance between the first insert plate and the second insert plate. This configuration allows multiple column components and connecting hardware to be connected in an appropriate manner.

[0018] (9) In any one of the buildings (6) to (8) above, the connecting hardware has a first connecting portion connected to the column connection target component, a support plate, and a plurality of the insertion plates extending from the support plate, a second connecting portion 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 constituent portions arranged at intervals in the second direction and two second constituent portions arranged at intervals in the first direction, the first constituent portion having a first base portion extending in the first direction and two first extension portions extending from the first base portion in a direction away from the other first constituent portion, and the second constituent portion having a second base portion extending in the second direction and two second extension portions extending from the second base portion in a direction away from the other second constituent portion.

[0019] This configuration can prevent the connection portion from being deformed by a load applied to the connecting hardware from above. [Effects of the Invention]

[0020] The building of the present disclosure can improve the productivity of wooden poles. [Brief explanation of the drawings]

[Figure 3] A front view showing the lower part of the wooden pillar, the connecting hardware, and part of the foundation. [Figure 4] FIG. [Figure 5] 5 is a cross-sectional view of the connector taken along line 5-5 in FIG. 3. DETAILED DESCRIPTION OF THE INVENTION

[0022] A 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. In the following description, the first floor of the building 10 will be described. As shown in FIG. 1, a building 10 includes a foundation 11, a wooden column 12, and a connecting hardware 13. The foundation 11 has a reinforced concrete foundation 11a. An anchor bolt 14a is embedded in the foundation 11a (see FIG. 3). The anchor bolt 14a protrudes from the top surface of the foundation 11a. The wooden column 12 is provided on the foundation 11. The connecting hardware 13 is disposed between the foundation 11 and the wooden column 12. The connecting hardware 13 connects the foundation 11 and the wooden column 12. Therefore, the foundation 11 in this embodiment is a column connection target member to which the wooden column 12 is connected via the connecting hardware 13.

[0023] Among the horizontal directions, the direction in which the foundation part 11, which is the column connection target member, 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 part 11 is outdoors, and the space on the other side of the foundation part 11 is indoors.

[0024] <Wooden pillar> As shown in Fig. 2, the cross-sectional shape of the wooden post 12 is quadrangular. In this embodiment, the cross-sectional shape of the wooden post 12 is rectangular. Note that hatching of the cross section of the wooden post 12 is omitted in Fig. 2. The longitudinal direction of the wooden post 12 in plan view is parallel to the first direction X1. The lateral direction of the wooden post 12 in plan view is parallel to the second direction X2.

[0025] The wooden post 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 form a pair in the first direction X1. The third side surface 12c and the fourth side surface 12d form a pair in the second direction X2.

[0026] The wooden post 12 of this embodiment is composed of two post components 20. The two post components 20 have the same shape. When distinguishing between the two post components 20, one post component 20 is referred to as the first post component 20a, and the other post component 20 is referred to as the second post component 20b.

[0027] The cross-sectional shape of each pillar component 20 is quadrangular. In this embodiment, the cross-sectional shape of each pillar component 20 is rectangular. In this embodiment, the longitudinal dimension of each pillar component 20 in plan view is greater than one time the lateral dimension of the pillar component 20 in plan view and less than two times the lateral dimension of the pillar component 20 in plan view. Two pillar components 20 are arranged in a row in the first direction X1. In this embodiment, the longitudinal direction of each pillar component 20 in plan view is parallel to the second direction X2. The lateral direction of each pillar component 20 in plan view is parallel to the first direction X1.

[0028] Each pillar 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 form a pair in the first direction X1. The third side surface 203 and the fourth side surface 204 form a pair in the second direction X2. The second side surface 202 of the first pillar component 20a is in contact with the first side surface 201 of the second pillar component 20b.

[0029] The first side surface 12a of the wooden post 12 is formed by the first side surface 201 of the first post component 20a. The second side surface 12b of the wooden post 12 is formed by the second side surface 202 of the second post component 20b. The third side surface 12c of the wooden post 12 is formed by the third side surface 203 of the first post component 20a and the third side surface 203 of the second post component 20b. The fourth side surface 12d of the wooden post 12 is formed by the fourth side surface 204 of the first post component 20a and the fourth side surface 204 of the second post component 20b.

[0030] As shown in FIG. 1 , three upper connecting holes 21 are provided in the upper part of each pillar component 20. Each upper connecting hole 21 penetrates the pillar component 20 in the first direction X1. One lower connecting hole 22 is provided in the lower part of each pillar component 20. Each lower connecting hole 22 penetrates the pillar component 20 in the first direction X1. Seven metal connecting holes 23 are provided in the lower part of each pillar component 20. Each metal connecting hole 23 penetrates the pillar component 20 in the first direction X1. Three central connecting holes 24 are provided in the central part of each pillar component 20 in the up-down direction. Each central connecting hole 24 penetrates the pillar component 20 in the first direction X1.

