Description

[Technical field]

[0001] The present invention relates to a structure or the like made of wood. [Background technology]

[0002] Traditionally, in structures that require strength, metal members have been used as the main members (Patent Document 1). The strength of a structure can be ensured by using metal members, but considering the realization of a decarbonized society in recent years, it is preferable to use materials that generate less carbon during the manufacture of the members. Since wood absorbs and fixes carbon dioxide, it is effective to use wood as the main members of a structure in order to realize a decarbonized society. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 1-154944 Summary of the Invention [Problem to be solved by the invention]

[0004] However, wood has a lower strength than metal members, so it may not be possible to use it as the main member of a structure. In addition, although the strength of a structure can be improved by making each piece of wood thicker or larger, this causes problems such as the overall size of the structure increasing and the living space becoming smaller. The present invention has been made in consideration of the above-mentioned problems, and has an object to provide a structure or the like made of wood that can ensure strength. [Means for solving the problem]

[0005] The structure of the present invention is characterized by being constructed by combining a plurality of long angle-shaped pieces of wood compressed in a direction perpendicular to the grain direction. The present invention is a structure having a column portion and a beam portion, wherein the column portion is configured by a long first column member and a long second column member arranged at a distance from each other, with a plurality of column inclined members being spanned between the first column member and the second column member, and wherein the first column member and the second column member are each made of long angle-shaped column wood compressed perpendicular to the grain direction. Effect of the Invention

[0006] According to the present invention, it is possible to provide a structure or the like made of wood that can ensure strength. [Brief description of the drawings]

[0008] Hereinafter, the structure according to the present embodiment will be described with reference to the drawings. The structure of this embodiment will be described by taking as an example a column-beam structure of a truss structure including beams and columns. <First embodiment> Fig. 1 is a perspective view showing an example of a building 1 using multiple beam-column structures 10. Fig. 2 is a front view of the building 1 as seen from the entrance side (front side). Note that in each of the figures including Fig. 1, the right side is illustrated as "right", the left side as "left", the front side as "front", and the rear side as "rear", based on the position when a user faces the entrance 2 of the building 1.

[0009] The building 1 of this embodiment is a long, one-story store (e.g., a restaurant) extending in the front-to-back direction (depth direction) from the entrance 2. The building 1 includes a gable wall 3, a right girder wall 4, a left girder wall 5, a roof 6, and a plurality of column-beam structures 10.

[0010] The gable wall 3 is a wall located opposite the entrance 2. The right side girder wall 4 and the left side girder wall 5 are walls that face each other across the interior living space. In this embodiment, the gable wall 3, the right side girder wall 4 and the left side girder wall 5 are entirely or almost entirely made of transparent materials such as glass so that the outdoors can be seen from the living space. In addition, the gable wall 3, the right side girder wall 4 and the left side girder wall 5 are appropriately equipped with doors that allow users to enter and exit and windows that can be opened and closed. Note that the parts of the right side girder wall 4 that face the kitchen, office, toilet, etc. located indoors are made of non-transparent materials.

[0011] The roof 6 covers the building 1 from above. The roof 6 in this embodiment is a single-slope roof that gradually slopes downward from the left girder wall 5 side to the right girder wall 4 side. Rainwater flowing along the roof 6 drips down from the right girder wall 4 side. The roof 6 in this embodiment is also made of metal folded plates.

[0012] The column-beam structure 10 supports the gable wall 3, the right girder wall 4, the left girder wall 5, and the roof 6. In the building 1, a plurality of column-beam structures 10 are arranged at regular intervals in the front-to-rear direction. In the building 1 of this embodiment, approximately 40 pairs of column-beam structures 10 are arranged in the same direction at intervals of approximately 1000 mm. However, the number and intervals of the column-beam structures 10 can be changed as appropriate depending on the strength and design required for the building 1.

[0013] The main members of the beam-column structure 10 of this embodiment are long angle-shaped wooden pieces 11 compressed perpendicular to the grain direction. By forming them into an angle shape, it is possible to ensure strength compared to a simple board-shaped piece, and by further compressing and densifying the piece, it is possible to ensure even greater strength compared to wood that has simply been cut.

[0014] Here, a manufacturing method of the angle-shaped lumber 11 used in this embodiment will be described with reference to Fig. 3. In this embodiment, the angle-shaped lumber 11 is manufactured from coniferous trees as natural wood. Generally, broad-leaved trees are heavy and hard, making them suitable for use in furniture and interior and exterior materials. On the other hand, coniferous trees are light and have a soft surface, making them unsuitable for use in furniture and interior and exterior materials. However, coniferous trees are easily obtained through planned felling and thinning as a national policy, making them more likely to contribute to decarbonization.

[0015] The angle-shaped wooden piece 11 of this embodiment is manufactured using four plank-shaped wooden pieces 14a-14d. FIG. 3(a) is a diagram showing the state of the plank-shaped wooden pieces 14a-14d before compression. The plank-shaped wooden pieces 14a-14d are plank-shaped pieces cut along the grain from a part of a coniferous tree (here, cypress) that is, for example, uniformly dried (water content of 10% or less) and has no knots. The plank-shaped wooden pieces 14a-14d have the same plank thickness t, which is about 12 mm in this embodiment. The plank-shaped wooden pieces 14a and 14b have the same plank width WA, and the plank-shaped wooden pieces 14c and 14d have the same plank width WB, which is the plank width WA<plank width WB, and the plank width WA+t=plank width WB in this embodiment. The length of the plank-shaped wooden pieces 14a-14d can be changed according to the required length or the length that can be processed by the processing device 200 described later, and is about 3000 mm in this embodiment. In addition, in FIG. 3(a), the lengths of the wooden boards 14a to 14d are shown shortened.

