Description

[Technical Field]

[0001] This invention relates to a wall structure made of wooden materials that uses wooden materials that are standard in shape and lightweight for easy handling as the structural components of the wall for the openings in the column-beam frame, and that achieves excellent workability, high strength, and a lightweight wall itself. [Background technology]

[0002] There is growing attention being paid to the need to prevent global warming, utilize forest resources, and revitalize forestry, and there is also a need to actively utilize wood materials from the perspective of ESG investment and SDGs.

[0003] Wood materials are reusable and are an excellent way to utilize sustainable resources.

[0004] Patent Documents 1 and 2 are known as construction technologies that use wooden materials.

[0005] The "wooden structural member, joint structure for wooden structural members, and construction method thereof" of Patent Document 1 aims to provide a wooden structural member, a joining method for wooden structural members, and a construction method for a joint structure for wooden structural members that enables long-span construction of wooden semi-fireproof structures with a fire margin design, and that is low-cost, has a short delivery time, and is easy to assemble on-site.The wooden member of the wooden structural member is formed by stacking an inner wooden board placed in the center and a pair of outer wooden boards that sandwich the inner wooden board from both sides.A predetermined fire margin layer is provided on the outer periphery of the wooden member, and the area inside this fire margin layer is used as a load-bearing section, making the entire wooden structural member semi-fireproof.

[0006] The "shear wall" of Patent Document 2 aims to provide a shear wall with excellent earthquake resistance using wood-based materials, and the shear wall is installed within the structural plane of a column-beam frame. The shear wall includes a wooden wall portion formed by arranging multiple wooden boards with their longitudinal grain direction in a row, and a closing portion formed by closing the gap between the periphery of the wooden wall portion and the column-beam frame with mortar. The angle of the wooden boards is the angle of the diagonal of the column-beam frame. When a horizontal external load is applied to the column-beam frame due to an earthquake or other event, a tensile or compressive force acts in the diagonal direction within the structural plane of the column-beam frame. Because the wooden boards have a high Young's modulus and strength in the grain direction, they can sufficiently resist this tensile or compressive force, thereby demonstrating excellent earthquake resistance. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-14154 [Patent Document 2] Patent Publication No. 2021-147816 Summary of the Invention [Problem to be solved by the invention]

[0008] In the wall of Patent Document 2, the multiple wooden boards arranged within the structural surface must be shaped to different dimensions to match the column and beam dimensions in the diagonal direction specific to each column-beam frame, posing a problem in that manufacturing the wooden boards is time-consuming.

[0009] Furthermore, when wooden boards are used to span the diagonal corners of a column-beam structure, they become quite large, which makes it difficult to take full advantage of the advantage of wooden boards being lightweight, and also makes them difficult to install.

[0010] The present invention was devised in view of the above-mentioned problems of the prior art, and aims to provide a wall structure made of wooden materials that is easy to work with, has high strength, and is lightweight, and that uses wooden materials that have a fixed shape and can be easily handled for the openings in the post-and-beam structure as the structural components of the wall. [Means for solving the problem]

[0014] In the gap between the hypotenuse of the octagonal block and the pillar or beam, a sealing block is arranged and adhered to the hypotenuse and the pillar or beam in order to seal the gap.

The octagonal blocks are made of a composite material in which a plurality of octagonal plate pieces are stacked and integrated in the width direction of the columns and beams, and one of the inclined portions of the octagonal plate pieces that form the oblique sides of the pair of two pairs of the octagonal blocks is The inclined portions of one set of octagonal boards are formed parallel to the direction of the fibers of the wood material, and the inclined portions of another set of octagonal boards are formed intersecting the direction of the fibers of the wood material, so that the directions of the fibers of the wood material of these octagonal boards adjacent in the width direction of the column and the beam intersect, and the multiple octagonal blocks are arranged inside the opening with their equal-length hypotenuses facing each other, and are arranged vertically and horizontally so that the vertical sides of the octagonal blocks facing the column face the column and the horizontal sides of the octagonal blocks facing the beam face the beam, thereby constructing a wall.

