Description

[Technical field]

[0001] The present invention relates to a structure. [Background technology]

[0002] 2. Description of the Related Art There is known a structure that includes a primary structure made of reinforced concrete and a secondary structure made of wood that is supported by the primary structure (see, for example, Patent Document 1).

[0003] Also, a joint structure between a reinforced concrete column and a wooden beam is known (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 3-1991147979 [Patent Document 2] JP 2020-084593 A Summary of the Invention [Problem to be solved by the invention]

[0005] By the way, there is a known structure with a skeleton-infill structure. In this type of structure, the walls are generally infilled and the floors are skeletonized. Therefore, it is difficult to change the layout of the floors.

[0006] SUMMARY OF THE PRESENT EMBODIMENT In consideration of the above, an object of the present invention is to make it possible to easily change the layout of wall units and floor units. [Means for solving the problem]

[0007] The structure described in claim 1 comprises a wooden structure having a plurality of wooden frames formed by wooden columns and wooden beams, an adjacent structure having earthquake-resistant elements, adjacent to the wooden structure and joined to the wooden structure, a wall unit removably attached to the wooden structure, and a floor unit removably attached to the wooden structure.

[0008] According to the structure of claim 1, the wooden structure has a plurality of wooden frames formed by wooden columns and wooden beams. The wooden structure is adjacent to an adjacent structure. The adjacent structure has an earthquake-resistant element and is joined to the wooden structure.

[0009] Here, the wall units and floor units are detachably attached to the wooden structure. This makes it easy to change the layout of the wall units and floor units, and to add or remove them. Therefore, the present invention makes it easy to change the plan or use of the structure, and increases the freedom to change the plan or use.

[0010] On the other hand, wooden structures may lack earthquake resistance compared to reinforced concrete structures.

[0011] In contrast, in the present invention, an adjacent structure having earthquake-resistant elements is joined to a wooden structure, and the earthquake resistance of the wooden structure can be ensured by having the adjacent structure bear the earthquake force.

[0012] The structure described in claim 2 is the structure described in claim 1, in which the wall unit is supported by a wall bracket removably attached to the wooden beam by a wall mounting member that passes through a through hole formed in the wooden beam, and the floor unit is supported by a floor bracket removably attached to the wooden beam by a floor mounting member that passes through a through hole formed in the wooden beam.

[0013] According to the structure of claim 2, the wall unit is supported by a wall bracket. The wall bracket is detachably attached to the wooden beam by a wall mounting member that passes through a through hole formed in the wooden beam. The floor unit is supported by the floor bracket. The floor bracket is detachably attached to the wooden beam by a floor mounting member that passes through a through hole formed in the wooden beam.

[0014] Here, compared to reinforced concrete beams, through holes for passing wall mounting members or floor mounting members through are easier to form in wooden beams. Also, through holes can be easily formed in existing wooden beams. Therefore, in the present invention, wall brackets and floor brackets can be easily and detachably attached to wooden beams. This makes it easier to change the layout of wall units and floor units and to add or remove them.

[0015] The structure described in claim 3 is the structure described in claim 1 or 2, in which the plurality of wooden frames are assembled in a three-dimensional lattice shape.

[0016] According to the structure of claim 3, a plurality of wooden frames are assembled in a three-dimensional lattice shape. By attaching and detaching wall units and floor units to a plurality of wooden frames configured in this way in a three-dimensional lattice shape, the degree of freedom in the plan of the structure can be increased. Effect of the Invention

[0017] As described above, according to the present invention, the layout of the wall units and floor units can be easily changed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, one embodiment will be described with reference to the drawings.

[0020] (structure) A structure 10 according to this embodiment is shown in Fig. 1. Note that the arrow X direction and the arrow Y direction shown appropriately in each figure indicate two horizontal directions perpendicular to each other. Also, the arrow Z direction indicates the height direction (up-down direction) of the structure 10.

[0021] The structure (building) 10 has, for example, multiple floors (multiple stories). The structure 10 has a skeleton-infill structure. The structure 10 includes a foundation 12, a wooden structure 20 as the structure body, and an adjacent structure 40.

[0022] (Basic) The foundation 12 is, for example, a slab foundation (spread foundation). That is, the foundation 12 is a foundation slab made of reinforced concrete and is laid on the ground G. On the foundation 12, the wooden structure 20 and the adjacent structure 40 are erected.