[0016] The plank-shaped wooden pieces 14a and 14b are overlapped with each other's wide surfaces (front and back surfaces, or front and back surfaces) with a shift of the plank thickness t. Similarly, the plank-shaped wooden pieces 14c and 14d are overlapped with each other's wide surfaces with a shift of the plank thickness t. Furthermore, the plank-shaped wooden pieces 14a and 14b are orthogonal to the plank-shaped wooden pieces 14c and 14d, with the plank-shaped wooden pieces 14a and 14b being in contact with the plank-shaped wooden piece 14c and the plank-shaped wooden piece 14b being in contact with the plank-shaped wooden piece 14d. At this time, adhesive is applied between the plank-shaped wooden pieces and the plank-shaped wooden pieces 14c and 14d being in contact with each other. In this way, the two plank-shaped wooden pieces 14a and 14b are in contact with the two plank-shaped wooden pieces 14c and 14d being in contact with each other, so that the uneven surfaces fit together and the contact area increases, allowing for strong adhesion.

[0017] FIG. 3(b) is a diagram showing a state in which the plank-shaped wooden pieces 14a to 14d are compressed using the processing device 200. The processing device 200 has a movable metal mold 201 located on the upper side and a fixed metal mold 203 located on the lower side. The movable metal mold 201 has a protrusion 202 that protrudes downward to shape the inner surface of the angle-shaped wooden piece 11. On the other hand, the fixed metal mold 203 has a recess 204 that is recessed downward to shape the outer surface of the angle-shaped wooden piece 11. The protrusion 202 and the recess 204 are configured to be long in a direction (depth direction) perpendicular to the movable direction of the metal mold 201.

[0018] In the processing device 200, the plank-shaped wooden pieces 14a, 14b and plank-shaped wooden pieces 14c, 14d are arranged perpendicular to each other in the recessed portion 204 of the fixed die 203, and the movable die 201 is lowered from the top to the bottom to compress the plank-shaped wooden pieces 14a to 14d while heating them. Since the protruding portion 202 and the recessed portion 204 are long in the depth direction, the plank-shaped wooden pieces 14a to 14d having a length of about 3000 mm as in this embodiment can be compressed at once. The plank-shaped wooden pieces 14a to 14d are compressed in a direction perpendicular to the grain direction or plastically deformed into a state compressed in the thickness direction. In this way, the angle-shaped wooden piece 11 can be manufactured by integrating the plank-shaped wooden pieces 14a to 14d into an angle shape.

[0019] Fig. 3(c) is a diagram showing the manufactured angle-shaped lumber 11. Here, by further polishing and painting, it becomes a member that can be used for the beam-column structure 10. Note that in Fig. 3(c), the length of the angle-shaped lumber 11 is shown shortened. When viewed along the longitudinal direction, the angle-shaped wood 11 has a corner 12, a side 13A on one side extending from the corner 12 to one side, and a side 13B on the other side extending from the corner 12 to the other side. The side 13A on one side and the side 13B on the other side are perpendicular to each other at the corner 12. The outer and inner surfaces of the corner 12 are curved. On the outer surface of the angle-shaped wood 11, the boundary Bo between the plank wood 14a and the plank wood 14c is located offset from the center of the corner 12 toward the side 13A on one side. On the inner surface of the angle-shaped wood 11, the boundary Bi between the plank wood 14b and the plank wood 14d is located at the center of the corner 12. In this embodiment, at the end of the side 13A on one side, the end of the plank wood 14b is located so as to cover the end of the plank wood 14a, and at the end of the side 13B on the other side, the end of the plank wood 14d is located so as to cover the end of the plank wood 14c.

[0020] The angle-shaped wooden piece 11 compressed in this manner has the same thickness T at the side 13A on one side and the side 13B on the other side, which is about 10 mm in this embodiment. That is, the thickness T of the side 13A on one side is smaller than the thickness 2t of the overlapping plank-shaped wooden pieces 14a and 14b before compression, and the thickness T of the side 13B on the other side is smaller than the thickness 2t of the overlapping plank-shaped wooden pieces 14c and 14d before compression. The compression ratio of the angle-shaped wooden piece 11 in this embodiment is about 58.3% because (24 mm-10 mm)÷24 mm=about 0.58. In this embodiment, the angle-shaped wooden piece 11 is compressed so that its specific gravity becomes about 1.0 (0.9 to 1.1). The compression ratio of the angle-shaped wooden piece 11 is changed according to the required strength, size, and type of conifer (cypress, cedar, pine, etc.).

[0021] 4 is a perspective view showing an example of the configuration of the column-beam structure 10. The column-beam structure 10 is configured in a generally gate-like shape by a pair of left and right column portions 20 and a beam portion 50. The space surrounded by the pair of column portions 20 and the beam portion 50 is open in the front-rear direction, allowing users to pass through. The column-beam structure 10 of this embodiment is configured generally symmetrically with respect to a center line C in the left-right direction. 5 shows the metal members in the beam-column structure 10 by dashed lines. The compressed angle-shaped timber 11 has improved strength, but the beam-column structure 10 is reinforced by using metal members in areas where strength is insufficient.

[0022] The specific configuration of the beam-column structure 10 will be described below. First, the structure of the pillars 20 will be described with reference to Figures 6 to 9. The pillars 20 are formed by combining the above-mentioned multiple angle-shaped wooden pieces 11. Since the pillar-beam structure 10 is configured substantially symmetrically with respect to the center line C in the left-right direction, only the pillar 20 on the left side will be described here, and a description of the pillar 20 on the right side will be omitted.

[0023] FIG. 6 is an exploded perspective view showing a part of the structure of the column portion 20. As shown in FIG. The column section 20 has a first column member 21, a second column member 31, and a plurality of column inclination members 41a-41h. The first column member 21 and the second column member 31 are each elongated along the up-down direction and face each other at a position separated in the left-right direction. The first column member 21 is longer than the second column member 31, and has a length that reaches an upper beam member 51 described later. On the other hand, the second column member 31 is shorter than the first column member 21, and has a length that reaches a lower beam member 61 described later.

[0024] A pair of angle-shaped pieces of wood 11 are used for the first pillar member 21. The angle-shaped pieces of wood 11 used for the first pillar member 21 are referred to as pillar pieces 11A here. The first pillar member 21 is formed by connecting a pair of pillar pieces 11A that are long in the vertical direction in a state where they are arranged side by side in the front-to-rear direction. Specifically, the first pillar member 21 is arranged such that the sides 13A on one side of the pair of pillar pieces 11A are positioned parallel to each other and spaced apart from each other in the front-to-rear direction, and the sides 13B on the other side of the pair of pillar pieces 11A are positioned in a straight line along the front-to-rear direction. In addition, the corners 12 of the pair of pillar pieces 11A are positioned facing each other and spaced apart from each other in the front-to-rear direction, and are positioned outside (left side) of the pillar portion 20.

