Description

[Technical Field]

[0001] The technology disclosed in this specification relates to buildings. [Background technology]

[0002] Patent Document 1 discloses the structure of the corners on the periphery of a hipped roof. Patent Document 2 discloses a hipped roof. Patent Document 3 discloses a truss for a hipped roof or a square roof. Patent Document 4 discloses a hipped roof.

[0003] The hipped roofs or square roofs disclosed in any of Patent Documents 1 to 4 are rectangular or square when viewed from above, and the downward slope of one of the two sloped roofs on either side of the corner ridge is perpendicular to the downward slope of the other sloped roof. The outer wall of a building equipped with such a hipped roof or square roof is rectangular or square when viewed from above, and the corner ridge slopes downward from the top of the inside of the outer wall toward the corner of the outer wall. The eaves of one sloped roof are parallel to one of the exterior walls surrounding the corner, and the eaves of the other sloped roof are parallel to the other exterior wall.

[0004] When the design of the building's outer walls is changed to an octagonal shape when viewed from above, the corners of the outer walls become obtuse angles rather than right angles, so the structure that stably supports the hipped roof or square roof also needs to be redesigned accordingly.

[0006] The problem that the technology disclosed in this specification aims to solve is to stably support a first sloped roof and a second sloped roof that slope downward in a first direction and a second direction that are perpendicular to each other. [Means for solving the problem]

[0007] In order to solve the above problems, a method for constructing a building includes a first exterior wall facing a first direction, a second exterior wall facing a second direction perpendicular to the first direction, a third exterior wall facing a third direction oblique to the first direction and the second direction and adjacent to the first exterior wall and the second exterior wall between the first exterior wall and the second exterior wall, a spring beam that is placed on an upper end of the first exterior wall and joined to an upper end of the first exterior wall, extends in the second direction, and springs out from an end of the first exterior wall in the second direction, a cross member that extends in the first direction from an upper part of a corner between the second exterior wall and the third exterior wall and is joined at a right angle to an end of the spring beam, and a cross member that is placed on the third exterior wall and joined to an inner side of the third exterior wall and joined to an end of the spring beam at a right angle to the end of the spring beam. A building is provided which comprises: a corner ridge that slopes downward in the third direction to the outside of the wall and protrudes outward from the third exterior wall; a first sloping roof that is supported on the spring beam, slopes downward in the first direction from the inside of the first exterior wall to the outside of the first exterior wall, and protrudes outward from the first exterior wall; and a second sloping roof that is supported on the cross member, slopes downward in the second direction from the inside of the second exterior wall to the outside of the second exterior wall, and protrudes outward from the second exterior wall, adjacent to the first sloping roof with the corner ridge sandwiched between it and the first sloping roof. [Effects of the Invention]

[0008] Because the angle between the third exterior wall and the first exterior wall is an obtuse angle, and the angle between the third exterior wall and the second exterior wall is also an obtuse angle, even if the corner ridge protrudes outward from the third exterior wall by a long distance, the first sloping roof and the second sloping roof are each stably supported on the outside of the third exterior wall by the protruding beams and cross members joined at right angles.

[0018] According to [4], the first sloped roof (21) is stably supported by the cantilever beams (31) and the first spacers (51) on them. The second sloped roof (23) is stably supported by the cross members (43) and the second spacers (53) on them.

[0019] [5] The building (1) of [1] is provided with a second spring beam (33) that rests on the upper end of the second exterior wall (13), is joined to the upper end of the second exterior wall (13), extends in the first direction, springs out from the end of the second exterior wall (13) in the direction opposite to the first direction, and is butt-joined to the cross member (43) at the upper part of the corner between the second exterior wall (13) and the third exterior wall (12).

[0020] According to [5], even if the cross member (43) is short, the cross member (43) is firmly connected to the second exterior wall (13) through the second spring beam (33), so that the first sloped roof (21) and the second sloped roof (23) are stably supported outside the third exterior wall (12).

[0021] [6] The building (1) of [5] is provided with a first spacer (51) joined onto the upper end of the spring beam (31) and having an upper surface sloping downward in the first direction, and a second spacer (53) joined onto the upper ends of the cross member (43) and the second spring beam (33) and having an upper surface sloping downward in the second direction, wherein the first sloped roof (21) rests on the upper surface of the first spacer (51) and is joined to the first spacer (51), the slope of the first sloped roof (21) is determined by the upper surface of the first spacer (51), the second sloped roof (23) rests on the upper surface of the second spacer (53) and is joined to the second spacer (53), the slope of the second sloped roof (23) is determined by the upper surface of the second spacer (53).

[0026] [9] In the building (1) of [8], the horizontal member (43) is supported from below by the adjustment members (121 to 126).