[0023] The foundation 12 is not limited to a mat foundation, but may be a strip foundation, etc. Also, the foundation 12 is not limited to a spread foundation, but may be a pile foundation, etc.

[0024] (Wooden structure) The wooden structure 20 has a plurality of wooden frames 22 supported by the foundation 12. Each wooden frame 22 has a wooden column 24 and a wooden beam 26 joined to the wooden column 24. The wooden columns 24 and the wooden beams 26 are formed from wood.

[0025] The wooden structures 22 are assembled in a three-dimensional lattice shape (jungle gym shape). In other words, the wooden structures 22 are joined in a rectangular parallelepiped shape (cubic lattice shape) and are appropriately combined vertically and horizontally. An adjacent structure 40 is joined to this wooden structure 20.

[0026] The wooden structure 20 assembled in a three-dimensional lattice shape (jungle gym shape) may have at least one set of a plurality of wooden frames 22 joined in a rectangular parallelepiped shape (cubic lattice shape).

[0027] (adjacent structures) The adjacent structure 40 is, for example, made of reinforced concrete and is capable of bearing the seismic force of the structure 10. The adjacent structure 40 has a plurality of perimeter frames (not shown) arranged along the perimeter of the wooden structure 20, a plurality of earthquake-resistant walls 42 provided within the structural surface of the perimeter frames, and a roof slab 44 arranged on the upper side of the wooden structure 20. The earthquake-resistant walls 42 and the roof slab 44 are examples of earthquake-resistant elements.

[0028] The multiple outer perimeter frames are, for example, made of reinforced concrete. Each outer perimeter frame is a rigid frame having a pair of columns and upper and lower beams erected on the pair of columns, and is erected on the foundation 12. The multiple outer perimeter frames surround the wooden structural body 20 in plan view and support the outer periphery of the roof slab 44. A seismic wall 42 is provided within the structural surface of these outer perimeter frames.

[0029] The multiple earthquake-resistant walls 42 are, for example, made of reinforced concrete. The multiple earthquake-resistant walls 42 form the outer walls of the structure 10, and in plan view, together with the outer periphery frame, surround the wooden structural body 20. The number and arrangement of the outer periphery frame and the earthquake-resistant walls 42 can be changed as appropriate.

[0030] The roof slab 44 is, for example, made of reinforced concrete. The roof slab 44 constitutes the roof of the structure 10, and covers the entire wooden structural body 20 from above.

[0031] The outer perimeter frame is not limited to reinforced concrete construction, and may be, for example, steel-framed reinforced concrete construction, steel-frame construction, or CFT construction. The earthquake-resistant walls 42 and roof slab 44 are not limited to reinforced concrete construction, and may be, for example, steel. In other words, the adjacent structure 40 may be any construction other than wooden construction, and may be reinforced concrete construction, steel-framed reinforced concrete construction, steel-frame construction, CFT construction, or a mixed structure of at least two of these constructions.

[0032] Here, the wooden structure 20 is joined to the adjacent structure 40 so as to be capable of transmitting seismic forces. Specifically, as shown in Figures 2(A) and 2(B), the ends of the wooden beams 26 of the wooden structure 20 are joined to fixing brackets 50 fixed to the inner wall surface of the seismic wall 42 of the adjacent structure 40 by so-called steel plate insertion drift pin joints.

[0033] The fixing bracket 50 has a base plate 52 disposed along the inner wall surface of the earthquake-resistant wall 42, and a pair of insertion plates 54 protruding from the base plate 52. The base plate 52 is formed from a steel plate or the like, and is fixed with nuts 58 to anchor bolts 56 embedded in the earthquake-resistant wall 42.

[0034] The pair of insertion plates 54 are made of steel plates or the like, and are inserted into a pair of slits (grooves) 28 formed in the end of the wooden beam 26. A plurality of through holes are formed in each of the pair of insertion plates 54 and the end of the wooden beam 26. The pair of insertion plates 54 and the end of the wooden beam 26 are joined to each other by inserting drift pins 60 into each of these through holes.