[0025] The first pillar member 21 is supported on the floor surface by a base member 22 made of metal. Fig. 7 is a diagram showing the support structure of the first pillar member 21. Fig. 7(a) is a diagram showing the support structure as seen from above (cross-sectional view along line II). Fig. 7(b) is a diagram showing the support structure as seen from the rear, in which the rear pillar wooden piece 11A of the pair of pillar wooden pieces 11A is omitted. The base member 22 has a base portion 23 and a support portion 24 protruding upward from the top surface of the base portion 23. The base member 22 can be fixed to the floor surface by inserting anchor bolts 25 fixed to the floor surface into fixing holes in the base portion 23 and fastening them with nuts. The pair of pillar wooden pieces 11A can be fixed to the base member 22 by sandwiching the support portion 24 from the front and back between a pair of pillar wooden pieces 11A and inserting connecting bolts 26 into each bolt hole in the side portion 13A and the bolt holes in the support portion 24 and fastening them with nuts.

[0026] The first pillar member 21 also supports a frame member 27. Here, the frame member 27 is a vertically long metal member located on the outside of the first pillar member 21. The frame member 27 supports the left girder wall 5 and the like. The frame member 27 has mounting portions 28 spaced apart vertically on the side surface facing the first pillar member 21. The frame member 27 can be fixed to the first pillar member 21 by sandwiching the mounting portions 28 from the front and rear between a pair of pillar wooden pieces 11A, inserting bolts through each bolt hole in the side portion 13A and the bolt holes in the mounting portions 28, and fastening them with nuts.

[0027] As shown in FIG. 6, a pair of angle-shaped pieces of wood 11 are used for the second pillar member 31. The angle-shaped pieces of wood 11 used for the second pillar member 31 are referred to as pillar pieces 11B here. The second pillar member 31 is connected to the pair of pillar pieces 11B in a state where they are arranged side by side in the front-rear direction. Specifically, the second pillar member 31 is arranged such that the side portions 13A on one side of the pair of pillar pieces 11B are positioned parallel to each other and spaced apart from each other in the front-rear direction, and the side portions 13B on the other side of the pair of pillar pieces 11B are positioned in a straight line along the front-rear direction. In addition, the corner portions 12 of the pair of pillar pieces 11B are positioned facing each other and spaced apart from each other in the front-rear direction, and are positioned on the inner side (right side) of the pillar portion 20.

[0028] The second pillar member 31 is supported on the floor surface by a base member 32 made of metal. Fig. 8 is a diagram showing the support structure of the second pillar member 31. Fig. 8(a) is a diagram seen from above (cross-sectional view along line II-II). Fig. 8(b) is a diagram showing the support structure seen from the rear, in which the rear pillar wooden piece 11B of the pair of pillar wooden pieces 11B is omitted. The base member 32 has a base portion 33 and a support portion 34 protruding upward from the top surface of the base portion 33. The base member 32 can be fixed to the floor surface by inserting anchor bolts 35 fixed to the floor surface into fixing holes in the base portion 33 and fastening them with nuts. The pair of pillar wooden pieces 11B can be fixed to the base member 32 by sandwiching the support portion 34 from the front and rear between a pair of pillar wooden pieces 11B and inserting connecting bolts 36 into each bolt hole in the side portion 13A and the bolt holes in the support portion 34 and fastening them with nuts.

[0029] As shown in FIG. 4 and FIG. 5, the column inclination members 41 (41a to 41h) are connected in a state of being diagonally bridged between the first column member 21 and the second column member 31. The column section 20 of this embodiment has a plurality of (here, eight) column inclination members 41a to 41h. The column inclination members 41a to 41h are made of long plank-shaped wood. The plank-shaped wood is wood compressed in a direction perpendicular to the grain direction or in the thickness direction. The column inclination members 41a to 41h may be made of angle-shaped wood 11 or may be made of uncompressed wood. The first to seventh column inclination members 41a to 41g from the bottom are each made of a single plank-shaped wood. On the other hand, the eighth column inclination member 41h from the bottom is made of a pair of plank-shaped wood 42 (see FIG. 13 described later).

[0030] The first column inclined member 41a is diagonally bridged between the first column member 21 and the second column member 31 with the first column member 21 side facing up and the second column member 31 side facing down. The second column inclined member 41b is diagonally bridged between the first column member 21 and the second column member 31 with the first column member 21 side facing downward and the second column member 31 side facing upward.

[0031] Fig. 9 shows the connection structure between the first pillar member 21 and the pillar inclined members 41a and 41b. Fig. 9(a) shows the connection structure seen from above (cross-sectional view taken along line III-III). Fig. 9(b) shows the connection structure seen from the rear, with the rear pillar wooden piece 11A of the pair of pillar wooden pieces 11A omitted. Fig. 9(c) shows the connection structure seen from the right (cross-sectional view taken along line IV-IV). The left end portions of the column inclined members 41a and 41b are positioned adjacent to each other vertically. The left end portions of the column inclined members 41a and 41b are sandwiched from the front and rear by a pair of column wooden pieces 11A of the first column member 21, and the connecting bolts 43 are inserted into the bolt holes of the side portions 13A and the bolt holes of the column inclined member 41a and fastened with nuts to be fixed to the first column member 21. The left end portions of the column inclined members 41a and 41b are tapered (cut) so that the ends do not interfere with each other and do not protrude from the first column member 21.

[0032] Similarly, the right end portions of the column inclined members 41a and 41b can be fixed to the second column member 31 by sandwiching them from the front and rear between a pair of column wooden pieces 11B of the second column member 31, inserting a connecting bolt 43 into the bolt hole of the side portion 13A and the bolt hole of the column inclined member 41a, and fastening them with a nut. The right end portions of the column inclined members 41a and 41b are processed (cut) into a tapered shape so as not to interfere with the base member 32 or other column inclined members and not to protrude from the second column member 31.