[0027] According to [9], since the cross member (43) is supported by the adjustment members (121-126) below it, the first sloped roof (21) and the second sloped roof (23) are stably supported on the outside of the third outer wall (12).

[0028] The features, objects and advantages of the above-listed building will become apparent from the drawings showing preferred embodiments and the accompanying description of the drawings.

[0029] [Embodiment] Hereinafter, embodiments will be described with reference to the drawings. Features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. Because the drawings are provided for illustrative purposes only, the scope of the present invention is not limited to the examples in the drawings.

[0030] 1 and 2 are perspective views of a building 1. In Fig. 2, a rectangular roof 20 of the building 1 is shown in phantom lines, and the bottom of the rectangular roof 20 is also shown.

[0031] Building 1 may be one-story or multiple-story. If building 1 is one-story, Figures 1 and 2 show the first floor of building 1. If building 1 is multiple-story, Figures 1 and 2 show the top floor of building 1. Whether building 1 is one-story or multiple-story, the parts shown in Figures 1 and 2 are made of wood. Whether building 1 is one-story or multiple-story, the parts shown in Figures 1 and 2 are constructed on the substructure of building 1. If building 1 is one-story, the substructure of building 1 refers to the foundation or basement of building 1. If building 1 is multiple-story, the substructure of building 1 refers to the part from the foundation or basement of building 1 to one floor below the top floor.

[0032] Whether Building 1 is one-story or multi-story, the foundation or basement of Building 1 is made of reinforced concrete. If Building 1 is multi-story, the ground floors other than the top floor are made of wood, reinforced concrete, or a mixed construction. A mixed construction means that the lower part is made of reinforced concrete and the upper part is made of wood.

[0033] The energy used from the production to the disposal and disposal of wood is less than the energy used from the production to the disposal and disposal of metal or concrete materials. The use of wood construction in Building 1 contributes to the realization of a carbon-neutral society by reducing carbon dioxide emissions to virtually zero, and to the achievement of the Sustainable Development Goals (SDGs).

[0034] The wooden portion of the building 1 is a wall structure, a frame structure, or a combination of a wall structure and a frame structure. However, the portion shown in Figures 1 and 2 is a wall structure, and in particular, a wall structure built using a panel construction method such as a wood panel adhesive construction method.

[0035] A wall structure refers to a structure in which the load and seismic force of the building 1 and its cargo are supported by walls. A frame structure refers to a structure in which the load and seismic force of the building 1 and its cargo are supported by columns, beams, and braces. The wooden portion of the building 1 may be constructed using panel construction, frame-and-beam panel construction, or frame-and-wall construction, or a combination of two or more of these. In one example, the wooden portion of the building 1 is a wall structure constructed using panel construction, particularly wood panel adhesive construction. Wood panels used in wood panel adhesive construction include triangular panels and rectangular panels. A rectangular panel has a rectangular frame formed by assembling four wooden frames into a rectangular frame shape and wooden face panels attached to both or one side of the rectangular frame. A rectangular panel may have one or more auxiliary beams attached to the inside of the rectangular frame. Rectangular panels are used as roof panels or wall panels. The triangular panel has a triangular frame formed by assembling three wooden frames into a right-angled isosceles triangle, and a wooden face member attached to one or both sides of the triangular frame. The triangular panel may have one or more auxiliary beams attached to the inside of the triangular frame. The triangular panel is used as a roof panel.

[0036] The building 1 has an outer perimeter wall 10 and a rectangular roof 20. When viewed from above, the outer perimeter wall 10 forms an equiangular octagon. The rectangular roof 20 is constructed on the top end of the outer perimeter wall 10. The rectangular roof 20 covers the interior space enclosed by the outer perimeter wall 10 from above.

[0037] The outer perimeter wall 10 includes exterior wall 11, exterior wall 12, exterior wall 13, exterior wall 14, exterior wall 15, exterior wall 16, exterior wall 17, and exterior wall 18. Exterior wall 11 faces south, exterior wall 12 faces southwest, exterior wall 13 faces west, exterior wall 14 faces northwest, exterior wall 15 faces north, exterior wall 16 faces northeast, exterior wall 17 faces east, and exterior wall 18 faces southeast. Exterior wall 12 is adjacent to exterior walls 11 and 13 between exterior walls 11 and 13, exterior wall 14 is adjacent to exterior walls 13 and 15 between exterior walls 13 and 15, exterior wall 16 is adjacent to exterior walls 15 and 17 between exterior walls 15 and 17, and exterior wall 18 is adjacent to exterior walls 17 and 18 between exterior walls 17 and 18.