[0031] An upper connecting bolt 15 serving as a pillar connecting member is inserted into the upper connecting hole 21 of the first pillar component 20a and the upper connecting hole 21 of the second pillar component 20b. An upper connecting nut (not shown) is engaged with the upper connecting bolt 15. This connects the upper part of the first pillar component 20a and the upper part of the second pillar component 20b to each other.

[0032] As shown in Figure 2, a lower connecting bolt 16a serving as a pillar connecting member is inserted into the lower connecting hole 22 of the first pillar component 20a and the lower connecting hole 22 of the second pillar component 20b. A lower connecting nut 16b is engaged with the lower connecting bolt 16a. This connects the lower part of the first pillar component 20a and the lower part of the second pillar component 20b to each other.

[0033] As shown in Figure 1, a central connecting bolt 17 serving as a pillar connecting member is inserted into the central connecting hole 24 of the first pillar component 20a and the central connecting hole 24 of the second pillar component 20b. A central connecting nut (not shown) is engaged with the central connecting bolt 17. This connects the vertical central portion of the first pillar component 20a and the vertical central portion of the second pillar component 20b to each other. In this way, the first pillar component 20a and the second pillar component 20b are connected to each other with bolts and nuts without using adhesive.

[0034] 3, a slit 25 into which an insertion plate 35 (described later) is inserted is provided on the lower surface of each pillar component 20. In this embodiment, two slits 25 are provided on the lower surface of each pillar component 20. The two slits 25 provided in each pillar component 20 are aligned with an interval in the first direction X1.

[0035] Of the two slits 25 provided in the first pillar component 20a, one slit 25 is referred to as the first slit 25a, and the other slit 25 is referred to as the second slit 25b. The first slit 25a is located closer to the first side surface 201 of the first pillar component 20a than the second slit 25b. Of the two slits 25 provided in the second pillar component 20b, one slit 25 is referred to as the third slit 25c, and the other slit 25 is referred to as the fourth slit 25d. The third slit 25c is located closer to the first side surface 201 of the second pillar component 20b than the fourth slit 25d.

[0036] In this embodiment, the distance from the first side surface 201 of the first pillar 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 pillar component 20a are the same. The distance from the first side surface 201 of the second pillar 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 pillar component 20b are the same. In this embodiment, each slit 25 opens on the third side surface 203 and the fourth side surface 204 of the pillar component 20.

[0037] <Connecting hardware> 3 and 4, the connecting hardware 13 has a first connecting portion 31 connected to the column connection target 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 base portion 11.

[0038] The first connecting portion 31 is configured by a rectangular plate. A plurality of first connecting holes 31a are provided in the first connecting portion 31. The first connecting holes 31a penetrate the first connecting portion 31 in the thickness direction.

[0039] An anchor bolt 14a is inserted into the first connecting hole 31a of the first connecting portion 31. A nut 14b is engaged with the anchor bolt 14a. This connects the first connecting portion 31 of the connecting hardware 13 to the base portion 11.

[0040] The second connecting portion 32 has a rectangular support plate 34 and four insert plates 35 extending from the upper surface of the support plate 34. When distinguishing between the four insert plates 35, they are referred to as a first insert plate 35a, a second insert plate 35b, a third insert plate 35c, and a fourth insert plate 35d.

[0041] The four insert plates 35 are arranged in the first direction X1 with a gap between them in the following order: first insert plate 35a, second insert plate 35b, third insert plate 35c, and fourth insert plate 35d. The second insert plate 35b is located between the first insert plate 35a and the fourth insert plate 35d. The third insert plate 35c is located between the second insert plate 35b and the fourth insert plate 35d. The distance between the first insert plate 35a and the second insert plate 35b is the same as the distance between the third insert plate 35c and the fourth insert plate 35d. The distance between the second insert plate 35b and the third insert plate 35c is larger than the distance between the first insert plate 35a and the second insert plate 35b. The thickness direction of each insert plate 35 is parallel to the direction in which the four insert plates 35 are arranged.

[0042] 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 each penetrate each insertion plate 35 in the plate thickness direction.

[0043] 5, the connection portion 33 of this embodiment is composed of two first constituent parts 41 and two second constituent parts 42. The two first constituent parts 41 and the two second constituent parts 42 are fixed to the support plates 34 of the first connecting portion 31 and the second connecting portion 32, respectively, by welding.