[0033] The column inclination members 41c to 41g are also configured similarly to the column inclination members 41a and 41b. On the other hand, the column inclination member 41h has a different connection structure from the other column inclination members 41a to 41g, which will be described later with reference to Figs. 13 and 16.

[0034] Next, the configuration of the beam section 50 will be described with reference to Figures 10 to 12. The beam section 50 is formed by combining the above-mentioned multiple angle-shaped wooden pieces 11. Since the beam-column structure 10 is configured to be substantially symmetrical with respect to the center line in the left-right direction, the left side of the beam section 50 will be mainly described here, and the right side will not be described.

[0035] FIG. 10 is an exploded perspective view showing a configuration of a portion of the beam portion 50. As shown in FIG. The beam section 50 has an upper beam member 51, a lower beam member 61, and multiple beam inclination members 71. The upper beam member 51 and the lower beam member 61 are each long in the left-right direction and face each other at positions spaced apart in the up-down direction. The upper beam member 51 is longer than the lower beam member 61, and has a length that reaches the first pillar members 21 located separately on the left and right. On the other hand, the lower beam member 61 is shorter than the upper beam member 51, and has a length that reaches the second pillar members 31 located separately on the left and right.

[0036] A pair of angle-shaped pieces of wood 11 are used for the upper beam member 51. The angle-shaped pieces of wood 11 used for the upper beam member 51 are referred to as beam wood pieces 11C here. The upper beam member 51 is connected to a pair of beam wood pieces 11C that are long in the left-right direction and arranged side by side in the front-rear direction. Specifically, the upper beam member 51 is positioned such that the sides 13A on one side of the pair of beam wood pieces 11C are positioned parallel to each other and spaced apart from each other in the front-rear direction, and the sides 13B on the other side of the pair of beam wood pieces 11C are positioned in a straight line along the front-rear direction. In addition, the corners 12 of the pair of beam wood pieces 11C are positioned facing each other and spaced apart from each other in the front-rear direction, and are positioned above the beam portion 50.

[0037] The upper beam member 51 has upper connection members 52a, 52b for connecting the beam inclined member 71 spanning between the upper beam member 51 and the lower beam member 61. The upper connection member 52a is located at the center in the left-right direction of the upper beam member 51, and the upper connection member 52b is located a certain distance away from the center. Figure 11 is a diagram showing the configuration around the upper connecting member 52a of the upper beam member 51. Figure 11(a) is a diagram showing the configuration around the upper connecting member 52a as seen from the left side (cross-sectional view taken along line VV). Figure 11(b) is a diagram showing the configuration around the upper connecting member 52a as seen from the rear, with the rear beam wooden piece 11C of the pair of beam wooden pieces 11C omitted. The upper connection member 52a is made of metal, and has a base portion 53, connection portions 54L and 54R, and a receiving portion 55.

[0038] The base portion 53 is plate-shaped and is located between a pair of beam wooden pieces 11C. The upper connecting member 52a can be fixed to the pair of beam wooden pieces 11C by sandwiching the base portion 53 between the pair of beam wooden pieces 11C from the front and rear and inserting connecting bolts 56 into the bolt holes in the side portion 13A and the bolt holes in the base portion 53 and fastening them with nuts. Washers 57, through which connecting bolts 56 are inserted, are disposed between the base portion 53 and the front beam wooden piece 11C, and between the base portion 53 and the rear beam wooden piece 11C.

[0039] The connecting portions 54L, 54R are plate-shaped, and extend diagonally downward from the base portion 53 on the left and right. The connecting portions 54L, 54R protrude downward from between a pair of beam wooden pieces 11C, and a beam inclined member 71 is connected to each of the connecting portions 54L, 54R. The receiving portion 55 is located on the upper side of the base portion 53 and is exposed upward from a pair of beam wooden pieces 11C. The receiving portion 55 is formed in a substantially C-shape that opens upward when viewed from the rear side, and receives the load of the roof member 58 from above. Here, the roof member 58 is a metal member that is long in the front-rear direction so as to straddle a plurality of column-beam structures 10. As shown in FIG. 5, the roof member 58 of this embodiment is disposed in the center and at both left and right ends in the left-right direction, and indirectly supports the roof 6. By connecting the receiving portion 55 and the roof member 58, the roof member 58 can be fixed to the upper beam member 51 via the upper connecting member 52a.

[0040] The upper connection member 52b does not have the receiving portion 55 of the above-mentioned upper connection member 52a, and detailed description thereof will be omitted.

[0041] As shown in FIG. 10, a pair of angle-shaped pieces of wood 11 is used for the lower beam member 61. The angle-shaped piece of wood 11 used for the lower beam member 61 is referred to as a beam piece 11D here. The lower beam member 61 is connected to a pair of beam pieces 11D that are long in the left-right direction and arranged side by side in the front-rear direction. Specifically, the lower beam member 61 is positioned such that the sides 13A on one side of the pair of beam pieces 11D are positioned parallel to each other and spaced apart from each other in the front-rear direction, and the sides 13B on the other side of the pair of beam pieces 11D are positioned in a straight line along the front-rear direction. In addition, the corners 12 of the pair of beam pieces 11D are positioned facing each other and spaced apart from each other in the front-rear direction, and are located below the beam portion 50.

[0042] The lower beam member 61 has a lower connection member 62 for connecting a beam inclination member 71 that spans between the lower beam member 61 and the upper beam member 51, and a reinforcing plate 68. The lower connection member 62 is positioned on the lower beam member 61 at a regular interval in the left-right direction. Figure 12 is a diagram showing the configuration around the lower connecting member 62 of the lower beam member 61. Figure 12(a) is a diagram showing the configuration around the lower connecting member 62 as seen from the left side (cross-sectional view taken along line VI-VI). Figure 12(b) is a diagram showing the configuration around the lower connecting member 62 as seen from the rear, with the rear beam wooden piece 11D of a pair of beam wooden pieces 11D omitted. The lower connection member 62 is made of metal and has a base portion 63 and connection portions 64L and 64R. Note that the lower connection member 62 has a similar configuration to the upper connection member 52b, and therefore a description thereof will be omitted where appropriate.