[0038] The exterior walls 11, 13, 15, and 17 have the same width, and the exterior walls 12, 14, 16, and 18 have the same width. The widths of the exterior walls 12, 14, 16, and 18 are shorter than the widths of the exterior walls 11, 13, 15, and 17. The orientation of the exterior walls 11 to 18 is an example, and the orientation of the exterior walls 11 to 18 may be changed. If the building 1 is one-story, the exterior walls 11 to 18 are the exterior walls of the first floor. If the building 1 is multiple-story, the exterior walls 11 to 18 are the exterior walls of the top floor. An opening may be formed in at least one of the exterior walls 11 to 18, and a fixture may be installed in the opening.

[0039] The exterior walls 11-18 each have multiple wall panels, and wooden adjustment members as needed. These wall panels are arranged along vertical planes, and adjustment members are arranged between adjacent wall panels as needed, and adjacent wall panels and adjustment members are joined with adhesive to form the exterior walls 11-18. Wall panels of various sizes are prepared, and the wall panels have standardized sizes. If the arrangement of multiple wall panels alone does not fit the size of the exterior walls 11-18, adjustment members are used to fill in the gaps. Adjustment members are column-shaped construction structural materials with square or rectangular cross sections.

[0040] For example, as shown in Figure 4, wall panels 11a to 11d are arranged on the south exterior wall 11. A lintel 11e and jambs 11f and 11g frame the opening enclosed by the wall panels 11b to 11d. Three mullions 11h are provided in the opening, which divides the opening into four areas. Fittings, particularly window sashes, are attached to these four areas.

[0041] For example, as shown in Figure 5, wall panels 12a to 12e are arranged on the southwest exterior wall 12. Adjusting member 12g is arranged between wall panel 12b and wall panel 12d and between wall panel 12c and wall panel 12d. Adjusting member 12h is arranged between wall panel 12d and wall panel 12e. Adjusting member 12i is arranged between wall panel 12e and wall panel 12d. Vertical frames 12j and 12k frame the opening surrounded by wall panels 12a to 12c and adjusting member 2g.

[0042] For example, as shown in FIG. 6, wall panels 13a to 13gg are allocated to the western exterior wall 13.

[0043] In the above description, the exterior walls 11 to 18 are bearing walls assembled by the wood panel adhesive construction method. However, the exterior walls 11 to 18 may also be bearing walls assembled by the wood frame construction method.

[0044] As shown in Figure 7, the angle between the south exterior wall 11 and the southwest exterior wall 12 is 135°. A 90° angle can be formed by butt-jointing wall panels, but a 135° angle cannot. Therefore, triangular prism-shaped adjustment members 111 and 112 with a right-angled isosceles triangle cross section are allocated to fill the gap between the south exterior wall 11 and the southwest exterior wall 12, thereby forming a 135° angle between the south exterior wall 11 and the southwest exterior wall 12. Specifically, the surface of the adjustment member 111 forming one of the isosceles sides of the right triangle is joined to the western end of the south exterior wall 11 via the prismatic adjustment members 113-106, and the surface of the adjustment member 111 forming the other side is joined to the surface of the adjustment member 112 forming the hypotenuse of the isosceles side of the right triangle. The surface of adjusting material 111 forming the hypotenuse of the right triangle is flush with the outdoor surface of southwest exterior wall 12 and forms an angle of 135° with the outdoor surface of exterior wall 11. The surface of adjusting material 112 forming one of the isosceles sides of the right triangle is joined to the southeast end of southwest exterior wall 12. The surface of adjusting material 112 forming the other side is flush with the indoor surface of exterior wall 12 and forms an angle of 135° with the indoor surface of exterior wall 11. Adjusting materials 113 to 115 fit into the inside corner between the surface of adjusting material 112 forming the hypotenuse and the equilateral sides of adjusting material 111 forming the equilateral sides.

[0045] As shown in FIG. 8 , the angle between the southwest exterior wall 12 and the west exterior wall 13 is 135°. Triangular prism-shaped adjustment members 121 and 122, each having a cross section of an isosceles right triangle, are arranged to fill the space between the southwest exterior wall 12 and the west exterior wall 13, thereby forming a 135° angle between the southwest exterior wall 12 and the west exterior wall 13. Specifically, the surface of adjustment member 121 forming one of the isosceles sides of the right triangle is joined to the southern end of the west exterior wall 13 via prismatic adjustment members 123 to 126, and the surface of adjustment member 121 forming the other side is joined to the surface of adjustment member 122 forming the hypotenuse of the isosceles of the right triangle. The surface of adjustment member 121 forming the hypotenuse of the right triangle is flush with the outdoor surface of southwest exterior wall 12 and forms an angle of 135° with the outdoor surface of exterior wall 13. The surface of adjustment material 122 forming one of the isosceles sides of the right triangle is joined to the northwest end of southwest exterior wall 12. The surface of adjustment material 122 forming the other side is flush with the indoor surface of exterior wall 12 and forms an angle of 135° with the indoor surface of exterior wall 13. Adjustment materials 123 to 125 fit into the inside corner between the surface of adjustment material 122 forming the hypotenuse and the equilateral sides of adjustment material 121.