DETAILED DESCRIPTION OF THE INVENTION

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a wall structure made of wood materials according to the present invention will be described in detail below with reference to the accompanying drawings.

[0025] As shown in FIG. 1, a column-and-beam frame consisting of columns 2 and beams 3 is partitioned by a pair of columns 2 on the left and right and a pair of beams 3 on the top and bottom, forming a rectangular opening 4.

[0026] A wall 1 made of wood material is constructed in this opening 4, and the wall 1 is adhered to columns 2 and beams 3 to form a wall structure.

[0027] In the first embodiment, as shown in Figures 1 to 3, the wall 1 is composed of multiple octagonal blocks 5 made of wooden material of the same size that are lined up and stacked in the opening portion 4, and sealing blocks 6, 7 made of wooden material that seal gaps that occur between these octagonal blocks 5 and the columns 2 and beams 3.

[0028] The octagonal block 5 has a constant thickness, and its outer contour has a pair of two horizontal sides x, one above the other, that are parallel to each other and of equal length, a pair of two vertical sides y, one below the other, that are parallel to each other and of equal length, and four pairs of oblique sides w, that are parallel to each other and of equal length, connecting the vertical sides y and the horizontal sides x.

[0029] In the illustrated example, the octagonal block 5 is a regular octagon with eight sides x, y, and w all having the same length.

[0030] The octagonal block 5 may be a shape other than a regular octagon, and for example, the length of the vertical side y and the length of the horizontal side x may be different.

[0031] In the following description, an octagonal block 5 having a regular octagon will be described, but the same understanding can be given to an octagonal block 5 that is not a regular octagon.

[0032] The sealing blocks 6, 7 have a uniform thickness that matches the thickness of the octagonal block 5, and the block 6 has an isosceles trapezoidal outer contour, and the block 7 has an isosceles right triangle shape.

[0033] The isosceles trapezoidal block 6 has a shorter apex side txy that is equal in length to the vertical side y and horizontal side x of the octagonal block 5, a hypotenuse tw that is equal in length to the hypotenuse w of the octagonal block 5, and a longer base side tb that is (1 + √2) times the length of the vertical side y and (1 + √2) times the length of the horizontal side x of the octagonal block 5.

[0034] The right-angled isosceles triangular block 7 has a right-angled apex angle and a base rb opposite it that are equal in length to the hypotenuse w of the octagonal block 5, and the two hypotenuses rw on either side of the apex angle are each 1 / √2 the length of the vertical side y and horizontal side x of the octagonal block 5.

[0035] First, we will explain the arrangement of the octagonal blocks 5 and sealing blocks 6, 7 inside the opening 4. The octagonal blocks 5 are arranged vertically and horizontally in the vertical and horizontal directions of the opening 4.

[0036] In this case, adjacent octagonal blocks 5 are always arranged so that their hypotenuses w face each other. That is, as shown in Figure 1, taking one octagonal block 5 as an example, the blocks are arranged so that each of the four hypotenuses w faces one of the hypotenuses w of the four surrounding octagonal blocks 5.

[0037] As a result, two octagonal blocks 5 are arranged on each of the right and left sides of the octagonal block 5, spaced apart by the length of the vertical side y.

[0038] Similarly, two octagonal blocks 5 are arranged on each of the upper and lower sides of the octagonal block 5, spaced apart by the length of the horizontal side x.

[0039] The octagonal blocks 5 spaced apart from each other are positioned such that their horizontal sides x face each other and their vertical sides y face each other.

[0040] As a result, an opening S is formed around any one of the octagonal blocks 5 by the other four octagonal blocks 5 with their vertical sides y and horizontal sides x.

[0041] When the surrounding octagonal blocks 5 are viewed from the opening S, the opening S is formed in a square shape by being surrounded by the vertical side y and the horizontal side x of the four octagonal blocks 5 arranged around it.

[0042] Of the octagonal blocks 5, the octagonal blocks 5 facing the column 2 and beam 3 are arranged so that their vertical sides y and horizontal sides x face and contact the column surface 2a and beam surface 3a.