[0044] The two first component parts 41 are arranged at an interval in the second direction X2. The first component part 41 has a first base part 41a extending in the first direction X1 and two first extending parts 41b extending from the first base part 41a in a direction away from the other first component part 41.

[0045] The two second component parts 42 are arranged at an interval in the first direction X1. The second component part 42 has a second base part 42a extending in the second direction X2 and two second extending parts 42b extending from the second base part 42a in a direction away from the other second component part 42.

[0046] As shown in Figure 3, the first insertion plate 35a is inserted into the first slit 25a of the first pillar component 20a. The second insertion plate 35b is inserted into the second slit 25b of the first pillar component 20a. The third insertion plate 35c is inserted into the third slit 25c of the second pillar component 20b. The fourth insertion plate 35d is inserted into the fourth slit 25d of the second pillar component 20b.

[0047] The above-mentioned lower connecting bolt 16a is inserted into the lower connecting hole 22 of the first pillar component 20a and the lower connecting hole 22 of the second pillar component 20b, as well as into the bolt insertion hole 36 of each insertion plate 35. In other words, the lower connecting bolt 16a penetrates through the first pillar component 20a, each insertion plate 35, and the second pillar component 20b in the first direction X1.

[0048] A drift pin 18 serving as a metal connecting member is inserted through the metal connecting hole 23 of the first pillar component 20a, the second connecting hole 37 of each insertion plate 35, and the metal connecting hole 23 of the second pillar component 20b. That is, the drift pin 18 penetrates the first pillar component 20a, each insertion plate 35, and the second pillar component 20b in the first direction X1. This connects the first pillar component 20a and the second pillar component 20b to the second connecting portion 32 of the connecting hardware 13. Therefore, the wooden pillar 12 is connected to the second connecting portion 32 of the connecting hardware 13.

[0049] [Operation of this embodiment] The operation of this embodiment will be described. The wooden column 12 is composed of two column components 20. Therefore, the wooden column 12 is less likely to buckle than if it were composed of a single piece of wood. Therefore, the length of the wooden column 12 can be increased, allowing the ceiling height on the first floor to be increased.

[0050] Furthermore, the wooden post 12 is composed of post-constituting members 20 arranged in a row. Therefore, compared to when a wooden post is composed of post-constituting members arranged in two perpendicular directions, the work of arranging the post-constituting members 20 and the work of connecting the post-constituting members 20 to each other are easier. Therefore, the productivity of the wooden post 12 can be improved.

[0051] Furthermore, the two pillar components 20 are arranged in a line in the first direction X1. Therefore, compared to when the two pillar components 20 are arranged in a line in the second direction X2, the wooden pillar 12 is less likely to protrude from the side surface of the foundation 11 in the second direction X2. Since the wooden pillar 12 is less likely to protrude into the space indoors beyond the foundation 11, the degree of freedom in arranging furniture indoors increases and the design of the interior is improved. Since the wooden pillar 12 is less likely to protrude into the space outdoor beyond the foundation 11, the design of the exterior of the building 10 is improved.

[0052] [Effects of this embodiment] The effects of this embodiment will be described. (1) The wooden pillar 12 is composed of pillar components 20 arranged in a row in the first direction X1. This makes it easier to arrange the pillar components 20 and connect the pillar components 20 together than when a wooden pillar is composed of pillar components arranged in two perpendicular directions. This improves the productivity of the wooden pillar 12. Furthermore, compared to when the pillar components 20 are arranged in the second direction X2, the wooden pillar 12 is less likely to protrude from the side of the base portion 11 in the second direction X2.

[0053] (2) When the cross-sectional shape of the column constituent member 20 is square, the cross-sectional shape of the wooden column 12 is limited to rectangular. In contrast, since the cross-sectional shape of the column constituent member 20 of this embodiment is rectangular, the cross-sectional shape of the wooden column 12 can be rectangular or square.

[0054] (3) The cross-sectional shape of the wooden post 12 is rectangular. The longitudinal direction of the wooden post 12 in plan view is parallel to the first direction X1. The lateral direction of the wooden post 12 in plan view is parallel to the second direction X2. As a result, the wooden post 12 of this embodiment is less likely to protrude from the side surface of the base portion 11 in the second direction X2, compared to a wooden post with the same cross-sectional shape but whose longitudinal direction is parallel to the second direction X2.

[0055] (4) In plan view, the longitudinal direction of the column constituent member 20 is parallel to the second direction X2. In plan view, the lateral direction of the column constituent member 20 is parallel to the first direction X1. As a result, the ratio of the longitudinal dimension of the wooden column 12 to the lateral dimension of the wooden column 12 is smaller than when the longitudinal direction of the column constituent member 20 is parallel to the first direction X1 and the lateral direction of the column constituent member 20 is parallel to the second direction X2. Therefore, the strength of the wooden column 12 can be increased.