[0046] Two right-angled isosceles triangular prism adjustment members and four rectangular prism adjustment members are provided at the corners between the south exterior wall 11 and the southwest exterior wall 12 and between the southwest exterior wall 12 and the west exterior wall 13, as well as at the corners between exterior wall 13 and exterior wall 14, between exterior wall 14 and exterior wall 15, between exterior wall 15 and exterior wall 16, between exterior wall 16 and exterior wall 17, between exterior wall 17 and exterior wall 18, and between exterior wall 18 and exterior wall 11.

[0047] As shown in FIG. 2, an interior wall 200 is installed inside the outer peripheral wall 10. The interior wall 200 is installed in an upright position midway between the south exterior wall 11 and the north exterior wall 15. The interior wall 200 is installed parallel to the exterior walls 11 and 15. The interior wall 200 has a plurality of wall panels and, if necessary, wooden adjustment members. These wall panels are arranged along vertical planes, and if necessary, adjustment members are arranged between adjacent wall panels, and adjacent pieces of these wall panels and adjustment members are joined together with an adhesive to form the interior wall 200.

[0048] As shown in Figure 1, square roof 20 has a groove 29, a south-sloped roof 21, a west-sloped roof 23, a north-sloped roof 25, an east-sloped roof 27, a southwest corner ridge 22, a northwest corner ridge 24, a northeast corner ridge 26, and a southeast corner ridge 28. Groove 29 is the peak of square roof 20. Groove 29 is located directly above the center of the equiangular octagon formed by outer perimeter wall 10. South-sloped roof 21 slopes southward from groove 29 to the outside of exterior wall 11, west-sloped roof 23 slopes westward from groove 29 to the outside of exterior wall 13, north-sloped roof 25 slopes northward from groove 29 to the outside of exterior wall 15, and east-sloped roof 27 slopes eastward from groove 29 to the outside of exterior wall 17.

[0049] The southwest corner ridge 22 is located at the boundary between the south-sloped roof 21 and the west-sloped roof 23, and the south-sloped roof 21 and the west-sloped roof 23 are adjacent to each other with the southwest corner ridge 22 between them. The southwest corner ridge 22 slopes downward to the southwest from the gap 29 to the outside of the exterior wall 13. The southwest corner ridge 22 protrudes outward from the exterior wall 13.

[0050] Similarly, the west-sloped roof 23 and the north-sloped roof 25 are adjacent with a northwest corner ridge 24 between them, the north-sloped roof 25 and the east-sloped roof 27 are adjacent with a northeast corner ridge 26 between them, and the east-sloped roof 27 and the south-sloped roof 21 are adjacent with a southeast corner ridge 28 between them.

[0051] The rectangular roof 20 has eaves extending in the east, west, north, and south directions. That is, the south-sloped roof 21 extends south from the south exterior wall 11, the west-sloped roof 23 extends west from the west exterior wall 13, the north-sloped roof 25 extends north from the north exterior wall 15, and the east-sloped roof 27 extends east from the east exterior wall 17. The southwest corner ridge 22 extends southwest from the southwest exterior wall 12, the northwest corner ridge 24 extends northwest from the northwest exterior wall 14, the northeast corner ridge 26 extends northeast from the northeast exterior wall 16, and the southeast corner ridge 28 extends northwest from the southeast exterior wall 18. The eaves of the south-sloped roof 21 are parallel to the south exterior wall 11, the eaves of the west-sloped roof 23 are parallel to the west exterior wall 13, the eaves of the north-sloped roof 25 are parallel to the south exterior wall 15, and the eaves of the east-sloped roof 27 are parallel to the east exterior wall 17.

[0052] Fig. 9 is a plan view of a square roof 20. As shown in Fig. 9, the square roof 20 is a roof assembled by a wood panel adhesive construction method.