[0043] Therefore, the hypotenuse w of the octagonal block 5 cannot abut against the column surface 2a or the beam surface 3a, and a gap is generated between the hypotenuse w of the octagonal block 5 and the column surface 2a or the beam surface 3a.

[0044] The sealing blocks 6 and 7 are disposed between the oblique side w and the column surface 2a or the beam surface 3a to seal the gap.

[0045] The right-angled isosceles triangular block 7 is disposed in the gap between the corner of the opening portion 4 and the hypotenuse w of the octagonal block 5 in the shape of a right-angled isosceles triangle.

[0046] The isosceles trapezoidal blocks 6 are disposed in the gaps between the hypotenuses w of the octagonal blocks 5 paired in the vertical and horizontal directions and the column surfaces 2a and beam surfaces 3a.

[0047] The isosceles trapezoidal blocks 6 are arranged so that their hypotenuses tw face the hypotenuses w of the two octagonal blocks 5 and their bases tb face the column surfaces 2a and beam surfaces 3a, thereby allowing the top sides txy to combine with the vertical sides y and horizontal sides x of the octagonal blocks 5 to form an opening S.

[0048] The adjacent octagonal blocks 5 are bonded together with adhesive at their opposing hypotenuses w. In this way, the hypotenuses w of the octagonal blocks 5 become the joints with other octagonal blocks 5.

[0049] The octagonal block 5 facing the column 2 has its vertical side y, which faces the column 2, glued to the column surface 2a with adhesive. The octagonal block 5 facing the beam 3 has its horizontal side x, which faces the beam 3, glued to the beam surface 3a with adhesive.

[0050] The octagonal block 5 and the isosceles trapezoidal block 6 are bonded together with adhesive at their oblique sides w and tw.

[0051] The octagonal block 5 and the right-angled isosceles triangular block 7 are bonded together with an adhesive at the hypotenuse w of the octagonal block 5 and the base rb of the right-angled isosceles triangular block 7.

[0052] The base tb of the isosceles trapezoidal block 6 and the hypotenuse rw of the right-angled isosceles triangular block 7 facing the column 2 and beam 3 are bonded to the column surface 2a and beam surface 3a with adhesive.

[0053] As described above, the octagonal block 5 and the sealing blocks 6 and 7 are arranged and bonded inside the opening portion 4, thereby constructing a wall structure.

[0054] The adhesive is preferably an epoxy resin or the like that permeates the wood material, and the strength of the wood material is increased by the adhesive that permeates the bonded surfaces.

[0055] The octagonal block 5 is preferably an octagon in which the length of the hypotenuse w is longer than the vertical side y and / or the horizontal side x, rather than a regular octagon, because this increases the strength of the hypotenuse w to which the adhesive is applied.

[0056] In addition, Figures 1 to 3 show a case where the octagonal block 5 can be directly attached to the column 2 or beam 3 by placing the vertical side y or horizontal side x of the octagonal block 5 against the column surface 2a or beam surface 3a of the opening portion 4. However, depending on the dimensional relationship between the opening portion 4 and the octagonal block 5, a gap may occur between the column 2 or beam 3 and the vertical side y or horizontal side x of the octagonal block 5 facing them, and this gap may prevent the octagonal block 5 from being directly placed against the column surface 2a or beam surface 3a.

[0057] In such cases, as shown in Figure 4, sealing blocks 9 and 10 are used that allow the fit of the octagonal block 5 to be adjusted, and the octagonal block 5 is adhered to the column surface 2a and beam surface 3a via these sealing blocks 9 and 10.

[0058] That is, sealing material formed with a fitting margin for sealing the gap is placed between the column 2 or beam 3 and the vertical side y or horizontal side x of the opposing octagonal block 5. The vertical side y or horizontal side x is then bonded to the sealing material, which is then bonded to the column 2 or beam 3, to construct the wall 1. An example in which the sealing material is incorporated into the above-mentioned sealing blocks 6 and 7 is shown in the figure.

[0059] In the illustrated example, a first sealing block 9 is used to fit into the upper left corner of the opening 4, and has legs 9a protruding from the base corner of the right-angled isosceles triangular block 7, with a thickness equal to the fit allowance and a length approximately half the vertical side y and horizontal side x of the octagonal block 5.