[0043] The base portion 63 is plate-shaped and is located between a pair of beam wooden pieces 11D. The base portion 63 is sandwiched between the pair of beam wooden pieces 11D from the front and rear, and connecting bolts 66 are inserted into the bolt holes in the side portions 13A and the bolt holes in the base portion 63 and fastened with nuts, thereby fixing the lower connecting member 62 to the pair of beam wooden pieces 11D. A washer 67 with the connecting bolt 66 inserted therethrough is disposed between the base portion 63 and the front beam wooden piece 11D.

[0044] The connecting portions 64L, 64R are plate-shaped and extend upward from the base portion 63 on the left and right sides. The connecting portions 64L, 64R protrude upward from between a pair of beam wooden pieces 11D, and a beam inclined member 71 is connected to each of them.

[0045] The reinforcing plate 68 is a metal plate and is positioned between the pair of beam wooden pieces 11D. Specifically, the reinforcing plate 68 is disposed between the pair of beam wooden pieces 11D, between the base portion 63 of each lower connecting member 62 and the rear beam wooden piece 11D. The reinforcing plate 68 is long in the left-right direction and has approximately the same length as the pair of beam wooden pieces 11D.

[0046] The beam inclination member 71 is connected in a state of being bridged diagonally between the upper beam member 51 and the lower beam member 61. The beam section 50 of this embodiment has a plurality of (here, eight) beam inclination members 71. Each beam inclination member 71 uses a pair of long wooden planks 72. The wooden planks are wooden planks compressed in a direction perpendicular to the grain direction or compressed in the thickness direction. The beam inclination member 71 may use angle-shaped wooden planks 11 or uncompressed wooden planks.

[0047] Of the adjacent beam inclination members 71 on the left and right, the beam inclination member 71 on one side is diagonally bridged between the upper beam member 51 and the lower beam member 61 with the right side on top and the left side on the bottom. On the other hand, of the adjacent beam inclination members 71 on the left and right, the beam inclination member 71 on the other side is diagonally bridged between the upper beam member 51 and the lower beam member 61, with the left side on top and the right side on the bottom.

[0048] As shown in Figure 11, the upper end of the beam inclined member 71 on one side can be fixed to the upper beam member 51 by sandwiching the connection portion 54L that protrudes toward the downward side of the upper connecting members 52a, 52b between a pair of wooden planks 72 from the front and back, and inserting connecting bolts 73 into each bolt hole of the wooden planks 72 and the bolt holes of the connection portion 54L and fastening them with nuts. Similarly, the upper end of the beam inclination member 71 on the other side can be fixed to the upper beam member 51 by sandwiching the connection portion 54R that protrudes toward the downward side of the upper connecting members 52a, 52b between a pair of wooden planks 72 from the front and back, and inserting connecting bolts 73 into each bolt hole of the wooden planks 72 and the bolt hole of the connection portion 54R and fastening them with nuts. In addition, the upper end of the beam inclined member 71 is processed (cut) so that it is horizontal and spans diagonally between the upper beam member 51 and the lower beam member 61 so that it can contact the lower ends of a pair of beam wooden pieces 11C in the left-right direction.

[0049] Furthermore, as shown in Figure 12, the lower end of the beam inclined member 71 on one side can be fixed to the lower beam member 61 by sandwiching the connection portion 64R protruding toward the upper side of the lower connecting member 62 between a pair of wooden planks 72 from the front and rear, and inserting connecting bolts 73 into each bolt hole of the wooden planks 72 and the bolt holes of the connection portion 64R and fastening them with nuts. Similarly, the lower end of the beam inclined member 71 on the other side can be fixed to the lower beam member 61 by sandwiching the connection portion 64L extending toward the upper side of the lower connecting member 62 between a pair of wooden planks 72 from the front and rear, and inserting connecting bolts 73 into each bolt hole of the wooden planks 72 and the bolt holes of the connection portion 64L and fastening them with nuts. In addition, the lower end of the beam inclined member 71 is processed (cut) so that it is horizontal and spans diagonally between the upper beam member 51 and the lower beam member 61 so that it can contact the upper ends of a pair of beam wooden pieces 11D in the left-right direction.

[0050] Next, the configuration of the corner portion 80 where the column portion 20 and the beam portion 50 intersect will be described with reference to Fig. 13 to Fig. 16. Note that only the left corner portion 80 will be described, and a description of the right corner portion 80 will be omitted.

[0051] FIG. 13 is an exploded perspective view showing the configuration of the corner portion 80. Here, the corner portion where the first pillar member 21 and the upper beam member 51 intersect is called the outer corner portion 81. In the outer corner portion 81, the upper end of the first pillar member 21 and the left end of the upper beam member 51 are processed (cut) to have inclined surfaces so that the first pillar member 21 and the upper beam member 51 butt against each other perpendicularly. On the other hand, the corner portion where the second pillar member 31 and the lower beam member 61 intersect is called the inner corner portion 91. In the inner corner portion 91, the upper end of the second pillar member 31 and the left end of the lower beam member 61 are processed (cut) to have inclined surfaces so that the second pillar member 31 and the lower beam member 61 butt against each other perpendicularly.

[0052] The outer corner portion 81 has an outer corner connection member 82 for connecting a corner inclined member 111 that bridges between the inner corner portion 91 and the outer corner portion 81. The outer corner connection member 82 is located so as to bridge between the first pillar member 21 and the upper beam member 51. Fig. 14 is a diagram showing the configuration around the outer corner connection member 82. Fig. 14(a) is a diagram showing the configuration around the outer corner connection member 82 as seen from the rear side. In Fig. 14(a), the rear column wooden piece 11A of the pair of column wooden pieces 11A of the first column member 21 is omitted, the rear beam wooden piece 11C of the pair of beam wooden pieces 11C of the upper beam member 51 is omitted, and the rear plate wooden piece 112 of the pair of plate wooden pieces 112 of the corner inclined member 111 is omitted. Fig. 14(b) is a diagram showing the configuration around the outer corner connection member 82 as seen from the right side (cross-sectional view taken along line VII-VII). The corner outer connection member 82 is made of metal, and has a base portion 83, a connection portion 85, and a receiving portion 86. The base portion 83 and the connection portion 85 are integrally formed.