[0053] The south-sloped roof 21 has multiple rectangular roof panels 211, multiple rectangular roof panels 212, and multiple right-angled isosceles triangular roof panels 213, 214, 215, 216, and 217. These roof panels 211-217 are arranged along a south-sloping surface so that they slope downward to the south, and adjacent roof panels 211-217 are joined together with adhesive to form the south-sloped roof 21. Roof panel 213 is located at the southwest end of the south-sloped roof 21, with its hypotenuse aligned along the southwest corner ridge 22 and one equilateral side aligned along the eaves of the south-sloped roof 21. Roof panel 214 is located at the southeast end of the south-sloped roof 21, with its hypotenuse aligned along the southeast corner ridge 28 and one equilateral side aligned along the eaves of the south-sloped roof 21. The roof panels are arranged along the eaves of the south-sloping roof 21 between roof panel 213 and roof panel 214. Roof panel 215 is positioned offset from roof panel 213 toward the groove 29, with the hypotenuse of roof panel 213 positioned along the southwest corner ridge 22. Roof panel 216 is positioned offset from roof panel 214 toward the groove 29, with the hypotenuse of roof panel 216 positioned along the southeast corner ridge 28. Roof panel 212 is adjacent to the roof panel on the groove 29 side. Roof panel 212 is arranged between roof panel 215 and roof panel 216 along the short side of roof panel 215. The right angle of roof panel 217 is positioned at the groove 29, with the two equal sides of roof panel 217 positioned along the corners 22 and 28, respectively.

[0054] The layout of roof panels 231-237 of the west-sloped roof 23 is the same as the layout of roof panels 211-217 of the south-sloped roof 21. Roof panels 231, 232, 233, 234, 235, 236, and 237 of the west-sloped roof 23 correspond to roof panels 211, 212, 213, 214, 215, 216, and 217 of the south-sloped roof 21, respectively. Roof panels 234, 236, and 237 of the west-sloped roof 23 are arranged along the southwest corner ridge 22, with roof panel 234 located at the southwest end of the west-sloped roof 23, the right angle of roof panel 237 being arranged at intersection 29, and roof panel 216 being arranged between roof panel 234 and roof panel 237. The layout of the roof panels of the north-sloped roof 25 and the east-sloped roof 27 is the same as the layout of the roof panels 211 to 217 of the south-sloped roof 21.

[0055] The equal sides of roof panel 237 and the equal sides of roof panel 217 form a valley between them, and a corner ridge member is embedded in the valley. The hypotenuse of roof panel 236 and the hypotenuse of roof panel 215 form a valley between them, and a corner ridge member is embedded in the valley. The hypotenuse of roof panel 234 and the hypotenuse of roof panel 213 form a valley between them, and a corner ridge member is embedded in the valley. These corner ridge members form the southwest corner ridge 22. The same applies to the northwest corner ridge 24, the northeast corner ridge 26, and the southeast corner ridge 28.

[0056] The roof panels 213 and 234 form the southwest corner of the rectangular roof 20. A southwest corner ridge 22 projects southwest from the southwest exterior wall 12, and the southwest corner of the rectangular roof 20, i.e., the roof panels 213 and 234, project southwest from the southwest exterior wall 12.

[0057] Next, the truss structure that supports the rectangular roof 20 described above will be explained.

[0058] As shown in Figure 2, a truss beam 209 is installed upright on the center of the upper edge of the interior wall 200. Triangular truss panel assemblies 203 and 207 are installed upright on the center of the upper edge of the interior wall 200 on both sides of the truss beam 209. The truss panel assembly 203 includes multiple truss panels and, if necessary, wooden adjustment members. The truss panels used in the truss panel assembly 203 include triangular and rectangular truss panels. These truss panels are wood panels. The truss panels are arranged along a vertical plane, and if necessary, adjustment members are arranged between adjacent truss panels. Adjacent truss panels and adjustment members are joined with adhesive to form the truss panel assembly 203. The same is true for the truss panel assembly 207. The truss panel assembly 203 has a downward sloping surface on its top surface that slopes westward from the top of the truss beam 209. The roof truss panel assembly 207 has on its upper surface a downward sloping surface eastward from the top of the main beam 209.

[0059] As shown in FIG. 9 , truss panel assemblies 201 and 205, which are similar to truss panel assemblies 203 and 207, are installed perpendicular to the truss panel assemblies 203 and 207 at the rafters 209. The truss panel assembly 201 has a sloped surface on its upper surface that slopes downward from the top of the rafters 209 to the south. The truss panel assembly 205 has a sloped surface on its upper surface that slopes downward from the top of the rafters 209 to the north. Similar to the truss panel assemblies 203 and 207, the truss panel assemblies 201 and 205 may be installed on an interior wall. However, unlike the truss panel assemblies 203 and 207, the truss panel assemblies 201 and 205 may be installed on multiple columns or beams. Furthermore, rafters may be used instead of the truss panel assemblies 201 and 205.