[0035] The gap between the base plate 52 and the inner wall surface of the earthquake-resistant wall 42 and the gap between the base plate 52 and the end surface of the wooden beam 26 are filled with a filler 62 such as mortar or grout.

[0036] The earthquake-resistant wall 42 and the wooden beam 26 may be joined in any manner so long as they are capable of transmitting earthquake forces, and the joining structure may be modified as appropriate. The wooden beam 26 may be joined not only to the earthquake-resistant wall 42, but also to the outer frame of the adjacent structure 40 so as to transmit earthquake forces.

[0037] (Wall unit) 3, a wall unit 70 is detachably attached to the wooden structure 20. Specifically, a plurality of wall units 70 are detachably attached to the wooden frame 22 of the wooden structure 20. The plurality of wall units 70 are formed, for example, from wood panels.

[0038] It should be noted that the wall unit 70 is not limited to being made of a wood panel, and may be made of, for example, an ALC panel, a metal panel, a concrete panel, or the like.

[0039] The multiple wall units 70 are arranged in the width direction of the wooden frame 22. As shown in Fig. 4, the ends of adjacent wall units 70 are connected by half-length joints that fit together in the wall thickness direction.

[0040] Specifically, a notch 72 is formed in each end of adjacent wall units 70, into which the end of the other unit is disposed. The ends of adjacent wall units 70 are overlapped in the wall thickness direction via a cushioning material 74 such as a rubber sheet. In this state, the ends of adjacent wall units 70 are joined together by bolts 76 and nuts 78 that pass through each of the ends in the wall thickness direction.

[0041] Although a countersunk hole 79 for accommodating a nut 78 is formed on the surface (outer surface) of the wall unit 70, the countersunk hole 79 can be omitted as appropriate. Also, the buffer material 74 can be provided as necessary and can be omitted as appropriate.

[0042] Furthermore, the ends of adjacent wall units 70 may be connected to each other by other joint structures other than a half-length joint.

[0043] (Wall bracket) 5, the upper and lower ends of the wall unit 70 are detachably attached to the wooden beam 26 via a wall bracket 80. The wall bracket 80 is detachably attached to the upper surface 26U and the lower surface 26L of the wooden beam 26 by a plurality of through bolts 84 that penetrate the wooden beam 26 in the beam formation direction.

[0044] The wall bracket 80 fixed to the upper surface 26U of the wooden beam 26 and the wall bracket 80 fixed to the lower surface 26L of the wooden beam 26 are configured symmetrically above and below the wooden beam 26. Therefore, in the following, the configuration of the wall bracket 80 fixed to the upper surface 26U of the wooden beam 26 will be described, and a description of the configuration of the wall bracket 80 fixed to the lower surface 26L of the wooden beam 26 will be omitted.

[0045] A plurality of through holes 30 are formed in the wooden beam 26. The plurality of through holes 30 are circular holes that penetrate the wooden beam 26 in the beam formation direction, and open to an upper surface 26U and a lower surface 26L of the wooden beam 26. Through bolts 84 are slidably inserted through the through holes 30.

[0046] The upper ends of the through-bolts 84 protrude upward from the upper surface 26U of the wooden beam 26. Similarly, the lower ends of the through-bolts 84 protrude downward from the lower surface 26L of the wooden beam 26. Male threads are provided on both ends of the through-bolts 84, into which nuts 86, described below, can be fastened. The through-bolts 84 are an example of a wall mounting member.

[0047] The wall bracket 80 is formed with a C-shaped cross section. The wall bracket 80 has a base portion 80A fixed to the upper surface 26U of the wooden beam 26, and a pair of holding portions 80B that hold the ends (lower ends) of the wall unit 70.

[0048] The base portion 80A is disposed along the upper surface 26U of the wooden beam 26. A plurality of mounting holes 82 are formed in the base portion 80A. The plurality of mounting holes 82 are circular holes that penetrate the base portion 80A in the thickness direction.

[0049] The upper ends of a plurality of through-bolts 84 protruding from the upper surface 26U of the wooden beam 26 are inserted into the plurality of mounting holes 82. The base portion 80A is fixed to the upper surface 26U of the wooden beam 26 by fastening nuts 86 to the upper ends of the through-bolts 84.