[0060] In accordance with the arrangement of this first sealing block 9, a second sealing block 10 is used below and to the right of the first sealing block 9, aligned with the column surface 2a and beam surface 3a, and has a base portion 10a protruding from the bottom side tb of the isosceles trapezoidal block 6, the thickness of which is the fitting allowance, and which has a length approximately half the vertical side y and horizontal side x of the octagonal block 5 from both sides.

[0061] On the other hand, the upper right corner of the opening 4 is fitted with a third sealing block 11 and a fourth sealing block 12, and an opening S is also formed between these sealing blocks 11, 12 and the octagonal block 5.

[0062] The third sealing block 11 has almost the same shape as the second sealing block 10, and only the protruding dimension of the right-side protruding portion that abuts against the column surface 2a is set to the dimension of the fit between the vertical side y of the octagonal block 5 directly below and the column surface 2a.

[0063] On the other hand, the fourth sealing block 12 is formed based on the second sealing block 10 so as to have an outer shape that fits between the cylindrical surface 2 a and the third sealing block 11 .

[0064] That is, the sealing blocks 9, 10, 11, and 12 are formed with a necessary fit to the above-mentioned sealing blocks 6 and 7, and a sealing material for sealing the gaps is integrally formed.

[0065] By using sealing blocks 9, 10, 11, and 12 with such fit margins, a wall 1 made of octagonal blocks 5 can be constructed inside the opening 4 even if the octagonal blocks 5 cannot be directly placed against the column surface 2a or beam surface 3a.

[0066] Next, a detailed description will be given of the structure of the octagonal block 5. The octagonal block 5 made of a wooden material is formed so as to make use of the fibers f contained in the wooden material.

[0067] Specifically, as shown in Figure 5, the octagonal block 5 is formed so that one pair of hypotenuses w is parallel to the direction of the fibers f of the wood material, and the other pair of hypotenuses w intersects the direction of the fibers f of the wood material at right angles.

[0068] The phrase "the oblique side w is parallel to the direction of the fibers f" means that the oblique side w should be substantially approximately parallel to the direction of the fibers f that are aligned in one direction in the wood material.

[0069] Therefore, when we say that the hypotenuse w intersects with the direction of the fibers f, we mean that the hypotenuse w should be oriented in a direction that essentially intersects with the direction of the fibers f that are aligned in one direction in the wood material.

[0070] It is also preferable that the sealing blocks 6, 7, 9 to 12 are formed in accordance with the direction of the fibers f of the wood material in each octagonal block 5.

[0071] In each octagonal block 5 constructed in this manner, the direction parallel to the direction of the fibers f of the wood material is the strong axis direction SA with respect to the tensile force, and especially the compressive force C, as shown in FIG.

[0072] In each octagonal block 5, the direction intersecting the direction of the fibers f of the wood material is the weak axis direction WA with respect to the compressive force, and especially the tensile force T.

[0073] The octagonal block 5 can be formed in various ways as shown in Figure 6. Figure 6(a) is a side view of a raw material such as a cylindrical log cut in the direction of the grain to form a sawn board.

[0074] FIG. 6(b) is a side view of a composite material in which sawn boards are used as octagonal plate pieces 5a, and these octagonal plate pieces 5a are stacked and integrated.

[0075] In this case, all the octagonal board pieces 5a are overlapped in the width direction of the pillars 2 and the beams 3 so that the orientation of the fibers f of the wood material is substantially approximately the same.

[0076] Figure 6(c) is a side view of a composite material in which thin plates are created from raw material logs, such as cylindrical logs, using a peeling method, and multiple octagonal plate pieces 5a cut from these thin plates are stacked and integrated together.

[0077] In this case as well, all the octagonal plate pieces 5a are overlapped in the width direction of the pillars 2 and the beams 3 so that the orientation of the fibers f of the wood material is substantially approximately the same.