[0060] As shown in Figures 4 and 9, a cantilever beam 31 rests on the upper end of the south exterior wall 11 and is joined to the upper end of the exterior wall 11. The cantilever beam 31 extends east-west from the east end to the west end of the south exterior wall 11, and further protrudes from the west end of the exterior wall 11 to the west. The cantilever beam 31 rests on the upper ends of the adjustment members 111-116 between the south exterior wall 11 and the southwest exterior wall 12 and is joined to the upper ends of the adjustment members 111-116.

[0061] Similarly, cantilever beams 33, 35, and 37 are joined to the upper ends of exterior walls 13, 15, and 17, respectively. Cantilever beam 33 extends north-south from the south end to the north end of western exterior wall 13, and further protrudes north from the north end of exterior wall 13. Cantilever beam 35 extends east-west from the west end to the east end of northern exterior wall 15, and further protrudes east from the east end of exterior wall 13. Cantilever beam 37 extends north-south from the north end to the south end of eastern exterior wall 17, and further protrudes south from the south end of exterior wall 17.

[0062] As shown in Figures 6 and 9, the cross member 43 is butt-joined to the south end of the cantilever beam 33 on top of the adjustment members 121-126. The vertical dimension of the cross member 43, i.e., the beam depth, is shorter than the beam depth of the cantilever beam 33. The cross member 43 rests on top of the adjustment members 121-126 and is joined to the upper end of the adjustment member 1213. The cross member 43 is supported from below by the adjustment members 121-126. The cross member 43 extends south from above the adjustment members 121-126. The south end of the cross member 43 butts against the side of the cantilever beam 33 and is joined to the cantilever beam 33, so that the cross member 43 and the cantilever beam 33 form a right angle. The cross member 43 and the cantilever beam 33 may be joined using metal fittings, screws, or adhesive.

[0063] Similarly, the eastern end of cross member 45 is butt-joined to the western end of cantilever beam 33 on the adjustment member, the western end of cross member 45 is joined to the side of cantilever beam 33, the southern end of cross member 47 is butt-joined to the northern end of cantilever beam 37 on the adjustment member, the northern end of cross member 47 is joined to the side of cantilever beam 35, the western end of cross member 41 is butt-joined to the eastern end of cantilever beam 31 on the adjustment member, and the eastern end of cross member 41 is joined to the side of cantilever beam 37. Therefore, these cantilever beams 31, 33, 35, 37 and cross members 41, 43, 45, 47 are assembled into a square frame shape.

[0064] As shown in Figure 4, spacers 51 rest on the upper ends of the cantilever beams 31 and cross members 41 and are joined to the upper ends of the cantilever beams 31 and cross members 41. The spacers 51 extend from the western end of the cantilever beams 31 to the eastern end of the cross member 41. The eastern end of the spacer 51 extends beyond the eastern end of the cross member 41 and rests on the southern end of the cantilever beam 37, and is joined to the upper end of the cantilever beam 37. The upper surface of the spacer 51 slopes downward to the south. The south-sloped roof 21 is supported on the cantilever beams 31, cross members 41, and spacers 51. The slope of the south-sloped roof 21 is determined by the upper surfaces of the spacers 51.

[0065] As shown in FIG. 6, a spacer 53 rests on the upper ends of the cantilever beam 33 and the cross member 43 and is joined to the upper ends of the cantilever beam 33 and the cross member 43. The spacer 53 extends from the western end of the cantilever beam 33 to the eastern end of the cross member 41. The southern end of the spacer 53 extends beyond the southern end of the cross member 43 and rests on the western end of the cantilever beam 31, and is joined to the upper end of the cantilever beam 31. The southern end of the spacer 53 is mitered to the western end of the spacer 51. The upper surface of the spacer 53 slopes downward to the west. The west-sloped roof 23 is supported on the cantilever beam 33, the cross member 43, and the spacer 53. The slope of the west-sloped roof 23 is determined by the upper surface of the spacer 53.

[0066] The south-sloped roof 21, the west-sloped roof 23 and the southwest corner ridge 22 protrude outward from the corner formed by the cantilever beam 31 and the cross member 43.

[0067] As shown in Figure 5, adjustment members 32, 42 are placed on top of the upper end of the southwest exterior wall 12 and joined to the wall 12. The adjustment members 32, 42 are provided to extend the wall 12 upward, and the upper ends of the adjustment members 32, 42 are aligned with the upper ends of the cantilever beam 31 and the cross member 41. The adjustment member 32 is spaced away from the adjustment member 42 toward the cantilever beam 31, and the adjustment member 42 is spaced away from the adjustment member 32 toward the cross member 43. The northwest exterior wall 14, the northeast exterior wall 16, and the southeast exterior wall 17 are also extended upward by two adjustment members.