[0050] The pair of retaining portions (retaining wall portions) 80B extend upward from both ends of the base portion 80A in the beam width direction of the wooden beam 26. The pair of retaining portions 80B face each other in the beam width direction of the wooden beam 26 (wall thickness direction of the wall unit 70) with the wall unit 70 between them. The pair of retaining portions 80B retain the lower end of the wall unit 70 from both sides in the wall thickness direction.

[0051] The lower end of the wall unit 70 is placed on the base portion 80A via a spacer (not shown) so as not to interfere with the upper end of the through-bolt 84.

[0052] 3, when installing the wall unit 70, first, a plurality of wall brackets 80 are attached to the upper and lower wooden beams 26 by a plurality of through-bolts 84 that penetrate the wooden beams 26 in the beam formation direction. At this time, the wooden beams 26 may be formed with through-holes 30 for passing the through-bolts 84 therethrough, if necessary.

[0053] Next, the wall unit 70 is placed between the wall brackets 80 adjacent in the material axis direction of the wooden beam 26. Then, the wall unit 70 is slid along the wooden beam 26 toward the wooden column 24, and the upper and lower ends of the wall unit 70 are held by the upper and lower wall brackets 80, respectively.

[0054] Next, the wall units 70 are placed between the wall brackets 80 adjacent in the material axis direction of the wooden beams 26. At this time, as shown in Fig. 4, the ends of adjacent wall units 70 are combined in the wall thickness direction via buffer materials 74 and connected by a half-edge joint. In this state, the ends of adjacent wall units 70 are joined by bolts 76 and nuts 78.

[0055] On the other hand, when removing the wall units 70, the above procedure is reversed. That is, first, the bolts 76 and nuts 78 are removed from the ends of adjacent wall units 70. Next, as shown in Figures 3 and 5, the wall units 70 are sequentially removed from between adjacent wall brackets 80 in the material axis direction of the wooden beams 26. Next, the through-bolts 84 and nuts 86 are removed from the wooden beams 26 and the wall brackets 80, and the wall brackets 80 are removed.

[0056] The number and arrangement of the wall units 70 arranged within the structural surface of the wooden frame 22 can be changed as appropriate. Also, within the structural surface of the wooden frame 22, it is possible to arrange large wall units that span adjacent wooden columns 24.

[0057] In this embodiment, the through-bolts 84 and nuts 86 are used by the wall brackets 80 fixed to the upper surface 26U and the lower surface 26L of the wooden beam 26. However, the wall brackets 80 fixed to the upper surface 26U and the lower surface 26L of the wooden beam 26 may be fixed to the wooden beam 26 by separate through-bolts 84 and nuts 86.

[0058] In addition, the wall bracket 80 is not limited to being attached to the wooden beam 26, but may be removably attached to the wooden pillar 24.

[0059] (Floor unit) As shown in Fig. 6, a floor unit 90 is detachably attached to the wooden structure 20. Specifically, the floor unit 90 is detachably attached to the wooden frame 22 of the wooden structure 20. The floor unit 90 is formed of a wood panel, for example.

[0060] The floor unit 90 is not limited to being made of a wood panel, and may be made of, for example, an ALC panel, a metal panel, a concrete panel, or the like.

[0061] (Floor bracket) The outer periphery of the floor unit 90 is detachably attached to the wooden beam 26 via a plurality of floor brackets 100. The plurality of floor brackets 100 are detachably attached to the side surface 26S of the wooden beam 26 by a plurality of through bolts 104 that penetrate the wooden beam 26 in the beam width direction.

[0062] 7, a plurality of through holes 32 are formed in the wooden beam 26. The plurality of through holes 32 are circular holes that penetrate the wooden beam 26 in the beam width direction, and open on both side surfaces 26S of the wooden beam 26. A through bolt 104 is slidably inserted through each of the through holes 32.

[0063] Both ends of the multiple through-bolts 104 protrude from the side surface 26S of the wooden beam 26. Male threads are provided on both ends of the through-bolts 104, and nuts 106, which will be described later, can be tightened into the through-bolts 104. The through-bolts 104 are an example of a floor mounting member.

[0064] The floor bracket 100 is formed with an L-shaped cross section. The floor bracket 100 has a base portion 100A fixed to the side surface 26S of the wooden beam 26, a support portion 100B that supports the underside of the floor unit 90, and a reinforcing rib portion 100C that reinforces the support portion 100B.