[0078] The multiple octagonal blocks 5 arranged as described above inside the opening portion 4 are arranged and glued together in the vertical and horizontal directions with equal-length hypotenuses w facing each other so that the orientation of the fibers f of the wood material in all of the octagonal blocks 5 is substantially approximately the same.

[0079] Therefore, as shown in Figure 7, inside the opening 4 where octagonal blocks 5 are stacked between the upper and lower beams 3, 3 and lined up between the left and right columns 2, 2, the stress transmission state is such that, as shown in Figure 8, the direction parallel to the direction of the fibers f of the wood material (upward and leftward inclination in the figure; 45° in the case of a regular octagon) is the strong axis direction SA, and the direction intersecting the direction of the fibers f (upward and rightward inclination in the figure; 45° in the case of a regular octagon) is the weak axis direction WA.

[0080] Therefore, a column-and-beam frame equipped with such a wall 1 can provide a structure with more leeway against a rightward external force RF than against a leftward external force LF.

[0081] In a post-and-beam frame in which two adjacent openings 4 are formed, i.e., in a post-and-beam frame in which openings 4 are formed on both sides of a central post 2, walls 1 are constructed inside each of the adjacent openings 4, and the orientation of the fibers f of the wood material of these walls 1 is substantially, approximately, different.

[0082] That is, as shown in Figure 9, the octagonal blocks 5 are arranged to construct each wall 1 so that, with regard to the stress transmission state between adjacent opening portions 4, the strong axis direction SA of one wall 1 is the weak axis direction WA of the other wall 1, and the weak axis direction WA of the other wall 1 is the strong axis direction SA of the one wall 1.

[0083] On the other hand, as shown in FIG. 10, inside the opening 4, at least two walls 1 are constructed in a stacked manner in the width direction of the columns 2 and beams 3.

[0084] Adjacent walls 1 are constructed so that the orientation of the fibers f of the wood material is substantially different from each other.

[0085] In other words, each wall 1 is constructed by arranging the octagonal blocks 5 so that the strong axis direction SA of one wall 1 is the weak axis direction WA of the other wall 1, and the weak axis direction WA of one wall 1 is the strong axis direction SA of the other wall 1.

[0086] These walls 1 are not bonded to each other in the width direction of the columns 2 and beams 3, but are separated from each other and are arranged side by side so that they can move freely relative to each other.

[0087] As a result, as shown in Figure 11, the stress transmission state in this case is such that a column-beam structure is obtained that exerts equal resistance to both a right-direction external force RF and a left-direction external force LF at a single opening 4.

[0088] In the wall structure made of wood material according to the present embodiment described above, a plurality of octagonal blocks 5 made of wood material and having the same dimensions are used, and one set of oblique sides w of the octagonal blocks 5 is formed parallel to the direction of the fibers f of the wood material, and another set of oblique sides w of the octagonal blocks 5 is formed so as to intersect with the direction of the fibers f of the wood material, and the plurality of octagonal blocks 5 are arranged lengthwise and widthwise inside the opening portion 4 with the oblique sides w of equal length facing each other so that the directions of the fibers f of the wood material are all the same. The octagonal blocks 5 are arranged in a direction perpendicular to the wall 1, and the opposing oblique sides w of the octagonal blocks 5 are glued together inside the opening 4, with the vertical side y of the octagonal block 5 facing the column 2 glued to said column 2 and the horizontal side x of the octagonal block 5 facing the beam 3 glued to said beam 3, thereby constructing the wall 1. By aligning the directions of the joined oblique sides w with the fibers f of the wood material, the wall 1 can be given high strength to provide earthquake resistance, even though it is made of wood.

[0089] Furthermore, the octagonal blocks 5 made of wooden material that are the constituent members of the wall 1 have a standard shape compared to the openings 4 of the column-and-beam structure, and can be made lightweight for easy handling, making them easy to install and also enabling the weight of the wall 1 itself to be reduced.

[0090] By combining octagonal blocks 5 formed as single units, the strength of the octagonal blocks 5 can be ensured high, while openings S that ensure lighting and ventilation can be formed rationally in the wall 1.