[0068] Figure 11 is an enlarged view of region XI shown in Figure 10. Figure 12 is an end view along the XII-XII cross section shown in Figure 11. As shown in Figures 3, 11, and 12, a beam 311 and an adjustment member 312 are installed between the southwest exterior wall 12 and the interior wall 220. One end of the beam 311 is placed on the southwest exterior wall 12 between the adjustment members 32 and 42 and joined to the wall 12. The other end of the beam 311 is placed on the upper end of the interior wall 200 and joined to the interior wall 200 and to the roof truss panel assembly 203. An adjustment member 312 is installed on the beam 311. Three adjustment members 313 in the shape of isosceles triangular prisms are placed on the upper end of the southwest exterior wall 12 and filled in the gaps between the beam 311 and the adjustment members 32 and 42. The above description of the configuration of the upper end of the exterior wall 12 using Figures 3, 11 and 12 also applies to the upper ends of the northwest exterior wall 14, northeast exterior wall 16 and southeast exterior wall 17.

[0069] FIG. 13 is a front view of the roof panel 410, which includes two roof panel 413 and 414. FIG. 14 is a side view of the roof panel 414. As shown in FIGS. 3, 13, and 14, the two roof panel 413 and 414 are joined to the southwest exterior wall 12, more specifically, to the upper ends of the adjustment members 32 and 42. The roof panel 413 and 414 are right-angled triangular wooden panels. The shortest side of the roof panel 413 abuts against the shortest side of the roof panel 414, and these sides are joined to each other with an adhesive or the like. The second shortest sides of the roof panel 413 and 414 abut against the upper ends of the adjustment members 32 and 42, and the second shortest sides of the roof panel 413 and 414 are joined to the upper ends of the adjustment members 32 and 42 with an adhesive or the like.

[0070] The roof sill panels 413, 414 are installed to extend the southwest exterior wall 12 and adjustment members 32, 42 upward, and the combination of the roof sill panels 413, 414 forms an isosceles triangle. Therefore, the combination of the roof sill panels 413, 414 constitutes a roof sill installed on the southwest exterior wall 12. The southwest corner ridge 22 slopes downward to the southwest from the inside of the roof sill to the outside of the roof sill above the combination of the roof sill panels 413, 414, i.e., the top of the roof sill. The southwest corner ridge 22 protrudes outward from the combination of the roof sill panels 413, 414.

[0071] A spacer 423 rests on the hypotenuse of the roof panel 413 and is joined to the hypotenuse of the roof panel 413. The spacer 423 extends from one end of the hypotenuse of the roof panel 413 to the other. The upper surface of the spacer 423 slopes downward to the south. The south-sloped roof 21 is supported on the roof panel 413 and the spacer 423. The slope of the south-sloped roof 21 is determined by the upper surface of the spacer 423.

[0072] A spacer 424 rests on the hypotenuse of the roofing panel 414 and is joined to the hypotenuse of the roofing panel 414. The spacer 424 extends from one end of the hypotenuse of the roofing panel 413 to the other. The upper surface of the spacer 424 slopes downward to the west. The west-sloped roof 23 is supported on the roofing panel 414 and the spacer 424. The slope of the west-sloped roof 23 is determined by the upper surface of the spacer 424.

[0073] Roof trim similar to roof trim 410 is provided on the northwest exterior wall 14, the northeast exterior wall 16, and the southeast exterior wall 17. As with the southern portion of the west-sloped roof 23, the slope of the northern portion of the west-sloped roof 23 is provided by a spacer on one equal side of the northwest roof trim, the slope of the western portion of the north-sloped roof 25 is provided by a spacer on the other equal side of the northwest roof trim, the slope of the eastern portion of the north-sloped roof 25 is provided by a spacer on one equal side of the northeast roof trim, the slope of the northern portion of the east-sloped roof 27 is provided by a spacer on the other equal side of the northeast roof trim, the slope of the southern portion of the east-sloped roof 27 is provided by a spacer on one hypotenuse of the southeast roof trim, and the slope of the eastern portion of the south-sloped roof 21 is provided by a spacer on the other hypotenuse of the southeast roof trim.

[0074] As shown in Figures 3, 9 and 10, roof panels 211 and 213 rest on the upper surface of spacer 51 and are joined to spacer 51 and beam 31 with adhesive, screws, or both. Roof panels 211, 213, and 214 extend south from beam 31. Roof panel 214 rests on the upper surface of spacer 51 and is joined to spacer 51 and beam 41 with adhesive, screws, or both. Roof panel 214 extends west from beam 41.

[0075] The roof panel 213 rests on the upper surface of the spacer 423 and is joined to the spacer 423 and the roof panel 413 with adhesive or screws, or both. The roof panel 213 is supported on the spacer 423 and the roof panel 413. The downward south slope of the roof panel 213 is provided by the spacer 51 and the upper surface of the spacer 423.