[0065] The base portion 100A is disposed along the side surface 26S of the wooden beam 26. A plurality of mounting holes 102 are formed in the base portion 100A. The plurality of mounting holes 102 are circular holes that penetrate the base portion 100A in the thickness direction.

[0066] Ends of a plurality of through-bolts 104 protruding from a side surface 26S of the wooden beam 26 are inserted into the mounting holes 102. Nuts 106 are fastened to the ends of the through-bolts 104, respectively, so that the base portion 100A is fixed to the side surface 26S of the wooden beam 26.

[0067] The support portion (receiving portion) 100B protrudes substantially horizontally from the upper end portion of the base portion 100A toward the side of the wooden beam 26. The outer periphery of the floor unit 90 is placed on the upper surface of this support portion 100B. In addition, the upper end portion of a reinforcing rib portion 100C protruding from the outer surface of the base portion 100A is joined to the lower surface of the support portion 100B.

[0068] Here, when installing the floor unit 90, first, a plurality of floor brackets 100 are detachably attached to the wooden beams 26 by a plurality of through-bolts 104 that penetrate the wooden beams 26 in the beam width direction. At this time, the wooden beams 26 may be formed with through-holes 32 for passing the through-bolts 104 therethrough, as necessary.

[0069] Next, the outer periphery of the floor unit 90 is placed on the upper surfaces of the support parts 100B of the multiple floor brackets 100. Note that the outer periphery of the floor unit 90 may be placed on the upper surfaces of the support parts 100B of the floor bracket 100 via a non-slip mat or the like.

[0070] On the other hand, when removing the floor unit 90, the above procedure is reversed. That is, first, the floor unit 90 is removed from above the support parts 100B of the multiple floor brackets 100. Next, the through bolts 104 and nuts 106 are removed from the wooden beams 26 and the floor brackets 100, and the floor brackets 100 are removed.

[0071] In this embodiment, the through-bolts 104 and nuts 106 are used for the wall brackets 80 fixed to both side surfaces 26S of the wooden beam 26. However, the floor brackets 100 fixed to both side surfaces 26S of the wooden beam 26 may be fixed to the wooden beam 26 by separate through-bolts 104 and nuts 106.

[0072] Furthermore, the floor bracket 100 is not limited to being attached to the wooden beam 26, but may be detachably attached to the wooden pillar 24.

[0073] (Staircase unit) As shown in Figures 8 and 9, a staircase unit 110 is detachably attached to the wooden structure 20. Specifically, the staircase unit 110 is detachably attached to the wooden frame 22 of the wooden structure 20. As an example, this staircase unit 110 is installed on a predetermined floor of the structure 10, and serves as a turn-back staircase that turns back at the middle of the floor height.

The base plate 126 is formed of a steel plate or the like, and is disposed along a side surface 26S of the wooden beam 26. A washer plate (bearing plate) 128 is disposed on the side surface 26S of the wooden beam 26 opposite the base plate 126. A plurality of mounting holes 130 are formed in each of the base plate 126 and the washer plate 128.

[0079] The multiple mounting holes 130 are circular holes that penetrate the base plate 126 or the washer plate 128 in the thickness direction. Both ends of multiple through-bolts 132 that protrude from the side surface 26S of the wooden beam 26 penetrate through these mounting holes 130. The base plate 126 is fixed to the side surface 26S of the wooden beam 26 by tightening nuts 134 to both ends of these through-bolts 132.

[0080] 8 and 9, the landing 124 of the lower staircase 120 extends outwardly from the upper end of the staircase 122 in a generally horizontal manner, with its tip located above the wooden beam 26. This landing 124 is supported by a number of landing supports 150, which will be described later.

[0081] (upper stairs) The upper staircase 140 has a staircase section 142 and a landing section 144 provided at the lower end of the staircase section 142. The staircase section 142 has a pair of stringers 142A and a plurality of treads 142B mounted on the pair of stringers 142A. The upper end of the staircase section 142 is detachably attached to the upper wooden beam 26 on a predetermined floor of the structure 10 by a plurality of through bolts 132 that penetrate the wooden beam 26 in the beam width direction.