[0091] The octagonal blocks 5 themselves are very strong, and the walls 1 are constructed by bonding the octagonal blocks 5 together and to the columns 2 and beams 3, so there is no noise, vibration, or dust generated, and the walls 1 can be constructed without the need for any maintenance work. Therefore, this construction can be carried out as a renovation project for existing buildings.

[0092] By constructing the wall 1 using blocks 5 to 7 and 9 to 12 made of wood material, finishing is not required and the wall 1 can be obtained by making the most of the texture of the wood.

[0093] The blocks 5 to 7 and 9 to 12 may be small pieces of wood, that is, scrap wood, which is the raw material, and therefore contribute to the effective use of wood resources.

[0094] Of course, the blocks 5 to 7 and 9 to 12 made of wood may be provided with a fire-resistant coating or have a fire-resistant finish.

[0095] Blocks 5-7, 9-12 are bonded together with adhesive, and the strength of the adhesive-soaked bonding surfaces is increased. As a result, it can be said that each bonding surface of blocks 5-7, 9-12 is reinforced, and as a wall 1, deformation such as buckling or crushing in the out-of-plane direction can be suppressed.

[0096] At least two walls 1 are constructed inside the opening 4 in the width direction of the columns 2 and beams 3, and since the orientation of the fibers f of the wood material differs between adjacent walls 1, even if there are strong axes and weak axes depending on the orientation of the fibers f of the wood material, walls 1 of the required strength can be constructed in a single opening 4.

[0097] At least two openings 4 are formed adjacent to each other, and a wall 1 is constructed inside each of the adjacent openings 4. Since the orientation of the fibers f of the wood material differs between these walls 1, even if there is a strong axis or a weak axis depending on the orientation of the fibers f of the wood material, the wall 1 of the required strength can be provided in the column-beam structure.

[0098] The octagonal blocks 5 are made of a polymeric material in which octagonal board pieces 5a of wood material with the fibers f oriented in the same direction are stacked and integrated in the width direction of the columns 2 and beams 3. Therefore, this polymeric material can be used to form octagonal blocks 5 that meet the required strength of the wall 1, and the wall 1 can be constructed.

[0099] In order to seal gaps between the hypotenuse w of the octagonal block 5 and the columns 2 or beams 3, and gaps between the columns 2 or beams 3 and the vertical sides y or horizontal sides x of the octagonal block 5 facing them, the hypotenuse w is glued to the columns 2 or beams 3, and the vertical sides y and horizontal sides x are glued to sealing blocks 9 to 12, which are sealing materials, and the sealing blocks 9 to 12 are glued to the columns 2 and beams 3, so that a solid wall 1 can be constructed against the columns 2 and beams 3.

[0100] Next, a second embodiment of a wall structure made of wood materials according to the present invention will be described. The explanations in Figures 1 to 4, 7 and 11 are the same as those in the first embodiment.

[0101] In the second embodiment, an octagonal block 5 shown in FIGS. 12 and 13 is used instead of the octagonal block 5 used in the first embodiment shown in FIGS.

[0102] The octagonal block 5 is formed of a polymeric material in which a plurality of octagonal plate pieces 5a are stacked and integrated in the width direction of the columns 2 and beams 3.

[0103] Of the inclined portions ws of the octagonal board pieces 5a that form the two pairs of hypotenuses w of the octagonal block 5, one set of inclined portions ws is formed parallel to the direction of the fibers f of the wood material, and the other set of inclined portions ws of the octagonal board pieces 5a is formed so as to intersect with the direction of the fibers f of the wood material, so that the directions of the fibers f of the wood material of these octagonal board pieces 5a that are adjacent in the width direction of the column 2 and beam 3 intersect with each other, for example, alternately.

[0104] Specifically, the octagonal block 5 can be formed in various ways as shown in the side views of FIG.

[0105] Figure 13(a) is a side view of the case where the raw material, cylindrical logs, etc., are cut in the direction of the fibers to form octagonal board pieces 5a, and two of these octagonal board pieces 5a are stacked and integrated in the width direction of the pillar 2 and beam 3 so that the fibers f of the wood material are oriented in a crosswise direction.