[0056] (5) The two column constituent members 20 are connected to each other in the first direction X1 by an upper connecting bolt 15, a lower connecting bolt 16a, and a central connecting bolt 17, which penetrate the two column constituent members 20. This configuration allows the two column constituent members 20 to be connected without bonding the column constituent members 20 adjacent to each other in the first direction X1, thereby improving workability.

[0057] (6) The building 10 includes a connecting hardware 13 that connects the foundation 11 and the wooden column 12. A slit 25 is provided on the underside of each of the two column components 20. The connecting hardware 13 has an insertion plate 35 that is inserted into the slit 25. The wooden column 12 is connected to the connecting hardware 13 by a drift pin 18 that passes through the multiple column components 20 and the insertion plate 35 in the first direction X1.

[0058] This configuration allows one connecting hardware 13 to connect two pillar components 20. It also prevents each pillar component 20 from being deformed by a load applied to the wooden pillar 12 from above, which would increase the width of the slit 25 in the first direction X1.

[0059] (7) Two slits 25 are provided in each of the column constituent members 20. With this configuration, the connection strength between each of the column constituent members 20 and the connecting metal fittings 13 can be increased. (8) The wooden post 12 has a first post-constituting member 20a and a second post-constituting member 20b. The first post-constituting member 20a has a first slit 25a and a second slit 25b. The second post-constituting member 20b has 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.

[0060] The second insert plate 35b is located between the first insert plate 35a and the fourth insert plate 35d. The third insert plate 35c is located between the second insert plate 35b and the fourth insert plate 35d. The distance between the first insert plate 35a and the second insert plate 35b is the same as the distance between the third insert plate 35c and the fourth insert plate 35d. The distance between the second insert plate 35b and the third insert plate 35c is greater than the distance between the first insert plate 35a and the second insert plate 35b.

[0061] According to this configuration, the two pillar constituent members 20 and the connecting metal fitting 13 can be suitably connected. (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 base portion 11. The second connecting portion 32 has a support plate 34 and a plurality of insert plates 35 extending from the support plate 34. The wooden post 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.

[0062] The connecting portion 33 has two first constituent portions 41 and two second constituent portions 42. The first constituent portions 41 are arranged at an interval in the second direction X2. The second constituent portions 42 are arranged at an interval in the first direction X1. The first constituent portion 41 has a first base portion 41a and two first extending portions 41b. The first base portion 41a extends in the first direction X1. The two first extending portions 41b extend from the first base portion 41a in a direction away from the other first constituent portion 41. The second constituent portion 42 has a second base portion 42a and two second extending portions 42b. The second base portion 42a extends in the second direction X2. The two second extending portions 42b extend from the second base portion 42a in a direction away from the other second constituent portion 42.

[0063] This configuration can prevent the connection portion 33 from being deformed by a load applied to the connection metal fitting 13 from above. (10) The wooden column 12 is composed of two column components 20. Therefore, the wooden column 12 is less likely to buckle than if it were composed of a single piece of wood. Therefore, the length of the wooden column 12 can be increased, allowing the ceiling height on the first floor to be increased.

[0064] (11) The two pillar components 20 are integrated by being connected with bolts and nuts, so that the strength of the wooden pillar 12 is equivalent to that when the two pillar components 20 are bonded together with adhesive.

[0065] (12) Although not shown, the building 10 may include a cross member extending in the second direction X2. In this embodiment, the cross section of the wooden column 12 is rectangular, and the longitudinal direction of the wooden column 12 in a plan view is parallel to the first direction X1. Therefore, even if the dimension of the cross member in the first direction X1 is large, the cross member can be connected to the side of the wooden column 12. When the dimension of the cross member in the first direction X1 is large, the length of the cross member can be increased, making it easier to create a large space.

[0066] (13) The first pillar component 20a and the second pillar component 20b are connected to each other at three locations: the top, the center, and the bottom. This configuration can further increase the connection strength between the first pillar component 20a and the second pillar component 20b compared to when the first pillar component 20a and the second pillar component 20b are connected to each other at two locations: the top and the bottom.

[0067] (14) The wooden pillar 12 is composed of two pillar components 20 arranged in a row in the first direction X1. This reduces the number of pillar components 20 compared to when a wooden pillar is composed of pillar components arranged in two perpendicular directions, thereby reducing the manufacturing cost of the wooden pillar 12. Therefore, the manufacturing cost of the building 10 can be reduced.

[0068] <Example of change> The above-described embodiment is an example of a form that the building 10 can take, and is not intended to limit the form.