[0082] The joint structure between the upper end of the stair section 142 of the upper staircase 140 and the wooden beam 26 is similar to the joint structure between the lower end of the stair section 122 of the lower staircase 120 described above and the wooden beam 26, so explanation will be omitted.

[0083] The landing section 144 of the upper staircase 140 protrudes outwardly substantially horizontally from the lower end of the staircase section 142, and is located above the wooden beams 26. The landing section 144 is disposed adjacent to and continuous with the landing section 124 of the lower staircase 120. The tip of the landing section 144 is supported by a plurality of landing supports 150.

[0084] (Landing support) As shown in Fig. 8, the landing supports 150 are formed of, for example, shaped steel such as H-shaped steel or steel pipes.

The base plate 152 is formed of a steel plate or the like, and is disposed along the side surface 26S of the wooden beam 26. A washer plate (bearing plate) 154 is disposed on the lower surface 26L of the wooden beam 26. The base plate 152 and the washer plate 154 each have a plurality of mounting holes 156 formed therein.

[0088] The multiple mounting holes 156 are circular holes that penetrate the base plate 152 or the washer plate 154 in the thickness direction. Both ends of multiple through-bolts 160 that protrude from the upper surface 26U or the lower surface 26L of the wooden beam 26 penetrate through these mounting holes 156. The base plate 152 is fixed to the upper surface 26U of the wooden beam 26 by tightening nuts 162 to both ends of these through-bolts 160.

[0089] The tips of the landing sections 124, 144 of the lower staircase 120 and the upper staircase 140 are placed on the upper ends of the multiple landing supports 150. The landing sections 124, 144 of the lower staircase 120 and the upper staircase 140 are supported by these landing supports 150.

[0090] The number and arrangement of the landing support 150 can be changed as appropriate. The staircase unit 110 of this embodiment also has the landing sections 124, 144 and the landing support 150. However, the landing sections 124, 144 and the landing support 150 may be provided as necessary and may be omitted as appropriate.

[0091] In this embodiment, the staircase unit 110 is a return staircase. However, the staircase unit 110 is not limited to a return staircase, and may be, for example, a spiral staircase, a spiral staircase, a straight staircase, or the like.

[0092] (action) Next, the operation of this embodiment will be described.

[0093] As shown in Fig. 1, according to this embodiment, a wooden structure 20 has a plurality of wooden frames 22 formed by wooden columns 24 and wooden beams 26. This wooden structure 20 is adjacent to an adjacent structure 40. The adjacent structure 40 has a plurality of earthquake-resistant walls 42 and a roof slab 44 as earthquake-resistant elements, and is connected to the wooden structure 20.

[0094] Here, the wall units 70, the floor units 90, and the staircase units 110 are detachably attached to the wooden structure 20. This makes it easy to change the layout of the wall units 70, the floor units 90, and the staircase units 110 and to add or remove them. Therefore, in this embodiment, the plan and use of the structure 10 can be easily changed, and the freedom to change the plan, use, etc. is improved.

[0095] On the other hand, the wooden structure 22 may lack earthquake resistance performance compared to a reinforced concrete structure.

[0096] In contrast, in this embodiment, an adjacent structure 40 having a seismic wall 42 and the like is joined to the wooden structure 20. By making the adjacent structure 40 bear the seismic force, the seismic performance of the wooden structure 20 can be ensured.

[0097] 5, the wall unit 70 is supported by a wall bracket 80. The wall bracket 80 is detachably attached to the wooden beam 26 by a through-bolt 84 passing through a through-hole 30 formed in the wooden beam 26.

[0098] 7, the floor unit 90 is supported by a floor bracket 100. The floor bracket 100 is detachably attached to the wooden beam 26 by a through bolt 104 passing through a through hole 32 formed in the wooden beam 26.

[0099] 10, the lower staircase 120 and the upper staircase 140 of the staircase unit 110 are detachably attached to the wooden beam 26 by through-bolts 132 that pass through through-holes 34 formed in the wooden beam 26. Furthermore, as shown in FIG. 11, the landing support 150 of the staircase unit 110 is detachably attached to the wooden beam 26 by through-bolts 160 that pass through through-holes 36 formed in the wooden beam 26.