[0053] The base portion 83 is plate-shaped and has a column-side base portion 84a and a beam-side base portion 84b. The column-side base portion 84a is long in the up-down direction and is located between the pair of column wooden pieces 11A of the first column member 21. The column-side base portion 84a is sandwiched between the pair of column wooden pieces 11A from the front and rear, and connecting bolts 87 are inserted into the bolt holes of the side portion 13A and the bolt holes of the column-side base portion 84a and fastened with nuts, thereby fixing the corner outer connection member 82 to the pair of column wooden pieces 11A. Washers 88, through which connecting bolts 87 are inserted, are disposed between the column-side base portion 84a and the front column wooden piece 11A, and between the column-side base portion 84a and the rear column wooden piece 11A. The beam-side base portion 84b is long in the left-right direction and is located between a pair of beam timbers 11C of the upper beam member 51. The beam-side base portion 84b is sandwiched between the pair of beam timbers 11C from the front and rear, and the corner outer connection member 82 can be fixed to the pair of beam timbers 11C by inserting connecting bolts 87 into each bolt hole of the side portion 13A and the bolt hole of the beam-side base portion 84b and fastening them with nuts. Washers 88, through which connecting bolts 87 are inserted, are disposed between the beam-side base portion 84b and the front beam timber 11C, and between the beam-side base portion 84b and the rear beam timber 11C.

[0054] The connecting portion 85 is plate-shaped and extends obliquely downward from the base portion 83. The connecting portion 85 protrudes downward from between a pair of column wooden pieces 11A and between a pair of beam wooden pieces 11C, and is connected to the corner inclined members 111. The receiving portion 86 is located above the base portion 83, and is exposed upward from the pair of beam wooden pieces 11C. The receiving portion 86 is formed in a roughly C-shape that opens upward when viewed from the rear, and receives the load of the roof member 58 from above. By connecting the receiving portion 86 to the roof member 58, the roof member 58 can be fixed to the upper beam member 51 via the corner outer connection member 82.

[0055] The mounting portion 28 of the frame member 27 is located below the column-side base portion 84a of the corner outer connection member 82. The mounting portion 28 is sandwiched from the front and rear by a pair of column wooden pieces 11A, and bolts are inserted through each bolt hole in the side portion 13A and the bolt holes in the mounting portion 28 and fastened with nuts.

[0056] 13, the inner corner portion 91 has a corner inner connection member 92 for connecting a corner inclined member 111 that bridges between the inner corner portion 91 and the outer corner portion 81. The corner inner connection member 92 is located so as to bridge between the second pillar member 31 and the lower beam member 61. FIG. 15 is a diagram showing the configuration around the inner corner connection member 92. FIG. 15(a) is a diagram showing the configuration around the inner corner connection member 92 as seen from the rear side. In FIG. 15(a), the rear column wooden piece 11B of the pair of column wooden pieces 11B of the second column member 31 is omitted, the rear beam wooden piece 11D of the pair of beam wooden pieces 11D of the lower beam member 61 is omitted, the rear plate-shaped wooden piece 112 of the pair of plate-shaped wooden pieces 112 of the corner inclined member 111 is omitted, the rear plate-shaped wooden piece 42 of the pair of plate-shaped wooden pieces 42 of the seventh column inclined member 41h is omitted, and the rear plate-shaped wooden piece 72 of the pair of plate-shaped wooden pieces 72 of the beam inclined member 71 is omitted. FIG. 15(b) is a diagram showing the configuration around the inner corner connection member 92 as seen from the right side (VIII-VIII cross-sectional view). The corner inner connection member 92 is made of metal and has a base portion 93, a beam connection portion 96, a column connection portion 97, and a corner connection portion 98. The base portion 93, the beam connection portion 96, the column connection portion 97, and the corner connection portion 98 are integrally formed.

[0057] The base portion 93 is plate-shaped and has an insertion hole 94 (see FIG. 13), a column-side base portion 95a, and a beam-side base portion 95b. The insertion hole 94 is located approximately at the center of the base portion 93. The insertion hole 94 is a hole for inserting a long member 131a (described later) that is long in the front-rear direction in order to connect adjacent column-beam structures 10 in the front-rear direction.

[0058] The column-side base portion 95a is long in the up-down direction and is located between a pair of column wooden pieces 11B of the second column member 31. The column-side base portion 95a is sandwiched between the pair of column wooden pieces 11B from the front and rear, and the corner inner connection member 92 can be fixed to the pair of column wooden pieces 11B by inserting connecting bolts 99 into the bolt holes of the side portion 13A and the bolt holes of the column-side base portion 95a and fastening them with nuts. Washers 100, through which connecting bolts 99 are inserted, are disposed between the column-side base portion 95a and the front column wooden piece 11B, and between the column-side base portion 95a and the rear column wooden piece 11B. The beam-side base portion 95b is long in the left-right direction and is located between a pair of beam wooden pieces 11D of the lower beam member 61. The corner inner connection member 92 can be fixed to the pair of beam wooden pieces 11D by sandwiching the beam-side base portion 95b between the front and rear of the pair of beam wooden pieces 11D and inserting connecting bolts 99 into the bolt holes of the side portion 13A and the bolt holes of the beam-side base portion 95b and fastening them with nuts. A washer 100 with a connecting bolt 99 inserted therethrough is disposed between the beam-side base portion 95b and the front beam wooden piece 11D, and a reinforcing plate 68 is disposed between the beam-side base portion 95b and the rear beam wooden piece 11D.

[0059] The beam connection part 96 is plate-shaped and extends obliquely upward from the base part 93 toward the opposite side from the outer corner part 81. The beam connection part 96 protrudes upward from between a pair of beam wooden pieces 11D, and is connected to the beam inclined member 71. The lower end of the beam inclined member 71 can be fixed to the lower beam member 61 by sandwiching the beam connection part 96 from the front and rear with a pair of plate-shaped wooden pieces 72, and inserting connecting bolts 99 through each bolt hole of the plate-shaped wooden pieces 72 and the bolt holes of the beam connection part 96 and fastening them with nuts.