[0076] The roof panels 231 and 233 rest on the upper surface of the spacer 53 and are joined to the spacer 53 and the beam 33 with adhesive or screws, or both. The roof panels 231, 233, and 234 protrude to the west from the beam 33. The roof panel 234 rests on the upper surface of the spacer 53 and is joined to the spacer 53 and the cross member 43 with adhesive or screws, or both. The roof panel 234 protrudes to the west from the cross member 43.

[0077] The roof panel 234 rests on the upper surface of the spacer 424 and is joined to the spacer 424 and the roof panel 414 with adhesive or screws, or both. The roof panel 234 is supported on the spacer 424 and the roof panel 422. The downward slope of the roof panel 234 to the west is provided by the spacer 53 and the upper surface of the spacer 424.

[0078] Roof panel 213, roof panel 234 and southwest corner ridge 22 project outward from the angle formed by joist 33 and cross member 45.

[0079] As described above, in the same way that the slope of the roof panels 211, 234 forming the southwest corner of the rectangular roof 20 is achieved by the spacers 51, 423, 53, 424, the slope of the roof panels forming the northwest, northeast or southeast corner of the rectangular roof 20 is also achieved by spacers.

[0080] ==Summary== As shown in Figures 1 to 3, the southwest exterior wall 12 is located inside the intersection of the south exterior wall 11 and the west exterior wall 13, which are respectively extended west and south. The southwest corner ridge 22 slopes downward to the southwest on top of the southwest exterior wall 12 from the inside to the outside of the southwest exterior wall 12, so the southwest corner ridge 22 protrudes outward from the third exterior wall 12 by a long distance. A cantilever beam 31 protrudes west from the end of the south exterior wall 11, and a cross member 43 extends south from the top of the corner between the west exterior wall 13 and the southwest exterior wall 12. The cantilever beam 31 and the cross member 43 are joined at a right angle, so the cantilever beam 31 and the cross member 43 stably support the south-sloped roof 21 and the west-sloped roof 23 on the outside of the southwest exterior wall 12, respectively.

[0081] On the south side of building 1, spacer 51 rests on the upper end of cantilever beam 31 and is joined to it. Spacer 51 has an upper surface that slopes downward to the south. South-sloped roof 21 rests on the upper surface of spacer 51 and is joined to it, and the slope of south-sloped roof 21 is determined by the upper surface of spacer 53. Therefore, south-sloped roof 21 is stably supported by cantilever beam 31 and the spacer 51 above it. On the west side of building 1, west-sloped roof 23 is stably supported by cantilever beam 33 and the spacer 53 above it. On the north side of building 1, north-sloped roof 25 is stably supported by cantilever beam 35 and the spacer above it. On the damaged side of building 1, east-sloped roof 27 is stably supported by cantilever beam 37 and the spacer above it.

[0082] The ends of spacer 51 and spacer 53 are mitered together under southwest corner ridge 22, so that the gap under southwest corner ridge 22 is closed by the mitered joint.

[0083] Since the cross member 43 is supported by the adjustment members 121 to 126 below it, the south-sloped roof 21 and the west-sloped roof 23 are stably supported on the outside of the third exterior wall 12.

[0084] The south-sloped roof 21 on one side of the southwest corner building 22, particularly the roof panel 213, is supported on one equal side of the roof edge 410, and the west-sloped roof 23 on the other side of the southwest corner building 22, particularly the roof panel 234, is supported on the other equal side of the roof edge 410, thereby improving the stability of the roof panels 213 and 234.

[0085] Spacer 423 is attached to one equal side of roof edge 410. The first spacer has an upper surface that slopes downward to the south. The south-sloped roof 21, particularly roof panel 213, rests on the upper surface of spacer 423 and is attached to the spacer 423, and the slope of the south-sloped roof 21 is determined by the upper surface of spacer 423. Therefore, spacer 423 contributes to stably supporting the south-sloped roof 21 on one equal side of roof edge 410. Similarly, spacer 424 contributes to stably supporting the west-sloped roof 23 on the other equal side of roof edge 410.

[0086] Since the roof siding 410 is an assembly of the roof siding panels 413, 414, when constructing the building (1), the roof siding 410 can be separated into the roof siding panels 413, 414 and easily transported.

[0087] The large square frame provided on the outer peripheral wall 10 can also be separated into the beams 31, 33, 35, 37 and the cross members 41, 43, 45, 47 for easy transportation.

[0088] The above-disclosed embodiments have been made for the purposes of illustration and example only, and are not intended to limit the scope of the present invention, which should be interpreted by the terms of the claims. [Explanation of symbols]