[0100] Here, compared to reinforced concrete beams, it is easier to form the through holes 30, 32, 34, 36 for passing the through bolts 84, 104, 132, 160 in the wooden beams 26. Moreover, the through holes 30, 32, 34, 36 can be easily formed in the existing wooden beams 26.

[0101] Therefore, in this embodiment, the wall brackets 80, the floor brackets 100, the lower staircase 120, the upper staircase 140, and the landing posts 150 can be easily and detachably attached to the wooden beams 26. Therefore, in this embodiment, it becomes easier to change the layout of the wall units 70, the floor units 90, and the staircase units 110 and to add or remove them.

[0102] Furthermore, the wooden frames 22 are assembled in a three-dimensional lattice shape. The wall units 70, floor units 90, and staircase units 110 can be attached and detached to the wooden frames 22 assembled in a three-dimensional lattice shape in this way, thereby increasing the freedom of the plan of the structure 10.

[0103] (Modification) Next, a modification of the above embodiment will be described.

[0104] In the above embodiment, the staircase unit 110 is removably attached to the wooden structure 20 of the structure 10. However, the staircase unit 110 may be provided in the wooden structure 20 as necessary and may be omitted as appropriate. In addition, when the staircase unit 110 is omitted, for example, a staircase 170 may be provided in the structure 40 adjacent to the structure 10, as in the modified example shown in FIG.

[0105] In the above embodiment, the wall mounting members, floor mounting members, stair mounting members, and post mounting members are through-bolts 84, 104, 132, and 160. However, the wall mounting members, floor mounting members, stair mounting members, and post mounting members are not limited to through-bolts 84, 104, 132, and 160, and may be PC steel bars, PC steel wires, or the like.

[0106] In the above embodiment, the wall bracket 80 and the floor bracket 100 are detachably attached to the wooden beam 26 by the through bolts 84, 104. However, the wall bracket 80 and the floor bracket 100 may be detachably attached to the wooden beam 26 by, for example, wood screws, etc., without being limited to the through bolts 84, 104. The structures of the wall bracket 80 and the floor bracket 100 can be modified as appropriate.

[0107] In the above embodiment, the wall unit 70 is detachably attached to the wooden beam 26 via the wall bracket 80. However, the wall unit 70 may be detachably attached to the wooden beam 26 via other members, not limited to the wall bracket 80. For example, a base plate similar to the base plate 152 of the landing support 150 may be provided at the end of the wall unit, and the base plate may be detachably attached to a through-bolt or the like that penetrates the wooden beam 26.

[0108] Similarly, the floor unit 90 may be detachably attached to the wooden beam 26 via other members, not limited to the floor bracket 100. For example, the floor unit may be detachably attached to the wooden beam 26 by placing an end of the floor unit on the upper surface of the wooden beam 26 and using a through bolt or the like that penetrates the floor unit and the wooden beam 26 in the beam formation direction.

[0109] In the above embodiment, the adjacent structure 40 is disposed along the periphery of the wooden structure 20 in a plan view, and surrounds the wooden structure 20. However, the adjacent structure 40 only needs to be disposed adjacent to the wooden structure 20 and joined to the wooden structure 20 so as to be capable of transmitting seismic force, and may be disposed along a predetermined side of the wooden structure 20 in a plan view, or along two predetermined sides of the wooden structure 20. In other words, the adjacent structure 40 can be disposed along at least a part of the periphery of the wooden structure 20 in a plan view. In addition, from the viewpoint of bearing seismic force, it is preferable that the adjacent structure 40 is disposed along at least one side of the wooden structure 20 in a plan view.

[0110] In the above embodiment, the earthquake-resistant elements of the adjacent structure 40 are the earthquake-resistant walls 42 and the roof slab 44. However, the earthquake-resistant elements are not limited to the earthquake-resistant walls 42 and the roof slab 44, and may be, for example, braces. In the above embodiment, the roof slab 44 is the earthquake-resistant element, but the roof slab 44 does not have to be an earthquake-resistant element.

[0111] In the above embodiment, the wooden frames 22 are assembled in a three-dimensional lattice shape. However, the wooden frames 22 do not necessarily have to be in a three-dimensional lattice shape, and the assembled structure can be changed as appropriate.

[0112] Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and one embodiment and various modified examples may be used in appropriate combination, and it is of course possible to implement the present invention in various forms without departing from the gist of the present invention.