[0060] The column connection part 97 is plate-shaped and extends obliquely downward from the base part 93. The column connection part 97 protrudes downward from between a pair of column wooden pieces 11B, and the column inclined member 41h is connected to the column connection part 97. The upper end of the column inclined member 41h can be fixed to the second column member 31 by sandwiching the column connection part 97 between the pair of plate-shaped wooden pieces 42 from the front and rear, inserting connecting bolts 99 into each bolt hole of the plate-shaped wooden pieces 42 and the bolt hole of the column connection part 97, and fastening them with nuts. The lower end of the column inclined member 41h is connected to the column connection part 120 of the first column member 21. The configuration in which the column inclined member 41h is connected to the column connection part 120 of the first column member 21 will be described later with reference to FIG. 16.

[0061] The corner connection parts 98 are plate-shaped and extend obliquely upward from the base part 93 toward the outer corner parts 81. The corner connection parts 98 protrude upward from between a pair of column wooden pieces 11B and between a pair of beam wooden pieces 11D, and are connected to the corner inclined members 111.

[0062] The corner inclined member 111 is connected in a state of bridging diagonally between the outer corner portion 81 and the inner corner portion 91. Each corner inclined member 111 uses a pair of long wooden planks 112. The wooden planks 112 are wooden planks compressed in a direction perpendicular to the grain direction or compressed in the thickness direction. The corner inclined member 111 may use the angled wooden plank 11 or may use uncompressed wooden plank.

[0063] As shown in Figures 13 and 14, the upper end of the corner inclined member 111 can be fixed to the first column member 21 and the upper beam member 51 by sandwiching the connection portion 85, which protrudes toward the underside of the corner outer connecting member 82, between a pair of plank-shaped wooden pieces 112 from the front and rear, and inserting connecting bolts 87 into each bolt hole in the plank-shaped wooden pieces 112 and the bolt holes in the connection portion 85 and fastening them with nuts. As shown in Figures 13 and 15, the lower end of the corner inclined member 111 can be fixed to the second column member 31 and the lower beam member 61 by sandwiching the corner connection portion 98, which protrudes toward the upper side of the corner inner connecting member 92, from the front and rear between a pair of plank-shaped wooden pieces 112, and inserting connecting bolts 99 into each bolt hole in the plank-shaped wooden pieces 112 and the bolt holes in the corner connection portion 98 and fastening them with nuts.

[0064] In addition, the upper end of the corner inclined member 111 is processed (cut) to be tapered so that it can contact a pair of pillar wooden pieces 11A in the vertical direction and a pair of beam wooden pieces 11C in the horizontal direction. On the other hand, the lower end of the corner inclined member 111 is processed (cut) to be concave so that it can contact a pair of pillar wooden pieces 11B in the vertical direction and a pair of beam wooden pieces 11D in the horizontal direction.

[0065] Fig. 16 is a diagram showing the configuration around the post connection member 120. Fig. 16(a) is a diagram showing the configuration around the post connection member 120 as seen from the rear side. In Fig. 16(a), the rear post wooden piece 11A of the pair of post wooden pieces 11A of the first post member 21 is omitted. Fig. 16(b) is a diagram showing the configuration around the post connection member 120 as seen from the right side, with a portion shown in cross section. The column connection member 120 is made of metal, and has a base portion 121 and a connection portion 122. The base portion 121 and the connection portion 122 are integrally formed.

[0066] The base portion 121 is plate-shaped and is located between the pair of pillar wooden pieces 11A of the first pillar member 21 and directly above the upper end of the pillar inclined member 41g. The base portion 121 is sandwiched from the front and rear by the pair of pillar wooden pieces 11A, and the connecting bolts 123 are inserted through the bolt holes of the side portions 13A and the bolt holes of the base portion 121 and fastened with nuts, thereby fixing the pillar connecting member 120 to the pair of pillar wooden pieces 11A. The connection part 122 is plate-shaped and extends obliquely upward from the base part 121. The connection part 122 protrudes upward from between a pair of pillar wooden pieces 11A, and the pillar inclined member 41h is connected to the connection part 122. The lower end of the pillar inclined member 41h can be fixed to the first pillar member 21 by sandwiching the connection part 122 from the front and rear with a pair of plate-shaped wooden pieces 42, inserting connecting bolts 123 into each bolt hole of the plate-shaped wooden pieces 42 and the bolt hole of the connection part 122, and fastening them with nuts. In this way, the first pillar member 21 can be a structure in which the pillar inclination member 41h is supported using the pillar connection member 120, while the pillar inclination members 41a to 41g are supported using a pair of pillar wooden pieces 11A.

[0067] A plurality of beam-column structures 10 configured as described above are arranged at regular intervals in the front-rear direction. At this time, adjacent beam-column structures 10 in the front-rear direction are connected to each other via elongated metal members 131a and 131b that are long in the front-rear direction. 13, the rear elongated member 131a and the front elongated member 131b are positioned on a straight line along the front-rear direction, and the rear elongated member 131a is connected to the front elongated member 131b through the inner corner portion 91. A male thread is formed at the front end of the rear elongated member 131a. Meanwhile, a joint member 132 is provided at the rear end of the front elongated member 131b so as to be adjustable in the front-rear direction, and a female thread is formed inside.

[0068] FIG. 15(c) is a diagram showing a configuration in which the beam-column structure 10 is supported by long members 131a and 131b, and is a cross-sectional view taken along line IX-IX in FIG. 15(a). The long member 131a passes through the insertion holes 134, 135 of the second column member 31 and the lower beam member 61, the insertion hole 136 of the reinforcing plate 68 (see FIG. 13), the insertion hole 94 of the corner inner connection member 92, and the washer 100. The male thread of the long member 131a is screwed into the female thread of the joint member 132 of the long member 131b. In addition, a nut 133 is screwed into the male thread of the long member 131a on the opposite side of the joint member 132. The second column member 31 and the lower beam member 61 are sandwiched between the joint member 132 and the nut 133 from the front and rear, so that the column-beam structure 10 can be fixed to the long members 131a and 131b. In addition, the long members 131a and 131b of this embodiment are fixed so that a cylindrical or square tubular wood (not shown) fits into the outer circumferential surface of each of them. Therefore, the long members 131a, 131b can be in harmony with the individual pieces of wood that make up the beam-column structure 10.