[0106] FIG. 13(b) is a side view of the case where, compared to FIG. 6(a), the number of octagonal plate pieces 5a is increased and the directions of the fibers f are alternated to cross, overlap and integrate them.

[0107] Figure 13(c) is a side view of a composite material in which thin plates are created from raw material logs, such as cylindrical logs, using a peeling method, and multiple octagonal plate pieces 5a cut from these thin plates are stacked and integrated together.

[0108] In this case as well, the wood materials are overlapped in the width direction of the pillars 2 and the beams 3 so that the directions of the fibers f of the wood materials cross each other.

[0109] Therefore, in the second embodiment, by arranging and gluing multiple octagonal blocks 5 inside the opening 4 in the vertical and horizontal directions with their equal-length hypotenuses w facing each other, a wall 1 is constructed in the single opening 4, as shown in Figure 11, in which the strong axis direction SA intersects (and the weak axis direction WA also intersects), and a column-beam structure is obtained that can provide equal resistance to both right-directed external forces RF and left-directed external forces LF.

[0110] In the second embodiment of the wooden wall structure, the octagonal blocks 5 are composite materials formed by stacking and integrating multiple octagonal boards 5a across the width of the columns 2 and beams 3. Of the inclined portions ws of the octagonal boards 5a, which form pairs of hypotenuses w of the octagonal blocks 5, one set of inclined portions ws is formed parallel to the direction of the fibers f of the wood material, and the other set of inclined portions ws of the octagonal boards 5a is formed crosswise to the direction of the fibers f of the wood material, so that the directions of the fibers f of the wood material of the octagonal boards 5a adjacent across the width of the columns 2 and beams 3 are crossed. The multiple octagonal blocks 5 are arranged vertically and horizontally inside the opening 4 with their equal-length hypotenuses w facing each other. This allows for the construction of a column-beam frame that can withstand both left and right forces by simply arranging the octagonal blocks 5 to construct a single wall 1.

[0111] It goes without saying that the second embodiment as described above also provides the same effects as the first embodiment.

[0112] The octagonal block 5 described above may have a regular octagonal shape, a shape in which the vertical side y and the horizontal side x have different lengths, or another shape. Figure 14 shows another modified example of the octagonal block 5.

[0113] A commonly used composite wood material is made by stacking and integrating multiple octagonal board pieces 5a so that their fibers f are oriented alternately and perpendicularly. As shown in Figures 14(a) and (b), in a composite wood (octagonal block 5) of octagonal board pieces 5a in which all interior angles are 135°, if one pair of hypotenuses w is parallel to the fibers f, the other pair of hypotenuses w will intersect at right angles with the orientation of the fibers f. Figure 14(a) shows the case where the lengths of the vertical side y and horizontal side x are less than the hypotenuse w, and Figure 14(b) shows the case where the lengths of the vertical side y and horizontal side x are less than the horizontal side x.

[0114] The hypotenuse w of the regular octagonal block 5 forms an angle of 45° (internal angle of 135°) with the vertical side y and the horizontal side x (see Figure 2), but Figure 14(c) shows a case where the hypotenuse w forms an angle of 60° with the vertical side y and 30° with the horizontal side x, and the length of the hypotenuse w is longer than the lengths of the vertical side y and the horizontal side x.

[0115] Figure 14(d) shows a case where two pairs of parallel, equal-length hypotenuses w are formed such that one pair of hypotenuses w forms an angle of 60° with respect to the vertical side y and 30° with respect to the horizontal side x, and the other pair of hypotenuses w forms an angle of 30° with respect to the vertical side y and 60° with respect to the horizontal side x.

[0116] In this way, if the octagonal block 5 has a hypotenuse w whose sum of the angles it makes with the vertical side y and the horizontal side x is 90°, it is of course possible to construct the wall 1 by applying this without being limited to the angles of 45°, 30°, or 60° mentioned above.

[0117] In the configurations illustrated in Figures 14(a), (c), and (d), the length of the oblique side w, which is the bonding point, is considerably longer than the vertical side y and the horizontal side x, so that the strength of the wall 1 obtained by bonding with an adhesive can be increased.