[0069] In the first pillar member 21 of this embodiment, the length of one pillar wood 11A is insufficient, so the pillar wood 11A is connected in a straight line in the longitudinal direction to ensure the necessary length for the first pillar member 21. Specifically, as shown in FIG. 13, a metal joint plate 130 is placed across the upper pair of pillar woods 11A and the lower pair of pillar woods 11A. The upper part of the joint plate 130 is sandwiched from the front and rear by the upper pair of pillar woods 11A, and the lower part of the joint plate 130 is sandwiched from the front and rear by the lower pair of pillar woods 11A. The upper pair of pillar woods 11A and the lower pair of pillar woods 11A can be joined by inserting connecting bolts into the bolt holes of the side portions 13A and the bolt holes of the joint plate 130 and fastening them with nuts. Similarly, the necessary lengths of the upper beam member 51 and the lower beam member 61 are also ensured by using the joint plate 130. By joining in this manner, the necessary length can be ensured even if the length of the angle-shaped wooden pieces 11 that can be processed by the processing device 200 is short. Also, since each wooden piece can be shortened before assembling the beam-column structure 10, the work of attaching metal members to each wooden piece can be easily performed.

[0070] As described above, the structure of this embodiment uses the long angle-shaped wooden pieces 11 compressed in a direction perpendicular to the grain direction or in the thickness direction, and therefore can ensure strength compared to the case of using general wooden pieces. Therefore, even in parts of the structure where only metal members could be used because of insufficient strength, the strong angle-shaped wooden pieces 11 can be used, which contributes to the realization of a decarbonized society. In addition, by using the compressed angle-shaped wooden pieces 11, the structure can be made lighter than if metal members were used. Furthermore, by using the compressed angle-shaped wooden pieces 11, the heat insulating property and temperature regulating function of the wooden pieces can be utilized, thereby improving the value of the structure.

[0071] <Other embodiments> In the above embodiment, the angle-shaped wooden piece 11 is manufactured using four plank-shaped wooden pieces 14a to 14d, but the present invention is not limited to this case. FIG. 17(a) is a diagram for explaining the second manufacturing method. In the second manufacturing method, an L-shaped piece of wood 210 cut as a whole from a coniferous tree as natural wood is used. As in the first embodiment, the L-shaped piece of wood 210 before compression is placed in the recess 204 of the fixed die 203, and the movable die 201 is lowered from the top to the bottom to compress the L-shaped piece of wood 210 while heating it. Therefore, the L-shaped piece of wood 210 is plastically deformed into a state compressed in a direction perpendicular to the grain direction or in the thickness direction. In this way, an angle-shaped piece of wood 211 can be manufactured from the L-shaped piece of wood 210. Such an angle-shaped piece of wood 211 has excellent aesthetics because it has no adhesive surface.

[0072] FIG. 17(b) is a diagram for explaining the third manufacturing method. In the third manufacturing method, two plank-shaped pieces of wood 220a and 220b are used. As in the first embodiment, the plank-shaped pieces of wood 220a and 220b before compression are arranged in a state in which they are perpendicular to each other and adhesive is applied in the recess 204 of the fixed die 203, and the movable die 201 is lowered from the top to the bottom, and the plank-shaped pieces of wood 220a and 220b are compressed while being heated. Therefore, the plank-shaped pieces of wood 220a and 220b are plastically deformed into a state in which they are compressed in a direction perpendicular to the grain direction or in the thickness direction. In this way, the plank-shaped pieces of wood 220a and 220b can be integrated into an angle-shaped piece of wood 221. Such an angle-shaped piece of wood 221 has a small adhesive surface, and therefore has an excellent aesthetic appearance.

[0073] FIG. 17(c) is a diagram for explaining the fourth manufacturing method. In the fourth manufacturing method, one plank-shaped piece of wood 230 is used. A plurality of grooves 231 are formed in advance along the longitudinal direction of the plank-shaped piece of wood 230 on one wide surface (front or back surface) of the plank-shaped piece of wood 230. The plank-shaped piece of wood 230 is placed on the recess 204 of the fixed die 203, and the movable die 201 is lowered from the top to the bottom, so that the plank-shaped piece of wood 230 is bent at the center so as to fit into the recess 204. The formation of the plurality of grooves 231 makes it easy to bend the plank-shaped piece of wood 230. The movable die 201 is further lowered to compress the bent plank-shaped piece of wood 230 while heating it. Therefore, the plank-shaped piece of wood 230 is plastically deformed into a state in which it is compressed in a direction perpendicular to the grain direction or compressed in the thickness direction. In this way, an angle-shaped piece of wood 232 integrated into an angle shape can be manufactured from the plank-shaped piece of wood 230. Such angle-shaped wooden pieces 232 can be manufactured stably because stress during compression is released.

[0074] The present invention has been described above using the above-mentioned embodiment, but the present invention is not limited to the above-mentioned embodiment and can be modified within the scope of the present invention. For example, some configurations of the above-mentioned embodiment can be combined with other embodiments. In the above-described embodiment, the case has been described where the structure is a column-beam structure 10 formed in a substantially gate shape by the column portions 20 and the beam portions 50, but the present invention is not limited to this case. The structure may be a column 20 or a beam 50. The structure may also be a structure in which metal members have been used up until now. The structure may also be furniture or fixtures. The structure may also be a door and window frame. In any structure, the strength of the structure can be improved by using one angle-shaped wooden piece 11 or combining multiple angle-shaped wooden pieces 11.

[0075] In the above-described embodiment, the reinforcing plate 68 is described as being placed between a pair of beam timbers 11D of the lower beam member 61, but this is not limited to this case, and the reinforcing plate 68 may be placed between a pair of beam timbers of at least one of the upper beam member 51 and the lower beam member 61, and the reinforcing plate 68 may be omitted.
